Air tightness detection device of air compressor crankcase

Abstract

The invention discloses an air tightness detection device of an air compressor crankcase, which comprises a stable working block and a support frame, wherein two sides of the bottom of the stable working block are fixedly connected with the top of the support frame, the middle of the right side of the stable working block is fixedly connected with a vertical stabilizing column, and the top of theleft side of the vertical stabilizing column is slidably connected with a horizontal fixed stabilizing plate through a sliding block. The invention relates to the technical field of crankcase. According to the air tightness detection device of the air compressor crankcase, through united setting of a circular ring rotating sleeve, a sealing connecting rod and a sealing plate, the crankcase can notbe connected and sealed with the corresponding sealing plate, and one side of the crankcase, which is opened, is sealed directly by a fatlute layer in the sealing plate, thus the air tightness detection device is simple and convenient in operation, is suitable for large-scale detection, and solves the problems that when whether the crankcase is sealed is tested, the crankcase needs to the completely sealed by the corresponding sealing plate and then can be put into water for test, operation is tedious, which is not favorable for quick and large-scale maintenance.

Description

technical field [0001] The invention relates to the technical field of crankcases, in particular to an air tightness detection device for a crankcase of an air compressor. Background technique [0002] The upper crankcase of the crankcase is cast into one body with the cylinder block, and the lower crankcase is used to store lubricating oil and close the upper crankcase, so it is also called the oil pan. The oil pan bears little force and is generally made of sheet steel stamping. Its shape depends on the overall layout of the engine and the capacity of oil. An oil stabilizing baffle is installed in the oil pan to prevent the oil level from fluctuating too much when the car is jolted. There is also an oil discharge screw plug on the bottom of the oil pan, usually with a permanent magnet to absorb metal shavings in the lubricating oil and reduce engine wear. A liner is installed between the upper and lower crankcase joint surfaces to prevent lubricating oil from leaking. A...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an air tightness detection device for the crankcase of an air compressor, which solves the problem that when testing whether the crankcase is sealed, the crankcase needs to be completely sealed with a corresponding sealing plate before it can be put into water for testing. , the operation is more cumbersome, which is not conducive to the problem of rapid large-scale maintenance
