Description
Technical field
The present invention relates to a kind of shaft rotating motor, particularly a kind of screw grinder is with the synchronous headstock spindle motor of direct-drive permanent-magnetism.
Background technology
Screw grinder is a kind of thread cutting machine with the various thread form accurate threads of wheel grinding.The traditional work piece type of drive of screw grinder is the belt pulley that adopts on asynchronous motor or the permanent magnet motor rotating shaft driving shaft, passes through belt transmission again, drives reduction box, and the output shaft of last reduction box drives the work piece rotation.There is very big shortcoming in such system, mainly shows following 2 points: the first, its system configuration is complicated, and second, there is the driving error that can not eliminate in the gear drive in the reduction box, can directly influence the precision of thread grinding.Be the very big inconvenience of knowing clearly of the use band of reality.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of screw grinder with the synchronous headstock spindle motor of direct-drive permanent-magnetism.Of the present invention simple and compact for structure, and can improve the thread grinding precision of screw grinder greatly.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: a kind of screw grinder is with the synchronous headstock spindle motor of direct-drive permanent-magnetism; Comprise shell, rotating shaft, p-m rotor assembly, stator module, encoder, front end housing and rear end cap; Said rotating shaft is arranged on enclosure through bearing one and bearing two; And said rotating shaft stretches out from rear end cap, and said front end housing is installed in the front end of shell, and said rear end cap is installed in the rear end of shell; Front end and said encoder that said encoder is installed in rotating shaft are connected with external driver; It is characterized in that: said shell roughly is square, and said p-m rotor assembly is installed on the rotating shaft and accounts for 1/2nd to 3/4ths of said shell inward turning shaft length, and said stator module is arranged on enclosure and said stator module is corresponding with the length of p-m rotor assembly.
Above-mentioned a kind of screw grinder is with the synchronous headstock spindle motor of direct-drive permanent-magnetism, and said p-m rotor assembly accounts for 2/3rds of said shell inward turning shaft length.
Above-mentioned a kind of screw grinder is with the synchronous headstock spindle motor of direct-drive permanent-magnetism, and the position that said rotating shaft stretches out from rear end cap is provided with the duct that is used for fixing workpiece.
The present invention compared with prior art has the following advantages: of the present invention simple and compact for structure, and can improve the thread grinding precision of screw grinder greatly.Roughly be square through said shell; Said p-m rotor assembly is installed on the rotating shaft and accounts for 1/2nd to 3/4ths of said shell inward turning shaft length, and preferred, said p-m rotor assembly accounts for 2/3rds of rotating shaft length; Thereby make stator module and p-m rotor assembly structure be short, thick type; Make its rotating shaft be output as the slow-speed of revolution, high moment of torsion, directly drive by the workpiece of grinding said workpiece such as leading screw etc.Of the present invention simple and compact for structure, and can improve the thread grinding precision of screw grinder greatly.
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
