The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Shown in Fig. 1-4, electric miter saw of the present utility model comprises base 1, be installed on be used on the base 1 positioning workpieces by grid 16, rotatably be connected in workbench 2 on the base 1, be installed on the swing arm 4 of workbench 2 afterbodys rotatably.Swing arm 4 on workbench 2, makes swing arm 4 and workbench 2 form with the relative rotation a cutting angle of setting by swing arm locking button 3 fixing and lockings.
Ground floor slide rail locking member 7, second layer slide rail locking member 9 are set respectively in slide block 6, the rotating shaft 10, are locked each movable slider is relative with slide rail respectively.
When on the slide block 6 two second layer slide rails 11 being set, can slide or be fixedly connected with between the second layer slide rail 11 relative slide blocks 6.Better scheme is, the rear end of two second layer slide rails 11 is fixedly connected on the slide block 6, and the front end of two second layer slide rails 11 extends forward workbench 2 tops.
Saw comprises motor 12, saw blade 15 and pivotally connected motor frame 13 in rotating shaft 10, and saw blade 15 is arranged on the motor frame 13, and can be rotated by motor 12 drivings, realizes the cutting to workpiece.
Ground floor slide rail 5, second layer slide rail 11 are arranged at respectively two sides of saw blade 15, do not interfere the saw blade cutting movement.The front end of two ground floor slide rails 5, two second layer slide rails 11 is fixedly connected with by ground floor slide rail Connection Block 8, second layer slide rail Connection Block 14 respectively, be beneficial to and keep the stable of slide rail, the depth of parallelism of two one slide rails in improving every layer, the convenient manufacturing installed, and makes slide rail can arrange longlyer, has larger cutting stroke, shown in Fig. 5,6, when equal cutting stroke, the length of every layer of slide rail can be shorter, reduces manufacture difficulty; And ground floor slide rail Connection Block 8, second layer slide rail Connection Block 14 also can carry out respectively spacing to the slip of slide block 6, rotating shaft 10, in order to avoid the slide rail that slide block 6, rotating shaft 10 breaks away from its place when sliding.If in the time of can sliding between the second layer slide rail 11 relative slide blocks 6, then in like manner also need to arrange Connection Block or locating part in the rear end of second layer slide rail 11.
As shown in Figure 2, two ground floor slide rails 5 are positioned at the right side of saw blade 15, two second layer slide rails 11 are positioned at the left side of saw blade 15, and the space between ground floor slide rail 5 and the second layer slide rail 11 can hold saw blade 15, rotating shaft 10, motor frame 13 and shuttle back and forth therein to slide and carry out cutting movement.Because the saw of slide rail and motion does not move interference, therefore, as shown in Figure 5, saw can move along slide rail and bounce back to it near the rear end of swing arm 4, and slide rail can not stretch out to the swing arm rear, has greatly shortened the working space of mitre saw, has reduced packaging volume.
Better scheme is, as shown in Figure 2, the angled a in plane at relative saw blade 15 places, plane, center line place of two ground floor slide rails 5, the angled b in plane at relative saw blade 15 places, plane, center line place of two second layer slide rails 11,11 grasping parts that form V-type of ground floor slide rail 5 and second layer slide rail, the larger end of V-type opening up, motor frame 13 in the time of can holding the saw slip, rotating shaft 10 is passed, the less other end of V-type opening is towards the workbench 2 of below, saw blade 15 in the time of can holding the saw slip shuttles back and forth, motor 12 is positioned on each slide rail, does not move interference with slide rail.And, after ground floor slide rail 5, second layer slide rail 11 tilt, make towards the V-type opening of workbench 2 less, make swing arm 4 drive ground floor slide rail 5, second layer slide rail 11 when axial rotation, with by grid 16 do not move interference, effectively avoid on the base 1 by grid 16, fully rationally utilize the space, make the mitre saw more compact structure.Preferably, the asymmetric inclination in plane at ground floor slide rail 5, second layer slide rail 11 relative saw blades 15 places, second layer slide rail 11 is positioned at the side top of ground floor slide rail 5, be that second layer slide rail 11 is little with the angle of saw blade 15 than ground floor slide rail 5 with the angle of saw blade 15, or second layer slide rail 11 relative ground floor slide rails 5 are further from workbench 2, so that the center of gravity relative equilibrium of each structure of saw blade 15 both sides provides larger cutting angular field of view, keep the stable of mitre saw, avoid rollover.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
