Description

TECHNICAL FIELD

[0001] The utility model relates to the field of processing equipment, especially relates to a polishing device for microcrystalline glass finishing. BACKGROUND

[0002] Microcrystalline glass is mainly composed of base glass and crystal phase. The base glass is usually silicate glass containing various metal oxides, and the microcrystalline glass has good optical transparency and gloss. It can transmit visible light and part of infrared rays, and its surface can be processed to a very smooth state, with a glass-like gloss, which can be used to make optical lenses, decorative panels, etc.

[0003] When the polishing tool contacts the surface of the microcrystalline glass and a certain pressure is applied, the microcrystalline glass may slide or rotate on the workbench, causing the polishing position to deviate, resulting in uneven surface that should have been polished flat. The waviness of the polished surface will cause the smoothness of the microcrystalline glass to decrease and the surface roughness to increase. Most polishing devices are fixed in position when polishing the microcrystalline glass, and the orientation of the polishing device cannot be adjusted. For thicker plates, the surface may not be able to be contacted for polishing, while for thinner plates, the polishing head may be too deeply inserted, damaging the microcrystalline glass or the polishing head itself, resulting in ineffective polishing of microcrystalline glass of different height specifications, reducing work efficiency, and requiring more manual operation and time to complete the same polishing task.

[0039] When the top output end of the bidirectional motor 203 is turned on, the first rotating shaft 204 starts to rotate. Since the first rotating shaft 204 penetrates the joint block 205 and makes the joint block 205 rotate, the supporting rod 206 on the bottom wall of the joint block 205 is fixedly connected with the first sliding block 207, and the first sliding block 207 slides in the limiting groove 202 on the top wall of the shell 201, with the rotation of the joint block 205, the supporting rod 206 drives the first sliding block 207 to slide inwards in the limiting groove 202, so that the clamping block 208 fixedly connected with the top of the first sliding block 207 moves inwards synchronously. Thus, the four clamping blocks 208 can shrink from the periphery to the center, tightly clamping the microcrystalline glass.

[0040] When the top output end of the bidirectional motor 203 is reversed, the first rotating shaft 204 reverses rotation, driving the joint block 205 to reverse rotation. At this time, the supporting rod 206 drives the first sliding block 207 to slide outwards in the limiting groove 202, and the clamping block 208 expands outwards synchronously, loosening the microcrystalline glass, and taking out the microcrystalline glass.

[0041] In addition, by fixing the bottom wall of the shell 201 on the outside of the second rotating shaft 209 of the bottom output end of the bidirectional motor 203, when the bottom end of the second rotating shaft 209 rotates on the bottom wall of the dustproof box 1, the clamping mechanism 2 can be driven to rotate flexibly inside the dustproof box 1, so as to adjust the direction of the microcrystalline glass, and facilitate the processing of different parts of the microcrystalline glass by the polishing tool.

[0042] The first driving motor 8 serves as a power source, and after being started, the output end drives the rotator 11 to rotate. The rotator 11 is fixedly connected with the left end of the screw rod 12, so as to transmit the rotating power to the screw rod 12, and make the screw rod 12 rotate in the supporting frame 9. When the screw rod 12 rotates, the second sleeve 15 moves axially along the screw rod 12. In order to ensure the stability and directionality of the movement of the second sleeve 15, and drive the second sleeve 15 to slide left and right on the outside of the screw rod 12, the second sliding block 16 fixedly connected with the outside of the second sleeve 15 is connected with the outside of the supporting rod 14 through the inside of the front and rear two sides, so as to provide a stable effect for the second sliding block 16 when the second sleeve 15 drives the second sliding block 16 to slide.

[0043] The second slider 16 is fixedly connected with a connecting plate 17 at the bottom, and an electric push rod 18 is fixed at the bottom of the connecting plate 17. When the height of the polishing disc 27 needs to be adjusted, the electric push rod 18 works. When the electric push rod 18 is elongated, the telescopic rod 19 is extended downward, and the components connected at the bottom of the telescopic rod 19 are lowered together. When the electric push rod 18 is shortened, the telescopic rod 19 is retracted upward, and the related components are raised. The connecting rod 20 is lifted together with the telescopic rod 19. The connecting rod 20 is fixedly connected with a rack 21 at the top outside. The telescopic rod 19 is also fixedly connected with a first fixing ring 22 at the bottom outside. The second drive motor 24 is fixed outside through the second fixing ring 23 at the back of the first fixing ring 22.

[0044] When the microcrystalline glass needs to be polished, the second drive motor 24 is started. The connecting shaft 25 on the output end of the second drive motor 24 drives the gear 26 to rotate. Due to the meshing action of the gear 26 and the rack 21, although the rack 21 itself does not rotate in a whole circle, it can transmit power to the polishing disc 27 through the connecting rod 20. The connecting rod 20 drives the polishing disc 27 to rotate around its own axis, so that the abrasive on the polishing disc 27 contacts and rubs the surface of the microcrystalline glass, thereby realizing the polishing of the microcrystalline glass.

It should be understood by those skilled in the art that the present application is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
