Description

Technical Field

[0001] The utility model relates to the technical field of grinding discs, in particular to a firmly installed grinding disc. Background Art

[0002] Grinding discs are used for grinding. For example, if the burrs and weld nodules on the surface of the workpiece need to be ground, the grinding disc is installed on the angle grinder to grind off the burrs and smooth the weld nodules. The grinding disc uses high-voltage electrostatic field force to plant fine abrasive grains on high-strength polyester film, so that all the sand grains are pointed outward, cutting is sharp, and can provide higher grinding efficiency and bright and delicate polishing effect, and then it is processed by backing and cutting.

[0003] When the abrasive particles are consumed during use, the abrasive disc needs to be replaced. However, most existing abrasive discs are connected to external driving devices via bolts, which makes disassembly and assembly of the abrasive disc inconvenient, time-consuming and labor-intensive, and affects work efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a firmly installed grinding disc to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a firmly installed grinding disc, comprising:

[0006] The cam is provided with a plurality of through grooves, and the through grooves are arranged between the plurality of movable blocks and the plurality of movable blocks.

[0007] Preferably, a plurality of plug-in posts are fixedly welded on the top wall of the grinding disc body, and a plurality of plug-in holes matching the plug-in posts are opened on the mounting plate.

[0008] Preferably, a plurality of annular grooves equidistantly distributed are formed on the bottom wall of the mounting plate, a heat conducting sheet is fixedly bonded in the groove, and a plurality of heat sinks are fixedly bonded on the top wall of the heat conducting sheet.

[0009] Preferably, the connecting block is matched with the through slot, and the plug-in block is matched with the plug-in slot.

[0010] Preferably, the heat sink is arranged in an arc shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the utility model is in use, the mounting plate is first fixed on the rotating shaft of the driving device by bolts, and then the grinding plate body is installed. The specific operation steps are to press the two pressing blocks toward the center of the mounting plate at the same time, drive the two moving blocks to move toward each other, stretch the tension spring and drive the plug-in block away from the fixed seat at the corresponding position, and then align the two connecting blocks of the grinding plate body with the two through grooves and insert them. When the top wall of the grinding plate body fits the bottom wall of the mounting plate, release the two pressing blocks at the same time, so that the moving block drives the plug-in block to be inserted into the plug-in groove under the tension of the tension spring, and the connecting block is locked, thereby realizing the rapid installation of the grinding plate body, facilitating the rapid replacement of the grinding plate body after the abrasive grains of the grinding plate body are consumed, and the operation is simple and fast.

[0013] 2. The utility model cooperates with the heat conducting sheet and the heat sink, so that when the grinding plate body is grinding, the heat generated by friction can be conducted to the heat sink through the heat conducting sheet. During the rotation of the heat sink, the heat is dissipated into the air, thereby realizing rapid heat dissipation of the grinding plate body and avoiding the problem of shortening the service life of the grinding plate body due to long-term high temperature.

[0021] The mounting plate 1 is provided with a mounting hole 2, a grinding disc body 3 is provided at the bottom of the mounting plate 1, and two plug-in mechanisms 4 are provided on the mounting plate 1, and the plug-in mechanism 4 includes a fixed seat 5, and the fixed seat 5 is fixedly welded on the top wall of the mounting plate 1, and a pressing block 6 is slidably connected to the fixed seat 5, and a moving block 7 is fixedly welded at one end of the pressing block 6 close to the center of the mounting plate 1, and a pair of tension springs 8 are fixedly installed at an upper position of a side wall of the moving block 7 close to the fixed seat 5, and one end of the tension spring 8 away from the moving block 7 is fixedly bonded to the fixed seat 5, and a plug-in block 9 is fixedly welded at a lower position of a side wall of the moving block 7 close to the fixed seat 5, and two through grooves 10 are provided on the mounting plate 1, and the through grooves 10 are provided between the moving block 7 and the fixed seat 5, and two connecting blocks 11 are fixedly welded on the top wall of the grinding disc body 3, and plug-in grooves 12 are provided on both of the two connecting blocks 11.

[0022] A plurality of plug-in posts 13 are fixedly welded on the top wall of the grinding disc body 3, and a plurality of plug-in holes 14 compatible with the plug-in posts 13 are opened on the mounting plate 1. By plugging and fitting the provided plug-in posts 13 and the plug-in holes 14, the force of the connecting block 11 during grinding of the grinding disc body 3 can be shared, thereby preventing the connecting block 11 from being easily broken.

[0023] The bottom wall of the mounting plate 1 is provided with a plurality of annular grooves 15 which are evenly distributed. A heat conducting sheet 16 is fixedly bonded in the groove 15. A plurality of heat sinks 17 are fixedly bonded on the top wall of the heat conducting sheet 16. The heat generated during the grinding of the grinding disc body 3 can be transferred to the heat sink 17 through the heat conducting sheet 16. The heat sink 17 dissipates the heat into the air during the rotation process, thereby realizing rapid heat dissipation of the grinding disc body 3.

[0024] The connecting block 11 is matched with the through slot 10 , and the plug-in block 9 is matched with the plug-in slot 12 , so as to prevent the grinding disc body 3 from shaking on the mounting plate 1 after installation.

[0026] Working principle: When the utility model is in use, the mounting plate 1 is first fixed on the rotating shaft of the driving device by bolts, and then the grinding plate body 3 is installed. The specific operation steps are to press the two pressing blocks 6 toward the center of the mounting plate 1 at the same time, drive the two moving blocks 7 to move toward each other, stretch the tension spring 8 and drive the plug-in block 9 away from the fixed seat 5 at the corresponding position, and then align the two connecting blocks 11 of the grinding plate body 3 with the two through grooves 10 respectively and insert them. When the top wall of the grinding plate body 3 is in contact with the bottom wall of the mounting plate 1, the two pressing blocks 6 are released at the same time, so that the moving block 7 is under the tension of the tension spring 8. Drive the plug-in block 9 to insert it into the plug-in slot 12 and lock the connecting block 11, so as to realize the rapid installation of the grinding plate body 3, and facilitate the rapid replacement of the grinding plate body 3 after the abrasive particles of the grinding plate body 3 are consumed. The operation is simple and fast. Through the cooperation of the provided heat conducting plate 16 and the heat sink 17, when the grinding plate body 3 is grinding, the heat generated by friction can be conducted to the heat sink 17 through the heat conducting plate 16. During the rotation process, the heat sink 17 dissipates the heat into the air, so as to realize the rapid heat dissipation of the grinding plate body 3 and avoid the problem of shortening the service life of the grinding plate body 3 due to long-term high temperature.
