    Holders, which consist of a head part accommodating the tool and a holder body, are required for the automatic working of workpieces, in particular for the machining of workpieces, but also for industrial robots and the like. Head part and holding body are mutually held by clamping means, the bearing surfaces (5; 6) of which are provided with an interacting tooth system (11). The tooth system has several inclined surfaces (12) acting at an angle to one another, so that they are automatically centred. Head part (3) and holding body (4) are provided with a longitudinal bore (30), running essentially in the clamping direction, for accommodating an optical or optoelectronic measuring system. The measuring system enables both the tool wear and the quality of the machined surface to be continuously monitored. To this end, the reflected light of a radiation source is fed via sensors to a computer. <IMAGE>

    dexterous. When moving the pulling rod 8 from the power drive, the jaws, interacting with the tangled taper surfaces with the mating surfaces in the bore of the shank, draw closer together and cover the pull rod 12 of the head in contact with it on the taper surfaces. With further movement of the cam, the cams, in contact with the cylindrical surfaces of the bore, transfer the clamping force through the traction rod to the head and ensure its reliable fixation on the shank by means of
    one
    The invention relates to a machine tool industry and can be used on multioperational machines such as a machining center, etc.
    The purpose of the invention is to reduce the time for changing the tool due to the mechanized clamping of the head with the tool on the tool shank.
    Fig „1 shows a tool holder, a longitudinal section; in fig. 2 is a section A-A in FIG. 1; in fig. 3 shows an embodiment of a tool restoring device.
    The tool holder contains a shank 1 with an end gear teeth 2, a head 3 with a cutting element 4 and a counter end gear teeth 5. For clamping the head 3 on the shank with fixation - using a gear crowns 2 and 5 serves a mechanism, clamped in the form of a clamp the cartridge, the cams 6 of which are mounted in the bore 7, made in the shank coaxially to the gear crown 2,
    The cams 6 are connected by means of an annular protrusion 9 which is made on the belt 8 and an annular undercut 10 that is made in cams 10 and 8 is connected with a power drive (not shown) and is axially displaced in the opening 11, . the bore 7, which is full in the shank, is attached to the bore 7, a pull rod 12 is fixed coaxially to the gear 5 on the head 3. On the cams 6 there is a pair of cylindrical surfaces 13 and 14 and a pair of external conical surfaces 15 and 16, as well as
    torpovye gear crowns. At the end of the pull 8, there is a cylindrical protrusion 26 with a sealing element in the annular groove, which is placed with the possibility of axial movement in the opening 27 of the thrust rod. The axial openings 27.28 and 29 are made in the head, the pull rod. designed for the supply of a lubricant-cooling liquid or the passage of a light beam of an optical or electro-optical measuring system to the cutting element.
    the pair is internal; their conic surfaces 17 and 18, designed to interact with counter surfaces 19 and 20, 21 and 22, drilled in the bore, and surfaces 23 and 24, drilled on the pull rod. The outer cylindrical 13 and 14 and conical 15 and 16 surfaces on the cams and surfaces 19-22 are alternately arranged along the axis of the shank and at a distance from it, decreasing in the direction of thrust 8,
    The inner conical surfaces 17 and 18 on the cams and the surfaces 23 and 24 that respond to them are not spaced along the axis and are located at the same distance from it.
    In the axial direction, all the mentioned surfaces are located so that, with the engaged gears 2 and 5 and the loading of the force in the direction of arrow 25, the cylindrical surfaces 13 and 14 of the cams contact the mating surfaces 19 and 20 in the bore 7 and the inner conical surfaces 17 and 18 cams with mating surfaces 23 and 24 on the traction rod.

    At the end of the string 8, a cylindrical protrusion 26 is attached, which is adjacent to the possibility of axial movement with a hole 27 made in the pull rod. In the thread 8, the pull rod 3 and 12 in the head 3 are made coaxially with holes 27-29 intended for the passage of cooling or lubricant or light beam

    optical beam or electro-optical measuring system. Claims of the invention A toolholder containing a tailpiece with a torque gear vend, a head with a cutting element and a response gear torque gear and a head clamping mechanism on the tailpiece with a ficadium by means of the mentioned tooth-optic or electro-optical measuring System to the cutting member 4. In association with a protrusion 26 with a hole 27, a seal 30 is installed. The cams are spring-loaded in directions from the axis by a spring element 31. The clamping of the head 3 on the shank 1 with fixation by means of end gear rims is carried out the movement of the thrust 8 from the power drive in the open-ended Vendas, characterized by the direction of the arrow 25. At the same time, the cams due to the interaction of their outer conical surfaces 15 and 16 with the counter surfaces 21 and 22 in the bore move in the radial 15 direction to the axis and along In the process of contacting the cylindrical surfaces 13 and 14 of the cams with the counter surfaces 19 and 20 in the bore, 20 inner conical surfaces 17 and 18 of the cams begin to contact with the response surfaces 23 and 24 on the pull rod. Upon further pulling in of the rod 8, the head 3 is clamped with fixing by means of face gear Vendas 2 and 5. The operation of the cams 6 according to the two-arm lever during the clamping process makes it possible to reliably clamp the rod 30 12 on the conical surfaces 23 and 24 in spite of four-dimensional static certainty due to the presence of several simultaneously, that, in order to increase tool speed, the clamping mechanism is made into a chuck with a cam mounted in a coaxially formed shank with a toothed rim of a bore and connected with the possibility of radial movement and fixed axially with a thrust inserted into the holder and connected to a power drive, mounted with the possibility of axial movement in an aperture bore coaxially with the bore; a gear vendum with a brace rod; on the cams, there are predominantly two pairs of external surfaces and a pair of internal surfaces intended to interact with response surfaces; E, respectively, in the bore and m govom rod, the outer surfaces of the cams and their response surface in the bore are cylindrical and
