[0028] After the positioning ring 19 is clamped and fixed by the clamping mechanism, it is necessary to install the positioning ring 19 inside the body 6 of the door machine rotary reduction box. Start the motor 13, drive the first gear 23 to rotate through the motor 13, drive the second gear 24 to rotate through the first gear 23, drive the threaded rod 18 to rotate inside the threaded sleeve 7 through the second gear 24, so that the threaded sleeve 7 slowly rises inside the box body 17, drive the clamping mechanism to slowly rise through the threaded sleeve 7, and drive the positioning ring 19 to slowly enter the inside of the body 6 of the door machine rotary reduction box through the clamping mechanism. Compared with the traditional tooling, this tooling, through the cooperation between the threaded sleeve 7, the threaded rod 18, etc., is convenient to drive the positioning ring 19 to slowly enter the fixed plate 2, ensuring that the installation position is accurate, improving the accuracy. At the same time, it simplifies the installation process, realizes fast and efficient installation, shortens the maintenance cycle, has a stable support and clamping function for the tooling, effectively prevents the positioning ring from falling, ensures the operation safety, its reasonable design avoids local compression and wear of the equipment, extends the service life, the tooling stably installs the positioning ring, reduces the vibration and shaking during the operation of the equipment, ensures the stable operation and reliability of the door machine rotary reduction box, and provides a solid guarantee for the overall operation efficiency and safety.

[0029] Among them, the clamping mechanism is fixedly installed at the top of the threaded sleeve 7. The clamping mechanism includes a fixed groove 14 fixedly installed at the top of the threaded sleeve 7. A sliding groove 26 is opened inside the fixed groove 14. A sleeve block 22 is movably installed inside the sliding groove 26. A bidirectional lead screw 12 is threadedly sleeved inside the sleeve block 22, and both ends of the bidirectional lead screw 12 penetrate through the inside of the lifting plate 4. One end of the bidirectional lead screw 12 is fixedly installed with a rotating disk 8;

[0030] The top of the sleeve block 22 is fixedly installed with a moving plate 20. A spring 27 is fixedly installed inside the inner side of the moving plate 20. One end of the spring 27 is fixedly installed with an arc-shaped clamping block 21. A second telescopic rod 25 is fixedly installed between the arc-shaped clamping block 21 and the moving plate 20.

[0031] Before the positioning ring 19 is used, the staff needs to clamp and fix the positioning ring 19. First, place the positioning ring 19 on the top of the fixed groove 14, and then hold the rotating disk 8 and rotate it. Drive the bidirectional lead screw 12 to rotate inside the sleeve block 22 through the rotating disk 8, so that the sleeve block 22 slowly approaches the positioning ring 19. Drive the moving plate 20 to move slowly through the sleeve block 22, drive the movement between the second telescopic rod 25 and the spring 27 through the moving plate 20, and move the arc-shaped clamping block 21 through the second telescopic rod 25 and the spring 27, and clamp and fix the positioning ring 19 through the arc-shaped clamping block 21. Limit and fix the arc-shaped clamping block 21, the second telescopic rod 25 and the spring 27 through the positioning ring 19, so as to complete the clamping and fixing of the positioning ring 19.

[0032] Before using the positioning ring 19, it is necessary to clamp and fix the positioning ring 19. First, place the positioning ring 19 on the top of the fixing groove 14, and then hold the rotating disk 8 and rotate it. By driving the bidirectional lead screw 12 to rotate inside the sleeve block 22 through the rotating disk 8, the sleeve block 22 slowly approaches the positioning ring 19. The sleeve block 22 drives the moving plate 20 to move slowly, and the moving plate 20 drives the movement between the second telescopic rod 25 and the spring 27. Then, through the second telescopic rod 25 and the spring 27, the arc-shaped clamping block 21 is moved, and the positioning ring 19 is clamped and fixed by the arc-shaped clamping block 21. Compared with the traditional tooling, through the cooperation between the sleeve block 22 and the threaded rod 18, this tooling facilitates driving the arc-shaped clamping block 21 to limit and fix the positioning ring 19, significantly improving the operation accuracy. Its clamping and fixing ensure the precise fixation of the positioning ring, avoiding manual errors. The tooling also speeds up the installation and disassembly speed, shortens the maintenance time, and improves the operation efficiency. At the same time, the tooling effectively prevents the accidental movement of the positioning ring 19, ensuring operation safety. Through uniform clamping and stable limiting, the tooling protects the positioning ring 19 from damage, extends its service life, and reduces potential damage to the rotary reduction gearbox and its components during the replacement process, comprehensively ensuring the stability and maintenance quality of the equipment.

[0033] Among them, a fixing groove 14 is opened inside the fixing plate 2, and a fixing block 16 is movably installed inside the fixing groove 14. A toolbox 15 is fixedly installed on the back of the fixing block 16.

[0034] By holding the toolbox 15 by hand, the fixing block 16 is driven by the toolbox 15 to slowly enter the inside of the fixing groove 14, and the fixing block 16 is limited and fixed by the fixing groove 14. By adding the toolbox 15, it is convenient for the staff to take maintenance tools inside the toolbox 15 for use, improving the use efficiency of the maintenance tools.

[0035] Among them, a threaded hole 3 is opened inside the door machine rotary reduction gearbox body 6, and the threaded holes 3 are arranged in a circumferential array.

[0036] Since the threaded holes 3 are arranged in a circumferential array inside the door machine rotary reduction gearbox body 6, now bolts are screwed into the threaded holes 3 and the inside of the threaded holes 3, which ensures the stability of the door machine rotary reduction gearbox body 6 during use and improves the efficiency of the door machine rotary reduction gearbox body 6 during use.

[0037] Among them, columns 10 are fixedly installed around the bottom of the support plate 1, and a base 11 is fixedly installed at the bottom of the columns 10.

[0038] Through the cooperation between the base 11 and the columns 10, it is convenient to support the support plate 1, and the precise position of the support plate 1 during installation can be ensured, reducing errors caused by human factors, thereby improving the accuracy of the lower positioning ring replacement.

[0039] Among them, a telescopic rod 9 is fixedly installed at the bottom of the lifting plate 4 and the top of the support plate 1, and the telescopic rod 9 presents four shapes of the same size.

[0040] Since the telescopic rod 9 presents four shapes of the same size at the bottom of the lifting plate 4 and the top of the support plate 1, it is convenient to support the lifting plate 4 during the up and down movement, ensure the stability of the lifting plate 4 during use, and reduce the shaking of the lifting plate 4 during use.

[0041] The inner diameter of the fixing groove 14 is equal to the outer diameter of the fixing block 16 , and the interior of the fixing groove 14 is designed to be smooth.

[0042] Since the interior of the fixing groove 14 is designed to be smooth, it is convenient to place the fixing block 16 into the fixing groove 14 . The fixing block 16 is limited and fixed by the fixing groove 14 , thereby improving the use efficiency of the fixing block 16 .

[0043] The telescopic rods 25 and the springs 27 are arranged in pairs, and there are two groups in total inside the moving plate 20 and the arc-shaped clamping block 21 .

[0044] Since the telescopic rod 25 and the spring 27 are grouped in pairs, there are two groups in total inside the movable plate 20 and the arc-shaped clamping block 21. Through the cooperation between the telescopic rod 25 and the spring 27, it is convenient to provide stable support for the arc-shaped clamping block 21, and the stability of the arc-shaped clamping block 21 during use.

[0045] An anti-skid pad 28 is fixedly installed inside the arc-shaped clamping block 21 , and the anti-skid pad 28 is made of rubber material.

[0046] Since the anti-skid pad 28 is made of rubber material and is inside the arc-shaped clamping block 21, the anti-skid pad 28 made of rubber material can effectively increase the friction between the positioning ring 19 and reduce the sliding of the positioning ring 19 during use.

[0047] A motor protection cover 29 is fixedly mounted on the outer surface of the motor 13 , and heat dissipation holes are provided inside the motor protection cover 29 .

[0048] Since the motor protection cover 29 is provided with heat dissipation holes, the motor 13 is easily dissipated to ensure the temperature stability of the motor 13 during use. At the same time, the motor protection cover 29 supports the motor 13 to reduce the shaking of the motor 13 during use.

[0049] The working principle and use process of this utility model:

[0050] After the positioning ring 19 is clamped and fixed by the clamping mechanism, the positioning ring 19 needs to be installed inside the main body 6 of the door machine rotary reduction box. Then, the motor 13 is turned on. The motor 13 drives the first gear 23 to rotate. Through the tooth engagement between the first gear 23 and the second gear 24, the first gear 23 drives the second gear 24 to rotate. The second gear 24 drives the threaded rod 18 to rotate inside the threaded sleeve 7, causing the threaded sleeve 7 to slowly rise inside the box body 17. The threaded sleeve 7 drives the clamping mechanism to slowly rise, and the clamping mechanism drives the positioning ring 19 to slowly enter the bottom of the main body 6 of the door machine rotary reduction box, thus completing the installation of the positioning ring 19.

[0051] Before using the positioning ring 19, the positioning ring 19 needs to be clamped and fixed. First, place the positioning ring 19 on the top of the fixing groove 14, and then hold the rotating disc 8 and rotate it. The rotating disc 8 drives the bidirectional lead screw 12 to rotate inside the sleeve block 22, causing the sleeve block 22 to slowly approach the positioning ring 19. The sleeve block 22 drives the moving plate 20 to move slowly. The moving plate 20 drives the movement between the second telescopic rod 25 and the spring 27. Then, the second telescopic rod 25 and the spring 27 move the arc-shaped clamping block 21, and the arc-shaped clamping block 21 clamps and fixes the positioning ring 19. The positioning ring 19 limits and fixes the arc-shaped clamping block 21, the second telescopic rod 25 and the spring 27, thus completing the clamping and fixing of the positioning ring 19.
