Description

Technical Field

[0001] The utility model relates to the technical field of reducer detection, in particular to a planetary cycloid gear reducer detection device. Background Technique

[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 the prime mover and the working machine, playing a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.

[0003] After retrieval, the Chinese patent publication number: CN218444458U discloses a reducer detection device, including a detection table, a driving motor, a load device, and a fixed seat. A lifting cavity is opened inside the fixed seat, and two pairs of hydraulic lifting cylinders are arranged inside the lifting cavity. An adjustment cavity is opened at the bottom end of the lifting cavity inside the fixed seat, and a driving threaded rod and a driven threaded rod are rotatably connected inside the adjustment cavity. A pair of sliding blocks are threadedly connected to the outer walls of the driving threaded rod and the driven threaded rod. The bottom ends of the two pairs of hydraulic lifting cylinders all pass through the lifting cavity and are fixedly connected to the top ends of the sliding blocks. By driving the threaded rod to rotate through the adjustment motor, and then driving the mounting seat to slide through the hydraulic lifting cylinder, the position of the mounting seat can be adjusted. At the same time, the height of the mounting seat can be adjusted by the lifting of the hydraulic lifting cylinder, so as to fix reducers of different sizes and heights, facilitating the detection of various reducers. This practical detection installation uses the existing coupling plug-in connection, but during long-term rotation, there may be a relatively unstable loosening phenomenon between the connecting shaft and the detector, thus easily causing problems with detection value deviation. Therefore, we have designed a new planetary cycloid gear reducer detection device. Content of the Utility Model

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 - 6, in the embodiment of the present utility model, a planetary cycloid gear reducer detection device includes a working platform 1, a planetary reducer 2 and a driving motor 7. A torque detector 5 is arranged in the middle of the top of the working platform 1. Two clamping assemblies 6 are arranged on the top of the working platform 1. An adjustment assembly 4 is arranged in the middle of the inside of the working platform 1. Limiting holes 8 are opened at the output ends of the planetary reducer 2 and the driving motor 7.

A joint groove 11 is arranged inside the joint head 10. An activity groove 12 is arranged on the inner side surface of the joint head 10. A limiting block 14 is slidably connected inside the activity groove 12. A connecting rod 13 is fixedly connected to the middle of the top end of the limiting block 14. A spring 15 is arranged on the outer wall of the connecting rod 13. One end of the spring 15 is connected to the inner top surface of the activity groove 12, and the other end of the spring 15 is connected to the top surface of the outer wall of the limiting block 14. The top end of the connecting rod 13 penetrates through the outer wall of the joint head 10 and is rotatably connected with an auxiliary block 16. Auxiliary ear plates 21 are fixedly connected to both sides of the outer wall of the auxiliary block 16.

[0026] During specific implementation, the required planetary reducer 2 and driving motor 7 to be detected are clamped through the arrangement of the clamping assembly 6. Through the arrangement of the slide rail 22 and the slider 23, the clamped planetary reducer 2 and driving motor 7 are moved to both sides of the corresponding joint head 10 of the torque detector 5. Then, the adjustment assembly 4 is used to adjust the torque detector 5 to align with the output end of one side of the planetary reducer 2. Then, the auxiliary block 16 and the auxiliary ear plate 21 arranged on the joint head 10 are pulled, so that the limiting block 14 is driven by the connecting rod 13 fixed to the auxiliary block 16 to enter the activity groove 12. Under the action of the slide rail 22 and the slider 23, the output ends of the planetary reducer 2 and the driving motor 7 are respectively inserted into the joint groove 11 of the corresponding joint head 10. The pulled auxiliary block 16 is released, and then under the action of the spring 15, the limiting block 14 is clamped into the limiting hole 8 on the adjusted output end, so that the installation is completed.

An internal fitting groove 18 is arranged in the middle of the inside of the sleeve 17. A fitting groove 19 corresponding to the fitting block 20 is opened on the top surface of the sleeve 17.

[0029] During specific implementation, when the limit block 14 is stuck in the limit hole 8 on the output end, by rotating the auxiliary block 16, the fitting block 20 enters the built-in fitting groove 18 through the fitting groove 19 provided on the sleeve 17. Thus, during rotation detection, the auxiliary block 16 does not drive the connecting rod 13 to swing outwards, preferably avoiding the limit block 14 from detaching from the limit hole 8. The fitting block 20 and the built-in fitting groove 18 are tightly fitted, further strengthening the stability between the limit block 14 and the connecting rod 13, and also preferably achieving the purpose of being easy to disassemble and assemble with good fixing effect.

Through the cooperation between the second bevel gear 47 and the first bevel gear 44, the first bevel gear 44 rotates inside the hollow column 41. When the first bevel gear 44 operates, the lead screw 45 threadedly connected to its inside moves up and down. Then, the torque detector 5 fixed on the receiving plate 24 together with the lead screw 45 moves up and down for adjustment, thus preferably cooperating with the clamping assembly 6 for use. The connecting ring frame 46 provided supports the second bevel gear 47.

Then, by starting the servo motor II 63, the servo motor II 63 drives the bidirectional screw 64 to rotate through the connecting shaft, so that the movable blocks 65 threadedly connected to the bidirectional screw 64 drive the clamping blocks 67 through the support frames 66 to clamp the planetary reducer 2 or the driving motor 7. It can be adjusted to a certain extent according to the size of the clamped object, so as to facilitate the replacement and detection of planetary reducers 2 and driving motors 7 of different sizes.
