[0042] The staff can take out the two sets of pipe assemblies, so that the two sets of pipes pass through the two sets of drum-shaped support frames 16 and 15. When the torque motor 7 and the bevel gear driver 8 drive the long shaft 12 to rotate, the long shaft 12 will drive the first short shaft 4 and the driven gear plate 6 to rotate synchronously.

[0043] The driven gear disc 6 will drive another set of first short shafts 4 and the driving gear disc 5 to rotate, so that the symmetrical clamping components on the left and right sides of the clamp can clamp the pipe workpiece synchronously, thereby realizing the clamping function of the clamp for double workpieces and meeting the staff's multi-station force measurement detection needs.

[0044] Embodiment 3, based on embodiment 1, Figure 1 , Figure 2 and Figure 8 It is shown that two sets of ball bearing seats 11 are fixedly connected to the inner wall of one side of the first support frame 2, and one end of the long axis 12 passes through the outside of the two sets of ball bearing seats 11, and the ball bearing seats 11 improve the rotation stability of the long axis 12;

[0046] The buffer 17 includes an inverted U-shaped bracket 1701 installed at the bottom end of the ball nut pair 1301 and the sliding sleeve 103, a transverse guide rod 1702 is slidably installed inside the inverted U-shaped bracket 1701, both ends of the transverse guide rod 1702 penetrate to the outside of the inverted U-shaped bracket 1701, a baffle 1703 is fixed to one end of the transverse guide rod 1702, and the other end of the transverse guide rod 1702 is fixedly connected to the outer wall of the drum-shaped support frame 16, a baffle 2 1704 is fixed to one side of the surface of the transverse guide rod 1702, and a spring body 1705 is installed on the outer wall of one side of the baffle 2 1704, and the spring body 1705 is wound around the outer peripheral surface of the transverse guide rod 1702, and the spring body 1705 is a spiral spring or a conical spring;

[0047] When the drum-shaped support frame 2 16 and the drum-shaped support frame 1 15 clamp the pipe workpiece, the drum-shaped support frame 2 16 can push the transverse guide rod 1702 and the baffle 1 1703 to move leftward. At this time, the spring body 1705 is in a contracted state, and the pressure damage to the pipe during the clamping process is reduced through the buffer 17, thereby effectively protecting the pipe.

[0048] When the embodiment of the present application is used, the staff first takes out the pipe workpiece to be positioned, and passes the group of pipe workpieces between the drum-shaped support frame 2 16 and the drum-shaped support frame 1 15. At this time, the pipe workpiece is located on the inner wall of the drum-shaped support frame 1 15. Then the staff turns on the torque motor 7, and the torque motor 7 drives the long shaft 12 and the worm segment 1201 to rotate synchronously through the bevel gear driver 8. In this process, since several groups of worm segments 1201 are meshed with the corresponding worm gears 10, the long shaft 12 drives several groups of second short shafts 9 and ball screws 13 to rotate together. Taking three groups of ball screws 13 as an example, when the ball screw 13 rotates, the ball screw 13 can make the ball screw 13 rotate. The nut pair 1301 drives the buffer 17 and the drum-shaped support frame 16 to move toward the drum-shaped support frame 15. During this process, the lateral guide unit formed by the sleeve 103 and the guide column 102 improves the movement stability of the buffer 17. At this time, the drum-shaped support frame 16 and the drum-shaped support frame 15 can stably fix the pipeline workpiece. The clamping members formed by the multiple groups of ball screws 13, buffers 17, drum-shaped support frames 16 and drum-shaped support frames 15 on one side of the first support frame 2 can improve the fixing strength of the clamp, that is, there are multiple groups of clamping pressures on the outer wall of the pipeline, and there is no need for the staff to arrange multiple clamps, which is convenient for the staff to operate and use, and improves the convenience of using the clamp.
