Description

one

The invention relates to a means of active control of dimensions and can be used in the metalworking industry.

Devices are known for controlling the dimensions of parts with intermittent surfaces, such as flat and grinding of a contact type, comprising a housing, a measuring arm in contact with the surface of the part, a rotational drive of the measuring arm, an intermediate element through which movement from the actuator is transmitted to the measuring arm, and measuring a device for measuring the movement of said lever.

In the famous device, the great west measuring on K10nech: Nick about the brink ;; IB is reached by moving the measuring lever at a constant speed, exceeding some of them: he didn’t have an automatic vertical fall of the grinding wheel.

As a drive of rotation (displacement) of the gage lever in a known device, a small-size electric tangent with a constant number of revolutions n 1/20 rev / ln is used, and the intermediate element is rigidly connected by a drive and through a friction / clutch c. measuring lever.

One of the well-known devices is a great deal of effort: a small electric motor with a very low speed is rotated by the first output shaft, as well as the occurrence of a dynamic error in the instrument due to detachment of the measuring lever from the part and the moment of removal; AND.

The aim of the invention is to reduce the dynamic performance of the device and the complexity of its manufacture.

The goal is achieved by the fact that, in the available device, the drive is shaped like a slit-shaped generator, the chamber of which is deaf and equipped with a spring-loaded membrane that carries the stem, acting on the intermediate element, and two arms, simultaneously providing a force closure of the element lever with a controlled part, and the measuring device records the movement of the intermediate element.

trok-STVO is represented in the drawing.

It contains a corius / measuring lever, when checked with part

5 (details.) 3, the spacing element 4, and the lighting to the housing 1, mediOvO: M} 1.x P: gun 5, and the measuring device, consisting of a pneumoelectric-tactical differential readout device 6 and the measuring nozzle 7.
