Abstract

The utility model discloses a centre of an outer support of a gear hobbing, which consists of the outer support and the centre arranged on the outer support; one side of the outer support is vertically provided with a support cylinder; a centre sleeve is embedded in the support cylinder from bottom to top; the centre is arranged in the centre sleeve and connected with the centre sleeve through a swing bearing and a tail bearing; a check ring is arranged on the upper end of a centre tail shaft. The utility model effectively solves the problems of low machining precision and efficiency of gears caused by long cantilever and large friction of the prior gear hobbing; the utility model has a simple structure, high precision and small friction, and is worthy to promote and use.

Description

The gear-hobbing machine support arm is top
Technical field
The utility model relates to a kind of machining equipment, and especially a kind of gear-hobbing machine support arm that rubs little, that precision is high is top.
Background technology
As everyone knows, the general top and top housing of traditional live center is installed as one, the front end of top housing, top housing and top between top floating bearing and top loading bearing are installed, promptly bearing is positioned at top housing chamber, its top cantilever is longer.During use, live center is inserted the tapering drill holder, reinstall in the platform tail sleeve, block bearing is positioned at platform tail outside, because be subjected to the restriction of platform tail sleeve dimensions, the axle journal position radial dimension of top insert division is little, so top diameter of axle position rigidity is poor, yielding, it is little to add the man-hour bearing capacity, add workpiece skew longitudinal center line easily takes place man-hour, be difficult to satisfy the requirement of machining accuracy.Therefore, carry out gear hobbing at gear-hobbing machine and add and usually adopt stationary center man-hour, but stationary center can not rotate, frictional force is big, and top cantilever is also longer simultaneously.
The utility model content
The utility model provides a kind of gear-hobbing machine support arm that rubs little, that precision is high top for the problem that solves the prior art existence.
The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: the gear-hobbing machine support arm is top by support arm and be located at top composition on the support arm, one side of support arm vertically is provided with rack tube, tailstock sleeve embeds in the rack tube from bottom to top, top being arranged in the tailstock sleeve and by floating bearing and tail bearing is connected with tailstock sleeve, and the upper end of top tailing axle is provided with back-up ring.Be arranged in the tailstock sleeve top, and tailstock sleeve embeds rack tube, whole toply have only its pinnacle part to expose rack tube, and it is top not to have cantilever, and radially carrying is big, and top rotation is flexible.
As preferably, top middle part is top axis, and top axis is provided with inner spacing collar, and floating bearing is arranged on the two ends of top axis, is divided into floating bearing and turning down bearing, and the upper end of inner spacing collar connects goes up floating bearing, and the lower end connects the turning down bearing.Inner spacing collar is used for to floating bearing location usefulness up and down, and floating bearing is used for guaranteeing the flexibility of top rotation up and down.
As preferably, the tailstock sleeve lower end is provided with outer shroud, and the upper surface of outer shroud is connected with the lower surface of rack tube, and the tailstock sleeve upper end is provided with interior ring, and the internal diameter of interior ring and the external diameter of top tailing axle are suitable.
As preferably, the diameter of top tailing axle is provided with tail bearing less than top axis on the top tailing axle, and the upper surface of tail bearing is connected with the interior ring lower surface of tailstock sleeve.Being provided with of tail bearing can guarantee toply can also rotate flexibly when being subjected to axial compressive force.
As preferably, top lower end is provided with the convex edge, and the upper end of convex edge is connected with the lower end of turning down bearing.The effect of convex edge is to prevent that the turning down bearing from skidding off tailstock sleeve downwards.
As preferably, the position of back-up ring is above tailstock sleeve, and the lower surface of back-up ring is near the upper surface of ring in the tailstock sleeve.The effect of back-up ring is to prevent from toply to skid off from tailstock sleeve.
The beneficial effects of the utility model are: it is low because of the Gear Processing precision that top arm length, frictional force produce greatly that it has solved present gear-hobbing machine effectively, the problem that efficient is not high, and the utility model is simple in structure, the precision height, frictional force is little, is worth of widely use.
