The specific embodiment
The present invention is further described below in conjunction with accompanying drawing.As shown in Figure 1 and Figure 4, the invention discloses a kind of bearing press mounting dismounting machine, comprise whole gantry frame 1, about main composite oil cylinder 2 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, about main press-fit the composite oil cylinder axial symmetry and be loaded in the support of the gantry type frame left and right sides, the large piston rod front end of main composite oil cylinder is equipped with to move back and unloads pulling claw device 5 about described, described moving back unloaded the pulling claw device by hydraulic motor 51, arm-tie 52, pulling block 53 forms, described hydraulic motor be contained in arm-tie below, pulling block be contained in arm-tie above.Move back when unloading bearing, by fluid motor-driven pulling claw device rotation, arm-tie 52 fastens the bearing bonnet, and large piston rod unloads the pulling claw device and retreats the bearing of backing off with moving back.
Described bearing rotary device is comprised of motor, casing, cylinder, main shaft, runner, and it is installed on the main composite oil cylinder guider, on the described casing cylinder is housed, and is provided with main shaft in the casing, and main shaft one end is equipped with runner, and the other end and motor partly link.It is installed on the main composite oil cylinder guider, moves with the pressure head piston.In the pressing bearing process, be rotated by motor-driven driven by rotating wheel bearing, guarantee that bearing axis is mutually concentric with the piston center line, conveniently press-fit, guarantee that the bearing internal structure is not damaged, and has improved the bearing press mounting quality.
Described whole gantry frame forms gantry frame by base, left and right sides support and entablature, carry out integral solder, carry out the whole removing stress annealing, carry out integral body processing at Digit Control Machine Tool, and employing finite element analysis, guarantee to have enough Rigidity and strengths, good damping property and lasting stability.
The described wheel comprises workbench, guide rail, elevating ram to lowering or hoisting gear, has two elevating rams to be fixed on the base, and its oil cylinder end links to each other with the workbench bottom surface, and Plane Installation has two wheel rails on the workbench.
Main about the present invention to press-fit the composite oil cylinder structure identical, adopts inside and outside two-layer composite oil cylinder structure, and two-layer oil cylinder can work alone respectively.About main press-fit composite oil cylinder and can work independently or work simultaneously, finished by electrichydraulic control.In the bearing press mounting process, the small piston rod end is equipped with Finial device, can carry out clamping behind the centre bore location to wheel shaft, and the two oil cylinder centers that guarantee are concentric to axle centerline with wheel, and large pistons end has been installed pressure head, is used for the pressing bearing inner ring.To the centre bore location of different axletrees, only need in 30 seconds, change top getting final product.
For press-fiting of the wheel set bearing that adapts to different gauges and different axle length, mainly about equipment press-fit combined oil cylinder and be designed to along piston axis direction capable of regulating.
The master cylinder seat is equipped with laser sensor in the left and right sides, is used in conjunction with base-mounted displacement.When upper mounting plate rose, laser sensor inspection vehicle axle bearing position place Up Highway UHW was measured wheel high to the center, sent instruction to the displacement transducer of lifting upper mounting plate, made upper mounting plate be parked in assigned address.
