Abstract

The invention discloses a slider balance mechanism for a full servo notching machine, comprising a notching machine body. The notching machine body is provided with an AC servo motor and a slider. The output shaft of the AC servo motor is connected with an eccentric crank shaft which is provided with the slider through a coupler. The notching machine body is provided with a balance member which is connected with a connecting rod block through a swinging shaft, the lower end of the connecting rod block is connected with a connecting rod through a small shaft, and the lower end of the connecting rod is fixedly arranged on the slider. The slider balance mechanism is compact in structure, wherein the inertia force of the slider in movement is eliminated, the body vibration is reduced, the notching noise is reduced, die wear is reduced, the frequency stroke of the slider is greatly improved, production efficiency is increased and the punching accuracy is improved.

Description

technical field [0001] The invention relates to the field of notching machines for motor iron chip processing equipment, in particular to a sliding block balance mechanism used on full-servo notching machines. Background technique [0002] The punching machine is a special equipment for single-slot punching used for punching the slot holes of the motor rotor or stator core. The punching die for punching the motor rotor or stator core sheet is installed between the punch (slider) and the worktable, and the upper die is driven to reciprocate up and down through the up and down reciprocating movement of the punch (slider). The iron chips (punches) that need to be punched are installed on the indexing device with intermittent movement, and the iron chips (punches) are indexed according to the preset intermittent movement requirements through the indexing device. When the punch (slider) moves downward, the iron chip (punch) does not rotate and waits for the punching groove. When...
