Abstract

An end surface positioning expanding mandrel for an involute internal spline comprises a tapered mandrel, a locking nut, an end surface positioning plate, sliders, steel wire lock rings, a compression spring, a sliding sleeve, a gasket and a nut. The end surface positioning plate is screwed on threads on the outer side of the large tapered end of the tapered mandrel, then the locking nut is screwed, the compression spring is sleeved outside the small tapered end of the tapered mandrel, the sliding sleeve is further sleeved on the compression spring, the six sliders are mounted into six square grooves evenly distributed on the sliding sleeve one by one, then each two steel wire lock rings are respectively clamped into two grooves of each slider, and finally the gasket is mounted before the nut is screwed on threads at one lateral end of the small tapered end of the tapered mandrel. Expansion procedure is more stable and centering precision is better by the aid of contacting of a conical surface with a slanting surface, and simultaneously, processing and maintenance of the tapered mandrel and sliders are more convenient. The added end surface positioning plate can be used for numerical control machining in batch. The end surface positioning expanding mandrel avoids jamming and facilitates assembling and disassembling parts due to the fact that small-diameter cylindrical surfaces on the outer sides of the sliders contact with a toothed surface of the internal spline.

Description

Involute inner spline is located the mandrel that can rise with end face
Technical field
The utility model belongs to field of machining, relates to a kind of mandrel that rises, and relates in particular to a kind of involute inner spline and locatees the mandrel that can rise with end face.
Background technology
At present, at mechanical processing industry, the mandrel that can rise is widely used in the manufacturing procedures such as car, mill, makes things convenient for the clamping of work piece when the internal-external circle concentricity that guarantees workpiece to be machined requires, is applicable to the processing of part in batches.But at the risen mandrel of internal spline structure often owing to structure is complicated, processing and manufacturing reasons such as difficulty, precision instability can not well be used, therefore need the involute inner spline of a kind of processing simple in structure, convenient and stable accuracy to locate the mandrel that can rise with end face.
The utility model content
The involute inner spline that the purpose of this utility model is to provide a kind of simple in structure, good manufacturability, make things convenient for processing and maintenance and stable accuracy is with the end face location mandrel that can rise.
The technical solution of the utility model is: involute inner spline is located the mandrel that can rise with end face and is comprised: tapering mandrel, locking nut, end face positioning disk, slide block, round wire circlip, compression spring, sliding sleeve, pad, nut; The end face positioning disk is tightened on the screw thread in the big end of the tapering of the tapering mandrel outside, the locking nut of screwing on again, the compression spring housing is in the tapering mandrel tapering small end outside, overlap upper sliding sleeve again, six slide blocks are put in six square grooves that are distributed on sliding sleeve one by one, and then two round wire circlips are stuck in two grooves of each slide block, load onto packing ring at last, again nut is screwed on the screw thread of tapering mandrel tapering small end one side end.
The beneficial effects of the utility model are: the form that adopts the conical surface to contact with the inclined-plane, and make slide block more stable in the process of mobile tensioner workpiece, centering precision is also better.The processing of tapering mandrel and slide block maintenance simultaneously is also convenient.Increase the end face positioning disk, can make the work piece axial location in the tensioner workpiece, conveniently be used for numerical control machine tool, saved the tool setting time of each part, the numerically controlled lathe or the fixture for grinding machine that can be used for processing in enormous quantities use.Use six slide block tensioner workpiece can reduce the distortion of workpiece, six square grooves on the sliding sleeve radially connect in twos and can adopt the mode of the back line cutting of quenching to process simultaneously, improved the processing technology of sliding sleeve, but will be according to being done suitable adjustment by the internal spline number of teeth of tensioner workpiece in actual the use.The slide block outside adopts the small diameter cylinders face to contact with the internal spline flank of tooth, does not have stuck phenomenon, the conveniently assemble and disassemble part.
Description of drawings
Fig. 1 locatees the structural representation of the mandrel that can rise with end face for the utility model involute inner spline.
Fig. 2 locatees the A-A profile of the mandrel that can rise with end face for the utility model involute inner spline.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings below, as Fig. 1～shown in Figure 2, involute inner spline comprises with the end face location mandrel that can rise: tapering mandrel 1, locking nut 2, end face positioning disk 3, slide block 5, round wire circlip 6, compression spring 7, sliding sleeve 8, pad 9, nut 10.
At first end face positioning disk 3 is tightened on the screw thread in the big end of the tapering of tapering mandrel 1 outside, the locking nut 2 of screwing on again, compression spring 7 is enclosed within the tapering mandrel 1 tapering small end outside, overlap upper sliding sleeve 8 again, six slide blocks 5 are put in six square grooves that are distributed on sliding sleeve 8 one by one, and then two round wire circlips 6 are stuck in two grooves of each slide block 5, load onto packing ring 9 at last, nut 10 is screwed on the screw thread of tapering mandrel 1 tapering small end one side end again.
Nut 10 is not twisted too tightly earlier during use, make workpiece 4 have suitable space can be enclosed within on the mandrel, the left side of workpiece 4 is close to end face positioning disk 3, and then fastening nut 10, nut 10 is pushing away sliding sleeve 8 and is sliding left, sliding sleeve 8 drives slide blocks 5 and also slides left, because the effect of tapering mandrel 1 conical surface also outwards rises when slide block 5 is slided left, up to workpiece 4 tensioners.Just can carry out process operations such as car or mill to workpiece 4 then, to guarantee the axiality requirement of processing content and internal spline pitch circle with the top centre bore that heads on tapering mandrel 1 of tailstock tool.After workpiece 4 processes, unclamp nut 10 a little, compression spring 7 promotes sliding sleeve 8 and returns to the right, drives slide block 5 simultaneously and walks to the right, and round wire circlip 6 is pressing six slide blocks 5 to shrink, and unclamps workpiece.
The form that adopts the conical surface to contact with the inclined-plane makes the tensioner process more stable, and centering precision is also better, and the processing of tapering mandrel and slide block maintenance simultaneously is also convenient.Increase the end face positioning disk, can be used for digital control processing work in enormous quantities.The slide block outside adopts the small diameter cylinders face to contact with the internal spline flank of tooth, does not have stuck phenomenon, the conveniently assemble and disassemble part.
