Description

The lathe that is used for turning button

Technical field

The present invention relates to a kind of lathe that is used for turning button, and be specifically related to be used for the controllable device of mobile turning cutting tool.

Background technology

Known is used to remove swarf so that the technology that button is shaped is usually directed to custom-designed, the independently use of automatic machine tool.

The button blank that is generally circular plate type is maintained in the anchor clamps, and these anchor clamps can be assemblied on the swivelling tool-holder with four anchor clamps for example.

When the fixture support knife rest rotated, the button blank was presented to a series of work station, and one of them is exactly the turning station.

In turning process, the button blank is fixed.

In order to obtain different profiles, used cutting tool is shaped according to needed button profile.

The button blank is presented to the forming tool that is assemblied in around the chuck of the axis of symmetry of button blank rotation.Chuck advances in the axial direction, this cutter processing button blank, and this is shaped a side of button.

For fear of the special purpose that turning cutting tool is only had to be shaped the button that to have profile identical, that can not change, the lathe of some known type has the rotary chuck that is designed to be equipped with universal cutter, the position of this rotary chuck with respect to the axis of chuck be to use software program adjustable and be controlled, thereby mill out the profile of button as requested in a different manner.

The lathe of this known type is illustrated by for example utility application No.BS2005U000011.

The application of prior art demonstrates multiple important disadvantages.

At first, as described, a kind of device of known type of the button bracing or strutting arrangement with fixed position need use the turning cutting tool of solid shape, this means for each button-shape, needs specific blade.

Secondly, although allow to use the controlled general cutting tool that moves on both direction axially and radially when chuck rotates, the described device of above-mentioned utility model application has produced the extremely complicated mechanical realization of chuck.

At last, said apparatus does not allow to change the orientation of cutter in turning process, and this causes not reaching ideal results sometimes.

Summary of the invention

The purpose of this invention is to provide a kind of lathe that is used for turning button that utilizes simple and economic scheme to eliminate above-mentioned shortcoming.

This purpose is realized that by lathe of the present invention it has the feature described in the claim.

Put it briefly lathe rotary knob blank of the present invention rather than cutting tool.

Lathe of the present invention has cutter holder device, and this cutter holder device carries out controlled moving along at least two orthogonal axles, and comprises the device of the orientation that is used for the controlled change cutter.

Description of drawings

The specific embodiment

Accompanying drawing has shown lathe 1, and it comprises the knife rest that supports vertical axes or the basic part 2 of turntable 3, and this knife rest or turntable 3 have four radially and equidistant rotary chuck 4, and these chucks 4 designs are in order to support and rotary knob 5.

Chuck 4 (Fig. 4) is supported rotatably by the knife rest of turntable 3, and comprises the pulley 43 that utilizes transmission mechanism (Fig. 2) to drive by motor 44.

Chuck 4 comprises the anchor clamps 41 (Fig. 4) with conventional configurations, and it is held elastic closure around will be by the button blank 51 of turning.

More particularly, anchor clamps 41 comprise at least three elastic arms, and the lining 411 that these elastic arms are pushed in the closing position by spring 412 remains in the closing position.

For opening anchor clamps, outer sleeve acts on the lining and the effect of antagonistic spring and pushing it in the open position, and outer sleeve is moved by right angle control lever 413, and this right angle control lever 413 is at the effect lower swing of motor-driven cam 414.

Knife rest 3 (Fig. 1) is with equidistant steps will, for example one time one step rotation is with positioning chuck 4 with in the face of the corresponding button blank 51 of the platform 6 that supports turning cutting tool 7.

Turning cutting tool 7 can move along two orthogonal horizontal axis, and one of them axis is parallel to the axis of chuck 4, and turning cutting tool 7 also can wind the vertical axis rotation perpendicular to the axis of chuck 4.

Fig. 2 and Fig. 3 have shown basic part 2 that firmly is fixed to lathe 1 and the platform 6 of facing chuck 4.

Platform 6 has two first horizontal guide rails, 610, the first intermediate plates 61 and slides on this first horizontal guide rail 610.

Moving by electrical servo motor 611 of first intermediate plate 61 utilizes screw flight transmission mechanism 612 (Fig. 3) control.

First intermediate plate 61 comprises two second guide rails 614 perpendicular to first guide rail 612 again.

What slide on second guide rail 614 is second intermediate plate 62, screw flight transmission mechanism 622 controls that this second intermediate plate 62 is driven by electrical servo motor 621.

On second intermediate plate 62 is knife rest plate 63 (Fig. 3), and this knife rest plate 63 has the device 630 that is used to hinder turning cutting tool 7; Plate 663 is around near vertical axis 631 rotations of passing through the knife edge.

Plate 63 firmly is assembled to the first following idle pulley 633, this idle pulley 633 on plate 63, rotate and form cog belt around its running the axle.

With 634 be looped around second pulley 636 around, this second pulley 636 is supported on the vertical pins that vertically extend from second intermediate plate 62 (seeing Fig. 1 and Fig. 5) by the mode with idle running.

Pulley 636 is driven by servomotor 639, and the direct splined engagement of the axle of this servomotor 639 is to pulley.

Because being used for button blank 51 is positioned at the device of anchor clamps 41 is known types, therefore repeat no more.

Should be pointed out that and except above-mentioned turning station, the station of the boring/mark that is used for button of known type can be set also.

This machine operation is as follows.

In original position, knife rest is arranged to chuck 4 towards cutter 7, and cutter 7 preferably is set at the place, periphery of chuck.

On the chuck clamps near the uplink of turning cutting tool 7 button blank 51 is installed, motor 44 is activated and rotates this button blank.

Servomotor 611 and 621 is according to program behavior, so that stationary face is advanced along the path that is suitable for cutting desired profile on this button blank to the knife edge of the button blank of rotation.

The removal of material preferably is used for each rotation of chuck in single passage a small amount of amount of feeding carries out.

During travel path, cutter can change under the control of the same servomotor 639 of following same program with servomotor 611 and 621 with respect to the orientation of button blank.

In case finish turning, cutter just is back to original position, and turntable moves a step-length and moves to the following process station or discharge (not shown) with the button with processing before, and the button blank that will be installed on the chuck of upstream before is arranged to towards this cutter.

Device of the present invention has been realized all purposes of the present invention, mainly is to make it possible to come turning to have differently contoured button by the control program of revising servomotor simply, and need not changes the machine components of lathe.

Can and improve the modification embodiment and under the prerequisite of the scope of not abandoning claims, be applied to lathe.
