Abstract

The invention provides a device for measuring a distance from a body connection sleeve V-shaped groove center to a middle end face and relates to a measuring device. The invention aims to solve the problem that when an existing ordinary caliper measures distances from a body connection sleeve V-shaped groove centers to middle end faces in a batch, the positioning is not accurate, a measurement error exists, the production quality can not be controlled, the measurement efficiency is low, and the requirement of batch production is not satisfied is solved. The lower end of the fixed shaft of the device is installed in the center hole of a bow plate, a first spring sleeves the fixed shaft, a measurement plate sleeves the fixed shaft and is at the upper end of the first spring, a nut is screwed at the upper end of the fixed shaft to fix the measurement plate, two positioning pins are installed in one step hole through a second spring, the upper ends of the two positioning pins extend out of the upper end of the bow plate, the extending ends of the two positioning pins are connected to two nuts, the measurement plate is provided with a measurement center hole, and the left plate end face of the measurement plate is a sawtooth-shaped end face. The device is used for body connection sleeve detection.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for the distance from the center of a V-shaped groove of a body socket to the middle end face. Background technique [0002] Industrial body sockets with V-grooves (see figure 1 ) The part structure is widely used. The distance from the center of the V-shaped groove of the body joint to the middle end face is an important dimension to ensure subsequent assembly requirements. Conventional measurement methods are (see figure 1 ), use a caliper to measure the distance between two points (point a, point b) at the large end of the V-shaped groove, and then use a caliper to measure the distance between the middle end surface (C surface) of the body joint and one point (point a) at the large end of the V-shaped groove, a Half of the distance between point and point b, plus the distance from point a to surface C is the distance from the center of the V-shaped groove to the midd...
