Detailed description of the invention
Now lift following example and combine accompanying drawing structure and effect of the present invention are described in detail.
As it is shown in figure 1, the band sawing machine 10 of the saw band tension adjustment mechanism 20 for using a preferred embodiment of the present invention, in figure
The driven pulley 13, one that shown band sawing machine 10 consists predominantly of pedestal 11 on, once pedestal 12, is located in pedestal 11 sets
Drivewheel 14, one in lower pedestal 12 is set around the saw band 15 of drivewheel 14 and driven pulley 13, and one is located at lower pedestal 12
And connect the motor 16 of drivewheel 14.Please coordinate with reference to Fig. 2 and Fig. 3, the saw band tension adjustment mechanism 20 of the present invention is located at and is appeared on the stage
Seat 11 and have and fix seat 30, elevating bracket 40, and one controls assembly 50.
Fixing seat 30 is fixed on pedestal 11 and has one first fixed block 32 and 2 second fixed blocks 34, and two second fix
Block 34 relatively locks in the two sides of the first fixed block 32.
Elevating bracket 40 has two relative axostylus axostyle 41, top board 42, base plate 43, wheel seats 44, wherein: two axostylus axostyles 41 are worn
It is located at the first fixed block 32 of fixing seat 30 and can move up and down along the axially opposing fixing seat 30 of itself.Top board 42 and base plate
43 are connected to the top of two axostylus axostyles 41, two ends, the end so that top board 42 and base plate 43 can move along with two axostylus axostyles 41.Wheel seat 44 overlaps
If being fixed on two axostylus axostyles 41 and between top board 42 and base plate 43, for being pivoted for driven pulley 13.Thus, elevating bracket 40 is permissible
Synchronize to drive driven pulley 13 to be relatively fixed seat 30 by wheel seat 44 to rise or fall.
Control assembly 50 and there is leader 51 and a cam bit 52, the sheathed rotating shaft being fixed on handle 51 of cam bit 52
512 so that cam bit 52 can OQ t seat 40 rotates by the driving of handle 51.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 therein has one against plane 526, additionally, cam bit
52 are provided with a stop part 53, and stop part 53 protrudes from the surface of cam bit 52, for abutting the top board 42 of elevating bracket 40 and providing
Locating effect.
When saw band 15 to be dismantled, the most down cam bit 52 is turned to an off-position P1 by pulling handle 51, such as Fig. 3
And shown in Fig. 5, elevating bracket 40 now can because weight own drop to be resisted against the minor diameter part 524 of cam bit 52 against flat
Face 526 so that driven pulley 13 can shorten the distance between drivewheel 14 along with the decline of wheel seat 44, consequently, it is possible to saw band
15 will present lax state, carry out the dismounting of saw band 15 in order to operator.
On the contrary, be then up to be pulled by handle 51 when saw band 15 to be installed, cam bit 52 is made to turn to a packing position
Putting 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 complete determining of cam bit 52
Position, simultaneously elevating bracket 40 can by the pushing and withstanding of the large-diameter portion 522 of cam bit 52 on lift, and pass through wheel seat during upper lifting
44 synchronize to drive driven pulleys 13 away from drivewheel 14, and in the case, saw band 15 can be presented by driven pulley 13 support to be tightened
State, in order to carry out sawing operation.
In addition, in order to by the tension adjustment of saw band 15 to suitable elasticity, the saw band tension adjustment machine of the present invention
Structure 20 more provides a trimming assembly 60, and trimming assembly 60 has supporting plate 61, helical spring 62, nut 63, adjusting lever
64, a thrust bearing 65, and a 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
It 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 rotatable
Be arranged in the base plate 43 of supporting plate 61 and elevating bracket 40, and stretch in helical spring 62 with its one end, adjusting lever 64 has one
Threaded portion 642, sets 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
It is fixed on one end of adjusting lever 64 and exposes to outside pedestal 11, being used for driving adjusting lever 64 to rotate.
When operation, adjusting lever 64 is driven to rotate by runner 66, because nut 63 maintains static, so adjusting lever 64 meeting
Axially up moving along itself, and up promote supporting plate 61, then supporting plate 61 by thrust bearing 65 during movement
Meeting extrusion spiral spring 62, extruded helical spring 62 meeting the most up pushing and withstanding wheel seat 44, make driven pulley 13 up move, such as figure
Shown in 6, to reach to finely tune the effect of elasticity.
It should be added that at this, in order to limit the upper shifting of wheel seat 44, elevating bracket 40 also has two spacing rings 45, respectively
Spacing ring 45 is fixed on axostylus axostyle 41 and between top board 42 and wheel seat 44, is used for stopping wheel seat 44, makes wheel seat 44 by spiral shell
Trace can only be produced when revolving the promotion of spring 62 to move.Additionally, elevating bracket 40 also has a tension force pointer 46, tension force pointer 46 pivot
Being located at pedestal 11 and have a chute 462 in its one end, supporting plate 61 has a protruding shaft 612, is inserted in for slippingly and opens
In the chute 462 of power pointer 46 so that tension force pointer 46 can produce pivot along with moving up and down of supporting plate 61, is used for coordinating
One sight scale division (not shown) indicates the elasticity of current saw band 15.
In sum, the elevating bracket 40 that the saw band tension adjustment mechanism 20 of the present invention is provided is by two axostylus axostyles 41
Producing mobile, the slide used compared to existing Patent Case has more preferable structural strength and operational stability, to reach this
The purpose of invention.
Finally, the composed component that the present invention is disclosed in the aforementioned embodiment, by way of example only, not it is used for limiting this
The scope of patent protection of case, the replacement of other equivalence elements or change, also should be contained by the scope of patent protection of this case.
