The utility model is to solve its technical problem by following technical solution: a kind of timing chain guard oil sealing pressing machine comprises forcing press body and reference column 15, fixed stop 16, cylinder control button 8, cylinder control valve 3.The pressure head 1 of the downward activity that links to each other with the forcing press cylinder piston rod, aim at installation with wedge 2 central axis on being installed in workpiece placement workbench, 2 workpiece reference columns 15 and 1 workpiece fixed stop 16 are installed on the workbench 6 of place work piece on the forcing press body.Substitute artificial hand with moving downward equably of the piston rod of air-operated control and play hammering, pressure can be regulated control accurately, guarantees that the oil sealing each several part is stressed evenly, good sealing is arranged, no longer leakage of oil.

The stage casing of pressure head 1 has the tubular body of screw in the middle of being, on have the hexagon pressure head hold-down nut 14 and the columniform piston rod 9 of the below of forcing press cylinder to be connected to a fixed.The centre has the lower end of the tubular body of screw to be connected with the working end of pressure head bottom with screw thread.It is bigger that the stage casing is compared in the endoporus aperture of working end, pressure head bottom.Support column 4, the perpendicularity of the processing of each part parts of cylinder supports plate 7 and pressing machine integral body and assembling common guarantee piston rod, the relative table surface of pressure head.

Wedge 2 central axis are aimed at pressure head 1 location, are fixed on the platen of forcing press body workbench 6.The outside dimension of wedge 2 has less clearance to cooperate with chain guard oil seal seat bottom position.

2 cylindrical work reference columns were listed in a side of wedge 2 in 15 minutes, were fixedly mounted on the platen of forcing press body workbench.Away from wedge 2, vertical fixing is installed on the platen of forcing press body workbench the workpiece fixed stop 16 of strip at the homonymy of wedge 2 and reference column 15.The accurate location of workpiece when reference column and fixed stop common guarantee timing chain guard oil sealing press-fit.

Wedge 2 centers are provided with the passage of a Φ 5, and purpose is the resistance that press-fits in order to reduce.

Timing chain guard oil sealing pressing machine, the control stick of cylinder control valve 3 is installed in the relative operator's of pressing machine body a side, cylinder control button 8 is contained in the opposite side of pressing machine body, and cylinder control valve and control button gas circuit are in series in control loop, for the another hand operated.To guarantee to have in two hands one can not start equipment, avoid personal injury in pressure head following time.

Adopt above-mentioned accurate location and special-purpose press-loading apparatus, overcome fault and defective that all manual operationss in the past produce by facts have proved timing chain guard oil sealing pressing machine of the present utility model, beneficial effect is:

1. improve effect 300%, greatly reduce labour intensity, saved a large amount of labor hours, make oil sealing more smoothly light when mounted;

2. accurately installed when oil sealing is on being installed to the timing chain guard, do not have inclination, cut edge or be pressed into defectives such as shallow, dark excessively, eliminated engine and the seepage fault in operation process, occurred leaking.Accomplish that workpiece reaches 100% certified products.
