Again see Fig. 5, cutting machine is positioned at the first operating position, and now, first axle 40 is positioned at the front side of datum plane A.In this first operating position, saw blade 38, relatively closer to the front side of workbench 32, makes this cutting machine cut wide or have larger advantage at cutting hat material workpiece.As can be cutting-height be the hat material workpiece of 91/2 inch, or higher; Maybe can cut the rectangular workpiece of 2*10 inch, even the workpiece of width more than 10 inches.Certainly because saw blade 38 is earlier, the imaginary intersection point of vertical abutment face 47 and cutting groove 48 can not be passed, so need when cutting rectangular workpiece just can cut padded for workpiece by supporting pad.
Again see Fig. 6, cutting machine is positioned at the second operating position, and now, first axle 40 is positioned at the rear side of datum plane A.In this second operating position, distance W2 between the saw blade axis 31 of saw blade 38 and the vertical abutment face 47 of guardrail 44 is less than cutting machine saw blade axis 31 and the distance W1 vertically between abutment face 47 when primary importance, saw blade 38 is relatively closer to the rear side of workbench 32, so, this cutting machine is being cut wide or is being subject to certain restrictions at the height of cutting hat material workpiece.But in this position, saw blade 38 can pass the imaginary intersection point of vertical abutment face 47 and cutting groove 48 all the time, so be that there is certain advantage at cutting rectangular workpiece.
So, operator just can select to carry out cutting work in the first operating position or the second operating position according to actual needs.Due to cutting work can be carried out at least two predetermined work positions, improve the cutting power of cutting machine; Bracing frame 56 is arranged on connector 57 by this cutting machine rotationally, realizes the movement of cutter unit 36 on the bearing of trend of cutting groove 48, avoids the friction of sliding and producing, thus improve the comfortableness of this cutting machine operation by rotating.
Cutter unit 36 rotates around the second axis 67 relative to connector 54 together with bracing frame 56, when bracing frame 56 arrives predetermined operating position, needs the position of bracing frame 56 to fix relative to connector 54.Thus ensure in cutting process, cutter unit 36 around first axle 40 also relative to connector 54 or workbench 32 relatively fixing, so make cutter unit 36 just can around relative to being the fixing upper and lower pivotable cut workpiece of first axle 40 of workbench 32, thus make simple to operate, also improve cutting accuracy.
As shown in Fig. 3, Fig. 9 and Figure 10, cutting machine comprises retaining mechanism 78 further, and this retaining mechanism 78 has the locking state that bracing frame 56 is fixed at least two predetermined operating positions and allows bracing frame 56 relative to the releasing orientation of connector 54 movement.
This retaining mechanism 78 is applicable to bracing frame 56 pivotable and is connected on connector 54, is also applicable to bracing frame 56 and is slidably connected on connector 54.
See Fig. 3, retaining mechanism 78 comprises operating parts 80, the locking member 82 be connected with operating parts 80 and the counterpart be arranged on connector 54, wherein operating parts 80 is mobilizable is arranged on bracing frame 56, moves between the released position that the locked position coordinated with counterpart and disengagement coordinate with counterpart for impelling locking member 82.
Operating parts 80 is arranged on bracing frame 56 by lock shaft 84 is rotating.In the present embodiment, lock shaft 84 is connected between left and right side plate 64 and 66.
Operating parts 80 has the grip part be arranged in parallel with the axle of lock shaft 84, handled easily person operation and gripping.
In the present embodiment, two actuators 88 are connected with at the two ends of lock shaft 84, and this actuator 88 is arranged between left and right side plate 64 and 66 and relative to the Central Symmetry of lock shaft 84, operating parts 80 impels locking member 82 to move between locked position and released position by actuator 88.
Lock shaft 84 is flat square shafts, and operating parts 80 is provided with flat square hole 86, and operating parts 80 is fixed together with lock shaft 84 by flat square hole 86, and is arranged between left and right side plate 64 and 66.
Equally, actuator 88 is also provided with flat square hole 90, actuator 88 is fixed together with lock shaft 84 by flat square hole 90.Certainly, those skilled in the art can learn, operating parts 80 and actuator 88 can rivet or weld together, can certainly the one-body molded operating parts as driving locking member 82.
In the present embodiment, retaining mechanism 78 comprises two symmetrically arranged locking members 82, and this retaining mechanism 78 comprises two connecting rods 92 further, and connecting rod 92 is for connecting locking member 82 and actuator 88.In the present embodiment, connecting rod 92 is roughly arc, and arcuate structure can play cushioning effect, is convenient to manufacture and rotate.Certainly, connecting rod 92 also can be straight-bar or other form.
The first end of connecting rod 92 is connected with actuator 88 pivotable by the first pin 94; Second end of connecting rod 92 is connected with locking member 82 by the second pin 96.When operating parts 80 around lock shaft 84 axis rotate time, actuator 88 drives connecting rod 92 to rotate, thus changes the distance between the second pin 96 and the axis of lock shaft 84.
As shown in Figure 9, the connecting plate 68 of bracing frame 56 is provided with the gathering sill 98 of longitudinally extension, and this gathering sill 98 is for accommodating locking member 82.When operating parts 80 around lock shaft 84 axis rotate time, change the distance between the second pin 96 and the axis of lock shaft 84, thus impel locking member 82 moving between the locked position and the released position of the part that disengages of counterpart along the bearing of trend of gathering sill 98.So, the rotation of operating parts 80 converts the Linear-moving of locking member 82 to.
Counterpart is be arranged on the mating groove on connector 54.In the present embodiment, as shown in Figure 3, one of them coordinates with two mating grooves 83 of corresponding side respectively to be simultaneously provided with two mating grooves, 83, two locking members 82 in the both sides correspondence of connector 54, thus bracing frame 56 can be fixed in predetermined operating position relative to connector 54.Certainly, the number of this mating groove 83 should be equal to or greater than predetermined operating position.
When bracing frame 56 turns to predetermined operating position around the second axis 67, rotary operating member 80, the distance of the axis of the second pin 96 and lock shaft 84 is strengthened, promotion locking member 82 moves to along the bearing of trend of gathering sill 98 locked position inserting mating groove 83, as shown in Figure 9, thus bracing frame 56 is in locking state, at this moment the butting section 81 of operating parts 80 is resisted against on bracing frame 56.At this locking state, the friction between locking member 82 and mating groove 83 impels operating parts 80 to keep stable.
Correspondingly, as shown in Figure 10, rotary operating member 80 in the other direction, make to be positioned at the second fixed position, the grip part of operating parts 80 and lock shaft 84 generally within same level, the distance so furthered between the second pin 96 and the axis of lock shaft 84, thus released position locking member 82 being moved to the groove 83 that disengages along the bearing of trend of gathering sill 98, thus bracing frame 56 branches to releasing orientation, it can freely rotate by opposite joints 54.At this releasing orientation, the friction between locking member 82 and gathering sill 98 impels operating parts 80 to keep stable; So, rotating operation part 80 is only needed just can easily to be changed between locking state and releasing orientation by bracing frame 56, and without the need to using other structure that operating parts 80 just can be made to keep stable at this two states.
Certainly, if retaining mechanism 78 only comprises the locking member 82, mating groove 83 and the actuator 88 that are arranged on bracing frame 56 side, effect bracing frame 56 being locked at connector 54 can equally also be realized.
