Description
Technical field
The invention relates to a kind of damping device, be meant a kind of damping device that can be applicable to a scroll saw machine (scroll saw) especially.
Background technology
See also Fig. 1, Fig. 1 is the schematic diagram of existing scroll saw machine 10.Existing scroll saw machine comprises a main body 12, a support 14, a platform 16, a saw blade 18, a drive unit 20 and a segment 22.Support 14 is installed in main body 12, has a upper arm 24 and a underarm 26; Platform 16 is installed in main body 12, between upper arm 24 and underarm 26, is suitable for carrying a workpiece (figure does not show); Saw blade 18 is installed in upper arm 24 and underarm 26, passes platform 16; Drive unit 20 is installed in main body 12, is suitable for driving upper arm 24 and underarm 26 and synchronously reaches motion down up, causes saw blade 18 to move up and down, and has a motor 28; Extent of vibration when segment 22 operates in order to reduce existing scroll saw machine 10 on above-below direction.
See also Fig. 2, Fig. 2 is along the cutaway view of 1-1 line among Fig. 1.Drive unit 20 also has a rotating shaft 30 and a fixed block 32, rotating shaft 30 affixed fixed blocks 32, the affixed rotating shaft 30 of a top ends of segment 22.Existing scroll saw machine 10 also comprises a drivening piece 34, and the one end articulates fixed block 32 by a pivotal axis 36, and the other end articulates underarm 26, the also affixed fixed block 32 of pivotal axis 36, and its axle center 38 is the axial lines 40 that depart from rotating shaft 30.
See also Fig. 1 and Fig. 2, motor 28 is in order to drive rotating shaft 30 rotations, when rotating shaft 30 rotations, to order about segment 22 rotations and pivotal axis 36 and be the displacement of round ground, pivotal axis 36 also passes through drivening piece 34 interlock underarms 26, cause support 14 on above-below direction, to move back and forth, cause saw blade 18 to move up and down, but and this workpiece of sawing.Because the position of centre of gravity of segment 22 and 38 positions, axle center of pivotal axis 36 are opposite, when one is positioned at the top of axial line 40 of rotating shaft 30, its another be located in the below of the axial line 40 of rotating shaft 30, cause support 14 in motion on the above-below direction and segment 22 reverse movement on above-below direction, therefore the motion of segment 22 on above-below direction can reduce the extent of vibration that moves up and down and produced because of support 14, but segment 22 has increased the extent of vibration of existing scroll saw machine 10 on left and right directions in the motion on the left and right directions.
For solving the problem that above-mentioned segment 22 has increased the extent of vibration of existing scroll saw machine 10 on left and right directions, a damping device 50 of another existing scroll saw machine is provided, and sees also Fig. 3, and Fig. 3 is the three-dimensional exploded view of the damping device 50 of this another existing scroll saw machine.The direction of motion that the damping device 50 of this another existing scroll saw machine comprises two segments, 52, two segments 52 is opposite, and therefore the vibration on the left and right directions that causes separately of two segments 52 will roughly be offseted.
Yet, for reaching good damping effect, the segment 22 of above-mentioned arbitrary existing scroll saw machine, the weight and the position in this existing scroll saw machine thereof of the necessary corresponding ㄈ frame shape 14 in 52 weight and the position in this existing scroll saw machine thereof, but when actual a large amount of manufacturings should have the scroll saw machine now, the weight of the ㄈ frame shape 14 of this each existing scroll saw machine and installation position be deviation to some extent, if must be at the segment 22 of the special correspondence of each existing scroll saw machine, 52, then too the trouble, and on economic benefit is considered with infeasible.
Summary of the invention
