Abstract
The utility model discloses a mechanism having a saw blade cover of a cutting machine always keep horizontal, wherein the mechanism comprises a saw blade cover, a connecting plate, a power base plate and a frame. The saw blade cover is hinged with the connecting plate via the point A and with the power base plate via the point B. The frame is hinged with the power base plate via the point C and with the connecting plate via the point D. The distance between the hinge points A and B on the saw blade cover is equal to that between the hinge points C and D on the frame. The distance between the hinge points A and D on the connecting plate is identical to that between the hinge points B and C on the power base plate. The connection line between the hinge points C and D on the frame is in the vertical direction. According to the parallel four-bar mechanism theory, the swing of the portion BC around the point C drives the portion AD to swing around the point D and the portion AB is in the vertical direction because the portion CD is in vertical direction. That is, during the swing of the power base plate and the connecting plate, the saw blade cover always maintains in the horizontal state, which not only does not decrease the maximum cutting depth, but also effectively protects the operator.
Description
Technical field
The utility model technology relates to the mechanism that a kind of cutting machine saw blade cover remains level, be specially adapted to diamond saw blade supporting, the makita 4100NH that carries out the cutting of ceramic tile, marble tile.
Background technology
At present in building, finishing field, often use cutting machine to carry out the cutting of stone materials such as ceramic tile, marble, existing cutting machine saw blade cover is fixed on the power base plate, as shown in Figure 4, when raising or forcing down the handle of power base plate, power base plate and saw blade cover are together along with the pin joint of power base plate and frame rotates, saw blade cover lower limb and workbench are angled, maximum depth of cut is reduced, and influence operator's sight line or cause saw blade to face toward the operator and expose too much, exist potential safety hazard.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art; provide a kind of cutting machine saw blade cover to remain the mechanism of level, realized cutting machine when the power base plate rotates, the saw blade cover remains level; not reducing depth of cut simultaneously, protect the operator again effectively.
The technical solution of the utility model is: a kind of cutting machine saw blade cover remains the mechanism of level, is made up of saw blade cover, connecting plate, power base plate and frame; Saw blade cover and connecting plate are point articulated by A, and be point articulated by B with the power base plate; Frame and power base plate are point articulated by C, and be point articulated by D with connecting plate.
Saw blade cover upper link point A equates to the distance C D of D with frame upper link point C to the distance A B of B; Connecting plate upper link point A is to the distance A D of D and power base plate upper link point B equating apart from BC to C; The line CD of frame upper link point C and pin joint D is at vertical direction.
The beneficial effects of the utility model are: overcome deficiency of the prior art; provide a kind of cutting machine saw blade cover to remain the mechanism of level; when raising or forcing down the handle of power base plate; the power base plate rotates around the pin joint of power base plate and frame; the saw blade cover rotates and remains level around the pin joint of saw blade cover and power base plate; not reducing depth of cut simultaneously, protect the operator again effectively.
Description of drawings
Accompanying drawing 1 is the structural scheme of mechanism that a kind of cutting machine saw blade cover remains level;
Accompanying drawing 2 is structural scheme of mechanism that a kind of cutting machine saw blade cover remains level;
Accompanying drawing 3 is that the utility model is worked as power base plate schematic diagram when turning an angle;
Accompanying drawing 4 is existing cutting machine schematic diagrames when the power base plate turns an angle.
The specific embodiment
Figure of description is an enforcement preferred version of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2: a kind of cutting machine saw blade cover remains the mechanism of level, is made up of saw blade cover 1, connecting plate 2, power base plate 3 and frame 4; Saw blade cover 1 is point articulated by A with connecting plate 2, and is point articulated by B with power base plate 3; Frame 4 is point articulated by C with power base plate 3, and is point articulated by D with connecting plate 2.
According to the parallelogram lindage theory, when BC swings around a C, drive AD around a D swing, because CD is a vertical direction, then AB also is a vertical direction, and just power base plate 3 and connecting plate 2 are in swing process, and saw blade cover 1 remains level, as shown in Figure 3.
