Embodiment Construction

[0091] The collet of the present invention can be used to clamp handle-type tools that produce the main function by rotary motion, such as drill bits, taps, reamers, etc., for the convenience of description, they are collectively referred to as tool handles in this specification. The present invention will be further described below in conjunction with the accompanying drawings.

[0092] In the description, relative to the chuck itself, the direction where the tool handle is located is "front", and the direction where the drive shaft of the power source is located is "rear". When describing in conjunction with the accompanying drawings, "front" is generally also referred to as "bottom", and "rear" is generally also referred to as "rear". Except for otherwise special instructions or circumstances that obviously cannot be understood according to the instructions.

[0093] figure 1 is an exploded view of a collet with reverse stop according to a first embodiment of the inventi...

Abstract

The clamping head having reverse stopping device comprises a clamping head whose back end connects to the driving shaft of power source and which has several diagonal holes which are equality parted along the circumference direction; several clamping-claws which has the screw thread on its outside surface and are installed respectively in corresponding diagonal hole. Nut with screw thread on inner surface is installed on the clamping body which can join with the clamping-claw thread. The out-bushing is installed on the clamping body and is jointed with driving nut; the reverse stopping device is fixed on the clamping device which rotates synchronousely with the out-bushing has a elastic stopping claw at least. The elastic stopping claw can prevent the friction and block between the clamping and the nut.

Description

technical field [0001] The invention relates to a rotary tool clamping device, in particular to a collet with a reverse stop device, which prevents the jaw from continuing to rotate relative to the nut, and prevents the plane of the end of the thread of the jaw from coming into contact with the nut. Excessive extrusion of the inner ring cut-off plane of the thread produces excessive friction and seizure. Background technique [0002] 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 body, a plurality (eg, three) of jaws, a nut, a housing, etc., and sometimes a back sleeve. Additionally, some chucks include bearings and bearing pads to reduce friction. The outer sleeve and the bearing pad are tightly matched with the clip body respectively. The three clamping jaws are respectively installed in three oblique ho...
