Description

Technical Field

[0001] This invention relates to the field of motor testing technology, and specifically to a motor braking performance testing device. Background Technology

[0002] After the motor is manufactured, its torque and braking performance need to be tested.

[0003] For example, Chinese patent CN217689312U discloses a motor torque detection device, comprising a detection base, a torque sensor connected to the detection base, a fixing frame, and a magnetic powder brake. The torque sensor is located in the middle of the detection base, and the magnetic powder brake is fixed to the rear side of the detection base. The rear end of the rotating shaft of the torque sensor is connected to the output end of the magnetic powder brake. The front side of the detection base has multiple fixing holes spaced along the length of the detection base. The fixing frame has through holes, and the fixing frame and the detection base are fixed together by bolts. The fixing frame is used to fix the motor under test. The motor torque detection device adjusts the distance between the motor under test and the torque sensor by changing the position of the fixing frame, ensuring a stable connection between them. The motor under test can be firmly fixed to the fixing frame. The motor torque detection device can detect motors of various lengths and sizes, preventing vibration of the motor under test due to connection problems during testing and improving detection accuracy.

[0004] While the above structure can be used for testing motors, it cannot automate the testing process and is not suitable for use in continuous production lines.

The voltage-conducting connection assembly 8 moves downward, conducting electricity to motor 6 and simultaneously crimping motor 6 onto the movable support assembly 7. The voltage-conducting connection assembly 8 facilitates power supply to motor 6. The cooperation between the voltage-conducting connection assembly 8 and the movable support assembly 7 facilitates positioning of motor 6, preventing movement of motor 6 during detection and ensuring detection stability. The synchronous clamping assembly of the output positioning clamping assembly 5 moves outward to open, and the lateral movement assembly drives the adaptive rotation assembly to move towards motor 6.

[0061] The thrust of spring 514 is always greater than the centrifugal force of key block 515.

[0062] Specific operations:

[0063] Step 1: Connect the mounting hole of motor 6 to the positioning post 71, and crimp the wires of motor 6 into the wire clamp 73;

[0064] Step 2: The double-speed chain conveyor drives the moving plate 72 to move between the base plate 1 and the conductive voltage connection component 8. The double-speed chain conveyor locks and positions the moving plate 72. The third cylinder 83 drives the pressure plate 81 to move along the third guide rail assembly 84. The pressure plate 81 moves to contact the top of the motor 6 and presses the motor 6 onto the moving plate 72, which facilitates the upward movement of the motor 6 along the positioning column 71 during subsequent testing. At the same time, the conductive column 82 contacts the wires of the motor 6 to energize the wires of the motor 6. The conductive voltage connection component 8 facilitates the supply of power to the motor 6. The conductive voltage connection component 8 and the moving support component 7 work together to facilitate the positioning of the motor 6 and prevent the motor 6 from moving during testing, thus ensuring the stability of the testing.

[0065] Step 3: The second cylinder 55 of the lateral movement assembly drives the support frame 56 to move along the first guide rail assembly 54. The support frame 56 drives the rotating disk 57 of the adaptive rotation assembly to move towards the motor 6. The rotating disk 57 of the adaptive rotation assembly drives the arc-shaped clamping plate 516 of the synchronous clamping assembly to move to the outside of the drive shaft of the motor 6. The first cylinder 52 of the synchronous clamping assembly drives the first mounting frame 53 to move towards the motor 6. The first mounting frame 53 drives the fixing ring 58 to move. The fixing ring 58 drives the horizontal sliding plate 512 to move. The horizontal sliding plate 512 drives the first wedge block 513 to move towards the motor 6. The first wedge block 513 moves along the guide rail. 520 drives the second wedge block 518 to move inward along the guide rail of the second guide rail assembly 519. The second wedge block 518 drives the arc-shaped clamping plate 516 to move inward. The arc-shaped clamping plate 516 moves to the outside of the drive shaft of the motor 6. The key block 515 contacts the drive shaft of the motor 6. The drive shaft of the motor 6 presses the key block 515 into the second slide groove 521. The conductive voltage connection assembly 8 controls the rotation of the motor 6. The rotation of the drive shaft of the motor 6 drives the keyway of the drive shaft to rotate to the key block 515 of the keyway positioning assembly. The restoring force of the spring 514 pushes the key block 515 into the keyway of the drive shaft of the motor 6, clamping and fixing the drive shaft of the motor 6.

[0066] Step 4: The conductive voltage connection component 8 controls the rotation of the motor 6. The keyway of the drive shaft of the motor 6 drives a set of key blocks 515 of the adaptive rotation component to rotate. The set of key blocks 515 drives a set of arc-shaped clamps 516 to rotate. The set of arc-shaped clamps 516 drives a set of second wedge blocks 518 to rotate. The set of second wedge blocks 518 drives a set of first wedge blocks 513 to rotate via the guide rail 520. The rotation of the set of first wedge blocks 513 drives a set of horizontal slide plates 512 to rotate. The set of horizontal slide plates 512 drives the rotating disk 57 to rotate. The rotating disk 57 drives the connecting shaft 511 to rotate. The connecting shaft 511 drives the second circular plate 522 to rotate. The second circular plate 522 drives the slide rod 51 to rotate. The slide rod 51 drives the first circular plate 510 to rotate. The first circular plate 510 drives the horizontal shaft 3 to rotate. During braking detection, the magnetic powder brake 2 provides braking force, and the torque sensor 4 detects the torque, realizing the automated braking performance detection of the motor 6.

[0067] Step 5: After the current motor 6 is detected, the first cylinder 52 of the synchronous clamping assembly drives the first mounting bracket 53 to move away from the motor 6. The first mounting bracket 53 drives the fixing ring 58 to move. The fixing ring 58 drives the horizontal sliding plate 512 to move. The horizontal sliding plate 512 drives the first wedge block 513 to move away from the motor 6. The first wedge block 513 drives the second wedge block 518 to move outward along the guide rail of the second guide rail assembly 519 through the guide rail 520. The second wedge block 518 drives the arc-shaped clamping plate 516 to move outward. The arc-shaped clamping plate 516 drives the keyway of the motor 6 drive shaft to separate.

[0068] Step 6: The second cylinder 55 of the transverse component drives the support frame 56 to move along the first guide rail assembly 54. The support frame 56 drives the rotating disk 57 of the adaptive rotation component to move away from the motor 6. The rotating disk 57 of the adaptive rotation component drives the arc-shaped clamping plate 516 of the synchronous clamping component to move to the outer side of the end of the drive shaft of the motor 6 near the magnetic powder brake 2. The output end positioning clamping component 5 does not affect the movement of the double speed chain conveyor drive motor 6.

[0069] Step 7: The third cylinder 83 drives the pressure plate 81 to move along the third guide rail assembly 84, the pressure plate 81 separates from the motor 6, and the conductive post 82 separates from the wire of the motor 6.

[0070] Step 8: Repeat steps 2-7.
