Description

The invention relates to the type of protective for rotating parts masks of cylindrical shrouds in which one part is fixed fixed to the machine and the other moves in the first along a circular arc.

In the proposed safety casing, intended to guard the American cartridge, faceplate or special devices, mounted on the spindle of a lathe or revolver machine tools, the movable part of the casing is equipped with a spring-loaded and axially movable shield.

In FIG. 1 is a side view of a guard for rotating parts of the machines; FIG. 2 is a front view of the casing; FIG. 3 - its top view; FIG. 4 is a cross-section of the housing according to aa of FIG. one; FIG. 5- same as bb of fig. one; FIG. 6 is the same in FIG. 7 is the same in dd FIG. one,

The main fixed part of the housing is the rear shield 1, which is fixed with the help of the holder 4 on the machine in place. It consists of two pieces of sheet iron folded in an arc, held together with

welding between two arcs of sheet metal (Fig. 1 and 4). In the gap inside the rear shield / the front shield 2 is installed, on the front part of which a sliding shield 3 is mounted. On the shield / the sleeve 8 is fixed, equipped with a ball 7, a spring 6 and a screw 5, which serves to install the front shield 2 in any position.

The front shield 2, together with the movable shield 5, can retract into the cavity of the rear shield, thus opening the cartridge or the tool. This is necessary, for example, when removing or putting on accessories or when installing a part.

Mobile shield 5 two rivets 70 is in the longitudinal groove of the bar 11, welded to the front shield 2 of the casing (Fig. 6). The spring 9 on the guide pins / 5 all the time pushes the movable plate 3 (Fig. 7) forward to the position indicated in the drawing.

Thus, the cartridge or device is closed all the time. When supplying the supor to the product, the supor rests in the movable shield 3 and pushes it in the axial direction.

When the suporta is retracted from the spring 9, the movable flap 5 is immediately depressed to its previous position, again closing the rotating parts.

The subject and the view takes it. . Cylindrical protective casing for rotating

parts of machines, in which one of the parts of the cylinder is fixed to the machine, and the other is made to move along an arc of a circle, characterized in that the moving part has a shield 8, spring-loaded and movable in the axial direction.
