[0001] This utility model relates to the field of stepper motor gear needle perpendicularity detection device, specifically a stepper motor gear needle perpendicularity detection fixture. Background Technology

[0002] Stepper motor gears are key components in the internal or external transmission system of a stepper motor, typically used to transmit the motor's torque to the load or to change speed and torque.

[0003] In the existing technology, a perpendicularity testing fixture is required to test the perpendicularity of the stepper motor gear pin. Generally, the perpendicularity of the motor gear pin is tested by a dial indicator on the perpendicularity testing fixture.

This operation is cumbersome. When inspecting stepper motor gear pins of other specifications, it is also necessary to change to a new tooling for fixing, which is inconvenient for personnel to use.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] Please see Figures 1-6 This utility model provides a technical solution: a stepper motor gear needle perpendicularity detection fixture, including: a dial indicator 6 and a base 2, a mounting frame 1 is provided on the base 2, a mounting shaft 7 is provided on the mounting frame 1, and a stepper motor gear body 11 is mounted on the mounting shaft 7. The stepper motor gear needle perpendicularity detection fixture includes: an adjustment mechanism 3 is provided on the mounting frame 1, the adjustment mechanism 3 is connected to the connecting frame body 4; the mounting shaft 7 is provided with an adjusting bolt 12, a pressing mechanism 13 and a contact plate 14, a spring spring 16 and a connecting rod 15 are provided on the side of the contact plate 14, the connecting rod 15 passes through a connecting hole 17 and is connected to the pressing plate 19, and a rubber pad 20 is provided on the side of the pressing plate 19.

[0025] In practical use, the operator can rotate the adjusting bolt 12 to bring the pressing mechanism 13 closer to the contact plate 14, allowing the connecting rod 15 to slide along the connecting hole 17, causing the pressing plate 19 to disengage from the storage slot 18. The two pressing plates 19 cooperate with each other to press the inner wall of the hole in the middle of the stepper motor gear body 11. This allows the stepper motor gear body 11 to be fixed on the mounting shaft 7. This allows the device to be adapted to fix different types of stepper motor gear bodies 11. The operator can rotate the adjusting mechanism 3 to move the connecting frame body 4 downward under the restriction of the limiting rod 5, so that the detection rod on the dial indicator 6 contacts the tooth of the stepper motor gear body 11. The perpendicularity is then checked using the dial indicator 6. This device is simple to operate and allows the operator to check the tooth of the stepper motor gear body 11 of more different specifications, improving the adaptability of the device. The operator does not need to use specific tooling to fix the stepper motor gear body 11, making the operation simple and convenient for the operator to use.

[0026] Example 2

[0027] To improve the adaptability of the device, a contact plate 14 is provided based on Embodiment 1. The contact plate 14 has a square plate structure, and a spring 16 is fixedly connected to the contact plate 14. The other end of the spring 16 is fixedly connected to the mounting shaft 7. The mounting shaft 7 has a thread and is threaded to the adjusting bolt 12. A pressing mechanism 13 is fixedly connected to the adjusting bolt 12. The pressing mechanism 13 has a conical structure. The operator can align the hole in the middle of the stepper motor gear body 11 with the mounting shaft 7 for installation, so that the inner wall of the hole in the middle of the stepper motor gear body 11 contacts the rubber pad 20. The operator can rotate the adjusting bolt 12, which, in conjunction with the threaded connection between the mounting shaft 7 and the adjusting bolt 12, compresses the spring 16, bringing the pressing mechanism 13 closer to the contact plate 14. The pressing mechanism 13 then presses the side of the contact plate 14. When the pressing mechanism 13 stops pressing the contact plate 14, the spring 16 can push the contact plate 14 back to its original position.

[0028] A connecting rod 15 is fixedly connected to the contact plate 14. The connecting rod 15 has a cylindrical structure and can slide along the connecting hole 17 on the mounting shaft 7. The connecting hole 17 has a circular hole structure. Two extrusion plates 19 are provided on the mounting shaft 7, and the extrusion plates 19 are symmetrical to each other. The connecting rod 15 slides along the connecting hole 17, and the extrusion plates 19 are disengaged from the storage groove 18. The two extrusion plates 19 cooperate with each other to extrude the inner wall of the hole in the middle of the stepper motor gear body 11. In this way, the stepper motor gear body 11 can be fixed on the mounting shaft 7. In this way, the device can be adapted to fix different types of stepper motor gear bodies 11, thereby improving the adaptability of the device and improving the use effect of the device.

[0029] The mounting shaft 7 is rotatably connected to the mounting bracket 1. The mounting bracket 1 is mounted on the base 2. The base 2 is rotatably connected to the adjustment mechanism 3. The threaded end of the adjustment mechanism 3 is threadedly connected to the threaded hole on the connecting bracket body 4. The connecting bracket body 4 is fixedly mounted with a dial indicator 6. The connecting bracket body 4 is slidably connected with a limit rod 5. The limit rod 5 is fixedly connected to the base 2. Personnel can rotate the adjustment mechanism 3 to make the connecting bracket body 4 move downward under the restriction of the limit rod 5, so that the detection rod on the dial indicator 6 contacts the tooth needle of the stepper motor gear body 11, and the perpendicularity is detected by the dial indicator 6.

[0030] The threaded hole on the mounting bracket 1 is threadedly connected to the threaded end of the adjusting mechanism 8. The other end of the adjusting mechanism 8 is rotatably connected to the connecting plate 9. A friction pad 10 is fixedly connected to the connecting plate 9. The friction pad 10 has an arc-shaped plate structure. The friction pad 10 and the connecting plate 9 can move under the limitation of the limiting groove 21 on the mounting bracket 1. The operator can rotate the adjusting mechanism 8 to make the adjusting mechanism 8 rotate along the threaded hole on the mounting bracket 1, and make the connecting plate 9 slide along the limiting groove 21, so that the friction pad 10 is no longer in contact with the mounting shaft 7. The operator can then rotate the mounting shaft 7 to make the stepper motor gear body 11 rotate. Through the above, the stepper motor gear body 11 can be inspected in other directions.

[0031] Example 3

[0032] Based on Embodiment 2, a rubber pad 20 is provided to improve the performance of the device. The rubber pad 20 has an arc-shaped plate structure and is fixedly connected to the extrusion plate 19. The extrusion plate 19 also has an arc-shaped plate structure and can be inserted into the storage groove 18 opened on the mounting shaft 7. The mounting shaft 7 can be used to install the stepper motor gear body 11. When the stepper motor gear body 11 is fixed, the rubber pad 20 contacts the inner wall of the hole of the stepper motor gear body 11, which can improve the stability of the stepper motor gear body 11 when it is fixed, improve the performance of the device, and improve the detection stability.

[0033] In actual use, the operator can rotate the adjusting bolt 12 to bring the pressing mechanism 13 closer to the contact plate 14, causing the connecting rod 15 to slide along the connecting hole 17. The two pressing plates 19 cooperate with each other to press the inner wall of the hole in the middle of the stepper motor gear body 11, fixing the stepper motor gear body 11 onto the mounting shaft 7. This allows the device to be adapted to fix different types of stepper motor gear bodies 11. The connecting frame body 4 moves downward so that the detection rod on the dial indicator 6 contacts the tooth needle of the stepper motor gear body 11. The perpendicularity is checked by the dial indicator 6, which makes it convenient for the operator to check the tooth needles of more different specifications of stepper motor gear bodies 11 through this device, improving the adaptability of the device. The operator does not need to use different tooling to fix the stepper motor gear body 11, making the operation simple and convenient for the operator to use.
