The utility model relates to a kind of wedge-type centering and clamping mechanism, along hollow shaft center line, be arranged with two same apparatus, each device is that wedge axle is flexibly connected with hollow shaft, in the wedge axis hole of wedge axle, be connected with center sleeve, hollow shaft is flexibly connected with pivoting support, and pivoting support is provided with spring push-rod, and the axial line of spring push-rod is vertical with the axial line of hollow shaft, the cylindrical of spring push-rod circular arc end face and wedge axle is tangent, and the other end is fixedly connected with locating piece.This device can significantly shorten the parts fixation time, and Reducing distortion amount improves part processing precision.

Description

A kind of wedge-type centering and clamping mechanism
Technical field
The utility model relates to a kind of centering and clamping mechanism, is particularly useful for the workplace that numerically controlled lathe and engine lathe turning large thin-wall element need to be felt relieved and be clamped.
Background technology
At present, the outer bowlder of numerically controlled lathe and engine lathe turning rotary part still clamps by three-jaw or the centering of four paws chuck endoporus, this method clamping time is long, be not easy centering, especially thin-walled parts adopts three-jaw or the centering of four paws chuck endoporus to clamp more easily distortion, needs the folder of trial assembly repeatedly, when producing in enormous quantities, trial assembly folder not only affects centering precision repeatedly, also affects production efficiency.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of wedge-type centering and clamping mechanism, be specially adapted to the centering clamping to thin-wall part on lathe, by wedge-type adjective-centre structure and a plurality of push rod locating piece, realized and reduced part deformation amount, clamping centering once completes, reduce the clamping time, enhance productivity.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of wedge-type centering and clamping mechanism, along hollow shaft center line, be arranged with two same apparatus, each device is that wedge axle is flexibly connected with hollow shaft, in the wedge axis hole of wedge axle, be connected with center sleeve, hollow shaft is flexibly connected with pivoting support, pivoting support is provided with spring push-rod, the axial line of spring push-rod is vertical with the axial line of hollow shaft, the cylindrical of spring push-rod circular arc end face and wedge axle is tangent, and the other end is fixedly connected with locating piece.
Described hollow shaft and wedge axle active connection place are provided with long kidney-shaped hole, between hollow shaft and wedge axle, by straight pin, are connected, and the position of long kidney-shaped hole is corresponding with straight pin position.
The beneficial effects of the utility model are: adopt wedge-type adjective-centre structure, and on pivoting support, be provided with the push rod tangent with wedge axle, not only increased the rigidity of wedge-type centering and clamping mechanism, and reduce the deflection of part, clamping centering once completes, reduce the clamping time, enhance productivity, safe and reliable.
In hollow shaft, be provided with long kidney-shaped hole, straight pin and wedge axle can be moved left and right at long kidney-shaped hole place, part easy to setup.
Adopt spring push-rod, push rod movable upper end connects locating piece, by promoting wedge axle, to spring push-rod, apply certain thrust, push rod passes to locating piece by power and clamps part, by the adjustment up and down of locating piece, both can process equal diameter part and also can process anisodiametric part, easy to operate, guarantee positioning precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of wedge-type centering and clamping mechanism.
Fig. 2 is the work schematic diagram of wedge-type centering and clamping mechanism.
The specific embodiment
As shown in Figure 1, a kind of wedge-type centering and clamping mechanism, along hollow shaft 10 center lines, be arranged with two same apparatus, each device is that wedge axle 2 is flexibly connected with hollow shaft 10, in the wedge axis hole of wedge axle 2, is connected with center sleeve 1, and hollow shaft 10 is flexibly connected with pivoting support 6, pivoting support 6 is provided with spring push-rod 8, the axial line of spring push-rod 8 is vertical with the axial line of hollow shaft 10, and the cylindrical of spring push-rod 8 circular arc end faces and wedge axle 2 is tangent, and the other end is fixedly connected with locating piece 4.
Hollow shaft 10 is provided with long kidney-shaped hole 5 with wedge axle 2 active connection places, between hollow shaft 10 and wedge axle 2, by straight pin 3, is connected, and the position of long kidney-shaped hole 5 is corresponding with straight pin 3 positions.
Embodiment mono-:
During processing equal diameter workpiece, the isodiametric part of required processing is positioned on the upper surface of locating piece 4, the center sleeve of wedge-type centering and clamping mechanism 1 one end is clamped with scroll chuck, the other end makes wedge axle 2 and straight pin 3 move at the mounting hole place of hollow shaft 10, when the both sides locating piece 4 about hollow shaft 10 center line symmetries is in same level, dead center holds out against the other end center sleeve 1 of wedge-type centering and clamping mechanism, completes centering clamping work.
Embodiment bis-:
As shown in Figure 2, while processing anisodiametric workpiece, the anisodiametric part of required processing is positioned on the upper surface of locating piece 4, the center sleeve of wedge-type centering and clamping mechanism 1 one end is clamped with scroll chuck, the other end makes wedge axle 2 and straight pin 3 move at the mounting hole place of hollow shaft 10, when the position of locating piece 4 meets institute's processing parts diameter, with dead center, hold out against the center sleeve 1 of a side, complete centering clamping work.
