Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliance metal plate processing, in particular to a grinding device used for electrical appliance metal plate processing. Background Art

[0002] In the production and processing of electrical appliances, some metal plates are often used. These metal plates need to be polished during the processing to remove surface burrs. This requires the use of a polishing device to polish the electrical metal plates. The polishing device for electrical metal plates is usually a grinder, which consists of a head and a body. When polishing, the worker holds the body of the grinder and then polishes the surface of the plate workpiece with the polishing disc set on the head of the grinder. During polishing, the polishing disc and the surface of the plate will produce very strong vibrations. This vibration is transmitted to the grinder, which will cause the worker's hand holding the grinder to vibrate strongly.

[0003] In the prior art, a patent application with application number CN201020612162.8, which was reviewed and published by the State Intellectual Property Office of China, discloses a utility model patent for a new type of grinder. The patent includes a grinder body, wherein the gripping portion of the grinder body is recessed inward, thereby forming a recessed portion, and an elastic rubber ring is embedded in the recessed portion; the elastic rubber ring is fitted over the gripping portion. The beneficial effect of the utility model is that when people use the utility model to grind hard objects in daily life, even if they use the grinder for a long time and the grinder body vibrates due to prolonged use, their hands will not feel numb.

[0004] However, when the new type of grinder in the prior art is used as a grinding device for processing metal plates of electrical appliances, the elastic rubber ring will gradually soften and fall off after long-term use, and it must be replaced in time. However, in the existing installation method of the elastic rubber ring, the inner ring side length of the elastic rubber ring is the same as the side length of the recessed portion of the body. As a result, when installing a new elastic rubber ring, the inner ring of the elastic rubber ring must first be expanded to the same size as the side length of the body, and then the elastic rubber ring is pushed into the recessed portion. During the pushing process, the elastic rubber ring is tightened against the surface of the body due to its own elasticity, resulting in a large friction between the two, making the replacement of the elastic rubber ring very laborious. Utility Model Content

[0005] The purpose of the present utility model is to provide a grinding device for processing metal plate parts of electrical appliances, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a grinding device for processing electrical metal plates, comprising: a grinder body and an elastic rubber ring, a fixed plate mounting groove being provided on the surface of the grinder body, one end of the fixed plate being movably inserted into the fixed plate mounting groove, the other end of the fixed plate extending from the fixed plate mounting groove, a side plate being fixed to the end of the fixed plate extending from the fixed plate mounting groove, and the elastic rubber ring being movably sleeved on the surfaces of the grinder body and the fixed plate.

[0007] Preferably, the elastic rubber ring is annular in structure, and the side length of the inner ring of the elastic rubber ring is equal to the side length of the polishing machine body.

[0018] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1 to 3 The utility model provides a technical solution: a grinding device for processing metal plates of electrical appliances, comprising: a grinder body 1 and an elastic rubber ring 4. A fixed plate mounting groove 2 is opened on the surface of the grinder body 1, one end of the fixed plate 3 is movably inserted in the fixed plate mounting groove 2, and the other end of the fixed plate 3 extends from the fixed plate mounting groove 2. A side plate 6 is fixed to the end of the fixed plate 3 extending from the fixed plate mounting groove 2, and the elastic rubber ring 4 is movably sleeved on the surface of the grinder body 1 and the fixed plate 3. The elastic rubber ring 4 has an annular structure, and the side length of the inner ring of the elastic rubber ring 4 is equal to the side length of the grinder body 1. Two groups of side plates 6 are provided, and the two groups of side plates 6 are symmetrically distributed about the elastic rubber ring 4. The ends of the two groups of side plates 6 close to each other respectively rest on the two end faces of the elastic rubber ring 4.

[0020] When the cam 6 is in the working state, the new one can be put on the new one by sliding the new one back to the workbench 1. When the cam 6 is in the working state, the new one can be put on the new one by sliding the new one back to the workbench 1.

[0021] Example 2: On the basis of Example 1, in order to realize the movable plug-in between the fixed plate 3 and the fixed plate mounting groove 2, the fixed plate mounting groove 2 is a rectangular groove structure, and the fixed plate 3 is a rectangular plate structure. Several groups of fixed plate springs 5 ​​are fixed between one end of the fixed plate 3 extending into the fixed plate mounting groove 2 and the inner wall of the groove of the fixed plate mounting groove 2, and the several groups of fixed plate springs 5 ​​are evenly distributed.

[0022] The fixing plate 3 is installed in the fixing plate mounting groove 2 by the fixing plate spring 5. When the fixing plate 3 moves deeper into the fixing plate mounting groove 2, the fixing plate spring 5 is compressed and does not hinder the movement of the fixing plate 3. When the fixing plate 3 returns to its original position, it only needs to release the fixing plate 3. The compressed fixing plate spring 5 automatically pushes the fixing plate 3 back to its original position without causing the fixing plate 3 to disengage from the fixing plate mounting groove 2, thereby realizing the movable plug-in between the fixing plate 3 and the fixing plate mounting groove 2.

[0023] Example 3: On the basis of Example 2, in order to prevent the fixing plate 3 from moving deep into the fixing plate mounting groove 2 when the grinder body 1 is in use, a limit plate mounting groove 7 is provided at one end of the two sets of side plates 6 that are away from each other. The limit plate mounting groove 7 is a rectangular groove structure, and one end of the limit plate 8 is movably inserted in the limit plate mounting groove 7. The limit plate 8 is a rectangular plate structure. The top end of the limit plate 8 extending out of the limit plate mounting groove 7 is against the bottom end of the grinder body 1. The end of the limit plate 8 extending into the limit plate mounting groove 7 is fixed with a limit spring 9, and the other end of the limit spring 9 is fixed to the inner wall of the groove of the limit plate mounting groove 7.

[0024] When the cam 7 is in operation, the cam 7 is pressed against the top of the workpiece 3 and the top of the workpiece 3 is pressed against the bottom of the workpiece 3.

[0025] In actual use, when replacing the elastic rubber ring 4 for the polishing machine body 1, the fixing plate 3 is moved to the depth of the fixing plate installation groove 2, and the side plate 6 follows the fixing plate 3 to move in the same direction. When the bottom end of the side plate 6 is flush with the bottom end of the polishing machine body 1, the old elastic rubber ring 4 can be removed and the new elastic rubber ring 4 can be put on the surface of the polishing machine body 1. After the new elastic rubber ring 4 is pushed into the position just below between the two sets of side plates 6, the fixing plate 3 is restored to its original position, and the two sets of side plates 6 move to the two ends of the elastic rubber ring 4, thereby aligning the elastic rubber ring. 4 is limited along the axis direction of the grinder body 1, and the replacement of the elastic rubber ring 4 can be completed. This makes it possible for the elastic rubber ring 4 to always maintain its original size without being stretched when replacing the elastic rubber ring 4, which also makes the friction between the elastic rubber ring 4 and the grinder body 1 not too large, making the replacement of the elastic rubber ring 4 time-saving and labor-saving; the fixing plate 3 is installed in the fixing plate installation groove 2 through the fixing plate spring 5. When the fixing plate 3 moves toward the depth of the fixing plate installation groove 2, the fixing plate spring 5 is compressed and does not hinder the movement of the fixing plate 3. When the plate 3 returns to its original position, it only needs to loosen the fixing plate 3. The compressed fixing plate spring 5 automatically pushes the fixing plate 3 back to its original position without causing the fixing plate 3 to disengage from the fixing plate mounting groove 2, thereby realizing the movable insertion between the fixing plate 3 and the fixing plate mounting groove 2. When the grinder body 1 is in use, one end of the limit plate 8 extends into the limit plate mounting groove 7, and the top end of the limit plate 8 extending out of the limit plate mounting groove 7 rests on the bottom end surface of the grinder body 1, so that even if the worker holds the elastic rubber ring 4 tightly, the fixing plate 3 will not move toward the fixing plate mounting groove 2 When the elastic rubber ring 4 needs to be replaced, it is only necessary to press the limit plate 8 toward the depth of the limit plate mounting groove 7 to make the limit plate 8 completely retracted into the limit plate mounting groove 7, and then the fixing plate 3 can be pushed into the fixing plate mounting groove 2, and when the limit plate 8 is completely retracted into the limit plate mounting groove 7, the limit spring 9 is compressed. When the elastic rubber ring 4 is replaced, the fixing plate 3 is released, and after the fixing plate spring 5 pushes the fixing plate 3 back to its original position, the limit spring 9 can also push the limit plate 8 back to its original position, thereby automatically completing the limiting of the fixing plate 3.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
