Description

Technical Field

[0001] This utility model relates to the field of tool magazine technology, and in particular to a single-tool magazine chain-type tool magazine. Background Technology

[0002] Based on the provided technical description, the existing tool magazine technology mainly suffers from the following technical pain points:

[0003] I. The problem of insufficient machine tool adaptability due to the generalization design: Traditional standardized tool magazines cannot adapt to the geometric differences of the tilting head of different machine tools in the X / Y axis directions. This results in the tool change point position in the X axis direction not being able to accurately match the structure of different machine tools. The difference in the spindle center offset in the Y axis direction leads to tool positioning errors, requiring complex mechanical compensation devices or manual adjustments, which reduces tool change accuracy and efficiency.

[0004] II. Defects in scalability caused by rigid structure: Existing tool magazines generally adopt a fixed-capacity integrated tool magazine design, which means that the tool capacity cannot be flexibly expanded according to processing needs (e.g., more than 40 tools). When adding or removing tools, the entire single-tool magazine chain must be replaced. In special working conditions, redundant tool positions are forced to be configured, resulting in wasted space. Maintenance and upgrade bottlenecks of non-modular architecture: The lack of modular design concept in traditional tool magazines leads to: the need to redesign the overall mechanical structure when expanding the system capacity; the limitation of adjusting the length of key components (such as lead screws) in the overall layout; maintenance requires stopping the machine to disassemble the entire device, affecting production efficiency; the contradiction between space utilization and functional expansion; the difficulty in balancing the limited installation space and the need for multiple tool storage, the requirement for rapid tool changing and the stability of tool magazine movement; and the need for classified management of special tool groups for multi-process machining.

[0005] This non-standard tool magazine effectively solves the systemic defects of traditional tool magazines in terms of machine tool compatibility, flexible production capacity, and space utilization efficiency through customized adaptation, modular tool magazine, and axially expandable design. It reflects the core requirements of advanced manufacturing equipment for high adaptability, reconfigurability, and scalability. Utility Model Content

[0006] The technical problem to be solved by this utility model is: in order to solve the problem that traditional standardized tool magazines cannot adapt to the geometric differences of the tilting head of different machine tools in the X / Y axis directions, resulting in the inability to accurately match the tool change point position in the X axis direction with different machine tool structures, and the difference in the spindle center offset in the Y axis direction causing tool positioning errors, requiring complex mechanical compensation devices or manual adjustments, which reduces tool change accuracy and efficiency, a single tool magazine chain tool magazine is provided.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a single-tool magazine chain-type tool magazine, including a frame and a tool magazine assembly mounted on the frame. The frame is provided with a chain mechanism for driving the tool magazine assembly to rotate cyclically. The frame is also provided with an automatic tool changing mechanism. A tool transfer mechanism is provided between the tool magazine assembly and the automatic tool changing mechanism. The tool transfer mechanism is used to transfer the tool in the tool magazine assembly to the automatic tool changing mechanism, or to transfer the tool on the automatic tool changing mechanism to the tool magazine assembly.

[0008] The tool transfer mechanism includes a transverse displacement mechanism and a longitudinal displacement mechanism mounted on the transverse displacement mechanism. The longitudinal displacement mechanism is equipped with a gripper mechanism for holding the tool. The transverse displacement mechanism drives the longitudinal displacement mechanism to move along the X-axis, and the longitudinal displacement mechanism drives the gripper mechanism to move along the Y-axis. Compared to existing technologies, this solution, by setting up a tool transfer mechanism between the tool magazine and the automatic tool changer, compensates for non-standard tool magazines and adapts to the geometric differences in the X / Y axes of different machine tool tilting heads. This achieves precise matching of the tool change point position in the X-axis direction to different machine tool structures and compensates for spindle center offset in the Y-axis direction to ensure tool positioning, thereby improving tool change accuracy and efficiency.

[0009] To realize the lateral displacement mechanism, in some preferred embodiments, the lateral displacement mechanism includes a lateral slide plate, which is slidably mounted on a frame along the X-axis direction. A first screw is threadedly connected to the frame, and the lateral slide plate is threadedly connected to the first screw. A lateral motor that is drivenly connected to the first screw is provided on the frame.

[0010] In order to enable the transverse slide to slide on the frame, in some preferred embodiments, the frame is provided with a linear guide rail along the X-axis, and the transverse slide is provided with a slider, which is slidably mounted on the linear guide rail.

[0011] In order to realize the longitudinal displacement mechanism, in some preferred embodiments, the transverse slide is provided with a first detection mechanism for detecting the displacement range of the longitudinal displacement mechanism.

[0012] To ensure that the transverse slide plate slides stably and reliably on the frame, in some preferred embodiments, the first detection mechanism includes a first proximity sensor, which is mounted on the transverse slide plate.

[0013] To realize the longitudinal displacement mechanism, in some preferred embodiments, the longitudinal displacement mechanism includes a longitudinal slide plate, which is slidably mounted on a transverse slide plate along the Y-axis direction. A second screw is threadedly connected to the transverse slide plate, and the longitudinal slide plate is threadedly connected to the second screw. A longitudinal motor that is drivenly connected to the second screw is provided on the transverse slide plate.

[0014] In order to enable the longitudinal slide plate to slide on the transverse slide plate, in some preferred embodiments, a slide rod is provided on the transverse slide plate along the Y-axis direction, and a slide hole matching the slide rod is provided on the longitudinal slide plate, with the slide rod disposed in the slide hole.

[0015] To ensure that the gripper mechanism slides stably and reliably on the longitudinal slide plate, in some preferred embodiments, a second detection mechanism for detecting the displacement range of the gripper mechanism is provided on the longitudinal slide plate.

[0016] To implement the second detection mechanism, in some preferred embodiments, the second detection mechanism includes a second proximity sensor mounted on a longitudinal slide plate.

[0017] The beneficial effects of this utility model are as follows: When using a single-tool magazine chain-type tool magazine, a tool transfer mechanism is set between the tool magazine tool group and the automatic tool changer. The tool transfer mechanism is used to compensate for non-standard tool magazines and adapt to the geometric differences of different machine tool tilting heads in the X / Y axis directions. This achieves precise matching of the tool change point position in the X-axis direction with different machine tool structures and compensates for the spindle center offset in the Y-axis direction to ensure tool positioning, thereby improving tool changing accuracy and efficiency. This avoids the problem that traditional standardized tool magazines cannot adapt to the geometric differences of different machine tool tilting heads in the X / Y axis directions, which leads to the inability to accurately match the tool change point position in the X-axis direction with different machine tool structures, and the difference in spindle center offset in the Y-axis direction causing tool positioning errors. This requires complex mechanical compensation devices or manual adjustments, reducing tool changing accuracy and efficiency. Attached Figure Description

[0031] like Figures 1-7As shown, a single-tool magazine chain-type tool magazine includes a frame 1, a tool magazine assembly 2 fixed on the frame 1, a chain mechanism 3 for driving the tool magazine assembly 2 to rotate cyclically on the frame 1, tools mounted on the tool magazine assembly 2 on the chain mechanism 3, an automatic tool changer 4 on the frame 1, and a tool transfer mechanism 5 between the tool magazine assembly 2 and the automatic tool changer 4. The tool transfer mechanism 5 is used to transfer the middle tool of the tool magazine assembly 2 to the automatic tool changer 4, or to transfer the tool on the automatic tool changer 4 to the tool magazine assembly 2. The automatic tool changer 4 is used to clamp the tool on the tool transfer mechanism 5 onto the spindle of the machine tool.

[0032] The tool transfer mechanism 5 includes a transverse displacement mechanism 6 and a longitudinal displacement mechanism 7 disposed on the transverse displacement mechanism 6. The longitudinal displacement mechanism 7 is provided with a gripper mechanism 8 for gripping the tool. The transverse displacement mechanism 6 is used to drive the longitudinal displacement mechanism 7 to move along the X-axis direction, and the longitudinal displacement mechanism 7 is used to drive the gripper mechanism 8 to move along the Y-axis direction, so that the transverse displacement mechanism 6 drives the longitudinal displacement mechanism 7 to move along the X-axis direction, and the longitudinal displacement mechanism 7 drives the gripper mechanism 8 to move along the Y-axis direction.

[0033] The lateral displacement mechanism 6 includes a lateral slide plate 9, which is slidably mounted on the frame 1 along the X-axis. A first screw 10 is threadedly connected to the frame 1, and the lateral slide plate 9 is threadedly connected to the first screw 10. A lateral motor 11 is provided on the frame 1 and is drivenly connected to the first screw 10. A linear guide rail is provided on the frame 1 along the X-axis, and a slider is provided on the lateral slide plate 9. The slider is slidably mounted on the linear guide rail.

[0034] A first detection mechanism for detecting the displacement range of the longitudinal displacement mechanism 7 is provided on the transverse slide plate 9. The first detection mechanism includes a first proximity sensor 12, which is mounted on the transverse slide plate 9.

[0035] The longitudinal displacement mechanism 7 includes a longitudinal slide plate 13, which is slidably mounted on a transverse slide plate 9 along the Y-axis.

[0036] A second detection mechanism for detecting the displacement range of the gripper mechanism 8 is provided on the longitudinal slide plate 13. The second detection mechanism includes a second proximity sensor 16, which is mounted on the longitudinal slide plate 13.

[0037] In the above-described single-tool magazine chain-type tool magazine, a tool transfer mechanism 5 is installed between the tool magazine assembly 2 and the automatic tool changer 4. A transverse displacement mechanism 6 and a longitudinal displacement mechanism 7 drive the gripper mechanism 8 to move, achieving offset compensation in the X and Y axes. The gripper mechanism 8 clamps the tool holder from the tool magazine assembly 2 onto the tool changer plane, then moves it to the automatic tool changer 4 where the tool arm clamps the tool. The gripper mechanism 8 then retracts to its original position, and the automatic tool changer 4 extends the tool to the spindle tool change point, thus completing the entire tool changing structure. This non-standard tool magazine effectively solves the systemic defects of traditional tool magazines in terms of machine tool compatibility, flexible production capacity, and space utilization efficiency through customized adaptation, modular tool magazines, and axial expandable design. It reflects the core requirements of advanced manufacturing equipment for high adaptability, reconfigurability, and scalability. In addition, each tool magazine in the tool assembly has 40 tools and is made into a module. Several tool magazine modules can be made in parallel. To add tool magazines for different working conditions and tool quantity requirements, only the length of the X-axis lead screw needs to be changed.

Those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification but must be determined according to the claims.
