Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, specifically a micro motor testing device with adjustable multiple degrees of freedom. Background Technology

[0002] Miniature motors are electric motors that are small in size, have low power, and have a precise structure. They are widely used in consumer electronics, medical devices, industrial automation, robotics, and automotive electronics.

[0003] In the production process of micro motors, in order to ensure the quality control of micro motors, various tests are generally required. Among them, the hysteresis dynamometer is one of the most common devices for testing micro motors. It can perform torque characteristic tests, speed and power tests, efficiency and temperature rise tests, etc. The basic principle of the hysteresis dynamometer is based on the hysteresis effect and eddy current effect. It converts mechanical energy into heat energy through non-contact electromagnetic action, so as to achieve accurate measurement of the motor output torque and power.

[0004] Hysteresis dynamometers are typically used in a horizontal configuration, with the motor placed horizontally on a workbench for testing. However, due to their application scenarios, micro motors are not typically used horizontally. This discrepancy between the testing conditions and the actual usage environment leads to inaccurate measurements. Therefore, we propose a micro motor testing device with adjustable degrees of freedom. Utility Model Content

[0005] The purpose of this invention is to provide a micro motor testing device that can be adjusted with multiple degrees of freedom, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a base, a support column fixedly connected to the top of the base, a mounting plate rotatably connected to the top of the support column, a mounting plate fixedly connected to the top of the mounting plate, and fixing plates fixedly connected to both sides of the top of the base. A limiting groove is formed on the side of the fixing plate closest to the support column, the limiting groove being aligned with the horizontal position of the support column. Several horizontal adjustment grooves aligned with the horizontal height of the limiting groove are formed on the side of the fixing plate closest to the support column, and several vertical adjustment grooves aligned with the vertical direction of the limiting groove are formed on the side of the fixing plate closest to the support column.

[0007] A limiting head is slidably connected in the limiting groove. A mounting base is fixedly connected to one end of the limiting head near the support column. An installation groove is opened on the top of the mounting base. A limiting rod is fixedly connected in the installation groove. A traction rope is placed in the installation groove. The traction rope is located below the limiting rod. The two ends of the traction rope are fixedly connected to the bottom sides of the mounting plate, respectively.

[0008] Preferably, a hysteresis dynamometer is fixedly connected to the top center of the mounting plate, and an air cooler is fixedly connected to one side of the top of the mounting plate. The hysteresis dynamometer and the air cooler are connected by a coupling.

[0009] Preferably, a mounting bracket is fixedly connected to the top of the mounting plate on the side away from the air cooler, and a micro motor body is provided on the top of the mounting bracket. The output shaft of the micro motor body is connected to the hysteresis dynamometer via a coupling.

[0010] Preferably, each of the horizontal adjustment slots is located on one side of the limiting slot, and each of the vertical adjustment slots is located above the limiting slot, and the spacing between the horizontal adjustment slots is greater than the spacing between the vertical adjustment slots.

[0011] Preferably, springs are fixedly connected to both ends of the top of the fixing plate, and a baffle is fixedly connected between the tops of the two springs.

[0012] Preferably, the mounting bracket has limit openings on both sides of the top, and the micro motor body is fitted with several fixing strips, the two ends of which are fixed to the limit openings by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When testing a micro motor, this invention uses two mounting bases with limiting heads placed in the horizontal and vertical adjustment slots of a fixed plate on the same side. The mounting plate tilts towards the limiting head in the horizontal adjustment slot. The mounting base on the limiting head side in the vertical adjustment slot, along with a traction rope, limits the tilt of the mounting plate, maintaining its current tilt. This allows the micro motor to be tested in a way that matches its placement in the actual working environment, resulting in more accurate test data. This avoids the problem of inaccurate data obtained when traditional testing devices are used for micro motors and the placement differs from the actual usage scenario. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a micro motor testing device with multi-degree-of-freedom adjustment, including a base 1, a support column 11 fixedly connected to the top of the base 1, a mounting plate 12 rotatably connected to the top of the support column 11, a mounting plate 2 fixedly connected to the top of the mounting plate 12, a hysteresis dynamometer 21 fixedly connected to the middle of the top of the mounting plate 2, an air cooler 22 fixedly connected to one side of the top of the mounting plate 2, the hysteresis dynamometer 21 and the air cooler 22 being connected by a coupling, a mounting frame 3 fixedly connected to the side of the top of the mounting plate 2 away from the air cooler 22, a micro motor body 31 being provided on the top of the mounting frame 3, the output shaft of the micro motor body 31 being connected to the hysteresis dynamometer 21 by a coupling, limit ports 32 being provided on both sides of the top of the mounting frame 3, and several fixing strips 33 being fitted on the micro motor body 31, the two ends of the fixing strips 33 being fixed to the limit ports 32 by bolts.

[0023] Next, the micro motor body 31 is placed on the mounting bracket 3, and then the fixing strip 33 is clipped onto the outside of the micro motor body 31. Then, the fixing strip 33 is fixed to the limiting port 32 with bolts. At this time, the micro motor body 31 can be fixed and limited by the fixing strip 33. Then, the output end of the micro motor body 31 is connected to the hysteresis dynamometer 21 through a coupling. Then, the micro motor body 31 is started to run. During operation, the micro motor body 31 can input mechanical energy into the hysteresis dynamometer 21. At this time, the hysteresis dynamometer 21 will receive the power of the micro motor, drive the rotor to rotate in the magnetic field, generate hysteresis braking torque, and transmit the test data to the external working computer for the staff to view. At the same time, when the hysteresis dynamometer 21 receives the power of the micro motor, it will drive the fan blades in the air cooler 22 to rotate, and complete the heat dissipation work.

[0024] Combined with appendix Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, fixing plates 4 are fixedly connected to both sides of the top of the base 1. A limiting groove 41 is formed on the side of the fixing plate 4 near the support column 11, and the limiting groove 41 is aligned horizontally with the support column 11. Several horizontal adjustment grooves 42, aligned horizontally with the limiting grooves 41, are formed on the side of the fixing plate 4 near the support column 11. Several vertical adjustment grooves 43, aligned vertically with the limiting grooves 41, are formed on the side of the fixing plate 4 near the support column 11. Each horizontal adjustment groove 42 is located on one side of the limiting groove 41, and each vertical adjustment groove 43 is located above the limiting groove 41. The spacing between the two springs is greater than the spacing between the vertical adjustment grooves 43. The top two ends of the fixed plate 4 are fixedly connected to springs 44. The top of the two springs 44 is fixedly connected to baffles 45. The limiting head 51 is slidably connected in the limiting groove 41. The end of the limiting head 51 near the support column 11 is fixedly connected to the mounting base 5. The top of the mounting base 5 is provided with a mounting groove 52. The limiting rod 53 is fixedly connected in the mounting groove 52. The traction rope 54 is placed in the mounting groove 52. The traction rope 54 is located below the limiting rod 53. The two ends of the traction rope 54 are fixedly connected to the bottom sides of the mounting plate 2 respectively.

[0025] Furthermore, when a tilt test is required on the micro motor body 31, first determine the tilt direction of the micro motor body 31. Then, holding the mounting base 5, pull the limiting rod 53 out of the limiting groove 41 on the same side. Next, move the limiting rod 53 at the position corresponding to the tilt direction of the micro motor body 31 into the horizontal adjustment groove 42, and move the limiting rod 53 on the other side into the vertical adjustment groove 43 of the fixing plate 4 on the same side. According to the required tilt angle of the micro motor body 31, place the limiting rod 53 in different horizontal adjustment grooves 4. 2. Within the vertical adjustment groove 43, the further the limiting rod 53 is inserted into the horizontal adjustment groove 42 from the limiting groove 41, the greater the tilt angle of the mounting plate 2. When the limiting rod 53 on the other side is inserted into the vertical adjustment groove 43, its position must correspond to the position of the limiting rod 53 inserted into the horizontal adjustment groove 42. For example, when the limiting rod 53 corresponding to the tilt direction of the micro motor body 31 is inserted into the horizontal adjustment groove 42 adjacent to the limiting groove 41, the limiting head 51 on the other side should be inserted into the vertical adjustment groove adjacent to the upper limit groove 41 of the same side fixing plate 4. Within 43, when the limiting head 51 moves from the limiting groove 41 into the horizontal adjustment groove 42, due to the limited length of the traction rope 54, the limiting head 51 can only be inserted into the horizontal adjustment groove 42 by tilting the mounting plate 2. At the same time, the limiting head 51 on the other side is inserted into the vertical adjustment groove 43, and together with the traction rope 54 on the same side, continues to pull and limit the raised side of the mounting plate 2. Through the cooperation of the two traction ropes 54 and the mounting base 5, the tilted mounting plate 2 is limited, maintaining its current tilt angle. The micro motor body 31 can then be tested. During the tilting process of the mounting plate 2, before the limiting head 51 is inserted into the horizontal adjustment slot 42 and the vertical adjustment slot 43, the mounting plate 2 is not limited at this time. Therefore, it will tilt on its own according to the difference in weight on both sides until it rests on the baffle 45. At this time, the impact force generated when the mounting plate 2 rests on the baffle 45 is reduced by the buffering function of the spring 44, thereby protecting the micro motor body 31, hysteresis dynamometer 21 and air cooler 22 on the mounting plate 2.

[0026] Working principle: Place the device in the designated working position, then place the micro motor body 31 on the mounting bracket 3, then clip the fixing strip 33 onto the outside of the micro motor body 31, and then use bolts to fix the fixing strip 33 to the limit port 32. At this time, the micro motor body 31 can be fixed and limited by the fixing strip 33. Then, the output end of the micro motor body 31 is connected to the hysteresis dynamometer 21 through the coupling.

[0027] Then, the micro motor body 31 is started to run. During operation, the micro motor body 31 can input mechanical energy into the hysteresis dynamometer 21. At this time, the hysteresis dynamometer 21 will receive the power of the micro motor, drive the rotor to rotate in the magnetic field, generate hysteresis braking torque, and transmit the test data to the external working computer for the staff to view. At the same time, when the hysteresis dynamometer 21 receives the power of the micro motor, it will drive the fan blades in the air cooler 22 to rotate and complete the heat dissipation work.

[0028] When a tilt test is required on the micro motor body 31, first determine the tilt direction of the micro motor body 31. Then, holding the mounting base 5, pull the limiting rod 53 out of the limiting groove 41 on the same side. Next, move the limiting rod 53 at the position corresponding to the tilt direction of the micro motor body 31 into the horizontal adjustment groove 42, and move the limiting rod 53 on the other side into the vertical adjustment groove 43 of the fixing plate 4 on the same side. According to the required tilt angle of the micro motor body 31, place the limiting rod 53 in different horizontal adjustment grooves 42 and vertical adjustment grooves 43. The farther the limiting rod 53 is inserted into the horizontal adjustment groove 42 from the limiting groove 41, the greater the tilt angle of the mounting plate 2. The other limiting rod 53 is placed in the horizontal adjustment groove 42 further away from the limiting groove 41. When inserted into the vertical adjustment slot 43, it needs to correspond to the position of the limiting rod 53 inserted into the horizontal adjustment slot 42. When the limiting head 51 moves from the limiting slot 41 into the horizontal adjustment slot 42, due to the limited length of the traction rope 54, the limiting head 51 can only be inserted into the horizontal adjustment slot 42 by tilting the mounting plate 2. At this time, the limiting head 51 on the other side is inserted into the vertical adjustment slot 43, and together with the traction rope 54 on the same side, it continues to pull and limit the side of the mounting plate 2 after it is raised. Through the cooperation of the two traction ropes 54 and the mounting base 5, the tilted mounting plate 2 is limited to maintain the current tilt angle. Then, the tilted test work of the micro motor body 31 can continue.
