Japanese Patent Application Laid-Open No. 2002-113639 International Publication No. 2013/035693

In the art, it is desirable to reduce the footprint of the entire line. Then, an object of this invention is to provide the machine tool which can convey a workpiece | work in arbitrary directions using only the feed mechanism for processing, without providing a conveyance apparatus between machine tools.

One aspect of the present disclosure is a machine tool that moves a tool and a work relative to each other to process a work, and includes a bed, and a table disposed on the bed and supporting the work, the table comprising A first rotary base disposed on the bed and rotating about the first rotary axis, and a second rotary base provided on the first rotary base, the second rotary base being parallel to the first rotary axis and It is a machine tool which has a 2nd rotation stand rotated centering around the 2nd rotation axis which revolves around the 1st rotation axis.

In a machine tool according to an aspect of the present disclosure, the table includes a second rotation table that can revolve around a first rotation axis. Therefore, the table can move the work in any direction by revolving around the first rotation axis. The second rotation table is rotatable about the second rotation axis. Therefore, the table can control the posture of the workpiece by rotation about the second rotation axis. Therefore, the table can control the posture of the work in a posture suitable for conveyance between the machine tools. With the above-described configuration, in the machine tool according to one aspect of the present disclosure, it is possible to transport the work in an arbitrary direction only by the table.

The machine tool comprises a spindle for gripping the tool, a first linear feed mechanism for moving the spindle in the vertical direction, and a second linear feed mechanism for adjusting the horizontal distance between the spindle and the first rotation axis The first rotation axis may extend along the vertical direction. In this case, since the first rotation axis extends along the vertical direction, the work revolves in the horizontal plane. Also, the horizontal distance between the main shaft and the first rotational axis is adjusted by the second linear feed mechanism. In this case, the work in the horizontal direction perpendicular to the direction of the second linear feed mechanism by the revolution around the first rotation axis, the rotation around the second rotation axis, and the linear feed between the main spindle and the first rotary axis. Linear feed is substantially possible. Therefore, linear motion feeding in three axial directions is substantially possible. According to this configuration, the machine tool according to an aspect of the present disclosure can reduce the telescopic cover of one axis as compared to a machine tool having a linear movement feed mechanism in the three-axis direction. Therefore, the restriction of accessibility to the surroundings due to the telescopic cover can be reduced, and the accessibility to the surroundings can be improved. In addition, since the telescopic cover that is relatively easy to break can be reduced, the maintenance burden can be reduced.

The above-described configuration capable of three-axis linear motion feeding can be implemented by various aspects. For example, a machine tool is a column disposed on a bed so as to face the table, and a spindle head vertically moving on the column, which rotatably supports a horizontally configured spindle. The head may further include a slider moving on the bed in a direction in which the column and the table face each other and rotatably supporting the first turntable. In this case, the main shaft is horizontal, and the second linear feed mechanism is provided on the table side. It should be noted that the main spindle may be vertical, and the second linear feed mechanism may be provided on the column side.

The machine tool may further include a column arranged to face the table on the bed, and a splash guard that horizontally surrounds the table and the column, and the splash guard is in the direction in which the table and the column face each other. There may be a pair of openable and closable openings arranged to face each other across the table in the direction perpendicular to (ie, the left and right direction). In this case, for example, the work can be transported in the left-right direction through the first opening.

The splash guard may have an openable and closable opening disposed to face the column with the table in between in the direction in which the table and the column face each other (ie, in the front-rear direction). In this case, for example, the work can be transported in the front-rear direction through the second opening. Also, for example, a worker can perform various operations through the second opening.

The table may further include a table face plate provided on the second rotary table and rotating about a third rotation axis perpendicular to the second rotation axis. In this case, in addition to the rotation about the second rotation axis, the table can further control the posture of the workpiece by the rotation about the third rotation axis. Therefore, the workpiece can be transported in various postures by rotation with two degrees of freedom.

According to one aspect of the present disclosure, it is possible to provide a machine tool capable of transporting a workpiece in any direction using only a feed mechanism for processing.

Hereinafter, a machine tool according to an embodiment will be described with reference to the attached drawings. The same or corresponding elements are denoted by the same reference numerals, and redundant description will be omitted. The scale of the figures may have been changed to facilitate understanding.

1A is a plan view showing a machine tool according to an embodiment, FIG. 1B is a front view showing the machine tool according to FIG. 1A, and FIG. 1C is a right side view showing the machine tool according to FIG. Referring to FIGS. 1A to 1C, machine tool 100 is, for example, a horizontal machining center. The machine tool 100 may be another machine tool having a table, such as a vertical machining center. The machine tool 100 is configured to move the tool T and the work W (see FIG. 2A) relative to each other to process the work W. Referring to FIGS. 1A to 1C, machine tool 100 includes a bed (also referred to as a base) 10, a column 20, and a table 30.

The bed 10 may be fixed to, for example, a floor of a factory. A column 20 is provided on the bed 10 along the back 11 of the bed 10. At the front of the column 20, a spindle head (first linear feed mechanism) 21 movable in the vertical direction is provided. A spindle 22 is provided on the front of the spindle head 21. In the present embodiment, the main shaft 22 is configured to be horizontal, and the main spindle head 21 supports the main shaft 22 rotatably around a horizontal rotation axis Os. The spindle 22 holds the tool T.

Regarding the direction in the machine tool 100 according to the present embodiment, the rotation axis Os of the main shaft 22 is along the horizontal direction, and the direction parallel to the rotation axis Os is defined as the Z-axis direction (also referred to as the front-rear direction). . The direction in which the main shaft 22 protrudes along the Z-axis direction is the front, and the opposite direction is the rear. A horizontal direction perpendicular to the Z-axis direction is defined as an X-axis direction (also referred to as a left-right direction), and a vertical direction is defined as a Y-axis direction (also referred to as an up-down direction).

The spindle head 21 can, for example, be driven in the Y-axis direction by means of a feed device having a ball screw B1 connected to a motor M1 and be guided by a guide L1. The ball screw B1 and the guide L1 can be covered by, for example, a telescopic cover (not shown). The ball screw B1 can have, for example, a screw shaft rotatably supported by the column 20 and extending in the Y-axis direction, and a nut fixed to the spindle head 21. By rotating the screw shaft by the motor M1, the nut is moved in the Y-axis direction, and thus the spindle head 21 is moved in the Y-axis direction. The feed in the Y-axis direction is controlled by the NC device.

The table 30 is disposed on the bed 10 so as to face the column 20. The table 30 supports the work W. The table 30 has a slider (second linear feed mechanism) 31, a first rotary table 32, a second rotary table 33, and a table surface plate 34.

The slider 31 moves on the bed 10 along the direction (Z-axis direction) in which the column 20 and the table 30 face each other. The slider 31 can be driven in the Z-axis direction by, for example, a feeding device having a ball screw B2 connected to the motor M2, and can be guided by the guide L2. The ball screw B2 and the guide L2 can be covered by, for example, a telescopic cover (not shown). The ball screw B2 can have, for example, a screw shaft rotatably supported on the bed and extending in the Z-axis direction, and a nut fixed to the slider 31. By rotating the screw shaft by the motor M2, the nut is moved in the Z-axis direction, and thus the slider 31 is moved in the Z-axis direction. The feed in the Z-axis direction is controlled by the NC device. According to the above configuration, the slider 31 can adjust the distance in the X-axis direction between the main shaft 22 and the first rotation axis Ob1 (described later) of the first rotary table 32.

The slider 31 rotatably supports the first rotary table 32. The slider 31 has, for example, a cross roller bearing, and the first rotary base 32 is rotated about the first rotation axis Ob1 by, for example, a motor or a hydraulic device. The first rotation axis Ob1 extends in the vertical direction in the present embodiment. In other embodiments, the first rotation axis Ob1 may be inclined or may extend along the horizontal direction. The rotation around the first rotation axis Ob1 is controlled by the NC device.

The first rotation table 32 extends in the horizontal direction from the first rotation axis Ob1. The first rotary base 32 rotatably supports the second rotary base 33 at a position separated in the horizontal direction from the first rotation axis Ob1. The first rotary base 32 has, for example, a cross roller bearing, and rotates the second rotary base 33 about the second rotation axis Ob2 by, for example, a motor or a hydraulic device. The second rotation axis Ob2 is parallel to the first rotation axis Ob1, that is, in the present embodiment, extends in the vertical direction, and is separated from the first rotation axis Ob1. The second rotation axis Ob2 revolves around the first rotation axis Ob1. The rotation around the second rotation axis Ob2 is controlled by the NC device.

The second rotary base 33 protrudes upward from the first rotary base 32. The second rotation table 33 rotatably supports the table surface plate 34. The second rotary table 33 has, for example, a cross roller bearing, and rotates the table surface plate 34 about the third rotation axis Oa by, for example, a motor or a hydraulic device. The third rotation axis Oa extends perpendicular to the second rotation axis Ob2, that is, in the horizontal direction in the present embodiment. The rotation around the third rotation axis Oa is controlled by the NC device.

The table face plate 34 is provided vertically and faces in the horizontal direction. The table surface plate 34 can be provided with gripping means (for example, a chuck mechanism) H (see, for example, FIG. 3A) for gripping the work W.

2A is a plan view showing the feeding operation in the X-axis direction during processing of the table shown in FIGS. 1A to 1C, FIG. 2B is a plan view showing the feeding operation following FIG. 3A, and FIG. FIGS. 4A and 4B are plan views showing the feeding operation following FIG. 3B. With reference to FIG. 2A, in the machine tool 100 described above, the revolution of the first rotation axis Ob1, the rotation around the second rotation axis Ob2, and the linear movement in the Z-axis direction substantially move the workpiece W Linear movement (translational movement) in the X-axis direction is possible. Specifically, referring to FIGS. 2A to 2C, rotating the first rotary base 32 clockwise around the first rotation axis Ob1 and moving the slider 31 forward along the Z-axis direction. Thus, the workpiece W can be moved to the right along the X-axis direction. Position P0 in FIGS. 2B and 2C indicates the initial position of the front surface of the slider 31 in FIG. 2A, and it can be seen that the slider 31 is moved forward along the Z-axis direction. At this time, by rotating the second rotary table 33 counterclockwise around the second rotation axis Ob2, the workpiece W is moved rightward along the X-axis direction while maintaining the posture of the workpiece W around the Y-axis. Can be translated to When the tool T contacts the workpiece W, the workpiece W is processed.

FIG. 3A is a plan view showing an example of two machine tools for transporting a work. As shown in FIG. 3A, by using a plurality of the machine tools 100 described above, the workpiece W can be transported without providing a transport device. The workpiece W can be transported in various postures in accordance with various conditions such as the shape of the workpiece W, the processing position, and / or the type of processing. For example, in FIG. 3A, a long workpiece W is transported from the machine tool 100 on the left to the machine tool 100 on the right. In the machine tool 100 on the left side, the end face of the workpiece W needs to be gripped, and in the machine tool 100 on the right side, the side surface of the workpiece W needs to be gripped. Therefore, the third rotation axis Oa of the left table surface plate 34 and the third rotation axis Oa of the right table surface plate 34 need to form 90 ° with each other. In FIG. 3A, the sliders 31, the first rotary base 32, the second rotary base 33, and the table surface plate 34 of each of the left and right machine tools 100 control so that the longitudinal axis of the workpiece W becomes parallel to the X axis direction. It is done.

FIG. 3B is a plan view showing another example of two machine tools for transporting a work. In the machine tool 200 of FIG. 3B, a second linear motion feed mechanism in the Z-axis direction is provided on the column 20 side instead of the table 30 side. The column 20 is moved in the Z-axis direction on the bed 10 by a feeding device having a ball screw B3 connected to the motor M3, and is guided by the guide L3. The first rotary base 32 is rotatably supported by a fixed base 35 fixed to the bed 10 in place of the slider 31. The fixing base 35 can rotatably support the first rotation base 32 by a rotation mechanism similar to the above-described rotation mechanism of the slider 31. Other components of machine tool 200 can be configured similarly to corresponding components of machine tool 100. In FIG. 3B, as in FIG. 3A, the left end of the machine tool 200 needs to hold the end face of the long work W, and the right machine tool 200 needs to hold the side of the work W. The third rotation axis Oa of the left table surface plate 34 and the third rotation axis Oa of the right table surface plate 34 need to form 90 ° with each other. In FIG. 3B, since there is no linear motion feed mechanism in the Z-axis direction on the table 30 side, for example, each of the left and right machine tools 200 so that the longitudinal direction of the long work W is inclined with respect to the X-axis direction. The first rotary table 32, the second rotary table 33, and the table face plate 34 are controlled. As described above, even when there is no linear motion feed mechanism in the Z-axis direction on the table 30 side, the work W can be transported by using a plurality of machine tools 200.

FIG. 4A to FIG. 4C are plan views showing still another example of two machine tools for conveying a work. In FIG. 4A, the workpiece W is conveyed from the machine tool 100 on the left to the machine tool 100 on the right. In the machine tool 100 on the left side, one of the opposing end faces of the workpiece W needs to be grasped, and in the machine tool 100 on the right side, the other side of the opposing end faces needs to be grasped. Therefore, the left and right table face plates 34 need to face each other. In FIG. 4A, the slider 31, the first rotation base 32, the second rotation base 33, and the table surface plate 34 are controlled such that the third rotation axis Oa is parallel to the X-axis direction.

In FIG. 4B, a workpiece W shorter than the workpiece W in FIG. 4A is being transported. For this reason, in FIG. 4B, the slider 31, the first rotation base 32, the second rotation base 33, and the table surface plate are arranged such that the distance between the left and right table surface plates 34 is smaller than the corresponding distance shown in FIG. 4A. 34 are controlled.

In FIG. 4C, a longer workpiece W is transported as compared to the workpiece W of FIG. 4A. For example, in the case where it is difficult to make the third rotation axis Oa parallel to the X-axis direction (for example, when the work W or the table 30 interferes with peripheral devices), the third rotation axis Oa extends in the X-axis direction The slider 31, the first rotary base 32, the second rotary base 33, and the table face plate 34 can be controlled to be inclined with respect to the other.

FIG. 5 is a plan view showing a machine tool provided with a splash guard. The machine tool 100 may further include a splash guard 50 for preventing chip scattering. The splash guard 50 encloses at least the table 30 and the column 20 at least in the horizontal direction, specifically from the front, rear, left and right. The splash guard 50 has a pair of first openings 51 arranged to face each other across the table 30 in a direction (that is, the X-axis direction) perpendicular to the direction in which the table 30 and the column 20 face each other. doing. Each first opening 51 is provided with a shutter S that can slide. Therefore, each first opening 51 can be opened and closed. It should be noted that the first opening 51 may be provided with a pivotable door instead of the shutter S.

Further, the splash guard 50 further includes a second opening 52 disposed so as to face the column 20 across the table 30 in the direction in which the table 30 and the column 20 face each other (that is, the Z-axis direction). ing. The second opening 52 is provided with a pivotable door D. Therefore, the second opening 52 can be opened and closed. It should be noted that the second opening 52 may be provided with a slidable shutter instead of the door D.

FIG. 6 is a plan view showing a line 300 according to the embodiment. Referring to FIG. 6, line 300 includes four machine tools 100A to 100D having substantially the same configuration as machine tool 100 shown in FIG. The machine tools 100A to 100D are arranged in the same direction, and are arranged linearly along the left-right direction. The first opening 51 and the shutter S between adjacent machine tools can be shared by these machine tools. The workpiece W is transported from the machine tool 100A to the machine tool 100D through the first opening 51 by the table 30 of the machine tools 100A to 100D. In the machine tools 100A to 100D, the workpiece W is subjected to different processing. For example, in the third machine tool 100C, the workpiece W receives necessary processing (for example, assembly of other parts, inspection of the workpiece W, etc.) from the operator or other devices through the second opening 52. be able to.

FIG. 7A is a plan view showing the operation of the line according to another embodiment, and FIG. 7B is a plan view showing the operation of the line following FIG. 7A. Referring to FIG. 7A, line 400 includes four machine tools 100E to 100H having substantially the same configuration as machine tool 100 shown in FIG. The three machine tools 100E to 100G are arranged in the same direction, and are arranged linearly along the left-right direction. The machine tool 100H shares the second opening 52 with the machine tool 100F (or the spindle 22 of the machine tool 100H and the spindle 22 of the machine tool F face each other), and reverses the machine tools 100E to 100G. It is arranged in the direction. The second opening 52 between the machine tool 100F and the machine tool 100H is provided with a shutter S, not a door. Further, the machine tool E is not provided with the second opening 52.

In the line 400, the workpiece W1 and the workpiece W2 are combined into a workpiece W3. Specifically, after the workpiece W1 is introduced into the machine tool 100E through the first opening 51 and subjected to machining, the workpiece W1 is conveyed to the machine tool 100F through the first opening 51 and further subjected to machining. Further, the workpiece W2 is introduced into the machine tool 100H through the first opening 51 and subjected to processing.

Referring to FIG. 7B, next, work W1 held by machine tool 100F and work W2 held by machine tool 100H are combined with work W3 through second opening 52. The workpiece W3 is transported from the machine tool F to the machine tool G through the first opening 51, and is further processed. Returning to FIG. 7A, the workpiece W3 processed by the machine tool 100G is transported to the outside of the line 400 or to a subsequent process through the first opening 51.

In the

machine tool

100, 200 of the present disclosure as described above, the table 30 has the second rotation table 33 capable of revolving around the first rotation axis Ob1. Therefore, the table 30 can move the work W in any direction by revolving around the first rotation axis Ob1. The second rotation base 33 is rotatable about the second rotation axis Ob2. Therefore, the table 30 can control the posture of the workpiece W by rotation around the second rotation axis Ob2. Therefore, the table 30 can control the posture of the workpiece W in a posture suitable for conveyance between the

machine tools

100 and 200. With the above configuration, in the

machine tool

100, 200, it is possible to transport the workpiece W in an arbitrary direction only by the table 30.

The

machine tools

100 and 200 also include a main spindle 22 for gripping the tool T, a first linear feed mechanism for moving the main spindle 22 in the vertical direction, and a horizontal distance between the main spindle 22 and the first rotation axis Ob1. And a second linear movement feed mechanism for adjusting the first rotation axis Ob1 extending in the vertical direction. According to this configuration, linear motion feeding of the workpiece W in the X-axis direction is substantially possible by the revolution around the first rotation axis Ob1, the rotation around the second rotation axis Ob2, and the linear motion feeding in the Z axis direction. It is. Therefore, linear motion feeding in three axial directions substantially in the X-axis direction, the Y-axis direction, and the Z-axis direction is possible. According to this configuration, the revolution speed V of the work W can be calculated by V = rω ² (where r is the distance between the work W and the first rotation axis Ob 1, ω is the angular velocity). Accordingly, only by increasing the distance r between the workpiece W and the first rotation axis Ob1, the substantial Z of the workpiece W can be obtained without changing the angular velocity ω of the drive source for rotating the first rotary table 32. The speed of linear movement in the axial direction can be increased. Further, according to the above configuration, the

machine tools

100 and 200 can reduce the telescopic cover of one axis as compared with the machine tool having the linear movement feed mechanism in the three axis directions. Therefore, the restriction of accessibility to the surroundings due to the telescopic cover can be reduced, and the accessibility to the surroundings can be improved. In addition, since the telescopic cover that is relatively easy to break can be reduced, the maintenance burden can be reduced.

The above-described configuration capable of three-axis linear motion feeding can be implemented by various aspects. For example, the machine tool 100 is a column 20 disposed on the bed 10 so as to face the table 30, and a spindle head 21 vertically moving on the column 20, and rotates a spindle 22 configured horizontally. And a slider 31 moving on the bed 10 along the direction in which the column 20 and the table 30 face each other, the slider 31 rotatably supporting the first rotary table 32. And. Therefore, in the machine tool 100, the main shaft 22 is horizontal, and the second linear feed mechanism is provided on the table 30 side. The main spindle may be vertical. Further, like the machine tool 200, the second linear movement feed mechanism may be provided on the column 20 side.

The machine tool 100 further includes a splash guard 50 that horizontally surrounds the table 30 and the column 20, and the splash guard 50 is in a direction perpendicular to the direction in which the table 30 and the column 20 face each other (ie, In the left and right direction, the pair of openable and closable first openings 51 arranged to face each other across the table 30 is provided. Therefore, the workpiece W can be transported in the left-right direction through the first opening 51.

Further, in the machine tool 100, the splash guard 50 is disposed so as to face the column 20 across the table 30 in the direction in which the table 30 and the column 20 face each other (that is, the front and back direction). 2 has an opening 52; Therefore, the workpiece W can be transported in the front-rear direction through the second opening 52. In addition, various operations can be performed through the second opening 52.

Further, in the

machine tools

100 and 200, the table 30 is the table face plate 34 provided on the second rotary table 33, and rotates about the third rotation axis Oa perpendicular to the second rotation axis Ob2. The table surface plate 34 is further included. Therefore, in addition to the rotation about the second rotation axis Ob2, the table 30 can further control the posture of the work W by the rotation about the third rotation axis Oa. Therefore, the workpiece W can be transported in various postures by rotation with two degrees of freedom.

As mentioned above, although the embodiment of the machine tool was described, the present invention is not limited to the above-mentioned embodiment. Those skilled in the art will appreciate that various modifications of the above embodiments are possible. Also, for those skilled in the art, the features included in one embodiment may be incorporated in the other embodiments or may be replaced with the features included in the other embodiments as long as no contradiction arises. Will understand.

For example, in the machine tool 100, the column 20 is fixed on the bed 10. However, in other embodiments, the column 20 may move in the X-axis direction. In this case, for example, the column 20 may be moved in the X-axis direction on the bed 10 by a feeding device having a ball screw connected to a motor, and can be guided by a guide. In this case, in addition to the linear movement in the X-axis direction achieved by the slider 31, the first rotary table 32 and the second rotary table 33, the linear movement in the X-axis direction by the column 20 is also obtained. Therefore, in this case, the feeding operation in the X-axis direction can be speeded up.

Further, in the above embodiment, the table surface plate 34 is provided vertically, and rotates around the third rotation axis Oa with respect to the second rotation table 33. However, in another embodiment, the table surface plate 34 may be provided horizontally and may be fixed to the second rotary table 33.
