Referring to FIGS. 1 to 6, the cover device 1 for a machine tool according to the present embodiment allows a worker to inspect an automatic tool changer (ATC), move the entire machine tool, or move to a specific location. In order to solve the inconvenience of loading due to the length in the width direction conveniently when loading in a storage space such as a container for storage, the cover part is detachably changed to have improved mobility.

To this end, in this embodiment, the cover part 100 installed on the outside of the automatic tool changer (ATC) provided in the main body part 10 and the cover part 100 are in rolling contact along the bottom surface so as to be movable. It includes a moving part 200 provided in and a mounting part 300 provided so that the cover part 100 is detachable from the main body part 10 .

An automatic tool changer (ATC) is provided inside the body part 10 , and a plurality of unit covers 50 are installed on the body part 10 together with the cover part 100 .

The cover part 100 is assembled together with the unit cover 50, and the unit cover 50 is adjacent to the side surface excluding the place where the cover part 100 is installed, together with the cover part 100. bonded to each other For reference, the unit cover 50 is disposed at left and right positions of the cover unit 100, but may also be disposed at other positions.

The cover unit 100 is detachably installed on the front of the automatic tool changer (ATC), and the unit cover 50 is not separated after being installed once on the body unit 10 and is initially installed. It stays on.

The cover part 100 can be conveniently separated at the time of shipment after the machine tool is assembled, reducing the length in the width direction so that it can be more easily stored in a limited space such as a container, thereby improving the convenience and efficiency of loading. do.

When the cover part 100 is separated from the body part 10, the length L1 in the longitudinal direction is maintained, but the length L2 in the width direction can be reduced from L2_B to L2, so that the cover part 100 in the width direction is reduced by the volume occupied by

Therefore, the convenience of loading according to the attachment and detachment of the cover unit 100 is greatly improved.

The cover part 100 according to the present embodiment has a front part 110 spaced outwardly while looking at the automatic tool changer (ATC), and both left and right sides of the front part 110 are the automatic tool changer ( ATC), and includes a side portion 120 having a contact portion 112 formed in surface contact with the unit cover 50 installed on the main body portion 10.

The front part 110 and the side part 120 may be variously changed without being limited to the form shown in the drawings, and are not particularly limited to a specific form.

The side part 120 is provided with an inspection window (W) for visually checking whether or not there is an abnormality in the automatic tool changer (ATC), so that the operator can inspect it on site or if a problem occurs, it is possible to visually check first. .

The side part 120 is detachably coupled through a mounting part 300 to be described later in a state in which the contact part 112 is in surface contact with the unit cover 50 as shown in the drawing.

For example, the movable part 200 may use a caster provided at the lower corner of the cover part 100 and provided at the end of the extension part 210, but may be substituted with another configuration capable of rolling contact. It could be possible.

The extension part 210 has a predetermined length, extends downward from each corner of the cover part 100, and has a polygonal structure of more than a square, for example, so that the above-described movable part 200 can be easily installed. It can be done.

The moving part 200 is composed of a wheel, a support bracket to which the wheel is installed and fixed to the lower end of the extension part 210, and includes a locking part (not shown) for fixing.

Since the cover part 100 can be fixed in position through a locking part after being moved along the bottom surface, further movement is restricted, so that the movement is stably prevented after the cover part 100 is moved to a desired position by the operator. This can prevent loss or damage due to additional movement.

The moving unit 200 according to this embodiment is provided with a damper 202 for absorbing impact transmitted from the floor. Although a coil spring is used for the damper 202, it may be possible to change to a different configuration in order to reduce an impact transmitted to the cover part 100 through the bottom surface.

Since one end of the damper 202 is supported on the upper surface of the caster and the other end is supported on the lower surface of the extension part 210, the damper 202 absorbs the impact transmitted in the vertical direction through the moving part 200 and covers the cover part 100.

The mounting part 300 according to the present embodiment is maintained in a coupled state from the contact part 112 toward the unit cover 50 in different directions.

In the mounting part 300, when the cover part 100 is viewed from the outside, the side part 120 located on the right side is coupled in the direction of looking at the body part 10, and the unit cover 50 is viewed at the left position. As coupling is made in the direction, coupling is made in different directions.

As a result, when the cover part 100 is coupled to the main body part 10 through the mounting part 300, the coupling force can be improved, so that separation during processing of the workpiece is prevented.

As an example, a plurality of coupling bolts coupled to the unit cover 50 may be used as the mounting portion 300 according to the present embodiment.

Since the coupling bolts are ordinary bolts, the installation cost is low and cost reduction is possible, and special equipment for assembling to the cover part 100 is not required, making it possible to easily install it in the field.

The coupling bolt is coupled via the unit cover 50 at the contact portion 112 as shown in enlarged views C1 and C2. The unit cover 50 has a mounting portion M formed so that the coupling bolts can be stably screwed together, so that the coupling bolts can be stably engaged or disengaged.

Referring to FIG. 6, the mounting part 300 according to the present embodiment is provided on the first magnetic body 310 provided on the unit cover 50 together with the coupling bolt, and on the mounting part 300, A second magnetic body 320 having a polarity different from that of the first magnetic body 310 is included.

When the mounting part 300 is used by using the easy attachment/detachment principle of the magnet in consideration of the operator's more convenient workability, the cover part 100 can be separated more quickly and conveniently, thereby improving convenience.

For example, the coupling bolts are coupled at upper and lower positions of the side part 120 , and the second magnetic body 320 is disposed at an intermediate position of the side part 120 .

In order for the cover part 100 to maintain a stable coupling state with the unit cover 50, since the coupling bolts are coupled to the upper and lower sides of the side portion 120 at least, the stability is improved, so the coupling bolt and the second magnetic body 320 By combining, it is possible to promote stable attachment and detachment of the cover unit 100 .

For example, the first magnetic body 310 uses a magnet having an N pole and the second magnetic body 320 uses a magnet having an S pole, so that the second magnetic body 320 easily contacts the first magnetic body 310. Or contact can be released. For reference, the polarities of the first and second magnetic bodies 310 and 320 can be changed and are not particularly limited to a specific polarity.

Since the first magnetic body 310 is stably fixed so as not to be separated from the unit cover 50, and the second magnetic body 320 is also stably fixed so as not to be separated from the contact part 112, they can be contacted or released from each other. The occurrence of breakage or breakage can be minimized.

In this way, the cover part 100 can be easily attached to and detached from the unit cover 50 via the mounting part 300, so that in the case of requiring repair at the work site or moving to a repair center for repair, the cover part Convenience is improved because the movement is performed after separating the 100.

A cover device for a machine tool according to a second embodiment of the present invention will be described with reference to the drawings. For reference, the second embodiment is configured in a part similar to the first embodiment, and the configuration of the second mounting part is more specific.

It includes a side part 120 that is bent and has a contact part 112 formed in surface contact with the unit cover 50 installed on the main body part 10 .

For the first mounting part 3100, for example, a plurality of coupling bolts coupled to the bolt unit cover 50 may be used, and are installed on the upper and lower sides of the contact part 112, and the second mounting part 3200 is disposed at the other positions. This reduces the hassle of the operator releasing the plurality of coupling bolts one by one.

Since the coupling bolts are ordinary bolts, the installation cost is low and cost reduction is possible, and special equipment for assembling to the cover part 100 is not required, making it possible to easily install it in the field.

The second mounting part 3200 according to the present embodiment includes a clamp 3210 rotatably installed toward the opening 112a opened in the contact part 112 and the clamp 3210 to be inserted into the opening 112a. It includes a magnet 3220 located on the front side.

Since the clamp 3210 is installed via the hinge part 3212 so as to be rotatable at a predetermined angle in the opening part 112a, an operator can easily attach the cover part 100 to the clamp 3210.

The clamp 3210 is provided with a bent portion 3214 that is bent outward so that a worker can pull it with a finger or easily move it in the direction in which the first mounting portion 3100 is located.

The bent portion 3214 may be variously changed, such as the shape shown in the drawings or the ring shape, and is not particularly limited to a specific shape.

The first mounting part 3100 is first released by the operator, and when the cover part 100 is to be separated from the unit cover 50 and the bent part 3214 is pulled in the A direction, the magnet 3220 is the unit cover. As the surface contact is released at 50, the adhesive force with the unit cover 50 is released.

The operator can easily release the coupled state of the cover part 100 attached to the unit cover 50 by pulling the plurality of second mounting parts 3200 in the A direction in the same way as described above.

Contrary to this, when the clamp 3210 is moved in the B direction, the magnet 3220 is inserted through the opening 112a and remains attached to the unit cover 50, so that the cover part 100 can be easily requested. It can be done.

Although the second mounting part 3200 is limited to the one where the magnet 3220 is provided at the above-mentioned position, the magnet 3220 and the magnet 3220 are placed on the opposite surface facing the front surface of the clamp 3210 on the unit cover 50. It may also be possible to have an auxiliary magnet with a different polarity provided.

For example, the magnet 3220 may be configured as a protrusion 3222 curved toward the opening 112a or protruded toward the unit cover 50 in a concavo-convex shape.

The protruding portion 3222 may be used in any one of a straight line shape, a cross shape, or a polygonal shape, or may be used together, and is not particularly limited to a specific shape.

When the protrusion 3222 of the magnet 3220 is formed, it is possible to easily release the contact surface to which the magnet 3220 is in close contact with the unit cover 50 while stably securing it. The force required to separate from the cover 50 is minimized.

Therefore, the operator can more easily attach and detach the cover part 100 from the unit cover 50 using the second mounting part 3220 .

In the above, one embodiment of the present invention has been described, but those skilled in the art can add, change, delete, or add components within the scope not departing from the spirit of the present invention described in the claims.
