Description

Technical Field

[0001] This utility model relates to the field of pressure testing fixtures, and in particular to a spring sheet testing fixture with a pressure monitoring structure. Background Technology

[0002] In the field of spring sheet production and testing, testing the compressive strength of spring sheets is a crucial step in ensuring their reliability. The positioning accuracy and pressure monitoring accuracy of the testing fixtures directly affect the validity of the test results. As the application scenarios for spring sheets demand higher precision, the limitations of traditional testing fixtures are becoming increasingly apparent.

[0003] Traditional spring sheet testing fixtures have significant shortcomings: the positioning of the spring sheet relies heavily on manual adjustment, resulting in low lateral and longitudinal positioning accuracy and poor fixation stability. During testing, spring sheet displacement can easily lead to deviations in the pressure application position, affecting the accuracy of the test data. Furthermore, the fixture's fixing range cannot be flexibly adjusted according to the size and length of the spring sheet, resulting in poor adaptability and a tendency for the fixture to clamp onto the elastic working part of the spring sheet, causing testing interference or damage to the spring sheet. Utility Model Content

[0004] The purpose of this invention is to provide a spring sheet testing fixture with a pressure monitoring structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spring sheet testing fixture with a pressure monitoring structure, including a support platform, a working area on the support platform, positioning structures on both sides of the working area, and adjustment positioning fixtures on the other two sides of the working area.

[0006] As a preferred embodiment of this utility model, the positioning structure includes a mounting component, which is located on one side of the bottom of the support platform. A motor is installed inside the mounting component, and the output end of the motor is connected to a bidirectional lead screw. Movable frames are provided at both ends of the bidirectional lead screw, and the bidirectional lead screw is movably disposed within the movable frames. Movable slots are provided on both sides of the working area, and L-shaped connectors are movably disposed within the movable slots. One end of the L-shaped connector is connected to a positioning plate, and the other end of the L-shaped connector is threadedly connected to the bidirectional lead screw.

[0007] As a preferred embodiment of this utility model, the adjustment and positioning fixture includes a movable groove two and a U-shaped connector. The bottom of the U-shaped connector is movably disposed in the movable groove two. The U-shaped connector is provided with a screw hole, and a lead screw is threaded into the screw hole. A rotary joint is provided on the lead screw. A guide rail is provided on the inner side of the U-shaped connector, and a fixture positioning plate is movably disposed between a pair of guide rails.

[0008] As a preferred embodiment of this invention, a pressure testing machine is provided on one side of the support platform, and a pressure probe is provided at the working end of the pressure testing machine.

[0009] As a preferred embodiment of this invention, a monitoring panel is provided on the other side of the support platform, and the monitoring panel is electrically connected to the motor and the pressure testing machine.

[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: The motor drives a bidirectional lead screw to achieve precise lateral positioning. The lead screw drives the tooling positioning plate to complete longitudinal positioning, replacing manual adjustment and avoiding deviation in pressure application caused by spring plate displacement, thus ensuring the accuracy of the test.

[0011] Compared to traditional testing fixtures, this fixture can flexibly adjust the spacing between the positioning plates and the position of the fixture positioning plates according to the size of the spring sheet and the length of both ends, thereby accurately pressing the non-elastic parts at both ends of the spring sheet and effectively avoiding the problem of inaccurate testing caused by damaging the spring sheet.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] This utility model provides a technical solution: a spring sheet detection fixture with a pressure monitoring structure, such as... Figure 1As shown, it includes a support platform 1, a working area 2 on the support platform 1, positioning structures 3 on both sides of the working area 2, and adjustment positioning fixtures 4 on the other two sides of the working area 2.

[0016] like Figure 2 , Figure 3 As shown, the positioning structure 3 includes a mounting component 301, which is located on one side of the bottom of the support platform 1. A motor 302 is installed inside the mounting component 301. The output end of the motor 302 is connected to a bidirectional lead screw 303. Movable frames 304 are provided at both ends of the bidirectional lead screw 303. The bidirectional lead screw 303 is movably mounted in the movable frames 304. Movable slots 305 are provided on both sides of the working area 2. An L-shaped connector 306 is movably mounted in the movable slot 305. One end of the L-shaped connector 306 is connected to a positioning plate 307, and the other end of the L-shaped connector 306 is threadedly connected to the bidirectional lead screw 303.

[0017] like Figure 3 , Figure 4 As shown, the adjusting positioning fixture 4 includes a movable groove 401 and a U-shaped connector 402. The bottom of the U-shaped connector 402 is movably disposed in the movable groove 401. The U-shaped connector 402 is provided with a screw hole 403. A lead screw 404 is threaded into the screw hole 403. A rotary joint 405 is provided on the lead screw 404. A guide rail 406 is provided on the inner side of the U-shaped connector 402. A fixture positioning plate 407 is movably disposed between a pair of guide rails 406.

[0018] like Figure 1 As shown, a pressure testing machine 5 is provided on one side of the support platform 1, and a pressure probe 501 is provided at the working end of the pressure testing machine 5.

[0019] like Figure 2 , Figure 4 As shown, a monitoring panel 6 is provided on the other side of the support platform 1. The monitoring panel 6 is electrically connected to the motor 302 and the pressure testing machine 5.

[0020] In practice, the spring sheet to be tested is placed in the center of the working area 2. The motor 302 of the positioning structure 3 is started through the monitoring panel 6. The bidirectional lead screw 303 rotates to drive the L-shaped connector 306 to move. The positioning plates 307 on both sides move closer to the spring sheet until they fit the edges of the spring sheet, thus completing the lateral positioning.

[0021] The sliding U-shaped connector 402 moves along the movable groove 401, aligning the tooling positioning plate 407 with both ends of the spring sheet. The rotating rotary joint 405 drives the lead screw 404 to rotate, and the tooling positioning plate 407 descends along the guide rail 406, pressing the two ends of the spring sheet to complete the longitudinal positioning and ensure that the spring sheet does not shift during the testing process.

[0022] Set pressure test parameters such as pressure range and holding time on the monitoring panel 6, start the pressure testing machine 5, and slowly apply pressure to the surface of the spring sheet using the pressure probe 501 to detect the compressive strength of the spring sheet in real time.

[0023] The pressure testing machine 5 transmits the test data to the monitoring panel 6. The panel displays the pressure value change curve in real time. When the pressure reaches the preset threshold or the spring plate deforms beyond the standard, the monitoring panel 6 automatically issues an alarm, and the pressure probe 501 stops applying pressure and resets.
