Description

Technical Field

[0001] The present invention belongs to the technical field of steel structure component processing, and particularly relates to a production device for steel structure box columns. Background Art

[0002] In the production process of box columns, the first step is the erection and welding of webs and backing plates (diaphragms), which ensures the accuracy and stability of the web position and provides a solid foundation for subsequent steps. Next is the U-shaped erection stage, where a U-shaped structure is formed by combining two side plates and one bottom plate, and the corresponding welding operations are completed. However, in the current production process, there are some challenges in the U-shaped erection link.

[0003] Traditionally, the U-shaped erection of box columns relies on horizontal swing arms on both sides to limit and fix the side plates. Although this method can effectively maintain the position stability of the side plates, the width of the erection platform is significantly increased because additional space is required to accommodate the swing arms, which limits the effective use of the factory building space. To address this issue, the existing welding method usually adopts a design where the box column is moved while the spot welding device remains stationary. For example, a box column spot welding device described in Application No. CN202221839625.3 uses a conveying roller track assembly to transport the box column. However, this method of relying on moving the box column to reach different welding positions is difficult to ensure the accuracy of each welding position when performing U-shaped erection welding. In addition, moving large and heavy box columns is not only time-consuming and laborious but also increases energy consumption.

[0004] If we try to make the welding platform move freely in the length direction of the erection platform to improve welding accuracy, the welding platform needs to be designed longer than the erection platform, which will further occupy valuable factory building space and limit the flexibility of the production line layout. Although some innovative solutions have been proposed in existing technical documents, such as a welding production line for box beams described in Application No. CN202222505701.3, which uses clamping blocks in the clamping device to fix the side plates, effectively reducing the width of the erection platform and improving space utilization and operation flexibility. However, when such clamping methods are applied to the production of box columns with a relatively large height, due to the height limitation of the clamping blocks, they cannot effectively fix the higher side plates, thus affecting the stability and accuracy of the welding process.

[0005] Although a double-wire gas shielded welding laser vision automatic welding device for box columns described in Application No. CN201921766495.3 has successfully achieved mobile operation of the welding platform, this technical solution is only applicable to the welding of the corner welds of box columns and is not applicable to the erection welding process of box columns. Summary of the Invention

[0006] In view of this, the object of the present invention is to provide a production device for steel structure box columns, aiming to solve the problems existing in the prior art, such as the large width of the assembly platform and the inability to realize the mobile operation of the welding platform during the assembly of box columns, by optimizing the swing arm structures on both sides in the traditional box column production device.

[0007] To solve the above technical problems, the first technical solution of the present invention is a production device for steel structure box columns, including a clamping component, on which there is a swing arm for fixing the box column workpiece, and the clamping component has a retracted state and an operating state; an assembly platform, which is used for the assembly and welding operations of box columns, and there is a movable groove on the assembly platform for the swing arm to move; when assembling non-U-shaped columns, the clamping component is in the retracted state, and the swing arm is located below the assembly platform; when assembling U-shaped columns, the clamping component is in the operating state, and the swing arm extends out from the movable groove, and the swing arm limits the box column workpiece.

[0008] Preferably, the operating state is divided into a feeding state and a clamping state; when the clamping component is in the feeding state, there is an inclination angle between the swing arm and the assembly platform to facilitate the placement of the box column workpiece relying on the swing arm; when the clamping component is in the clamping state, the swing arm and the assembly platform are perpendicular to each other, and the box column workpiece is clamped and fixed by the swing arm.

[0009] Furthermore, the clamping component further includes a base, and there is a guiding structure on the base for assembling the swing arm; when the clamping component is in the retracted state, the guiding direction of the guiding structure is parallel to the length direction of the swing arm, and by changing the position of the swing arm on the guiding structure, the switching between the retracted state and the operating state of the clamping component is realized; when the clamping component is in the operating state, by changing the angle between the swing arm and the guiding structure, the switching between the feeding state and the clamping state of the clamping component in the operating state is realized.

[0010] Further, the guiding structure has a mounting block capable of sliding on the base, a linear moving member for driving the mounting block, and a limiting surface for restricting the movement of the swing arm. The mounting block and the swing arm are rotatably connected. Under the action of the limiting surface, the linear moving member controls the movement of the mounting block, thereby driving the position change of the swing arm on the guiding structure. The base also has a vertical surface, and the top end of the limiting surface intersects with the vertical surface. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the clamping member switches from the retracted state to the working state. At this time, the swing arm can rotate around the mounting block towards the vertical surface, realizing the switching between the discharging state and the clamping state of the clamping member in the working state. When the swing arm contacts the vertical surface, the clamping member switches from the discharging state to the clamping state.

[0011] Further, a driving motor is provided on the mounting block, and the output end of the driving motor is connected to the swing arm. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the driving motor drives the swing arm to rotate towards the vertical surface.

[0012] To solve the above technical problems, the second technical solution of the present invention is a steel structure box column production device, which provides another swing arm rotation solution, specifically as follows: The guiding structure has a control block capable of sliding on the base, and both the control block and the mounting block are controlled to move by the linear moving member. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the mounting block is fixed at the intersection, and the control block follows the movement of the mobile end of the linear moving member. A pushing block and a starting block are provided on the base. Both the pushing block and the starting block are at the intersection of the limiting surface and the vertical surface. The pushing block is located on the side close to the limiting surface, and the starting block is located on the side close to the vertical surface. A control circuit for connecting the pushing block and the starting block is provided on the base. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the control block pushes the starting block, and under the action of the control circuit, the pushing block is actuated, thereby realizing the pushing block pushing the swing arm to rotate towards the vertical surface.

[0013] Furthermore, a clamping block and an activation block are provided on the base. The clamping block and the activation block are located between the pushing block and the starting block. The clamping block is located on the side close to the limiting surface, and the activation block is located on the side close to the vertical surface. A transmission circuit for connecting the clamping block and the activation block is formed on the base. After the mounting block reaches the intersection of the limiting surface and the vertical surface, the control block pushes the starting block to activate the activation block. Under the action of the transmission circuit, the clamping block extends out, thereby restricting the movement of the mounting block.

[0014] Furthermore, the swing arm includes a sliding member and a swinging member. The sliding member and the swinging member are slidably connected. The sliding member is rotatably connected to the mounting block. One end of the swinging member is rotatably connected to the intersection of the limiting surface and the vertical surface of the base. After the mounting block reaches the intersection of the limiting surface and the vertical surface, the control block pushes the starting block. Under the action of the control circuit, the pushing block is actuated to push the swinging member to rotate, so that the sliding member rotates towards the direction of the vertical surface.

[0015] To solve the above technical problems, the third technical solution of the present invention is a usage method of the steel structure box column production device described in the first technical solution. The usage method includes the following steps:

[0016] 1) Clamping component state switching: From the retracted state to the working state, the installation block is driven to slide along the guiding structure by controlling the linear moving component until the installation block reaches the intersection of the limiting surface and the vertical surface, completing the conversion from the retracted state to the working state. From the feeding state to the clamping state, the swing arm is driven to rotate by the driving motor. When the swing arm is perpendicular to the assembly platform, the conversion from the feeding state to the clamping state is completed.

[0017] 2) Box column assembly process: When performing non-U-shaped assembly, the clamping component remains in the retracted state. If the clamping component is not required to fix the box column workpiece, the clamping component remains in the retracted state. At this time, the swing arm is located below the assembly platform, without interfering with other operations of box column production. When performing U-shaped assembly, the clamping component remains in the working state. When the box column workpiece needs to be placed, the driving motor drives the swing arm to rotate to a position inclined to the assembly platform, facilitating the placement of the workpiece. After the box column workpiece is placed in place, the driving motor is continued to adjust the swing arm to make the swing arm perpendicular to the assembly platform, clamping and fixing the box column workpiece, and preparing for assembly or welding operations. After completing the assembly or welding operations, the above steps can be repeated to adjust the clamping component back to the retracted state to prepare for the next operation.

[0018] To solve the above technical problems, the fourth technical solution of the present invention is a method for using the steel structure box column production device described in the second technical solution, and the method includes the following steps:

[0019] 1) Clamping component state switching: From the retracted state to the working state, it is achieved by controlling the linear moving component to drive the mounting block to slide along the guiding structure until the mounting block reaches the intersection of the limiting surface and the vertical surface, completing the conversion from the retracted state to the working state; From the feeding state to the clamping state, the control block pushes the excitation block, and under the action of the transmission circuit, the clamping block extends to restrict the movement of the mounting block and prevent unnecessary displacement during operation; At the same time, the control block will push the starting block, and under the action of the control circuit, the pushing block will act. The action of the pushing block will push the swinging member, causing the swinging member to rotate towards the vertical surface direction with the mounting block as the center point. When the swing arm is perpendicular to the assembly platform, the conversion from the feeding state to the clamping state is completed;

[0020] 2) Box column assembly process: During non-U-shaped assembly, the clamping component remains in the retracted state; When it is not necessary to use the clamping component to fix the box column workpiece, the clamping component remains in the retracted state. At this time, the swing arm is located below the assembly platform and does not interfere with other operations of box column production; During U-shaped assembly, the clamping component remains in the working state; When it is necessary to place the box column workpiece, the linear moving component moves the control block, thereby pushing the starting block, and through the control circuit, the pushing block acts, causing the swing arm to rotate a certain angle towards the vertical surface direction to form an inclination angle for facilitating the placement of the box column workpiece; After the box column workpiece is placed in place, continue to move the control block by moving the component to push the starting block until the swing arm is perpendicular to the assembly platform to clamp and fix the box column workpiece, preparing for assembly or welding operations; After completing the assembly or welding operations, the above steps can be repeated to adjust the clamping component back to the retracted state to prepare for the next operation.

[0021] The technical effects of the present invention are mainly reflected in the following aspects:

[0022] By designing a multi-state switching mechanism for the clamping component (including the retracted state, working state, feeding state, and clamping state), the production process is significantly optimized: The retracted state effectively reduces the width of the assembly platform and improves the utilization rate of the factory building space; The switching between the feeding and clamping states in the working state not only facilitates workpiece placement but also ensures high stability and accuracy during the welding process;

[0023] By designing the clamping component to be in a retracted state during non-U-shaped assembly and placing the swing arm below the assembly platform, the present invention significantly reduces the additional space required for the assembly platform. This design not only effectively reduces the overall floor area of the production device but also improves the space utilization rate of the factory building, making the production line layout more flexible and efficient. Allowing the welding platform to move freely in the length direction of the assembly platform makes it possible to improve the accuracy of the welding position. Compared with traditional methods that rely on moving box-shaped columns, this solution ensures high stability and accuracy during the welding process, while reducing energy consumption and manual intervention, and enhancing the overall operational flexibility and efficiency.

[0024] Introducing a drive motor to achieve angle adjustment of the swing arm greatly simplifies the operation process and reduces the need for manual adjustment. In addition, the application of automated components ensures the consistency and accuracy of each angle adjustment, enhancing the stability and reliability of the system. This improvement not only increases work efficiency but also reduces the operation difficulty and error rate. At the same time, by using a mechanical linkage mechanism composed of control blocks, starting blocks, clamping blocks, etc. to replace the drive motor, precise angle adjustment of the swing arm and position locking of the mounting block are achieved. This design not only improves the reliability and safety of the system but also enables easy switching of the clamping component between various states through the drive of linear moving components.

Detailed implementation mode

[0033] The following further details the specific implementation mode of the present invention in conjunction with the attached drawings, so that the technical solution of the present invention is easier to understand and master. In the embodiment, it should be understood that the orientation or positional relationship indicated by terms such as "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle part", etc. is based on the orientation or positional relationship shown in the attached drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention. In addition, in this specific implementation mode, if the connection or fixing method between components is not specifically stated, the connection or fixing method can be bolt fixing or pin fixing commonly used in the prior art, or pin shaft connection, etc. Therefore, it will not be elaborated in this embodiment.

[0034] A steel structure box column production device provided by the present invention is mainly applied to the U-shaped assembly operation of box columns, but this should not be used as a limitation, and it can also be used in other similar or identical welding and production processes.

[0035] Embodiment 1

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7, this embodiment discloses a production device for a steel structure box column, including a clamping component 1. The clamping component 1 is provided with a swing arm 11 for fixing the box column workpiece, and the clamping component 1 has a retracted state and an operating state; an assembly platform 3, which is used for the assembly and welding operations of the box column. The assembly platform 3 is provided with a movable groove 31 for the swing arm 11 to move. The movable groove 31 ensures that the swing arm 11 can move freely without being hindered. When assembling non-U-shaped columns, the clamping component 1 is in the retracted state, and the swing arm 11 is located below the assembly platform 3, not occupying extra space; when assembling U-shaped columns, the clamping component 1 is in the operating state, and the swing arm 11 extends out from the movable groove 31, and the workpiece of the box column is limited by the swing arm 11; greatly reducing the width required for the assembly platform 3 and improving the utilization rate of the factory building space. Compared with the previous method of relying on moving the box column to achieve different welding positions, this solution allows the welding platform to move flexibly in the length direction of the assembly platform 3, while maintaining good controllability of large and heavy box columns, thus achieving higher welding accuracy and operation flexibility.

[0037] See Figure 3 and Figure 4 , the operating state is divided into a feeding state and a clamping state; when the clamping component 1 is in the feeding state, there is an inclination angle between the swing arm 11 and the assembly platform 3, so as to facilitate the placement of the box column workpiece by relying on the swing arm 11, reducing the time and effort required for manual adjustment and improving work efficiency. When the clamping department is in the clamping state, the swing arm 11 and the assembly platform 3 are in a vertical relationship, and the box column workpiece is clamped and fixed by the swing arm 11, ensuring that the box column can maintain a high degree of stability during the welding process and guaranteeing the welding quality.

[0038] See Figure 5 , the clamping component 1 further includes a base 12, and the base 12 is provided with a guiding structure 13 for assembling the swing arm 11; when the clamping component 1 is in the retracted state, the guiding direction of the guiding structure 13 is parallel to the length direction of the swing arm 11, and by changing the position of the swing arm 11 on the guiding structure 13, the switching between the retracted state and the operating state of the clamping component 1 is realized; when the clamping component 1 is in the operating state, by changing the included angle between the swing arm 11 and the guiding structure 13, the switching between the feeding state and the clamping state of the clamping component 1 in the operating state is realized.

[0039] See Figure 5, the guiding structure 13 has a mounting block 14 capable of sliding on the base 12, a linear moving member 15 for driving the mounting block 14, and a limiting surface 16 for restricting the movement of the swing arm 11. The mounting block 14 and the swing arm 11 are rotatably connected, allowing the swing arm 11 to rotate around the mounting block 14 as the center point; the design of the limiting surface 16 ensures the stability and accuracy of the swing arm 11 in any state. Especially during the process of switching from the feeding state to the clamping state, it ensures the safe fixation of the box-shaped column workpiece and improves the welding quality. Under the action of the limiting surface 16, the mounting block 14 is controlled by the linear moving member 15 to move, thereby driving the position change of the swing arm 11 on the guiding structure 13; the base 12 also has a vertical surface 17, and the top end of the limiting surface 16 intersects with the vertical surface 17; when the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, the clamping member 1 switches from the retracted state to the working state; at this time, the swing arm 11 can rotate around the mounting block 14 towards the direction of the vertical surface 17, realizing the switching of the clamping member 1 between the feeding state and the clamping state in the working state; when the swing arm 11 contacts the vertical surface 17, the clamping member 1 switches from the feeding state to the clamping state. By introducing the adjustable guiding structure 13 and the angle adjustment mechanism of the swing arm 11, not only the flexible switching of the clamping member 1 between the retracted state and the working state is realized, but also different production requirements and box-shaped column sizes can be adapted.

[0040] A driving motor is provided on the mounting block 14, and the output end of the driving motor is connected to the swing arm 11; when the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, the driving motor drives the swing arm 11 to rotate towards the direction of the vertical surface 17. With the help of the driving motor, the swing arm 11 can accurately complete the conversion from the feeding state to the clamping state; not only improves the automation degree of the operation, reduces the need for manual intervention, but also ensures the consistency and accuracy of each angle adjustment, enhancing the stability and reliability of the entire system.

[0041] Embodiment 2

[0042] This embodiment discloses a production device for steel structure box-shaped columns. Compared with the production device in Embodiment 1, this embodiment provides a new control scheme for switching the clamping member 1 between the retracted state and the working state, which is as follows:

[0043] See Figure 5 and Figure 6, the guiding structure 13 has a control block 18 that can slide on the base 12, and both the control block 18 and the mounting block 14 are controlled to move by the linear moving member 15; the control block 18, the mounting block 14 and the moving end of the linear moving member 15 are connected by magnetic attraction or snap connection, so as to facilitate the separation of the control block 18 and the mounting block 14 at the junction of the limiting surface 16 and the vertical surface 17. When the mounting block 14 reaches the junction of the limiting surface 16 and the vertical surface 17, the mounting block 14 fixes the junction, and the control block 18 moves following the moving end of the linear moving member 15; a pushing block 19 and a starting block 20 are arranged on the base 12, both the pushing block 19 and the starting block 20 are at the junction of the limiting surface 16 and the vertical surface 17, the pushing block 19 is located on the side close to the limiting surface 16, and the starting block 20 is located on the side close to the vertical surface 17; a control circuit 21 for connecting the pushing block 19 and the starting block 20 is opened on the base 12; when the mounting block 14 reaches the junction of the limiting surface 16 and the vertical surface 17, the starting block 20 is pushed by the control block 18, and under the action of the control circuit 21, the pushing block 19 acts, so as to realize that the pushing block 19 pushes the swing arm 11 to rotate towards the direction of the vertical surface 17.

[0044] See Figure 6 , a clamping block 22 and an excitation block 23 are arranged on the base 12, the clamping block 22 and the excitation block 23 are located between the pushing block 19 and the starting block 20, the clamping block 22 is located on the side close to the limiting surface 16, and the excitation block 23 is located on the side close to the vertical surface 17; a transmission circuit 24 for connecting the clamping block 22 and the excitation block 23 is opened on the base 12; when the mounting block 14 reaches the junction of the limiting surface 16 and the vertical surface 17, the excitation block 23 is pushed by the control block 18 through the starting block 20, and under the action of the transmission circuit 24, the clamping block 22 extends out, so as to realize that the clamping block 22 restricts the movement of the mounting block 14.

[0045] See Figure 6, the swing arm 11 includes a sliding member and a swinging member, the sliding member and the swinging member are slidably connected, the sliding member is rotatably connected to the mounting block 14, and one end of the swinging member is rotatably connected to the intersection of the limiting surface 16 and the vertical surface 17 of the base 12; when the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, the control block 18 pushes the starting block 20, and under the action of the control circuit 21, the pushing block 19 acts, so that the pushing block 19 pushes the swinging member to rotate, thereby causing the sliding member to rotate towards the direction of the vertical surface 17. The rotation length of the swing arm 11 of the above equipment is optimized, and the effect of the pushing block 19 pushing the swing arm 11 to rotate is as follows: when the angle of the swing arm 11 needs to be adjusted (for example, switched from the feeding state to the clamping state), the pushing block 19 acts on the swinging member. Due to the sliding connection between the sliding member and the swinging member, the actual force received by the swing arm 11 can be adjusted according to the acting point and direction of the force. This method actually applies the lever principle, that is, by changing the length of the force arm to adjust the magnitude of the force required to be applied, so that a smaller force can produce a larger rotation effect, effectively reducing energy consumption and improving operation efficiency. By introducing two sets of mechanisms of the pushing block 19 and the starting block 20, and the clamping block 22 and the excitation block 23, not only the precise angle adjustment of the swing arm 11 is realized, but also the stability of the mounting block 14 at the key position is ensured, and the reliability and safety of the whole system are improved. And by using the linear moving member 15 to cooperate with the control circuit 21 and the transmission circuit 24, a series of automated operation steps are realized, including the angle adjustment of the swing arm 11 and the position locking of the mounting block 14, reducing the need for manual intervention and improving work efficiency.

[0046] Embodiment III

[0047] This embodiment discloses a use method of the steel structure box column production device described in Embodiment I. The use method includes the following steps:

[0048] 1) Clamping component 1 state switching: The switching from the retracted state to the working state is achieved by controlling the linear moving member 15 to drive the mounting block 14 to slide along the guiding structure 13 until the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, completing the conversion from the retracted state to the working state; the switching from the feeding state to the clamping state is achieved by driving the motor to drive the swing arm 11 to rotate. When the swing arm 11 is perpendicular to the assembly platform 3, the conversion from the feeding state to the clamping state is completed;

[0049] 2) Box column assembly process: When performing non-U-shaped assembly, the clamping component 1 remains in the retracted state; if it is not necessary to use the clamping component 1 to fix the box column workpiece, the clamping component 1 is kept in the retracted state. At this time, the swing arm 11 is located below the assembly platform 3, without interfering with other operations in the production of box columns; when performing U-shaped assembly, the clamping component 1 remains in the working state; when it is necessary to place the box column workpiece, the drive motor drives the swing arm 11 to rotate to a position inclined to the assembly platform 3, facilitating the placement of the workpiece; after the box column workpiece is placed in place, the swing arm 11 is continuously adjusted by the drive motor to make the swing arm 11 perpendicular to the assembly platform 3, clamping and fixing the box column workpiece, and preparing for assembly or welding operations; after completing the assembly or welding operations, the above steps can be repeated to readjust the clamping component 1 to the retracted state to prepare for the next operation.

[0050] Embodiment 4 provides a relatively direct method to switch the state of the clamping component 1, mainly relying on the coordinated work of the linear moving component 15 and the drive motor, simplifying the operation process and being suitable for a production environment that requires high efficiency and quick response.

[0051] Embodiment Four

[0052] This embodiment discloses a usage method of the steel structure box column production device described in Embodiment 2, and the usage method includes the following steps:

[0053] 1) State switching of the clamping component 1: From the retracted state to the working state, it is achieved by controlling the linear moving component 15 to drive the mounting block 14 to slide along the guiding structure 13 until the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, completing the conversion from the retracted state to the working state; from the feeding state to the clamping state, the control block 18 pushes the excitation block 23, and under the action of the transmission circuit 24, the clamping block 22 extends to restrict the movement of the mounting block 14 to prevent unnecessary displacement during the operation; at the same time, the control block 18 will push the starting block 20, and under the action of the control circuit 21, the pushing block 19 will act. The action of the pushing block 19 will push the swinging part, causing the swinging part to rotate around the mounting block 14 towards the direction of the vertical surface 17. When the swing arm 11 is perpendicular to the assembly platform 3, the conversion from the feeding state to the clamping state is completed.

[0054] 2) Box column assembly process: When performing non-U type assembly, the clamping component 1 remains in the retracted state; when it is not necessary to use the clamping component 1 to fix the box column workpiece, the clamping component 1 is kept in the retracted state. At this time, the swing arm 11 is located below the assembly platform 3 and does not interfere with other operations in the production of box columns; when performing U type assembly, the clamping component 1 remains in the working state; when it is necessary to place the box column workpiece, the linear moving component 15 moves the control block 18, thereby pushing the starting block 20, and through the control circuit 21, the pushing block 19 is actuated, so that the swing arm 11 rotates a certain angle in the direction of the vertical plane 17 to form an inclination angle, facilitating the placement of the box column workpiece; after the box column workpiece is placed in place, continue to push the starting block 20 in the way of moving the control block 18 through the moving component until the swing arm 11 is perpendicular to the assembly platform 3, and clamp and fix the box column workpiece to prepare for assembly or welding operations; after completing the assembly or welding operations, the above steps can be repeated to adjust the clamping component 1 back to the retracted state to prepare for the next operation.

[0055] This embodiment introduces a more complex mechanical linkage mechanism (such as the control block 18, the starting block 20, the clamping block 22, etc.). Although it increases the complexity of the system, it provides higher stability and accuracy, and the clamping component 1 can be directly switched between various states through the drive of the linear moving component 15.

[0056] In addition, as common knowledge in this industry, in addition to the assembly platform 3 mentioned above, the production device is also equipped with a welding platform. In addition, the assembly platform 3, the welding platform, the linear moving component 15 and the drive motor mentioned above; in addition, both the transmission circuit 24 and the control circuit 21 can be hydraulic circuits filled with liquid, and the starting block 20 and the excitation block 23 are both provided with springs for controlling their own reset. The above is common knowledge; therefore, the principle and structure are not described in detail herein.

[0057] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
