Inspection device for excircle boss height difference of thin-wall rotation-type part

Abstract

An inspection device for an excircle boss height difference of a thin-wall rotation-type part comprises a base plate. Two stand columns are arranged on the base plate, a transverse rod parallel to the base plate is arranged between upper ends of the two stand columns, a fixing support is arranged on the transverse rod, a dial indicator is connected with the position below the fixing support, and two same V-shaped blocks for placing parts are arranged on the base plate below the dial indicator along the direction of the transverse rod. The base plate and the stand columns are fixed through a bolt, the stand columns and the transverse rod are fixed through a bolt, the transverse rod and the fixing support are fixed through a bolt, and the fixing support and the dial indicator are fixed through a bolt. Wear-resisting hard blocks are arranged on positions of the V-shaped blocks contacted with the parts. The inspection device is convenient, rapid and efficient in detection process, greatly improves detection efficiency, greatly reduces labor intensity and operation difficulty of workers and simultaneously is high in detection accuracy.

Description

technical field [0001] The invention relates to a measuring tool for the height difference of an outer circular boss of a thin-walled rotary part. Background technique [0002] For the measurement of the height difference of the outer cylindrical boss of thin-walled rotary parts, most of them are measured by the outer eight-hole pneumatic measuring instrument and the outer diameter micrometer. Using the outer eight-hole pneumatic measuring instrument for measurement, the cost of the inspection tool is high, the measurement time is long, the measurement variation is large, the measurement is unstable, the operation is inconvenient, the skill level of the operator is relatively high, and the efficiency is relatively low; When measuring with a micrometer, the measuring force of the micrometer anvil is large, and the wall thickness of the part is thin. During the measurement, the micrometer anvil will squeeze and deform the outer circle of the part, which will affect the measure...

AI Technical Summary

Problems solved by technology

Using the outer eight-hole pneumatic measuring instrument for measurement, the cost of the inspection tool is high, the measurement time is long, the measurement variation is large, the measurement is unstable, the operation is inconvenient, the skill level of the operator is relatively high, and the efficiency is relatively low; When measuring with a micrometer, the measuring force of the micrometer anvil is relatively large, and the wall thickness of the part is thin. During the measurement, the micrometer anvil will squeeze and deform the outer circle of the part, which will affect the measurement accuracy.

Moreover, the measurements of the two methods are indirect measurements, and conversion is required to obtain the actual height difference

In the production of modern enterprises, due to the mass production of workpieces, when using existing inspection tools to measure these workpieces, it takes a long time, the measurement frequency is low, and the operation is inconvenient, resulting in low production efficiency, high production costs, and work. Labor intensity and other defects, so the existing inspection tools can no longer meet the needs of modern production
