Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a tool magazine for a vertical five-axis machine tool and a vertical five-axis machine tool. Background Technology

[0002] Five-axis CNC machining technology is one of the core technologies of modern high-end equipment manufacturing, mainly used for machining parts with complex curved surfaces and high precision requirements. Vertical five-axis machine tools, with their wide machining range, high flexibility, and excellent cutting performance, are widely used in aerospace, automotive manufacturing, precision mold making, and medical device industries. In the automated operation system of a vertical five-axis machine tool, the tool magazine is an indispensable key component, used to centrally store the tools required for machining and to work with the spindle and tool changer to achieve automatic and rapid tool exchange. The performance of the tool magazine directly affects the degree of automation and overall machining efficiency of the machine tool.

[0003] However, existing vertical five-axis machine tool magazines have the following technical defects: First, insufficient transmission rigidity. During high-speed tool changes, long-term storage of heavy-duty tools, and long-term operation, the transmission mechanism of existing tool magazines is prone to elastic deformation, leading to tool positioning deviations and affecting the machining accuracy of the workpiece. Second, low positioning accuracy. Affected by assembly errors between transmission components and the impact and vibration during tool changes, existing tool magazines cannot achieve precise positioning of the tool head or tool holder. Under long-term high-intensity use, this can easily lead to tool changing failures, reducing the stability and reliability of machine tool operation. Summary of the Invention

[0033] The following is combined Figures 1 to 8 The present invention describes a tool magazine for a vertical five-axis machine tool and a vertical five-axis machine tool.

[0034] An embodiment of the first aspect of the present invention provides a tool magazine for a vertical five-axis machine tool, such as Figures 1 to 4 As shown, the tool magazine includes a base 100 and a drive assembly 200, a second transmission component 300, and a gear plate component 400 disposed on the base 100.

[0035] The drive assembly 200 includes a drive member 210 and a first transmission component 220. The drive member 210 is disposed on the base 100, and the first transmission component 220 is connected to the drive member 210 in a transmission manner. The second transmission component 300 includes a transmission shaft 310 and a transmission gear 320. The transmission shaft 310 is rotatably disposed on the base 100 and is connected to the first transmission component 220 in a transmission manner. The transmission gear 320 is disposed on the transmission shaft 310. The gear disk component 400 includes a supporting outer ring 410 and a gear disk 420. The supporting outer ring 410 is disposed on the base 100, and the gear disk 420 is rotatably supported on the supporting outer ring 410. An internal gear ring for meshing with the transmission gear 320 is formed on the inner circumferential surface of the gear disk 420. A plurality of tool clip assemblies 430 are arranged circumferentially on the gear disk 420.

[0036] Specifically, the drive assembly 200 includes a drive member 210 and a first transmission component 220. The drive member 210 is fixedly mounted on the base 100, and the first transmission component 220 is drivenly connected to the output end of the drive member 210 to receive the power output by the drive member 210. The second transmission component 300 includes a drive shaft 310 and a transmission gear 320. The drive shaft 310 is integrally formed from a high-strength alloy and is rotatably mounted on the base 100 via a bearing assembly. The drive shaft 310 is drivenly connected to the first transmission component 220, thereby transmitting the power of the drive assembly 200 to the second transmission component 300. The transmission gear 320 is fixedly mounted on the drive shaft 310 and rotates synchronously with the drive shaft 310. The gear disk component 400 includes a supporting outer ring 410 and a gear disk 420. The supporting outer ring 410 is disposed on the base 100. The gear disk 420 is rotatably supported on the inner circumferential surface of the supporting outer ring 410 by rolling elements, so that the gear disk 420 can rotate freely relative to the supporting outer ring 410 and the base 100. An internal gear ring is formed on the inner circumferential surface of the gear disk 420. The internal gear ring meshes with the external teeth of the transmission gear 320, thereby transmitting the power of the second transmission component 300 to the gear disk 420. A plurality of tool clamping assemblies 430 are arranged circumferentially on the gear disk 420. Each tool clamping assembly 430 is used to clamp the tool 700. The tool clamping assembly 430 and the gear disk 420 adopt an interference fit to ensure that the tool 700 is accurately positioned and moves sequentially to the tool changing position as the gear disk 420 rotates. Thus, the power output by the drive component 210 is transmitted sequentially to the gear plate 420 via the first transmission component 220 and the second transmission component 300. The drive gear plate 420 drives the tool holder assembly 430 to rotate, thereby achieving the switching of the tool 700.

[0037] It should be noted that in existing technologies, a rotating disk is typically mounted on the motor output shaft, with the inner ring of the rotating disk connected to the motor output shaft. Because multiple tool holder assemblies are required to accommodate multiple tools, the outer diameter of the rotating disk is relatively large, and the outer ring area where the tool holder assemblies are mounted is far from the support point (inner ring), forming a cantilever structure. Under this structure, the rotating disk has a large moment of inertia, and it needs to withstand a large inertial torque during tool changes, starting, stopping, and indexing. Simultaneously, during tool gripping and insertion / removal, the tool holder assembly is subjected to a downward force. This force, with the inner ring support point of the rotating disk as the fulcrum, generates a large deflection torque at the outer ring position, making the rotating disk prone to elastic deformation during long-term use, and even breakage at the inner ring connection or weak points of the disk body. In contrast, in this embodiment, the outer ring 410 is provided on the base 100, and the gear disk 420 is rotatably supported on the outer ring 410, so that the outer ring area of ​​the gear disk 420 obtains continuous rigid support. The force path of the gear disk 420 is the outer ring support type. When the impact load during the tool changing process is applied to the tool holder assembly 430, the force on the gear disk 420 is transmitted to the base 100 through the outer ring 410. The load transmission path is short and the force flow is continuous, which effectively resists the downward deflection torque, suppresses the deformation and vibration of the gear disk 420, avoids the risk of fracture caused by the cantilever structure, and improves the structural stability and positioning accuracy of the gear disk 420 under large diameter and multi-tool position working conditions.

[0038] The tool magazine for a vertical five-axis machine tool provided in this embodiment of the invention provides reliable radial and axial support for the gear disc 420 by setting the outer support ring 410 on the base 100 and rotatably supporting the gear disc 420 on the outer support ring 410. This effectively resists the deflection torque and impact load generated by the tool holder assembly 430 and the tool 700 during high-speed tool changing and heavy-duty tool storage, enhances the transmission rigidity of the system, and suppresses the elastic deformation of the gear disc 420. At the same time, the drive assembly 200 meshes with the internal gear ring on the inner circumferential surface of the gear disc 420 through the transmission gear 320 of the second transmission component 300, forming a compact transmission path from the drive component 210, the first transmission component 220, the second transmission component 300 to the gear disc 420. Thus, the present invention effectively enhances the anti-deflection capability of the gear disc 420 by providing rigid support for the outer ring 410, and enables the gear disc 420 to drive the tool holder assembly 430 to achieve high-precision indexing and positioning through the meshing of the transmission gear 320 with the inner gear ring of the gear disc 420. This effectively avoids positioning deviation and tool changing failure, and improves the positioning accuracy of the tool magazine, the stability of long-term operation, and the machining accuracy of the workpiece.

[0039] In one embodiment of the present invention, such as Figure 3 , Figure 4 and Figure 6As shown, the driving component 210 is located in the middle of the base 100. The driving component 210 adopts a driving motor, and the torque output by the driving motor is transmitted to the second transmission component 300 through the first transmission component 220.

[0040] Specifically, the first transmission component 220 is a transmission reduction mechanism, including a first transmission wheel 221, a second transmission wheel 222, and a transmission element 223. The first transmission wheel 221 is a small pulley, fixedly mounted on the output shaft of the drive motor; the second transmission wheel 222 is a large pulley, fixedly mounted on the transmission shaft 310. The small pulley and the large pulley are connected by the transmission element 223, and the torque output by the drive motor is transmitted sequentially through the small pulley, the transmission element 223, and the large pulley to the transmission shaft 310 of the second transmission component 300. By selecting small and large pulleys of different diameters, the transmission ratio of the first transmission component 220 can be changed, thereby adapting to different specifications of drive motors, meeting the torque and speed requirements of the tool magazine under different working conditions, and improving the versatility of the tool magazine.

[0041] It should be noted that in other embodiments, the first transmission wheel 221 and the second transmission wheel 222 may also be gears, and the transmission component 223 may be a chain or a synchronous belt to achieve gear meshing transmission; or other forms of flexible transmission elements may be used, as long as the power transmission between the first transmission wheel 221 and the second transmission wheel 222 can be achieved.

[0042] In one embodiment of the present invention, the transmission gear 320 and the transmission shaft 310 are interference fit, and the meshing surface of the transmission gear 320 is hardened. At the same time, the meshing clearance is finely adjusted by the tensioning sleeve 340 to eliminate transmission clearance and backlash error, thereby achieving high rigidity and high precision transmission.

[0043] In one embodiment of the present invention, such as Figures 4 to 6 As shown, the second transmission component 300 also includes a bearing assembly, and the transmission shaft 310 is rotatably supported on the base 100 via the bearing assembly. The transmission shaft 310 is arranged vertically, and a transmission gear 320 is fixed to the middle of the transmission shaft 310. Specifically, the transmission gear 320 is connected to the transmission shaft 310 via a key and is used to mesh with the internal gear ring of the gear disk 420 to drive the gear disk 420 to rotate.

[0044] Optionally, the bearing assembly includes a first bearing 331 component and a second bearing 333 component, both of which are disposed between the drive shaft 310 and the base 100, and are located on both sides of the drive gear 320 respectively.

[0045] Specifically, the first bearing 331 component is disposed on the upper part of the transmission shaft 310. The first bearing 331 component includes a first bearing 331 and a first connecting seat 332. The first bearing 331 is sleeved on the upper end of the transmission shaft 310 and is fixedly installed on the base 100 through the first connecting seat 332. In this embodiment, the first bearing 331 is a single-row deep groove ball bearing, which is used to bear radial load and provide rotational support.

[0046] The second bearing 333 component is disposed at the lower part of the drive shaft 310. The second bearing 333 component includes a second bearing 333 and a second connecting seat 334. The second bearing 333 is sleeved on the lower end of the drive shaft 310 and is fixedly installed on the base 100 through the second connecting seat 334. In this embodiment, the second bearing 333 includes two angular contact bearings arranged face-to-face to simultaneously bear radial loads and bidirectional axial loads, significantly improving the radial and axial rigidity of the shaft system and enhancing the support rigidity and stability of the lower end of the drive shaft 310.

[0047] It is understandable that the drive shaft 310 is rotatably supported on the base 100 by a single-row deep groove ball bearing at the upper end and two angular contact bearings at the lower end, and the bearing assembly is fixed to the base 100 by the first connecting seat 332 and the second connecting seat 334, so as to ensure that the drive shaft 310 maintains stable positional accuracy under high-speed rotation and tool changing impact load.

[0048] In one embodiment of the present invention, such as Figures 4 to 6 As shown, the second transmission component 300 also includes a tensioning sleeve 340, which is disposed between the transmission shaft 310 and the second transmission wheel 222.

[0049] Specifically, the second transmission wheel 222 is installed at the upper end of the transmission shaft 310, and the tensioning sleeve 340 is disposed between the transmission shaft 310 and the second transmission wheel 222. By adjusting the tightness of the tensioning sleeve 340, the circumferential and radial positions of the second transmission wheel 222 relative to the transmission shaft 310 can be slightly adjusted, thereby changing the meshing clearance between the transmission gear 320 and the internal gear ring of the gear disc 420. In this way, by utilizing the fine-tuning function of the tensioning sleeve 340, assembly clearance and backlash errors in the transmission can be effectively eliminated, avoiding transmission lag and positioning deviation caused by clearance, thereby achieving high rigidity and high precision power transmission and ensuring the accuracy and stability of tool changing in long-term operation of the tool magazine.

[0050] In one embodiment of the present invention, the gear plate component 400 adopts a high-precision indexing gear plate 420 bearing structure, and its indexing accuracy can be controlled within 0.005°, thereby further ensuring the tool changing positioning accuracy.

[0051] In one embodiment of the present invention, such as Figure 1 , Figure 6 and Figure 7 As shown, the tool magazine also includes a vibration damping component 500 disposed between the outer support ring 410 and the base 100. The vibration damping component 500 is used to buffer the impact load transmitted to the gear plate component 400 during the tool changing process.

[0052] Optionally, the vibration damping component 500 includes an elastic element 510 and a positioning element 520. The outer support ring 410 is supported on the base 100. The elastic element 510 is disposed between the outer support ring 410 and the base 100. The positioning element 520 is arranged vertically and is disposed on one of the outer support ring 410 and the base 100. The other is provided with a guide hole for the positioning element 520 to slide vertically. The elastic element 510 provides elastic support force to the outer support ring 410. The positioning element 520 cooperates with the guide hole to limit the vertical movement range of the outer support ring 410 and provide guidance for it.

[0053] In this embodiment, the elastic element 510 is a high-strength damping spring, and the positioning element 520 is a positioning bolt. One end of the positioning bolt is fixed to the supporting outer ring 410, and its rod extends into the corresponding guide hole on the base 100. The damping spring is sleeved on the outside of the positioning bolt. To accommodate the elastic element 510, the upper end face of the base 100 or the lower end face of the supporting outer ring 410 is provided with an installation notch, or both are provided with installation notches, so as to jointly enclose and form an installation space for accommodating the damping spring. In the natural state where the blade clamp assembly 430 is not subjected to external force, the damping spring applies an upward force to the supporting outer ring 410, so that the supporting outer ring 410 and the base 100 maintain a preset gap, and the connection and guidance between the supporting outer ring 410 and the base 100 are realized by the cooperation of the positioning bolt and the guide hole.

[0054] When the impact load during tool changing is applied to the tool holder assembly 430, the supporting outer ring 410 undergoes a slight vertical displacement relative to the base 100, compressing the damping spring. The damping spring absorbs the impact energy through elastic deformation, prolonging the impact time and significantly reducing the peak load transmitted to the gear plate assembly 400 and the transmission system. Thus, through this buffering mechanism, the impact load is buffered by the damping spring before being transmitted to the base 100, avoiding the rigid direct transmission of the impact force. This effectively reduces wear and loosening of components, maintains a stable meshing state between the transmission gear 320 and the internal gear ring, thereby extending the tool magazine's service life and maintaining the overall operational stability of the machine tool.

[0055] In one embodiment of the present invention, the base 100 is made of cast iron in one piece to eliminate internal stress, reduce the deformation of the installation foundation, and further enhance the vibration reduction effect.

[0056] In one embodiment of the present invention, the outer ring 410 is provided with a tool position identifier, and the gear disk 420 is provided with a plurality of tool position marks 440 that cooperate with the tool position identifier. The plurality of tool position marks 440 are arranged along the circumference of the gear disk 420.

[0057] Specifically, such as Figure 1 , Figure 6 and Figure 7 As shown, a tool position identifier, such as an coded sensor, is installed at the tool change position corresponding to the outer ring 410. Multiple tool position markers 440 are arranged circumferentially on the gear disc 420, their number equal to that of the tool holder assembly 430 and their positions corresponding one-to-one. Each tool position marker 440 has a unique coding feature. When the gear disc 420 rotates, the tool position identifier located at the tool change position reads the coding information of the current tool position marker 440 to obtain the current tool number and controls the drive assembly 200 to rotate the target tool to the tool change position. By adding tool position markers 440, the tool position can be fed back in real time, further improving tool change accuracy.

[0058] Optionally, a proximity switch is provided on the outer support ring 410, and only one sensor is provided on the outer circumference of the gear disk 420 corresponding to a certain reference tool position (e.g., tool position 1). Each rotation of the gear disk 420 causes the sensor to pass the proximity switch once, and the proximity switch outputs a counting pulse. The reference tool position corresponding to this pulse moment is used as the reference zero point for the circumferential position of the gear disk 420. During tool changing, the current tool number (i.e., the tool position number corresponding to the current stopping position of the gear disk 420) is obtained. Based on the difference between the target tool number and the current tool number, and combined with the total number of tool holder assemblies 430 on the gear disk 420, the angle that the gear disk 420 needs to rotate is calculated. The drive assembly 200 is then controlled to drive the gear disk 420 to rotate the corresponding angle, ensuring the target tool accurately reaches the tool changing position. Simultaneously, a photoelectric sensor (such as a diffuse reflection switch) is installed on the outer support ring 410 to detect whether a tool is present at the tool changing position, ensuring the safe execution of the tool changing action.

[0059] In one embodiment of the present invention, the tool magazine further includes an adjustment mechanism 600, which is disposed on the base 100 and is used to adjust the position of the base 100.

[0060] Optionally, the adjustment mechanism 600 includes multiple adjustment components disposed at the bottom of the base 100. Each adjustment component includes an adjustment block 610, a telescopic block 620, a support wheel 630, and an adjustment element 640. The adjustment block 610 is fixed to the bottom of the base 100; the upper end of the telescopic block 620 is slidably inserted into the adjustment block 610; the support wheel 630 is connected to the lower end of the telescopic block 620; and the adjustment element 640 is vertically disposed on the adjustment block 610 and threadedly connected to the upper end of the telescopic block 620, for adjusting the vertical position of the telescopic block 620 relative to the adjustment block 610.

[0061] In this embodiment, as Figure 1 and Figure 8 As shown, the base 100 has four mounting plates extending outward in a horizontal direction at its bottom, forming a continuous quadrilateral ring structure (i.e., a full ring of mounting plates) around the base 100. An adjustment component is provided at each of the four corners of this full ring of mounting plates, for a total of four adjustment components arranged in a rectangular pattern to ensure balanced force distribution on the base 100.

[0062] Each adjustment component includes an adjustment block 610, a telescopic block 620, a support wheel 630, and an adjustment element 640. The adjustment block 610 is fixedly installed above the mounting plate and has a vertically penetrating mounting hole. The mounting plate has a mounting notch located directly below the mounting hole, allowing the telescopic block 620 and the support wheel 630 to pass through.

[0063] The upper end of the telescopic block 620 is formed as a screw section, which extends into the mounting hole. The upper end of the telescopic block 620 and the mounting hole are in a precision clearance fit with a clearance of 0.01~0.02mm to form a sliding guide structure.

[0064] Support wheels 630 are connected to the lower end of telescopic block 620. Preferably, there are two support wheels 630 arranged side by side, and the two support wheels 630 are connected by a connecting rod. The connecting rod is fixed to the lower end of telescopic block 620 in the horizontal direction, so that the two support wheels 630 are located on both sides of telescopic block 620 respectively; the axes of the support wheels 630 of all adjustment components are parallel to each other.

[0065] The adjusting component 640 is vertically oriented and is a hollow reverse bolt. The lower end of the adjusting component 640 has an internally threaded hole and is positioned within the mounting hole, forming a threaded fit. The screw section at the upper end of the telescopic block 620 extends into the internally threaded hole at the lower end of the adjusting component 640, creating a threaded fit. The lower outer wall of the adjusting component 640 has external threads, and the inner wall of the hole has internal threads. The external threads of the adjusting component 640 and the internal threads of the mounting hole form a first threaded fit, while the internal threads of the adjusting component 640 and the screw section at the upper end of the telescopic block 620 form a second threaded fit. The directions of rotation of the first and second threaded fits are opposite. Specifically, in this embodiment, the first threaded fit is a right-hand thread, and the second threaded fit is a left-hand thread.

[0066] Since the adjusting component 640 is threadedly engaged with the mounting hole, and the adjusting component 640 is also threadedly engaged with the screw section of the telescopic block 620, the rotational motion is converted into the vertical linear motion of the telescopic block 620 relative to the adjusting block 610, thereby realizing the up-and-down movement of the support wheel 630, with an adjustment range of 0~5mm.

[0067] By rotating the adjusting component 640, which has internal and external threads that rotate in opposite directions, the adjusting component 640 moves vertically relative to the adjusting block 610. Simultaneously, the telescopic block 620 moves in the opposite direction relative to the adjusting component 640. The combined effect of these movements adjusts the vertical position of the telescopic block 620. Changing the rotation direction of the adjusting component 640 controls the raising and lowering of the support wheel 630, with an adjustment range of 0-5mm. When the support wheel 630 extends downwards from the mounting notch of the mounting plate, it contacts the ground or support surface, raising the base 100 in the height direction. By adjusting the four adjusting components individually, the height of the four corners of the base 100 can be adjusted, thereby achieving alignment between the tool magazine and the machine tool spindle.

[0068] After adjustment, the base 100 is fixedly connected to the machine tool bed (or foundation) by fastener 800 to lock the position of the base 100.

[0069] Furthermore, an annular protrusion is provided at the lower part of the mounting hole of the adjusting block 610 to limit the downward movement of the adjusting member 640; when the lower end of the adjusting member 640 abuts against the annular protrusion, both the support wheel 630 and the adjusting member 640 are located above the lower end face of the base 100. At this time, the support wheel 630 is in a retracted state and does not have a supporting function.

[0070] It should be noted that when the support wheel 630 extends fully downwards from the mounting notch of the mounting plate, the support wheel 630 can be used as a traveling wheel to enable the overall movement of the tool magazine, facilitating assembly and position adjustment.

[0071] It should be noted that in existing technologies, aligning the tool magazine with the machine tool spindle is difficult, resulting in low assembly efficiency. Furthermore, long-term operation can lead to positional shifts due to vibration or foundation settlement, affecting tool changing accuracy. In contrast, this embodiment uses four adjustment components to adjust the height of the four corners of the base 100, enabling adjustment of the tool magazine height and ensuring rapid alignment between the tool magazine and the spindle. Simultaneously, after adjustment, the position is locked by the fixing component 800, effectively preventing positional shifts after long-term operation. In addition, the support wheel 630 serves as both a support element during adjustment and a traveling wheel, featuring a compact structure, convenient operation, simplified tool magazine assembly process, reduced assembly difficulty, improved assembly efficiency and accuracy, and ensured overall operational reliability of the assembled tool magazine.

[0072] In one embodiment of the present invention, the tool magazine adopts a compact, enclosed structure. Specifically, multiple reinforcing ribs are added to the connection between the base 100 and the supporting outer ring 410 of the gear disc component 400 to improve the overall structural rigidity of the tool magazine. Simultaneously, this enclosed structure effectively prevents external dust and chips from entering the space inside the base 100 that houses the transmission gear 320, bearing assembly, and transmission shaft 310, protecting the internal precision components from contamination.

[0073] A second aspect of the present invention provides a vertical five-axis machine tool, which includes the tool magazine for a vertical five-axis machine tool provided in any of the above embodiments.

[0074] Optionally, the machine tool includes a machine tool body, a spindle assembly, and a tool magazine for a vertical five-axis machine tool as provided in any of the above embodiments, wherein the tool magazine is fixedly installed on the machine tool body and cooperates with the spindle assembly to complete the tool change at the tool changing position of the spindle.

[0075] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
