Description
Technical Field
[0001] This utility model relates to the field of motor testing technology, specifically to an online testing device for the traction force of a synchronous reduction gear motor. Background Technology
[0002] Gear reducer motors, also known as geared motors or geared motors, are motor-driven closed-loop gear reduction devices. They are integrated motors and gearboxes used to reduce speed and increase torque to meet the needs of mechanical equipment. Gear motors are characterized by their small size, high torque, and low noise, making them a vital component of automation and a preferred choice for transmission machinery companies.
[0003] Currently, existing online testing devices for motor traction force have the following problems: the motor needs to be installed before testing, which involves many installation steps and results in low testing efficiency.
[0004] Patent CN 214951913 U discloses an online testing device for the traction force of a synchronous reduction gear motor. The device includes a workbench with a traction mechanism and a placement plate on its top. The traction mechanism comprises a take-up reel and a test box, both horizontally positioned with the take-up reel directly in front of the placement plate. Supports are mounted on both sides of the take-up reel and connected to the workbench via these supports. A connecting sleeve is installed at the shaft end of the take-up reel, near the placement plate, and is located on the centerline of the placement plate. A pull rope is wound around the take-up reel, with its end extending into the test box and connected to a pull plate. This invention uses manual or automatic methods to drive the clamping plate to hold the motor, inserting the motor's wires into the socket for conductivity, and pushing the placement plate to connect the motor's output end to the connecting sleeve to test the motor's traction force. The device is easy to operate and has high testing efficiency.
[0005] However, after the device finishes testing the motor, the motor needs to be removed and replaced before testing can be performed again. The testing interval is relatively long, and the efficiency is generally low. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] To address the shortcomings of existing technologies, this invention provides an online testing device for the traction force of a synchronous reduction gear motor, thus solving the aforementioned technical problems.
[0008] (II) Technical Solution
[0009] To achieve the above objectives, this utility model provides the following technical solution: an online testing device for the traction force of a synchronous reduction gear motor, comprising a device body and a motor to be tested. A servo motor is mounted on the device body, and a rotating disk is mounted on the output shaft of the servo motor. Four limiting grooves are formed on the rotating disk, and limiting sliders are slidably arranged within the limiting grooves. A movable clamp is mounted on the top of the limiting slider, and the motor to be tested is clamped on the movable clamp. A mounting frame is provided on the device body, and an electric telescopic rod is mounted at the end of the mounting frame. Two support frames protrude from the device body, and a rotating cylinder is rotatably mounted on each support frame. A torque detector is mounted on one of the support frames, with its detection end mounted on the rotating cylinder. A connecting end is mounted on the other support frame, penetrating the support frame and mounted on the rotating cylinder. Four support columns protrude from the bottom of the device body.
[0010] Preferably, the surface of the rotating drum is provided with multiple scale grooves along the circumferential direction, and a pointer is protruding on the support frame near the scale grooves.
[0011] Preferably, the movable clamp has two symmetrical sliding rods slidably mounted on it, and an arc-shaped gripper is mounted on one end of the two sliding rods that are close to each other.
[0012] Preferably, a return spring is sleeved on the slide rod, with one end of the return spring abutting against the movable clamp and the other end of the return spring abutting against the arc-shaped gripper.
[0013] Preferably, a guide rod is provided in the limiting groove, and the limiting slider is slidably arranged on the guide rod.
[0014] Preferably, a compression spring is sleeved on the guide rod, with one end of the compression spring abutting against the inner wall of the limiting groove and the other end of the compression spring abutting against the limiting slider.
[0015] Preferably, the end of the slide bar away from the arc-shaped gripper is provided with a handle, and the outer surface of the handle is covered with an anti-slip rubber sleeve.
[0016] Compared with the prior art, this utility model provides an online testing device for the traction force of a synchronous reduction gear motor, which has the following advantages: This utility model, through the cooperation of a rotating disk, movable clamps, and connecting ends, allows multiple motors to be tested to be sequentially fixed on four movable clamps. A servo motor can then be started to rotate the rotating disk, causing the movable clamps to move sequentially to the front of the support frame and align with the connecting ends on the same axis. At this point, an electric telescopic rod can be activated to push the movable clamps along the limiting groove, allowing the output shaft of the motor to be tested, fixed on the movable clamp, to align with the connecting end. This allows the motor to be started, and the traction force of the motor can be tested via a rotating drum and a torque detector. After testing, the movable clamps are reset, and the servo motor is started to move the next movable clamp to the testing position, greatly shortening the interval between two tests and thus improving work efficiency.

[0025] Please see Figure 1-4 A synchronous reduction gear motor traction force online testing device includes a main body 1 and a motor 5 to be tested. A servo motor 18 is mounted on the main body 1. A rotating disk 3 is mounted on the output shaft of the servo motor 18. Four limiting grooves 9 are opened on the rotating disk 3. Limiting sliders 19 are slidably arranged in the limiting grooves 9. A movable clamp 4 is mounted on the top of the limiting slider 19. The motor 5 to be tested is clamped on the movable clamp 4. A mounting frame 7 is mounted on the main body 1. An electric telescopic rod 8 is mounted at the end of the mounting frame 7. Two support frames 10 protrude from the main body 1. A rotating cylinder 12 is rotatably mounted on the support frame 10. A torque detector 15 is mounted on one support frame 10. The detection end of the torque detector 15 is mounted on the rotating cylinder 12. A connecting end 11 is mounted on the other support frame 10. The connecting end 11 passes through the support frame 10 and is mounted on the rotating cylinder 12. Four support columns 2 protrude from the bottom of the main body 1.
[0026] By cooperating with the rotating disk 3, movable clamps 4, and connecting end 11, multiple motors 5 to be tested can be sequentially fixed on four movable clamps 4. The rotating disk 3 can be rotated by starting the servo motor 18, causing the movable clamps 4 to move sequentially to the front of the support frame 10 and be on the same axis as the connecting end 11. At this time, the movable clamps 4 can be pushed along the limit slide groove 9 by starting the electric telescopic rod 8, so that the output shaft of the motor 5 to be tested fixed on the movable clamp 4 is connected to the connecting end 11. The motor 5 to be tested can then be started, and the traction force of the motor can be detected by the rotating drum 12 and the torque detector 15. After the test is completed, the movable clamps 4 are reset, and the servo motor 18 is started to move the next movable clamp 4 to the test position, which greatly shortens the interval between two tests and improves work efficiency.
[0027] Specifically, in this embodiment, the surface of the rotating drum 12 is provided with a plurality of scale grooves 13 along the circumferential direction, and the support frame 10 near the scale grooves 13 is provided with a pointer 14.
[0028] Through the cooperation of the scale groove 13 and pointer 14, the rotating drum 12 can be driven to rotate by the motor 5 under test, thereby changing the scale on the rotating drum 12, so that the operator can directly observe the test value.
[0029] Specifically, in this embodiment, two symmetrical sliding rods 17 are slidably mounted on the movable clamp 4. An arc-shaped gripper 6 is installed at one end of the two sliding rods 17 that is close to each other. A return spring 16 is sleeved on the sliding rod 17. One end of the return spring 16 abuts against the movable clamp, and the other end of the return spring 16 abuts against the arc-shaped gripper 6.
[0030] With the provided slide bar 17 and return spring 16, the arc-shaped gripper 6 can always press against the motor 5 under test by the elastic force of the spring, thereby clamping and fixing the motor 5 under test by the two arc-shaped grippers 6.
[0031] Specifically, in this embodiment, a guide rod 20 is provided in the limiting slide groove 9, and the limiting slider 19 is slidably arranged on the guide rod 20. A compression spring 21 is sleeved on the guide rod 20. One end of the compression spring 21 abuts against the inner wall of the limiting slide groove 9, and the other end of the compression spring 21 abuts against the limiting slider 19.
[0032] By setting the guide rod 20, the movement direction of the limiting slider 19 and the movable clamp 4 can be restricted. By setting the compression spring 21, the compression spring 21 can be squeezed when the electric telescopic rod 8 pushes the movable clamp 4 to move in the direction of the rotating drum 12. When the action output end of the electric telescopic rod 8 retracts, the compression spring 21 drives the movable clamp 4 to automatically reset.
[0033] Specifically, in this embodiment, a handle is provided at the end of the slide bar 17 away from the arc-shaped gripper 6, and the outer surface of the handle is covered with an anti-slip rubber sleeve.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
