Wherein, saw blade is stirred control that device 60 can be subjected to the saw blade feed arrangement to act on the sawtooth of saw blade 100, this saw blade 100 is rotated, thereby the sawtooth abrasion site that is fed to one by one is beneficial to grind.
Wherein, this saw blade stabilising arrangement 70 is fixed on the support 10, it has a pair of expansible and closed supporter 73, the circumferential location of these saw blade 100 contiguous these emery wheels 45 is arranged in this supporter 73, the positive and negative of this supporter 73 contact saw blades 100 to be supporting this saw blade 100, thereby avoids problems such as this saw blade 100 shakes, shakes, distortion.
Referring to Fig. 2, shown an embodiment of this saw blade stabilising arrangement, this saw blade stabilising arrangement 70 comprises location-plate 71, linkage 72, supporter 73 and linkage driven unit 22.
Wherein, this location-plate 71 is L shaped slicer board, and an end on the limit that this is L shaped is fixed on the support 10, and another limit has upper surface and lower surface.
Wherein, linkage 72 has a fixed connecting piece 721, and this fixed connecting piece 721 is fixed in arbitrary surface on another limit of location-plate 71 by screw;
Wherein, supporter 73 is connected in this linkage 72, the circumferential section of this saw blade 100 of supporter 73 clampings.
Wherein, linkage driven unit 22 comprises actuator 23 and operator 24, this actuator 23 has first end 231 and second end 232, these first end, 231 rotatable linkages 72 that are connected in, this operator 24 is rotatable to be connected in this location-plate 71 and can back and forth to rotate, and second end 232 of this actuator 23 is connected on this operator 24.
Thus, this operator 24 back and forth rotates and moves to drive these actuator 23 reciprocal linear, and this linkage 72 of push-and-pull makes this linkage 72 produce corresponding link motion, and makes this supporter 73 unlatchings and closed thus.
Wherein, this clamping bar 731 probably is＜shape, the middle part 81 of two clamping bars 731 rotatably is bolted in the two ends of the fixed connecting rod 721 of linkage 72, each clamping bar 731 has first end 733 and second end 734, the circumferential surface of the contact 735 of 735, two clamping bars of one contact in order to contact saw blade 100 is set on this second end 734.
Wherein, this linkage 72 also comprises one first motion bar 722, one second motion bar 723 and one the 3rd motion bar 724,231 rotatable connections of first end of the middle part of this first motion bar 722 and above-mentioned actuator 23, one end of this second motion bar 723 is movably connected on an end of this first motion bar 722, the other end of this second motion bar 723 is movably connected on first end 733 of a clamping bar 731, one end of the 3rd motion bar 724 is movably connected on the other end of this first motion bar 722, and the other end of the 3rd motion bar 724 is movably connected on first end 733 of another clamping bar 731.
Wherein, this operator 24 comprises a swiveling wheel 25 and spanner 26, swiveling wheel 25 rotatable being fixed on the location-plate 71, and spanner 26 is arranged on the circumference of swiveling wheel 25, and on the rotatable wheel rim that is connected in swiveling wheel 25 of actuator 23 volumes second end 232.
Wherein, this actuator 23 is an expansion link, is with a compression spring 27 on this actuator 23, and this operating parts 26 can be positioned at the primary importance shown in Figure 3 or the second place shown in Figure 4 by pulling.
When spanner 26 is pulled to the second place from primary importance, this actuator 23 of driving that rotatablely moves of this swiveling wheel 25 moves forward, this actuator 23 applies a flexible thrust to linkage 72 by compression spring 27 thus, thereby driving first motion bar 722 moves forward, thus, by second motion bar 723 of linkage 72 and first end 733 of the 3rd motion bar 724 pushings two clamping bars 731, two clamping bars 731 are rotated relative to middle part 81, make second section 734 of two clamping bars 731 to relatively move, thereby by the circumferential surface of contact 735 contact saw blades 100, make this saw blade 100 supported respectively.
When spanner 26 from the second place when primary importance moves, these swiveling wheel 25 reverse rotations, first motion bar 722 is moved backward, linkage 72 produces pulling force, make first end of this second motion bar 723 and the 3rd motion bar 724 these clamping bars 731 of pulling, make moving that 734 at second end becomes to leave, make contact 735 break away from the circumferential surface of saw blades 100.
