Abstract
The invention discloses a rear oil seal leak test device, which is characterized in that the leak test device is pushed to the workpiece to be detected by grasping the handle, the entire leak test device is pressed against the outer edge of the workpiece by magnetic force, and the push rod moves horizontally to the right under the action of the cylinder Move, the sealing disc also moves along with it, and the sealing disc is in close contact with the rear oil seal seat under the guidance and positioning of its positioning pin, and the sealing ring seals around the rear oil seal seat under the force of the cylinder to form a sealing cavity. The leak test of the rear oil seal of the engine can be carried out through the air pipe joint by the air tightness instrument. Wherein: the push rod moves horizontally to the right in the leak test device under the action of the thrust of the cylinder, the cylinder pushes the push rod, and the sealing disc moves to the right, there is a lubrication-free bushing and a limit groove on the push rod, the method is easy , High 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...
