[0032] Please refer to Figures 1 to 4, this embodiment provides a fixture spring piece inspection fixture. The fixture spring piece inspection fixture includes a mounting plate 210, a test frame 220 and a pressure sensor 230. Among them, a carrier 211 is provided on the mounting plate 210, and the carrier 211 is configured to carry the fixture 110. It can be understood that when the fixture 110 is placed on the carrier 211, the spring piece 120 on the fixture 110 faces the test frame 220. The test frame 220 is slidably connected to the mounting plate 210. The test frame 220 is disposed opposite to the carrier 211. The test frame 220 can slide towards the carrier 211 and push against the spring piece 120 to deform it. The pressure sensor 230 is configured to detect the thrust exerted by the spring piece 120 on the test frame 220 when the test frame 220 pushes against the spring piece 120 to deform it, so as to detect the elastic force of the spring piece 120, and further be able to inspect the performance of the spring piece 120.

[0033] Specifically, in this embodiment, the spring piece 120 is U-shaped. When the carrier is placed on the carrier 211, one straight arm of the spring piece 120 is mounted on the fixture 110, and the other straight arm of the spring piece 120 is in a suspended state, and the suspended straight arm faces the test frame 220. The test frame 220 can move towards the carrier 211, so as to push against the suspended straight arm, and further cause the spring piece 120 to deform. During the process that the test frame 220 pushes against the spring piece 120 to make the spring piece 120 deform, the pressure sensor 230 can detect the elastic force of the spring piece 120, so as to be able to inspect the performance of the spring piece 120 according to the deformation amount of the spring piece 120 and the magnitude of the detected elastic force.

[0034] Based on the above, in this embodiment, the fixture 110 is limited by the carrier 211, and the spring piece 120 is pushed by the test frame 220 to make the spring piece 120 deform. Moreover, in this embodiment, the pressure sensor 230 is used to detect the elastic force of the spring piece 120, so as to accurately detect the value of the elastic force, and further improve the accuracy of the inspection.

[0035] In addition, in this embodiment, a round table 221 is provided on the side of the test frame 220 facing the carrier 211. The round table 221 can push against the spring piece 120, so that the test frame 220 can stably push against the spring piece 120. Moreover, for spring pieces 120 of different shapes, the round table 221 can push against them to deform. Therefore, the fixture spring piece inspection fixture in this embodiment can also be applicable to detecting spring pieces 120 of different shapes.

[0036] Further, a positioning member 213 is installed on the mounting plate 210. The positioning member 213 is located on the path along which the test rack 220 slides towards the carrier 211. That is, in this embodiment, when the fixture 110 is placed on the carrier 211, a positioning member 213 is provided between the carrier 211 and the test rack 220. The positioning member 213 can limit the moving stroke of the test rack 220, thereby preventing the elastic piece 120 from slipping and flying off between the test rack 220 and the fixture 110 due to excessive force. On the one hand, this further ensures that the fixture for inspecting the elastic piece of the fixture can accurately inspect the elastic piece 120. On the other hand, it can also prevent the elastic piece 120 from slipping and flying, which may pose a danger to the staff.

[0037] Specifically, based on the content mentioned above, the test rack 220 can move towards the carrier 211 until it abuts against the positioning member 213. During this process, the test rack 220 can push against the elastic piece 120 and cause the elastic piece 120 to deform. At the same time, the pressure sensor 230 can detect the change in the elastic force of the elastic piece 120, so as to inspect the performance of the elastic piece 120 according to the deformation amount of the elastic piece 120 and the magnitude of the detected elastic force.

[0038] Furthermore, the installation position of the positioning member 213 is adjustable. That is, in this embodiment, the fixture for inspecting the elastic piece of the fixture can adjust the installation position of the positioning member 213 corresponding to the shape and size of the elastic piece 120, so as to adaptively adjust the maximum moving stroke of the test rack 220. In other words, this embodiment can adaptively adjust the maximum thrust exerted by the test rack 220 on the elastic piece 120 according to the shape and size of the elastic piece 120, and control the maximum deformation amount of the elastic piece 120 during the inspection process, so as to accurately inspect elastic pieces 120 with different shapes and sizes.

[0039] As described above, in this embodiment, the positioning member 213 includes a positioning block 2131 and a locking bolt 2132. The positioning block 2131 is slidably connected to the mounting plate 210 along the arrangement direction of the test rack 220 and the carrier 211. The locking bolt 2132 is configured to lock the positioning block 2131 to the mounting plate 210 or unlock the positioning block 2131. Specifically, before the inspection, the staff loosens the locking bolt 2132 to unlock the positioning block 2131. Then, the staff can slide the positioning block 2131 on the mounting plate 210 according to the shape and size of the elastic piece 120 to be inspected, and specifically select the installation position of the positioning block 2131. After adjusting the position of the positioning block 2131, the staff can tighten the locking bolt 2132 to lock the positioning block 2131 to the mounting plate 210 to prevent the positioning block 2131 from moving due to being pushed by the test rack 220 subsequently.

[0040] In this embodiment, a chute 214 is provided on the mounting plate 210. The chute 214 extends along the arrangement direction of the test stand 220 and the stage 211. A protruding portion 21311 is provided on the positioning block 2131. The protruding portion 21311 is accommodated in the chute 214. When the staff loosens the locking bolt 2132 to unlock the positioning block 2131, the protruding portion 21311 of the positioning block 2131 can slide along the chute 214, thereby adjusting the position of the positioning block 2131. It can be understood that the chute 214 can guide the movement of the positioning block 2131, so as to ensure that the positioning block 2131 is located on the movement path of the test stand 220 before and after adjustment.

[0041] In addition, a slide rail 212 is further provided on the mounting plate 210. The test stand 220 is slidably connected to the slide rail 212 through a slider 222. The slide rail 212 can guide the movement of the test stand 220, so as to ensure that the test stand 220 can stably push against the elastic piece 120, and further ensure that the jig for inspecting the elastic piece of the hanger can accurately inspect the elastic piece 120.

[0042] Furthermore, a limiting platform 215 is provided on the mounting plate 210. The limiting platform 215 is located on the side of the test stand 220 away from the stage 211. The test stand 220 is slidably connected between the limiting platform 215 and the stage 211. The limiting platform 215 can limit the test stand 220, so as to prevent the test stand 220 from slipping off the mounting plate 210, and thus facilitate the staff to store the jig for inspecting the elastic piece of the hanger subsequently.

[0043] It should be noted that, compared with the dynamometer, the pressure sensor 230 detects the elastic force of the elastic piece 120 through electronic components and circuit design. Based on this, the jig for inspecting the elastic piece of the hanger in this embodiment further includes a display screen (not shown in the figure). The display screen is electrically connected to the pressure sensor 230 and is configured to display the detection result of the pressure sensor 230. That is, in this embodiment, the numerical value of the elastic force detected by the pressure sensor 230 is displayed through the display screen, so as to facilitate the staff to evaluate the maintenance effect of the hanger 110.

[0044] In addition, the jig for inspecting the elastic piece of the hanger further includes an information processing module (not shown in the figure). The information processing module is electrically connected to the pressure sensor 230 and is configured to store the detection result of the pressure sensor 230. That is, in this embodiment, the detection result of the pressure sensor 230 can be stored through the information processing module without the need for the staff to record, so as to save the time spent in the inspection process, and can also avoid the problem of data recording errors that are prone to occur in manual recording. In addition, the information processing module can also analyze the detection result to assist the staff in evaluating the maintenance effect of the hanger 110.

[0045] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
