Abstract
The utility model discloses a limit device of a compound saw. The limit device comprises a lifting shaft, a safety baffle and a baffle ejector rod. The lifting shaft is sleeved with a spring, one end of the lifting shaft is positioned on the bottom surface of a table of a table saw, and the other end of the lifting shaft is contacted with the upper end surface of the safety baffle; the safety baffle is rotatably positioned on a machine body; and the baffle ejector rod is positioned on a table of a miter saw and corresponds to the safety baffle. By the cooperation of the safety baffle and the baffle ejector rod, the compound saw is limited and fixed, so that the compound saw is effectively limited when being changed to different working conditions. The limit device of the compound saw has the advantages that the structure is simple, the operation is convenient, the working is reliable, etc.
Description
Technical field
The utility model relates to the accessory on a kind of compound saw, is specifically related to a kind of stopping means that can effectively play the compound saw of position-limiting action, simple in structure, reliable operation when compound saw switches to the different operating state.
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 must satisfy following the requirement: 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 complexity, parts are many, complex operation step, locking effect are unreliable, diagonal cutting saw misoperation when bench saw work often occurring, the perhaps phenomenon of bench saw misoperation during diagonal cutting saw work.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model 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 utility model comprises lifting shaft, safety screen and baffle plate push rod, is with spring on the described 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; Described safety screen is rotatable to be installed on the body, and described baffle plate push rod is installed in position corresponding with safety screen on the diagonal cutting saw workbench.
Described safety screen is installed on the body by rotating shaft and torsion spring, and safety screen can rotate along rotating shaft.
The upper surface of described safety screen is the plane.
As another kind of scheme, on the described diagonal cutting saw workbench protective cover is installed, described 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 utility model, compound saw is carried out spacing and fixing by 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 schematic diagram of each assembly of the utility model;
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 utility model is done further explanation.
As depicted in figs. 1 and 2, the stopping means of compound saw of the present utility model 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 by rotating shaft 8 and torsion spring 7, 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 utility model 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, makes 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 mutually 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 mutually in the lower surface of the inclined-plane of baffle plate push rod 3 and safety screen 2, safety screen 2 is subjected to 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, bench saw workbench 5 is depressed into when minimum, and saw blade exposes the upper table surface of bench saw workbench 5, and locking handles knob 10, the bench saw table lock is fastened the safety in the time of to guarantee work.
The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
