Technical Field

[0001] The utility model relates to the technical field of coupler disassembly and assembly tools, and specifically relates to an on-line disassembly and assembly tool for a reducer coupler. Background Art

[0002] A reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a working machine, and plays a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or actuator.

[0003] In the prior art, a reducer unit mainly consists of a motor, a coupler, a coupling, and a reducer body. When the reducer unit is maintained, it is usually necessary to completely disassemble the above components, and then use a hammer and other tools to remove the coupler from the output shaft of the motor or the reducer. As a result, when forcibly knocking on the outside of the coupler, the coupler will be damaged, and the disassembly and assembly speed will be reduced, thus greatly affecting the loading and unloading operation of the coupler.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a technical solution. Please refer to Figure 1 and Figure 2 , an on-line disassembly and assembly tool for a reducer coupling, including: a limit seat 1, an assembly frame 2 and a reinforcing rib 3. The assembly frame 2 is assembled on the top of the limit seat 1, the reinforcing rib 3 is assembled between the limit seat 1 and the assembly frame 2. A limit frame 4 is inserted on the left side of the assembly frame 2, limit sleeves 5 are inserted on both sides of the limit frame 4, and a pulling mechanism 6 is assembled outside the limit frame 4.

[0025] The limit seat 1 can be fixed to the bottom of the reducer. The assembly frame 2 is convenient for assembling with an external puller or hydraulic rod through a connecting member, and then driving the limit frame 4 to move through the pulling mechanism 6. The reinforcing rib 3 can protect the outside of the reducer or the motor, and improve the overall strength of the assembly frame 2. The limit frame 4 can fix the coupling, and the limit sleeve 5 can fix the coupling. The inside of the limit sleeve 5 is hollow and can be sleeved outside the coupling.

[0026] Please refer to Figure 3 and Figure 4 , the pulling mechanism 6 includes a C-shaped arm 61 and a T-shaped plate 63. The C-shaped arm 61 is connected to the limit frame 4 through a trunnion seat. The trunnion seat includes a two-axis and a seat body. A pressing plate 62 is connected to the outside of the C-shaped arm 61. The T-shaped plate 63 is inserted into the inside of the limit frame 4, and a first spring 64 is assembled between the T-shaped plate 63 and the limit frame 4. The outside of the T-shaped plate 63 is connected to a connecting rod 65 through a hinge, and the other end of the connecting rod 65 is connected to the limit sleeve 5 through a hinge.

[0027] The U-shaped arm 61 can be assembled with a puller or a hydraulic rod by bolts. The pressing plate 62 can improve the stability of the U-shaped arm 61 after rotation and can drive the T-shaped plate 63 to move. The T-shaped plate 63 can be driven by a connecting rod 65 to带动 the two limit sleeves 5 to move relative to each other, and then fix the coupling.

[0028] Guide rails 41 are evenly arranged at the four corners on the right side of the limit frame 4, and the guide rails 41 are slidably connected to the reinforcing ribs 3. The guide rails 41 can enable the entire limit frame 4 to be driven to move linearly outside the assembly frame 2 by a puller or a hydraulic rod. Both ends of the outer part of the limit sleeve 5 are connected with T-shaped arms 51, and the T-shaped arms 51 are slidably connected with the limit frame 4. A second spring 52 is connected between the T-shaped arms 51 and the limit frame 4. The T-shaped arms 51 and the second spring 52 can guide the limit sleeve 5 to move linearly, and enable the limit sleeve 5 to return after the movement is completed.

[0029] C-shaped grooves are opened at both ends inside the limit frame 4. The inside of the limit frame 4 is slidably connected with the limit sleeve 5. The limit frame 4 can temporarily support the coupling through the C-shaped grooves inside. A square groove 42 is opened inside the limit frame 4, and the square groove 42 is slidably connected with the T-shaped plate 63. The square groove 42 can support the T-shaped plate 63. The outer part of the pressing plate 62 is designed with rounded corners, and the outer part of the pressing plate 62 contacts the top of the T-shaped plate 63. Through the rounded corner design, the pressing plate 62 can drive the T-shaped plate 63 to descend during rotation. At the same time, when the pressing plate 62 is in parallel contact with the T-shaped plate 63, it can maintain stability, thereby improving the stability during the assembly of the coupling. Assembly holes 11 are evenly arranged on the top of the limit seat 1, and sealing sleeves are embedded inside the assembly holes 11. The sealing sleeves and the assembly holes 11 facilitate the fixation of the limit seat 1 at the bottom of the reducer or the motor.

[0030] In this solution, first, the limit seat 1 is assembled at the bottom of the reducer or the motor. The groove outside the reinforcing rib 3 is sleeved on the output shaft of the reducer or the motor. The coupling is placed on the top of the limit frame 4. Then, the pulling mechanism 6 is rotated by 90° to make it perpendicular to the limit frame 4. Then, it is fixed with the U-shaped arm 61 by a puller or a hydraulic rod, so as to drive the limit frame 4 to move, and then cause the coupling to be assembled outside the output shaft of the reducer or the motor, and then complete the assembly operation. When the coupling needs to be disassembled, just run the above steps again to complete the disassembly.

[0031] At the same time, when the U-shaped arm 61 rotates, it will带动 the pressing plate 62 to squeeze the T-shaped plate 63 to descend, and then带动 the connecting rod 65 to drive, so as to带动 the two limit sleeves 5 to move relative to each other, wrap the coupling inside, and complete the fixation and protection of the coupling.

[0032] When the coupler is being loaded and unloaded, the coupler can be quickly fixed by the added reinforcing ribs 3, limit frame 4, limit sleeve 5 and pulling mechanism 6, and then the coupler can be loaded and unloaded from the outside of the device in conjunction with the puller or hydraulic rod, thereby greatly improving the coupler maintenance speed. At the same time, the added pulling mechanism 6, when driven by the puller or hydraulic rod, will automatically drive the limit sleeve 5 to fix the coupler, thereby improving the stability of the coupler during loading and unloading, and avoiding damage to the coupler caused by collision during loading and unloading.
