Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and in particular to an airtightness detection device for a bridge housing. Background Art

[0002] In the automobile manufacturing industry, the axle housing is an important part of the automobile chassis, and its air tightness is crucial to the driving performance and safety of the automobile; therefore, the axle housing needs to be strictly tested for air tightness during the production process.

[0003] Existing bridge housing air tightness detection devices are usually only capable of detecting specific types of bridge housings. However, with the current large number of vehicle types and rapid updates, the air tightness detection devices are unable to meet the detection needs of various types of bridge housings on the production line. Utility Model Content

[0004] The problem to be solved by the present application is that the existing bridge housing air tightness detection device is usually only capable of detecting a specific type of bridge housing and cannot adapt to the detection requirements of various types of bridge housings.

[0005] In order to solve the above technical problems, the present application provides an air tightness detection device for a bridge housing, including a frame for serving as a basic support, a clamping assembly with adjustable spacing arranged at the upper rear end of the frame to perform a closed clamping operation on the bridge housing, the clamping assembly is divided into a transverse clamping assembly and a longitudinal clamping assembly, the transverse clamping assembly is used to perform a closed clamping operation on both ends of the length direction of the bridge housing, and the longitudinal clamping assembly is used to perform a closed clamping operation on the upper and lower ends of the middle part of the bridge housing, and a lifting assembly is also arranged on the upper part of the frame for controlling the clamping assembly to perform vertical lifting operations to place the bridge housing in the water tank.

[0006] Since the detection device of the present application is designed with a clamping assembly and a lifting assembly, it can not only realize the closed clamping operation of the lateral ends and the longitudinal middle part of the bridge shell through the clamping assembly, but also realize the closed detection operation of the water inlet and outlet of the bridge shell through the lifting assembly, which solves the problem that the bridge shell air tightness detection device in the prior art can usually only perform detection on a specific type of bridge shell, and cannot adapt to the detection needs of multiple types of bridge shells.

[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. Example

[0016] This application relates to an airtightness detection device for a bridge housing, such as Figure 1 As shown, the detection device includes a frame 5 for serving as a basic support, a water trough 4 filled with water and used for bridge shell detection operations is arranged at the upper front end of the frame 5, and a clamping assembly with adjustable spacing for performing a closed clamping operation on the bridge shell is arranged at the upper rear end of the frame 5. The clamping assembly is divided into a horizontal clamping assembly 1 and a vertical clamping assembly 2 according to the clamping position and direction. The horizontal clamping assembly 1 is used to perform a closed clamping operation on both ends of the bridge shell in the longitudinal direction, and the vertical clamping assembly 2 is used to perform a closed clamping operation on the upper and lower ends of the middle part of the bridge shell. A lifting assembly 3 is also arranged on the upper part of the frame 5 for controlling the clamping assembly to perform a vertical lifting operation to place the bridge shell in the water trough 4.

[0017] The lifting assembly 3 includes a longitudinal slide rail 18, a transverse slide rail 6, a longitudinal slider 17, and a lifting cylinder 16. There are two longitudinal slide rails 18, which are symmetrically arranged in the vertical direction of the frame 5. The upper part of the longitudinal slide rail 18 is provided with a transverse slide rail 6 arranged perpendicular to it, and the back of the transverse slide rail 6 is symmetrically arranged with a longitudinal slider 17 slidingly connected to the longitudinal slide rail 18. At the top of the frame 5 is arranged a lifting cylinder 16 that can drive the transverse slide rail 6 to perform vertical lifting operations along the longitudinal slide rail 18. By means of the lifting cylinder 16, the transverse slide rail 6 is driven to drive the bridge housing to perform vertical lifting operations, thereby realizing the air tightness detection operation of the bridge housing entering and exiting water.

[0018] The transverse clamping assembly 1 includes a transverse slider 7, a transverse sliding seat 11, a transverse cylinder 8, a transverse suspension 9, and a transverse plug 10. There are three transverse sliding seats 11, all of which are slidably connected to the upper part of the transverse sliding rail 6 by means of the transverse slider 7. The transverse sliders 7 on both sides are arranged symmetrically. The upper part of the transverse sliders 7 on both sides is provided with transverse cylinders 8 for transverse clamping operations. The end of the transverse cylinder 8 is provided with a transverse suspension 9 connected thereto for realizing a sealing and supporting operation. The lower end of the transverse suspension 9 is provided with a transverse plug 10 for abutting against the two ends of the bridge housing to realize a sealing operation.

[0019] The longitudinal clamping assembly 2 includes a longitudinal cylinder 12, a longitudinal pressure frame 13, a longitudinal suspension 15, and a longitudinal plug 14. The longitudinal cylinder 12 for longitudinal clamping operation is arranged on the upper part of the middle transverse slider 7. The longitudinal suspension 15 for sealing and supporting the lower end of the middle part of the bridge housing is arranged on the upper part of the middle transverse slider 7. The longitudinal plug 14 for sealing the lower end of the middle part of the bridge housing is arranged on the upper part of the longitudinal suspension 15. In order to achieve effective longitudinal sealing of the bridge housing, a longitudinal pressure frame 13 connected to the longitudinal cylinder 12 for abutting against the bridge housing is arranged at the upper end of the middle part of the bridge housing.

[0020] When in use, the bridge housing that needs to perform airtightness detection operation is used to adjust the position of the cross clamping assembly 1 on the upper part of the cross slide rail 6, and then the cross cylinder 8 is used to drive the cross suspension 9 with the cross plug 10 to perform a closed clamping operation at both ends, so that the two ends of the bridge housing can be closed and supported. Then the longitudinal cylinder 12 is controlled to drive the longitudinal pressure frame 13 to abut against the middle upper end of the bridge housing, thereby applying pressure to the bridge housing, so that the bridge housing and the longitudinal plug 14 on the upper part of the longitudinal suspension 15 are sealed and abutted. In this way, the sealing operation of the two ends and the middle of various types of bridge housings is realized. In order to prevent the cross slider 7 from moving along the cross slide rail 6, bolts that can abut and lock with the cross slide rail 6 are arranged on the side of the cross slider 7, and then the cross slide rail 6 is driven by the lifting cylinder 16 to perform a vertical lifting operation along the longitudinal slide rail 18, so that the sealing detection operation of the bridge housing in and out of water can be completed.
