Description

A kind of motor-driven puncher

Technical field: the utility model relates to a kind of paper and books punching machinery, particularly relates to a kind of motor-driven puncher.

Background technology: the puncher that uses still manually promptly utilizes lever principle mostly at present; grasp handle and drive firmly extruding punching downwards of draw point; the crude not rounding of hole mark; the hollow straight pipe cutlery punching of adopting the bottom to have cutting edge is also arranged; though hole mark polishing; but paper sheet thickness is limited; paper scrap can't be discharged in the cutlery; utility model patent 90214416.2 discloses a kind of interior chip removal sheet binding puncher with the bench drill repacking; adopt a kind of end face to have the hollow boring bit of cutting edge; extruding punching with the past; punching changes boring into; realized punching mechanization; this patent has proposed chip removal structure vertically upward; and be equipped with endoporus and core drill vertical connection in the main shaft; but in the middle of the practical application since drill bit to add the channel of chip removal of main shaft oversize; usually can take place to stop up and drilling operation continuously; and this machine can not be made a call to two holes or porous more simultaneously; the another one problem is that relatively moving between bit bore operation and drill bit and the workbench realized by artificial turning handle; labor strength is big, can't realize the automation of punching simultaneously.

Summary of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of motor-driven puncher that relatively moves and finished by machinery that can bore simultaneously between porous, the short smoothness of paper scrap channel of chip removal, drill bit and the workbench is provided.

The utility model, be achieved by following technical proposals: this motor-driven puncher comprises frame, workbench is installed on the frame, clamping has the head of drill bit, motor and electric apparatus control apparatus, motor directly or by driving-chain is connected with head inner main axis and drill bit, it is characterized in that: described head is connected with frame by special-shaped grooved rail, methods, rack is provided with T shape or the dovetail groove that is parallel to workbench on the workbench, head is provided with T shape or dovetail guide cooperates with T shape or dovetail groove, described drill bit hollow is cylindrical, its annular end face is provided with the continuous cutting edge of 360 degree, this drill bit is located at the collet clamping of spindle nose, the hypomere hollow of main shaft communicates with drill bit hollow, having breach on the main shaft cylinder is communicated with the hollow bottom, corresponding breach has installed the paper scrap outlet on the head, T-slot or dovetail groove below are provided with the scrap receiving bucket of quarrel towards the paper scrap outlet, the scrap receiving bucket below is provided with scrap storage box, link to each other by scrap leading tunnel between the two, also be provided with motor on the frame and be connected with head or workbench, drive head or workbench and move up and down by transmission device.

Compared with prior art, head is connected with frame by special-shaped grooved rail, connects reliably, and many pieces of drill bits can be set as required, realizes making simultaneously porous; Circular paper under the punch-cuts is upwards ranked from the drill bit endoporus, enters main shaft hypomere hollow bulb through collet, and the centrifugal force that the main shaft of rotation produces throws away its indentation, there from main shaft hypomere cylinder, and the paper scrap channel of chip removal is short, and the chip removal smoothness is difficult for stopping up; Also be provided with motor on the frame and be connected with head or workbench, drive head or workbench and move up and down, realized automatic punch operation by transmission device.
