[0002] Planetary gear motors (electric motors) are widely used in various electrical appliances. After the planetary gear motors are manufactured, it is necessary to test their output torques, including no-load tests and load tests. For the load tests of the motors, torque testers need to be used. However, during the torque testing process, after placing the workpiece to be tested, the workpiece needs to be clamped and fixed, and then the test switch is turned on to start the test, and its detection efficiency is relatively low. Therefore, it is necessary to manufacture a planetary gear motor load torque testing device to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a planetary gear motor load torque testing device to solve the problems mentioned in the background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

The baffle is vertically fixed at the rear end of the base, and a limiting groove is provided at the upper end of the baffle, and the limiting groove is U-shaped.

[0007] Further description of the present utility model: The elastic telescopic member includes a push rod and a compression spring. An installation blind hole is provided in the base along the front-back direction. The rear end of the push rod is slidably connected to the installation blind hole. The front end of the push rod is fixed on the insulating push block. The compression spring is placed in the installation blind hole and its front end contacts the rear end of the push rod. Two sets of the push rod and the compression spring are provided on the insulating push block respectively.

[0008] Further description of the present utility model: The limiting member includes a second connecting frame and an elastic buffer block.

Information such as the test time and torque is displayed on the display screen of the total control box. After the detection is completed, the operator releases the insulating push block. Under the action of the return spring and the elastic telescopic member, the carrier component resets. The operator can then take out the tested product and put in the product to be tested, and operate repeatedly like this. The advantage of this design is that after placing the product to be tested, only by pushing the insulating push block can the load torque detection be completed, without the need for cumbersome operations such as product clamping and starting the switch, effectively improving the detection efficiency.

[0017] The present utility model will be further described below with reference to the accompanying drawings:

[0018] As Figures 1 to 4As shown in the figure, a planetary gear motor load torque testing device includes a first mounting bracket 1, a second mounting bracket 2, a mounting platform 3, a carrier assembly 4, a detector assembly 5, a total control box 6, and a parameter adjustment assembly 7. The mounting platform 3 is horizontally fixed on the first mounting bracket 1. The second mounting bracket 2 is erected above the mounting platform 3. The carrier assembly 4, the detector assembly 5, and the parameter adjustment assembly 7 are all fixed on the mounting platform 3. The total control box 6 is fixed above the second mounting bracket 2. The carrier assembly 4 includes a slide 41, a slider 42, a first connecting frame 43, a return spring 44, a carrier body 45, an elastic telescopic member 46, an insulating push block 47, a metal connecting column 48, and a limiting member 49. The slide 41 is fixed above the mounting platform 3 in the front-rear direction and corresponds to the front side of the detector assembly 5. The lower end of the slider 42 is slidably connected to the slide 41. The first connecting frame 43 is fixed on the mounting platform 3 and corresponds to the front side of the slide 41. The front and rear ends of the return spring 44 are respectively fixed on the slider 42 and the first connecting frame 43. The carrier body 45 is fixed above the slider 42. The elastic telescopic end of the elastic telescopic member 46 is mounted on the carrier body 45. The front end of the elastic telescopic member 46 is fixed on the insulating push block 47. The metal connecting column 48 is fixed on the insulating push block 47 and corresponds to the front side of the carrier body 45. There are two sets of metal connecting columns 48, which are respectively electrically connected to the total control box 6 through wires. The limiting member 49 is fixed on the mounting platform 3 and corresponds to the rear side of the slider 42. Both the detector assembly 5 and the parameter adjustment assembly 7 are electrically connected to the total control box 6.

[0019] Before the test, the operator pre-sets parameters such as load current, load voltage, and test time on the parameter adjustment assembly 7. Then, the motor to be tested is placed on the carrier assembly 4. The output shaft of the motor faces the rear end, and the positive and negative poles of the motor are arranged at the front end. At this time, the positive and negative poles are not in contact with the metal connecting column 48. Manually push the insulating push block 47 backward, and the return spring 44 is stretched. Until the carrier body 45 contacts the limiting member 49, the carrier body 45 stops moving. At this time, the output end of the motor is connected to the detection end of the detector assembly 5. The insulating push block 47 continues to move backward, and the elastic telescopic member 46 is gradually compressed. When the two sets of metal connecting columns 48 respectively contact the positive and negative poles of the motor, a circuit is formed with the total control box 6, and the operation of the detector assembly 5 is automatically started to perform torque detection on the output end of the motor according to the preset data. Information such as the test time and torque is displayed on the display screen of the total control box 6. After the detection is completed, the operator releases the insulating push block 47. Under the action of the return spring 44 and the elastic telescopic member 46, the carrier assembly 4 resets. The operator can then take out the tested product and put in the product to be tested, and repeat the operation like this. The advantage of this design is that after placing the product to be tested, only by pushing the insulating push block 47 can the load torque detection be completed, without the need for cumbersome operations such as product clamping and starting the switch, effectively improving the detection efficiency.

[0020] The vehicle body 45 includes a base 451 and a baffle 452. The base 451 is fixed on the slider 42. A placement groove 4511 is formed above the base 451. The placement groove 4511 is V-shaped. The baffle 452 is vertically fixed at the rear end of the base 451. A limiting groove 4521 is provided at the upper end of the baffle 452. The limiting groove 4521 is U-shaped. The motor is placed on the placement groove 4511, and the bearing position of the motor corresponds to the inside of the limiting groove 4521. By setting the placement groove 4511 to be V-shaped, motors with different outer diameter sizes can be placed adaptively.

[0021] The elastic telescopic member 46 includes a push rod 461 and a compression spring 462. An installation blind hole 4512 is provided in the base 451 along the front-rear direction. The rear end of the push rod 461 is slidably connected to the installation blind hole 4512. The front end of the push rod 461 is fixed on the insulating push block 47. The compression spring 462 is placed in the installation blind hole 4512 and its front end contacts the rear end of the push rod 461. Two sets of the push rod 461 and the compression spring 462 are provided on the insulating push block 47 respectively.

[0022] When the rear end of the vehicle body 45 contacts the limiting member 49, as the insulating push block 47 continues to push, the compression spring 462 is compressed, so that the metal connection column 48 approaches the motor, and finally contacts the positive and negative electrodes of the motor.

[0023] The limiting member 49 includes a second connecting frame 491 and an elastic buffer block 492. The second connecting frame 491 is fixed above the installation platform 3. The elastic buffer block 492 is fixed on the front side of the second connecting frame 491 and corresponds to the rear side of the slider 42. The elastic buffer block 492 not only limits the vehicle body 45, but also can play a buffering role.

[0024] The detector assembly 5 includes a first vertical frame 51, a second vertical frame 52, a torque sensor 53, a drive shaft 54, a power output component 55, a first coupling 56 and a second coupling 57. The torque sensor 53 is fixed on the installation platform 3. The first vertical frame 51 and the second vertical frame 52 are both fixed on the installation platform 3 and respectively correspond to the front and rear sides of the torque sensor 53. The drive shaft 54 is rotatably installed on the first vertical frame 51. The power output component 55 is fixed on the second vertical frame 52. The front end of the torque sensor 53 is connected to the drive shaft 54 through the first coupling 56. The rear end of the torque sensor 53 is connected to the power output end of the power output component 55 through the second coupling 57. Both the torque sensor 53 and the power output component 55 are electrically connected to the total control box 6.

[0025] After the output end of the motor is connected to the drive shaft 54 and the motor forms a circuit with the total control box 6, the power supply in the total control box 6 enables the power output component 55 to drive the second coupling 57 to rotate, and then drives the output end of the motor to rotate through the torque sensor 53, the first coupling 56 and the drive shaft 54 in sequence, so as to obtain torque data through the torque sensor 53, and transmit it back to the total control box 6 and display it on the display screen.

[0026] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
