Description
[technical field]
The utility model relates to a kind of stepping motor, particularly a kind of axial linear movement stepping motor.
[background technology] motor
When conventional motor will realize axial linear movement, need motor output shaft connects a screw rod by shaft joint, screw rod is threaded with slide.During work, motor output shaft drives screw rod to rotate together, to realize the axial linear movement of motor relative to slide.In prior art, motor needs spinning movement to coordinate axial straight line by shaft joint and screw rod, and tool drive mechanism is complicated, and part is many, and production cost is high, safeguards inconvenient.
[utility model content]
The utility model provides a kind of structure axial linear movement stepping motor simple, easy to use.
In order to solve above-mentioned Problems existing, the utility model have employed following technical proposal:
Axial linear movement stepping motor, comprise stator module and rotor assembly, stator module comprises stator, it is characterized in that, rotor assembly comprise a screw rod with the hollow thread axle of rotor around central rotation, screw rod is through axis hole, screw rod and the shaft hole diameter threaded engagement of hollow thread axle.
Axial linear movement stepping motor described above, it is characterized in that: the axis hole of described hollow thread axle is that two ends internal diameter is large and the step nibs that interlude internal diameter is little, the interlude inwall that internal diameter is little is provided with internal thread, the external screw thread of screw rod excircle and above-mentioned internal thread threaded engagement, the clearance position preventing screw rod and shaft hole inner wall from rubbing is left at the two ends of hollow thread axle.
Axial linear movement stepping motor described above, is characterized in that: the clearance position spacing between the axis hole two ends internal diameter of described hollow thread axle and screw rod excircle is 0.5 ~ 1 millimeter.
Axial linear movement stepping motor described above, is characterized in that: motor is linked formed by forward and backward end cap, stator module, rotor assembly, and described hollow thread axle two ends are overcoat bearing respectively, and two bearings is built in front and rear cover respectively.
During utility model works, in screw rod fixed glides, motor is fixedly connected on fixed head, and when motor hollow thread axle rotates, screw rod and slide plate be relative motor rectilinear motion together, thus realizes motor axial linear movement.
The beneficial effects of the utility model are:
1, in screw rod fixed glides, after energising, when hollow thread axle rotates, the relative motor of screw rod does rectilinear motion, thus motor realizes axial linear movement, and overall structure is simple, now for the syndeton adopting output shaft to coordinate shaft coupling, screw rod in prior art, the utility model structure is simple, and cost is low, is conducive to promoting the use of.
2, the axis hole of hollow thread axle is that two ends internal diameter is large and the step nibs that interlude internal diameter is little, the interlude inwall that internal diameter is little is provided with internal thread, the external screw thread of screw rod excircle and internal thread threaded engagement, the clearance position preventing screw rod and shaft hole inner wall from rubbing is left at the two ends of hollow thread axle, avoid axis hole and screw rod at the volley because installation accuracy error or screw rod slight bending produce the noise and wearing and tearing of interfering and causing, be conducive to extending the utility model useful life, easy to use.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that the utility model master cuts open structural representation.
Fig. 2 is that in the utility model, motor master cuts open structural representation.
Fig. 3 is screw-rod structure schematic diagram in the utility model.
[embodiment]
As shown in Figure 1, Figure 2 and Figure 3, axial linear movement motor, motor is linked formed by forward and backward end cap, stator module 1, rotor assembly, stator module comprises stator, rotor assembly comprise a screw rod 4 with the hollow thread axle 2 of rotor around central rotation, hollow thread axle two ends are overcoat bearing 3 respectively, and two bearings 3 is built in front and rear cover respectively.Screw rod 4 is through the axis hole 21 of hollow thread axle 2, and screw rod 4 coordinates with axis hole 21 internal diameter whorl.Wherein, the axis hole 21 of hollow thread axle is that two ends internal diameter is large and the step nibs that interlude internal diameter is little, and the interlude inwall that internal diameter is little is provided with internal thread 22, and screw rod 4 is through the axis hole 21 of hollow thread axle 2, and screw rod 4 two ends are stretched out outside hollow thread axle two ends respectively; The external screw thread of screw rod 4 excircle is threaded with above-mentioned internal thread, the clearance position 5 preventing screw rod and shaft hole inner wall from rubbing is left at the two ends that the shaft hole diameter of hollow thread axle is large, and the clearance position spacing between the axis hole two ends internal diameter of hollow thread axle and screw rod excircle is 0.5 ~ 1 millimeter.
During utility model works, screw rod 4 is fixed on a slide plate, and motor is fixedly connected on fixed head, and when hollow thread axle 2 rotates, screw rod 4 is motor rectilinear motion relatively, thus realizes motor axial linear movement.
The utility model is not limited to above-mentioned execution mode, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then intention of the present utility model also comprises these changes and distortion.
This axial linear movement stepping motor is applicable to the multiple stepping motors such as 28,35,39,42,57,60,86,110,130 seat No..
