DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1: An automatic polishing device for lighting accessories, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8As shown, it includes a base 1, a support base 2, a grinding component 3, a transverse movement device, a lifting device, a rotating base 8, a supporting disc 9, a third motor 91, a positioning guide 10, a positioning rod 11 and an L-shaped limit rod 12. The support base 2 is installed on the upper right side of the base 1, and the grinding component 3 is installed on the upper part of the support base 2. The lighting accessories are finely processed by the grinding component 3, and the surface roughness is significantly reduced, becoming smoother and more delicate. A transverse movement device is provided on the support base 2, and the transverse movement device can move left and right on the support base 2. A lifting device is provided on the transverse movement device, and the lifting device can adjust the height of the grinding position. A rotating base 8 is rotatably provided on the lifting device, and a supporting disc 9 is rotatably provided on the rotating base 8. The bottom of the rotating base 8 A third motor 91 is provided at the bottom, and the top of the third motor 91 is connected to the supporting disc 9 through a coupling. A positioning guide frame 10 is rotatably provided at the bottom of the supporting disc 9. A guide groove is provided at a certain angle in the circumference of the supporting disc 9, and a total of eight guide grooves are provided. A positioning rod 11 is slidably installed in each guide groove, and the positioning guide frame 10 also has eight arc-shaped guide rail grooves, which correspond to the guide grooves, so that the positioning rod 11 is both inside the arc-shaped guide rail and inside the guide groove. An L-shaped limit rod 12 is slidably mounted on each positioning rod 11. When the positioning rod 11 moves inward along the arc-shaped guide rail and the guide groove at the same time, it drives the eight L-shaped limit rods 12 to retract inward, thereby clamping the lighting accessories in the middle.

[0025] like Figure 1 As shown, the transverse movement device includes a transverse movement seat 4, a screw rod 5 and a first motor 51. A guide rod is installed on the rear side of the base 1, and the transverse movement seat 4 is slidably installed on the guide rod. The screw rod 5 is rotatably provided on the front side of the base 1. The first motor 51 is installed on the left side of the base 1. The first motor 51 is connected to the left end screw rod 5 through a coupling. The front side of the transverse movement seat 4 is threadedly connected to the screw rod 5, and the rear side is slidably connected to the guide rod on the rear side of the base 1, ensuring that the lighting accessories are in contact with the polishing component 3 at an appropriate position, thereby automatically shifting.

[0026] like Figure 3 As shown, the lifting device includes a lifting seat 6, an electric push rod 7 and a guide rod 71. The electric push rod 7 is provided in the middle of the transverse movement seat 4. The top of the electric push rod 7 is connected to the lifting seat 6 through a push rod. The lifting seat 6 is rotatably connected to the rotating seat 8. The two sides of the bottom of the lifting seat 6 are connected with guide rods 71. The two guide rods 71 ​​are both slidably connected to the transverse movement seat 4, thereby ensuring that the lifting seat 6 is lifted vertically and is not easily skewed when it is lifted.

[0027] When it is necessary to grind and polish the lighting accessories, place the lighting accessories on the supporting disc 9 and start the third motor 91. The rotation of the third motor 91 causes the supporting disc 9 to rotate accordingly. Under the action of centrifugal force, the positioning rod 11 moves inward along the arc guide groove on the positioning guide frame 10. At the same time, the positioning rod 11 slides inward along the guide groove on the supporting disc 9, so that the L-shaped limit rod 12 connected to it is retracted inward, thereby clamping the lighting accessories on the supporting disc 9. After completing the clamping work, start the first motor 51 to drive the screw rod 5 to rotate, so that the transverse seat 4 moves along the thread of the screw rod 5 to the vicinity of the polishing assembly 3, and then start the electric push rod 7 to push the lifting seat 6 up and down to adjust the position of the lighting accessories. After the lighting accessories are positioned and clamped in multiple aspects and angles, start the polishing assembly 3 to polish them, thereby realizing automated polishing operations.

[0028] Example 2: Based on Example 1, Figure 3 As shown, a second motor 81 is also included. The second motor 81 is installed on the left side of the lifting seat 6. The output shaft of the second motor 81 passes through the left side of the lifting seat 6 and is connected to the rotating seat 8. Therefore, the second motor 81 can be used to fine-tune the tilt angle of the lighting accessories according to the polishing requirements to meet the polishing requirements of lighting accessories of different shapes and sizes.

[0029] like Figure 5 、 Figure 6 and Figure 7 As shown, it also includes a lifting crossbar 13, a return spring 14, a rotating guide rail seat 15 and a positioning guide rail 16. The positioning guide rail 16 is installed on the rotating seat 8, and the rotating guide rail seat 15 is rotatably installed in the middle of the top of the rotating seat 8. The positioning guide rail 16 is located above the rotating guide rail seat 15. The positioning guide rail 16 includes a cylindrical portion 161 and an extrusion portion 162. The cylindrical portion 161 is located inside the rotating guide rail seat 15, and the extrusion portion 162 is located at the top and outside of the rotating guide rail seat 15, and the outside portion is six downward protrusions. The rotating guide rail seat 15 is symmetrically provided with eight slide grooves, each of which has a sliding groove. A lifting cross bar 13 is provided, and each lifting cross bar 13 is slidably connected to the corresponding positioning bar 11, and the sliding type is located inside the L-shaped limit bar 12. A return spring 14 is provided on the positioning bar 11. The upper end of the return spring 14 is connected to the L-shaped limit bar 12, and the lower end is connected to the positioning bar 11. When the L-shaped limit bar 12 and the lifting cross bar 13 approach the polishing assembly 3, the lifting cross bar 13 moves downward along the trajectory of the protrusion of the extrusion part 162, thereby actively descending and avoiding the L-shaped limit bar 12 in the direction of the polishing belt, so that the lighting accessories are fully exposed to the polishing area for polishing operations.

[0030] like Figure 2As shown, it also includes a dust suction pump 17, a dust suction pipe 18 and a dust suction hood 19. The dust suction pump 17 is installed in the middle of the base 1, and the dust suction pipe 18 is connected to the right side of the dust suction pump 17. The dust suction hood 19 is connected to the dust suction pipe 18. The dust suction hood 19 is installed above the grinding component 3, so that the dust and debris generated during the grinding and polishing process can be quickly sucked in and collected through its powerful suction force, effectively avoiding the diffusion of dust and debris in the air, thereby reducing environmental pollution and health hazards to operators.

[0031] When it is necessary to adjust the tilt angle of the lighting accessory, the second motor 81 is started to drive the rotating seat 8 to rotate, so that the supporting disc 9 and the lighting accessory thereon are tilted, so that the lighting accessory clamped thereon can automatically contact the surface of the polishing belt at different angles and directions, and the lighting accessory is polished at various angles. During the polishing process, when the L-shaped limit rod 12 moves to the vicinity of the polishing assembly 3, the lifting cross bar 13 moves downward along the extrusion portion 162 of the positioning guide rail 16, driving the L-shaped limit rod 12 connected thereto to move downward, so that the lighting accessory at the blocking position of the L-shaped limit rod 12 can also be fully polished. When the L-shaped limit rod 12 is away from the polishing assembly 3, it is reset under the action of the reset spring 14 to continue clamping the lighting accessory. The dust suction pump 17 is started to suck the dust generated by polishing into the dust suction hood 19 and collect it through the dust suction pipe 18 to prevent the generation of a large amount of polishing dust during the polishing process. As the polishing progresses, the dust flies, and the dust diffuses and affects the operating environment.

[0032] The above-described embodiments merely represent preferred embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications, improvements, and substitutions without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
