One shell 70, these shell 70 covers close in this main body 20, are located between this master, the shell 20,70 for this saw blade 60 and protecting cover 61, and can be with respect to the outside against this shell 70 for this guide wheel 66; By above-mentioned structure, turn over the eye-protection cover of finishing the utility model cutting machine and to lift structure.
Following in untapped situation, as shown in Figures 2 and 3, if do not push this button 26, and this master, when shell 20,70 is subjected to pressing down strength, be subjected to the guiding of these guide rod 51 climbing powers owing to the track 64 of this protecting cover 61, form this protecting cover 61 and be formed with turning over of moving and lift strength to piece 65, should support the stop section 42 that piece 65 can be resisted against this guide rod 51 this moment, should move on piece 65 to place restrictions on, and then this protecting cover 61 of block turns over and raises, prevent that saw blade 60 from exposing, increase the security of unused state.
When general normal use, as Fig. 2, Fig. 4 and shown in Figure 5, it is to open this drive unit 30, make this this mandrel 23 of drive unit 30 interlocks and saw blade 60 rotations, push this button 26, this baffle plate 40 of interlock is the center rotation with this pivot 41, compresses second torsionspring 63, and this stop section 42 is rotated into towards these mandrel 23 directions, and what break away from this track 64 supports piece 65 tops;
Pushing this handle 31 simultaneously moves down, making this saw blade case 22 is that the center rotates down together with this fixed idler whell 55 with the position that is pivoted, articulated section 21, compress this first torsionspring 63, and the section of being pivoted 52 of this guide rod 51 is hubbed at this sliding seat 11, move along this steady pin 54 in arc hole 25 for this articulated section 21, and change the distance of this steady pin 54 and this fixed idler whell 55, make the setting guide face 57 of this guidance part 53, and can move along this fixed idler whell 55, drive this guidance part 53 together with moving on this action roller 56, and then the track 64 of this protecting cover 61 of interlock moves along this action roller 56, compress the 3rd torsionspring 63, this protecting cover 61 turned over raise, and prevent that effectively this saw blade 60 is exposed towards the cutting end direction.
When this saw blade 60 moves to lowermost end, as shown in Figure 6, this moment, track 64 ends of this protecting cover 61 moved to this action roller 56, and then for these track 64 these action rollers 56 of disengaging, and the guide wheel 66 of this protecting cover 61 can slide on this board 10 surfaces, effectively cover protects this saw blade 60, prevents that saw blade 60 from exposing.
When saw blade 60 when cutting off workpiece 80, as Fig. 2 and shown in Figure 7, this moment, this guide rod 51 surpassed this guide rod 51 towards this terminal position to piece 65, the guide wheel 66 of this protecting cover 61 is subjected to the contact of workpiece 80 at this moment, this protecting cover 61 just can be turned over along the surface of this workpiece 80 and raise, and continue compression the 3rd torsionspring 63, reach this protecting cover 61 and can turn over along these workpiece 80 surfaces and raise, reduce the danger that this saw blade 60 directly exposes.
After the cut-out workpiece is finished, as shown in Figures 2 and 3, the restoring force of this first torsionspring 63, can should lead, shell 20,70 returns back to previous status together with drive unit 30 etc., and the restoring force of the 3rd torsionspring 63, this protecting cover 61 can be covered with back this saw blade 60 in the part that exposes this main body 20, and the guide wheel 66 of this protecting cover 61 supports and close in this shell 70 bottom sides, and the restoring force of this second torsionspring 63 can provide this baffle plate 40 to rotate to this stop section 42 to be positioned at this on piece 65.
Adopt above-mentioned structure, the eye-protection cover of the utility model cutting machine turns over and lifts structure and have following advantage:
1. it is good that cover closes effect
The utility model utilizes the design of this guiding device and the 3rd torsionspring, and this eye-protection cover energy is provided Turn over along the apparent height of this workpiece and to raise, make this eye-protection cover and surface of the work form cover and close state, prevent saw Sheet exposes and the splashing of smear metal.
2. prevent misoperation
The utility model utilizes this baffle plate can be at cutting machine under unused state, for the gear of this guide rod End section's block in the piece that supports of this track, prevent that turning over of this protecting cover from raising, reach this protecting cover and do not make at cutting machine Under state, this protecting cover can effectively cover and close in this saw blade periphery, prevents that the exposed danger of saw blade from taking place.
3. the scope of application is big
Protecting cover of the present utility model can turn over along the profile height of workpiece and lift, and this protecting cover can turn over fully and lifts to this In saw blade case and the shell, increase the height of sawing workpieces, promote the scope of application of sawing workpieces.
