The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.Extremely shown in Figure 7 as Fig. 1, the utility model discloses a kind of wheel disc axle box press-fits, dismounting machine, comprise built-in beam device 1, walking beam device 2, support 3, pillar 4, base 5, follow-up material-supporting holder device 6, master cylinder device 7, hydraulic system, electric-control system, checkout gear, described built-in beam device 1 is fixed on the base 4, and connect and compose a stress frame with walking beam device 2 and 4 assemblings of two lateral struts, two pillars of support 3 supportings are fixed on the other end of base 5, in the described built-in beam device 1 master cylinder device 7 is housed, described master cylinder device piston rod front end is equipped with moving column device 8, can install extension arm additional on the parallel fork 9 of piston rod front end, extension arm adds when press-fiting brake disc and installs, press-fit wheel to the time then do not adorn, holder shaft device 10 is equipped with in its piston rod front lower place, have the chute that moves forward and backward for slide body on the described walking beam device right side, slide body is equipped with oil cylinder up and down, can install the little tiger iron of different inner diameters on the slide body U type opening additional, linear guides is installed on base, and the driving oil cylinder is installed, driving the piston rod of oil cylinder and the bottom of walking beam body links, for convenience various the wheel right press-fit and dismantles, the U type open side of walking beam and after-poppet is opened, its U type opening size is according to satisfying various wheelset fittings, the back-pressure test, dismounting requires comprehensively to determine to be designed to φ 1020mm, so that gear can pass through in opening.The right side of walking beam has been designed chute up and down and has been moved forward and backward for slide body.Its slide body moves forward and backward by hydraulic oil cylinder driving, can install the little tiger iron of different inner diameters on the slide body U type opening additional, by the combination of these different-diameter tiger iron, realizes that various the wheel test the press-fiting of wheel, gear, brake disc, axle box, dismounting and the right back-pressure of locomotive wheel.On the described walking beam device dowel mechanism is housed, described two column sections are rectangle, equidistantly on the Body of pillar are provided with round locating hole 41, match with alignment pin on the walking beam.When walking beam moved on to certain working position, the circular locating hole chucking that the effect of the alignment pin on it by oil cylinder enters on the Body of pillar was realized the location.
Described moving column device 8 is to be made of with piston rod coaxial line cylinder 82 oil cylinder 81 connections one perpendicular to piston rod.
Described holder shaft device 10 is that a follow-up material-supporting holder device 6 is housed on one I-shaped 101.This is in order to guarantee to take turns to decomposing and the overlapping of balance during the back-pressure test and axle centerline and oil cylinder piston bar center line, reduce crane gear (overhead traveling crane) holding time, it can not dismantle or withdraw from during the back-pressure test station again along the servo-actuated of main oil cylinder piston rod axis.The to be removed wheel on the holder shaft device and retainer support that are placed on the walking beam left and right sides in the right decomposition unloading process of wheel, is unlikely to pull wheel shaft, wheel or brake disc like this.
Described dowel mechanism is before oil cylinder, oil cylinder are housed on cylinder support hard garden post alignment pin to be housed.
Displacement transducer is equipped with on the cylinder apparatus limit, and the oil cylinder inner carrier is by oil pressure actuated, and the distance that piston moves is detected by displacement transducer, and can show on industrial computer.The work of piston and the extreme position of backhaul are controlled by two travel switches.Described follow-up material-supporting holder device 6 has two to overlap on the base 5 that is installed between built-in beam and the walking beam, and described master cylinder device is provided with guiding mechanism.
Described follow-up material-supporting holder device is under stake body travelling wheel to be housed, and V-block is housed on it, and manual lead screw-lift nut device is contained under the V-block.Wheel is to being supported on the two cover follow-up material-supporting support V-blocks, and before press-fiting beginning, it is mutually concentric with main oil pressuring cylinder piston bar center line to proofread and correct axle centerline, when press-fiting, two cover follow-up material-supporting supports with wheel to the moving and servo-actuated of axletree, conveniently, laborsaving.
As shown in Figure 6, when press-fiting right wheel, to take turns hanging on the follow-up material-supporting holder device by the 500kg electric single-beam crane that is placed on built-in beam (press-fiting, dismantle the lifting of hour wheel to adapt to), transition axis or cover, U type tiger iron etc., walking beam moves on to left head, and corresponding tiger iron is housed in it, can withstand the left end of axletree, and after wheel enters the axletree right-hand member, moving column device leaves center line, promotes wheel hub by the parallel fork before the oil cylinder, and the press mounting of car wheel is put in place.
As shown in Figure 7, do not adorn tiger iron in the walking beam, axletree can be passed, and moving column device moves to the oil cylinder front end and withstands the axletree right-hand member, after wheel entered the axletree right-hand member, oil cylinder advanced and offsets and be press-fit into place until right wheel and walking beam.
Press-fiting precision is controlled by checkout gear.
Move back to unload and then be and press-fit opposite operating process, only need the position of mobile walking beam and retainer support, make walking beam block wheel, the oil cylinder promotion axletree that advances, then wheel moves back and unloads down; Then can back off another wheel or brake disc etc. of tune in like manner.
Wheel has brake disc to the centre then can be realized by installing extension arm additional.
The wheel that has cabinet as the centre is finished the mode that then can adopt tune to press-fit.
