Description

Miiiecnii.-ie device for automatic1; chescon grinding wheels, iiaiipuMtp, when working grinding machines in automatic. :) And 1: 1YAH. 1s osospechivat required vpai; Occ between the number of claiiKa clones and the work of the straightener.

In the proposed arrangement, this deficiency is solved by the use of three step finders, of which two are registrants of register and m; n; :; l |: 2 give impulses, which are obtained when processing products I1lif1) "yn .lp circles, and turn on the drive of the editing device; | after a single hour; the slime of the obtained imiuls is the third, and the third is perHCTpiiin-er 1 | ::; k ;; h / ;;; m; The impulses received during straightening, n, turn off the pr1; iodine Hp; icnnr (: c. to edit after a certain number of moves of alm; ::. ;;.: h: D1-ogavli and knock to further processing of products.

The Zshi Seeker is intended to count the counting: i ipulsosis, which is obtained at each course of the straightening device (o; pa; 5K i i with diamond).

The principle of operation of the device is as follows.

At each cycle of processing, the normally closed ones are closed at points 21-23 (Fig. 2) and the h.gsi coil is turned on;:;; -;) seeker lull through the chain 21-23-22.
