At present, in practical set process, owing to lacking the orientation tool of each parts, when running in bearings and gear, be difficult to the consistency ensureing gear initial phase, and need to install owing to being same as several parts, often people is difficult to complete a whole set of assembling smoothly simultaneously, cause assembly quality and efficiency of assembling low.
Summary of the invention
The object of the invention is to provide for the problem of above-mentioned prior art the contact assembling tool that a kind of structure is simple, practical, installation accurately also can improve the three-station of efficiency of assembling.
The technical solution used in the present invention is: a kind of contact assembling tool of three-station, comprise a cross section be rectangle and can through the positioning rule of the rectangular through-hole of gear shaft, two for the locating piece that makes bearing align with the installation position of bearing and two for the push pipe by bearing jacking bearing pedestal; The center of two described locating pieces is equipped with the rectangular through-hole that can be slidably matched with positioning rule, during use, locating piece is enclosed within positioning rule by the rectangular through-hole at its center, bearing holder (housing, cover) makes the outer ring of bearing and inner ring position align with bearing pedestal and gear shaft spindle nose respectively on locating piece, the internal diameter of described push pipe is greater than the diameter of gear shaft spindle nose, and external diameter is less than the internal diameter of bearing pedestal.During use, first gear is put into its installation position at contact base, conducting rod is loaded contact base inner chamber, now make gear not engage with the tooth bar of conducting rod, according to the unified assembling standard adjustment position of conducting rod in contact base; Positioning rule is inserted the rectangular through-hole of gear, two pieces of locating pieces are also enclosed within positioning rule respectively by bearing holder (housing, cover) on locating piece, the rectangular through-hole of gear is adjusted to certain angle relative to contact base Uniform provisions by rotational positioning chi, then two locating pieces are promoted bearing is alignd with bearing pedestal along positioning rule to gear, positioning rule is kept no longer to change relative to the angle of contact base in pushing course, now wheel and rack engagement, two push pipes to be enclosed within respectively on locating piece and bearing is headed into bearing pedestal, last mounting spring catch, assembles complete.Being guided by positioning rule and locating piece loads in bearing pedestal by bearing, by originally scrappy parts positioning rule location and installation, easy to operate, and installation accuracy is high.
With improvement, assembly tool of the present invention also comprises one piece of base plate, described base plate is fixed with two pieces of support chips perpendicular to base plate, support chip upper end is the arc coordinated with gear shaft, contact base is placed on base plate, support chip stretches into the rectangular aperture bottom contact base, the arc place, upper end of two pieces of support chips and gear shaft surface contact, and the wheel tooth position of gear is between two pieces of support chips.After loading conducting rod and gear, contact base is placed on base plate, gear is propped up location by support chip, now positioning rule is inserted the rectangular through-hole of gear, is enclosed within positioning rule by two locating pieces, adjustment positioning rule makes wide maintenance level of positioning rule, promoting locating piece makes bearing align with bearing pedestal, remains wide maintenance level of positioning rule in pushing course, now wheel and rack engagement, with push pipe, bearing is headed into bearing pedestal, install.Base plate and support chip are set, contact base and gear are located and remains on the location status of more convenient assembling, having heightened efficiency of assembling.
Described locating piece is cylindrical, and its external diameter equals the external diameter of gear shaft spindle nose.
The invention has the beneficial effects as follows: gear and bearing are positioned at an enterprising luggage of positioning rule and join by the contact assembling tool of three-station of the present invention, avoid the problem of attending to one thing and lose sight of another in original assembling process, have heightened efficiency of assembling; And by the setting angle of positioning rule adjustment gear, not only directly perceived but also facilitate, heighten assembly quality.
