Abstract
The invention discloses a tap chuck which comprises a main handle, a maintaining body and a clamping body. The rear section of the clamping body is in threaded connection with the outer wall of the maintaining body, and the front sections of the maintaining body and the clamping body have circular conical surfaces in same conical degree. A plurality of equal aperture through holes are equally distributed on a same circumference at intervals in the front section of the maintaining body, close to an end head. Each through hole is internally provided with a steel ball, a locking screw is installed on a straight pipe wall of the clamping body, and a baffle is installed in the rear section of the clamping body. The baffle is fixed to the outside wall of the rear section of the clamping body through a fastener. A dialing sleeve which axially moves relative to the maintaining body is arranged in the front section of the clamping body. A spring is arranged on the wall of the clamping body at the tail end of the dialing sleeve, and a space is formed between the middle part of the dialing sleeve and the wall of the clamping body. The tap chuck provided by the invention has the advantages that the tap chuck is simple in structure, suitable for clamping different screw taps in various specifications, stable in clamping force, free from slippage or falling and high in safety.
Description
Technical field
The present invention relates to a kind of tap chuck, belong to machine tool accessories.
Background technology
Tap chuck commonly used during machine tool tapping has common drill chuck and collet, the cramping body front end of tap chuck is clamped the tap holder bar with the extruding form under the effect of holder, screw tap carries out tapping to workpiece under the drive of processing rotating shaft, in the tapping process, common drill chuck can't be adjusted the clamping force of screw tap, and screw tap can become flexible because of vibrations, therefore, screw tap occuring often skid at chuck, even comes off cause danger.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide the firm tap chuck of a kind of clamping.
The technical solution used in the present invention is:
A kind of tap chuck, comprise main handle, holder and cramping body, described cramping body back segment is connected with the holder outer wall thread, the leading portion of described holder and the leading portion of cramping body have the taper seat of identical tapering, the leading portion of described holder is near a plurality of equal aperture through holes that the five equilibrium interval is arranged on the same circumference of termination, a steel ball is housed in each through hole, on the straight section tube wall of described cramping body lock-screw is installed, the back segment of described cramping body is equipped with block, the back segment lateral wall of described block and cramping body is fixed by securing member, the leading portion of described cramping body is provided with the sliding set of doing axially-movable with respect to holder, the clamping body wall of described sliding set tail end is provided with spring, forms a space in the middle of the described sliding set with on the clamping body wall.
Described securing member is pin.
Pass through the rubber retaining ring sealing on described sliding set and the clamping body wall.
Beneficial effect of the present invention: tap chuck is simple in structure, adapts to the screw tap clamping of all size, and chucking power is stable, can not skid or come off, and is safe.
