Description

Technical Field

[0001] This utility model relates to the field of stepper motor positioning fixture technology, specifically a stepper motor high-temperature aging test positioning fixture. Background Technology

[0002] In fields such as intelligent manufacturing and automated equipment, stepper motors are core actuators, and their reliability in high-temperature environments directly affects the stability of system operation. Currently, high-temperature aging tests of stepper motors require connecting the motor to the load device to simulate actual working conditions. This requires positioning fixtures to not only securely install the motor but also ensure that the rotation axes of the motor and the load are coaxial, while also being adaptable to stepper motors of different sizes and specifications. However, existing positioning fixtures generally suffer from poor adaptability, leading to frequent disassembly and replacement of fixtures when changing different models of motors, reducing testing efficiency. Furthermore, during load testing, existing fixtures rely solely on manual visual inspection or simple shim adjustments, making it difficult to guarantee the coaxiality requirements of the motor shaft and the load shaft. This can easily cause vibration, noise, or even shaft wear during testing, thereby affecting the accuracy of test data.

[0003] Therefore, a positioning fixture for high-temperature aging testing of stepper motors is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for high-temperature aging testing of stepper motors. A first and second slide table on the base are slidably connected to a first slide rail. The guide post of the load assembly is inserted into the guide sleeve of the mounting plate for positioning. Combined with the first electric telescopic rod on the second slide table adjusting the height of the support platform, and the second electric telescopic rod driving the second slide rail and clamping plate to move, the coaxiality of the rotating shafts of the stepper motor and the load is ensured when their rotating wheels are connected via a coupling. This reduces vibration and shaft wear during testing, thereby improving the accuracy of the test data and solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base, a first slide table, and a second slide table. A first slide rail is fixedly installed on the upper surface of the base. Both the first and second slide tables are slidably connected to the first slide rail. A load assembly is provided at one end of the base. A rotating wheel is provided inside the load assembly. A mounting plate is fixedly connected to the upper surface of the first slide table. The mounting plate has a central hole and four sliding grooves. The four sliding grooves are evenly distributed around the central hole. A sliding block is slidably connected inside each sliding groove. A bushing is inserted into the surface of each sliding block. A support platform and a clamping plate are provided on the upper surface of the second slide table. A guide post is fixedly installed on the side of the load assembly near the mounting plate. A guide sleeve is fixedly installed on the mounting plate, and the guide post is inserted into the guide sleeve.

[0006] Preferably, the sliding block has an I-shaped cross-section, the sliding block is tightly fitted with the sliding groove, and the two sides of the sliding block are tightly fitted with the two sides of the mounting plate.

The upper surface of the support platform is provided with a V-shaped groove, and the included angle of the V-shaped groove is 90 degrees. Preferably, a guide rod is fixedly connected to the lower surface of the support platform, and the other end of the guide rod is inserted into the second slide and slidably connected to the second slide.

[0008] Preferably, a fixing plate is fixedly installed on the upper surface of the second slide platform, and a second electric telescopic rod is fixedly installed on one side of the fixing plate near the support platform.

[0010] Compared with the prior art, this utility model provides a positioning fixture for high-temperature aging testing of stepper motors, which has the following beneficial effects: The first and second slides on the base are slidably connected to the first slide rail. The guide post of the load component is inserted into the guide sleeve of the mounting plate for positioning. Then, combined with the first electric telescopic rod on the second slide to adjust the height of the support platform, the second electric telescopic rod drives the second slide rail and the clamping plate to move. When the stepper motor and the rotating wheel of the load are connected through the coupling, the coaxiality of their rotating shafts is ensured, reducing vibration and shaft wear during the test, thereby improving the accuracy of the test data.

[0014] 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.

[0015] Example: Please see Figure 1 - Figure 4 This embodiment of a stepper motor high-temperature aging test positioning fixture includes a base 1, a first slide 3, and a second slide 4. A first slide rail 2 is fixedly installed on the upper surface of the base 1, providing a sliding track for the first slide 3 and the second slide 4, allowing them to move along the first slide rail 2 on the base 1. A guide post 21 is fixedly installed on one side of the load component 5 near the mounting plate 7, which cooperates with a guide sleeve 22 fixedly installed on the mounting plate 7. The guide post 21 is inserted into the guide sleeve 22 to position the mounting plate 7, ensuring the relative positional accuracy between the mounting plate 7 and the load component 5, laying the foundation for ensuring the coaxiality of the stepper motor and the rotating wheel 6 of the load in the subsequent process. The mounting plate 7, which is fixedly connected to the upper surface of the first slide 3, is used to install the stepper motor. The first electric telescopic rod 12 on the upper surface of the second slide 4 can adjust the height of the support platform 13. The V-groove 14 on the upper surface of the support platform 13 has an included angle of 90 degrees to support the stepper motor. The height of the support platform 13 can be adjusted by the first electric telescopic rod 12 to facilitate the clamping plate 19 to clamp the stepper motor. The guide rod 15, which is fixedly connected to the lower surface of the support platform, is inserted into the second slide 4 and slidably connected to it to ensure the stability of the support platform 13 when moving up and down. The clamping mechanism consists of the fixed plate 16, the electric telescopic rod 17, the slide rail 18, and the clamping plate 19 on the second slide table 4. The electric telescopic rod 17 drives the slide rail 18 and the clamping plate 19 to move. The two ends of the connecting plate 20 are respectively hinged to the end of the clamping plate 19 near the fixed plate 16 and the surface of the fixed plate 16. When the electric telescopic rod 17 is activated, it drives the slide rail 18 to move, and the slide rail 18 drives the clamping plate 19 to move. Under the push of the connecting plate 20, the clamping plate 19 slides along the slide rail 17 to clamp the end of the stepper motor. The center point of clamping is coaxial with the rotation axis of the rotating wheel 6, further ensuring the coaxiality of the rotation axes of the two.

[0016] Four evenly distributed grooves 9 are formed on the surface of the mounting plate 7 around the central hole 8. The sliding block 10 connected to the groove 9 has an I-shaped cross-section and fits tightly with the groove 9 and its two sides fit tightly with the two sides of the mounting plate 7, ensuring that the sliding block 10 is stable and does not wobble when sliding in the groove 9. The surface of the sliding block 10 has a bushing 11 inserted. The appropriate bushing 11 and bolt are selected according to the size of the stepper motor mounting hole. When different models of stepper motors need to be installed, the position of the sliding block 10 in the groove 9 is adjusted according to the position of the stepper motor mounting hole so that the bushing 11 on the sliding block 10 is aligned with the mounting hole of the stepper motor. Then, the stepper motor is fixed to the mounting plate 7 by bolts passing through the bushing 11. This structure eliminates the need for frequent disassembly and replacement of tooling. Only the position of the sliding block 10 and the selection of the appropriate bushing 11 are needed to achieve stable installation of different motors, improving the adaptability of tooling and increasing testing efficiency. The working principle of the above embodiment is as follows: the first slide 3 and the second slide 4 on the base 1 slide along the first slide rail 2, which can adjust the relative position with the load component 5 to facilitate the installation of the motor. The guide post 21 of the load component 5 is inserted into the guide sleeve 22 of the mounting plate 7 for positioning to ensure that the positions of the two are accurate. When installing the stepper motor, the position of the sliding block 10 in the slide groove 9 is adjusted according to the position of its mounting hole. The appropriate bushing 11 and bolts are selected to fix the stepper motor on the mounting plate 7. The height of the support platform 13 is adjusted by the first electric telescopic rod 12 to make the height of the stepper motor appropriate. Then, the second slide rail 18 and the clamping plate 19 are moved by the second electric telescopic rod 17 to clamp and fix the end of the stepper motor.

[0017] The positioning fixture is set up inside the high-temperature aging test chamber. When using it, first select the appropriate bushing 11 according to the size of the mounting hole of the stepper motor and insert it into the sliding block 10. Place the stepper motor in the V-groove 14 of the support platform 13, start the first electric telescopic rod 12 to adjust the height, and then start the second electric telescopic rod 17 to drive the clamping plate 19 to move and clamp the stepper motor. Adjust the position of the sliding block 10 and fix the stepper motor with bolts. Push the first slide 3 and the second slide 4 to insert the guide post 21 into the guide sleeve 22 for positioning. Finally, connect the output shaft of the stepper motor to the shaft of the rotating wheel 6 through a coupling.
