ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a manufacturing machine, in particular a laser machine, of the type comprising a base provided with a horizontal guide on which is slidably mounted a cantilever arm projecting from the base, and wherein the arm carries a second guide, orthogonal to the first guide, along which a manufacturing head is slidably mounted, which in the case of a laser machine is formed by a focusing head.
The applicant has manufactured with great commercial success a machine of this type known with the trademark “Platino 1325” having net work travels of 1300×2500 mm. One of the major advantages of this machine is that it can be transported from the construction site to the installation site without being disassembled. In fact, the maximum transversal dimension of the machine (in the direction of the longitudinal direction of the cantilever arm) is about 2400 mm which is the maximum width admitted by the rules of the road for ordinary road transports. Machine of this type with greater transversal dimension should be disassembled for the transport and would need skilled operators for reassembling and setting up the machine in the installation site, which involves an increase of the transport and installation time and of the cost of the machine.
SUMMARY OF THE INVENTION
The problem on which the present invention is based is to provide a machine with net work travels higher than those of the known machine mentioned above, and which anyhow, can be transported in a monolithic form.
According to the present invention, this object is achieved by virtue of the fact that the arm is connected to the base by means of a hinge with a vertical axis and is movable between a normal operating position and a transport position.
By virtue of this idea of solution, machines can be manufactured with transversal net work travel of 1.5 meters and over, which can be contained into the clearance gauge of ordinary road transports by simply inclining the arm with respect to its normal operating position. On the installation site the arm is fixed in its normal operating position by simple and fast operations which do not need elaborate setting up.
A further advantage of the machine according to the invention consists in that the arm can be easily brought in its inclined position during maintenance operations, for facilitating access to parts of the machine which in traditional solutions can be accessed only with great difficulties.
