Description

Technical Field

[0001] This utility model relates to the field of workpiece surface polishing equipment, specifically to an automatic polishing equipment for efficient and fine polishing of high-gloss parts. Background Technology

[0002] In industrial production, polishing is necessary to reduce the surface roughness of workpieces and make them brighter and smoother. Currently, mechanical polishing is commonly used, typically employing oilstones, wool wheels, and sandpaper, and is primarily done manually. Workers place the rough workpiece on a rotating table for polishing. This method is slow, impacting work efficiency; the polishing debris easily flies everywhere, posing safety risks and being difficult to collect; furthermore, manual polishing with oilstones, wool wheels, and sandpaper can lead to incomplete polishing, resulting in a less smooth and glossy surface. It is also time-consuming, inefficient, and produces inconsistent polishing quality, making it unsuitable for mass production and increasing the risk of workplace injuries. While some existing automated polishing equipment can achieve automatic polishing of high-gloss parts, it lacks polishing wax compensation, especially in batch automated polishing where the polishing wax cannot be automatically compensated in a timely manner, resulting in a less refined high-gloss surface.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Please see Figure 1 As shown in the figure, an embodiment of this utility model proposes an automatic polishing device. This automatic polishing device includes a rough polishing fixture 2, a fine polishing fixture 3, and a polishing robot 4, all mounted on a T-shaped iron plate base 1. The polishing robot 4 has an iron base 41 at its arm end, and a part gripping fixture 5 is mounted on the iron base 41. Figure 3 , Figure 4 As shown, the fine polishing fixture 3 includes a fine polishing motor base 31, a fine polishing motor 32 fixed on the fine polishing motor base 31, a fine polishing wheel base 33 located at the upper end of the fine polishing motor base 31, and a fine polishing wheel 34 located on the fine polishing wheel base 33. The fine polishing motor 32 is connected to the fine polishing wheel 34 via a chain drive box 35. The fine polishing wheel base 33 is equipped with a polishing wax compensation device 36 and a first polishing slurry spray gun 37. A waste liquid discharge pipe 38 is connected to the bottom of the fine polishing wheel base 33. The polishing wax compensation device 36 can periodically compensate the polishing wax on the surface of the fine polishing wheel 34 during operation, maintaining a high degree of polishing performance on the polished surface of the fine polishing wheel 34. The first polishing slurry spray gun 37 sprays polishing slurry onto the polishing wheel 34 during the polishing operation. This reduces polishing dust generation and cools the rim surface of the polishing wheel 34, effectively preventing orange peel effect on the polished surface of the parts due to overheating. It also increases the lifespan of the polishing wheel 34 by 10-20%. It should be noted that in this embodiment of the invention, the polishing wax compensation device 36 uses solid polishing wax. This device is automatic, automatically compensating for polishing wax on the polishing wheel 34 during the early and middle stages of polishing wax application.

[0037] Furthermore, in a preferred embodiment of this utility model, such as Figure 5 , Figure 6 As shown, the polishing wax compensation device 36 includes a mounting bracket 361 fixed on the polishing wheel seat 33, a wax-adding slide 362 connected to the mounting bracket 361, a polishing wax clamping seat 364 slidably connected to the wax-adding slide 362, and polishing wax 365 disposed on the polishing wax clamping seat 364. The tail of the wax-adding slide 362 is equipped with a lead screw motor 367 for driving the polishing wax clamping seat 364 closer to the polishing wheel 34. By driving the polishing wax clamping seat 364 closer to the polishing wheel 34 via the lead screw motor 367, fully automatic compensation of the polishing wax 365 to the polishing wheel 34 can be achieved. Figure 5 As shown, the polishing wheel base 33 is provided with a pulley 351, the chain shaft transmission box 35 is provided with a driven pulley, the axle of the driven pulley is connected to the transmission shaft, the polishing wheel 34 is fixed on the transmission shaft by the cloth wheel pressing disc, and the motor shaft of the polishing motor 32 is connected to the pulley 351 for transmission.

[0038] Furthermore, in a preferred embodiment of this utility model, such as Figure 9 As shown, the waxing slide 362 is equipped with a lead screw 3671. The polishing wax holder 364 is tractably connected to the lead screw 3671 via a lead screw sleeve. The lead screw 3671 is connected to the motor shaft of the lead screw motor 367 via a coupling. To maintain the stability of the movement of the polishing wax holder 364, as follows...

[0040] Furthermore, in a preferred embodiment of this utility model, such as Figure 6 , Figure 7 As shown, the mounting bracket 361 is also equipped with a manual compensation mechanism 363 for driving the waxing slide 362 to slide back and forth on it. When the polishing wax 365 is consumed to a relatively short time, that is, when the polishing wax holder 364 is at its maximum forward stroke and the front end of the polishing wax 365 still cannot contact the surface of the polishing wheel 34, the manual compensation mechanism 363 can be used to continue to adjust the entire waxing slide 362 forward until the front end of the polishing wax 365 can contact the surface of the polishing wheel 34.

[0041] Specifically, such as Figure 8 As shown, the manual compensation mechanism 363 includes a reducer 3631 fixed on the mounting bracket 361, and a rack 3632 fixed on the lower surface of the waxing slide 362. The reducer 3631 meshes with the rack 3632 via gears, and the reducer 3631 is equipped with a manual adjustment wheel 36311. To make the waxing slide 362 more stable during sliding adjustment, such as... Figure 8As shown, the lower surface of the waxing slide 362 is provided with lower guide rods 3633 on both sides, and the mounting bracket 361 is provided with slide blocks on both sides, which are slidably engaged with the lower guide rods 3633. To prevent the polishing wax holder 364 from overtraveling during movement, as... Figure 9 As shown, the side of the waxing slide 362 is provided with a rear stroke sensor 368 and a front stroke sensor 369 for sensing the sliding stroke of the polishing wax holder 364.

[0042] Furthermore, in a preferred embodiment of this utility model, such as Figure 10 As shown, the part gripping fixture 5 includes a controllable demagnetizing strong magnetic base 51, a cover frame 52 connected to the strong magnetic base 51, a top plate 53 fixed to the cover frame 52, and an anti-overthrow plate 54 provided on the top plate 53. The anti-overthrow plate 54 has multiple contoured workpiece mounting openings 541, and the strong magnetic base 51 has a tensioner 55 for fixing and tightening the anti-overthrow plate 54. Specifically, as... Figures 11 to 16 As shown, the top plate 53 has multiple through mounting holes 531. The tensioner 55 includes a guide rod cylinder 551 fixed on the strong magnetic base 51, a chuck seat 552 fixed in the mounting holes 531, and a first chuck 554 and a second chuck 555 disposed in the chuck seat 552. The tail ends of the first chuck 554 and the second chuck 555 are respectively hinged to the guide rod head 553 of the guide rod cylinder 551 via a first torsion arm 556 and a second torsion arm 557 arranged obliquely on both sides. Figure 15 As shown, a connector 542 is formed on the lower surface of the anti-overshoot plate 54, and the head ends of the first clamp 554 and the second clamp 555 are clamped on the connector 542. Figure 15 As shown, to increase connection stability, in this embodiment of the invention, anti-slip teeth are provided on the opposing surfaces of the head ends of the first clamp 554 and the second clamp 555, and a toothed groove 5421 adapted to the anti-slip teeth is formed on the connector 542. Figure 10 As shown, a part 100 to be polished is fixed on the workpiece mounting opening 541 of the anti-over-polishing plate 54. To prevent the part 100 from being squeezed and deformed during polishing, the top plate 53 is provided with a corresponding contour pad 532 at the workpiece mounting opening 541 of the anti-over-polishing plate 54. The contour pad 532 provides support for the bottom of the part 100, preventing it from being squeezed and deformed during polishing. Figure 10 As shown, a conversion handle 511 for controlling the conversion of the direction of the internal magnetic force is provided on one side of the strong magnetic base 51. When switched to the magnetic state, the strong magnetic base 51 has a strong magnetic force and can be directly magnetically attracted to the iron base 41 at the end of the arm of the polishing robot 4.
