Description

(St) SEPARATE MACHINE WITH CHANGEABLE ANGLE

one

The invention can be used in the machine tool industry and is intended for cutting precision blanks at any angle.

Known cutting machine with a variable angle segments, on the basis of which mounted a movable body, carrying the spindle head with the drive of its supply and clamping device 1.

However, when cutting at an angle in a known cutting machine, large masses are moved, which reduces the rigidity of the machine and requires an increase in the power of the slew drive.

The purpose of the invention is to reduce the metal and simplify the design of the machine.

To achieve this goal in the proposed machine, the spindle headstock is provided with an axis and is installed with the possibility of rotation relative to the body around the geometric axis, CUTS

lying in the plane of the tool and parallel to the feed direction, and the housing is mounted on guides inserted in the base with the possibility of reciprocating movement by means of the feed drive.

FIG. 1 shows a machine, a general view; in fig. 2 is a view A of FIG. one. .

Claims (1)

The machine contains a stationary base 1 with a guide bar 2 along which the body 3 moves, carrying spindle heads k with the tool 5 The headstock is rotatably mounted relative to the base body 3 around the axis 6. The feed drive 7 headstock k is mounted on the base 1 and is connected body 3. The headstock k is rotated by means of a worm gear 8 and a rotation drive 9. On the base 1, a clamping device 10 is installed for positioning and clamping the workpiece 11, The machine works as follows. In the initial position, the body 3 is away from the clamping device 10. With the aid of the rotation drive 9 and the worm gearing 8, I rotate the axis 6 with the headstock mounted on it to the required segment angle. The workpiece 11 is fed to the cut and clamped in the clamping device 10. Under the action of the feed drive 7 (hydraulic cylinder), the body 3 with the belt k and the tool 5 moves to the workpiece along the guide 2 of the base 1. The workpiece 11 is cut at a predetermined angle. After cutting the workpiece, the body 3 retracts to its original position, the workpiece is unclenched, and the cut part of it is removed out of the machine. Simultaneously with the advancement of the remaining part of the workpiece 11 to cut, the headstock C rotates from the rotational drive 9 through the worm gear 8 to another angle of cut. Then the cycle of operation is repeated. Thus, in the proposed machine, the metal consumption is reduced and the design is simplified due to a decrease in the number of nodes that are movable when tuned to any angle of processing. . Claims of the invention A cutting machine with a variable cut angle, on the basis of which a movable body is mounted, carrying a spindle head with its feed drive and a clamping device, characterized in that, in order to reduce the metal capacity and simplify its design, the spindle head is equipped with an axis and is installed with rotation relative to the housing around a geometric axis lying in the plane of the tool and parallel to the feed direction, and the housing is mounted on guides inserted into the base vozvradno translational movement by supplying the actuator.
