Description

[0001] This application relates to the field of CNC machine tool technology, and in particular to a tool magazine and a multi-station multi-axis composite machine tool. Background Technology

[0002] With the emergence and widespread application of four-axis and five-axis machine tools in China, the productivity level of machining in the domestic processing and manufacturing industry has been greatly improved. Based on the existing production efficiency, multi-station multi-axis composite machine tools have been developed to improve production efficiency and meet customer needs. For example, CN117655917A provides a four-station five-axis composite machine tool.

[0003] However, the multi-station, multi-axis composite machine tools provided by related technologies have limited tool magazine capacity and large overall size, requiring a large operating space inside the machine. This makes it impossible to design a compact overall layout, resulting in a large machine size. The inconveniences of large machine tools are obvious, such as high transportation and installation costs, low space utilization efficiency in manufacturing and assembly workshops due to their large footprint, and high rental costs for production and processing sites.

[0004] In addition, the cutter head of common composite machine tools is directly exposed in the machining space. The corrosion of machining debris, dust, machining reagents and other substances will shorten the service life of the cutter head, increase the probability of failure, and increase the maintenance cost.

[0005] Therefore, multi-station, multi-axis composite machine tools urgently need a compact tool magazine design to solve the above problems. Summary of the Invention

[0006] To address the aforementioned issues, this application provides a tool magazine and a multi-station, multi-axis composite machine tool.

[0007] In a first aspect, embodiments of this application provide a tool magazine, comprising: a rotating tool disc for loading tools; a tool disc drive assembly for driving the rotating tool disc to rotate around a rotating axis, the rotating axis overlapping with the axial center line of the rotating tool disc; a tool disc motion shaft assembly for driving the tool disc drive assembly to reciprocate toward or away from a first direction, while simultaneously driving the rotating tool disc to move, the first direction being parallel to the length extension direction of the tool disc motion shaft assembly; and a protective assembly having a receiving space, wherein the rotating tool disc and the tool disc drive assembly are received in the receiving space, and the tool disc motion shaft assembly is fixedly connected to the inner wall of the receiving space; wherein the receiving space is connected to an external space through opposing first and second openings, and the tool disc motion shaft assembly extends out through the second opening.

[0009] In some embodiments, the protective assembly further includes a linkage mechanism fixedly connected to the end wall, the linkage mechanism including a first driving member, a first connecting member, and a rod; one end of the rod is fixedly connected to the baffle, and the opposite end is fixedly connected to the first driving member through the first connecting member; the first driving member drives the rod to push or pull the baffle to rotate.

[0010] In some embodiments, the rod body includes a first rod body and a second rod body, one end of the first rod body and one end of the second rod body are respectively fixedly connected to the baffle, and the other end of the first rod body and the other end of the second rod body are simultaneously pivotally connected to the first connector.

[0011] In some embodiments, the rod has different first and second states. In the first state, the first rod and the second rod cooperate to form a V-shaped structure; in the second state, the first rod and the second rod cooperate to form a T-shaped structure.

[0012] In some embodiments, the end wall is provided with a limiting member, which is disposed near the first opening to limit the rotation angle of the baffle.

[0013] In some embodiments, the cutter head drive assembly includes an indexer and a second drive member with meshing transmission, wherein the power provided by the second drive member is converted into intermittent output motion through the indexer.

[0014] In some embodiments, the rotary cutter head includes a cutter head body, a rotary connector, and chucks.

[0015] Secondly, embodiments of this application also provide a multi-station, multi-axis composite machine tool, which includes a machine tool base, a machine tool drive group, a workpiece clamping group, a machining axis group, and a tool magazine, wherein: the machine tool drive group is fixed to the base module; the workpiece clamping group is fixed to the drive module and is used to clamp the workpiece to be processed; the machining axis group is fixed to the machine tool drive group and is used to process the workpiece to be processed; the tool magazine is fixed to the base module, and the tool magazine is any of the tool magazines described above.

[0016] In some embodiments, the machine tool base includes a gantry frame, the columns of the gantry frame are provided with bosses, and the tool magazine is fixedly installed on the bosses by means of the tool magazine fixing blocks.

[0017] Compared with related technologies, the tool magazine provided in this application selects the tool to be replaced through the self-rotation of the tool head.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only one embodiment of this application, and not all embodiments.

They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0029] Please refer to the following: Figure 1 and Figure 2 , Figure 1 Parts (a) and (b) respectively show the three-dimensional structure of the tool magazine provided in one embodiment of this application from different perspectives. Figure 2 Show Figure 1 The three-dimensional structure of the tool magazine shown is for illustrative purposes only. Figure 2 The end wall is not shown. The tool magazine 1 provided in this embodiment is used to load tools 2 to cooperate with multi-station multi-axis composite machine tools for batch tool changing programs. The tools 2 can be milling cutters, engraving cutters, or other tools used for CNC machine tools, and are specifically used for engraving, milling, or engraving on the workpiece to be processed.

[0030] The tool magazine 1 includes a protective assembly 11, a rotating tool disc 13, a tool disc drive assembly 15, and a tool disc motion shaft assembly 17. The protective assembly 11 has a receiving space 12, which is connected to the external space through a first opening 121 and a second opening 123. The tool disc motion shaft assembly 17 is fixedly connected to the inner wall of the receiving space 12, partially contained within the receiving space 12, and extends out through the second opening 123. The rotating tool disc 13 and the tool disc drive assembly 15 are contained within the receiving space 12, and the tool disc drive assembly 15 is fixedly connected to the tool disc motion shaft assembly 17 and the rotating tool disc 13. The tool disc drive assembly 15 drives the rotating tool disc 13 to rotate around the rotation axis A by a certain angle, and the tool disc motion shaft assembly 17 drives the tool disc drive assembly 15 to reciprocate in or away from the first direction W, thereby driving the rotating tool disc 13 to reciprocate in or away from the first direction W.

[0031] It is understood that the rotation axis A is a straight line overlapping the axial center line of the rotating cutter head 13, and the first direction W is a direction parallel to the length extension direction of the cutter head motion axis assembly 17. The rotation axis A and the first direction W in the accompanying drawings are exemplary drawings for illustrative purposes; in other embodiments, the first direction may point in the opposite direction.

[0032] Specifically, the protective component 11 includes a mounting base 111, an end wall 113, a baffle 115, and a protective cover 117. The mounting base 111 is fixedly connected to the end wall 113, and the protective cover 117 is fixedly connected to the end wall 113. The mounting base 111, the protective cover 117, and the end wall 113 cooperate to form the receiving space 12, and are fixedly connected, for example, by welding or riveting. The baffle 115 is provided corresponding to the first opening 121, and includes a first baffle and a second baffle arranged in parallel. The first baffle is hinged to the mounting base 111, and the second baffle is hinged to the end wall 113. In this embodiment, the hinge connection is achieved through a hinge connector 1151. The tool magazine 1 realizes the opening or closing process by rotating the first baffle relative to the mounting base 111 and rotating the second baffle relative to the end wall 113.

[0033] The mounting base 111 is provided with several fixing blocks 1111. The tool magazine 1 is fixedly installed on the multi-axis composite machine tool at the workstation through the fixing blocks 1111, for example, by welding or riveting.

[0034] Understandably, this is for the sake of ease of demonstration and understanding. Figure 1 One of the guards 117 was removed. In fact, the number of guards 117 corresponds to the guide rail arrangement of the cutter head motion axis assembly 17, which is used to protect the guide rail.

[0035] To controllably maintain the open / closed state of the tool magazine 1, the protective assembly 11 further includes a linkage mechanism 119, which is disposed opposite to the end wall 113. Please refer to [reference needed]. Figure 2 and Figure 3 , Figure 3 for Figure 1 The diagram shown is a partial 3D structural representation of the tool magazine from another perspective, for ease of illustration. Figure 2 The end wall portion is not shown.

[0036] The linkage mechanism 119 includes a rod 1191, a first connecting member 1193, a second connecting member 1195, and a first driving member 1197. One end of the rod 1191 is fixedly connected to the baffle 115, and the other end is pivotally connected to the first connecting member 1193. The rod 1191 is fixedly connected to the first driving member 1197 via the first connecting member 1193, and the first driving member 1197 is fixedly connected to the end wall 113 via the second connecting member 1195, for example, by welding or riveting. The first driving member 1197 drives the rod 1191 to reciprocate relative to the end wall 113 in the first direction W, either towards or away from the first direction, so that the rod 1191 pushes or pulls the baffle 115 to rotate, thereby opening or closing the tool magazine 1.

[0037] The end wall 113 is provided with a third opening 125 corresponding to the first driving member 1197, and one end of the first driving member 1197 extends out through the third opening 125.

[0038] The rod 1191 has different first and second states, and includes a first rod and a second rod. The closed state of the tool magazine 1 corresponds to the first state. In the first state, one end of the first rod and one end of the second rod are fixedly connected to the first baffle and the second baffle, respectively, for example, by welding or riveting. Conversely, the other ends of the first rod and the second rod are simultaneously pivotally connected to a point on the first connector 1193, thereby forming a herringbone structure with the first rod and the second rod.

[0039] Driven by the first driving member 1197, the rod 1191 changes from the first state to the second state, and the opening state of the tool magazine 1 corresponds to the second state. The first driving member 1197 drives the first rod and the second rod, thereby pushing the first baffle and the second baffle to rotate. When the rotation reaches a critical point within a preset range, the rod is in the second state, and the first rod and the second rod cooperate to form a T-structure.

[0040] Near the first opening 121, limiting members 1131 are provided on opposite sides of the end wall 113. The limiting members 1131 can be installed on the end wall 113 by snap-fit ​​or adhesive bonding. The baffle 115 is pulled and rotated by the linkage mechanism 119, and after rotating to a certain angle, it is obstructed by the limiting members 1131. The limiting members 1131 can prevent the baffle 115 from rotating beyond its limit and causing damage to other components within the receiving space 12. It is understood that in other embodiments, the limiting members 1131 can also be provided relative to the end wall 113 and the mounting base 111; simply placing them near the first opening 121 is sufficient to achieve the limiting function for the baffle 115.

[0041] In this embodiment, the first drive component 1197 can be an industrial mini cylinder, the first connector 1193 and the second connector 1195 are both sheet metal connecting plates with punching, and the first connector 1193 can be an L-shaped connecting plate.

[0042] Please refer to the following: Figure 3 and Figure 4 , Figure 4 Parts (a) and (b) show the assembly relationship between the rotary cutter head 13, the cutter head drive assembly 15, and the cutter head motion shaft assembly 17 from different perspectives. The cutter head motion shaft assemblies 17 are spaced apart on the mounting base 111, and the spacing between the cutter head motion shaft assemblies 17 is adapted to the length of the rotary cutter head 13, so that the two opposite ends of the rotary cutter head 13 are fixedly connected to the cutter head motion shaft assemblies 17 through the cutter head drive assembly 15.

[0043] The cutter head motion axis assembly 17 includes a third connector 171, a slider 173, a guide rail 175, and an electric cylinder device 177. The guide rail 175 is arranged parallel to the first direction, and the guide rail 175 is configured to cooperate with the slider 173. The slider 173 is fixedly connected to the mounting base 111, and the third connector 171 is fixedly connected to the guide rail 175. The electric cylinder device 177 drives the third connector 171 to reciprocate along the guide rail 175, either towards or away from the first direction.

[0044] It should be noted that the electric cylinder device 177 is a conventional electric cylinder device, and its specific structure and working principle are well known to those skilled in the art, so it is briefly introduced here.

[0045] The electric cylinder device 177 includes an electric cylinder body 1771, an electric cylinder mounting plate 1773, sensors 1775, and a push plate 1777. The electric cylinder mounting plate 1773 includes a first mounting part 17731 and a second mounting part 17733 that cooperate with each other. The output end of the electric cylinder body 1771 is horizontally fixed to the mounting base 111 through the first mounting part 17731 and fixedly connected to the push plate 1777 through the second mounting part 17733. Multiple sensors 1775 are arranged in a straight line and engaged with the push plate 1777. The sensors 1775 communicate with the electric cylinder body 1771. Two opposite ends of the push plate 1777 are fixedly connected to a third connecting member 171. The electric cylinder body 1771 drives the push plate 1777 to move, thereby causing the third connecting member 171 to reciprocate along the guide rail 175 towards or away from the first direction.

[0046] The cutter head drive assembly 15 includes an indexer 151 and a second drive member 153 for meshing transmission. The power provided by the second drive member 153 is converted into intermittent output motion through the indexer 151, thereby causing the indexer 151 to drive the rotating cutter head 13 to rotate intermittently around the rotation axis A at a certain angle. The indexer 151 is fixedly connected to the third connecting member 171, for example, by welding or riveting. In this embodiment, the indexer 151 can be an arc-shaped cam divider or a flat cam divider. In this embodiment, the second drive member 153 can be a servo motor or a permanent magnet motor.

[0047] Please refer to the following: Figure 5 and Figure 6 , Figure 5 for Figure 4 The diagram shown illustrates the assembly relationship between the rotary cutter head and the cutter head drive assembly. Figure 6 for Figure 4 The schematic diagram of the three-dimensional structure of the rotating cutter head shown is for illustrative purposes only. Figure 5 The rotating cutter head in the middle is loaded with cutting tools.

[0048] The rotating cutter head 13 includes a cutter head body 131, a rotating connector 133, and chucks 135. The cutter head body 131 is a cylindrical structure symmetrical about a rotation axis A, and its two opposite ends along its length are fixedly connected to the indexer 151 through the rotating connector 133. The cutter head body 131 has a first loading part 1311 and a second loading part 1313 of the same specifications, which are arranged perpendicularly to each other. The chucks 135 are arranged in a straight line and fixedly installed on the first loading part 1311 and the second loading part 1313, for example, by welding or riveting. The chucks 135 engage and fix the cutter 2 to achieve the loading of the cutter 2.

[0049] The following provides an exemplary multi-station, multi-axis composite machine tool 3 equipped with the tool magazine 1. Implementable machine tool designs have been provided in related technologies, and their working principles are understandable to those skilled in the art. Therefore, this application focuses on the assembly relationship between the tool magazine 1 and the multi-station, multi-axis composite machine tool 3. Of course, those skilled in the art can also apply the tool magazine 1 to multi-station, multi-axis composite machine tools with other layout designs.

[0050] Please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a three-dimensional structural diagram of a multi-station, multi-axis composite machine tool provided in one embodiment of this application, viewed from one perspective. Figure 8 for Figure 7 The diagram shows a three-dimensional structure of a multi-station, multi-axis composite machine tool from another perspective.

[0051] The multi-station, multi-axis composite machine tool 3 includes a machine tool base 31, a machine tool drive assembly 33, a workpiece clamping assembly 35, a machining axis assembly 37, and a tool magazine 11. The machine tool drive assembly 33 and the tool magazine 11 are fixed to the machine tool base 31, and the workpiece clamping assembly and the machining axis assembly 37 are fixed to the machine tool drive assembly 33. The workpiece clamping assembly 35 clamps and fixes the workpiece to be processed, the machine tool drive assembly 33 drives the machining axis assembly 37 to process the workpiece, and the tool magazine 1 cooperates with the machining axis assembly 37 to change the cutting tools 2, so that the workpiece can be engraved, milled, or patterned in various ways.

[0052] The machine tool base 31 includes a worktable 311, a gantry frame 313, and a recovery tray 315. The worktable 311 has a box-shaped structure and is supported and fixed to a horizontal ground by several feet. The gantry frame 313 and the recovery tray 315 are located at the top of the worktable 311 and are arranged adjacent to each other. The recovery tray 315 has a funnel-shaped sunken structure, that is, it sunk from the top of the worktable 311 and extended into the interior of the worktable 311 to form a funnel shape. One side of the gantry frame 313 is a working surface, which faces the recovery tray 315. The working surface and the area above the recovery tray 315 form the processing space 317 of the multi-station multi-axis composite machine tool 3. The processing of the workpiece by the multi-station multi-axis composite machine tool 3 is completed within the processing space 317. When the workpiece is processed, the precious metal shavings, dust and processing waste liquid generated will fall naturally into the recycling tray 315 and slide down the inner side wall of the recycling tray 315 to the bottom of the recycling tray 315 for collection and recycling.

[0053] The machine tool drive group 33 is divided into two perpendicular X-axis groups 331, Y-axis groups 333, and Z-axis groups 335. The X-axis groups 331 are horizontally positioned on the crossbeam portion of the working surface; the Z-axis groups 335 are vertically positioned on top of the X-axis groups 331; the Y-axis groups 333 are horizontally positioned on the top of the worktable 311 and are perpendicular to the gantry frame 313. The X-axis groups 331, Y-axis groups 333, and Z-axis groups 335 work together to form a complete XYZ drive axis system. The multi-station multi-axis composite machine tool 3 uses only one XZY drive axis system to simultaneously drive the machining axis group 37 for machining. This results in a compact internal layout and a small footprint. Furthermore, the number of logical relationships between components is reduced, leading to fewer potential failure points and improved structural reliability of the multi-station multi-axis composite machine tool 3.

[0054] The machining axis assembly 37 includes at least two independent electric spindles 371, which are arranged side by side and fixedly mounted on the fixing plate of the Z-axis assembly 335. In this embodiment, the number of electric spindles 371 is four.

[0055] The workpiece clamping assembly 35 includes a turntable 351, an A-axis assembly 353, and a C-axis assembly 355. The turntable 351 is fixedly connected to the slider of the Y-axis assembly 333 by welding or riveting. The A-axis assembly 353 is arranged parallel to the X-axis assembly 331, and the two opposite ends of the A-axis assembly 353 are fixedly connected to the turntable 351. The C-axis assembly 355 is arranged linearly along the axial direction of the A-axis assembly 353 and is parallel to the Z-axis assembly 335. The C-axis assembly 355 can be a pneumatic gripper, a vacuum adsorption device, or a manual clamping fixture, etc., capable of clamping and fixing the workpiece to be processed. The turntable 351 drives the A-axis assembly 353 to drive the C-axis assembly 355, rotating around the center line of the A-axis assembly 353 as the rotation axis.

[0056] The uprights on both sides of the gantry frame 313 are provided with opposing bosses 3131, which extend towards each other. The tool magazine 1 is mounted on the bosses 3131 and fixed by the fixing block 1111, for example, by welding or riveting. The rotation axis A of the rotating cutter head 13 is parallel to the crossbeam portion of the gantry frame 313.

[0057] During the tool change procedure, the tool magazine 1, via the linkage mechanism 119, pushes the baffle 115 to rotate, exposing the first opening 121, thus opening the tool magazine 1. The tool turret motion axis assembly 17 drives the tool turret drive assembly 15 and the rotary tool turret 13 to move, passing through the first opening 121 into the machining space 317. The tool turret drive assembly 15 drives the rotary tool turret 13 to rotate, rotating the tool to be replaced to the tool change position on the electric spindle 371.

[0058] After the tool change is completed, the tool head motion axis assembly 17 drives the tool head drive assembly 15 and the rotating tool head 13 to exit the machining space 317 and return to the receiving space 12 through the first opening 121. The linkage mechanism 119 retracts, thereby driving the baffle 115 to rotate. The limiting member 1131 restricts the rotation range of the baffle 115, and the tool magazine 1 is in a closed state.

[0059] In summary, the tool magazine provided in this application selects the tool to be replaced through the rotation of the tool head. The tool magazine itself requires little operating space, and combined with the tool changing program of the composite machine tool, it can simultaneously reduce the operating space required for the entire machine. This makes the multi-station, multi-axis composite machine tool more compact in overall size while maintaining the same functionality, significantly reducing the floor space required. This not only increases the efficiency of space utilization in the manufacturing and assembly workshop but also saves on rental costs. At the same time, the tool magazine is equipped with protective components to protect the rotating tool head from corrosion by machining debris, dust, machining reagents, and other substances, reducing the failure rate.

[0060] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
