Abstract
The utility model belongs to sewing machine technology, and discloses a novel connecting structure, which is designed for connecting a direct-drive type servo motor of a sewing machine with an upper shaft of the sewing machine. The connecting structure comprises a motor 1, a motor shaft 2, a sewing machine upper shaft 3, a connecting screw 4, a connecting sleeve 5, a bearing 6 and a casing 7. The connecting structure is characterized in that the motor shaft 2 is connected together with the sewing machine upper shaft 3 via the stepped connecting sleeve 5, and three threaded holes 51 evenly distributed at 120 degrees need to be arranged at two ends, with smaller diameters, of the connecting sleeve 5 and are used for fastening the sewing machine upper shaft 3 and the motor shaft 2.
Description
Technical field:
The utility model belongs to sewing machine technique, is connected a kind of new structure of design with axle on the Sewing machines at the motor that directly drives computer controlled sewing machine.
Background technology:
Traditional industrial sewing machines generally all are to adopt the power of bel-drivenn mode power source output to pass on the Sewing machines, as the power of Sewing machines rotation, in general, because the bel-drivenn limitation can be lost lot of energy in the process of transmission, efficient is lower.And the appearance of small-sized servomotor, then can the transmission of power is direct by becoming indirectly, as long as simply motor output shaft is connected with axle on the Sewing machines, can realize.The utility model has designed the new syndeton 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 a last a kind of new syndeton that is connected and designs with direct-drive type servomotor with the Sewing machines of Sewing machines.
The utility model comprises axle, attachment screw, adapter sleeve, bearing, casing on motor, motor shaft, the Sewing machines, it is characterized in that motor shaft being connected together with axle on the Sewing machines by adapter sleeve, use attachment screw fastening again, axle is become one.Adapter sleeve described in the utility model is stepped, and the two ends outside diameter is little, and middle one section diameter is bigger, and the two ends that diameter is little are not connected with other parts, so need not process, one section that mid diameter is big needs to process and then cooperate with bearing, and integral body is packed in the casing then.The less two ends of adapter sleeve diameter described in the utility model need be opened three screwed holes and are the evenly distribution of 120 degree, in order to axle and motor shaft on the fastening Sewing machines.
The utility model has designed the syndeton of axle on a kind of new motor shaft and the Sewing machines, need not change other erecting devices of Sewing machines, just can realize that motor power output acts directly on axle on the Sewing machines, reduced intermediate link, not only energy-conservation but also reliable, shake for a short time, further increase the start-stop velocity accuracy of Sewing machines, increase the stability of a system, improved the precision of control.
Description of drawings:
Fig. 1 is the utility model schematic three dimensional views, and Fig. 2 is the schematic diagram of the utility model motor adapter sleeve part quadruplication
Concrete device for carrying out said:
With reference to Fig. 1, Fig. 2, adapter sleeve 5 is connected with motor shaft 2, fixing with attachment screw 4, then bearing 6 is enclosed within on bigger one section of adapter sleeve 5 mid diameters, motor 1 is fixed on the rear portion of casing 7 again, bearing 6 is installed on the casing 7 simultaneously, axle 3 on the Sewing machines is passed casing 7, pack into from casing 7 front portions, tighten together, axle 3 and motor shaft 2 are connected as a single entity by attachment screw 4 and adapter sleeve 5.
Claims (3)
1. a syndeton comprises axle (3), attachment screw (4), adapter sleeve (5), bearing (6), casing (7) on motor (1), motor shaft (2), the Sewing machines, it is characterized in that by adapter sleeve (5) motor shaft (2) being connected together with axle (3) on the Sewing machines.
2. a kind of syndeton according to claim 1 is characterized in that described adapter sleeve (5) is stepped, and the two ends outside diameter is little, and middle one section diameter is bigger.
3. a kind of syndeton according to claim 1 is characterized in that the less two ends of described adapter sleeve (5) diameter need open three screwed holes (51), is 120 degree and evenly distributes.
