Description

In the present invention, with regard to the device of a circular saw sawbind machine, 1) detachable with a groove and a ridge connected with a pin and nuts, a shaft provided with a groove for mounting and fixing a saw-hardened washer with a groove for free positioning around it saws, and 2) detachable distance rings of the respective device.

In the schematic drawing of FIG. 1 shows a general view of a shaft with saws mounted on it, detachable spacer rings, with a chamber for clamped spare NIL, with axes, nuts and ball bearings; FIG. 2, 3, 4 п 5-split distance ring, coupled with the help of radial protrusions and depressions, in various forms and in various projections: FIG. 6, 7, 8, 9 is the same ring when folded and in different projections; FIG. 10 and an AND-split distance ring consisting of two half-rings connected with each other by an oblique tooth, in the folded state, in two projections; FIG. 12-view distance ring between two saws; FIG. 13 is the same ring in expanded form, FIG. 14 is a side view of the two halves of a rim washer for saws, FIG. 15 - bolt for fastening these halves; FIG. 16 is a view of an extended shaft with a dug-out taken out and nuts moved, and FIG. 17th spiidel.

The shaft consists of two parts 1 and 2 (Fig. 1 and 2), one of which ends with a groove 3, and the other with a comb 4, and which are connected to each other with a cotter pin 16 (Fig. 1 and 17) and nuts 15 and 17 (Fig. 1 and 16); equipped with a pulley 5, the shaft rotates in ball bearings 6 and 6, of which the second is screwed to a slide bar 19, which, by unscrewing two bolts 20, can be moved to the right to disengage the shaft. Saws 9 are placed on the shaft, between which distal rings 10 are placed, its structure consists of half-rings, which are interlocked with ELI with an oblique tooth (Fig. 1, 10-13), or with the help of radial projections A or B on the same nipple to the cavity corresponding to it on the other (Fig. 2-9); saws with spacer rings are clamped on the shaft, on the one hand, with a nut 8 with a lock nut 7, on the other hand, a thrust washer 11 consisting of two halves (fig. 14) attached with a bolt 12 (fig. 15) on the groove 21 (Fig. 16) of the shaft 1; the other shaft undercut 13 serves to freely locate around it the central openings of the spare round NJL held by the stick with the help of fixed clamps 14, 14.

To decrease or increase the number of saws, the clamping nut is loosened and bolt 12 and thrust washer 11 are removed, after which the saws are removed or taken out of stock.

the working shaft and the intervals are taken up with washers inserted between the sawcaps, after which the washer and bolt are installed again and the nut is screwed.

To replace some saws with others, nuts 15 and 17 along thread 18 are moved to the right, pin 16 is removed and the right part 2 of the shaft with bearing 6 is moved to the right, after which the tools can be removed.

The subject of n and t a.

1. Spindle of a circular saw with a circular saw, characterized in that it is equipped with: 1) a recess 21 (Fig. 1, 17) for installing 12 halves of a stop for saws 11 (Fig. 1, 15) into it and fixing it with a bolt , 2) groove 13 (Fig. 1, 17) for free placement around it by the central holes zafig. Figure 12

I pass round springs, held by the bundle using fixed clamps 14, and 3) an attachment device with a spindle, for the purpose of changing saws, part 2 of the spindle, consisting of screw-on ends of connected parts equipped with a nose and a comb (Fig. 17) sovyvaem when omoombsh pin and 16 nuts 15, 17 (Fig. 1).

2. In the case of the spindle described in paragraph 1, the use of split distaptsponnyh rings 10 (Fig. 1), consisting each pz pair of half-rings, connected with each other using an oblique tooth (Fig. 1, 10-14).

3. In the case of the spindle described in p. 1, the use of detachable distance rings interlocked with each other using the radial protrusion A. or B (Fig. 2-4) on one of them and the cavity corresponding to it on the other.
