Description

Technical Field

[0001] This utility model relates to the field of core component grinding technology, specifically a grinding device for core component production. Background Technology

[0002] Grinding core components is an indispensable part of manufacturing. It involves improving the surface quality of parts, removing burrs, and improving appearance. With the development of technology, modern grinding processes not only pursue high efficiency, but also ensure precision and consistency. Grinding components ensures their quality.

[0003] In existing parts grinding devices, the grinding disc is mostly installed on the mounting base inside the grinding device's protective cover by bolts. Because the grinding disc drives the sandpaper for a long time, the grinding disc is extremely easy to be damaged. However, fixing the grinding disc with bolts makes the disassembly and assembly process for replacing the grinding disc cumbersome, time-consuming and labor-intensive, affecting the working efficiency of the grinding device. Furthermore, the grinding disc is not securely installed on the mounting base by bolts alone, and loose bolts can easily cause the grinding disc to fall off the mounting base, creating a safety hazard. Utility Model Content

[0004] To address the problems that bolt-fixed grinding discs lead to cumbersome and time-consuming disassembly and assembly processes when replacing them, affecting the efficiency of the grinding device, and that loose bolts can cause the grinding disc to detach from the mounting base, posing a safety hazard; the purpose of this utility model is to provide a grinding device for the production of core components.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a grinding device for the production of core components, including a protective cover, a motor fixedly installed in the middle of the bottom surface of the protective cover, a rotating shaft fixedly installed at the output end of the motor, one end of the rotating shaft penetrating the protective cover and fixedly installed with a mounting base, the mounting base being rotatably installed inside the protective cover, a grinding disc being detachably installed on the top surface of the mounting base, a first positioning hole and a second positioning hole being respectively opened in the middle of the mounting base and the grinding disc, the first positioning hole and the second positioning hole being interconnected, and a positioning component being detachably installed in the first positioning hole and the second positioning hole;

[0006] The positioning component includes a positioning element, which is slidably installed in a first positioning hole and a second positioning hole. Guide seats are symmetrically installed on both sides of the positioning element. A positioning pin is fixedly installed on one side of the guide seat. A return spring is symmetrically installed on the side of the guide seat away from the positioning pin. Connecting brackets are fixedly connected to one side of the two guide seats on the same side of the positioning element. There are two connecting brackets, which slide relative to each other in the positioning element. Positioning insertion holes are opened on both sides of the first positioning hole and the second positioning hole. The positioning pin is slidably inserted into the positioning insertion hole through the guide seat and the return spring.

[0007] Preferably, the bottom surface of the grinding disc is fixedly equipped with evenly distributed positioning rings, and the top surface of the mounting base is provided with evenly distributed positioning grooves. There are four positioning rings and four positioning grooves, and the four positioning rings are slidably inserted into the four positioning grooves respectively.

[0008] Preferably, guide strips are fixedly installed on both sides of the positioning member, and guide grooves are opened on both sides of the second positioning hole. There are two guide strips and two guide grooves, and the two guide strips are slidably installed in the two guide grooves respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, the grinding disc is installed inside the protective cover by using the mounting base and positioning component. When the grinding disc needs to be disassembled, the positioning pin is taken out from the corresponding positioning hole, and the positioning component is taken out from the first positioning hole and the second positioning hole by the push-pull component. The disassembly of the grinding disc on the mounting base can be completed. This solves the problem that when the grinding disc is fixed with bolts, the disassembly and assembly process is more cumbersome, time-consuming and labor-intensive, and affects the working efficiency of the grinding device.

[0011] 2. In this utility model, the four positioning rings on the bottom surface of the grinding disc and the four positioning grooves on the top surface of the mounting base ensure the normal installation of the positioning components in the later stage. At the same time, it increases the stability and firmness of the grinding disc after it is installed on the top surface of the mounting base, and solves the problem that the grinding disc may fall off the mounting base due to loose bolts, which may cause safety hazards.
