Description
Technical Field
[0001] The utility model relates to the technical field of testing devices, in particular to a quality inspection and testing device for a planetary gear reducer. Background Art
[0002] A planetary gear reducer is a mechanical transmission device, usually composed of planetary gears, a sun gear and a planet carrier. It realizes the deceleration of the high-speed rotation of the input shaft to the low-speed rotation of the output shaft through the meshing of the planetary gears on the planet carrier with external gears. This design provides high transmission efficiency and load-bearing capacity, and is suitable for industrial applications that require precise control and high torque output, such as machine tools, conveyors and lifting equipment, etc. During the production process of the planetary gear reducer, it is necessary to verify whether the performance of each planetary gear reducer meets the design requirements.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0038] Refer to Figures 1-3 , an embodiment provided by the present utility model: a quality inspection and testing device for a planetary gear reducer, including:
[0039] A frame 1, a support frame 2 is fixedly connected to the top of the frame 1, and the support frame 2 is used to provide support. A testing component is arranged on one side of the frame 1, and the testing component is used to test the reducer;
[0040] A fixing plate 3, the fixing plate 3 is fixedly connected to one side of the support frame 2, a ball seat 4 is rotatably connected inside the fixing plate 3, a cylinder 5 is fixedly connected to the top end of the ball seat 4, and an output end of the cylinder 5 is fixedly connected to a lever 6, and the lever 6 is used to apply pressure;
[0041] A fixing frame 7, the fixing frame 7 is fixedly connected to one side of the support frame 2, the lever 6 is rotatably connected inside the fixing frame 7, a connecting block 8 is fixedly connected to the bottom of one side of the lever 6, and the connecting block 8 is slidably connected inside the support frame 2;
[0042] A connecting rod 9, the connecting rod 9 is rotatably connected inside the connecting block 8, a rotating block 10 is rotatably connected to one side of the connecting rod 9, and the connecting rod 9 is used to connect the connecting block 8 and the rotating block 10;
[0043] A clamping block 11, the clamping block 11 is fixedly connected to the top of the rotating block 10, a rotating shaft 12 is fixedly connected inside the clamping block 11, the rotating shaft 12 is rotatably connected inside the support frame 2, and the clamping block 11 is used to clamp the reducer.
[0044] Specifically, when using this testing device, first place the reducer to be detected above the support frame 2. Then, drive the lever 6 to move through the output end of the cylinder 5. The lever 6 bears force during this process and rotates inside the fixed frame 7. At the same time, the movement of the lever 6 also drives the bottom of one side of the connecting block 8 to move inside the support frame 2. The function of the connecting block 8 is to transmit the moving force to the internally connected connecting rod 9 and guide it to rotate. Under the action of the force, the connecting rod 9 further drives the connected rotating block 10 to move. The movement of the rotating block 10 guides the top-connected clamping block 11 to move. The clamping block 11 drives the internally connected rotating shaft 12 to rotate inside the support frame 2 through the force. In this way, the clamping block 11 can accurately clamp on the outer wall of the reducer to achieve effective fixing and testing operations of the reducer.
[0045] Refer to Figure 1 、 Figure 4 and Figure 5 , the testing component includes a tester 13 and a test connector 14. The tester 13 is fixedly connected to one side of the frame 1. One end of the tester 13 is electrically connected to the test connector 14. The top of the frame 1 is fixedly connected to a fixed frame 15. The top of the fixed frame 15 is fixedly connected to a support frame 16. Inside the support frame 16, a turntable 17 is rotatably connected. The bottom end of the turntable 17 is fixedly connected to a connecting column 18. The bottom end of the connecting column 18 is fixedly connected to a handle 19. A limiting groove 20 is formed inside the turntable 17. A limiting post 21 is arranged inside the turntable 17. The limiting post 21 is slidably connected inside the limiting groove 20.
[0046] Specifically, after fixing, insert the test connector 14 into the reducer, and the cooperation between the tester 13 and the test connector 14 is used for testing. During the testing process, the operator can rotate the handle 19 to apply force to the connecting column 18 and guide it to rotate. The movement of the connecting column 18 is transmitted to the top-connected turntable 17, causing it to rotate inside the support frame 16. The limiting groove 20 provided inside the turntable 17 plays a key role. It guides the limiting post 21 to move along with the movement of the turntable 17, achieving the effect of movement transmission.
[0047] Refer to Figure 1 、 Figure 4 and Figure 5 , the top end of the limiting post 21 is fixedly connected to a sliding plate 22. A sliding groove 23 is formed inside the support frame 16. The sliding plate 22 is slidably connected inside the sliding groove 23. The top of the sliding groove 23 is fixedly connected to a limiting block 24.
[0048] Specifically, the movement of the limit post 21 drives the sliding plate 22 connected to the top to slide inside the chute 23. The movement of the sliding plate 22 further affects the limit block 24 connected to the top, enabling the limit block 24 to accurately fit on the outer wall of the test joint 14, ensuring that the test joint 14 can be effectively supported during the test, preventing it from accidentally falling off, and guaranteeing the safety and reliability of the test operation.
[0049] Working principle: When using this test device, first place the reducer to be detected above the support frame 2. Subsequently, the output end of the cylinder 5 drives the lever 6 to move. The lever 6 rotates inside the fixed frame 7 under force. At the same time, the lever 6 drives the connecting block 8 connected to the bottom on one side to move inside the support frame 2. The connecting block 8 drives the connecting rod 9 connected inside to rotate under force. The connecting rod 9 drives the rotating block 10 connected on one side to move. The rotating block 10 drives the clamping block 11 connected to the top to move. The clamping block 11 drives the rotating shaft 12 connected inside to rotate inside the support frame 2, thereby enabling the clamping block 11 to clamp on the outer wall of the reducer, achieving the effect of effectively fixing reducers of different sizes. After the fixing is completed, at this time, insert the test joint 14 into the reducer, and through the cooperation between the tester 13 and the test joint 14, test the reducer. During this process, the handle 19 can be rotated, and it drives the connecting column 18 to rotate under force. The connecting column 18 drives the turntable 17 connected to the top to rotate inside the support frame 16. The turntable 17 drives the limit post 21 to move through the limit groove 20 opened inside. The limit post 21 drives the sliding plate 22 connected to the top to slide inside the chute 23 under force. The sliding plate 22 drives the limit block 24 connected to the top to move under force, thereby enabling the limit block 24 to fit on the outer wall of the test joint 14, achieving the effect of providing effective support for the test joint 14 to prevent it from falling off.
