Improve work efficiency, reduce the working strength of operator；Rotating spanner, makes cam be resisted against near one end of axis and executes
On belling platform, work head is pressed on installation base by platen, and now, big swing angle multifunctional saw can normally use；Work as needs
When more changing jobs, rotating spanner makes cam be resisted against on pressure boss away from one end of axis, presses under depression bar, and platen is by work
Head unclamps, and convenient being taken off by work head is replaced, and it is convenient to change, it is achieved that the fast assembling-disassembling of work head.
Accompanying drawing explanation
Fig. 1 is big swing angle multifunctional saw schematic diagram；
Fig. 2 is big swing angle multifunctional saw structural representation；
Figure is labeled as: casing 1, eccentric rotor 2, bearing 3, fork 4, output main shaft 5, installation base 51, depression bar 52,
Pressure boss 54, cam 55, spanner 56, work 6.
Detailed description of the invention
With detailed description of the invention, this utility model is illustrated further below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 2, big swing angle multifunctional saw, including casing 1, in casing 1, it is provided with swing output unit, pendulum
Dynamic output unit includes eccentric rotor 2, be arranged on eccentric rotor 2 the bearing 3 on output shaft, the fork 4 being connected with bearing 3
And the output main shaft 5 being connected with fork 4, output main shaft 5 is provided with work 6, the offset of described eccentric rotor 2 is
1～1.6 millimeter；The offset of eccentric rotor 2 is increased to 1～1.6 millimeter so that the pendulum angle of fork 4 increases, angle of oscillation
Degree is 3.5～5 degree；Concrete, the offset that can be off rotor is 1 millimeter, and the pendulum angle of fork 4 is 3.5 degree；Or
It is 1.3 millimeters that person is off the offset of rotor, and the pendulum angle of fork 4 is 4.5 degree；Or the offset of eccentric rotor is
1.6 millimeters, the pendulum angle of fork 4 is 5 degree；Increase the angle swinging output of fork 4, increase the pendulum of work 6
The angle of dynamic output so that the work surface of work 6 is bigger, improves work efficiency, reduces the working strength of operator.
Described bearing is the spherical bearing of 607 cambered surfaces.
