Problems solved by technology

With the rapid improvement of the technical level of the automobile and internal combustion engine industry, the engine has higher and higher requirements for the valve clearance. In order to obtain accurate clearance and control the cost, the engine factory adopts grouping for the key parameters of the valve tappet and the valve shim. The interchangeable assembly method requires that the height of the valve tappet inner circle and the height of the valve shim be supplied in groups, usually ±0.01mm. At present, the manufacturer adopts the method of manual measurement and grouping, which is easy to cause False detection, high measurement error rate, low efficiency and poor reliability
This is very unfavorable to the control of the engine valve clearance, and will also affect the power and emission of the engine

Abstract

The invention relates to an automatic separator for a valve tappet and a valve shim, which is controlled by a PLC (Programmable Logic Controller) control system. The automatic separator is characterized in that a material distributing system is arranged, a feeding system is arranged one side of one end of the material distributing system, a measuring system is arranged at the opposite side of one end of the material distributing system, and positioned behind the feeding system. A separating system is arranged behind the measuring system; the material distributing system and the separating system are respectively provided with a feeding conveyer belt and a separating conveyer belt which are arranged on the same plane; and the material distributing system, the feeding system, the measuring system and the separating system are connected into a whole. The automatic separator has higher repeatability, stability, measuring precision and measuring speed, is large in application range of a tested workpiece, can achieve the accurate and precise measurement and grouping on height of platform in the valve tappet and the valve shim, and is also suitable for on-line measurement.

Description

technical field [0001] The invention relates to an automatic measurement technology, in particular to an automatic measurement and automatic sorting instrument for valve tappets and valve shims. Background technique [0002] Valve tappets and valve shims are widely used accessories in the automobile and internal combustion engine industries. The shape of the valve tappets is cylindrical and bowl-shaped. The height of the inner garden platform and the height of the valve shim will affect the size of the valve clearance. With the rapid improvement of the technical level of the automobile and internal combustion engine industry, the engine has higher and higher requirements for the valve clearance. In order to obtain accurate clearance and control the cost at the same time, the engine factory adopts grouping for the key parameters of the valve tappet and the valve shim. The interchangeable assembly method requires the height of the valve tappet inner circle and the height of t...
