The present invention arranges a positioning mechanism on the inner side of the grinding box, and applies a thrust to the movable clamping plate through the rack so that the movable clamping plate is more stably clamped on the left end of the workpiece. When it needs to be taken out, the workpiece is only initially clamped and fixed by the elastic force of the spring at this time, so it can be quickly taken out, and the grinding process is sealed by the L-shaped plate to prevent waste chips from flying out, thereby achieving the beneficial effect of clamping the workpiece more quickly and stably and facilitating quick removal, while preventing waste chips from flying out.

[0038] Further, the fixing assembly includes four groups of top blocks 51, which are fixedly connected to the four corners of the bottom end of the support plate 50, and the bottom ends of the top blocks 51 abut against the top ends of one side of the lifting rod 57. The middle part of the lifting rod 57 is rotatably connected to the two groups of mounting brackets 56. The bottom ends of the two groups of mounting brackets 56 are both fixedly connected to the inner wall of the working groove 53. The working groove 53 is arranged inside the rectangular groove 52. The side of the lifting rod 57 away from the top block 51 is rotatably connected to the bottom end of the positioning block 58. The positioning block 58 is L-shaped. The positioning block 58 is slidably connected to the inside of the through groove 54. The through groove 54 is arranged at the top end of the device base 1. The bottom end of the through groove 54 is connected to the working groove 53. The through groove 54 and the positioning block 58 are both L-shaped.

[0039] In the grinding device of the prior art, it is inevitable to clamp and fix the two ends of the workpiece during the grinding process, and the existence of the clamping parts will hinder the normal grinding of the workpiece by the grinding head. Therefore, the two sides not clamped by the clamping parts are usually ground and polished first, and then the workpiece is removed and the ground two sides are fixed by the clamping parts, and finally the two sides not ground are ground and polished again. The operation process is cumbersome and the grinding efficiency is low. During operation, the structural design of the clamping mechanism realizes the function of moving the clamping part 36 and the fixing part 67 during the grinding and polishing process, ensuring that the clamping part 36 and the fixing part 67 do not move when clamping the workpiece body 20. The grinding of the grinding head 24 will be hindered. A motor is arranged inside the lifting frame 23 to drive the grinding head 24 to rotate at a high speed. By moving the hanger 21, the moving frame 22 and the lifting frame 23, the grinding head 24 can have a high degree of freedom, so as to grind and polish the outer surface of the workpiece body 20. When the workpiece body 20 is to be polished, the workpiece body 20 is first placed on the middle part of the device base 1, and then polished by the grinding head 24. When the grinding head 24 moves to the position of the clamping member 36, another set of clamping members 36 can be pulled outward at this time. The bottom ends of the two sets of clamping members 36 are connected to the first rack 39 through the connecting block 37. When the clamping member 36 is pulled outward, the first rack 39 will be driven to slide inside the movable groove 25. The side of the first rack 39 away from the connecting block 37 is meshed with the first gear 40. Therefore, pulling the first rack 39 will drive the first gear 40 to rotate. The first gear 40 and the second gear 42 are sleeved on the insert rod 44. The second gear 42 will rotate synchronously. During the rotation of the second gear 42, the two groups of second racks 43 meshed with the second gear 42 will move. At this time, when the clamping member 36 is pulled outward to cause the two groups of clamping members 36 to move away from each other, the two groups of second racks 43 drive the fixing members 67 connected to their top ends to approach each other, and the fixing members 67 will clamp and fix the left and right sides of the workpiece body 20. The workpiece body 20 is fixed to ensure that the workpiece body 20 does not move during the grinding and polishing process. Similarly, when the grinding head 24 moves to the position of the fixing part 67, the fixing part 67 can be separated from the workpiece body 20 by pulling the fixing part 67 on the other side or pushing the clamping part 36 inward, ensuring that the fixing part 67 does not hinder the movement of the grinding head 24. At this time, the workpiece body 20 is clamped and fixed by two groups of clamping parts 36, wherein two groups of protrusions 31 are fixed at the bottom end of the rotating disk 26. When the clamping part 36 is pulled outward, the arc spring 30 mounted on the arc rod 33 will be in a stretched state. The arc spring 30 can reset the clamping part 36 without pulling the clamping part 36.

[0040] The structural design of the locking mechanism realizes the function of fixing the first gear 40, so that when no workpiece is placed on the device base 1, the first gear 40 can remain fixed and not rotate, thereby preventing the clamping member 36 and the fixing member 67 on the device base 1 from moving on the movable groove 25 due to accidental contact. When the workpiece body 20 is placed on the support plate 50 in the middle of the device base 1, under the action of the workpiece body 20's own gravity, the four groups of support springs 49 fixed on the bottom end of the support plate 50 will be compressed, and the support plate 50 will move downward a certain distance. A fixing rod 46 is fixed on the bottom end of the support plate 50. When the fixing rod 46 moves downward, the two groups of blocks 47 fixed on the bottom end of the fixing rod 46 will slide in the slot 48 and finally separate from the slot 48. At this time, there is no abutment between the blocks 47 and the slot 48, and the insertion rod 44 can rotate normally.

[0041] Through the structural design of the fixing component, the function of assisting in fixing the four end corners of the workpiece body 20 during the grinding and polishing process of the workpiece body 20 is realized, so as to cooperate with the clamping member 36 and the fixing member 67 to fix the workpiece body 20, so that the workpiece body 20 can remain stable on the device base 1 without deviation. When the support plate 50 moves downward, the four groups of top blocks 51 fixed on the bottom end of the support plate 50 will push one side of the lifting rod 57. Since the middle part of the lifting rod 57 is rotatably connected to the mounting frame 56, one side of the lifting rod 57 descends and the other side rises. The side of the lifting rod 57 away from the top block 51 is rotatably connected to the bottom end of the positioning block 58. The lifting rod 57 can smoothly drive the positioning block 58 to move upward. At this time, the four end corners of the workpiece body 20 can be assisted by the positioning block 58 for fixing, ensuring that the workpiece body 20 will not deviate on the device base 1.

[0042] Further, the bottom end of the lifting frame 23 is rotatably connected to a driven gear 59, the driven gear 59 is meshed with a driving gear 62, the top end of the driving gear 62 is fixedly connected to the output shaft of the servo motor 61, the bottom end of the servo motor 61 is fixedly connected to the motor frame 60, the motor frame 60 is fixedly connected to the lifting frame 23, the bottom end of the driven gear 59 is fixedly connected to a fixing block 63, the bottom end of the fixing block 63 is fixedly connected to a connecting plate 64, the inner wall of the connecting plate 64 does not contact the grinding head 24;

[0043] During operation, the servo motor 61 is used to drive the active gear 62 to rotate, and the active gear 62 drives the fixed block 63 to rotate by meshing with the driven gear 59. The bottom end of the fixed block 63 is connected to the connecting plate 64, so the fixed block 63 will drive the connecting plate 64 to rotate, so that when the grinding head 24 is grinding the side of the workpiece body 20, the angle of the connecting plate 64 can be adjusted to ensure that the grinding head 24 can always maintain contact with the outer side of the workpiece body 20. The connecting plate 64 is sleeved on the outer side of the grinding head 24 and the inner wall does not contact the grinding head 24. Before the grinding head 24 moves to the clamping part 36 or the fixing part 67, the connecting plate 64 will push the clamping part 36 or the fixing part 67 open in advance, so there is no need to manually pull the clamping part 36 or the fixing part 67, which is more convenient.

[0044] Furthermore, the clamping member 36 and the fixing member 67 are provided with a plurality of plug holes 66, and guide rods 65 are inserted into the plug holes 66, and both sides of the guide rods 65 are fixedly connected to the inner wall of the movable groove 25;

[0045] During operation, a plurality of groups of insertion holes 66 are provided on the clamping member 36 and the fixing member 67. The guide rods 65 inserted into the insertion holes 66 are used to guide the clamping member 36 and the fixing member 67 when they move inside the movable groove 25, thereby ensuring that the clamping member 36 and the fixing member 67 can move stably without shaking.

[0046] Furthermore, the bottom end of the second rack 43 contacts the top end of the support frame 41, the top end of the support frame 41 is fixedly connected to the inner wall of the cavity 70, and the middle part of the support frame 41 is sleeved on the insertion rod 44;

[0047] During operation, the support frame 41 is located between the first gear 40 and the second gear 42, and is used to provide support for the bottom ends of the two sets of second racks 43, so that the second racks 43 can be more stable during movement.

[0048] Furthermore, a side of the arc rod 33 away from the protrusion 31 is fixedly connected to a limiting block 32, the limiting block 32 abuts against the arc block 29, and the radius of the limiting block 32 is greater than the radius of the arc rod 33;

[0049] During operation, the limit block 32 is designed to limit the maximum moving distance of the protrusion 31, so as to prevent the arc spring 30 from being over-stretched and damaged due to excessive rotation angle of the rotating disk 26. Example

[0050] See also Figure 3 , Figure 4 and Fig. 9As shown, as another embodiment of the present invention, the clamping member 36 and the fixing member 67 are provided with a groove 68 on one side close to the workpiece body 20, and a cushion block 69 is fixedly connected to the groove 68, and the cushion block 69 is made of rubber material;

[0051] During operation, the size of the pad 69 matches the groove 68. The pad 69 is used to increase the friction between the clamping member 36 and the fixing member 67 and the workpiece body 20, so that the clamping member 36 and the fixing member 67 have a better clamping effect on the workpiece body 20.

[0052] The inner wall of the rectangular groove 52 is fixedly connected with a fixing sleeve 55, and the fixing sleeve 55 is sleeved on the outer side of the top end of the fixing rod 46, and the top end of the fixing sleeve 55 abuts against the bottom end of the support plate 50;

[0053] During operation, the fixed sleeve 55 is sleeved on the outside of the fixed rod 46 to protect the fixed rod 46, and the top end of the fixed sleeve 55 also abuts against the bottom end of the support plate 50 to support the bottom end of the support plate 50, while also limiting the maximum distance that the support plate 50 can move downward in the rectangular groove 52, so that the bottom end of the workpiece body 20 can remain level with the top end of the device base 1.
