Problems solved by technology

Because the drill chuck generally works under the condition of vibration and shock, due to inertia, the nut is easy to loosen, so that the jaws loosen the tool handle
Therefore, in operation, it is necessary to tighten the nut repeatedly, which hinders production

Abstract

The present invention discloses one kind of tapered wedge locked drill chuck, which includes a drill body, clamping jaws, a nut, an outer sleeve, a control sleeve, a pusher dog and a wedge locking ring. The wedge locking ring on the drill body drives the nut to rotate and has wedge block and elastic part pivoted inside it; the control sleeve is connected to the outer sleeve to rotate the wedge locking ring; and the pusher dog rotates synchronously with the control sleeve between the first location with uncoupled wedge block and the second location with contacted wedge block. The present invention may have rolling locking ring to replace the wedge locking ring to realize friction locking suitable for use under vibration condition.

Description

Bevel Locking Drill Chuck technical field The invention relates to a rotary tool clamping device, in particular to a wedge surface locking drill chuck. Background technique Conventional rotary tool clamping devices are used to clamp various rotary tools, such as drills, reamers, taps, etc. These rotary tools are also known as collets. A typical chuck, such as a drill chuck, includes a drill body, a plurality (eg, three) of jaws, a nut, a housing, etc., and some also include a back sleeve. Additionally, some chucks include bearing assemblies to reduce friction. A plurality of jaws are respectively installed in a plurality of oblique holes equally divided into each other in the drill body. The nut is arranged in the nut groove of the drill body, and cooperates with the thread of the jaw to form a thread transmission mechanism. The outer sleeve is set on the nut (in some cases, the nut is also sleeved with a nut sleeve). The outer cover has a key, and the nut has a key g...
