Abstract
The invention specifically discloses a gear part shaving fixture which solves the problems that due to the fact that an existing tool for a gear part is large in positioning gap during unthreaded hole centering, a gear is poor in tooth shape and tooth direction. The gear part shaving fixture comprises a left mandrel assembly and a right mandrel assembly. The left mandrel assembly comprises a left base. A mandrel body is fixed to the center of the left base. The right end of the left base is connected with a hollow left positioning base. A pressing cushion is arranged in the left positioning base. A pressing ring is arranged on the right side of the edge of the pressing cushion. A left snap spring is arranged on the mandrel body. A tension spring is arranged in the left base. The right mandrel assembly comprises a stepped right positioning base. A conical sleeve is arranged on the left end face of the right positioning base. The inclined face of the conical sleeve is sleeved with a spring sleeve. The conical sleeve is sleeved with a limiting cushion. A right snap spring is arranged at the left end of the limiting cushion. A limiting pin is arranged on the right side of the spring sleeve. The problem that displacement is prone to happening when force is borne in the axial direction is solved, the turning difficulty is lowered, and the shaving accuracy is improved.
Description
Technical field
The present invention relates to gear part processing tool, be specially a kind of gear part Shaving Process fixture.
Background technology
Existing gear part Shaving Process fixture adopts unthreaded hole centering, because during endoporus turning, size has fluctuation, when deviation appears in hole size, positioning gap is excessive, causes form of gear tooth teeth directional poor, affects gear shaving precision.
Summary of the invention
The present invention adopts unthreaded hole centering to there is the problem that positioning gap causes more greatly form of gear tooth teeth directional poor to solve existing gear part frock, provides a kind of gear part Shaving Process fixture.
The present invention adopts following technical scheme to realize: gear part Shaving Process fixture, comprise be arranged on gear shaving machine left and right top between left axle assembly and right axle assembly; Left axle assembly comprises stepped left pedestal, the center of left pedestal is fixed with axle body, left pedestal right-hand member is connected with hollow left positioning seat, pressure pad is provided with in left positioning seat, pressure pad is provided with pressure ring on the right side of edge, axle body is provided with the left jump ring be positioned on the right side of pressure pad, in left pedestal, is provided with the tensioner spring contacted with pressure pad; Right axle assembly comprises stepped right positioning seat, the left side of right positioning seat is provided with the taper sleeve be enclosed within axle body, on the inclined-plane of taper sleeve, cover has the spring housing corresponding with pressure ring position, and cover has the spacing pad being close to spring housing left side on taper sleeve, the left end of spacing pad is provided with the right jump ring be enclosed within taper sleeve, and the right side of spring housing is provided with the spacer pin be plugged on taper sleeve.
When carrying out shaving operation, gear part is close on right positioning seat through spring housing, then axle body is penetrated taper sleeve, drive left positioning seat to be close to gear part left side, utilize two of gear shaving machine top pressure, make left positioning seat and right positioning seat compress gear part end face; Simultaneously, pressure pad promotes pressure pad and pressure ring holddown spring cover under the effect of tensioner spring, make spring housing tensioner gear part endoporus, thus realize axle cylindrical and inner bore of part gapless is located, overcome the problem that existing gear part frock adopts unthreaded hole centering to there is positioning gap to cause more greatly form of gear tooth teeth directional poor.
Reasonable in design of the present invention is reliable, felt relieved by spring housing, easily occurs the problem of displacement, reduce the difficulty of turnery processing, and improve the precision of Shaving Process when stopping axially stressed, has simple, the easy to process and advantage that cost is low of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: the left pedestal of 1-, 2-axle body, the left positioning seat of 3-, 4-pressure pad, 5-pressure ring, the left jump ring of 6-, 7-tensioner spring, the right positioning seat of 8-, 9-taper sleeve, 10-spring housing, the spacing pad of 11-, the right jump ring of 12-, 13-spacer pin.
