Description
Technical field
The present invention relates to a kind of vertical lathe spindle to install and method for dismounting, belong to Machining Technology field.
Background technology
At present, machine industry vertical lathe spindle is installed and is adopted hammering method to install.Namely use large copper rod by two workmans, symmetry is knocked and is installed on table base by main shaft.Like this, not only bring huge physical demands to workman, but also element precision may be caused to wander away, can not use.And once find loss of significance, can not use, want main shaft to disassemble, just more difficult.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of vertical lathe spindle to install and method for dismounting, by using hydraulic jack to mount and dismount main shaft, ensure feasibility and the reliability of main shaft installation accuracy and dismounting.
The technical solution adopted for the present invention to solve the technical problems is: vertical lathe spindle is installed and method for dismounting, carrys out vertical lathe spindle install and dismounting by using the stroke of auxiliary element and hydraulic jack; Described auxiliary element comprises: pallet, large top cover, large high nut, large stud, little high nut, little top cover, little stud.
Main shaft installation method:
1. above centre bore main shaft overhead traveling crane being suspended in table base;
2. be connected with four screwed holes of table base through four holes of main shaft with four large studs;
3. with overhead traveling crane, main shaft is steadily fallen into centre bore, load pallet in main shaft upper end;
4. hydraulic jack is placed on pallet;
5. four of large top cover holes are steadily placed in hydraulic jack through large stud, and lock with large high nut;
6. start hydraulic jack by the centre bore of the bottom surface spindle nose press-in table base of main shaft, until the upper plane of the bottom surface of main shaft and table base does not enter with 0.04 clearance gauge.
Main shaft method for dismounting:
1. screwed in the screwed hole of table base by the hole on main shaft by four large studs, its upper end is screwed into large high nut;
2. larger top cover is fallen into large stud, regulate large high nut to make large top cover steady;
3. by little stud through the hole of large top cover be screwed into main shaft upper end screwed hole in;
4. hydraulic jack is placed on large top cover;
5. little top cover is placed in hydraulic jack through little stud, screws on little high nut;
6. start hydraulic jack, the centre bore of main shaft from table base is pulled out.
The invention has the beneficial effects as follows: utilize hydraulic jack to mount and dismount main shaft.Like this, not only reduce the labour intensity of operator, and well ensure that the precision after Assembly of the parts, also solve a difficult problem for main shaft dismounting difficulty simultaneously.The method is simple and reliable, workable, and assembly precision is high.
