[0002] General-purpose machine tools refer to machine tools with a wide range of processing and can be used to process a variety of workpieces in different processes. Traditional general-purpose machine tools are usually operated independently. In order to ensure versatility, a single device often loses some efficiency and flexibility. For example, a general-purpose machining center is a type of machine tool with a high degree of versatility, but the machining efficiency is low, especially the clamping efficiency is low, and it is difficult to adapt to large-scale production. Especially for the processing of parts with more processing procedures, even if a machining center with a tool magazine is used, it is difficult to complete the processing operation with only a single machine tool. Therefore, the coordination and linkage of multiple devices is imperative, but this will undoubtedly further reduce the processing efficiency.

[0003] The Chinese invention patent application with application publication number CN 118288111 A discloses a machine tool linkage production line and a control method thereof, the machine tool linkage production line includes multiple machine tools, each of which is provided with an independent transfer device, and also includes a transmission device, the transmission device is connected in series with the multiple machine tools and is used to input workpieces to be processed and output processed workpieces; the transfer device can reciprocate between the transmission device and the corresponding machine tool, and is provided with a clamping mechanism for grabbing the workpiece. The above-mentioned machine tool linkage production line improves the transfer efficiency of workpieces between each machine tool, and improves the overall processing efficiency to a certain extent.

A clamping groove 1625 is opened on the inner side of the two claws 1623, and the clamping groove 1625 corresponds to the clamping block 1613. The claws 1623 have at least two position states: in the first position state, the two claws 1623 extend out of the slide groove 1622, and the two claws 1623 expand to both sides under the elastic force of the expansion elastic member 1624; in the second position state, the two claws 1623 at least partially enter the slide groove 1622, and the two claws 1623 approach each other under the guidance and constraint of the slide groove 1622.

[0075] The operating station 112 is used for operators to operate the modular material rack 14, such as replacing the modular material rack 14, adjusting the material clamping state, etc. The transition station 113 is used for loading and unloading operations of the modular material rack 14.

[0076] When the modular rack 14 is loaded, the claw 1623 is initially in the first position. First, the mounting plate 161 is located at the operating station 112, and the corresponding locking unit is located at the transition station 113. The modular rack 14 is connected to the mounting plate 161 through the clamping and positioning unit 145 and the material limiting unit 1611.

The two claws 1623 lock the clamping block 1613, and the mounting plate 161 is horizontally connected to the locking unit, and can move between the transition station 113 and the loading station 111 under the drive of the feeding and conveying assembly.

[0077] When the modular material rack 14 is being removed, a reverse horizontal force is applied to the mounting plate 161 located at the transition station 113, the mounting plate 161 and the modular material rack 14 move horizontally, the claw 1623 returns to the first position, the mounting plate 161 and the locking unit are unlocked, and the mounting plate 161 and the modular material rack 14 can move smoothly to the operating station 112.

[0078] like Figure 7-Figure 9As shown, the silo module 1 also includes a modular material rack 14, which includes a base 144, a frame 142 and an adapter 141. The frame 142 is columnar, and the lower end of the frame 142 is fixedly connected to the base 144, and the upper end is fixedly connected to the adapter 141. A clamping and positioning unit 145 is provided on the base 144, and a plurality of material clamps 143 are distributed on the side of the frame 142. The adapter 141 matches the loading clamp. The modular material rack 14 is detachably connected to the mounting plate 161 through the clamping and positioning unit 145 and the material limiting unit 1611.

[0079] like Figure 7-Figure 9 As shown, specifically, the frame 142 is prism-shaped, and each side of the frame 142 is provided with a material clamp 143, and the number of clamped materials can be reasonably set according to demand. Each of the material clamps 143 includes a fixed clamp block and a movable clamp block, and the movable clamp block and the fixed clamp block are arranged in sequence up and down.

[0080] Specifically, Fig. 9 and Fig.10 As shown, one of the clamping and positioning unit 145 and the material limiting unit 1611 is a limiting pin, and the other is a limiting hole. Specifically, the clamping and positioning unit 145 includes a limiting hole arranged on the mounting plate 161, and the material limiting unit 1611 is a limiting pin arranged below the base 144.

[0083] like Figure 14-15As shown, the material storage bracket 11 is also provided with a lifting limit unit, and the lifting limit unit includes two groups of blocking members 15. The loading station 111 is located between the two groups of blocking members 15. Limiting ears are respectively provided on both sides of the mounting plate 161. When the material temporary storage assembly 16 is located at the loading station 111, the limiting ears extend under the blocking member 15.

[0084] During the loading operation, the lifting driving unit 131 drives the lifting rod 132 to move upward, and the lifting rod 132 abuts against the base 144 of the modular material rack 14, and pushes the modular material rack 14 to move upward synchronously. Since the lifting limit unit cooperates with the limit ear to prevent the mounting plate 161 from lifting, the modular material rack 14 is separated from the mounting plate 161. When the modular material rack 14 is lifted to a preset height, the loading module 2 clamps the modular material rack 14 and performs subsequent loading operations.

[0085] like Figure 16-Figure 18 As shown, the loading module 2 includes a loading manipulator and a shift assembly. Specifically, the shift assembly includes a truss 21 and a shift drive assembly. The truss 21 is horizontally arranged above the processing module 3, and each processing module 3 is arranged in sequence along the extension direction of the truss 21. The shift drive assembly includes a shift slider 23 and a shift power member 26. The shift slider 23 is slidably connected to the truss 21, and the shift power member 26 is used to drive the shift slider 23 to move.

[0089] Specifically, Figure 16-Figure 18 As shown, the number of the clamps 24 on the loading fixture is at least two, and each clamp 24 is arranged in parallel and works independently. By setting multiple clamps 24, multiple modular racks 14 can be clamped at one time, thereby improving the efficiency of loading. For example, when one of the processing modules 3 is processed, one clamp 24 clamps the unprocessed modular rack 14, and the other clamp 24 is used to clamp the processed modular rack 14 on the processing module 3, and the loading and unloading operations can be completed by sequentially shifting.

The loading manipulator is used to drive the loading fixture to shift between the loading station 111 and the clamping station, or between the clamping stations of each processing module 3.

[0091] Each processing module 3 is linked and coordinated through the loading module 2, and the multi-machine linkage can improve the overall processing capacity of the processing machine tool. At the same time, the loading manipulator and the shifting assembly in the loading module 2 can realize the transfer between any two of the silo module 1 and each processing module 3, for example: the material can be transferred from the discharge module to any processing module 3, the material can be transferred along each processing module 3 in sequence, the material can be transferred in a jumping manner between non-adjacent processing modules 3, and the material can be transferred from any processing module 3 to the silo module 1, etc. The corresponding processing form combinations that can be realized are also more, with the advantages of high efficiency and flexibility.
