Description
Technical field
The invention belongs to the technical fields of boring bar tool, specifically disclose a kind of power drill convenient for accurate positionin.
Background technique
Power drill, also known as electric hand drill are a kind of tools for drillings such as metal material, timber, plastics.When equipped with positive and negative
After turning first switch and electrically-actuated throttle device, it can be used to make electric screwdriver.Some models are furnished with rechargeable battery, can be in certain time
It is interior, it is worked normally in the case where no external power supply.Currently, the power drill generally used in the market includes drill bit, auger spindle, machine
Body, first switch, motor etc..Operator generally can first be drawn on workpiece to be processed when being drilled using power drill
Then the position of good prebored hole holds power drill again and drills, but in the process, if operator's misoperation meeting
Cause drill bit that can not be perpendicularly inserted into workpiece, when especially workpiece itself has certain tilt angle, operator is less
Easily keep drill bit vertical with workpiece, this will lead to the hole inclination drilled out, not be available.
Summary of the invention
The purpose of the present invention is to provide a kind of power drills convenient for accurate positionin to bore when solving operator's drilling
Head is easy inclination and is inserted into the problems in workpiece.
In order to achieve the above object, base case of the invention are as follows: convenient for the power drill of accurate positionin, including be arranged in machine
Auger spindle, first switch, motor and power supply inside body, the first switch, motor and power supply form closed circuit, auger spindle and electricity
The output end of machine is coaxially connected, and the auger spindle is equipped with drill bit, and drill bit is located at the outside of fuselage, and the circumferential direction of the fuselage is equipped with
At least three sliding bars, the sliding bar are slidably connected on fuselage and parallel with drill bit, and the circumferential direction of the fuselage is equipped with close
The holding shell of the annular of envelope, the sliding bar are passed through and are slidably and sealingly connected on holding shell, be fixed in the holding shell
The quantity of first piston cylinder and second piston cylinder, the first piston cylinder is identical as sliding bar, the volume of the second piston cylinder
Equal to the sum of the volume of all first piston cylinders, first piston, a first piston have been slidably and sealingly connected in first piston cylinder
Affixed with a sliding bar, one end on the first piston cylinder far from sliding bar is communicated with air inlet pipe, and all air inlet pipe are separate
One end of sliding bar is connected to second piston cylinder, has been slidably and sealingly connected with second piston in the second piston cylinder, and described
One end on two pistons far from air inlet pipe is equipped with piston rod；Induction mechanism, the induction mechanism packet are additionally provided in the holding shell
Pedestal, sliding block, fixed block, positive plate and negative plate are included, the pedestal is fixedly installed in holding shell, and the fixed block is fixedly connected
On pedestal, the sliding block is slidably connected on pedestal, and the sliding block and piston rod are affixed, and the positive plate is fixed at cunning
On block, the negative plate is fixed on fixed block, and the positive plate and negative plate are connected on first switch, motor and power supply
Circuit in, the distance between positive plate and negative plate be equal to second piston cylinder length.
The working principle of this base case is: when operator uses power drill, first by the table of sliding bar alignment pieces
Face, and drill bit is made to be directed at hole to be processed, power drill then is pushed to the direction of workpiece, sliding bar gradually pushes first to live at this time
Gas in first piston cylinder is pushed into second piston cylinder by plug, first piston from air inlet pipe, and second piston band piston
Bar, sliding block and positive plate are close to negative plate, since the volume of second piston cylinder is equal to the sum of the volume of all first piston cylinders, and
The distance between positive plate and negative plate are equal to the length of second piston cylinder, so when the gas in all first piston cylinders is whole
After entering second piston cylinder, the mobile distance of second piston is equal to the length of second piston cylinder, at this time positive plate and negative plate
It is in contact, then operator presses first switch again, and the output end of motor drives drill bit rotation, it will be able to bore to workpiece
Hole.Three points can position a face, so when positive plate and negative plate contact, the table of three sliding bars and drill bit and workpiece
All in orthogonal state, drill bit would not run-off the straight when being drilled in face.
The beneficial effect of this base case is: only when drill bit is vertical with workpiece surface in 1. this programme, and sliding bar
When first piston being driven to be moved to the inner terminal of first piston cylinder, first switch can control electric motor starting, so drill bit exists
When drilling, drill bit is always orthogonal with workpiece surface.Meanwhile sliding bar, when not occurring mobile, switch is unable to control electricity
Machine starting, so maloperation can be prevented and lead to injury to personnel.2. operator is when using power drill, sliding bar and workpiece
Surface offsets, so sliding bar can play shockproof effect when power drill generates vibration, reduces vibration to the shadow of operator
It rings.
Further, the sliding bar includes fixed outer bar and flexible interior bar, and the fixed outer bar uses non-magnetic material
It is made, fixed outer bar is slidably located in flexible interior bar, and the outer wall of fixed outer bar is equipped with driving lever and can attract the electricity of flexible interior bar
The outer wall of magnet, the holding shell is equipped with second switch, and second switch is electrically connected with electromagnet, and second switch can be by driving lever
Stir opening and closing.Electromagnet is in the state being electrified for a long time, and it can fix flexible interior bar.In operator will stretch
The surface of bar and workpiece offsets, and when pushing power drill, and driving lever can move closer to and stir second switch, second switch control electricity
Magnet is closed, and interior bar of stretching at this time can be slided in fixed outer bar, so interior bar of stretching is not when drill bit gradually gos deep into workpiece
It can stop drill bit in the axial direction of drill bit.
Further, the pedestal, sliding block, fixed block and piston rod are all made of glass and are made.Using this programme, glass is not led
Electricity, so pedestal, sliding block and fixed block will not all have an impact electric power loop.
Further, one end on the sliding bar far from holding shell is equipped with resilient suction cups.Using this programme, work as resilient suction cups
When contacting with the surface of workpiece, resilient suction cups can be such that sliding bar is temporarily fixed on workpiece surface, prevent sliding bar shake and
It moves horizontally, so operator is in drilling, sucker can further function as the effect of damping.
Further, the both ends of the first piston cylinder and the both ends of second piston cylinder are equipped with limited block.Using this programme,
It can prevent first piston from skidding off first piston cylinder, second piston skids off second piston cylinder.
Further, the fuselage is equipped with the spring that fixed outer bar can be made to reset.Using this programme, when drilling is completed
Afterwards, power drill leaves workpiece, and spring drives fixed outer bar, first piston, second piston to reset.
