[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0026] like Figure 1 - Figure 5 As shown, this application provides a cleaning and polishing device for grooved bushings, including a polishing device 1 and a polishing belt 101 disposed on the polishing device 1, with polishing tables 2 disposed on both sides of the polishing device 1; and also includes;
[0027] Specifically, such as Figure 2 As shown, a limiting component 3 is provided on the top of the grinding table 2. The limiting component 3 is used to limit the bushing. The limiting component 3 includes a roller shaft 301, which is provided on the top of the grinding table 2. A limiting plate 303 is snapped onto the top of the grinding table 2. By providing the limiting component 3 on the top of the grinding table 2, and by sequentially installing the roller shaft 301 and the limiting plate 303 on the limiting component 3 on the top of the grinding table 2, the bushing can be limited, thereby improving the stability of the bushing during grinding.
[0028] Specifically, such as Figure 3As shown, a support rod 302 is rotatably connected to the bottom side of the roller shaft 301. A groove 3021 is provided on the top of the grinding table 2. The support rod 302 is slidably connected inside the groove 3021. A fixing member 304 is slidably connected inside the grinding table 2. A fixing hole 3041 is provided on the inner wall of the groove 3021. The fixing member 304 abuts against the side wall of the support rod 302. The fixing member 304 is inserted into the fixing hole 3041. By inserting the support rod 302 into the inner wall of the groove 3021 and rotating the rotating rod 307 and the gear 306, the two sets of toothed plates 305 and the fixing member 304 can be moved to both sides. At this time, the fixing member 304 will be inserted into the fixing hole 3041 to fix the two sets of support rods 302.
[0029] Specifically, such as Figure 4 As shown, a rotating rod 307 is rotatably connected to the side wall of the grinding table 2, and a gear 306 is fixedly connected to the end of the rotating rod 307. The gear 306 is rotatably connected inside the grinding table 2. A toothed plate 305 is fixedly connected to the side wall of the fixing member 304. The toothed plate 305 and the gear 306 mesh with each other. By rotating the rotating rod 307 and the gear 306 in the opposite direction, the two sets of toothed plates 305 and the fixing member 304 can be driven to move and retract inward. At this time, the roller shaft 301 can be removed from the grinding table 2, and the plate-shaped workpiece can be placed on the top of the grinding table 2 for grinding, which improves its applicability.
[0030] The two sides of the grinding table 2 are fixedly connected with baffles 308. The baffles 308 can limit the debris after grinding, thus preventing the debris from flying and injuring people.
[0031] The top of the grinding table 2 has multiple sets of slots 3031. A limiting plate 303 is inserted into the slots 3031. By inserting the limiting plate 303 into the slots 3031 on both sides of the bushing, the bushing can be limited, preventing the bushing from shaking randomly during the grinding process and improving its processing stability.
[0032] Specifically, such as Figure 5 As shown, an adjustment component 4 is provided between the grinding equipment 1 and the grinding table 2. The adjustment component 4 is used to move the grinding table 2. The adjustment component 4 includes a moving plate 402, which is set on the side wall of the grinding table 2. A lead screw 403 is threadedly connected to the top of the moving plate 402. By setting the adjustment component 4 between the grinding equipment 1 and the grinding table 2, the moving plate 402 and the grinding table 2 can be moved up and down by rotating the lead screw 403 on the adjustment component 4. This facilitates the adjustment of the distance between the grinding table 2 and the grinding belt 101 according to different sizes of bushings, thus improving its applicability.
[0033] A connector 401 is fixedly connected to the side wall of the grinding table 2. An adjustment groove 4021 is provided on the side wall of the grinding equipment 1. The connector 401 is slidably connected inside the adjustment groove 4021. A moving plate 402 is fixedly connected to the side wall of the connector 401 and slidably connected inside the adjustment groove 4021. A lead screw 403 is rotatably connected inside the adjustment groove 4021. By setting a motor and other driving components inside the grinding equipment 1 and fixing the output shaft of the motor to the lead screw 403, the motor drives the lead screw 403 to rotate. At the same time, the lead screw 403 can drive the moving plate 402 and the grinding table 2 to move up and down.
[0034] For details on the specific functions and operation of the grinding equipment 1 and the grinding belt 101, please refer to the double-head polishing and grinding machine with model number PG40.
[0035] The specific solution is as follows: First, the support rod 302 is inserted into the inner wall of the slide groove 3021, and the rotating rod 307 is rotated to move the two sets of fixing parts 304 and the two sets of support rods 302 to be fixed by clamping. Then, the bushing is placed between the two sets of roller shafts 301. Then, the limiting plate 303 is inserted into the slots 3031 on both sides of the bushing to limit the bushing. Next, the motor drives the lead screw 403 to rotate. At the same time, the lead screw 403 can drive the moving plate 402 and the grinding table 2 to move upward until the bushing contacts the grinding belt 101. Finally, the grinding belt 101 on the grinding equipment 1 can be driven to grind the bushing.
