FIG. 1 shows the cartridge.j longitudinal incision; in FIG. 2, a section L -; - in FIG. one; FIG. 3 is a section a-B in FIG. one .

The chuck includes a housing with a shank 1 and a tool holder 2 B. With which the collet tool 5 is clamped by means of a collet 3 and a nut 4

On the case and the holder is made; The flat face surfaces, which are each other to each other, have the same prism-shaped grooves 6 and 7 located parallel to each other on the body and the holder, the grooves are located under 90.

In-grooves, the iGariki 9 located in the separator 8 are installed. The holder 2 is tightened to the body by a nut 10 through the balls 11 installed between its inner end and the end of the holder 11, the nut 10 is locked by means of a lock nut 12. Radially 5; X holes x nuts 10 are fitted with adjustment screws 13 with lock nuts 14e for moving the holder 2 relative to the body in the radial direction and for

move radially in two mutually perpendicular directions by moving the slots 7 along the balls 9 and the balls 9 along the slots of the housing. The cartridge provides the ability to work as a rigidly fixed coaxial tail--. tonic instrument and floating instrument. For this purpose, the holder is either fixed with screws 13 in a position coaxially with the shank, turning the tool along the indicator, or removing screws 13 for a distance J at which the necessary tool float is provided. 3 il.

fixing the holder in position.

Installing the tool 5., fixed in the holder 2, in a coaxial position with the shank, is carried out using vies -1 with a 13 beat control on the indicator.

If it is necessary for the cartridge to operate in the tool's self-installation mode (for example, during deployment), the screws 13 are removed from the holder at a distance - :: {5th 5) which provides the necessary amount of self-alignment of the tool. Radial movements of the holder 2. from screws 13 or during the self-installation process, the VO mutually perpendicular directions in directions occur due to. moving the slots 7 of the holder along the balls 9 and the balls 9 along the slots b of the body. The balls are also designed to transfer the circle of sh. His puck from the body to the holder. 1110 during processing.
