Abstract
The invention discloses a turning fixture for no-stop workpiece clamping. The turning fixture comprises a flange plate and a fixture body; the fixture body is fixed on a machine head box of a machine tool by a bolt through the flange plate; the fixture body includes an inner taper sleeve, a spring chuck arranged on the inner taper sleeve, a thread retainer ring, a roller bearing and a thrust sleeve; the roller bearing is connected between the thrust sleeve and the inner taper sleeve; the thread retainer ring coats the inner taper sleeve, and is fixedly connected with the thrust sleeve; the spring chuck is connected to a lathe main shaft; and the thrust sleeve is arranged for a handle. The turning fixture for no-stop workpiece clamping uses the spring chuck for clamping workpieces, realizes the workpiece clamping by a lathe under the condition of no stop, performs the turning, is convenient for workpiece clamping, is high in clamping positioning precision, is stable and reliable in work, and effectively improves the working efficiency.
Description
Technical field
The invention belongs to the technical field of the loading of workpiece or gripping mechanism, be specifically related to a kind of lathe clamp for clamping workpiece by no shutting down.
Background technology
At present, on lathe when the batch cylindrical of the little sleeve workpiece of turning or end face, workpiece is usually and is clamped in scroll chuck, after being completely processed, first to stop and to be replaced workpiece again, clamping workpiece so frequently, start lathe continuously, this want operator put into substantial amounts of man-hour and muscle power for stopping, clamping workpiece, driving etc. back work, both lost time, expended again muscle power, the abrasion of lathe equipments is also bigger, greatly have impact on work efficiency, also reduce the service life of lathe simultaneously.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of lathe clamp for clamping workpiece by no shutting down, this lathe clamp for clamping workpiece by no shutting down, utilize collet to clamp workpiece, it is achieved lathe is clamping workpiece when not parking, carry out turnery processing, clamping workpiece is convenient, Set and Positioning precision is high, stable and reliable in work, is effectively increased work efficiency.
In order to achieve the above object, one lathe clamp for clamping workpiece by no shutting down of the present invention, including ring flange and clamp body, clamp body is fixed by bolts on machine tool head box body by ring flange, collet, threaded collar, roller bearing and the thrust housing that clamp body includes inner conical drogue, is arranged on inner conical drogue, described roller bearing is connected between thrust housing and inner conical drogue, described threaded collar is sleeved on inner conical drogue and fixes with thrust housing and is connected, described collet is connected on lathe spindle, and described thrust housing is provided with for handle.
Further, described threaded collar and inner conical drogue tip-clearance are set to 0.1～0.2mm.
Further, described roller bearing is set to single-row tapered roller bearing.
Further, described thrust housing is threaded on ring flange.
Further, described collet one end is provided with the Morse taper shank being connected with lathe spindle taper hole.
The beneficial effects of the present invention is:
Lathe clamp for clamping workpiece by no shutting down 1 of the present invention, achieve lathe in not parking situation, change clamping workpiece, be effectively increased work efficiency；2, Set and Positioning precision is high, and piece-holder is firm, and turning is reliable and stable；3, compact conformation, it is simple to installing and regulate clamping dynamics, clamping workpiece is convenient and swift；4, decrease the Fraquent start to lathe, reduce the degree of wear of equipment, extend the service life of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of lathe clamp for clamping workpiece by no shutting down of the present invention.
Accompanying drawing labelling: 1-ring flange；2-thrust housing；3-threaded collar；4-inner conical drogue；5-collet；6-handle；7-main shaft；8-headstock housing；9-Morse taper shank.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
It is illustrated in figure 1 the structural representation of lathe clamp for clamping workpiece by no shutting down of the present invention；One lathe clamp for clamping workpiece by no shutting down of the present invention, including ring flange 1 and clamp body, clamp body is fixed by bolts on machine tool head box body 8 by ring flange 1, collet 5, threaded collar 6, roller bearing and the thrust housing 2 that clamp body includes inner conical drogue 4, is arranged on inner conical drogue 4, described roller bearing is connected between thrust housing 2 and inner conical drogue 4, described threaded collar 3 is sleeved on inner conical drogue 4 and fixes with thrust housing 2 and is connected, described collet is connected on lathe spindle 7, and described thrust housing 2 is provided with for handle 6.
During the present embodiment work, collet 5, inner conical drogue 4 and lathe spindle 7 rotate simultaneously, and shell 1, threaded collar 3, thrust housing 2 is then fixing not to be rotated, the clamping of workpiece is to drive roller bearing to move to spindle end by mobile thrust housing 2, thus promoting inner conical drogue 4 to realize, when unloading workpiece, if reversely mobile thrust housing 2, make threaded collar 3 do to move axially away from spindle end, thus promoting inner conical drogue 4, pull-off spring chuck, this structure utilizes collet to clamp workpiece, realize lathe clamping workpiece when not parking, carry out turnery processing, clamping workpiece is convenient, Set and Positioning precision is high, stable and reliable in work, it is effectively increased work efficiency.
Further, it is preferred that described threaded collar 3 is set to 0.1～0.2mm with inner conical drogue 4 tip-clearance, and this structure avoids collet 2 to deform more than elastic limit.
Further, it is preferred that described roller bearing is set to single-row tapered roller bearing, this structure is conducive to improving the service life of roller bearing.
Further, it is preferred that described thrust housing 2 is threaded on ring flange 1, this structure is conducive to rotating thrust housing 2 by handle 6, easy to operate, laborsaving.
Further, it is preferred that described collet 5 one end is provided with the Morse taper shank 9 being connected with lathe spindle 7 taper hole, and this structure will be easy to be arranged on lathe by collet 5, convenient dismounting.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
