An enlarged structural diagram of an initial driving force providing module, which is a D region.

Referring to these drawings, the automatic opening and closing device for the door of the machine tool of the present embodiment is to open and close the door (120) automatically in various types of machine tools, the door rail 130, The hinge module 140, the cylinder 150, and the initial driving force providing module 160 may be included.

The machine tool shown in FIG. 1 may be various, such as a turning center, a machining center, a door machining center, a swiss turn, an electric discharge machine, a horizontal NC boring machine, and the like.

Such a machine tool is provided with an exterior cabinet 110 forming an exterior, and one side of the exterior cabinet 110 slides one side of the exterior cabinet 110 to open and close for access in the exterior cabinet 110. The door 120 is provided.

A plurality of rollers 121 for sliding movement are provided at the lower end of the door 120. The roller 121 is seated on the door rail 130 and slides along the door rail 130. At this time, as shown in FIG. 7, the roller 121 is not separated from the door rail 130. It may be manufactured in a form of slightly covering the door rail 130.

By having the structure as shown in FIG. 7, the roller 121 is not detached from the door rail 130 even when the door rail 130 is moved up and down slightly up / down.

The door rail 130 is provided below the door 120 in a direction in which the door 120 is opened and closed to support the sliding movement of the roller 121 provided in the door 120.

The door rail 130, which may have a rod shape, may be provided to have a size longer than that of the door 120.

As shown in FIGS. 2 to 4 and 7, the hinge module 140 is coupled to one side of the door rail 130 to form a rotation axis of the door rail 130.

The hinge module 140 is coupled to the shaft hole 141 formed in the door rail 130 to form a urethane bushing 142 and the shaft hole 141 region to form a rotation axis of the door rail 130. And a fixing bolt 143 for fixing the bushing 142.

By using the urethane bushing 142, the sliding motion of the door rail 130 can be induced smoothly, and durability can be improved. In the structure of the hinge module 140, the door rail 130 may move smoothly by preventing the fixing bolt 143 and the door rail 130 from touching by the length of the shaft hole 141.

The cylinder 150 is connected to the exterior cabinet 110 and the door rail 130 at the other side of the door rail 130 opposite to the hinge module 140.

The cylinder 150 drives the door rail 130 up / down with the hinge module 140 as the axis of rotation so that the door 120 slides by gravity by tilting the door rail 130. It plays a role.

In the preferred embodiment of the present invention, even if the door 120 is enlarged, the door 120 may be slid by only a simple cylinder 150 without using the large cylinder 3 as in FIG. 1.

In another preferred embodiment of the present invention as shown in FIGS. 5 and 6, this cylinder 150 has a cylinder body 151 coupled to the exterior cabinet 110 by a first bracket B1, and a second one. It is coupled to the door rail 130 by the bracket (B2), it may include a cylinder rod 152 is extended or reduced in length with respect to the cylinder body 151.

Looking at the operation, as shown in FIGS. 3 and 5 when the cylinder 150 is extended to extend the length of the cylinder rod 152, the other side of the door rail 130 with respect to the hinge module 140 as the door rail 130 is raised This is inclined, through which the door 120 is moved in the direction of the arrow by gravity (self-weight) to open the exterior cabinet 110.

On the contrary, when the length of the cylinder rod 152 is reduced by driving the cylinder 150 as shown in FIGS. 4 and 6, the door rail 130 is reversed while the other side of the door rail 130 is lowered with respect to the hinge module 140. The door 120 is moved in the direction of the arrow by gravity (self-weight) and thereby closes the exterior cabinet 110.

When the door 120 is opened and closed using the force of gravity as described above, it is not necessary to use a large cylinder (see FIG. 1) as in the prior art, and it is possible to reduce the cost as well as to restrict the installation space.

In addition, even if the door 120 is enlarged, the door 120 may be automatically opened and closed efficiently without changing the layout of the equipment.

The initial driving force providing module 160 is coupled to one side of the door 120 and serves to provide the initial driving force for the exterior cabinet 110 when the door 120 is opened.

As shown in FIG. 8, the initial driving force providing module 160 is connected to the module shaft 161 coupled to one side of the door 120 and the module shaft 161, and is compressed when the door 120 is closed. In addition, when the door 120 is opened, the elastic member 162 is expanded by an elastic force and provides an initial driving force, and a snap ring 163 coupled to the module shaft 161 to support the elastic member 162.

Since the initial driving force providing module 160 serves to provide a constant force in the direction in which the door 120 is opened by the elastic force by the elastic member 162 at the initial position that the door 120 is opened, the door 120 To make it easier to open.

According to the present invention having such a structure and operation, regardless of the opening width of the door 120, a small size of the cylinder 150 can be used, not only free of constraints of the installation space, but also reduce the cost, and also the door Even if 120 is enlarged, the door 120 can be automatically opened and closed efficiently without changing the layout of the equipment.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
