Unless otherwise defined, all of technology used herein and scientific terminology with belong to of the present utility model
The implication that those skilled in the art are generally understood that is identical.Institute in description of the present utility model herein
The term used is intended merely to describe the purpose of specific embodiment, it is not intended that in limiting this utility model.
Term as used herein " and/or " include the arbitrary and all of one or more relevant Listed Items
Combination.
As it is shown in figure 1, a kind of electrotrephine 100 of this preferred embodiment, it is used for cutting sheet material and waits workpiece.
This electrotrephine 100 includes base plate 20, driving means 40 and cutter sweep 60.Base plate 20 is along default processing road
Footpath is moved, and driving means 40 drives cutter sweep 60 to cut to machined part.
Wherein, driving means 40 includes housing 42 and the driving structure being contained in housing 42.Housing 42
It is fixed in base plate 20.Cutter sweep 60 includes saw blade 62, the dynamic guard shield 642 covering at saw blade 62 and handle
66.Saw blade 62 is rotatably arranged in dynamic guard shield 642, and is connected with driving structure, to drive driving of structure
Cutting operation is carried out under Dong.Dynamic guard shield 642 is rotatably arranged in base plate 20, and can drive the saw blade 62 relative end
Plate 20 rotates, so that saw blade 62 can move to base plate 20 direction and make saw blade 62 may pass through base plate 20, from
And stretch in work piece.Handle 66 is connected with dynamic guard shield 642 to drive dynamic guard shield 642 to rotate.So,
The hand-holdable handle of operator 66 and drive dynamic guard shield 642 and saw blade 62 to rotate, and without hand-held complete machine housing.
Above-mentioned electrotrephine 100, is different from complete machine casing in prior art as the technology holding main handle 66
Feature, and handle 66 is located at cutter sweep 60, be not attached to driving means 40 together with, therefore grasp
Author can rotate, so that saw blade 62 is in driving means 40 with drive cutter sweep 60 by individually operated handle 66
Driving under rotate with its central axis while through base plate 20, the work piece below base plate 20 is carried out
Cutting.So, improve the handling of this electrotrephine 100, saw blade 62 can be controlled more easily and carry out
Cutting and without bearing the weight of driving means 40 simultaneously, the work for operator brings facility, be conducive to
Improve cutting accuracy.
As it is shown in figure 1, dynamic guard shield 642 one end is articulated in base plate 20, the other end can be under the drive of handle 66
Closer or far from base plate 20, the bearing of trend of handle 66 is vertical with the central axis direction of saw blade 62.So,
Referring to Fig. 2 and Fig. 3, operator, by handle 66 is applied pressure, can drive dynamic guard shield 642 to rotate,
And then drive saw blade 62 through base plate 20.Additionally, by adjusting the pressure that handle 66 is applied, adjustable
The depth of cut of saw blade 62 is to be applicable to different processing operations.Now, driving means 40 is fixed in all the time
On base plate 20, its weight is undertaken by base plate 20 completely, will not be driven when therefore operator operates handle 66
The impact of the weight of dynamic device 40, thus reduce the manipulation difficulty of this electrotrephine 100.
Refer to Fig. 1, Fig. 4 and Fig. 5, drive structure to include driving motor 442 and drive mechanism 444, drive
Galvanic electricity machine 442 connects saw blade 62 to drive saw blade 62 to rotate by drive mechanism 444.This drive mechanism 444
The outbound course of the motor output shaft 4422 driving motor 442 can be changed, dynamic by drive motor 442 to export
Power passes to saw blade 62.
Motor 442 is driven to be provided with motor output shaft 4422, the bearing of trend of motor output shaft 4422 and saw blade
The plane at 62 places is parallel, i.e. drive the motor output shaft 4422 cutting side along saw blade 62 of motor 442
To extension.So, the overall structure of this electrotrephine 100 more compact and reasonable, it is simple to this electrotrephine 100
Use and carry.
Drive mechanism 444 includes the transmission output shaft 4442 stretching out housing 42, this transmission output shaft 4442
It is perpendicular to motor output shaft 4422, drives the motor output shaft 4422 of motor 442 can drive transmission output shaft
4442.In the present embodiment, drive mechanism 444 also includes and the motor output shaft 4422 driving motor 442
The travelling gear 4444 of engagement, travelling gear 4444 is sheathed on transmission output shaft 4442 and is not arranged with flexible biography
One end of moving part 80, to drive transmission output shaft 4442 to rotate.Specifically, travelling gear 4444 is and electricity
The bevel gear that machine output shaft 4422 coordinates, this bevel gear is set on transmission output shaft 4442, thus changes
Transmission direction, makes transmission output shaft 4442 be perpendicular to drive the output shaft of motor 442.
Cutter sweep 60 includes that the saw blade axis 68 of guard shield 642 is set out in projection, and saw blade 62 is sheathed on this saw blade axis
On 68.Transmission output shaft 4442 is parallel with saw blade axis 68, and saw blade axis 68 can be driven to rotate, dynamic guard shield
The rotary middle spindle of 642 is coaxial with the rotary middle spindle of transmission output shaft 4442.Thus motor 442 will be driven
The power of output is transferred to saw blade axis 68, and then drives saw blade 62 to rotate and carry out cutting operation.
In the present embodiment, one end of transmission output shaft 4442 is with saw blade axis 68 by mediation member 80 even
Connecing, saw blade axis 68 can rotate with transmission output shaft 4442 for center of rotation, so that cutter sweep 60 drives relatively
Dynamic device 40 rotates.
Specifically, transmission output shaft 4442 and saw blade axis 68 are respectively connected with belt wheel, to be connected by transmission band.
In other embodiments, transmission output shaft 4442 engages with travelling gear respectively with saw blade axis 68.So,
Drive mechanism 444 changes the rotating speed of driving motor 442 and is transferred to cut by the power driving motor 442 to export
Cut device 60, and do not interfere saw blade 62 closer or far from base plate 20, it is achieved that driving means 40 and cutting
The separation of device 60.
Further, the rotary shaft of dynamic guard shield 642 is coaxial with the center of rotation of transmission output shaft 4442, enters one
Step makes the overall structure of this electrotrephine 100 more reasonable, compact, and reduces overall volume.
Cutter sweep 60 also includes that be rotatably connected with base plate 20 determines guard shield 644, determines guard shield 644 and is not connected with
One end of base plate 20 is inserted in dynamic guard shield 642 and is not connected with base plate 20 one end, determines guard shield 644 and dynamic guard shield 642
Relatively slide.So, can the rotation of spacing dynamic guard shield 642, make guard shield 642 rotate in the same plane.
Above-mentioned electrotrephine 100, driving means 40 is fixed on base plate 20 and separates, therefore with cutter sweep 60
In the course of processing, hold handle 66 and press down cutter sweep 60, saw blade 62 can be made quilt through base plate 20
Workpiece cuts, and cuts with drive 60 times crush-cuttings of cutter sweep without manipulating driving means 40, thus
Without bearing the weight of driving means 40, improve the handling of this electrotrephine 100, for the use of operator
Bring facility, improve the degree of accuracy of cutting.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the most right
The all possible combination of each technical characteristic in above-described embodiment is all described, but, if these skills
There is not contradiction in the combination of art feature, is all considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, its describe more concrete and
In detail, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, it is right
For those of ordinary skill in the art, without departing from the concept of the premise utility, it is also possible to do
Going out some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model is special
The protection domain of profit should be as the criterion with claims.
