Abstract
The invention relates to an expansion sleeve lathing clamp. The expansion sleeve lathing clamp comprises a flange, an inner core expansion sleeve, an eccentric shaft and a cone top mandrel, wherein the inner core expansion sleeve is fixed to the flange through screws, an axial cavity used for containing the cone top mandrel is formed in the inner core expansion sleeve, an open through hole is formed in one end of the inner core expansion sleeve, the front end of the cone top mandrel extends out of the through hole, a radial through hole used for containing the eccentric shaft is formed in the inner cone expansion sleeve, the eccentric shaft makes contact with the cone top mandrel, and a spring is arranged between the cone top mandrel and the inner core expansion sleeve. The expansion sleeve lathing clamp has the advantages of being convenient to install and detach, capable of lowering the machining difficulty and improving the machining efficiency and accuracy and the like.
Description
Technical field
The present invention relates to mechanical clamp technical field, particularly expansion set vehicle clamper.
Background technology
In machining, some workpiece are positioned by its endoporus and are clamped, and existing fixture or complicated structure, be exactly unload cumbersome, and scarcely can ensure very high axiality, often can not satisfy condition requirement, causes machining accuracy poor.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of easy to loading and unloading, reduce difficulty of processing, improve the expansion set vehicle clamper of working (machining) efficiency and machining accuracy.
Realize technical scheme of the present invention as follows:
Expansion set vehicle clamper, comprise ring flange, inner cone expansion set, eccentric shaft and vertex of a cone axle, inner cone expansion set is fixed by screws on ring flange, the axial cavity of accommodating vertex of a cone axle is established in inner cone expansion set, one end of inner cone expansion set be provided with open hole, vertex of a cone axle front end is stretched out from through hole, inner cone expansion set is also provided with the radial direction through hole of accommodating eccentric shaft, eccentric shaft and vertex of a cone mandrel contacts, be also provided with spring between vertex of a cone axle and inner cone expansion set.
Described eccentric shaft is fixed on inner cone expansion set by axle sleeve, and advantage is convenient to axle sleeve rotation move up and down, and also plays the effect of fixed eccentric shaft simultaneously.
Described vertex of a cone axle front end is stretched out throughhole portions and is provided with screw thread, and advantage can support the use nut vertex of a cone axle to be fixed, and is convenient for changing eccentric shaft or other parts like this and does not affect the use of vertex of a cone axle.
Described inner cone expansion set is provided with multiple radial slot along its axis direction, and advantage is the distending being convenient to inner cone expansion set, workpiece pressing.
Have employed above-mentioned scheme, axial cavity and radial hole are set to communicate, and vertex of a cone axle contacts with eccentric shaft again, so just can control the movable of vertex of a cone axle by the rotation of eccentric shaft soon, thus reach the object of clamping work pieces; The open hole that inner cone expansion set is provided with is on the one hand in order to vertex of a cone axle can be made to have living space displacement, on the other hand can also with the use of nut; The spring be connected between vertex of a cone axle with inner cone expansion set can make vertex of a cone axle automatically reset; In use, the present invention not only structure is simple, Workpiece fixing can be made to feel relieved, ensure that the axiality of workpiece, and also ensure that machining accuracy and the efficiency of workpiece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right view of inner cone expansion set in Fig. 1;
In accompanying drawing, 1 is ring flange, and 2 is inner cone expansion set, and 3 is eccentric shaft, and 4 is vertex of a cone axle, and 5 is open hole, and 6 is spring, and 7 is axle sleeve, and 8 is screw, and 9 is groove.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, expansion set vehicle clamper, comprises ring flange 1, inner cone expansion set 2, eccentric shaft 3 and vertex of a cone axle 4, inner cone expansion set 2 is fixed on ring flange 1 by screw 8, establishes the axial cavity of accommodating vertex of a cone axle 4 in inner cone expansion set 2, one end of inner cone expansion set 2 be provided with open hole 5, vertex of a cone axle front end is stretched out from open hole 5, inner cone expansion set 2 is also provided with the radial direction through hole of accommodating eccentric shaft 3, eccentric shaft 3 contacts with vertex of a cone axle 4, is also provided with spring 6 between vertex of a cone axle 4 and inner cone expansion set 2.
Described eccentric shaft 3 is fixed on inner cone expansion set 2 by axle sleeve 7, and advantage is convenient to eccentric shaft rotation move up and down, and also plays the effect of fixed eccentric shaft simultaneously.
Described vertex of a cone axle 4 front end is stretched out throughhole portions and is provided with screw thread, and advantage can support the use nut vertex of a cone axle to be fixed, and is convenient for changing eccentric shaft or other parts like this and does not affect the use of vertex of a cone axle.
Described inner cone expansion set 2 is provided with multiple radial slot 9 along its axis direction, and advantage is the distending being convenient to inner cone expansion set 2, workpiece pressing.
Before turning, use spanner rotation eccentric axis, vertex of a cone axle is spread out left by the elastic force of spring by vertex of a cone axle, now inner cone expansion set shrinks, and workpiece can be loaded onto, then rotate backward eccentric shaft, vertex of a cone axle is moved right, now inner cone expansion set swelling workpiece, so just can turning.
