Description

Technical Field

[0001] This invention belongs to the field of anti-roll torsion bar and bogie assembly, specifically relating to an anti-roll torsion bar auxiliary assembly device and assembly method. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] The assembly of the anti-roll torsion bar in the bogie frame crossbeam is a crucial step in ensuring stable vehicle operation. As a large and heavy component, the anti-roll torsion bar is 2250mm long and approximately 160mm high. Therefore, when the anti-roll torsion bar is inserted into the bogie frame crossbeam for assembly, it is prone to tipping and tilting due to instability of the center of gravity. This not only affects the accuracy and quality of assembly but also increases the safety risks of operation.

[0004] Existing assembly methods often require multiple people to work together, resulting in high labor costs and low efficiency. More importantly, the high precision requirements of the torsion bar shaft surface, especially the spline surface which must be free of any damage, place extremely high demands on the operational skills and safety precautions during the assembly process. In addition, the long stroke of the anti-roll torsion bar in the inner hole of the bogie frame crossbeam further increases the difficulty of assembly; to ensure that the installation positions on both sides of the bogie frame are approximately the same after assembly, precise control and adjustment of the assembly process are required. Summary of the Invention

[0005] To address these issues and improve assembly efficiency and precision, this invention proposes an anti-roll torsion bar auxiliary assembly device and assembly method.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present invention provides an auxiliary assembly device for an anti-roll torsion bar, comprising a support frame, an end clamping device at one end of the top of the support frame, and an auxiliary support device at the other end; the end clamping device is movable along the length direction of the support frame; a limiting device is provided between the auxiliary support device and the end clamping device, the limiting device comprising a limiting pin, a pull wire, and a rotating handle; the rotating handle is mounted on the top of the support frame via a connecting shaft, and the rotating handle is rotatably connected to the connecting shaft; one end of the rotating handle is connected to one end of the limiting pin via a pull wire; the other end of the limiting pin cooperates with the auxiliary support device, and a return spring is provided on the limiting pin.

[0008] As a further technical solution, the auxiliary support device includes a support rod, a support roller is provided at the top of the support rod, and a limit groove is provided on the side of the support rod.

[0009] As a further technical solution, the end clamping device includes a slide plate, on which a U-shaped seat is provided, and on the top of the U-shaped seat is an anti-roll torsion bar end clamping mechanism.

[0010] As a further technical solution, two anti-roll torsion bar end clamping mechanisms are provided, each set on the top of the U-shaped seat.

[0011] As a further technical solution, each anti-roll torsion bar end clamping mechanism includes a rotating rod, a support seat, and a support bearing. The rotating rod passes through the support seat and the support bearing. A rotating handle is fixed at one end of the rotating rod, and a clamping claw is installed at the other end. By rotating the rotating handle, the clamping claw can cooperate with the end of the anti-roll torsion bar, thereby achieving the clamping of the end of the anti-roll torsion bar.

[0012] As a further technical solution, the contact surface between the clamping claw and the fixed end of the anti-roll torsion bar is a rubber layer.

[0013] As a further technical solution, a locking pin is also included, wherein the locking pin locking end clamping device is used.

[0014] As a further technical solution, the support frame is a lifting frame.

[0015] As a further technical solution, the anti-roll torsion bar auxiliary assembly device also includes a mobile vehicle, and the anti-roll torsion bar auxiliary assembly device is installed on the mobile vehicle.

[0016] Secondly, the present invention also provides a method for assembling an anti-roll torsion bar using the aforementioned anti-roll torsion bar auxiliary assembly device, as follows:

[0017] Step 1. Move the auxiliary assembly device to the position for installing the anti-roll torsion bar using a mobile cart;

[0018] Step 2. Clamp the end of the anti-roll torsion bar using the end clamping device, and use the auxiliary support device to support the anti-roll torsion bar;

[0019] Step 3. After fixing the anti-roll torsion bar, push the anti-roll torsion bar auxiliary assembly device to the side of the bogie frame;

[0020] Step 4. Install the guide sleeve on the front end of the anti-roll torsion bar; adjust the position of the anti-roll torsion bar auxiliary assembly device so that the torsion bar is aligned with the bogie frame mounting hole; push the moving vehicle to install the front half of the anti-roll torsion bar into the bogie frame mounting hole;

[0021] Step 5. Release the end clamping device; push the end clamping device. As the end clamping device is pushed forward, it touches the limit device. The limit device controls the auxiliary support device to fall. Then the end clamping device continues to move forward until the anti-roll torsion bar is fully assembled into the bogie frame.

[0022] Step 6. Remove the guide sleeve and assemble the torsion bar mounting bracket on the other side; assembly complete.

[0023] The beneficial effects of the above embodiments of the present invention are as follows:

[0024] The anti-roll torsion bar auxiliary assembly device proposed in this invention can achieve stable fixation and anti-detachment of the anti-roll torsion bar. Specifically, the anti-roll torsion bar is fixed by an end clamping device, and an auxiliary support device provides auxiliary support to prevent it from falling off. Since the auxiliary support device can affect the forward movement of the end clamping device during the pushing of the anti-roll torsion bar into the bogie frame, this invention designs a limiting device. The end clamping device touches the limiting device, causing the limiting pin of the limiting device to lose its restraint on the auxiliary support device, allowing the auxiliary support device to fall. The end clamping device continues to move forward until the anti-roll torsion bar is fully inserted into the bogie frame. During the insertion of the anti-roll torsion bar into the inner hole of the frame crossbeam, this invention achieves precise control of the torsion bar's movement. This control method effectively prevents potential bumps during insertion, thus avoiding surface damage and reduced precision. This not only ensures assembly quality but also extends the service life of the torsion bar. Furthermore, the end clamping device of this invention can achieve precise fastening and stopping of the anti-roll torsion bar; this end clamping device can not only ensure the stability of the torsion bar during the assembly process and prevent it from moving or tilting, but also effectively avoid safety accidents caused by loosening or falling off.

[0032] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] For ease of description, the words "up," "down," "left," and "right" appearing in this invention only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Terminology Explanation: The terms "installation," "connection," "linking," and "fixing" in this invention 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 connection of two components or the interaction relationship between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, the present invention proposes an anti-roll torsion bar auxiliary assembly device and assembly method.

[0037] In a typical embodiment of the present invention, such as Figure 1As shown, this embodiment discloses an anti-roll torsion bar auxiliary assembly device, including a support frame 7. An anti-roll torsion bar end clamping device is provided at one end of the top of the support frame 7, and an anti-roll torsion bar auxiliary support device is provided at the other end. The anti-roll torsion bar end clamping device can move along the length direction of the support frame 7. A limiting device is provided between the anti-roll torsion bar auxiliary support device and the anti-roll torsion bar end clamping device. The limiting device limits the anti-roll torsion bar auxiliary support device in the height direction. When the auxiliary support device is raised to a certain height, the limiting device limits the anti-roll torsion bar auxiliary support device to prevent it from falling suddenly.

[0038] When comparing the length of the anti-roll torsion bar, if the anti-roll torsion bar is moved and assembled solely by clamping it with an end clamping device, the stability is too poor. Therefore, in this embodiment, an auxiliary support device for the anti-roll torsion bar is added to the other end. However, since the anti-roll torsion bar needs to be fully assembled into the component, the setting of the auxiliary support device for the anti-roll torsion bar will inevitably affect the assembly of the anti-roll torsion bar. Therefore, this embodiment sets a limiting device. Through the cooperation of the end clamping device and the limiting device, when the end clamping device moves the anti-roll torsion bar to the position of the limiting device, the limiting device can control the support device to fall automatically, thereby making room for the movement of the end clamping device, so that the anti-roll torsion bar can be fully assembled into the component. When it is necessary to raise the support device, it can be raised manually.

[0039] Furthermore, a guide rail 8 is provided along the length of the top of the support frame 7, and the anti-roll torsion bar end clamping device can move along the guide rail 8. Specifically, the movement of the anti-roll torsion bar end clamping device can be achieved by manual pushing or by motor drive; the choice can be made according to actual needs. When the end clamping device is not moving, it is locked to the top of the support frame 7 by a locking pin to prevent it from moving. The reason why the anti-roll torsion bar end clamping device is set as a movable device in this embodiment is that when the anti-roll torsion bar is actually assembled, the end clamping device is needed to push the anti-roll torsion bar into the component. Therefore, the end clamping device must be designed as a movable structure.

[0040] Furthermore, the anti-roll torsion bar end clamping device includes a slide plate 6, which is slidably connected to the guide rail 8. A U-shaped seat 1 is provided on the slide plate 6, and an anti-roll torsion bar end clamping mechanism is provided on the top of the U-shaped seat 1. Two anti-roll torsion bar end clamping mechanisms are provided, respectively provided on the top of the U-shaped seat 1. Each anti-roll torsion bar end clamping mechanism includes a rotating rod 20 and a support seat 3. The rotating rod 20 passes through the support seat 3 and the support bearing located in the support seat 3. A rotating handle 4 is fixed at one end of the rotating rod 20, and a clamping claw 2 is installed at the other end. By rotating the rotating handle 4, the clamping claw 2 can cooperate with the end of the anti-roll torsion bar 18, thereby achieving the clamping of the end of the anti-roll torsion bar.

[0041] Furthermore, the clamping claw 2 fixes the end face of the anti-roll torsion bar by rotating the clamping handle, and the contact surface between the clamping claw 2 and the fixed end of the anti-roll torsion bar 18 is a rubber layer, ensuring that there is no damage to the surface of the anti-roll torsion bar 18 during clamping and that it is more secure.

[0042] The aforementioned anti-roll torsion bar auxiliary support device includes a support rod 14, with a support roller 13 at the top of the support rod 14, and a limiting groove 15 on the side of the support rod 14. The limiting groove 15 cooperates with the limiting pin 12 of the limiting device to achieve limiting. Furthermore, the support rod 14 can also be raised or lowered relative to the support frame 7. The raising or lowering of the support rod can be automatically controlled or manually controlled. When automatic control is used, a linear drive device is installed at its bottom to drive its raising and lowering.

[0043] Furthermore, the limiting device includes a limiting pin 12, a pull wire 10, a fixed seat 16, and a rotating handle 9. The rotating handle 9 is mounted on the top of the support frame 71 via a connecting shaft, and the rotating handle 9 is rotatably connected to the connecting shaft. The rotating handle 9 is fitted onto the rotating shaft, and under the action of external force, the rotating handle 9 can rotate relative to the connecting shaft. One end of the rotating handle 9 is connected to one end of a limiting pin 12 via the pull wire 10. The other end of the limiting pin 12 is engaged with the limiting groove of the support rod 14. A return spring 11 is provided on the limiting pin 12. One end of the return spring 11 abuts against the fixed seat 16, and the other end abuts against the protrusion on the limiting pin 12. The return spring 11 provides a certain pushing force to the limiting pin 12, so that when the external force applied to the rotating handle 9 is removed, the return spring 11 works, pushing the limiting pin 12 to move towards the support rod 14, thereby limiting the support rod 14 in the height direction.

[0044] The process of the limiting device cooperating with the aforementioned end clamping device is as follows:

[0045] When the end clamping device moves along the guide rail 8 to the position of the rotating handle 9, it will touch the rotating handle 9, causing the rotating handle 9 to rotate. The rotating handle 9 then pulls the pull line 10 towards the side where the end clamping device is located, and the pull line 10 pulls the limit pin 12, causing the limit pin 12 to disengage from the upper limit groove of the support rod 14. At this time, the support rod 14 will automatically fall down without affecting the end clamping device to continue moving forward, so that the end clamping device can continue to push the anti-roll torsion bar 18 forward until the anti-roll torsion bar 18 is installed in place.

[0046] After the anti-roll torsion bar is installed, when the end clamping device returns to its original position, the support rod 14 needs to be raised again for the installation of the next anti-roll torsion bar 18. At this time, first manually rotate the rotating handle 9 so that the limiting pin 12 does not affect the raising of the support rod 14, and then pull the support rod 14 upward. When the support rod 14 rises to the set height, release the rotating handle 9. At this time, the limiting pin 12 is inserted into the limiting groove of the support rod 14 under the action of the return spring 11, thereby limiting the support device.

[0047] Furthermore, the support frame 7 in this embodiment adopts an existing scissor lift device, which will not be described in detail here. Of course, it is easy to understand that the support frame 7 can also adopt other lifting forms, such as linear lifting devices driven by hydraulic cylinders or pneumatic cylinders, etc., which can be selected according to actual needs.

[0048] Furthermore, this embodiment also includes a control system. When the movement of the anti-roll torsion bar end clamping device on the guide rail and the lifting of the support frame 7 are automatically controlled, a control system needs to be added to control the corresponding motors, etc. When the movement of the anti-roll torsion bar end clamping device and the lifting of the support frame 7 are manually controlled, the control system may not be included.

[0049] Furthermore, in this embodiment, rollers 17 are installed at the bottom of the support frame 7, and a moving cart 9 is installed at one end of the support frame 7 to enable the movement of the entire device. Alternatively, the anti-roll torsion bar auxiliary assembly device can be directly placed on a moving cart 9 to enable its overall movement. The moving cart 9 and the scissor lift device adopt an advanced electric control system: the moving cart is an electric trolley, and the electric trolley and scissor lift device are equipped with an advanced electric control system, allowing operators to easily start, stop, lift, and report errors of the trolley using the control handle and control box. This control system is not only easy to operate but also responds quickly, providing a strong guarantee for efficient and safe assembly operations. At the same time, the introduction of the electric control system also improves the intelligence level of the equipment, further improving work efficiency and quality.

[0050] Furthermore, the assembly device in this embodiment adopts a flexible design, so it can be applied to the installation of anti-roll torsion bars for all vehicle models.

[0051] Meanwhile, the other end of the anti-roll torsion bar is supported by an auxiliary support roller to ensure that the anti-roll torsion bar remains horizontal during installation. After the anti-roll torsion bar is aligned with the mounting hole, the fixing fixture is pushed to move on the guide rail, and the support roller rolls until the anti-roll torsion bar is basically fully installed in the bogie frame. Then, the handle is turned to pull the cable to pull out the limit pin, the auxiliary support descends, and the clamping fixture is used to further push the anti-roll torsion bar to the installation limit.

[0052] This invention utilizes an electric trolley to achieve the alignment and handling of the anti-roll torsion bar across its four degrees of freedom (up, down, left, and right), thus enabling push-in assembly. The introduction of the electric trolley not only reduces manual handling and labor intensity but also ensures the stability and precision of the assembly process through a precise control system. Furthermore, the inclusion of anti-detachment tools further enhances the safety of the assembly process.

[0053] The anti-roll torsion bar auxiliary assembly device proposed in this embodiment can also effectively avoid impact damage: during the process of the anti-roll torsion bar being inserted into the inner hole of the frame beam, this invention achieves precise control of the torsion bar's movement through the auxiliary assembly device. This control method effectively prevents potential impacts torsion bars during insertion, thereby avoiding surface damage and reduced accuracy. This not only ensures assembly quality but also extends the service life of the torsion bar.

[0054] The anti-roll torsion bar auxiliary assembly device proposed in this embodiment enables efficient and safe lifting and transportation: Utilizing a mobile cart and support frame, this invention achieves convenient lifting and transportation of the anti-roll torsion bar. The mobile cart and support frame can be precisely operated via remote control and manual control buttons, allowing for accurate control of the lifting height. This lifting and transportation method not only significantly improves work efficiency but also requires only one person, greatly reducing the investment of human resources. Simultaneously, it avoids the safety risks that may arise from traditional overhead crane hoisting and the coordination problems that may occur with multiple people working together.

[0055] This invention is an auxiliary tooling for anti-roll torsion bars, which mainly relies on the coordinated action of components such as the vehicle body, lifting platform, auxiliary support and auxiliary support limiting device, and workpiece clamping support tooling. The following describes the usage process of this invention using automatic control as an example:

[0056] Step 1. Movement and Positioning: Move the auxiliary assembly device to the position for installing the anti-roll torsion bar using a moving vehicle.

[0057] Step 2. Clamping the anti-roll torsion bar: Place the anti-roll torsion bar mounting base (which has been pre-assembled on the anti-roll torsion bar) on the end clamping device of the auxiliary assembly device; rotate the rotating handle of the end clamping device to lock the anti-roll torsion bar through the clamping jaws, and use the auxiliary support device to support the anti-roll torsion bar.

[0058] Step 4. After fixing the anti-roll torsion bar, push the anti-roll torsion bar auxiliary assembly device to the side of the bogie frame;

[0059] Step 5. Initial assembly:

[0060] Install the guide sleeve at the front end of the anti-roll torsion bar to prevent damage to the inner wall of the pipe during assembly;

[0061] Adjust the position of the anti-roll torsion bar auxiliary assembly device so that the torsion bar is aligned with the bogie frame mounting hole;

[0062] The moving trolley is used to install the front half of the anti-roll torsion bar into the bogie frame mounting hole; that is, the front half of the anti-roll torsion bar is mainly installed into the bogie frame mounting hole with the help of the moving trolley; the role of the moving trolley is to move the entire device on the one hand, and to assist in the assembly of the anti-roll torsion bar on the other hand.

[0063] Step 6. Continue assembly:

[0064] Pull out the locking pin 5 on the back of the end clamping device;

[0065] The end clamping device is pushed forward and touches the limit device during the forward push. The limit device controls the auxiliary support device to fall down. Then the end clamping device continues to move forward until the anti-roll torsion bar is fully assembled into the bogie frame.

[0066] Remove the guide sleeve and assemble the torsion bar mounting bracket on the other side.

[0067] Step 7. End and Evacuation:

[0068] After assembly, the auxiliary tooling is moved to the parking location.

[0069] Throughout the process, the auxiliary support and auxiliary support limiting mechanism play a crucial supporting and limiting role, ensuring the stability and safety of the anti-roll torsion bar during assembly. Meanwhile, the support frame and the XY-direction sliding rails provide the necessary movement and adjustment space, allowing the tooling to flexibly adapt to different assembly requirements.

[0070] Through this design, the present invention achieves stable fixation, efficient handling, precise assembly, and avoidance of impact damage to the anti-roll torsion bar, thereby significantly improving the efficiency and safety of assembly operations.

[0071] Finally, it should be noted that relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
