Description

A kind of tapping machine

Technical field

The utility model relates to a kind of wood processing equipments, more specifically, it relates to a kind of tapping machine.

Background technique

Aperture is inevitably carried out to timber in the wood furniture manufacturing, tapping machine is commonly used in production to timber Carry out aperture.

Currently, notification number is a kind of wood drilling machine disclosed in the Chinese utility model patent of CN205112020U, it is described Workbench is rough surface, increases the frictional force of plank and work top, keeps plank more stable in process, under the drill bit Side's setting tapered bur tooth, can accelerate penetration rate, processing speed can be improved, the tapered bur tooth is detachable, the drill bit There is bolt hole in left side, and the tapered bur tooth is fixed by bolt and drill bit, after tapered bur tooth is impaired, can replace, prolong in time Stopple is arranged in long drill bit service life, the bolt hole front end.Timber is placed on work top when drilling, starting drill bit makes It is moved down, and is drilled to timber.

When timber carries out drilling processing, needs position the position of drilling, but in above-mentioned technical proposal, operator For member there is still a need for needing to measure the position punched on timber on every block of timber, punch position positioning is inconvenient, so as to cause The low problem of perforating efficiency.

Utility model content

In view of the deficienciess of the prior art, making timber aperture positioning more the utility model lies in that provide a kind of tapping machine Add conveniently, greatly accelerates the speed of aperture, improve the efficiency of aperture.

To achieve the above object, the utility model provides following technical solution: a kind of tapping machine, including workbench and solid Surely the rack being connected on workbench, the housing slide are connected with driving motor, coaxially set on the main shaft of the driving motor It is equipped with drill bit, driving wheel is rotatably connected on the work top, the workbench is equipped with the servo of driving driving wheel rotation Motor, the driving wheel contact at the surface of plank, there is with magnetic for contradicting timber vertical sliding on the workbench Limited block, by the straight line of limited block magnetic field N pole and the pole S in being vertically arranged, the workbench is located under limited block Side is equipped with coil, and the coil is electrically connected with the controller, and the workbench is equipped with the power supply powered for coil and controller, institute The direction for stating the magnetic field generated after coil is powered is opposite with the magnetic direction of limited block.

By using above-mentioned technical proposal, timber is placed on work top and starts servo motor, is using controller Coil be powered, make its generate magnetic field, because coil magnetic field direction and limited block magnetic field it is contrary, thus to limited block apply Upward magnetic force makes limited block upward sliding protrude from worktable upper surface to start the effect for contradicting timber；Using actively Wheel drives timber mobile to the side of limited block, and a side of timber is added to contact on limited block, thus drill bit and every block of wood The side of material maintains fixed distance, does not need to measure the position punched on timber, can be in the position that timber needs Aperture is set, the speed of aperture is greatly accelerated, improves the efficiency of aperture, coil stops when passing through controller after drilling It being powered, limited block sliding downwardly gravitating, to no longer contradict timber, timber slips away workbench under the action of driving wheel, from And the purpose of automatic blanking is reached, improve the working efficiency of tapping machine.
