[0024] Some parts of rail vehicles are large in size and heavy in weight, especially those assembled at the bottom of the car. It is difficult to use equipment such as cranes, and the assembly operation requires a lot of manpower and time. In the related technology, the anti-roll torsion bar of rail vehicles is an important part of the bogie system, which is mainly used to suppress the rolling movement of the car body, thereby improving the comfort of passengers. The anti-roll torsion bar is fixed to the bottom of the bogie frame through two friction rubber sleeves distributed at both ends, and is connected to the car body through two connecting rods. If the car body rolls, the anti-roll torsion bar will be twisted. The twisting process of the anti-roll torsion bar offsets the rolling movement of the car body and plays a role in slowing down the rolling of the car body. The anti-roll torsion bar is a key component for the safety of rail vehicle driving, so the anti-roll torsion bar should be inspected at certain intervals. If the anti-roll torsion bar has permanent deformation, cracks or node rupture, the anti-roll torsion bar needs to be replaced to ensure that the anti-roll torsion bar is within the normal use range and to ensure the safe operation of the train. When the inspection value of the anti-roll torsion bar is abnormal, the anti-roll torsion bar needs to be replaced. Currently, the replacement work requires the cooperation of at least 4 workers. After removing the anti-roll torsion bar installation bolts, two workers use clamps on both sides to compress the two friction rubber sleeves on the left and right of the anti-roll torsion bar. When the friction rubber sleeves are completely compressed by the clamps, two workers remove the anti-roll torsion bar, which consumes a lot of manpower and time. In addition, during the replacement of the anti-roll torsion bar, the anti-roll torsion bar may fall, causing damage to personnel and equipment, and posing a safety hazard.

[0025] It can be understood that the embodiment of the first aspect of the present invention proposes an assembly tool for rail vehicles, which is an auxiliary equipment dedicated to the manufacture and maintenance of rail vehicles. Its core function is to provide efficient and stable assembly support, especially when installing components on the bottom of the car body, which can significantly reduce the labor intensity of workers and improve work efficiency.

[0026] Reference Figure 7 The assembly tooling of the rail vehicle includes a horizontal base 100, two cylinders 200 and an air delivery assembly 300, wherein the horizontal base 100 is the basic support structure of the assembly tooling, and its design must ensure sufficient stability and load-bearing capacity. The horizontal base 100 is usually made of high-strength metal material, and has the characteristics of high strength and wear resistance to adapt to the complex environment of the rail vehicle manufacturing site. The shape and size of the horizontal base 100 must be accurately calculated to ensure that both ends can be stably placed on the rails 140, maintain the horizontal state of the entire tooling, and provide a stable platform for subsequent assembly operations. In addition, the bottom surface of the horizontal base 100 can be provided with an anti-slip texture or an anti-slip device to prevent sliding during operation and ensure operation safety, or a buckle can be provided on the bottom surface of the horizontal base 100 to fix it on the rails 140 to provide a more stable support foundation.

[0027] The assembly tool is equipped with two cylinders 200, which are installed at both ends of the horizontal base 100, and the cylinders 200 are arranged vertically, aiming to use the vertical extension and contraction of the cylinders 200 to realize the lifting and lowering of the components on the fixture mounting plate 210. By replacing cylinders 200 of different specifications, the stroke of 0 to 1000 mm can be met. The cylinder 200 is a high-performance pneumatic component with the characteristics of fast response, high thrust output and low maintenance cost. The fixture mounting plate 210 is a connecting component at the upper end of the cylinder 200, which is used to install and fix various special fixtures. The fixture is customized according to the shape and size of the components to be assembled to ensure that the components can be accurately positioned. The design of the fixture mounting plate 210 has sufficient rigidity and flexibility, which can not only ensure the stability of the fixture, but also facilitate the rapid replacement of different fixtures to adapt to different assembly tasks. For example, four holes for bolt installation are opened on the fixture mounting plate 210 to facilitate the fixing of the fixture.

[0028] The gas delivery assembly 300 is a key part connecting the external gas source and the cylinder 200, including a switch valve 310 and two control valves 320. The switch valve 310 is responsible for controlling the on-off of the gas circuit of the entire system to ensure safety and flexibility during operation. The control valve 320 is responsible for adjusting the flow direction and pressure of the gas. Each control valve 320 is connected to a corresponding cylinder 200. The control valve 320 has an intake pipe 321, an air delivery pipe 322 and a return pipe 323. The intake pipe 321 is connected to the switch valve 310 to introduce the high-pressure gas from the external gas source into the control valve 320; the air delivery pipe 322 delivers the gas to the piston chamber of the cylinder 200 to drive the piston to move; the return pipe 323 is responsible for returning the gas discharged from the cylinder 200 to the outside of the system to form a complete gas circuit.

[0029] The working principle of the assembly tooling of rail vehicles is based on pneumatic transmission technology, which achieves precise control of the cylinder 200 by controlling the flow and pressure of gas. When the switch valve 310 is opened, the high-pressure gas from the external gas source enters the control valve 320 through the intake pipe 321. According to the work requirements, the operator adjusts the flow direction of the gas through the control valve 320, so that the gas enters the lower chamber or the upper chamber of the cylinder 200, pushing the piston upward or downward. The movement of the piston drives the fixture mounting plate 210 and the components thereon to rise and fall, thereby realizing the lifting and positioning of the components for easy assembly.

[0030] The operation of the assembly tooling for rail vehicles is as follows: 1. Tool positioning: Place both ends of the horizontal base 100 steadily on the rails, adjust to a horizontal state, and ensure a stable position. 2. Connect the gas source: Connect the switch valve 310 of the gas transmission component 300 to the external gas source to ensure a stable gas supply. 3. Turn on the gas source: Open the switch valve 310 to allow high-pressure gas to enter the gas transmission component 300. 4. Adjust the control valve 320: According to the assembly requirements, operate the control valve 320 to allow gas to enter the corresponding chamber of the cylinder 200, and the cylinder 200 drives the fixture mounting plate 210 to rise. 5. Component assembly: Under the push of the cylinder 200, lift the components on the fixture mounting plate 210 to a suitable height for workers to use for assembly operations.

[0031] The assembly tooling for rail vehicles has greatly improved the efficiency and accuracy of assembly operations and reduced labor and time costs. Through pneumatic transmission technology, the rapid lifting and precise positioning of components are achieved, which reduces the manual operation of workers and reduces labor intensity. In addition, the design of the tooling fully considers safety and flexibility, and can be adjusted according to different vehicle models and assembly requirements, with strong versatility. In the field of rail vehicle manufacturing, maintenance and modification, the tooling has become an indispensable and efficient tool, making a significant contribution to improving production efficiency and product quality.

[0032] It should be understood that the assembly tooling for a rail vehicle can be used to assemble various components of a rail vehicle, and the following description will be given using the assembly of the anti-roll torsion bar 500 as an example.

[0033] Reference Figures 1 to 6 The second embodiment of the present invention provides an anti-roll torsion bar disassembly and assembly auxiliary device, including the assembly tool and the clamp 400 of the first embodiment. The anti-roll torsion bar disassembly and assembly auxiliary device is provided with a clamp 400 specially adapted for the anti-roll torsion bar 500 on the basis of the assembly tool.

[0034] The main body of the clamp 400 is composed of a solid bottom plate 410. The bottom plate 410 serves as the basic support structure of the entire clamp 400 to ensure stability and reliability during assembly and disassembly. The bottom plate 410 is fixed to the mounting plate 210 of the clamp 400 by four bolts. A bracket 420 and a push frame 430 are respectively designed at both ends of the bottom plate 410. Figure 2 As shown, the anti-roll torsion bar 500 includes a round rod 510 and friction rubber sleeves 520 distributed at both ends of the round rod 510. The round rod 510 is placed on two brackets 420. The brackets 420 are provided with semicircular grooves that match the round rod 510 to accurately position the anti-roll torsion bar 500 to prevent it from falling due to shaking or tilting during the disassembly and assembly process, thereby avoiding injuries to workers and equipment.

[0035] The push frame 430 is located at one end of the bottom plate 410 away from the gas delivery assembly 300, and is intended to compress the friction rubber sleeve 520 of the anti-roll torsion bar 500 through mechanical force. One or more compression push rods 440 are connected to the push frame 430, and the compression push rods 440 are usually high-strength metal parts to ensure sufficient rigidity and durability. The compression push rods 440 directly act on the friction rubber sleeve 520 of the anti-roll torsion bar 500 to achieve compression of the friction rubber sleeve 520. For example, the compression push rod 440 uses a bolt, and the push frame 430 is provided with a matching threaded hole. By screwing the bolt to apply thrust to the friction rubber sleeve 520, a pressing sheet can be provided at the end of the bolt to increase the contact area. Alternatively, the compression push rod 440 uses an automatic drive mechanism (such as an electric push rod, a cylinder, etc.) to generate thrust to achieve compression of the friction rubber sleeve 520, thereby creating necessary space conditions for the disassembly and assembly of the anti-roll torsion bar 500.

[0036] Operation process of the anti-roll torsion bar disassembly and assembly auxiliary device: Reference Figure 1 First, place the anti-roll torsion bar 500 steadily on the brackets 420 of the two clamps 400 to ensure that both ends of the anti-roll torsion bar 500 are stably supported. By operating the compression push rod 440, the friction rubber sleeves 520 at both ends of the anti-roll torsion bar 500 are appropriately compressed by the thrust generated by the compression push rod 440. Then, connect the switch valve 310 of the gas transmission component 300 to the external gas source, which is usually the gas tank 150 in the car, and input high-pressure gas to the cylinder 200. The cylinder 200 pushes the clamp 400 and the anti-roll torsion bar 500 to the installation position as a whole. Only one worker is needed to complete the installation of the anti-roll torsion bar 500. The cooperation of two people is more efficient and further saves time.

[0037] The process of disassembling the anti-roll torsion bar 500 is opposite to the assembly process. The cylinder 200 pushes the clamp 400 up to the position of supporting the anti-roll torsion bar 500. By operating the compression push rod 440, the thrust generated by it is used to appropriately compress the friction rubber sleeves 520 at both ends of the anti-roll torsion bar 500, and then the connection structure between the anti-roll torsion bar 500 and the car body is disassembled. The control valve 320 is operated, and the cylinder 200 drives the clamp 400 and the anti-roll torsion bar 500 to descend.

[0038] The technical effects of the anti-roll torsion bar disassembly and assembly auxiliary device include: 1. Greatly reducing the manpower and time costs, shortening the time spent on disassembly and assembly. 2. Reducing the labor intensity of workers. The anti-roll torsion bar 500 is supported by the clamp 400, and the cylinder 200 provides the lifting force. Workers do not need to support the anti-roll torsion bar 500, reducing fatigue. 3. Eliminating safety risks: avoiding accidental injuries that may be caused by direct manual operation, such as the anti-roll torsion bar 500 falling, etc., ensuring the safety of workers and equipment.

[0039] Reference Figure 3In some embodiments of the present invention, a two-position five-way manual valve is used as the control valve 320. The manual valve is used in the fields of industrial automation and pneumatic control, and is widely used because of its compact structure, simple operation and high reliability.

[0040] The two-position five-way manual valve has five interfaces, namely, an input port, an air delivery port, an air return port and two exhaust ports. Among them, the input port is connected to the air inlet pipe 321, which is responsible for introducing high-pressure gas into the two-position five-way manual valve. The air delivery port is connected to the air delivery pipe 322, and when the air return port is connected to the air return pipe 323, it is responsible for guiding the exhaust gas of the cylinder 200 to the exhaust port and discharging it to the outside. When the clamp 400 rises, the two-position five-way manual valve is in a forward working state, and the gas at the input port will be guided to the air delivery port, and then transported to the lower chamber of the cylinder 200 through the air delivery pipe 322, pushing the piston up, and the air in the upper chamber is discharged through the air return pipe 323 and one of the exhaust ports. When the clamp 400 descends, by operating the two-position five-way manual valve, it is converted to a reverse working state, and the gas at the input port will be guided to the air return port, and then transported to the upper chamber of the cylinder 200 through the air return pipe 323, pushing the piston down, and the air in the lower chamber is discharged through the air delivery pipe 322 and another exhaust port. The rise and fall of the cylinder 200 can be controlled by operating the two-position five-way manual valve.

[0041] In addition, the control valve 320 may also be an electrically controlled valve, which can electrically control the movement of the cylinder 200, and can also achieve controllable rise and fall of the clamp 400 and the anti-roll torsion bar 500.

[0042] It is understandable that an air locking valve 330 is provided on the air supply pipe 322, through which the air locking valve 330 can lock the air pressure in the lower chamber of the cylinder 200 to prevent the cylinder 200 from suddenly falling due to insufficient air pressure, thereby preventing the anti-roll torsion bar 500 from hitting the workers and improving safety.

[0043] Furthermore, the exhaust port of the two-position five-way manual valve is equipped with a muffler 324, which effectively reduces noise pollution during use, thereby creating a more comfortable and safe working environment. As an effective noise control device, the muffler 324 is usually filled with sound-absorbing materials, such as porous metal, glass fiber or foam plastic, which can absorb or reflect sound waves, thereby significantly reducing exhaust noise. The muffler 324 is fixed to the two-position five-way manual valve by threaded connection or flange connection.

[0044] The switch valve 310 adopts a hand slide valve, which is widely used in the field of pneumatic control due to its easy operation, sensitive response and strong durability. The design of the hand slide valve allows the operator to open and close the valve with a simple sliding action, thereby improving work efficiency.

[0045] An air pipe quick connector 311 is provided at the upper end of the hand slide valve to facilitate connection to an external air source. The air pipe quick connector 311 is a device for quickly connecting and disconnecting the air pipe, and its design makes the air pipe easier to disassemble and assemble. In actual operation, the operator does not need to use tools, and can simply insert the air pipe into the quick connector to complete the connection. A three-way connector 312 is provided at the lower end of the hand slide valve for connecting two control valves 320 respectively. The three-way connector 312 enables the hand slide valve to output high-pressure gas to the two control valves 320 at the same time, thereby realizing the coordinated control of multiple components in the assembly tooling.

[0046] Reference Figure 4 The cylinder 200 serves as the main driving component of the assembly tooling. The upper end of its piston rod 220 is fixedly connected to the center or preset position of the mounting plate 210 of the fixture 400 through fasteners or other reliable connection methods. When the piston rod 220 moves, it can drive the mounting plate 210 of the fixture 400 to move synchronously, thereby realizing the positioning or clamping operation during the assembly process.

[0047] A guide rod 230 is fixedly connected to both ends of the mounting plate 210 of the clamp 400. A guide groove 240 is provided on the side wall or at an appropriate position of the cylinder 200. The shape and size of the guide groove 240 match the guide rod 230, so that the guide rod 230 can be smoothly installed in the guide groove 240. The cooperation between the guide rod 230 and the guide groove 240 increases the stability of the mounting plate 210 of the clamp 400 on the one hand, preventing it from shaking or deflecting under the drive of the cylinder 200; on the other hand, it also provides a guiding effect for the movement of the mounting plate 210 of the clamp 400, ensuring that it can be lifted and lowered along a predetermined direction.

[0048] Reference Figures 3 to 5 In some embodiments of the present invention, the horizontal base 100 includes two connecting bed boards 110, and the two connecting bed boards 110 are connected in a detachable manner, which is convenient for assembly and disassembly, and is also convenient for storage and carrying.

[0049] The two connecting bed plates 110, as important components of the horizontal base 100, can be made of high-quality square steel pipes, which have sufficient strength and rigidity to withstand various loads of the tooling during operation. The two connecting bed plates 110 are connected in a detachable manner, such as bolt connection, snap connection, plug-in connection, etc. A cylinder 200 and a control valve 320 are arranged on each connecting bed plate 110. The cylinder 200 serves as a driving component and is responsible for providing the power required during the assembly process; and the control valve 320 is used to adjust the air pressure, stroke and other parameters of the cylinder 200 to meet the needs of different assembly processes.

[0050] In practical applications, the number and layout of the connecting plates 110, as well as the corresponding models and numbers of the cylinders 200 and the control valves 320, can be selected according to the shape, size and assembly process requirements of the workpiece. Then, the connecting plates 110 are assembled together by bolts or other connection methods, and the pipelines between the cylinders 200 and the control valves 320 are connected.

[0051] Reference Figure 5 and Figure 6 In some embodiments of the present invention, a set of efficient connection structures is designed, and a first plug-in block 120 and a second plug-in block 130 are respectively installed at the opposite ends of the two connecting bed boards 110. The first plug-in block 120 is designed as a component with two locating pins 121. Correspondingly, two pin holes 131 are provided on the second plug-in block 130, and the shapes and sizes of the two pin holes 131 match the locating pins 121 on the first plug-in block 120. The two locating pins 121 play a key positioning and guiding role, ensuring that the second plug-in block 130 can be accurately connected to the first plug-in block 120. The material of the locating pin 121 is selected from high-strength and wear-resistant materials to ensure stability and durability under long-term use. The locating pin 121 can adopt a variety of shapes such as cylindrical and polygonal.

[0052] In actual operation, the worker only needs to align the two connecting bed boards 110 and then gently push them so that the positioning pin 121 of the first plug-in block 120 can be smoothly inserted into the pin hole 131 of the second plug-in block 130. Due to the tight fit between the positioning pin 121 and the pin hole 131, a stable connection is formed between the two connecting bed boards 110 without the need for additional fixing devices or tools.

[0053] In addition, the above plug-in connection method also has the advantage of being easy to disassemble, such as Figure 5 As shown, after separation, the two connected bed boards 110 are stacked to reduce the occupied space and facilitate storage and carrying. The cylinder 200, the clamp 400, etc. can also be disassembled for easy carrying and transfer.

[0054] Reference Figure 6 Furthermore, the two connecting bed plates 110 are made of square steel pipes, and the air pipe between the switch valve 310 and the control valve 320 is hidden inside the square steel pipe. In order to meet the needs of rapid disassembly and assembly of the two connecting bed plates 110, a quick-connect male connector 340 is connected to the first plug-in block 120, and a quick-connect female connector 350 matching the quick-connect male connector 340 is connected to the second plug-in block 130. Through the rapid disassembly and assembly of the quick-connect male connector 340 and the quick-connect female connector 350, the disassembly and assembly requirements of the two connecting bed plates 110 are met. In terms of gas transmission, the quick-connect male connector 340 is connected to the switch valve 310 through the air pipe. The switch valve 310 is located on the connecting bed plate 110 where the first plug-in block 120 is located, and the quick-connect female connector 350 is connected to the air inlet pipe 321 to achieve gas path communication.

[0055] In actual operation, the assembler only needs to align the first plug block 120 and the second plug block 130, and then gently push to connect the quick-connect male connector 340 and the quick-connect female connector 350 at the same time, without the need for additional tools or equipment, thereby greatly improving assembly efficiency.

[0056] Reference Figure 5 and Figure 6 In some embodiments of the present invention, the interior of the connecting bed board 110 is designed with a through inner groove (such as the inner hole of a square steel pipe), and the first plug-in block 120 and the second plug-in block 130 are installed at the port of the inner groove. Since the quick-connect female head 350 and the quick-connect male head 340 are both in the inner groove, in order to operate the quick-connect female head 350, a movable groove connected to the inner groove is provided on the outer wall of the connecting bed board 110. The quick-connect female head 350 has a movable collar 351, which can move along the axis direction of the quick-connect female head 350. A push button 352 is provided on the movable collar 351, which passes through the movable groove and is exposed on the outside of the connecting bed board 110. The worker can control the movement of the movable collar 351 by operating the push button 352, thereby realizing the connection or disconnection between the quick-connect female head 350 and the plug-in block.

[0057] It is understandable that the connecting bed board 110 can be made of a material with an internal groove, such as a square steel pipe, or can be processed into an internal groove later, both of which can meet the use requirements and are not specifically limited.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
