Description

[0001] The present application relates to the field of motor technology, and in particular to a motor reduction box testing device. Background Art

[0002] With the development of technology, electronically controlled or intelligently controlled home products are increasingly being adopted in daily life to facilitate various aspects of daily life. In smart home products, such as electric clothes dryers and electric telescopic racks, the drive unit typically utilizes a motor with a reduction gearbox. The motor outputs torque, which is then decelerated by the reduction gearbox to increase the torque output, ensuring effective driving of the actuator.

[0003] Currently, during the production and processing of motors and reducers, it is necessary to test the reduction ratio of the motor reducer gear set and the assembly direction of the gear structure. In the existing technology, when testing the motor reducer, the reducer needs to be assembled on the test device to meet the testing requirements of the gear set inside the reducer.

[0004] However, this approach requires first creating a mold for the gearbox housing, placing the gear set inside the housing, and then placing the housing in a test fixture to perform the corresponding gearbox performance test. This setup only matches gear sets with specific reduction ratios and assembly orientations. Testing gear sets with different reduction ratios requires re-molding the gearbox housing, which prolongs the development cycle and increases overall costs, hindering testing efficiency and cost control for motor-gearbox systems.

[0018] Furthermore, the load lower groove is an arc groove, the front and rear side surfaces of the lower slider are arc surfaces that fit with the inner side wall of the load lower groove, and the sliding clamping seat is arranged inside the area surrounded by the arc groove of the load lower groove.

[0019] Furthermore, a second connecting hole is provided on the side wall of the load slide corresponding to the lower slider, and a second locking hole is provided on the lower slider corresponding to the second connecting hole.

[0044] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0046] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0047] In order to solve the problem in the prior art that when testing the gear set of the reduction gear box, it is necessary to first open the mold of the reduction gear box shell and set the gear set in the reduction gear box shell for testing, which makes it impossible to meet the testing requirements of different gear sets, and thus causes high testing costs and difficulty in improving testing efficiency. The present application provides a motor reduction gear box testing device, which can directly set the worm gear in the reduction gear box on a sliding clamping seat for testing without the need to open the mold of the shell, and adjust the distance between the worm gear and the output end of the driving mechanism through the sliding clamping seat to adapt to the testing requirements of worm gears with different reduction ratios, avoiding the situation in the prior art where it is necessary to re-open the mold of the shell according to worm gears with different reduction ratios, resulting in high testing costs and low testing efficiency.

[0048] See also Figure 1 、 Figure 2 ,as well as Figure 3 A motor reduction box test device includes: a drive mechanism 2, a sliding clamping seat 3, and a load module 4, wherein:

[0049] The driving mechanism 2 is arranged on the base 1 and has its output end facing the direction of the sliding clamping base 3;

[0050] The sliding clamping seat 3 includes a worm gear slot 31 and two sets of worm gear sliders 32. The worm gear slot 31 and the output end of the driving mechanism 2 are spatially perpendicular to each other. The worm gear sliders 32 are movably embedded in the worm gear slot 31 and move along the worm gear slot 31. The top of the worm gear slider 32 is movably equipped with a worm gear 5, which is meshed with the output end of the driving mechanism 2 for transmission.

[0051] The load module 4 is arranged beside the sliding clamping seat 3 and is engaged with the worm gear 5 arranged on the top of the worm gear slider 32 for transmission.

[0052] When the motor's reduction gearbox system needs to be tested, the corresponding worm gear 5 samples can be made first, and the worm gear 5 can be placed on the two sets of worm gear sliders 32 on the sliding clamping seat 3, so that the pin 323 on the top of the worm gear slider 32 passes through the axial hole of the worm gear 5, ensuring that the worm gear 5 can rotate on the top of the worm gear slider 32. Then push the worm gear slider 32 so that the worm gear sliders 32 on both sides move along the worm gear slot 31, changing the relative position between the worm gear slider 32 and the output end of the drive mechanism 2. Move the worm gear sliders 32 on both sides to the side of the output end of the drive mechanism 2, and make the worm gear 5 mounted on the top of the worm gear slider 32 engage with the output end of the drive mechanism 2 for transmission.

[0053] In order to ensure the stability of the clothes drying rod during the lifting process, the output motor of the clothes drying machine is usually connected to a reduction gearbox on both ends. Therefore, during testing, it is generally necessary to test the reduction gearbox system on both ends separately. In the embodiment provided by the present application, a worm gear slider 32 is provided on both sides of the worm gear slide 31, so that the worm gear 5 to be tested can be respectively set on the worm gear slider 32. Therefore, during the test, the worm gear 5 on the worm gear slider 32 on both sides is meshed with the output end of the drive mechanism 2, thereby testing the two sets of worm gears 5 at the same time, effectively improving the overall test efficiency. At the same time, when the drive mechanism 2 drives the worm gears 5 on the two sets of worm gear sliders 32 to rotate, the driving torque received by the two sets of worm gears 5 is guaranteed to be the same, thereby ensuring the stability of the test effect of the two sets of worm gears 5, effectively ensuring the authenticity and reliability of the test results, and avoiding the situation where the test results are biased due to the worm gears 5 of the two reduction gearboxes being tested separately during the later adjustment.

[0054] In the embodiment provided in the present application, the worm gear slider 32 can move along the worm gear slot 31, so that the relative distance between the worm gear slider 32 and the output end of the driving mechanism 2 changes. This setting method can facilitate the engagement and disassembly between the worm gear 5 rotatably set on the top of the worm gear slider 32 and the output end of the driving mechanism 2, thereby meeting the detection and calculation of parameters such as the load performance of the worm gear 5 of the motor reducer system. At the same time, when testing the worm gear 5 configured in the motor reducer system of different specifications and models, or when testing the worm gear 5 that has been replaced before and after in the same motor reducer system during the proofing stage, the worm gear slider 32 can be pushed to move the worm gear slider 32 along the worm gear slot 31, so that the worm gear 5 set on the worm gear slider 32 is adjusted to a relative position for effective meshing transmission with the output end of the drive mechanism 2, so as to adapt to the corresponding testing requirements of the worm gear 5 in the motor reducer system of different specifications and models, or the worm gear 5 with different reduction ratios, and avoid the need to separately open the mold of the reducer housing when testing different worm gears 5, effectively reducing the time required for the overall testing process that is not related to the actual testing work, and can reduce the cost expenditure caused by mold opening, greatly shortening the development cycle and reducing development costs.

[0055] In some embodiments, the outer dimensions of the worm gear slider 32 are larger than the width of the worm gear slot 31. A sliding insert 322 is provided at the bottom of the worm gear slider 32, corresponding to the worm gear slot 31, and is embedded in the worm gear slot 31. By embedding the sliding insert 322 in the worm gear slot 31 and allowing it to move along the worm gear slot 31, the relative position between the worm gear slider 32 and the worm gear slot 31 can be changed by pushing the worm gear slider 32, thereby adjusting the position of the worm gear 5 on the pin 323 mounted on the top of the worm gear slider 32. By setting the outer dimensions of the worm gear slider 32 larger than the width of the worm gear slot 31, while adjusting the position of the worm gear 5, the portion of the worm gear slider 32 that extends beyond the worm gear slot 31 contacts the upper surface of the worm gear slot 31, thereby providing fore-aft support for the entire structure of the worm gear slider 32, effectively preventing the worm gear slider 32 from deflecting in the fore-aft direction due to external forces. At the same time, the portion of the worm gear slider 32 that extends beyond the worm gear slot 31 limits the top opening of the worm gear slot 31. Therefore, when the worm gear slider 32 tilts toward either side, the portion that extends beyond the worm gear slider 32 contacts the upper surface of the worm gear slot 31, thereby providing a limit to prevent the worm gear slider 32 from tipping over. In summary, by configuring the main portion of the worm gear slider 32 to be larger than the width of the worm gear slot 31, an effective limit is provided between the worm gear slider 32 and the worm gear slot 31, so that during the entire process of the worm gear slider 32 moving along the worm gear slot 31, the worm gear slider 32 and the worm gear 5 at the top remain in a relatively stable state, thereby meeting the requirements for testing the worm gear 5.

[0056] In some embodiments, a first connecting hole 311 is provided on the side wall of the worm gear groove 31 corresponding to the sliding insert 322, and a first locking hole 321 is provided on the sliding insert 322 of the worm gear slider 32 corresponding to the first connecting hole 311. The worm gear slider 32 is fixed to the worm gear groove 31 by a locking screw that passes through the first connecting hole 311 and the first locking hole 321 in sequence and locks them.

[0057] The worm gear slider 32 is pushed so that the worm gear slider 32 moves along the worm gear slot 31, and the relative position between the first locking hole 321 and the first connecting hole 311 changes. After the worm gear slider 32 is adjusted to the selected position, the first locking hole 321 is aligned with the first connecting hole 311, and a locking screw is taken through the first connecting hole 311 and the first locking hole 321 to fix the relative position between the worm gear slider 32 and the worm gear slot 31. This prevents the worm gear slider 32 from being subjected to force or vibration and moving away from the drive mechanism 2 when the drive mechanism 2 is started to drive the worm wheel 5 on the worm gear slider 32. This seriously affects the torque output of the drive mechanism 2 to the worm wheel 5 on the worm gear slider 32.

[0058] In some optional embodiments, the first connection holes 311 are through holes or threaded holes that are evenly distributed.

[0059] When the first connecting hole 311 is a through hole, after the worm gear slider 32 is pushed to move to the corresponding setting position, the first locking hole 321 on the worm gear slider 32 matches the position of the corresponding first connecting hole 311. The locking screw passes through the first connecting hole 311 and the first locking hole 321 to fix the relative position between the worm gear slider 32 and the worm gear slot 31, thereby ensuring that when the drive mechanism 2 engages the worm gear 5, the relative position between the worm gear 5 and the output end of the drive mechanism 2 is stable and reliable. In some optional embodiments, a pin is used instead of the locking screw, and the pin is passed through the first connecting hole 311 and the first locking hole 321 to limit and fix the worm gear slider 32 and the worm gear slot 31, thereby ensuring the stability of the connection and fixing state between the worm gear slider 32 and the worm gear slot 31, reducing the tightening operation of the locking screw, and improving operating efficiency.

[0060] When the first connecting hole 311 is a threaded hole, after the worm gear slider 32 is pushed to the corresponding setting position, the first locking hole 321 on the worm gear slider 32 matches the position of the corresponding first connecting hole 311. The locking screw passes through the first connecting hole 311 and the first locking hole 321 to fix the relative position between the worm gear slider 32 and the worm gear slot 31, thereby ensuring that when the drive mechanism 2 engages the worm gear 5, the relative position between the worm gear 5 and the output end of the drive mechanism 2 is stable and reliable. When the locking screw passes through the threaded hole of the first connecting hole 311, the locking screw is fixed to the first connecting hole 311 by tightening the thread. At the same time, the end of the locking screw extends into the first locking hole 321 of the worm gear slider 32, thereby limiting the movement of the worm gear slider 32 and fixing the relative position between the worm gear slider 32 and the worm gear slot 31.

[0061] The first connecting hole 311 is a bar hole distributed along the direction of the worm gear slot 31. A locking screw passes through the bar hole serving as the first connecting hole 311 and is screwed into the first locking hole 321 of the worm gear slider 32. As the worm gear slider 32 moves in the worm gear slot 31, the locking screw moves synchronously in the bar hole. When the worm gear slider 32 is moved into position, the locking screw is tightened so that the end of the locking screw is pressed against the outer wall of the worm gear slot 31. The worm gear slider 32 is then pulled toward the worm gear slot 31, thereby locking the side wall of the worm gear slot 31 through the end of the locking screw and the worm gear slider 32. This fixes the relative position between the worm gear slot 31 and the worm gear slider 32, thereby ensuring the stability of the connection and fixed state between the worm gear slider 32 and the worm gear slot 31, reducing the tightening operation of the locking screw, and improving operating efficiency.

[0062] In some embodiments, the load module 4 includes: a load lower slide chute, a load upper slide chute 42, a load component 43, and a detection component 44, wherein:

[0063] The load-down slide groove is provided on the pedestal 1 and is located beside the worm gear slide groove 31 and distributed along the left and right directions. The lower slider 411 is movably embedded in the load-down slide groove.

[0064] The load upper slide 42 has a bottom surface connected to the lower slider 411 and forms an angle with the load lower slide. The upper slider 421 is movably embedded in the load upper slide 42.

[0065] The load assembly 43 is connected to the upper slider 421 at the bottom and meshes with the worm gear 5 at the top;

[0066] The detection component 44 is disposed on the base 1 , and the detection end of the detection component 44 faces the load component 43 .

[0067] When assembling the worm gear 5 and adjusting the position of the worm gear slider 32, by pushing the load upper slide groove 42, the lower slide block 411 connected to the bottom of the load upper slide groove 42 moves along the load upper slide groove. At the same time, the load component 43 can be pushed to make the upper slide block 421 connected to the bottom of the load component 43 move along the load upper slide groove 42, so as to adjust the position of the load component 43 from different directions, so that the load component 43 can engage with the worm gear 5 on the worm gear slider 32, and then transmit the output torque applied to the worm gear 5 by the driving mechanism 2 to the load component 43, and then detect and identify the changes caused by the force on the load component 43 through the detection component 44, and obtain corresponding load change data, thereby meeting the requirements for obtaining and calculating the performance parameters of the worm gear 5 and completing the detection work of the worm gear 5 of the motor reducer system.

[0068] In the embodiment provided in the present application, the load sliding grooves are distributed along the left and right directions, and the relative distance between the load assembly 43 and the worm wheel 5 on the worm gear slider 32 in the X-axis direction can be adjusted. In some optional embodiments, the angle formed between the load upper groove 42 and the load lower groove is 90°, so that the relative distance between the load assembly 43 and the worm wheel 5 on the worm gear slider 32 in the Y-axis direction can be adjusted, thereby cooperating with the adjustment of the lower slider 411 in the load sliding groove to achieve effective meshing transmission with the worm wheel 5. In some optional embodiments, the angle formed between the load upper groove 42 and the load lower groove is an acute angle. Therefore, when the relative distance between the load assembly 43 and the worm wheel 5 on the worm gear slider 32 in the Y-axis direction is adjusted by the upper slider 421, the distance in the X-axis direction will also be fine-tuned accordingly, thereby pressing the load assembly 43 against the worm wheel 5 and effectively meshing transmission with the worm wheel 5 to ensure a stable and reliable meshing transmission effect.

[0069] In some embodiments, the load lower groove is an arc-shaped groove, the front and rear side surfaces of the lower slider 411 are arc-shaped surfaces that fit the inner wall of the load lower groove, and the sliding clamping seat 3 is arranged inside the area surrounded by the arc-shaped groove of the load lower groove. By setting the load lower groove as an arc-shaped groove to provide guidance for the movement of the lower slider 411, the relative position between the load component 43 and the worm wheel 5 on the worm wheel slider 32 can have a larger adjustment range. At the same time, when the worm wheel slider 32 sets the worm wheel 5 at a position closer to the output end of the drive mechanism 2, the middle curved part of the arc-shaped groove can provide a clearance to avoid interference with the output end of the drive mechanism 2, thereby ensuring the normal operation of the detection work.

[0070] In some embodiments, a second connecting hole 412 is provided on the side wall of the load sliding groove corresponding to the lower sliding block 411, and a second locking hole is provided on the lower sliding block 411 corresponding to the second connecting hole 412. The locking screw is passed through the second connecting hole 412 and the second locking hole in sequence and locked to fix the lower sliding block 411 on the load sliding groove.

[0071] In some optional embodiments, the second connection hole 412 on the load slide groove is a bar hole, and the bar holes are distributed along the direction of the load slide groove. The locking screw passes through the bar hole serving as the second connection hole 412 and is screwed into the second locking hole of the lower slider 411. As the lower slider 411 moves in the load slide groove, the locking screw moves synchronously in the bar hole. After the lower slider 411 moves into position, the locking screw is tightened so that the end of the locking screw is pressed against the outer wall of the load slide groove, and the lower slider 411 is pulled toward the load slide groove. The side wall of the load slide groove is locked by the end of the locking screw and the lower slider 411, thereby fixing the relative position between the load slide groove and the lower slider 411, thereby ensuring the stability of the connection and fixed state between the lower slider 411 and the load slide groove, reducing the tightening operation of the locking screw, and improving operational efficiency.

[0072] In some embodiments, a third connecting hole 422 is provided on the side wall of the load upper slide groove 42 corresponding to the upper slider 421, and a third locking hole is provided on the upper slider 421 corresponding to the third connecting hole 422. The locking screw is passed through the third connecting hole 422 and the third locking hole in sequence and locked to fix the upper slider 421 on the load upper slide groove 42.

[0073] In some optional embodiments, the third connection holes 422 on the load upper chute 42 are strip holes distributed along the length of the load upper chute 42. A locking screw passes through the strip holes serving as the third connection holes 422 and screws into the third locking holes of the upper slider 421. As the upper slider 421 moves within the load upper chute 42, the locking screw moves synchronously within the strip holes. Once the upper slider 421 is in position, the locking screw is tightened so that the end of the locking screw presses against the outer wall of the load upper chute 42. The upper slider 421 is then pulled toward the load upper chute 42. This locks the side wall of the load upper chute 42 via the end of the locking screw and the upper slider 421, thereby securing the relative position between the load upper chute 42 and the upper slider 421. This ensures the stability of the connection between the upper slider 421 and the load upper chute 42, reduces the need to tighten the locking screw, and improves operational efficiency.

[0074] In some embodiments, the load assembly 43 includes a reel 431, a wire rope 432, a pulley 433, and a weight 434, wherein:

[0075] The winding wheel 431 is rotatably mounted on the upper slider 421 and has a winding worm wheel 4311 on the top thereof that meshes with the worm wheel 5;

[0076] A wire rope 432 has one end wound around the reel 431 and the other end passed over the pulley 433 and connected to the weight 434;

[0077] The pulley 433 is rotatably mounted on the pulley fixing bases 4331 on both sides of the pedestal 1 .

[0078] When the drive mechanism 2 drives the worm gear 5 to rotate, and the worm gear 5 drives the winding worm gear 4311 on the winding wheel 431 to rotate, the winding wheel 431, which is an integral structure with the winding worm gear 4311, rotates synchronously, thereby achieving the winding and release of the wire rope 432. Under the action of gravity, the weight 434 will hang down from the edge of the base 1 and tighten the wire rope 432. When the winding wheel 431 rotates and reels the wire rope 432, the weight 434 will move upward under the traction of the wire rope 432; when the winding wheel 431 rotates and releases the wire rope 432, the weight 434 will move downward under the action of gravity. The position of the weight 434 is measured by the detection component 44 and transmitted back to the main control system. The rotation angle of the winding wheel 431 can be determined by the displacement of the weight 434. Since the parameters of the winding wheel 431 are fixed and the driving state of the driving mechanism 2 can be set and controlled by the main control system, the displacement of the weight 434 can be measured to obtain the performance parameters of the worm gear 5 to meet the detection requirements.

[0079] In some embodiments, the detection component 44 uses a laser sensor, and the transmitting end of the laser sensor is directed toward the weight 434. When the laser sensor is working, it will emit a laser pulse in the direction of the transmitting end, but when the laser pulse contacts the weight 434 being measured, the laser will be reflected back to the laser sensor. When the laser sensor receives the reflected laser pulse, it measures the time interval from the emission to the return to calculate the distance between the laser sensor and the weight 434. By dynamically obtaining the position state of the weight 434 at different time points and calculating the corresponding distance change through multiple distance values, the displacement of the weight 434 can be obtained, and the corresponding displacement speed of the worm gear 5 being measured can be obtained through the displacement, so as to judge the corresponding performance parameters and meet the inspection requirements of the motor reducer system.

[0080] See also Figure 4 In some embodiments, the driving mechanism 2 includes: a motor base 21, a motor slide 22, and a driving motor 23, wherein:

[0081] The motor base 21 is arranged beside the sliding clamping base 3;

[0082] The motor slide 22 is arranged at the center of the motor base 21;

[0083] The driving motor 23 is arranged on the motor slide 22 , and a worm 231 is provided on the output end. The worm 231 is meshed with the worm wheel 5 for transmission.

[0084] When testing worm wheels 5 with different reduction ratios, the worm 231 on the drive motor 23 also needs to be replaced accordingly. Therefore, in the embodiment provided in the present application, a motor slide 22 is provided at the center of the motor base 21 to movably set the drive motor 23. It is convenient to remove the drive motor 23 from the motor base 21 through the motor slide 22, and then replace the worm 231 on the output end of the drive motor 23 to adapt to the detection drive requirements of different worm wheels 5. In some optional embodiments, the motor slide 22 includes two groups of pressing blocks arranged on the motor base 21. The two groups of pressing blocks are L-shaped structures, and the L-shaped structure is provided with adjustment strip holes on the contact surface with the motor base 21. The adjustment strip holes are distributed in a direction perpendicular to the output end of the drive motor 23. The motor slide 22 is installed and fixed by passing the adjustment strip holes through the locking screw and locking it on the motor base 21. When the motor needs to be locked, first loosen the locking screws so that the motor slide 22 can move within a certain range along the adjustment bar hole, then place the drive motor 23 on the motor slide 22, adjust the output end of the drive motor 23, so that the worm 231 on the output end of the drive motor 23 is located at a position where it can effectively mesh with the worm gear 5 to be tested. Then push the motor slides 22 on both sides toward the drive motor 23, so that the motor slides 22 are pressed against the two side surfaces of the drive motor 23 and locked and fixed by the locking screws, thereby clamping the drive motor 23 and realizing the installation of the drive motor 23. In this way, the worm gear 5 is driven to rotate by the output of the drive motor 23, meeting the detection requirements of the motor reduction box system.

[0085] In some optional embodiments, the driving mechanism 2 also includes a pressure plate 24, which covers the top of the motor slide and is locked and fixed to the motor base 21 by bolts, thereby providing a limited fixation for the top of the driving motor 23 arranged in the motor slide 22 to meet the positioning and clamping requirements of the motor.

[0086] In some embodiments, the pressure plate 24 adopts a flat plate structure. In this case, the bolts used to lock the pressure plate 24 are long bolts. This facilitates that when the pressure plate 24 is covered on the motor slide 22, that is, the pressure plate 24 is suspended above the motor base 21, the pressure plate 24 and the motor base 21 can be locked and fixed by the long bolts. In some embodiments, the pressure plate 24 adopts an "X"-shaped structure. The flat plate end of the top of the pressure plate 24 is covered on the motor slide 22. At the same time, bolts are inserted through the connection holes on the flat plate ends on both sides that are in contact with the motor base 21 to fix the pressure plate 24 on the motor base 21. The driving motor 23 is pressed and fixed by the pressure plate 24 with the "X"-shaped structure, avoiding the bending deformation caused by the force on the two ends of the pressure plate 24, and thus preventing the pressure plate 24 from being deformed or damaged under long-term operation, thereby improving the stability and service life of the overall structure.
