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

Abstract

The invention provides an automobile engine rocker shaft oil hole penetration detection device with the following structure. The automobile engine rocker shaft oil hole penetration detection device includes a bracket, and further includes a feed box, a transferring mechanism and a detecting mechanism which are arranged on the bracket, the transferring mechanism is used for feeding a steel ball into a workpiece of a rocker shaft, and the detecting mechanism is used for detecting the speed of steel ball sliding out of the workpiece of the rocker shaft; the steel ball in the feed box enters a feeding pipe under the action of gravity, when a driving motor drives a transferring shaft to rotate to the opening end of an accommodating cavity and align with a feeding port, the steel ball is rolledinto the accommodating cavity, and the transferring shaft continues to rotate; and when the opening end of the accommodating cavity is aligned with the feeding port, the steel ball in the accommodating cavity enters the rocker shaft under the action of gravity and rolls out of a detection port, and a speed detection unit above the detection port detects the speed of the rolling steel ball to determine the penetration of an oil hole of the rocker shaft of an engine. According to the automobile engine rocker shaft oil hole penetration detection device, measurement is accurate, and operation is easy; and the steel ball for detection can be recycled, and the production cost is saved.

Description

technical field [0001] The invention belongs to the technical field related to automobile engines, and in particular relates to a detection device for the penetration of an oil hole of a rocker arm shaft of an automobile engine. 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 driving of the car, 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, which 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 are oil holes in the rocker shaft of the engine, which are used to lubricate the valve rocker arm when it rotates. Because the valve rocker arm keeps rotating, it is required to supply oil smoothly and smoothly to the oil hole in the roc...

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
