Automobile full-bridge air tightness detection tool

Abstract

The invention discloses an automobile full-bridge air tightness detection tool. The tool comprises a support, a limiting device, a clamping device and a pressurizing device. After the limiting devicearranged on the support preliminarily limits the product, the product is clamped and fixed through the clamping devices arranged on the two sides of the product, communication between the pressurizingdevice and an inner cavity of the product is achieved, and detection of the air tightness of the product is completed by pressurizing the inner cavity of the product. The support comprises supportinglegs and an operation platform which are connected with each other, and fixing bases for being connected with the clamping device are arranged at the two ends of the operation platform respectively.The clamping device and the rotating device for clamping and rotating the product are arranged on the operating platform, so that the product is fixedly clamped, an inner cavity of the product is sealed, the air tightness of the product is convenient to detect, the working efficiency is improved, and the full-bridge quality is guaranteed.

Description

Technical field: [0001] The invention relates to the field of automobiles, in particular to an automobile full-bridge air-tightness testing tool. Background technique: [0002] The axle is an important part of the car. According to the different suspension structures, the axle is divided into two types: integral type and disconnected type. When non-independent suspension is used, the middle part of the axle is a solid or hollow center beam, and this kind of axle is an integral axle (full axle); Equipped with; the full bridge is especially common on trucks, it is like a huge barbell, the two ends support the body through the suspension system, it needs to bear a certain gravity and shear force, so there are strict standards for the quality of the full bridge ;The current full bridge is generally molded in one piece by casting. Due to the process, raw materials or other factors, penetrating air bubbles or gaps will be formed inside the full bridge, which seriously affects the...

Problems solved by technology

When non-independent suspension is used, the middle part of the axle is a solid or hollow center beam, and this kind of axle is an integral axle (full axle); Equipped with; the full bridge is especially common on trucks, it is like a huge barbell, the two ends support the body through the suspension system, it needs to bear a certain gravity and shear force, so there are strict standards for the quality of the full bridge ;The current full bridge is generally molded in one piece by casting. Due to the process, raw materials or other factors, penetrating air bubbles or gaps will be formed inside the full bridge, which seriously affects the quality of the full bridge. Is there any quality problem in the whole bridge?
