DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an attachment storage device for a machine tool such as a plano milling machine.

The machine tool 30 such as a plano mirror is, for example, a first
As shown in the figure, there is a bed 31 that is long in the front and back direction, a table 32 that is placed on top of the bed 32 and that reciprocates back and forth, columns 33 that stand up on both sides of the bed 31, and both columns. 33, a cross rail 34 that is horizontally suspended between the main shaft boxes 33, and a main shaft box 35 that is supported by the cross rails 34 and can move up and down and left and right.
It consists of an automatic tool changer 36 and the like provided on one column 33.

The main shaft box 35 is equipped with a vertical main shaft 37, which is connected to a rotary drive machine 38 attached to the head of the main shaft box body.
A tool (not shown) is attached to the lower part of the vertical main shaft 37.

The machine tool 30 has such a structure, and the table 32 is moved by the linear movement of the table 32 and the vertical and horizontal feed of the tool attached to the vertical spindle 37.
It is designed to process a workpiece (not shown) placed thereon.

Conventionally, in order to widen the machining range, an attachment 39 is attached to the spindle box 35 and a tool is attached to the horizontal spindle 40 provided on the attachment 39 for machining. is being carried out.

Attachment 39 is often attached to main shaft box 3.
The vertical main shaft 37 of the main shaft box 35 and the horizontal main shaft 40 of the attachment 39 are connected to each other so that their rotational force is transmitted.

The main shaft box 35 and the attachment 39 are connected to each other by engaging and removing a clamp mechanism 41 provided on the main shaft box body and a clamp flange 42 provided on the attachment main body.

Therefore, in the vicinity of the machine tool 30, an automatic attachment exchange device disclosed in, for example, Japanese Utility Model Application Publication No. 55-156833 is conventionally provided, and the attachment 39 is stored at a considerable distance from the machine tool 30 when not in use. was.

However, such a structure requires large-scale equipment for storing the attachments and requires a large floor space, which is very inconvenient.

However, it is necessary to protect the storage area of attachments and the automatic attachment exchange device from chips and dust, but since the area to be protected is large, the equipment becomes large and complicated, which leads to high costs.

Furthermore, since the distance from the spindle box to the storage location for the attachments is long, this movement takes time, making preparation work time-consuming and hindering the actual machining work.

This invention was devised in order to solve the problems mentioned above.The purpose of this invention was to focus on the fact that the column of a machine tool is hollow, and to store the attachment inside the column. By using the column as part of the dust-proof wall, the dust-proof equipment is simplified, and the distance from the attachment storage position to the mounting position is shortened, making it faster. To provide an attachment storage device for a machine tool which enables this kind of preparatory work to be carried out and also allows storage of a dustproof cover attached to a spindle box instead of an attachment.

The basic structure of the present invention is a bed that is long in the front and back direction, a table placed on top of the bed that moves back and forth in the back and forth direction, and a hollow interior that stands upright on both sides of the bed. a column, a cross rail suspended horizontally between both columns, and a main shaft box that is supported by the cross rail and can move up and down and left and right with respect to the column, and to which an attachment or a dustproof cover can be detachably attached. In a machine tool consisting of a machine tool, an opening is bored in the front wall of the column, and a cradle capable of supporting an attachment detached from the spindle box and moving it from a storage position inside the column to a mounting position outside the column. The present invention is characterized in that a dustproof cover that can open and close the opening is provided, and a receiver is provided on the pedestal to support the dustproof cover detached from the spindle box.

In other words, the interior of the column is designated as a storage area for attachments, and an opening is made in the front wall of the column to serve as an entrance and exit for attachments. If the attachment is placed in the attachment position outside the column, it can be attached to the spindle box, and if the attachment is moved to the storage position inside the column, the dust cover will close the opening that is the entrance and exit. Then, the attachment is surrounded by each wall of the column and a dustproof cover, and a receptacle for the dustproof cover is provided on the pedestal to secure a storage space, and this can also be attached to the main shaft box. It was made in a similar manner.

The attachment storage position 1 according to the present invention is applied to the machine tool 30 shown in FIG.
5, an attachment 39, a dustproof cover 43, etc.

In this example, the cross rail 34 is connected to the column 3.
3, and the cross rail 34 like this
The main spindle box 35 moves vertically and horizontally relative to the column 33, but the cross rail 34 moves up and down with respect to the column 33, and the main spindle box 35 moves left and right along the cross rail 34. There is no problem even if it is machine 30. In short, the main shaft box 35
is supported by the cross rail 34 and the column 3
It suffices if the configuration is such that it can move up and down and left and right with respect to 3.

The main parts of the attachment storage device 1 according to the present invention include an opening 2, an attachment moving mechanism 3, a dustproof cover 4, and a receiver 5 for the dustproof cover.

The opening 2 is formed in the front wall 44 of one column 33 of the machine tool 30, and is sized to allow the attachment 39 to pass therethrough.

The attachment moving device 3 includes a pedestal 6 on which an attachment 39 is placed and holds it in an upright state, a guide body 7 that guides and supports the pedestal 6 so as to be slidable in the front-rear direction, and a part between them. It consists of a moving cylinder 8 which is interposed in and moves the pedestal 6 from a storage position inside the column 33 to a mounting position outside the column 33.

Holding plates 9 for holding the attachment 39 upright are provided on both left and right sides of the upper rear half of the pedestal 6, and the attachment 3 is mounted on the rear upper part.
A positioning protrusion 10 that can be fitted into a positioning hole 45 recessed in the lower part of the holder 9 is provided. In addition, in this example, in order to provide the receiver 5, the receiver 6 has the opening 2 even in the storage position.
It's coming out from the outside.

The guide body 7 extends horizontally in and out of the column 33 with an opening 2 bored in the column 33 as the boundary, and a support plate 11 attached to the lower half of the column 33 is connected to the front wall 4 of the column 33.
4 with bolts etc. A moving cylinder 8 is interposed between brackets 12 and 13 which are vertically disposed at the rear lower part of the guide body 7 and the front lower part of the pedestal 6, respectively.

The guide body 7 and the moving cylinder 8 are not provided as in this example, but can also be mounted by making good use of the column 33.

The dustproof cover 4 is for closing the opening 2 when the attachment 39 is in the storage position within the column 33.

In this embodiment, not only the pedestal 6 and guide body 7 of the attachment moving mechanism 3 protruding outside the column 33 but also the holder 5 can be covered. It has a box shape consisting of a wall 15, a lower front vertical wall 16, left and right side walls 17, 18, and a portion of each of the upper wall 15 and the lower front vertical wall 16 is fixed to the pedestal 6.

If the dustproof cover 4 is fixedly placed on the pedestal 6 as in this example, the opening 2 can be opened and closed as the pedestal 6 moves, and the opening/closing drive mechanism dedicated to the dustproof cover 4 can be omitted.

The receiver 5 is for mounting and supporting the dustproof cover 43, and is provided on the receiver 6 of the attachment moving mechanism 3.

In the case of this embodiment, it is provided at the front part of the pedestal 6 and arranged so as not to interfere with the attachment 39. Therefore, inside column 33, attachment 3
Since only 9 can be accommodated, the holder 6 is extended forward and the holder 5 is located outside the so-called column.

In addition, the receiver 5 is a lifting cylinder 1 provided on the receiver 6.
9, the upper wall 15 of the dustproof cover 4 is configured to be able to be raised and lowered from the storage position to the mounting position.
An entrance/exit 20 is drilled therein, and a lid 21 for opening and closing the lid is pivotally attached to the dust-proof cover 4 so as to be able to rise and fall freely. I try to do it.

Note that the receiver 5 is provided with a positioning projection 23.

The dustproof cover 43 is attached to the spindle box 35 instead of the attachment 39, and includes a clamp flange 46 that is held by a clamp mechanism 41 provided on the main spindle box body, and a through hole through which the vertical spindle 37 is inserted. 47 and a positioning hole 48 into which the positioning protrusion 23 of the receiver 5 can fit.

Although not shown, this dust-proof cover 43 is for dust-proofing a positioning tooth ring etc. provided at the bottom of the spindle box 35, and this positioning tooth ring is used when the attachment 39 is attached to the spindle box. The attachment 39 is also provided with a similar tooth ring that meshes with the attachment 39.

Next, the operation in such a configuration will be explained.

2 through 4 show the attachment 39 in the retracted position of the column 33.

That is, the attachment 39 is placed on the pedestal 6 and held in a vertical position by the holding plate 9, and the positioning hole 4 on the attachment 39 side is
A positioning protrusion 10 is fitted into the portion 5 and secured at a predetermined position.

At this time, the dustproof cover 4 attached to the pedestal 6 closes the opening 2 of the column 33 and the attachment 39
is surrounded by the dustproof cover 4 and the walls of the column 33. Further, since the lid body 21 is closed, the dustproof cover 43, the receiver 5, etc. are also covered by the dustproof cover 4, and no chips or the like can enter.

When attaching the attachment 39 to the spindle box 35, the moving cylinder 8 is extended to move the pedestal 6 forward relative to the guide body 7. Then, the dustproof cover 4 attached to the pedestal 6 automatically opens the opening 2, and the attachment 39 on the pedestal 6 moves from the storage position in the column 33 through the opening 2 to the position shown in FIG. It will proceed to the mounting position outside the column 33 shown.

Then, the attachment 39 can be attached by appropriately moving the spindle box 35 sideways and lowering it.
In other words, a clamp mechanism 41 provided on the spindle box body and a clamp flange 42 provided on the attachment body.
It can be installed at.

Of course, if the attachment 39 is no longer needed and needs to be stored, this can be done by reversing the procedure described above.

Next, when the attachment 39 is not attached to the spindle box 35, that is, when a tool is attached to the vertical spindle 37, a dust-proof A cover 43 is attached. This attachment is performed by a clamp mechanism 41 provided on the spindle box body and a clamp flange 46 of the dustproof cover 43 that is gripped by the clamp mechanism 41.

When attaching the dustproof cover 43 to the spindle box 35,
First, the opening/closing cylinder 22 is extended to open the lid 21, and the entrance/exit 20 is opened as shown in FIG.

Next, the main spindle box 35 is laterally moved and lowered as appropriate to the mounting position shown by the imaginary line in FIG. to rise. This allows the dustproof cover 43 to be attached to the main body of the spindle box 35. Of course, the dustproof cover 43 may be raised first, and then the spindle box 35 may be moved and attached.

When removing the dustproof cover 43 from the spindle box 35 side and storing it in the dustproof cover 4, it is sufficient to perform the procedure in the reverse order as described above.

In this embodiment, the dustproof cover 4 is fixed to the pedestal 6, but the present invention is not limited to this. For example, one side of the dustproof cover 4 may be pivotally connected to the column 33 by a vertical shaft so that it can pivot, and the cover may be opened and closed by an opening/closing cylinder or the like. In this case, the entrance/exit 20 for the dustproof cover 43, the lid 21, the opening/closing cylinder 2
2 can be omitted.

Further, in this embodiment, there is not enough space inside the column 33 to accommodate only the attachment 39, and the receiver 5 is provided at the front part where the holder 6 is extended outside the column 33. The dustproof cover 4 is box-shaped in order to open and close the opening 2, but if the column 33
If there is sufficient internal space, both the dustproof cover 43 and the attachment 39 can be housed within the column 33, and the dustproof cover 4 can be constructed in the form of a flat plate.

Furthermore, the dustproof cover 4 is made into a flat plate so that only the opening 2 can be opened and closed, and a receptor 5 is provided at the front of the pedestal 6 extending outside the column 33, that is, in front of the dustproof cover 4, A configuration in which an opening/closing cover exclusively for the body 5 is provided separately may also be used.

In addition, in this embodiment, the receiver 5 is made to be able to move up and down by the lifting cylinder 19, but the receiver 5 is raised and fixed to the pedestal 6, and the movement of the spindle box 35 is The dust-proof cover 43 may be attached to the spindle box 35 by means of a chisel. In this case, it will be similar to the attachment 39, and the lifting cylinder 19 can be omitted.

Further, in this embodiment, the dustproof cover 43 is arranged at the front and the attachment 39 is arranged at the rear, but the arrangement may be reversed.

As described above, according to the present invention, since the hollow column of the machine tool is used as a storage place for the attachment, the space can be used effectively, and the floor space does not become large and does not get in the way.

Each wall of the column can be used as a dust barrier, so
Dust control equipment can be extremely simplified.

The attachment can be attached to the spindle box simply by moving it from the storage position inside the column to the attachment position outside the column, so the distance it must be moved is extremely short, and the moving device can be simplified. However, because the moving distance is short, so-called preparation work can be done quickly, and the original work will not be hindered.

When a dustproof cover is attached to the pedestal, the opening of the column can be opened and closed as the pedestal moves, and a dedicated drive device can be omitted.

The pedestal is provided with a receiver that can hold the dustproof cover so as not to interfere with the attachment, so the dustproof cover can be stored when not in use, and can also be attached to the spindle box.

Furthermore, if the dustproof cover is box-shaped and covers the dustproof cover, chips etc. will not adhere to it.

The structure is extremely simple, and by making it into a unit, it can be easily applied to existing machine tools, etc., and has various effects.
