Description

Technical Field

[0001] This utility model relates to the field of rail transit vehicle manufacturing technology, specifically to a positioning fixture for rail transit vehicle doors. Background Technology

[0002] Traditional door positioning fixtures mostly employ fixed structures, making it difficult to adapt to the installation requirements of doors of different sizes. The adjustment process is complex and inefficient. Existing clamps have limited functionality, cannot flexibly adapt to the diverse shapes of door edges, and have limited height adjustment, resulting in insufficient positioning accuracy. Therefore, there is an urgent need for a modular, highly adjustable positioning fixture to improve installation efficiency and versatility. Summary of the Invention

[0003] The purpose of this utility model is to provide a positioning fixture for rail transit vehicle doors, which achieves multi-size adaptation through a socket matrix and replaceable positioning plates, and solves the problem of poor flexibility of traditional fixtures by combining two types of clamps.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A positioning fixture for a rail transit vehicle door is characterized by comprising a support frame and a clamp mounting plate disposed on the support frame. The clamp mounting plate is provided with a plurality of insertion holes arranged in a rectangular array. A positioning plate is adapted to the clamp mounting plate. The positioning plate is provided with round holes and / or oblong holes adapted to the insertion holes. A clamp is mounted on the positioning plate. The positioning plate and the clamp are installed according to the size of the vehicle door.

[0006] The present invention further provides that the clamp includes a first type of clamp and a second type of clamp. The first type of clamp has an L-shaped structure, including a horizontal part and a vertical part. A fixing hole is provided on the horizontal part and a fixing hole is provided on the vertical part. The fixing hole passes through the horizontal part or the vertical part. A snap-fit ​​groove is also provided at the upper end of the vertical part for snapping with the edge of the car door.

[0007] The present invention further includes a base plate, a first side plate, and a second side plate. A perforated plate is provided between the first side plate and the second side plate. The perforated plate has a plurality of openings at different heights for connecting snap-fit ​​components. The snap-fit ​​components are provided with snap-fit ​​grooves.

[0008] The present invention is further provided that the base plate is used to connect the positioning plate, and the side plate one, side plate two, base plate and perforated plate are connected by a tenon and mortise structure.

[0009] The present invention further provides that the first type of clamp is for fixed-height installation; and the second type of clamp is for optional-height installation.

[0010] The beneficial effects of this invention are as follows: This invention, through a combination of a socket matrix and a positioning plate, can quickly adapt to different car door sizes, reducing tooling changeover time. Dual-type clamps: The L-shaped clamp provides rigid fixation, while the second type of clamp allows for stepless height adjustment, covering complex car door structures. Modular design: Each component is detachable and replaceable, reducing maintenance costs. Attached Figure Description

[0014] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0015] like Figure 1 As shown, this utility model is a positioning fixture for a rail transit vehicle door, including a support frame 10 and a clamp mounting plate 20 disposed on the support frame 10. The clamp mounting plate 20 is provided with a plurality of insertion holes 30, which are distributed in a rectangular array. A positioning plate 40 is adapted to the clamp mounting plate 20. The positioning plate 40 has round holes 50 and / or oblong holes adapted to the insertion holes 30. A clamp 70 is installed on the positioning plate 40. The positioning plate 40 and the clamp 70 are installed according to the size of the door.

[0016] The clamp 70 includes a first type of clamp 701 and a second type of clamp 702. The first type of clamp 701 has an L-shaped structure, including a horizontal part 7011 and a vertical part 7012. The horizontal part 7011 has a fixing hole 7013, and the vertical part 7012 has a fixing hole 7013. The fixing hole 7013 passes through the horizontal part 7011 or the vertical part. The upper end of the vertical part 7012 is also provided with a snap-fit ​​groove 7014 for snapping with the edge of the car door.

[0017] The second type of fixture 702 includes a base plate 7021, a first side plate 7022, and a second side plate 7023. A perforated plate 7024 is provided between the first side plate 7022 and the second side plate 7023. The perforated plate 7024 is provided with a plurality of openings 7025 at different heights. The openings 7025 are used to connect a snap-fit ​​component 7026. The snap-fit ​​component 7026 is provided with a snap-fit ​​groove 7014.

[0018] The base plate 7021 is used to connect the positioning plate 40, and the side plate 7022, the side plate 7023, the base plate 7021, and the perforated plate 7024 are connected by a tenon and mortise structure.

[0019] The first type of clamp 701 is for fixed-height installation; the second type of clamp 702 is for optional-height installation.

[0020] This utility model, through the combination of a matrix of insertion holes 30 and a positioning plate 40, can quickly adapt to different car door sizes, reducing tooling changeover time. Dual-type clamps 70: an L-shaped clamp 70 provides rigid fixation, while a second type of clamp 702 allows for stepless height adjustment, covering complex car door structures. Modular design: each component is detachable and replaceable, reducing maintenance costs. It is worth noting that the presence of several clamps in the accompanying drawings does not mean that the clamps in this embodiment are all the same. Figure 1 Instead of placing them, they are arranged and combined according to the specific processing requirements of the car doors.
