Method for machining perpendicularity gauge

Abstract

The invention discloses a method for machining a perpendicularity gauge. A process for machining a movable gauge by the method includes 1), material preparation; 2), a lathing procedure implemented by lathe operators for lathing an outer circle and an inner hole and forming protective tables at two ends of the movable gauge; 3), a heat treatment procedure; 4), a sand blowing procedure; 5), a surface treatment procedure; 6), an inner hole grinding procedure; 7), an artificial aging procedure; 8), inner hole grinding; 9), a procedure for lathing off the protective tables at the two ends of the movable gauge; 10), a procedure for grinding two end surfaces of the movable gauge; 11), polishing sharp edges of a working portion of the movable gauge. The method has the advantages that the working step for forming the protective tables and the working procedure for lathing off the protective tables are added to the method, and forming ranges of flared openings are included within ranges of the protective tables, so that the problem that flared openings are formed at two ends of an existing movable gauge is effectively solved.

Description

technical field [0001] The invention relates to a processing method of a vertical gauge, which belongs to the field of mechanical processing. Background technique [0002] In the various forms of measuring tools required for actual production and processing, each measuring tool has its range of measurement applications. The gauge of the present invention can also measure the perpendicularity between the hole and the end face of the groove while measuring the accuracy of the hole. The verticality and size of the hole and the end face of the groove require high precision, so the precision required by the gauge used to measure their accuracy is also more precise, so its processing method is of great significance. If the conventional processing method is used, the bell mouth will appear at both ends of the working part of the movable gauge during finishing. The reason for the bell mouth is that the grinding tools (mostly grinding rods) are grinding the two ends of the movable ga...

Problems solved by technology

If the conventional processing method is used, the bell mouth will appear at both ends of the working part of the movable gauge during finishing. The reason for the bell mouth is that the grinding tools (mostly grinding rods) are grinding the two ends of the movable gauge during finishing. The head is reciprocating multiple times. Compared with the middle part of the movable gauge, the grinding stroke of the grinding tool is more and longer, so there is a bell mouth. This problem affects the measurement effect and makes the gauge unusable.
