[0036] The workpiece 10a is fixed to the base 10 and is located in the extension direction of the slide groove 11, and is provided with a workpiece placement groove 21. The driving unit 40 is connected to the clamping block 30 and can drive the clamping block 30 to slide along the slide groove 11. When the workpiece 10a is clamped, the workpiece 10a is first placed in the workpiece placement groove 21, and then the clamping block 30 is driven by the driving unit 40 to slide in the direction of the retaining frame 20, and the workpiece 10a is clamped together with the retaining frame 20 to achieve the stability of the workpiece 10a. Since the clamping tool is also provided with a workpiece clamp 50, the workpiece clamp 50 can be detachably fixed to the retaining frame 20, and the workpiece 10a can be stably restricted to the workpiece placement groove 21, thereby effectively avoiding displacement and material collapse during the processing of the workpiece 10a, thereby improving the processing quality of the workpiece 10a.

[0037] It is understandable that the base 10 can be any base structure that can be stable on a machine tool.

[0038] In this embodiment, the base 10 is a fixed plate.

[0039] In this embodiment, a sliding portion 31 is provided at the bottom of the clamping block 30, and the sliding portion 31 is slidably connected to the slide groove 11 and the clamping portion. The cooperation between the sliding portion 31 and the slide groove 11 can realize the stable sliding of the clamping block 30 and limit the clamping block 30 to prevent the clamping block 30 from detaching from the base 10.

[0040] In one embodiment, the retaining frame 20 is provided with a limiting hole 22, the limiting hole 22 is opposite to the clamping block 30, and the limiting hole 22 is provided for inserting one end of the workpiece 10a to limit the workpiece 10a.

Specifically, when the clamping block 30 moves toward the stop frame 20, the rear end of the workpiece 10a is inserted into the limiting groove 32, and then the rear end of the workpiece 10a is limited, thereby reducing the vibration of the workpiece 10a during the processing, and improving the processing quality of the workpiece 10a.

[0042] It can be understood that the driving unit 40 can be any driving structure such as a motor and a screw module, a hydraulic cylinder or a cylinder that can drive the clamping block 30 to move.

The fixing portion 52 can achieve the stability of the workpiece clamp 50 and the retaining frame 20. After the workpiece 10a is processed, it is only necessary to loosen the clamping block 30 and then remove the fixing portion 52 from the retaining frame 20 to remove the workpiece 10a.

[0045] In one embodiment, the workpiece clamp 50 further includes a locking screw 53, and the retaining frame 20 is provided with a plurality of connecting holes 23. The locking screw 53 passes through the fixing portion 52 and is threadedly connected to some of the connecting holes 23.
