In figure, base 1, workbench 2, swing arm are locked button 3, swing arm 4, ground floor slide rail 5, slide block 6, ground floor slide rail locking member 7, ground floor slide rail Connection Block 8, second layer slide rail locking member 9, rotating shaft 10, second layer slide rail 11, motor 12, motor frame 13, second layer slide rail Connection Block 14, saw blade 15, are leaned on grid 16.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As Figure 1-4, electric miter saw of the present invention comprise base 1, be installed on base 1 for positioning workpieces by grid 16, be connected in workbench 2 on base 1 rotatably, be installed on rotatably the swing arm 4 of workbench 2 afterbodys.Swing arm 4 on workbench 2, makes swing arm 4 and workbench 2 form with the relative rotation the cutting angle of a 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, rotating shaft 10, are locked relative with slide rail each movable slider respectively.
While two second layer slide rails 11 being set on slide block 6, between the relative slide block 6 of second layer slide rail 11, can slide or be fixedly connected with.Preferably scheme is, the rear end of two second layer slide rails 11 is fixedly connected on 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 motor frame 13, and can be driven and be rotated by motor 12, 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 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, convenient manufacture installed, and makes slide rail can arrange longlyer, has larger cutting stroke, as shown in Figure 5,6, in the time of 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 slide block 6, rotating shaft 10 depart from its place slide rail while slip.If can slide between the relative slide block 6 of second layer slide rail 11 time, 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 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 and bounce back to its rear end near swing arm 4 along slide rail, and slide rail can not stretch out to swing arm rear, greatly shorten the working space of mitre saw, reduce packaging volume.
Preferably scheme is, as shown in Figure 2, the angled a of plane at the relative saw blade of center line place plane 15 places of two ground floor slide rails 5, the angled b of plane at the relative saw blade of center line place plane 15 places of two second layer slide rails 11, between ground floor slide rail 5 and second layer slide rail 11, form the grasping part of V-type, the larger one end of V-type opening upward, motor frame 13 can hold saw slip time, rotating shaft 10 is passed, the less other end of V-type opening workbench 2 downward, saw blade 15 can hold saw slip time shuttles back and forth, motor 12 is positioned on each slide rail, do 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 in the time of axial rotation, with by grid 16 do not move interference, effectively avoid on base 1 by grid 16, fully rationally utilize space, make mitre saw more compact structure.Preferably, the asymmetric inclination of plane at ground floor slide rail 5, second layer slide rail 11 relative saw blade 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 compared with ground floor slide rail 5 with the angle of saw blade 15, or the relative ground floor slide rail 5 of second layer slide rail 11 is 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 is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
