Description

Technical Field

[0001] This utility model relates to the field of rubber oil seal testing technology, specifically a tooling for testing the dynamic sealing performance of automotive rubber oil seals. Background Technology

[0002] Automotive rubber oil seals are elastic seals used to seal lubricating oil and prevent leakage. They are widely used in engines, transmissions, wheels, and other parts. The dynamic sealing performance testing fixture for automotive rubber oil seals is a device used to test the airtightness of automotive rubber oil seals after production.

[0003] Existing testing fixtures for the dynamic sealing performance of automotive rubber oil seals, such as the device for static airtightness testing of rubber oil seals disclosed in CN217032928U, have the advantages of not only testing the airtightness of oil seal products but also preventing engine failure due to poor airtightness of oil seals. However, this airtightness testing device is inconvenient for automatic positioning and feeding of rubber oil seals before and after testing, which makes it difficult to use. Therefore, we propose a testing fixture for the dynamic sealing performance of automotive rubber oil seals. Utility Model Content

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a tooling for testing the dynamic sealing performance of automotive rubber oil seals.

[0024] Example 1:

[0025] Combination Figure 1-4 As shown, this utility model provides a dynamic sealing performance testing fixture for automotive rubber oil seals, comprising: a testing instrument body 100 and a loading / unloading assembly 200; the testing instrument body 100 includes a testing seat 101 and a control box 102 respectively mounted on its upper and front ends; the loading / unloading assembly 200 includes a belt conveyor 201 fixedly mounted on one side of the testing instrument body 100, multiple sets of rubber oil seal testing parts 202 conveyed at the upper end of the belt conveyor 201, an open end 203 opened at one end of the belt conveyor 201, an extension platform 204 fixedly mounted on one side of the open end 203, a positioning push plate 205 movably mounted on the other side of the open end 203, and positioning rods 2 fixedly mounted at both ends of the positioning push plate 205. 06 and the blocking rod 207, the positioning box 208 is fixedly installed on one side of the detector body 100, the servo motor 209 is also fixedly installed in the positioning box 208, the top of the servo motor 209 is also fixedly installed with a lever 210, the rear end of the positioning push plate 205 is also fixedly installed with an electric push rod 211, the outer end of the electric push rod 211 is also fixedly installed with a fixing hoop 212, and the bottom of the fixing hoop 212 is fixedly connected to the upper part of the detector body 100. The detector body 100 is also provided with slanted openings 213 on both sides, and the detector body 100 is also provided with installation openings 214 on both sides. The collection box 215 is also movably installed in the installation openings 214. The extension platform 204 is located outside the detection seat 101.

[0026] Specifically, automotive rubber oil seals are elastic seals used to seal lubricating oil and prevent leakage. They are widely used in engines, transmissions, wheels, and other parts. The dynamic sealing performance testing fixture for automotive rubber oil seals is a device for testing the airtightness of manufactured automotive rubber oil seals. The belt conveyor 201 mounted on the outside of the testing seat 101 on the main body 100 of this testing instrument, along with the extension platform 204 and positioning push plate 205 mounted on both sides of the open end 203 of the belt conveyor 201, can automatically position and load the rubber oil seal test piece 202 conveyed on the belt conveyor 201 to the center of the testing seat 101. This automatic positioning and loading of the rubber oil seal test piece 202 before testing improves testing efficiency and convenience. Simultaneously, after the rubber oil seal test piece 202 is tested, the servo motor 209 inside the positioning box 208 can automatically unload the tested rubber oil seal test piece 202 via the lever 210 on its top, facilitating subsequent loading and testing of the rubber oil seal test piece 202. The electric push rod 2... The positioning push plate 205 driven by the 11 is mainly used for pushing the rubber oil seal detection piece 202 on the belt conveyor 201. The positioning rod 206 at one end of the positioning push plate 205 can be used to block one side of the rubber oil seal detection piece 202 on the belt conveyor 201 when it is not being pushed, and it can also be positioned at the outer end of the positioning box 208 during the pushing process to position and push the rubber oil seal detection piece 202 in the positioning push plate 205. The blocking rod 207 at the other end of the positioning push plate 205 is mainly used for pushing the rubber oil seal detection piece 202 in the positioning push plate 205. The belt conveyor 201 is blocked by other rubber oil seal test pieces 202. The extension platform 204 at one end of the open end 203 is mainly the feeding path of the rubber oil seal test pieces 202. The lever 210 driven by the servo motor 209 can rotate forward or reverse to push the rubber oil seal test pieces 202 in sections according to the test results of the rubber oil seal test pieces 202. After the rubber oil seal test pieces 202 are pushed, they are collected into the collection box 215 along the inclined openings 213 at both ends for the section collection of the rubber oil seal test pieces 202 after testing.

[0027] Working principle and usage process of this utility model:

[0028] During the airtightness test of the rubber oil seal test piece 202, the electric push rod 211 at the outer end of the belt conveyor 201 is first activated to drive the positioning push plate 205 at the front end to move forward. As the positioning push plate 205 moves forward, it pushes out the rubber oil seal test piece 202 located at the open end 203 inside the belt conveyor 201, allowing it to move forward along the extension platform 204. While the positioning push plate 205 pushes the rubber oil seal test piece 202 forward, the blocking rod 207 at one end blocks it at the open end 203, thus preventing the untested rubber oil seal test piece 202 from being conveyed inside the belt conveyor 201. Meanwhile, the positioning rod 206 at the other end of the positioning push plate 205, while moving forward, remains stationary... After the positioning box 208 is aligned, the rubber oil seal test piece 202 pushed by the positioning push plate 205 is positioned in the middle of the test seat 101. At this time, after the positioning push plate 205 is moved back by the electric push rod 211, the air tightness of the rubber oil seal test piece 202 on the test seat 101 can be tested. After the air tightness test of the rubber oil seal test piece 202 on the test seat 101 is completed, the control box 102 can be operated according to the test results to control the servo motor 209 to rotate forward or backward. Then, the tested rubber oil seal test piece 202 on the test seat 101 is pushed into the collection box 215 at one end for collection by the rotating lever 210 on the servo motor 209.
