Description
Technical field
The present invention relates to a kind of spindle motor, particularly a kind of synchronous spindle motor of AC permanent-magnet that is used for tapping machine.
Background technology
Tapping machine is the machining equipment that a kind of medial surface of hole of the part in various through holes with different size such as parts housing, equipment end face, nut, ring flange or blind hole processes internal thread, screw or makes tooth buckle.Tapping machine can be divided into hand tapping machine, pneumatic tapper, electric tapper and hydraulic pressure threading machine etc.; Different according to the master spindle for tapping machine number, can be divided into single shaft tapping machine, four tapping machines of two tapping machines, six tapping machines, multiaxis tapping machine etc.
At present for electric tapper, its structure and speed adjusting gear more complicated, the rotary inertia of rotating shaft is excessive, and the rotation of rotating shaft is corresponding slow, causes job failure easily, influences the operating efficiency of tapping machine, for the work of reality has brought very big inconvenience.Secondly the belt transmission that adopts mostly between general tapping machine motor and the main shaft load easy belt creep when excessive occurs at tapping process, can cause bigger tapping error.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, a kind of synchronous spindle motor of AC permanent-magnet that is used for tapping machine is provided.The present invention can improve the operating efficiency of tapping machine, and it is simple in structure, easy to use, be convenient to promote the use of.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: the synchronous spindle motor of AC permanent-magnet that is used for tapping machine; It is characterized in that: comprise shell, rotating shaft, p-m rotor assembly, stator module, encoder, front end housing and rear end cap, 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; Said rotating shaft is arranged on enclosure and is connected with rear end cap with front end housing respectively with bearing two through bearing one; Said p-m rotor assembly is installed on the rotating shaft, and said stator module is arranged on outer casing inner wall and corresponding with said p-m rotor assembly, and rear end and said encoder that said encoder is installed in rotating shaft are connected with external driver; Said rotating shaft is a hollow-core construction, and the cross section of its hollow-core construction is a variable cross-section.
The above-mentioned synchronous spindle motor of the AC permanent-magnet that is used for tapping machine is provided with sealing ring between said rotating shaft and the front end housing.
The above-mentioned synchronous spindle motor of the AC permanent-magnet that is used for tapping machine, said stator module is positioned at the center of outer casing inner wall.
The present invention compared with prior art has the following advantages: the present invention can improve the operating efficiency of tapping machine, and it is simple in structure, easy to use, be convenient to promote the use of.After the rotating shaft that is used for the synchronous spindle motor of AC permanent-magnet of tapping machine according to the invention adopts hollow structure; Rotary inertia significantly reduces; Rotating speed response is faster; Adaptation is just being changeed tapping, is being reversed and move back the real work needs of screw tap especially easily, makes and adopts the tapping machine operating efficiency of the synchronous spindle motor of this AC permanent-magnet to improve greatly.Moreover this invention electric machine main shaft directly drives master spindle for tapping machine, because permagnetic synchronous motor has the adaptive load ability of wide region, can stall, and realized rigid tapping, guaranteed accuracy of thread.
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
