Description
Technical field the utility model relates to a kind of auto parts and components.
Background technology constant speed center fork assembly is mainly used on the driving shaft in the axial joint of high gear vehicle, it includes a lot of parts, constant speed center fork yoke is again one of them main parts size, its structure is roughly as follows: it has a ring bodies that is sphere, this ring bodies is provided with two end faces parallel and symmetrical with its axis, this both ends of the surface part is respectively established again to be connected as a single entity with it and is extended to both sides, and the earhole part that the extension is parallel with ring axis, through hole is established at the seam middle part of this earhole part.The through hole processing of this contour symmetry is very difficult, because this component shape complexity does not have reliable datum level, loses the location benchmark and just be difficult to reach required precision in processing repeatedly.The external general Digit Control Machine Tool that adopts is processed, its cost height, and profit is too low; And adopt machine tool processing, not only the process-cycle long, difficulty of processing is big, the quality precision can't guarantee, and the product that processes does not have profit.
The summary of the invention the purpose of this utility model is to provide a kind of and constant speed center fork yoke accurately can be located on machine tool, cost is low, the mold of the processing constant speed center of up-to-standard products fork yoke so that process expeditiously accurately and reliably for clamping.The utility model mainly is made up of bent plate, mold body, alignment pin, clamping pressing plate, positioning body, pinching screw, pressing plate and calibration body.Wherein bent plate is the L-square that is connected together and constituted by level board and vertical plate, preferably is provided with reinforcement between the two.Be provided with through hole on the level board of bent plate, the securing member that is located in this through hole can be solid on lathe with bent plate.The vertical plate outside of bent plate is provided with the mold body, and it has a disc-shaped base, and this base is provided with central through hole, and it is corresponding with the screw on the bent plate vertical plate.The perisporium of an above-mentioned base and a specially-shaped annular body is connected as a single entity, and both constitute the mold body.The part that this abnormal shape ring bodies is corresponding with base plate through holes is also established through hole, and the alignment pin bottom is positioned at special-shaped ring bodies, and the other end passes special-shaped ring bodies, base successively and is threaded with screw on the vertical plate, and the end top of passing vertical plate is fastening by nut.This alignment pin can be movably connected in the mold body on the vertical plate of bent plate.Also be evenly equipped with the pressing plate of assist location finger setting on the vertical plate of bent plate, this part can place the pressing plate on the base, and another part is movably connected on the vertical plate of bent plate by securing member.The special-shaped ring bodies of mold body is vertical state in the limit, two ends when work, motionless for guaranteeing to add for twice the man-hour chassis, on base, be provided with two radially slit openings, they are symmetry with the base center of circle, these two slit openings can be corresponding with index pin respectively, index pin is placed in the slit opening, and this calibration body that is provided with index pin is fixed on the vertical plate by securing member.The special-shaped ring-type body profile of above-mentioned mold body is not limit, but interior annular shape matches with constant speed center fork yoke ring bodies profile basically, and an end face of constant speed center fork yoke is with adjacent at the bottom of the alignment pin, and another end face contacts with the clamping pressing plate.This is located in the special-shaped ring bodies and can withstands on the end that clamping pressing plate on the fork yoke of constant speed center is fixed on pinching screw, and this pinching screw passes the screw other end on the special-shaped ring bodies, and to be positioned at special-shaped ring-type external fastening by nut.This screw and above-mentioned dowel hole coaxial line.Also be provided with positioning body on mold body base, it has a column, and this column is established semicircle open slot towards the one side of the special-shaped ring bodies of mold body, and itself and constant speed center fork the yoke outer rim of earhole up and down match.The stiff end of this column is provided with it and is connected as a single entity to the engaging lug of both sides extension, on engaging lug, be provided with through hole, its can be respectively be located at base on be that the two symmetrical groups screw is corresponding with the base center, establish in the through hole of engaging lug positioning body be movably connected in trip bolt on the base.Best above-mentioned through hole is a strip through-hole, makes semicircle open slot position adjustable, can not only make the work piece location accurately, and can also process the yoke of other specification.Though this positioning body profile is not limit its distance of part should be less than the distance of pressing plate from base axis forefield farthest from base axis, so just do not hinder the mold body to rotate.On position corresponding on the base, respectively establish a slotted eye or through hole in addition, be the feed hole with workpiece two earholes.
Process with above-mentioned mold processing constant speed center fork yoke is as follows substantially; 1 on workpiece end face is drawn the earhole position; 2 place workpiece in the mold body that pressing plate steps up, and earhole is close to simultaneously on positioning body up and down, tightens pinching screw, make to clamp pressing plate and be pressed on the end face of workpiece; 3 positions according to the adjustment of the earhole position on workpiece end face positioning body; Two earholes up and down of 4 first processing work one sides, unclamp two pressing plates then, transfer to index pin, the mold body is rotated 180 °, make the workpiece opposite side up and down two earholes move on to the position in preceding two holes, insert index pin, tighten the pressing plate securing member, positioning body is moved on on the position corresponding with processed earhole, the process that repeats preceding two holes can obtain meeting the product of specification requirement again.
The utility model compared with prior art has following advantage:
1, having solved machining does not have the problem of location benchmark, thereby has realized processing constant speed center fork yoke on machine tool, and the product that processes meets every technical indicator fully.
2, process is simple, the cycle is short.
3, processing cost is low, and is considerable because of being its profit of consumable accessory.
