Description

Door for machine tool {door for machine tool}

The present invention relates to a door device for a machine tool, and more particularly, to a door device using a set screw and a spacer so as to easily adjust the position of the door main body. The weight of the door main body is not concentrated in the bolt, So that the door main body can be prevented from deviating from the correct position.

Generally, a machine tool for machining a workpiece by rotating a workpiece or a tool at a high speed is provided with a door device for protecting the worker from various safety accidents during operation. Such a door device is structured such that a roller is provided at a lower end portion and is opened and closed by moving to the front and rear half portions on a guide rail provided in the main body.

1 is a configuration diagram of a conventional door device for a machine tool.

1, a conventional door device for a machine tool comprises a door main body 11 installed on a machine tool and opening / closing a work space of the machine tool and having a sloped surface 11a formed at a lower portion thereof, A roller 14 installed on the lower portion of the inclined surface 11a of the main body 11 by using bolts 12 and washers 13 and a roller 14 mounted on the machine tool body 16, And a guide rail 15 for guiding the guide rail.

The operation of the conventional door device for a machine tool according to the above-described configuration is as follows.

The door body 11 is lifted using a crane (not shown) in order to assemble the roller 14 to the door body 11. After the operator holds the door body 11 and adjusts its position, The roller 12 is assembled to the lower portion of the door main body 11 by using the washer 12 and the washer 13.

The position of the door main body 11 is adjusted so that the door main body 11 and the roller 12 are positioned on the guide rail 15 after the assembly of the roller 12 to the door main body 11 is completed do.

However, in the conventional door device for a machine tool as described above, when the door body 11 and the roller 12 are assembled on the guide rail 15, the position of the door body 11 is relatively adjusted There is a difficult problem.

Since the conventional door device for a machine tool supports the door body 11 only by the force of the bolt 12 and the washer 13, the bolt 12 and the washer 13 Is moved in the assembly hole and is loosened, there is a problem that the door main body 11 can escape from the correct position.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a door device for a machine tool capable of easily adjusting a position of a door body using a set screw and a spacer.

It is another object of the present invention to provide a door device for a machine tool capable of preventing the door body from deviating from a predetermined position by allowing the weight of the door body to be dispersed using the set screw and the spacer without concentrating on the bolt.

According to an aspect of the present invention, there is provided a door device comprising: a door main body provided on a machine tool to open and close a work space of a machine tool, A spacer provided on the door main body so as to surround the bolt on the opposite side of the roller body with the door main body therebetween; a spacer provided on the door main body for vertically moving the position of the door main body A set screw, and a guide rail provided on the body of the machine tool for guiding the roller.

The configuration of the present invention is preferably such that when the set screw is loosened, the set screw is raised above the door main body so that the spacer and the roller are raised.

According to the present invention, when the set screw is tightened, the set screw is lowered downward relative to the door main body, so that the spacer and the roller are lowered.

The constitution of the present invention is preferable if the weight of the door body is dispersed through the set screw and the spacer without concentrating on the bolt.

It is preferable that the inclined surface is formed on the mounting hole at the lower portion of the door body.

In the present invention, the position of the door main body can be easily adjusted by using the set screw and the spacer, and the weight of the door main body is dispersed by using the set screw and the spacer without concentrating on the bolt, The present invention has an effect that can be prevented.

2 is a configuration diagram of a door device for a machine tool according to an embodiment of the present invention.
3 is a view showing a state in which a set screw of a door device for a machine tool is loosened according to an embodiment of the present invention.
4 is a view showing a state in which a set screw of a door device for a machine tool is tightened according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention. Other objects, features, and operational advantages, including the purpose, operation, and effect of the present invention will become more apparent from the description of the preferred embodiments.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory only and are not to be construed as limiting the scope of the invention as disclosed in the accompanying claims. It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and similarities, many of which are within the scope of the present invention.

Also, terms and words used in the description and claims of the present invention are defined based on the principle that the inventor can properly define the concept of a term in order to explain its invention in the best way, And should not be construed as limited to only the prior art, and should be construed in a meaning and concept consistent with the technical idea of the present invention. For example, the terms relating to directions are set on the basis of the position represented on the drawing for convenience of explanation.

2 is a configuration diagram of a door device for a machine tool according to an embodiment of the present invention.

2, the door device for a machine tool according to an embodiment of the present invention is installed in a machine tool to open and close a work space of a machine tool, and has an inclined surface 21a formed at a lower portion thereof, A door main body 21 in which a mounting hole 21b is formed in a lower portion of the door main body 21a and a roller 24 installed in the lower part of the inclined surface 21a of the door main body 21 using bolts 22. [ A spacer 23 provided to surround the bolt 22 on the opposite side of the roller 24 with the door main body 11 interposed therebetween and a spacer 23 provided on the door body 21 for supporting the spacer 23 A set screw 27 for moving the position of the door main body 21 upward and downward and a guide rail 25 provided on the machine tool main body and guiding the roller 24.

The operation of the door device for a machine tool according to an embodiment of the present invention will now be described.

The door body 21 is lifted by using a crane (not shown) to assemble the roller 24 to the door body 21 and then the operator adjusts the position by holding the door body 21, The roller 22 is assembled to the lower portion of the door main body 21 by using the above-

The position of the door main body 21 is adjusted so that the door main body 21 and the roller 22 are positioned on the guide rail 25 At this time, the operator adjusts the position by loosening or tightening the set screw 27 to relatively move the position of the door main body 21 up and down.

3 shows the state in which the set screw 27 is loosened so that when the set screw 27 is loosened, the set screw 27 is lifted up relative to the door main body 21, The door 24 is raised in the direction of the arrow on the mounting hole 21b so that the door body 21 relatively descends.

4 shows a state in which the set screw 27 is tightened. When the set screw 27 is tightened, the set screw 27 is lowered downward relative to the door main body 21, The roller 24 is lowered in the direction of the arrow on the mounting hole 21b so that the door body 21 relatively rises.

Therefore, it is possible to easily adjust the position of the door main body 21 by using the set screw 27 and the spacer 23.

On the other hand, since the weight of the door body 21 is dispersed by using the set screw 27 and the spacer 23 without being concentrated on the bolt 22, it is possible to prevent the door body 21 from deviating from the correct position .
