A detection device for the oil hole penetration of the rocker arm shaft of an automobile engine

Abstract

The invention provides a device for detecting the oil hole continuity of a rocker shaft of an automobile engine with the following structures. The device comprises a holder, a material tank arranged on the holder, a material rotating mechanism and a detection mechanism. The material rotating mechanism is used for feeding steel balls into a rocker shaft workpiece. The detection mechanism is used for detecting the speed of the steel balls sliding out of the rocker shaft workpiece. The steel balls in the material tank enter a feeding pipe under the action of gravity. When a driving motor drives amaterial rotating shaft to rotate to the opening end of a containing cavity and to align with the feeding inlet, the steel balls roll into the containing cavity, and the material rotating shaft continues to rotate; when the opening end of the containing cavity aligns with a material conveying inlet, the steel balls in the containing cavity enter the rocker shaft under the action of gravity, and rolls out from a detection port; and a speed detection unit above the detection port detects the speed of the steel balls rolling out to determine the oil hole continuity of the rocker shaft of the engine. The detection device arranged in such way is accurate in measurement and easy to operate, the steel balls used for detection can be repeatedly utilized, and the production cost is saved.

Description

technical field [0001] The invention belongs to the technical field related to automobile engines, in particular to a detection device for oil hole penetration of rocker shafts of automobile engines. Background technique [0002] With the development of society, cars are becoming more and more popular as a convenient means of transportation. As one of the most important components in the car, the car engine provides power for the car to drive, and the rocker shaft of the car engine is an important part of the car engine. It is used to install the valve rocker arm. The valve rocker arm is mainly used to tighten the valve core and adjust the valve clearance. The valve rocker arm rotates on the engine rocker arm shaft. There is an oil hole in the rocker arm shaft of the engine, which is used to lubricate the rocker arm of the valve when it rotates. Since the rocker arm of the valve rotates continuously, the oil hole in the rocker arm shaft of the engine is required to supply oi...

AI Technical Summary

Problems solved by technology

If there are burrs, defects or unevenness in the oil hole, this will affect the supply of lubricating oil, causing the valve rocker arm to make noise when rotating due to oil loss, and it is easy to cause the inner wall of the valve rocker arm installation hole to wear, resulting in the use of the valve rocker arm. Reduced lifespan

Therefore, the oil hole penetration test must be carried out before the installation of the rocker arm shaft of the automobile engine, and the oil hole penetration test of the prior art is generally a manual test, that is, one end of the main shaft oil hole is manually inserted into lubricating oil, and then the lubricating oil is checked. Whether it can flow out smoothly, so as to determine whether the inner wall of the oil hole in the rocker shaft is smooth, but the efficiency of manual testing is low, and the test cost is relatively high; moreover, if there are burrs in the oil hole of the rocker shaft, it cannot be accurately tested. The installation of defective products on the engine is likely to cause rapid wear of the engine and affect the life of the engine
