Abstract
Description
Technical Field
[0001] The utility model relates to the field of low shaft rings for machine tools, in particular to a low shaft ring for machine tools with strong wear resistance. Background Technique
[0002] Shaft rings are used for axial positioning of parts. The shaft shoulder and the shaft ring are the most reliable positioning methods for parts on the shaft. They are both structures on the shaft and belong to part of the shaft. The shaft ring is a separate ring-shaped part that can be sleeved onto the shaft and has the same function as the shaft shoulder. The shaft ring is used because directly using a shaft shoulder requires raw materials with a larger diameter, resulting in poor economy.
[0003] When existing machine tools are designed, components for easy fixing and rotation are installed on the shaft, and then bearings are sleeved on for use. Generally, there is a shaft shoulder on the shaft. However, since the shaft shoulder requires raw materials with a larger diameter, it consumes more financial resources. Using a shaft sleeve is too flexible and not suitable for the installation of some parts of the machine tool. A shaft ring can also be used.
[0004] Currently, the shaft ring needs to be directly sleeved on the machine tool part as a whole. During the sleeving process, it needs to pass through the entire machine tool part, and there may be situations of jamming and wear. When the shaft ring is not needed, it also needs to pass through the entire machine tool part and then be removed, and the operation is relatively complex and inconvenient. Content of the Utility Model
[0005] Based on this, the purpose of the utility model is to provide a low shaft ring for machine tools with strong wear resistance to solve the technical problem that the current shaft ring needs to be directly sleeved on the machine tool part as a whole, and there may be situations of jamming and wear during the sleeving process.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A low shaft ring for machine tools with strong wear resistance, including an upper ring. Installation grooves are provided on both sides of the upper ring. Installation blocks are fixed on both sides of the lower ring. A first connection groove is provided at the end of the upper ring. A second connection groove is provided at the end of the lower ring. A first fixing groove is provided on the inner wall of the first connection groove. A second fixing groove is provided inside the second connection groove. A connection block is installed inside the first connection groove. A first fixing block is fixed on one side of the connection block. A second fixing block is fixed on one side of the connection block.
[0007] By adopting the above technical solution, the collar is integrally disassembled into an upper ring and a lower ring, which enables the upper ring and the lower ring to be installed on the machine tool part that requires the use of the collar by inserting and extracting from above. When it is necessary to remove the collar from the machine tool part, only by pulling out the mounting block from the mounting groove, the upper ring and the lower ring can be separated, and then the whole collar can be removed from the machine tool part. This can solve the problem that the current collar needs to be directly sleeved on the machine tool part as a whole, and it may get stuck and worn during the sleeving process as it needs to pass through the entire machine tool part. When the collar is not needed, it also needs to pass through the entire machine tool part and then be removed, which is rather complicated and inconvenient to operate.
[0008] The present utility model is further configured such that a first magnet is fixed to the bottom of the connecting block, and a second magnet is fixed to the end of the mounting block.
[0009] By adopting the above technical solution, after the connecting block is placed into the first connecting groove and the second connecting groove, the connecting block can be firmly fixed inside the first connecting groove and the second connecting groove. With the aid of the second magnet, after the mounting block is placed into the mounting groove, the mounting block can be firmly fixed inside the mounting groove.
[0010] The present utility model is further configured such that the cross-sections of the mounting block and the first magnet are both T-shaped, and the outer walls of the mounting block and the first magnet are both in fit with the inner wall of the mounting groove.
[0011] By adopting the above technical solution, the mounting block can be better installed inside the mounting groove and will not slide out. By setting the shape of the first magnet to be T-shaped, the connecting block can be better installed inside the first connecting groove and the second connecting groove and will not fall out after installation.
[0012] The present utility model is further configured such that the materials of the first fixing block and the second fixing block are rubber materials, and the bottom surfaces of the first fixing block and the second fixing block are provided with inclined surfaces.
[0013] By adopting the above technical solution, setting the materials to rubber materials can increase the friction between the first fixing block and the first fixing groove, and can also increase the friction between the second fixing block and the second fixing groove. And by designing them into inclined surfaces, it is convenient to install them.
[0014] The present utility model is further configured such that a threaded hole is formed in one side of the lower ring, and a bolt is arranged inside the threaded hole.
[0015] By adopting the above technical solution, the collar is fixed on the shaft by using fixing screws to ensure the stable position of the component on the shaft, thus playing a role in fixing and positioning.
[0016] The utility model is further configured such that rubber pads are installed on the inner walls of the upper ring and the lower ring.
[0017] By adopting the above technical solution, the rubber pads are designed so that when the shaft collar is sleeved on a part of the machine tool, a large frictional force can be generated, ensuring that it will not fall off during the operation of the machine tool after installation.
[0018] To sum up, the utility model mainly has the following beneficial effects:
[0019] 1. By providing the upper ring, the lower ring, the installation groove and the installation block, the shaft collar is divided into two parts, the upper ring and the lower ring. The upper ring and the lower ring can be installed on the part of the machine tool where the shaft collar is needed by inserting from above. When it is necessary to remove the shaft collar from the machine tool part, only by pulling out the installation block from the installation groove, the upper ring and the lower ring can be separated, and then the whole shaft collar can be removed from the machine tool part. This can solve the problem that the current shaft collar needs to be directly sleeved on the machine tool part as a whole. During the sleeving process, it needs to pass through the whole machine tool part, which may cause jamming and wear. When the shaft collar is not needed, it also needs to pass through the whole machine tool part and then be removed, and the operation is relatively complex and inconvenient.
[0020] 2. By providing the connecting block, the first fixing groove and the second fixing groove, after the installation block is installed inside the installation groove, the upper ring and the lower ring are installed together at this time, but the upper ring and the lower ring are not completely fixed yet. It is necessary to install the connecting block into the first fixing groove and the second fixing groove, and use the connecting block to reinforce the installation between the upper ring and the lower ring, so that the shaft collar will not be displaced and fall off during use.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.
[0027] Next, according to the overall structure of the present invention, its embodiments will be described.
[0028] A low shaft collar for a machine tool with strong wear resistance, as Figure 1 - Figure 4 shown, includes an upper ring 1. Installation grooves 3 are provided on both sides of the upper ring 1. Installation blocks 4 are fixed on both sides of the lower ring 2. A first connection groove 5 is provided at the end of the upper ring 1. A second connection groove 12 is provided at the end of the lower ring 2. A first fixing groove 7 is provided on the inner wall of the first connection groove 5. A second fixing groove 8 is provided inside the second connection groove 12. A connection block 6 is installed inside the first connection groove 5. A first fixing block 9 is fixed on one side of the connection block 6. A second fixing block 10 is fixed on one side of the connection block 6. The shaft collar as a whole is disassembled into two parts, the upper ring 1 and the lower ring 2, which enables the upper ring 1 and the lower ring 2 to be installed on the machine tool part that requires the shaft collar by inserting and removing from above. When it is necessary to remove the shaft collar from the machine tool part, only by pulling out the installation block 4 from the installation groove 3, the upper ring 1 and the lower ring 2 can be separated, and then the shaft collar as a whole can be removed from the machine tool part, which can solve the problem that the current shaft collar needs to directly put the whole on the machine tool part, and it may get stuck and worn during the sleeving process as it needs to pass through the whole machine tool part. When the shaft collar is not needed, it also needs to pass through the whole machine tool part and then be removed, and the operation is relatively complicated and inconvenient.
[0029] Please refer to Figure 1 - Figure 2 , a first magnetic block 61 is fixed at the bottom of the connection block 6, and a second magnetic block 41 is fixed at the end of the installation block 4, so that after the connection block 6 is placed into the first connection groove 5 and the second connection groove 12, the connection block 6 can be firmly fixed inside the first connection groove 5 and the second connection groove 12. With the help of the second magnetic block 41, after the installation block 4 is placed into the installation groove 3, the installation block 4 can be firmly fixed inside the installation groove 3.
[0030] Please refer to Figure 1 - Figure 4 , the cross-sections of the installation block 4 and the first magnetic block 61 are both T-shaped, and the outer walls of the installation block 4 and the first magnetic block 61 are both fitted with the inner wall of the installation groove 3, so that the installation block 4 can be better installed inside the installation groove 3 and will not slide out. The shape of the first magnetic block 61 is set to be T-shaped, so that the connection block 6 can be better installed inside the first connection groove 5 and the second connection groove 12 and will not fall out after installation.
[0031] Please refer to Figure 2 The materials of the first fixing block 9 and the second fixing block 10 are rubber materials, and the bottom surfaces of the first fixing block 9 and the second fixing block 10 are beveled. Setting the material as rubber can increase the friction between the first fixing block 9 and the first fixing groove 7, and similarly, it can also increase the friction between the second fixing block 10 and the second fixing groove 8. And being designed as a bevel is convenient for installing it.
[0032] Please refer to Figure 1 and Figure 4 One side of the lower ring 2 is provided with a threaded hole, and a bolt is arranged inside the threaded hole. The collar is fixed on the shaft by using fixing screws to ensure the stable position of the component on the shaft, thus playing a role in fixing and positioning.
[0033] Please refer to Figure 1 and Figure 4 Rubber pads 11 are installed on the inner walls of the upper ring 1 and the lower ring 2. Designing the rubber pads 11 can generate a large amount of friction when the collar is sleeved on the machine tool part, so that it will not fall off during the operation of the machine tool after installation.
[0034] The working principle of the present utility model is as follows: When it is necessary to install the collar on the machine tool part, first place the upper ring 1 on the machine tool part where the collar is needed. Since the shapes and sizes of the mounting blocks 4 fixed on both sides of the lower ring 2 and the mounting grooves 3 opened on both sides of the upper ring 1 are the same, the mounting blocks 4 can be installed inside the mounting grooves 3 from above, and the second magnets 41 fixed on one side of the mounting blocks 4 are adsorbed inside the mounting grooves 3, so that the lower ring 2 and the upper ring 1 are installed outside the machine tool part.
[0035] After the installation is completed, the two connecting blocks 6 are installed inside the first connecting grooves 5 and the second connecting grooves 12 opened at the ends of the upper ring 1 and the lower ring 2. The shape of the lower half of the connecting block 6 is exactly the same as the shape and size of the mounting groove 3, and the mounting blocks 4 can be fixed inside the mounting grooves 3, so that during the use of the collar, the upper ring 1 and the lower ring 2 are fixedly installed. Since the shapes and sizes of the first fixing grooves 7 and the first fixing blocks 9 are exactly the same, and the shapes and sizes of the second fixing grooves 8 and the second fixing blocks 10 are exactly the same, and a first magnet 61 is fixed at the bottom end of the connecting block 6, the connecting block 6 can be tightly fixed and installed inside the first connecting groove 5.
