Description
Technical field
The utility model is related to drilling device technical fields, and in particular to a kind of novel electric hand drill.
Background technology
Common bench drill is all fixed drilling device in common bench drill and factory currently on the market, i.e., bench drill is fixed
It is used on pedestal, to increase stability, to process the workpiece that some require drilling precision high, but fixed bench drill can only be fixed and make
With cannot the same bench drill for flexibly and easily going processing large-scale cannot be processed with electric hand drill workpiece.Same electric hand drill uses
Although coming flexibly, electric hand drill can only hold manipulation, be unable to entablement brill and be accurately positioned like that, therefore easy to produce when in use
Drill bit slides, and causes pore-forming deviation too big, influences machining accuracy, while being easy to twist off drill bit.
For the low problem of traditional electric hand drill machining accuracy, number of patent application is the disclosure of the invention of CN201610695132.X
A kind of hand-free is shaken hands electric drill, including slipper, angle regulator and fixing sucking disk；The slipper includes hand
Dynamic screw rod, the horizontal connection sheet of dovetail groove, dovetail groove, motor and globe joint；The motor left and right sides is connected with and dovetail groove
Matched dovetail slide block, the downside connection drill bit or grinding wheel of motor；The horizontal connection sheet centre position of dovetail groove is equipped with diamond hole,
Activity fixing nut is set in hole, external screw thread and the traveling nut of hand screw coordinate, and hand screw turns through nut and is connected to
On the globe joint on motor top；The angle regulator includes the movable fixed structure being arranged in dovetail groove bottom end side
With the angle adjustment mechanism in the other side is set.The present invention has the following advantages：1. it is convenient, flexible, it is suitble to various working condition,
It punches accurate 2. to be widely used, is applicable to 3. hand-free of the case where bench drill can not use and holds, be not required to bore by holding manually
Hole 4. can beat the inclined hole of fixed angle.The invention has well solved the low problem of traditional electric hand drill machining accuracy, but the hair
It is bright that there are certain shortcomings：1. the invention device needs when in use if controlling motor height using hand screw
Want rotary manual screw rod that motor is made to drop to designated position, after drilling, by torque spring auto-returned, but rotation process
It wastes time, reduces processing efficiency, if without using hand screw, manually controlling motor and dropping to designated position, drill
After, need a hand to fix outside dovetail groove, another pulls dynamic motor and returns to original position, wastes time and physical, reduces
Processing efficiency；2. the invention device in boring positioning, needs artificially to estimate bit bore down position, be easy due to it is artificial because
Element generates deviation, reduces bore position precision.
In conclusion there is an urgent need for a kind of high precision machining and the convenient novel electric hand drills of manipulation.
