Abstract
The utility model discloses a clamping mechanism for taking internal spline shaft class part rotating machining, including two top, one of them is top to be fixed on the tailstock of lathe, and another is top to be fixed on the main rotation axis of lathe, top and the aperture of waiting to process the part both ends suit, fixes top front end on the main rotation axis and sets up to the plane, along the inside extension of axial centerline and be equipped with the screw hole, has the external splines shifting block through the mounting screw on the top preceding terminal surface, the internal splines clearance fit of external splines shifting block and waiting to process the part. The utility model discloses an internal spline of part is stirred to external splines shifting block to reach the purpose of the rotatory processing of part, both avoided the heart chuck to the centre gripping of part outer shaft footpath and the part surface damage and the shaft footpath deformation problem that leads to, also solved the problem of part processing of turning round simultaneously.
Description
Technical Field
The utility model relates to an axle type parts machining technical field, concretely relates to a clamping mechanism that is used for rotatory processing of in-band integral key shaft type part.
Background
In the processing of the shaft parts, the spindle is rotated to drive the heart-shaped clamping head, and then the heart-shaped clamping head drives the shaft parts to rotate, so that the processing purpose is achieved.
In the process of implementing the present invention, the inventor finds that there are at least the following problems in the actual processing:
the outer diameter surface of a part of shaft part is not provided with a clamping position, and the part cannot be clamped by using a heart-shaped chuck, so that the working procedure is increased after the part is turned around for processing and is ground again, and the working procedure is prolonged;
secondly, the requirements on the shaft diameter precision and the surface roughness of a part of shaft parts are very strict, and the heart-shaped chuck can damage the roughness of the surface of the part and influence the precision of the part after clamping the part, so that the processing problem cannot be effectively solved.
Disclosure of Invention
In order to solve the tight processing problem of clamp of in-band integral key shaft class part, the utility model provides a clamping mechanism for taking internal key shaft class part spin processing.
Therefore, the technical scheme of the utility model is that: the utility model provides a clamping mechanism for taking internal spline shaft class part spin processing, includes two top, and one of them top is fixed on the tailstock of lathe, and another top is fixed on the main rotating shaft of lathe, its characterized in that:
the front end of the centre fixed on the main rotating shaft is a plane and is provided with a screw hole extending inwards along the axial central line, the front end surface of the centre is provided with an external spline shifting block through a screw, and the external spline shifting block is in clearance fit with an internal spline of a part to be processed.
Preferably, the external spline shifting block comprises a circular shifting block body, spline teeth in clearance fit with the internal spline of the part to be processed are axially and uniformly distributed on the outer peripheral surface of the shifting block body, and a screw mounting hole is formed in the center of the shifting block body.
Has the advantages that: the utility model discloses an internal spline of part is stirred to external splines shifting block to reach the purpose of the rotatory processing of part, both avoided the heart chuck to the centre gripping of part outer shaft footpath and the part surface damage that leads to and the shaft footpath warp the problem, also solved the problem of part processing of turning round simultaneously.

Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings, but the embodiment should not be construed as limiting the present invention.
The utility model discloses as shown in fig. 1 to 5:
a clamping mechanism for rotationally processing parts with an internal spline shaft comprises two centers, wherein one center 5 is fixed on a tailstock 6 of a machine tool, the other center 1 is fixed on a main rotating shaft 7 of the machine tool, and a part 4 to be processed is clamped by the two centers;
the front end of a tip 1 fixed on the main rotating shaft is a plane and is provided with a screw hole extending inwards along an axial central line, an external spline shifting block 3 is installed on the front end face of the tip through an internal hexagonal screw 2, and the external spline shifting block 3 is in clearance fit with an internal spline of a part 4 to be processed.
The external spline shifting block comprises a circular shifting block body, spline teeth which are in clearance fit with the internal spline of the part to be processed are axially and uniformly distributed on the outer peripheral surface of the shifting block body, the purpose of clearance fit is that in order to facilitate installation and disassembly, a screw mounting hole is formed in the center of the shifting block body, and the screw mounting hole is a step hole.
The utility model discloses an internal spline of part is stirred to external splines shifting block to reach the purpose of the rotatory processing of part, avoided the heart chuck to the centre gripping in part outer shaft footpath and the part surface damage that leads to and the shaft footpath deformation problem, also solved the problem of part processing of turning round simultaneously, convenient and practical, the effect is showing.
Those skilled in the art will appreciate that the details of the present invention are not described in detail herein.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
