Abstract
The utility model provides a hydraulic elastic self-centering structure, which is capable of guaranteeing roundness of 0.005-0.008mm for turned inner holes and simultaneously improving the processing efficiency and reducing the production cost. The hydraulic elastic self-centering structure comprises a flanged disc and is characterized in that a locating sleeve is fastened on the flanged disc, the locating sleeve is provided with a taper opening, an elastic chuck is installed on the inner end of the locating sleeve in a clearance fit manner, the taper part of the elastic chuck is cooperatively sleeved in the taper opening of the locating sleeve, a through hole is processed at the center of the elastic chuck, a transitional sleeve is sleeved on the excircle of a part, the rear end face of the part is press mounted on the front end face of a locating block, a pull rod of a hydraulic oil cylinder is installed at the center of the part, the elastic chuck is cooperatively sleeved on the excircle ring surface of the locating block, a gap is reserved between the excircle ring surface of the transitional sleeve and the inner wall of the elastic chuck, and the centers of the elastic chuck, the flanged disc and the locating sleeve are located on the same axial line.
Description
Technical field
The utility model relates to the technical field of structures of turning location, is specially a kind of hydroelastic system self contering structure.
Background technology
Existing turning centralizer adopts Three-jaw fixture, and service speed is slow, working (machining) efficiency is low, and the self-centering precision is low, can not reach the required precision of 0.010mm, reach the product more than the required precision of 0.010mm for needs, need additional processing, increased production cost.
Summary of the invention
For the problems referred to above, the utility model provides a kind of hydroelastic system self contering structure, and it can satisfy endoporus circularity 0.005-0.008mm after the turning, has improved simultaneously working (machining) efficiency, reduces production costs.
A kind of hydroelastic system self contering structure, its technical scheme is such: it comprises ring flange, it is characterized in that: the fastening positioning sleeve of described ring flange, described positioning sleeve is with the tapering opening, collet is equipped with in the gap of inner end cooperation of described positioning sleeve, being loaded in the tapering opening of described positioning sleeve with tapering part engage sleeves of described collet, the center of described collet has through hole, spacer shell is set in the cylindrical of part, the rear end face of described part press-fits the front end face in described locating piece, the pull bar of hydraulic jack is equipped with at the center of described part, described collet engage sleeves is loaded on the cylindrical anchor ring of described locating piece, leave the gap, described collet between the cylindrical anchor ring of described spacer shell and the inwall of described collet, ring flange, being centered close on the same axis of positioning sleeve.
It is further characterized in that: described spacer shell is specially the elastic opening cover;
Block is by the end flange face of bolted in described positioning sleeve.
After adopting the utility model, spacer shell is enclosed within on the cylindrical of part, in part pushes collet, the part rear end face contacts the location with the axial location piece, when moving backward, the lathe oil cylinder drives pull bar and collet, because the centering of the tapering of collet clamps spacer shell and part backward after the motion, realize that self-centering steps up, and consider the loading and unloading problem of workpiece, have the gap between spacer shell and elastic jacket, after machining, the lathe oil cylinder travels forward, drive pull bar, collet forward, until after clamping force comes up, take off part and spacer shell, operation machines; It can satisfy endoporus circularity 0.005-0.008mm after the turning, has improved simultaneously working (machining) efficiency, reduces production costs.
