Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.As shown in Figure 1 and Figure 4, the invention discloses a kind of bearing press mounting dismounting machine, comprise overall gantry frame 1, the main composite oil cylinder 2 in left and right and guider 6, wheel is to lowering or hoisting gear 9, locking device 11, push boat device 10, bearing spider 7, bearing rotary device 12, hydraulic system, measure and electric control system, the main composite oil cylinder axial symmetry in left and right is loaded in the support of gantry type frame left and right, the large piston rod front end of the main composite oil cylinder in described left and right is equipped with to move back and is unloaded pulling claw device 5, described moving back unloads pulling claw device by hydraulic motor 51, arm-tie 52, pulling block 53 forms, described hydraulic motor is contained in below arm-tie, pulling block is contained in above arm-tie.Move back when unloading bearing, rotated by fluid motor-driven pulling claw device, arm-tie 52 fastens bearing bonnet, and large piston rod unloads pulling claw device retreat with moving back, bearing of backing off.
Described bearing rotary device is made up of motor, casing, cylinder, main shaft, runner, and it is arranged on main composite oil cylinder guider, described casing is equipped with cylinder, is provided with main shaft in casing, and runner is equipped with in main shaft one end, and the other end and motor section are divided and be connected.It is arranged on main composite oil cylinder guider, moves together with ram piston.In pressing bearing process, drive driven by rotating wheel bearing to rotate by motor, ensure that bearing axis is concentric mutually with piston centreline, conveniently press-fit, ensure that Bearing inner structure is not damaged, improve bearing press mounting quality.
Described overall gantry frame forms gantry frame by base, left and right support and entablature, carry out integral solder, carry out whole removing stress annealing, Digit Control Machine Tool carries out overall processing, and adopt finite element analysis, guarantee that there is enough Rigidity and strengths, good damping property and lasting stability.
Described wheel comprises workbench, guide rail, elevating ram to lowering or hoisting gear, and have two elevating rams to be fixed on base, its oil cylinder end is connected with workbench bottom surface, and on workbench, Plane Installation has two wheel rails.
Left and right of the present invention main composite oil cylinder structure is identical, and adopt inside and outside two-layer composite oil cylinder structure, two-layer oil cylinder can independently work.The main composite oil cylinder in left and right can work independently or works simultaneously, is completed by electrichydraulic control.In bearing press mounting process, small piston rod end is provided with Finial device, and clamp after can carrying out centre bore location to wheel shaft, ensure that two oil cylinder centers are concentric to axle centerline with wheel, large pistons end has installed pressure head, for pressing bearing inner ring.Locate the centre bore of different axletree, only needs were changed top in 30 seconds.
In order to adapt to press-fiting of the wheel set bearing of different gauge and different axle length, the left and right of equipment is main to be press-fited combined oil cylinder and is designed to along piston axis direction adjustable.
