the base is provided with a sliding groove, a moving block is embedded in the sliding groove, and a vertical shaft II is fixed on the moving block; a mounting hole in the center of the movable jaw seat is sleeved in the second vertical shaft and is tightly pressed by a second compression nut on the upper part of the second vertical shaft; the left end of the screw rod is connected with a handle, and the right end of the screw rod is in spherical hinge joint with the moving block after passing through a screw rod nut; the screw rod nut is fixed on the left side of the base sliding chute;

the fixed jaw seat and the movable jaw seat are externally embedded with jaws in a tenon-and-mortise structure mode, each jaw is an integral jaw with a plurality of different face-type working faces or a plurality of separate jaws with a single working face, and the face types of the working faces of the separate jaws are different.

The operation method of the utility model is as follows:

the screw rod is rotated forwards and backwards through the handle, namely the movable jaw seat is driven to be close to or far away from the fixed jaw seat through the screw rod nut and the moving block, so that the workpiece to be processed is clamped or loosened.

When the jaw is an integral jaw with a plurality of working faces with different surface types and workpieces with different shapes need to be clamped, only one or two of the compression nuts are loosened, then the integral jaw and the fixed jaw seat or the movable jaw seat thereof are rotated, so that the surface type matched with the shape of the clamping surface of the workpiece to be machined is positioned at the position of the current actual working face (the face of the fixed jaw seat opposite to the movable jaw seat), and then the compression nut is screwed down, so that the selection of the actual working faces with different surface types can be realized, and the workpieces to be machined with different shapes are machined.

If the current integral jaw does not have a working surface matched with the surface type of the workpiece to be processed, the integral jaw is detached, the integral jaw matched with the working surface matched with the surface type of the workpiece to be processed is embedded again, and the operation is repeated.

When the jaws are a plurality of separate jaws with single working faces and workpieces in different shapes need to be clamped, only one or two compression nuts are loosened, then the plurality of separate jaws and the fixed jaw seats or the movable jaw seats thereof are rotated, so that the separate jaws with the surface shapes matched with the clamping faces of the workpieces to be machined are positioned at the current actual working position (the position of the fixed jaw seats relative to the movable jaw seats), and then the compression nuts are screwed down, so that the selection of the actual working separate jaws with different surface shapes can be realized, and the workpieces to be machined in different shapes are machined. If the current multiple columnar jaws do not have the columnar jaw matched with the surface type of the workpiece to be processed, only the columnar jaw at the current working position needs to be detached, and the columnar jaw matched with the surface type of the workpiece to be processed is replaced and embedded.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model can conveniently rotate, disassemble and change different integral type jaws, or rotate, disassemble and change the columnar jaws with different surface types, so that the working surface of the jaws is matched with the clamped surfaces of workpieces with different shapes, the clamping contact area of the jaws and the workpieces is large, further regular workpieces with the clamped surfaces being flat can be firmly clamped, workpieces with various shapes can also be firmly clamped, and the processing efficiency is high and the quality is good; the workpiece is not easy to damage during clamping, the rejection rate of the workpiece is low, and the production cost of the product is low; can meet the processing requirements of factories on workpieces with various shapes.

The working surface of the jaw is a plane, a small arc concave surface, a large arc concave surface and a closed angle concave surface.

The working surfaces are easy to process, and the combination of the working surfaces of the two opposite jaws can meet the requirements of most processed workpieces.

The jaw is provided with a locking screw which locks the jaw on the fixed jaw seat or the movable jaw seat.

Therefore, the connection between the jaw and the fixed jaw seat or the movable jaw seat is firmer.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
