Description

Technical Field

[0001] This utility model relates to the field of motor testing, and in particular to a device for testing the horizontal push-pull force of a stepper motor. Background Technology

[0002] With the increasing application of stepper motors, performance evaluation and quality testing of stepper motors have become key links to ensure their stable and efficient operation. The push-pull performance of stepper motors, as one of the important indicators for measuring their performance, is directly related to the applicability and reliability of the motor in actual working scenarios.

[0003] Existing stepper motor horizontal push-pull force tests typically involve mounting the stepper motor on a testing device and then using that device to measure the motor's push-pull force. However, most current testing devices suffer from limitations such as limited functionality and complex operation. Some devices can only test the motor's push-pull force under specific load conditions and cannot flexibly adjust the number of weights to simulate different load conditions. Consequently, the test results cannot fully reflect the motor's performance under various actual load conditions, affecting testing efficiency and accuracy.

[0004] Therefore, it is necessary to design a stepper motor horizontal push-pull force testing device that can adjust the number of weights to test the push-pull force of the motor under different load conditions, is simple to operate, facilitates comprehensive evaluation of motor performance and maximum load capacity, and improves testing efficiency and accuracy. Utility Model Content

[0005] To overcome the shortcomings of some current testing devices that can only test the push-pull force of motors under specific load conditions and cannot flexibly adjust the number of weights to simulate different load conditions, resulting in test results that cannot fully reflect the performance of motors under various actual load conditions, thus affecting testing efficiency and accuracy, this utility model provides a stepper motor horizontal push-pull force testing device that can adjust the number of weights to test the push-pull force of motors under different load conditions. It is simple to operate, facilitates a comprehensive evaluation of motor performance and maximum load capacity, and improves testing efficiency and accuracy.

[0006] Technical Solution: A horizontal push-pull force testing device for a stepper motor includes a base frame, a mounting base, a motor, a coupling, a lead screw, a guide rod, a sliding seat, a force adjustment mechanism, and a stabilizing mechanism. The mounting base is connected to the upper left side of the base frame, and the motor is connected to the mounting base. The motor and a processor are electrically connected via a control module. The coupling is rotatably connected to the upper part of the mounting base and is connected to the output shaft of the motor. A lead screw is connected to the right side of the coupling and is rotatably connected to the base frame. Guide rods are connected to the upper front and rear sides of the base frame, and a sliding seat is slidably connected between the guide rods. The sliding seat is connected to the lead screw via a thread. The sliding seat is equipped with a force adjustment mechanism for adjusting and testing the push-pull force. Stabilizing mechanisms are provided on both the left and right sides of the base frame for stabilizing the force adjustment mechanism.

[0007] Optionally, the mounting base is L-shaped.

[0008] Optionally, the force adjustment mechanism includes hooks, ropes, hooks, support seats, weights, and fixed pulleys. The front and rear parts of the sliding seat are each connected to two hooks, each hook is suspended from a hook, each hook is connected to a rope, and the end of each rope is connected to a support seat. Multiple stacked weights are placed on each support seat. The front and rear parts of the base frame are each rotatably connected to two fixed pulleys, and each rope passes around an adjacent fixed pulley.

[0009] Optionally, the hook can be made of steel.

[0010] Optionally, the stabilizing mechanism includes a fixed ring, a stabilizing clamping ring, and a spring. Two fixed rings are connected to the left and right sides of the base frame, and stabilizing clamping rings are slidably connected to the front and rear parts of the fixed rings. The stabilizing clamping rings are in contact with the adjacent pull ropes, and springs are connected between the stabilizing clamping rings and the adjacent fixed rings.

[0011] Optionally, the sides of the stabilizing clamping rings that are close to each other are both arc-shaped.

[0012] The beneficial effects of this utility model are: 1. This utility model hooks the left or right hook onto the hook ring, places different numbers of weights on the load-bearing seat, and then uses a motor to move the sliding seat, which in turn moves the load-bearing seat and the weights to measure the push-pull force of the motor. This allows for the adjustment of the number of weights to test the push-pull force of the motor under different load conditions. The operation is simple, facilitates a comprehensive evaluation of the motor's performance and maximum load capacity, and improves testing efficiency and accuracy.

[0013] 2. This utility model fixes the hook and pull rope by passing them through the fixed ring on the left and then around the fixed pulley on the left. The hook is then hooked onto the hook ring for fixation. After releasing the stabilizing clamping ring, the spring rebounds, and the stabilizing clamping ring moves in the opposite direction to reset and contact the pull rope. During testing, the stabilizing clamping ring provides stable guidance, thereby ensuring the pull rope is stably guided during testing, preventing the pull rope from shifting or falling off, and improving the stability of the test.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0021] A device for testing the horizontal push-pull force of a stepper motor, such as Figures 1-5 As shown, the system includes a base frame 1, a mounting base 2, a motor 3, a coupling 4, a lead screw 5, a guide rod 6, a sliding seat 7, a force adjustment mechanism 8, and a stabilizing mechanism 9. The mounting base 2 is connected to the upper left side of the base frame 1. The mounting base 2 is L-shaped for easy support. The motor 3 is connected to the mounting base 2. The motor 3 and the processor are electrically connected via a control module. The coupling 4 is rotatably connected to the upper part of the mounting base 2. The coupling 4 is connected to the output shaft of the motor 3. The lead screw 5 is connected to the right side of the coupling 4. The lead screw 5 is rotatably connected to the base frame 1. The guide rods 6 are connected to the upper front and rear sides of the base frame 1. The sliding seat 7 is slidably connected between the guide rods 6. The sliding seat 7 is connected to the lead screw 5 via a thread. The sliding seat 7 is provided with a force adjustment mechanism 8 for adjusting and testing the push-pull force. The base frame 1 is provided with stabilizing mechanisms 9 on both the left and right sides for stabilizing the force adjustment mechanism 8.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the force adjustment mechanism 8 includes a hook 81, a pull rope 82, a hook 83, a support seat 84, weights 85, and fixed pulleys 86. The sliding seat 7 is connected to two hooks 81 on both the front and rear sides. Each hook 81 is suspended by a hook 83. The hooks 83 are made of steel and have good strength and wear resistance. Each hook 83 is connected to a pull rope 82. The tail end of each pull rope 82 is connected to a support seat 84. Each support seat 84 has four stacked weights 85. The base frame 1 is rotatably connected to two fixed pulleys 86 on both the front and rear sides. Each pull rope 82 passes around an adjacent fixed pulley 86.

[0023] like Figure 1 and Figure 5 As shown, the stabilizing mechanism 9 includes a fixed ring 91, a stabilizing clamping ring 92, and a spring 93. The base frame 1 has two fixed rings 91 connected to the front and rear sides. The stabilizing clamping rings 92 are slidably connected to the front and rear parts of the fixed rings 91. The stabilizing clamping rings 92 are in contact with the adjacent pull ropes 82. The sides of the stabilizing clamping rings 92 that are close to each other are arc-shaped to facilitate fitting the shape of the pull ropes 82. The spring 93 is connected between each stabilizing clamping ring 92 and the adjacent fixed ring 91.

[0024] When it is necessary to test the horizontal push-pull force of the stepper motor 3, this device can be used. The base frame 1 is brought into contact with the ground. When the push force needs to be tested, the stabilizing clamping ring 92 is moved by hand, compressing the spring 93. Then, the hook 83 and the pull rope 82 are passed through the left-side fixing ring 91 and around the left-side fixed pulley 86, so that the hook 83 is hooked onto the hook ring 81 for fixation. Then, the stabilizing clamping ring 92 is released, the spring 93 rebounds, and the stabilizing clamping ring 92 moves in the opposite direction to return to contact the pull rope 82. The sides of the stabilizing clamping rings 92 that are close to each other are arc-shaped to easily conform to the shape of the pull rope 82. Then, according to the test requirements, a weight of appropriate weight is added. The weights 85 are stacked on the support base 84. The processor starts the motor 3 on the mounting base 2 via the control module. The mounting base 2 is L-shaped for easy support. The motor 3 drives the coupling 4 to rotate, causing the lead screw 5 to rotate. Under the action of the thread, the sliding seat 7 moves along the guide rod 6, thereby driving the hook 83, the pull rope 82, the support base 84, and the weights 85 to move, causing the fixed pulley 86 to rotate. The stable clamping ring 92 provides stable guidance. The hook 83 is made of steel, which has good strength and wear resistance, thus providing stable guidance for the pull rope 82 during testing, preventing the pull rope 82 from shifting or falling off, improving the stability of the test, and thus measuring the electrical... The thrust of motor 3 is then tested by increasing the number of weights 85. The value of the weights 85 is read to estimate the thrust of motor 3. After the thrust test, motor 3 is turned off, and the stabilizing clamping ring 92 is pulled to move. The spring 93 is compressed, and then the weights 85 and hooks 83 on the left are removed. Then, the stabilizing clamping ring 92 is released, the spring 93 rebounds, and the stabilizing clamping ring 92 moves in the opposite direction to reset. The above operation is repeated to hook the hook 83 on the hook ring 81. Then, motor 3 is reversed to make the coupling 4 rotate in the opposite direction, which makes the lead screw 5 rotate in the opposite direction. Under the action of the thread, the sliding seat 7 moves in the opposite direction, thereby pulling the hook 83 and the pull ring 81. The rope 82, the load-bearing seat 84, and the weight 85 move, causing the fixed pulley 86 to rotate, thereby measuring the tension of the motor 3. The number of weights 85 can then be increased to continue testing, and the values ​​of the weights 85 are read to estimate the tension of the motor 3. This allows for adjusting the number of weights 85 to test the push-pull force of the motor 3 under different load conditions. The operation is simple, facilitating a comprehensive evaluation of the motor 3's performance and maximum load capacity, improving testing efficiency and accuracy. After the test, the motor 3 is turned off, and the stabilizing clamping ring 92 is pulled to move, compressing the spring 93. Then, the weight 85 on the right and the hook 83 are removed, and the stabilizing clamping ring 92 is released, causing the spring 93 to rebound.The stabilizing clamping ring 92 is moved in the reverse direction to reset, and then the load-bearing base 84 can be placed.
