Abstract
The utility model discloses a kind of back and forth Direct Action Type electric saw, it comprises motor, housing, bearing, eccentric shaft, key, screw, planetary gear, eccentric wheel and saw blade clamping device etc.It is to drive eccentric shaft to rotate by motor by shaft coupling, then this eccentric shaft drives another eccentric shaft (being connected with the external tooth gear in planetary gear by key) to rotate by bearing, thereby the external tooth gear in drive planetary gear moves in a circle under the state engaging with internal-gear, the rotation of axle is converted into high speed linear reciprocating motion the most at last.The saw blade of the utility model electric saw moves back and forth speed and can realize by the gear number of teeth changing in planetary gear, is convenient to design and manufactures.The utility model adopts common hand hacksaw blade, uses wide, flexible.Main is to have solved the deficiencies such as electric saw noise was large in the past, cut surface is coarse, fragile.
Description
Technical field
The utility model belongs to tool-class, specifically a kind of Portable type reciprocating saw.
Background technology
Existing reciprocating saw structure is more complicated, and surface is metal chassis, and whole body volume is very large, Heavy Weight, and noise is large, fragile, carries inconvenience, and production cost is high, generally in industrial production, uses.
Summary of the invention
The purpose of this utility model, exactly in order to solve the above-mentioned technical problem existing in prior art, provides a kind of at a high speed reciprocal portable electric saw of Direct Action Type.
In order to solve the problems of the technologies described above, the utility model solves the technical scheme that its technical problem adopts: motor is connected to the left end of the first eccentric shaft by shaft coupling, the axle center of the first eccentric shaft right-hand member overlaps with the external gear center of circle, the first eccentric shaft right-hand member connects the second eccentric shaft by the 3rd positioning supports bearing, described external gear is fixed on the second eccentric shaft, under the drive of the second eccentric shaft, described external gear rotates along the internal gear being meshed with it, on the reference circle of the axle center of the second eccentric shaft in described external gear, described internal gear is fixed between the first housing and the second housing, the second eccentric shaft is connected with clamping device for saw blade by the 6th positioning supports bearing, described clamping device for saw blade is located by reciprocating linear bearing.It comprises six positioning supports bearings and an eccentric wheel, the radius length of described external gear and internal gear is than being 1:2, described the second eccentric shaft is connected by key with external gear, described the first housing and the second housing are connected by screw, described internal gear is connected with described the first housing by alignment pin, described reciprocating linear bearing can be fixed on electric saw shell, between the 4th positioning supports bearing and described external gear, be connected support with the first axle sleeve, between described external gear and eccentric wheel, be connected support with the second axle sleeve.
The beneficial effect of utility model is: because this mechanism is the linear reciprocating motion that by planetary gear, the rotation of motor is converted into saw blade, so make that mechanical operation is even, noise is little, not fragile, lightweight, and can change by changing planetary size the real work distance of saw blade, thereby obtain the electric saw of different model.
Brief description of the drawings
Accompanying drawing has provided detailed description of the invention of the present utility model, is used in the lump explaining principle of the present utility model with description.By the detailed description of doing below in conjunction with accompanying drawing, can more clearly understand the purpose of this utility model, advantage and feature, wherein identical feature is used identical label.

Detailed description of the invention
Be below the preferred example of the at a high speed reciprocal portable electric saw device of Direct Action Type of the utility model, therefore do not limit protection domain of the present utility model.
As shown in Figure 1, by shaft coupling, motor is connected with eccentric shaft (8), thereby drives eccentric shaft (8) to rotate.Eccentric shaft (8) is connected with eccentric shaft (14) by bearing (10), thereby drives eccentric shaft (14) to rotate.Eccentric shaft (8) right-hand member axle center overlaps with external gear (3) center line.External gear (3) and eccentric shaft (14) are connected for key, so external gear (3) rotates around the internal gear (4) being fixed on housing under eccentric shaft (14) drives, because the radius of gear (3) is the half of gear (4), and the axle center of eccentric shaft (14) right-hand member is positioned on the reference circle of external gear (3), thereby make the right-hand member of eccentric shaft (14) in the situation that Pivot Point Center rotates, do linear reciprocating motion.And the clamping device of saw blade (16) is located by reciprocating linear bearing (15), and be connected with eccentric shaft (14) by bearing (17), thereby finally make saw blade do linear reciprocating motion.Its middle (center) bearing (7) (9) (10) (11) (13) (17), axle sleeve (2) (5), eccentric wheel (12) and housing (1) (6) all rise respectively and support and positioning action.Eccentric shaft (14) is connected by key with external gear (3), housing (1) and housing (6) be connected by screw, internal gear (4) by alignment pin be connected with housing (1), reciprocating linear bearing (15) can be fixed on electric saw shell, be connected between support, external gear (3) and eccentric wheel (12) and be connected support with axle sleeve (5) with axle sleeve (2) between bearing (11) and external gear (3).Finally motor, housing (1) (6) and reciprocating linear bearing (15) are fixed on the main casing of electric saw.
