According to the disassembling method for the large gantry milling sliding seat, the influence of external force of hoisting and the like on structural precision of a machine tool in the disassembling process is lowered while high efficiency, low cost and reduction of labor intensity of workers are guaranteed.
Description
Technical field
The present invention relates to large-sized gantry milling maintenance of equipment dismounting technical field, be specifically related to the method for dismounting of large-sized gantry milling slide.
Background technology
When large-sized gantry milling slide or guide rail maintenance, slide need to be dismantled and keep in repair, traditional dismounting process program
Being to use first to tear crossbeam open, after having torn crossbeam open, column removes again, finally could take out slide from guide rail.This traditional process program needs to remove the hydraulic system on crossbeam during tearing crossbeam open successively, electric system, main shaft, crossbeam, column and slide, dismounting processing step is many and complicated, construction is time-consuming long, several workmen is needed to complete, efficiency is low, cost is high, and later stage installation needs to install whole gantry mill, installation process needs to crossbeam, the structural members such as column carry out accuracy resumption, owing to early stage unloading process is to crossbeam, column, the large-sized structural parts lifting actions such as slide are bigger, heavy parts rigidity is caused to deform, later stage is often difficult to crossbeam, column, slides etc. return to original original geometry precision.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of large-sized gantry milling slide method for dismounting, gantry mill slide is dismantled in the case of not dismantling gantry mill miscellaneous part by it, reduce workload, improve efficiency, reduce cost, reduce the lifting action to large-sized structural parts such as machine tool beam, column, slides simultaneously, reduce the external force that large parts is suffered in whole unloading process, reduce the precision impact that rigidity deformation causes.
The present invention solves above-mentioned technical problem the technical scheme is that large-sized gantry milling slide method for dismounting, comprise the following steps:
S1, disconnect the static pressure oil circuit joint between end floor beam to be torn open and column, between column and slide and terminal, remove the static pressure worm box on slide to be torn open, covering, and other appurtenances;
S2, lay down the connecting bolt waiting to tear open between end column and slide, beam force deformation when the connecting bolt between pine other end crossbeam and column is to prevent dismounting;
S3, square chest of purchasing, two set hydraulic jack, two set mechanic jacks, and some square cushion blocks, two set hydraulic jack are peaked at end floor beam muscle portion to be torn open, square cushion block is padded between hydraulic jack and crossbeam, and waits to tear end open to some pieces of amesdials of other end spaced set from it on crossbeam;
S4, use two set hydraulic jack jack-up wait to tear end column and crossbeam open, make to wait to tear end column open and slide disengages proper height, and during jack-up, on guarantee crossbeam, the reading variable quantity of each amesdial arranges order even variation in direct ratio by it;
S5, wait tearing end column open and slide disengages after proper height, use two set mechanic jacks auxiliary to hold crossbeam to prevent hydraulic jack to lose efficacy;
S6, the static-pressure oil chamber of the guide rail of slide to be torn open is passed through gases at high pressure, makes slide to be torn open float, then use the jack will be below slide be torn open hauling-out column.
Beneficial effect: the present invention, in unloading process, does not remove the hydraulic circuit on crossbeam, column, slide, circuit, is only to disconnect the static pressure oil circuit joint between crossbeam and column, between column and slide and terminal;And only lay down and wait to tear open end slide and the connecting bolt of column, do not shed the bolt of other junctions, therefore, the present invention dismantles that parts are few, labor intensity is low, and the later stage recovers to install easily.
In unloading process, the jacking speed in each portion of crossbeam is monitored in the reading change by the some amesdials arranged on crossbeam, and then controls the jacking speed of hydraulic jack, it is to avoid unloading process middle cross beam deforms.
Gases at high pressure are utilized to wait to tear open formation static air film between end slide and guide rail, reduce the frictional force between slide and guide rail, and tearing end slide open hauls out below column to use jack to wait, prevent slide and guide rail contacting surface to be scratched the generation of situation, just slide can be hauled out by less external force simultaneously.
The dismounting technique of the present invention, ensureing efficiently, while low cost, reduction labor strength, reduces the impact on machine tool structure precision of the external force such as lifting, makes lathe maintain original geometric accuracy in whole unloading process.
