Abstract
The utility model relates to a hand-held electric tool used for drilling holes on reinforced concrete members, rocks, marble, brick walls, etc., which mainly solves the problems that a percussion drill is incapable in drilling large holes and in cutting reinforcing steel and cobbles and has the disadvantages of large noise, low drilling speed, etc. The utility model is mainly characterized in that a series excited motor is used for providing motive power, a secondary gear retarding mechanism is arranged in a reduction box, and a steel ball clutch for overload protection is installed on a main shaft.
Description
The utility model belongs to installs field of power tools, is used for reinforced concrete member, rock, marble and brick wall etc. are holed.
Engineering is to the boring extensive use percussion drill of above-mentioned material now, but because its boring scope is little, can not cut reinforcing bar with goose incubates stone, and the big and penetration rate of noise waits critical defect slowly, and the result is the pipeline installation more than 1 cun, and it all can't be finished.
Therefore the purpose of this utility model is: design a kind of small hand-held rig, all can drill through fast with interior above-mentioned material 4 cun, reach hand-held in light weight, 1 people can operate.
The purpose of this utility model is achieved in that the electric machine main shaft gear by after twice deceleration, is delivered to the walking gear that is loaded on the main shaft with gyration, drives main shaft, drill bit revolution by the steel ball clutch again, realizes boring.On the main shaft protecgulum, cooling water is housed and enters pipeline, directly enter drill bit internal and realize in the boring drill bit being cooled off and washing away the brill foam.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model fundamental diagram, series excitation type motor (1) shaft end gear (2) and 1 deceleration driven gear (3) interlock mutually, then by walking gear (5) on coaxial cogging (4) and the main shaft mutually interlock form the 2nd deceleration, steel ball on the steel ball clutch (6) embeds in the end face nest hole of gear (5), be equipped with cap (10) by adjusting, under the pressure of the spring (8) in being loaded on steel ball clutch main body (7) and gland (9), steel ball (6) tightly is pressed in its corresponding nest hole, and main body (7) is that key is connected with main shaft, finally make main shaft (11), drill bit (12) together turns round with the wheel in age (5) that moves about and realizes holing.The major technique feature of this structural principle is that motive power adopts series excitation type motor; after realizing twice deceleration; by the steel ball clutch gyration is reached main shaft and drill bit; the steel ball clutch is that the gyration with walking gear (5) passes to main shaft; when in case drilling torque surpasses motor load, the compression of steel ball clutch inner spring, steel ball is jumped out the nest hole of gear (5); main shaft stops revolution, and series excitation type motor has been realized overload protection.
Claims (2)
1, a kind of to reinforced concrete member, rock, the electric tool of boring such as marble and brick wall---concrete hollow bores, it is by series excitation type motor (1), 1 reduction gearing (2) and gear (3), 2 reduction gearing (4) and gear (5), steel ball clutch steel ball (6), main body (7), spring (8), gland (9) be equipped with the main body mechanism that cap (10) and main shaft (11) and synthetic diamond core bit (12) are formed, in addition with sebific duct (13), switch (14), the cooling body that protecgulum (15) is formed, its major technique feature is: motive power has adopted series excitation type motor, design has secondary garden stud wheel reducing gear in the reduction box (16), and the end of main shaft (11) is equipped with antioverloading steel ball clutch.
2, concrete hollow according to claim 1 bores; it is characterized in that: the 2nd reduction gearing (5) goes up idle running in main shaft (11); steel ball clutch main body (7) and main shaft (11) be for key is connected, and by spring (8) steel ball (6) is pressed into and forms moment of torsion transmission and antioverloading protection mechanism in its corresponding nest hole.
