Abstract
The utility model relates to a technique of an industrial sewing machine, in particular to a servo motor for a hollow rotor of a direct-drive industrial sewing machine. A driving motor of the current industrial sewing machine has the defects that the transmission part has complex structure and high requirements for machining and assembling to cause narrow adaptability of the industrial sewing machine. In the servo motor for the hollow rotor of the direct-drive industrial sewing machine, a rotor (5) is of a hollow structure, and the upper part of the hollow rotor (5) is provided with a servo motor rotor inner tightened sleeve (1) of a tapered structure, which is sleeved between a main shaft (11) of the industrial sewing machine and the hollow rotor (5) of the servo motor. The utility model has simple structure, convenient use, compact handpiece structure and good coordinated concentricity and overcomes the defects of belt transmission of the traditional industrial sewing machine.
Description
Technical field
The utility model relates to the industrial sewing machine technology, specifically is meant a kind of direct-drive type industrial sewing machine air-core armature servomotor.
Background technology
The drive motors that is used for industrial sewing machine at present has ac synchronous motor, variable-frequency motor, AC servo motor etc.The kind of drive of they and head is belt transmission or directly drives through shaft joint.The shortcoming of these kinds of drive is: drive disk assembly is many, complex structure, and drive disk assembly processing and matching requirements height cause the adaptability of industrial sewing machine wideless.Therefore invent a kind of simple in structure, drive disk assembly processing and assembling easily, easy to use, the direct-drive type industrial sewing machine air-core armature servomotor of industrial sewing machine wide accommodation is very necessary.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and drive disk assembly processing is easy, easy to use with assembling, the direct-drive type industrial sewing machine air-core armature servomotor of industrial sewing machine wide accommodation.
The purpose of this utility model is achieved in that
A kind of direct-drive type industrial sewing machine air-core armature servomotor, form by motor housing, stator, air-core armature, end cap, bearing, air-core armature is a hollow core structures, be provided with in the servo motor rotor tightly cover on the top of air-core armature, tight cover is enclosed between industrial sewing machine main shaft and the servomotor air-core armature for cone structure in the rotor.
Air-core armature is made by hollow sleeve pipe and some blocks of permanent magnetic materials, and an end of air-core armature is provided with external screw thread, and tightens nut and matches; Other end conehead partly is cut into two pairs of notches and matches with industrial sewing machine main shaft external diameter.
End cap is connected with the flexible fastening sheet, and on the servomotor end cap, the other end is mounted on the body of sewing machine an end of flexible fastening sheet with the stator screw.
Tight cover is cone structure in the rotor, and an end of cone has some notches and can uphold, and the other end is provided with external screw thread.
Main points of the present utility model are: use servo motor rotor inner diameter volume and industrial supporting connection of seam machine main shaft.
The servomotor shell is packed into and end cap is installed behind field frame assembly and the rotor assembly, locks with trip bolt again.The bearing of packing between servomotor shell and end cap is inserted in tight cover in the servomotor, and the tight cover other end is locked nut in the servomotor.Servomotor flexible fastening sheet is installed on the corresponding screw of end cap.
Tight cover internal diameter is excessive the cooperation with industrial seam machine main shaft in the servomotor, external diameter is that cone structure has two pairs of grooving mouths can uphold and servo motor rotor internal diameter tight fit, when in tightening servomotor, tightly overlapping nut, interior tight cover cone is pulled to servo motor rotor endoporus direction, and awl body structure Po makes the interior tightly cover of servomotor hold under the arm tightly with industrial seam machine main shaft and servomotor.Field frame assembly is made up of coil, stator core, winding lead-out wire; Rotor assembly is that air-core armature is formed by permanent magnetic material and armature spindle.
The utility model has the advantages that:
1. simple in structure, easy to use.
2. the handpiece structure compactness of industrial sewing machine. cooperate good concentricity.
3. replace and have now in industrial sewing machine belt transmission and shaft joint transmission; Overcome the shortcoming of existing industrial sewing machine motor driven mode.
4. use industrial sewing machine wide accommodation of the present utility model.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the utility model component-assembled figure.
Among the figure: 1 is tight cover in the servo motor rotor; 2 is bearing; 3 is screw; 4 is electric motor end cap; 5 is air-core armature; 6 is motor stator; 7 is the servomotor shell; 8 is nut; 9 are the flexible fastening sheet; 10 are flexible fastening sheet screw; 11 is machine spindle.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As books 1 and shown in Figure 2: the motor stator 6 of packing in the servomotor shell 7 of the present utility model, the air-core armature 5 of in motor stator 6, packing into, air-core armature 5 is made up of hollow sleeve pipe and 8 block permanent magnets.Load onto electric motor end cap 4, be pressed into bearing 2 in the relevant position of servomotor shell 7 and electric motor end cap 4.It is rotatable with the corresponding magnetic gap of air-core armature 5 formation to be pressed into bearing 2 rear motor stators 6.The external diameter of root a tree name industrial sewing machine main shaft 11, tight cover 1 in the preparation servo motor rotor; Tight cover 1 is a cone structure in the rotor.Interior tight cover 1 outer wall and air-core armature closely cooperate.The conehead of the interior tight cover 1 of servo motor rotor partly is cut into two pairs of notches can uphold and machine spindle 11 interference fits.After tight cover 1 is inserted in industrial sewing machine main shaft 11 in the servo motor rotor, locks and tighten nut 8, locking nut 8 draws in tight cover 1 in the servomotor in the air-core armature 5, and industrial sewing machine main shaft 11 and servomotor air-core armature 5 are fixedly secured; Thereby servo motor rotor 5 and industrial sewing machine are rotated synchronously, realized tightening in the servomotor connection industrial sewing machine main shaft 11, guarantee the concentricity of servomotor and industrial sewing machine.Flexible fastening sheet 9 is made the stator at the relative right angle of book type for elastic steel sheet, designs according to elastic steel sheet book type direction elastic principle; One end is fixed on the servomotor end cap 4 with flexible fastening sheet screw 10, and the other end is fixed on the body that is mounted sewing machine with screw 3.Stator 9 is used the elastic steel sheet in-plane and is subtracted the error made from assembling with relative right-angle plane direction pin, guarantees the synchronous smooth and easy rotation of servo motor rotor and machine spindle.
