Description

Technical Field

[0001] This utility model relates to the technical field of welding positioning, specifically to a welding assembly positioning frame for the inner reinforcing plate of a longitudinal beam. Background Technology

[0002] The longitudinal beam of an automobile is a beam that runs along the axial direction of a bridge and is supported on the crossbeams in the superstructure of an automobile. It is a fundamental component that bears the body and effective load of the vehicle, serving as the backbone of the automobile. The internal reinforcing plate of the longitudinal beam is a localized strengthening component welded or riveted inside the longitudinal beam. It is typically composed of two Z-shaped reinforcing plates welded together. From bottom to top, the Z-shaped reinforcing plate includes a base plate, side plates, and an edge plate. Before welding the two Z-shaped reinforcing plates, a positioning frame is used to position and fix them, facilitating subsequent welding of the overlapping portion of the base plates.

[0003] Existing positioning frames typically include a bracket, positioning pins mounted on the bracket, and clamping components. The bracket supports the base plate of the Z-shaped reinforcing plate, the positioning pins engage with the positioning holes on the Z-shaped reinforcing plate, and the clamping components clamp and secure the edges and sides of the two Z-shaped reinforcing plates. The specific operating procedure is as follows: First, align the positioning holes on the two Z-shaped reinforcing plates with the positioning pins. Then, place the base plate of the Z-shaped reinforcing plate on the bracket, forming an overlapping area. Finally, use the clamping components to clamp the edges and sides of the two Z-shaped reinforcing plates. In this way, the two Z-shaped reinforcing plates are fixed to the positioning frame, allowing welding of the overlapping area of ​​the base plates, thus combining the two Z-shaped reinforcing plates into a single inner reinforcing plate.

[0004] However, the positions of the positioning pins and clamping parts in the existing positioning frame are relatively fixed, which cannot meet the positioning and clamping requirements of the reinforcing plates inside the longitudinal beams of different widths. Utility Model Content

[0005] The present invention aims to provide a welded assembly positioning frame for the inner reinforcing plate of the longitudinal beam, so as to solve the technical problem that the positioning pins and clamping parts in the existing positioning frame are relatively fixed in position and cannot adapt to the positioning and clamping requirements of the inner reinforcing plate of the longitudinal beam with different widths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The longitudinal beam inner reinforcing plate welding assembly positioning frame includes a bracket, a support block, a positioning clamping assembly, and a linkage part. The support block is fixed in the middle of the bracket. There are two positioning clamping assemblies, which are respectively located on both sides of the support block. Both positioning clamping assemblies can be moved left and right to connect to the bracket. The linkage part is linked to the two positioning clamping assemblies so that the two positioning clamping assemblies move closer or further away from each other synchronously.

[0008] Furthermore, the positioning and clamping assembly includes multiple positioning and clamping parts, which are arranged at intervals along the axial direction of the support block.

[0009] Furthermore, the positioning and clamping part includes a mounting plate, a positioning pin, and a clamping member. The positioning pin is fixed on the mounting plate and can be fitted into the positioning hole of the Z-shaped reinforcing plate. The clamping member is used to clamp the edge and side plate of the Z-shaped reinforcing plate.

[0010] Furthermore, the clamping member includes a support plate, a connecting plate, and a clamping arm. The support plate is fixedly mounted on the mounting plate, the connecting plate is fixedly connected to the support plate, and the clamping arm is rotatably connected to the connecting plate. The lower side of the end of the clamping arm near the support block forms a space between the support plate and the Z-shaped reinforcing plate for limiting the edge and side plate.

[0011] Furthermore, it also includes a linear drive, which includes a first housing and has an upwardly extending first output shaft. The first housing of the linear drive is rotatably connected to the lower side of the connecting plate. The free end of the first output shaft is rotatably connected to the end of the clamping arm away from the support plate. The middle part of the clamping arm is rotatably connected to the upper side of the connecting plate.

[0012] Furthermore, the linear drive component is one of a cylinder, a hydraulic cylinder, and an electric actuator.

[0013] Furthermore, the linkage includes a first electric push rod and a second electric push rod. The support block has a second housing for accommodating the first electric push rod and the second electric push rod. The first electric push rod has a second output shaft extending away from the second electric push rod, and the free end of the second output shaft is fixedly connected to one of the positioning and clamping components. The second electric push rod has a third output shaft extending away from the first electric push rod, and the free end of the third output shaft is fixedly connected to another positioning and clamping component.

[0014] The beneficial effects of this utility model are as follows:

[0015] Before welding the two Z-shaped reinforcing plates, the linkage mechanism drives the two positioning clamping assemblies to move away from each other synchronously. Then, the worker lifts the two Z-shaped reinforcing plates and places their base plates onto the support block in sequence. Simultaneously, the positioning clamping assemblies position the Z-shaped reinforcing plates and then clamp them along their edges and side plates. In this structure, the Z-shaped reinforcing plates are fixed to the positioning clamping assemblies. After fixing the Z-shaped reinforcing plates to the positioning clamping assemblies, the linkage mechanism drives the two positioning clamping assemblies to move closer to each other synchronously, increasing the overlapping area of ​​the base plates of the two Z-shaped reinforcing plates. This creates a welding area where the two Z-shaped reinforcing plates can be welded together to form a single inner reinforcing plate.

[0016] In this utility model, the two positioning and clamping components in the welded combination positioning frame for the inner reinforcing plate of the longitudinal beam can move closer or further apart synchronously, which can adapt to the positioning and clamping requirements of the inner reinforcing plate of the longitudinal beam with different widths.

[0017] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible.

[0026] Please see Figure 1-2 This utility model provides a technical solution: a welding assembly positioning frame for the inner reinforcing plate of a longitudinal beam, including a bracket 1, a support block 2, a positioning clamping assembly, and a linkage part. The support block 2 is fixed in the middle of the bracket 1. There are two positioning clamping assemblies, which are respectively located on both sides of the support block 2. Both positioning clamping assemblies can be moved left and right to connect to the bracket 1. The linkage part is linked to the two positioning clamping assemblies so that the two positioning clamping assemblies move closer or further away from each other synchronously. In this embodiment, the support block 2 is elongated and is used to support the bottom plate of the Z-shaped reinforcing plate. The positioning clamping assembly is used to position the Z-shaped reinforcing plate and clamp the edges and side plates of the Z-shaped reinforcing plate.

[0027] Before welding the two Z-shaped reinforcing plates, the linkage unit drives the two positioning clamping components to move away from each other synchronously. Then, the worker lifts the two Z-shaped reinforcing plates and places the bottom plates of the two Z-shaped reinforcing plates on the support block 2 in sequence. At the same time, the positioning clamping components position the Z-shaped reinforcing plates and then clamp the edges and side plates of the Z-shaped reinforcing plates. In this way, the Z-shaped reinforcing plates can be fixed on the positioning clamping components.

[0028] After the Z-shaped reinforcing plate is fixed on the positioning and clamping assembly, the linkage drives the two positioning and clamping assemblies to move closer to each other synchronously, so that the overlapping area of ​​the bottom plates of the two Z-shaped reinforcing plates increases, forming a welding area where the two Z-shaped reinforcing plates can be welded together. In this way, the two Z-shaped reinforcing plates can be welded together to form an integral inner reinforcing plate.

[0029] In this utility model, the two positioning and clamping components in the welded combination positioning frame for the inner reinforcing plate of the longitudinal beam can move closer or further apart synchronously, which can adapt to the positioning and clamping requirements of the inner reinforcing plate of the longitudinal beam with different widths.

[0030] In this embodiment, the positioning and clamping assembly includes two positioning and clamping parts, which are arranged at intervals along the axial direction of the support block 2. With this structure, multiple points of the Z-shaped reinforcing plate can be positioned simultaneously, and multiple points along the edge and side plate of the Z-shaped reinforcing plate can be clamped. The positioning and clamping assembly provides better positioning and clamping effect for the Z-shaped reinforcing plate, and the Z-shaped reinforcing plate can be better fixed on the positioning and clamping assembly.

[0031] In this embodiment, the positioning and clamping part includes a mounting plate 31, a positioning pin, and a clamping member 32. The positioning pin is fixed on the mounting plate 31 and can be fitted into the positioning hole of the Z-shaped reinforcing plate. The clamping member 32 is used to clamp the edge and side plate of the Z-shaped reinforcing plate.

[0032] When placing the Z-shaped reinforcing plate, first align the positioning hole of the Z-shaped reinforcing plate with the positioning pin, and then place the Z-shaped reinforcing plate down. The positioning pin fits into the positioning hole of the Z-shaped reinforcing plate. With this structure, the positioning clamping assembly can be used to position the Z-shaped reinforcing plate.

[0033] In this embodiment, the clamping member 32 includes a support plate 321, a connecting plate 322, and a clamping arm 323. The support plate 321 is fixedly mounted on the mounting plate 31, the connecting plate 322 is fixedly connected to the support plate 321, and the clamping arm 323 is rotatably connected to the connecting plate 322. The lower side of the end of the clamping arm 323 near the support block 2 forms a space between the support plate 321 and the Z-shaped reinforcing plate for limiting the edge and side plate. In this embodiment, the support plate 321 is a cuboid, and the distance between the upper end face of the support plate 321 and the upper end face of the support block 2 is equal to the distance between the lower side of the edge of the Z-shaped reinforcing plate and the upper side of the bottom plate of the Z-shaped reinforcing plate.

[0034] Before placing the Z-shaped reinforcing plate, rotate the clamping arm 323 away from the support plate 321 to avoid the clamping arm 323 interfering with the placement and positioning of the Z-shaped reinforcing plate.

[0035] After aligning the positioning holes of the Z-shaped reinforcing plate and inserting the positioning pin, the upper end face of the support plate 321 can just abut against the lower side of the edge of the Z-shaped reinforcing plate, and the side of the support plate 321 near the support block 2 can just abut against the side of the Z-shaped reinforcing plate away from the support block 2. Then, the clamping arm 323 is rotated until the lower side of the end of the clamping arm 323 near the support block 2 abuts against the edge and side of the Z-shaped reinforcing plate, and the edge and side of the Z-shaped reinforcing plate are clamped and limited by the lower side of the end of the clamping arm 323 near the support block 2 and the support plate 321. With this structure, the clamping member 32 can be used to clamp the edge and side of the Z-shaped reinforcing plate.

[0036] In this embodiment, a linear drive is also included. The linear drive includes a first housing 51 and has an upwardly extending first output shaft 52. The first housing 51 of the linear drive is rotatably connected to the lower side of the connecting plate 322. The free end of the first output shaft 52 is rotatably connected to the end of the clamping arm 323 away from the support plate 321. The middle part of the clamping arm 323 is rotatably connected to the upper side of the connecting plate 322. In this embodiment, the linear drive is a cylinder, which may be model SC160X350S, and the first housing 51 is the cylinder shell.

[0037] In this embodiment: the connecting plate 322 is provided with a drive lug 6 and a clamping lug 7. One end of the drive lug 6 is fixedly connected to the first housing 51, and the other end is hinged to the lower side of the connecting plate 322. One end of the clamping lug 7 is fixedly connected to the middle of the clamping arm 323, and the other end is hinged to the upper side of the connecting plate 322. With this structure, the first housing 51 of the linear drive can be rotatably connected to the lower side of the connecting plate 322, and the middle of the clamping arm 323 can be rotatably connected to the upper side of the connecting plate 322.

[0038] It should be noted that the axes of the three rotation points mentioned above are parallel to each other. The middle part of the clamping arm 323 and the rotation point on the upper side of the connecting plate 322 form a fixed rotation center, allowing the clamping arm 323 to rotate around the fixed rotation center. When the cylinder extends or retracts, the end of the clamping arm 323 away from the support plate 321 moves along an arc trajectory, forcing the clamping arm 323 to rotate around the fixed rotation center. Specifically, when the cylinder extends, the clamping arm 323 rotates around the fixed rotation center closer to the support plate 321; when the cylinder retracts, the clamping arm 323 moves around the fixed rotation center away from the support plate 321.

[0039] In this embodiment, a limiting block 3231 is also provided in the middle of the clamping arm 323. The upper end of the limiting block 3231 is fixedly connected to the clamping arm 323, and the lower end of the limiting block 3231 is recessed upward to form a limiting groove, which can cooperate with the upper part of the connecting plate 322. When the clamping arm 323 rotates to the bottom of the limiting groove and abuts against the upper part of the connecting plate 322, the drive cylinder stops extending further, which can prevent the clamping arm 323 from continuing to press down and damaging the edge and side plate of the Z-shaped reinforcing plate.

[0040] In this embodiment: the linkage includes a first electric push rod and a second electric push rod, both of which are TH-15 models. The support block 2 has a second housing 21 for accommodating the first and second electric push rods. Both the first and second electric push rods are fixedly installed in the second housing 21. The first electric push rod has a second output shaft 411 extending away from the second electric push rod. The free end of the second output shaft 411 is fixedly connected to one of the positioning clamping components. In this embodiment, it is specifically fixedly connected to the mounting plate 31 of one of the positioning clamping components. The second electric push rod has a third output shaft 421 extending away from the first electric push rod. The free end of the third output shaft 421 is fixedly connected to another positioning clamping component. In this embodiment, it is specifically fixedly connected to the mounting plate 31 of another positioning clamping component.

[0041] Simultaneously extending the first and second electric push rods causes the free ends of the second output shaft 411 and the third output shaft 421 to move synchronously away from the support block 2, thus moving the two positioning clamping assemblies away from each other. Conversely, simultaneously shortening the first and second electric push rods causes the free ends of the second output shaft 411 and the third output shaft 421 to move synchronously towards the support block 2, thus moving the two positioning clamping assemblies closer to each other. With this structure, the linkage can be linked with the two positioning clamping assemblies, enabling them to move synchronously closer or further apart.

[0042] In this embodiment: a strip groove 11 is provided on the bracket 1, and the strip groove 11 is arranged along the movement direction of the two positioning clamping components. A slider 8 is fixedly provided on the lower end face of the mounting plate 31, and the slider 8 can slide and fit in the strip groove 11. With this structure, the movement trajectory can be standardized, ensuring the accuracy and stability of the movement of the two positioning clamping components.

[0043] The above are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
