When in use, when the workpiece is inserted into the outer side of the fixing column on the fixture, it is fixed by the threaded connection between the connecting part and the fixing part, and then fixed by the outer shape of the mounting part fixedly provided to match the workpiece, and the fixing column is provided with a plurality of positioning parts by providing a fixing groove, a first fixing hole, a second fixing hole, and a third fixing hole.

[0004] The above patent mentions the technical content that when the workpiece is inserted into the outside of the fixing column on the clamp, it is fixed by the threaded connection between the connecting part and the fixing part, and then fixed by the outer shape of the mounting part to a shape matching the processed product. Since the workpiece is inserted into the outside of the fixing column on the clamp and then fixed by the threaded connection between the connecting part and the fixing part, the clamp can only clamp workpieces of fixed size, which makes the application range of the clamp small. At the same time, it is difficult to maintain stable positioning, which makes the workpiece easy to displace during the processing, resulting in affecting the processing accuracy of the product. Utility Model Content

[0005] The purpose of the utility model is to provide a clamp with a positioning function to solve the problem that the clamps currently on the market are difficult to stably position the workpiece, as mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamp with a positioning function, comprising a fixed frame, a slide frame, a support frame, a connecting bin and an electric push rod, slide frames are welded on both sides of the fixed frame, support frames are sleeved on the outer sides of the two groups of slide frames, connecting bins are welded on the top ends of the two groups of support frames, and electric push rods are installed on the inner walls of the two groups of connecting bins by bolts.

[0009] Preferably, mounting bolts are installed inside the two groups of slides.

[0010] Preferably, a servo motor is installed inside the fixing frame by bolts, the output end of the servo motor is connected to a fixing rod via a coupling, and the top ends of both ends of the fixing rod are connected to connecting rods via rotating shafts.

[0011] Preferably, the other ends of the two groups of connecting rods are connected to fixing seats via rotating shafts, and the two groups of fixing seats are respectively welded to the outer walls of the two groups of supporting frames.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the fixture positions and clamps the workpiece, the electric push rod pushes the guide frame and the connecting seat to move, and the connecting seat pulls the L-shaped frame to rotate with the positioning frame as the axis. At the same time, the connecting seat slides on the outer wall of the guide frame, and the other end of the L-shaped frame rotates on the inner side of the guide groove to position and clamp the workpiece. The workpiece is automatically positioned by the fixture, thereby ensuring the stability of the fixture clamping the workpiece and preventing the workpiece from being displaced during the processing, thereby improving the processing accuracy of the product.

[0014] 2. When the clamp clamps the workpiece, the workpiece is placed between the two groups of connecting bins, and the fixed rod is driven to reverse by the servo motor. The fixed rod drives the two groups of connecting rods and the two groups of fixed seats to move through the rotating shaft. The two groups of fixed seats drive the two groups of support frames and the two groups of connecting bins to move. The support frames slide on the outer wall of the slide, and the workpiece is clamped by the two groups of connecting bins. By setting the servo motor, the fixed rod, the connecting rod and the fixed seat, the clamp can clamp workpieces of different sizes, so that the clamp can adapt to workpieces of different sizes, thereby expanding the scope of application of the clamp to meet the processing needs of more types of workpieces.
