Description
Technical field
The utility model relates to a kind of mechanical tooling device, the erection unit of the bearing on particularly a kind of control rocking arm of automobile engine cylinder inlet and exhaust valve.
Background technology
In the automobile engine, the rocking arm that control cylinder inlet and outlet door is opened and closed is a lever construction; there is rocker shaft hole at the middle part of rocking arm; there is the forked axle bearing outer end of rocking arm; on the forked axle bearing dead eye is arranged; the axis of dead eye is parallel with the axis of rocker shaft hole, and it is link with valve that the rocker bearing that matches with cam, the inner of rocking arm are arranged on the forked axle bearing.During work, the rocker shaft hole at rocking arm middle part is enclosed within on the rocker arm shaft, and as the fulcrum of lever, rocker bearing is attached on the cam, when cam rotates, promotes the rocking arm periodic oscillations, and periodic oscillations are also done in the inner of rocking arm, and performance period, ground was to the Kai Heguan of cylinder inlet and outlet door.Rocker bearing is to be clipped in the forked axle bearing, and the dead eye on brearing bore and the forked axle bearing is installed with minor axis, and rocker bearing is fixed on the rocking arm.For rocker bearing being installed in the rocking arm outer end, to be placed on rocker bearing in the forked axle bearing earlier, dead eye on brearing bore and the forked axle bearing aligns, even the dead in line of the dead eye on brearing bore and the forked axle bearing, again the dead eye of minor axis from the forked axle bearing penetrated, eject the cylindrical rubber core in the rocker bearing, minor axis is inserted in the dead eye and brearing bore on the forked axle bearing.In the prior art, there is not special-purpose rocker bearing erection unit.Because the dead eye on minor axis and the forked axle bearing is an interference fits, the axis of the dead eye on brearing bore and the forked axle bearing is aligned to be overlapped, again the minor axis that inserts is imposed the power that is pressed into of suitable size, it is very difficult with common instrument rocker bearing to be installed on rocking arm, not only production efficiency is low, and the qualification rate of product is not high yet.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of easy for installation, production efficiency is high, the rocker bearing erection unit that the qualification rate of product is high.
The utility model is realized with the following method.
Rocker bearing mounting equipment has hand to remove forcing press and rocking arm jig; Hand is removed the base plate that forcing press has level; Rocking arm jig pressing plate is arranged on the base plate; The armstand vertical with base plate arranged on the base plate; Vertical tubular slideway is arranged on the armstand; Have and to go up in the tubular slideway; The cylindrical rack of lower slider; There is cylindrical push rod the cylindrical rack lower end; The gear that matches with tooth bar is arranged on the armstand; The handle that is connected with mass is arranged on the axle of gear; The rocking arm jig has the base of level; Cylindrical alignment pin and the positioning sleeve vertical with base are arranged on the base; The external diameter of cylindrical alignment pin matches with the aperture of the rocker shaft hole of rocking arm; The lifting alignment pin circular hole vertical with base arranged in the base; Cylindrical lifting alignment pin is arranged in the lifting alignment pin circular hole; There is helical spring cylindrical lifting alignment pin lower end; Stretch out above base the upper end of cylindrical lifting alignment pin; The external diameter of cylindrical lifting alignment pin matches with the aperture of the dead eye of the forked axle bearing of rocking arm; Rocking arm jig upper; Hypomere has respectively vertical with base upper; Lower through-hole; There is the rocker bearing locating hole of side opening in the stage casing; On; The axis of lower through-hole and rocker bearing locating hole is on same straight line; Cylindrical lifting alignment pin above the protuberate basic unit stretches out the hypomere through hole of rocking arm jig; The rocking arm jig is removed rocking arm jig pressing plate on the forcing press horizonal base plate with hand and is fixed on hand and removes on the forcing press horizonal base plate, rocking arm jig upper; There is the axis of cylindrical push rod the axis of lower through-hole and cylindrical rack lower end on same straight line.
During use, the rocker shaft hole of rocking arm is enclosed within on the cylindrical alignment pin of the present utility model, the dead eye of forked axle bearing is enclosed within on the cylindrical lifting alignment pin of the present utility model, rocker bearing is inserted in the forked axle bearing from rocking arm jig stage casing side opening, spacing by the rocker bearing locating hole, in the epimere through hole of rocking arm jig, put into minor axis, this moment the cylindrical rack lower end cylindrical push rod; the minor axis in the rocking arm jig epimere through hole; the axis of the cylindrical lifting alignment pin in the rocker bearing in the rocker bearing locating hole and the rocking arm jig hypomere through hole is on same vertical straight line; move hand and remove the forcing press handle; cylindrical rack glides; the cylindrical push rod of cylindrical rack lower end is pressed minor axis downwards; allow minor axis along above-mentioned vertical straight line to lower slider; the dead eye of minor axis from the forked axle bearing penetrated in the rocker bearing; eject the cylindrical rubber core in the rocker bearing; minor axis is inserted in the dead eye and rocker bearing on the forked axle bearing; promote the lifting alignment pin simultaneously and descend; the compressing helical spring, finish bearings mounted operation on rocking arm.Rocking arm behind the installation bearing is taken off from the rocking arm jig, and helical spring recovers the original length, and the lifting alignment pin rises, and inserts again in the rocking arm jig hypomere through hole.
The utility model is installed rocker bearing with special equipment on rocking arm, installment work is very convenient, and the qualification rate of production efficiency and product is all higher.
Below in conjunction with accompanying drawing, the utility model is further described.
