Abstract
The utility model provides a chuck, chuck includes disk body, parcel, the centre bore has in the disk body, parcel axial positioning, a serial communication port, the hole of parcel has the internal thread, chuck still includes the collet, the collet passes the centre bore, the collet rear portion have with the external screw thread of internal thread looks adaptation, the collet is used for holding workpiece. The utility model discloses can can produce pulling force backward to the work piece when pressing from both sides tight work piece, through the multi -direction fixed work piece of the application of force of going up, its firmness is more than traditional fixed mode.
Description
Technical field
The utility model relates to chuck.
Background technology
Tradition, chuck is often by the tooling device as fixation workpiece in machining, and be high-precision tooling device, it comprises disk body, parcel, bonnet.Wherein, workpiece is fixed by the mode that chuck is mostly clamped by horizontal direction.Chuck in use, because clamping force causes workpiece to drop not, can make process operation failure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of chuck, can clamping work pieces more strongly.For this reason, the utility model is by the following technical solutions:
A kind of chuck, described chuck comprises disk body, parcel, has centre bore in described disk body, described parcel axial location, it is characterized in that, the endoporus of described parcel has internal thread; Described chuck also comprises collet, and described collet is through centre bore, and described collet rear portion has the external screw thread suitable with described internal thread, and described collet is used for holding workpiece.
On the basis adopting technique scheme, the utility model also can adopt following further technical scheme:
Described chuck also comprises bonnet, described bonnet and disk body axial location parcel.
Bearing is provided with between described parcel and disk body.
Described bearing is that one between parcel front portion and disk body encloses steel ball.
Described collet front portion is elasticity handgrip.
Be provided with between disk body centre bore the conical surface coordinated, with adjustable elastic chuck openings of sizes outside the handgrip of described collet.
There is slot described collet front end and forms described elasticity handgrip, described collet and parcel be threaded by described collet and parcel and with disk body centre bore and with disk body inwall or coordinating of bearing form centralized positioning.
Owing to adopting the technical solution of the utility model, the utility model can produce pulling force backward to workpiece while clamping work pieces, and by multi-direction upper force fixation workpiece, its firmness is much larger than traditional fixed form.
Accompanying drawing explanation
Fig. 1 is the sectional view of chuck embodiment provided by the utility model.
Fig. 2 is the explosive view of chuck embodiment provided by the utility model.
Fig. 3 is the side view of chuck embodiment provided by the utility model.
Detailed description of the invention
With reference to accompanying drawing.A kind of chuck provided by the utility model, described chuck comprises disk body 1, parcel 2, bonnet 6, has centre bore 110 in described disk body, described bonnet and disk body axial location parcel.The endoporus of described parcel 2 has internal thread 21, and described chuck also comprises collet 3, and described collet 3 front portion is elasticity handgrip 33.
Described collet is through centre bore 110, and described collet 3 rear portion has the external screw thread 30 suitable with described internal thread, and described parcel 2 is threaded with described collet 3.
Bearing is provided with between described parcel 2 and disk body 1.Described bearing is that one between parcel front portion and disk body encloses steel ball 4.
Outside the handgrip of described collet 3 be provided with the conical surface 31,111 coordinated between disk body centre bore, with adjustable elastic chuck opening, clamping work pieces.There is slot 32 described collet 3 front end and forms described handgrip 33, described collet 3 and parcel 2 be threaded by described collet 3 and parcel 2 and with disk body centre bore 110 and with disk body inwall or coordinating of bearing form centralized positioning.
Drawing reference numeral 5 is the bevel gear coordinated with parcel 2, and 7 is the limited screw of bevel gear.Drive parcel 2 to rotate by bevel gear 5, make parcel 2 drive collet 3 to move and clamping workpiece or post-tensioning or forward while unclamping workpiece.
The foregoing is only specific embodiment of the utility model; but architectural feature of the present utility model is not limited thereto; any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among protection domain of the present utility model.
