Abstract
The invention discloses a bent axle machining clamp. The clamp comprises a clamp body, wherein a center sleeve is fixedly arranged at one end face of the clamp body, an elastic expansion sleeve is arranged in the clamp body, and an opening end of the elastic expansion sleeve is an outward inclined horn mouth; a wedge-shaped ring is arranged in the opening end of the elastic expansion sleeve, and the wedge-shaped ring and the elastic expansion sleeve are connected through a fastening screw. The clamp provided by the invention is simple in structure and low in manufacture cost; furthermore, the bent axle can be positioned by the expansion connection, so that the bent axle is simple to clamp, dismount and adjust; in addition, the clamp can be suitable for the machining of different specifications of bent axles by means of the change of clamp bodies provided with different eccentric distances, so that the bent axle machining clamp is good in universality.
Description
Technical field
The present invention relates to technical field of tooling clamps, particularly a kind of fixing clamping device being positioned at the crank processing of eccentric position on bent axle.
Background technology
Bent axle due to its structural plane more, and crank on bent axle and bent axle are not on the same axis, and when adopting traditional clamping with three-jaw chuck, clamping process is cumbersome, and is not easy centering, easily produces error.There is a kind of special eccentric chuck fixture at present, eccentric stiffener is provided with in this eccentric chuck fixture, add man-hour, by eccentric chuck fixture clamping on lathe spindle, then by bent axle clamping on eccentric chuck, the crank that can realize bent axle being in eccentric position is processed, but this eccentric chuck fixture, complicated structure, and cost is more expensive.
Summary of the invention
Technical problem to be solved by this invention there is provided that a kind of structure is simple, cost is low, and Set and Positioning precision is high, clamping, dismounting or Crankshaft Machining fixture easy to adjust.
For solving the problems of the technologies described above, present invention employs a kind of Crankshaft Machining fixture, comprise clamp body, described clamp body end face is installed with center sleeve, elastic expansion sleeve is provided with in described clamp body, the openend of described elastic expansion sleeve is outward-dipping horn mouth, is provided with cambridge ring in the openend of described elastic expansion sleeve, and inclined-plane and the inclined-plane of elastic expansion sleeve openend of the described cambridge ring described cambridge ring that matches is connected by holding screw with between elastic expansion sleeve.
As a further improvement on the present invention, between described center sleeve and clamp body be interference fit.
Structure of the present invention is simple, manufacturing cost is little, is positioned bent axle by expansion-joints, and the clamping of bent axle, dismounting and adjustment are simple; And only need change the processing that namely clamp body with different eccentric throw is applicable to different size bent axle, there is good versatility.
Accompanying drawing explanation
Fig. 1 is the structural representation of duty of the present invention.
Fig. 2 is I place's partial schematic diagram in Fig. 1.
In figure, 1, lathe chuck; 2, top; 3, clamp body; 4, center sleeve; 5, elastic expansion sleeve; 6, cambridge ring; 7, holding screw; 8, bent axle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1 and 2, a kind of Crankshaft Machining fixture, comprise clamp body 3, clamp body 3 end face is installed with center sleeve 4, be provided with elastic expansion sleeve 5 in clamp body 3, the openend of elastic expansion sleeve 5 is outward-dipping horn mouth, is provided with cambridge ring 6 in the openend of elastic expansion sleeve 5, the inclined-plane of cambridge ring 6 matches with the inclined-plane of elastic expansion sleeve 5 openend, is connected between cambridge ring 6 with elastic expansion sleeve 5 by holding screw 7.
In the present invention, be interference fit between center sleeve 4 and clamp body 3.
Add man-hour, elastic expansion sleeve 5 is enclosed within the central shaft of bent axle 8, clamp body 3 is enclosed within elastic expansion sleeve 5, withstand in the center sleeve 4 of clamp body 3 by top 2 of top 2 on lathe chuck 1 and tail stock, tighten holding screw 7, under the effect of holding screw 7 axial force, elastic expansion sleeve 5 struts by cambridge ring 6, bent axle 8 is fixed on clamp body 3, now can starts to be in the processing of the crank on same axis to center sleeve 4.
