Technical field
The present invention relates to a kind of drilling equipment, particularly relate to a kind of small cavity drilling equipment.
Background technology
A kind of low power drilling pump of our Development and Production, cross guide plate sunk screw is connected and fixed in upper and lower guide plate seat, therefore guide plate seat needs to beat screwed hole up and down, but between upper bottom guide, cavity space is too little, cannot punch with little beakiron or little suction anvil in this short space.
Therefore, for solving the problem, spy provides a kind of new technical scheme to satisfy the demands.
Summary of the invention
The object of this invention is to provide a kind of small cavity drilling equipment.
The technical solution used in the present invention is:
Small cavity drilling equipment, this drilling equipment comprises drill bit, upper flange, lower flange, taper clamp and worm screw speed changer, described worm screw speed changer comprises decelerator casing, worm gear and worm screw, the worm gear and worm screw that cooperatively interact is provided with in described decelerator casing, described upper flange and lower flange all stretch in decelerator casing, and contact with worm gear, drill bit is fixed on auger spindle by described taper clamp, the contact position of described auger spindle and lower flange is provided with journal bearing, adjusting device is provided with bottom described lower flange, described upper flange top is provided with stud, described adjusting device matches with stud, be fixed with bottom described auger spindle and cap, described auger spindle top is provided with pressure cap, described auger spindle and pressure cap carry out relative motion by plane bearing, locating shaft is provided with bottom described plane bearing.
Further, the contact position of described upper flange and lower flange and worm gear is equipped with wear-resistant pad.
Further, described adjusting device supports cap for regulating.
Further, described auger spindle and decelerator casing upper end are located by upper flange, and described auger spindle and decelerator casing lower end are located by lower flange.
Advantage of the present invention is: simple for production, applied widely, also can punch in cylinder aperture, special-shaped aperture or small cavity, the specification of decelerator casing can be selected according to the size of die cavity, the i.e. relative position of box shape size, worm and wheel, transmit power and can add little universal joint with electric hand drill, or other slewing.
