Description

Technical Field

[0001] This utility model relates to the field of positioning devices, and provides a vehicle body assembly positioning device. Background Technology

[0002] The assembly process for rail vehicle bodies typically involves aligning the centerlines of component connections for positioning and assembly. This method is simple and direct, suitable for scenarios with small component deviations. However, in actual production, the machining accuracy of large components cannot be fully guaranteed, often resulting in problems such as diagonal deviations.

[0003] When a large component of the vehicle body, such as the chassis, has a significant diagonal deviation, the installation of subsequent components will be affected. For example, after the sidewalls are installed, the chassis deviation will cause the sidewalls on both sides of the vehicle body to deviate along the length of the vehicle. The accumulation of this error will eventually lead to a large overall diagonal deviation of the vehicle body.

[0004] Excessive diagonal deviation of the vehicle body will significantly impact the installation accuracy of interior components, affecting vehicle comfort and safety. Therefore, there is an urgent need for a method to effectively prevent error accumulation and control the overall diagonal deviation of the vehicle body. Utility Model Content

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] like Figure 1 As shown, this utility model embodiment provides a vehicle body assembly positioning device, including:

[0029] Support column 100 is used to support the vehicle body assembly platform 102;

[0030] A level instrument, installed on the ground, is used to adjust the level of the support surface of the support column 100;

[0031] Laser 104 is installed on the ground and set along the longitudinal centerline, transverse centerline and height centerline of the vehicle assembly platform 102. The longitudinal centerline, transverse centerline and height centerline form a reference plane.

[0032] The center positioning block is set at a position corresponding to the lateral center, longitudinal center, and height center of the vehicle body. The center positioning block is used to achieve positioning with the laser 104.

[0033] According to the vehicle body assembly positioning device provided in this embodiment, the position of the vehicle body can be determined very accurately through the cooperation of the laser 104 and the central positioning block, greatly reducing errors in the assembly process. Because the positioning process is more intuitive and faster, the assembly time of the vehicle body can be significantly shortened, improving production efficiency. Precise positioning helps ensure that the various components of the vehicle body can accurately align and cooperate during assembly, thereby improving the overall quality and stability of the vehicle body. The device is designed with a certain degree of flexibility, and can be adjusted and adapted according to different vehicle models and sizes to meet diverse assembly needs. Furthermore, this vehicle body assembly positioning device can also be applied to various application scenarios such as the driver's cab, side walls, end walls, and roof.

[0034] Please continue reading Figure 1 This utility model aims to provide a vehicle body assembly positioning device to ensure that the vehicle body can be accurately aligned and positioned during the assembly process, thereby improving assembly efficiency and quality. The device mainly consists of the following key components.

[0035] The support columns 100 are used to stably support the vehicle assembly platform 102, ensuring the stability and load-bearing capacity of the platform throughout the assembly process. The number and layout of the support columns 100 are rationally designed according to the size and weight of the vehicle body.

[0036] The level is installed on the ground and is in contact with or close to the support surface of the support column 100. Its main function is to adjust and confirm whether the support surface of the support column 100 is level, thereby ensuring that the vehicle assembly platform 102 is on a level surface and avoiding assembly errors caused by uneven ground.

[0037] Lasers 104 are also mounted on the ground, but their position and orientation are carefully designed. Specifically, lasers 104 are positioned along the longitudinal centerline, transverse centerline, and height centerline of the vehicle assembly platform 102. These three lines together form a reference plane, providing a precise reference for vehicle assembly. The use of lasers 104 makes the positioning process more intuitive and accurate.

[0038] For example, when the underframe, sidewalls, and roof are installed sequentially along the length of the vehicle, they can be positioned using the same reference line formed by the laser, and then adjusted according to this reference line. This positioning adjustment refers to the fact that, for example, the line connecting the center points of the upper and lower parts of the sidewall may not be collinear with the laser marking line. The installation position of the sidewall needs to be adjusted based on the offset of the upper and lower parts to ensure that the final installation position is optimal for the overall vehicle body.

[0039] The center positioning blocks are set on the vehicle body, corresponding to the vehicle body's lateral center, longitudinal center, and height center. Their main function is to receive and respond to the beam of light from the laser 104. When the center positioning blocks are aligned with the beam of light emitted by the laser 104, it means that the vehicle body has been accurately positioned on the reference plane.

[0040] According to one embodiment of the present invention, the support column 100 is provided with adjustable foot pads.

[0041] And / or,

[0042] The support column 100 includes a lifting column and a support surface. The lifting column is located on the ground, and the support surface is located at the end of the lifting column that is away from the ground.

[0043] In one specific embodiment of this utility model, the design of the support column 100 has been further optimized to improve its adaptability and stability.

[0044] Adjustable feet are added to the bottom of the support column 100. These feet are typically made of wear-resistant, non-slip materials and are equipped with adjustment mechanisms, such as threaded rods, knobs, or hydraulic devices, allowing the operator to make fine adjustments according to uneven ground conditions. By adjusting the height of the feet, the verticality and stability of the support column 100 can be ensured, maintaining the level of the vehicle assembly platform 102 even on uneven ground.

[0045] The support column 100 is designed as a combination of a lifting column and a support surface. The lifting column is located on the ground and its height is adjusted by means of a motor, pneumatic, or hydraulic drive. The support surface is located at the end of the lifting column that is away from the ground and is used to directly support the vehicle assembly platform 102. This design not only provides a wider range of height adjustment but also allows the platform height to be adjusted according to actual needs, facilitating assembly operations for the operator.

[0046] The combination of adjustable foot pads and rising columns with the support surface allows the support column 100 to cope with various uneven ground conditions, ensuring the stability and levelness of the vehicle assembly platform 102. This helps reduce errors during assembly and improve product quality. By adjusting the height of the foot pads and rising columns, the verticality and stability of the support column 100 can be ensured, preventing swaying or tilting caused by uneven ground or vibrations during operation. This helps ensure operator safety while improving the accuracy of assembly operations. The introduction of rising columns allows for flexible height adjustment of the support column 100, meeting the height requirements of different vehicle models and assembly needs. This flexibility helps improve production line utilization and efficiency. Adjustable foot pads and rising columns are typically equipped with easy-to-operate adjustment mechanisms, allowing operators to quickly and accurately adjust the height and stability of the support column 100. This helps simplify the assembly process and improve production efficiency.

[0047] According to one embodiment of the present invention, the central positioning block is provided with a measurement interface for docking with external measuring tools.

[0048] In one specific embodiment of this invention, the design of the central positioning block has been further optimized by adding a measurement interface for docking with external measuring tools. This design aims to improve the measurement accuracy and efficiency during the vehicle assembly process.

[0049] Specifically, the measurement interface on the center positioning block can be a standardized interface, such as a threaded hole, slot, or magnetic adsorption surface, to facilitate docking with external measuring tools (such as laser rangefinders, vernier calipers, micrometers, etc.). These measuring tools are tightly connected to the center positioning block through the interface, enabling precise measurement of the vehicle body assembly position.

[0050] The design of the measurement interface takes into full consideration both ease of operation and measurement accuracy. The position, size, and shape of the interface have been carefully calculated and optimized to ensure a perfect match with external measuring tools. At the same time, the interface surface is treated with wear-resistant and corrosion-resistant materials to improve service life and measurement accuracy.

[0051] By interfacing with external measuring tools through the measurement interface on the central positioning block, precise measurements of the vehicle assembly position can be achieved, reducing measurement errors and improving product quality. The introduction of the measurement interface simplifies the measurement process, reduces the tediousness and time-consuming nature of manual measurements, and improves assembly efficiency. The standardized measurement interface design makes the central positioning block compatible with various external measuring tools, improving the equipment's versatility and flexibility. The tight connection between the measurement interface and external measuring tools prevents slippage or detachment during measurement, ensuring operator safety.

[0052] According to one embodiment of the present invention, a connecting component is provided between the support column 100 and the level instrument to enable rapid adjustment and calibration of the support column 100.

[0053] In one specific embodiment of this utility model, an innovative connecting component is provided between the support column 100 and the level instrument. This device is designed to enable rapid adjustment and calibration of the support column 100, thereby improving the flexibility and accuracy of the vehicle assembly positioning device.

[0054] The design of the connection assembly fully considers the stability and ease of adjustment of the connection between the support column 100 and the level. Specifically, the connection assembly includes one or more adjustment mechanisms, such as rotary adjusters, sliding rails, or telescopic rods, which allow the operator to quickly adjust the height and angle of the support column 100 as needed. Simultaneously, the connection assembly is also equipped with calibration mechanisms, such as a bubble level, fine-tuning knobs, or an electronic calibration system, to ensure that the support column 100 remains level after adjustment.

[0055] In addition, the connecting components may include locking mechanisms, such as locking screws, snaps, or magnetic adsorption devices, to fix the position of the support column 100 after adjustment, preventing it from moving or tilting during use.

[0056] The design of the connecting components allows for quick and accurate adjustment of the height and angle of the support column 100, reducing adjustment time and labor costs during assembly. Equipped with a calibration mechanism, the connecting components ensure that the support column 100 remains level after adjustment, thus improving the accuracy of the vehicle assembly positioning device. The locking mechanism securely fixes the support column 100 in the desired position after adjustment, preventing wobbling or tilting due to uneven ground or vibrations during operation, thus improving the stability of the entire device. The connecting components are designed with flexibility, allowing for adjustment and adaptation to different vehicle models and assembly requirements, meeting diverse assembly needs.

[0057] According to one embodiment of the present invention, the laser 104 is a green laser 104.

[0058] In one specific embodiment of this invention, the laser 104 is a green laser 104. This choice is primarily based on the unique characteristics and advantages of green lasers, as well as their potential value in vehicle assembly and positioning applications.

[0059] The laser beam generated by the green laser 104 has a bright green color, which is highly sensitive to the human eye, making the laser beam more visually striking and easily identifiable. Furthermore, the green laser 104 typically exhibits good beam quality, with high coherence and monochromaticity, ensuring the stability and accuracy of the laser beam during transmission.

[0060] In the vehicle body assembly positioning device, green lasers 104 are positioned along the longitudinal centerline, transverse centerline, and height centerline of the vehicle body assembly platform 102. These laser beams form a precise reference plane, providing a visual reference for vehicle body assembly. The operator can quickly and accurately determine whether the vehicle body is in the correct position by observing the alignment of the laser beams with the center positioning block.

[0061] The green laser 104 generates a high-brightness and high-accuracy laser beam, ensuring precise positioning of the vehicle body during assembly. This helps reduce assembly errors and improve product quality. The green laser beam is also more visually conspicuous, making it easier for operators to observe the alignment of the laser beam with the center positioning block. This contributes to improved assembly efficiency and reduced operational difficulty. Although the laser beam generated by the green laser 104 is bright, it generally does not cause permanent damage to the human eye (within a reasonable power range). This allows operators to maintain a high level of comfort when using the laser 104 for extended periods, reducing safety hazards caused by glare or discomfort from the laser beam. The green laser 104 is not only suitable for vehicle body assembly positioning but can also be widely applied in other applications requiring high-precision positioning, such as machining, precision measurement, and automated production lines. This further expands the applicability and potential market value of this invention.

[0062] According to one embodiment of the present invention, the support column 100 is a steel support column 100.

[0063] In one specific embodiment of this utility model, the support column 100 is made of high-strength aluminum alloy. As a lightweight and high-strength metal material, aluminum alloy has good corrosion resistance and easy processing, making it very suitable for manufacturing structural components that need to withstand certain loads while also requiring lightweight construction.

[0064] Steel possesses extremely high strength and durability, capable of withstanding significant loads and long-term stress without easily deforming or damaging, thus ensuring the stability and reliability of the support column 100. With appropriate treatment (such as galvanizing and painting), the steel support column 100 effectively resists environmental corrosion, extending its service life, especially performing exceptionally well in humid or corrosive environments. Steel is easy to shape and cut, facilitating the customization of the support column 100's shape and size to specific needs, enhancing design flexibility and adaptability.

[0065] According to one embodiment of the present invention, the central positioning block is a magnetic central positioning block.

[0066] In one specific embodiment of this invention, a magnetic center positioning block is used as the center positioning block. This design is primarily based on the unique advantages of magnetic positioning technology and its potential value in vehicle assembly positioning applications.

[0067] The core of the magnetic center positioning block lies in its internal strongly magnetic material, which generates a powerful magnetic field, allowing the positioning block to firmly adhere to the vehicle body or other magnetic surfaces. Simultaneously, the magnetic center positioning block also possesses a magnetic center—the area where the magnetic field is most concentrated and powerful—which enables the positioning block to provide greater adhesion and a more stable positioning effect when adhering to objects.

[0068] In the vehicle body assembly positioning device, a magnetic center positioning block is precisely set at the center of the assembly platform, serving as a reference point during the vehicle body assembly process. Operators can quickly and accurately determine whether the vehicle body is in the correct position by observing the magnetic positioning block's adhesion to the vehicle body or other magnetic components. Furthermore, the magnetic center positioning block can be used in conjunction with external measuring tools (such as laser rangefinders and vernier calipers) to achieve precise measurement and adjustment of the vehicle body assembly position.

[0069] The magnetic center positioning block utilizes the principle of magnetic fields for positioning, offering high accuracy and stability. It ensures the precise positioning of the vehicle body during assembly, reducing assembly errors and improving product quality. The strong magnetic material inside the magnetic center positioning block generates a powerful magnetic field, providing sufficient adsorption force so that the positioning block can firmly adhere to the vehicle body or other magnetic surfaces, preventing it from easily falling off or moving. Magnetic positioning technology requires no complex mechanical structures or external power sources; positioning is achieved solely through the interaction of magnetic fields. This simplifies and speeds up the operation, reducing operational difficulty and costs. The magnetic center positioning block is applicable to vehicle body parts of different materials and shapes, requiring only that the parts possess a certain degree of magnetism or magnetizability. This gives this invention a wider range of applications in the field of vehicle body assembly positioning. By adopting the magnetic center positioning block, positioning time during vehicle body assembly can be significantly shortened, improving production efficiency. Furthermore, due to its accurate and stable positioning, it can reduce rework and repair costs caused by inaccurate positioning.

[0070] It should be noted that the magnetic center positioning block is used for carbon steel vehicle bodies. When the vehicle body is made of aluminum alloy or stainless steel, a magnetic fixing block can be set at the corresponding position inside the vehicle body and used in conjunction with the magnetic center positioning block.

[0071] According to one embodiment of the present invention, a control component is also included, which is electrically connected to the support column 100.

[0072] In one specific embodiment of this utility model, in addition to the basic support structure and positioning device, a control component is added. This control component is electrically connected to the support column 100, thereby forming a complete control system.

[0073] The core function of the control component is to intelligently control and manage the entire vehicle assembly positioning device. It can precisely control actions such as the raising and lowering of the support column 100, the movement of the positioning block, and the data acquisition of sensors based on preset parameters and instructions. Simultaneously, the control component can also receive signals from external devices, such as manual input from the operator and linkage signals from other automated equipment, to achieve a more flexible and intelligent control method.

[0074] Specifically, the control component includes one or more microprocessors, control circuits, communication interfaces, and other key components. The microprocessor, acting as the brain of the control component, is responsible for processing various input signals and instructions, and making decisions and outputting control signals based on preset algorithms and logic. The control circuit is responsible for converting the microprocessor's output signals into actual control actions, such as driving motors, solenoid valves, and other actuators. The communication interface is used to enable data exchange and communication between the control component and external devices.

[0075] By introducing control components, intelligent control and management of the entire vehicle body assembly and positioning device are achieved. This significantly improves the automation level of the device and reduces manual intervention and operational complexity. The control components can precisely control the device according to preset parameters and instructions, ensuring that actions such as the lifting of the support column 100 and the movement of the positioning blocks meet predetermined accuracy requirements. This helps improve the accuracy and stability of vehicle body assembly. Automated control can significantly shorten the vehicle body assembly cycle and improve production efficiency. At the same time, due to the intelligent management and optimization functions of the control components, production costs and energy consumption can be further reduced. The control components can perform real-time monitoring and fault diagnosis of the entire device, promptly identifying and addressing potential safety hazards. This helps improve the safety and reliability of the entire vehicle body assembly and positioning device. The control components typically adopt a modular design, facilitating later maintenance and upgrades. When it is necessary to update functions or repair faults, only the corresponding modules need to be replaced or upgraded, without requiring large-scale modifications to the entire device.

[0076] According to one embodiment of the present invention, it further includes a mounting base 106, which is disposed on the ground, and a laser 104 is disposed on the mounting base 106.

[0077] In one specific embodiment of this utility model, in addition to the support column 100, positioning block, and control components mentioned above, a mounting base 106 is also provided. This mounting base 106 is stably set on the ground, and its main function is to serve as a support and mounting platform for the laser 104.

[0078] The design of the mounting base 106 fully considers the usage requirements and ease of installation of the laser 104. It is made of high-strength, corrosion-resistant materials to ensure sufficient stability and durability during use. At the same time, the structural design of the mounting base 106 has also been carefully considered to ensure that the laser 104 can be accurately mounted on it and maintain a stable emission angle and position.

[0079] Mounting base 106 is typically provided with mounting holes or mounting slots that match the laser 104, so as to securely fix the laser 104 thereon. In addition, in order to ensure that the laser 104 can maintain a horizontal or specific tilt angle when emitting a laser beam, mounting base 106 is also equipped with a fine adjustment mechanism, such as a fine adjustment knob or adjusting bolt.

[0080] Mounting base 106 serves as a support platform for laser 104, ensuring sufficient stability during use. This helps reduce positional shifts of laser 104 caused by uneven ground or vibrations, thereby improving the emission accuracy and stability of the laser beam. The design of mounting base 106 simplifies and facilitates the installation and adjustment of laser 104. The operator simply places laser 104 on mounting base 106 and makes necessary adjustments using the fine-tuning mechanism to achieve precise laser beam emission. The design of mounting base 106 offers flexibility, accommodating different models and specifications of laser 104. This means that this invention can easily adapt to different vehicle assembly requirements without requiring major modifications to mounting base 106. The addition of mounting base 106 further enhances the overall performance of the vehicle assembly positioning device. It enables laser 104 to emit laser beams more stably and accurately, providing a more reliable reference for vehicle assembly. Mounting base 106 also protects laser 104. It can isolate the laser 104 from direct contact with the ground, preventing it from being damaged by ground abrasion, corrosion or impact.

[0081] According to one embodiment of the present invention, the height of the mounting base 106 is adjustable.

[0082] In one specific embodiment of this utility model, the mounting base 106 is designed to be height-adjustable. This design is mainly to meet the different height requirements of the laser 104 in different vehicle body assembly and positioning needs. By adjusting the height of the mounting base 106, it can be ensured that the laser beam emitted by the laser 104 can be accurately projected onto the predetermined position on the vehicle body assembly platform 102, thereby improving the accuracy and efficiency of positioning.

[0083] To achieve height adjustment of the mounting base 106, various technical means can be employed. For example, a height adjustment mechanism, such as a screw lifting mechanism, hydraulic lifting mechanism, or pneumatic lifting mechanism, can be installed at the bottom of the mounting base 106. These mechanisms can be adjusted manually or electrically to achieve precise control of the height of the mounting base 106.

[0084] In addition, to ensure the stability of the mounting base 106 after height adjustment, auxiliary structures such as support feet, fixing bolts, or locking mechanisms can be incorporated into the design. These structures can securely fix the mounting base 106 to the ground after it is adjusted to the required height, preventing positional displacement due to vibration or external forces.

[0085] By adjusting the height of the mounting base 106, the laser beam emitted by the laser 104 can be precisely projected onto the predetermined position on the vehicle assembly platform 102. This helps improve the positioning accuracy of vehicle assembly, reducing errors and rework rates. The height-adjustable mounting base 106 makes this invention applicable to vehicle assembly platforms 102 of different heights and sizes. This enhances its practicality and flexibility, enabling its wider application in various vehicle assembly scenarios. Since the height of the mounting base 106 can be easily adjusted, operators do not need to frequently move or rearrange the laser 104 to adapt to different assembly requirements. This saves significant time and effort, improving work efficiency. Adjusting the height of the mounting base 106 also avoids direct contact between the laser 104 and the ground or other objects, reducing the risk of damage. This helps extend the lifespan of the laser 104 and reduce maintenance costs. The height-adjustable mounting base 106 makes it easier for operators to install and adjust the laser 104. This not only improves work convenience but also enhances overall user satisfaction and experience.
