Description

one

The invention relates to the field of surface hardening of machine parts by blasting and can be used in the production of various parts to increase their fatigue strength.

A device for shot blasting is known using control plates-witnesses, a deflection sensor and an electronic meter.

However, in a known device for assessing the quality of work hardening of parts, it is necessary to stop the blasting installation, which is not always convenient.

The purpose of the invention is to continuously monitor the intensity of work hardening of the parts. Drain, stop blasting at automatic shutdown when the required intensity of work hardening is reached.

This is achieved by the fact that the deflection sensor, together with the witness plate, is fixed in the shot-blasting chamber at the level of the surfaces of the parts being processed inside the hollow cylinder.

The drawing shows a diagram of the proposed device for blasting installations.

It consists of a plate-witness 1, a deflection sensor 2, an electronic meter 3, a workpiece 4 and a hollow cylinder 5.

The essence of the invention is that the plate-witness 1 is mounted on the fixed supports of the sensor body 2 deflections and pressed against them by means of a spring-loaded lever system cylindrical axes opposed to the supports. A metal rod rests against the fractional plane of the witness plate, the displacement of which corresponds to the maximum deflection of the witness plate 1.

The deflection sensor 2 readings are continuously recorded by the electronic meter 3 and recorded on its tape. When the deflection of the witness plate 1, corresponding to the achievement of a given intensity of the work hardening of the surface layer, the electronic meter 3 (through the executive relay) stops the operation of the shot blasting unit.

The amount of deflection of the plate depending on the intensity of the work-hardening of the surface layer of the hardened part is set in advance.

In order to ensure that the conditions for the treatment with shotgun parts 4 and the witness plate 1 are identical, together with the deflection sensor 2, it is fixed within the hollow cylinder 5 moving with the parts to be machined and having an opening in the dimensions of the witness plate.

Subject invention

: 1. A machine for shot blasting installations containing a witness control plate, a deflection sensor and an electronic meter, characterized in that, with little continuous monitoring of the intensity of work hardening and automatic shutdown of the blasting installation when the necessary hardening intensity is reached, the sensor deflections together with the plate -the witness is fixed in the shot-blasting chamber at the level of the surfaces of the parts being machined inside the hollow cylinder connected to Det, t and having 10H1 on the surface o spindle size but witness plate and which moves together with the workpiece in E.

2. Device but p. I, characterized in that, in order to allow free deformation, the witness plate is installed on the fixed supports of the deflection sensor cover and is pressed against them with pomon; ry arms and springs with movable axles, between which a measuring rod of the deflection sensor is installed, which is sonically with a shot-protected plate and a witness plate.
