Description

Technical Field

[0001] This utility model relates to the technical field of mounting plates for fixing, specifically a reducer mounting plate for industrial robot joints. Background Technology

[0002] The reducer for industrial robot joints mainly consists of three components: a wave generator, a flexible gear, and a rigid gear. Its primary function is to use the wave generator to induce controllable elastic deformation in the flexible gear, which then meshes with the rigid gear to transmit power. In the reducer's structure, the wave generator acts as the driving force, the rigid gear is used for fixing, and the flexible gear is used for output. The wave generator has an elliptical cross-section, with rollers formed by rolling bearings mounted at its ends. These rollers press against the inner wall of the flexible gear. When the wave generator is inserted into the flexible gear, the flexible gear undergoes elastic deformation. The teeth at both ends of the flexible gear's long shaft fully mesh with the teeth of the rigid gear, while the teeth at both ends of the flexible gear's short shaft completely disengage from the rigid gear. During normal operation, the rigid gear needs to be fixed, and power is transmitted via a motor. The wave generator rotates, driving the flexible gear output, which in turn drives the load. Typically, a mounting plate is needed between the motor and the wave generator to secure the wave generator, ensuring a reliable connection between the motor shaft and the wave generator. To simplify the installation process, a Ф50 circular mounting hole is usually provided on the wave generator mounting plate, through which the wave generator connects to the motor output shaft. However, existing reducer mounting plates are mostly fixed directly to the reducer housing with bolts, making it difficult to disassemble, maintain, or replace the mounting plate during subsequent use, thus hindering its use. Therefore, a reducer mounting plate for industrial robot joints is proposed. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a reducer mounting plate for industrial robot joints, which has the following advantages:

[0014] The reducer mounting plate for the industrial robot joints rotates by turning the second handwheel, which in turn rotates the mounting shaft and the take-up roller. The rotating roller winds up the traction rope, causing the slider and positioning block to move to the right. This moves the positioning block out of the positioning groove, releasing the positional constraint on the fixed block. Then, turning the first handwheel rotates the rotating shaft and the drive gear, which in turn drives two threaded rods to rotate synchronously via two driven gears. During rotation, the two threaded rods move the fixed block downwards, removing it from the fixing groove and releasing the connection between the connecting block and the mounting block. At this point, pulling the mounting plate forward allows for easy removal without disassembling the bolts, facilitating maintenance or replacement of the mounting plate. Attached Figure Description

[0023] The bottom of the mounting block 1 has a first groove 13 located below the rectangular groove 7. A rotating component 14 is movably mounted on the inner top wall of the first groove 13, extending into the rectangular groove 7 and fixedly connected to the outside of the two threaded rods 8. The rotating component 14 includes a rotating shaft 141. The inner top wall of the first groove 13 is movably mounted with a rotating shaft 141 extending into the rectangular groove 7.

A drive gear 142 located between the two threaded rods 8 is fixedly mounted on the top outer side of the rotating shaft 141. A driven gear 143 located below the fixing block 10 and meshing with the drive gear 142 is fixedly mounted on the outer side of each of the two threaded rods 8.

[0024] The mounting block 1 has a mounting cavity 15 located to the right of the fixing block 10 and below the connecting groove 3. A slider 16 is movably mounted inside the mounting cavity 15. A positioning groove 17 is provided at the bottom right side of the fixing block 10. A positioning block 18 is fixedly mounted on the left side of the slider 16, with one end extending into the positioning groove 17. A through hole is provided on the mounting block 1 and adapted to the positioning block 18 between the left side of the inner wall of the mounting cavity 15 and the right side of the inner wall of the rectangular groove 7.

[0025] The bottom of the mounting block 1 has a second groove 20 located below the mounting cavity 15. A traction component 21 is movably mounted on the inner top wall of the second groove 20, extending into the mounting cavity 15 and fixedly connected to the right side of the slider 16. The traction component 21 includes a mounting shaft 211. The inner top wall of the second groove 20 is movably mounted with a mounting shaft 211 extending into the mounting cavity 15. A second circular hole is opened on the mounting block 1 between the inner top wall of the second groove 20 and the inner bottom wall of the mounting cavity 15. A third bearing is fixedly mounted inside the second circular hole. The mounting shaft 211 is rotatably connected to the mounting block 1 through the third bearing. A take-up roller 212 located on the right side of the slider 16 is fixedly mounted on the outer top of the mounting shaft 211. A traction rope 213 with one end fixedly connected to the right side of the slider 16 is wound around the outer side of the take-up roller 212. A second handwheel 214 located inside the second groove 20 is fixedly mounted on the bottom of the mounting shaft 211.

[0026] In use, the mounting block 1 can be fixedly connected to the reducer housing using bolts and fixing holes 2, thereby installing the mounting plate body 5. Then, the wave generator can be installed in the wave generator mounting hole 6 and fixedly connected to the motor's output shaft, allowing the motor to drive the wave generator to rotate for load operation. When maintenance or replacement of the mounting plate body 5 is required, the second handwheel 214 can be turned to rotate the mounting shaft 211 and the winding roller 212. The rotating roller 212 winds up the traction rope 213, causing the slider 16 and positioning block 18 to move to the right, thus positioning the block... 18 is moved out of the positioning groove 17, thereby releasing the position restriction on the fixing block 10. Then, the first handwheel 144 can be turned to drive the rotating shaft 141 and the drive gear 142 to rotate. In turn, the two driven gears 143 drive the two threaded rods 8 to rotate synchronously. During the rotation of the two threaded rods 8, the fixing block 10 will move downward, so that the fixing block 10 is moved out of the fixing groove 9, thereby releasing the fixation between the connecting block 4 and the mounting block 1. At this time, the mounting plate body 5 can be removed by pulling it forward without removing the bolts, which facilitates the maintenance or replacement of the mounting plate body 5.

[0027] In summary, the reducer mounting plate for the industrial robot joint rotates by turning the second handwheel 214, which drives the mounting shaft 211 and the take-up roller 212 to rotate. The take-up roller 212, during rotation, winds up the traction rope 213, thereby moving the slider 16 and the positioning block 18 to the right. This causes the positioning block 18 to move out of the positioning groove 17, releasing the positional restriction on the fixed block 10. Then, turning the first handwheel 144 rotates the rotating shaft 141 and the drive gear 142, which in turn drives the two threaded rods 8 to rotate synchronously via the two driven gears 143. During rotation, the two threaded rods 8 drive the fixed... Block 10 moves downwards to remove the fixing block 10 from the inside of the fixing groove 9, thereby releasing the fixation between the connecting block 4 and the mounting block 1. At this time, the mounting plate body 5 can be removed by pulling it forward without removing the bolts, thus achieving the purpose of easy disassembly. This facilitates the maintenance or replacement of the mounting plate body 5 and solves the problem that most existing reducer mounting plates are directly fixed to the reducer housing with bolts, which makes it inconvenient to disassemble the mounting plate during subsequent use, thus hindering maintenance or replacement and making it unsuitable for use.
