Description
Technical field
The utility model belongs to Automatic manual transmission workpiece technical field, particularly turbine case by-passing valve axle sleeve orientation extruding retaining mechanism.
Background technology
Turbocharger for gasoline engine is the folding by turbine case by-passing valve, changes the operating efficiency of turbocharger.When assembling use; the axis body of turbine case by-passing valve is through axle sleeve; be weldingly connected with the swing arm outside turbine shroud; axle sleeve now needs press-in turbine case axis hole; turbine case axis hole mouth place is extruded with locking axle sleeve simultaneously; and have status requirement to extruding impression; in technological requirement; the direction of extrusion is for becoming 80 ° to distribute with turbine case flange face of giving vent to anger; two impressions 180 ° are uniform, nip width 4.03MIN, but in operation assembling process; usually there will be impression uneven, unsteady situation is installed, thus affect total quality.
Summary of the invention
Main purpose of the present utility model is the design feature for turbine case body and by-passing valve axle sleeve, work out one can with treat workpiece pressing entirety adapts to, and realize quick assembling orientation extrude retaining mechanism.
For achieving the above object, technical solution adopted in the utility model is: turbine case by-passing valve axle sleeve orientation extruding retaining mechanism, described mechanism is made up of targeting part and pressure head two parts, described targeting part is connected by guide finger with described pressure head, described targeting part comprises location-plate and the alignment pin that is arranged on location-plate and adsorption piece, described location-plate is provided with to guide groove, the flange screwed hole of giving vent to anger of the corresponding turbine case of described alignment pin.
Described adsorption piece is magnetic cylinder, and described magnetic cylinder is embedded in described location-plate, makes location-plate be adsorbed in turbine case flange face.
One end of described guide finger and described pressure head interference fit, the other end puts into the gathering sill on described location-plate.
The inner surface of described pressure head and the external cylindrical surface of described turbine case axle sleeve projection adapt.
Described alignment pin and described adsorption piece are two one group.
Described pressure head material adopts high-carbon-chromium bearing steel GCr15.
Extruding retaining mechanism of the present utility model in use, is coordinate forcing press to carry out extruding locking to turbine case axle sleeve.When carrying out assembly manipulation, first workpiece is fixed on forcing press, by-passing valve is put into turbine case axle sleeve hole, and then axle sleeve is put into and stretch out on the bypass valve shaft of turbine case, axle sleeve is pressed in turbine case axle sleeve by operating pressure machine.After axle sleeve is pressed into place, the alignment pin on location-plate is inserted turbine case and gives vent to anger in screwed hole that flange specifies, the adsorption piece that location-plate is bumped into makes location-plate and the laminating of turbine case flange face, and wherein, alignment pin and adsorption piece are one-to-one relationship.
Subsequently pressure head is inserted in the projection of axle sleeve, the gathering sill on location-plate put into by guide finger simultaneously, and starting pressure machine has pressed down extruding locking axle sleeve again, just can complete whole assembling process.After application the utility model, the extruding locking operation simple and fast that whole workpiece is assembled, and steady quality, impression is even, makes the working (machining) efficiency of this operation improve 2 ~ 3 times, mechanism's materials'use high-carbon-chromium bearing steel, durable in use, not fragile, make the manufacturing cost of whole operation comprehensively reduce more than 50%, the requirement of batch production can be met, should be widely promoted and use.

Detailed description of the invention
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, turbine case by-passing valve axle sleeve orientation extruding retaining mechanism, mechanism is made up of targeting part and pressure head 1 two parts, targeting part is connected by guide finger 2 with pressure head 1, targeting part comprises location-plate and the alignment pin that is arranged on location-plate and adsorption piece, and alignment pin and adsorption piece are two one group.
In the present embodiment, adsorption piece is preferably magnetic cylinder, and targeting part is made up of location-plate 4, two alignment pins 5, two magnetic cylinder 3, location-plate 4 is provided with to guide groove; Two alignment pins 5 to be given vent to anger flange screwed hole location with turbine case, and two magnetic cylinder 3 are bumped into location-plate 4, ensure that location-plate 4 is adsorbed on turbine case flange face.Guide finger 2 one end and pressure head 1 interference fit, the other end puts into the gathering sill on location-plate 4, and pressure head 1 protrudes the external cylindrical surface location of turbine case with axle sleeve simultaneously.
In pressure head 1 inner surface, the shape of crimping section is by requirement design workpiece extruding impression, and two seamed edges are symmetrical by 180 °, and ensure the uniformity of extruding, the impression uniformity avoiding artificial deviation to cause is poor.
Pressure head material adopts high-carbon-chromium bearing steel GCr15, heat treatment hardness to 55 HRC ~ 63HRC, ensures the wearability of extrusion edge.
The utility model mechanism coordinates forcing press to extrude turbine case 6, locking axle sleeve 7.When carrying out assembly manipulation, workpiece is fixed on forcing press, by-passing valve 8 is put into turbine case axle sleeve hole, then axle sleeve is put into and stretch out on the bypass valve shaft of turbine case, axle sleeve is pressed in turbine case axle sleeve by operating pressure machine.After axle sleeve is pressed into place, the alignment pin of two on location-plate 45 is inserted turbine case and gives vent to anger in two screwed holes that flange specifies, two magnetic cylinders 3 that location-plate 4 is bumped into make location-plate 4 and the laminating of turbine case flange face.Pressure head 1 is inserted in the projection of axle sleeve, the gathering sill on location-plate 4 put into by guide finger 2 simultaneously, and starting pressure machine has pressed down extruding locking axle sleeve again.
Above-mentionedly be embodied as the good embodiment of the utility model, but embodiment of the present utility model is by the restriction of above-mentioned enforcement, other any change not deviating from utility model works principle, is included within protection domain of the present utility model.
