Description

Drilling machine clamping frame

The present invention relates to a hand-held drilling machine having a clamping frame, and more particularly to a clamping device which can make sheet metal drilling work more labor-saving and more efficient.

Sheet metal drilling operations often require a lot of physical strength. Especially for irregularly shaped objects, it is even more difficult to find the supporting points of the reaction force, which causes a lot of inconvenience. In order to assist us in implementing the sheet metal drilling operation, it is usually set on the drilling machine. A clamping frame is provided to provide a reaction force support point to facilitate the drilling operation.

As shown in FIG. 1 , it is a conventional drilling machine with a clamping frame, the drilling machine includes a drilling main body 10a, and the clamping frame 11a is provided with a set of connecting rings 110a for drilling with the main body. 10a is coupled, the clamping arm 111a is integrally formed with the socket ring 110a, and a fixing post 112a is disposed at the front end of the clamping arm 111a, and the fixing post 112a is located directly in front of the drilling path of the drill bit; As shown in the figure, when performing a drilling operation, the drilling main body 10a pushes the drill bit 101a toward the workpiece 12a by using an internal cylinder, and provides a reaction force via the fixing post 112a to cancel the generation of the drill 101a when the cutter 101a is fed. The thrust is used to achieve the purpose of drilling the sheet metal.

As shown in FIG. 3, in another conventional drilling machine having a clamping frame, the drilling machine includes a drilling main body 10b, and the clamping frame 11b is provided with a set of connecting rings 110b. The clamping arm 111b is coupled to the socket ring 110b, and the clamping arm 111b is integrally formed with a fixing post 112b. The fixing post 112b is located at the front of the drilling path. As shown in FIG. 4, when performing a drilling operation, the drilling main body 10b uses the feeding handle 14b to pull the drilling main body 10b forward, and pushes the drill 101a toward the workpiece 12a, and The fixing post 112b provides a reaction force to counteract the thrust generated when the drill bit 101a enters the knife to achieve the purpose of drilling the sheet metal.

The above two conventional drilling machines have a clamping frame, and the clamping frame is an integrated structure. When the size of the object to be processed is not met, the entire clamping frame must be replaced, which causes inconvenience in use; Another conventional "sheet metal drilling mechanism with a clamping device" is disclosed in the patent application No. 087,208, 612; as shown in Fig. 5, the main purpose of the clamping frame 11c is The socket ring 110c and the clamping arm 111c are fixedly connected by the fixing pin 113c, and the clamping arm 111c of different sizes can be replaced according to the size of the workpiece, or the mounting position of the fixing pin 113c can be adjusted to the fixing hole 114c or the The fixing holes 115c are made such that each of the clamping arms 111c is suitable for an object to be processed having a thickness within a certain range.

The clamping frame of the conventional sheet metal drilling machine is an integrated structure, or a structure in which the size of the clamping arm can be changed and the fixed position is adjusted. In order to adapt to different thicknesses of the object to be processed, it is necessary to replace the different sizes. The group clamps the frame or the clamping arm or adjusts its fixed position, causing operational inconvenience.

The clamping frame of the conventional sheet metal drilling machine, the fixed column at the end, the feeding of the drill bit The direction of the square is directly in front. Therefore, if the width of the clamping frame is too small or the drill bit is too long, the drill bit may interfere with the fixed column when the drill bit penetrates the workpiece, causing damage to the fixing post or the drill bit.

The creation provides a clamping frame improvement of a sheet metal drilling machine, comprising a set of rings, a clamping arm fixing seat, an adjusting knob, a screw, a movable clamping arm, and a plurality of fixing column structures through which a drill bit can penetrate The clamping ring is provided with a clamping arm fixing seat, the clamping arm fixing seat is provided with a guiding groove, the movable clamping arm can slide back and forth in the guiding groove, and the adjusting knob is disposed on the clamping arm The fixing base is fixed by a fixing pin. One end of the screw is fixed to the adjusting knob, and the other end is screwed into the internal thread of the movable clamping arm. The movable clamping arm end is provided with a plurality of fixing column structures through which the drill bit can pass. Thereby, a clamping frame of a drilling machine is formed.

The clamping frame provided by the creation uses a rotation adjusting knob to drive the screw to rotate, so that the screw drives the movable clamping arm to move in front or behind the guiding groove of the clamping arm fixing seat to adjust the width of the clamping frame, therefore, The creation can use different lengths of drill bits to drill holes of different thicknesses. When the drill bit penetrates through the workpiece, it can pass through a plurality of fixed column structures that can penetrate through the end of the movable clamp arm without mutual interference, causing damage to the fixture or the drill bit.
