SU1458158A1 - Device for guarding the cutting zone of metal-cutting machine - Google Patents

Abstract

The invention relates to a machine tool industry, in particular, to devices for fencing a cutting area of multi-purpose CNC machines equipped with automatic flight changer devices. The aim of the invention is to improve the convenience of service due to the possibility of simultaneous rotation and longitudinal movement of the casing during loading and unloading raids. The device comprises a platform 14 movable in the longitudinal direction along the directions of the bridge 17, on which, by means of tapered rollers, a protective casing 1 is installed. On the table 3 of the machine concentric with the faceplate 2 mounted thrust bearing. On the outer ring of the thrust bearing is installed a ring cover with two fingers, which interact with the grooves of the half-ring bottom. Due to the interaction of the fingers with the grooves of the half-ring bottom, the platform 14 is moved together with the casing 1 and the working table 3 and the casing 1 is rotated on the platform 14 when the faceplate 2. 2 is turned.

Description

The primary rollers 12 and the toothed vein are 45, and then 13. The longitudinal movement of the casing, the casing 1 returns to the working position1, is accomplished by the longitudinal movement of the movable platform 14, on the arc direction of which 15 the rotary bearing cage 1 is mounted. 14 is provided with rolling bearings 16, mounted on two lateral sides of the platform and entering the grooves of the guide elements 17 serving to guide the movement of the casing 1 along the working table 3. The rotational drive of the casing 1 relative to the platforms we are 14 made as installed on the platform

reverse the rotation by 90. Set -: - The rotation of the change of pallets 6, turning on 180, turns on the machine and the subsequent processing cycle of the workpiece occurs according to the program hundred, nka. During processing of the workpiece due to the use of the fingers 21, the casing 1 and the working table 3 move together, which is provided by the feed drive in accordance with the processing program, while the platform 14 with the casing 1 is moved along a linear guide 17.
