[0032] The separation assembly includes two push plates 32, two flip plates 33 and a top plate 34. The two push plates 32 are symmetrically slidably installed at the two ends inside the connecting block 23, and the two flip plates 33 are symmetrically rotatably installed at the two ends inside the connecting block 23. A top rod 35 is fixedly installed in the middle of the bottom end of the top plate 34, and the top rod 35 is slidably connected to the connecting block 23.

[0033] Protection pads 37 are fixedly installed on the opposite sides of each adjacent fixed clamping plate 12 and movable clamping plate 13. Strip grooves 38 are opened at both ends of the multiple adjustment plates 15, and the multiple L-shaped support plates 22 respectively cooperate with their corresponding strip grooves 38.

[0034] Working principle: When in use, when the crystal rods to be polished are cylindrical, multiple cylindrical crystal rods can be directly placed on top of two adjacent support rollers 10, and then the cylinder 1 7 on the top of the multiple polishing heads 5 is activated to push the multiple polishing heads 5 down, and then cooperate with multiple electric slides 3 to polish multiple cylindrical crystal rods;

[0035] When the crystal rod to be polished is rectangular, the movement process of one of the adjustment mechanisms 1 and the corresponding switching mechanism is as follows: start the cylinder 2 14, push the adjustment plate 15 to move upward, the two transmission rods 16 move upward synchronously, and drive the two ends of the two transmission rods 16 to slide in their respective corresponding adjustment grooves 17. At this time, the corresponding support frame 1 8 and support frame 2 9 slide away from each other along their respective corresponding guide rods 18. At this time, the distance between the two support rollers 10 is also adjusted, so that it is suitable for cylindrical crystal rods of different specifications and sizes, which improves the applicability of the device. When the adjustment plate 15 moves to a certain height, the adjustment plate 15 drives the plug-in block 24 to extend into the inside of the corresponding plug-in groove 25. The two card plates 31 are first moved inwardly close to each other by the action of the connecting block 23. The two transmission plates 30 operate synchronously and push the connecting plate 27 to move downward. The connecting plate 27 drives the push rod 28 to move downward. The push rod 28 squeezes the spring 1 29, and the two card plates 31 are retracted into the inside of the plug-in block 24. The plug-in block 24 moves upward. When the top of the plug-in block 24 contacts the plug-in slot 25, the connecting block 23 and the plug-in block 24 move upward synchronously, thereby driving the fixing seat 11 to move upward. The fixing seat 11 drives the two guide rods 3 21 to move synchronously. Under the action of the two guide rods 3 21, the fixing seat 11 moves upward steadily. As the connecting block 23 moves, the two push plates 32 gradually move away from the two L-shaped support plates 22. Under the action of the two springs 2 36, the top plate 34 drives the top rod 35 to move upward. , the two flip plates 33 flip accordingly and act on the two push plates 32. The two push plates 32 move downward, and the two clamping plates 31 at this time also move away from each other and outward under the action of the spring 1 29, and are respectively clamped into the two clamping grooves 26, thereby achieving the fixation between the fixed seat 11 and the adjustment plate 15. When the adjustment plate 15 rises to the top, the support frame 1 8 and the support frame 2 9 also move to the end. The movement process of the remaining multiple adjustment mechanisms 2 and the corresponding switching mechanisms is the same as described above;

[0036] At this point, the rectangular crystal ingot can be placed between the fixed clamping plate 12 and the movable clamping plate 13. By activating the air cylinder 3 20, the movable clamping plate 13 is pushed to slide along the two guide rods 2 19. The movable clamping plate 13 cooperates with the fixed clamping plate 12 to clamp and fix the side of the rectangular crystal ingot. Then, the corresponding electric slide 3 is activated to move the grinding head 1 4 to the top of the rectangular crystal ingot. The air cylinder 1 7 on the top of the grinding head 1 4 is activated, and the electric slide 3 is used to grind the rectangular crystal ingot.

[0037] This device can place rectangular crystal rods and cylindrical crystal rods on the top of the grinding platform 1 at the same time for grinding, achieving the effect of multi-station parallel grinding, solving the problem of only one type of fixture in the prior art. Moreover, through the provided adjustment mechanism 1 and switching mechanism, the fixture can be quickly switched, and the switching time is short, which is conducive to improving the work efficiency of crystal rod grinding.
