Abstract

The invention discloses a swing device capable of automatically resetting. The swing device capable of automatically resetting solves the problem in the prior art that the efficiency is low when sheets are pressed manually, and comprises a machine frame, a first fixing plate connected with the machine frame, a second fixing plate connected with the machine frame, a driving gear connected with the first fixing plate in a rotary mode, a transmission gear meshed with the driving gear, a rotation arm coaxially fixed with the transmission gear, a swing arm and a limiting block fixed to the second fixing plate, wherein the middle of the swing arm is hinged to the second fixing plate, the upper end of the swing arm makes contact with one end of the rotation arm, the lower end of the swing arm is working end, a connecting pin pillar is arranged between the middle and the upper end of the swing arm, and a spring of the connecting pin pillar is further arranged on the second fixing plate. The swing device capable of automatically resetting is simple in structure and enables the swing arm to freely move back and forth.

Description

technical field [0001] The invention relates to the technical field of reciprocating motion, in particular to an automatic reset swing device. Background technique [0002] In the existing mechanical transmission device, in order to convert circular motion into reciprocating motion, a coaxial peach-shaped cam is usually set on the rotating shaft: that is, the cam drive uses the protruding part of the peach tip to push out the swing arm, so that The circular motion of the cam drive is converted into the linear motion of the swing arm. Taking a known cam drive (Chinese patent CN89211301.4) as an example, its shortcoming is: after the peach-shaped cam pushes out the swing arm, the swing arm in this device can only There is no reciprocation, and the swing arm cannot automatically reciprocate mechanically. Contents of the invention [0003] The present invention intends to provide an automatic reset swinging device to solve the problem that the swinging arm of the cam transmi...
