[0004] The existing tool magazine adopts carousel mode to transfer tool to tool changing position, which is not conducive to transferring multiple tools at a time, and is not suitable for multi-tool head processing equipment. UTILITY MODEL CONTENTS

[0005] In order to overcome the above-mentioned deficiencies of prior art, the utility model provides a circulating tool magazine, which is suitable for replacing multiple tools at a time for multi-tool head processing equipment and has the advantage of high space utilization.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme:

[0007] A circulating tool magazine comprises:

[0008] A main frame body is provided with a pair of storage layers spaced vertically above and below;

[0009] A group of tool holders are provided with a plurality of tool seats for storing tools, and the tool holders are arranged along the x direction on the pair of storage layers and are slidably connected to the storage layers along the x direction;

[0010] A lifting assembly is provided with a pair of transfer seats spaced along the x direction on the moving part of the lifting assembly, and the pair of transfer seats are located outside the two ends of the storage layers in the x direction, and the lifting assembly is used to drive the pair of transfer seats to move up and down to reciprocally align the transfer seats with the pair of storage layers in the longitudinal direction;

[0011] A material moving device is used to drive the group of tool holders to slide on the storage layers to the tool holders at the front end of the sliding direction to be transferred to the transfer seats.

[0012] Further, the circulating tool magazine in the present application is provided with a storage sliding rail extending along the x direction on the storage layer, and the tool holders on the storage layer are slidably connected to the storage sliding rail;

[0013] The transfer seat is provided with a transfer sliding rail extending along the x direction, and the tool holders moved to the transfer seat are slidably connected to the transfer sliding rail.

[0014] Furthermore, a circulating tool magazine in this application also includes a positioning device for locking the tool holder in the x-direction;

[0015] The positioning device includes a movably set positioning element and a positioning driver that is motively connected to the positioning element. The positioning driver is used to drive the positioning element to move so that the positioning element jams the tool holder.

[0016] The positioning device is mounted on the transfer seat, and the positioning devices are arranged in pairs on both sides of the tool holder. As a preferred embodiment of this application, based on the above device, the method of use is as follows: during the material transfer process of the material transfer device, the positioning device unlocks the tool holder; after the material transfer device completes the material transfer action, the positioning device locks the tool holder.

[0017] Furthermore, in a circulating tool magazine of this application, a positioning structure is provided between the positioning member and the tool holder. The positioning structure includes a V-shaped groove and a protrusion that cooperate with each other. As a preferred embodiment of this application, the protrusion and the V-shaped groove can correct the position of the tool holder and ensure the positional accuracy of the positioned tool holder in the x-direction.

[0018] Furthermore, in one type of circulating tool magazine of this application, the tool holder is provided with a connecting structure, the connecting structure including locking blocks and locking grooves respectively arranged in pairs at both ends of the tool holder in the x direction;

[0019] When the transfer seat moves longitudinally to align with the storage layer, the tool holder on the transfer seat and the outer end of the tool holder on the storage layer are interlocked in the x-direction by locking blocks and locking slots. As a preferred embodiment of this application, adjacent pairs of tool holders are connected in the horizontal direction by locking blocks and locking slots at their proximal ends.

[0020] Furthermore, in a circulating tool magazine of this application, the transfer device includes a linear drive device disposed on a transfer seat on one side. A connector is provided on the movable component of the linear drive device. A sleeve structure adapted to the connector is provided on the side of the tool holder near the linear drive device. When the transfer seat moves to align with the storage layer, the connector and the sleeve structure longitudinally engage to achieve a transmission connection between the linear drive device and the tool holder. As a preferred embodiment of this application, based on the above device, its working method is as follows:

[0021] During the process of the linear drive device moving upward to the upper storage layer with the transfer seat, a tool holder is transferred on the transfer seat on one side of the linear drive device and the connector is engaged with the sleeve structure of the tool holder, while the transfer seat on the other side is empty.

[0022] When the transfer seat is aligned with the upper storage layer, the tool holder on the transfer seat and the upper storage layer are interlocked in the x direction through the connecting structure. At this time, the linear drive device is activated to push the tool holder on the transfer seat out and transfer it to the upper storage layer. At the same time, the tool holder at the far end of the storage layer is pushed and transferred to the transfer seat at the other end.

[0023] As the linear drive moves downward with the transfer seat, the connector disengages from the sleeve structure of the tool holder that has been transferred to the upper layer.

[0024] When the transfer seat aligns with the next storage layer, the connector engages with the tool holder at one end of the linear drive device on the lower storage layer. The tool holder on the other transfer seat is interlocked with the tool holder on the lower storage layer via a connecting structure. At this point, if the linear drive device is activated and the connector is pulled back, the tool holder connected to the connector will be pulled to the transfer seat on the corresponding linear drive device side, while the tool holder on the other transfer seat will be pulled to the lower storage layer.

[0025] This cycle allows for the cyclical transfer of the knife holder between the upper and lower storage layers.

[0026] Therefore, this application uses only one linear drive device to realize the transfer of the tool holder between the upper and lower storage layers and the transfer seats on both sides. It has the advantages of simple control and good reliability. In addition, the number of actuators of the transfer device is small, which has the advantage of saving manufacturing costs.

[0027] Furthermore, in one circulating tool magazine of this application, when the transfer seat moves to align with the upper storage layer, the tool holder on the transfer seat away from the linear drive device is placed in the tool changing station. The main frame is equipped with tool detection sensors that correspond one-to-one with the tool holders in the tool changing station. As a preferred embodiment of this application, the external tool handling robot transfers tools between itself and the tool holders in the tool changing station, and the tool detection sensors are used to detect whether the tool is on the tool holder.

[0028] Furthermore, in one type of circulating tool magazine of this application, a set of tool holders are arranged horizontally on the tool holder along a direction perpendicular to the x-axis.

[0029] Furthermore, in one embodiment of this application, a circulating tool magazine includes a lifting assembly comprising a lifting drive actuator and a movable frame slidably connected to the main frame. The lifting drive actuator is connected to the movable frame via a transmission connection, and a transfer seat is disposed on the movable frame.

[0030] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0031] This invention provides a circulating tool magazine. When the lifting assembly moves the transfer seat to align with the storage layer, the transfer device is activated, driving the tool holders on the storage layer to move horizontally. This transfers the tool holders at the front of the moving direction to a transfer seat on one side. The lifting assembly then moves the transfer seat to align with another storage layer, and the moving device is activated again, driving the tool holders to move in the opposite direction. This pushes the tool holders on the transfer seat into another storage layer and moves the tool holders in that layer, allowing the tool holders at the front of the moving direction to enter an empty transfer seat. Specifically, there is always one transfer seat containing a tool holder, and each storage layer is fully stocked with tool holders. When the transfer device is activated, the tool holders on one transfer seat are transferred to the storage layer, while the other transfer seat is used to store the removed tool holders. Therefore, the position of a group of tool holders on a single tool holder can be switched to achieve the transfer of multiple tools at once. This is suitable for multi-head machining equipment where multiple tools can be changed at once. Furthermore, the tool holders are stored in upper and lower storage layers and cyclically switched, offering the advantage of high space utilization. Attached Figure Description

Detailed Implementation

[0036] Combination Figs. 1 to 3 The illustrated circulating tool magazine includes:

[0037] Main frame 1, with a pair of storage layers spaced vertically on the main frame 1;

[0038] A set of tool holders 2, the tool holders 2 having a plurality of tool seats 20 for storing tools, the tool holders 2 being arranged along the x-direction on a pair of storage layers and the tool holders 2 being slidably connected to the storage layers along the x-direction;

[0039] The lifting assembly has a pair of transfer seats 32 spaced apart along the x-direction on its moving part. The pair of transfer seats 32 are located on the outer sides of both ends of the storage layer in the x-direction. The lifting assembly is used to drive the pair of transfer seats 32 to move up and down until the transfer seats 32 are reciprocally aligned with the pair of storage layers in the longitudinal direction.

[0040] A material transfer device is used to drive a set of tool holders 2 to slide on the storage layer to transfer the tool holders 2 at the front end of the sliding direction to the transfer seat 32.

[0041] Based on the above structure, the principle of the circulating tool magazine is as follows: When the lifting assembly moves the transfer seat 32 to align with the storage layer, the transfer device is activated, driving the tool holder 2 on the storage layer to move horizontally, so that the tool holder 2 at the front end of the moving direction is transferred to the transfer seat 32 on one side. The lifting assembly then moves the transfer seat 32 to align with another storage layer, and the moving device is activated again, driving the tool holder 2 to move in the opposite direction, thus pushing the tool holder 2 on the transfer seat 32 into another storage layer and driving the tool holder 2 in the storage layer to move, so that the tool holder 2 at the front end of the moving direction enters the empty transfer seat 32. Specifically, there is always a tool holder 2 on one transfer seat 32, and the tool holders 2 on each storage layer are fully occupied. When the transfer device is activated, the tool holder 2 on one transfer seat 32 is transferred to the storage layer, and the transfer seat 32 on the other side is used to store the moved-out tool holder 2.

[0042] Therefore, the positions of a group of tool holders 20 on a single tool holder 2 can be switched and moved to transfer multiple tools at once. This is suitable for multi-head machining equipment where multiple tools can be changed at once. Furthermore, the tool holder 2 stores and cycles through its upper and lower storage layers, offering the advantage of high space utilization.

[0043] In this embodiment, the storage layer is provided with a storage slide rail 11 extending along the x direction, and the knife holder 2 on the storage layer is slidably connected to the storage slide rail 11.

[0044] The transfer seat 32 is provided with a transfer slide rail 321 extending in the x direction, and the tool holder 2 that moves to the transfer seat 32 is slidably connected to the transfer slide rail 321.

[0045] In this embodiment, when the transfer seat 32 moves to the alignment of the storage layer, the transfer slide rail 321 and the storage slide rail 11 are engaged.

[0046] In this embodiment, a positioning device is also included, which is used to lock the tool holder 2 in the x direction;

[0047] The positioning device includes a movably configured positioning element 51 and a positioning driver 52 drivenly connected to the positioning element 51. The positioning driver 52 is used to drive the positioning element 51 to move so that the positioning element 51 locks the tool holder 2.

[0048] The positioning device is mounted on the transfer seat 32, and the positioning devices are arranged in pairs on both sides of the tool holder 2 on the transfer seat 32.

[0049] Based on the above device, the method of use is as follows: during the material transfer process, the positioning device unlocks the tool holder 2, and after the material transfer device completes the material transfer function, the positioning device locks the tool holder 2.

[0050] In this embodiment, a positioning structure is provided between the positioning member 51 and the tool holder 2. The positioning structure includes a V-shaped groove 24 and a protrusion that are mutually concave and convex.

[0051] When the protrusion and the V-groove 24 cooperate, they can correct the position of the tool holder 2 and ensure the positional accuracy of the positioned tool holder 2 in the x-direction. In this embodiment, the positioning driver 52 is a cylinder, the positioning member 51 is the telescopic rod of the cylinder, and the protrusion is located at the front end of the positioning member 51.

[0052] In this embodiment, the tool holder 2 is provided with a connecting structure, which includes locking blocks 21 and locking grooves 22 respectively arranged in pairs at both ends of the tool holder 2x direction; specifically, the locking grooves 22 and locking blocks 21 are mutually adapted to each other in a T shape.

[0053] When the transfer seat 32 moves longitudinally to align with the storage layer, the tool holder 2 on the transfer seat 32 and the outer end of the tool holder 2 on the storage layer are interlocked in the x direction by locking block 21 and locking groove 22.

[0054] A pair of adjacent tool holders 2 are connected in the horizontal direction through locking blocks 21 and locking grooves 22 at their near ends.

[0055] In this embodiment, the material transfer device includes a linear drive device 4 disposed on a transfer seat 32 on one side. The movable component of the linear drive device 4 is provided with a connector 41. The tool holder 2 is provided with a sleeve structure 23 adapted to the connector 41 on the side near the linear drive device 4. When the transfer seat 32 moves to align with the storage layer, the connector 41 and the sleeve structure 23 are longitudinally fitted together to realize the transmission connection between the linear drive device 4 and the tool holder 2.

[0056] Based on the above device, its working method is as follows:

[0057] During the process of the linear drive device 4 moving upward to the upper storage layer with the transfer seat 32, the tool holder 2 is transferred on the transfer seat 32 on one side of the linear drive device 4 and the connector 41 is engaged with the sleeve structure 23 of the tool holder 2, while the transfer seat 32 on the other side is empty.

[0058] When the transfer seat 32 is aligned with the upper storage layer, the tool holder 2 on the transfer seat 32 and the upper storage layer are interlocked in the x direction through the connecting structure. At this time, the linear drive device 4 is activated to push the tool holder 2 on the transfer seat 32 out and transfer it to the upper storage layer. At the same time, the tool holder 2 at the far end of the storage layer is pushed and transferred to the transfer seat 32 at the other end.

[0059] As the linear drive device 4 moves downward with the transfer seat 32, the connector 41 disengages from the sleeve structure 23 of the tool holder 2 that has been transferred to the upper layer.

[0060] When the transfer seat 32 is aligned with the next storage layer, the connector 41 engages with the sleeve structure 23 of the tool holder 2 near one end of the linear drive device 4 on the lower storage layer. The tool holder 2 on the other side of the transfer seat 32 is interlocked with the tool holder 2 near the lower storage layer through the connection structure. At this time, when the linear drive device 4 is activated and the connector 41 is pulled back, the tool holder 2 connected to the connector 41 will be pulled to the transfer seat 32 on the corresponding side of the linear drive device 4, while the tool holder 2 on the other side of the transfer seat 32 will be pulled to the lower storage layer.

[0061] This cycle allows the knife holder 2 to be transferred between the upper and lower storage layers.

[0062] Therefore, this application uses only one linear drive device 4 to realize the transfer of the tool holder 2 between the upper and lower storage layers and the transfer seats 32 on both sides. It has the advantages of simple control and good reliability. In addition, the number of actuators of the transfer device is small, which has the advantage of saving manufacturing costs.

[0063] Specifically, in this embodiment, the transfer seat 32 has the same structure as the locking groove 22, and the connector 41 has the same structure as the locking block 21.

[0064] In this embodiment, when the transfer seat 32 moves to align with the upper storage layer, the tool holder 2 on the transfer seat 32 away from the linear drive device 4 is placed in the tool changing station. The main frame 1 is provided with tool detection sensors 7 that correspond one-to-one with the tool holders 20 in the tool changing station.

[0065] The external tool handling robot transfers tools between itself and the tool holder 20 at the tool changing station. The tool detection sensor 7 is used to detect whether the tool 6 is on the tool holder 20. Specifically, the tool detection sensor is a photoelectric sensor.

[0066] In this embodiment, a set of tool holders 20 are arranged horizontally on the tool holder 2 along the direction perpendicular to x.

[0067] In this embodiment, the lifting assembly includes a lifting drive actuator 31 and a movable frame 33 that is slidably connected to the main frame 1. The lifting drive actuator 31 is connected to the movable frame 33 in a transmission manner, and the transfer seat 32 is disposed on the movable frame 33.
