Specific embodiment
Below in conjunction with attached drawing, the present invention will be further described.
As shown in Figures 1 to 6, a kind of fixed bearing press mounting dismounting machine, including chassis 1, retainer trolley 2, hydraulic system,
Electric-control system, left head is equipped with fixed beam 3 on the chassis 1, and right head is equipped with after-poppet 4, sets between fixed beam and after-poppet
There are two pull rods (5,6) up and down, open-work 61 is correspondingly provided on two pull rods, the fixed beam intermediate lateral is equipped with master cylinder 31, institute
It states and is equipped with walking beam A7 and walking beam B8 between fixed beam and after-poppet, walking beam has electric walking mechanism 71, walking beam
Correspond to pull rod open-work up and down and be equipped with locked cylinder 72, is transversely provided with master cylinder 31 on walking beam A and after-poppet, two master cylinders are same
Axis, walking beam B are equipped with activity support shaft device 81.
Finial device 311 is equipped with before the master cylinder.
The chassis is equipped with two movements and lifts trolley 2.
Two master cylinder of the machine is composite oil cylinder structure, be pressed, move back unload low floor vehicle bearing when, center piston boom end
Finial device positions axle by centre bore, guarantees press fitting, moves back the overall process axle centerline unloaded and two master cylinder center lines
With one heart.Wherein a set of master cylinder is mounted in fixed beam, another master cylinder is mounted on walking beam A and after-poppet.
Two sets of walking beams are all made of electronic movement, and oil cylinder latch structure is locked on two pull rods, wherein in a set of walking beam A
Master cylinder is installed, the press fitting of low floor vehicle bearing is participated in, moves back and unload；Another set of walking beam participates in the press fitting of single track framework, moves back and unload,
It also assists in moving back for low floor vehicle bearing to unload, is provided with activity support shaft device at left and right sides of set walking beam, which can be on front and back
