(54) DEVICE FOR REMOVAL OF BACKGROUND

one

FIELD: machine tool industry.

A device for chamfering is known, comprising guides on which the tool holder with the roller 1 is mounted with the possibility of reciprocating movement.

However, the known device does not provide the possibility of processing parts of different configurations. The purpose of the invention is to improve the quality of machining parts of various configurations.

To achieve the specified purpose / device, the tool holder is made in the form of a traverse and a column connected to it hinged on the rails, the device being equipped with a double arm and an additional roller, both rollers are mounted on the lever, and each lever arm is spring-loaded relative to the rails.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 - then

same, plan view; in fig. 3 - section A-A of FIG. 2

The device includes a plate 1 for mounting the part 2 with the drive 3, its rotation, the tool holder 4 mounted in the guides 5 with the possibility of reciprocating relative to the rotation of the part, and the pressure plate 6 connected to the pneumatic cylinder 7 with the possibility of free rotation.

The toolholder 4 consists of a column 8,

10, the lower end of which, embedded in the support 9, is installed in the guides 5. To the upper end of the column 8, the yoke 10 is hinged and hinged, bearing the mandrel 11 with the cutter 12. The yoke 10 is fixed in the working position of the scientific research institute by a torsion spring 13. The two shoulders are rigidly fixed on the column 8 a lever 14 with two supporting rollers 15 interacting with the side surface of the faceplate 1, configured to the workpiece 2 configuration. Each 20 arms of the two-arm boat 14 is spring-loaded in the direction of the axis of rotation of the part by springs 16.

The device works as follows.

The workpiece 2 is mounted on the faceplate 1 and fixed onto it by a pressure disc 6. The tool holder is fed to the part and, under the action of a torsion spring 13, the yoke 10 with the mandrel 11 and the cutter 12 is lowered into the working position. Include drive 3 rotation of the plate 1.

During the rotational movement, the plate 1 with its side surface acts on the support rollers 15 of the toolholder 4, forcing it to move along the guides 5, at the same time turning the column 8 on the lintel 9. Due to the two support rollers 15, the cutter 12 is constantly at a certain angle to the edges of the workpiece 2 In this case, the springs 16 hold both support rollers 15 in constant contact with the side surface of the plate 1.

After processing is completed, the presser disk 6 rises up, interacting with the crosspiece 10 and turns the tool holder 4 relative to the column 8. The processed part 2 is removed. This ends the cycle.

The use of the invention will allow chamfering of parts with straight sides in one step along the entire perimeter without additional manipulations. Due to the fact that during machining the cutter is constantly in a certain position relative to the machined edge, along the entire perimeter, the chamfer at all points is the same, besides, during machining the part does not touch the rubbing parts (except for the cutter) devices that could would leave traces or imprints on its surface.
