Electric circular saw
Technical field
The invention belongs to saw cutting device field, particularly relate to a kind of electric circular saw.
Background technology
Electric circular saw is a kind of conventional sawing electric tool, general is all be fastened on output shaft by securing member by saw blade, rotary work is carried out under the drive of motor, electric circular saw mainly comprises circular saw blade, the saw blade of electric circular saw to be arranged on rotationally on casing and to be driven by motor, casing is also provided with guard shield, prevents saw blade from hurting operating personnel.But electric circular saw is when the work of cutting, and often its contact surface can produce a large amount of heats.Very easily scald the people made with a chainsaw, in addition, along with the rising of temperature, saw blade also can become more fragile, even causes the fracture of saw blade, reduces the service life of saw blade.
In order to solve the heating problem of electric saw, in prior art, often through adding a cooling device on electric saw, saw blade is cooled.Number of patent application is the patent of CN201410202863.7, disclose a kind of electric saw with water cooling function, comprise electric saw body, electricity hydraulic giant, water inlet, piston, switch, jet pipe and sprinkler head, it is characterized in that, in electric saw body one side, the position of saw blade is provided with electric hydraulic giant, the upper end of electric hydraulic giant is provided with water inlet, the piston with sealing process is provided with in water inlet, the front end of electric hydraulic giant is provided with jet pipe, the front end of jet pipe is provided with sprinkler head, the switch of electricity hydraulic giant is connected to the intrinsic motor of electric saw by wire, like this when this body running of electric saw, open the switch on electric hydraulic giant, water in electricity hydraulic giant will be sprayed on the saw blade of electric saw body by jet pipe and sprinkler head uniformly, thus reduce the temperature of saw blade, extend the service life of saw blade.Its shortcoming is: 1. the storage capacity of electric hydraulic giant is limited, and work can face the problem of cooling water deficiency often; 2. what electric hydraulic giant needs were extra sets up a motor, and cost is high, the wasting of resources.
Summary of the invention
The object of this invention is to provide a kind of electric circular saw, to generate heat serious problem to solve electric circular saw.
In order to solve the problems of the technologies described above, the invention provides a kind of electric circular saw, comprise the saw blade be fastened on the output shaft of motor, there is grip part and the guard shield of spatial accommodation, motor is fixed in grip part, guard shield is fixed on grip part, guard shield is positioned at the top of saw blade, also comprise first connecting rod, second connecting rod, piston, piston cylinder and tracheae, one end of first connecting rod is fixed on saw blade, one end of the other end and second connecting rod is hinged, the other end of second connecting rod and piston hinge, piston and piston cylinder match, piston is along piston cylinder axially-movable, piston cylinder is fixed on grip part, the top of piston cylinder is provided with pore, the inlet end of tracheae is communicated with piston cylinder through pore, saw blade bottom is aimed in outlet side.
Principle of the present invention is, one end of first connecting rod is fixed on saw blade, one end of the other end and second connecting rod is hinged, the other end of second connecting rod and piston hinge, so, first connecting rod, second connecting rod and piston composition planar linkage mechanism, saw blade rotates, and drives first connecting rod to rotate, and connecting rod drives piston to move reciprocatingly in piston cylinder, gas after piston compression, is cooled saw blade through tracheae by pore.
Beneficial effect of the present invention is, adopts air-cooled mode to cool saw blade, without the need to considering the problem of cooling fluid, in addition, the present invention, by the rotation of saw blade itself, utilizes planar linkage principle, drives piston compression gas, without the need to separately establishing motor, cost is lower, and has saved the loss of the energy.
Further, tracheae is gooseneck.Gooseneck has excellent resistance to circumnutating property and fatigue durability, as required, is adjusted the position of air pipe outlet by bending tracheae.Carry out air-cooled to high temperature place emphatically on the one hand, strengthen the effect of cooling; On the other hand, after completing cutting operation, the position of air pipe outlet can be adjusted to blow away the chip produced when electric circular saw cuts.
Further, motor is single phase series motor.Single phase series motor belongs to AC and DC dual-purpose motor, and it both can use AC power work, also can use dc source work.
Further, the gas outlet of tracheae is provided with filter screen.Electric circular saw is when cutting article, and can produce a lot of chips, filter screen can well prevent chip from entering into tracheae, avoids chip to block tracheae.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the schematic perspective view of the saw blade part of the embodiment of electric circular saw of the present invention;
Fig. 2 is the front view of the saw blade part of the embodiment of electric circular saw of the present invention.
Detailed description of the invention
Reference numeral during accompanying drawing illustrates is: saw blade 1, first connecting rod 2, piston cylinder 3, gooseneck 4, second connecting rod 5.
The present embodiment provides a kind of electric circular saw, comprise single phase series motor, saw blade 1, there is grip part and the guard shield of spatial accommodation, single phase series motor is fixed in grip part, guard shield is fixed on grip part, and saw blade 1 is fixed on the output shaft of single phase series motor, and guard shield is positioned at the top of saw blade 1.
