Because structure and the operation principle of milling cutter and electric saw are all not identical, therefore, in prior art, for meeting the requirement of different processing, these two kinds of instruments are processing factory's indispensabilities; And when going out work, need to carry this two kinds of instruments simultaneously, not only equipment investment is large, and is inconvenient to carry.
Summary of the invention
Technical problem to be solved in the utility model is that the present situation for prior art provides a kind of bi service electric tool driving mechanism that electric saw and milling cutter function can be combined.
The utility model 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 with respect to casing is arranged in casing;
Described transmission mechanism comprises the first gear being connected with drive motors output shaft, second gear that can be meshed with the first gear, on described the second gear, eccentric setting has the first power transmission shaft, described the first power transmission shaft drives connection sliding block, described slide block connection sliding block fixed mount, in slide block fixed mount, be provided with bearing, 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 and can rotate with the rotation of the 3rd gear with respect to centre bore.
Drive motors can adopt various ways to move up and down, and preferably, for convenient for assembly and processing 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.By rotary electric machine fixed mount, can change the position of drive motors, thereby drive motors is moved up and down with respect to housing.This structure also has the more effect of accurate stable of transmission.
The fit structure of centre bore and power output shaft is so that the 3rd gear can drive the principle design that power output shaft rotates and power output shaft can move up and down with respect to the 3rd gear, 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 utility model is by changing the meshing gear of motor-driven the first gear, can drive respectively the saw blade and milling cutter tip linear reciprocating motion and the rotation separately that are connected to same power output shaft two ends, thereby in an instrument, realized the dual-use function of electric saw and milling cutter, equipment investment cost reduces, and is convenient for carrying.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
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 outer spanner (not shown) being connected with motor fixing frame 3 that is provided with of casing 4, by operation spanner, can with respect to casing 4, rotate by drive motors fixed mount 3, thereby 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, for the moment of drive motors output is delivered to power output shaft.It comprises the first gear 51 being connected with drive motors output shaft, and the gear shaft 523 of second gear 52, the second gears 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 the second gear 52, eccentric setting has the first power transmission shaft 53, and described the first power transmission shaft 53 is arranged in the chute 541 of slide block 54, in the interior slip of chute 541, drives slide block to move back and forth up and down.Slide block 54 connection sliding block fixed mounts 56, are 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 with the moving up and down of slide block and slide block fixed mount 56, thereby the power output shaft that makes to be arranged in bearing moves 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 with respect 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, middle part is straight line.This structure can make power output shaft 2 in centre bore 551, slide up and down, and can make again power output shaft 2 rotate with the rotation of the 3rd gear 55.
On power output shaft termination, be connected with the chuck 6 for clamping device head, can need on chuck 6, connect saw blade or milling cutter tip (not shown) according to using.
The operation principle of this bi service electric tool driving mechanism is described below:
When needs make with a chainsaw function, upwards rotating spanner, motor fixing frame 3 is rotated with respect to casing 4, thereby the first gear that makes to be connected on drive motors output shaft moves up, with the second gear engagement; Drive motors work, pumps by second gear drive the first power transmission shaft band movable slider and slide block fixed mount, thereby drives power output shaft to pump, and completes cutting action.
When needs milling cutter is worked, rotate spanner, motor fixing frame drives the first gear to move down, and the first gear departs from the engagement with the second gear, and meshes with the 3rd gear; Drive motors work, the first gear drive the 3rd gear rotates, and drives power output shaft to rotate, thereby milling cutter tip is rotated, and completes milling work.
