Cylinder cover inclined plane processing depth detecting tool

Abstract

The invention discloses a cylinder cover inclined plane processing depth detecting tool comprising a reference plate with an outer end face in parallel with a cylinder cover inclined plane to be detected. A detection table installing hole is disposed on a position, corresponding to the cylinder cover inclined plane, on the reference plate. A detection table is disposed in the detection table installing hole and is vertical to the cylinder cover inclined plane. The outer end of the detection table is provided with an upper limit depth reference surface and a lower limit depth reference surface the height difference of which is equal to the cutting depth tolerance value of the cylinder cover inclined plane. When detection is performed, a hand touches the upper limit depth reference surface, the lower limit depth reference surface, and the outer end face of the reference plate. If the upper limit depth reference surface or the lower limit depth reference surface of the detection and the outer end face of the reference plate are in the same plane, or the outer end face of the reference plate is higher than the lower limit depth reference surface but lower than the upper limit depth reference surface, the cutting depth of the detected cylinder cover inclined plane is qualified. The cylinder cover inclined plane processing depth detecting tool is simple and reasonable in structure, easy to operate, high in detection efficiency and quality, and prevents misjudgment.

Description

technical field [0001] The invention relates to the field of automobile cylinder head processing, in particular to a measuring tool for measuring the depth of cylinder head bevel processing. Background technique [0002] The engine cylinder head is a very important part among the many parts of the engine. Many cylinder heads generally have inclined holes and inclined surfaces due to the needs of structure and functional layout. Some inclined surfaces are used as assembly reference planes, and the machining accuracy requirements are relatively high. If the deviation of the inclined surface machining depth is large, it will not only affect the assembly quality, This will affect the performance of the engine, and even cause the cylinder head to be scrapped, so it is necessary to equip corresponding and applicable process detection methods.

Problems solved by technology

Many cylinder heads generally have inclined holes and inclined surfaces due to the needs of structure and functional layout. Some inclined surfaces are used as assembly reference planes, and the machining accuracy requirements are relatively high. If the deviation of the inclined surface machining depth is large, it will not only affect the assembly quality, In turn, it will affect the performance of the engine, and in severe cases, the cylinder head will be scrapped, so it is necessary to equip corresponding and applicable process detection methods

[0003] However, due to the spatial geometric angle between the inclined plane of the cylinder head and the positioning reference, it is difficult to directly measure the cutting depth of the inclined plane with a general inspection tool. The traditional method is to use a three-coordinate machine to detect the machining depth of the inclined plane.

Three-coordinate machine detection is inconvenient, time-consuming and costly, which affects the normal operation of the production line. It is not suitable for routine detection of process control when the production cycle is fast.

However, in this way, inspectors need to accurately memorize the cutting depth values ​​of cylinder heads of various specifications

However, it is difficult for existing staff to memorize the above values ​​due to their different levels of proficiency

Therefore, this measurement method is easy to cause misjudgment, is not intuitive enough, and requires a probe head and a dial indicator, and the production cost is high

In addition, because each machined workpiece is allowed to have a certain tolerance, and the tolerance value also needs to be memorized by the inspectors, and judgments should be made based on the detected values. For those who cannot remember or confuse the above values, it is easy to cause Misjudgment
