Machine tool for producing parts of flat seaming machine

Abstract

The invention discloses a machine tool for producing parts of a flat seaming machine. The machine tool comprises L-shaped baffles, threaded handles, abutting plates, studs, a drill bit, a first fixing mechanism and butterfly nuts. When the machine tool for producing the parts of the flat seaming machine is used, firstly, a transmission rotating shaft blank needing to be machined is taken and placed between the L-shaped baffles and the abutting plates on a movable plate, then the butterfly nut of the first fixing mechanism is rotated, the positions of the L-shaped baffles can be adjusted through cooperation of the studs and kidney-shaped grooves, the L-shaped baffles are located under the drill bit when a transmission rotating shaft is in contact with the L-shaped baffles, then the butterfly nuts are reversely rotated, the L-shaped baffles are fixed, the operation is repeated, the L-shaped baffle of a second fixing mechanism is adjusted, then the threaded handles of the first fixing mechanism and the second fixing mechanism are sequentially rotated, under the cooperation of threaded sleeves, the threaded handles drive the abutting plates to abut against the outer side of the transmission rotating shaft, and therefore fixing of the transmission rotating shaft is completed.

Description

technical field [0001] The invention relates to the field of sewing machine production, in particular to a machine tool for producing interlock sewing machine parts. 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. And it derived art forms such as hand-push embroidery and computer embroidery. According to the purpose of the sewing machine, it can be divided into household sewing machines, industrial sewing machines and service industry sewing machines between the two; according to the driving mode, it can be divided into hand, pedal and electric sewing machines; according to the sewing stitches can be divided into Sewing machine for hand stitch, bartack stitch, single-...
