Description
Technical field
Prevent collapsing carpenter's circular saw workbench and its application method the present invention relates to one kind.
Background technology
Building engineering construction on-site cutting flitch, template must use carpenter's circular saw.Due to environmental requirement, some flitches
Formed using the old wood sawing such as old room beam, purlin, these old timber have steel nail to hide wherein often, and many flitches and template are also
Reusability is needed, the flitch and template of these Reusabilities also more is concealed with steel nail, nailing etc..Once carpenter's circular saw can not
When the heart cuts steel nail, nailing, often cause sawtooth to break, and after broken teeth, steel nail, nailing are often thrown away at a high speed, trigger
Casualty accident.Therefore, people set up semi-circular guard by the saw blade of carpenter's circular saw, but existing semi-circular guard is all
Fixation is non-adjustable, is not influence sawing timber, typically all by semi-circular guard fixed range circular saw table surface farther out
On position, but so gap is increased, and broken teeth, steel nail, nailing are still easily thrown out of.
The content of the invention
The technical problem to be solved in the present invention is how to solve that carpenter's circular saw shield adjustment is inconvenient, unsafe shortcoming,
One kind is provided to prevent collapsing carpenter's circular saw workbench and its application method.
In order to solve the above technical problems, this anti-carpenter's circular saw workbench that collapses includes workbench, carpenter's circular saw and semicircle
Shape protective cover, carpenter's circular saw includes being provided with T-shaped groove, T-shaped groove on circular saw blade and motor, the workbench
It is made up of a rectangular slot and strip groove, rectangular slot in the middle part of strip groove with connecting, and the motor is installed
In rectangular slot, the circular saw blade is fixed on the output shaft of motor, and the circular saw blade stretches out from bottom to top
Outside strip groove, half-round shield is hung in above the circular saw blade, it is characterised in that：It also includes flexible davit and pulley
Group device, the flexible davit is made up of outer square tube and interior square tube, and its Chinese and foreign tube top portion is fixed, and the interior square tube is set outside
In square tube, outer square tube front and rear sides are respectively equipped with vertical chute, the outer square tube and are fixed with traveller, and the traveller can slided vertically
Slide up and down, moved up and down so as to square tube in limitation, guiding in outer square tube, the half-round shield is fixed on interior side in groove
Pipe lower end, the assembly pulley device includes a movable pulley, at least one fixed pulley, rope and a spud pile, the dynamic cunning
Wheel is directly or indirectly fixed in half-round shield, and the fixed pulley is fixed on above half-round shield, the spud pile
Multipair equally distributed hook is provided with, what described rope one end tied up to outer square tube lower end is on hole, the other end is across movable pulley
And fixed pulley, it is and is wrapped on a link, the link is to be provided with one in the middle of openings ring, the openings ring a line to lead to
Hole, with this at parallel one on be provided with breach, the rope is just tied up in the through hole, and is partially around the side of through hole both sides
On, each pair hook is made up of left hook and right hook, and minimum clearance therebetween is more than rope overall diameter, and left hook and right hook are by solid
Determine substrate and downward arcuated hook plate is constituted, fixed substrate is fixed on spud pile by rivet, and the openings ring can select one
It is stuck on different hooks.
In use, according to the lumber thickness for treating sawing, adjusting the position of link, treat that the timber of sawing is thick, link is moved down, half
Circular protective cover rises；Treat that the timber of sawing is thick, link is moved up, reduced under gravity, half-round shield lower edge is begun
Eventually with treating that the timber upper surface of sawing keeps 0.5~1 centimetre of gap, hung on different hooks, carried out by link selection
Half-round shield height coarse adjustment；The number of turn of snap ring is wrapped in by adjusting rope, half-round shield height fine-adjustment is carried out.
It is so designed that, neither influence processing timber, is not susceptible to collapse saw casualty accident again.Process the timber of different-thickness
When, link only need to be hung over to the hook of different height, it is very convenient.
As optimization, the fixed pulley at least includes two, and at least one fixed pulley is located above spud pile, and one fixed
Pulley is located above half-round shield, a scale is further fixed between spud pile and fixed pulley, the scale is parallel to fixed
A pointer is additionally provided with rope between pulley and spud pile, the rope, when half-round shield lower edge and circular saw blade
When outer most edge is tangent, top dead centre of the pointer just to the scale stage casing, when half-round shield lower edge is on workbench
During 1 millimeter of surface, lower dead center of the pointer just to the scale stage casing, the top dead centre of scale marks 2 millimeters, then from upper
Under mark the numerical value being gradually increased successively, the lower dead center mark numerical value of scale can sawing for this anti-carpenter's circular saw workbench that collapses
The maximum gauge of timber.It is so designed that,.
As optimization, the strip groove is connected with a horizontal groove stage casing, and the sawtooth of the circular saw blade is from upper
Under, by horizontal groove, the steel nail being likely to occur in sawing timber is treated, can pass through from horizontal groove, fall on below workbench.
It is foregoing to prevent collapsing carpenter's circular saw workbench application method, comprise the steps：
1) openings ring is selected one and is stuck in different extensions by according to the numerical value in the thickness value and scale for the treatment of sawing timber
On hook, make to differ minimum between thickness value of the numerical value on pointer indicator scale with treating sawing timber, to half-round shield
Highly carry out coarse adjustment；
2) is according to the numerical value in the thickness value and scale for the treatment of sawing timber, by adjusting rope on openings ring
Wind the number of turn, make it is equal between thickness value of the numerical value on pointer indicator scale with treating sawing timber, to half-round shield
Highly carry out accurate adjustment；
3) starts motor, will treat that sawing timber pushes circular saw blade to along workbench, is processed.
The present invention prevents that collapsing carpenter's circular saw workbench has simple in construction, the advantage of safe ready, is widely used in building
In the timber process in building site.
