[0032] It should be noted that by providing the indicating block 12 on the slider, when the second cylinder 14 pushes the distance adjustment plate 4 to move, the indicating block 12 on the sliding block 11 will move together. The indicating block 12 indicates on the scale bar 13, and the scales of the indicating blocks 12 on both sides on the scale bar 13 are recorded, so that the positions of the distance adjustment plates 4 on both sides are kept consistent, realizing the centering and clamping of the workpiece and fixing the clamping position.

[0039] The detailed usage method and function of the above embodiments are as follows:

[0040] When the workpiece needs to be positioned and clamped, place the workpiece on the tray 3 inside the through hole 2, take out the clamping plate 8 suitable for clamping the workpiece. The clamping plate 8 and the quick-change plate 6 are fixedly connected. The quick-change plate 6 and the distance-adjusting plate 4 cooperate with each other. Align the holes on the quick-change plate 6 with the positioning pins 5 on the distance-adjusting plate 4 and insert them. Then use the locking screw 7 to lock the quick-change plate 6 and the distance-adjusting plate 4 together, thus realizing their fixed connection. Start the second cylinder 14. The telescopic rod of the second cylinder 14 is connected to the distance-adjusting plate 4. The bottom of the distance-adjusting plate 4 is connected with a sliding block 11 that cooperates with the guiding track 10. Push the two distance-adjusting plates 4 closer to each other. The side of the sliding block 11 is connected with an indicating block 12, and there is a scale bar 13 below the indicating block 12, which can be displayed on the scale bar 13, so as to know the displacement of the distance-adjusting plate 4. Start the first cylinder 9 to drive the tray 3 to change in height. After adjusting the workpiece to a suitable height, the clamping plates 8 on both sides clamp the workpiece in the center.

[0041] After the clamping of the workpiece is completed, when the positioned workpiece is no longer used, the existing device can be retained. Loosen the locking screw 7 to disassemble the distance-adjusting plate 4 and the quick-change plate 6. Thus, when clamping other workpieces next time, as long as the corresponding clamping plate 8 is produced, the positioning and clamping can be realized again.
