[0027] Working principle: When a workpiece clamping device is used, in the initial state, the fixed clamp 1 and the base plate 101 are respectively provided with connecting grooves 103 and connecting holes 104. The connecting bolt 105 inserted into the connecting hole 104 passes through the connecting groove 103 and connects to the fixed plate 106, so as to fix the fixed clamp 1 on the base plate 101. The movable clamp 202 is installed on the inclined surface of the movable clamp seat 2 provided on the fixed clamp 1. The movable clamp 202 and the movable clamp seat 2 are provided with movable clamps. The moving groove 203 and the screw hole 201 are connected by the clamping bolt 204 so that the workpiece can be clamped by the fixed clamp 1, the moving clamp 2 and the moving clamp 202. At the same time, a slider 303 is slidably connected in the sliding groove 301 opened on the back of the moving clamp 2. The bottom and the inside of the slider 303 are respectively provided with a right angle locking block 304 and a locking rod 306, and the locking rod 306 is inserted into the limiting hole 302 so as to lock or adjust the position of the moving clamp 2.

[0028] When it is necessary to quickly adjust the position of the movable clamp 2 to clamp the workpiece, first place the workpiece on the fixed clamp 1, then hook the pull rod 309 and pull the locking rod 306 outward to release the limiting hole 302 and release the limiting of the slider 303. Then push the slider 303 and the right-angle locking block 304 upward to release the right-angle locking block 304 from the right-angle locking groove 311 and release the locking of the movable clamp 2. At this time, move the position of the movable clamp 2 left and right so that the movable clamp 202 is in contact with the other side of the workpiece. After the position adjustment is completed, release the slider 303 and the pull rod 309, so that the slider 303 moves down and pushes the right-angle locking block 304 into the corresponding right-angle locking groove 311 to lock the movable clamp seat 2. Under the push of the spring 308 and the push plate 307, the locking rod 306 is pushed into the limiting hole 302 to lock the slider 303. At this time, use a hex wrench to turn down the clamping bolt 204 to push the movable clamp 202 to further clamp and fix the workpiece. This device facilitates quick adjustment of the movable clamp seat 2 to clamp and fix the workpiece.
