Description

Technical Field

[0001] The utility model relates to the technical field of abrasive tool manufacturing, in particular to a grinding wheel polishing device. Background Art

[0002] Grinding wheels are generally melted to obtain a rough blank of a predetermined shape, and then a sawing machine is used to cut the burrs on the rough blank. Since the shape of the grinding wheel is round, the cutting part and the sawing edge are uneven, and there are many residual cuts after cutting, which brings difficulties to the processing of the next process. Moreover, the true roundness of the product circumference cannot be guaranteed after cutting. The grinding wheel is prone to adverse phenomena in the subsequent process. For example, after magnification, there are obvious cracks on the edge. Therefore, the surface of the grinding wheel needs to be polished to eliminate defects such as burrs and gaps.

[0003] Existing grinding wheel polishing is mostly manual polishing. After the grinding wheel is fixed, a handheld polishing machine is used to rotate and polish the grinding wheel surface. When a large number of polishing operations are performed, the operation is cumbersome, time-consuming and labor-intensive. At the same time, long-term manual polishing can easily cause soreness and cramps in the operator's arms, resulting in non-standard polishing posture, which in turn leads to reduced accuracy.

[0018] In order to make the power column 4 rotate, the power column 4 is rotatably connected to the support plate 3. The lower end of the power column 4 passes through the support plate 3 and is coaxially provided with a transmission gear 10. The fixed column 8 is provided with a connecting plate located below the support plate 3, and a rotating motor 11 is provided on the connecting plate. A driving gear 12 that can mesh with the transmission gear 10 is coaxially provided on the output shaft of the rotating motor 11.

[0019] In order to rotate the rotating shaft 2, a rotating column 21 is coaxially provided on the rotating shaft 2, and a plurality of inclined grooves 13 corresponding to the power columns 4 one by one and penetrating up and down are provided on the rotating column 21. A rotating column 14 axially rotatable in the front and rear directions is provided on the left side of the rotating column 21, and a shifting column 15 which can be inserted into the inclined groove 13 is provided on the rotating column 14.

[0020] In order to rotate the rotating column 14 , a main motor 16 is provided at the upper end of the base plate 1 , and the main motor 16 is coaxially fixedly connected to the rotating column 14 .

[0021] In order to facilitate the positioning of the rotating shaft 2, a plurality of hemispherical slots 17 corresponding to the power columns 4 are provided at the upper end of the base plate 1. A fixing block 18 is coaxially provided on the rotating shaft 2. A fixing hole 19 is provided at the lower end of the fixing block 18 in an upper and lower axial direction. A fixing column 20 that can be inserted into the slot 17 is connected to the bottom surface of the fixing hole 19 via a spring.

[0022] When the utility model is in use, firstly, a plurality of grinding wheels 6 are placed on the power column 4 in sequence, so that the power column 4 is inserted into the mounting hole on the grinding wheel 6, and then the clamping nut 7 is rotated, the clamping nut 7 moves downward and realizes the compression and fixing of the corresponding grinding wheel 6 to prevent the grinding wheel 6 from rotating relative to the power column 4 during polishing, and then the plurality of grinding wheels 6 are fixed on the power column 4 in sequence, and the clamping nut 7 is used to fix the corresponding grinding wheel 6, and then the rotating motor 11 is turned on, and the rotating motor 11 drives the driving gear 12 to rotate, and the driving gear 12 drives the right power column 4 to rotate through the transmission gear 10, and the right power column 4 drives the grinding wheel 6 thereon to rotate, and then the right grinding wheel 6 contacts the polishing cotton 9, and the right grinding wheel 6 rotates so that the outer edge surface contacts the polishing cotton 9 and realizes rotation polishing;

[0023] At the same time, the main motor 16 is turned on, the main motor 16 drives the rotating column 14 to rotate, and the rotating column 14 drives the lever 15 to rotate clockwise. When the lever 15 rotates clockwise, the polishing cotton 9 realizes continuous polishing of the grinding wheel 6 on the right side. After the rotating column 14 rotates a certain angle, it drives the lever 15 to be inserted into one of the inclined grooves 13 from top to bottom, and drives the rotating column 21 to rotate counterclockwise through the inclined groove 13. The rotating column 21 drives the rotating shaft 2 to rotate counterclockwise. When the lever 15 slides out from the lower end of one of the inclined grooves 13 and breaks away from the rotating column 21, it drives the rotating column 21 to rotate 90 degrees counterclockwise.

[0024] The rotating column 21 drives the multiple power columns 4 and the grinding wheel 6 thereon to rotate counterclockwise by 90 degrees via the rotating shaft 2. The power column 4 originally located on the right side rotates counterclockwise by a certain angle and then disengages from the polishing cotton 9. At the same time, its corresponding transmission gear 10 disengages from the driving gear 12 and stops rotating. The power column 4 originally located on the front side rotates counterclockwise by 90 degrees and contacts the polishing cotton 9. At the same time, the transmission gear 10 thereon meshes with the driving gear 12 and drives the grinding wheel 6 to rotate, and the grinding wheel 6 starts to be polished.

[0025] After polishing the grinding wheel 6 for a period of time, the lever 15 is inserted into the corresponding inclined groove 13 from top to bottom again, and the shaft 2 is driven to rotate again. The above action is repeated to rotate the unpolished grinding wheel 6 originally on the left side until it contacts the polishing cotton 9 and rotates for polishing. This is repeated, and the surface polishing of multiple grinding wheels 6 can be automatically performed. When the shaft 2 rotates, the fixed block 18 on it is also driven to rotate. The fixed block 18 drives the clamping column 20 on it to slide out of the original clamping groove 17 and rotate and insert into the corresponding clamping groove 17, thereby fixing and limiting the shaft 2 to prevent the shaft 2 from rotating when the grinding wheel 6 is rotating and polishing. After all the polishing is completed, the rotating motor 11 and the main motor 16 are turned off, and then the clamping nut 7 is unscrewed, and the polished grinding wheel 6 is removed and replaced with the unpolished grinding wheel 6.

[0026] Compared with the prior art, the beneficial effects of the utility model are: the rotating shaft, rotating column 21, polishing cotton, etc. can realize automatic polishing of multiple grinding wheels and remove burrs and gaps on the surface of the grinding wheels. Compared with traditional manual polishing, the operation is simple and time-saving, and the polishing speed is uniform and the precision is high. The structure is simple, the conception is novel, the use is convenient, and the practicability is strong.

[0027] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0028] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
