Abstract
The invention discloses a boring bar guide device. The boring bar guide device comprises milling shafts; each milling shaft is provided with a long guide key; and the ends of the milling shafts are provided with two guide end face keys which can increase the guide length. The boring bar guide device has a reasonable structure and greatly increases the guide length so as to ensure the linear movement accuracy of a boring bar.
Description
Technical field
The present invention relates to a kind of boring bar guider of boring machine.
Background technology
In boring machine, boring bar needs to make the axial straight-line feed of Z along milling spindle and moves, milling spindle generally transmits this straight-line feed motion by 2 long keys of guiding, the long key that leads is long more, its precision of rectilinear motion that can transmit is just high more, but owing to be subjected to its structural constraint, the long key length of guiding is subjected to certain restriction.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, guarantee the boring bar guider of boring bar precision of rectilinear motion.
Technical solution of the present invention is:
A kind of boring bar guider comprises milling spindle, and the long key of dress guiding on the milling spindle is characterized in that: two guiding straight end-face keys that increase guiding length are set in the end of milling spindle.
The present invention is rational in infrastructure, has greatly increased guiding length, thereby guarantees the precision of rectilinear motion of boring bar.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
A kind of boring bar guider comprises milling spindle 1, and the long key 2 of dress guiding on the milling spindle is provided with two guiding straight end-face keys 3 that increase guiding length in the end of milling spindle.Also want boring bar 4, gear 5, ram 6, bearing 7 among the figure.
Claims (1)
1. a boring bar guider comprises milling spindle, and the long key of dress guiding on the milling spindle is characterized in that: two guiding straight end-face keys that increase guiding length are set in the end of milling spindle.
