Description

Technical Field

[0001] This application relates to a processing machine, and particularly to a tool magazine system of a processing machine. Background Art

[0002] In order to improve the processing efficiency, existing processing machines are often equipped with a tool changing arm and a tool magazine, which are convenient for exchanging the tool shanks on the spindle and the tool shanks in the tool magazine with the tool changing arm. However, this tool magazine occupies a large space, has a complex structure and is not suitable for multi-spindle processing machines.

[0003] Moreover, the tool magazines of multi-axis processing machines are usually arranged on the back or side of the machine tool, resulting in disadvantages such as long tool change stroke, long tool change time, and few tool numbers that can be placed in the tool magazine.

[0004] For example, CN105873720A discloses a tool magazine that is independently arranged on the side of the workbench, distinguishing a frame area and an Automatic Tool Changer (ATC) area. However, this tool magazine occupies a large space and has a complex structure.

[0005] Therefore, in view of the foregoing technical problems, this application provides a tool magazine system for a processing machine, which can change the number of tool shanks in batches according to the number of spindles of the processing machine. Summary of the Utility Model

[0006] The purpose of this application is to solve the problems of low tool change efficiency of the tool magazine of the processing machine and the space occupied by the tool magazine, so as to provide a tool magazine system for the processing machine, simplify the actions required for tool change exchange, reduce the tool change time, and improve the tool change efficiency.

[0007] To achieve the above object, an embodiment of this application provides a tool magazine system for a processing machine, which is arranged on the processing machine. The processing machine has a work platform and multiple spindles. The tool magazine system of the processing machine includes a tool storage device and a tool exchange device. The tool storage device is located in front of the spindle. The tool storage device has a plurality of tool carrying units arranged in parallel along the Y-axis. Each tool carrying unit has a lifting frame and a tool clamping seat positioned on the lifting frame. The lifting frame can be lifted and displaced along the Z-axis and switched between a tool storage position and a tool change preparation position; the tool exchange device can make the tool clamping seat disengage from and return to the lifting frame at the tool change preparation position, so as to drive the tool clamping seat to shift along the Y-axis to the tool change position for the spindle to remove or replace the tool shank from the tool clamping seat.

[0008] In another embodiment, the tool storage device is located above the work platform and has a driving unit. The driving unit has a driving source and a connected driving shaft, and a plurality of Z-axis lifting units are provided at the tool storage position. The Z-axis lifting units are respectively connected to the driving shaft and the lifting frame.

[0009] In another embodiment, each of the Z-axis lifting units includes a driving gear, a clutch member, and a rack. The driving gear is coaxially connected to the clutch member by a drive shaft. The driving gear meshes with the rack, and the rack is connected to the lifting frame. The clutch member is capable of performing a clutch action relative to the driving gear. When the clutch member is connected to the driving gear and can be driven by the drive shaft for transmission, the driving gear drives the rack to displace along the Z-axis, causing the lifting frame to displace to the tool change preparation position.

[0010] In another embodiment, the tool storage device has a fixed seat provided on the processing machine. The Z-axis lifting unit and the drive shaft are provided on the fixed seat; the rack penetrates through the fixed seat; the fixed seat is provided with a limiting unit on one side of each Z-axis lifting unit for selectively limiting the height of the rack, so that the lifting frame is held at the tool storage position or the tool change preparation position.

[0011] In another embodiment, the limiting unit includes a limiting rod and a pneumatic cylinder for driving the limiting rod to act. A plurality of limiting holes are provided on one side of the rack for the opposite limiting rods to extend into and insert, for limiting the height position of the rack; the Z-axis lifting unit is provided with guide rods on both sides of the driving gear. The guide rods slidably penetrate through the fixed seat and are connected to the opposite lifting frames.

[0012] In another embodiment, side rods are provided on both sides of the lifting frame. The tool clamping seat and the side rods have corresponding positioning blocks. The positioning blocks can slide relative to the side rods along the Y-axis; a positioning member is provided between the positioning blocks and the side rods. The positioning member can move relative to the Z-axis to cause the positioning blocks and the side rods to have a positioning relationship.

[0013] In another embodiment, the side rod has a transverse groove for a part of the positioning block to slide and connect; the bottom of the positioning block has a connection hole. The tool exchange device includes a sliding seat and a pushing member. The sliding seat can displace along the Y-axis. The pushing member is provided on the sliding seat and can displace relative to the sliding seat along the X-axis. Corresponding connection columns are provided on both sides of the pushing member for the positioning blocks. When the lifting frame is displaced to the tool change preparation position, the connection hole and the connection columns are engaged and positioned with each other.

[0014] In another embodiment, the processing machine has a machine base. A working platform is provided on the machine base. The machine base is provided with a column. The main shaft can move along the Z-axis and is provided on the column. The processing machine is provided with a frame on the opposite side of the column; the tool exchange device further includes a Y-axis driving unit and an X-axis driving unit. The Y-axis driving unit is provided between the column and the frame for driving the sliding seat to displace along the Y-axis. The X-axis driving unit is provided between the sliding seat and the pushing member for driving the pushing member to displace along the X-axis.

[0015] In another embodiment, the tool changing device is arranged on one side of the working platform, and the working platform can be displaced along the X-axis and the Y-axis.

[0016] Thereby, before the tool holder for storing the tool handle is moved to the tool changing position, it only makes displacements in the Z-axis and Y-axis directions, thereby simplifying the actions required for tool holder exchange, reducing the time for replacing the tool holder, and improving the tool changing efficiency.

[0017] In addition, the tool storage device is located in front of the main shaft and above the working platform, which can reduce the space occupied by the machine tool.

[0018] Multiple tool carrying units of the tool storage device can store multiple sets of tool handles simultaneously for applications that require multiple tool numbers for processing.

[0031] The exemplary embodiments of the present application will be described in detail below with reference to the accompanying drawings, and it is not intended to limit the technical principles of the present application to the specifically disclosed embodiments. The scope of the present application is only limited by the scope of the patent application, covering alternatives, modifications, and equivalents.

[0032] Those skilled in the relevant technical fields may think of and make various modifications and further improvements, including any other applications of the technical features described herein and the principles of the present application. These modifications and applications should be regarded as within the scope of the present application. In addition, for the sake of readability, some parts of the components are omitted in some drawings, or are depicted in the form of imaginary lines, etc.

[0033] Please refer to Figures 1 to 10 As shown, a tool magazine system 100 of the present application is provided on a processing machine 1, and the processing machine 1 has a work platform 2 and a main shaft 3. Among them, the processing machine 1 can be a single-axis processing machine or a multi-axis processing machine. If it is a multi-axis processing machine, it has multiple main shafts 3. The work platform 2 is provided on the machine base 4 of the processing machine 1, and the machine base 4 is provided with a column 5. The main shaft 3 can move along the Z-axis and is provided on the column 5. The processing machine 1 is provided with a frame 6 on the opposite side of the column 5. The tool magazine system 100 of the processing machine includes a tool storage device 7 and a tool changing device 8.

[0034] The tool storage device 7 is located in front of the main shaft 3 and above the machine base 4 and the work platform 2. The tool storage device 7 has a plurality of tool carrying units 10 arranged in parallel along the Y-axis. Each tool carrying unit 10 has a lifting frame 11 and a tool clamping seat 12 positioned on the lifting frame 11. The lifting frame 11 can move up and down along the Z-axis and switch between a tool storage position P1 (such as Figure 2 ) and a tool changing preparation position P2 (such as Figure 6 ). The tool clamping seat 12 has a plurality of tool clamping parts 121 and stores a plurality of tool shanks A, as Figures 1 to 5 shown.

[0035] Such as Figure 1 and Figure 3As shown, in the embodiment of the present application, the tool storage device 7 further includes a fixed seat 20, a driving unit 30, and a plurality of Z-axis lifting units 40. The fixed seat 20 is disposed on the top of the column 5 of the processing machine 1 and extends toward the front side of the processing machine 1. The driving unit 30 has a driving source 31 and a connected driving shaft 32. The driving source 31 is a motor, and the driving shaft 32 is connected to the motor and mounted on the fixed seat 20. The plurality of Z-axis lifting units 40 are arranged at the tool storage position P1 and are respectively connected to the driving shaft 32 and each lifting frame 11, that is, the Z-axis lifting units 40 and the driving shaft 32 are disposed on the fixed seat 20.

[0036] Each Z-axis lifting unit 40 respectively has a driving gear 41, a clutch member 42, and a rack 43. The driving gear 41 is coaxially connected to the clutch member 42 to the driving shaft 32. The driving gear 41 meshes with the rack 43, and the rack 43 penetrates through the fixed seat 20 and is connected to the lifting frame 11. The clutch member 42 can perform a clutch action relative to the driving gear 41 by control. When the clutch member 42 is separated from the driving gear 41, the driving gear 41 is not driven by the driving shaft 32. When the clutch member 42 is engaged with the driving gear 41, the driving gear 41 can be driven by the driving shaft 32 to rotate. Thereby, when the clutch member 42 is connected to the driving gear 41 and can be driven by the driving shaft 32 for transmission, the driving gear 41 drives the rack 43 to displace along the Z-axis, so that the lifting frame 11 and the tool clamping seat 12 are displaced to Figure 6 the tool change preparation position P2.

[0037] As Figure 3 and Figure 4 and cooperate with Figure 2 and Figure 6 shown, the fixed seat 20 is provided with a limiting unit 21 on one side of each Z-axis lifting unit 40 for selectively limiting the height of the rack 43, so that the lifting frame 11 is maintained at the tool storage position P1 or the tool change preparation position P2. Among them, the limiting unit 21 has a limiting rod 211 and a pneumatic cylinder 212 for driving the limiting rod 211 to act. A plurality of limiting holes 431 are provided on one side of the rack 43. The limiting holes 431 are longitudinally arranged on the rack 43, and the number of the limiting holes 431 is three for the relative limiting rod 211 to extend into and insert, so as to limit the height position of the rack 43. For example, when the limiting rod 211 is inserted into the limiting hole 431 at the highest position, it means that the lifting frame 11 is located at the tool change preparation position P2; when the limiting rod 211 is inserted into the limiting hole 431 at the lowest position, it means that the lifting frame 11 is located at the tool storage position P1; when the limiting rod 211 is inserted into the limiting hole 431 at the middle position, the lifting frame 11 is located at the maintenance position for inspection and maintenance.

[0038] In addition, the Z-axis lifting unit 40 is provided with guide rods 44 on both sides of the driving gear 41. The guide rods 44 are slidably penetrated through the fixed seat 20 and connected to the relative lifting frame 11 to ensure the stability of the lifting frame 11 during lifting.

[0039] As shown Figure 5 in the figure, side rods 111 are provided on both sides of the lifting frame 11, and the side rods 111 have transverse grooves 112. The tool holder 12 and the side rods 111 have corresponding positioning blocks 122, and a part of the positioning blocks 122 can be connected by relatively sliding along the Y-axis with the transverse grooves 112 of the side rods 111. In the embodiment of the present application, there is a positioning member 113 between the positioning blocks 122 and the side rods 111, and the positioning member 113 can move relative to the Z-axis to cause a positioning relationship between the positioning blocks 122 and the side rods 111. The positioning member 113 is provided on the side rods 111, and the end of the positioning member 113 has an elastically telescopic bead 1131 for protruding or not protruding into the transverse groove 112, and a depression 1221 corresponding to the bead 1131 is provided on the top of the positioning block 122. When the positioning block 122 is connected to the transverse groove 112, the bead 1131 protrudes into the transverse groove 112 and is positioned in the depression 1221, so that the positioning block 122 and the side rods 111 form a positioning state. In addition, the bottom of the positioning block 122 has a connection hole 1222.

[0040] The tool changer 8 can disengage and return the tool holder 12 relative to the lifting frame 11 at the tool change preparation position P2, so as to drive the tool holder 12 to shift along the Y-axis to the tool change position P3 for the main shaft 3 to take or replace the tool handle A from the tool holder 12.

[0041] As Figure 5 and Figure 6 shown in the figure, the tool changer 8 includes a slide base 50, a pusher 60, a Y-axis drive unit 70 and an X-axis drive unit 80. The pusher 60 is provided on the slide base 50, the Y-axis drive unit 70 is provided between the column 5 and the frame 6 for driving the slide base 50 to displace along the Y-axis, and the X-axis drive unit 80 is provided between the slide base 50 and the pusher 60 for driving the pusher 60 to displace relative to the slide base 50 along the X-axis. Connecting columns 61 corresponding to the positioning blocks 122 of the tool holder 12 are provided on both sides of the pusher 60 for positioning the connection hole 1222 and the connecting columns 61 when the lifting frame 11 is displaced to the tool change preparation position P2. Among them, the Y-axis drive unit 70 includes components such as a slide rail, a slider, a motor and a rack. The rack is installed between the frame 6 and the column 5, the motor meshes with the rack with a gear, and the slide base 50 is driven by the cooperation of the slide rail and the slider to displace along the Y-axis by the motor; and the X-axis drive unit 80 includes components such as a slide rail, a slider, an electric motor and a screw. The slide rail and the slider of the X-axis drive unit 80 are provided between the pusher 60 and the slide base 50, and the electric motor drives the screw to act, so that the pusher 60 can displace relative to the slide base 50 along the X-axis.

[0042] The above description is about the case where the main shaft 3 only displaces on the Z-axis. If the main shaft 3 can displace along the X-axis and the Z-axis, the X-axis drive unit 80 is not required.

[0043] Next, please refer to Figures 6 to 10 as shown, which illustrates the steps and process of the tool loading operation of this application. As Figure 6 shown, one tool carrier unit 10 is driven by a corresponding Z-axis lifting unit 40, so that the lifting frame 11 drives the tool holder 12 to descend along the Z-axis to the tool change preparation position P2. At this time, the pusher 60 is driven by the slide 50 to be below the lifting frame 11, and the connecting column 61 is aligned with the connecting hole 1222. When the tool holder 12 descends along the Z-axis to the tool change preparation position P2, the connecting hole 1222 and the connecting column 61 are engaged and positioned with each other, and the tool holder 12 is fixed to the pusher 60.

[0044] As Figure 7 shown and in cooperation with Figure 5 , while the slide 50 displaces along the Y-axis and towards the main shaft 3, the pusher 60 drives the tool holder 12 to move towards the main shaft 3. At this time, the bead 1131 is elastically contracted under force so that it disengages from the recess 1221, and the positioning block 122 of the lifting frame 11 of the tool carrier unit 10 is disengaged from the tool holder 12.

[0045] As Figure 8 shown, continuing Figure 7 , after the lifting frame 11 is disengaged from the positioning block 122, the lifting frame 11 can rise along the Z-axis back to its original position, and the tool holder 12 moves towards the main shaft 3 and moves to the tool change position P3 below the main shaft 3.

[0046] As Figure 9 shown, after the main shaft 3 moves down along the Z-axis to connect the main shaft hole to the corresponding tool shank A of the tool holder 12 and completes the tool grasping action, it then moves up to its original position so that the main shaft 3 removes the tool shank A on the tool holder 12, and subsequent machining operations are carried out.

[0047] As Figure 10 shown, after the aforementioned tool loading operation is completed, the slide 50 drives the tool holder 12 to reset to the aforementioned Figure 6 tool change preparation position P2 to wait for the next tool change requirement. Accordingly, when it is necessary to replace the tool shank A of the main shaft 3 again, the tool holder 12 moves to the tool change position P3 according to the aforementioned actions with the empty tool clamping part 121 (without installing the tool shank A) for the old tool shank A on the main shaft 3 to be placed in the tool clamping part 121. Then, in cooperation with the X-axis displacement action of the aforementioned pusher 60 and the up and down displacement actions of the main shaft 3 along the Z-axis, the main shaft 3 connects and removes another tool shank A on the tool holder 12, and the new and old tool change operation can be completed. And when all the tool shanks A on the tool holder 12 have been used and replaced, the reverse operation can be carried out according to the aforementioned action description. The tool carrier unit 10 sends the tool holder 12 back to the tool storage position P1 as shown in Figure 2 , and then replaces the tool holder 12 of another new tool carrier unit 10. Thus, through the aforementioned structural principle, this application can achieve the purpose of tool loading and tool change.

[0048] It is worth mentioning that, in some embodiments, the processing machine 1 is of the gantry type, and the column 5 has a through space, so that the tool storage device 7 is arranged behind the column 5 and moves from the rear position to the front position for operation during tool change.

[0049] In some embodiments, when the number of the foregoing tool clamping seats 12 is small, the Z-axis lifting unit 40 can be replaced by a cylinder to control the up and down movement.

[0050] As Figure 11 shown, this is another embodiment of the present application. The difference from the foregoing embodiment is that the tool exchange device 8 can be installed on one side of the work platform 2, and the work platform 2 has the ability to displace along the X-axis and Y-axis. In this way, components such as the foregoing Y-axis drive unit 70 and X-axis drive unit 80 can be omitted.

[0051] In other possible embodiments, in addition to positioning the positioning block 122 of the tool clamping seat 12 and the side rod 111 by the elastic telescopic bead 1131 of the positioning member 113, a permanent magnet / electromagnet can also be used to replace the positioning member 113, so that the positioning block 122 and the side rod 111 are fixed to each other by magnetic adsorption. In addition to being applicable to vertical machining centers as described above, the present application can also be applied to horizontal machining centers. Only in the horizontal spindle direction of the horizontal machining center, the tool handle directions of storing and clamping tools of the tool clamping seat 12 are correspondingly changed to the horizontal direction, and the tool change operation can be smoothly carried out in cooperation with the present application when the spindle moves horizontally.

[0052] According to the above description, the present application has the following advantages:

[0053] 1. In the tool change operation of the present application, after the tool clamping seat 12 moves from the tool storage position P1 to the tool change preparation position P2, it is then driven by the slide seat 50 of the tool exchange device 8 to move down to the tool change position P3 for tool change operation, so that the tool clamping seat 12 only makes displacements in the Z-axis and Y-axis directions before the tool change position P3. In this way, the actions required for replacing the tool clamping seat 12 are simplified, the time for replacing the tool clamping seat 12 is greatly shortened, and the efficiency of tool change and processing is thereby improved.

[0054] 2. The tool storage device 7 of the present application is located in front of the spindle 3 and above the work platform 2, which can reduce the space occupied by the machine tool.

[0055] 3. The multiple tool carrying units 10 of the tool storage device 7 of the present application can store multiple sets of tool handles A at the same time for applications that require multiple tool numbers for processing, and can expand the tool change applicability to meet diverse processing requirements.

[0056] The above is an explanation of the present application with several embodiments. Those skilled in the art can make various different forms of changes without departing from the spirit and scope of the present application.
