Background technology
Conventional electric circular saw can only be installed a saw blade, and cutting efficiency is low in actual mechanical process, uses relatively effort; After adopting two saw blade rotating synchronous cutting devices, greatly improved cutting efficiency, and used very light.
A kind of rotating cutting machine of Chinese patent double saw blade device of finding the patent No. in addition and being CN200520069542.0 discloses a kind of rotating cutting machine double saw blade device, this utility model is in it comprises, outer frame, in being located at, saw blade on the outer frame, in, outer frame with in, outer saw blade connects respectively and is an integral body, this utility model because in, outer frame is connected with saw blade and is an integral body, and the end face of its contact is an inverted cone surface, two saw blade applying degree of the positive cutting machine of the fine adjustment of energy, form between two saw blades to press close to mutually, especially saw blade outer rim saw blade cutter tooth position, be close to mutually, make cutting more laborsaving, joint-cutting is neat, interior, the ring-type position that outer saw blade is adjacent to mutually scribbles the face coat of lubricant effect, when two saw blades closely are adjacent to the normal cutting in back, the power of reducing friction is guaranteed two saw blades energy operate as normal of forward and reverse rotation cutting.But because two saw blades can not the self adaptation adjusting play after adjusting,, produce wearing and tearing, require further improvement so make two saw blades produce collision and friction easily.
Summary of the invention
The utility model provides a kind of electric circular saw for solving the problems of the technologies described above, adopt two saw blade rotating synchronous cutting devices after, greatly improved cutting efficiency, use very light, and simple in structure.
The utility model for the technical scheme that provides is provided is: a kind of electric circular saw, comprise motor, saw blade, output shaft, casing, and it is characterized in that:
Output bevel gear is installed on the output of motor;
First conical gear is fixed on the lower end of output shaft, meshes with output bevel gear to drive output shaft and rotate to a direction;
Outer saw blade is built in the middle of train wheel bridge and the interior chuck down, is fixed on the other end of output shaft;
Second conical gear is installed in rotation on the output shaft by bearing, makes second conical gear produce opposite motion with the output bevel gear engagement;
Outer chuck down is connected the position, upper end of second conical gear, and descends chuck to be fixed in the casing by bearing outward;
Interior saw blade is installed on the step surface of outer chuck upper end down movably.
As improvement, described output shaft lower end is equipped with a flat key and is installed in rotation in the casing by bearing.
As improvement, described outer chuck down is connected by screw thread with second conical gear upper end.
As improvement, described outer chuck down is installed in rotation on the upper end of output shaft, the porose back-up ring of using of liner by bearing.
As improvement, described outer chuck periphery down is installed on the bearing block by bearing, in be lined with dust ring, bearing block is connected on the support of casing by screw.
As improvement, the output of described motor is equipped with air-cooled impeller in the sidepiece cavity of casing.
Compared with prior art, advantage of the present utility model is: after adopting two saw blade rotating synchronous cutting devices, greatly improved cutting efficiency, and use very light, operate comfortable, adopt suitable transmission mechanism and interior freely saw blade mounting structure, simplified structure makes structure more reasonable and practical.
Description of drawings
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is the utility model STRUCTURE DECOMPOSITION figure.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1: a kind of electric circular saw, comprise motor 1, saw blade 18,20, output shaft 7, casing 2, output bevel gear 22 is rotatably connected on the output of motor 1 by the bearing 23 that is installed in the bearing groove, and the output of motor 1 is equipped with air-cooled impeller 24 in the sidepiece cavity of casing; First conical gear 5 is fixed on the lower end of output shaft 7, carries out axial location by axle with ring washer 4 and cooperates, and make first conical gear 5 and output bevel gear 22 engagements, drives output shaft 7 and rotates to a direction; Output shaft 7 is installed in rotation in the casing 2 by bearing 3, and output shaft 7 lower ends are equipped with a flat key 6 and fix first conical gear 5, and output bevel gear 22 drives the rotation of output shaft 7, is the rotation that drives first conical gear 5 by flat key 6; Second conical gear 9 is installed in rotation on the output shaft 7 by bearing 8, make second conical gear 9 produce opposite motion with output bevel gear 22 engagements, the upper end of second conical gear 9 is connected with outer chuck 15 down by engage thread, outer chuck 15 down is rotatably mounted on the bearing block 13 that is fixed in the casing 2 by bearing 10, bearing block 13 covers descend chuck 15 peripheries outside, in be lined with dust ring 12 and prevent that entering of dust and hole are with ring washer 11, and bearing 10 is arranged on bearing block 13 and descends outward between the chuck 15, bearing block 13 is connected by screw 14 on the support of casing 2, and bearing block 13 and support have been formed complete casing 2 like this; Outer chuck 15 down also is installed in rotation on the upper end of output shaft 7 by bearing 16, liner is porose with ring washer 17; Interior chuck 19 down is arranged on and carries out size cooperation installation between outer chuck 15 down and the output shaft 7, and reciprocatable rotation is rotated; The outer upper surface of chuck 15 down forms step surface 25, and interior saw blade 18 is installed on the step surface 25 of outer chuck 15 upper ends down movably; Outer saw blade 20 is built in the middle of train wheel bridge 21 and the interior chuck 19 down, is fixed on the other end of output shaft 7 by screw, between interior like this saw blade 18 spacing saw blades outside 20 and the step surface 25, can suitably slide.
