For realizing above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is achieved through the following technical solutions：
A kind of wandering star type polishing machine gear ring elevating mechanism, the mechanism include that gear ring and central shaft, the gear ring are arranged on
On gear ring support, the gear ring support is affixed with the gear ring of lower section set, and the gear ring set is lifted with gear ring gear and gear ring respectively
Rise set affixed, gear ring lifting set lifting upper plate synchronous with lower section is affixed, and the synchronous lifting upper plate is synchronous with lower section
Bar Joint, together with the synchronizing bar is spun with a lifting nut, the lifting nut is by baffle ring and corresponding axle gear
Circle is axially positioned in support set, and the lifting nut is rotatably arranged in support set by bearing, the lifting spiral shell
Mother is fixed together with a lifting gear, the lifting gear and a lifting external toothing engaged transmission, the lifting external toothing by
Lifting reducing motor, lifting driving gear, lifting idle pulley form gear transmission chain and drive.
Further, the synchronous lifting upper plate is also fixed together with a fixed plate of outer, in the fixed plate
Fix bar is provided with, in the fix bar, stroke dog is connected with, gear ring lifting row is limited by stroke dog in running
Journey.
Further, bearing is provided between the gear ring set and gear ring lifting set.
Further, lifting driving gear, the lifting driving tooth are installed on the output shaft of the lifting reducing motor
Wheel engages and drives lifting idle pulley, the lifting idle pulley to engage and drive lifting external toothing.
Further, the lifting external toothing engages and drives multiple lifting gears for being distributed in its edge.
Further, multiple stroke dogs are connected with the fix bar, and by adjusting the position of the stroke dog
Put the bound extreme position that sets gear ring.
The invention has the beneficial effects as follows:
The present invention is compared with several lifting modes above with advantages below：
Compared with the first, due to promoting the up-down mode of cam, the height and position of gear ring pass through to adjust using cylinder
The position of whole cylinder Limit screw is regularly manually adjusted.
Compared with second, three screw pairs are driven using Chain conveyer, as Chain conveyer stability is poor, transmission accuracy is low,
Synchronizing bar is easily formed during lifting asynchronous, cause gear ring lifting set stuck.
Summary.This constitutional detail is simple, and processing, easy to assembly, lifting high transmission accuracy, reliability height are economical real
With.
