Description

Technical Field

[0002] Resin grinding wheel is a grinding wheel made of resin with high strength. It is used in cutting discs, double-end faces, heavy-load grinding wheels, polishing wheels, etc. It is widely used in rough grinding, rough grinding, cutting off and free grinding, such as grinding steel ingots and deburring castings.

[0003] During the cutting process, the existing resin grinding wheel cutting disc will generate a lot of heat between the grinding wheel cutting disc itself and the workpiece during the rotation process. During the cutting process, the heat of the grinding wheel cutting disc itself and the workpiece is difficult to dissipate quickly, resulting in poor heat dissipation performance of the resin grinding wheel cutting disc, which is easy to burn the grinding wheel and the workpiece, thereby affecting the cutting strength of the workpiece. In addition, the resin grinding wheel cutting disc is generally installed on the rotating shaft with a flange. If the grinding wheel needs to be replaced after installation, it takes a lot of time to disassemble and assemble, which makes the replacement efficiency too low. In view of this, a high-strength resin grinding wheel is proposed. 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] See also Figure 1-3 The utility model provides a new technical solution: a high-strength resin grinding wheel, comprising a grinding wheel body 1, a mounting shaft 5 is arranged on the upper surface of the grinding wheel body 1, and a hollow column 4 is fixedly installed on the upper surface of the grinding wheel body 1;

[0026] The heat dissipation mechanism is arranged on the grinding wheel body 1, and is used for heat dissipation treatment on the surface of the grinding wheel body 1. The heat dissipation mechanism includes a heat conduction groove 2, and the heat conduction groove 2 is opened on the upper surface of the grinding wheel body 1;

[0027] The disassembly and assembly mechanism is arranged on the grinding wheel body 1 and is used for disassembling and assembling the grinding wheel body 1 . The disassembly and assembly mechanism also includes a first magnetic ring 12 , and the first magnetic ring 12 is fixedly mounted on the inner surface of the hollow column 4 .

[0028] Furthermore, a heat dissipation hole 3 is provided on the upper surface of the grinding wheel body 1 .

[0029] Furthermore, a slide groove 6 is provided on the outer surface of the hollow column 4 , and two round holes 10 are provided on the inner wall of the slide groove 6 , and two round balls 11 are arranged in the two round holes 10 .

[0030] Furthermore, the disassembly and assembly mechanism also includes two springs 7, two pressure plates 8 and a ring 9. The two springs 7 are fixedly installed in the inner wall of the slide groove 6, the two pressure plates 8 are fixedly installed on the upper ends of the two springs 7, and the opposite surfaces of the two pressure plates 8 are inclined.

[0031] Furthermore, two clamping holes 14 are formed on the outer surface of the mounting shaft 5 .

[0032] Furthermore, the disassembly and assembly mechanism also includes a second magnetic ring 13, which is fixedly mounted on the lower end of the mounting shaft 5. When the high-strength resin grinding wheel is in use, a downward thrust is applied to the circular ring 9 to make it slide downward in the slide groove 6. The circular ring 9 drives the two pressure plates 8 fixedly mounted on the inner surface to move downward, and the two pressure plates 8 apply pressure to the two springs 7 fixedly mounted on the lower surface to cause them to shrink. At the same time, the two pressure plates 8 are no longer located above the two circular holes 10, and at the same time, pressure is no longer applied to the two round balls 11 in the two circular holes 10. At this time, by inserting the hollow column 4 into the outer surface of the mounting shaft 5, pressure is no longer applied to the circular ring 9, and at the same time, the two springs 7 are no longer under force. At this time, the two springs 7 expand, and the two springs 7 apply an upward thrust to the two pressure plates 8 fixedly mounted on the upper ends to make them move upward. While moving, the inclined surfaces of the two pressure plates 8 hit the two round balls 11, causing them to move toward the opposite surface and be clamped into the two clamping holes 14 opened on the outer surface of the mounting shaft 5 for fixation. The first magnetic ring 12 and the second magnetic ring 13 are attracted to each other and strengthened and fixed. At this time, the installation is completed. When it needs to be disassembled, it can be done by repeatedly pushing the ring 9 upward. At this time, the grinding wheel body 1 is driven to rotate by the rotation of the installation shaft 5. During rotation, the heat is discharged through the heat conduction groove 2 and the heat dissipation hole 3 opened on the upper surface of the grinding wheel body 1, which is used for heat dissipation treatment of the surface of the grinding wheel body 1 to prevent the surface from being heated to form high temperature and causing a reduction in service life. The high-strength resin grinding wheel can be quickly disassembled and assembled by a snap-on method. Compared with the flange installation connection method, this method can realize rapid installation and disassembly when replacing the high-strength grinding wheel, can quickly complete the fixation, save the time required for replacing the grinding wheel, and is more convenient. In addition, the high-strength resin grinding wheel can dissipate the heat on the surface of the grinding wheel body 1 through the heat conduction groove 2 and the heat dissipation hole 3, so that the surface cools down more quickly, thereby improving the service life of the high-strength resin grinding wheel body, which is more convenient.

[0033] Working principle: When the high-strength resin grinding wheel is used, a downward thrust is applied to the circular ring 9 to make it slide downward in the slide groove 6. The circular ring 9 drives the two pressure plates 8 fixedly mounted on the inner surface to move downward. The two pressure plates 8 apply pressure to the two springs 7 fixedly mounted on the lower surface to cause them to shrink. At the same time, the two pressure plates 8 are no longer located above the two circular holes 10, and no pressure is applied to the two round balls 11 in the two circular holes 10. At this time, the hollow column 4 is inserted into the outer surface of the mounting shaft 5. At this time, the circular ring 9 is no longer pressed, and the two springs 7 are no longer under force. At this time, the two springs 7 expand, and the two springs 7 apply a force to the two pressure plates 8 fixedly mounted on the upper end. The thrust on the two pressure plates 8 makes it move upward, and while moving, the inclined surfaces of the two pressure plates 8 hit the two round balls 11, making them move toward the opposite surface, and are snapped into the two snap holes 14 opened on the outer surface of the installation shaft 5 for fixation. At the same time, the first magnetic ring 12 and the second magnetic ring 13 attract each other to strengthen the fixation. At this time, the installation is completed. When it needs to be disassembled, it can be done by repeatedly pushing the ring 9 upward. At this time, the rotation of the installation shaft 5 drives the grinding wheel body 1 to rotate. During rotation, heat is discharged through the heat conduction grooves 2 and heat dissipation holes 3 opened on the upper surface of the grinding wheel body 1, which is used for heat dissipation treatment of the surface of the grinding wheel body 1 to prevent its surface from being heated to form high temperature and causing a reduction in service life.
