Abstract
The utility model provides a rocking arm axle guiding mechanism, including rocking arm axle, adjusting screw, keep the ware, the tip of rocking arm axle is equipped with the adjusting screw mounting hole, the bottom of adjusting screw mounting hole is arranged in to a thrust gasket, adjusting screw's spacing axle journal keeps the ware to pass through the oral area of threaded connection at the adjusting screw mounting hole among arranging the adjusting screw mounting hole again in to it is spacing the adjusting screw axial, be provided with at least one rivet hole at the tip of rocking arm axle, rivet through the part that corresponds on the terminal surface keeping the ware and seal the rivet hole, form and rivet the structure, realize lockingly. The utility model discloses improved steering gear rocking arm axle guiding mechanism, can integrate steering gear rocking arm axle guiding mechanism of unified each series, the dress of frequently exchanging labour when having avoided each serial rocking arm axle guiding mechanism of processing, adopt substituting the sealing of a rivet hole and rivet the groove, saved the processing cost, adopt rocking arm axle thrust gasket to replace the chock, make and convenient assembling.
Description
Technical field
The utility model relates to a kind of rocker shaft adjusting mechanism of a kind of automobile power steering, particularly automobile power steering.
Background technology
The automobile power steering guiding mechanism size disunity of current each series, the forming tool of processing use is many, and cutter manufacturing cost is high, and technique ensures ability. As depicted in figs. 1 and 2, prior art rocker arm shaft includes rocker arm shaft body 1, adjust screw 2 and be fixed in the chock hole 5 of rocker arm shaft 1 by the chock 3 on top and the retainer 4 of side, chock hole 5 inward flanges are provided with envelope riveting groove 6 and coordinate with adjustment screw 2 outward flanges, play positioning action; Shortcoming has following aspect: 1, the required precision in rocker arm shaft chock hole is high, after rocker arm shaft heat treatment chock hole yielding (mutability is oval); 2, chock has foozle, is difficult for assembling, fragile (squeezed broken); 3, the milling cutter processing cost of rocking arm shaft seal riveting groove processing use is high.
Summary of the invention
High in order to solve existing rocker shaft adjusting mechanism processing cost, the problem of the yielding damage of working, the utility model proposes a kind of rocker shaft adjusting mechanism.
The technical solution of the utility model is: a kind of rocker shaft adjusting mechanism, comprise rocker arm shaft, adjust screw, retainer; the end of rocker arm shaft is provided with adjustment screw mounting hole; it is characterized in that: a thrust washer is placed in the bottom of adjusting screw mounting hole; the spacing axle journal of adjusting screw is placed in to be adjusted among screw mounting hole; retainer is threaded connection at the oral area of adjusting screw mounting hole again, thereby adjusting screw axial limiting; Be provided with at least one envelope rivet hole in the end of rocker arm shaft, by part riveting corresponding on the end face of retainer is entered to seal in rivet hole, form envelope riveting knot structure, realize locking.
Further restriction to technique scheme: be along the circumferential direction laid with 2-3 envelope rivet hole in the end of rocker arm shaft, this is to optimize structure, and has reached reliable anti-loosing effect, is convenient to again practical operation.
Beneficial effect: the utility model has improved steering gear rocker shaft adjusting mechanism, can integrate the steering gear rocker shaft adjusting mechanism of unified each series, while having avoided processing each serial rocker shaft adjusting mechanism, frequently changes frock; Adopt envelope rivet hole to substitute envelope riveting groove, cancelled Milling Process, adopted Drilling operation, saved processing cost; Adopt rocker arm shaft thrust washer to substitute chock, manufacture and easy to assembly, the problem having occurred while having solved chock manufacture, processing and assembling, the problem of also having avoided rocker arm shaft chock hole to be out of shape after heat treatment simultaneously; After redesign, reduced cutter, and be all standard cutter, purchase cost is low.
