The valve port of dress cylinder is slidably connected；Valve guide bushing is set in the top of elastic guide rod assembly, when press-fiting under oil cylinder band dynamic head
During pressure, pressing valve guide bushing under pressure head, elastic guide rod assembly shrinks thus is imported by valve guide bushing in the valve port of cylinder to be press-fited.
Actual pressure size can be passed to controller by pressure transducer, when pressure is shut down beyond prescribed limit alarm, keeps away
Exempt from pine or the tension phenomenon excessively produced because valve guide bushing fit tolerance is improper.
Described elastic guide rod assembly includes valve guide post, compression spring and the elastic force regulation spiral shell set gradually from top to bottom
Nail, described valve guide post is slidably connected with the valve port of cylinder to be press-fited, and the top of valve guide post is extended and waited to press-fit
The valve port of cylinder, valve guide bushing is set in the top of guide post.
The middle part of support frame as described above is provided with oil-free fairlead, described in press-fit guide post and be slidably connected with oil-free fairlead.
The stroke inductive switch of push rod stroke before control press-fits oil cylinder it is provided with at oil cylinder back guide bar press-fiting.
Described pressure conduit frock is fixed on the upper surface of base by position adjustments plate.
The present invention uses above technical scheme, has the advantages that the pressing machine of the present invention can guarantee that valve guide bushing
It is pressed in the valve port of cylinder quickly and smoothly under the effect of elastic guide rod assembly, and can guarantee that the pressure model in regulation
In enclosing, when pressure is shut down beyond prescribed limit alarm, it is to avoid produce because valve guide bushing fit tolerance is improper cross pine or
Person's tension phenomenon.It addition, the pressing machine of the present invention just can press-fit 2 valve guide bushings in the most every 8 seconds, press-fit efficiency and significantly carried
High.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details:
Fig. 1 is the schematic diagram of the present invention a kind of cylinder valve conduit pressing machine；
Fig. 2 is the schematic diagram of pressure conduit frock.
Detailed description of the invention
As shown in Figure 1 or 2, the present invention includes that base 1, base 1 are provided with pressure conduit frock 2, and cylinder 3 to be press-fited is fixed
Position, in pressure conduit frock 2, base 1 is additionally provided with bracing frame 4, the top of bracing frame 4 and being arranged in pressure conduit frock 2
Press-fiting oil cylinder 5, the front push rod press-fiting oil cylinder 5 is arranged down；Press-fit and be connected with in turn from top to bottom on the front push rod end of oil cylinder 5
Coupling bar 6, pressure transducer 7, press-fit guide post 8 and pressure head 9；Pressure conduit frock 2 includes base plate 21 and positioning seat 22, positioning seat
22 are fixed on base plate 21 upper surface, and the top of positioning seat 22 is provided with and the projection of cylinder holes location fit of cylinder to be press-fited 3, location
Being provided with elastic guide rod assembly at the valve port of corresponding cylinder 3 to be press-fited in seat 22, location is extended in the upper end of elastic guide rod assembly
Seat 22 valve port with cylinder 3 to be press-fited are slidably connected；Valve guide bushing 12 is set in the top of elastic guide rod assembly, when press-fiting
When oil cylinder 5 band dynamic head is pressed for 9 times, 9 times pressure valve guide bushings 12 of pressure head, elastic guide rod assembly shrinks thus is imported by valve guide bushing 12
In the valve port of cylinder 3 to be press-fited.
Elastic guide rod assembly includes valve guide post 23, compression spring 24 and the elastic force regulation spiral shell set gradually from top to bottom
Nail 25, valve guide post 23 is slidably connected with the valve port of cylinder 3 to be press-fited, and the top of valve guide post 23 is extended and waited to press
