Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring equipment, and particularly relates to an airtightness testing device for sealing rings. Background Art

[0002] In the existing sealing ring testing technology, a pressing mechanism is usually assembled on a frame. The sealing ring is sleeved in a test tube, and then, through the action of the pressing mechanism, it is firmly pressed into a circular hole preset on a test plate of a testing device, thereby sealing the circular hole and then conducting a test. During the test, gas is introduced to inspect the sealing performance. However, after the test is completed, the method of manually removing the test tubes one by one not only has low efficiency, but also increases the operation time and complexity. For this reason, we propose an airtightness testing device for sealing rings. Content of the Utility Model

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to the attached Figures 1-5 , a sealing ring airtightness testing device includes a frame body 1. The crossbar 2 installed on the frame body 1 divides it into a testing area and a material taking area. An edge for the testing disc to slide on the testing area of the frame body 1 is installed on the inner side wall of the frame body 1;

[0028] A jacking cylinder 4 is installed on the crossbar 2. A driving slider 41 that slides in the material taking area is connected to the output end of the jacking cylinder 4. A jacking slider 42 that cooperates with the driving slider 41 to jack it up is also installed in the material taking area. The contact surfaces of the driving slider 41 and the jacking slider 42 are inclined cutting surfaces, and the cutting surfaces of the driving slider 41 and the jacking slider 42 are arranged to abut against each other. The jacking cylinder 4 drives the driving slider 41, and the driving slider 41 slides and abuts against the cutting surface of the jacking slider 42, so that the jacking slider 42 jacks up. At least one jacking convex block 43 corresponding to the round holes on the testing disc is installed on the jacking slider 42. The jacking convex block 43 jacks up in the round holes of the testing disc, and ejects the test tube installed in the round hole, facilitating its removal.

[0029] Furthermore, flanges extending to both sides of the frame body 1 are installed on both ends of the driving slider 41 and the jacking slider 42. Strip-shaped grooves for the flanges of the driving slider 41 and the jacking slider 42 to slide are opened on both sides of the frame body 1.

[0030] In this embodiment, a sliding unit 3 distributed in the testing area is also installed on the crossbar 2. The sliding unit 3 includes a pair of parallel guide rods 31. A slider 32 is slidably arranged between the guide rods 31. A stop block 33 is arranged on the slider 32. The two sides of the slider 32 are recessed inward and are in contact and fit with the guide rods 31 to form a sliding fit. A groove is opened on the slider 32. A spring is arranged between the groove and the stop block 33 to make it elastically assembled. It is not directly fixedly connected to the testing disc, which is convenient for replacing the testing disc. After the testing disc is placed on the frame body 1, the stop block 33 on the slider 32 pulls the testing disc to realize sliding on the frame body 1. A sliding cylinder 34 is also installed on the crossbar 2. The output end of the sliding cylinder 34 is connected to the slider 32 to drive it to slide and cooperate along the direction of the guide rod 31. A sinking groove corresponding to the sliding cylinder 34 is opened on the jacking slider 42. When the sinking groove jacks up to the maximum height, the bottom of the sinking groove does not contact the sliding cylinder 34.
