Description

Technical Field

[0001] This utility model relates to the field of machine tools, and more particularly to a compact production line suitable for mass production. Background Technology

[0002] General-purpose machine tools refer to machine tools with a wide processing range that can be used to process various workpieces in different processes. Traditional general-purpose machine tools are usually operated independently. To ensure versatility, a single machine often sacrifices some efficiency and flexibility. For example, a general-purpose machining center is a type of machine tool with a high degree of versatility, but its processing efficiency is relatively low, especially its clamping efficiency, making it difficult to adapt well to large-scale production. Especially when machining parts with many processing steps, even machining centers with tool magazines cannot complete the processing operations with a single machine tool. Therefore, the coordinated operation of multiple machines is essential, but this undoubtedly further reduces processing efficiency.

[0003] Chinese invention patent application CN 118288111 A discloses a machine tool linkage production line and its control method. This machine tool linkage production line includes multiple machine tools, each equipped with an independent transfer device, and also includes a conveying device. The conveying device connects the multiple machine tools in series and is used for inputting workpieces to be processed and outputting processed workpieces. The transfer device can reciprocate between the conveying device and the corresponding machine tool and is equipped with a clamping mechanism for gripping workpieces. This machine tool linkage production line improves the efficiency of workpiece transfer between the machine tools, thereby increasing the overall processing efficiency to a certain extent.

[0004] However, the conveying devices in the aforementioned machine tool linkage production line can only convey workpieces sequentially in one direction, which results in insufficient flexibility and makes it difficult to adapt well to the processing needs of different types and quantities of products in different processes. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a compact production line suitable for mass production, which can flexibly set the processing mode according to different types of products, and can well balance versatility and flexibility.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A compact production line suitable for mass production, comprising at least:

[0007] The silo module includes a storage rack, and the storage rack is provided with a loading station.

[0008] The loading module includes a loading robot and a shifting component, wherein the loading robot includes a loading clamp.

[0009] The processing module includes a frame, on which processing components and a clamping station are provided. The clamping station is provided with a processing fixture. The loading fixture includes a chuck, and the number of chucks is at least two. Each chuck is arranged in parallel and works independently.

[0010] The number of processing modules is at least two, and each processing module operates independently. The shifting component is used to drive the loading robot to move between the storage rack and each processing module. The loading robot is used to drive the loading fixture to rotate between the loading station and the clamping station, or between the clamping stations of each processing module. By setting multiple grippers, multiple modular racks can be gripped at once, improving loading efficiency.

[0011] The various processing modules are linked and coordinated through the feeding module, and the multi-machine linkage can improve the overall processing capacity of the machine tool. At the same time, the cooperation between the feeding robot and the transfer component in the feeding module can realize the transfer between the hopper module and any two of the processing modules. For example, it can complete the transfer of materials from the discharge module to any processing module, the sequential transfer of materials along each processing module, the jump transfer of materials between non-adjacent processing modules, and the transfer of materials from any processing module to the hopper module, etc. The corresponding possible processing combinations are also more numerous, with the advantages of high efficiency and flexibility.

[0012] Preferably, the silo module further includes a feeding device mounted on a storage support. The feeding device includes a feeding conveying component and several material temporary storage components. The material temporary storage components are provided with material limiting units. The feeding conveying component is used to drive the material temporary storage components to move relative to the loading station.

[0013] During processing, the material is placed on the material storage component and limited by the material limiting unit. The feeding and conveying component is used to drive the movement of the material storage component, thereby realizing automated feeding.

[0014] Preferably, the silo module further includes a modular rack, which includes a base, a frame, and an adapter. The frame is columnar, with its lower end fixedly connected to the base and its upper end fixedly connected to the adapter. The base is provided with a clamping and positioning unit, and the sides of the frame are provided with several material clamps. The adapter matches the feeding clamps.

[0015] The material temporary storage component includes a mounting plate, which is connected to the feeding and conveying component. The material limiting unit is mounted on the mounting plate, and the modular material rack is detachably connected to the mounting plate through a clamping and positioning unit and a material limiting unit.

[0016] The base can be standardized to fit material storage components and processing fixtures, and the adapter connector can be standardized to fit feeding fixtures. The frame can directly clamp and position materials to be processed through material clamps. For different types and specifications of materials, standardized feeding and loading operations can be achieved by reasonably setting up material clamps, further improving the versatility of the machine tool.

[0017] Preferably, the storage rack is also provided with an operating station and a transition station. The operating station is located on one side of the transition station, and the feeding and conveying assembly is used to drive the material temporary storage assembly to move between the transition station and the loading station.

[0018] The material storage assembly further includes a locking unit, and the mounting plate is connected to the feeding and conveying assembly through the locking unit. The locking unit includes a locking seat, a locking element, and a locking block. The locking seat is connected to the feeding and conveying assembly, and the locking block is located at the bottom of the mounting plate. The upper surface of the locking seat is provided with a sliding groove, which extends to the side of the locking seat. The locking element includes a locking slider, which is slidably disposed in the sliding groove. A locking mechanism is provided between the locking slider and the locking seat. Two claws are rotatably connected to the side of the locking slider corresponding to the opening of the sliding groove. The two claws are arranged opposite each other, and an expansion elastic element is provided between the claws and the locking slider. A clamping groove is opened on the inner side of the two claws, and the clamping groove corresponds to the locking block. The claws have at least two position states: in the first position state, the two claws extend out of the sliding groove and expand to both sides under the elastic force of the expansion elastic element; in the second position state, the two claws at least partially enter the sliding groove and approach each other under the guidance and constraint of the sliding groove.

[0019] The operating station is used by operators to operate the modular rack, such as changing the modular rack and adjusting the material clamping status. The transition station is used for loading and unloading the modular rack.

[0020] During the loading operation of the modular material rack, the jaws are initially in the first position. The mounting plate is initially located at the operating station, and the corresponding locking unit is located at the transition station. The modular material rack is connected to the mounting plate through the clamping and positioning unit and the material limiting unit. Subsequently, a horizontal thrust is applied to the mounting plate, driving it to move towards the locking unit. When the locking block enters between the two jaws and contacts the locking slider, it pushes the locking slider to slide until the jaws enter the second position. The two jaws lock the locking block, and a horizontal connection is achieved between the mounting plate and the locking unit. It can then move between the transition station and the loading station under the drive of the feeding and conveying components.

[0021] When the modular rack is removed, a reverse horizontal force is applied to the mounting plate located at the transition station. The mounting plate and the modular rack move horizontally, the chuck returns to the first position, the mounting plate is unlocked from the locking unit, and the mounting plate and the modular rack can move smoothly to the operating station.

[0022] Preferably, the loading station is also provided with a lifting component, which includes a lifting drive unit and several lifting rods. The lifting drive unit is located below the loading station, and the lifting rods are set vertically upward. The lifting drive unit is used to drive the lifting to move vertically up and down.

The loading station is located between the two sets of blocking components. Limiting ears are provided on both sides of the mounting plate. When the material storage component is located at the loading station, the limiting ears extend into the bottom of the blocking components.

[0024] During the loading operation, the lifting drive unit drives the lifting rod upward, which abuts against the base of the modular rack and pushes the modular rack upward synchronously. Because the lifting limit unit and limit ear cooperate to prevent the mounting plate from lifting, the modular rack separates from the mounting plate. Once the modular rack is raised to the preset height, the loading module clamps the modular rack and performs subsequent loading operations.

[0025] Preferably, the displacement assembly includes a truss and a displacement drive assembly. The truss is horizontally arranged above the processing modules, and each processing module is arranged sequentially along the extension direction of the truss. The displacement drive assembly includes a displacement slider and a displacement power component.

[0026] Preferably, the loading robot includes a robotic arm that is slidably connected to a shifting slider, and the shifting slider is also provided with a loading drive component for driving the robotic arm to slide up and down; the gripper is located at the lower end of the robotic arm.

[0027] The truss-type transfer assembly, in conjunction with the robotic arm, enables three-dimensional transfer of modular material racks. Compared with existing transfer devices, the flexibility of loading is greatly improved, and it can be well adapted to different processing modes.

[0028] Preferably, the machining component is located on one side of the clamping station; the machining component includes a power head and a feed mechanism, the power head includes a cutting unit and a tool infeed drive unit, the cutting unit includes a cutting drive component and a tool head, the tool head is horizontally oriented toward the clamping station, the cutting drive component is used to drive the tool head to perform cutting operations, and the tool infeed drive unit is used to drive the cutting unit to infeed.

[0029] The feeding mechanism includes a transverse feed drive unit and a longitudinal feed drive unit.

The first mounting frame is vertically and movably connected to the frame, and the longitudinal feed drive component is used to drive the first mounting frame to move vertically. The transverse feed drive unit includes a second mounting frame and a transverse feed drive component. The second mounting frame is horizontally and movably connected to the first mounting frame, and the transverse feed drive component is used to drive the second mounting frame to move horizontally.

[0030] The machining fixture includes a fixture base and a rotary drive mechanism, wherein the rotary drive mechanism is used to drive the fixture base to rotate.

[0031] The power head enables the rotational drive and axial feed of the cutting tool, while the feed mechanism enables the transverse and longitudinal feeds of the power head. The feed mechanism and the power head work together to complete the machining operation. The orientation of the material can be adjusted by the rotational movement of the fixture, thereby enabling multi-angle machining operations.

[0032] Preferably, the frame is also provided with a tool magazine and a tool changing assembly, with the tool magazine located above the frame; the tool changing assembly includes a tool changing arm and a tool changing drive, the tool changing arm is provided with a tool clamping unit, and the tool changing drive is used to drive the tool changing arm to move between the tool head and the tool magazine.

[0059] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0060] like Figure 1 As shown, a compact production line suitable for mass production includes a hopper module 1, a feeding module 2, and a processing module 3.

[0061] like Figures 2-4 As shown, the silo module 1 includes a storage support 11, which is provided with a loading station 111, an operating station 112 and a transition station 113. The operating station 112 is located on one side of the transition station 113.

[0062] like Figures 2-6As shown, the silo module 1 further includes a feeding device 12 mounted on the storage support 11. The feeding device 12 includes a feeding conveyor assembly and several material temporary storage assemblies 16. The feeding conveyor assembly drives the material temporary storage assemblies 16 to move between the loading station 111 and the transition station 113. The feeding conveyor assembly includes a circular conveyor chain, with auxiliary support units on both sides of the conveyor chain. Each auxiliary support unit includes a support plate. The feeding conveyor assembly drives the material temporary storage assemblies 16 to move, thereby achieving automated feeding.

[0063] like Figures 10-13 As shown, the material storage assembly 16 includes a mounting plate 161 and a locking unit. The mounting plate 161 is provided with a material limiting unit 1611, and the mounting plate 161 is connected to the feeding and conveying assembly through the locking unit. During processing, the material is placed on the material storage assembly 16 and limited by the material limiting unit 1611.

[0064] like Figures 10-13 As shown, specifically, the locking unit includes a locking seat 1621, a locking element 162, and a locking block 1613. The locking seat 1621 is connected to the feeding and conveying assembly, and the locking block 1613 is disposed at the bottom of the mounting plate 161.

[0065] like Figures 10-13 As shown, the upper surface of the locking seat 1621 is provided with a sliding groove 1622, which extends to the side of the locking seat 1621. The locking member 162 includes a locking slider 1626, which is slidably disposed within the sliding groove 1622. A locking mechanism is provided between the locking slider 1626 and the locking seat 1621. Two claws 1623 are rotatably connected to the side of the locking slider 1626 corresponding to the opening of the sliding groove 1622. The two claws 1623 are arranged opposite each other, and an expansion elastic member 1624 is provided between the claws 1623 and the locking slider 1626. A clamping groove 1625 is formed on the inner side of the two claws 1623, which corresponds to the locking 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 expand to both sides under the elastic force of the expansion elastic member 1624; in the second position state, the two claws 1623 are at least partially inserted into the slide groove 1622 and approach each other under the guidance and constraint of the slide groove 1622.

[0066] Operating station 112 is used by operators to operate the modular material rack 14, such as replacing the modular material rack 14 and adjusting the material clamping status. Transition station 113 is used for loading and unloading the modular material rack 14.

[0067] During the loading operation of the modular material rack 14, the jaws 1623 are initially in the first position. The mounting plate 161 is initially located at the operating station 112, and the corresponding locking unit is located at the transition station 113. The modular material rack 14 is connected to the mounting plate 161 via the clamping and positioning unit 145 and the material limiting unit 1611. A horizontal thrust is then applied to the mounting plate 161, driving it towards the locking unit. When the locking block 1613 enters between the two jaws 1623 and contacts the locking slider 1626, it pushes the locking slider 1626 to slide until the jaws 1623 enter the second position. The two jaws 1623 lock the locking block 1613, achieving a horizontal connection between the mounting plate 161 and the locking unit. The mounting plate 161 can then move between the transition station 113 and the loading station 111 under the drive of the feeding and conveying assembly.

[0068] When the modular rack 14 is 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 rack 14 move horizontally, the chuck 1623 returns to the first position, the mounting plate 161 is unlocked from the locking unit, and the mounting plate 161 and the modular rack 14 can move smoothly to the operating station 112.

[0069] like Figures 7-9 As shown, the hopper module 1 further includes a modular material rack 14, which includes a base 144, a frame 142, and an adapter 141. The frame 142 is columnar, with its lower end fixedly connected to the base 144 and its upper end fixedly connected to the adapter 141. The base 144 is equipped with a clamping and positioning unit 145, and several material clamps 143 are distributed on the side of the frame 142. The adapter 141 matches the feeding clamps. The modular material rack 14 is detachably connected to the mounting plate 161 via the clamping and positioning unit 145 and the material limiting unit 1611.

[0070] like Figures 7-9 As shown, specifically, the frame 142 is prismatic in shape, and each side of the frame 142 is provided with a material clamp 143, which can be reasonably set to clamp the quantity of materials as needed. Each material clamp 143 includes a fixed clamping block and a movable clamping block, which are arranged vertically.

[0071] Specifically, such as Figure 9 and Figure 10As 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 provided on the mounting plate 161, and the material limiting unit 1611 is a limiting pin provided below the base 144.

[0072] The base 144 can achieve standardized adaptation with the material storage component 16 and the processing fixture 32, the adapter 141 can achieve standardized adaptation with the loading fixture, and the frame 142 can directly clamp and position the material to be processed through the material clamp 143. For different types and specifications of materials, standardized feeding and loading operations can be achieved by reasonably setting the material clamp 143, further improving the versatility of the processing machine tool.

[0073] like Figures 14-15 As shown, the loading station 111 is further equipped with a lifting assembly 13, which includes a lifting drive unit 131 and several lifting rods 132. The lifting drive unit 131 is located below the loading station 111, and the lifting rods 132 are vertically upward. The lifting drive unit 131 is used to drive the lifting rods to move vertically up and down. The mounting plate 161 has guide holes 1612 corresponding to the lifting rods 132, while the corresponding base 144 does not have through holes.

[0074] like Figures 14-15 As shown, the storage support 11 is also provided with a lifting and limiting unit, which includes two sets of blocking members 15. The loading station 111 is located between the two sets of blocking members 15. Limiting ears are provided on both sides of the mounting plate 161. When the material storage component 16 is located at the loading station 111, the limiting ears extend into the bottom of the blocking members 15.

[0075] During the loading operation, the lifting drive unit 131 drives the lifting rod 132 to move upward. The lifting rod 132 abuts against the base 144 of the modular rack 14 and pushes the modular rack 14 upward synchronously. Because the lifting limit unit and the limit ear cooperate to prevent the mounting plate 161 from lifting, the modular rack 14 separates from the mounting plate 161. After the modular rack 14 is lifted to the preset height, the loading module 2 clamps the modular rack 14 and performs subsequent loading operations.

[0076] like Figures 16-18As shown, the loading module 2 includes a loading robot and a shifting assembly. Specifically, the shifting assembly includes a truss 21 and a shifting drive assembly. The truss 21 is horizontally positioned above the processing modules 3, and each processing module 3 is arranged sequentially along the extension direction of the truss 21. The shifting drive assembly includes a shifting slider 23 and a shifting power component 26. The shifting slider 23 is slidably connected to the truss 21, and the shifting power component 26 is used to drive the shifting slider 23 to move.

[0077] like Figures 16-18 As shown, specifically, the loading robot includes a robotic arm 22 and a loading fixture. The robotic arm 22 is slidably connected to a shifting slider 23, and the shifting slider 23 is also provided with a loading drive component 25 for driving the robotic arm 22 to slide up and down. The loading fixture includes a chuck 24 disposed at the lower end of the robotic arm 22.

[0078] The truss 21 type shifting component, in conjunction with the robotic arm 22, can realize the three-dimensional transfer of the modular material rack 14. Compared with the transfer device in the prior art, the flexibility of loading is greatly improved, and it can be well adapted to different processing modes.

[0079] like Figures 16-18 As shown, specifically, the shifting power component 26 includes a first motor, a first transmission gear, and a first transmission rack. The first transmission rack is fixedly mounted on the truss 21 and arranged along the truss 21. The first motor and the first transmission gear are rotatably mounted on the shifting slider 23. The first transmission gear meshes with the first transmission rack, and the first motor drives the first transmission gear to rotate. The feeding drive component 25 includes a second motor, a second transmission gear, and a second transmission rack. The second transmission rack is fixedly mounted on the robotic arm 22 and arranged along the robotic arm 22. The second motor and the second transmission gear are rotatably mounted on the shifting slider 23. The second transmission gear meshes with the second transmission rack, and the second motor drives the second transmission gear to rotate.

[0080] Specifically, such as Figures 16-18 As shown, the loading fixture has at least two chucks 24, which are arranged in parallel and operate independently. By setting multiple chucks 24, multiple modular racks 14 can be gripped at once, improving loading efficiency. For example, when one of the processing modules 3 finishes processing, one chuck 24 grips the unprocessed modular rack 14, while the other chuck 24 grips the completed modular rack 14 on the processing module 3. The loading and unloading operations are completed by sequentially shifting positions.

[0081] like Figure 19 and Figure 20As shown, the processing module 3 includes a frame 31, on which processing components 33 and clamping stations are provided. The clamping stations are equipped with processing fixtures 32. There are at least two processing modules 3, each operating independently. The shifting component drives the loading robot to move between the storage support 11 and each processing module 3. The loading robot drives the loading fixture to rotate between the loading station 111 and the clamping station, or between the clamping stations of each processing module 3.

[0082] The various processing modules 3 are linked and coordinated through the feeding module 2. This multi-machine linkage improves the overall processing capacity of the machine tool. Simultaneously, the cooperation between the feeding robot and the shifting component in the feeding module 2 enables transfers between the hopper module 1 and any two of the processing modules 3. For example, it can transfer materials from the discharge module to any processing module 3, transfer materials sequentially along each processing module 3, perform jump transfers between non-adjacent processing modules 3, and transfer materials from any processing module 3 to the hopper module 1. This allows for a wider range of processing combinations, offering advantages of high efficiency and flexibility.

[0083] Specifically, such as Figure 19 and Figure 20 As shown, the machining assembly 33 is located on one side of the clamping station. The machining assembly 33 includes a power head 331 and a feed mechanism. The power head 331 includes a cutting unit and a tool feed drive unit. The cutting unit includes a cutting drive component and a tool head. The tool head is horizontally oriented towards the clamping station. The cutting drive component is used to drive the tool head to perform cutting operations, and the tool feed drive unit is used to drive the cutting unit to feed.

[0084] like Figure 24 As shown, the feeding mechanism includes a transverse feed drive unit 333 and a longitudinal feed drive unit 332. The longitudinal feed drive unit 332 includes a first mounting frame 3321 and a longitudinal feed drive component 3322. The first mounting frame 3321 is vertically movably connected to the frame 31, and the longitudinal feed drive component 3322 drives the first mounting frame 3321 to move vertically. The transverse feed drive unit 333 includes a second mounting frame 3332 and a transverse feed drive component 3331. The second mounting frame 3332 is horizontally movably connected to the first mounting frame 3321, and the transverse feed drive component 3331 drives the second mounting frame 3332 to move horizontally.

[0085] like Figure 21As shown, the machining fixture 32 includes a fixture base 322 and a rotary drive mechanism 321. The rotary drive mechanism 321 drives the fixture base 322 to rotate. The power head 331 enables the rotary drive and axial feed of the tool, while the feed mechanism enables the transverse and longitudinal feed of the power head 331. The feed mechanism and the power head 331 work together to complete the machining operation. The orientation of the material can be adjusted by the rotational movement of the fixture base 322, thereby enabling multi-angle machining operations.

[0086] Furthermore, such as Figures 22-25 As shown, the frame 31 is also equipped with a tool magazine 35 and a tool changing assembly 34, with the tool magazine 35 located above the frame 31. The tool changing assembly 34 includes a tool changing arm 342 and a tool changing drive unit 341. The tool changing arm 342 is equipped with a tool clamping unit 343, and the tool changing drive unit 341 is used to drive the tool changing arm 342 to move between the tool head and the tool magazine 35. Specifically, the tool changing arm 342 is rotatably connected to the frame 31 around a horizontal centerline, and the tool changing drive unit 341 is used to drive the tool changing arm 342 to rotate. Tool clamping units 343 are respectively provided at both ends of the tool changing arm 342. The tool magazine 35 can store tools, and tool changing can further expand the machining capabilities of the general-purpose machine tool.

[0088] At least the following steps are included:

[0089] S1. Set processing mode: Set the processing mode according to the type of product 4 to be processed and the processing procedure.
