Machine tool for producing parts of flat seaming machine

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.
