[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The following is combined with Figures 1 to 3 This invention describes a tool transfer mechanism for a multi-layer tool magazine. The multi-layer tool magazine includes at least two parallel tool magazine units 1, with the distribution direction of each tool magazine unit 1 being a reference direction. In a specific embodiment, the multiple tool magazine units 1 can be distributed at intervals along the vertical direction or at intervals along the horizontal direction.

[0025] like Figure 1 As shown, multiple tool magazine units 1 are distributed at intervals, with the reference direction as follows: Figure 1 The direction indicated by m.

[0026] like Figures 1 to 3 As shown, the tool transfer mechanism for a multi-layer tool magazine provided in this embodiment of the present invention includes a moving component, a clamping component 4, and a picking component.

[0027] Specifically, the moving component includes a fixed frame 2 and a moving unit, which is mounted on the tool magazine rack of the tool magazine unit 1 via the fixed frame 2. The moving unit includes at least a moving base 3, which is capable of reciprocating along a reference direction so that it can be moved to correspond to any one of the tool magazine units 1.

[0028] The pickup assembly is located on the movable base 3. The pickup assembly includes at least a pickup base 6. The pickup base 6 is capable of reciprocating. When the pickup base 6 moves relative to the movable base 3, it can move closer to or further away from the multi-layer tool magazine.

[0029] The clamping assembly 4 is disposed on the pickup seat 6, and the clamping assembly 4 can move closer to or further away from the multi-layer tool magazine synchronously with the pickup seat 6. The clamping assembly 4 is used to clamp the clamped part.

[0030] The clamped component includes a cutting tool or a tool holder 5. The tool magazine unit 1 has a tool holder 5 and a tool support 16, with the tool holder 5 detachably connected to the cutting tool. In a detachable configuration, the clamping assembly 4 can either hold the tool holder 5 or the cutting tool. In a non-detachable configuration, the clamping assembly 4 can hold the cutting tool, depending on the specific structure of the tool magazine unit 1.

[0031] With this configuration, the tool transfer mechanism for multi-layer tool magazines provided in this embodiment is directly mounted on the tool magazine rack of the multi-layer tool magazine, resulting in a compact structure and reduced space occupation. Moreover, it only requires the clamping component 4 to move along the distribution direction of the tool magazine unit 1 and along the direction of approaching or moving away from the multi-layer tool magazine, resulting in a small operating space. This helps to reduce the space occupied by the machine tool and solves the problem in the related art that the tool preparation mechanism for multi-layer tool magazines has a large operating space, which leads to a large space occupied by the machine tool.

[0032] In this embodiment of the invention, the moving unit further includes a mounting base 7 and a moving drive component.

[0033] In each tool magazine unit 1 of the multi-layer tool magazine, the tool magazine racks of the two outermost tool magazine units 1 are fixedly mounted with mounting brackets 2. The axis of the mounting base 7 is parallel to the reference direction, and the mounting base 7 extends from one of the mounting brackets 2 to the other mounting bracket 2. Both ends of the mounting base 7 are fixed to the mounting brackets 2, and the mounting base 7 serves as a support for the moving unit.

[0034] The movable base 3 is slidably connected to the mounting base 7, and the sliding direction of the movable base 3 relative to the mounting base 7 is parallel to the reference direction. By reciprocating the sliding of the movable base 3 relative to the mounting base 7, the position of the movable base 3 can be adjusted, thereby adjusting the correspondence between the clamping assembly 4 and each tool magazine unit 1. The position of the movable base 3 relative to the mounting base 7 can be adjusted according to the position of the tool magazine unit 1 where the tool to be retrieved is located.

[0035] The moving drive is used to drive the moving seat 3 to reciprocate relative to the mounting seat 7, providing power for the movement of the moving seat 3 relative to the mounting seat 7.

[0036] The moving drive component can be configured as a gear and rack transmission structure driven by a motor, or a lead screw and nut transmission structure driven by a motor; the specific configuration is not limited.

[0037] Reference Figure 1 and Figure 2 The moving drive component is a gear and rack transmission structure driven by a motor. The rack 19 in the gear and rack transmission structure is fixedly set on the mounting base 7. The gear in the gear and rack transmission structure is rotatably set on the moving base 3 around its own axis. The motor is set on the moving base 3, and the output shaft of the motor is connected to the gear transmission.

[0038] A guide structure is provided between the mounting base 7 and the movable base 3 to guide the movement of the movable base 3.

[0039] The movable seat 3 has a waiting position, a tool changing position, and at least two pick-up positions, each pick-up position corresponding to a tool magazine unit 1. When tool picking and transfer is not required, the tool transfer mechanism for multi-layer tool magazines in this embodiment is in standby mode, and the movable seat 3 is located in the waiting position. When a tool needs to be picked up, the movable seat 3 moves to the pick-up position corresponding to the tool to be picked up. After picking up the tool, the movable seat 3 needs to move to the tool changing position to cooperate with the tool changing mechanism for tool changing. After the tool changing is completed, the movable seat 3 also needs to move to a specific pick-up position to place the removed tool into the corresponding tool magazine unit 1.

[0040] In other words, the tool transfer mechanism for multi-layer tool magazines in this embodiment can clamp the tool and cooperate with the tool changing mechanism to complete the tool change. Compared to the prior art which uses a dedicated support mechanism, requiring the tool to be fixed to the support mechanism before the tool changing mechanism grabs the tool from the support mechanism, this embodiment avoids the need for a support mechanism, further simplifying the machine tool structure and improving its compactness. Furthermore, it can shorten the tool changing time.

[0041] In a further embodiment, the moving component also includes a locking unit, which is disposed at the tool change position and between the mounting base 7 and the moving base 3.

[0042] The locking unit can switch between the unlocked state and the locked state. When the locking unit is switched to the unlocked state, the moving base 3 can reciprocate relative to the mounting base 7, allowing the moving base 3 to move between the waiting position, the tool change position and each pick-up position.

[0043] When the movable seat 3 moves to the tool changing position, the locking unit switches to the locking state. The locking unit can restrict the movement of the movable seat 3 relative to the mounting seat 7, so that the movable seat 3 is fixed in the tool changing position and the position of the movable seat 3 is stable. This can avoid the impact of tool changing impact during the tool changing process on the position accuracy of the movable seat 3.

[0044] In this embodiment, the locking unit includes a locking block 8, a locking shaft, and a locking drive component 9.

[0045] The locking block 8 is disposed on the movable base 3, and the locking block 8 is provided with a locking hole. The locking shaft is disposed on the mounting base 7, which is capable of reciprocating along the axial direction of the locking hole.

[0046] The locking shaft can move between the locked position and the unlocked position. When the locking shaft moves to the locked position, it extends into the locking hole. Through the interaction between the locking shaft and the locking hole, the movement of the movable seat 3 relative to the mounting seat 7 can be restricted.

[0047] When the locking shaft moves to the unlocked position, the locking shaft is outside the locking hole. At this time, there is no interaction between the locking shaft and the locking hole, and there is no restriction on the moving seat 3. The moving seat 3 can move relative to the mounting seat 7.

[0048] The locking drive 9 is disposed on the mounting base 7, and the locking drive 9 is used to drive the locking shaft to move between the locked position and the unlocked position.

[0049] Specifically, the locking drive component 9 can be a linear cylinder.

[0050] In this embodiment of the present invention, the pickup component further includes a first transmission unit, a pickup drive 12, and a second transmission unit.

[0051] The first transmission unit includes a first rack section 10 and a first gear section 11 that are connected in a transmission manner. A pickup drive member 12 is disposed on the movable seat 3, and the output end of the pickup drive member 12 is connected in a transmission manner to the first rack section 10.

[0052] The second transmission unit includes a second rack section 13 and a second gear section 14 connected by transmission. The second gear section 14 is coaxially fixed with the first gear section 11 and can rotate synchronously with the first gear section 11. The second rack section 13 extends into the multi-layer tool magazine, and the pickup seat 6 is fixed relative to the second rack section 13.

[0053] The pickup drive unit 12 inputs power to the first rack part 10 and transmits the power to the second rack part 13 through the first gear part 11 and the second gear part 14, causing the second rack part 13 to move, thereby driving the pickup seat 6 and the clamping assembly 4 to move synchronously.

[0054] In specific embodiments, such as Figure 3 As shown, the extending direction of the first rack portion 10 is perpendicular to the axis of the mounting base 7. The first rack portion 10 is slidably connected to the movable base 3, and the sliding direction of the first rack portion 10 relative to the movable base 3 is parallel to the extending direction of the first rack portion 10. The axis of the first gear portion 11 is parallel to the axis of the mounting base 7, and the first gear portion 11 is rotatably mounted on the movable base 3 about its own axis. The axis of the second gear portion 14 coincides with the axis of the first gear portion 11, and the second gear portion 14 is rotatably connected to the movable base 3. The extending direction of the second rack portion 13 is perpendicular to the extending direction of the first rack portion 10 and the axis of the mounting base 7. The second rack portion 13 is slidably connected to the movable base 3, and the sliding direction of the second rack portion 13 relative to the movable base 3 is parallel to the extending direction of the second rack portion 13. The clamping assembly 4 is disposed on the pickup base 6.

[0055] The aforementioned pickup drive unit 12 may, but is not limited to, use a linear cylinder.

[0056] In a further embodiment, the number of teeth in the first gear section 11 is less than the number of teeth in the second gear section 14. The pickup drive 12 drives the first rack section 10 to move, and after transmission between the first gear section 11 and the second gear section 14, the second rack section 13 moves. The first gear section 11 and the second gear section 14 rotate in the same number of revolutions. Since the number of teeth in the first gear section 11 is less than the number of teeth in the second gear section 14, the movement of the second rack section 13 is greater than the movement of the first rack section 10. This achieves a stroke amplification effect, which helps reduce the driving stroke requirements of the pickup drive 12 and reduces costs.

[0057] In a further embodiment, the pickup assembly further includes a support member 15, which is fixedly disposed on the movable base 3. Along the reference direction, the support member 15 and the clamping portion of the clamping assembly 4 are located on the same side of the pickup base 6.

[0058] The support member 15 is provided with a sliding groove that extends through the support member 15 along the extending direction of the second rack portion 13. The sliding groove is used for the tool holder 5 to enter and reciprocate relative to the support member 15.

[0059] For the tool magazine unit 1, where the tool holder 5 and tool base 16 are separable, the clamping assembly 4 clamps the tool holder 5, separating it from the tool base 16. When the clamping assembly 4 clamps the tool holder 5, the tool holder 5 aligns with the sliding groove. As the clamping assembly 4 moves the tool holder 5 away from the tool base 16, the tool holder 5 can enter the sliding groove. During the movement of the tool holder 5 by the clamping assembly 4, the tool holder 5 can slide within the sliding groove.

[0060] With this configuration, during the process of clamping the tool holder 5 and moving it, one end of the tool holder 5 is clamped by the clamping component 4. At the same time, the support member 15 can support the tool holder 5, reduce the bending moment between the tool holder 5 and the tool, and improve the stability of the tool holder 5 and the tool.

[0061] Furthermore, it should be noted that in this embodiment, by using the clamping assembly 4 to clamp the tool holder 5, the external dimensions of the tool holders 5 in each tool magazine unit 1 can be made consistent. For different tools, only the structural dimensions at the corresponding connection point of the tool holder 5 need to be specifically designed. In this way, the external dimensions of the tool holder 5 are standardized, which in turn facilitates the standardization of the clamping assembly 4, enabling the clamping assembly 4 to adapt to picking up tools from any tool magazine unit 1.

[0062] The clamping assembly 4 can be configured as a structure in which two clamping arms rotate in a cross manner. By controlling the relative rotation of the two clamping arms, the clamping assembly 4 can control the clamping and release of the tool sleeve 5.

[0063] In this embodiment, the tool transfer mechanism for the multi-layer tool magazine further includes a detection component, which includes a first detection unit 17, a second detection unit 18, and a third detection unit.

[0064] The movable seat 3 has a waiting position, and the first detection unit 17 is used to detect the relative position of the movable seat 3 and the waiting position. Specifically, the first detection unit 17 can be a first proximity switch, which is set at the position of the mounting seat 7 corresponding to the waiting position. When the movable seat 3 moves to the waiting position, the first proximity switch is triggered. The waiting position can be regarded as the origin position of the movable seat 3. That is, when the movable seat 3 returns to the origin position, the first proximity switch is triggered, the control system resets the displacement record of the movable seat 3 to zero, realizes the initial position calibration of the movable seat 3, so that the displacement of the movable seat 3 can be remeasured when the movable seat 3 moves again. The measurement of the displacement of the movable seat 3 can be based on the encoder of the motor, which is the moving drive component.

[0065] The second detection unit 18 is used to detect the relative position of the tool holder 5 to be picked up and the clamping assembly 4 on the tool magazine unit 1, so as to determine whether the clamping assembly 4 is driven to the position of the tool holder 5 to be picked up, and to ensure that the clamping assembly 4 can accurately and effectively clamp the tool holder 5. The second detection unit 18 may be, but is not limited to, a second proximity switch or a distance sensor.

[0066] The third detection unit is used to detect whether the clamping assembly 4 is properly clamping the tool to ensure that the tool holder 5 is effectively clamped by the clamping assembly 4. The third detection unit may be, but is not limited to, a third proximity switch or a pressure sensor.

[0067] In some embodiments, the detection assembly further includes a fourth detection unit for detecting whether the locking shaft is locked in place. The fourth detection unit may be, but is not limited to, a fourth proximity switch, which is disposed inside a linear cylinder serving as the locking drive.

[0068] In this embodiment of the invention, the tool transfer mechanism for a multi-layer tool magazine further includes a limiting component, which comprises a first limiting unit and a second limiting unit. The first limiting unit is used to limit the movement range of the movable seat 3 to prevent the movable seat 3 from slipping off the mounting base 7. The second limiting unit is used to limit the movement range of the pickup seat 6 to prevent the pickup seat 6 from slipping off the movable seat 3.

[0069] Both the first and second limiting units mentioned above can be configured as limiting blocks. The limiting blocks are fixed by shock-absorbing pads to reduce vibration.

[0070] The working process of the tool transfer mechanism for a multi-layer tool magazine is described below with reference to the above embodiments.

[0071] In this embodiment, the tool transfer mechanism for a multi-layer tool magazine, upon receiving a tool retrieval command, drives the moving seat 3 from the waiting position to the pickup position corresponding to the tool to be retrieved. The pickup drive then drives the pickup seat 6 to bring the clamping assembly 4 closer to the tool to be retrieved, and the clamping assembly 4 clamps the tool holder 5 corresponding to the tool. After the tool holder 5 separates from the tool holder 16, the moving drive drives the moving seat 3 to move towards the tool change position, and the locking drive 9 drives the locking shaft into the locking hole, fixing the position of the moving seat 3 to await tool change.

[0072] In this embodiment, the tool transfer mechanism for a multi-layer tool magazine, upon receiving a tool loading command, triggers the locking drive 9 to move the locking shaft outside the locking hole, releasing the restriction on the moving seat 3. The moving drive then moves the moving seat 3 from the tool changing position to the pickup position corresponding to the tool to be loaded. The pickup drive then drives the pickup seat 6 to move the clamping assembly 4 closer to the tool holder 16 corresponding to the tool to be loaded. After the tool is installed onto the tool holder 16, the clamping assembly 4 releases the tool, and the pickup drive 12 drives the pickup seat 6 to move the clamping assembly 4 away from the tool magazine unit 1, thus completing the tool loading.

[0073] After tool loading is complete, if there is no need to pick up the next tool, the moving drive can move the moving seat 3 to the waiting position. If it is necessary to pick up the next tool, the tool retrieval steps described above can be performed.

[0074] In summary, the tool transfer mechanism for multi-layer tool magazines provided in this embodiment is integrated with the multi-layer tool magazine, featuring simple and reliable operation, a compact structure, and effectively reduced space occupation on machine tools. Furthermore, the locking unit effectively transmits external force to the base components, ensuring their service life, and is cost-effective and easy to maintain.

[0075] The tool transfer mechanism for multi-layer tool magazines provided in this embodiment can directly cooperate with the tool changing mechanism to achieve tool exchange, effectively reducing the overall tool changing time of the tool magazine, shortening the non-machining time of the machine tool, and improving the efficiency utilization of the machine tool. Furthermore, it can reduce the need for intermediate tool exchange mechanisms, thereby reducing overall manufacturing costs.

[0076] The tool transfer mechanism for multi-layer tool magazines provided in this embodiment has a wide range of applications and can meet the different application states of tool changing methods for vertical and horizontal machine tools. The installation and fixing position can be flexibly adjusted according to the needs of the overall layout of the machine tool, so as to achieve the optimized design of the overall layout of the machine tool.

[0077] This embodiment also achieves standardized design of the tool holder 5 and clamping assembly 4, realizes the transfer of different types of tool holders, reduces the types of structures, reduces production and inventory pressure, and the parts structure is simple, the adaptation and adjustment cost is low, and the cycle is stable and controllable.

[0078] On the other hand, this utility model embodiment also provides a machine tool, including the tool transfer mechanism for a multi-layer tool magazine provided in any of the above embodiments. It has the advantages of compact structure and small space occupation. The derivation process of the beneficial effects of the machine tool in this utility model embodiment is largely similar to the derivation process of the beneficial effects of the tool transfer mechanism for a multi-layer tool magazine described above, and therefore will not be repeated here.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
