[0071] The processing machine 10 may also include a support body 91 (see Figure 2 The support body 91 is connected to the main body 41 to support the main body 41. The support body 91 is substantially the same as the support body 87.
[0072] The following describes how to use the processing machine 10. First, the robot 11 positions the X linear motion unit 20 at a predetermined processing position (not shown). The support 87 may also be connected to the X linear motion unit 20. During processing, the robot 11 holds the X linear motion unit 20 at the processing position.
[0073] During hole drilling, the following operations are performed. The X-drive unit 22 positions the X-slide 31 at the specified drilling position (not shown). At this point, the support 91 may be connected to the main body 41 to support it. The spindle motor 65 then rotates the spindle 59. While holding the X-slide 31 at the drilling position, the Z-motor 53 advances the ram 47 and retracts it after reaching the specified depth.
[0074] During milling, the following operations are performed. The X-drive unit 22 positions the X-slide 31 at the specified machining start position (not shown). The spindle motor 65 then rotates the spindle 59. The Z-motor 53 then extends the ram 47 to a specified height. The X-drive unit 22 then conveys the X-slide 31 in the X direction, allowing the tool 1 to mill the workpiece. When the X-slide 31 reaches the specified machining end position, the Z-motor 53 retracts the ram 47.
[0075] In the processing machine of Patent Document 2, the processing point is far away from the tip of the robot arm, and sufficient rigidity cannot be ensured.
[0076] In contrast, according to the processing machine 10 of this embodiment, the center of gravity of the end effector 15 can be brought closer to the connection surface 11a of the robot 11. Furthermore, the tip of the spindle 59 can be brought closer to the connection surface 11a. During machining, cutting resistance or cutting vibration acts on the spindle 59. By bringing the tip of the spindle 59 closer to the connection surface 11a of the robot 11, the load on the robot 11 can be reduced. Consequently, the overall rigidity of the processing machine 10 is improved.
[0077] When the processing machine 10 includes a support 87, the X linear motion unit 20 is supported by the support 87. In this case, the support 87 bears all or part of the cutting resistance or cutting vibration acting on the spindle 59. This reduces the load on the robot 11 during machining, thereby improving the overall rigidity of the processing machine 10.
[0078] The Z drive cylinder 83 pushes the Z slider 45 forward. The Z motor 53 bears the cutting resistance during drilling. The Z drive cylinder 83 can reduce the cutting resistance acting on the Z motor 53. Furthermore, if the Z drive cylinder 83 is a compressible fluid drive cylinder, the Z drive cylinder 83 absorbs cutting vibrations. This reduces the output torque of the Z motor 53 and allows for miniaturization of the Z motor 53.
[0079] The X-drive cylinder 36 pushes the X-slide 31 left and right. The X-motor 27 bears the cutting resistance during milling. The X-drive cylinder 36 can reduce the cutting resistance acting on the X-motor 27. Furthermore, when the X-drive cylinder 36 is a compressible fluid-driven cylinder, it absorbs cutting vibrations. This reduces the output torque of the X-motor 27 and allows for a more compact X-motor 27.
[0080] When the Z drive cylinder 83 or the X drive cylinder 36 is provided, the mass or inertia of the end effector 15 can be reduced by miniaturizing the Z motor 53 or the X motor 27 .
[0081] (Implementation Method 2)
[0082] like Figure 4 and Figure 5 As shown, the processing machine 100 of this embodiment includes a robot 11 and an end effector 115. The end effector 115 includes an X linear motion unit 20, a Y linear motion unit 120, and a processing unit 40. Figure 5 It is a plane passing through the centers of the X feed screw 23 and the Y feed screw 123 and is a cross-sectional view of the X linear motion unit 20 and the Y linear motion unit 120 .
[0083] The Y linear motion unit 120 includes a Y frame 121, a Y guide 129, a Y slider 131, a Y drive unit 122, a fixed cover 133, and a sliding cover 134. The Y linear motion unit 120 extends along the Y direction. The Y frame 121 is connected to the X slider 31. The Y frame 121 and the X slider 31 may also be integrally formed. The Y frame 121 may also have a rib 121a. The rib 121a extends along the XY direction, connecting the Y frame 121 and the X slider 31.
[0084] The Y guide 129 extends in the Y direction and is disposed on the Y frame 121. The Y slider 131 is disposed on the Y guide 129 and reciprocates in the Y direction.
[0085] The Y drive device 122 includes a Y feed screw 123, a bearing 124, a pulley 125, a Y motor (not shown) and an endless belt 126. The Y drive device 122 may also have a Y drive cylinder (not shown). The Y feed screw 123 is supported on the Y frame 121 via the bearing 124. The Y feed screw 123 is connected to the Y slider 131. The pulley 125 is connected to the Y motor via the endless belt 126. The Y motor drives the Y slider 131 in the Y direction. The Y drive cylinder is, for example, an air cylinder. The Y drive cylinder may also be a double-acting cylinder. When the Y slider 131 moves in the -Y direction, the Y drive cylinder applies force to the Y slider 131 in the -Y direction. When the Y slider 131 moves in the +Y direction, the Y drive cylinder applies force to the Y slider 131 in the +Y direction.
[0086] Otherwise, the Y linear motion unit 120 is substantially the same as the X linear motion unit 20. The Y stroke 4 of the Y linear motion unit 120 is preferably smaller than the X stroke 3 of the X linear motion unit 20. The Y stroke 4 is preferably 50% or less of the X stroke 3, more preferably 30% or less.
[0087] Furthermore, the sliding cover 134 and the cover of the X linear motion unit 20 can be freely designed to avoid interference. For example, the sliding cover 134 can be inserted between the sliding cover 34 and the X slider 31. The sliding cover 34 can also have a curved portion 34a.
[0088] In addition, the Y motor (not shown) may be directly connected to the Y feed screw 123. The Y motor (not shown) may be connected to the Y feed screw 123 via a coupling (not shown).
[0089] The processing unit 40 is connected to the Y slider 131. The main body 41 and the Y slider 131 may be formed integrally.
[0090] According to the processing machine 100 of this embodiment, the spindle 59 can be moved in the XYZ directions while maintaining the position of the arm 11b of the robot 11. Therefore, milling of a tool with a width greater than the diameter of the tool 1 or milling of an L-shaped surface drawn on the XY plane can be stably performed.
[0091] Since the Y stroke 4 is smaller than the X stroke 3, the processing point and the connection surface 11a can be brought closer together, thereby improving the rigidity of the entire processing machine 10.
[0092] (Implementation 3)
[0093] like Figure 6 As shown, the processing machine 200 of this embodiment includes a robot 11 and an end effector 215.

The W motor may also be directly connected to the W feed screw 223. The W motor may also be connected to the W feed screw 223 via a coupling (not shown). The W motor drives the W slider 231 in the W direction. The W drive cylinder is arranged on the W frame 221 and applies force to the W slider 231 in the -W direction. The W drive cylinder is, for example, an air cylinder. For example, the W drive cylinder is a single-acting cylinder.

[0102] Furthermore, the X linear motion unit 20 may be omitted. In this case, the W frame 221 is directly connected to the connection surface 11a.
[0103] exist Figure 3 The processing machine 10 of the embodiment 1 shown or Figure 5 In the machining center 100 of the second embodiment shown, the machining unit 40 as a whole cannot be moved in the -Z direction relative to the connection surface 11a of the robot 11. Furthermore, the front end surface of the main body 41 of the machining unit 40 is close to the front end surface of the X linear motion unit 20 or the Y linear motion unit 120. Therefore, the amount of protrusion of the ram 47 relative to the X linear motion unit 20 or the Y linear motion unit 120 is approximately equal to the Z stroke 6 of the machining unit 40.
[0104] Furthermore, the front surface of the X linear motion unit 20 or the Y linear motion unit 120 becomes larger around the base end portion of the ram 47 .
[0105] In contrast, Figure 6 As shown, according to the processing machine 200 of this embodiment, the W linear motion unit 220 can cause the W slide block 231 and the processing unit 40 to protrude toward the top end direction (-W direction) of the main spindle 59. Furthermore, the processing unit 40 can extend the ram 47. Therefore, the ram 47 can protrude relative to the X linear motion unit 20 by the W stroke 5 and the Z stroke 6 of the W linear motion unit 220 (see Figure 3 ). The XY cross-section of the machining unit 40 is smaller than the XY cross-section of the entire end effector 215. For example, the XY cross-section of the machining unit 40 is less than half the XY cross-section of the entire end effector 215. Furthermore, the cross-section of the ram 47 is significantly smaller than the XY cross-section of the machining unit 40. For example, the cross-section of the ram 47 is 5% to 10% of the XY cross-section of the machining unit 40. Therefore, according to the processing machine 200, the tool 1 can be inserted into a narrow portion of the workpiece, thereby enabling processing.
