Description
Technical field
The utility model relates to the special purpose machine tool field of machining, is applicable to the gear unit of two revolution numerical control axles of multi-station digital-controlled polishing machine of disc type or special purpose machine tool.
Background technology
At present, each station of domestic disc type multistation polishing machine, the multi-station digital-controlled polishing machine of disc type only has the single gyroaxis of mechanical type, does not also have two revolution numerical control axle forms.In the single gyroaxis multistation of the mechanical type disc polisher, through chain or cog belt centralized driving, transmission is fairly simple by a motor in the gyration of each station.If on disc type multistation polishing machine, realize two revolution numerical control axles; Two servomotors need be installed on each station; Along with rotating disk rotates together, its electrical source of power and control signal must be passed through conducting slip ring and solved, and each station servomotor is along with disk rotates; The residing station of servomotor position constantly changes, and make the procedure difference of each station will be difficult to accomplish.Can only be the procedure of each station by the writing of unanimity, the technological parameter that is to say each station is identical.Therefore the function of lathe is restricted.
Summary of the invention
The purpose of the utility model provides the gear unit of the two revolution of a kind of disc type multistation numerical control axle, on the different station of multi-station digital-controlled polishing machine of disc type or special purpose machine tool, accomplishes the different processes content.
The gear unit of the two revolution of the design's disc type multistation numerical control axle; Each station all is provided with two revolution numerical control axles; It is characterized in that being divided into and carry out and drive subdivision: will carry out subdivision respectively and be installed on the rotating disk, will drive subdivision and be installed on the fixed underpan; Between the power transmission shaft of these two subdivisions of processing stations, pass through protruding, the recessed key of circular arc end face; Realize the motion transmission of two revolution numerical control axles, and on fixed underpan, inlay all feather keys that the two revolution numerical control axles that make each station carry out subdivision keep correct attitude when disk turns round.
Beneficial effect of the present invention: compare with disc type multistation polishing machine (or special purpose machine tool) in the past behind the present invention; Realized that each station has two revolution numerical control axles; And each station can be distinguished machining programming, on the different station of a polishing machine (or special purpose machine tool), accomplishes the different processes content.And, simplify the transmission of electrical source of power and control signal and do not needed rotating disk when station exchanges, to lift and fall action, simplified frame for movement, reliability greatly improves.
The key issue that the two revolution of disc type multistation of the present invention numerical control through-drive unit will solve is: the gear unit of the two revolution of each station numerical control axle is divided into two subdivisions: promptly be installed in execution subdivision and the driving subdivision that is installed in fixed underpan on the rotating disk.Between this two each subdivision, connect, accomplish the motion transmission of two revolution numerical control axles through the reliable mechanical structure.Owing to drive the subdivision invariant position, the title of defined numerical control axle is constant with corresponding station procedure.Therefore, its procedure can be different on the different station of a polishing machine.And, because servomotor does not turn round with disk, needn't use conducting slip ring, its reliability is very high.Therefore the present invention has very high economic worth and practical value.
