Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1-2, a high-precision positioning and punching electric hand drill, which comprises a clamping handle 1, a positioning pressing plate 2 is fixedly installed on the side surface of the clamping handle 1, a fixed support 3 is arranged on the top end of the clamping handle 1, the left end of the fixed support 3 is fixedly connected with the top of the right side of the clamping handle 1, a connecting slide block 4 is connected with the outer surface of the fixed support 3 in a clamping manner, the top of the connecting slide block 4 is in threaded connection with an electric hand drill 5, a transmission screw 6 is arranged inside the fixed support 3, the outer surface of the transmission screw 6 is in transmission connection with the inside of the connecting slide block 4 through a transmission slide block 7, one end of the transmission screw 6 is movably sleeved with one side of the inner cavity of the fixed support 3, and the other end of the transmission screw 6 is in.
Wherein, to the setting of positioning pressure plate 2 and fixed bolster 3, can carry out accurate vertical location operation to electric hand drill 5, make its in-process in drilling can not appear the problem of slope about, and then cause the straightness that hangs down of hole site higher, accurate nature is better, makes the drill bit can only receive perpendicular pressure inwards moreover, and is higher to the protectiveness of drill bit, can not lead to its problem of appearing damaging because of the atress is inhomogeneous at the in-process of drilling, the effectual practicality and the reliability that improve this electric hand drill.
Among this technical scheme, mutual welding and formation "L" type structure between centre gripping handle 1, location clamp plate 2 and the fixed bolster 3, and be equipped with driving motor 8's rotational speed control switch in centre gripping handle 1's inside.
Wherein, to centre gripping handle 1, become the setting of "L" type structure between positioning pressure plate 2 and the fixed bolster 3, when the device is handed to the right hand and the material of extrusion by drilling, the stability of structure is higher, fix a position more accurately, utilize the rotational speed control switch in the centre gripping handle 1 to adjust electric hand drill 5's feed speed simultaneously, and the rotational speed of holding electric hand drill 5 and controlling it is held up to the cooperation left hand, the mutually supporting of left and right hand, make the design of this electric hand drill use more humanized, control more nimble convenience, stability and security are higher at the in-process that uses this electric hand drill.
In this technical scheme, the swallow-tail type spout has all been seted up to both sides around the fixed bolster 3 surface, and slides the joint between fixed bolster 3 and the link block 4.
Wherein, the setting to dovetail spout around fixed bolster 3 for the precision when link block 4 makes a round trip to slide on fixed bolster 3 is higher, has improved wearing and tearing and bearing capacity between fixed bolster 3 and the link block 4, and at long-term in-process that makes a round trip to wear, excessive wearing and tearing can not appear and lead to the relatively poor problem of sliding positioning of electric hand drill 5, have guaranteed its life when keeping this electric hand drill work precision.
In the technical scheme, the maximum movable stroke of the connecting slide block 4 on the fixed support 3 is larger than the total length of the electric hand drill 5 after clamping the drill bit.
Wherein, to the setting of the biggest movable stroke of connecting block 4 and electric hand drill 5 length for electric hand drill 5 has sufficient side to side gliding space on fixed bolster 3, makes its total length can not exceed the left side of location clamp plate 2 after the installation drill bit, and then makes the laminating that location clamp plate 2 can be inseparable on the material by the drilling, can not appear the phenomenon that the top of location clamp plate 2 was jacked up because of the drill bit overlength.
The use method and the working principle of the embodiment are as follows:
Firstly, a drill bit on an electric hand drill 5 is changed into a required specification and model, then a right hand holds a clamping handle 1 to tightly attach a positioning pressing plate 2 to the surface of a material, and simultaneously holds the position of the rear half part of the electric hand drill 5 by utilizing the action, then a rotating speed control switch on the clamping handle 1 is pressed, a driving motor 8 is started to drive a transmission screw 6 to rotate and slowly align the top ends of the connecting slide block 4, the electric hand drill 5 and the drill bit on the electric hand drill 5 to the position needing drilling under the screw transmission action of a transmission slide block 7, then the left hand is used to stir the starting switch on the electric hand drill 5 to drive the drill bit on the electric hand drill to rotate at high speed, simultaneously the rotating speed control switch on the clamping handle 1 is adjusted to drive the electric hand drill 5 to slowly move inwards to realize the drilling operation, and the electric hand drill 5 always moves horizontally on a fixed support 3 in, the phenomenon of action slope can not appear, the effectual precision that has improved this electric hand drill location of punching.
