[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear and 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, and plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.

[0003] A patent with publication number CN108519230A discloses a device for detecting the rotational accuracy of a harmonic reducer. The device includes a base, a loading mechanism, a torque sensor, an input grating, an output grating, a drive servo motor, and a clamping mechanism. The base has double guide rails, on which a longitudinal adjustment mechanism that can slide relative to the reducer is mounted. The longitudinal adjustment mechanism also has a lateral adjustment mechanism that can slide relative to the reducer. The drive servo motor is mounted on the lateral adjustment mechanism. The drive servo motor is connected to the input end of the harmonic reducer via the input grating. The output end of the harmonic reducer is connected to the output grating and the loading mechanism via the torque sensor. The harmonic reducer is fixed by the clamping mechanism. Using this solution, the rotational accuracy of the harmonic reducer can be detected more accurately.

[0004] Existing speed reducers are quite heavy, and during testing, they are lifted by cranes. However, the cranes are connected by ropes, which makes the speed reducers prone to swaying during lifting. Moreover, the speed reducers are heavy, and the inertia generated when they sway is large, which can cause injury to employees. In addition, it is difficult to dock the swaying speed reducer with the detector. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the reducer under swing is not easy to dock with the detector in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a rotary reducer rotation angle detection device, including an overlapping support frame and a shock-absorbing plate detachably installed on the top surface of the overlapping support frame, a U-shaped support frame detachably installed on the top surface of the shock-absorbing plate, a reducer movably sleeved on the inner wall of the U-shaped support frame, vertical grooves opened on the inner walls of both sides of the U-shaped support frame, a second motor fixedly installed on the inner wall of the vertical groove, a second slider movably sleeved on the outer surface of the output end of the second motor, and a first motor fixedly installed on the top surface of the shock-absorbing plate and at the two side edges.

[0007] In one embodiment of the present invention, a recessed groove is provided on the top surface of the shock-absorbing platform and at the two side edges, and the motor is located on the inner wall of the recessed groove.

[0008] In one embodiment of this utility model, a slider is threadedly and movably sleeved on the outer surface of the output end of the motor, and a motor is fixedly mounted on the top surface of the slider.

[0009] In one embodiment of this utility model, the output end of the motor is fixedly connected to the bottom surface of the U-shaped support frame, and overlapping support plates are fixedly connected to the inner walls on both sides of the U-shaped support frame.

[0010] In one embodiment of this utility model, the overlapping support plate is positioned at the edge of the bottom opening of the vertical groove, and a snap-fit ​​sleeve is fixedly installed on the inner wall of the second slider.

[0011] In one embodiment of the present invention, the outer surface of the reducer is movably sleeved on the inner wall of the snap-fit ​​housing, and the inner walls on both sides of the snap-fit ​​housing are provided with recessed grooves II, and trapezoidal elastic strips are fixedly connected to the inner wall of the recessed grooves II.

[0012] In one embodiment of the present invention, a fitting anti-slip plate is fixedly connected to the outer surface of the trapezoidal elastic strip and is movably sleeved on the inner wall of the recessed groove. An inclined groove is provided on the top inner wall of the fitting anti-slip plate.

[0013] In one embodiment of the present invention, a support plate is fixedly installed on both sides of the overlapping support frame, a hydraulic buffer pump is fixedly installed on the top surface of the support plate, a fixed sleeve is provided on the top outer surface of the hydraulic buffer pump, and the outer surface of the fixed sleeve is fixedly installed on the outer surface of the shock-absorbing platform.

[0014] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0015] The present invention discloses a rotary reducer rotation angle detection device. After the reducer is snapped and fixed, it moves in conjunction with the overlapping support frame. When the side of the overlapping support frame moves to the output end surface of the detector, it rotates in conjunction with motor three, so that the output end of the reducer faces the detector. It also rotates in conjunction with motor one inside the recessed groove one, and causes slider one on the outer surface of the output end of motor one to move laterally. The left and right lateral movement of slider one is used to adjust the position of the reducer, so that the reducer can be adjusted in position with the detection head of the detection device.

[0016] The present invention discloses a rotary reducer rotation angle detection device. After the position of motor one is adjusted, it works in conjunction with motor two on the inner wall of the vertical groove to rotate, causing slider two to move up and down under the push of motor two. When the position of the reducer moves to the horizontal position of the detector, the lifting and lowering stops, and the output end of the reducer is connected to the interface of the detector. The detector detects the rotation angle of the reducer, achieving the effect of using motor two, motor one and motor three to move the reducer at multiple angles and to adjust the position of the reducer.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1 - Figure 5As shown, this utility model discloses a rotary reducer rotation angle detection device, including an overlapping support frame 11 and a shock-absorbing plate 12 detachably mounted on the top surface of the overlapping support frame 11, a U-shaped support frame 14 detachably mounted on the top surface of the shock-absorbing plate 12, a reducer 15 movably sleeved on the inner wall of the U-shaped support frame 14, vertical grooves 141 formed on the inner walls of both sides of the U-shaped support frame 14, a second motor 142 fixedly mounted on the inner wall of the vertical grooves 141, a second slider 143 threadedly sleeved on the outer surface of the output end of the second motor 142, a first motor 122 fixedly mounted on the top surface of the shock-absorbing plate 12 at its two edge positions, and a recessed groove 121 formed on the top surface of the shock-absorbing plate 12 at its two edge positions, with the first motor 122 positioned within the recessed groove 121. On the inner wall, a slider 123 is threadedly fitted onto the outer surface of the output end of motor 122. Motor 3 124 is fixedly installed on the top surface of slider 123. The output end of motor 3 124 is fixedly connected to the bottom surface of U-shaped support frame 14. Overlapping support plates 145 are fixedly connected to the inner walls of both sides of U-shaped support frame 14. The position of overlapping support plates 145 is set at the edge of the bottom opening of vertical groove 141. A snap-fit ​​sleeve 144 is fixedly installed on the inner wall of slider 2 143. Support plates 111 are fixedly installed on both sides of overlapping support frame 11. A hydraulic buffer pump 112 is fixedly installed on the top surface of support plate 111. A fixed sleeve 113 is provided on the top outer surface of hydraulic buffer pump 112. The outer surface of fixed sleeve 113 is fixedly installed on the outer surface of shock-absorbing platform 12.

[0026] After the position of motor 122 is adjusted, it rotates in conjunction with motor 142 on the inner wall of the vertical groove 141, causing slider 143 to move up and down under the push of motor 142. When the position of reducer 15 moves to the horizontal position of the detector, the lifting stops, and the output end of reducer 15 is connected to the interface of the detector. The detector detects the rotation angle of reducer 15, achieving the effect of multi-angle movement of reducer 15 using motor 142, motor 122 and motor 124, and position adjustment of reducer 15. This avoids the problem of excessively heavy reducers requiring a crane to lift, and the inability to effectively adjust the position of a swaying reducer, which can also cause excessive shaking.

[0027] After the reducer 15 is snapped in place, it moves in conjunction with the overlapping support frame 11. When the side of the overlapping support frame 11 moves to the output end surface of the detector, it rotates in conjunction with the motor 124, so that the output end of the reducer 15 faces the detector. It also rotates in conjunction with the motor 122 inside the recessed groove 121, causing the slider 123 on the outer surface of the output end of the motor 122 to move laterally. The left and right lateral movement of the slider 123 is used to adjust the position of the reducer 15, so that the reducer 15 can be adjusted in position with the detection head of the detection device.

[0028] Reference Figure 1 - Figure 2 and Figure 4 - Figure 5 As shown, in one embodiment of the present invention, the outer surface of the reducer 15 is movably sleeved on the inner wall of the snap-fit ​​sleeve 144. The inner walls on both sides of the snap-fit ​​sleeve 144 are provided with recessed grooves a2. A trapezoidal elastic strip a2 is fixedly connected to the inner wall of the recessed groove a2. A sliding anti-slip plate a3 is movably sleeved on the inner wall of the recessed groove a1. A slanted groove a4 is provided on the top inner wall of the sliding anti-slip plate a3.

[0029] The reducer 15 is attached to the inner wall of the snap-fit ​​sleeve 144. At this time, the inclined groove a4 on the top surface of the anti-slip plate a3 guides the bottom surface of the reducer 15. When the reducer 15 is snapped into the snap-fit ​​sleeve 144, the trapezoidal elastic strips a2 on both sides of the inner wall of the snap-fit ​​sleeve 144 push the anti-slip plate a3 with elastic force, so that the anti-slip plate a3 is tightly attached to the outer surface of the reducer 15, and the position of the reducer 15 is limited.

[0030] Working principle: After the reducer 15 is snapped in place, it moves in conjunction with the overlapping support frame 11. When the side of the overlapping support frame 11 moves to the output end surface of the detector, it rotates in conjunction with the motor 124, so that the output end of the reducer 15 faces the detector. It also rotates in conjunction with the motor 122 inside the recessed groove 121, causing the slider 123 on the outer surface of the output end of the motor 122 to move laterally. The left and right lateral movement of the slider 123 is used to adjust the position of the reducer 15, so that the reducer 15 can be adjusted in position with the detection head of the detection device.

[0031] After the position of motor 122 is adjusted, it rotates in conjunction with motor 142 on the inner wall of the vertical groove 141, causing slider 143 to move up and down under the push of motor 142. When the position of reducer 15 moves to the horizontal position of the detector, it stops lifting and lowering, and the output end of reducer 15 is connected to the interface of the detector. The detector detects the rotation angle of reducer 15, thus achieving the effect of using motor 142, motor 122 and motor 124 to move reducer 15 at multiple angles and adjust the position of reducer 15.

[0032] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
