[0026] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0028] Referring to Figure 1 , the present utility model provides a grinding device for a crystal grinding and polishing machine, including a machine base 1, on which a plurality of connecting seats 11 are arranged at intervals; a grinding and polishing mechanism 2 is provided on the machine base 1, and the grinding and polishing mechanism 2 includes a grinding and polishing disk 21, which can be adjusted in position relative to the machine base 1 to contact the blank for grinding; a flipping seat 3 is arranged between two adjacent connecting seats 11, the flipping seat 3 is rotatably connected to the connecting seat 11, and a flipping driving mechanism 31 is arranged between the flipping seat 3 and the machine base 1, and the flipping driving mechanism 31 is used to drive the flipping of the flipping seat 3. An aluminum row frame 4 is movably connected to the flipping seat 3, and a plurality of bushings 41 are arranged on the aluminum row frame 4, and the bushings 41 are used to clamp the crystal blank. The rotation of the flipping seat 3 is for multi-directional grinding of the surface of the blank.

[0029] An aluminum row moving mechanism 42 is provided between the flipping seat 3 and the aluminum row frame 4 of the present device. The aluminum row moving mechanism 42 can drive the aluminum row frame 4 to move, so as to move the clamping end of the bushing 41 to the center of the rotation axis 15 of the flipping seat 3 and the connecting seat 11, so that the center lines of the crystal blanks clamped by the bushings 41 are all located on this rotation axis 15. Since the connecting seat 11 also rotates around this axis, in the present device, when the connecting seat 11 rotates, the center line of the crystal blank always coincides with this rotation axis, so the relative distance between the crystal blank and the grinding and polishing disk 21 also remains fixed, ensuring the consistency of the ground surface of the blank material.

[0030] At the same time, in order to improve the grinding efficiency of the blank, a bushing 41 rotation mechanism is also provided on the aluminum row frame 4. The bushing 41 rotation mechanism can drive the bushing 41 to rotate. The rotation of the bushing 41 is synchronized with the rotation of the flipping seat 3, so as to comprehensively grind the surface of the blank as quickly as possible.

[0031] Embodiment 1

[0032] Referring to Figure 2, in this embodiment, the aluminum row moving mechanism 42 includes a guide rail 421 fixed on the flipping seat 3. A slider 422 and a driving lead screw nut 423 are fixed on the aluminum row rack 4. The slider 422 is slidably connected to the guide rail 421. A driving motor 32 is provided on one side of the flipping seat 3. A driving lead screw 321 is connected to the driving motor 32. The driving lead screw nut 423 is sleeved on the driving lead screw 321. The driving motor 32 drives the driving lead screw 321 to rotate, thereby driving the driving lead screw nut 423 to move up and down, and driving the up and down movement of the aluminum row rack 4 through the driving lead screw nut 423 to adjust the position of the clamping end of the bushing 41. The cooperation between the slider 422 and the guide rail 421 can ensure the stability of the aluminum row rack 4 during the moving process.

[0033] Refer to Figure 2 , a plurality of first relief grooves 33 and second relief grooves 34 are provided on the flipping seat 3. The guide rail 421 is fixed in the first relief groove 33. The driving lead screw 321 and the driving lead screw nut 423 are arranged in the second relief groove 34. The setting of the relief grooves can increase the space utilization rate inside the flipping seat 3 and avoid the waste of space caused by too many parts protruding. A transmission wheel 322 is provided at the end of the driving lead screw 321. A driving wheel 323 is provided on the driving motor 32. A synchronous belt 324 is provided between the driving wheel 323 and the transmission wheel 322. The driving motor 32 drives the operation of the driving lead screw 321 through the synchronous belt 324.

[0034] Embodiment 2

[0035] In this embodiment, the aluminum row moving mechanism 42 includes a plurality of rotating blocks 424. The rotating blocks 424 are fixed on the flipping seat 3. Refer to Figure 3 , the aluminum row rack 4 is rotatably connected to the rotating blocks 424. The rotatable connection position is preferably arranged on the side of the rotating blocks 424. A driving cylinder 425 with a telescopic shaft 14 is provided on the flipping seat 3. The end of the telescopic shaft 14 is hinged to the aluminum row rack 4. The driving cylinder 425 pulls the aluminum row rack 4 to rotate around the rotating blocks 424 as the axis through the telescopic movement of the telescopic shaft 14, thereby adjusting the position of the clamping end of the bushing 41.

[0036] The main difference between Embodiment 1 and Embodiment 2 lies in the specific structure of the aluminum row moving mechanism 42. The two embodiments adjust the position of the aluminum row rack 4 in two forms of vertical movement and rotation respectively, so as to adjust the clamping end of the bushing 41 to the center of the rotating shaft 15 of the flipping seat 3 and the connecting seat 11. While solving the problem of poor consistency of blank grinding in the background technology, more choices are provided for users, so as to better meet the needs of different actual application scenarios.

[0037] The following described other structures are common devices for the two embodiments.

[0038] Refer to Figure 1 , the flipping drive mechanism 31 includes an adjusting screw nut 311 rotatably connected to the side of the flipping seat 3, and an adjusting motor 312 rotatably connected to the machine base 1. An adjusting screw 313 is provided on the adjusting motor 312. The adjusting screw nut 311 is sleeved on the adjusting screw 313. The adjusting motor 312 drives the adjusting screw 313 to rotate, so as to change the position of the adjusting screw nut 311. During the adjustment process, the adjusting screw nut 311 rotates relative to the flipping seat 3, and at the same time, the flipping seat 3 is pulled to rotate, so as to change the contact surface between the blank in the bushing 41 and the grinding disc. This structure also has the effect of high adjustment accuracy. For example, there is a gap between the adjusting screw 313 and the adjusting screw nut 311. Since this gap is far from the rotation axis line, during the rotation of the flipping seat, the influence of the gap on the position of the rotation axis will be reduced by a multiple, so as to ensure the stable position of the blank located on the rotation axis line during the rotation process, and further ensure the consistency of the grinding effect.

[0039] Refer to Figure 1 , Figure 2 , an adjusting frame 35 is fixed on the side of the flipping seat 3. The adjusting screw nut 311 is rotatably connected in the adjusting frame 35. The adjusting frame 35 can protect the adjusting screw nut 311. Spaced connection pieces 12 are provided on the machine base 1. The adjusting motor 312 is rotatably connected between the connection pieces 12.

[0040] Refer to Figure 2 , the bushing 41 rotation mechanism includes a driving worm 431. A through hole is provided in the aluminum row frame 4. The driving worm 431 is rotatably connected in the through hole. A turbine is provided at the end of the bushing 41. The turbine is not shown in the specification drawings, and its specific structure is the same as that of the traditional turbine and worm. The turbine meshes with the driving worm 431. A transfer shaft 36 is rotatably connected to the flipping seat 3. The transfer shaft 36 is inserted and fixed to the end of the driving worm 431. A rotating motor 37 is also fixed on the flipping seat 3. The rotating motor 37 is used to drive the transfer shaft 36 to rotate.

[0041] Refer to Figure 4, the position adjustment of the grinding and polishing disc 21 can be carried out vertically. The specific structure is that a relief hole 13 is provided in the machine base 1. A rotating shaft 22 is provided in the relief hole 13 of the machine base 1. The rotating shaft 22 is rotated by a motor and a synchronous belt. The grinding and polishing disc 21 is fixed to the top of the rotating shaft 22. A liftable bearing plate 23 is provided at the bottom of the rotating shaft 22. The lifting of the bearing plate 23 can be achieved through a lead screw nut and a lead screw. The bearing plate 23 and the lead screw nut maintain a fixed relative vertical position. The up and down movement of the bearing plate is driven by the rotation of the lead screw. According to different use environments, the grinding and polishing disc 21 can also be adjusted horizontally. The structure of the horizontal adjustment will not be elaborated here.

[0042] Refer to Figure 5 , multiple groups of this grinding mechanism can be set in the crystal grinding and polishing machine. Each group of grinding mechanisms is arranged horizontally. A slide rail is provided at the top. The aluminum row frame 4 can flow between different grinding mechanisms under the action of the clamping mechanism on the slide rail, which can speed up and also obtain better grinding effects.

[0043] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
