The invention relates to a machine tool industry, in particular to a device for protecting guide machines,

The aim of the invention is to increase the effectiveness of protection by ensuring the discharge of chips in the place of its accumulation.

Fig, schematically shows the proposed device, side view | in Fig. 2, view A in Fig. 1j in Fig. 3, view B in Fig. J in Fig. 4, the device, view from the side of the groove with the table in the left position; in FIG. 5, the same with the right position of the table in FIG. 6, the device is a front view. on a flexible tape at the lower position of the scientific research institute table in FIG. 7, the same, with the upper position of the table; Fig. 8 shows a section B-B in Fig. 6; 6 and Fig. 9 shows a section D-D in Fig. 6; on - section dd in fig, 6 |. in Fig „P - the cut of E-E. to fig, 6; on Fig - device side view of a flexible tape with the lower forward position of the table; in FIG. 13, the same with the upper-raised position of the table; in FIG. 14, the same with the lower, retracted position of the table; FIG. 15 is the same. with the upper retracted position of the table; in FIG. 16, node T in FIG. 8 ,.

A device for protecting guides, for example, a cantilever-milling machine, contains a chute, within which lifting scrapers 2, ga harnessedly fixed on the fingers of 3 tables 4, move along the entire length. each scraper 2 has a rear thrust pin 5,

In order to effectively accumulate and dump chips in one place, chute 1 has a copying element 6, made in the form of successive arrows 7d hinged on rigid rulers 8 separated from each other by openings of size G, Each lifting scraper 2 is equipped with a groove of dimensions 3 and And it has the possibility of a translation through the arrow. From the arrow 7 and positioning with the reverse movement by the surfaces of the arrows 7, Trench I has a plan 1 and 9 and 10 on both sides of the inclined wall) 1 for fastening thereto, respectively, each from

bortovka 12 and 13 and the screen 14, which are made of flexible non-metallic tape. The upper part of the flexible tape is fixed on the drum 15, and the fastening is made with pressed flanging i 2 and i 3 to the screen 14. In this position, each selection is thin -1means varying angles oL and d, j of inclination towards the screen 14, which can have different angles

 A, 9 2 Pc of the slope with respect to the vertical plane, Drum 15 has an axis 16 with a CART a falling weight I7, a cable 18 and a block 9. designed to create a constant force, tension each screening 12 and 13 and screen 14, the lower part of which through the chute 1 is adjacent to the sled 20, installed under the aisle in: and the console 21, which, in turn, is movable on the frame 22 relative to the K and L ends, the drum 15 is mounted directly 7 with the spindle head housing 23 and is designed for winding on-. of the flexible tape, Table 4 has mobility along a sled 20 relative to the end Mj on the side of which a tank 25 is installed to receive chips.

The device works as follows.

Let the sled 20 on the cantilever 21, located on the frame 22, and also the table 4 on the sled 20 be in the middle position

In the process of high-speed cutting, for example (with an end mill, a piece of metal is cut off from the workpiece in the form of chips, which flies away from a high

and hits the screen 14, as a result of which the chips are scooped into the chute I, a portion of the flying away bang is struck at the flanges 12 and 13 and scoops into the gutter 1,

During the processing of the workpiece, the table 4 is moved forward and the chips from the chute 1 through. The EJH of the lifting scrapers 2 is discharged into the container 25, with each moving scraper 2 turning the hands 7 along the entire length of the groove 1 "

In the process of returning the table 4 to: the initial position, the lifting scraper 2 is removed from the stop pin 5 and slides along the surface of the arrow 7, as well as along the surface of the rigid ruler 8 to an opening with the value J where the scraper 2 descends.
