[0005] Patent Document 1: Japanese Patent Application Publication No. 2012-143854 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] As disclosed in Patent Document 1 above, it is known to have machining machines equipped with a safety belt connector (locking member) for connecting a safety belt. Workers connect the safety belt, which is fitted to their body, to the safety belt connector to ensure safety when working at heights. However, depending on the location of the safety belt connector, there are possibilities that: the worker expends excessive labor and time using the safety belt, or the safety belt connector affects the maximum mechanical dimensions of the machining machine.

[0008] Therefore, the object of the present invention is to provide a processing machine that solves the above-mentioned problems, has good operability when the operator uses a safety belt, and can be miniaturized.

[0009] Solution for solving the problem

[0010] The processing machine according to the present invention includes: an outer cover that constitutes the exterior of the processing machine and is used to divide and form an internal space; and a seat belt connection portion disposed in the internal space and capable of connecting a seat belt. The outer cover includes a cover portion that can be opened and closed. The seat belt connection portion is exposed to the outside of the internal space through an opening formed in the outer cover when the cover portion is in the open state.

[0011] With this configuration, when performing maintenance or other tasks, the operator can open the cover, exposing the safety belt connector to the outside of the internal space through the opening. This allows the operator to connect the safety belt to the connector, improving ease of operation when using the safety belt. Furthermore, the safety belt connector is located inside the outer casing that forms the exterior of the machine, rather than on the outermost shell. This allows for miniaturization of the machine.

[0012] Alternatively, it is preferable that the cover is positioned on top of the processing machinery.

[0013] In this type of machining machine, the safety belt connector is located inside the outer cover at the top of the machining machine, so the safety belt connector does not affect the maximum mechanical height of the machining machine.

[0014] Alternatively, it is preferable that the cover is supported by the seat belt connector.

[0015] With such a processing machine, it is easy to obtain a structure in which the seat belt connection is exposed through an opening created when the cover is in the open state.

[0016] Furthermore, preferably, the processing machine also includes a support portion that allows the cover to rotate or slide. When the cover rotates or slides, an opening is created in the outer cover.

[0017] The processing machinery configured in this way allows the cover to be opened and closed easily, thus further improving the operability for workers using safety belts.

[0018] Alternatively, preferably, the outer cover includes multiple covers that can be opened and closed independently of each other.

[0019] According to the processing machine configured in this way, at least one of the multiple covers is set to the open state in accordance with the working part in the processing machine, so that the opening can be provided in an appropriate position.

[0020] Alternatively, preferably, the seat belt connection includes a frame portion extending in one direction along the opening surface formed by the opening portion.

[0021] The machining mechanism constructed in this way can prevent the seat belt connection from obstructing the opening surface to a large extent. Therefore, it is easy for operators to perform maintenance and other tasks on the machining mechanism through the opening.

[0022] Additionally, preferably, the seat belt connection also includes a rope laid along the frame portion.

[0023] With this type of processing machinery, workers can connect the safety belt installed on their bodies to the rope.

[0024] In addition, it is preferable that the frame section is made of tubular material with a closed cross section.

[0025] The processing machinery configured in this way ensures the rigidity of the safety belt connection, thereby improving the safety of workers using safety belts.

[0026] Furthermore, preferably, the processing machinery also includes: an auxiliary processing head disposed in the processing area for spraying material powder onto the workpiece and irradiating it with a laser; a pipeline extending from the auxiliary processing head and leading out from the inside of the processing area to the outside, supplying material powder and laser to the auxiliary processing head; and a pipeline support portion disposed outside the processing area for supporting the pipeline body. The pipeline support portion is exposed to the outside of the internal space through an opening created in the outer cover when the cover is in the open state.

[0027] According to the processing machinery configured in this way, the operator can connect the safety belt installed on his body to the safety belt connector, while protecting the pipeline support through the opening created in the outer cover.

[0028] The effects of the invention

[0029] As described above, according to the present invention, a processing machine can be provided that offers good operability for workers using safety belts and can be miniaturized. Attached Figure Description

[0046] Embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, in the drawings referred to below, the same or equivalent components are labeled with the same reference numerals.

[0047] Figure 1 This is a front view showing the processing machinery in an embodiment of the present invention. Figure 1The interior of the machining machine is shown through a perspective view of the casing that forms the exterior of the machining machine. Figure 2 It is aimed at Figure 1 The machining machinery shown in the image is a three-dimensional diagram depicting the disassembly and assembly of the tool spindle and auxiliary machining head.

[0048] Reference Figure 1 and Figure 2 The machining machine 100 is an AM / SM hybrid machining machine capable of performing both AM (additive manufacturing) and SM (subtractive manufacturing) machining of workpieces. The machining machine 100 has both turning functionality using fixed tools and milling functionality using rotary tools as SM machining functions.

[0049] Machining machine 100 is an NC (Numerically Controlled) machining machine that automates various actions for machining workpieces through numerical control performed by a computer.

[0050] Furthermore, in this specification, the axis that is parallel to the left-right direction (width direction) of the machining machine 100 and extends horizontally is called the "Z-axis," the axis that is parallel to the front-back direction (depth direction) of the machining machine 100 and extends horizontally is called the "Y-axis," and the axis that extends vertically is called the "X-axis." Figure 1 The right direction in the equation is called the "+Z-axis direction", and the left direction is called the "-Z-axis direction". Figure 1 The direction in front of the paper is called the "+Y axis direction", and the direction inside is called the "-Y axis direction". Figure 1 The upward direction is called the "+X-axis direction", and the downward direction is called the "-X-axis direction". The X-axis, Y-axis, and Z-axis are three mutually orthogonal axes.

[0051] First, the overall structure of the machining machine 100 will be described. The machining machine 100 has a protective plate 181. The protective plate 181 divides the workpiece into a machining area 110.

[0052] The machining machine 100 also includes a machine base 151, a first workpiece spindle 111, a second workpiece spindle 116, and a tool holder (not shown).

[0053] The base 151 is a base component used to support the first workpiece spindle 111, the second workpiece spindle 116, and the tool holder, etc., and is installed on the ground in a factory or the like.

[0054] The first workpiece spindle 111 and the second workpiece spindle 116 are arranged opposite to each other in the Z-axis direction. The first workpiece spindle 111 and the second workpiece spindle 116 are configured to hold the workpiece. Both the first workpiece spindle 111 and the second workpiece spindle 116 are equipped with chuck mechanisms (not shown) for holding the workpiece in a detachable manner. The first workpiece spindle 111 primarily rotates the held workpiece about a rotation axis 501 parallel to the Z-axis during turning of a workpiece using a fixed tool. The second workpiece spindle 116 primarily rotates the held workpiece about a rotation axis 502 parallel to the Z-axis during turning of a workpiece using a fixed tool.

[0055] The first workpiece spindle 111 is fixed to the machine base 151. The second workpiece spindle 116 is configured to move in the Z-axis direction using various conveying mechanisms, guiding mechanisms, and servo motors. The second workpiece spindle 116 may also be fixed to the machine base 151. Alternatively, a tailstock for supporting the rotation center of the workpiece held to the first workpiece spindle 111 may be provided instead of the second workpiece spindle 116.

[0056] A tool post (not shown) is positioned within the machining area 110. The tool post is configured to hold multiple fixed tools for workpiece removal machining (turning). The tool post is supported by a machine base 151 via a saddle (not shown). The tool post is configured to move in the X and Z axes using various conveying mechanisms, guide mechanisms, and servo motors mounted on the saddle. The tool post may also have a milling function that rotates a rotary tool.

[0057] The processing machine 100 also has a first longitudinal frame 152, a second longitudinal frame 153, a first transverse frame 154, and a second transverse frame 311 (see below). Figure 3 ).

[0058] The first longitudinal frame 152 and the second longitudinal frame 153 have a column shape that extends along the length direction of the X-axis (vertical direction). The first longitudinal frame 152 and the second longitudinal frame 153 are arranged separately from each other in the Z-axis direction. The lower ends of the first longitudinal frame 152 and the second longitudinal frame 153 are connected to the base 151.

[0059] The first horizontal frame 154 and the second horizontal frame 311 have beam shapes that extend along the Z-axis (left-right direction). The first horizontal frame 154 and the second horizontal frame 311 are constructed of tubular material with closed cross-sections forming a rectangular shape.

[0060] The first horizontal frame 154 and the second horizontal frame 311 are arranged separately from each other in the Y-axis direction. The first horizontal frame 154 is positioned offset from the second horizontal frame 311 in the +Y-axis direction. The two ends of the first horizontal frame 154 in the Z-axis direction are connected to the upper ends of the first vertical frame 152 and the second vertical frame 153, respectively. The two ends of the second horizontal frame 311 in the Z-axis direction are connected to the upper ends of the first vertical frame 152 and the second vertical frame 153, respectively.

[0061] The first longitudinal frame 152, the second longitudinal frame 153, the first transverse frame 154, and the second transverse frame 311 form a portal frame structure on the base 151.

[0062] The machining machine 100 also includes a saddle 161, a cross slide 162, and a ram 163.

[0063] The saddle 161 is supported by the base 151. The saddle 161 is located on the base 151 and is positioned between the first longitudinal frame 152 and the second longitudinal frame 153 in the Z-axis direction. The saddle 161 has a shape that rises upwards from the base 151 toward the first transverse frame 154 and the second transverse frame 311. The saddle 161 is configured to move in the Z-axis direction using various conveying mechanisms, guiding mechanisms, and servo motors provided on the base 151, etc.

[0064] The cross slide 162 is supported by the saddle 161. The cross slide 162 is generally flat and parallel to the X-axis-Z-axis plane. The cross slide 162 is mounted on the front surface of the saddle 161 facing the +Y-axis direction. The cross slide 162 is configured to move in the X-axis direction (vertical direction) using various conveying mechanisms, guiding mechanisms, and servo motors provided to the saddle 161, etc.

[0065] The ram 163 is supported by the cross slide plate 162. The ram 163 has a cylindrical shape extending along the Y-axis. The ram 163 is arranged such that it passes through the cross slide plate 162 in the Y-axis direction and protrudes into the processing area 110. The ram 163 is configured to move in the Y-axis direction using various conveying mechanisms, guiding mechanisms, and servo motors provided to the cross slide plate 162, etc.

[0066] The machining machine 100 also includes a tool spindle 121. The tool spindle 121 is disposed within the machining area 110. The tool spindle 121 is configured to hold a rotating tool for removal machining (milling) of the workpiece. A clamping mechanism (not shown) is provided on the tool spindle 121 to hold the rotating tool in a detachable manner. During milling of a workpiece using a rotating tool, the tool spindle 121 causes the held rotating tool to rotate about a rotation axis 503 parallel to the X-Z axis plane.

[0067] The tool spindle 121 is supported by the ram 163. The tool spindle 121 is connected to the top end of the ram 163 in the +Y axis direction. The tool spindle 121 can move in three dimensions within the machining area 110 by means of the movement of the saddle 161 in the Z axis direction, the movement of the cross slide 162 in the X axis direction, and the movement of the ram 163 in the Y axis direction.

[0068] The tool spindle 121 is also configured to rotate about a rotation axis 504 parallel to the Y-axis (B-axis rotation). The rotation range of the tool spindle 121 is preferably a reference posture with respect to the spindle end face 122 of the tool spindle 121 facing downwards (in... Figure 1 and Figure 2 The orientation shown is within ±90°. As an example, the rotation range of the tool spindle 121 is within ±120° relative to the reference orientation.

[0069] The machining machine 100 also has an automatic tool changer (ATC) 141 and a tool magazine 171.

[0070] Tool magazine 171 stores multiple rotary tools T used for milling the workpiece. Tool magazine 171 is located outside the machining area 110. Tool magazine 171 is located on the opposite side of machining area 110, separated from the first workpiece spindle 111 (first longitudinal frame 152). The first workpiece spindle 111 (first longitudinal frame 152) is arranged between tool magazine 171 and machining area 110 in the Z-axis direction.

[0071] The automatic tool changer 141 is configured to allow tool changing between the tool spindle 121 within the machining area 110 and the tool magazine 171 outside the machining area 110.

[0072] The automatic tool changer 141 is supported by the first cross frame 154. The automatic tool changer 141 can move in the Z-axis direction using various conveying mechanisms, guiding mechanisms, and servo motors provided on the first cross frame 154, etc.

[0073] More specifically, a rack 156 and a track 155 are provided in the first horizontal frame 154. The rack 156 and track 155 extend in the Z-axis direction. The range of the rack 156 and track 155 extending in the Z-axis direction includes the range of the machining area 110 in the Z-axis direction. A pinion (not shown) is provided in the automatic tool changer 141 that engages with the rack 156. A slider (not shown) is provided in the automatic tool changer 141 that engages with the track 155 while being able to slide in the Z-axis direction.

[0074] The pinion gear, which receives rotation from the servo motor, rotates in the forward or reverse direction, thereby moving the automatic tool changer 141 in the +Z-axis or -Z-axis direction. The automatic tool changer 141 can move between the inside and outside of the machining area 110.

[0075] The automatic tool changer 141 can move between the following positions: standby position ( Figure 1 The automatic tool changer 141 shown is located outside the machining area 110 and above the first workpiece spindle 111, where it is in standby position; it is located inside the machining area 110 at any coordinate in the Z-axis direction, where it exchanges tools with the tool spindle 121; and it is located outside the machining area 110 and opposite to the standby position, where it exchanges tools with the tool magazine 171.

[0076] The automatic tool changer 141 has a lifting arm 143 and two arms 144. The lifting arm 143 extends in an arm-like shape with its length along the X-axis (vertical direction). The lifting arm 143 can move up and down in the X-axis direction.

[0077] The double arms 144 extend in an arm-like shape, with gripping portions at both ends for holding the tool. The double arms 144 can rotate about a rotation axis 505 parallel to the Z-axis, and can slide axially along the rotation axis 505. At the aforementioned tool changing positions inside the machine and on the tool magazine side, the lifting arm 143 moves up and down, while the double arms 144 rotate and slide, thereby enabling the automatic tool changer 141 to change the tool.

[0078] The machining machine 100 also includes an auxiliary machining head 131. The auxiliary machining head 131 ejects material powder onto the workpiece and irradiates it with a laser, thereby performing auxiliary machining (directed energy deposition). The material powder can be metal powders such as stainless steel, tungsten-chromium-cobalt alloy, nickel-chromium-iron heat-resistant and corrosion-resistant alloy, or titanium. Furthermore, the material powder is not limited to metal powders.

[0079] The auxiliary processing head 131 has a head body 132 and a laser tool 133. Laser and material powder are introduced into the head body 132. The laser tool 133 emits laser light towards the workpiece and defines the laser irradiation area within the workpiece. The material powder introduced into the auxiliary processing head 131 is ejected towards the workpiece via a nozzle (not shown).

[0080] The machining machine 100 has multiple laser tools 133. The laser irradiation areas defined by the multiple laser tools 133 on the workpiece have different shapes and / or sizes. In the head body 132, any one of the multiple laser tools 133 is selectively mounted according to the conditions of the additional machining to be performed.

[0081] The auxiliary machining head 131 also has a disc portion 136. The disc portion 136 has a disc shape in the Y-axis direction that is the thickness direction. The disc portion 136 is connected to the head body 132. The disc portion 136 is located at a position where the front end of the head body 132 is bent at a right angle in the +Y-axis direction. The tool spindle 121 has a front surface portion 124 and a side surface portion 123. The front surface portion 124 faces the +Y-axis direction. The side surface portion 123 faces the +Z-axis direction in the reference posture of the tool spindle 121.

[0082] The auxiliary machining head 131 is provided in a manner that allows it to be detached from the tool spindle 121. The auxiliary machining head 131 is mounted on the tool spindle 121 with the head body 132 facing the side portion 123 and the disc portion 136 facing the front surface portion 124.

[0083] The auxiliary machining head 131 (disc portion 136) and the tool spindle (front surface portion 124) are equipped with a clamping mechanism that utilizes elastic force or the like. When the auxiliary machining head 131 is mounted relative to the tool spindle 121, the clamping mechanism is activated, thereby connecting the auxiliary machining head 131 to the tool spindle 121. The auxiliary machining head 131 is connected to the tool spindle 121, so that it can move integrally with the tool spindle 121 in the X-axis, Y-axis, and Z-axis directions.

[0084] Figure 3 and Figure 4 It means Figure 1 A three-dimensional diagram of the structure used to supply laser light and material powder to an additional processing head.

[0085] Reference Figures 1-4 The processing machinery 100 also includes a material powder supply device 341, a laser oscillation device 342, and a pipeline body 210.

[0086] A material powder supply device 341 and a laser oscillation device 342 are disposed outside the processing area 110. The material powder supply device 341 feeds material powder used for additional processing toward the additional processing head 131. The laser oscillation device 342 causes the laser used for additional processing to oscillate.

[0087] The pipeline 210 supplies material powder from the material powder supply device 341 to the auxiliary processing head 131, and supplies laser light from the laser oscillation device 342 to the auxiliary processing head 131. The pipeline 210 extends from the auxiliary processing head 131. The pipeline 210 is led out from the inside of the processing area 110 to the outside and is connected to the material powder supply device 341 and the laser oscillation device 342.

[0088] The pipeline body 210 is flexible and can be bent and deformed under external force. The pipeline body 210 includes: an optical fiber for guiding laser light; piping for guiding material powder; air piping that serves as a flow path for air; gas piping that serves as a flow path for inactive gases; cooling piping that serves as a flow path for refrigerant; electrical wiring; and a flexible conduit 211 for housing these.

[0089] Reference Figure 3 and Figure 4 The protective plate 181 has a sliding cover 351.

[0090] The sliding cover 351 has a flat plate shape that is parallel to the X-Z axis plane. The sliding cover 351 is disposed on the inner side of the machining area 110 (at the end of the machining area 110 in the Y-axis direction). The ram 163 extends from outside the machining area 110 through the sliding cover 351 into the machining area 110 in the Y-axis direction. The sliding cover 351 can slide and deform in response to the movement of the ram 163 in the X-axis and Z-axis directions.

[0091] A pipeline insertion hole 352 is provided in the sliding cover 351. The pipeline insertion hole 352 is formed by a through hole that passes through the sliding cover 351 in the Y-axis direction. The pipeline 210 (flexible tube 211) is inserted into the pipeline insertion hole 352 from the processing area 110, and then led out of the processing area 110.

[0092] The processing machine 100 also includes a pipeline support 221. The pipeline support 221 is located outside the processing area 110. The pipeline support 221 supports the pipeline 210 extending from within the processing area 110. The pipeline support 221 is positioned above the additional processing head 131. The pipeline support 221 is supported by a first cross frame 154 and a second cross frame 311.

[0093] The pipeline support 221 has a base 331, a pulley 332, and a helical spring (elastic member) 333.

[0094] The base 331 is mounted on the first horizontal frame 154 and the second horizontal frame 311. Viewed from above, the base 331 spans between the first horizontal frame 154 and the second horizontal frame 311. A pipeline 210 extending from the interior to the exterior of the processing area 110 is mounted on the base 331. The pipeline 210, mounted on the base 331, extends towards the material powder supply device 341 and the laser oscillation device 342 after passing through a CableBear (registered trademark) that is slidable in the Z-axis direction.

[0095] The pulley section 332 is supported by the base 331. The pulley section 332 is configured to rotate about a rotation axis 526 that is parallel to the X-axis direction (vertical direction) and to slide in the Y-axis direction.

[0096] One end of the helical spring 333 is connected to the pulley portion 332. The other end of the helical spring 333 is connected to the base 331 via a bracket 334. The helical spring 333 applies an elastic force in the Y-axis direction to the pulley portion 332. The helical spring 333 applies an elastic force to the pulley portion 332 in a direction away from the machining area 110 when viewed from above.

[0097] The flexible tube 211 is composed of a flexible tube. The flexible tube 211 extends between the interior and exterior of the processing area 110. One end 211p of the flexible tube 211 is disposed inside the processing area 110. The other end 211q of the flexible tube 211 is disposed outside the processing area 110.

[0098] A flexible tube 211 extending from the inside of the processing area 110 to the outside extends along the -Y axis on the base 331. The flexible tube 211 is wrapped around the pulley part 332 and rotated 180° to extend along the +Y axis. The other end 211q of the flexible tube 211 is fixed to the base 331 at the top end of the flexible tube 211 extending along the +Y axis.

[0099] The pulley section 332 and the coil spring 333 constitute the tension applying mechanism 335. The tension applying mechanism 335 applies tension to the pipeline body 210 (flexible tube 211) in a direction away from the auxiliary processing head 131 within the processing area 110. The tension applying mechanism 335 applies a pulling force to the pipeline body 210 (flexible tube 211) from the inside of the processing area 110 toward the outside.

[0100] With this structure, the deflection of the pipeline 210 within the processing area 110 can be suppressed. Furthermore, the pulley portion 332 slides in the Y-axis direction, thereby automatically adjusting the length of the pipeline 210 within the processing area 111 in accordance with the position of the auxiliary processing head 131.

[0101] Furthermore, the elastic component constituting the tension-applying mechanism 335 is not particularly limited; for example, a gas spring can be used instead of the helical spring 333.

[0102] The machining machine 100 also includes a first guide mechanism 370 and a second guide mechanism 360. The first guide mechanism 370 and the second guide mechanism 360 guide the pipeline support portion 221 along the Z-axis direction. The first guide mechanism 370 and the second guide mechanism 360 are arranged separately from each other in the Y-axis direction.

[0103] The pipeline support 221 also has a block 336. The block 336 is fixed to the base 331. The block 336 is opposite to the first cross frame 154 in the Y-axis direction.

[0104] The first guide mechanism 370 has a track 155 and a slider 372. The first guide mechanism 370 has two sets of tracks 155 and sliders 372. The track 155 is mounted on the first cross frame 154. The track 155 extends in the Z-axis direction. The slider 372 is mounted on a block 336. The slider 372 engages with the track 155 by means of a plurality of balls (not shown). The slider 372 and the track 155 together constitute a linear guide mechanism in the Z-axis direction.

[0105] The second guide mechanism 360 is positioned separately from the first guide mechanism 370 in the Y-axis direction. The second guide mechanism 360 has a track 312. The track 312 is mounted on the second cross frame 311. The track 312 extends in the Z-axis direction. The pipeline support 221 (base 331) is equipped with: a pair of first rollers that clamp the track 312 from both sides in the Y-axis direction and are rotatable about a rotation axis parallel to the X-axis direction; and a pair of second rollers that clamp the track 312 from both sides in the X-axis direction and are rotatable about a rotation axis parallel to the Y-axis direction.

[0106] Reference Figure 4 The processing machine 100 also has a connecting mechanism 380. The connecting mechanism 380 has a cylinder 382 and a block 381.

[0107] Block 381 is mounted on saddle 161. A pin insertion hole (not shown) is provided in block 381. Cylinder 382 is mounted on pipeline support 221. Cylinder 382 has a pin (not shown) that can move forward and backward in the Y-axis direction. When the pin of cylinder 382 is inserted into the pin insertion hole of block 381, the tool spindle 121 is connected to pipeline support 221. When the pin of cylinder 382 is pulled out of the pin insertion hole of block 381, the connection between tool spindle 121 and pipeline support 221 is released.

[0108] During additional machining of the workpiece, the connecting mechanism 380 connects the tool spindle 121 to the pipeline support 221, allowing the pipeline support 221, the tool spindle 121, and the additional machining head 131 to move integrally in the Z-axis direction. Conversely, during workpiece removal, the connection between the tool spindle 121 and the pipeline support 221 via the connecting mechanism 380 is released, allowing the pipeline support 221 and the additional machining head 131 to separate from the tool spindle 121, enabling the tool spindle 121 to move independently.

[0109] The pipeline support 221 is also configured to move in the Z-axis direction in a separate state from the tool spindle 121 (self-moving mechanism).

[0110] More specifically, a rack 156 is provided in the first horizontal frame 154. The rack 156 extends in the Z-axis direction. A servo motor 222 is provided in the pipeline body support 221. Figure 3 and Figure 4 Not shown in the image, please refer to the diagram. Figure 1 A pinion (not shown) is connected to the output shaft of the servo motor 222 and engages with the rack 156. When the connection between the tool spindle 121 and the pipeline support 221 is released by the connecting mechanism 380, the pinion, which receives rotation from the servo motor 222, rotates in the positive or negative direction, thereby moving the pipeline support 221 in the +Z-axis direction or the -Z-axis direction.

[0111] Figures 5-7 It is a schematic representation Figure 1 A front view of the machining process of a workpiece in a machining machine.

[0112] Reference Figures 5-7 The machining machine 100 also includes a laser tool storage section 191 and a head storage section 192. The laser tool storage section 191 is configured to store multiple laser tools 133. The head storage section 192 is configured to store an additional machining head 131 that is separate from the tool spindle 121 during workpiece removal.

[0113] The laser tool storage unit 191 and the head storage unit 192 are located outside the processing area 110. The laser tool storage unit 191 is positioned in the X-axis direction (vertical direction) between the first workpiece spindle 111 and the standby position of the automatic tool changer 141. The head storage unit 192 is positioned above the second workpiece spindle 116.

[0114] like Figure 5As shown, during the additional machining of workpiece W, the additional machining head 131 is mounted on the tool spindle 121. The tool spindle 121 moves in the X-axis, Y-axis, and Z-axis directions, so that the additional machining head 131 also moves integrally with the tool spindle 121 within the machining area 110. Thus, the machining position of the additional machining performed by the additional machining head 131 is three-dimensionally shifted. Furthermore, the tool spindle 121 rotates around the rotation axis 504, so that the additional machining head 131 also rotates integrally with the tool spindle 121 around the rotation axis 504. Therefore, the orientation (the direction of laser irradiation relative to the workpiece) of the additional machining performed by the additional machining head 131 can be freely varied.

[0115] The auxiliary machining head 131 moves in the Z-axis direction to a position opposite to the laser tool storage section 191, thereby allowing the laser tool 133 mounted on the auxiliary machining head 131 to be replaced with another laser tool 133 stored in the laser tool storage section 191.

[0116] like Figure 6 As shown, when removing workpiece W during the additional machining of workpiece W, the connection between the tool spindle 121 and the additional machining head 131 is released, and the connection between the pipeline support 221 and the saddle 161 is also released. The additional machining head 131, which is integral with the pipeline support 221, is moved from within the machining area 110 to the head storage section 192 outside the machining area 110 using a self-moving mechanism provided to the pipeline support 221.

[0117] On the other hand, the tool spindle 121, which is separated from the auxiliary machining head 131, is rotated 90° from its reference position around the rotation axis 504. The automatic tool changer 141 is moved from the standby position to the in-machine tool changing position within the machining area 110. The tool Ta held by the automatic tool changer 141 is mounted on the tool spindle 121. The automatic tool changer 141 is moved from the in-machine tool changing position to the standby position, thereby completing the mounting of the tool relative to the tool spindle 121.

[0118] Furthermore, the in-machine tool change position is appropriately set such that the amount of movement of the tool spindle 121 from its initial position at the start of the tool change to the in-machine tool change position is shortened. This in-machine tool change position can be selected from any coordinate in the Z-axis direction, or from multiple candidate coordinates in the Z-axis direction.

[0119] like Figure 7 As shown, during the removal process of workpiece W, with the auxiliary machining head 131 stored in the head storage section 192, the workpiece is milled using the tool Ta held to the tool spindle 121.

[0120] During this period, the automatic tool changer 141 is moved from the standby position to the tool magazine-side tool change position, and at the tool magazine-side tool change position, the tool Tb stored in the tool magazine 171 is moved toward the automatic tool changer 141. The automatic tool changer 141 holding the tool Tb is moved from the tool magazine-side tool change position to the standby position, thereby preparing for the next tool change in the tool spindle 121.

[0121] Next, the structure of the safety belt connection 750 and its surrounding cover used during maintenance of the machining machine 100 will be described.

[0122] Figure 8 and Figure 9 It is a three-dimensional drawing showing the appearance of the processing machinery. Figure 8 The front surface side of the machining machine 100 is shown in the diagram. Figure 9 The rear surface side of the machining machine 100 is shown. (Refer to...) Figure 8 and Figure 9 The processing machine 100 also has an outer cover 710. The outer cover 710 constitutes the appearance of the processing machine 100. An internal space 706 is formed on the inner side of the outer cover 710.

[0123] The outer cover 710 has a box shape, which has a front surface 710a facing the +Y axis, a rear surface 710b facing the -Y axis, a right side surface 710c facing the +Z axis, a left side surface 710d facing the -Z axis, and an upper surface 710e facing the +X axis (above).

[0124] Furthermore, if for Figure 1 To explain the relationship between the protective plate 181 and the outer cover 710, the protective plate 181 is basically located inside the outer cover 710. However, the door 711, located on the front surface 710a and openable and closable when accessing the interior of the processing area 110, constitutes both the protective plate 181 that forms the processing area 110 and the outer cover 710 that forms the appearance of the processing machine 100 when it is in the closed state. The interior space 706 and the processing area 110 are separated by the protective plate 181.

[0125] The processing machine 100 also includes a corridor 712 and a staircase 714. The corridor 712 is configured to be walkable for operators. The corridor 712 is located upwards, separate from the ground on which the processing machine 100 is mounted. The corridor 712 is located on the rear surface 710b. The corridor 712 extends from the rear surface 710b in the -Y-axis direction and along the Z-axis direction. The staircase 714 is provided on the corridor 712. The staircase 714 allows operators to access the corridor 712 and the treadle 716 (described later) (see reference). Figure 10 It is composed of the way of rising and falling between ) .

[0126] The outer cover 710 has an openable and closable cover 721. The cover 721 is disposed on the top (upper surface 710e) of the processing machine 100.

[0127] The outer cover 710 has multiple covers 721 (721A, 721B, 721C, 721D, 721E, 721F, 721G, 721H, 721I, 721J, 721K, 721L, 721M, 721N). The covers 721A, 721B, 721C, 721D, 721E, 721F, 721G, 721H, 721I, 721J, 721K, 721L, 721M, 721N are configured to open and close independently of each other.

[0128] Covers 721A, 721B, 721C, 721D, 721E, 721F, and 721G are disposed on the upper surface 710e. Covers 721A, 721B, 721C, 721D, 721E, 721F, and 721G are arranged in the listed order along the -Z axis. Covers 721A, 721B, 721C, 721D, 721E, 721F, and 721G are each constructed of sheet metal parallel to the Y-axis -Z-axis plane.

[0129] Cover portions 721H, 721I, 721J, 721K, 721L, and 721M are disposed at the corners of the upper surface 710e and the rear surface 710b. Cover portions 721H, 721I, 721J, 721K, 721L, and 721M are arranged in the listed order along the -Z axis. Cover portions 721H and 721M are each composed of sheet metal having three surfaces parallel to the Y-axis-Z-axis plane, the X-axis-Y-axis plane, and the X-axis-Z-axis plane. Cover portions 721I, 721J, 721K, and 721L are each composed of sheet metal having two surfaces parallel to the Y-axis-Z-axis plane and the X-axis-Z-axis plane.

[0130] Covers 721I, 721J, 721K, 721L, and 721M are respectively arranged adjacent to covers 721C, 721D, 721E, 721F, and 721G in the Y-axis direction.

[0131] A cover portion 721N is disposed on the upper surface 710e. Cover portion 721N is disposed adjacent to cover portion 721B in the Y-axis direction. Cover portion 721H is disposed adjacent to cover portion 721N in the Y-axis direction. Cover portion 721N is located between cover portions 721B and cover portion 721H in the Y-axis direction. Cover portion 721N is constructed of a sheet metal parallel to the Y-axis-Z-axis plane.

[0132] Figure 10 It indicates that it is used for support. Figure 9 A three-dimensional diagram of the frame structure of the outer casing. Figure 10In the middle, the outer cover 710 at the upper surface 710e and the rear surface 710b was partially removed.

[0133] Reference Figure 9 and Figure 10 The processing machine 100 also includes multiple first column portions 741, pedals 716, multiple second column portions 742, first beam portions (frame portions) 751, and multiple second beam portions 746. The multiple first column portions 741, pedals 716, multiple second column portions 742, first beam portions 751, and multiple second beam portions 746 are disposed in the internal space 706 inside the outer cover 710.

[0134] The foot pedal 716 is positioned upwards, separate from the ground where the processing machine 100 is located. The foot pedal 716 is positioned offset from the corridor 712 in the +Y-axis direction and the +X-axis direction (upwards). The foot pedal 716 is located inside the covers 721H, 721I, 721J, 721K, 721L, 721M, and 721N. The foot pedal 716 is constructed of a plate material parallel to the Y-axis-Z-axis plane. The foot pedal 716 extends along the Z-axis direction.

[0135] The first column portion 741 has a column shape extending upward from the ground where the processing machine 100 is installed. Multiple first column portions 741 are arranged in a spaced-apart manner in the Z-axis direction. The upper ends of the multiple first column portions 741 are connected to the pedal 716. The multiple first column portions 741 support the pedal 716.

[0136] The first beam portion 751 is positioned upwards, separated from the pedal 716. The first beam portion 751 is opposite to the pedal 716 in the X-axis direction. The first beam portion 751 extends in the horizontal direction. The first beam portion 751 has a beam shape extending along the Z-axis direction.

[0137] The first beam 751 is made of a closed-section tube. The first beam 751 has a rectangular closed-section when cut by a plane orthogonal to the Z-axis direction.

[0138] The length region of the processing area 110 in the Z-axis direction is included in the length region of the first beam portion 751 in the Z-axis direction. The first beam portion 751 is located above the pipeline support portion 221. In the Y-axis direction, the first beam portion 751 is located closer to the rear surface 710b of the outer cover 710 than to the front surface 710a. The first beam portion 751 is located offset from the pipeline support portion 221 in the -Y-axis direction. When viewed from above, the first beam portion 751 extends along a straight line that overlaps with the boundaries between the plurality of covers 721B, 721C, 721D, 721E, 721F, 721G and the plurality of covers 721N, 721I, 721J, 721K, 721L, 721M.

[0139] The second beam portion 746 has a beam shape extending in the Y-axis direction. Multiple second beam portions 746 are arranged with intervals between them in the Z-axis direction. The end (rear end) of the second beam portion 746 in the Y-axis direction is opposite to the first beam portion 751.

[0140] Multiple second column portions 742 have a column shape extending upward from the pedal 716. The multiple second column portions 742 are arranged with intervals between them in the Z-axis direction. The upper ends of the multiple second column portions 742 are connected to the first beam portion 751 and the multiple second beam portions 746. The multiple second column portions 742 support the first beam portion 751 and the multiple second beam portions 746.

[0141] Cover portions 721A, 721D, 721E, 721F, 721G, 721N, 721I, 721J, 721K, 721L, and 721M are supported by the first beam portion 751. The rear ends (rear ends) of cover portions 721A, 721D, 721E, 721F, and 721G in the -Y axis direction are mounted on the first beam portion 751. The front ends (front ends) of cover portions 721N, 721I, 721J, 721K, 721L, and 721M in the +Y axis direction are mounted on the first beam portion 751 (see also the following description). Figure 14 ).

[0142] Figure 11 It means Figure 10 An exploded assembly drawing of the seatbelt connection portion within the area enclosed by the double-dotted line XI. Figure 12 It means Figure 10 A diagram illustrating how to use the seatbelt connector. (Refer to...) Figures 10-12 The processing machine 100 has a safety belt connection part 750.

[0143] The seat belt connector 750 has a first beam 751 and a rope 756. The rope 756 is laid along the first beam 751. The rope 756 extends in the Z-axis direction.

[0144] Rope 756 is fixed to the first beam 751. Multiple flaps 752 are mounted on the first beam 751. The flaps 752 are positioned separately in the Z-axis direction. Rope insertion holes 753 are provided on the flaps 752. Both ends of the rope 756 are mounted to the flaps 752 with the rope insertion holes 753 inserted into them.

[0145] The safety belt 761 is a protective device to prevent workers from falling while working at heights. The safety belt connector 750 is configured to connect to the safety belt 761 that has been installed on the worker.

[0146] More specifically, the worker hooks the hook 762, which is attached to the safety belt 761, onto the rope 756, thereby connecting the safety belt 761 to the safety belt connection part 750. The worker can move along the Z-axis direction of the rope 756 while keeping the hook 762 hooked onto the rope 756.

[0147] In this embodiment, the first beam 751 is made of a closed-section tube, which can sufficiently improve the rigidity of the seat belt connection 750.

[0148] Furthermore, the structure of the seat belt connection 750 is not limited to the above structure. For example, it can also be structured as follows: the rope 756 is not fixed to the first beam 751, and the hook 762 of the seat belt 761 is directly hooked to the first beam 751.

[0149] Figure 13 It means Figure 9 A perspective view of a machining machine with its cover in the open position. Figure 14 It means along Figure 9 A cross-sectional view of the machining equipment viewed in the direction of sight along the XIV-XIV line. Figure 15 It means along Figure 9 A cross-sectional view of the machining equipment viewed in the direction of sight along the XV-XV line.

[0150] Reference Figure 9 and Figures 13-15 The machining machine 100 also includes a first support portion 770. The first support portion 770 supports the cover portions 721B and 721C so that they can slide. The first support portion 770 supports the cover portions 721B and 721C so that they can slide in the Z-axis direction.

[0151] like Figure 13 and Figure 14 As shown, the first support portion 770 has a first track 771, a first rotating roller 774, and a second rotating roller 775. The end portion (rear end portion) of the cover portion 721A in the Y-axis direction is supported by the first track 771, the first rotating roller 774, and the second rotating roller 775.

[0152] The first track 771 extends in the Z-axis direction, spanning between cover portion 721A and cover portion 721D. The first track 771 is supported by cover portion 721A and cover portion 721D. The first track 771 is provided with a first groove portion 772 and a second groove portion 773. The first groove portion 772 opens toward the +Y axis direction and extends in the Z-axis direction. The second groove portion 773 opens toward the +X axis direction (upward) and extends in the Z-axis direction.

[0153] The first rotating roller 774 and the second rotating roller 775 are mounted on the cover portion 721B. The first rotating roller 774 is configured to rotate around a rotation axis 541 extending in the Y-axis direction. The first rotating roller 774 is fitted into the first groove portion 772. The second rotating roller 775 is configured to rotate around a rotation axis 542 extending in the X-axis direction. The second rotating roller 775 is fitted into the second groove portion 773.

[0154] like Figure 15 As shown, the first support portion 770 also has a second track 776 and a third rotating roller 778. The end portion (front end portion) of the cover portion 721A in the +Y axis direction is supported by the second track 776 and the third rotating roller 778.

[0155] The second track 776 extends in the Z-axis direction. A third groove 777 is provided in the second track 776. The third groove 777 opens toward the -Y-axis direction and extends in the Z-axis direction. The third rotating roller 778 is provided in a manner that allows it to rotate about a rotation axis 543 extending in the Y-axis direction. The third rotating roller 778 is fitted into the third groove 777.

[0156] Based on this structure, the cover portion 721B is configured to slide in the Z-axis direction. Additionally, multiple rotating rollers corresponding to the first rotating roller 774, the second rotating roller 775, and the third rotating roller 778 are also installed on the cover portion 721C. The cover portion 721C is configured to slide in the Z-axis direction using the same support structure as the cover portion 721A.

[0157] like Figure 9 and Figure 13 As shown, with cover portions 721B and 721C in the closed state, cover portions 721B and 721C abut against each other in the Z-axis direction. Cover portion 721B slides in the +Z-axis direction and is positioned above cover portion 721A, while cover portion 721C slides in the -Z-axis direction and is positioned above cover portion 721D, thus setting cover portions 721B and 721C to the open state.

[0158] Reference Figure 9 and Figure 13 The machining machine 100 also has a second support portion 726. The second support portion 726 supports the cover portion 721H so that it is rotatable. The second support portion 726 supports the cover portion 721H so that it can rotate about a rotation axis 531 parallel to the X-axis direction (vertical direction). For example, multiple hinges 727 are used in the second support portion 726.

[0159] When the cover 721H is closed, it is positioned parallel to the cover 721I in the Z-axis direction. When the cover 721H rotates about the rotation axis 531 and separates from the cover 721I, it is in the open state.

[0160] With the cover 721N in the closed state, the cover 721N is mounted to the outer cover 710 and the first beam 751 adjacent to the cover 721N using bolts (not shown). By loosening the bolts, the cover 721N is removed from the outer cover 710 and the first beam 751, thereby setting the cover 721N to the open state.

[0161] Figure 16 It is a perspective view showing the positional relationship between the opening, the safety belt connection, and the pipeline support when the cover is in the open position.

[0162] Reference Figure 13 and Figure 16 With cover portions 721B, 721C, 721H, and 721N in the open state, an opening 780 is formed in the outer cover 710. The internal space 706 communicates with the space outside the internal space 706 through the opening 780. The opening 780 opens in the +X axis direction (upward) and the -Y axis direction.

[0163] The seatbelt connection 750 is exposed to the outside of the interior space 706 via the opening 780. A portion of the length region of the first beam 751 and the rope 756 in the Z-axis direction is exposed to the outside of the interior space 706. The seatbelt connection 750 is opposite to the opening surface formed by the opening 780 in the Y-axis and X-axis directions.

[0164] The first beam portion 751 extends along the opening surface formed by the opening portion 780 in the Z-axis direction. The first beam portion 751 is positioned directly below the opening surface formed by the opening portion 780.

[0165] With cover portions 721B, 721C, 721H, and 721N in the open state, the pipeline support portion 221 is exposed to the outside of the internal space 706 via the opening 780. The pipeline support portion 221 faces the opening surface formed by the opening 780 in the X-axis direction. The space on the pipeline support portion 221 is open in the +X-axis direction (upward) via the opening 780.

[0166] With covers 721B, 721C, 721H, and 721N in the open state, pedal 716 is exposed to the outside of the interior space 706 via opening 780. Pedal 716 is opposite to the opening surface formed by opening 780 in the X-axis direction. The space on pedal 716 is open to the -Y-axis direction and the +X-axis direction (upward) via opening 780.

[0167] When viewed from above, the pipeline support 221 is located on the opposite side of the pedal 716, separated by the safety belt connection 750 (first beam 751 and rope 756).

[0168] Reference Figure 9 , Figure 13 as well as Figure 16 There are situations where maintenance is required for the pipeline support portion 221, including the tension applying mechanism 335, the connecting mechanism 380, the first guiding mechanism 370, and the second guiding mechanism 360.

[0169] In this situation, the operator moves the pipeline support 221 in the Z-axis direction, positioning it directly below the covers 721B and 721C. The operator stands on the top of the stairs 714 via the corridor 712 and the stairs 714.

[0170] The operator rotates cover 721H around rotation axis 531 and removes cover 721N from outer cover 710, thereby setting cover 721H and cover 721N to the open state. The operator slides cover 721B in the +Z axis direction and slides cover 721C in the -Z axis direction, thereby setting cover 721B and cover 721C to the open state.

[0171] The worker hooks the safety belt 761 (attached to their body) 762 onto the rope 756 of the safety belt connector 750. The worker then performs maintenance on the pipeline support 221 through the opening 780.

[0172] In this embodiment, the outer cover 710 is provided with openable and closable covers 721B, 721C, 721H, and 721N, and the safety belt connection portion 750 is located at a position exposed to the outside of the internal space 706 via an opening 780 created when these covers 721B, 721C, 721H, and 721N are in the open state. Therefore, by opening the covers 721B, 721C, 721H, and 721N, the worker can hook the hook 762 of the safety belt 761, which is installed on their body, onto the rope 756 of the safety belt connection portion 750. This provides good operability for the worker when using the safety belt 761.

[0173] Furthermore, the seat belt connector 750 is disposed inside the outer casing 710 that constitutes the appearance of the machining machine 100. Therefore, the seat belt connector 750 does not affect the maximum mechanical size (height) of the machining machine 100, and the machining machine 100 can be miniaturized.

[0174] Furthermore, in this embodiment, cover portions 721B and 721C are supported in a sliding manner, and cover portion 721H is supported in a rotatable manner. With this structure, cover portions 721B, 721C, and 721H can be easily opened and closed, thus further improving operability for workers using the safety belt 761.

[0175] Furthermore, the cover 721N is supported by the first beam 751 of the seatbelt connecting portion 750. With this structure, the first beam 751 is positioned close to the back of the cover 721N, thus easily allowing the seatbelt connecting portion 750 to be exposed via the opening 780 created when the cover 721N is in the open state. Moreover, by sharing the first beam 751 used to support the outer cover 710 with the seatbelt connecting portion 750 used to connect the seatbelt 761, a reduction in the number of components can be achieved.

[0176] Furthermore, the first beam portion 751 extends in one direction along the opening surface formed by the opening portion 780. Therefore, it is possible to prevent the first beam portion 751 from blocking the opening surface formed by the opening portion 780 to a large extent. As a result, it is easy for operators to perform maintenance on the pipeline support portion 221 via the opening portion 780.

[0177] Furthermore, in this embodiment, the case in which the pipeline support 221 is maintained by setting the covers 721B, 721C, 721H, and 721N of the plurality of covers 721 to the open state is described, but this is only an example.

[0178] The object to be maintained is not limited to the pipeline support 221; for example, it could also be the automatic tool changer 141 or the sliding cover 351. The covers 721, other than 721B, 721C, and 721H, are bolted to the main body of the machining equipment 100, such as the first beam 751 and the second beam 746. The covers 721, other than 721B, 721C, and 721H, can be removed from the main body of the machining equipment 100 by loosening the bolts. Depending on the location of the object to be maintained, the operator can open at least one of the covers 721, thereby enabling the provision of an opening at an appropriate location.

[0179] Summarizing the above description of the structure of the processing machine 100 in the embodiments of the present invention, the processing machine 100 in this embodiment includes: an outer cover 710, which constitutes the appearance of the processing machine 100 and is used to divide and form an internal space 706; and a seat belt connecting portion 750, which is disposed in the internal space 706 and can be connected to a seat belt 761. The outer cover 710 includes an openable and closable cover portion 721. The seat belt connecting portion 750 is exposed to the outside of the internal space 706 through an opening formed in the outer cover 710 when the cover portion 721 is in the open state.

[0180] The processing machine 100 according to the embodiment of the present invention, configured in this way, enables good operability for the operator when using the safety belt 761, and also enables the processing machine 100 to be miniaturized.

[0181] Furthermore, this embodiment describes an AM / SM hybrid machining center based on a combination machine tool with turning and milling functions, but it is not limited to this structure. For example, an AM / SM hybrid machining center can also be based on a machining center with milling functions. Additionally, the present invention is not limited to AM / SM hybrid machining centers, but can also be applied to lathes, machining centers, or combination machine tools with turning and milling functions.

[0182] It should be considered that the embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the invention is defined not by the foregoing description but by the claims, and is intended to include all modifications within the same meaning and scope as the claims.
