Technical Field

[0001] The utility model relates to the technical field of automotive fan actuators, in particular to a leak detection tooling for the front cover assembly of an automotive fan actuator. Background Art

[0002] Automotive actuators are devices used to perform specific functions in automotive systems. They are usually controlled by electronic signals to achieve vehicle automation and intelligence.

[0003] The current conventional leak detection tooling for the front cover assembly of an automotive fan actuator includes a liftable push terminal. The plug that matches the front cover is inserted into the jack on the front cover through the liftable push terminal. Since the volume of the downward-pressing push terminal and the plug is small and the contact area is small during the pushing process, manual lateral adjustment is required repeatedly to ensure the position correspondence among the push terminal, the plug, and the jack. Finally, air blowing and water injection are used to test the sealing performance of the front cover.

[0004] The current testing method still requires manual repeated adjustment of the docking position, with cumbersome processes and low efficiency, which is not conducive to large-scale batch detection.

[0005] Therefore, there is still a need for a leak detection tooling for the front cover assembly of an automotive fan actuator to solve the above problems. Summary of the Utility Model

[0006] The utility model provides a leak detection tooling for the front cover assembly of an automotive fan actuator to solve the above problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repetitive description will be omitted.

[0025] The words expressing positions and directions described in this utility model are all illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all such changes are included within the protection scope of this utility model.

[0026] Referring to Figures 1 - 3 , this utility model provides a leak detection tooling for the front cover assembly of an automotive fan actuator, comprising: a contact member 1, a support assembly 2, a sealing and blowing disc 3, and a telescopic member 4.

[0027] The contact member 1 has two parallel connecting rings 11, and the two parallel rings are connected by a plurality of rods 12. The contact member 1 is generally cylindrical, and the two connecting rings 11, and the shape of the connecting ring 11 is, for example, circular.

[0028] The support assembly 2 includes a base 21 and a connecting frame 22 connected to the base 21.

[0029] The top of the sealing and blowing disc 3 is used for sealingly connecting to the front of the front cover, and the cavity is used for blowing in gas. The top of the sealing and blowing disc 3 is a circular ring.

[0030] The fixed end 41 of the telescopic member 4 is connected to the top of the connecting frame 22. The mobile end 42 is used to push the connecting ring 11 at the top, so that the connecting ring 11 at the bottom abuts against the central position of the front cover after being guided by the conical surface on the front of the front cover, and pushes the front cover and the sealing support ring to be sealed and connected. During detection, first place the inner side of the front cover of the fan actuator facing up and the outer side facing down on the top of the sealing air blowing disc 3. Among them, the diameter of the air blowing disc is smaller than that of the front cover, so that the front cover can overlap on the top of the air blowing disc. Then, the mobile end 42 of the telescopic member 4 drives the abutting member 1, so that the abutting member 1 is on the inner side of the front cover, and under the drive of the inclined horn-shaped inclined surface on the inner side, the position in the horizontal direction is automatically corrected until it is completely positioned. The mobile end 42 of the telescopic member 4 continues to drive the abutting member 1 to move down, and pushes the front cover to be sealed and connected to the sealing air blowing disc 3. Insert the corresponding plug of the front cover at the opening of the front cover, introduce gas, observe whether there is gas jetting, determine the sealing performance between the plug and the front cover, and immerse it in water. When the water submerges the plug and there is no bubbling, there is no leakage at other positions either, meeting the sealing requirements. It can reduce the steps of manual positioning, improve the detection efficiency, and in the subsequent sealing detection, it is convenient to directly observe the sealing detection result of the front cover through the rod 12 between the connecting rings 11.

[0031] In one embodiment, a sealing ring is connected to the top of the sealing air blowing disc 3. The material of the sealing ring can be a silicone ring or a rubber ring, and the sealing ring is sealingly connected to the top of the air blowing disc.

[0032] In one embodiment, an air vent 31 for connecting an external air supply device is provided inside the sealing air blowing disc 3. The external air supply device is connected to the outside of the air blowing disc through a pipeline, and the gas enters the inside of the sealing air blowing disc 3 through the air vent as the detection air pressure.

[0033] In one embodiment, the material of the support assembly 2 is profile plastic steel. After inspection, the support assembly 2 made of profile plastic steel can effectively advance and avoid damage to the surface of the workpiece to be detected.

[0034] In one embodiment, the connecting frame 22 includes a vertical plate 221 and a top plate 222. The top plate 222 is fixedly connected to the top of the vertical plate 221, and a through hole for the mobile end 42 to pass through is provided on the top plate 222. Among them, the bottom of the vertical plate 221 can be fixed to the base 21 by welding, the top is welded to the top, and the vertical plate 221 is located away from the sealing air blowing disc 3, providing sufficient operating space for the staff.

[0035] In one embodiment, an installation groove 32 is formed at the top of the sealing air blowing disc 3 for embedding the sealing ring. The installation groove 32 is an annular groove, and the depth of the groove is less than the diameter of the seal, so that part of the top of the seal can protrude after being connected in the installation groove 32. Designing the installation groove 32 can effectively prevent the sealing ring from falling off, improve the sealing test effect after docking the front cover, and avoid the phenomenon of false measurement affecting the measurement result.

[0036] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principle and purpose of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
