Problems solved by technology

[0004] A shuttle shaft (i.e. a transmission shaft) cooperating with the machine needle is installed inside the table, and the shuttle shaft moves axially inside the table to achieve the purpose of thread feeding. One end rotates, therefore, the two ends of the shuttle shaft are respectively provided with a moving shaft seat, and a shaft hole is provided on the moving shaft seat. At the same time, the strength of the shaft seat separates the hook shaft from other parts when it rotates. However, because the moving shaft seat is far away from the body of the hook shaft, the size of the moving shaft seat is relatively large, and the space it occupies is also large. When the shuttle shaft rotates, it collides with other parts. During production and processing, the material used in this part is also more, resulting in an increase in investment costs.

Abstract

The invention relates to a sewing machine horizontal transmission shaft and a machining method thereof, and belongs to the technical field of sewing machines. The sewing machine horizontal transmission shaft comprises a main shaft and connecting arms arranged at the two ends of the main shaft respectively. The two ends of the main shaft are provided with movable shaft bases and shaft holes. The two connecting arms are each axially provided with a connecting hole. An arc-shaped groove is transversely formed in the main shaft. A groove is formed in the arc-shaped groove. Threaded holes are formed in the connecting arms. The horizontal transmission shaft is formed by aluminum alloy which is composed of, by mass, 6.5-7.0% of Si, 0.35-0.8% of Mg, 0.05-0.15% of Cu, 0.08-0.17% of Fe, 0.1-0.2% of Mn, 0.05-0.08% of Zn, 0.02% or lower of Sr, 0.1-0.35% of Cr, 0.1-0.15% of Ti, 0.03% or lower of V, 0.02% or lower of Re and the balance aluminum. The invention discloses the machining method of the sewing machine horizontal transmission shaft. The production process is simple and easy to operate, and the comprehensive performance of the horizontal transmission shaft is good.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and relates to a horizontal transmission shaft of a sewing machine and a processing method thereof. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. [0003] The transmission part of the existing sewing machine is composed of components such as a frame, a hand crank or a motor. The frame is the pillar of the machine, supporting the platen and the pedals. During use, the operator steps on the pedals to drive the pulley through the crank The rotation of the chicken is driven by the belt to rotate the chicken head, and most of the hand crank or motor are directly installed on the head. ...
