Preferably, left spindle unit and right spindle unit move the depth of parallelism to main shaft rotation axis along column guide rail direction
No more than 0.014/300mm, it is commonly called as away table.
Main shaft runout is itself required precision of spindle unit in above-mentioned three required precisions, and wheel table and to walk table be then two
The correlation accuracy of a main shaft.Scraping main spindle box guiding rail face when the method for realizing two precision after a main shaft is above-mentioned is lathe assembly
To guarantee to walk meter accuracy requirement, scraping column bottom surface is to guarantee to take turns meter accuracy requirement.
A kind of double axis systems for vertical machining centre that the utility model is mentioned, are installed into vertical machining centre
Afterwards, when lathe is switched on and debugs, by the orienting station of position setting one main shaft of adjustment of encoder, another main shaft is unclamped
Elastic locking ring gland, rotation belt wheel change its relative position, be adjusted to the identical Shi Zaisuo of orienting station of two main shafts
Gland.
The beneficial effects of the utility model are as follows:
(1) keep the running of left and right spindle unit the synchronous drive of the passive belt wheel of left and right main shaft by duplex belt wheel
It is synchronous, thus while improving efficiency, shortening the processing pitch time of either simplex part, the high-quality of guarantee either simplex part with it is consistent
Rate.
(2) in such a way that a slide and two spindle drums combine, so that the precision of left and right main shaft running is protected
While barrier, also facilitates and corrected when error is greater than threshold value.
(3) pass through the configuration of elastic locking ring and the servo motor with built-in encoder, it is convenient that double main shafts are oriented,
The sync rates of double main shaft runnings are further ensured simultaneously.
(4) pass through the requirement of itself precision and correlation accuracy to two spindle units, the operating accuracy of the double main shafts made
