Detailed description of the invention
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be elaborated.
As shown in Figure 1, for using the band sawing machine 10 of saw band tension adjustment mechanism 20 of a preferred embodiment of the present invention, band sawing machine 10 shown in figure consists predominantly of pedestal 11 on, once the saw band 15 of driving wheel 14 and driven pulley 13 is located at driven pulley in pedestal 11 13, and is located at driving wheel in lower pedestal 12 14, and is set around by pedestal 12,, and one is located at lower pedestal 12 and connects the motor 16 of driving wheel 14.Please coordinate with reference to Fig. 2 and Fig. 3, saw band tension adjustment mechanism 20 of the present invention is located at pedestal 11 and is had a holder 30, an elevating bracket 40, and a Control Component 50.
Holder 30 is fixed on pedestal 11 and has one first fixed block 32 and 2 second fixed block 34, two second fixed blocks 34 relatively lock in the two sides of the first fixed block 32.
Elevating bracket 40 has two relative axostylus axostyle 41, a top board 42, a base plate 43, wheel seats 44, wherein: two axostylus axostyles 41 are arranged in the first fixed block 32 of holder 30 and can move up and down along the axially relative holder 30 of itself.Top board 42 and base plate 43 are connected to top, the two ends, the end of two axostylus axostyles 41, and top board 42 and base plate 43 can be moved along with two axostylus axostyles 41.Wheel seat 44 is sheathed to be fixed on two axostylus axostyles 41 and between top board 42 and base plate 43, to be pivoted for confession driven pulley 13.Thus, elevating bracket 40 can be risen or be declined by the synchronous relative holder 30 of driven pulley 13 that drives of wheel seat 44.
Control Component 50 has leader 51 and a cam bit 52, and the sheathed rotating shaft 512 of being fixed on handle 51 of cam bit 52, can rotate by the driving of handle 51 cam bit 52 relative to elevating bracket 40.Cam bit 52 has a large-diameter portion 522 and a minor diameter part 524, as shown in Figures 3 to 5, minor diameter part 524 wherein has one against plane 526, in addition, cam bit 52 is provided with a stop part 53, stop part 53 protrudes from the surface of cam bit 52, and locating effect is provided for the top board 42 of butt elevating bracket 40.
In the time will dismantling saw band 15, first down cam bit 52 is turned to an off-position P1 by pulling handle 51, as shown in Fig. 3 and Fig. 5, elevating bracket now 40 can because weight own drop to be resisted against cam bit 52 minor diameter part 524 against plane 526, make driven pulley 13 to shorten the distance between driving wheel 14 along with the decline of wheel seat 44, thus, saw band 15 just can present lax state, carries out the dismounting of saw band 15 in order to operating personnel.
On the contrary, in the time will saw band 15 being installed, be that handle 51 is up pulled, make cam bit 52 turn to a packing position P2, as shown in Figures 3 and 4, stop part 53 now can be connected to the top board 42 of elevating bracket 40 and the location that completes cam bit 52, simultaneously elevating bracket 40 can be subject to cam bit 52 large-diameter portion 522 ejection and on lift, and synchronously drive driven pulley 13 away from driving wheel 14 by wheel seat 44 in upper process of lifting, in the case, saw band 15 can be presented the state of tightening by driven pulley 13 supports, to carry out sawing operation.
In addition, for the tension adjustment of saw band 15 is arrived to suitable elasticity, saw band tension adjustment mechanism 20 of the present invention more provides a trimming assembly 60, trimming assembly 60 has a supporting plate 61, a helical spring 62, a nut 63, an adjusting lever 64, a thrust bearing 65, an and runner 66, as shown in Figure 3 and Figure 6, wherein:
Supporting plate 61 is folded between two axostylus axostyles 41 of elevating bracket 40 and between wheel seat 44 and base plate 43, helical spring 62 is located between the wheel seat 44 of supporting plate 61 and elevating bracket 40; Nut 63 is fixed on the base plate 43 of elevating bracket 40; Adjusting lever 64 is arranged in the base plate 43 of supporting plate 61 and elevating bracket 40 rotationally, and stretches in helical spring 62 with its one end, and adjusting lever 64 has a threaded portion 642, establishes nut 63 for spiral shell; Thrust bearing 65 is sheathed on adjusting lever 64 and is connected to the bottom surface of supporting plate 61; Runner 66 is fixed on one end of adjusting lever 64 and exposes to outside pedestal 11, for driving adjusting lever 64 to rotate.
In the time of operation, drive adjusting lever 64 to rotate by runner 66, because nut 63 maintains static, so adjusting lever 64 meetings are axially up moved along itself, and up promote supporting plate 61 by thrust bearing 65 in mobile process, then supporting plate 61 meeting extrusion spiral springs 62, extruded helical spring 62 is understood up ejection wheel seat 44 again, driven pulley 13 is up moved, as shown in Figure 6, to reach the effect of fine setting elasticity.
It should be added that at this, for limit wheel seat 44 on move, elevating bracket 40 also has two spacing rings 45, each spacing ring 45 is fixed on axostylus axostyle 41 and between top board 42 and wheel seat 44, be used for stopping wheel seat 44, make wheel seat 44 in the time being subject to the promotion of helical spring 62, can only produce trace mobile.In addition, elevating bracket 40 also has a tension force pointer 46, tension force pointer 46 is hubbed at pedestal 11 and has a chute 462 in its one end, supporting plate 61 has a protruding axle 612, for being inserted in the chute 462 of tension force pointer 46 slippingly, make tension force pointer 46 to produce pivotable along with moving up and down of supporting plate 61, for coordinating a sight scale division (not shown) to indicate the elasticity of current saw band 15.
In sum, the elevating bracket 40 that saw band tension adjustment mechanism 20 of the present invention provides is to produce movement by two axostylus axostyles 41, has better structural strength and operational stability, to reach object of the present invention than commonly using the slide that Patent Case uses.
Finally, the composed component that the present invention disclosed in the aforementioned embodiment, only for illustrating, is not used for limiting the scope of patent protection of this case, and substituting or changing of other equivalence elements, also should be contained by the scope of patent protection of this case.
