Description

Technical Field

[0001] The present application relates to the field of rail vehicle welding tooling, and in particular to a welding positioning tooling for a hand brake shaft of a bogie on a rail vehicle. Background Art

[0002] like Figure 1 The bogie a on the rail vehicle shown in the figure has a frame crossbeam b of a cylindrical structure, and the hand brake shaft c is also a cylindrical structure. The hand brake shaft needs to be welded to a specified position of the frame crossbeam of the bogie, and the welding position of the hand brake shaft needs to match the mounting hole e of the brake hanger d of the bogie. In the existing manufacturing and maintenance process, marking is generally adopted, and then the hand brake shaft is manually clamped for assembly welding. However, it is not easy to find the positioning position when welding the hand brake shaft. At the same time, since the welding position is cylindrical, it is easy to make the welding position incorrect during manual clamping, resulting in failure to install correctly during subsequent assembly. Utility Model Content

[0003] The purpose of the present application is to provide a welding positioning tool for a handbrake shaft of a bogie on a rail vehicle, which facilitates determining the welding position of the handbrake shaft and the frame beam of the bogie, and facilitates keeping the handbrake shaft in the welding position of the frame beam of the bogie.

[0004] In order to achieve the above purpose, this application provides the following technical solutions:

[0005] A welding positioning tool for a hand brake shaft of a bogie on a rail vehicle, comprising a mounting frame, a bushing and a sleeve; a mounting plate is arranged on the upper side of the mounting frame, two bushings are arranged symmetrically mounted on the mounting plate, an extension frame is arranged on the lower side of the mounting frame, and the sleeve is mounted on the end of the extension frame;

[0006] The sleeve has a sleeve hole for accommodating the hand brake shaft, and the two bushings can be inserted into the mounting holes of the brake hanger of the bogie, and the outer periphery of the bushing is provided with threads;

[0007] After the handbrake shaft is inserted into the sleeve hole, the bushing on the mounting frame is inserted into the mounting hole of the brake hanger of the bogie and is locked by a nut in cooperation with the thread, so that the handbrake shaft in the sleeve hole of the bushing remains positioned at the welding position of the frame beam of the bogie.

[0008] Furthermore, a waist-shaped through hole is provided on the upper side of the outer surface of the sleeve, and the waist-shaped through hole corresponds to the oblong hole on the hand brake shaft.

[0009] The beneficial effects of this application are:

[0010] 1. The present application uses two bushings symmetrically mounted on the mounting plate to accurately insert into the mounting hole of the brake hanger of the bogie, thereby ensuring that the hand brake shaft can be accurately positioned at the welding position of the frame crossbeam of the bogie. This positioning method avoids the positioning deviation that may occur during manual clamping and improves the accuracy and reliability of welding.

[0011] 2. After positioning by the tooling, the hand brake shaft can be stably maintained at the welding position of the bogie frame beam, avoiding quality problems caused by position offset during welding. This helps to ensure the strength and sealing of the welding and improve the safety and reliability of rail vehicles.

[0012] 3. Since the tooling can quickly and accurately position the hand brake shaft, it can greatly shorten the preparation time before welding and improve production efficiency. At the same time, due to the improvement of welding quality, it can also reduce the workload of subsequent maintenance and replacement, further reducing production costs.

[0020] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 2 to 4As shown, a welding positioning tool for a hand brake shaft of a bogie on a rail vehicle comprises a mounting frame 1, a bushing 2 and a sleeve 3; a mounting plate 4 is arranged on the upper side of the mounting frame 1, and the mounting plate 4 can be fixed on the mounting frame 1 by welding, and two bushings 2 are arranged symmetrically mounted on the mounting plate 4, and the distance between the two bushings 2 can be set according to the distance between the two mounting holes of the brake hanger of the bogie, and an extension frame 5 is arranged on the lower side of the mounting frame 1, and the sleeve 3 is mounted on the end of the extension frame 5; the sleeve 3 has a sleeve hole 31 for accommodating the hand brake shaft, and the two bushings 2 can be respectively inserted into the two mounting holes of the brake hanger of the bogie, and the outer periphery of the bushing 2 is provided with a thread; after the hand brake shaft is inserted into the sleeve hole 31, the bushing 2 on the mounting frame 1 is inserted into the mounting hole of the brake hanger of the bogie and is locked by a nut 6 with a thread, so that the welding end of the hand brake shaft in the sleeve hole 31 of the bushing 2 is kept positioned at the welding position of the frame crossbeam of the bogie.

[0022] The present application can accurately position the hand brake shaft at the welding position of the frame beam of the bogie through the coordinated use of the mounting frame 1, the bushing 2 and the sleeve 3, and lock and maintain stability through the nut 6. This tooling is not only easy to operate and has strong adaptability, but also can effectively ensure the welding quality, improve production efficiency, and provide a strong guarantee for the safe and reliable operation of rail vehicles.

[0023] like Figure 1 and Figure 2 As shown, a waist-shaped through hole 32 is provided on the upper side of the outer surface of the sleeve 3, and the waist-shaped through hole 32 corresponds to the oblong hole f on the hand brake shaft. The correspondence between the waist-shaped through hole 32 and the oblong hole ensures the correct position of the hand brake shaft in the sleeve 3. This arrangement allows the operator to intuitively confirm whether the shaft is correctly placed by the correspondence between the oblong hole and the waist-shaped through hole 32 when inserting the hand brake shaft into the sleeve 3. This not only improves the convenience of operation, but also greatly reduces welding errors caused by position deviation.
