Abstract

1,073,681. Machine tool details. HORDELL ENGINEERING Ltd. Feb. 12, 1965 [Nov. 12, 1963], No. 44571/63. Headings B3B and B3C. A tool magazine turret for attaching to a drill 40, Fig. 1, comprises a shaft 7 screwed into the motor spindle, a pillar 11 screwed into the motor casing or secured thereto by a clamp 4, an indexable casing 6 having a hardened steel sleeve 18, which is a sliding fit on pillar 11, and spring-urged collets 12, 16 into which are secured drills, reamers, spanners &c. A spring- urged plunger 10 has balls 30 placed in an annular groove 42, and a second pair of spring- urged balls 25 is carried by pillar 11. In operation, the casing 6 is indexed around pillar 11, to align the required tool with spindle 7. The magazine is pushed towards the drilling machine, to thus engage end 9 of the collet with a slot in the end of spindle 7. Balls 25 are forced inwardly by a bevel portion 44 on sleeve 18, and balls 30 enter a groove 45 in the sleeve, to thus lock the collets axially. The collets can be tightened without removing them from the turret, by using spanners on the end (48) of the collet nut, and on a flat 49 on spindle 7. A dust shield 31 is provided.
