Abstract

The invention relates to a control and measuring technique. The purpose of the invention is to increase accuracy and productivity. This is achieved by making the floating frame in the form of a rectangular triangle, one of the legs of which is an axis fixed in the housing with the possibility of rotation. At the apex of the opposite angle there is a spindle head, another spar head is fixed on the body. The measuring part is based on split heads. The heads, due to their elastic properties, self-align along the holes of the part, thereby moving the frame to the actual center-to-center distance, and the reading device records these deviations. 3 silt

Description

The invention relates to a control and measuring technique.

The aim of the invention is to improve measurement accuracy and productivity.

Fig, 1 shows the device, a general view; figure 2 - section aa in figure 1; on fig.Z - view B in figure 1.

The device for measuring center-to-center distances consists of a body 1, a floating frame 2, a split head 3 fixed to the body 1, and a split head 4 fixed on the frame 2.

The floating frame 2, made in the form of a rectangular triangle, is located in a plane perpendicular to the plane passing through the axes of the holes in the tested part. Clearance of the head 4 with the frame 2 makes an arc movement around the axis 0-0, which is a sliding bearing consisting of the axis 5 fixed to the housing, and the sleeves 6 and 7 pressed into the frame 2,

To ensure easy rotation, the frame 2 in the vertical direction rests on the thrust bearing 8. The part 9 is mounted on the case 1. The device is equipped with a reading device 10 fixed in the case 1, which contacts its sensitive element with the floating frame 2.

The device works as follows.

Depending on the parameters of the measured part, the device is adjusted to the measured dimension B. Split heads are selected according to the appropriate diameter and fixed: head 3 on the body, and head 4 on the floating frame

The device is adjusted according to the installation measure. After that, the checked part is installed on the device, which is based on two expansion heads. The heads, due to their elastic properties, are self-mounted through the holes of the part, thereby moving the rotating part
