The utility model discloses on drawing forth two adjustable adjustment disks with the required centre bore of work piece finish machining, can be in the quick adjustment centre bore position of smart manufacturing procedure to the axle of high accuracy is processed out, machining efficiency can be obviously improved.

Description

A kind of hard-tooth surface speed reducer axle class machining center hole adjusting device
Technical field
The utility model relates to a kind of axle class auxiliary processing device, specifically a kind of hard-tooth surface speed reducer axle class machining center hole adjusting device.
Background technology
Centre bore is as the accurately machined benchmark of axial workpiece, its precision directly affects the machining accuracy of axial workpiece, especially for the gear shaft of hard-tooth surface speed reducer, need to carry out fine finishining after the heat treatment such as carburizing, quenching, no matter be Excircle machining or the processing of final teeth portion, all need high-precision centre bore as machining benchmark, but the distortion of heat treatment rear axle make original centre bore generation shape be out of shape and position skew, can not be re-used as the fine finishining benchmark of postorder.Usually obtaining high-precision centre bore processing method for axial workpiece is: for draw ratio than little axle, be out of shape less after heat treatment, adopts centre-hole lapping machine bed to carry out grinding center hole; For the axle that draw ratio is larger, because the position degree being out of shape larger original centre bore after heat treatment seriously offsets, therefore need to reserve certain surplus to Workpiece length, machining center hole again after upper lathe centering key position.No matter above traditional processing method is adopt special purpose machine tool grinding center hole or machining center hole again, all there is complex process, time and waste of raw materials, phenomenon that working (machining) efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of hard-tooth surface speed reducer axle class machining center hole adjusting device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of hard-tooth surface speed reducer axle class machining center hole adjusting device, comprise transition axis, adjustment disk and adjustment screw, uniform four screwed holes of circumference on described adjustment disk, one end of described transition axis is arranged in adjustment disk, and leave a fixed gap with adjustment disk inner chamber, described transition axis is by being arranged on adjustment screw in four described screwed holes and adjustment disk is fixed, and the other end of described transition axis is provided with the external screw thread with axle two ends centre bore screw-internal thread fit.
As further program of the utility model: described transition axis and adjustment disk are respectively equipped with two.
Compared with prior art, the beneficial effects of the utility model are: centre bore needed for workpiece fine finishining is drawn out on two adjustable adjustment disks by the utility model, central hole location can be adjusted fast at finishing step, thus process high-precision axle, can working (machining) efficiency be significantly improved.

Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-4, a kind of hard-tooth surface speed reducer axle class machining center hole adjusting device, comprise transition axis 1, adjustment disk 2 and adjustment screw 3, uniform four screwed holes of circumference on described adjustment disk 2, one end of described transition axis 1 is arranged in adjustment disk 2, and leave a fixed gap with adjustment disk 2 inner chamber, described transition axis 1 is fixed with adjustment disk 2 by the adjustment screw 3 be arranged in four described screwed holes, the other end of described transition axis 1 is provided with the external screw thread with axle 4 two ends centre bore screw-internal thread fit, described transition axis 1 and adjustment disk 2 are respectively equipped with two, two transition axises 1 with tapering are connected with the C type centre bore at axle 4 two ends respectively, adjustment disk 2 with centre bore to be contained on transition axis 1 and to leave certain adjustable clearance, the two top centre bores withstanding two adjustment disks 2 respectively of cylindrical or gear-shaping machine bed head frame 5 and tailstock 6, adopt four adjustment screws 3 on adjustment disk 2, axle 4 is adjusted, the requirement position cylindrical of axle 4 is beated and reaches technological requirement, usually beat within centering required precision reaches 0.05mm for hardened face gear axle two ends pitch circle, flank of tooth hardened layer uniformity requirement after the follow-up roll flute of guarantee.
First the utility model makes two band taper transitions axles 1 consistent with axle 4 centre bore, transition axis 1 is connected on the C type centre bore of axle two ends, make the adjustment disk 2 of two uniform four screwed holes of circumference again, the endoporus of adjustment disk 2 leaves certain interval with the cylindrical of transition axis 1, adjustment disk 2 is contained on transition axis 1, the centre bore that to utilize on machine tool headstock 5 and tailstock 6 top withstands adjustment disk 2 by axle 4 axially to fixing, dial gauge is fixed on platen, rotational workpieces, the adjustment screw 3 on two ends adjustment disk 2 is adopted to adjust the circular runout deviation that axle 4 reaches expection, this ensures that there axle 4 within the scope of form and position tolerance with the centre bore of adjustment disk for benchmark turns round, cylindrical or teeth portion processing is carried out by lathe driving shaft.Repair grind or machining center hole process procedure again owing to saving centre bore, and more conveniently on lathe, adjustment centering is carried out to axle, therefore namely this center hole adjusting device ensure that the machining accuracy of part is improved the quality of products, and simplifies technical process simultaneously, enhances productivity.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
