SU1602689A1 - Arrangement for enclosure of working zone of metal-cutting machine - Google Patents

Abstract

The invention relates to a machine tool industry, in particular, to devices for fencing the cutting area of machine tools, and can be applied, for example, in multi-operation machines with numerical program control and automatic tool change. The aim of the invention is to increase the reliability of protection of the working area by creating a closed fence. The device for fencing the working area consists of a U-shaped casing 1, a rotating casing 2, telescopic flaps 3 and a fixed vertical screen. The top plate of the telescopic plates is pivotally connected to the vertical screen, and the bottom plate is connected to the table of the machine. The device is equipped with a movable flap 15 designed to protect the auto-operator 10 from chips. 10 il.

Description

With simultaneous movement of the steel 5 up and horizontally, the flaps 3 enclosed between the walls of the U-shaped casing,. also fold up and move horizontally along with the table at the same time

For; replacing the machined part, the table 5 is moved to its original position, while the casing 2 opens with the hydraulic cylinder 16, turning around axis 17 to the left in position II (Fig. 1, thin lines). The tool mandrels 11 are replaced by an auto operator 10 between the spindle head 12 and the intermediate socket 13 with the non-rotating spindle in the initial position of the spindle head 12 and the table 5, while the new tool mandrel II (FIG. 10) is fed by the pneumatic cylinder 38 to the intermediate slot 13 with a fork

Device for fencing the working area of the machine tool, containing flat telescopic guards, the lower of which is fixed on the machine table, characterized in that, in order to increase the reliability of protection of the working area, the device is equipped with a vertical screen with a movable plate covering flat telescopic plates fixed on the frame P-shaped covers with a casing fixed on the table and installed with the possibility of interaction with the vertical screen and a swivel cover installed on the table with awn reacting with U-shaped housing, wherein the upper telescopic cue flat plate pivotally chance.

axial movement is associated with a vertical screen.
