Description

Technical Field

[0001] This application relates to the field of CNC machine tool equipment technology, and in particular to a hat-shaped tool magazine and a CNC machine tool. Background Technology

[0002] The tool magazine is an important functional component of CNC machining centers. It not only has the ability to store tools, but also accurately delivers the tools needed by the machining center to the tool change position. Through an automatic tool changer or the coordinated action of the tool magazine and the spindle, it can exchange the tool for the next process with the tool for the previous process on the spindle.

[0003] Common tool magazine types include disc-type, chain-type, and hood-type tool magazines. Hat-type tool magazines consist of multiple components, and assembly errors can easily occur during the assembly process. This can lead to the rotating disc of the hat-type tool magazine not being perpendicular to the axis of the spindle, which in turn can cause collisions or scrapes during tool loading and unloading. Utility Model Content

[0004] This application provides a hat-shaped tool magazine and a CNC machine tool, which can solve the problem in related technologies where assembly errors during the assembly process of parts cause the bearing surface of the rotating tool head of the tool magazine to be perpendicular to the axis of the spindle.

[0005] In a first aspect, embodiments of this application provide a conical tool magazine; the conical tool magazine is applied to a CNC machine tool, the CNC machine tool including a spindle for picking up and placing tools, the conical tool magazine including a drive module, an adjustment module and a tool head module, the adjustment module including a first base, a second base and a connector, the first base being mounted on the drive end of the drive module, the second base being connected to the first base via an adjustment component, the tool head module including a rotating tool head and a plurality of tool holders for storing tools, the rotating tool head being mounted on the second base, the rotating tool head having a bearing surface, all tool holders being located on the side of the bearing surface of the rotating tool head and connected to the rotating tool head, the adjustment component being configured to change the distance between the second base and the first base so that the bearing surface of the rotating tool head is perpendicular to the axis of the spindle.

[0006] Secondly, embodiments of this application provide a CNC machine tool; the CNC machine tool includes a frame, a spindle, and the aforementioned hat-shaped tool magazine, the spindle being mounted on the frame, and the drive module of the aforementioned hat-shaped tool magazine being mounted on the frame.

[0007] Based on the embodiments of the present application, the hat-shaped tool magazine and CNC machine tool are designed with a first base, a second base, and an adjustment component to connect the tool head module and the drive module. During the assembly of the hat-shaped tool magazine, the distance between the second base and the first base can be adjusted by the adjustment component, so that the position of the rotating tool head mounted on the second base can be adjusted. At the same time, the bearing surface of the rotating tool head can be made perpendicular to the axis of the spindle. This can eliminate the assembly error caused by the assembly of the hat-shaped tool magazine components, and also ensure that the bearing surface of the rotating tool head is perpendicular to the axis of the spindle. This ensures that the tool will not collide or scratch the tool holder during the subsequent tool picking and putting process of the spindle. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0017] Please refer to Figures 1-4 As shown, this application proposes a CNC machine tool that can perform semi-automatic or automatic machining processes such as cutting on corresponding products to be processed by using different types of cutting tools 4.

[0018] The CNC machine tool includes a frame (not shown in the figure), a spindle (not shown in the figure), and a tool magazine 1.

[0019] The frame serves as the structure of a CNC machine tool; the specific structure of the frame is not limited here, and designers can design it reasonably according to actual needs.

[0020] The spindle is used to pick up and put down the tool 4. The spindle can take the target tool 4 out of the tool magazine 1 (i.e., tool retrieval operation), and the spindle can also return the tool 4, after machining, to the tool magazine 1 (i.e., tool release operation). The spindle is mounted on the machine frame; the specific installation method between the spindle and the machine frame is not limited here, and the designer can make reasonable designs according to actual needs.

[0021] The spindle is used in conjunction with the tool magazine 1 to load and unload the tool 4, specifically as follows:

[0022] 1. Move the spindle along the Z-axis to a safe position;

[0023] 2-The conical tool magazine 1 moves toward the spindle in the preset direction OO' to the tool changing position. At this time, the axis of the spindle coincides with the center line of the tool holder 32 of the conical tool magazine 1.

[0024] 3- The spindle moves downward along the Z-axis to the tool 4 exchange position, so as to return the tool 4 that has completed the machining operation on the current spindle to the tool holder 32 of the hat tool magazine 1;

[0025] 4-After the tool holder 32 of the hat-shaped tool magazine 1 is confirmed to hold the tool, the spindle blows air to release the tool, and the tool release operation is completed;

[0026] 5. The spindle moves upward along the Z-axis to the transition position to prevent interference between the rotating tool head 31 of the hat-shaped tool magazine 1 and the spindle when it rotates;

[0027] The rotating tool head 31 of the 6-hat tool magazine 1 rotates to find the target tool 4 that the instruction requires to be replaced, and makes the center line of the target tool 4 coincide with the axis of the spindle;

[0028] 7. The spindle moves downward along the Z-axis to the tool 4 exchange position and performs a tool grabbing action. Then, the spindle's puller clamps the pull pin 401 on the tool holder of the tool 4, thus completing the tool removal operation.

[0029] The conical tool magazine 1 is used in conjunction with the spindle to retrieve and place the tool 4. The conical tool magazine 1 is the focus of this application, and the following description is based on... Figures 1-4 The specific structure of the straw hat-shaped sword magazine 1 will be described in detail.

[0030] like Figures 1-4 As shown, the straw hat-shaped tool magazine 1 includes a drive module 10, an adjustment module 20, and a tool head module 30.

[0031] The drive module 10 serves as the drive mechanism in the hat-shaped tool magazine 1 to generate driving force to drive the adjustment module 20 and the tool head module 30 to move along the preset direction OO' to the tool changing position. The specific structure of the drive module 10 will be described in detail below.

[0032] The drive module 10 is mounted on the rack. The specific installation method between the drive module 10 and the rack is not limited here, and the designer can make reasonable designs according to actual needs; for example, the drive module 10 can be detachably fixedly connected to the rack by at least one of the following methods: screw connection, snap-fit ​​connection or plug connection; or, for example, the drive module 10 can be non-detachably fixedly connected to the rack by riveting or welding.

[0033] The adjustment module 20 serves as an intermediate adjustment mechanism between the drive module 10 and the cutter head module 30. The machine operator can adjust the adjustment module 20 to level the rotating cutter head 31 of the cutter head module 30 (described below) so that the bearing surface 31a of the rotating cutter head 31 is perpendicular to the axis of the spindle, thereby ensuring the spindle's accurate loading and unloading of the tool 4.

[0034] like Figures 1-4As shown, the adjustment module 20 includes a first base 21, a second base 22, and an adjustment component 23.

[0035] The first base 21 serves as one of the components of the adjustment module 20. The specific structure of the first base 21 is not limited here, and designers can make reasonable designs according to actual needs; for example, the first base 21 may be, but is not limited to, a rectangular plate structure.

[0036] The first base 21 is mounted on the drive end of the drive module 10. The specific mounting method between the first base 21 and the drive end of the drive module 10 is not limited here; designers can design it reasonably according to actual needs. For example, the first base 21 can be detachably and fixedly connected to the drive end of the drive module 10 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the first base 21 can also be non-detachably and fixedly connected to the drive end of the drive module 10 by riveting or welding.

[0037] The second base 22 serves as another support for the adjustment module 20. The specific structure of the second base 22 is not limited here, and designers can make reasonable designs according to actual needs; for example, the second base 22 may be, but is not limited to, a rectangular plate structure.

[0038] The adjustment component 23 serves as an intermediate connector between the first base 21 and the second base 22, with the second base 22 connected to the first base 21 via the adjustment component 23. The specific form of the adjustment component 23 will be described in detail below.

[0039] like Figures 1-4 As shown, the cutter head module 30 serves as the fixture for the conical cutter magazine 1. The cutter head module 30 includes a rotating cutter head 31 and multiple tool holders 32 for storing the cutting tools 4.

[0040] The rotary cutter head 31 serves as a support platform for the cutter head module 30, supporting the tool holder 32. The rotary cutter head 31 is mounted on the second base 22. The specific installation method between the rotary cutter head 31 and the second base 22 is not limited here; designers can design it reasonably according to actual needs. For example, the rotary cutter head 31 can be detachably and fixedly connected to the second base 22 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the rotary cutter head 31 can also be non-detachably and fixedly connected to the second base 22 by riveting or welding, but not limited to this method.

[0041] The rotating cutter head 31 has a bearing surface 31a.

[0042] The tool holder 32 serves as a clamping component of the tool head module 30 to hold the tool 4. The tool holder 32 can be used to hold both the target tool 4 and the tool 4 that has completed the machining operation. All tool holders 32 are located on the same side as the bearing surface 31a of the rotating tool head 31, and all tool holders 32 are arranged at intervals around the rotation axis of the rotating tool head 31.

[0043] All tool holders 32 are connected to the rotating tool disc 31. Specifically, for each tool holder 32, the tool holder 32 includes a clamping arm 321 and a spring 322. There are two clamping arms 321, which are arranged opposite each other and spaced apart. The two clamping arms 321 are rotatably connected to the rotating tool disc 31 through a rotating shaft. The spring 322 is located between the two clamping arms 321 and its two ends are respectively connected to the ends of the two clamping arms 321. The ends of the two clamping arms 321 away from the spring 322 enclose a clamping space for holding the tool 4.

[0044] It is understandable that in many assembly steps, such as the assembly between the tool magazine 1 and the frame, the assembly between the drive module 10 and the frame, the assembly between the first base 21 and the drive end of the drive module 10, and the assembly between the second base 22 and the tool head module 30, any one or more assembly steps may have assembly errors. Ultimately, this will result in the bearing surface 31a of the rotating tool head 31 not being perpendicular to the axis of the spindle after the equipment is assembled. As a result, during the subsequent process of the spindle picking up and placing the tool 4, the tool 4 is very likely to be damaged due to collision or scraping against the tool holder 32. By designing the adjustment component 23, which is configured to change the distance between the second base 22 and the first base 21, the bearing surface 31a of the rotating cutter head 31 is made perpendicular to the axis of the spindle. This allows the distance between the second base 22 and the first base 21 to be changed directly by adjusting the adjustment component 23 during equipment assembly. This adjusts the position of the rotating cutter head 31 mounted on the second base 22 so that the bearing surface 31a of the rotating cutter head 31 is perpendicular to the axis of the spindle. Consequently, during the subsequent spindle loading and unloading of the cutter head 4, the cutter head 4 will not be subject to collisions or scrapes against the tool holder 32, thus effectively preventing damage to the cutter head 4.

[0045] like Figures 4-6 As shown, the first base 21 is provided with a plurality of first threaded holes 21a, and the second base 22 is provided with a plurality of through holes 22a corresponding to the plurality of first threaded holes 21a on the side opposite to the first base 21. The adjusting assembly 23 includes a plurality of first adjusting studs 231, each first adjusting stud 231 being threadedly connected to a first threaded hole 21a; the adjusting assembly 23 also includes a plurality of second adjusting studs 232, each second adjusting stud 232 passing through a through hole 22a and being threadedly connected to a corresponding first adjusting stud 231.

[0046] By designing a first adjusting stud 231 and a second adjusting stud 232, the first adjusting stud 231 is threadedly connected to the first threaded hole 21a, and the second adjusting stud 232 passes through the through hole 22a and is threadedly connected to the corresponding first adjusting stud 231. Thus, when the rotary cutter head 31 needs to be leveled, the machine operator can use tools such as a level or laser line projector to adjust the distance between the second base 22 and the first base 21 by rotating the first adjusting stud 231 and the second adjusting stud 232 until the bearing surface 31a of the rotary cutter head 31 is perpendicular to the axis of the spindle, thereby completing the leveling of the rotary cutter head 31.

[0047] like Figures 4-6 As shown, the first base 21 includes a first substrate, which is rectangular. The second base 22 includes a second substrate, which is also rectangular. There are four through holes 22a, positioned near the corners of the second substrate; four first threaded holes 21a; four first adjusting studs 231; and four second adjusting studs 232. The four through holes 22a, four first threaded holes 21a, four first studs 231a, and four second studs 232a are arranged in a one-to-one correspondence. By placing the four through holes 22a at the four corners of the rectangular second substrate, four connection points are formed between the second substrate and the first substrate via the four first adjusting studs 231 and the two adjusting studs 232. The four connection points are evenly distributed, enhancing the connection stability between the second substrate and the first substrate. It is worth mentioning that during the leveling process of the rotary cutter head 31, when the machine operator adjusts one of the first adjusting studs 231 and its corresponding second adjusting stud 232, the remaining three first adjusting studs 231 and their corresponding three second adjusting studs 232 form a triangular stable structure to assist in supporting the cutter head module 30, thereby improving the convenience of the leveling operation of the rotary cutter head 31.

[0048] Specifically, such as Figures 4-6As shown, the first adjusting stud 231 includes a first stud 231a and a first nut 231b fixedly connected to one end of the first stud 231a. The first nut 231b has a second threaded hole 231c on the side opposite to the first stud 231a. The second adjusting stud 232 passes through a through hole 22a and is threadedly connected to the second threaded hole 231c. The first stud 231a and the first nut 231b can be, but are not limited to, formed as a single unit by injection molding or 3D printing. The adjustment of the distance between the second base 22 and the first base 21 is mainly achieved by adjusting the relative position of the first stud 231a of the first adjusting stud 231 in the first threaded hole 21a; by designing a second threaded hole 231c on the side of the first nut 231b away from the first stud 231a, the second adjusting stud 232 passes through the through hole 22a and is threadedly connected to the second threaded hole 231c, so that the assembly between the second base 22 and the first base 21 can be achieved by connecting the second adjusting stud 232 and the first adjusting stud 231.

[0049] like Figures 4-6 As shown, the second adjusting stud 232 includes a second stud 232a and a second nut 232b fixedly connected to one end of the second stud 232a. The second nut 232b has a groove on its side opposite to the second stud 232a. The second stud 232a and the second nut 232b can be, but are not limited to, formed as a single piece by injection molding or 3D printing. The groove can be, but is not limited to, a slotted groove, a cross-shaped groove, or a hexagonal groove. When the rotating cutter head 31 needs to be leveled, the machine operator can select a suitable screwdriver according to the shape of the cutter groove. The machine operator holds the screwdriver with one hand and inserts the end of the screwdriver into the cutter groove of the second nut 232b of the second adjusting stud 232. The machine operator holds the wrench with the other hand and locks the wrench into the first nut 231b of the first adjusting stud 231. The machine operator rotates the screwdriver (while the wrench remains stationary) to release the first nut 231b of the first adjusting stud 231 and the second nut 232b of the second adjusting stud 232 from the second base 22, so as to facilitate the subsequent adjustment of the distance between the second base 22 and the first base 21.

[0050] It should be noted that after the rotary cutter head 31 is leveled, the first nut 231b of the first adjusting stud 231 and the second nut 232b of the second adjusting stud 232 are respectively locked to the second base 22 from opposite sides (that is, the end faces of the first nut 231b of the first adjusting stud 231 and the second nut 232b of the second adjusting stud 232 are tightly fitted to the first base 21). It is also understood that after the rotary cutter head 31 is leveled, the positions of all the first adjusting studs 231 relative to their corresponding first threaded holes 21a are not necessarily the same, that is, the adjustment distances of all the first adjusting studs 231 are not necessarily the same.

[0051] Other design details may include, but are not limited to, one or more of the following embodiments.

[0052] In the first embodiment, the adjusting assembly 23 further includes a plurality of fastening nuts 233, each fastening nut 233 being threadedly connected to a first stud 231a of a first adjusting stud 231, and the plurality of fastening nuts 233 being located on the side of the first base 21 facing the second base 22. By designing the fastening nuts 233, after the rotating cutter head 31 has been leveled, the machine operator can rotate the fastening nuts 233 to make the end face of the fastening nuts 233 abut against the surface of the first base 21 facing the second base 22, preventing loosening between the first adjusting stud 231 and the first base 21, thus further enhancing the connection stability between the second base 22 and the first base 21.

[0053] In the second embodiment, the through hole 22a is a countersunk hole. This design allows the second nut 232b of the second adjusting stud 232 to be fitted into the countersunk hole.

[0054] In the third embodiment, the outer surface of the first nut 231b includes multiple planes (two or more), which are arranged around the axis of the first adjusting stud 231. By designing multiple planes on the outer surface of the first nut 231b, the planes are designed to provide wrench slots, so that the machine operator can rotate the first adjusting stud 231 with a wrench.

[0055] Of course, the first base 21 may also have multiple first through holes (not shown in the figure), and the second base 22 may have multiple second through holes (not shown in the figure) corresponding to the multiple first through holes. In this case, the adjusting component 23 includes multiple bolts (not shown in the figure), each bolt passing through a second through hole and a first through hole from bottom to top. The adjusting component 23 also includes multiple first nuts (not shown in the figure), all of which are located between the second base 22 and the first base 21, and each first nut is threadedly connected to the stud of a bolt, and the end faces of all the first nuts abut against the second base 22. The adjusting component 23 also includes multiple second nuts (not shown in the figure), all of which are located on the side of the first base 21 away from the second base 22, and each second nut is threadedly connected to the stud of a bolt, and the end faces of all the second nuts abut against the first base 21. In this way, the machine operator can use a wrench to turn the second nut to change the relative position between the second nut and the bolt stud, thereby adjusting the distance between the second base 22 and the first base 21, so that the bearing surface 31a of the rotating cutter head 31 is perpendicular to the axis of the spindle.

[0056] like Figures 1-4 As shown, the drive module 10 includes a frame 11, a slide rail 12, a sliding seat 13, and a drive component 14. The slide rail 12 is mounted on the frame 11 and extends along a preset direction OO'. The sliding seat 13 serves as the drive end of the drive module 10 and is slidably connected to the slide rail 12. A first base 21 is mounted on the sliding seat 13. The drive component 14 is mounted on the frame 11 and is connected to the sliding seat 13 to drive the sliding seat 13 to move relative to the slide rail 12.

[0057] The frame 11 serves as a support for the drive module 10 and is mounted on the rack. The specific installation method between the frame 11 and the rack is not limited, and designers can make reasonable designs according to actual needs. For example, the frame 11 can be detachably and fixedly connected to the rack by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the frame 11 can be non-detachably and fixedly connected to the rack by riveting or welding.

[0058] The slide rail 12 serves as the track for the sliding seat 13 to move. The specific installation method between the slide rail 12 and the frame 11 is not limited, and the designer can make a reasonable design according to the actual needs. For example, the slide rail 12 can be detachably and fixedly connected to the frame by at least one of the following methods: screw connection, snap connection or plug connection. For another example, the slide rail 12 can also be non-detachably and fixedly connected to the frame by riveting or welding.

[0059] The sliding seat 13 serves as the driving end of the drive module 10 and is slidably connected to the slide rail 12. The specific installation method between the first base 21 and the sliding seat 13 is not limited here, and the designer can make a reasonable design according to actual needs. For example, the first base 21 can be detachably fixedly connected to the sliding seat 13 by at least one of the following methods: screw connection, snap connection, or plug connection. Alternatively, the first base 21 can also be non-detachably fixedly connected to the sliding seat 13 by riveting or welding.

[0060] The drive component 14 serves as a power source to generate driving force. The specific installation method between the drive component 14 and the frame 11 is not limited here; designers can design it reasonably according to actual needs. For example, the drive component 14 can be detachably and fixedly connected to the frame by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the drive component 14 can be non-detachably and fixedly connected to the frame by riveting or welding. The drive component 14 can be a motor, in which case the motor shaft is connected to a screw rod, and the screw rod is threadedly connected to the sliding seat 13. The drive component 14 can also be a cylinder 141, in which case the piston rod of the cylinder 141 is fixedly connected to the sliding seat 13.

[0061] The driving component 14 drives the sliding seat 13 to move relative to the slide rail 12. The movement of the sliding seat 13 causes the first base 21 connected to it to move along the preset direction OO'. The movement of the first base 21 drives the second base 22 to move along the preset direction OO' through the adjustment component 23. The movement of the second base 22 causes the rotating tool disc 31 connected to it to move along the preset direction OO' to the above-mentioned tool changing position, so that the hat-shaped tool magazine 1 can cooperate with the spindle to realize the picking and putting of the tool 4.

[0062] Specifically, the drive component 14 includes a cylinder 141 mounted on the frame 11. The piston rod of the cylinder 141 is fixedly connected to the sliding seat 13, and the piston rod of the cylinder 141 extends and retracts along a preset direction OO'. The cylinder 141 is connected to an air source and is fixedly connected to the frame 11 by screws. By designing the drive component 14 as a cylinder 141, the extension movement of the piston rod of the cylinder 141 along the preset direction OO' drives the sliding seat 13, which is fixedly connected to it, to move relative to the slide rail 12 along the preset direction OO'. The movement of the sliding seat 13 drives the first base 21 connected to it to move along the preset direction OO'. The movement of the first base 21 drives the second base 22 to move along the preset direction OO' through the adjustment component 23. The movement of the second base 22 drives the rotating tool disc 31 connected to it to move along the preset direction OO' to the aforementioned tool changing position, so that the tool magazine 1 and the spindle can cooperate to realize the picking and putting of the tool 4.

[0063] like Figures 1-4As shown, the sliding seat 13 includes a sliding plate 131, a slider 132, and a connecting frame 133. The sliding plate 131 is fixedly connected to the piston rod of the cylinder 141. The slider 132 is fixedly connected to the side of the sliding plate 131 facing the slide rail 12, and the slider 132 is slidably connected to the slide rail 12. The connecting frame 133 is fixedly connected to the side of the sliding plate 131 facing away from the slide rail 12. The first base 21 is fixedly connected to the connecting frame 133 and the sliding plate 131 by screws. Specifically, the slider 132 is fixedly connected to the interactive board by screws; the connecting frame 133 is fixedly connected to the sliding plate 131 by screws. This design allows the sliding seat 13 to achieve a slidable connection with the slide rail 12 via the slider 132, and a fixed connection between the sliding seat 13 and the first base 21 via the connecting frame 133 and the sliding plate 131. The structure is simple and easy to implement.

[0064] The following combination Figures 1-6 The leveling operation of the rotating cutterhead 31 of the conical cutter magazine 1 will be described in detail.

[0065] The machine operator uses a screwdriver and a wrench. One hand holds the screwdriver and inserts the end of the screwdriver into the slot of the second nut 232b of the second adjusting stud 232, while the other hand holds the wrench and locks it onto the fastening nut 233.

[0066] The machine operator first turns the wrench (while the screwdriver remains stationary), and the tightening nut 233 rotates and moves away from the first base 21.

[0067] After the fastening nut 233 moves a certain distance away from the first base 21, the machine operator holds the wrench with his other hand and locks the wrench onto the first nut 231b of the first adjusting stud 231.

[0068] The machine operator rotates the screwdriver (while the wrench remains stationary) to move the second adjusting stud 232 away from the first adjusting stud 231, thus releasing the second base 22 and allowing adjustment space for the first adjusting stud 231. Using a level or laser line projector as a leveling reference, the machine operator rotates the wrench again (while the screwdriver remains stationary) to move the first adjusting stud 231 up or down to the appropriate position. Finally, the machine operator rotates the screwdriver again (while the wrench remains relatively stationary) to move the second adjusting stud 232 closer to the first adjusting stud 231, so that the end face of the second nut 232b of the second adjusting stud 232 and the end face of the first nut 231b of the first adjusting stud 231 respectively abut against the opposite sides of the second base 22, thereby locking the second base 22 with the second nut 232b of the second adjusting stud 232 and the first nut 231b of the first adjusting stud 231. By adjusting the multiple second adjusting studs 232 and the corresponding multiple first adjusting studs 231 one by one, the leveling operation of the rotating cutter head 31 can be completed, so that the bearing surface 31a of the rotating cutter head 31 is perpendicular to the axis of the spindle.

[0069] Finally, the machine operator turns the wrench (while the screwdriver remains stationary), causing the fastening nut 233 to rotate and move towards the first base 21 until it is pressed against the surface of the first base 21, thus completing the leveling operation of the rotating cutter head 31.
