Machinery punching assembly

Abstract

The invention discloses a binding puncher comprising a pedestal, an elevating mechanism and a punching mechanism; the elevating mechanism comprises a hollow outer rod vertically arranged on the pedestal, an inner rod coaxially sleeved in the outer rod, and an elastic recovery piece arranged in the outer rod and abutting against the bottom of the inner rod; rollers are arranged under the pedestal; the punching mechanism comprises motors, machine boxes, and drill tools used for punching; the motor is fixed in the machine box; the machine box is fixedly connected with the inner rod; a motor shaft of the motor faces downwards, penetrates the machine box, and is in transmission connection with the drill tool; the motor shaft comprises an upper shaft and a lower shaft connected with the upper shaft through a skid mechanism; when the transmission moment between the upper and lower shafts exceeds the preset moment, the skid mechanism disconnects; the drill tool is a hollow structure; through holes matched with the drill tools are arranged on the corresponding portions of the pedestal; the pedestal is also provided with a detachable push-and-pull box connected with the through holes; the machinery punching assembly can improve work efficiency.

Description

technical field [0001] The invention relates to an office equipment, in particular to a mechanical punching assembly. Background technique [0002] The preservation and filing of paper documents requires binding, which is generally completed by a binding machine. During the binding process of the binding machine, it is necessary to use a puncher to punch holes in the paper, and then complete the pressure riveting or lead binding. At present, paper binding holes are mainly made manually. Workers place the stacked paper flat and then punch holes with a drill, which is time-consuming, laborious, inefficient, and the quality of punching is not high, so it is not suitable for occasions that require a large number of bindings; or At present, although there is also an automatic punching machine, its structure is complex, its operation is cumbersome, its practicability is not strong, and its safety is low. Contents of the invention [0003] In order to solve the above technical ...
