Preferably, the compression screw is threadedly engaged with the riser.

Preferably, there is a positioning pin on the inner side of the left vertical board.

Preferably, the inner side of the right vertical board has a push rod.

After adopting the above structure, the utility model has the advantages compared with the prior art: after putting the workpiece into the fixture, only the handle needs to be operated, and the handle is pushed into the positioning groove so that the pressing rod bears against the top plate, that is, Yes, the pressing head on the pressing plate presses the workpiece to the base in the vertical direction, and the pressing screw on the pressing plate presses the workpiece to the base in the horizontal direction, so that the workpiece is completely positioned, and the handle is withdrawn from the positioning groove after processing And pull the handle to release the pressing rod from the pressing plate to take out the workpiece. Whether it is clamping or loosening the workpiece, the operation is very convenient, which reduces the labor intensity of the processing personnel and improves production efficiency. Suitable for mass production.

Detailed ways

The following descriptions are only preferred embodiments of the present utility model, and do not therefore limit the protection scope of the present utility model.

Embodiment, see shown in Fig. 2 to Fig. 3:

The utility model is a fixture for machine tool processing, which includes a base 10, a fixed sleeve 20, a pressing rod 21 and a pressing plate 30, the two ends of the base 10 have a left vertical plate 11 and a right vertical plate 12, and the fixed sleeve 20 wears Set on the right vertical plate 12, the pressing rod 21 is inserted into the fixing sleeve 20; the fixing sleeve 20 has a positioning groove 22, and the pressing rod 21 has a handle 23 that can be snapped into the positioning groove 22 The pressing plate 30 has a horizontal plate 31 and a vertical plate 32 connected as one, the end of the horizontal plate 31 has a compression head 33, and the inner side of the vertical plate 32 has a compression screw 34 placed horizontally, so The outside of above-mentioned riser 32 is withstood by pressing bar 21. After the workpiece 40 is put into the fixture, push the handle 23 to the left, so that the compression rod 21 moves to the left to push against the vertical plate 32 of the pressure plate 30 and pushes the pressure plate 30 to move to the left. When the compression screw 34 on the vertical plate 32 contacts After reaching the workpiece 40, the pressing plate 30 will fall down under the promotion of the pressing rod 21, so that the horizontal plate 31 of the pressing plate 30 will move towards the workpiece 40, and the pressing head 33 will press on the workpiece 40, and continue to push the handle 23 to make the pressing plate 30 move toward the workpiece 40. Tighten the screw 34 and the compression head 33 to locate the workpiece 40 on the base 10, and then snap the handle 23 into the positioning groove 22 on the fixed sleeve 20, so that the compression rod 21 will not automatically move to the right. Now, the clamping head 33 and the base 10 position the workpiece 40 in the vertical direction, and the clamping screw 34 and the left vertical plate 11 position the workpiece 40 in the horizontal direction, so the workpiece 40 is completely positioned, and subsequent processing steps can be carried out . After the processing is completed, the handle 23 is withdrawn from the positioning groove 22, and the handle 23 is pulled to the right, so that the pressing rod 21 drives the pressing plate 30 to break away from the workpiece 40, and the workpiece 40 can be taken out. Therefore, the fixture of the utility model only needs to operate the handle 23 to complete the clamping and loosening of the workpiece 40 in operation, and can completely replace the fixture using screws in two directions, which is more convenient to operate and saves time and effort. It also reduces the labor intensity of processing personnel and improves production efficiency.

There may be workpieces 40 of different lengths during processing, so the compression screw 34 and the riser 32 can be threadedly matched to adjust the distance between the compression screw 34 and the workpiece 40 to meet the processing of workpieces 40 of different lengths. Require. In order to enable the workpiece 40 to be placed in the correct position in the fixture conveniently when the workpiece 40 is put into the fixture, there is a positioning pin 13 inside the left vertical plate 11, which can play the role of positioning the workpiece 40, further facilitating The workpiece 40 is clamped. When unclamping the workpiece 40, after moving the handle 23 to the right, the template 31 on the pressing plate 30 may not be tilted, so that when the workpiece 40 is taken out, the pressing head 33 can hook the workpiece 40, so that it is difficult to take out the workpiece 40 Convenient, so there is a push rod 14 on the inside of the right vertical plate 12, so that when the handle 23 is moved left and right to drive the pressing plate 30 to move to the right, after the vertical plate 32 of the pressing plate 30 touches the push rod 14, the horizontal plate 31 of the top plate will Upturned, easy to take out the workpiece 40.

The machine tool processing fixture of the utility model is very convenient in operation no matter for clamping or loosening workpieces, reduces the labor intensity of processing personnel, can also improve production efficiency, and is suitable for mass production.
