Description
Technical field
The utility model relates to the special accessory of a kind of Turning of Slender Shaft.
Background technology
We are when turning shaft parts, general adopt folder top installation way, and namely three-jaw presss from both sides one and center hole is bored in other end, then uses top top end face.The processing of this method centering Short Axis Kind of Parts is the axiality improving each form factor, ensures dimensional accuracy effective method, but just undesirable to the processing of the poor thin and long shafts part of rigidity.Due to the rigidity of thin and long shafts part poor (adding cutter relieving in man-hour), distortion is large and add the characteristics such as vibrations in man-hour, and the processing of thin and long shafts part is produce slot always.New technological means head it off is adopted to become inevitable.
Summary of the invention
For solving the problem, the utility model spy proposes the special accessory of a kind of Turning of Slender Shaft, draws installation way (two ends pulling force) to change folder top installation way in the past with one folder.
The special accessory of a kind of Turning of Slender Shaft comprises: three-jaw chuck 1, pull head 2, tail stock, and described three-jaw chuck 1 clamps slender axles one end, and the slender axles other end connects tail stock by pull head 2;
Described tail stock comprises: holder 3, tension seat 4, front fastening bolt 5, rear fastening bolt 6, support 7, tension axle 8, bearing 9, spacer 10, cover plate 11, and tension seat 4 is connected on slide rail bottom support 7 by front fastening bolt 5 athwart; Rear fastening bolt 6 passes perpendicularly through bottom support 7 and is connected on slide rail by holder 3; Tension axle 8 is through the through hole on support 7 top; Bearing 9 and spacer 10 are arranged between tension axle and rack ventilating hole, bear and run up and radial load; Cover plate 11 is positioned at front end, support 7 top, is enclosed within tension axle 8 front end;
Pull head 2 afterbody connects tension axle 8 front end by universal joint 12; Pull head 2 front end connects slender axles one end.
Described pull head 2 has 2 kinds of structures, and one is endoporus pull head, and one is cylindrical pull head.
Described tail stock draws the matching used special tooling of installation way with the folder of thin and long shafts part, each supporting should be relevant to use equipment with interface size.Slender axles are more yielding and cutting force vibrations are comparatively large, therefore adopt universal joint connecting mode to eliminate, and alleviate the destruction of mechanical shock to special purpose lathe tailstock simultaneously.
The three-jaw chuck folder slender axles one of the special accessory of this Turning of Slender Shaft, and slender axles other end drilling radial hole, then be strained to straight line with tail stock and carry out circle product external turning.Two kinds of pull header structure, to guarantee the product blank clamping of inhomogeneity shape, the product clamping of inhomogeneity shape only need change pull head.Product structure spy for inhomogeneity shape carries out classification excircle orientation and Internal hole positioning two kinds of modes, and the product clamping for inhomogeneity shape only need change two kinds of pull header structure, and by power transmission pin driving torque.
The present invention is to the effect of being significantly improved of the crudy of thin and long shafts part and efficiency.

Detailed description of the invention
The utility model spy proposes the special accessory of a kind of Turning of Slender Shaft, draws installation way (two ends pulling force) to change folder top installation way in the past with one folder.Folder draws installation way (two ends pulling force) to be aimed at the processing of the poor thin and long shafts part of rigidity and a kind of special process method of adopting, it and traditional Machining of Shaft-type Parts installation way have the difference of matter, and the distortion precision that is comparatively large and that process vibrations and cause mainly solving thin and long shafts part is difficult to ensure.
1) folder draws installation way and folder to push up installation way to compare and carry out force analysis:
Folder top installation way specifically (Fig. 2), after slender axles clamping, passes to three-jaw chuck by tailstock F2 power, and three-jaw chuck reaction force F1 and F2 makes slender axles centre position bend, and produces F3 with joint efforts.Slender axles are by cutter radial component F4 simultaneously, and under F3 and F4 in the same way superposed force effect, slender axles centre position is bending more serious, will cause cutting position cutter relieving and strenuous vibration, and Product processing difficulty and dimensional accuracy cannot be ensured.
Folder draws installation way specifically (Fig. 3): three-jaw presss from both sides one and other end drilling radial hole, then is strained to straight line with special purpose lathe tailstock of the present invention and carries out circle product external turning.After slender axles clamping, by special purpose lathe tailstock tension F2 power, also produce reaction tensile force f 1 now to three-jaw chuck, make product stretching.When Tool in Cutting, radial load F4 makes slender axles bending and cutter relieving, but under the effect of F1 and F2 power, also produce the F3 that makes a concerted effort, under the reverse superposed force effect of F3 and F4, slender axles centre position is bending to be reduced, form cutting position cutter relieving and strenuous vibration to eliminate, make Product processing smoothly and dimensional accuracy more easily ensure.
2) the special purpose lathe tailstock of this patent is connected with universal joint damping:
Special purpose lathe tailstock (Fig. 4): support location and height dimension are determined so that the lathe equipments used is supporting, front fastening bolt adopts cable-stayed type to be guarantee that support is more adjacent to slide rail and tension product, and rear fastening bolt adopts Straight pull to be guarantee that support is more adjacent to slide rail and tension is more firm.The design strains axle and adopts two large span radial ball bearings to bear and run up and radial load, and adopt a flat thrust ball bearing to bear and run up and axial tension, compact overall structure is efficient.Because slender axles are more yielding and cutting force vibrations are comparatively large, therefore adopt universal joint connecting mode to eliminate, alleviate the destruction of mechanical shock to special purpose lathe tailstock simultaneously.
3) two kinds of pull header structure (Fig. 5,6) of this patent; Because the component structural thousand of reality processing differs from ten thousand different, for guaranteeing the product blank clamping of inhomogeneity shape, product stays long clamping process length, product structure spy for inhomogeneity shape carries out classification excircle orientation and Internal hole positioning two kinds of modes, product clamping for inhomogeneity shape only need change two kinds of pull header structure, and by power transmission pin driving torque.This patent has obvious effect to the crudy of thin and long shafts part and efficiency.
