Measurement gauge for disc cone height of air valve

Abstract

The invention discloses a measurement gauge for a disc cone height of an air valve. The measurement gauge comprises an air valve disc cone height measuring assembly, a base assembly part and a pressing part, wherein the air valve disc cone height measuring assembly comprises a locking screw, a lining, a pressing cap, a spring, a measuring sleeve, a limiting screw, a measuring head shaft and a dial indicator; the base assembly part comprises a base, a vertical plate, a slide block part and a V-shaped block assembly; the slide block part comprises a slide block seat, a locking screw, a first guide block, an adjusting screw, a second guide block, a slide block assembly and a fixed block assembly; the V-shaped block assembly comprises a V-shaped block seat and third inserts; the V-shaped block seat is fixed on a vertical plate under a circular placing position of an air valve to be detected and is provided with a V-shaped groove; the third inserts are embedded into the two sides of the V-shaped groove; and the pressing part comprises a support and a pressing assembly. The measurement gauge can be used for measuring vertical distance measurement values from disc cone surface gauge sections to disc end faces of the air valve to be detected with different rod diameters and different gauge diameters; and the quantity and the cost of the gauges are reduced and the timeliness of detection is ensured.

Description

technical field [0001] The invention relates to the field of detection of geometric characteristic items of valve products in the manufacture of internal combustion engines, in particular to a measuring and checking tool for the height of a valve disk cone. Background technique [0002] For the inspection of geometric characteristics of internal combustion engine valve products, any inspection involving the longitudinal distance from the section of the valve disc cone gauge to the end face of the disc can generally be measured by a general-purpose three-coordinate machine or a special inspection tool or a dial gauge for platform measurement. The former takes a long time to measure and uses a point probe. Because the diameter of the valve disc cone end surface is larger, the measurement results are somewhat controversial. For the ordinary special inspection tool used in the latter, the length of the inspection tool and the diameter of the positioning hole in the middle of the...

Problems solved by technology

But for valve products with many varieties, this approach is difficult, especially for valve products in the multi-plan design stage, because the valve design and change cycle is short, the design and production of ordinary special inspection tools is shorter

The existence of this contradiction is not conducive to quality control, and it is necessary to reinvent and design a measuring tool for the height of the valve disc cone.
