Description

one

The invention relates to the processing of metals with chip removal and can be used on horizontal boring machines for surface treatment with a curvilinear generatrix.

A device for turning non-circular profiles is known, in which the copier is made along a constant radius curve and is associated with a slider carrying the tool holder 1.

This adaptation is closest to the invention in its technical essence and the achieved result.

However, in a known adaptation, the transition from one profile to another is determined by the number of rollers, which makes it difficult to retool the device.

The purpose of the invention is to facilitate readjustment of the device.

The goal is achieved by the fact that the device is equipped with a carrier sleeve placed in a stationary housing rotatably, in which a slider with a tool holder is mounted. The copier is fixedly mounted on the body and interacts with the copying probe attached to the slider. Copier is replaceable.

FIG. 1 shows the described device, a longitudinal section; on

FIG. 2 is a view along arrow A in FIG. one; on fng. 3 is a section BB in FIG. 2

In the housing 1 of the device, the driving sleeve 2 is mounted and fixed rotatably. On the carrier hub 2, guides 3 are fixed with grooves in which a slider 5 is mounted through the rolling elements 4. A screw 6 with a nut 7 and a spring 8 is placed in the latter. One end

screw 6 enters the recess of the slider 5, and the other into the sleeve 9 fixed in the hub carrier 2. The slider 5 has T-shaped grooves 10 in which bolts 11 are mounted to fasten the bar 12 with the tool holder 13. To the slider 5 a copying probe is attached 14, in contact with a cam 15 fixed to the housing I.

Widget-carrier 2 has grooves 16 and 17, which includes a finger 18, fixed

mounted on the spindle of the machine body 19. The cutter 20 is fixed in the tool holder 13 by a screw 21.

Adaptation works as follows.

The copier 15 is fastened to the housing 1, which corresponds to the shape of the surface of the workpiece, and the copying probe 14 to the slider 5. Bolts 11 installed in the T-slots 10 of the slider 5 fasten

bar 12 with tool holder 13 under times. . "..

. ,; .-, 24279 I measures the workpiece. The required force of pressing the probe 14 to the copier 15 is adjusted by a screw 6 and a nut 7. The assembled fixture is fastened to the fixed face of the boring machine, while the finger 18 fits into the grooves 16 and 17 of the carrier sleeve 2. Thus, the sleeve 2, together with the slider 5 fixed on it, the tool holder 13 with the stylus 14 through the finger 18 and the body 19 receives rotation from the machine spindle, and the cutter 20 reproduces the movement path of the probe 14 moving on the copier 15. Fixed on the movable table A horizontal boring machine part is fed to the cutter and machined. The proposed tool for turning non-circular profiles allows machining the outer and inner surfaces with both variable and constant radius and polygons. The transition from one surface shape to another is carried out by changing the copier and installing the tool holder, and for processing cylindrical surfaces the installation of the copier is not required. An apparatus for turning circular beams, comprising a housing, a slider with a tool holder, a copier and a probe, so that, in order to facilitate readjustment, it is equipped with a carrier sleeve placed in the housing with the possibility of rotation, on the latter a copier is attached, and the probe mounted on a slider, which is located in the carrier hub.
