1,230,213. Chucks; cutter arbors. E. JAHRL. 13 Sept., 1968 [15 Sept., 1967], No. 43711/68. Headings B3B and B3K. A chuck for gripping a tool holder 9 comprises at least two sets of balls 11 and 12 held in engagement with recesses or grooves in the holder 9 by a spring-biased outer sleeve 3, the set of balls 12 engaging rigidly in recesses to lock the holder against relative rotation whilst the set of balls 11 act on the slope of a groove 14, or equivalent recesses, to resiliently urge the holder 9 into the chuck. For additional locking the holder may be provided with screw-threads to screw into the end of the outer sleeve 3 (Figs. 2 and 3, not shown). A locking device may be provided to lock the sleeve 3 in its locked position and comprises a nut and ball-race co-operating with a groove in the chuck body (Figs. 7-9, not shown).

专利说明:

The invention relates to metal working, namely to devices for fastening end tools. A quick-change cartridge is known, comprising a body, a holder mounted therein and a sleeve enclosing it, contacting with the holder by means of two axially displaced rows of balls, wherein the balls of one row differ in diameter from the balls of the other row and the balls of one the rows are located in the annular groove made on the holder and the other in the holes 1 made on the holder. This cartridge is closest to the invention according to the technical essence and the achieved result. The disadvantage of the known cartridge is the unreliable clamping of the tool, since it is carried out only by balls of one row. The purpose of the invention is to improve the reliability of the tool clamp. For this, in the proposed cartridge, the sleeve is spring-loaded, and on its inner surface there is an annular protrusion and a conical section, the surface of the latter contacting the balls located in the annular groove, and the surface of the protrusion contacting the balls located in the wells. The drawing shows the described cartridge. The cartridge includes a housing 1, a holder 2 mounted therein and a sleeve 3 enclosing it, which contacts the holder 2 by means of a series of balls 4 and 5 displaced in the axial direction. The balls 4 of one row differ in diameter from the balls 5 of the other row. The balls 4 are located in the annular groove 6 made on the holder 2, and the balls 5 of the other row are made in the holes 7 made on the holder. The sleeve 3 is spring-loaded 8, and on its internal surface 9 there is an annular projection 10 and a conical 11 section, the surface of which contacts the balls 4. The surface of the protrusion 10 is in contact with the balls 5. In the holder 2 fixed end tool 12. The body has a tapered shank 13 for fixing in the spindle of the machine. The holder 2 is made with a tapered shank 14 mounted in the conical bore of the housing. By
