Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a grinding ring polishing machine. Background Art

[0002] Polishing machines are also called grinders and are often used for mechanical grinding, polishing and waxing. The working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the combined effect of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed.

[0003] According to the existing Chinese patent CN 218137244 U, a grinding ring grinding disc comprises a circular grinding disc body and a spiral protrusion arranged on the upper surface of the grinding disc body, wherein the protrusion is concentric with the grinding disc body, and the cross section of the protrusion gradually narrows from bottom to top, and the top surface of the protrusion on the upper surface of the grinding disc body is narrowed. After the top surface of the protrusion is narrowed, the abrasive of the grinding liquid can no longer be attached, thus avoiding the problem of scratches on the grinding ring caused by the abrasive attached to the top surface of the protrusion. A grinding ring polishing machine is also provided.

[0004] As shown in the above-mentioned prior art, the existing grinding ring polishing machine does not have a device for cleaning the grinding disc. However, in the actual grinding ring polishing work, the grinding disc needs to be cleaned manually before work. Cleaning the grinding disc can not only prevent grinding liquid contamination, but also prevent scratches by foreign objects.

[0005] Therefore, it is necessary to provide a grinding ring polishing machine to solve the above-mentioned technical problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides two technical solutions:

[0026] Figure 1 to Figure 2 The first embodiment is shown: a grinding ring polishing machine includes a grinder body 1, a grinding disc 2 is rotatably installed above the grinder body 1, a brush 3 for brushing the grinding disc 2 is installed above the grinder body 1, a moving component for driving the brush 3 to approach and move away from the grinding disc 2 is installed above the grinder body 1, a compensation component is slidably connected above the grinder body 1 and can make the brush 3 descend to compensate for the loss of the brush 3, and the brush 3 is clamped to the compensation component by a snap assembly.

[0027] The moving assembly includes a motor 4 fixed above the grinder body 1, a first screw 5 is rotatably connected to the grinder body 1 through a bearing, the output end of the motor 4 is fixed to one end of the first screw 5, and the outer wall of the first screw 5 is threadedly connected to the compensation assembly through a first threaded hole.

[0028] This application arranges a brush 3 and a moving component above the grinder body 1, so that before using the grinding ring polisher, the moving component can be driven to make the brush 3 close to the grinding disc 2, and the grinding disc 2 can be driven to rotate so that the brush 3 can brush the grinding disc 2, thereby preventing contamination of the grinding fluid and scratches by foreign objects during the grinding work, and is practical.

[0029] Figure 3 to Figure 4A second embodiment is shown, and its main difference from the first embodiment is that the compensation assembly includes a movable frame 6 threadedly connected to the outer wall of the first screw 5, the bottom of the movable frame 6 is slidingly connected to the grinder body 1, the inner wall of the movable frame 6 is rotatably connected to the second screw 7 through a bearing, the top of the second screw 7 passes through the movable frame 6 and is fixed with a handwheel 8, and the outer wall of the second screw 7 is threadedly connected to the snap assembly through a second threaded hole.

[0030] The snap assembly includes a plug-in block 9 threadedly connected to the outer wall of the second screw rod 7, the plug-in block 9 is slidably connected to the inner wall of the movable frame 6, the plug-in block 9 is plugged into the brush 3 through a socket on the side close to the grinding disc 2, the outer edge of the socket is chamfered, a slot 10 is provided on the top of the brush 3 close to the plug-in block 9, a block 11 is slidably connected to the top of the plug-in block 9 through a sliding hole, a pulling groove 13 is provided on the upper end of the block 11, four springs 12 are symmetrically fixedly connected to the top of the inner wall of the plug-in block 9, and the end of the spring 12 facing away from the plug-in block 9 is fixed to the block 11.

[0031] This application sets a compensation component so that the brush 3 will be worn out after long-term use, resulting in poor brushing effect. At this time, the brush 3 can be lowered close to the grinding disc 2 by turning the hand wheel 8 to compensate for the wear of the brush 3, which is economically beneficial. The buckle component is set so that the brush 3 can be replaced conveniently and quickly, thereby improving work efficiency.

[0032] Working principle:

[0033] Before using the grinding ring polisher for polishing, the grinding disc 2 needs to be brushed to remove foreign matter and grinding liquid residue on the surface of the grinding disc 2. At this time, the driving motor 4 rotates the first screw 5 to drive the moving frame 6 to move on the grinder body 1 close to the grinding disc 2, and the brush 3 moves to the top of the grinding disc 2. After the grinding disc 2 rotates, the cleaning liquid is dripped, and the brush 3 brushes and cleans the grinding disc 2 as it rotates.

[0034] The brush 3 is prone to wear when rubbing and cleaning on the surface of the grinding disc 2. A compensation component is used to compensate for the wear. The handwheel 8 is turned to rotate the second screw 7, driving the plug-in block 9 to descend on the outer wall of the second screw 7. The brush 3 then descends to compensate for the wear. The handwheel 8 can be stopped when the brush 3 just touches the surface of the grinding disc 2.

[0035] When the brush 3 has a poor brushing effect and cannot meet the brushing needs by using a compensation component, the brush 3 can be replaced; use the lifting groove 13 to pull the block 11 upward, and the four springs 12 are compressed accordingly. When the block 11 completely leaves the slot 10, the brush 3 can be taken out along the socket; insert the new brush 3 into the plug-in block 9 through the socket, and the end of the brush 3 close to the plug-in block 9 squeezes the inclined surface of the block 11, so that the block 11 moves up and compresses the spring 12 until the brush 3 is completely pushed in, the spring 12 rebounds, and the block 11 is then inserted into the slot 10 to fix the brush 3, and the replacement of the brush 3 is completed.
