Abstract
The invention relates to an eccentric mechanism, and in particular relates to an eccentric mechanism of a vertical type numerical control rotary pressing machine. The eccentric mechanism comprises an eccentric wheel sheathed on a main shaft hole, wherein an inner eccentric sleeve and an outer eccentric sleeve are sheathed on the outer wall of the eccentric wheel in sequence; the outer wall of the outer eccentric sleeve is provided with a positioning seat; and the diameter of the eccentric wheel can be changed. The eccentric mechanism enters the required position when in need of a workpiece, plays a role in supporting the workpiece so as to play a role in correcting and shaping at the forming stage, and returns to the original position after the work is finished, so that the operation is very convenient.
Description
Technical field
The present invention relates to a kind of eccentric stiffener, particularly relate to a kind of eccentric stiffener of vertical numerical control spinning machine.
Background technology
Cnc spinning machine is when the collapsible belt pulley of spinning multiple-grooved; The distortion of workpiece material between the spinning is in free state basically, is the specification requirement that guarantees flute profile, and workpiece inwall in addition support wheel (is also claimed eccentric wheel; Call eccentric wheel in the following text) so that shaping stage plays the effect of proofreading and correct shaping.
For needs that satisfy the loading and unloading part and the needs that some workpiece preform is also used interior support, eccentric wheel must enter into desired position (radially, angle) when workpiece needs, and work should be got back to and the main shaft position of coaxial (in claiming back) after accomplishing.This just proposes two problems to eccentric wheel: the one, can enter into the workpiece deformation district from the center when needed, and the 2nd, should be able on several directions, satisfy above-mentioned action.
Eccentric stiffener designs for satisfying above-mentioned job requirement.
Summary of the invention
For realizing above-mentioned purpose, the invention provides a kind of eccentric stiffener of vertical numerical control spinning machine, can enter into common part deformed area when needed from the center, and can satisfy above-mentioned action in three directions.
Technical scheme of the present invention is following:
A kind of eccentric stiffener of vertical numerical control spinning machine comprises the eccentric wheel that is enclosed within on the spindle hole, eccentric bushing and outer eccentric bushing in being with successively on the described eccentric wheel outer wall.
On the described outer eccentric bushing outer wall positioning seat is installed.
Described eccentric wheel is for changing the eccentric wheel of diameter.
Beneficial effect of the present invention is following:
The eccentric stiffener of vertical numerical control spinning machine of the present invention enters into desired position when workpiece needs, workpiece is played a supportive role, so that shaping stage plays the effect of proofreading and correct shaping, after work is accomplished, gets back to original position, and operation is very easy.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further.
Description of drawings
Fig. 1 is a position sketch map in the eccentric samsara;
Fig. 2 is the eccentric wheel first preform position view;
Fig. 3 is the eccentric wheel second preform position view;
Fig. 4 is an eccentric wheel shaping position sketch map;
Fig. 5 is the cutaway view of Fig. 2 along the A-A direction.
The specific embodiment
As shown in Figure 5, a kind of eccentric stiffener of vertical numerical control spinning machine comprises the eccentric wheel 1 that is enclosed within on the spindle hole (not identifying in the accompanying drawing of the present invention), and eccentric bushing 2 and outer eccentric bushing 3 are equipped with positioning seat 4 on outer eccentric bushing 3 outer walls in being with successively on eccentric wheel 1 outer wall.
Be illustrated in figure 1 as position in the eccentric wheel 1 go back to; Can load and unload part this moment; If (interior eccentric bushing 2 is motionless with respect to outer eccentric bushing 3 with outer eccentric bushing 3; Because the operating mechanism of cnc spinning machine all is fixed on outer eccentric bushing 3 end faces and can rotate with outer eccentric bushing 3) change counterclockwise 180
; Then again with interior eccentric bushing 2 change 180
; Then eccentric wheel 1 forwards the first preform position to, and is as shown in Figure 2; This moment as with outer eccentric bushing 3 change clockwise 90
(interior eccentric bushing 2 is with respect to outer eccentric bushing 3 invariant positions); Then eccentric wheel 1 just changes to the second preform position, and is as shown in Figure 3; As again with outer eccentric bushing 3 (interior eccentric bushing 2 is with respect to outer eccentric bushing 3 invariant positions) change clockwise 90
; Eccentric wheel 1 just changes to shaping position, and is as shown in Figure 4; As this moment with interior eccentric bushing 2 change 180
; Eccentric wheel 1 is again to going back to middle position, and is as shown in Figure 1.Certainly; When the first preform position and the second preform position; With interior eccentric bushing 2 rotate 180
, also can both make in the eccentric wheel 1 time.
Because after interior eccentric bushing 2 was confirmed with outer eccentric bushing 3 designs, minimum offset was exactly a definite value, during workpiece 5 vary in diameter, has only with the way that changes eccentric wheel 1 diameter and satisfies processing request.
The foregoing description only is used to the inventive concept of the present invention of explaining, but not to the qualification of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
Claims (3)
