Description
Technical field
The utility model relates to a kind of mould, especially for the gasoline engine crank timing gears press mounting die that timing gears is fitted on the gasoline engine crank.
Background technology
Be fixed with timing gears on the gasoline engine crank, these timing gears and gasoline engine crank interference fit, and timing gears circumferentially have higher status requirement with respect to bent axle on bent axle, in process of production, timing gears are to be fitted on the bent axle by mould.
Existing gasoline engine crank timing gears press mounting die is when press-fiting timing gears, and the location of timing gears and bent axle is by artificial grasp, and the human factor influence is too big, thereby makes the location of workpiece unreliable.And timing gears are easy to generate displacement in press-fiting process, make the qualification rate lower (as long as press-fit qualification rate 85%～90%) that press-fits the back bent axle, press-fit troublesome poeration, press-fit that process need three people are collaborative to operate, and production efficiency is low.
The utility model content
The purpose of this utility model provides a kind of gasoline engine crank timing gears press mounting die, and when press-fiting, the location of timing gears and bent axle is reliable, and only needs one man operation can press-fit qualified gasoline engine crank product.
Gasoline engine crank timing gears press mounting die described in the utility model, comprise cope match-plate pattern, lower bolster, guide pin bushing and guide pillar, on guide pillar, be set with pressing plate, pressing plate is between cope match-plate pattern and lower bolster, by sliding sleeve and guide pillar matched in clearance, offer with the pressing plate leading edge in the anteriomedial of pressing plate and to be communicated with, and the bent neck locating slot that can cooperate with bent collar crack, also be set with the compression spring on the guide pillar, its upper end acts on the lower end of sliding sleeve, be fixed with gag lever post in the lower bolster both sides, its upper end is hook-shaped, is positioned at the pressing plate top to stop pressing plate up under the compression spring action; Be fixed with briquetting at the cope match-plate pattern lower surface, briquetting be positioned at pressing plate directly over, on lower bolster, be fixed with slide rail, slide block is installed on the slide rail, offer the bent axle via hole on the slide block, it can only move along the mould fore-and-aft direction on slide rail, be fixed with the gear positioning sleeve on slide block, the centre bore of gear positioning sleeve is the stepped hole with counterbore, and this counterbore can press-fit the timing gears matched in clearance with plan, from the mould fore-and-aft direction, the axis of bent neck locating slot coincides on the axis of counterbore and the pressing plate; Gear positioning sleeve upper surface is fixed with the tooth card, tooth on the tooth card termination can be meshed with the tooth of timing gears, its position on the gear positioning sleeve should be satisfied: the counterbore that is arranged in the gear positioning sleeve when timing gears, and the tooth at its timing marks place is with after the tooth card is meshed, bent axle is vertically inserted in the centre bore of timing gears, from the mould fore-and-aft direction, when crankshaft center line and bent neck axis coincided, timing gears were in normal place on the bent axle circumferencial direction.
Described slide rail is made up of two rectangular blocks along the parallel placement of mould left and right directions, is fixed with connecting plate in its back-end, is connected with stop screw towards the slide block direction on the connecting plate, and stop screw is positioned at the same plane parallel with lower bolster with slide block.The effect of stop screw be at slide block when the slide rail shift-in is to mould, in order to the displacement of restriction slide block.
Timing gears press-fiting on bent axle operated as follows:
Earlier slide block outwards is moved to mould the place ahead together with the gear positioning sleeve along slide rail, timing gears are put into the counterbore of gear positioning sleeve, and make the tooth and the engagement of the tooth card on the gear positioning sleeve at place, timing marks place on the timing gears, thereby finish the location of timing gears on mould.
Afterwards, bent axle inserted in the timing gears centre bore (be not seated, make bent axle and timing gears centre bore keep pine to contact), with slide block together with the gear positioning sleeve along the slide rail shift-in to mould, in this process, turning crankshaft enters in the bent neck locating slot of pressing plate the bent neck of bent axle, thereby finishes the location (mid portion of pressing plate is just between two cranks of bent axle at this moment) of bent axle.
Step on motivation bed switch pedal, then cope match-plate pattern is descending along guide pillar, and it is descending to make briquetting press pressing plate, and the crank that pressing plate presses the bent axle below again moves down bent axle, thereby timing gears are fitted on the bent axle.
Afterwards, briquetting is up in company with cope match-plate pattern, makes pressing plate up at compression spring action lower edge guide pillar, keeps out and stops until limited bar upper end.Slide block outwards is moved to mould the place ahead (bent axle that has press-fited timing gears together is moved out of outside the mould) together with the gear positioning sleeve along slide rail in the gear positioning sleeve, bent axle can be taken out from the gear positioning sleeve, thereby finish timing gears press-fiting on bent axle.
Utilize press mounting die described in the utility model to carry out press-fiting of timing gears, timing gears and the bent axle location on mould is convenient and reliable, timing gears can not produce displacement when press-fiting, press-fit the qualification rate height, can reach 100%, and press-fit simple to operationly, only need a people to finish and press-fit operation.
