Description

This invention relates to instrumentation engineering.

The aim of the invention is to increase the measurement performance.

Figure 1 shows the device, a general view; figure 2 is the same, top view; on fig.Z - section aa on fig, 1.

The device includes a housing 1, made in the form of a pipe, a fixed support 2 placed on it, a movable support 3, made in the form of a square 4, a sleeve 5 with springs 6 m 7s a collar 8 connected by an adjusting screw 9. The sleeve 5 is spring-loaded on both sides by springs 6 and 7, abutting against the square 4 and the clamp 8, and on it are placed a pivot axis 10 with a bridge 1 1, on which two cylindrical stops 12 are installed symmetrically, a pointer pointer 13, matched with index 14, mounted on the square 4 along the axis housing pipes I parallel and flat345 050 ry

2 bridges 1 1 with the outer protruding surface of the reflector 28 and align the arrow pointer 13 with the index 14. After combining the position is fixed, the gauge 8, the nut head of the adjusting screw 9 move the angle bracket 4 until the vertical surface of the reflector 28 contacts it and 10 take the reflector diameter readings on a scale of 1 b and nonius 1 /. Moving the roller 23 of the rod 2 along the concave surface of the reflector 28

Movement of the movable support. The supports placed at the ends of the case, the bridge 12 of the bridge 11 are placed with a symmetrical sleeve mounted on the housing but with respect to the axis of the pipe of the housing 1. The measuring device is attached to the angle 4 attached to the angle bar 4 mounted on the sleeve of my 15 ruler. with a scale of 16, through a tick with two stops symmetrical every 100 mm on the housing 1 is located 30 relative to the axis of the housing, and the vernier 17 is counted. The scale 16 and the vernier 17 are the reference node.

Slider 18 is also located on housing 1, podpru: blued spring 19
