Abstract
The utility model discloses an angle steel drilling and compressing device, which comprises a bracket, a pressing oil cylinder, two supporting bodies used for supporting angle steel and a pressing plier which is arranged above the supporting bodies and can compress the angle steel tightly at both sides of a drill bit, the two supporting bodies are arranged at both sides of the drill bit, the pressing oil cylinder is fixed on the bracket, and the pressing plier is connected with a cylinder rod of the pressing oil cylinder. The device adopts a centering pressing device; and when the end parts of an angle steel component are drilled, the angle steel component is not in a suspending state, thereby effectively solving the problem of damaging the drill bit caused by insufficient rigidity of the angle steel component and improving the service life of the drill bit.
Description
(1) technical field
The utility model relates to a kind of boring hold down gag, particularly a kind of hold down gag to the boring of angle steel both wings face.
(2) background technology
At present, known hold down gag to the boring of angle steel both wings face is distributed in the both sides of drill bit, during boring workpiece is compressed.The spacing distance that two covers compress device is bigger, when holing for the end of angle iron component, can only have a cover to compress the device workpiece pressing, and workpiece is in cantilever position, the rigidity deficiency of angle iron component.During boring, drill bit is damaged easily, reduces the service life of drill bit, and is when particularly adopting carbide drill to hole, especially obvious to the damage of drill bit.
(3) summary of the invention
The technical problems to be solved in the utility model is: providing a kind of can make it can improve the service life of drill bit to the angle steel boring hold down gag of angle steel centering clamping.
In order to solve the problems of the technologies described above, the utility model comprises that support, binder oil cylinder, two are used to support the supporter of angle steel and are arranged on the supporter and can compress the pressing tongs that angle steel is positioned at position, drill bit both sides, two supporter branches are in the both sides of drill bit, the binder oil cylinder is fixed on the support, and pressing tongs is connected with the piston rod of binder oil cylinder.
In order to make the pressing tongs motion steadily, described pressing tongs is connected by slide plate with the piston rod of binder oil cylinder, and the both sides of slide plate are provided with the guide plate that is fixed on the support.
In order to guarantee not get on the pressing tongs behind the saturating angle steel of bit drills, the bit central on the bottom surface of described pressing tongs right position to fovea superior.
For the ease of making, described pressing tongs comprises two outer nippers and is fixed on interior nipper between the two outer nippers, and three nippers are arranged on the angle steel length direction, and two outer nipper bottom level are identical, and the bottom of interior nipper is higher than the bottom of two outer nippers.
It is simple in structure, support is reliable in order to make, and described each supporter comprises two gripper shoes, and two gripper shoes are fixed on the support, and the angle of two gripper shoes of each supporter is identical with the angle of angle steel.
The beneficial effects of the utility model: the utility model adopts the hold down gag to neutrality, when carrying out the boring of angle iron component end, angle iron component no longer is in cantilever position, has solved effectively because of the not enough damage that causes drill bit of angle iron component self rigidity, the service life of improving drill bit.
(4) description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 looks schematic diagram for the left side of Fig. 1.
Among the figure: 1, binder oil cylinder, 2, slide plate, 3, guide plate, 4, outer nipper, 5, support plate, 6, riser, 7, drill bit, 8, angle steel, 9, interior nipper.
