Description

A kind of automobile cylinder cover measurement cubing
Technical field
The present invention relates to a kind of automobile cylinder covers to measure cubing, belongs to mechanical manufacturing field.
Background technique
With the increase of car ownership, the raising that vehicle dynamic quality and fuel economy are required.Cylinder cap is engine Chief part, it is very big to manufacture influence of the machining accuracy to engine quality, the relative position of crucial hole location and key The machining accuracy of size directly affects the performance of engine.Therefore, it is necessary to which the process in each hole of strict control, adds batch The position precision in the hole of work must strict inspection one by one.
Hole portion to be measured on cylinder cap is divided into deep hole or special shape hole, and existing manual measurement bar is put into deep hole when measuring deep hole Not necessarily can guarantee the verticality for being put into deep hole when measurement, it may appear that skew and protrude into too long or too short situation, influence to measure Precision.Ordinary measring tool once cannot cannot be accurately measured even to be measured when measuring special shape hole (such as cylinder cap upper half circular hole) Value causes duplicate measurements to influence measurement accuracy.In the prior art, main using manually micrometer, hole feeler gauge, three coordinates Measuring machine etc. is detected, although the measurement in hole on cylinder cap can be completed, its measurement efficiency is relatively limited, and can shadow The precision of detection is rung, existing automobile cylinder cover is mostly irregular body, there is inclined-plane and special hole more, and ordinary measring tool is difficult to precise and high efficiency Size of the acquisition to gaging hole, applicability and practicability receive limitation, and three coordinate measuring machine space hold is larger, and cost compared with Height, therefore there are the problems that cubing needed for one-time detection is more, and time of measuring is grown, it is difficult to meet market needs.
Common cubing when detecting more takes artificial loading, the material returned, will increase artificial burden in this way, slows down working efficiency, It is possible that workpiece falls the case where hurting sb.'s feelings, some meetings carry out feeding, the material returned using mechanical arm, but often snatch rate cannot It is guaranteed, the dynamics of handgrip is not easy to control and can cause to damage to workpiece surface.Can often it go out during usual feeding, the material returned The situation of existing workpiece skew, is unfavorable for the disengaging of workpiece and the detection and localization of next step, influences detection accuracy.
Summary of the invention
The present invention is improved for disadvantages mentioned above in the prior art, provides a kind of automobile cylinder cover measurement cubing, can To detect reliable multiple hole on the multiple faces of automobile cylinder cover (especially inclined-plane), data, high degree of automation, high-efficient simultaneously.
