Description
Technical field
The utility model is related to machining tools arts, specially electrodynamic type rocker concentric holes boring grab.
Background technology
The characteristics of boring grab refers to the holding appliance being processed to workpiece on drilling machine, drill jig is generally being bored
Hole machined is carried out to workpiece on bed, is had the characteristics that following more：(1) rigidity of cutter itself is poor：The hole processed on drilling machine is more
For the hole of small-medium size, process content nothing more than processing such as brill, expansion, hinge, ream or tappings, so, cutter diameter often compared with
It is small, and axial dimension is larger, the rigidity of cutter is poor.(2) asymmetry of multi-blade easily causes the Form and position error in hole：Bore,
Expand, the aperture knife tools, mostly multiple-cutting-edge tool such as hinge, when to be distributed asymmetric or edge length unequal for blade, can cause to be processed
The foozle in hole, in particular by common Twist Drill, the asymmetry of the both sides blade caused by hand grinding drill bit, pole
The hole position offset in processed hole, the bending of aperture increases and axially bored line and crooked are easily caused, shape, the position essence in hole are seriously affected
Degree.(3) when common spiral bit pulls out of hole, hole position precision is very poor：Common fluted drill axial dimension is big, poor structure rigidity, in addition boring
Cored structure is formed by chisel edge, destroys centering, keeps apex point movement unstable, and larger hole position is often caused during playing cobalt accidentally
Difference.
In single-piece, small lot production, often operative employee to be leaned on constantly to carry out manual synchronizing control in trip-out process
Hole position precision, and in high-volume efficiently production, then it needs to solve the stringent guiding of cutter by the improvement and fixture of edge structure
Certainly.In the production of machine tool, there is presently no a kind of electrodynamic type rocker concentric holes boring grabs easy to process.
Utility model content
The utility model is exactly in view of the above problems, provide a kind of concentric hole drilling folder of electrodynamic type rocker easy to process
Tool.
The utility model is achieved through the following technical solutions above-mentioned purpose：
Electrodynamic type rocker concentric holes boring grab, including left-handed screw nut, left screw rod, pedestal, bushing plate, pressing plate, location hole, electricity
Machine, standing screw, it is characterised in that left-handed screw nut is located on left screw rod and is connected with bushing plate across left pressing plate and extends to fixation
On screw rod, location hole is located at bushing plate right center and opposite with right pressing plate, and pedestal is L-shaped, and most lower positioned at total
It is closely joined together below Fang Bingyu pressing plates, motor setting is connected with the top of L-type pedestal, motor output end with bushing plate
It connects.Left-handed screw nut and left screw rod all there are two, motor and have screw rod also all there are two, pressing plate have two pieces respectively in the left and right sides, it is fixed
Position hole shows groove shapes.
In the utility model, by the way that processing part is put into model, both sides rotate left-handed screw nut and motor, left screw rod simultaneously
Left and right sides pressing plate can be made constantly to clamp bushing plate by the effect of left-handed screw nut and motor with standing screw, while needing to process
Part be secured firmly on bushing plate, location hole works according to the size that regulates, and the utility model may be implemented
The effect clamped is reinforced, and by the way that bushing plate to be connect with motor output end, directly bushing plate can be driven to move by motor
It is dynamic.
Description of the drawings
Fig. 1 be the utility model overall structure diagram wherein：
1-left-handed screw nut, 2-left screw rods, 3-pedestals, 4-bushing plates, 5-pressing plates, 6-location holes, 7-motors, Gu 8-
Determine screw rod.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Electrodynamic type rocker concentric holes boring grab, including left-handed screw nut 1, left screw rod 2, pedestal 3, bushing plate 4, pressing plate 5, positioning
Hole 6, motor 7, standing screw 8, it is characterised in that left-handed screw nut 1 is located on left screw rod 2 and is connected with bushing plate 4 across left pressing plate 5,
And extend on standing screw 8, location hole 6 is located at 4 right center of bushing plate and opposite with right pressing plate 5, and pedestal 3 is L-shaped, and
It is closely joined together positioned at total bottom and with 5 lower section of pressing plate, the setting of motor 7 is with the top of L-type pedestal 3, electricity
7 output end of machine is connect with bushing plate 4.Left-handed screw nut 1 and left screw rod 2 all there are two, motor 7 and have screw rod also all there are two, pressing plate 5
There are two pieces respectively in the left and right sides, location hole 6 shows groove shapes.
In the utility model, by the way that processing part is put into model, both sides rotate left-handed screw nut 1 and motor 7, left spiral shell simultaneously
Bar 2 and standing screw 8 can make left and right sides pressing plate 5 constantly clamp bushing plate 4, while handle by the effect of left-handed screw nut 1 and motor 7
The part processed is needed to be secured firmly on bushing plate 4, location hole 6 works according to the size regulated, this practicality is new
Type may be implemented to reinforce the effect clamped, and by the way that bushing plate 4 to be connect with 7 output end of motor, can directly pass through motor 7
Bushing plate 4 is driven to move.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
