[0025] Furthermore, an annular groove is provided in the middle of the outer side of the mounting block 18, and the rotating plate 13 is sleeved on the outer side of the annular groove, so that the rotating plate 13 can be limited so that it can only rotate in the annular groove.

[0026] Furthermore, guide grooves are provided at both ends of the inner side of the positioning groove 14 , and guide blocks matching the guide grooves are provided at both ends of the clamping block 10 . When the clamping block 10 moves, the guide blocks can be driven to slide along the guide grooves, thereby improving the activity stability of the clamping block 10 .

[0027] Furthermore, an arc-shaped rubber pad is provided in the middle of the bottom of the clamping block 10 to improve the buffering performance of the clamping block 10 and enhance the clamping effect on the shaft rod.

[0028] Working principle: When the device processes the throttle shaft, the throttle shaft can be passed through the positioning groove 14 and then inserted into the card slot A6. Then, the limit plate 4 can be slid to a suitable position to fix the shaft rod through the guidance of the guide rod 2. After the limit plate 4 is moved, the electric push rod B11 can be started to run, and the clamping block 10 can be driven by the electric push rod B11 to move down to clamp the shaft rod. At this time, the exposed end of the shaft rod can be processed. After the end of one side is processed, the limit plate 4 can be slid to drive the shaft rod to be pulled out of the card slot A6, and then the limit plate 4 can be rotated 180 degrees to exchange the positions of the two ends, and then inserted into the card slot A6 to process the other end.

[0029] When processing the rod body of the throttle shaft, after the clamping block 10 fixes the shaft rod, the plug rod 17 can be pulled out of the slot 19 by pulling the ball to overcome the elastic force of the spring 16, thereby releasing the fixation of the rotating plate 13, and then the rotating plate 13 is rotated 180 degrees to align the slot B12 with the slot A6. At this time, the plug rod 17 is loosened, and the elastic force of the spring 16 can be used to push the plug rod 17 into another set of slots 19 to fix the rotating plate 13. Then the electric push rod A7 is started, and the push plate 8 can be driven by the electric push rod A7 to move the connecting rod 9 to one side, thereby driving the slot B12 to clamp the shaft rod from the other side of the shaft rod. At this time, the shaft rod can be fixed in four directions: up, down, left, and right, thereby improving the fixing stability.
