Description
Technical field
The present invention relates to electric tool, specifically refer to a kind of electric saw and the two-in-one driven tool of milling cutter.
Background technology
Milling cutter is the instrument for carrying out Milling Process to workpiece, and during work, cut the surplus of workpiece by the spinning movement of cutter head, milling cutter is mainly used in the structures such as processing plane, step, groove.Electric saw is a kind of cutting tool, and the cutting on length direction is carried out in its reciprocating motion by saw blade to workpiece.
Due to the structure of milling cutter and electric saw and operation principle all not identical, therefore, in prior art, be the requirement of satisfied difference processing, these two kinds of instruments are processing factory's indispensabilities; And when go out work time, need to carry this two kinds of instruments, not only equipment investment is large simultaneously, and is inconvenient to carry.
Summary of the invention
Technical problem to be solved by this invention provides a kind of bi service electric tool driving mechanism that electric saw and milling cutter function can be combined for the present situation of prior art.
The present invention solves the problems of the technologies described above adopted technical scheme: this bi service electric tool driving mechanism, comprise drive motors, described drive motors connects power output shaft by transmission mechanism, and what it is characterized in that described drive motors can move up and down relative to casing is arranged in casing;
Described transmission mechanism comprises the first gear be connected with drive motors output shaft, second gear that can be meshed with the first gear, on described second gear, eccentric setting has the first power transmission shaft, described first power transmission shaft drives connection sliding block, described slide block connection sliding block fixed mount, be provided with bearing in slide block fixed mount, described power output shaft is spacing in the inner ring of bearing, and the outer ring of described bearing is spacing on described slide block;
Described power output shaft is also located in the centre bore of the 3rd gear, and power output shaft can move up and down relative to centre bore and can rotate with the rotation of the 3rd gear.
Drive motors can adopt various ways to move up and down, and preferably, the conveniently processing of assembling and each parts, described drive motors can be eccentrically set on motor fixing frame, and described motor fixing frame rotates and is arranged in described casing.The position of drive motors can be changed by rotary electric machine fixed mount, thus drive motors is moved up and down relative to housing.This structure also has the effect of transmission more accurate stable.
The fit structure of centre bore and power output shaft is to make the 3rd gear that power output shaft can be driven to rotate and the principle that power output shaft can move up and down relative to the 3rd gear designs, the cross section of the part that preferred described centre bore and power output shaft match with centre bore is non-circular structure, is polymorphic structure.
Compared with prior art, bi service electric tool driving mechanism provided by the present invention is by changing the meshing gear of motor-driven first gear, the saw blade and milling cutter tip linear reciprocating motion and rotation separately that are connected to same power output shaft two ends can be driven respectively, thus in an instrument, achieve the dual-use function of electric saw and milling cutter, equipment investment cost reduces, and is convenient for carrying.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figures 1 to 6, this bi service electric tool driving mechanism comprises:
Drive motors 1, eccentric is arranged on motor fixing frame 3, motor fixing frame 3 is arranged in casing 4, the spanner (not shown) be connected with motor fixing frame 3 is provided with outside casing 4, can be rotated relative in casing 4 by drive motors fixed mount 3 by operation spanner, thus change the relative position of drive motors output shaft in casing.
Transmission mechanism 5, is connected between drive motors output shaft and power output shaft 2, is delivered to power output shaft for the moment exported by drive motors.It comprises the first gear 51 be connected with drive motors output shaft, and the gear shaft 523 of second gear 52, second gear 52 that can be meshed with the first gear 51 is arranged in housing (not shown) by clutch shaft bearing 521 and axle card 522.On described second gear 52, eccentric setting has the first power transmission shaft 53, and described first power transmission shaft 53 is arranged in the chute 541 of slide block 54, drives slide block to move back and forth up and down in chute 541 while sliding.Slide block 54 connection sliding block fixed mount 56, is provided with bearing 57 in slide block fixed mount 56, power output shaft 2 is connected in the inner ring of bearing 57, and the outer ring of bearing 57 is spacing on slide block 54.This structure can make bearing moving up and down with slide block and slide block fixed mount 56, thus the power output shaft be arranged in bearing is moved back and forth up and down, and the inner ring that power output shaft can be communicated with again bearing 57 under external force simultaneously rotates relative to bearing outer ring together.
The bottom of power output shaft 2 is located in the centre bore 551 of the 3rd gear 55, and the connecting axle 552 of the 3rd gear is also arranged in housing by the second bearing 553.Centre bore 551 and power output shaft 2 match with centre bore 551 part cross section be non-circular structure, in the present embodiment, the two ends of centre bore are arc, and middle part is straight line.This structure can make power output shaft 2 can slide up and down in centre bore 551, and power output shaft 2 can be made again to rotate with the rotation of the 3rd gear 55.
Power output shaft end head is connected with the chuck 6 for clamping device head, can needs on chuck 6, connect saw blade or milling cutter tip (not shown) according to use.
The operation principle of this bi service electric tool driving mechanism is described below:
When needs make with a chainsaw function time, upwards rotating spanner, makes motor fixing frame 3 rotate relative to casing 4, thus the first gear be connected on drive motors output shaft is moved up, with the second gears meshing; Drive motors works, and is pumped by the second gear drive first power transmission shaft band movable slider and slide block fixed mount, thus drives power output shaft to pump, and completes cutting action.
When needs milling cutter works, rotate spanner, motor fixing frame drives the first gear to move down, and the first gear departs from and the engaging of the second gear, and with the 3rd gears meshing; Drive motors works, the first gear drive the 3rd pinion rotation, drives power output shaft to rotate, thus milling cutter tip is rotated, complete milling work.
