The technical scheme of the utility model is as follows:
the utility model provides a dysmorphism step axle class or dysmorphism bulb axle class part axle adds clamping apparatus, includes axis body, base, axis body and base are integrated into one piece, and axis body axle central point puts and has seted up the bulb clearing hole, the bottom of bulb clearing hole sets up spacing step, it dodges the clearing hole to be equipped with the dysmorphism on the axis body, the dysmorphism is dodged the clearing hole and is put through the hole with the bulb.
The limiting step is of an annular structure.
The shaft through hole formed by the annular limiting step has the advantage that the diameter of the shaft through hole can normally pass through the shaft.
The shaft through hole, the ball head through hole and the central line of the shaft body are the same axis.
The shape and the size of the special-shaped avoidance through hole are set according to different parts.
The ball head through hole is matched with the diameter of a part ball head or a step, the shaft body is matched with the diameter of a lathe chuck hole, and the thickness of the base is set according to the clearance between the lathe chuck and the soft claw.
The utility model has the beneficial effects that: this quick alignment anchor clamps of machining, reasonable in design, the practicality is strong. The mode that the three arcs are the same as the center line is adopted, the clamping accuracy of part clamping can be improved, and the effect of quickly aligning the axis is achieved. The special-shaped position is adopted for avoiding, the avoiding hole is designed according to the special-shaped part, the shape and the size of the special-shaped part of the part are not limited, the universality of the clamp is better embodied, and the problem of difficult clamping of the special-shaped part of the lathe is simply, conveniently and effectively solved. An annular limiting step is adopted for axial limiting; the ball head through hole is matched with the diameter of the step or the ball head part of the part, and the shaft through hole is matched with the size of the shaft part of the part to carry out radial constraint. The control of a plurality of degrees of freedom of parts is realized through a pair of anchor clamps, effectively guarantees clamping stability, has greatly reduced the influence of human factor to product quality, and product quality is stable, and efficiency is showing and is promoting, obviously reduces operating personnel's professional requirement.
