Description
Technical field
The utility model patent relates to a kind of shaving mandrel, relates in particular to a kind of ringfeder formula shaving mandrel that is used for shaving processing.
Background technology
Present shaving is processed, and adopts the shaving frock of dead mandrel.Part is packed into behind the mandrel, and has certain clearance between the mandrel, and parts fixation is eccentric easily, causes the profile of tooth teeth directional defective, and accumulation is beated big, finally causes the experiment of transmission assembly noise defective.
Chinese patent CN201020302275.8 discloses the processing of a kind of automobile gear specific purpose tool, the particularly bipyramid formula Fixture for Gear-shaving that can rise.Technical scheme is to comprise shaving mandrel, bipyramid ringfeder, snap ring, gland, spring, tapered sleeve, connecting pin, and the bipyramid ringfeder is contained in by middle inner hole sleeve on the cylindrical of shaving mandrel, is fixed on the shaving mandrel by connecting pin; Spring housing is on tapered sleeve, and gland is enclosed within on the tapered sleeve, and snap ring is stuck in gland on the tapered sleeve, is slidingly connected between gland and the tapered sleeve.This structure relative complex, and the operation have certain inconvenience, thereby on certain degree, influence the frock quality.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provide a kind of elastic expansion-sleeve under the top effect of lathe by spreading, reduce the gap between part and the mandrel, thereby guaranteed the ringfeder formula shaving mandrel that is used for shaving processing of the quality of part shaving processing.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of ringfeder formula shaving mandrel that is used for shaving processing, comprise left press mechanism and right press mechanism, described left press mechanism comprises left gland, spring, tensioner compression plate, left back-up ring clip and left positioning disk, be provided with central shaft in the described left gland, be with the tensioner compression plate on the central shaft, be provided with spring between described tensioner compression plate and left gland, described central shaft is provided with left back-up ring clip, and described left gland and left positioning disk are fixedly connected; Described right press mechanism comprises right gland, elastic expansion-sleeve, back-up ring, right back-up ring clip and right positioning disk, be provided with recessed axle in the described right gland, described recessed axle is complementary with central shaft, be with elastic expansion-sleeve on the described recessed axle, described recessed axle is provided with back-up ring, described right back-up ring clip and back-up ring are complementary, described elastic expansion-sleeve and the corresponding distribution of tensioner compression plate, described right gland and right positioning disk are fixedly connected, described right positioning disk and the corresponding distribution of left positioning disk, the head of described recessed axle is taper.
Left side gland assembling: be screwed into screw in the ringfeder compression plate, the spring of packing in left gland is aimed at the ringfeder compression plate that assembles the aperture of left gland and is packed into, refills the back-up ring clip, prevents that the ringfeder compression plate from skidding off.At last left positioning disk is packed into, load onto holding screw.
Right gland assembling: anti-the rising of at first packing on right gland split pad, reinstalls elastic expansion-sleeve, adorns back-up ring and back-up ring clip then, so that elastic expansion-sleeve can not skid off.At last right positioning disk is packed into.
Operation principle: part is packed in this shaving mandrel, be put into gear shaving machine top on, toply promote left gland and right gland relative motion by shaving mandrel two ends centre bore.Left side gland promotes the ringfeder compression plate by spring, the ringfeder compression plate is delivered to elastic expansion-sleeve with power, because the contact-making surface of elastic expansion-sleeve and right gland is a conical surface, elastic expansion-sleeve in this relative motion process by spreading, reduced and part between fit clearance, thereby the precision of shaving processing is improved.
As preferably, described elastic expansion-sleeve and recessed between centers are provided with anti-rising and split pad.
As preferably, described central shaft and left gland are integrated, and described left back-up ring clip keeps off mutually with the tensioner compression plate and connecing, described spring and the crimping mutually of ringfeder compression plate; Described back-up ring keeps off mutually with elastic expansion-sleeve and connecing, and described recessed axle is integrated with right gland.
As preferably, described ringfeder compression plate and left gland are fastened by housing screw, and described left gland and left positioning disk are fastened by left dog screw, and described right positioning disk and right gland are fastened by right dog screw.
Therefore, the ringfeder formula shaving mandrel that is used for shaving processing of the present utility model improves the precision of processing, promotes the quality of product.
