Description

"

The invention relates to metal cutting and can be used in various areas of the engineering industry.

The purpose of the invention is to increase the reliability and durability of the device, to improve the quality of the machined surface by dispersing the load transmitted to the power closure elements and reducing the vibration of the tool. I

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

The device consists of a body 1, a tool slider 2, a rezda 3, an elastic spring A, rollers 5-7, a copier 8 and a rod 9.

In the device case 1, the tool slider 2 freely moves with the cutter 3. B of the case bores 1

and the slider 2 is placed in the compressed state of an elastic spring A, the return force of which exceeds the radial component of the cutting force. The rollers 5 support the casing as it moves along the copier 8. The rollers 6 and 7, which copy the taper angle for the part 10, are connected by a rod 9, which is connected to the tool slider 2 by a pin joint.

The device works as follows.

When the longitudinal feed is switched on, the rollers 6 and 7 move on the surface of 5 copier 8, ensuring the specified

taper when machining the surface. Since the rod 9 remains always parallel to the plane of the coils of the spring 4, the forces transmitted to the instrumental slider 2 are evenly distributed along the coils of the spring and over the surface of the copier.

DEVICE FOR PROCESSING CONICAL SURFACE, comprising a housing, a slider spring-loaded relative to the housing with a cutting tool and a copy element and a copier, characterized in that, in order to increase its reliability and durability, the copy element is made in the form of two rollers of different diameters, interconnected by a rod inserted into the device, moreover, the ratio of the difference between the radii of the rollers to the length of the connecting rod is equal to the tangent of the taper angle. 1235660 2 and the slider 2 is placed · in a compressed state, an elastic spring 4, the return force of which exceeds the radial component of the cutting force. The rollers 5 support the housing as it moves along the copy 8. The rollers 6 and 7, copying the taper angle for the part 10, are connected by a rod 9, which is connected by a pin connection to the instrumental slide 2. The device operates as follows. When the longitudinal feed is turned on, the rollers 6 and 7 move along the surface 15 of the copier 8, ensuring a given taper when processing the surface. Since the rod 9 always remains parallel to the plane of the spring turns, there are 4, the forces transmitted to the tool slider 2 are distributed evenly along the spring turns and on the surface of the copier.
