Abstract

The utility model provides a sewing machine. According to the sewing machine provided by the utility model, moving components doing reciprocating motion along fixing tracks can be enabled to move stably, and the fixing tracks stretch along a mutual orthogonal direction of the fixing tracks. An X-axis fixing shaft is arranged under a lower shaft; an X-axis moving component has a convex shape through which a fixing platform can be supported above the lower shaft by utilizing the leg part; one side of the X-axis moving component is away from the lower shaft, and the other side of the X-axis moving component moves along the X-axis fixing shaft; a Y-axis fixing track is supported on the upper surface of the X-axis moving component; and a Y-axis moving component moves along a Y-axis fixing shaft. Therefore, according to the sewing machine provided by the utility model, the X-axis moving component can move ideally along the X-axis moving shaft, and the Y-axis moving component can be easily enabled to move stably.

Description

technical field [0001] The present invention relates to a sewing machine. Background technique [0002] The sewing machine includes a cloth feeding drive. In order to form desired stitches in the cloth, the cloth feed driving device moves the cloth in the X-axis direction and the Y-axis direction. Japanese Patent No. 3592379 discloses an XY feeding drive device of a sewing machine. The X-Y feeding drive device includes a pair of Y-axis fixed rails, a Y-axis moving component, a pair of X-axis fixed rails, an X-axis moving component, and a press table. A pair of Y-axis fixed rails are parallel to the lower shaft of the sewing machine and arranged below the lower shaft. The Y-axis moving member can move back and forth along the pair of Y-axis fixed rails. The X-axis fixed rail is fixed on the upper surface of the Y-axis moving member. The X-axis fixed rail is located between the lower shaft and the needle plate, and extends along a direction perpendicular to the Y-axis fix...
