Description

[0001] This disclosure relates to the field of railway locomotive parts manufacturing, and in particular to a load-bearing positioning device. Background Technology

[0002] With the rapid development of the railway locomotive manufacturing industry, various application scenarios and locomotive models are constantly being enriched. Due to frequent product upgrades, the types of beam structures in the car body steel structure are increasing, and the welding quality control of the beams relies heavily on the guarantee of process equipment. Currently, dedicated tooling is designed for beams of different car models. However, because dedicated tooling is suitable for specific beam structures, it is not interchangeable between different products. This results in significant waste in tooling manufacturing and maintenance, and also increases the consumption of manpower and resources for switching tooling. Therefore, designing a tooling that can be used for beam assembly and welding of various car models while ensuring product quality is particularly important. Summary of the Invention

[0017] Typical embodiments embodying the features and advantages of this disclosure will be described in detail in the following description. It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

[0018] In the following description of various exemplary embodiments of this disclosure, reference is made to the accompanying drawings, which form part of this disclosure, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this disclosure. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this disclosure. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this disclosure, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this disclosure.

[0019] See Figure 1 The illustration shows a perspective view of the load-bearing positioning device proposed in this disclosure. In this exemplary embodiment, the load-bearing positioning device proposed in this disclosure is described using a locomotive body underframe beam as an example. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other types of beams, and these changes are still within the scope of the principles of the load-bearing positioning device proposed in this disclosure.

[0020] like Figure 1 As shown, in one embodiment of this disclosure, the load-bearing positioning device is used to support and position the beam during the welding process of a locomotive beam. The load-bearing positioning device includes a platform 100, multiple support mechanisms 200, a vertical positioning mechanism 300, and multiple lateral positioning mechanisms 400. (See also...) Figures 2 to 6 , Figure 2 A three-dimensional view of the support mechanism 200 is shown in the figure. Figure 3 A perspective view of the first positioning part 410 is shown in the figure. Figure 4 A perspective view of the second positioning part 420 is shown in the figure. Figure 5 A perspective view of the vertical positioning mechanism 300 is shown in the figure. Figure 6 The diagram above represents a typical example of the cooperation between the load-bearing positioning device and the beam. The following, in conjunction with the aforementioned diagram, will provide a detailed description of the structure, connection method, and functional relationship of the main components of the load-bearing positioning device proposed in this disclosure.

[0021] like Figures 1 to 6As shown, in one embodiment of this disclosure, multiple support mechanisms 200 are respectively disposed on the platform 100, and the multiple support mechanisms 200 are arranged at intervals along a first direction parallel to the platform 100, which can be referred to as direction D1 shown in the accompanying drawings. The number of support mechanisms 200 can be, for example, six as shown in the accompanying drawings, or two, three, four, five, seven, or more, which can be flexibly adjusted according to the specific type of beam. Each support mechanism 200 is provided with a support interface 201 extending upward from the platform 100. This support interface 201 is used to support the beam, that is, the support interface 201 can support the bottom of the beam. The support interface 201 can rise and fall relative to the platform 100, thereby pressing against the bottom of the beam. A vertical positioning mechanism 300 is disposed on the platform 100, and the number of vertical positioning mechanisms 300 can be two as shown in the accompanying drawings, or one, three, or more. The vertical positioning mechanism 300 is provided with a pressing interface 301, which is used to press down on the beam, that is, the pressing interface 301 can press against the top of the beam. The pressing interface 301 can move up and down relative to the platform 100, thereby pressing firmly against the top of the beam. Multiple lateral positioning mechanisms 400 are respectively provided on the platform 100, and the multiple lateral positioning mechanisms 400 are spaced apart along a first direction. Each lateral positioning mechanism 400 includes two positioning parts spaced apart in a second direction, which is parallel to the platform 100 and perpendicular to the first direction. The second direction can be referred to as direction D2 shown in the attached figure. The two positioning parts belonging to one lateral positioning mechanism 400 are respectively provided with abutment interfaces 401 on opposite sides, and the abutment interfaces 401 of these two positioning parts are respectively used to abut against the two sides of the beam in the second direction. Specifically, the two positioning parts belonging to a lateral positioning mechanism 400 are a first positioning part 410 and a second positioning part 420. The abutment interface 401 of the first positioning part 410 is relatively fixed, while the abutment interface 401 of the second positioning part 420 can extend and retract in a second direction, so that the two abutment interfaces 401 are respectively pressed against both sides of the beam. Through the above design, this disclosure can make the support interface 201 of the support mechanism 200 press against the bottom of the beam by adjusting the lifting of the support interface 201; can make the pressing interface 301 of the vertical positioning mechanism 300 press against the top of the beam by adjusting the lifting of the pressing interface 301; and can make the two abutment interfaces 401 of the two positioning parts of the lateral positioning mechanism 400 press against both sides of the beam by adjusting the lateral movement of the abutment interface 401. Accordingly, this disclosure realizes a positioning and bearing function with dual degrees of freedom in the width and height directions of the beam. While satisfying the positioning function, it can be applied to beams of various models and specifications, without being limited by changes in beam size.Compared to traditional solutions, this disclosure reduces the number of tooling components, lowers the manufacturing and maintenance costs of tooling, and only requires adjustment of the aforementioned adjustable components when switching between different products, thus shortening the conversion cycle, improving the welding efficiency of the beam, and ensuring high manufacturing quality.

[0022] Specifically, by adjusting the support interface 201 of the support mechanism 200, this disclosure can adjust the support height of the support mechanism 200 for beams of different specifications, and can also prefabricate different support heights at different locations, that is, adjust the support mechanism 200 at different locations individually. Since beam welding deformation is difficult to control, relying solely on traditional positioning and clamping fixtures after welding is insufficient to guarantee the flatness and straightness of the beam. Therefore, different beams can have their anti-deformation positions and anti-deformation amounts prefabricated through the support mechanism 200. Continuing from the above, with... Figure 6 Taking the illustrated application scenario as an example, the channel steel 900 of the crossbeam can be placed on the support mechanism 200. The height of the support point in the middle region of the channel steel 900 along the first direction is 5mm higher than the height of the support points at the two lower ends. That is, the height of the support interface 201 of the two support mechanisms 200 located in the middle region is 5mm higher than the height of the support interface 201 of the other support mechanisms 200. Based on this, the anti-deformation amount is pre-made to ensure the straightness of the beam after welding. Furthermore, by adjusting the abutment interface 401 of the second positioning part 420, this disclosure can adjust the clamping amount of the transverse positioning mechanism 400 for beams of different specifications, and can also pre-make different clamping amounts at different positions. That is, the transverse positioning mechanism 400 at different positions can be adjusted individually. Through this method, a certain anti-deformation is made to the beam in the second direction to ensure the flatness of the beam after welding. In addition, by adjusting the pressing interface 301 of the vertical positioning mechanism 300, this disclosure can control the deformation of the beam in the height direction.

[0023] It should be noted that, in the above description, the term "bottom of the beam" is not limited to the bottom of the beam after assembly and welding or in the application scenario (e.g., when installed on a locomotive). Figure 6 As shown, taking a beam including channel steel 900 and a cover plate as an example, the load-bearing positioning device proposed in this disclosure can be used to support and position the channel steel 900 of the beam. During the process of being supported, positioned, and welded, the channel steel 900 is in a "lying" state, meaning the "groove opening" of the channel steel 900 faces the horizontal direction, for example, towards the second positioning part 420 as shown in the attached figure, and the "groove bottom" of the channel steel 900, which is the actual bottom of the beam, faces the horizontal direction, for example, towards the first positioning part 410 as shown in the attached figure. At this time, the support interface 201 of the support mechanism 200 supports one side of the "groove wall" of the channel steel 900, which is the so-called "bottom of the beam" described above. Furthermore, the so-called "top of the beam" in the above description is not limited to the top of the beam after welding or in the application scenario; for example, it could be... Figure 6The vertical positioning mechanism 300's pressing interface 301 is shown pressing against the other side of the channel steel 900, which is the "top of the beam" mentioned above. Furthermore, in the above description, the abutment interfaces 401 of the two positioning parts abut against the two sides of the beam in the second direction, which can be understood as... Figure 6 The abutment interfaces 401 of the two positioning parts shown abut against the "groove opening" side (e.g., the abutment interface 401 of the second positioning part 420 abuts against this side) and the "groove bottom" side (e.g., the abutment interface 401 of the first positioning part 410 abuts against this side) of the channel steel 900.

[0024] In one embodiment of this disclosure, the surface of the platform 100 may be machined to ensure the flatness of the platform 100 surface and eliminate the tooling errors during the assembly and welding of the beam.

[0025] like Figure 2 As shown, in one embodiment of this disclosure, the support mechanism 200 may include a support base 210, a support screw 220, and a locking nut 230. Specifically, the support base 210 is disposed on the platform 100, and the support base 210 is provided with a screw hole extending in a vertical direction, the screw hole opening at the top of the support base 210. The support screw 220 is disposed in the screw hole of the support base 210, and the support screw 220 is threadedly engaged with the screw hole. The top surface of the nut portion 221 of the support screw 220 forms the aforementioned support interface 201; in other words, the support mechanism 200 supports the beam body with the top surface of the nut portion 221 of the support screw 220. The locking nut 230 is sleeved on the support screw 220 and threaded together, thereby achieving adjustable locking of the support screw 220 and the support base 210. For example, by tightening the locking nut 230, the height of the support screw 220 can be adjusted, thereby changing the height of the support interface 201 relative to the platform 100. The locking nut 230 also provides a self-locking function for the support screw 220. Through the above design, this disclosure utilizes the support screw 220 and the locking nut 230 to specifically realize the lifting function of the support mechanism 200 and the support interface 201. The structure is simple, the cost is low, and it is easy to process and assemble. Furthermore, by tightening the support screw 220 to achieve the lifting of the support interface 201, the adjustment of the support interface 201 has higher precision and greater freedom. In other embodiments of this disclosure, the support mechanism 200 can adopt other specific liftable support structures, and can employ an automatic lifting scheme based on mechanisms such as telescopic cylinders and telescopic rods.

[0026] like Figure 1As shown, in one embodiment of this disclosure, the number of support mechanisms 200 may be greater than the number of lateral positioning mechanisms 400. Based on this, some support mechanisms 200 are arranged in a one-to-one correspondence with multiple lateral positioning mechanisms 400. For example, four of the six support mechanisms 200 shown in the figures are arranged in a one-to-one correspondence with the four lateral positioning mechanisms 400. Through the above design, this disclosure ensures that the beam is supported at its bottom by support mechanisms 200 at each lateral positioning position, further ensuring the stability of each lateral positioning mechanism 400 when adjusted (e.g., adjusting the lateral movement of the abutment interface 401). In other embodiments of this disclosure, the number of support mechanisms 200 may also be equal to the number of lateral positioning mechanisms 400. Based on this, multiple (e.g., all) support mechanisms 200 are arranged in a one-to-one correspondence with multiple lateral positioning mechanisms 400, and this is not limited to this embodiment.

[0027] like Figure 1 As shown, based on the structural design that at least some of the support mechanisms 200 are arranged in a one-to-one correspondence with the lateral positioning mechanisms 400, in one embodiment of this disclosure, along the second direction, the support mechanisms 200 arranged corresponding to the lateral positioning mechanisms 400 can be arranged close to the first positioning part 410. In other words, for the correspondingly arranged lateral positioning mechanisms 400 and support mechanisms 200, along the second direction, the distance between the support mechanism 200 and the first positioning part 410 in the lateral positioning mechanism 400 can be less than the distance between the support mechanism 200 and the second positioning part 420. Through the above design, since the abutment interface 401 of the second positioning part 420 adopts a telescopic and adjustable design, the support mechanism 200 is arranged close to the first positioning part 410, which can reserve more space for the telescopic adjustment of the abutment interface 401 of the second positioning part 420, making the application range of the bearing positioning device wider. For example, it can be used for beams with larger dimensions in the second direction (specifically, it can be a channel steel 900 with a larger channel wall height). When applied to beams with smaller dimensions in the second direction, it avoids the problem that the support interface 201 cannot fully support the bottom of the beam because the support mechanism 200 is too close to the second positioning part 420.

[0028] like Figure 1 As shown, in one embodiment of this disclosure, the relative positions of the plurality of support mechanisms 200 in the second direction can be roughly correspondingly arranged, that is, the plurality of support mechanisms 200 are arranged at intervals along a straight line path parallel to the first direction. Through the above design, this disclosure can simplify structural complexity and reduce processing difficulty and production costs. In an embodiment not shown in this disclosure, at least two support mechanisms 200 can be staggered along the second direction, thereby improving the stability of the support mechanism 200 when bearing the beam. This can be selected as needed and is not limited to the above embodiments.

[0029] like Figure 1 and Figure 3As shown, in one embodiment of this disclosure, the first positioning part 410 may include a positioning plate 411. The positioning plate 411 is disposed on the platform 100, and its thickness direction is arranged parallel to the first direction; in other words, the positioning plate 411 faces the second positioning part 420 (i.e., the beam body) with its edge surface facing it. Based on this, the aforementioned abutment interface 401 can be formed on the side edge of the positioning plate 411 facing the second positioning part 420. Through the above design, this disclosure utilizes the positioning plate 411 as the first positioning part 410, resulting in a simple structure, low cost, and ease of processing and assembly.

[0030] like Figure 3 As shown, based on the design of the first positioning part 410 including the positioning plate 411, in one embodiment of this disclosure, two abutting protrusions 412 may be provided on the edge of the positioning plate 411 facing the second positioning part 420. These two abutting protrusions 412 are arranged at intervals in the vertical direction. Based on this, the end faces of the two abutting protrusions 412 facing the second positioning part 420 respectively form the abutting interface 401 of the first positioning part 410. Through the above design, this disclosure utilizes the two abutting protrusions 412 to form two abutting interfaces 401 on the positioning plate 411, thereby achieving "two-point" positioning of the positioning plate 411 on one side of the beam. Taking channel steel 900 as an example, the bottom wall of channel steel 900 (i.e., the "bottom of the channel" mentioned above) may have poor flatness. That is, the surface of channel steel 900 that contacts the abutment interface 401 of the first positioning part 410 may have a certain curvature. This disclosure utilizes the "two-point" positioning design, which is suitable for the abutment of channel steel 900 in the above situation, ensuring a stable positioning effect and ensuring the quality of welding assembly.

[0031] like Figure 4 As shown, in one embodiment of this disclosure, the second positioning part 420 may include a base 421, a guide block 422, a guide rod 423, and a pressure plate 424. Specifically, the base 421 is disposed on the platform 100. The guide block 422 is disposed on the base 421, and a guide hole is provided with a guide hole extending in a second direction. The guide rod 423 passes through the guide hole, and the guide rod 423 can extend and retract relative to the guide block 422 in the second direction. The pressure plate 424 is located on the side of the guide block 422 near the first positioning part 410, and the pressure plate 424 is connected to the guide rod 423. Based on this, the surface of the pressure plate 424 facing the first positioning part 410 forms the abutment interface 401 of the second positioning part 420. Through the above design, this disclosure utilizes the pressure plate 424 to abut against the beam, which can increase the contact area with the beam, make the beam more evenly stressed, improve the positioning effect, and ensure the welding quality.

[0032] like Figure 4As shown, based on the design of the second positioning part 420 including guide blocks 422, in one embodiment of this disclosure, the second positioning part 420 may include at least two guide blocks 422, such as, but not limited to, the two guide blocks 422 shown in the figures, and these guide blocks 422 are arranged at intervals along the second direction. Through the above design, this disclosure utilizes at least two guide blocks 422 to cooperate with the guide rod 423. On the one hand, the guide holes of at least two guide blocks 422 can be used to guide the guide rod 423 together, ensuring a better guiding effect. On the other hand, the portion of the guide rod between the two guide blocks 422 can be exposed for easy observation, and material costs can also be reduced.

[0033] like Figure 4 As shown, based on the design of the second positioning part 420 including the guide block 422, in one embodiment of this disclosure, the guide block 422 may be provided with two guide holes, which are arranged at intervals along the vertical direction. Correspondingly, the second positioning part 420 may include two guide rods 423, which are respectively inserted through the two guide holes and respectively connected to the pressure plate 424. Through the above design, this disclosure utilizes the cooperation of the two guide rods 423 and the two guide holes to ensure the stability of the guide rods 423 when moving along the second direction, avoids deflection, improves the positioning effect when the guide rods 423 drive the pressure plate 424 to press against the beam, and ensures the welding quality.

[0034] Based on the design of the guide hole and guide rod 423, in one embodiment of this disclosure, the guide hole can be a threaded hole, and correspondingly, the guide rod 423 can be a screw, which passes through the threaded hole and is screwed in. Through the above design, this disclosure utilizes the screw and threaded hole to specifically realize the translational and telescopic functions of the guide rod 423, the pressure plate 424, and the abutment interface 401. The structure is simple, the cost is low, and it is easy to process and assemble. Furthermore, by turning the screw to realize the translational and telescopic functions of the abutment interface 401, the telescopic adjustment of the abutment interface 401 has higher precision and degree of freedom. In other embodiments of this disclosure, the second positioning part 420 can adopt other specific translational and telescopic positioning structures, and can adopt an automatic telescopic scheme based on mechanisms such as telescopic cylinders and telescopic rods.

[0035] like Figure 4As shown, based on the design of the second positioning part 420 including a base 421 and a guide hole, in one embodiment of this disclosure, the second positioning part 420 may further include two reinforcing side plates 425. The reinforcing side plates 425 are disposed on the base 421, and the two reinforcing side plates 425 are respectively connected to both sides of the guide block 422 in the first direction. Through the above design, this disclosure can strengthen the connection strength between the base 421 and the guide block 422. Furthermore, when the second positioning part 420 includes at least two guide blocks 422, a single reinforcing side plate 425 can simultaneously connect to at least two guide blocks 422, thereby strengthening the structural integrity between the at least two guide blocks 422, thus ensuring the stability of the guide channel formed by the guide holes of the at least two guide blocks 422 and its cooperation with the guide rod 423, and ensuring the stability of the telescopic translation of the guide rod 423.

[0036] like Figure 1 As shown, in one embodiment of this disclosure, the plurality of first positioning portions 410 of the plurality of lateral positioning mechanisms 400 may be located on the same side along the second direction, and the plurality of second positioning portions 420 may be located on the same other side along the second direction. Wherein, Figure 6 Taking the channel steel 900 shown as an example, when the channel steel 900 is laid down and supported by the positioning device, its two sides in the second direction are respectively the "bottom of the channel" and the "mouth of the channel". Based on this, this disclosure arranges multiple first positioning parts 410 on the same side in the second direction, that is, the "bottom of the channel" side. The abutment interface 401 of the first positioning part 410 can be used to position this side of the channel steel 900. Specifically, the two abutment protrusions 412 of the first positioning part 410 abut against the bottom wall of the channel steel 900. Furthermore, this disclosure arranges multiple second positioning parts 420 on the same side in the second direction, that is, the "mouth of the channel" side. The abutment interface 401 of the second positioning part can be used to position this side of the channel steel 900. Specifically, the pressure plate 424 of the second positioning part 420 abuts against the "mouth of the channel steel 900", which is actually abutting against the end of the side wall of the channel steel 900 away from the bottom wall. Among them, using the pressure plate 424 to abut against the end of the side wall is more reliable, because if the abutment protrusion 412 is used to abut against the end of the side wall, there may be a problem that the abutment protrusion 412 falls within the range of the "groove" and cannot accurately abut against the end of the side wall.

[0037] Based on the design that the first positioning parts 410 of multiple lateral positioning mechanisms 400 are located on the same side along the second direction, in one embodiment of this disclosure, the abutment interfaces 401 of all the first positioning parts 410 can be located on the same plane. Through the above design, this disclosure can ensure the position of the channel steel 900 and the cover plate of the beam.

[0038] like Figure 1As shown, in one embodiment of this disclosure, the vertical positioning mechanism 300 can be disposed on the horizontal positioning mechanism 400, that is, the vertical positioning mechanism 300 is indirectly disposed on the platform 100 via the horizontal positioning mechanism 400. Through the above design, compared to directly disposing of the vertical positioning mechanism 300 on the platform 100, this disclosure simplifies structural complexity, reduces the number of parts, and helps to reduce costs. In other embodiments of this disclosure, the vertical positioning mechanism 300 can also be directly disposed on the platform 100, or a portion of the vertical positioning mechanism 300 can be directly disposed on the platform 100, while another portion can still be disposed on the horizontal positioning mechanism 400; these are not limited to this embodiment.

[0039] like Figure 1 As shown, based on the design of the vertical positioning mechanism 300 being disposed on the horizontal positioning mechanism 400, in one embodiment of this disclosure, the number of vertical positioning mechanisms 300 may be less than the number of horizontal positioning mechanisms 400. For example, but not limited to, two of the four horizontal positioning mechanisms 400 shown in the figures may each be provided with a vertical positioning mechanism 300. Furthermore, except for the horizontal positioning mechanism 400 located at the ends in the first direction, the remaining horizontal positioning mechanisms 400 may each be provided with a vertical positioning mechanism 300. Through the above design, this disclosure utilizes the special distribution of the vertical positioning mechanisms 300 to ensure that at least the middle region of the beam in the first direction can be positioned by the vertical positioning mechanism 300, thereby cooperating with the support mechanism 200 to jointly achieve vertical positioning of the beam. Furthermore, since the horizontal positioning mechanisms 400 at both ends are not provided with vertical positioning mechanisms 300, this disclosure can reduce the number of parts, which is beneficial for cost reduction.

[0040] like Figure 5 As shown, based on the design of the vertical positioning mechanism 300 being disposed on the horizontal positioning mechanism 400, in one embodiment of this disclosure, the vertical positioning mechanism 300 may include a frame 310 and a pressure rod 320. Specifically, the frame 310 is disposed on the top of the second positioning part 420, and one end of the frame 310 extends along a second direction above the gap between the first positioning part 410 and the second positioning part 420, that is, above the area between the first positioning part 410 and the second positioning part 420 for placing the beam. The pressure rod 320 is vertically and flexibly disposed at the end of the frame 310, and a pressing block 321 is provided at the lower end of the pressure rod 320, the bottom surface of which forms the aforementioned pressing interface 301 of the vertical positioning mechanism 300. In other embodiments of this disclosure, the vertical positioning mechanism 300 (e.g., the frame 310) may also be disposed on the top of the first positioning part 410, and is not limited to this embodiment.

[0041] In one embodiment of this disclosure, the bearing positioning device further includes a positioner disposed at the bottom of the platform 100 for driving the platform 100 to move, such as by translation, lifting, or rotation, thereby enabling the bearing positioning device to move between different production and processing stations.

[0042] It should be noted that the load positioning devices shown in the accompanying drawings and described in this specification are merely a few examples among many load positioning devices capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the load positioning devices shown in the accompanying drawings or described in this specification.

[0043] In summary, the bearing positioning device proposed in this disclosure includes multiple support mechanisms 200, a vertical positioning mechanism 300, and multiple lateral positioning mechanisms 400; the multiple support mechanisms 200 are arranged at intervals along a first direction; each support mechanism 200 is provided with a support interface 201 extending upward from the platform 100 and used to support the beam, and the support interface 201 can rise and fall relative to the platform 100; the vertical positioning mechanism 300 is provided with a pressing interface 301 for pressing down on the beam, and the pressing interface 301 can rise and fall relative to the platform 100; the multiple lateral positioning mechanisms 400 are arranged at intervals along the first direction; each lateral positioning mechanism 400 includes two positioning parts arranged at intervals along a second direction; each of the two positioning parts has a contact interface 401 for abutting against the beam on its opposite side, and the two positioning parts are a first positioning part 410 and a second positioning part 420, respectively, the contact interface 401 of the first positioning part 410 is relatively fixed, and the contact interface 401 of the second positioning part 420 can extend and retract along the second direction. Through the above design, this disclosure enables the support interface 201 of the lifting and adjusting support mechanism 200 to be pressed tightly against the bottom of the beam; the pressing interface 301 of the vertical positioning mechanism 300 to be pressed tightly against the top of the beam; and the abutting interface 401 of the second positioning part 420 to be pressed tightly against both sides of the beam by adjusting the horizontal movement of the two abutting interfaces 401 of the two positioning parts of the horizontal positioning mechanism 400. Accordingly, this disclosure achieves a positioning and bearing function with dual degrees of freedom in the width and height directions of the beam. While fulfilling the positioning function, it is applicable to beams of various vehicle models and specifications, and is not limited by changes in beam dimensions. Compared to traditional solutions, this disclosure reduces the number of tooling components, lowers tooling manufacturing and maintenance costs, and only requires adjustment of the aforementioned adjustable components when switching between different products, shortening the conversion cycle, improving beam assembly and welding efficiency, and ensuring high manufacturing quality.
