[0037] like Figures 1-2 As shown, the quick-conversion clamp includes a column 10, a conversion head 20, a first clamping unit 30, a second clamping unit 40 and a conversion drive unit 50. The conversion head 20 is hinged to one end of the column 10, and the conversion head 20 is provided with a first mounting end 21 and a second mounting end 22 which is at an angle to the first mounting end 21; the first clamping unit 30 is fixed to the first mounting end 21; the second clamping unit 40 is fixed to the second mounting end 22; the conversion drive unit 50 is fixed to the column 10 and connected to the conversion head 20, and is used to drive the conversion head 20 to rotate so that the first clamping unit or the second clamping unit 40 clamps the workpiece.

[0038] Specifically, the quick conversion fixture is provided with a column 10, a conversion head 20, a first clamping unit 30, a second clamping unit 40 and a conversion drive unit 50. The conversion head 20 is hinged at one end of the column 10. The conversion head 20 is provided with a first mounting end 21 and a second mounting end 22. The first clamping unit 30 and the second clamping unit 40 are respectively fixed to the first mounting end 21 and the second mounting end 22, so that during the rotation of the conversion head 20, the first clamping unit 30 and the second clamping unit 40 can be driven to rotate. The conversion drive unit 50 is connected to the conversion head 20. When the machine tool is in operation, When processing the workpiece clamped by the first clamping unit 30, the second clamping unit 40 clamps the workpiece at one of the clamping stations. After completing the processing of the workpiece of the first clamping unit 30, the conversion drive unit 50 drives the conversion head 20 to rotate, so that the second clamping unit 40 rotates to the processing position of the workpiece, and the machine tool processes the workpiece clamped by the second clamping unit 40. At the same time, the first clamping unit 30 rotates to another clamping station to clamp the workpiece at the clamping station, thereby realizing uninterrupted processing of each workpiece by the machine tool, effectively improving the processing efficiency of the workpiece.

[0039] In one embodiment, Figure 1As shown, the quick conversion clamp further includes a locking rod 60, a mounting seat 70 and a fixed seat 80.

Specifically, during the locking work of the mounting seat 70, the locking rod 60 moves toward the sliding protrusion 71 by rotating, thereby driving the locking spring 81 to fit closely with the side wall of the sliding protrusion 71, thereby converting the point contact between the locking rod 60 and the sliding protrusion 71 into the surface contact between the locking spring 81 and the sliding protrusion 71, so as to achieve stable locking of the mounting seat 70.

Specifically, the drive module 51 drives the drive rod 52 to move axially, so as to drive the conversion head 20 to rotate around the column 10, and finally realizes the driving of the first clamping unit 30 and the second clamping unit 40.

[0048] It can be understood that the driving module 51 can be any driving component such as a motor, a cylinder, etc. that can drive the driving rod 52 to move axially.

[0049] In one embodiment, Figure 1 As shown, the driving module 51 includes a hydraulic cylinder 511 , which is fixed to the column 10 and connected to the driving rod 52 .
