Abstract

The invention relates to a sawing machine. The machine comprises a frame (3), a motor (5) and a saw blade (2), wherein the saw blade (2) is rotatably arranged on the upper part of the frame (3); and an output shaft of the motor is linked with the saw blade through a transmission device. The machine is characterized in that: the top surface of the frame (3) is provided with a push plate (4) on which an object to be sawn can be put and which can slide with the object to be sawn back and forth; a strip cavity (41) is formed in the push plate (4); and the saw blade is positioned in the cavity (41) of the push plate (4). Compared with the prior art, the invention has the advantages that: 1, the object to be sawn is put on the push plate when sawn, so the object to be sawn can easily move forwards with the push plate, and a sawn position is easy to control; and 2, the machine is more conveniently and simply operated as long as hands contact the push plate to push the push plate forwards during sawing, and force is applied less and more uniformly and the machine is more safely operated because the push plate rolls forwards through a pulley.

Description

A kind of sawing machine

Technical field

The present invention relates to a kind of power tool technical field, especially refer to a kind of sawing machine.

Background technology

Existing a kind of application number discloses a kind of structure for the Chinese invention patent that the CN201010511176.5 name is called " having the initiatively bench saw of lockable mechanism ", and its structure comprises: a workpiece support face; One rocker arm assembly that can between the first rocking arm position and the second rocking arm position, move along the swing path, in the first rocking arm position; the part of the shaped device that rocker arm assembly supported extends to workpiece support face top; in the second rocking arm position, this part of shaped device does not extend to the top of workpiece support face; One latch pin, it can pivot between the primary importance and the second place, and in primary importance, latch pin engages with rocker arm assembly, and in the second place, latch pin does not engage with rocker arm assembly; One actuator, its setting is used for latch pin is pivoted to the second place from primary importance, and forces rocker arm assembly to leave the first rocking arm position to move towards the second rocking arm position; And a control system, it is arranged to start actuator in response to the situation of sensing.The shortcoming of this bench saw is, needing to be cut thing during sawing pushes away forward, and table top is motionless, can bring a lot of uneasy umbra elements to sawing like this, because sawing is need push hard by the saw thing, not only firmly wants big, and accidentally will injure hand, also have this bench saw because of firmly inhomogeneous, sawing face also is difficult to control; Have, this is sawed when sawing again, and dust is very big, makes troubles to sawing, so its structure awaits to improve.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of project organization a kind of sawing machine simple, ingenious, easy and safe to operate at above-mentioned prior art present situation.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this sawing machine, include frame, motor and saw blade, described saw blade can be arranged at the top of frame rotationally, the output shaft of described motor links by transmission device and saw blade, it is characterized in that: the end face of described frame is provided with can be put thereon by the saw thing and the push pedal of front and back slip together, have the bar shaped cavity in the described push pedal, described saw blade is arranged in the cavity of push pedal.

As improvement, described push pedal can before and after the concrete structure that slides can be preferably, be provided with slide rail at the end face of frame, on the bottom surface of push pedal, pulley is set, described pulley can place on the slide rail scroll forward and backward.

Improve, described slide rail can be preferably two again, and these two slide rails are arranged on the frame with the structure that is parallel to each other.

Improve, the front end of described slide rail can be respectively arranged with the preceding catch that anti-limited slip wheel skids off slide rail again, also is provided with the back catch that anti-limited slip wheel skids off slide rail in the rear end of slide rail.

Improve again, also can be provided with the pushing hands portion of conveniently shaking hands on the rear upper surface of described push pedal.

Improve, the rear portion of described push pedal and the end that is positioned at cavity can be provided with the backplate of avoiding hand to run into saw blade again, bring damage to prevent hand from touching on the saw blade.

Improve, the rear portion of described push pedal and the end that is positioned at cavity are provided with the baffle plate of placing by the saw thing, can will be moved forward by the saw thing more easily again.

Improve, the top of described saw blade also can be provided with dust shield again, and the air suction opening in this dust shield is connected with dust catcher by sweep-up pipe.

Improve, described dust catcher and motor are individually fixed on the base of frame bottom again.Make sawing machine integral body more neat, take up space forr a short time, simultaneously appearance is also more attractive in appearance.

Improve, described dust shield is fixed on the frame by two vertical support bars, thereby dust shield is firmly fixed on the frame again.

Compared with prior art, the present invention adopts frame to be provided with and can be put thereon the also push pedal of front and back slip together by the saw thing at end face, has the bar shaped cavity in the described push pedal, and described saw blade is arranged in the cavity of push pedal.The advantage of this design is, the first, because of being placed in the push pedal when the sawing, can be moved forward like a cork along with push pedal by the saw thing like this by the saw thing, and be easy to control the sawing position; The second, more convenient operation during sawing, simple, hand when sawing is as long as the contact push pedal pushes away forward, because of push pedal is rolled forward by pulley, so firmly also still less, more even, and operation is electric safer; The 3rd, the present invention is provided with dust shield above saw blade, and the air suction opening in this dust shield is connected with dust catcher by sweep-up pipe.Like this during sawing, the dust that sawing is got off directly is inhaled in the dust catcher, can in air, not fly upward, not only reduce the soakage of operating personnel to dust, and the maintenance health of operators, and sight line is also clearer, and the sawing position is more accurate, thereby further improves the convenience and the security of operation.
