Said guide device includes roller and supporting mechanism connected with roller and baseplate, said supporting mechanism includes at least an elastic element. When the roller is pressed, the elastic deformation of said elastic element can make the central shaft of roller be moved relatively to said baseplate.
Description
Technical field
The present invention relates to a kind of electric circular saw, especially a kind of base plate has the electric circular saw of guider.
Background technology
Use electric circular saw to workpiece process in, usually the base plate with electric circular saw is placed on the workpiece, the operator promotes the electric circular saw cut workpiece forward, owing to the force of sliding friction acting that in use will overcome base plate bottom surface and workpiece all the time makes the operator very easily tired, and can be usually because the feasible cutting of the error of operation offset direction.United States Patent (USP) 5056499 has disclosed the guider on a kind of cutting machine that is used to cut cement, it is by roller is installed on base plate, reach the purpose of guiding, but because roller all is positioned at the same side of saw blade, making cutting machine turn on one's side easily is thereby that the relative cement face tilt in its base plate bottom surface influences cut quality, it is provided with supporting bracket at the opposite side of saw blade in order to prevent the cutting machine rollover, yet, thereby make the easy offset direction of cutting influence guide effect because supporting bracket is different with the frictional force that roller is subjected to.
Summary of the invention
Technical problem to be solved by this invention is: a kind of electric circular saw that has guider is provided, has solved when guaranteeing guide effect because the problem of the not parallel surface of the work of base plate that installation of guiding device causes.
Technical scheme of the present invention is: a kind of electric circular saw, comprise fuselage, base plate and be installed at least one roller on the base plate, fuselage comprises motor and by motor-driven saw blade, wherein electric circular saw also comprises the supporting mechanism that connects roller and base plate, supporting mechanism comprises at least one flexible member, when the roller pressurized, the flexible member strain makes the central shaft of roller move relative to base plate, and total elastic force of described flexible member is suitable with the weight of described fuselage and described base plate.
Electric circular saw of the present invention has reduced the frictional force of cut direction because of having adopted guider, increase side-friction and made the operation more laborsaving and easier cutting straight line of electric circular saw, and owing to used flexible member in the guider, make guider to move relative to base plate, the height that has reduced base plate bottom surface and surface of the work in the use of electric circular saw makes it to be difficult for rollover, thereby has guaranteed cut quality.

The specific embodiment
Shown in seeing figures.1.and.2, in the present invention's first preferred embodiment, a kind of electric circular saw comprises fuselage 1, base plate 2 and be installed in two guiders 3 on the base plate 2.Fuselage 1 comprises the saw blade 11 that is driven rotation by motor (not shown).Base plate 2 comprises the base plate bottom surface 21 and through hole 22,23 (see figure 3)s that can be placed on surface of the work.Guider 3 comprises roller 4 and two supporting mechanisms 5 that connect roller 4 and base plate 2.
With reference to Fig. 3 and shown in Figure 4, in the present invention's first preferred embodiment, roller 4 comprises the extended axle journal 42 of columned main body 41 and main body 41 two ends.Supporting mechanism 5 comprises top base 51, guide post 52, stage clip 53, pressing plate 54, bottom base 55 and connector 56.Top base 51 is provided with screwed hole 511 and through hole 512.Pressing plate 54 upper surfaces are provided with projection 541, and the lower surface is provided with first cambered surface 542 with axle journal 42 coupling of roller 4, and its both sides are provided with second cambered surface 543 with guide post 52 couplings.Bottom base 55 be provided with the installing hole 551 corresponding with the screwed hole 511 of top base 51 and thereon the middle part on surface also be provided with the 3rd cambered surface 552 with axle journal 42 couplings.
Structure after the assembling as shown in Figure 4 and Figure 5, insert in the through hole 512 of top base 51 upper end of guide post 52, its lower end abutment is on the upper surface of bottom base 55.The main body 41 of roller 4 places the through hole 22 of base plate 2, and its axle journal 42 is placed between first cambered surface 542 of the 3rd cambered surface 552 of bottom base 55 and pressing plate 54.Pressing plate 54 is socketed on the guide post 52 movably by second cambered surface 543 of its both sides.One end of stage clip 53 is socketed on the projection 541 of pressing plate 54, and the other end is resisted against on the top base 51.Connector 56 passes the through hole 23 on the base plate 2, the installing hole 551 of bottom base 55 is threaded with the screwed hole 511 of top base 51.
When the needs electric circular saw cuts, electric circular saw is placed on surface of the work, because total elastic force of stage clip 53 is substantially equal to the gravity of fuselage 1 and base plate 2 in the guider 3, the operator uses very little pressure to make in the process that advances and moves on roller 4 compression press springs 53, thereby reduced the height of base plate bottom surface 21, made it to be difficult for rollover with surface of the work.
With reference to Fig. 6 and shown in Figure 7, in the present invention's second preferred embodiment, guider 30 comprises roller 40 and two supporting mechanisms 50 that connect roller 40 and base plate 2.Supporting mechanism 50 comprises pedestal 501, torsion spring 502, crank 503 and connector 504, and wherein pedestal 501 is provided with vertical screwed hole 5011 and horizontal hole 5012.Roller 40 is provided with centre bore 401 (see figure 8)s.
Structure after the assembling such as Fig. 8 and shown in Figure 9, roller 40 rotatably is socketed in the middle part of crank 503 by its centre bore 401, and is housed in the through hole 22 of base plate 2.Torsion spring 502 is socketed in the end of crank 503 and is housed in therewith in the hole 5012 of pedestal 501, and wherein an end of torsion spring 502 is connected with crank 503, and the other end is connected with pedestal 501.The through hole 23 that connector 504 passes on the base plate 2 is threaded with hole 5011 on the pedestal 501.
When the needs electric circular saw cuts, electric circular saw is placed on surface of the work, because total elastic force of torsion spring 502 is substantially equal to the gravity of fuselage 1 and base plate 2 in the guider 30, the elastic force that the operator uses very little pressure can make crank 503 overcome torsion spring 502 in the process that advances rotates around rotating shaft A3, reduced the height of base plate bottom surface 21 thereby drive to move on the roller 40, made it to be difficult for rollover with surface of the work.
Referring to Figure 10,11 and Figure 12, the present invention's the 3rd preferred embodiment, guiding mechanism 300 comprises roller 400 and flexible member 500.Base plate 200 has been wholely set support 2001.Roller 400 comprises the extended axle journal 4002 of columned main body 4001 and main body 4001 two ends.One end of flexible member 500 hangs on the support 2001 that is located at base plate 200, and the other end is set on the hook-shaped axle journal 4002 that directly is socketed in roller 400.When electric circular saw in use, move on roller 400 compression elastic elements 500, thereby reduced the height of base plate bottom surface and surface of the work, make it to be difficult for rollover.
In two preferred embodiments of the present invention, the outer surface of roller 4,40,400 uses flexible material, as rubber, plastics etc. to obtain bigger side-friction.The direction of central shaft A1, the A2 of roller 4,40,400, A4 and saw blade cutting is vertical all the time, makes the easier cutting straight line of saw blade.
Any based on inventive concept of the present invention; thereby the height that uses flexible member reduction guider to stretch out base plate keeps the scheme of the balance of electric circular saw base plate all to belong to the scope of protection of the invention, and roller also can be separately positioned on the balance that the saw blade both sides keep the electric circular saw base plate certainly.
