Abstract
The present invention relates to a planetary polishing machine flexible drive mechanism, which comprises a lower disk shaft adopted as the input shaft, wherein the lower disk shaft and a lower disk shaft flange are fixedly connected, the outer ring of the lower disk shaft flange and the upper cover inner ring of a hydraulic bearing assembly are matchedly arranged, a plurality of semicircular turning grooves are uniformly distributed on the outer ring of the lower disk shaft flange, semicircular turning grooves with the same number are uniformly distributed on the upper cover inner ring of the hydraulic bearing assembly, the semicircular turning grooves on the outer ring of the lower disk shaft flange and the semicircular turning grooves on the upper cover inner ring of the hydraulic bearing assembly are corresponding to each other one by one so as to form plural groups of cylindrical holes, and a group of a pin turning assembly comprising a steel rod and a nylon sleeve is arranged into each group of the cylindrical holes. According to the present invention, the difficult problem of the hydraulic shaft assembly and input shaft connection is solved, and the steel rod and nylon sleeve combined flexible connection is adopted so as to improve the stability and the processing precision of the equipment, and reduce the failure rate and the maintenance difficulty of the equipment.
Description
Technical field
The invention belongs to planetary grinding/polishing machine field, be specifically related to a kind of planetary grinding/polishing machine flexible drive mechanism.
Background technique
In traditional planetary grinding/polishing machine equipment, usually adopt crossed roller bearing to drive lower wall, equipment precision is poor, bearing capacity is low, and along with development in science and technology, market demand equipment precision is more and more higher, bearing capacity is increasing, and traditional crossed roller bearing can not be met the need of market.Comply with the market demand, high-precision hydraulic bearing unit is adopted to replace traditional crossed roller bearing in planetary grinding/polishing machine equipment, improve equipment precision and bearing capacity, and by structural limitations, traditional Placement can not meet topology requirement, and the connection between fluid bearing assembly and input shaft just becomes technological difficulties.
Summary of the invention
The object of the invention is to overcome prior art Problems existing, provide a kind of wandering star type buffing machine flexible drive mechanism, the stability of lifting means, machining accuracy, reduce the rate of fault of equipment, maintenance difficulty simultaneously.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of wandering star type buffing machine flexible drive mechanism, this mechanism comprises the lower wall axle as input shaft, described lower wall axle and lower wall shaft flange Joint, match with the upper cover inner ring of a fluid bearing assembly and install in described lower wall shaft flange outer ring, described lower wall shaft flange outer ring is evenly equipped with multiple semicircle allocating slot, and uniform same number of semicircle allocating slot on the upper cover inner ring of described fluid bearing assembly, semicircle allocating slot one_to_one corresponding on semicircle allocating slot on described lower wall shaft flange outer ring and the upper cover inner ring of fluid bearing assembly forms organizes cylindrical hole more, often organize the finger assembly loading in cylindrical hole and be made up of one group of rod iron and nylon jacket, described lower wall shaft flange is by finger Component driver fluid bearing assembly, form flexible drive mechanism.
Further, described lower wall shaft flange exterior edge face is connected with gland.
Further, the geomery of described gland covers rod iron end face at least partly and is axially formed spacing to it.
Further, between described rod iron and nylon jacket be interference fit.
Further, described fluid bearing assembly and fluid bearing assembly are respectively equipped with eight semicircle allocating slots, and form eight groups of cylindrical holes.
The invention has the beneficial effects as follows:
1, in the present invention, lower wall shaft flange and lower wall axle are connected, uniform 8 semicircle allocating slots on lower wall shaft flange outer ring, correspondingly with 8 semicircle allocating slots uniform on the upper cover inner ring in fluid bearing assembly form 8 groups of cylindrical holes, 8 groups of rod irons and nylon jacket assembly is loaded in cylindrical hole, so not only solve the difficult problem that tradition can not be used to be connected by structural limitations fluid bearing assembly and lower wall shaft flange, and compared with traditional connection, adopt herein and flexibly connect, both comparatively high pulling torque be can transmit, and precision and the stationarity of transmission significantly can be promoted again.
2, the combination flexible drive mechanism of the present invention's employing, can make the axis of fluid bearing and the perfection of radial location function play, ensure the machining accuracy of equipment, effectively reduce again the difficulty of processing of part, decrease the processing cost of equipment; Dismounting is simple simultaneously, is convenient to maintenance, decreases the maintenance cost of equipment.
