Description

The invention relates to a cleaning technique and can be used for sanding and hardening.

The purpose of the invention is to improve the quality of stripping.

Figure 1 shows the brush, a general view with a cut; Fig.2 - the same, with a bundle execution of a set of working elements, bottom view with a section: Fig. 3 - the same, with an annular design of a set of working elements, a bottom view with cuts and variants of the ends of the pushers in contact with working elements: Figures 4 and 5 are variants of the end of the pusher in contact with the working surface of the cam.

The end brush contains a housing 2 placed on the drive shaft 1 with axial displacement, spring-loaded relative to the shaft 1 by a spring 3. A set of working elements arranged therein, made in the form of beams 4 or an annular package 5 fixed in working elements fixed in the case 2 . The housing 2 has radial grooves 7 with pushers 8 located in them, contacting one end 9 with the working elements of the beams 4 (or ring package 5), and the other end 10 with the working surface of the cam 1 shaft I. The cam can be made removable and rigidly mounted on the shaft 1 (mount not shown). The diameter of the radial section of the cam 11 increases from the lower end 12 facing the work surface to the upper end 13. To ensure axial movement of the body 2 on the shaft 1 and ensure that the moment is transferred from the shaft 1 to the body 2, their connection is keyed or splined ( not shown). At the end 10, the pusher 8 is placed with the possibility of rotation of the ball 14. The brush works as follows.

about

The brush is rotated and moved along the surface to be treated (not shown) with Zealan tension. As long as the physicomechanical characteristics of the liquid to be removed do not exceed the allowable value, the brush works in the mode of easy cleaning, providing a high quality of surface cleaning. Increasing, for example, the height of liquids leads to an increase in stripping forces, which in turn leads to a displacement of body 2 upward along the driving vape 1. The working elements of beams 4 (or annular bag) come out of contact with the main surface to be treated and work only along the liquidating agents, which caused an increase in the cleaning force, carried out a cleaning process with increased cutting intensity due to the compression of the working elements by the pushers 8. If the working elements do not completely come out of contact with the main turn In this case, they are working on it with less strain, due to the axial lifting of the body 2, which also ensures that the tool working at this moment with an increased intensity of the cutting action does not deteriorate. After working with an increased cutting intensity, the tool removes liquids, which cause an increase in stripping forces, the body 2 is lowered, the working elements of the beams 4 come into contact with the main surface to be treated, and at the same time switch to light cleaning and thereby ensuring high quality treated surface. .

The expansion of the range of regulation is due to ensuring the independence of the choice of design, parameters of the cutting elements, the tool as a whole and the control law.

Improving the quality of stripping is achieved due to the combination of advantages created by the expansion of the range

WITH

adjustment while simultaneously lifting the working elements, ensuring that they come out of contact with the main surface to be treated, performing cleaning in the medium and coarse modes only for the corresponding liquids, subsequent (after removing them) processing the entire processing surface in the mode of light cleaning, ensuring an increase in the quality of processing . In this case, stripping takes place in the course of processing, depending on the state of the surface being treated, with an increased accuracy of adjustment.
