The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.Like Fig. 1 and shown in Figure 4; The utility model discloses a kind of bearing press, comprise whole gantry type frame 1, about mainly press-fit composite oil cylinder 2 and pressure head guider 3, wheel is formed lowering or hoisting gear 4, locking device 5, push boat device, bearing spider, hydraulic system, measurement and electric control system, about mainly press-fit the composite oil cylinder axial symmetry and be loaded in the support of the gantry type frame left and right sides; The described main composite oil cylinder of pressing adopts two cylinder structures; One end of its cylinder sleeve 21 is equipped with bottom 22, and big piston 23 in the cylinder sleeve is equipped with inner cylinder liner 24 in the big piston; Valve piston 25 is housed in the inner cylinder liner; Top body 27 and top 28 is housed before the pre-installed pressure head of big piston 26, the valve piston, and wherein cylinder sleeve and big piston are outer oil cylinder, and inner cylinder liner and valve piston are the internal layer oil cylinder; Described locking device comprises locking head 51, slide block 52, voussoir 54, locking cylinder 53, is fixed on the base of one of gantry type frame, is provided with voussoir before the piston rod of its locking cylinder, and voussoir passes in the middle of slide block, and slip front is equipped with locking head.
Described whole gantry type frame is the welded unit that on base 11, is provided with left and right sides support (12,13) and entablature 14 compositions.
The described wheel comprises workbench 41, guide rail 42, elevating ram 43 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.
It is main about the utility model that to press-fit the composite oil cylinder structure identical, two-layer composite oil cylinder structure inside and outside the employing, and two-layer oil cylinder can work alone respectively.In the bearing press mounting process, the small piston rod end is equipped with Finial device, can carry out back, centre bore location to wheel shaft and clamp, and the two oil cylinder centers that guarantee are concentric to axle centerline with wheel, and pressure head has been installed in the big piston end, 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 adjust along the piston axis direction.
On the master cylinder seat of the left and right sides, laser sensor is installed, is used with base-mounted displacement.When upper mounting plate rises, laser sensor inspection vehicle axle bearing position place Up Highway UHW, it is high to the center to measure wheel, sends instruction to the displacement transducer of up-down upper mounting plate, makes upper mounting plate be parked in assigned address.
The utility model adopts wheel to lowering or hoisting gear, locking device, push boat device; The wheel of treating pressing bearing is to getting on the integral elevating apparatus platform through train track; And guarantee its axle centerline with about to press-fit the oil cylinder center line mutually concentric; Locking device through being installed in both sides on the upper mounting plate is the locking of wheel inner face, makes wheel to play not when the pressing bearing.After bearings at both ends had press-fited, wheel unclamped locking device, and the push boat device that is installed in the upper mounting plate upper rail will be taken turns releasing the operating position, smoothly access arrangement track opposite side.Because wheel is to being to drop on the whole support system; Has no relation with the right complexity of wheel; The equipment that both guaranteed carries out bearing press mounting easily, can guarantee that again wheel press-fits the concentricity of oil cylinder center line to axle centerline and two ends through the measurement mechanism of support system.
Measurement mechanism is installed on the base; Displacement transducer is installed on it, and the movable head and the upper mounting plate of displacement transducer link, thereby measure the displacement of upper mounting plate; The motion of control motor guarantees that wheel press-fits the concentricity of oil cylinder center line to axle centerline and two ends.
It is taken turns locking device is made up of locking head, slide, voussoir, locking cylinder etc.Its operation principle: locking cylinder, slide are fixed on the base, and voussoir links to each other with the locking cylinder end, treat that two main compressing cylinders are top to taking turns after the clamping of location; Promote voussoir by locking cylinder; Slide block is moved, will take turns external side end face through locking head and clamp, form pincerlike the clamping with inboard block; Prevent to press-fit in the process wheel to about string moving, and pressure well passed to whole frame through slide.
Its push boat mechanism is made up of two cover push boat cylinder apparatus, and every cover push boat cylinder apparatus is made up of oil cylinder, push boat piece, bearing pin etc.Its operation principle is: all have the rectangle hole on the following dull and stereotyped two wheel guide rails; Two cover push boat cylinder apparatus are installed respectively in the rectangle hole on the left and right rail through bearing pin; After bearing press mounting is intact, push boat oil cylinder pulling push boat piece one end, the push boat piece other end acts on the tread of wheel do circular motion; Thereby take turns on the track that pushes the equipment other end whole, the process of whole wheelset fitting bearing is accomplished.
Bearing bracket holds up institute's pressing bearing, and bearing is rotated last, guarantees that bearing axis is mutually concentric with the ` plug center line of living, and conveniently press-fits.
Mainly about hydraulic system is mainly given press-fit composite oil cylinder, wheel and to push boat organization cylinder etc. power is provided retaining mechanism oil cylinder, wheel.
This machine adopts a cover hydraulic system, and hydraulic system is made up of fuel tank, Oil pump electrical machinery, oil pump, integrated package, hydraulic valve, pressure sensor, Pressure gauge, filter, pipeline etc., and all hydraulic components and parts all are contained on the fuel tank, link through oil pipe and each oil cylinder.
