Abstract
The invention discloses a limiting device of a composite saw, which comprises a lifting shaft, a safety baffle plate and a baffle plate ejecting rod, wherein a spring is sleeved on the lifting shaft, one end of the lifting shaft is installed on the bottom surface of a bench saw workbench, and the other end of the lifting shaft contacts the upper end surface of the safety baffle plate; and the safety baffle plate is rotatably installed on a machine body, and the baffle plate ejecting rod is installed on an oblique saw workbench at a position corresponding to the safety baffle plate. The limiting device of the composite saw is used for limiting and fixing the composite saw through the mutual matching of the safety baffle plate and the baffle plate ejecting rod, so that the composite saw can be effectively positioned when switched to different working states, and the limiting device has the advantages of simple structure, convenient operation, reliable working and the like.
Description
Technical field
The present invention relates to the accessory on a kind of compound saw, be specifically related to a kind of stopping means that when compound saw switches to the different operating state, can effectively play the compound saw of position-limiting action, simple in structure, reliable operation.
Background technology
At present, compound saw is widely used in fields such as machine-building as a kind of electric tool commonly used.Compound saw can switch to diagonal cutting saw and two kinds of duties of bench saw respectively.Compound saw in use requires below must satisfying: when switching to the bench saw duty, and during the operation bench saw, the diagonal cutting saw akinesia; When switching to the diagonal cutting saw duty, during the operation diagonal cutting saw, the bench saw akinesia.This just need install interlock on compound saw.But existing locking device structure is complicated, parts are many, complex operation step, locking effect are unreliable, diagonal cutting saw misoperation when bench saw work often occurring, the phenomenon of bench saw misoperation when perhaps diagonal cutting saw is worked.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of stopping means of simple in structure, easy to operate, the reliable compound saw in location.
Technical scheme: for solving the problems of the technologies described above; The stopping means of compound saw of the present invention comprises lifting shaft, safety screen and baffle plate push rod, is with spring on the said lifting shaft; Lifting shaft one end is installed in the bottom surface of bench saw workbench, and the lifting shaft other end contacts with the upper surface of safety screen; Said safety screen is rotatable to be installed on the body, and said baffle plate push rod is installed in position corresponding with safety screen on the diagonal cutting saw workbench.
Said safety screen is installed on the body through rotating shaft and torsion spring, and safety screen can rotate along rotating shaft.
The upper surface of said safety screen is the plane.
As another kind of scheme, on the said diagonal cutting saw workbench protective cover is installed, said baffle plate push rod is installed in position corresponding with safety screen on the protective cover.
Beneficial effect: the stopping means of compound saw of the present invention; Compound saw is carried out spacing and fixing through cooperatively interacting of safety screen and baffle plate push rod; Can access effective location when making compound saw switch to the different operating state, have advantages such as simple in structure, easy to operate, reliable operation.
Description of drawings
Fig. 1 be compound saw under the diagonal cutting saw duty, the mutual alignment sketch map of each assembly of the present invention;
Fig. 2 is the structural representation of compound saw under the diagonal cutting saw duty.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As depicted in figs. 1 and 2; The stopping means of compound saw of the present invention comprises lifting shaft 1, safety screen 2 and baffle plate push rod 3, is with spring 4 on the lifting shaft 1; Lifting shaft 1 one ends are installed in the bottom surface of bench saw workbench 5, and lifting shaft 1 other end contacts with the upper surface of safety screen 2; Safety screen 2 rotatable being installed on the body, baffle plate push rod 3 are installed on the diagonal cutting saw workbench 6 position corresponding with safety screen 2.
In practice, safety screen 2 is installed on the body through rotating shaft 7 and torsion spring 8, and safety screen 2 can rotate along rotating shaft 8.The upper surface of safety screen 2 is the plane.
As another kind of scheme, for the saw blade that prevents to expose damages personnel, protective cover 9 is installed on diagonal cutting saw workbench 6, baffle plate push rod 3 is installed on the protective cover 9 position corresponding with safety screen 2.
The stopping means of compound saw of the present invention requires diagonal cutting saw when work in use, and bench saw can not be worked; During bench saw work, diagonal cutting saw can not be worked.As shown in Figure 1, unclamp locking and handle knob 10, bench saw workbench 5 is lifted to peak under the elastic force effect of spring 4, make saw blade can not expose the upper table surface of bench saw workbench 5, latch 11 is extracted only to be stuck in the body get final product.At this moment, conflict each other in the upper surface of the bottom of lifting shaft 1 and safety screen 2, handles knob 10 even unclamp locking, firmly is pressed on the bench saw workbench 5, and bench saw workbench 5 can not descend yet, and saw blade can not expose the upper table surface of bench saw workbench 5, can not cause danger.
As shown in Figure 2, during the press body, saw blade exposes the following table of bench saw workbench 5 instantly, and the personnel that cause easily injure, so protective cover 9 will be installed on diagonal cutting saw workbench 6.At this moment, when pressing down bench saw workbench 5, contradict each other in the plane, top of the bottom of lifting shaft 1 and safety screen 2; Owing on protective cover 9, be provided with baffle plate push rod 3, so conflict each other in the lower surface of the inclined-plane of baffle plate push rod 3 and safety screen 2, safety screen 2 receives the effect of the inclined-plane power of baffle plate push rod 3; With rotating shaft 8 serves as that axle is rotated, and staggers in the upper surface of safety screen 2 and lifting shaft 1 bottom, and lifting shaft 1 just can continue to descend; Bench saw workbench 5 just can continue to press down, and bench saw workbench 5 is depressed into when minimum, and saw blade exposes the upper table surface of bench saw workbench 5; Locking handles knob 10, the bench saw table lock is fastened the safety in the time of can guaranteeing work.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
