Feeding mechanism for workpieces to be machined

The utility model relates to the technical field of workpiece machining, and discloses a feeding mechanism for workpieces to be machined. The first motor is started in the forward direction, after being started in the forward direction, the first motor can drive the threaded rod to rotate clockwise under the cooperation of the bearing, and when rotating clockwise, the threaded rod can drive the lifting plate to move upwards under the cooperation of the sliding rail and the sliding block, so that the height can be conveniently adjusted; meanwhile, by starting a second motor, the second motor can drive a reciprocating screw rod to rotate through cooperation of a bearing after being started, and the reciprocating screw rod can drive a threaded plate to reciprocate left and right through cooperation of a guide rail and a guide block during rotation; the threaded plate can drive the push plate to move together under the cooperation of the connecting piece during left-right reciprocating motion, uniform feeding of
