Abstract
The utility model discloses a lengthened boring head guiding device which is arranged between a boring head and a boring rod and comprises a guide bar and a guide sleeve. The guide sleeve is used for increasing guide length. Two ends of the guide sleeve are respectively connected with the boring head and the boring rod, and the guide bar is fixed on the guide sleeve. The guide sleeve comprises a boring head connector and a boring rod connector which are welded together to form a guide sleeve, the boring head connector is connected with the boring head through a square thread, and the boring rod connector is connected with the boring rod through another square thread. The guide bar is fixed on the guide sleeve through screws and made of high polymer materials. The guide sleeve used for increasing the guide length is arranged between the boring head and the boring rod, the boring head guiding device capable of guaranteeing linear motion accuracy of the boring head is added on the original base and is reasonable in structure, the guide length is greatly increased, and the linear motion accuracy of the boring head is guaranteed.
Description
Technical field
The utility model relates to Boring machine processing technical field, particularly a kind of device that lengthens boring head guiding.
Background technology
In deep hole boring machine processing, boring head need move as straight-line feed along boring head guiding, and boring head generally transmits this straight-line feed motion by four long keys of guiding, and the long key that leads is longer, and its precision of rectilinear motion that can transmit is just higher.On general deep hole boring machine, boring head is to be directly connected on boring bar by square thread, is subject to its structural constraint, and the long key length of guiding is subject to certain restrictions, and easily causes bore hole off-axis, forms inside and outside circle decentraction.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of device that lengthens boring head guiding is provided, and it can guarantee boring head precision of rectilinear motion.
The technical solution of the utility model is: the device of described lengthening boring head guiding, be arranged between boring head and boring bar, and comprise gib block and the fairlead that is used for increasing guiding length; The two ends of described fairlead connect respectively boring head and boring bar, and described gib block is fixed on fairlead.
Described fairlead comprises boring head connector and boring bar connector; Described boring head connector and boring bar connector are combined formation fairlead by soldering group.Boring head connector is connected with boring head by square thread, and boring bar connector is connected with boring bar by square thread.
Described gib block is fixed by screws on fairlead.Described gib block adopts macromolecular material.
The utility model arranges a fairlead that increases guiding length between boring head and boring bar, increase on the original basis a boring head guider of guaranteeing boring head precision of rectilinear motion, it is rational in infrastructure, has greatly increased guiding length, thereby guarantees the precision of rectilinear motion of boring head.
