Abstract
The utility model pertains to sewing machine technology. The new connection device is designed to avoid poor control precision caused by the electric motor of the direct drive computer sewing machine and operation equipments of the current sewing machine. The utility model includes an electric motor 1, a motor-hollow axle 2, a sewing machine upper axle 3, and a connection screw 4. The axle of the electric motor 1 is designed to be hollow, the sewing machine upper axle 3 is lengthened, and the whole upper axle passes through the motor-hollow axle 2. Meanwhile the two devices are tight coupled and fixed together by two connection screws 4, therefore the power outputted by the electric motor directly acts on the sewing machine upper axle to improve the control precision.
Description
Technical field:
The utility model belongs to sewing machine technique, is connected a kind of new device of design with axle on the Sewing machines at the motor that directly drives computer controlled sewing machine.
Background technology:
The present Sewing machines that directly drives, all be simply axle on motor output shaft and the Sewing machines to be connected by shaft coupling, since be to connect by shaft coupling, the bad influence that brings on the Sewing machines performances such as noise, vibrations of control accuracy, thus influence whole complete machine effect and operation.The utility model has designed the new jockey of axle on a kind of motor shaft and the Sewing machines, makes its one-tenth as a whole, improves control accuracy, improves the Sewing machines overall performance to greatest extent.
The utility model content:
The purpose of this utility model is the bad and a kind of new jockey that designs of the control accuracy brought of the jockey at the motor that directly drives at present computer controlled sewing machine and Sewing machines.
The utility model comprises axle 3, attachment screw 4 on motor 1, motor-hollow axle 2, the Sewing machines.It is characterized in that the axle of motor 1 is designed to hollow shaft, and, make its integral body pass motor-hollow axle 2, they are closely cooperated, by two attachment screws 4 both are fixed together again 3 lengthenings of axle on the Sewing machines.
The jockey that the utility model has designed on a kind of new motor that directly drives computer controlled sewing machine and the Sewing machines spool, save the destabilizing factor that shaft coupling brings, the erecting device of other Sewing machiness need not change simultaneously, just can realize that motor power output acts directly on axle on the Sewing machines, reduce intermediate link, not only energy-conservation but also reliable, shake little, further increase the start-stop velocity accuracy of Sewing machines, increase the stability of a system, improve the precision of control.
Description of drawings:
Fig. 1 is the utility model connection diagram, and Fig. 2 is the utility model motor-hollow axle schematic diagram
Concrete device for carrying out said:
With reference to Fig. 1, Fig. 2, axle 3 on the Sewing machines is extended on original basis, and be designed to the main shaft of motor 1 hollow, make on the Sewing machines axle 3 can pass completely through motor-hollow axle 2, guarantee to closely cooperate between them simultaneously, with two attachment screws 4 axle 3 on the Sewing machines is fixed on the motor-hollow axle 2 at last, can solves Sewing machines and drive motors, reach the raising performance demands in the bad problem of control accuracy.Reduce intermediate link simultaneously, further increased the start-stop velocity accuracy of Sewing machines, increased the stability of a system.
Claims (2)
1, a kind of jockey that directly drives computer controlled sewing machine comprises axle (3), attachment screw (4) on motor (1), motor-hollow axle (2), the Sewing machines, it is characterized in that the axle of motor (1) is designed to hollow shaft, make on the Sewing machines axle (3) integral body pass motor-hollow axle (2), they are closely cooperated.
2, device according to claim 1, it is characterized in that axle with motor (1) when being designed to hollow shaft axle (3) lengthening on the Sewing machines, by two attachment screws (4) both are fixed together again.
