DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-3 showing an embodiment of the workpiece positioning structure 1 of a laser-cutting/carving machine 2 of the present invention. The structure 1 is for using on a working platform 21 of the machine 2, comprising a fixing seat 11, at least a flexible connecting rod 12 and an indicator 13 to provide laser light spot.
The fixing seat 11 is connected onto the working platform 21 of the machine 2, and the fixing seat 11 is provided thereon with a power supplying means 111 to supply electric power for the indicator 13.
One end of each of the at least one flexible connecting rod 12 is disposed on the fixing seat 11. The number of the connecting rods 12 in this embodiment is two (for example). Both of them are disposed on the fixing seat 11.
The indicator 13 to provide laser light spot is detachably connected to the connecting rods 12; when adjusting the connecting rods 12, the laser spot emitted from the indicator 13 can be projected onto a precise position on the working platform 21.
In use, referring to FIGS. 2-4, firstly the workpiece positioning structure 1 having been assembled is disposed at one of various positions on the working platform 21 of the machine 2 according to requirement. When in carving and cutting operation, a user can adjust the connecting rods 12 at will to render the laser spot emitted from the indicator 13 on the connecting rods 12 to be projected onto a precise position on the working platform 21. The workpiece can thus be fast and accurately put in the position where the laser spot is to irradiate at. This can increase the effect of positioning a workpiece of soft material.
Therefore, the present invention has the following advantages:
- 1. The present invention takes advantage of the design of laser spot positioning to make a user fast and surely discriminate a position and place a workpiece immediately in position. It is very convenient and effective.
- 2. The workpiece positioning structure of a laser-cutting/carving machine of the present invention takes advantage of the design of a flexible connecting rod to acquire a wide angular rotating range for projection of laser spot, and the structure is simple, convenient in use and adjustment.
In conclusion, according to the above statement and drawings attached, the present invention surely can reach the expected objective to provide a workpiece positioning structure of a laser-cutting/carving machine, which is simple, and convenient in use and adjustment.
The embodiment is only for illustrating the present invention, and not for giving any limitation to the scope of the present invention. It will be apparent to those skilled in this art that various equivalent modifications or changes could be made without departing from the spirit of this invention.
