Problems solved by technology

The center position dimension of each control valve slice is a very critical dimension, if the deviation of this dimension is too large, the control valve slice will not be able to be assembled smoothly
Since the valve transmission shafts connecting adjacent control valves are relatively thin, and the number of control valves connected in series is often large, it is easy to cause the bending of the valve transmission shaft, resulting in a huge deviation in the center position of the control valves.
In the engine assembly workshop, there is no corresponding detection device that can detect the center position size of the control valve plate, which leads to the consequence that the assembly cannot be performed and affects the production

Abstract

The invention relates to a detection device for an engine part, in particular to the detection device for a variable section intake manifold control valve plate. The detection device comprises a base, wherein a fixing device for clamping the shaft end of a valve plate transmission shaft and a measuring device for measuring the control valve plate are arranged on the base; the measuring device comprises a vertical guide column and a plurality of sliding blocks slidably arranged on the vertical guide column; a ruler is arranged on the vertical guide column; a vernier used with the ruler is arranged on each sliding block; and a measuring part which is in contact with the valve plate transmission shaft and can extend to one shaft end of the control valve plate is also arranged on each sliding block. The shaft end of the valve plate transmission shaft is fixed through the fixing device, and the upper end and the lower end of the control valve plate are measured through the measuring part of the measuring device, so that the central position of each control valve plate can be obtained, and whether the control valve plate is qualified or not is judged, so as to guarantee the assembly quality and the smooth production process.

Description

technical field [0001] The invention relates to a detection device for engine components, in particular to a detection device for a control valve plate of a variable-section intake manifold. Background technique [0002] Engines with variable cross-section intake manifolds have better fuel economy and are now receiving more and more promotion. Each intake manifold of this engine is equipped with a control valve plate that can rotate to change the cross-sectional area of ​​the intake manifold, and all the control valve plates are connected between the adjacent two through the valve drive shaft Together, during engine assembly, all control valve sections are integrally installed into the intake manifold. The center position dimension of each control valve slice is a very critical dimension, if the deviation of this dimension is too large, the control valve slice cannot be assembled smoothly. Since the valve drive shafts connecting adjacent control valve plates are relativel...
