Description

Technical Field

[0001] This application relates to the technical field of disc spring production, and in particular to a high-pressure control method applicable to disc springs of different specifications. Background Technology

[0002] Disc springs require a high-pressure step during production. For example, a disc spring high-pressure sorting device (publication number CN120551073A) uses a turntable with holes for accommodating disc springs. The rotation of the turntable moves the disc springs in the holes to the high-pressure device. However, when high-pressure is applied to disc springs of different specifications, especially those with large diameter differences, the disc springs tend to shift to one side of the hole as the turntable rotates, thus affecting the quality of the high-pressure disc springs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, one of the objectives of this application is to provide a high-pressure control method applicable to disc springs of different specifications, which has the advantages of being able to correct the position of the disc spring and being applicable to disc springs of different specifications.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: A high-pressure control method applicable to disc springs of different specifications employs a high-pressure device, which includes a high-pressure unit and a rotating disk. The rotating disk has receiving holes for accommodating the disc springs. The high-pressure unit includes a pressing rod and comprises the following steps. Confirmation steps: Confirm the difference between the diameter of the disc spring and the diameter of the receiving hole. If the difference is greater than the preset value, then perform the correction steps. Assuming the axis of the receiving hole and the axis of the lower pressure rod are collinear, the correction steps are as follows: rotate the rotating disk so that the receiving hole drives the disc spring to pass through the positive position first, then rotate the rotating disk in the opposite direction so that the receiving hole returns to the positive position. During the reverse rotation of the rotating disk, the position of the disc spring remains unchanged. Then, the observation steps are performed. Observation steps: Confirm the position of the disc spring in the receiving hole. If the position is correct, perform the strong pressure step; if the position is incorrect, perform the adjustment step. Adjustment steps: After adjusting the position of the disc spring to ensure it is in the correct position, perform the strong pressure step; Forced compression step: Apply strong pressure to the disc spring.

[0005] By adopting the above technical solution, when the difference between the diameter of the disc spring and the diameter of the receiving hole is large, the axial direction of the disc spring and the axial direction of the receiving hole will be significantly offset during the rotation of the rotating disk. Therefore, by rotating the rotating disk, the deviation between the axis of the disc spring and the axis of the pressing rod is reduced. Then, the position of the disc spring is confirmed. If the position of the disc spring is correct, that is, the distance between the axis of the disc spring and the axis of the pressing rod is within the error range, then strong pressure can be applied. If the position is incorrect, the position of the disc spring is adjusted to the accurate position before strong pressure is applied, thus making it applicable to disc springs of different specifications.

[0006] In a preferred embodiment, this application can be further configured such that, during the observation step, the dimensions of the disc spring are confirmed, and if the dimensions do not match the specifications of the disc springs currently being produced, the disc spring is rejected.

[0007] By adopting the above technical solution, when there is a deviation in position, there may be disc springs of other specifications or disc springs with large size deviations. Therefore, in the observation step, when the size is inconsistent, they are removed, thereby making the consistency of disc springs better.

[0008] In a preferred embodiment, this application can be further configured such that, in the adjustment step, an adjustment rod is used, which is concentrically set with the pressure rod, and a driving member is provided on the adjustment rod, which is used to contact the inner wall of the small end face of the disc spring and drive the disc spring to move.

[0009] By adopting the above technical solution, in use, the driving component contacts the inner wall of the small end face of the disc spring and drives the disc spring to move, thereby achieving the purpose of correcting the position of the disc spring.

[0010] In a preferred embodiment, this application can be further configured such that: the adjusting rod is provided with a gas flow channel, the driving member includes a flexible layer, the flexible layer covers the adjusting rod, the flexible layer and the adjusting rod form a closed space, and the closed space is connected to the gas flow channel.

[0011] By adopting the above technical solution, the flexible layer expands under air pressure during use, and the expansion rate is consistent in all directions, thus enabling the adjustment of the disc spring's position.

[0012] In a preferred embodiment, this application may be further configured to include a pressure detection step, in which the pressure in the enclosed space is detected, and when the pressure in the enclosed space reaches a preset value, the enclosed space is depressurized, and after the adjusting rod is reset, a pressure-reducing step is executed.

[0013] By adopting the above technical solution, when the pressure in the enclosed space reaches the preset value, it indicates that the inner wall of the small end face of the flexible component and the disc spring are in complete contact, thus indicating that the position correction of the disc spring is completed.

[0014] In a preferred embodiment, this application can be further configured such that the adjusting rod is located below the disc spring, and when the tip of the adjusting rod contacts the disc spring, the adjusting rod and the disc spring are in point contact.

[0015] By adopting the above technical solution, when the adjusting rod moves upward and comes into contact with the disc spring, since the contact is point contact with the disc spring and the contact point is the inner inclined surface of the disc spring, the probability of the disc spring being pushed out of the receiving hole can be greatly reduced.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1 and Figure 2 This application discloses a high-pressure control method applicable to disc springs of different specifications. A high-pressure device is used, which includes a high-pressure device 3, a rotating disk 2, and a support disk 1. The rotating disk 2 is provided with a receiving hole 21 for accommodating the disc spring. The receiving hole 21 is a through hole. The support disk 1 is located below the rotating disk 2 and is used to support the disc spring in the receiving hole 21. The high-pressure device 3 includes a pressing rod 31. Along the movement path of the disc spring, the central angle between adjacent stations is not greater than 90 degrees. For example, the unloading station where the disc spring is placed in the receiving hole 21, the high-pressure station where the disc spring is subjected to high pressure, and the height measuring station where the height of the disc spring is detected. When the axis of the receiving hole 21 and the axis of the pressing rod 31 are collinear, it is considered to be in the correct position. In this application, the definitions of concentricity, collinearity, etc., mentioned can be allowed to have errors in actual operation.

[0021] It also includes the following steps, Placement steps: Place the disc spring into the receiving hole 21, and set it concentrically with the receiving hole 21; Confirmation steps: Confirm the difference between the diameter of the disc spring and the diameter of the receiving hole 21. If the difference is greater than the preset value (the preset value can be set according to actual needs, such as setting the diameter of the receiving hole 21 to 1 unit, if the difference between the diameter of the disc spring and the diameter of the receiving hole 21 is 0.4 units, then it is greater than the preset value (0.3 units)), then execute the correction steps. Correction steps: Rotate the rotating disk 2 so that the receiving hole 21 drives the disc spring to pass through the positive position first. Then, rotate the rotating disk 2 in the opposite direction so that the receiving hole 21 returns to the positive position. (For example, if the rotating disk 2 rotates clockwise and the angle between the unloading station and the adjacent high-pressure station is 60 degrees, then the receiving hole 21 will rotate 65 degrees clockwise (at this time, the axis of the disc spring will be close to the axis of the lower pressure rod 31 or collinear with the axis of the lower pressure rod 31), and then rotate 5 degrees in the opposite direction to realize that the axis of the receiving hole 21 is collinear with the axis of the lower pressure rod 31). During the reverse rotation of the rotating disk 2, the position of the disc spring remains unchanged. Then, the observation step is performed. Observation steps: Confirm the position of the disc spring in the receiving hole 21 (i.e., confirm whether the axis of the disc spring and the axis of the pressing rod 31 are collinear). If the position is correct, perform the strong pressing step. If the position is incorrect, confirm the size of the disc spring. If the size is inconsistent with the specifications of the disc spring currently being produced, discard the disc spring. If the size is consistent with the specifications of the disc spring currently being produced, perform the adjustment step. Adjustment steps: After adjusting the position of the disc spring to ensure it is in the correct position, perform the strong pressure step; Forced compression step: Apply strong pressure to the disc spring.

[0022] In the adjustment step, an adjustment rod 4 is used. The adjustment rod 4 is raised and lowered by a cylinder or electric push rod. The support plate 1 is provided with an entry hole 11 for the adjustment rod 4 to extend into the receiving hole 21. The adjustment rod 4 is set concentrically with the pressing rod 31. The adjustment rod 4 is provided with a driving component. The driving component is used to contact the inner wall of the small end face of the disc spring and drive the disc spring to move.

[0023] The adjusting rod 4 is provided with a gas flow channel 41. The driving component includes a flexible layer 42 (such as rubber material), which covers the adjusting rod 4. The flexible layer 42 and the adjusting rod 4 form a closed space, which is connected to the gas flow channel 41. When the top of the adjusting rod 4 contacts the disc spring, the adjusting rod 4 and the disc spring are in point contact.

[0024] The adjustment process also includes a pressure detection step, in which the pressure in the enclosed space is detected. When the pressure in the enclosed space reaches the preset value (i.e., the disc spring is in the correct position, at which point the expanded flexible layer 42 expands under the pressure and comes into complete contact with the inner wall of the small end face of the disc spring, and the pressure value at this time is the preset value), the enclosed space is depressurized. After the adjustment rod 4 is reset (i.e., it does not protrude from the inlet hole 11), the strong pressure step is executed.

[0025] The implementation principle of this embodiment is as follows: During production, when the material is unloaded, the disc spring and the receiving hole 21 are set concentrically, and the included angle between adjacent workstations is no greater than 90 degrees. Therefore, the movement path of the disc spring is short, so that after the correction step, the disc spring is easy to be in the correct position. When the position of the disc spring is incorrect, the position of the disc spring is adjusted to make the position of the disc spring correct, so that it can be used for disc springs of different specifications.

[0026] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
