Abstract
The utility model provides a cutter driving structure of an electric tool. The cutter driving structure of the electric tool is simple and compact and small in peripheral size, facilities reduction of peripheral volume of the electric tool and comprises a motor (1), a speed changing box (2), a tool magazine (3) and a cutter chuck (4), wherein the motor (1) is connected with an input part of the speed changing box (2), an output part (5) of the speed changing box (2) penetrates one of cutter holes (6) of the tool magazine (3) to be peripherally in driving sleeved connection with the cutter chuck (4), and the output part (5), the cutter holes (6) and the cutter chuck (4) are located on the same axis.
Description
Technical field
The utility model relates to a kind of electric tool, is specifically a kind of cutter drives structure of electric tool.
Background technology
There is at present a kind of cutter drives structure of electric tool, it comprises motor, gearbox, tool magazine, cutter chuck, motor is connected with the input component of gearbox, the output of gearbox is connected with power transmission shaft, power transmission shaft one end enters after cutter chuck, power transmission shaft drives cutter chuck to rotate, or the output of gearbox is connected with cutter chuck, output drives cutter chuck to rotate, but no matter which kind of is, generally at output, the first gear is set, power transmission shaft or cutter chuck arrange the second gear, the first gear engages to realize with the second gear and is connected, this just makes output and cutter chuck not be positioned on same axis, simultaneously, arrange that power transmission shaft needs space, thereby cause electric tool circumferential volume larger, complex structure, compact not.
Utility model content
Technical problem to be solved in the utility model is, overcome the defect of prior art, and a kind of cutter drives structure of simple in structure, compact, electric tool that circumferential size is little is provided, and is conducive to reduce the circumferential volume of electric tool.
For solving the problems of the technologies described above, the utility model proposes a kind of cutter drives structure of electric tool, it comprises motor, gearbox, tool magazine, cutter chuck, motor is connected with the input component of gearbox, the output of described gearbox is through being socketed with the circumferential transmission of cutter chuck after one of them cutter holes of tool magazine, and described output, cutter holes, cutter chuck are positioned on same axis.
Adopt after said structure, compared with prior art, the utlity model has following advantage: owing to having saved power transmission shaft, the first gear, the second gear, and, the output of described gearbox is through being socketed with the circumferential transmission of cutter chuck after one of them cutter holes of tool magazine, described output, cutter holes, cutter chuck are positioned on same axis, so the utility model is simple in structure, compact, circumferential size is little.
As improvement, described gearbox is planet circular system gearbox, like this, the axis of planet circular system gearbox is output place axis, thereby planet circular system gearbox, cutter holes, cutter chuck are positioned on same axis, the present invention this simple in structure, compact, weight is little, working stability is reliable, is more conducive to the utility model circumferential size and reduces.
As improvement, described motor, output, cutter holes, cutter chuck are positioned on same axis, like this, are more conducive to improve the compactedness of the circumferential space layout of this utility model.
As improvement, the circumferential transmission socket of described output and cutter chuck refers to that output is polygon shaft, cutter chuck is provided with the polygonal hole coordinating with polygon shaft, described polygon shaft and polygonal hole socket, like this, simple in structure, transmission is reliable and stable, lightweight, be more conducive to the compactedness of the circumferential space layout of the utility model.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the cutter drives structure of the utility model electric tool.
As shown in the figure: 1, motor, 2, gearbox, 3, tool magazine, 4, cutter chuck, 5, output, 6, cutter holes, 7, bearing, 8, magnet.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The cutter drives structure of the utility model electric tool, it comprises motor 1, gearbox 2, tool magazine 3, cutter chuck 4, motor 1 is connected with the input component of gearbox 2, the output 5 of described gearbox 2 is socketed with the circumferential transmission of cutter chuck 4 after through one of them cutter holes 6 of tool magazine 3, and described output 5, cutter holes 6, cutter chuck 4 are positioned on same axis.
The output 5 of described gearbox 2 can push cutter chuck 4 by cutter in this cutter holes 6 while passing one of them cutter holes 6 of tool magazine 3, and in the time that output 5 drives cutter chuck 4 to rotate, cutter chuck 4 drives described cutter to rotate together.
Described output 5 ends are provided with magnet 8, magnet 8 can drive magnet 8 to return tool magazine 3 for holding cutter to realize when described output 5 exits, and tool magazine 3 is while rotating, cutter can easily be broken away from again magnet 8, certainly, other structures that can realize above-mentioned functions are also passable, and for example pick-and-place structure that is to say that described output 5 takes back cutter the structurally variable of tool magazine 3.
Described gearbox 2 is planet circular system gearbox, and described output 5 is connected with the planet carrier of planet circular system gearbox.
Described motor 1, output 5, cutter holes 6, cutter chuck 4 are positioned on same axis.
Described output 5 refers to that with the circumferential transmission socket of cutter chuck 4 output 5 is for polygon shaft, and cutter chuck 4 is provided with the polygonal hole coordinating with polygon shaft, described polygon shaft and polygonal hole socket; Cutter chuck 4 is connected with the bearing 7 of being located on the housing of electric tool.
