Abstract
The invention belongs to sewing machine technology and discloses a novel connection structure in which a direct-drive servo motor of a sewing machine is connected with an upper shaft of the sewing machine. The connection structure comprises a motor 1, a motor shaft 2, the upper shaft 3 of the sewing machine, a connection screw 4, a connection sleeve 5, a bearing 6 and a machine shell 7 and is characterized in that: the motor shaft 2 and the upper shaft 3 of the sewing machine are connected together by the connection sleeve 5; and the connection sleeve 5 is stage-like, and three threaded holes 51 which are uniformly distributed at equal intervals of 120 degrees are required to be formed on the two small-diameter ends of the connection sleeve 5 for fastening the upper shaft 3 of the sewing machine on the motor shaft 2.
Description
Technical field:
The invention belongs to sewing machine technique, be connected a kind of new structure of design at the motor that directly drives computer controlled sewing machine with axle on the Sewing machines.
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 present invention 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.
Summary of the invention:
The objective of the invention is last a kind of new syndeton that is connected and designs with direct-drive type servomotor with the Sewing machines of Sewing machines.
The present invention includes 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 of the present invention 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 of the present invention 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 present invention 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 a schematic three dimensional views of the present invention, and Fig. 2 is the schematic diagram of motor adapter sleeve part quadruplication of the present invention
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.
