Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc spring testing technology, specifically a thickness testing fixture for disc spring production. Background Technology
[0002] Disc springs, also known as Belleville spring washers, are conical discs that can be used individually, in series, or in parallel. They bear static or dynamic loads along the axial direction at the upper inner edge and lower outer edge. When compressed, they deform until they are flattened, storing energy as a live load.
[0003] Most current disc spring thickness detectors only measure a single point. This requires constantly changing the detection location, and they also cannot directly determine whether the disc spring thickness is uniform or meets the process requirements. Utility Model Content

[0020] 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.
[0021] like Figure 1-5As shown, this utility model provides a technical solution: a thickness detection fixture for disc spring production, including a base 1, two storage boxes 2 placed in the middle of the top of the base 1, a limit plate 102 set at the rear end of the base 1, a bracket 103 set at the rear end of the base 1, an infrared rangefinder 104 set at the end of the bracket 103 away from the base 1, four infrared emitters 105 set at the bottom of the infrared rangefinder 104, a mounting hole 106 is opened between the limit plate 102 and the bracket 103, the output shaft of a motor 3 is installed in the mounting hole 106, and a fixing block 3 is installed at the front end of the output shaft of the motor 3. 01. A slide rail 302 is provided in the middle of the fixed block 301. An annular slider 402 is installed in the slide rail 302. A placement plate 4 is connected in the middle of the annular slider 402. A fixing boss 401 is provided in the middle of the placement plate 4. A mounting hole 404 is provided at the bottom of the placement plate 4. An annular slider 403 is provided at the bottom of the placement plate 4. A slide rail 502 is connected to the outside of the annular slider 403. A fixing plate 5 is connected to the outside of the slide rail 502. Two mounting plates 501 are provided at the bottom of the fixing plate 5. A motor 6 is installed between the mounting plates 501. A mounting hole 503 is provided at the bottom of the fixing plate 5.
[0022] Furthermore, the infrared rangefinder 104, motor 3, and motor 6 are electrically connected to the controller 101.
[0023] The above technical solution allows the controller 101 to control the infrared rangefinder 104, motor 3, and motor 6.
[0024] Furthermore, slide rail 302 is an arc groove that is concentric with annular slider 402.
[0025] The above technical solution facilitates the rotation of the placement plate 4 by the motor 6, enabling a more comprehensive test of the disc spring.
[0026] Furthermore, the top of the placement plate 4 has a conical inclined surface structure.
[0027] The above technical solution facilitates the placement of the disc spring on the placement plate 4, and makes the conical inclined surface of the placement plate 4 coincide with the conical inclined surface of the disc spring.
[0028] Furthermore, the infrared emitter 105 remains parallel to the conical inclined plane.
[0029] The above technical solution ensures that the infrared rangefinder 104 detects the correct thickness of the disc spring.
[0030] Working principle: First, set the allowable deviation of the disc spring thickness in the controller 101. Then, place the disc spring on the placement plate 4 and start the infrared rangefinder 104 to detect the thickness of the disc spring. Then, start the motor 6 to rotate the disc spring so that the infrared rangefinder 104 can perform a more comprehensive thickness detection of the disc spring. The deviation of the disc spring thickness is judged by the feedback of the infrared rangefinder 104. If it is in line with the requirements, start the motor 3 to rotate the placement plate 4 to the right and place the qualified disc spring in the storage box 2 on the right. If it is not in line with the requirements, start the motor 3 to rotate the placement plate 4 to the left and place the unqualified disc spring in the storage box 2 on the left. Finally, repeat the above steps to detect the thickness of the remaining disc springs.
