Abstract
The invention discloses methods for installing and detaching a main shaft of a vertical lathe. The main shaft of the vertical lathe is installed and detached by using the strokes of an auxiliary element and a hydraulic jack. The installation method comprises the following steps of: 1, hoisting the main shaft above the central hole of a base; 2, connecting a large threaded stud with the threaded hole of the base by penetrating through the hole of the main shaft; 3, placing a tray into the upper end of the main shaft; 4, placing the hydraulic jack on the tray; 5, placing a large top cover on the hydraulic jack, and locking with a large thick nut; and 6, starting the hydraulic jack to press the bottom surface shaft head of the main shaft into the central hole of the base. The detaching method comprises the following steps of: 1, screwing the large threaded stud into the threaded hole of the base through the hole in the main shaft, and screwing the upper end of the large threaded stud into the large thick nut; 2, making the large top cover drop into the large threaded stud; 3, screwing a small threaded stud into a threaded hole in the upper end of the main shaft by penetrating through the hole of the large top cover; 4, placing the hydraulic jack on the large top cover; 5, placing a small top cover on the hydraulic jack, and screwing a small thick nut; and 6, starting the hydraulic jack to pull the main shaft out of the central hole of a workbench base.
Description
Technical field
The present invention relates to a kind of vertical lathe spindle and install and method for dismounting, belong to the Machining Technology field.
Background technology
At present, the 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 main shaft is installed on the table base.Like this, not only brought huge physical demands to the workman, but also may cause element precision to be wandered away, can not use.In a single day and find loss of significance, and can not use, want main shaft is disassembled, just more difficult.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of vertical lathe spindle to install and method for dismounting, mount and dismount main shaft by using hydraulic jack, guarantee 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, comes vertical lathe spindle to install and dismounting by the stroke with 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.
The main shaft installation method:
1. be suspended in main shaft above the centre bore of table base with overhead traveling crane;
2. four holes passing main shaft with four large studs are connected with four screwed holes of table base;
3. with overhead traveling crane main shaft is steadily fallen into centre bore, the pallet of packing in the main shaft upper end;
4. hydraulic jack is placed on the pallet;
5. large stud is passed in four holes of large top cover and steadily place on the hydraulic jack, and lock with large high nut;
6. start hydraulic jack the bottom surface spindle nose of main shaft is pressed into the centre bore of table base, until the upper plane of the bottom surface of main shaft and table base does not enter with 0.04 clearance gauge.
The main shaft method for dismounting:
1. four large studs are screwed in by the hole on the main shaft in the screwed hole of table base, its upper end is screwed into large high nut;
2. larger top cover is fallen into large stud, regulate large high nut and make large top cover steady;
3. the hole of little stud being passed large top cover be screwed into the main shaft upper end screwed hole in;
4. hydraulic jack is placed on the large top cover;
5. little top cover is passed little stud and place on the hydraulic jack, screw on little high nut;
6. startup hydraulic jack is pulled out main shaft from the centre bore of table base.
The invention has the beneficial effects as follows: utilize hydraulic jack that main shaft is mounted and dismounted.Like this, not only reduce operator's labour intensity, and well guaranteed the precision behind the Assembly of the parts, also solved the difficult problem of main shaft dismounting difficulty simultaneously.The method is simple and reliable, and is workable, and assembly precision is high.
