Description

The invention relates to mechanical engineering, mainly to devices for threading taps in mounted devices for plumbing. 5

A thread-cutting device is known, including a carbon pair, a screw nut and a drive shaft located in the housing with a cartridge for a tap Π X

The known device provides 10 threading 'cs copy one step.

A thread-cutting device is known, comprising a housing with a · placed in it, a spindle with a threaded ko and a pier and with a tool holder C2].

valuable spindle 2 in it, on which a replaceable threaded sleeve 3 is installed, which is at the same time the tool holder 4. On the housing 1, a rotary disk copier 7 with half nuts 8, each of which has a different thread pitch, is fixed with a nut 5 on the spline shaft 6. To fix this thread-cutting device in the two-coordinate device on the housing 1, holes 9 are provided.

The work of the proposed thread-cutting device is as follows.

When the nut 5 is detached, the disk copier 7 is removed from the splines of the shaft 6 and

However, this device provides threading in one step.

The purpose of the invention is expansion. technological capabilities by threading various steps.

This goal is achieved by the fact that in a thread-cutting device containing a housing with a spindle with a threaded copier and a holder for the tool, the threaded copier is made in the form of replaceable screw bushings mounted on the spindle with the possibility of axial movement, and a rotary disk made on it peripherals with half nuts with threads of various pitch for interaction with screw bushings.

In FIG. 1 shows the proposed thread-cutting device; figure 2 section aa in figure 1,

The proposed thread-cutting device comprises a housing 1 with a rotational rotation combine one of the half-nuts 8 with an opening in the housing 1 for a threaded replaceable sleeve 3 with the thread of the same step as on the half-nut 8. Then, the replaceable threaded sleeve 3 with a tap fixed therein is inserted into the opening of the housing 1 until connecting to spindle 2 and turning the spindle 2, screw the threaded replaceable sleeve 3 all the way, after which the thread-cutting device is fixed in a hinged two-coordinate device! lance (not shown), and moving along the guides of the device, install a tap along the necessary holes for threading by rotating the spindle (manually or mechanically).

The application of the proposed device can simplify the operation of cutting various pipes, while improving the quality of the thread and productivity.
