Description

Technical Field

[0001] This utility model relates to the technical field of steel structure manufacturing equipment, and in particular to a tooling for controlling the welding precision of the finger plate assembly of a straddle-type single-track turnout beam. Background Technology

[0002] Finger plates are installed on the ends of the straddle-type single-track turnout beam and on the side web of the movable stud beam box girder. The matching position between the turnout beam segment and the stud beam must meet the requirements for flexible track changing of the turnout beam, while also ensuring that the load-bearing capacity of the guide plate position meets the requirements for vehicle operation. The finger plates play an important connecting role between the turnout beam and the stud beam, and the installation accuracy of the finger plates directly affects the reliability of the turnout beam operation.

[0003] Finger plates are typically installed during the fabrication of the web unit. Assembly positions are marked along the longitudinal baseline on the web unit, and the plates are assembled accordingly. However, this current installation method is complex, heavily reliant on the accuracy of the marking and the operator's skill. Furthermore, factors such as welding deformation can lead to inaccuracies in the finger plate's position and parallelism, making it difficult to meet precision requirements. The actual dimensions of the finger plates are not identical after each turnout beam is fabricated, and identical turnout beams are not interchangeable. Utility Model Content

[0004] The purpose of this invention is to provide a precision control tooling for the welding of finger plates of a straddle-type single-track turnout beam, which solves the technical problem of insufficient precision in the assembly of finger plates in the prior art.

[0005] This application discloses a tooling for controlling the welding accuracy of finger plates in a straddle-type single-track turnout beam, including: The first positioning module has multiple first finger-shaped plate positioning grooves spaced apart on one side. The second positioning module is arranged parallel to and spaced apart from the first positioning module, and a plurality of second finger-shaped plate positioning grooves are spaced apart on one side of the second positioning module. A stiffening plate is disposed between the first positioning module and the second positioning module; A limiting plate is positioned between the first positioning module and the second positioning module.

[0006] This application designs a control fixture, which uses multiple components to work together and is positioned using corresponding slots to ensure the accuracy of subsequent assembly.

[0007] Based on the above technical solution, the embodiments of this application can be further improved as follows: Furthermore, the first finger plate positioning groove corresponds one-to-one with the second finger plate positioning groove. The beneficial effect of this step is that by positioning from the top and bottom, the parallelism between the finger plates can be guaranteed, and the accuracy can also be guaranteed.

[0008] Furthermore, the first finger-shaped plate positioning groove and the second finger-shaped plate positioning groove have the same structure and are both trapezoidal grooves; The width of the first finger plate positioning groove is greater than the width of the groove bottom. The advantage of this step is that by designing the groove, it is easier to place and assemble the finger plate.

[0009] Furthermore, there are two stiffening plates, one of which is located at one end of the first positioning module, and the other is located in the middle of the first positioning module; The limiting plate is a single piece, located at the other end of the first positioning module. The advantage of this step is that the stability of the overall structure is ensured by supporting and reinforcing multiple plates.

[0010] Furthermore, one side of the limiting plate extends out from the side where the first finger plate positioning groove of the first positioning module is located. The beneficial effect of this step is to effectively improve the assembly position accuracy of the subsequent finger plates.

[0011] Furthermore, the width of the extending limit plate is not less than 15mm. The beneficial effect of this step is that the specific dimensions can further facilitate subsequent processing.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. This application enables the standardization of finger plate installation for straddle-type single-track turnout beams of the same type, and improves the parallelism between finger plates.

[0013] 2. The tooling of this application can simplify the installation process of finger plates and improve the efficiency of finger plate installation.

[0014] 3. This application can completely avoid the interference problem of the finger plates between the turnout beam segments and the main beam. It reduces the finger plate adjustment process during the dynamic commissioning stage of the turnout beam.

[0015] 4. This application helps to improve the appearance quality of turnout beam segments.

[0016] 5. This application can achieve the installation of different types of finger plates by adjusting the spacing of the positioning slots on the positioning module. Attached Figure Description

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0021] In the description of this application, it should be understood that the terms "upper" and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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 limiting this utility model.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "setup," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0024] Example: like Figure 1-2 As shown in the embodiment of this application, a welding precision control tooling for the finger plate assembly of a straddle-type single-track turnout beam is disclosed. This tooling simplifies the installation of the finger plate during the fabrication of the web plate unit. The finger plate is positioned by its internal slots, thereby ensuring the accuracy of the position and the parallelism of the finger plate.

[0025] Specifically, such as Figure 1 As shown, the structure of this application is as follows, including: The first positioning module 1 has a plurality of first finger-shaped plate positioning grooves 101 spaced apart on one side; The second positioning module 2 is arranged parallel to and spaced apart from the first positioning module 1. A plurality of second finger plate positioning grooves 201 are provided on one side of the second positioning module 2. That is, the first finger plate positioning groove 101 and the second finger plate positioning groove 201 cooperate with each other to facilitate the positioning of the finger plate. The stiffening plate 3 is disposed between the first positioning module 1 and the second positioning module 2; The limiting plate 4 is disposed between the first positioning module 1 and the second positioning module 2.

[0026] To further explain the structure of this application, the tooling in this application consists of the above components. The two positioning modules are arranged in parallel, and the positioning grooves ensure the parallelism of the finger plates, thereby ensuring the accuracy of subsequent processing. Moreover, the spacing between the positioning grooves and the groove opening size in this application are designed according to the actual spacing of the finger plates of the turnout beam.

[0027] To ensure parallelism during subsequent finger plate processing, the first finger plate positioning groove 101 and the second finger plate positioning groove 201 correspond one-to-one.

[0028] To further ensure the processing of the finger-shaped plate, such as Figure 2As shown, this application specifically designs the first finger plate positioning groove 101 and the second finger plate positioning groove 201. The first finger plate positioning groove 101 and the second finger plate positioning groove 201 have the same structure and are both trapezoidal grooves. The groove opening width of the first finger plate positioning groove 101 is greater than the groove bottom width. Specifically, the thickness of the finger plate is t, the top dimension of the groove opening is the finger plate thickness t + 2mm, the bottom dimension of the groove opening is the finger plate thickness t + 7mm, and the groove depth = finger plate height L + 20mm. The grooves need to be cut using wire cutting, and the accuracy must meet the following requirements: single groove width ±0.5mm, groove spacing ±0.5mm, and groove single-sided parallelism 0.5mm. This ensures the accuracy of subsequent finger plate processing.

[0029] The stiffening plate 3 consists of two pieces, one of which is located at one end of the first positioning module 1, and the other is located in the middle of the first positioning module 1. The limiting plate 4 is a single piece, located at the other end of the first positioning module 1, which ensures the stability of the entire mechanism.

[0030] One side of the limiting plate 4 extends out from the side where the first finger plate positioning groove 101 of the first positioning module 1 is located. The width of the extending limiting plate 4 is not less than 15mm. The limiting plate fits against the edge of the turnout beam web plate unit, thereby facilitating the assembly accuracy of the finger plate.

[0031] Further explanation is provided regarding this application: like Figure 3-5 As shown, this application is mainly applied to the finger plate of the straddle-type single-track turnout beam. It is a tooling structure with fewer parts, simple structure, and easy assembly. Moreover, the weight of the entire tooling of this application is no more than 50kg. When using it, you can follow these steps: S1: Lay the web plate unit of the turnout beam segment flat on the welding jig of the web plate unit assembly in the workshop; S2: Install the device of this application at the end of the web plate unit, tighten the limiting plate against the side edge of the web plate unit, and verify the position and size of each finger plate slot; S3: Assemble the finger plates along one straight edge of the first finger plate positioning groove and the second finger plate positioning groove, and spot weld them in place. Assemble all the finger plates in sequence. S4: Remove the welding precision control fixture for the finger plate assembly, and weld the finger plates in sequence.
