Abstract
The invention discloses an automatic centering clamping device for turning of annular workpieces. The automatic centering clamping device for turning of the annular workpieces comprises a stepped shaft, a driving nut, a guide disc and a disc-shaped expansion sleeve. The threaded end of the stepped shaft sequentially penetrates through the guide disc and the disc-shaped expansion sleeve and then is provided with the driving nut. At least two expansion grooves are evenly formed in the side wall of the open end of the disc-shaped expansion sleeve in the circumferential direction of the disc-shaped expansion sleeve. A taper angle matched with a guide boss is formed in the side wall of the open end of the disc-shaped expansion sleeve. The automatic centering clamping device for turning of the annular workpieces has the characteristics of being capable of achieving automatic centering, high in machining position precision, large in expansion force, stable and reliable in machining process, reasonable in design, simple in structure, convenient to operate, small in size, low in weight, convenient to disassemble and assemble, long in service life and convenient to use and popularize.

Technical field
The invention belongs to Machining Technology field, relate to a kind of Simple clamp, be specifically related to a kind of self-centering type clamping device for Drilling operation.
Background technology
The workpiece rotated mainly is carried out turnery processing with lathe tool by lathe process, one of machining mode that turnery processing is also the most frequently used. At present, in turnery processing, the main tool of self-centering clamping annular workpieces is scroll chuck, scroll chuck uses scope widely, when small lot annular workpieces is clamped, convenient and reliable, but run into high-volume annular workpieces need to add man-hour, adopt scroll chuck clamping annular workpieces exist dismounting part cost time, effort, substantially increase the labor intensity of labourer, reduce production efficiency and crudy can not be effectively ensured.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency of the prior art, it is provided that a kind of annular workpieces turnery processing self-alignment cramping arrangement, it can self-centering, Working position precision is high, swelling great efforts, and the course of processing is reliable and stable, reasonable in design, simple in construction, easy to operate, volume is little, lightweight, easy accessibility, long service life, it is simple to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of annular workpieces turnery processing self-alignment cramping arrangement, including playing fixed supporting role and one end outer circumference surface being provided with externally threaded multidiameter and the driving nut of the composition screw thread pair that matches with described multidiameter external screw thread, it is characterised in that: also include lower surface and be provided with the positioning disk of guide ledges and from inside to outside hold out against the dish type expansion set of annular workpieces to be processed; Described multidiameter has screw thread one end to be provided with described driving nut after sequentially passing through described positioning disk and described dish type expansion set, described dish type expansion set opening sidewall is evenly arranged with at least two expansion slot along its circumferencial direction, described dish type expansion set open end side pars intramuralis is provided with the conicity angles alpha matched with described guide ledges, and the span of described conicity angles alpha is 10 °-30 °.
Above-mentioned annular workpieces turnery processing self-alignment cramping arrangement, it is characterised in that: described guide ledges is cone.
Above-mentioned annular workpieces turnery processing self-alignment cramping arrangement, it is characterised in that: described guide ledges sidewall is provided with transition arc.
The present invention compared with prior art has the advantage that
(1) this annular workpieces turnery processing self-alignment cramping arrangement when clamping annular workpieces can self-centering, Working position precision is high.
(2) this annular workpieces turnery processing self-alignment cramping arrangement adopts dish type expansion set to extend out swelling annular workpieces to be processed, thus its swelling great efforts, the course of processing is reliable and stable.
(3) design of this annular workpieces turnery processing self-alignment cramping arrangement is very reasonable, simple and compact for structure, annular workpieces only need to be set in outside dish type expansion set by operator, tightens the clamp operation driving nut can realize annular workpieces, uses very easy.
(4) this annular workpieces turnery processing self-alignment cramping arrangement compact, lightweight, easy accessibility, it is simple to carrying and maintenance.
(5) this annular workpieces turnery processing self-alignment cramping arrangement is in use absent from rigid shock, thus its long service life, it is simple to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

Detailed description of the invention
A kind of annular workpieces turnery processing self-alignment cramping arrangement as Figure 1-Figure 4, including playing fixed supporting role and one end outer circumference surface being provided with externally threaded multidiameter 1 and the driving nut 5 of the composition screw thread pair that matches with described multidiameter 1 external screw thread, also include lower surface and be provided with the positioning disk 2 of guide ledges 2-1 and from inside to outside hold out against the dish type expansion set 4 of annular workpieces 3 to be processed; Described multidiameter 1 has screw thread one end to be provided with described driving nut 5 after sequentially passing through described positioning disk 2 and described dish type expansion set 4, described dish type expansion set 4 opening sidewall is evenly arranged with at least two expansion slot 4-1 along its circumferencial direction, the quantity of expansion slot 4-1 preferably four. Described dish type expansion set 4 open end side pars intramuralis is provided with and the described guide ledges 2-1 conicity angles alpha matched, and the span of described conicity angles alpha is 10 °-30 °, it is preferable that 20 °.
In the present embodiment, described guide ledges 2-1 is cone.
In the present embodiment, described guide ledges 2-1 sidewall is provided with transition arc, and transition arc can facilitate dish type expansion set 4 opening to slip into.
The work process of annular workpieces turnery processing self-alignment cramping arrangement of the present invention is: be first connected fixing to the multidiameter 1 of this annular workpieces turnery processing self-alignment cramping arrangement and lathe spindle, annular workpieces 3 is sleeved on outside dish type expansion set 4, spanner is used to turn driving nut 5 clockwise, drive nut 5 that dish type expansion set 4 can be driven to be moved to the left, the endoporus conical surface of dish type expansion set 4 and guide ledges 2-1 interact, dish type expansion set 4 can expand outwardly equably, thus the endoporus of swelling annular workpieces 3 to be processed. Annular workpieces 3 to be processed, after swelling, is started lathe and can be carried out turnery processing.
The above; it it is only presently preferred embodiments of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation above example made according to the technology of the present invention essence, all still fall within the protection domain of technical solution of the present invention.
