Description

Technical Field

[0001] The present invention relates to the technical field of planetary reducers, and in particular to a planetary reducer detection device. Background Art

[0002] Planetary gear reducer, also known as planetary speed reducer, is a planetary reduction gear device used to reduce the output speed of the prime mover and increase the output torque. Its function is to reduce the speed, increase the torque and reduce the rotational inertia ratio of the load motor under the premise of ensuring precise transmission. Planetary reducers are widely used in engineering machinery and equipment. In the production process of planetary reducers, it is necessary to test the actual precision of the speed reduction to ensure that the effectiveness of the produced planetary reducers meets expectations.

[0003] The existing detection methods for planetary reducers are still mostly manual detection. A detection motor and a torque sensor are connected to the input and output shaft of the planetary reducer respectively, and then the speed of the detection motor and the actual speed measured by the torque sensor are compared to judge the deceleration effect of the reduced machine under test. However, when facing planetary reducers of different models, it is often necessary to replace the corresponding coupling and then reconnect the detection motor, planetary reducer and torque sensor. This is not only time-consuming and labor-intensive, but also brings inconvenience to the actual storage of the detection equipment. For this reason, a planetary reducer detection device is proposed.

[0017] 1.

Then, the limiting inclined rods on both sides will reset under the elastic action of the locking spring, clamping the replacement module to prevent it from shaking up and down during the test process, affecting the test results;

[0020] 4.

[0023] 7. The present invention provides a friction-reducing slide plate so that the friction-reducing slide plate can slide along with the planetary reducer body, thereby reducing the relative sliding amount of the contact surface between the friction-reducing slide plate and the planetary reducer body, and reducing the wear of the input end and the output shaft end surface of the planetary reducer body.

[0040] like Figures 1 to 10As shown, a planetary reducer detection device includes a base 1, and a lifting platform 2 is fixedly installed on the top of the base 1. Figure 3 As shown, two symmetrically distributed clamping rails 3 are fixedly installed on the top of the lifting platform 2, and the same placement platform 4 is fixedly installed on the top of the side where the two clamping rails 3 are close to each other. A planetary reducer body 39 is placed on the top of the placement platform 4. A clamping slider 5 is driven and installed on the top of the clamping rails 3. A clamping claw 6 is fixedly installed on the top of the clamping slider 5. The two clamping claws 6 are symmetrically distributed on both sides of the planetary reducer body 39, as shown in FIG. Figure 2 As shown, two test benches 7 are fixedly installed on the top of the base 1, and the two test benches 7 are symmetrically distributed on both sides of the lifting platform 2. The same test assembly is arranged on the top of the two test benches 7, and the tops of the two test assemblies are respectively provided with a test motor 11 and a torque sensor 12, and the axis of the output shaft of the test motor 11 and the torsion shaft of the torque sensor 12 are consistent; specifically, when the planetary reducer detection device is in use, the planetary reducer body 39 is placed on the placement platform 4, and then the clamping electric rail 3 drives the clamping slider 5 to drive the clamping claw 6 to clamp the placement platform 4, and then the lifting platform 2 drives the placement platform 4 to lift upward, so that the planetary reducer body 39 is raised to the same height as the test motor 11 and the torque sensor 12, so that the input end and output end of the planetary reducer body 39 are aligned. The axis of the shaft is consistent with the output shaft of the test motor 11 and the axis of the torque shaft of the torque sensor 12. In this embodiment, the test motor 11 and the torque sensor 12 both have a power-off self-locking function, and a main control module can be used to control driving parts such as the lifting platform 2 and the placement platform 4. The model of the current planetary reducer body 39 to be tested can be input into the main control module. The main control module can call the data of the current planetary reducer body 39 from the database, which can not only be compared with the actual measured speed data to determine whether the deceleration effect of the current planetary reducer body 39 is qualified, but also can accurately control the movement of each driving part to avoid excessive movement of moving parts such as the clamping claw 6, resulting in damage to the planetary reducer body 39 due to excessive clamping force;

[0041] The test assembly is used to automatically connect the test motor 11, the torque sensor 12 and the planetary reducer body 39 of different models, and to test the deceleration effect of the planetary reducer body 39;

[0042] like Figure 4 , Figure 5 As shown, in this embodiment, the test assembly is actually divided into two parts, one of which is connected to the test motor 11 and the input test shaft 17, and the other is connected to the torque sensor 12 and the output test tube 18. All other structures remain the same, so Figure 6 , Figure 8 , Fig. 9Taking the torque sensor 12 and the output test tube 18 as examples, the test assembly includes two test rails 8 fixedly installed on the top of the two test benches 7, the test rails 8 are perpendicular to the clamping rails 3, the top of the test rails 8 are driven to install a test slider 9, the top of the test slider 9 is fixedly installed with a supporting frame 10, the two supporting frames 10 are symmetrically distributed, the test motor 11 and the torque sensor 12 are fixedly installed on the top of the two supporting frames 10, the top of the supporting frames 10 are fixedly installed with a transposition rail 13, the transposition rail 13 is perpendicular to the test slider 9, the top of the clamping rail 3 is driven to install a transposition slider 14, and the top of the transposition slider 14 is fixedly installed with an arrangement frame 15, as shown in FIG. Figure 6 As shown, a plurality of evenly distributed module racks 20 are slidably mounted on the arrangement rack 15, wherein the plurality of module racks 20 on one side are provided with input test shafts 17, and the plurality of module racks 20 on the other side are provided with output test tubes 18, the input test shaft 17 and the input end of the test motor 11 and the planetary reducer body 39 are located on the same side, and the output test tube 18 and the output shaft of the torque sensor 12 and the planetary reducer body 39 are located on the same side, as shown in FIG. Figure 8As shown, the ends of the input test shaft 17 and the output test tube 18 that are away from each other are fixedly installed with a docking tube 19, and one end of the docking tube 19 is provided with a cross slot. The output shaft of the test motor 11 and one end of the torsion shaft of the torque sensor 12 are both driven and connected with a cross transmission rod 16, and the cross transmission rod 16 is adapted to the cross slot. Spring frames 25 are provided on both sides of the module frame 20, and the spring frames 25 are fixedly installed on the side of the arrangement frame 15 close to the docking tube 19, and a surplus spring rod 26 is fixedly installed between the spring frame 25 and the module frame 20; specifically, by setting the test component, when the model of the planetary reducer body 39 to be tested is known, the transposition electric rails 13 on both sides will respectively drive the transposition slider 1 4 drives the two arrangement frames 15 to move horizontally, and moves the input test shaft 17 and the output test tube 18 corresponding to the model of the planetary reducer body 39 to the front of the test motor 11 and the torque sensor 12, and then the test electric rails 8 on both sides drive the test slider 9 and the supporting frame 10 to drive the test motor 11 and the torque sensor 12 to move toward the planetary reducer body 39 until the input test shaft 17 and the output test tube 18 contact the input end and the output shaft of the planetary reducer body 39 respectively. If the input test shaft 17 and the output test tube 18 cannot directly connect with the input end and the output shaft of the planetary reducer body 39, the test slider 9 continues to move to compress the residual spring rods 26 on both sides of the module frame 20, and the module frame 20 is arranged on the frame. 15, relative sliding occurs until the docking tube 19 docks with the cross transmission rod 16, and then the test motor 11 drives the input test shaft 17 to rotate slowly until the input test shaft 17 and the input end of the planetary reducer body 39 are in alignment. The input test shaft 17 will dock with the input end of the planetary reducer body 39 under the elastic action of the residual spring rod 26. Similarly, the test motor 11 drives the input end and output shaft of the planetary reducer body 39 to rotate synchronously, so that the output test tube 18 docks with the output shaft of the planetary reducer body 39. If the input test shaft 17, the output test tube 18 and the input end and output shaft of the planetary reducer body 39 can be directly docked, the test slider 9 continues to move, so that the two cross transmission rods 16 are docked with the docking tube 19 respectively. When the test motor 11, the planetary reducer body 39 and the torque sensor 12 are all docked, the test motor 11 can increase the speed, and then drive the torque shaft of the torque sensor 12 to decelerate and rotate through the cross transmission rod 16, the docking tube 19, the input test shaft 17, the planetary reducer body 39, the output test tube 18, another docking tube 19 and the cross transmission rod 16 in sequence, and then compare the speed of the output shaft of the test motor 11 with the speed of the torque shaft of the torque sensor 12 to measure the deceleration effect of the current planetary reducer body 39, realize the automatic docking of the test motor 11, the planetary reducer body 39 and the torque sensor 12, and automatically adapt to different models of planetary reducer bodies 39.

[0043] like Figure 6 , Fig. 9 As shown, a replacement module 21 is slidably inserted into the module rack 20, and a driven rotating ring 22 is rotatably installed on one side of the replacement module 21. The input test shaft 17 and the output test tube 18 are respectively fixedly installed inside the multiple driven rotating rings 22; specifically, by setting the replacement module 21, the input test shaft 17 and the output test tube 18 are placed on the arrangement rack 15 with the help of the replacement module 21. There can be multiple module racks 20 on the same arrangement rack 15, and each module rack 20 can be plugged with a replacement module 21 carrying input test shafts 17 and output test tubes 18 of different models. If the model of the planetary reducer body 39 to be tested is inconsistent with all the input test shafts 17 and output test tubes 18 stored on the arrangement rack 15, the replacement module 21 can be directly removed and replaced with the input test shaft 17 and output test tube 18 of the corresponding model, so that the replacement of the input test shaft 17 and the output test tube 18 is modularized, which not only expands the application scope of the detection device, but also reduces the difficulty of replacement.

[0044] like Figure 6 , Figure 7 As shown, two limiting slide grooves 23 are provided on both sides of the top of the module frame 20, and a limiting inclined rod 24 is slidably installed between the two limiting slide grooves 23 on the same side. The two limiting inclined rods 24 are distributed on both sides of the top of the replacement module 21. The inside of the limiting slide grooves 23 is provided with a locking spring 40, and the two ends of the locking spring 40 are respectively fixedly installed on the inner wall of the limiting slide groove 23 and the side wall of the limiting inclined rod 24; specifically, by setting the limiting inclined rod 24, the replacement module 21 can be inserted into When the module rack 20 is replaced, the bottom of the replacement module 21 will contact the tops of the two limiting inclined rods 24 and squeeze them apart, so that the limiting inclined rods 24 will shrink to the limiting slide grooves 23, and the replacement module 21 can be directly inserted into the module rack 20, and then the limiting inclined rods 24 on both sides will be reset under the elastic action of the locking springs 40, and the replacement module 21 will be clamped to prevent it from shaking up and down during the test and affecting the test results. When taking out the replacement module 21, it is only necessary to push open the limiting inclined rods 24 on both sides. The operation is simple and convenient.

[0045] like Figure 6 , Fig. 9As shown, a positioning rod 27 is fixedly installed on one side of the driven rotating ring 22 away from the docking tube 19, and a plurality of positioning frames 28 are fixedly installed on one side of the arrangement frame 15. The plurality of positioning rods 27 are respectively plugged into the plurality of positioning frames 28. In this embodiment, the relative length of the mutual plugging of the positioning rod 27 and the positioning frame 28 is greater than the spacing between the cross transmission rod 16 and the docking tube 19, and is much smaller than the plugging depth of the cross transmission rod 16 and the docking tube 19. The length of the output test tube 18 is greater than the maximum contraction distance of the margin spring rod 26. That is, when the input test shaft 17 or the output test tube 18 contacts the planetary reducer body 39 and drives the replacement module 21 to slide in the arrangement frame 15, before the positioning rod 27 is separated from the positioning frame 28, the docking sleeve 19 has been plugged into the cross transmission rod 16. After the positioning rod 27 is separated from the positioning frame 28, the cross transmission rod 16 still slides inside the docking sleeve 19 until the two are fully plugged in, and when the input test shaft 17 and the output test tube 18 are respectively connected to the planetary reducer body 39 under the elastic action of the residual spring rod 26, After the input end and output shaft of the planetary reducer 9 are plugged in, the positioning rod 27 and the positioning frame 28 are still in a disengaged state, and will not hinder the axial rotation of the input test shaft 17 and the output test tube 18; specifically, by setting the positioning rod 27, when the test motor 11 and the torque sensor 12 are not connected to the planetary reducer body 39, the positioning rod 27 and the positioning frame 28 are plugged in with each other, which plays an axial limiting role on the driven rotating ring 22 and the input test shaft 17 and the output test tube 18, so that all the input test shafts 17 and the output test tubes 18 can be axially limited. The test tube 18 always remains in alignment before docking, and the test motor 11 and torque sensor 12 with self-locking function will also remain aligned with the input test shaft 17 and the output test tube 18, so as to facilitate docking based on the current axial position of the input test shaft 17 and the output test tube 18. When the module frame 20 slides away from the arrangement frame 15, the positioning rod 27 and the positioning frame 28 will be disengaged synchronously, and the driven rotating ring 22 is no longer restricted, and can be driven by the test motor 11 to drive the planetary reducer body 39 to rotate.

[0046] like Figure 4 , Figure 5As shown, a transmission spring rod 29 is fixedly installed between the test motor 11, the torque sensor 12 and the two cross transmission rods 16, and a pressure sensor is arranged inside the transmission spring rod 29; specifically, by arranging the pressure sensor, when the test motor 11 and the torque sensor 12 are docked with the planetary reducer body 39, the input test shaft 17 and the output test tube 18 first contact the input end and the output shaft of the planetary reducer body 39. If they fail to dock, the pressure sensor inside the transmission spring rod 29 will sense the pressure generated by the contact between the input test shaft 17 and the input end of the planetary reducer body 39 through the cross transmission rod 16, the docking tube 19 and the input test shaft 17. When the pressure increases to a specified value as the test slider 9 moves, the test slider 9 stops moving, providing the test motor 11 with time to control the input test shaft 17 to rotate and dock with the input end of the planetary reducer body 39. Similarly, the first sensor on the other side can also reserve time for the docking of the output test tube 18 with the output shaft of the planetary reducer body 39.

[0047] like Figure 2 , Fig.10 As shown, two auxiliary slide rails 30 are fixedly installed on the top of the base 1, and the auxiliary slide rails 30 are perpendicular to the clamping electric rails 3. Auxiliary sliders 31 are slidably installed on the tops of the auxiliary slide rails 30. Auxiliary electric push rods 32 placed horizontally are fixedly installed on the tops of the ends of the two auxiliary slide rails 30 away from each other. Auxiliary push racks 33 are fixedly installed on the tops of the auxiliary sliders 31. The telescopic ends of the two auxiliary electric push rods 32 are respectively fixedly installed on the side walls of the auxiliary push racks 33, and the tops of the two auxiliary push racks 33 are fixedly installed with elastic telescopic push plates 34. Specifically, by setting the auxiliary push racks 33, when the planetary reducer body is moved After 39 is placed on the placement platform 4, the auxiliary push frames 33 on both sides will move along the auxiliary slide rails 30 driven by the auxiliary electric push rods 32 until the two elastic retractable push plates 34 respectively contact the end faces of the input end and the output shaft of the planetary reducer body 39, thereby pushing the planetary reducer body 39 to the middle position at the top of the placement platform 4, and then the clamping claws 6 on both sides push the planetary reducer body 39 to the middle position in another direction and clamp it, so that the elastic retractable push plates 34 and the clamping claws 6 cooperate with each other to achieve the initial positioning of the planetary reducer body 39, and then the auxiliary push frame 33 is reset to release the planetary reducer body 39.

[0048] like Fig.10As shown, a laterally placed wear-reducing slide plate 35 is slidably installed on one side of the two elastic telescopic push plates 34 that are close to each other. In this embodiment, the wear-reducing slide plate 35 can be made of soft materials such as rubber. Reset spring rods 36 are fixedly installed on both sides of the elastic telescopic push plates 34, and the telescopic ends of the two reset spring rods 36 are fixedly installed on both sides of the wear-reducing slide plate 35 respectively. Specifically, by setting the wear-reducing slide plate 35, in the process of the clamping claws 6 clamping the planetary reducer body 39, since the planetary reducer body 39 has been clamped by the elastic telescopic push plates 34 on both sides, the planetary reducer body 39 will slide relative to the elastic telescopic push plates 34. The setting of the wear-reducing slide plate 35 can enable the wear-reducing slide plate 35 to slide together with the planetary reducer body 39, reduce the relative sliding amount of the contact surface between the wear-reducing slide plate 35 and the planetary reducer body 39, and reduce the wear of the input end and the output shaft end face of the planetary reducer body 39. After the elastic telescopic push plate 34 is separated from the planetary reducer body 39, the wear-reducing slide plate 35 will be reset under the elastic action of the reset spring rod 36.

[0049] like Figure 3 As shown, a plurality of evenly distributed first semicircular chucks 37 are rotatably mounted on one side of the clamping claw 6 close to the planetary reducer body 39, and a plurality of evenly distributed second semicircular chucks 38 are rotatably mounted on one side of the plurality of first semicircular chucks 37 close to the planetary reducer body 39. In this embodiment, in addition to the first semicircular chucks 37 and the second semicircular chucks 38, semicircular chucks can be further added on the side wall of the second semicircular chuck 38 close to the planetary reducer body 39 to improve the clamping accuracy; specifically, by setting the first semicircular chucks The disk 37 and the second semicircular chuck 38 enable the multiple first semicircular chucks 37 and the second semicircular chucks 38 located on both sides to fit the shape of the planetary reducer body 39 and rotate under pressure when the two clamping claws 6 approach each other and clamp the planetary reducer body 39, thereby fitting tightly against the outer shell of the planetary reducer body 39, so that the clamping claws 6 can fit more closely to the planetary reducer body 39, effectively preventing the planetary reducer body 39 from being offset or misplaced, thereby adapting to planetary reducer bodies 39 of different models and structures.

[0050] In summary: before docking: place the planetary reducer body 39 on the placement platform 4, and the auxiliary push frames 33 on both sides will move along the auxiliary slide rails 30 under the drive of the auxiliary electric push rods 32 until the two elastic telescopic push plates 34 contact the end faces of the input end and the output shaft of the planetary reducer body 39 respectively, thereby pushing the planetary reducer body 39 to the middle position on the top of the placement platform 4, and then the clamping claws 6 on both sides push the planetary reducer body 39 to the middle position in another direction and clamp it, so that the elastic telescopic push plates 34 and the clamping claws 6 cooperate with each other to achieve the initial positioning of the planetary reducer body 39, and then the auxiliary push frame 33 is reset, the planetary reducer body 39 is released, and then the lifting platform 2 The driving placement platform 4 is lifted upward, so that the planetary reducer body 39 is raised to the same height as the test motor 11 and the torque sensor 12, so that the axis of the input end and the output shaft of the planetary reducer body 39 are consistent with the output shaft of the test motor 11 and the axis of the torsion shaft of the torque sensor 12. At this time, the positioning rod 27 and the positioning frame 28 are plugged into each other, which plays an axial limit role for the driven rotating ring 22 and the input test shaft 17 and the output test tube 18, so that all the input test shafts 17 and the output test tubes 18 always maintain the alignment state before docking, and the test motor 11 and the torque sensor 12 with self-locking function will also maintain alignment with the input test shaft 17 and the output test tube 18;

[0051] During docking: When the model of the planetary reducer body 39 to be tested is known, the transposition rails 13 on both sides will respectively drive the transposition slider 14 to drive the two arrangement frames 15 to move horizontally, and move the input test shaft 17 and the output test tube 18 corresponding to the model of the planetary reducer body 39 to the front of the test motor 11 and the torque sensor 12, and then the test rails 8 on both sides drive the test slider 9 and the supporting frame 10 to drive the test motor 11 and the torque sensor 12 to move toward the planetary reducer body 39 until the input test shaft 17 and the output test tube 18 are in contact with the row respectively. The input end and output shaft of the planetary reducer body 39, if the input test shaft 17 and the output test tube 18 cannot be directly connected to the input end and the output shaft of the planetary reducer body 39, the test slider 9 continues to move to compress the residual spring rods 26 on both sides of the module frame 20, and the module frame 20 slides relatively on the arrangement frame 15 until the docking tube 19 docks with the cross transmission rod 16, the positioning rod 27 and the positioning frame 28 will be synchronously disengaged, the driven rotating ring 22 is no longer restricted, and the pressure sensor inside the transmission spring rod 29 will be connected through the cross transmission rod 16, the docking tube 19 and the input force test tube 18. The test shaft 17 senses the pressure generated by the contact between the input test shaft 17 and the input end of the planetary reducer body 39. When the pressure increases to a specified value as the test slider 9 moves, the test slider 9 stops moving, providing the test motor 11 with time to control the rotation of the input test shaft 17 and dock with the input end of the planetary reducer body 39. Then the test motor 11 drives the input test shaft 17 to rotate slowly until the input test shaft 17 and the input end of the planetary reducer body 39 are in alignment. The input test shaft 17 will align with the input end of the planetary reducer body 39 under the elastic action of the residual spring rod 26. The input end of the planetary reducer body 39 is docked. Similarly, the first sensor on the other side can also reserve time for the docking of the output test tube 18 with the output shaft of the planetary reducer body 39. The test motor 11 then drives the input end and output shaft of the planetary reducer body 39 to rotate synchronously, so that the output test tube 18 is docked with the output shaft of the planetary reducer body 39. If the input test shaft 17, the output test tube 18 and the input end and output shaft of the planetary reducer body 39 can be directly docked, the test slider 9 continues to move to dock the two cross transmission rods 16 with the docking tube 19 respectively;

[0052] After docking: When the test motor 11, the planetary reducer body 39 and the torque sensor 12 have all been docked, the test motor 11 can increase the speed, and then drive the torque shaft of the torque sensor 12 to decelerate and rotate through the cross transmission rod 16, the docking tube 19, the input test shaft 17, the planetary reducer body 39, the output test tube 18, another docking tube 19 and the cross transmission rod 16 in sequence, and then compare the speed of the output shaft of the test motor 11 with the speed of the torque shaft of the torque sensor 12 to measure the deceleration effect of the current planetary reducer body 39, realize the automatic docking of the test motor 11, the planetary reducer body 39 and the torque sensor 12, and can automatically adapt to different models of planetary reducer bodies 39.
