Abstract
A circular sawing machine includes a base, a saw seat movable relative to the base, and a link mechanism pivotally mounted between the base and the saw seat, so that the saw seat is linearly movable relative to the base. Thus, the link mechanism can absorb vibration or shock during operation of the circular saw blade so as to provide a shock-absorbing effect the circular saw blade, so that the circular saw blade can be operated smoothly and stably.
Claims12
A circular sawing machine, comprising:
- a base;
- a saw seat movable relative to the base;
- and
- a link mechanism pivotally mounted between the base and the saw seat, so that the saw seat is linearly movable relative to the base, the link mechanism has a symmetrical structure so that the saw seat can be moved linearly relative to the base by linear movement of the link mechanism, the link mechanism including a positioning seat secured on the base, two symmetrically opposite first links each having a first end mounted on the positioning seat two symmetrically opposite second links each having a first end pivotally mounted on a second end of a respective one of the two first links, and two symmetrically opposite third links each having a first end pivotally mounted on a second end of a respective one of the two second links and a second end pivotally mounted on a connecting seat which is mounted on the saw seat, wherein:
- the two first links are arranged in a substantially V-shaped manner;
- the two second links are arranged in a substantially V-shaped manner;
- the two third links are arranged in a substantially V-shaped manner;
- and
- the connecting seat is substantially V-shaped.
