SU1228973A1 - Floating cutter head - Google Patents

Description

2. The head according to claim 1, about tl and ch and y with that, in order to expand; Neither the technological capabilities by working with a rigidly fixed tool, it is equipped with an installed. The invention relates to metalworking and can be used when turning threaded surfaces on multi-spindle turning semi-automatic machines.

The aim of the invention is to reduce the time for changing the tool by providing a change of holder and setting it out of the machine, as well as expanding the technological possibilities by operating with a fixed tool.

FIG. Figure 1 shows the floating cutting head, continuing the incision; in fig. 2 - the same, top view; in fig. 3, section A-A in FIG. one; 4 - section BB on 4ig. one; FIG. 5 is a section along the line B-B in FIG. one.

The floating cutting head includes a housing 1 with a shank 2 intended for mounting and clamping in a rack on a longitudinal caliper of a multi-spindle semi-automatic device. With the housing 1 by means of cylindrical guides 3 and 4 arranged perpendicular to the axis of the housing 1, the holder 5 is connected with the cutters 6, secured by means of crackers 7 and screws 8. The radial height of the cutters 6 is adjusted by screws 9.

The guide 3 is installed in the openings of the housing 1 with the possibility of its extraction and axial fixation with the screw to, the entrance of the PSM into the annular conical groove after the holder 5 and the housing 1 have been installed in the opening.

in the axial hole, which is set apart in the housing, by means of an adjusting screw with a tapering end, designed to accommodate the taper hole, which is mounted in the holder along the axis of the housing.

At the ends of the guide 4, there is made up # 1 of the face 11, and it is installed in the housing 1 by interfacing these holes with the grooves 12, which are open on its outer side, whose walls are parallel to the plane in which the guides 3 and 4 are located. the axial bore of the housing 1 is installed adjusting

a screw 13 with a conical end designed to be in contact with a co-hole, made in the holder 5 along the axis of the housing.

B: machining process holder 5

moves along guides 3 and 4, ensuring the self-installation of the cutters 6 on the surface to be treated.

The movement of the holder is limited by the screw cone 13.

If necessary, work cutters, rigidly fixed relative to the body, the screw 13 is wrapped until full contact of its conical end

with a holder hole 5. To remove the holder 5 in order to adjust the cutters to the machining size outside the machine, guide 3 will be unscrewed, unscrew the screw 10, and removed from the holes of the housing 1 and the holder 5. Next, move the holder 5 from the guide 4 in the slots 12 until it is disconnected from housing 1. Installation of the holder 5 into housing 1 is carried out in the opposite direction.

order The flats 11 simultaneously fix the guide 4 against falling out of the holes of the holder 5.

Claims (2)

1. A FLOATING CUTTER HEAD, in the body of which, by means of cylindrical guides located in a plane perpendicular to its axis, a tool holder is placed, characterized in that, in order to reduce tool change time by changing the holder and adjusting it outside the machine, one of guides installed in holes made in the housing with the possibility of fixation and removal, and on the outside of the housing open grooves are made, the walls of which are parallel to the plane of arrangement of the guides and cheny to interact with the guide provided on the other flats. 2. Head on π. 1, distinguishing myself with me in that, in order to expand-; To obtain technological capabilities by working with a rigidly fixed tool, it is equipped with an adjusting screw with a conical end installed in an axial hole made in the housing and designed to be placed in a conical hole made with a holder along the housing axis.
