Abstract

Use, electrical engineering, machining of the internal discontinuous surfaces of the stators of electric motors The essence of the invention: on the mandrel there are two multidirectional threaded sections, and the abrasive element is made in the form of three tapered threaded bushings, one of which is made up of composite sectors established in its side part locks, and the other two are made with multi-directional conical working surfaces and are installed with In this case, the bee ends of the first one are provided with annular springs designed to interact with the sector of the composite hub. 6 Il.

Description

The invention relates to tools for finishing parts and can be used in electrical engineering, in particular in the final processing of the internal discontinuous surfaces of the holes of the stators of electric motors.

The purpose of the invention is to increase hone reliability when machining holes with intermittent surfaces.

FIG. 1 shows the proposed hon, a general view: in FIG. 2 shows section A-A in FIG. one; in fig. 3 - tapered bushing; in fig. 4 - section bB in FIG. 3 in FIG. 5 - a mandrel of a general view; FIG. 6 is a section along the line BB in FIG. five

Single-pass hon consists of a double-sided conical mandrel 1 made with longitudinal grooves 2, multidirectional intermittent threaded sections 3 and two annular grooves 4 and 5 on the outer surface of abrasive bearing

elements consisting of two integral conical sleeves 6 and 7, made with an internal thread 8 on the mandrel 1, 3-10-10 external cone with flips on the surface under the abrasive elements 10-12 hole 13 for the locking screws 14, as well as one composite bushings assembled from individual sectors 15-17 from the condition that their side surfaces 18 and 19 form locking joints, equipped with ring springs 20 and 21, designed to interact with sectors through the grooves 22 and 23, as well as from band clamps 24 and 25 put on through surfaces 26 and 27 s entangling sleeve 28.

Abrasive elements 29-31 are mounted on the surface of the composite bushing 28. In addition, the hon is provided with locking screws 14, 32 and 33, two rubber pads 34 and 35, which protect the threaded surfaces from clogging, and needles

ABOUT

Stokovik 36 for fastening the head with the spindle of the machine.

Before being used in a static state, all the sleeves 6, 7 and 28 are brought to the upper limit of the required size by external treatment, and further adjustment when the abrasive elements 10, 11, 12, 29, 30 and 31 are worn, is produced by using loose set screws 14, 32, 33 by moving the sleeves 6, 7 and 28 in the direction of increasing the cone, and after each wear the adjustment cycle is repeated as described above. Claims of the Invention A single-pass hoon containing an abrasive-bearing element fixed to the mandrel using radially mounted screws by possibility

and with longitudinal grooves of the mandrel, characterized in that, in order to improve hone reliability when machining openings with intermittent surfaces, two differently directed threaded sections are made on the mandrel, and the abrasive-bearing element is made in the form of three conical threaded knuckles, one of which is made from sectors installed in the central part of the sleeve due to the condition of their side surfaces of locking joints, and the other two - with oppositely directed conical working surfaces and us with both ends of the first, the hon provided with annular springs, arranged to cooperate with an integral sleeve sectors.

Claims (1)

Claim A single-pass hon containing an abrasive element mounted on the mandrel using radially mounted screws arranged to interact with longitudinal recesses of the mandrel, characterized in that, in order to increase the reliability of the hon when processing holes with discontinuous surfaces, two threaded threaded holes are made on the mandrel section, and the abrasive element is made in the form of three conical threaded sleeves, one of which is made up of sectors installed in the central part of the sleeve from the formation of lock joints by their lateral surfaces, and the other two with multidirectional conical working surfaces and are installed at both ends of the first, while the hone is equipped with ring springs designed to interact with sectors of the composite sleeve. .
