As shown in connection with fig. 1-4, the present application protects a five-axis head 10 while also protecting a machining center that includes the five-axis head 10 described above. It will be appreciated that the five-axis head 10 is the core tooling component of the machining center.

In some embodiments, the five-axis head 10 includes a body 100 and a cooling structure. The body 100 includes a drive assembly 110 and a cutter head assembly 120. The driving assembly 110 is connected with the tool bit assembly 120 to drive the tool bit assembly 120 to move. The cutter head assembly 120 includes a protective case 121, a cutter head driving member (not shown) mounted in the protective case 121 and connected with the cutter head 123 to drive the cutter head 123 to rotate, and a cutter head 123. The protective case 121 has a mounting surface 121a, and a liquid outlet 121b is provided at a position close to the cutter head 123. The cooling structure includes a first cooling circuit (not shown), a second cooling circuit (not shown), and a cooling assembly 200. The cooling module 200 is detachably mounted on the mounting surface 121a, and the first cooling pipeline extends inside the body 100 and is connected with the cooling module 200 at the mounting surface 121 a. The second cooling pipe extends inside the body 100 and is communicated with the liquid outlet 121b, and the flow rate of the first cooling pipe is greater than that of the second cooling pipe.

In the above-mentioned five-axis head 10, the cutter head 123 moves to drive the cutter mounted on the cutter head 123 to change the position under the co-driving of the driving assembly 110 and the cutter head driving member, so as to change the machining angle and the machining position of the cutter to the workpiece. In addition, by providing the mounting surface 121a on the protective case 121 and providing the liquid outlet 121b at a position close to the cutter head 123, the cooling liquid introduced through the first cooling line is led out through the cooling module 200 mounted on the mounting surface 121a, and the cooling liquid introduced through the second cooling line is led out through the liquid outlet 121b, so that the five-axis head 10 has a structure in which two sets of cutters can be cooled. In addition, the two groups of structures can move along with the tool bit assembly 120 under the driving of the driving assembly 110, so that when the tool is used for machining workpieces with any size, the two groups of structures can keep consistent with the machining path of the tool to cool the tool, and the applicability is high. Further, for the two sets of structures, since the flow of the first cooling pipeline is greater than the flow of the second cooling pipeline, when the tool is in the processing environment with less cooling liquid demand, the cooling liquid can be introduced through the second cooling pipeline and sprayed out through the liquid outlet 121b to cool the tool, and when the tool is in the processing environment with more cooling liquid demand, the cooling liquid can be introduced through the first cooling pipeline and led out through the cooling assembly 200 to cool the tool, so that different structures can be selected to cool according to the cooling demand of the tool, thereby being beneficial to saving the use of the cooling liquid.

In this application, the liquid outlets 121b are plural, and the liquid outlets 121b may be disposed along the circumferential direction of the cutter head 123 at intervals, so as to perform a better cooling function on the cutter mounted on the cutter head 123.

In this application, the driving assembly 110 includes a first assembly 111 and a second assembly 112, the first assembly 111, the second assembly 112 and the cutter head assembly 120 are smoothly connected, the first assembly 111 can drive the second assembly 112 to rotate around a first axis 113, the second assembly 112 can drive the cutter head assembly 120 to rotate around a second axis 114, and the second axis 114 is inclined relative to the first axis 113.

Specifically, the first assembly 111 includes a support plate 111a, a first driving member 111b, and a first rotating shaft 111c, where the first rotating shaft 111c is rotatably connected to the support plate 111a, and the first driving member 111b is mounted on the support plate 111a and connected to the first rotating shaft 111c through cooperation of a driving wheel and a conveyor belt, so as to drive the first rotating shaft 111c to rotate around the first axis 113 relative to the support plate 111 a. The first rotating shaft 111c is connected to the second component 112, so as to drive the second component 112 to rotate integrally relative to the support plate 111 a.

Specifically, in the present application, the first cooling line is led out through the internal space of the first rotating shaft 111c and communicates with an external liquid supply device. The second cooling pipe is provided at its end with a pipe joint 290 at the support plate 111a so that an external pipe can be connected to the pipe joint 290 to supply the second cooling pipe with the cooling liquid.

For the second assembly 112, it includes a housing (not shown), a second driving member (not shown) and a second rotating shaft (not shown), the second rotating shaft is rotatably connected with the housing, the second driving member is mounted on the housing and is connected with the second rotating shaft through cooperation of the driving wheel and the conveyor belt, so as to drive the second rotating shaft to rotate around the second axis 114 relative to the housing. The second rotating shaft is connected with the tool bit assembly 120, so that the tool bit assembly 120 is driven to integrally rotate relative to the housing.

It will be appreciated that the housing covers the outer periphery of the second driving member and the second rotating shaft, thereby forming an installation space inside, and protecting the internally installed structure. In other embodiments, the support plate 111a may have a shell structure like the outer shell.

It will be appreciated that tilting the second axis 114 relative to the first axis 113 means that the second axis 114 is neither perpendicular nor parallel to the first axis 113, thereby allowing a greater range of motion of the cutter head assembly 120 under the combined action of the first and

second drive members

111b, 113.

Further, the mounting surface 121a is disposed adjacent to the second assembly 112, and the cutter head 123 is located on a side of the mounting surface 121a facing away from the second assembly 112, and is spaced apart from the mounting surface 121 a. It will be appreciated that the mounting surface 121a is disposed closer to the second assembly 112 than the cutting head 123 is, and specifically, the mounting surface 121a is disposed closer to the junction between the cutting head assembly 120 and the second assembly 112 than the cutting head assembly 123, so that the cooling assembly 200 mounted on the mounting surface 121a has a smaller movement amplitude relative to the cutting head 123 under the driving of the second assembly 112, thereby avoiding the cooling liquid led out by the cooling assembly 200 from splashing and being unable to cool the cutting tool. In this application, mounting surface 121a is a flat surface inclined toward cutting head 123, which may facilitate the cooling fluid directed from cooling assembly 200 toward the contact location of the tool with the work piece for better cooling.

With continued reference to fig. 1 to 4, in particular, in the embodiment of the present application, the cooling assembly 200 includes a mounting frame 220, a sprayer 230, and a water-cooled base 240, wherein the mounting frame 220 is detachably mounted on the mounting surface 121a, and the sprayer 230 and the water-cooled base 240 are detachably mounted on the mounting frame 220. By providing the mounting bracket 220 and detachably connecting the mounting bracket 220 to the mounting surface 121a, replacement of the entire cooling assembly 200 may be facilitated. By detachably connecting the atomizer 230 and the water cooling base 240 to the mounting frame 220, respectively, maintenance or replacement can be performed by detachment when any one of the atomizer 230 and the water cooling base 240 fails. It will be appreciated that the sprayer 230 is used for guiding out oil mist with cooling effect, and the water-cooled base 240 is used for guiding out water with cooling effect, so that when the tool is processed, the oil mist cooling and the water spray cooling are performed simultaneously, and the cooling effect can be improved to a greater extent.

Specifically, in the present application, the mounting bracket 220 includes a first mounting plate 221 that is closely attached to the mounting surface 121a, and a second mounting plate 222 that is connected to a side of the first mounting plate 221 that faces away from the mounting surface 121a, the atomizer 230 is mounted to the second mounting plate 222, and the water-cooled base 240 is screwed to the first mounting plate 221 through its own screw hole.

Specifically, the cooling assembly 200 includes a first bamboo joint pipe 250 and a second bamboo joint pipe 260, the first bamboo joint pipe 250 is connected with the atomizer 230 and is used for spraying oil mist, and the second bamboo joint pipe 260 is connected with the water-cooled base 240 and is used for spraying water. It can be understood that the first bamboo joint pipe 250 and the second bamboo joint pipe 260 have the characteristic of bending and deforming, so that the oil mist guided by the atomizer 230 changes the spraying direction after being conducted by the first bamboo joint pipe 250, and the water guided by the water cooling base 240 changes the spraying direction after being conducted by the second bamboo joint pipe 260. Specifically in this application, according to the length of the cutter installed on the cutter head 123, the end, far away from the sprayer 230, of the first bamboo joint pipe 250 can be adjusted to be close to the head of the cutter, and the end, far away from the water cooling base 240, of the second bamboo joint pipe 260 can be adjusted to be close to the head of the cutter, so that the oil mist sprayed by the first bamboo joint pipe 250 and the water sprayed by the second bamboo joint pipe 260 can be guided to the contact position of the cutter and the workpiece together, and a better cooling effect is achieved on the cutter and the workpiece.

Specifically, in the present application, the lengths of the first bamboo node pipe 250 and the second bamboo node pipe 260 are 200mm. It will be appreciated that the lengths of the first and second

bamboo node tubes

250, 260 are too long to easily shake during movement with the cutter head assembly 120 to be beneficial to stably pointing to the head of the cutter, while too short to easily match cutters of various lengths. Specifically, in the present application, the liquid outlet hole at the end of the first bamboo joint pipe 250 and the water outlet hole at the end of the second bamboo joint pipe 260 are tapered holes, so as to facilitate converging oil mist and water to increase the injection pressure, so as to facilitate discharging scraps generated by cutter processing, so as to directly cool the contact position of the cutter and the workpiece, and improve the cooling effect. Specifically, in the present application, two second bamboo joint pipes 260 are connected to the water-cooled base 240, so that the water spray amount can be increased.

Further, in the present application, a first switch ball valve 270 is disposed at a position of the first bamboo joint pipe 250 near the atomizer 230, and a second switch ball valve 280 is disposed at a position of the second bamboo joint pipe 260 near the water cooling base 240. By providing the first switching ball valve 270 and the second switching ball valve 280, the oil mist injection and the water flow injection can be turned on or off. In this application, both the first on-off ball valve 270 and the second on-off ball valve 280 are 1/4 inch inside-outside tooth ball valves.

Specifically, the first cooling pipeline includes an air inlet pipeline, an oil inlet pipeline and a water inlet pipeline, the sprayer 230 has an oil inlet 231 and an air inlet 232, and the oil inlet 231 and the air inlet 232 extend into the protective shell 121 and are respectively connected with the oil inlet pipeline and the air inlet pipeline in a one-to-one correspondence manner. The horizontal base has a water inlet (not shown) to which a water inlet pipe is connected. It will be appreciated that the air flow is introduced into the sprayer 230 through the air inlet pipe, and the oil is introduced into the sprayer 230 through the oil inlet pipe, so that under the action of the high-pressure air flow, the oil is broken to form oil mist, so that the oil mist has a larger contact area with the tool and the workpiece, and the cooling effect is increased. It will be appreciated that when the first cooling pipe is connected to the sprayer 230 and the water-cooled base 240, the first cooling pipe may be stretched to protrude out of the mounting surface 121a, and after the first cooling pipe is connected to the sprayer 230 and the water-cooled base 240, the sprayer 230 and the water-cooled base 240 are mounted on the mounting frame 220, so that the connection between the first cooling pipe and the sprayer 230 and the water-cooled base 240 is located inside the protective housing 121 and is not affected by splashing of processing scraps.

Further, the atomizer 230 is provided with a first regulating valve 233 and a second regulating valve 234, the first regulating valve 233 is used for regulating the flow rate of the oil entering from the oil inlet 231, and the second regulating valve 234 is used for regulating the flow rate of the gas entering from the air inlet 232. By providing the first regulating valve 233 and the second regulating valve 234, the flow rates of the oil and the gas can be respectively controlled, and the oil mist satisfying the cooling requirement can be obtained by the interaction of the oil and the gas.

In this application, there are two sprayers 230, so that the number of air inlet pipelines and oil inlet pipelines is two, two sprayers 230 are respectively connected with a first bamboo joint pipe 250, and the two first bamboo joint pipes 250 cooperate together to increase the spraying amount of oil mist.
