The utility model discloses utilize this internal elastic centre of base to carry out axial positioning, utilize the terminal surface of base body to carry out end face positioning simultaneously, just overcome the inconsistent defect of centre bore chamfer of axle type part this moment, dual location has just realized axle type part axiality and axial dimension's accurate location, and the terminal surface closed dimension to a plurality of steps formation of axle type part is also guaranteed very easily, realizes the batch accurate of product.
Description
Technical Field
The utility model relates to an anchor clamps among the industrial design specifically are an anchor clamps of guaranteeing part axiality and axial dimension simultaneously.
Background
In the mechanical processing process, the axial dimension is required to be ensured particularly for shaft parts, the double tips are simultaneously pressed tightly and then processed, the coaxiality can be basically ensured at the moment, but the precision of the closed size of the end face formed by the steps of the part, particularly the closed size of the end face formed by a plurality of steps of a shaft part, namely the axial size, can not be ensured, the reason for this is that the axial size of the center positioning is related to the chamfer angle of the central hole, while the chamfer angle of the central hole of the shaft part is not necessarily standard, at this time, or because of the artificial reason, the chamfer angle of 1mm 60 degrees is required to be changed into the chamfer angle of 1.1mm 60 degrees or 0.9mm 60 degrees and other chamfer angles, the length of 0.1mm can cause the displacement of the closed size between the end surfaces, namely the axial size, and the displacement can be generated by utilizing numerical control processing, so that the closed size of the step forming end surface of the part, namely the axial size, can not be ensured.
Disclosure of Invention
The utility model discloses a guarantee the axiality of processing axle type part, still guarantee that axle type part step forms the closed size of terminal surface and be axial dimension, specially provide one kind and guarantee part axiality and axial dimension's anchor clamps simultaneously.
Therefore, the technical scheme of the utility model be, an guarantee part axiality and axial dimensions's anchor clamps simultaneously, it is top, its characterized in that including the lathe tailstock: the lathe tailstock center is correspondingly provided with an elastic center, the elastic center comprises a base body, the rear part of the base body is connected with a stop block through a screw, the base body is hollow, the center is arranged in the hollow base body, and the center is provided with a conical surface; a connecting screw rod penetrates through the center of the tip, penetrates through the stop block and is connected with the stop block; the connecting screw rod is also sleeved with a spring between the stop block and the tip.
The further improvement lies in that: the base body is step-shaped, wherein the first step is a datum plane, and the second step is connected with the stop block.
The further improvement lies in that: the hollow part of the base body is in transition fit with the excircle of the tip.
The further improvement lies in that: the center is internally provided with a step hole, a spring is contained in the step hole, and the center moves in the hollow base body through the connecting screw rod and the spring.
Has the advantages that:
the utility model discloses utilize this internal elastic centre of base to carry out axial positioning, utilize the terminal surface of base body to carry out end face positioning simultaneously, just overcome the inconsistent defect of centre bore chamfer of axle type part and assembly part this moment, dual location has just realized axle type part and assembly part axiality and axial dimension's accurate location, and the terminal surface closed dimension that forms to a plurality of steps of axle type part and assembly part also guarantees very easily, realizes the batch accuracy of product.
The base body is step-shaped, wherein the first step is a datum plane, and the second step is connected with the stop block. Not only is the connection of intensity, has still guaranteed the accuracy of reference surface, has also lightened weight simultaneously.
The hollow of base body and top excircle are transition fit for letting top have a motion space, and when the part met top, top kick-backed, axial positioning guaranteed this moment, realized the end face location after the terminal surface of part met the reference surface of first step, realized two location.
A stepped hole is formed in the center and can be used for placing a spring, so that the spring has a movement space and a track.
