Abstract
The invention discloses a rear oil seal leakage testing device, which is characterized in that a handle is grasped so as to push the leakage testing device to a workpiece to be detected, the whole leakage testing device is attached to the outer edge of the workpiece by a magnetic force, a push rod moves horizontally towards the right under the action of a cylinder, a sealing disc also moves along with the push rod, the sealing disc is attached to a rear oil seal base under guidance and positioning of a positioning pin thereof, the periphery of the rear oil seal base is sealed by a sealing ring under the action of the cylinder, a sealed cavity is formed, and leakage testing detection can be carried out on an engine rear oil seal by an airtight instrument through an air pipe joint. According to the invention, the push rod moves horizontally towards the right in the leakage testing device under the action of a pushing force of the cylinder, the cylinder pushes the push rod, the sealing disc moves towards the right, and the push rod is provided with a lubrication-free bushing and a limiting slot. The rear oil seal leakage testing device is easy in method, high in efficiency, safe and reliable.
Description
technical field [0001] The invention relates to the technical field of engine assembly and testing, in particular to a device for testing leakage of a rear oil seal during engine assembly. Background technique [0002] During the engine assembly process, the assembly process requires that after the engine rear oil seal is assembled, there must be no leakage. In the engine production line, the leakage test plays a vital role in ensuring the quality of the product. Usually people immerse the inflated test object in water and observe the generated bubbles to judge whether it is leaking. However, this method often misses detection, and there are also defects such as the need for drying and the inability to realize automation. Contents of the invention [0003] The present invention aims to overcome the defects in the above-mentioned prior art, and provides a device for testing the leakage of the rear oil seal, which uses an air tightness instrument (with a vacuum generator) t...
