Description

The invention relates to mechanical engineering technology and can be used in the final processing of holes.

The purpose of the invention is to expand technological capabilities by using tools on various types of machines.

The drawing shows a tool for machining a hole .10

The tool contains machining elements in the form of bars 1, fixed in holders x 2, mounted in the longitudinal direction in blocks 3,

central shaft and feed.

The tool works at once.

Before starting work, they fix to the tails of the shaft 8 in the spindle. Both rotation and rotation of the tool along the central rotation of the spindle of the shaft 8 through a gear 12-13-14 rotation in the direction opposite to

located in the slots of the housing 4. Push-t5 „y the central shaft.

The bodies 5 of the holders 2 are in constant contact with the profiled surface of the cam 6 by means of the rollers 7. The cam 6 is mounted on the central shaft 8.

Pushers 5, cam 6, rollers 7 and central shaft 8 form a transducer of rotational movement of the tool into reciprocating movement of holders 2. The working surface of cam 6 is made curvilinear, which provides each bar of the head with independent movement. Traces of abrasive grains of these bars form a grid of multidirectional intersecting scratches on the surface being treated, which characterize the roughness of the processed surface. An expansion cone 9 is freely mounted on the shaft 8, pushing the wheels 3 under pressure from the side of the pusher 10-. To return the cone to its original position after removing the load from the side of the pusher 10, a spring 11 is placed on the lower part of the central shaft.

To communicate the rotational movement of the housing 4 from the central shaft 8 on the shank of the central shaft and at the end of the tail part of the housing, gear teeth 12 and 13 are in contact with the intermediate gears 14 mounted rotatably on axes 15 mounted on holder 16, based on

central shaft and tool body.

The tool works as follows.

Before starting the operation, the tool is attached to the shank of the central shaft 8 in the spindle. The clip 16 is fixed from rotation, without limiting the movement of the tool with the clip along the Central axis. Turn on the rotation of the machine spindle. From the rotating shaft 8, the gear 4 rotates in a direction opposite to the rotation of the central shaft by means of a gear 12-13-14.

From the rotating cam 6, by means of the pushers 5, bars 1 on the holder x-2 reciprocate along the generatrix of the treated surface. The wear of the machining bars is compensated by moving down the cone 9. After the required size of the machined hole has been reached, the pressure is released from the pusher 10 and the spring 11 returns the cone 9 to its original position. The tool is taken out of the hole.

Thus, the creation of a kinematic connection of the central shaft of the tool with the body ensures the expansion of its technological capabilities, i.e. allows to use the tool in work on honing, drilling, milling, turning and other machines.
