[0002] A low shaft ring is a mechanical part, usually used in bearings to play a role in supporting and positioning. It is usually located below the shaft, bears axial loads, and helps to maintain the stability of the shaft.

[0003] The low shaft ring can bear the axial load from the shaft, ensuring the stability of the shaft during operation. It can help fix the position of the shaft, prevent axial displacement of the shaft during operation, reduce the direct contact between the shaft and other mechanical parts, reduce friction and wear, and improve the service life of the bearing.

[0004] The shaft collar and the shaft shoulder 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, rather than being detachable like a shaft sleeve. The low shaft ring is a process shaft ring for positioning and facilitating the disassembly and assembly of parts on the shaft or avoiding stress concentration, greatly improving the working efficiency of the assembly of shaft parts. The low shaft ring is applied to various shaft parts. However, in the prior art, the low shaft ring often loosens during operation, thus affecting the use effect of the low shaft ring.

[0029] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0030] A low shaft collar positioning tooling, such as Figure 1 - Figure 5As shown, it includes two groups of low shaft collar bodies 4. The two groups of low shaft collar bodies 4 are installed on the outer wall of the installation shaft 1. Both of the two groups of low shaft collar 1 bodies are provided with a first docking hole 5, a second docking hole 6, a third docking hole 7, and a fourth docking hole 8. The two groups of first docking holes 5 are respectively movably connected to the two groups of second docking holes 6, and the two groups of third docking holes 7 are respectively movably connected to the two groups of fourth docking holes 8. Fixed bolts 9 are movably installed on the inner walls of the two groups of first docking holes 5, and the two groups of fixed bolts 9 are respectively movably connected to the inner walls of the two groups of second docking holes 6. The fixed bolts 9 fixedly connect the first docking holes 5 and the second docking holes 6. Expansion columns 15 are movably installed inside the two groups of third docking holes 7, and the two groups of expansion columns 15 are respectively movably connected to the inner walls of the two groups of fourth docking holes 8. The expansion columns 15 fixedly connect the third docking holes 7 and the fourth docking holes 8. The two groups of expansion columns 15 are respectively movably connected to the two groups of fixed bolts 9, and the fixed bolts 9 drive the expansion columns 15 to displace.

[0031] Please refer to Figure 3 - Figure 4 , the outer walls of the two groups of fixed bolts 9 are respectively threadedly connected to the inner walls of the two groups of first docking holes 5, and the outer walls of the two groups of fixed bolts 9 are respectively threadedly connected to the inner walls of the two groups of second docking holes 6. Movable plates 10 are movably installed inside the two groups of second docking holes 6. The two groups of fixed bolts 9 rotate, and the outer walls of the two groups of fixed bolts 9 are respectively threadedly connected to the inner walls of the two groups of first docking holes 5. Therefore, the two groups of fixed bolts 9 displace. One ends of the two groups of fixed bolts 9 respectively move into the two groups of second docking holes 6, thereby pushing the two groups of movable plates 10 to displace.

[0032] Please refer to Figure 3 - Figure 4 , connecting rods 11 are movably installed inside the two groups of low shaft collar bodies 4, and one ends of the two groups of connecting rods 11 are respectively connected to the two groups of movable plates 10. Limit rings 12 are installed at the other ends of the two groups of connecting rods 11. The two groups of movable plates 10 displace, thereby driving the two groups of connecting rods 11 to displace, and further driving the two groups of limit rings 12 to displace.

[0033] Please refer to Figure 3 - Figure 4 , transmission shafts 13 are movably installed inside the two groups of low shaft collar bodies 4, and the outer walls of the two groups of transmission shafts 13 are respectively threadedly connected to the inner walls of the two groups of limit rings 12. Shrinkage cylinders 14 are movably installed inside the two groups of low shaft collar bodies 4, and the two groups of transmission shafts 13 are respectively connected to the two groups of shrinkage cylinders 14 through synchronous belts. The two groups of limit rings 12 displace, and the outer walls of the two groups of limit rings 12 are respectively threadedly connected to the outer walls of the two groups of transmission shafts 13. Therefore, the two groups of transmission shafts 13 rotate, thereby driving the two groups of shrinkage cylinders 14 to rotate.

[0034] Please refer to Figure 3 - Figure 4, the inner walls of the two sets of contraction cylinders 14 are respectively threadedly connected to the outer walls of the two sets of telescopic columns 15, and one ends of the two sets of telescopic columns 15 are provided with rounded corners. The inner walls of the two sets of fourth docking holes 8 are symmetrically installed with limiting blocks 16. One ends of the two sets of limiting blocks 16 are installed with springs 17, and the other ends of the two sets of limiting blocks 17 are provided with rounded corners. The outer walls of the two sets of telescopic columns 15 are symmetrically provided with limiting holes 18, and the multiple sets of limiting blocks 16 are respectively movably connected to the multiple sets of limiting holes 18. The two sets of contraction cylinders 14 rotate to drive the two sets of telescopic columns 15 to displace. One ends of the two sets of telescopic columns 15 respectively move into the two sets of fourth docking holes 8 and squeeze the multiple sets of limiting blocks 16. The multiple sets of limiting blocks 16 move into the inner walls of the two sets of third docking holes 7. When the two sets of telescopic columns 15 continue to displace and the multiple sets of limiting holes 18 respectively move to one ends of the multiple sets of limiting blocks 16, the multiple sets of first springs 17 push the multiple sets of limiting blocks 16 to displace, and one ends of the multiple sets of limiting blocks 16 respectively enter the multiple sets of limiting holes 18, thereby limiting the two sets of telescopic columns 15.

[0035] Please refer to Figure 2 - Figure 5 , one end of the mounting shaft 1 is provided with a shaft shoulder 2. The outer wall of the shaft shoulder 2 is symmetrically provided with limiting grooves 3, and the cross-sections of the two sets of limiting grooves 3 are both arc-shaped. The outer walls of the two sets of low shaft ring bodies 4 are both installed with mounting columns 19. One ends of the two sets of mounting columns 19 are both installed with limiting plates 20, and the two sets of limiting plates 20 respectively correspond to the two sets of limiting grooves 3. One ends of the two sets of limiting grooves 3 are both provided with grooves matching the limiting plates 20. The two sets of mounting columns 19 and the two sets of limiting plates 20 respectively enter the two sets of limiting grooves 3. Rotate the two sets of low shaft ring bodies 4 to drive the two sets of limiting plates 20 to respectively displace inside the two sets of limiting grooves 3, and the two sets of limiting plates 20 respectively enter the two sets of grooves.

[0036] Please refer to Figure 2 - Figure 5 , the outer walls of the two sets of low shaft ring bodies 4 are both movably installed with limiting columns 21, and the two sets of limiting columns 21 are respectively movably connected to the two sets of limiting grooves 3. One ends of the two sets of limiting columns 21 extending into the low shaft ring bodies 4 are both installed with second springs 22. When the two sets of low shaft ring bodies 4 are in contact with the shaft shoulder 2, the two sets of limiting columns 21 are squeezed. Rotate the two sets of low shaft ring bodies 4. When the two sets of limiting columns 21 respectively move to one ends of the two sets of limiting grooves 3, the two sets of second springs 22 push the two sets of limiting columns 21 to displace, and one ends of the two sets of limiting columns 21 enter the two sets of limiting grooves 3.

[0037] The working principle of the present utility model is as follows: When the installer installs the low shaft collar, the low shaft collar is composed of two groups of low shaft collar bodies 4. The two groups of low shaft collar bodies 4 are installed on the outer wall of the installation shaft 1 near one end of the shaft shoulder 2, and the two groups of first docking holes 5 correspond to the two groups of second docking holes 6 respectively, and the two groups of third docking holes 7 correspond to the two groups of fourth docking holes 8 respectively. Moreover, the two groups of installation posts 19 and the two groups of limiting plates 20 respectively enter the two groups of limiting grooves 3, and at the same time, the two groups of limiting posts 21 are squeezed. Rotate the two groups of low shaft collar bodies 4 to drive the two groups of limiting plates 20 to displace inside the two groups of limiting grooves 3 respectively. When the two groups of limiting posts 21 respectively move to one end of the two groups of limiting grooves 3, the two groups of second springs 22 push the two groups of limiting posts 21 to displace, and one end of the two groups of limiting posts 21 enters the two groups of limiting grooves 3, so that the two groups of low shaft collar bodies 4 are snap-connected with the shaft shoulder 2, and the two groups of low shaft collar bodies 4 complete the preliminary installation;

[0038] After the preliminary installation of the two groups of low shaft collar bodies 4 is completed, the operator rotates a fixing bolt 9 with a tool. The outer wall of the fixing bolt 9 is threadedly connected with the inner wall of the first docking hole 5, so the fixing bolt 9 displaces. One end of the fixing bolt 9 moves into the second docking hole 6, thereby pushing the movable plate 10 to displace, and then driving the connecting rod 11 to displace, and then driving the limiting ring 12 to displace. The outer wall of the limiting ring 12 is threadedly connected with the outer wall of the transmission shaft 13, so the transmission shaft 13 rotates;

[0039] When the transmission shaft 13 rotates, the transmission shaft 13 is connected with the contraction cylinder 14 through a synchronous belt, so the contraction cylinder 14 rotates. The inner wall of the contraction cylinder 14 is threadedly connected with the outer wall of the telescopic column 15, so the telescopic column 15 displaces. One end of the telescopic column 15 moves into the fourth docking hole 8 and squeezes the two groups of limiting blocks 16. The two groups of limiting blocks 16 move into the inner wall of the third docking hole 7. When the telescopic column 15 continues to displace and the two groups of limiting holes 18 respectively move to one end of the two groups of limiting blocks 16, the two groups of first springs 17 push the two groups of limiting blocks 16 to displace, and one end of the two groups of limiting blocks 16 respectively enters the two groups of limiting holes 18, thereby limiting the telescopic column 15 and completing the fixed connection of one end of the two groups of low shaft collar bodies 4. The other ends of the two groups of low shaft collar bodies 4 are fixed and connected in the above manner, thus completing the installation of the two groups of low shaft collar bodies 4, improving the fastening and stability of the low shaft collar installation, avoiding the frequent loosening of the low shaft collar during the working process, and further improving the use effect of the low shaft collar.
