Description

Technical Field

[0001] This invention relates to the field of machine tool magazine technology, and more particularly to a hybrid extended tool magazine. Background Technology

[0002] In the process of modern manufacturing upgrading towards intelligence and integration, machine tools, as core processing equipment, are rapidly expanding their application scenarios from traditional standardized processing to personalized and multi-process integration. The mass production of complex structural parts or components places higher demands on the tool storage capacity and tool changing flexibility of machine tools. As a key component for achieving automatic switching between multiple tools, the tool magazine's performance directly determines the machine tool's processing efficiency and process adaptability. Therefore, developing large-capacity, easily expandable tool magazine systems has become one of the core directions for technological upgrading in the industry.

[0003] Current tool magazine expansion solutions on the market have significant technical limitations, mainly focusing on two major pain points: limited expansion methods and poor spatial adaptability. Existing tool magazine expansion methods can only achieve single-dimensional extension, specifically falling into two categories: column expansion, which increases the number of tool magazine columns along the direction perpendicular to the machine tool spindle, expanding storage capacity through horizontal splicing; and row expansion, which increases the number of tool magazine rows along the direction parallel to the machine tool table, increasing the number of tools through vertical extension. In scenarios with large-capacity tool storage, using only column expansion requires a large amount of horizontal installation space, making it difficult to adapt to small and medium-sized workshops or sites with densely packed multiple devices; using only row expansion increases the vertical depth of the tool magazine, which may not only cause spatial interference with auxiliary equipment around the machine tool but also lengthen the tool transfer path and reduce tool change response speed. Summary of the Invention

[0004] This invention provides a hybrid expansion tool magazine to address the shortcomings of existing tool magazines, such as limited expansion options and poor spatial adaptability. It develops a tool magazine system that can achieve multi-dimensional hybrid expansion, flexible cross-compartment tool scheduling, and adaptability to limited installation space.

[0005] This invention provides a hybrid extended tool magazine, comprising: Multiple tool magazine units, tool magazine connection device, moving mechanism, tool pushing device and tool changing device; Multiple tool magazine units are fixedly connected by the tool magazine connecting device to form a unified frame configuration. The tool changing device is fixed to one of the tool magazine units. The mixed-connected extended tool magazine is formed by the tool magazine units close to the tool changing device expanding inward according to a preset column spacing and expanding backward according to a preset row spacing. Each tool magazine unit is provided with multiple detachable tool sleeves. The moving mechanism is provided between every two rows of the tool magazine units. The moving mechanism is used to clamp the tool sleeve and move it along the column direction. Each tool magazine unit is provided with a pusher device behind its reference point. The pusher device is used to provide the directional movement power for the tool holder to change between the reference point of the tool magazine unit and the tool holder changing position of the moving mechanism.

[0006] According to a hybrid extended tool magazine provided by the present invention, the moving mechanism is side-mounted on the tool magazine connecting device via a guide rail. The moving mechanism includes a driving component and a tool holder clamping device. The moving mechanism moves along the column direction under the action of the driving component. The tool holder clamping device includes a clamping space with a C-shaped opening. The clamping space is provided with a guide channel for the movement of the tool holder in the row direction.

[0007] According to the present invention, a hybrid extended tool magazine includes a tool holder clamping device comprising support plates arranged vertically opposite each other, and a moving mechanism further comprising a locking device disposed on the upper support plate. The locking device comprises a locking cylinder, a conical positioning pin, a guide rod, and a connecting plate. The upper end face of the piston rod of the locking cylinder is fixed to the guide rod via the connecting plate. The guide rod has a double-column structure, and the conical positioning pin is disposed on the lower end face of the guide rod. When the locking cylinder moves, it drives the guide rod and the conical positioning pin to move, thereby locking or releasing the tool holder.

[0008] According to the present invention, a hybrid extended tool magazine has two elongated clamping plates arranged opposite to each other on the inner surfaces of the two support plates, and a guide channel is formed between the two clamping plates. The end of the tool sleeve used for clamping is provided with a flat part for abutting and cooperating with the plane of the clamping plate.

[0009] According to the present invention, a hybrid extended tool magazine includes a tool pushing device comprising a tool pushing cylinder, a slide rail, a tool pushing block, and a connecting flange. The tool pushing cylinder is fixed to the back of the tool magazine unit via the connecting flange. The piston cylinder of the tool pushing cylinder is fixed to the slide rail by screws. The tool pushing block is fixed to the front end face of the slide rail.

[0010] According to a hybrid extended tool magazine provided by the present invention, the moving mechanism and the tool pushing device are configured to cooperate to realize the tool sleeve exchange between tool magazine units in the same row, between tool magazine units in the same row, or between cross tool magazine units.

[0011] According to a hybrid extended tool magazine provided by the present invention, the tool changing device is fixed to the tool magazine unit by its welded bracket, and the tool changing device remains fixed at all times.

[0012] According to the present invention, a hybrid extended tool magazine is provided, wherein the tool magazine connecting device includes a top connecting plate, a side connecting plate and a rear connecting plate. The tops of the tool magazine units in the same column are connected by the top connecting plate, the sides of the tool magazine units in the same column are connected by the side connecting plate, and the rear sides of two adjacent tool magazine units in the same row are connected by the rear connecting plate.

[0013] According to the present invention, a hybrid extended tool magazine further includes a support device, the support device including a base plate and a T-shaped bracket, the upper end of the T-shaped bracket being connected to the lower end of the tool magazine unit, the lower end of the T-shaped bracket being connected to the base plate, and the height of the T-shaped bracket on the base plate being adjustable.

[0014] According to a hybrid extended tool magazine provided by the present invention, the T-shaped bracket includes a horizontal plate extending along the column direction and a plurality of spaced vertical plates extending upward from the horizontal plate, wherein the distance between two adjacent vertical plates is adjustable. The base plate has multiple mounting holes distributed along the row direction. The lower end of the T-shaped bracket is connected to the mounting holes by bolts. The distance between two adjacent rows of the tool magazine units can be adjusted by adjusting the position of the mounting holes corresponding to the T-shaped bracket.

[0015] The hybrid expansion tool magazine provided by this invention increases tool storage capacity by forming a hybrid configuration including column and row expansions. The expansion dimensions and density can be flexibly adjusted according to the actual size of the installation space, adapting to diverse installation scenarios and avoiding spatial interference problems caused by unidirectional extension. Simultaneously, multiple tool magazine units form a unified frame configuration through a tool magazine connection device, eliminating the need for additional redundant installation space. Compared to traditional distributed tool magazines, space utilization is effectively improved, making it suitable for complex site requirements such as small and medium-sized workshops and densely packed multi-equipment layouts. The tool magazine adopts a modular design, allowing tool magazine units to be added or removed independently. The tool holders are detachable, and the tool magazine connection device can accommodate combinations of tool magazine units with different expansion dimensions without requiring destructive modifications such as cutting or welding to the original frame. When tool storage capacity needs to be increased, only a new tool magazine unit needs to be added and fixed to the original frame through the tool magazine connection device. Simultaneously, a moving mechanism and a pusher device can complete the expansion, shortening the expansion cycle. The unified frame configuration, through the rigid connection of the tool magazine connection device, greatly enhances the overall structural strength of the tool magazine. The detachable tool sleeve, independently arranged moving mechanism and pusher device facilitate individual disassembly and maintenance. There is no need to stop the machine to disassemble the entire tool magazine. Only the corresponding parts need to be replaced to restore operation. The maintenance time is shortened, reducing equipment operation and maintenance costs and downtime losses. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] In the description of this invention, it should be understood that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention.

[0027] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0029] like Figures 1 to 7 As shown, the present invention provides a hybrid extended tool magazine, comprising: Multiple tool magazine units 10, tool magazine connecting device, moving mechanism 11, tool pushing device 12, and tool changing device 13; Multiple tool magazine units 10 are fixedly connected by the tool magazine connecting device to form a unified frame configuration. The tool changing device 13 is fixed to one of the tool magazine units 10. The mixed-connected extended tool magazine is formed by the tool magazine units 10 near the tool changing device 13 expanding inwards according to a preset column spacing and expanding backwards according to a preset row spacing. Each tool magazine unit 10 is provided with multiple detachable tool sleeves 20. The moving mechanism 11 is provided between every two rows of the tool magazine units 10. The moving mechanism 11 is used to clamp the tool sleeve 20 and move it along the column direction. Each tool magazine unit 10 is provided with a pusher device 12 behind the reference point. The pusher device 12 is used to provide the directional movement power for the tool holder 20 to change between the reference point of the tool magazine unit 10 and the tool holder 20 changing position of the moving mechanism 11.

[0030] Specifically, Figure 1 and Figure 2 The diagram illustrates a tool magazine expansion configuration: it includes seven tool magazine units 10 arranged in three rows. The first row is closest to the tool changer 13, extending inwards to form the second and third rows. The first row has only one tool magazine unit 10, while the second and third rows each have three tool magazine units 10. The first row is closest to the tool changer 13, extending backwards to form the second and third rows. Each tool magazine unit 10 has a racetrack-shaped configuration, with multiple tool sleeves 20 evenly distributed on its left and right sides. The tool sleeves 20 can move up and down via their own transmission mechanism.

[0031] Through the coordinated action of the moving mechanism 11 and the pusher device 12, the tool holders 20 can be exchanged in all dimensions between tool magazine units 10 in the same row, column, and cross (different rows and columns). No manual intervention or batch adjustment of the tool magazine layout is required. By conveying along the column direction with the moving mechanism 11 and pushing along the row direction with the pusher device 12, the target tool holder 20 can be precisely scheduled to the tool magazine unit 10 fixed with the tool changing device 13. This meets the needs of multi-tool rapid switching for complex processes such as milling, drilling, and tapping, reduces downtime caused by tool scheduling, and improves processing efficiency.

[0032] The tool changing device 13 can automatically exchange the tool and the spindle tool at the tool changing point in the tool magazine. The tool changing device 13 is fixed to the tool magazine unit 10 by its welded bracket 131. Figure 1 In the example, the tool changing device 13 is fixed to the tool magazine unit 1-1 (i.e., the tool magazine unit in the first row of the first column). The position of the tool changing device 13 remains fixed, and there is no need to frequently adjust its position due to the expansion of the tool magazine (extension in the row / column direction), which ensures the long-term stability of tool changing accuracy and reduces machining errors.

[0033] In a preferred embodiment of the present invention, the moving mechanism 11 is mounted on the tool magazine connecting device via a guide rail. The moving mechanism 11 includes a driving component and a tool sleeve clamping device. The moving mechanism 11 moves along the column direction under the action of the driving component. The tool sleeve clamping device includes a clamping space with a C-shaped opening. The clamping space is provided with a guide channel for the row movement of the tool sleeve 20.

[0034] The moving mechanism 11 adopts a side-mounted design, which compresses the spatial layout of the moving mechanism 11, the tool magazine unit 10, and the pusher device 12 into a compact and coordinated state. Compared with the traditional installation method, the overall lateral space occupied by the tool magazine is effectively reduced, further adapting to the equipment requirements of limited installation space, and is especially suitable for scenarios with dense expansion of multiple tool magazines. The tool holder clamping device adopts a C-shaped opening structure design, which can realize the lateral entry and exit of the tool holder 20 without the need for complex axial alignment operations of the tool holder 20. When the pusher device 12 pushes the tool holder 20 into the clamping space, the opening structure can accommodate the lateral entry of tool holders 20 of different sizes, improving adaptability and avoiding the jamming problem caused by the size difference of the tool holder 20 in the traditional clamping structure. The C-shaped opening makes it easy for operators to intuitively observe the clamping status of the tool holder 20. When the tool holder 20 is offset or the clamping is loose, it can be quickly adjusted through the opening without disassembling the clamping device, greatly improving the convenience of maintenance and reducing downtime caused by clamping failure.

[0035] like Figures 4 to 6 As shown, the moving mechanism 11 includes an L-shaped mounting plate 111. The driving components include, for example, a motor 112, a gear 113, and a rack and pinion 114 transmission structure. The motor 112 is fixed to the side of the mounting plate 111, and the motor 112 enables the moving mechanism 11 to move in the column direction through the gear 113 and rack and pinion 114 transmission structure. Of course, the transmission structure is not limited to the gear 113 and rack and pinion 114 mating structure; for example, it can also be a ball screw structure, etc.

[0036] In one embodiment, the blade holder clamping device includes support plates 115 arranged vertically opposite each other, and the moving mechanism 11 further includes a locking device. The locking device is disposed on the upper support plate 115 and includes a locking cylinder 116, a conical positioning pin 117, a guide rod 118, and a connecting plate 119. The upper end face of the piston rod of the locking cylinder 116 is fixed to the guide rod 118 through the connecting plate 119. The guide rod 118 has a double-column structure, and the conical positioning pin 117 is disposed on the lower end face of the guide rod 118. When the locking cylinder 116 moves, it drives the guide rod 118 and the conical positioning pin 117 to move, thereby locking or releasing the blade holder 20.

[0037] While the clamping structure holds the tool holder 20, the locking device further limits and locks the tool holder 20, enhancing locking reliability and ensuring the stability of the tool holder 20 during scheduling. The tapered positioning pin 117, for example, can cooperate with the positioning hole on the tool holder 20 to limit its position. The tapered structure has a self-centering function, enabling rapid alignment and improving positioning efficiency. The guide rod 118 adopts a double-column structure, which can simultaneously constrain the movement trajectory of the locking cylinder 116 from both sides, ensuring that the tapered positioning pin 117 always moves along a preset vertical path, accurately aligning with the positioning hole of the tool holder 20, and preventing positioning misalignment or locking failure due to guide deviation.

[0038] Furthermore, the inner surfaces of the two support plates 115 are provided with two elongated clamping plates 120 arranged opposite each other, forming the guide channel between the two clamping plates 120. The end of the blade sleeve 20 used for clamping has a flat part for abutting against the plane of the clamping plate 120. By providing a flat part on the cylindrical blade sleeve 20, it can adapt to and abut against the planar structure of the clamping plate 120, which helps to improve the clamping stability and reliability, and avoids the blade sleeve 20 being difficult to clamp or easily slipping out. The distance between the two clamping plates 120 can be slightly larger than the radial distance of the clamping position of the blade sleeve 20, which facilitates the entry and exit of the blade sleeve 20 into the clamping area. With the help of the locking device, the blade sleeve 20 is limited to ensure that it remains stable during movement.

[0039] In a preferred embodiment of the present invention, the pusher device 12 includes a pusher cylinder 121, a slide rail 122, a pusher block 123, and a connecting flange 124. The pusher cylinder 121 is fixed to the back of the tool magazine unit 10 via the connecting flange 124. The piston cylinder of the pusher cylinder 121 is fixed to the slide rail 122 with screws, and the pusher block 123 is fixed to the front end face of the slide rail 122. Figure 7 As shown, the tool magazine unit 10 is provided with a tool sleeve 20 clamping part. The tool sleeve 20 is pushed out and retracted by the extension and retraction of the piston rod of the pusher cylinder 121 in conjunction with the pusher block 123.

[0040] In a preferred embodiment of the present invention, the tool magazine connecting device includes a top connecting plate 14, a side connecting plate 15, and a rear connecting plate 16. The tops of the tool magazine units 10 in the same column are connected by the top connecting plate 14, the sides of the tool magazine units 10 in the same column are connected by the side connecting plates 15, and the rear sides of two adjacent tool magazine units 10 in the same row are connected by the rear connecting plate 16. Through the synergistic action of the three types of connecting plates and the fastening with screws, multiple independent tool magazine units can form a rigid integrated frame, improving the overall torsional strength and avoiding tool sleeve 20 jamming or tool changing accuracy deviation caused by structural deformation, thus ensuring the long-term stable operation of the tool magazine.

[0041] like Figure 3As shown, in order to further improve the structural strength of the tool magazine, side connecting plates 15 are provided on both the left and right sides of the same row of tool magazine units 10, and a rear connecting plate 16 is also provided on the back of each tool magazine unit 10. The rear connecting plate 16 is connected to the two side connecting plates 15 to form a frame structure. Multiple frame structures can be arranged at intervals along the height direction of the tool magazine unit 10.

[0042] In a preferred embodiment of the present invention, the hybrid extended tool magazine further includes a support device, which includes a base plate 17 and a T-shaped bracket 18. The upper end of the T-shaped bracket 18 is connected to the lower end of the tool magazine unit 10, and the lower end of the T-shaped bracket 18 is connected to the base plate 17. The height of the T-shaped bracket 18 on the base plate 17 is adjustable.

[0043] For scenarios where the workshop floor has slight slopes or local bumps / dimples, the height of the corresponding T-shaped brackets 18 can be adjusted individually (e.g., by raising or lowering bolts, adding or removing shims) to ensure that the bottom of all tool magazine units 10 is on the same horizontal plane. This prevents the tool magazine from tilting due to uneven ground and eliminates jamming or displacement of the tool holders 20 during tool changing. When the tool magazine needs to be used with machine tools of different heights, there is no need to replace the entire support system. Only the height of the T-shaped brackets 18 needs to be adjusted to match the height difference between the machine tool spindle and the tool magazine changing position, improving adaptability and reducing the customization costs of support systems due to differences in machine tool models.

[0044] Furthermore, the T-shaped bracket 18 includes a horizontal plate 181 extending along the column direction and a plurality of spaced vertical plates 182 extending upward from the horizontal plate 181. The upper end of the vertical plate 182 is used to connect to the tool magazine unit 10, and the distance between two adjacent vertical plates 182 is adjustable. By adjusting the distance between two adjacent vertical plates 182, the row spacing of the tool magazine unit 10 can be adjusted. That is, the multi-row tool magazine units 10 can be arranged with equal row spacing, or different row spacings can be set according to actual needs to meet space utilization requirements or match tools of different sizes, thereby improving storage compatibility.

[0045] The base plate 17 is provided with multiple mounting holes distributed along the row direction (not shown in the figure). The lower end of the T-shaped bracket 18 is connected to the mounting holes by bolts. The distance between two adjacent rows of tool magazine units 10 can be adjusted by adjusting the position of the mounting holes corresponding to the T-shaped bracket 18. Thus, the column spacing between adjacent rows of tool magazine units 10 can be adjusted. That is, multiple rows of tool magazine units 10 can be arranged with equal column spacing, or different column spacing can be set according to actual needs.

[0046] The hybrid expansion tool magazine provided by this invention increases tool storage capacity by forming a hybrid configuration including column and row expansion. The expansion dimensions and density can be flexibly adjusted according to the actual size of the installation space, adapting to diverse installation scenarios and avoiding spatial interference problems caused by unidirectional extension. Simultaneously, multiple tool magazine units 10 form a unified frame configuration through a tool magazine connection device, eliminating the need for additional redundant installation space. Compared to traditional distributed tool magazines, space utilization is effectively improved, making it suitable for complex site requirements such as small and medium-sized workshops and densely packed multi-equipment layouts. The tool magazine adopts a modular design, allowing tool magazine units 10 to be added or removed independently. The tool holders 20 are detachable, and the tool magazine connection device can accommodate combinations of tool magazine units 10 with different expansion dimensions without requiring destructive modifications such as cutting or welding to the original frame. When increasing tool storage capacity is required, only a new tool magazine unit 10 needs to be added and fixed to the original frame through the tool magazine connection device. Simultaneously, the expansion can be completed with the moving mechanism 11 and the pusher device 12, which helps to shorten the expansion cycle. The unified frame configuration, through the rigid connection of the tool magazine connecting device, greatly enhances the overall structural strength of the tool magazine. The detachable tool sleeve 20, the independently arranged moving mechanism 11 and the pusher device 12 are easy to disassemble and maintain individually. There is no need to stop the machine to disassemble the entire tool magazine. Only the corresponding parts need to be replaced to restore operation. The maintenance time is shortened, and the equipment operation and maintenance costs and downtime losses are reduced.

[0047] The tool magazine of this invention can be expanded in either row or column direction according to the machine tool space, achieving modular and universal design requirements. It can also be expanded in a mixed row and column manner, enhancing flexibility and tool magazine adaptability, and providing customers with more form factor options. The tool magazine can realize tool holder exchange between tool magazine units in the same row, between tool magazine units in the same row, or between cross tool magazine units. The tool holder exchange process can be understood with reference to the following embodiment. Figure 2 As shown, the tool magazine unit is equipped with a pusher device at the corresponding positions of the left and right reference points. A moving mechanism is provided between every two rows of tool magazine units. The tool sleeve can be exchanged between any tool magazine units by cooperating with the pusher device through the moving mechanism.

[0048] Example 1: Tool holder exchange between tool magazine units in the same row: Tool holders are exchanged between tool magazine units 2-1 (i.e., the first row of the second column) and 2-3 (i.e., the third row of the second column). Initially, the tool holder to be exchanged in tool magazine unit 2-1 is at the right reference point of the tool magazine. The right-side pusher pushes the tool holder out. The moving mechanism moves to the tool holder changing position of tool magazine unit 2-1, where the tool holder clamping device clamps the tool holder. The moving mechanism moves forward until the tool holder is completely disengaged from the pusher block of the pusher device. At this time, the pusher device of the tool holder in tool magazine unit 2-3 is disengaged. The moving mechanism moves backward to the tool holder changing position of tool magazine unit 2-3. The tool holder clamping device of the moving mechanism releases the tool holder. The moving mechanism moves forward to the initial position, and the pusher device of the tool holder in tool magazine unit 2-3 retracts. At this time, the tool holder to be exchanged is at the right reference point of tool magazine unit 2-3, completing the tool holder exchange between tool magazine units in the same column.

[0049] Example 2: Tool holder exchange between tool magazine units: Tool holders are exchanged in tool magazine units 1-1 (i.e., the first row of the first column) and 3-1 (i.e., the first row of the third column). Initially, the tool holder to be exchanged in tool magazine unit 1-1 is at the left reference point of the tool magazine. The left pusher pushes out the tool holder, and the moving mechanism moves from the initial position to the tool holder changing position in tool magazine unit 1-1. The tool holder clamping device clamps the tool holder and moves forward to completely disengage from the pusher block of the pusher device in tool magazine unit 1-1. The left pusher device of tool magazine unit 1-1 retracts, and the right reference point of tool magazine unit 2-1 is in the empty tool holder position. The right pusher pushes out, and the moving mechanism moves backward to the tool holder changing position in tool magazine unit 2-1. The moving mechanism loads the tool. The clamping device releases the tool sleeve, and the tool pusher of tool magazine unit 2-1 retracts. The tool sleeve is then driven to the left reference point of tool magazine unit 2-1 via its own transmission mechanism. Then, the tool sleeves of tool magazine units 2-1 and 3-1 are exchanged through the inter-row moving mechanism of tool magazine units 2-1 and 3-1 in conjunction with the tool pusher of the left reference point of tool magazine unit 2-1 and the tool pusher of the right reference point of tool magazine unit 3-1. Note that at the initial stage of the tool sleeve exchange between tool magazine units 2-1 and 3-1, the right reference point of tool magazine unit 3-1 is in the empty tool sleeve position. At this time, the tool sleeve to be exchanged has been moved to the right reference point of tool magazine unit 3-1, thus completing the tool sleeve exchange between tool magazine units in the same row.

[0050] Example 3: Cross-row (different rows, different columns) tool holder exchange between tool magazine units: Tool holders are exchanged between tool magazine units 1-1 (i.e., the first row of the first column) and 3-3 (i.e., the third row of the third column). Initially, the tool holder to be exchanged in tool magazine unit 1-1 is at the left reference point of the tool magazine, and the right reference point of tool magazine unit 2-3 is in the empty tool holder position. The tool pusher of tool magazine unit 1-1 pushes out the tool holder. The transfer mechanism between the first and second columns of tool magazine units moves from the initial position to the tool holder exchange position of tool magazine unit 1-1. The tool holder clamping device clamps the tool holder and moves forward to completely disengage from the pusher block of the tool pusher of tool magazine unit 1-1. The empty tool holder position of the left pusher of tool magazine unit 1-1 retracts. At this time, the empty tool holder of the pusher of tool magazine unit 2-3 pushes out. The moving mechanism moves backward to the tool holder exchange position of tool magazine unit 2-3. The tool holder clamping device releases. -3 The pusher retracts, the moving mechanism moves to the initial position, and the tool sleeve is driven to the left reference point of the tool magazine unit 2-3 through its own transmission mechanism. The moving mechanism between the tool magazine units 2-3 and 3-3 moves backward from the initial position to the tool sleeve changing position of the tool magazine unit 2-3. The tool sleeve clamping device clamps the tool sleeve and moves forward to completely disengage from the pusher block of the pusher device of the tool magazine unit 2-3. The empty tool sleeve of the pusher device of the tool magazine unit 2-3 retracts, and the empty tool sleeve position of the right reference point of the tool magazine unit 3-3 is pushed out. The transfer mechanism moves to the tool sleeve changing position of the tool magazine unit 3-3.
