The content of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of work feed regulation machine of sewing machine
Structure, the technical problem of solution are how to make governor motion assembly and adjustment convenient.
The purpose of the present invention can be realized by following technical proposal：
A kind of work feed governor motion of sewing machine, sewing machine include casing and the main shaft being located on casing and transmission
Axle, work feed governor motion include adjustment axis and regulation connecting rod, and the adjustment axis is located on casing, fixed on the power transmission shaft to connect
Driving crank, the driving crank and regulation rod hinge connection are connected to, cam is provided with the main shaft, is arranged with the cam
Cam link, the cam link and regulation rod hinge connection, it is characterised in that one end of the regulation connecting rod is sliding end, institute
State and sliding block is hinged with sliding end, sliding groove is offered along the direction of vertical adjusting axle on the lateral surface of the adjustment axis, institute
Sliding block is stated to be embedded into sliding groove and can slide along the direction that sliding groove opens up.
The alternating amount of interior presser feet and outer presser feet is adjusted by rotating adjustment axis.Because the axis of sliding groove and adjustment axis hangs down
Directly, and the direction that opens up along sliding groove of sliding block is slided, and rotates adjustment axis, the angle of inclination of sliding groove changes, in sliding groove
Sliding block is slided and drives regulation link motion, and so as to change the rotation phase of power transmission shaft, presser feet and outer presser feet are alternately measured in realization
Regulation.During assembly and adjustment governor motion, sliding block is hinged on the sliding end of connecting rod, sliding block is then slided into sliding groove
Interior, sliding end and the adjustment axis of such connecting rod just connect.Sliding block slide into sliding groove after can again will regulation connecting rod and
