Technical field
The utility model is related to a kind of motor, more particularly, to a kind of penetration type step-by-step linear electric motor.
Background technology
Existing penetration type step-by-step linear electric motor is that female thread structure is made inside armature spindle, is engaged, passes through with leading screw
The mode of worm drive moves the convert rotational motion of motor for straight line moving, as shown in Figure 1.Shown in Fig. 1, motor bag
Include leading screw 1, drive end bearing bracket 2, bearing 3, armature spindle 4, rotor 5, stator 6, rear end cap 7.Existing penetration type stepping straight line is mainly deposited
In following problem：First, the penetration type step-by-step linear electric motor of this form of motor, the difficulty of processing of armature spindle than larger, and
The bad control of precision.2nd, in use, because armature spindle constantly rubs with leading screw in transmission process, rotor can be caused
Life-span can shorten with the abrasion of thread.And with the continuous abrasion of thread, the repetitive positioning accuracy of transmission can be caused
Constantly reduction, finally because precision can not meet use demand and scraps whole motor, use repeatly effect is bad.3rd,
The 26S Proteasome Structure and Function of motor is limited to, armature spindle typically mainly uses metal material, predominantly stainless steel, copper product or metal
Material injection, the selection of material is relatively simple, limits the optimization and upgrading of worm drive transmission accuracy and performance.
Utility model content
The purpose of this utility model is exactly the defect in order to overcome above-mentioned prior art presence and provides a kind of penetration type step
Enter linear electric motors.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of penetration type step-by-step linear electric motor, including screw mandrel and armature spindle, described screw mandrel are axially moved along armature spindle, institute
The motor stated also includes external nut and connecting plate, described connecting plate and armature spindle axial restraint, and rotation synchronous with armature spindle
Turn, described external nut by connecting plate and armature spindle axial restraint, and with armature spindle synchronous rotary.
Described armature spindle is provided with support set.
Described linear electric motors also include connecting bushing, and the connecting bushing is connected after encasing external nut with connecting plate.
Described connecting bushing endoporus is screwed hole, is matched with the external screw thread on connecting plate.
Described external nut selects different types of nut, including plain nut, disappear gap nut or copper nut.
Described external nut is replaceable nut, and nut can select unlike material, different types of nut.
Compared with prior art, the utility model has advantages below：
1. nut is replaceable, extend the service life of penetration type step-by-step linear electric motor.
2. nut is no longer limited by electric machine structure and performance, the more excellent material of material property and precision can be selected more excellent
Disappear gap nut, to lift the overall performance of penetration type step-by-step linear electric motor.
3. compared to the penetration type step-by-step linear electric motor of traditional structure, reduce armature spindle difficulty of processing and by with
The transmission accuracy of penetration type step-by-step linear electric motor can be improved by putting the gap nut that disappears.
4. it is simple and reliable for structure, the difficulty of processing of motor is reduced, production efficiency is substantially increased.
5. versatility is good, different screw pairs can be realized and with a motor Rapid matching, in life by changing nut
During production, stock can be greatly reduced, and greatly improve sample delivery speed.
