Description

Technical Field

[0001] The utility model belongs to the technical field of grinding machine accessories, and particularly relates to a grinding rod structure of a grinding machine. Background Art

[0002] A grinding machine is a device used for material processing and experimental analysis. It is usually used to grind materials or samples into fine particles or powders for subsequent analysis, experiments, or production processing. The basic function of a grinding machine is to grind and rub materials or samples at high speed through grinding media, gradually reducing their particle size to form the required powder or particles. Different types of grinding machines can be used to grind different kinds of materials, such as metals, hard materials, nano materials, etc. The grinding machine grinds materials through the grinding rod inside. When the grinding teeth on the surface of the grinding rod are damaged, since the grinding teeth and the grinding rod are integrally fixed structures, when replacing the grinding teeth, only the whole grinding rod can be disassembled for replacement, and the grinding teeth in the damaged area cannot be replaced individually, resulting in the existing grinding rod being inconvenient to replace and repair, and the replacement cost being relatively high. For this reason, we propose a grinding rod structure of a grinding machine. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a grinding rod structure of a grinding machine to solve the problem that the grinding rod of the grinding machine cannot replace the grinding teeth on the surface individually as mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A grinding rod structure of a grinding machine, including a rod body, a fixing ring with grinding teeth fixed at equal intervals on the surface is sleeved on the surface of the rod body. The fixing ring is composed of two equal semi-circular rings. Magnets are fixed at the ends of both semi-circular rings, and the ends of the two semi-circular rings are adsorbed and connected. A quick disassembly and assembly mechanism is arranged between the fixing ring and the rod body, and an installation and docking mechanism is arranged at the end of the rod body.

[0005] Preferably, the quick disassembly and assembly mechanism includes connection grooves symmetrically opened on both sides of the rod body and connection blocks symmetrically fixed on the inner side of the fixing ring. The connection blocks are snap-fitted with the connection grooves.

[0006] Preferably, clamping grooves are symmetrically opened on the surface of the connection block and clamping buckles symmetrically fixed on both sides of the inner wall of the connection groove. The clamping buckles are snap-fitted with the clamping grooves.

[0007] Preferably, positioning holes are symmetrically opened on both sides of the surface of the rod body relative to the connection grooves, and screw holes are symmetrically penetrated and opened on the inner side of the fixing ring. A positioning rod is arranged on the surface of the fixing ring, which passes through the inside of the screw hole and is connected with the positioning hole. The positioning rod is screwed and fixedly connected with the positioning hole.

[0008] Preferably, the installation and docking mechanism includes a docking groove formed at the end of the rod body.

[0009] Preferably, docking blocks are symmetrically fixed inside the docking groove.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] Through the designed fixing ring, magnet, connecting groove and connecting block, the present utility model can quickly replace the grinding teeth on the damaged area of the surface of the grinding rod. At the same time, with the designed positioning holes, screw holes and positioning rods, the replaced grinding teeth can be firmly positioned to avoid loosening. Compared with the existing technology, it greatly facilitates the use of the grinding rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a grinding rod structure of a grinding machine, including a rod body 1, a fixing ring 100 with grinding teeth 101 fixed at equal intervals on the surface of the rod body 1. The fixing ring 100 is composed of two equal semi-circular rings. Magnets 200 are fixed at the ends of both semi-circular rings, and the ends of the two semi-circular rings are adsorbed and connected. A quick disassembly and assembly mechanism is provided between the fixing ring 100 and the rod body 1, and an installation and docking mechanism is provided at the end of the rod body 1.

[0018] In this embodiment, preferably, the quick disassembly and assembly mechanism includes connection grooves 300 symmetrically formed on both sides of the rod body 1 and connection blocks 301 symmetrically fixed to the inner side of the fixed ring 100. The connection between the connection blocks 301 and the connection grooves 300 by snap connection facilitates the docking of the fixed ring 100 and the rod body 1.

[0019] In this embodiment, preferably, card slots 400 are symmetrically formed on the surface of the connection block 301 and clamping buckles 401 are symmetrically fixed to both sides of the inner wall of the connection groove 300. The connection between the clamping buckles 401 and the card slots 400 by snap connection facilitates temporarily limiting the connection block 101 inside the connection groove 100, enabling the positioning holes 500 and the screw holes 501 to be accurately aligned.

[0020] In this embodiment, preferably, positioning holes 500 are symmetrically formed on both sides of the rod body 1 relative to the connection grooves 300 and screw holes 501 are symmetrically formed through the inner side of the fixed ring 100. A positioning rod 502 is provided on the surface of the fixed ring 100, passing through the inside of the screw hole 501 and connecting with the positioning hole 500. By screwing and fixedly connecting the positioning rod 502 with the positioning hole 500, the fixed ring 100 can be firmly fixed to the surface of the rod body 1.

[0021] In this embodiment, preferably, the installation and docking mechanism includes a docking groove 600 formed at the end of the rod body 1.

[0022] In this embodiment, preferably, docking blocks 601 are symmetrically fixed inside the docking groove 600. When connecting the rod body 1 with the driving seat of the grinding machine, the docking blocks 601 and the docking groove 600 can play a role in docking and guiding.

[0023] The working principle and usage process of the present utility model: When the damaged grinding teeth 101 on the surface of the rod body 1 need to be replaced in the present utility model, first loosen all the positioning rods 502 on the surface of the fixed ring 100, so that their ends withdraw from the inside of the positioning holes 500 and are screwed into the inside of the screw holes 501, then the positioning of the fixed ring 100 can be released. Then, pull the fixed ring 100 to both sides respectively, so that the magnets 200 adsorbed and connected to its ends are pulled apart, and at the same time drive the connection blocks 301 to withdraw from the inside of the connection grooves 300, and at the same time drive the clamping buckles 401 to be separated from the card slots 400 by extrusion, then the fixed ring 100 and the rod body 1 can be disassembled. Then replace the intact grinding teeth 101 on the surface, and then install the fixed ring 100 on the surface of the rod body 1. When the rod body 1 needs to be connected with the driving seat of the grinding machine, the docking blocks 601 and the docking groove 600 can play a role in docking and guiding.
