Description
Technical field
The utility model is related to sewing machine technique fields, more particularly to the coupling device of a kind of motor shaft and sewing machine.
Background technology
Sewing machine is the power output completed by motor driving, and conventional sewing machine generally use connects to inserting attachment device
Motor shaft and machine spindle are connect, the connection of current this electrical connector and motor shaft and sewing arbor is susceptible to larger
Size gap.The gap that this connection type is generated when sewing machine works is easy for causing motor shaft and sewing arbor concentric
It spends bad and generates bounce greatly, the long-term work of motor can lead to the abrasion of connector, make later stage maintenance and the company of replacement of user
Connecing device gum cover makes troubles.
Therefore the seamless connectivity for how solving motor shaft and machine spindle, to improve installation concentricity, reduce damage
Consumption, service free are those skilled in the art's problems to be solved.
Utility model content
The purpose of this utility model is to provide the coupling devices of a kind of motor shaft and sewing machine, for solving the prior art
In easy to wear, the problems such as maintenance is inconvenient, connection concentricity is low.
The purpose of this utility model is to provide the coupling devices of a kind of motor shaft and sewing machine, including connector, sewing
Owner's axis, motor shaft, which is characterized in that the connector is hollow cylinder, and the connector outer wall to the center of circle is provided with fastening
Slot, connector outer wall both ends are provided with bolt apertures, and bolt apertures trepanning position in the same direction and is less than the circle with the binding groove
The heart, the connector cartridge type are inserted in the machine spindle and motor shaft, and screw is tight by the binding groove by the bolt apertures
Gu.
Preferably, the bolt apertures trepanning depth is extremely communicated with the binding groove.
Preferably, the binding groove is parallel respectively is opened in the connector both ends or is led to from described connector one end straight line
The other end.
The utility model makes have the characteristics that install high concentricity, reduction loss, service free.
By said program it is found that providing a kind of coupling device of motor shaft and sewing machine, including connector, sewing owner
Axis, motor shaft, connector are hollow cylinder, and connector outer wall to the center of circle is provided with binding groove, and connector outer wall both ends are provided with spiral shell
Hole is connect, bolt apertures trepanning position in the same direction and is less than the center of circle with binding groove, and connector cartridge type is inserted in machine spindle and motor shaft, screw
Binding groove is fastened by bolt apertures.Bolt apertures trepanning depth is extremely communicated with binding groove.Binding groove is parallel respectively to be opened in connector
The other end is led in both ends from connector one end straight line.
The utility model connects machine spindle and motor shaft by electrical connector, has installation concentricity height, reduces
The features such as loss, easy maintenance.
The characteristics of the utility model, sees the detailed description of the drawings of the present case and following preferable embodiment and obtains clear
Ground understands.

Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
The utility model is expanded on further in face in conjunction with specific embodiments.
Referring to Fig. 1, a kind of coupling device of motor shaft and sewing machine, including connector 2, machine spindle 1, motor are provided
Axis 4, connector 2 are hollow cylinder, and 2 outer wall both ends of connector are provided with binding groove 5 and bolt apertures 6,6 trepanning position of bolt apertures with it is tight
Gu slot 5, in the same direction and less than binding groove 5,2 cartridge type of connector is inserted in machine spindle 1 and motor shaft 4, screw 3 will by bolt apertures 6
Binding groove 5 fastens, to lock motor shaft 4 and machine spindle 1.
The 6 hole trepanning depth that are spirally connected extremely are communicated with binding groove 5.
The utility model has the characteristics that install high concentricity, reduction loss, service free.
Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model the utility model also have respectively
Kind changes and improvements, these changes and improvements are both fallen in claimed the scope of the utility model.The requires of the utility model
Protection domain defined by appended claims and its equivalent.
