The defect of existing grinding core frock is: because tailstock and adapter sleeve are coaxially connected and fixed by a transition piece, so just cause the accumulated error of installation larger, and then it is overproof to cause the conical surface of workpiece to be beated, can not requirement on machining accuracy be reached, be badly in need of solving above-mentioned technical barrier for this reason.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of output shaft of gear-box grinding core frock, for ensure process the beating degree of the output shaft conical surface.
Technical scheme of the present invention is as follows: a kind of output shaft of gear-box grinding core frock, comprise tailstock (1) and adapter sleeve (2), the axial line of these two parts is on same straight line, it is characterized in that: right-hand member and adapter sleeve (2) left end of described tailstock (1) are directly fixed, the left end of this tailstock is fixed with a blanking cover (3), the left side of this blanking cover has central term pointed orifice, and the left part of tailstock (1) outer wall is equipped with first radial direction stirs screw (4); A spring (5) and one top (6) are housed in the centre bore of described tailstock (1) from left to right successively, and wherein spring (5) is clipped between top (6) and described blanking cover (3); The outer wall of described top (6) has vertically stopper slot (6a), the root of radial stop screw (7) snaps in this stopper slot, the head of this radial stop screw (7) is connected with the screwed hole on described tailstock (1), and top (6) right part reaches in the centre bore of described adapter sleeve (2);
Described adapter sleeve (2) the right is provided with the Shifting rack (8) of " Z " font, a flat segments of this Shifting rack and the right part of adapter sleeve (2) outer wall are fitted, and fixed by the radial attachment screw (9) arranged, and another flat segments right part of Shifting rack (8) is installed with second radial direction stirs screw (10), this second radial direction stirs the right side that screw is positioned at described adapter sleeve (2).
Together with tailstock (1) is connected directly between with adapter sleeve (2) by the present invention, and the transition piece eliminated in original structure, this reduces accumulated error, thus the beating degree of workpiece (G) conical surface can be ensured well, and then ensure the machining accuracy of workpiece (G), and the present invention just solves large problem by little change, be suitable for extensively promoting the use.
As preferably, the right-hand member of described tailstock (1) and adapter sleeve (2) left end are fixed by screw (11), and this screw (11) is arranged along the axis of tailstock (1).
Adopt above structure, the present invention can facilitate, securely tailstock (1) and adapter sleeve (2) be directly fixed together, and screw draw materials conveniently, cheap.
As optimal design, the right part of described blanking cover (3) is provided with a roundlet shell of column, and the left part of described spring (5) is enclosed within outside this roundlet shell of column, and spring (5) right part reaches in the mounting groove of described top (6) left side.
Adopt above structure, the present invention can lead to described spring (5) well.
Beneficial effect: together with tailstock (1) is connected directly between with adapter sleeve (2) by the present invention, and the transition piece eliminated in original structure, this reduces accumulated error, thus the beating degree of workpiece (G) conical surface can be ensured well, and then ensure the machining accuracy of workpiece (G), and the present invention just solves large problem by little change, be suitable for extensively promoting the use.
Accompanying drawing explanation
