Technical field
The utility model relates to a kind of shaft rotating motor, and 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 complexity, 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.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of screw grinder with the synchronous headstock spindle motor of direct-drive permanent-magnetism.Of the present utility model simple and compact for structure, and can improve the thread grinding precision of screw grinder greatly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of screw grinder is with the synchronous headstock spindle motor of direct-drive permanent-magnetism, comprise shell, rotating shaft, the p-m rotor assembly, stator module, encoder, front end housing and rear end cap, described rotating shaft is arranged on enclosure by bearing one and bearing two, and described rotating shaft stretches out from rear end cap, described front end housing is installed in the front end of shell, described rear end cap is installed in the rear end of shell, front end and described encoder that described encoder is installed in rotating shaft are connected with external driver, it is characterized in that: described shell roughly is square, described p-m rotor assembly is installed on the rotating shaft and accounts for 1/2nd to 3/4ths of described shell inward turning shaft length, and described stator module is arranged on enclosure and described 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 described p-m rotor assembly accounts for 2/3rds of described 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 described rotating shaft stretches out from rear end cap is provided with the duct that is used for fixing workpiece.
The utility model compared with prior art has the following advantages: of the present utility model simple and compact for structure, and can improve the thread grinding precision of screw grinder greatly.Roughly be square by described shell, described p-m rotor assembly is installed on the rotating shaft and accounts for 1/2nd to 3/4ths of described shell inward turning shaft length, preferably, described 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 the workpiece that is ground, described workpiece such as leading screw etc.Of the present utility model simple and compact for structure, and can improve the thread grinding precision of screw grinder greatly.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
