Description

Eccentric drive shaft
Technical field
The present invention relates to the axial workpiece in machine, specifically a kind of eccentric drive shaft.
Background technique
General transmission shaft can only drive workpiece rotation, but eccentric shaft, not only can transmit rotation, can also revolution be transmitted simultaneously.Eccentric shaft is widely used in all kinds of machinery equipment.
Conventional eccentric shaft comprises axis body and is positioned at the eccentric spindle nose at axis body two ends.This eccentric shaft is generally integrative-structure, when axle end wear, can only replace whole eccentric shaft, thus cause great waste, add the user cost of eccentric shaft.
Summary of the invention
The present invention is directed to the problems referred to above, provide during a kind of axle end wear and do not need integral replacing, the eccentric drive shaft of user cost can be reduced.
According to technological scheme of the present invention: a kind of eccentric drive shaft, comprise axis body and be positioned at the first spindle nose and second spindle nose at described axis body two ends, the axis coaxle of described first spindle nose and described second spindle nose and be parallel to the axis of described axis body, described first spindle nose and be Split type structure between described second spindle nose and described axis body, described first spindle nose and described second spindle nose are fixed on described axis body respectively by fastening piece.
Described first spindle nose and described second spindle nose are separately fixed on the first holder and the second holder, described first holder and described second holder have the journal hole with described first spindle nose and described second spindle nose axis being parallel, the hole wall of described journal hole is provided with axial fixture block and axially grooved, the both sides of described fluting have coaxial through hole and tapped hole; The two ends of described axis body are respectively arranged with the axle journal matched with described journal hole, described axle journal are provided with the draw-in groove matched with described axial fixture block.
Described first spindle nose and described second spindle nose are welded on described first holder and described second holder respectively.
Described first spindle nose and described second shaft head structure measure-alike, described first holder and described second holder symmetry make.
Described axis body has keyway.
Technique effect of the present invention is: the present invention is Split type structure, formed by the first spindle nose, the second spindle nose and axis body three sections fit, when the first spindle nose or the second spindle nose need again to change due to serious wear, only need to unload from axle, and do not need to change whole eccentric drive shaft, thus provide cost savings.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ Fig. 6, comprise the first spindle nose 1, first holder 2, axis body 3, second holder 4, second spindle nose 5, axle journal 6, draw-in groove 7, through hole 8, fluting 9, tapped hole 10, fixture block 11, journal hole 12, keyway 13 etc.
As shown in Figure 1, the present invention is a kind of eccentric drive shaft, comprise axis body 3 and be positioned at first spindle nose 1 and second spindle nose 5 at axis body 3 two ends, the axis coaxle of the first spindle nose 1 and the second spindle nose 5 and be parallel to the axis of axis body 3, first spindle nose 1 and be Split type structure between the second spindle nose 5 and axis body 3, the first spindle nose 1 and the second spindle nose 5 are fixed on axis body 3 respectively by fastening piece.
First spindle nose 1 and the second spindle nose 5 are weldingly fixed on the first holder 2 and the second holder 4 respectively, and the first spindle nose 1 is identical with the second spindle nose 5 physical dimension, and the first holder 2 and the second holder 4 symmetry make.As shown in Figure 5, Figure 6, first holder 2 and the second holder 4 have the journal hole 12 with the first spindle nose 1 and the second spindle nose 5 axis being parallel, the hole wall of journal hole 12 is provided with axial fixture block 11 with axially grooved 9, the both sides of fluting 9 have coaxial through hole 8 and tapped hole 10.
As shown in Figure 2 to 4, the two ends of axis body 3 are respectively arranged with the axle journal 6 matched with journal hole 12, axle journal 6 are provided with the draw-in groove 7 matched with axial fixture block 11.Axis body 3 also has keyway 13, is connected with other driving components by key.
When the present invention makes, the first spindle nose 1 and the first holder 2 integrally welded, the second spindle nose 5 and the second holder 4 integrally welded, whole component is formed by the first spindle nose 1, second spindle nose 5 and axis body 3 three sections fit.During assembling, first spindle nose 1 and the second spindle nose 5 are respectively charged into the two ends of axis body 3, and to be matched with draw-in groove 7 by fixture block 11 and locate, then inserting bolt in the through hole 8 of the fluting 9 of the first holder 2 and the second holder 4, and bolt is screwed in tapped hole 10, the first spindle nose 1 and the second spindle nose 5 are fixed on axis body 3.
When the first spindle nose 1 or the second spindle nose 5 need again to change due to serious wear, only need to unclamp bolt and unload from axle, and do not need to change whole eccentric drive shaft, thus provide cost savings.
Structure of the present invention is simple, makes, easy for installation.
