Row description.
In order to thoroughly understand the present invention, detailed step and detailed structure will be proposed in following description, so as to
Explain technical scheme.Presently preferred embodiments of the present invention is described in detail as follows, but in addition to these detailed descriptions, this
Invention can also have other embodiment.
The invention provides a kind of knocking drilling tool 10, including：
Outer cylinder body 7, the outer cylinder body 7 are hollow, and the inwall of outer cylinder body 7 is provided with some tracks 12, each phase of track 12
Mutually it be arranged in parallel and is located in a spiral manner on the inwall of the outer cylinder body 7 from top to bottom；
Central rotating body 11, it is arranged in the outer cylinder body 7, the top and bottom of central rotating body 11 are respectively by described outer
Opening at the upper and lower ends center of cylinder 7 is exposed, and the top of central rotating body 11 is provided with percussion portion 1, and bottom is provided with drill bit 10,
Some turning arms 4 are provided with the middle part of central rotating body 11, the end of the turning arm 4 is provided with ball 5, each ball
5 are arranged respectively in a track 12 and can be slided in track 12.
In an optional embodiment of the invention, the upper and lower ends of the outer cylinder body 7 are provided with closure 3, described close
Capping 3 is reserved with for the exposed centre bore of the upper and lower ends of central rotating body 11, and locating ring 2 is provided with the centre bore.This is fixed
Position ring 2 can not produce horizontal movement for limiting central rotating body 11, ensure the stability in drilling process.Further, institute
Closure 3 can be screwed in by way of screw thread the upper and lower ends of outer cylinder body 7 by stating closure 3, can also directly pass through screw
It is fixed on outer cylinder body 7.
In an optional embodiment of the invention, some support feets are provided with below the closure of the bottom of outer cylinder body 7
9, the drill bit is fixed on by the support feet 9 to be drilled on object.In order to further increase support feet 9 and be drilled object it
Between contact area, we can be provided with 90 ° of kink 9a in the bottom of support feet 9, to improve stablizing effect.
In an optional embodiment of the invention, plane bearing 6 is provided with the outer cylinder body 7, the plane bearing 6 is set
Put below the turning arm 4.Further, in the outer cylinder body 7 and the plane bearing and the bottom of outer cylinder body 7 it
Between be additionally provided with spring 8.
In an optional embodiment of the invention, 3 parallel downward tracks 12 are provided with the inwall of outer cylinder body 7,
And the middle part of central rotating body 11 is provided with 3 turning arms 4, the line of each end of turning arm 4 is equilateral triangle.Using
This arrangement mode, overall structure stability are stronger.
In an optional embodiment of the invention, the length of central rotating body 11 positioned at the lower section of turning arm 4 is less than institute
Central rotating body 11 length of the rheme above the turning arm 4, i.e., no matter turning arm 4 is rotated to any position in outer cylinder body bottom
Locate, the percussion portion at the top of closure is in exposed state.
In an optional embodiment of the invention, the width in the percussion portion 1 is more than the rotating shaft of the central rotating body 11
Partial width, to increase percussion area, us are facilitated preferably to tap.
In an optional embodiment of the invention, the drill bit 10 and the Integral design of central rotating body 11 or replaceable
Disassembly design.When using the scheme of the replaceable disassembly design of drill bit, it would be desirable to open up drill bit in the bottom of central rotating body 1
Groove, according to the demand of drilling, the drill bit of dimension is fixed in drill trough by we.
During percussion, often tap once, central rotation is known from experience to be travelled downwardly in the presence of hammer, is revolved with center
Turn the pivot arm ends of one ball can slide downward in orbit, the linear downward motion of central rotating body is changed into
Downward spiral is moved, so as to drilling operation.Often tap once simultaneously after, turning arm is transported upwards in the presence of bottom spring 8
Dynamic to keep in the center, operator carries out reciprocal beat to ultimately form expected drilling stroke.If there is no plane bearing 6, rotation
Arm 4 is very big by the friction from spring 8 in rotation process, therefore we set up one between turning arm 4 and spring 8
Plane bearing 6, solves the problem well.
In summary, due to present invention employs above-mentioned technical scheme, by the continuous percussion to percussion portion, by rotation
Operation of the ball of pivoted arm end in helical orbit, the active force tapped downwards is changed into the motion of drill bit downward spiral,
