Description
Technical field
The present invention relates to water pump seal of automobile to install equipment technical field, more particularly to a kind of engine cooling water pump reclaimed water
Device and assembly method are matched somebody with somebody in encapsulation.
Background technology
The widely used centrifugal water pump of automobile engine, its basic structure is by water pump body, bearing, water seal, impeller, belt pulley
Formed Deng parts.It is different according to bearing arrangement, axle can be divided into and link structure water pump and isolating construction water pump.Axle links structure water pump
Using the water pump of shaft connecting bearing.Traditional assembly method is：Water seal is arranged on water seal pressure head；The pump housing is face-up greatly, installation axle
The water pump component held is so that the big end of bearing is cylindrical and pump housing small end face positions, and pressing plate compresses the big face of the pump housing, and then plunger tip holds out against bearing
Big end end face is simultaneously locked, and last pressure head is depressed into drawing requirement position.Being pressed its drawback in this way has at following 3 points：1）Water
Pump housing majority is irregular shape, weighting situation be present, bearing centre produces skew after the pump housing is placed；2）It is cylindrical with the big end of bearing
Due to there is fit clearance in positioning, after the pump housing is put into, the small end of bearing produces skew, and bias is produced when water seal is pressed.3）It is above-mentioned
Pressing method at least needs two people's operations, and operation is wasted time and energy, and efficiency of assembling is extremely low, and two people one day are only capable of installing for 8 hours
20, what is more important yield rate is low, yield rate only 60%.And pump housing weight is not easy to grasp balance greatly, easily smashes bearing
Or/water seal, and impulsive force is big during pounding, and produces reaction force, easily causes water seal damage.CN201220597778.1
A kind of shaft connecting bearing water seal pressing machine, including frame, press fitting main part, oil cylinder, electric control box, hydraulic station, are pressed main body
Part includes：Bottom plate；Lead；Water seal positions support base, on bottom plate, for supporting water seal；Upper fixture installing plate, position
Above bottom plate, and there is through hole, be connected by being arranged in the linear bearing among through hole with lead, upper fixture installing plate can
Moved along lead；Upper fixture, for clamping shaft connecting bearing；Float plate, between bottom plate and upper fixture installing plate, float plate
It can be moved along lead；Float plate is provided with jig plate in the position that support base is positioned relative to water seal, for clamping the pump housing, fixture
The position for positioning support base on plate and float plate relative to water seal is provided with through hole, and during float plate decline, water seal may pass through
Through hole.Press fitting efficiency of the present utility model increases, and water seal position inaccurate, easily damages water pump and bearing by pressure.
The content of the invention
The problem of existing the present invention be directed to above-mentioned prior art, there is provided a kind of engine cooling water pump reclaimed water encapsulation is equipped
