Description
Technical field
The present invention relates to for goods train vehicle RD2, RE2B type wheel shaft rolling bearing pressing and move back the technical field of unloading, specifically belong to railway vehicle wheel to rolling bearing pressing, move back and unload all-in-one.
Background technology
For guaranteeing the safety of railway transportation, press-fiting and moving back the process of unloading of rolling stock rolling bearing has strict requirement.Rolling stock rolling bearing pressing and moving back unloaded in the past is all overhaul section by specialty to carry out, and all has special equipment.Along with the reinforcement of business administration, the maintenance that all multiple enterprises provide rolling stock for oneself has been come by oneself, this type of small lot goods train vehicle wheel shaft rolling bearing pressing and move back the cost burden unloading special equipment and greatly add large enterprises.Railway vehicle wheel to rolling bearing pressing move back unload all-in-one design, making, solve private car well with the rolling bearing pressing of RD2, RE2B type wheel shaft with move back the work of unloading.
Summary of the invention
The object of this invention is to provide a kind of railway vehicle wheel to move back rolling bearing pressing and unload all-in-one, operating efficiency is high, mechanical structure is reasonable, three composite oil cylinder structures ensure that axletree is not impaired in bearing press mounting process, trying hard to keep in the top pre-set constant top of valve piston, card is accurate locates, the prestressing force of middle piston and the rotary structure of position nose ensure that axle shaft end plane contact, the maximum feature of this oil cylinder is that piston is capable of expansion and contraction when dry running, bearing moves back and unloads structural design, the removal force of bearing is born by dismantling oil cylinder, be not delivered to lathe bed, serviceability is reliable, easy and simple to handle.
Technical scheme of the present invention is as follows:
Railway vehicle wheel moves back rolling bearing pressing and unloads all-in-one, include lathe bed, lathe bed is furnished with successively bearing and moves back handler, V-arrangement axle bracket, wheel shaft lift rotating equipment, bearing press-fitting device, displacement detector, described bearing retreatment device includes and is fixed on moving back of lathe bed and unloads cylinder slide, move back to unload on cylinder slide and be installed with propelling cylinder, retreatment oil cylinder, bearing receiving device, the piston rod of propelling cylinder is connected with dismounting oil cylinder, the piston rod of dismounting oil cylinder is hinged with retreatment pawl, retreatment pawl side-lower is hinged with pulling claw cylinder, move back and unload pawl automatic wrapping rolling bearing backstop seal receptacle, hook bearing demolition backstop seal receptacle end face, the piston rod overhead of retreatment oil cylinder is in axle end face, described wheel shaft lift rotating equipment includes the hoist cylinder rotating and be arranged on lathe bed, described bearing press-fitting device includes hub support seat, the bearing bracket be fixed on lathe bed, press-fits cylinder seat, press-fit cylinder seat is installed with and press-fit hydraulic cylinder, press-fit between the piston rod of hydraulic cylinder and cylinder body end face and be provided with fairlead, and the end face of piston rod is provided with gland.
Described retreatment pawl is L-shaped.
Described press-fiting in hydraulic cylinder is provided with Pressure gauge, hydrostatic sensor.
The dual-use formula that the present invention adopts, can, according to different workpieces and different process requirement, select different technical parameters and frock complete the rolling bearing pressing of different types railway wagon wheel shaft and move back the work of unloading.Press-fit, have in unloading process and automatically hold out against axletree, automatically measure the function such as displacement, record pressure curve press-fiting in process.Pressure of the present invention moves back machine bearing press-loading apparatus, meets the Ministry of Railways and requires automatically to record displacement---the rolling bearing pressing machine of new generation of pressure relationship plot and relevant data produced in rolling stock rolling bearing pressing process.It is the special equipment of rolling stock rolling bearing pressing, dismounting.
The present invention at railway vehicle wheel to rolling bearing pressing, move back in the process of unloading, the Ministry of Railways must be met and rolling bearing is moved back unload and axis of rolling pressing machine related request, add wheel shaft lift rotating equipment, hub support seat.Wheel shaft lift rotating equipment is used for wheel to unload the bearing press mounting or move back revolving turnback after rising and complete other one end.Hub support seat is used for the positioning action in bearing press mounting process.Thus the functional requirement of two equipment is completed with an equipment.
