Abstract
The utility model relates to a grinding spindle used for grinding a ball nut for a ball screw. The spindle structurally comprises a quill, a grinding wheel and a driving mechanism, wherein the quill is cylindrical; the grinding wheel is arranged at the front end of the quill, and provided with a rotating shaft which is inclined relatively to the central shaft of the quill; the driving mechanism drives the grinding wheel to rotate, and is provided with a magnetic force shaft coupling; the opposite ends of a driving shaft and a grinding wheel shaft are connected in a non-contacting manner through the magnetic force shaft coupling; the rotating power of the driving shaft is transferred to the grinding wheel shaft through magnetic force.
Description
Technical field
The utility model relates to the grinding spindle that the rotating shaft of emery wheel grinding spindle (spindle) for grinding machine, that make to be configured in quill (quill) front end arranges obliquely with respect to the driving shaft that is configured in quill inside.
Background technology
In the mode that the rotation of emery wheel is tilted with respect to main shaft, carrying out in the screw grinder of grinding, only with thread groove (for example, the thread groove of ball nut) the equal angle of lead angle, the rotation of emery wheel is tilted with respect to main shaft, while making the emery wheel that is shaped to the shape identical with the cross sectional shape of thread groove move and carry out grinding along thread groove, thus, thread groove is processed as to correct shape.
In this case, the driving shaft of quill inside and the rotating shaft of emery wheel are in being with angled relation, therefore for example in patent documentation 1, disclose a kind of technology, with bevel gear, the rotation of the driving shaft of quill inside has been passed to the rotating shaft of emery wheel.
But, in the prior art, owing to using gear in the transmission of power, so there is the problem that produces vibration and noise, makes the machining accuracy deterioration of roller surface.

Utility model content
The utility model In view of the foregoing provides a kind of grinding spindle, this grinding spindle simple in structure, even and in the situation that the angle between the driving shaft of quill inside and the rotating shaft of emery wheel is larger, also can reduce vibration and noise, and to emery wheel transmission rotary power at a high speed.
The utility model is in order to solve above-mentioned problem, and adopts following technical scheme.
(1) a kind of grinding spindle, its rotation that makes to be configured in the emery wheel of quill front end arranges obliquely with respect to the axis that is configured in the driving shaft of described quill inside, wherein, as the rotary power of driving shaft is passed to described emery wheel rotating shaft mechanism and be provided with magnetic coupling, this magnetic coupling will link and by magnetic force, the rotary power of driving shaft is passed to rotating shaft in non-contacting mode between driving shaft and the opposed end of rotating shaft.
(2) be preferably, in above-mentioned (1), magnetic coupling consists of a pair of umbrella parts that are incorporated into respectively the opposed end separately of driving shaft and rotating shaft and outer peripheral face is approached in non-contacting mode mutually, and on the outer peripheral face respect to one another of umbrella parts, assortment has the magnet that produces magnetic force.
Because grinding spindle of the present utility model is used magnetic coupling, and rotary power is passed to the rotating shaft of emery wheel from the driving shaft of quill inside in non-contacting mode, even if so in the situation that the angle of inclination of the rotating shaft of emery wheel is larger, can not produce wearing and tearing and noise as the situation of use bevel gear yet.
Accompanying drawing explanation
Fig. 1 means the figure of grinding spindle of the present utility model.
The specific embodiment
The grinding spindle of present embodiment by columned quill 51, be configured in the front end of quill 51 and the driving mechanism that has the emery wheel 15 of the rotating shaft Y tilting with respect to the central shaft X of quill and emery wheel 15 is rotarilyd actuate forms, driving mechanism has magnetic coupling 70, this magnetic coupling 70 will link in non-contacting mode between driving shaft 52 and the opposed end of grinding wheel spindle 61, and by magnetic force, the rotary power of driving shaft 52 is passed to grinding wheel spindle 61.
Embodiment
Inside in quill 51 and quill holder 3 is provided with bearing hole 51a, 3a, and in these bearing hole 51a, 3a, via bearing 4,5, rotation contains driving shaft 52 freely.At the leading section of quill 51, rotation is supported with the grinding wheel spindle 62 and the emery wheel 15 that only tilt with angle [alpha] 2 with respect to the axis X of driving shaft 52 freely.The leading section devices spaced apart ground configuration of the base end part of grinding wheel spindle 62 and driving shaft 52, links in non-contacting mode by magnetic coupling 70 between these grinding wheel spindles 62 and the opposed end of driving shaft 52.
According to the grinding spindle forming in this wise, the rotary power of driving shaft 52 is passed to grinding wheel spindle 62 in non-contacting mode, therefore, even in the situation that the tilt angle alpha 2 of grinding wheel spindle 62 is larger, can not produce vibration and the noise as gear, can transmit rotary power at a high speed to grinding wheel spindle 62 yet.Therefore, can easily tackle the nut processing of large lead angle.
Claims (2)
1. a grinding spindle, its rotation that makes to be configured in the emery wheel of quill front end arranges obliquely with respect to the axis that is configured in the driving shaft of described quill inside, it is characterized in that, as the rotary power of described driving shaft is passed to described emery wheel rotating shaft mechanism and be provided with magnetic coupling, this magnetic coupling will link and by magnetic force, the rotary power of described driving shaft is passed to described rotating shaft in non-contacting mode between described driving shaft and the opposed end of rotating shaft.
2. grinding spindle according to claim 1, it is characterized in that, described magnetic coupling consists of a pair of umbrella parts that are incorporated into respectively the opposed end separately of described driving shaft and rotating shaft and outer peripheral face is approached in non-contacting mode mutually, and on the outer peripheral face respect to one another of described umbrella parts, assortment has the magnet that produces described magnetic force.
