[0002] In the prior art, a machine tool that processes a workpiece using a tool is provided with a tool magazine for storing a plurality of tools, and the required tools are exchanged according to the processing conditions, so as to efficiently perform the processing. As an example, in Patent Document 1, a tool magazine is provided on a workbench that holds the workpiece, and in a processing step, the tool magazine moves to a position away from a spindle on which the tool is mounted, and in a tool changing step, the tool magazine moves to a position close to the spindle so that the tool mounted on the spindle can be exchanged with the tool in the tool magazine.

[0003] However, in Patent Document 1, the spindle support for supporting the spindle is arranged behind the tool magazine. Therefore, in order to ensure the moving range of the tool magazine, the size of the machine tool in the moving direction of the tool magazine must be increased, resulting in a larger structure of the machine tool.

[0068] Examples of exemplary embodiments of the present invention are now illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and description to refer to the same or similar parts. Figures 1 to 6 To illustrate the specific structure and operation process of the machine tool 100 in this embodiment and the machine tool 100A in its variation, but this is only one example of the present invention. The specific structure and operation process of the machine tool 100 and the machine tool 100A can be adjusted according to needs, and the present invention is not limited to this.

[0069] Please refer to Figures 1 to 3 In this embodiment, the machine tool 100 includes a spindle 110, a workpiece support 120, a tool magazine 130, a first moving mechanism 140, and a spindle support 150. The spindle 110 is used to mount a tool 20. The workpiece support 120 is used to support a workpiece (not shown) to be machined by the tool 20 mounted on the spindle 110. The tool magazine 130 is arranged on the workpiece support 120 to hold a plurality of tools 20 (in Figure 2 6 tools are shown in the figure, but this is not limiting). The first moving mechanism 140 moves the workpiece support 120 in a first direction (e.g., the front-rear direction Y). The spindle support 150 supports the spindle 110. In the second direction (e.g., the left-right direction X) orthogonal to the first direction (e.g., the front-rear direction Y), the tool magazine 130 is movable in a position overlapping with at least a portion of the spindle support 150 (corresponding to Figure 1In this way, the workpiece support 120 is moved by the first moving mechanism 140, so that the tool magazine 130 provided on the workpiece support 120 also moves synchronously, and the moving range of the tool magazine 130 is set to overlap with at least a part of the spindle support 150 when viewed from the side (i.e., viewed from the second direction (e.g., the left-right direction X)). Therefore, not only can the moving range of the tool magazine 130 be ensured, but also the size of the machine tool 100 can be reduced and the structure can be miniaturized. The following is a detailed description of each component.

[0070] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the workpiece support 120 is connected to the first moving mechanism 140. The first moving mechanism 140, for example, includes a first guide portion 142 (for example, a combination of a linear guide rail and a ball screw) extending in a first direction (front-rear direction Y), and a driving portion (for example, a motor (not shown)) for moving the workpiece support 120 along the first guide portion 142, so that the workpiece support 120 moves in the first direction (front-rear direction Y). In this way, the workpiece support 120 can move in a processing area (for example, the front side of the tool magazine 130) according to the processing conditions required for the supported workpiece. Although the movement of the workpiece support 120 in the front-rear direction Y is used as an example of the first direction, for example, the workpiece support 120 can also be configured to move in other directions, and the workpiece support 120 can also be configured to move in multiple directions through other moving mechanisms not shown. Furthermore, although the first guide portion 142 and the driving portion are used as examples of the first moving mechanism 140, the present invention does not limit the composition of the first moving mechanism 140, which can be adjusted according to needs.

[0071] Furthermore, in this embodiment, if Figure 1 and Figure 2As shown, the workpiece support 120 includes, for example, a worktable 122 and a rotating mechanism 124. The worktable 122 is used to fix the workpiece, and the rotating mechanism 124 allows the worktable 122 to rotate with a horizontal direction (for example, a left-right direction X) as a rotation axis A. Among them, the rotating mechanism 124 is, for example, arranged on a first moving mechanism 140 through a base 126, and the worktable 122 is arranged on the rotating mechanism 124. The entire workpiece support 120 can be moved by the first moving mechanism 140, and the worktable 122 of the workpiece support 120 can also be rotated by the rotating mechanism 124. In this way, the workpiece support 120 can have the operating functions of linear movement and rotation along the horizontal axis, thereby having a more diverse processing method. Although the worktable 122 is rotated with the left-right direction X as the rotation axis A as an example of the horizontal direction, the worktable 122 can also rotate with other horizontal directions or vertical directions as the rotation axis. In addition, although the worktable 122 and the rotating mechanism 124 are used as examples of the workpiece support 120, only the worktable 122 can be provided. The present invention does not limit the composition of the workpiece support portion 120 , which can be adjusted according to needs.

[0072] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the tool magazine 130 accommodates a plurality of tools 20. The tool magazine 130, for example, includes a tool holder 132 that supports a plurality of tools 20, and a magazine cover 134 that covers the periphery of the tool holder 132 and can be opened and closed. Figure 2 As shown, the tool handle 132 is provided with a plurality of clamps 132a capable of clamping the tool 20, and the opening of the clamp 132a is open toward the front side of the front-back direction Y, so that the tool 20 can be supported on the tool handle 132 by the clamping of these clamps 132a. Among them, the tool handle 132 of the tool magazine 130 supports the plurality of tools 20 to be arranged in a single row in the left-right direction X. In this way, the required tool 20 can be selected for tool change (as described later) by the relative movement of the spindle 110 for mounting the tool 20 and the tool magazine 130 for accommodating the tool 20 in the left-right direction X. Although six clamps 132a are provided on the tool handle 132 to support six tools 20 as an example, the number of tools 20 and the clamps 132a can be adjusted according to demand. In addition, the means for supporting the tool 20 of the tool handle 132 is not limited to the clamp 132a, but can also be other supporting components capable of supporting the tool 20. Furthermore, although the tool holder 132 is used as an example to support the plurality of tools 20 so as to be arranged in a single row in the left-right direction X, the tool holder 132 may also support the plurality of tools 20 so as to be arranged in a single row in other directions, or support the plurality of tools 20 so as to be arranged in a matrix. The present invention does not limit the embodiment of the tool magazine 130 using the tool holder 132 to support the tools 20, which may be adjusted according to needs. In addition, the magazine cover 134 is closed during the processing process of the machine tool 100 (e.g., Figure 1 134 is opened during the tool changing process of the machine tool 100 (as shown in FIG. Figure 2 As shown), the tool 20 mounted on the spindle 110 can be replaced with other tools 20 supported by the tool holder 132.

[0073] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the tool magazine 130 is arranged on the workpiece support part 120 and can move synchronously with the workpiece support part 120. As an example, in addition to the tool handle 132 and the magazine cover 134, the tool magazine 130 also includes a support component 136 that supports the tool handle 132, and the tool handle 132 and the magazine cover 134 are arranged on the workpiece support part 120 (for example, arranged on the aforementioned base 126) through the support component 136. In the process that the first moving mechanism 140 moves the workpiece support part 120 in the first direction (front-rear direction Y), the tool magazine 130 also moves in the first direction (front-rear direction Y), so that the positions of the workpiece support part 120 and the tool magazine 130 can be adjusted according to the working process of the machine tool 100. Although the support component 136 is used as an example of setting the tool magazine 130 on the workpiece support part 120, other components can also be used to set the tool magazine 130 on the workpiece support part 120, or the tool handle 132 of the tool magazine 130 can be directly set on the workpiece support part 120. The present invention does not limit the implementation method in which the tool magazine 130 and the workpiece support 120 move synchronously in the first direction, which can be adjusted according to needs.

[0074] Furthermore, in this embodiment, the tool magazine 130 and the workpiece support 120 are arranged in a first direction, so that the positions of the workpiece support 120 and the tool magazine 130 in the first direction can be adjusted according to the working process of the machine tool 100. In the case where the first direction is the front-to-back direction Y, the tool magazine 130 is, for example, arranged behind the workpiece support 120. When the machine tool 100 performs a processing process, the workpiece support 120 is moved to a position corresponding to the spindle 110 (such as Figure 1 As shown in FIG. 1 ). Thus, the workpiece supported on the workpiece support 120 can be processed. When the machine tool 100 performs a tool change process, the workpiece support 120 is moved to a position ahead of the processing process by the first moving mechanism 140, and the tool magazine 130 is moved to a position corresponding to the spindle 110 (as shown in FIG. 1 ). Figure 2As shown). Thus, it is possible to change tools with the tool 20 accommodated in the tool magazine 130. Therefore, the workpiece support 120 and the tool magazine 130 can be arranged at positions adjacent to each other, so that the above-mentioned moving range in the first direction is shortened, and the size of the machine tool 100 in the first direction is also reduced. In this way, the moving range of the tool magazine 130 can be designed according to the position of the tool magazine 130, so that the machine tool 100 can improve the tool change efficiency and miniaturize the structure. Although the workpiece support 120 and the tool magazine 130 are arranged adjacent to each other in the first direction and the tool magazine 130 is arranged behind the workpiece support 120 as an example, the relative position of the workpiece support 120 and the tool magazine 130 can be adjusted according to needs. For example, the tool magazine 130 can also be arranged on one of the left or right sides of the workpiece support 120.

[0075] In addition, in this embodiment, if Figure 1 As shown, the magazine cover 134 includes a first cover 134A and a second cover 134B that are arranged opposite to each other in a first direction (front-rear direction Y) and can be opened and closed relatively. The tool magazine 130 moves in a direction away from the spindle 110 (e.g., rearward) during the processing process of the machine tool 100, and the workpiece supported on the workpiece support 120 is processed using the tool 20 installed on the spindle 110. At this time, the magazine cover 134 is closed during the processing process of the machine tool 100 (i.e., the first cover 134A and the second cover 134B overlap each other and cover the periphery of the tool holder 132), thereby preventing chips and the like from adhering to the tool 20 supported by the tool holder 132. In contrast, as Figure 2 As shown, the tool magazine 130 moves toward the direction close to the spindle 110 (e.g., forward) during the tool changing process of the machine tool 100, so that the tool 20 installed on the spindle 110 is replaced with the tool 20 accommodated in the tool magazine 130. At this time, the magazine cover 134 is opened during the tool changing process of the machine tool 100 (i.e., at least a portion of the first cover 134A and the second cover 134B are separated from each other to form an opening to expose the tool 20 supported by the tool holder 132), so that the tool 20 installed on the spindle 110 can be replaced with other tools 20 supported by the tool holder 132. Therefore, not only the movement of the tool magazine 130 is linked to the movement of the workpiece support 120, but also the opening and closing operation of the magazine cover 134 is further linked to the movement of the tool magazine 130. In this way, the tool magazine 130 can close the magazine cover 134 to protect the tool 20 supported by the tool holder 132 during the machining process, and open the magazine cover 134 to perform tool replacement during the tool replacement process.

[0076] As an example, in this embodiment, the machine tool 100 further includes an opening and closing mechanism 160, which opens or closes the magazine cover 134 during the movement of the tool magazine 130. The opening and closing mechanism 160 includes a cam 162 and a connecting rod component 164. The cam 162 is, for example, located on a fixed structure of the machine tool 100 (such as the base 190 described later), and the connecting rod component 164 is connected to the magazine cover 134 and is opposite to the cam 162 in a first direction (front-rear direction Y). The connecting rod component 164 approaches and abuts against the cam 162 during the movement of the tool magazine 130, thereby causing the magazine cover 134 to be opened or closed from a closed state (corresponding to the front-rear direction Y). Figure 1 The first operating state) is shifted to the open state (corresponding to Figure 2 In addition, the link member 164 moves away from the cam 162 during the movement of the tool magazine 130, thereby causing the magazine cover 134 to move from the open state (corresponding to the second operating state). Figure 2 The second operating state) is shifted to the closed state (corresponding to Figure 1 In this way, the opening and closing operation of the magazine cover 134 is linked to the movement of the tool magazine 130 driven by the workpiece support part 120 through the opening and closing mechanism 160, so that the magazine cover 134 can be opened more efficiently in the tool changing process. Although the opening and closing mechanism 160 includes a cam 162 and a connecting rod component 164 as an example, the opening and closing mechanism 160 can also use other components for opening or closing the magazine cover 134, or use a motor to open and close the magazine cover 134. Alternatively, the setting of the opening and closing mechanism 160 can also be omitted. The present invention does not limit the specific composition, operation mode and setting of the opening and closing mechanism 160. Furthermore, although the magazine cover 134 includes a first cover 134A and a second cover 134B as an example, the magazine cover 134 can also have only the first cover. As long as the magazine cover 134 can cover the periphery of the tool handle 132 and can be opened or closed during the movement of the tool magazine 130, the present invention does not limit the specific structure and operation mode of the magazine cover 134. In addition, although the tool magazine 130 is taken as an example including a tool handle 132 and a magazine cover 134, as long as the tool magazine 130 can support multiple tools 20 and provide replaceable tools 20 in the tool changing process, the present invention does not limit the specific structure of the tool magazine 130, which can be adjusted according to needs.

[0077] Furthermore, in this embodiment, if Figure 1 and Figure 2As shown, the spindle 110 for mounting the tool 20 is arranged on a side away from the workpiece support 120 and the tool magazine 130 in the vertical direction Z. For example, the spindle 110 is supported by the spindle support 150 and is located at a position higher than the workpiece support 120 and the tool magazine 130 in the vertical direction Z. In addition, the spindle 110 for mounting the tool 20 is, for example, movable in a second direction (for example, the left-right direction X) orthogonal to the first direction (the front-back direction Y). As an example, the machine tool 100 further includes a second moving mechanism 170. The second moving mechanism 170 includes a second guide portion 172 (for example, a combination of a linear guide and a ball screw) extending in the left-right direction X, and a driving portion (for example, a motor (not shown)) for moving the spindle 110 along the second guide portion 172, so that the spindle 110 is movable in the left-right direction X. It can be seen that when the machine tool 100 performs a tool changing process, the spindle 110 moves in the left-right direction X, and one of the multiple tools 20 arranged in a single row along the left-right direction X on the tool holder 132 can be selected for tool changing. In this way, the spindle 110 can have a linear movement operation function. Although the second guide portion 172 and the drive portion are used as examples of the second moving mechanism 170, the present invention does not limit the composition of the second moving mechanism 170. Furthermore, although the movement of the spindle 110 in the left-right direction X is used as an example of the second direction, the present invention does not limit the moving direction of the spindle 110.

[0078] For example, in this embodiment, if Figure 1 and Figure 2, the spindle 110 is movable in a third direction (e.g., up-down direction Z) orthogonal to the first direction (front-back direction Y) and the second direction (e.g., left-right direction X). As an example, the machine tool 100 further includes a third moving mechanism 180. The third moving mechanism 180 includes a third guide portion 182 (e.g., a combination of a linear guide and a ball screw) extending in the up-down direction Z, and a driving portion (e.g., a motor (not shown)) for moving the spindle 110 along the third guide portion 182, so that the spindle 110 is movable in the up-down direction Z. It can be seen that the spindle 110 can move downward and approach the workpiece support portion 120 during the machining process, and use the installed tool 20 to machine the workpiece supported on the workpiece support portion 120. In addition, the spindle 110 can move downward and approach the tool magazine 130 during the tool changing process, and change the tool with the tool 20 accommodated in the tool magazine 130. The positions of the workpiece support 120 and the tool magazine 130 in the first direction (front-rear direction Y) are adjusted by the movement of the first moving mechanism 140 (as described above), so that the spindle 110 can perform processing or tool change according to the working process of the machine tool 100. In this way, the spindle 110 can have a linear movement operation function. Although the third guide portion 182 and the drive portion are used as examples of the third moving mechanism 180, the present invention does not limit the composition of the third moving mechanism 180. Furthermore, although the spindle 110 moves in the up-down direction Z as an example of the third direction, the present invention does not limit the moving direction of the spindle 110. In particular, although the spindle 110 is movable in both the up-down direction Z and the left-right direction X as an example, the spindle 110 may be movable in only one of the linear directions. In addition, although the spindle 110 is movable as an example, it may also be set to be immovable. In this case, the processing process and the tool change process are implemented by the movable workpiece support 120 and the movable tool magazine 130. The present invention is not limited to the above-described embodiments.

[0079] In addition, in this embodiment, Figure 1 and Figure 2As shown, the spindle support 150 supports the spindle 110. At least a portion of the spindle support 150 extends in the up-down direction Z to support the spindle 110 at a position higher than the workpiece support 120 and the tool magazine 130. Furthermore, when the machine tool 100 is provided with a second moving mechanism 170 and a third moving mechanism 180 so that the spindle 110 is movable in the left-right direction X as the second direction and the up-down direction Z as the third direction, the spindle support 150 also supports the second moving mechanism 170 and the third moving mechanism 180, thereby supporting the spindle 110 that is provided on the second moving mechanism 170 and the third moving mechanism 180 and is movable. As an example, when the first direction is the front-rear direction Y, the spindle support part 150 is, for example, arranged behind the workpiece support part 120, the second moving mechanism 170 extends in the second direction (left-right direction X) and is supported by the spindle support part 150 at a position higher than the workpiece support part 120 and the tool magazine 130, the third moving mechanism 180 extends in the third direction (up-down direction Z) and is arranged on the second moving mechanism 170, and the spindle 110 is arranged on the third moving mechanism 180. In this way, the spindle 110 is located at a position higher than the workpiece support part 120 and the tool magazine 130. Although the second moving mechanism 170 and the third moving mechanism 180 are also supported by the spindle support part 150 as an example, the spindle 110 can also be directly installed on the spindle support part 150 through a mounting structure not shown. The present invention is not limited to the above-mentioned embodiment.

[0080] Furthermore, in this embodiment, if Figure 1 and Figure 2As shown, the machine tool 100 also includes a base 190. The base 190 serves as the base of the machine tool 100 to support the workpiece support 120. For example, the base 190 supports the workpiece support 120 through the first moving mechanism 140. In addition, the spindle 110, the tool magazine 130, and the spindle support 150 are also preferably supported by the base 190. In this way, the above-mentioned components of the machine tool 100 are installed on the base 190 as a whole in the housing of the machine tool 100 not shown. Furthermore, the machine tool 100 is automatically controlled by a control system not shown, thereby constituting a device that can be used for automated processing. As an example, the machine tool 100 is, for example, a numerical control (NC) device or a computer numerical control (CNC) device, so that the aforementioned processing steps and tool changing steps can be performed in an automated manner. Although the base 190 is used as the base of the machine tool 100 to support the aforementioned components (workpiece support 120, etc.) as an example, the use of the base 190 may be omitted. In addition, although the machine tool 100 is used as an automated device having a housing and a control system as an example, an implementation method in which the machine tool 100 is operated by a user is not excluded. The present invention does not limit the specific structure of the machine tool 100 and the implementation method for performing the aforementioned processing steps and tool changing steps, which may also be adjusted according to needs.

[0081] As described above, in this embodiment, when the first direction is the front-rear direction Y, the tool magazine 130 is arranged behind the workpiece support 120, and the spindle support 150 is also arranged behind the workpiece support 120. When the spindle support 150 and the tool magazine 130 are both arranged behind the workpiece support 120, in the second direction (left-right direction X) orthogonal to the first direction (front-rear direction Y), the tool magazine 130 is movable (corresponding to the position overlapping at least a portion of the spindle support 150) Figure 1 That is, when the machine tool 100 is viewed from the side (i.e., viewed from the second direction), the moving range of the tool magazine 130 passes through at least a portion of the spindle support 150. In this way, the workpiece support 120 is moved by the first moving mechanism 140, so that the tool magazine 130 disposed on the workpiece support 120 also moves synchronously, and the moving range of the tool magazine 130 is set to overlap with at least a portion of the spindle support 150 when viewed from the side, thereby not only ensuring the moving range of the tool magazine 130, but also reducing the size of the machine tool 100 and miniaturizing the structure.

[0082] As an example, in this embodiment, if Figures 1 to 3As shown, the spindle support part 150 includes two pillars 152A and 152B spaced apart in the second direction (for example, the left-right direction X). For example, the two pillars 152A and 152B are spaced apart in the second direction (left-right direction X) on the base 190 and extend in the up-down direction Z to support the spindle 110 on the upper side of the base 190. The second moving mechanism 170 and the third moving mechanism 180 for making the spindle 110 movable can also be supported on the upper side of the base 190 by the two pillars 152A and 152B, but it is not limited to this. Furthermore, the interval between the two pillars 152A and 152B in the second direction (left-right direction X) is greater than the size of the tool magazine 130 in the second direction (left-right direction X). During the movement of the tool magazine 130, the tool magazine 130 can pass between the two pillars 152A and 152B, so that the tool magazine 130 overlaps at least a part of the two pillars 152A and 152B when viewed from the side. That is, the movement range of the tool magazine 130 in the first direction (front-rear direction Y) passes between the two pillars 152A and 152B. In this way, the movement range of the tool magazine 130 can be ensured, and the size of the machine tool 100 can be reduced to make the structure compact.

[0083] Through the above arrangement, when the workpiece support 120 is located at the processing position (ie, the workpiece support 120 corresponds to the position of the spindle 110), as shown in FIG. Figure 1 As shown, the tool magazine 130 moves to the rear in the first direction (front-to-back direction Y), and overlaps with at least a portion of the spindle support portion 150 in the second direction (left-right direction X). Furthermore, in a third direction (up-down direction Z) orthogonal to the first direction (front-to-back direction Y) and the second direction (left-right direction X), the tool magazine 130 overlaps with at least a portion of the second moving mechanism 170. That is, the tool magazine 130 moves to the space between the two pillars 152A and 152B serving as the spindle support portion 150 and the second moving mechanism 170 supported by the spindle support portion 150, so that the tool magazine 130 overlaps with at least a portion of the spindle support portion 150 when viewed from the second direction (left-right direction X), and overlaps with at least a portion of the second moving mechanism 170 when viewed from the third direction (up-down direction Z). In contrast, when the workpiece support portion 120 is located at the tool changing position (that is, when the tool magazine 130 corresponds to the position of the spindle 110), as shown in FIG. Figure 2As shown, the tool magazine 130 moves forward in the first direction (front-rear direction Y), and does not overlap with the spindle support 150 in the second direction (left-right direction X). In this way, when the workpiece support 120 is in the processing position, the tool magazine 130 can be away from the spindle 110 for processing while being close to the spindle support 150, and when the workpiece support 120 is in the tool changing position, the tool magazine 130 can be close to the spindle 110 for tool changing while being away from the spindle support 150. Although two pillars 152A and 152B are used as examples of the spindle support 150, the present invention is not limited thereto as long as the spindle support 150 can support the spindle 110 and can overlap at least a part of the moving range of the tool magazine 130.

[0084] For example, in Figure 4 In the illustrated variation, the machine tool 100A has a substantially similar structure to the aforementioned machine tool 100, with the main difference being that the spindle support 150A is different from the aforementioned spindle support 150. Figure 4 In a modified example, the spindle support portion 150A includes a first portion 154 disposed in the second direction (left-right direction X) relative to the tool magazine 130, and a second portion 156 disposed in the first direction (front-rear direction Y) relative to the tool magazine 130. For example, the first portion 154 is disposed on the base 190 and is located on one side (e.g., the left side or the right side) of the second direction (left-right direction X) relative to the tool magazine 130, and extends in the up-down direction Z. The second portion 156 is disposed on the base 190, connected to the first portion 154, and is located on one side (e.g., the rear side) of the first direction (front-rear direction Y) relative to the tool magazine 130, and extends in the left-right direction X. The spindle 110 is supported on the upper side of the base 190 by the first portion 154 and the second portion 156. The second moving mechanism 170 and the third moving mechanism 180 for making the spindle 110 movable may also be supported on the upper side of the base 190 by the first portion 154 and the second portion 156, but is not limited thereto. In the second direction (left-right direction X), the tool magazine 130 is movable in a position overlapping with at least a portion of the first portion 154. That is, the movable range of the tool magazine 130 in the first direction (front-back direction Y) is such that the tool magazine 130 overlaps with at least a portion of the first portion 154 when viewed from the side. In this way, the movable range of the tool magazine 130 can be ensured, and the size of the machine tool 100A can be reduced to make the structure compact.

[0085] Similarly, through the above arrangement, when the workpiece support 120 is located at the machining position (i.e., when the workpiece support 120 corresponds to the position of the spindle 110), the tool magazine 130 moves to the rear in the first direction (front-rear direction Y) and overlaps at least a portion of the spindle support 150A in the second direction (left-right direction X). On the other hand, when the workpiece support 120 is located at the tool changing position (i.e., when the tool magazine 130 corresponds to the position of the spindle 110), the tool magazine 130 moves to the front in the first direction (front-rear direction Y) and does not overlap with the spindle support 150A in the second direction (left-right direction X). In this way, when the workpiece support 120 is located at the machining position, the tool magazine 130 can be away from the spindle 110 for machining while being close to the spindle support 150A, and when the workpiece support 120 is located at the tool changing position, the tool magazine 130 can be close to the spindle 110 for tool changing while being away from the spindle support 150A. Although the example in which a pair of first parts 154 are provided on the left and right sides and the second part 156 connects the pair of first parts 154 is used here (for example, it is configured as a frame structure or a wall structure with a notch in the center), it is also possible to only have one first part 154 and one second part 156 (for example, it is configured as an L-shaped structure). As long as the spindle support part 150A can support the spindle 110 and can overlap at least a part of the moving range of the tool magazine 130, the present invention does not limit the specific structure of the spindle support part 150A, which can be adjusted according to needs.

[0086] From the above description, it can be known that in this embodiment, when the workpiece support 120 drives the tool magazine 130 to move, when viewed from the side, the tool magazine 130 can overlap at least a part of the spindle support 150 (or the spindle support 150A), so that the movement range of the tool magazine 130 passes through the spindle support 150 (or the spindle support 150A), thereby ensuring the movement range of the tool magazine and reducing the size of the machine tool 100 (or the machine tool 100A) to make the structure miniaturized. As an example, in FIG. 5A to FIG. 5J FIG. 1 shows an operation diagram of the machine tool 100 removing the tool 20 from the spindle 110 and installing the tool 20 in the tool magazine 130 to the spindle 110 during the tool changing process. Figure 5A In the process, the machine tool 100 completes the processing step, and the third moving mechanism 180 moves the spindle 110 upward in the vertical direction Z as the third direction, so that the spindle 110 leaves the workpiece support 120. Figure 5BIn the process, the workpiece support 120 is moved forward in the front-rear direction Y as the first direction by the first moving mechanism 140, and the tool magazine 130 located behind the workpiece support 120 is moved forward toward the predetermined position and moved to the position directly below the spindle 110, so as to facilitate the tool changing process. When the workpiece support 120 is located at the tool changing position (that is, when the tool magazine 130 corresponds to the position of the spindle 110), the tool magazine 130 does not overlap with the spindle support 150 in the second direction (left-right direction X). At the same time, during the movement of the tool magazine 130, the magazine cover 134 shifts from the closed state to the open state, and the tool 20 supported on the tool holder 132 is exposed.

[0087] Then, in Figure 5C In the embodiment, the spindle 110 is moved downward in the vertical direction Z as the third direction by the third moving mechanism 180 to approach the tool holder 132, so that the tool 20 mounted on the spindle 110 is located in front of the tool holder 132. The tool 20 mounted on the spindle 110 and the tool holder 132 are located at a position in the front-rear direction Y. Figure 5B Then, Figure 5D In the embodiment, the workpiece support 120 is moved forward in the front-rear direction Y as the first direction by the first moving mechanism 140, so that the tool 20 mounted on the spindle 110 enters the front opening of the clamp 132a provided on the tool handle 132 from the front side of the tool handle 132, so that the tool 20 is supported on the tool handle 132 by being clamped by the clamp 132a. Figure 5E In the process, the spindle 110 is released from the mounted tool 20, and the spindle 110 is moved upward in the vertical direction Z as the third direction by the third moving mechanism 180 to leave the tool holder 132, so that the released tool 20 is removed from the spindle 110 and remains on the tool holder 132. Fig. 5F In the process, the second moving mechanism 170 moves the spindle 110 in the left-right direction X as the second direction toward the position of the next tool 20, so that the spindle 110 is located directly above the next tool 20. Figure 5G In the process, the spindle 110 is moved downward in the up-down direction Z as the third direction by the third moving mechanism 180 to approach the tool holder 132 , and the spindle 110 is coupled to the next tool 20 .

[0088] Then, in Figure 5H In the process, the workpiece support 120 is moved to the rear in the front-rear direction Y as the first direction by the first moving mechanism 140, so that the tool 20 mounted on the spindle 110 is moved away from the front opening of the fixture 132a provided on the tool holder 132, so that the tool 20 is released from the tool holder 132 and removed from the tool holder 132. Fig.5IIn the process, the spindle 110 is moved upward in the vertical direction Z as the third direction by the third moving mechanism 180, so that the spindle 110 is separated from the tool magazine 130. Figure 5J In the process, the machine tool 100 completes the tool changing process, and the workpiece support 120 is moved to the rear of the front-rear direction Y as the first direction by the first moving mechanism 140, and the workpiece support 120 is moved to the processing position and is located directly below the spindle 110, so as to facilitate the processing process. When the workpiece support 120 is located at the processing position (that is, when the workpiece support 120 corresponds to the position of the spindle 110), the tool magazine 130 overlaps with at least a portion of the spindle support 150 in the second direction (left-right direction X). At the same time, during the movement of the tool magazine 130, the magazine cover 134 shifts from the open state to the closed state, and covers the tool 20 supported on the tool holder 132.

[0089] Furthermore, in this embodiment, if Figure 6 As shown, the machine tool 100 can also move the tool magazine 130 further away from the processing area (for example, to the rear) during the processing step, so that the workpiece support 120 can retain a larger processing area in the first direction. In this case, since the moving range of the tool magazine 130 can pass through the spindle support 150 (or the spindle support 150A), even if the tool magazine 130 is set at a position away from the workpiece support 120 to increase the moving range of the tool magazine 130, it is not necessary to increase the size of the machine tool 100 in the first direction. FIG. 5A to FIG. 5J and Figure 6 The operation flow shown is also applicable to the machine tool 100A, and will not be repeated here. However, the above content is only one example of the tool changing process of the machine tool 100 of the present invention, and each step can be adjusted according to the requirements (for example, the specific structure and relative position of each component of the machine tool 100, etc.), and the present invention is not limited to this.

[0090] In summary, in the machine tool of the present invention, the tool magazine is arranged on the workpiece support portion, the tool magazine and the workpiece support portion are moved synchronously in the first direction, and the moving range of the tool magazine is arranged to overlap with at least a part of the spindle support portion when viewed from the side. Accordingly, the machine tool of the present invention can ensure the moving range of the tool magazine, and can reduce the size of the machine tool and make the structure miniaturized.
