Description

Technical Field

[0001] The utility model relates to a flexible adapter for vehicle measurement, in particular to a flexible adapter for vehicle optical measurement. Background Art

[0002] In the fields of automobile manufacturing and quality control, constructing a vehicle coordinate system and performing accurate vehicle dimension measurement are crucial steps. As Figure 5a shown, the RPS (Reference Point System) holes are located on the longitudinal beams at the bottom of the vehicle. Traditional measurement methods have to rely on a lift or a traveling crane to safely lift the vehicle to ensure that the measurement equipment can reach and accurately read the data of these key reference points. Therefore, mainstream automobile manufacturers at home and abroad generally choose to use vehicle measurement brackets or flexible vehicle measurement brackets as support tools to conduct detailed inspections and analyses on each component of the vehicle body.

[0003] As Figure 5b shown, the current vehicle measurement technology adopts a combined design of an air-floating substrate 23, a column support plate 24, columns 25 and different column heads 26. The air-floating substrate technology utilizes the principle of the air-floating module technology. By injecting high-pressure gas into the air-floating substrate 23, the substrate can be suspended under the action of gas buoyancy. This technology can significantly reduce mechanical friction and improve the operation accuracy and stability of the equipment. The air-floating substrate 23 is usually processed from imported high-precision and high-strength plates, and double-sided matrix holes are machined on the surface to achieve better gas distribution and suspension effect. The column support plate 24 and the columns are key components connecting the air-floating substrate 23 and different column heads 26. The column support plate 24 usually adopts a high-precision matrix hole plate design and fits tightly with the air-floating substrate 23 to ensure the stability of the entire measurement system. The columns 25 are made of high-strength and high-precision materials and can support different column heads 26 and withstand various loads during the measurement process. The column head 26 is the end-executing component of the vehicle measurement bracket. Different types of column heads 26 can be designed according to different measurement requirements. It can be adjusted according to different heights and workpiece requirements to meet the measurement requirements of different workpieces. Integrating the air-floating substrate 23, the column support plate 24, the columns 25 and the column heads 26 into a whole system, through precise control systems and sensor technologies, high-precision and high-efficiency measurement of the vehicle can be achieved. The entire system adopts a digital and intelligent design concept, can real-time feedback measurement data, and conduct data analysis and processing through a software system.

[0004] However, this traditional whole-vehicle measurement method has exposed several significant limitations in practical applications: First, it is highly dependent on a set of complex hardware facilities, including customized whole-vehicle measurement brackets, whole-vehicle lifting devices and fixed measurement platforms, which not only increases investment costs, but also forces companies to plan and manage a large number of measurement sites and storage spaces; second, since the measurement process must be carried out on a specific platform, this greatly limits the flexibility and efficiency of the measurement. Usually, it takes 3 to 5 days to complete the comprehensive measurement and analysis of a whole vehicle, and only a single vehicle can be operated in the same time period, which is difficult to meet the rapid response requirements of large-scale production lines; third, the layout of the three-coordinate measurement points in the whole-vehicle coordinate system is often sparse, and may not fully cover all key dimensional information, affecting the detailedness and accuracy of the measurement results; finally, the column head connected to the RPS hole is complex in design, and an additional redundant clamping structure needs to be configured to ensure a stable clamping effect, which not only increases the cumbersomeness of the operation, but also may introduce additional error factors due to the complexity of the clamping structure. Utility Model Content

[0005] The purpose of the utility model is to provide a flexible adapter for whole vehicle optical measurement that can be directly inserted into the RPS hole of the whole vehicle without a clamping structure for whole vehicle measurement on the ground. The adapter uses a strong magnetic sinking structure of the Z-direction reference surface, which is adsorbed on the RPS hole by magnetic force, so that the vehicle can identify the RPS hole of the whole vehicle when it is stationary, thereby establishing a whole vehicle coordinate system. The adapter realizes rapid installation, positioning and measurement between different vehicle models, solves the problem that the whole vehicle cannot be measured on the ground using the whole vehicle coordinate system and the pain points of current traditional whole vehicle measurement.

[0006] The utility model provides a flexible adapter for optical measurement of a whole vehicle, comprising: a base column, a flexible probe, a support and an optical recognition component. The base column is formed by connecting a longitudinal part and a transverse part to form a T-shaped structure. The flexible probe comprises a positioning surface, a magnetic component and a positioning pin, the magnetic component is installed in the positioning surface, the positioning pin is installed on the upper part of the positioning surface, and the lower part of the positioning surface is connected to the longitudinal profile. The measurement of different vehicle models can be achieved by simply replacing probes with different diameters. The flexible adapter for optical measurement of the whole vehicle can achieve rapid installation, positioning and measurement between vehicle models through the flexible probe. The support is installed on the base column. The optical recognition component is installed on the support.

[0007] The longitudinal profile has an internal thread, and the lower part of the positioning surface has an external thread, and the two are connected together by threading.

[0008] The positioning pin is inserted into the RPS hole, and the magnetic component is used to provide magnetic force to be adsorbed on the RPS hole.

[0009] The magnetic component is made into a sinking structure, so that the high-precision reference surface fits the Z-direction surface of the RPS hole of the vehicle body, which enables the vehicle to identify the RPS hole of the whole vehicle when it is stationary, thereby establishing the coordinate system of the whole vehicle. This avoids redundant clamping structures, ensures measurement accuracy, and makes operation very convenient.

[0010] The diameter of the positioning pin has three specifications, namely 20mm, 25mm and 30mm.

[0011] The support is mounted on the base column by bolts.

[0012] An iron sheet is arranged in the circular hole at the center of the support, and a magnetic mounting component is adsorbed on the iron sheet.

[0013] The optical recognition component is adsorbed on the support through a magnetic mounting component.

[0014] The optical recognition component comprises an optical reference ball seat and an optical reference ball. The optical reference ball seat is provided with a spherical groove matching the optical reference ball, and the optical reference ball is directly embedded in the spherical groove.

[0015] The optical recognition component includes an optical recognition base and an optical recognition point, and the optical recognition point is fixed on the optical recognition base by gluing.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model of the flexible adapter for whole vehicle optical measurement eliminates the limitation of the measuring platform and realizes the measurement of the whole vehicle in a stationary state, which effectively reduces the measurement cost and improves the measurement efficiency.

[0018] 2. The main structure of the utility model vehicle optical measurement flexible adapter is compatible with optical shooting scanning and laser scanning equipment. The adapter uses optical recognition technology to accurately identify the RPS hole, effectively solving the problem of insufficient three-coordinate vehicle measurement points in the vehicle coordinate system, thereby improving the comprehensiveness and accuracy of the measurement data.

[0019] 3. The utility model of the flexible adapter for optical measurement of the whole vehicle abandons the reliance on a lift or crane in traditional measurement. It can directly and conveniently complete the comprehensive measurement of the whole vehicle on the ground only by relying on its flexible handheld data recognition base column main structure, which significantly improves the flexibility and operability of the measurement.

[0020] 4. The utility model vehicle optical measurement flexible adapter adopts a magnetic reference surface structure and a flexible probe structure, and can measure different vehicle models without the need for redundant clamping structures.

[0021] 5. The utility model provides a flexible adapter for whole vehicle optical measurement, and the base column is light in weight, so it is convenient for a single person to operate it barehandedly.

[0050] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0051] Figure 1 and Figure 2 The structure diagram and front view of the flexible adapter for optical measurement of a vehicle according to the preferred embodiment of the utility model are respectively. The structure of the flexible adapter for optical measurement of a vehicle according to the preferred embodiment of the utility model comprises: a base column 11, a flexible side head 12, a support 13 and an optical recognition component 14. Preferably: Figure 1 and Figure 2 As shown, the base column 11 is connected by a longitudinal portion 111 and a transverse portion 112, the bottom of the longitudinal portion 111 is connected to the middle position of the transverse portion 112, and the longitudinal portion 111 and the transverse portion 112 are connected together by bolts to form a holding structure, which is a T-shaped structure. The design of the T-shaped structure allows multiple functional components to be compactly integrated on a base column, reducing the number of parts, simplifying the complexity of the system, and thus reducing the overall cost. This integrated design also promotes assembly efficiency during the production process. This lightweight design greatly improves the convenience of operation and facilitates single-person barehanded operation. This not only reduces the work intensity of the operator, but also improves work efficiency and safety. It is worth noting that the holding structure of the base column 11 is not limited to Figure 1 and Figure 2 The T-shaped structure shown, the holding structure can also be a cross-shaped structure or any other structure that can meet the requirements of integrated components and optical measurement.

[0052] The material of the longitudinal portion 111 and the transverse portion 112 of this embodiment is a profile, and more preferably, an aluminum profile. The aluminum profile has the characteristic of low density, which greatly reduces the overall weight of the base column. At the same time, the aluminum profile has high strength, which ensures the accuracy and stability of the measurement. In addition, the material selection of the longitudinal portion 111 and the transverse portion 112 is not limited to aluminum profiles. They can also be made of materials such as stainless steel, titanium alloy and engineering plastics to meet the comprehensive requirements of strength, lightness and specific application environment requirements.

[0053] like Figure 1 and Figure 2 As shown, the base column 11 and the flexible probe 12 are connected together. The flexible probe 12 is connected to the top of the longitudinal part of the T-shaped structure of the base column, and the two are connected by threads. The flexible probe 12 includes a positioning pin 121, a magnetic component 122 and a positioning surface 123, the magnetic component 122 is installed in the positioning surface 123, the positioning pin 121 is installed on the upper part of the positioning surface 123, and the lower part of the positioning surface 123 is connected to the longitudinal part 111. Preferably, the magnetic component 122 is reserved with a shape matching the groove of the positioning surface 123, and is installed inside the positioning surface 123 by precise embedding. In order to ensure a stable connection between the magnetic component 122 and the positioning surface 123, a high-strength adhesive is used to fill the small gap between the groove and the magnetic component 122, and a tight bonding layer is formed after curing. The positioning pin 121 is installed on the upper part of the positioning surface 123 by threaded connection. The bottom of the positioning pin 121 is designed with a threaded hole matching the positioning surface 123, and the positioning surface 123 is provided with a corresponding mounting hole. During the installation process, the threaded portion of the positioning pin 121 is first aligned with the mounting hole on the positioning surface 123, and then the positioning pin 121 is screwed into the mounting hole using a special threaded tightening tool until a predetermined tightening torque is reached. The lower part of the positioning surface 123 and the longitudinal part 111 are connected by threads, the longitudinal part 111 has an internal thread, and the lower part of the positioning surface 123 has an external thread, and the two are tightly connected by threads. This combination combines the advantages of embedded installation and threaded connection, which not only ensures the stable connection between the magnetic component 122 and the positioning surface 123, but also facilitates the precise alignment of the flexible probe 12 by adjusting the positioning pin 121. At the same time, the use of high-strength adhesives further enhances the reliability and durability of the connection, ensuring that the flexible probe 12 can maintain stable performance in a complex and changeable measurement environment.

[0054] like Figure 1 and Figure 2As shown, during measurement, the positioning pin 121 is inserted into the RPS hole, and the magnetic component 122 is used to provide magnetic force to adsorb on the RPS hole. The magnetic component 122 has a sinking structure so that the high-precision reference surface fits the Z-direction surface of the RPS hole of the vehicle body. This allows the vehicle to identify the RPS hole of the entire vehicle when it is stationary, thereby establishing a vehicle coordinate system. The flexible adapter for optical measurement of the entire vehicle realizes rapid installation, positioning and measurement between vehicle models through the flexible probe 12.

[0055] like Figure 3 As shown, the number of the adapter adsorption holes 27 of the flexible adapter for optical measurement of a whole vehicle of the present invention is three.

[0056] like Figure 1 As shown, the support 13 is mounted on the base column 11. Preferably, the support 3 is mounted on the base column 11 by bolts. It should be understood that the support 13 is not limited to being mounted on the base column 11 by bolts. The support 13 can also be connected to the base 11 by welding or the like. There is an iron sheet 15 in the circular hole at the center of the support 13, and a magnetic mounting component 16 is adsorbed on the iron sheet 15.

[0057] like Figure 1 As shown, the optical recognition component 14 is mounted on the support 13, and preferably, the optical recognition component 14 is adsorbed on the support 13 through a magnetic mounting component 16. The optical recognition component 14 includes an optical reference ball seat 141 and an optical reference ball 142, and the optical reference ball seat 141 has a spherical groove matching the optical reference ball 142, and the optical reference ball 142 is directly embedded therein.

[0058] The optical recognition component 14 is mounted on the support 13. Preferably, the optical recognition component 14 is adsorbed on the support 13 via a magnetic mounting component 16. The optical recognition component 14 includes an optical recognition base and an optical recognition point, and the optical recognition point is fixed on the optical recognition base by gluing.

[0059] The utility model discloses a flexible adapter for whole vehicle optical measurement, which integrates optical identification points or optical reference balls on a base column, thereby achieving the effects of cost reduction, simple operation and space saving.

[0060] Preferably, in this embodiment, the diameter of the positioning pin 121 is 20 mm.

[0061] Preferably, in this embodiment, the diameter of the positioning pin 121 is 25 mm.

[0062] Preferably, in this embodiment, the diameter of the positioning pin 121 is 30 mm.

[0063] Preferably, in this embodiment, the weight of the vehicle optical measurement flexible adapter is 1.4 kg.

[0064] The use process of the flexible adapter for optical measurement of the whole vehicle of the utility model is as follows: before starting the optical measurement process of the whole vehicle, careful preparation is required to ensure the accuracy and reliability of the measurement results. First, a suitable measurement environment is selected, which must be flat and vibration-free, with stable light and avoid direct sunlight to reduce the potential impact of external factors on the measurement accuracy. At the same time, clean the surrounding area of ​​the vehicle to be measured to ensure that the measuring equipment and the operator have sufficient operating space. Subsequently, the equipment is checked. The flexible adapter for optical measurement of the whole vehicle and its components (including the base column 11, the flexible probe 12, the support 13 and the optical recognition component 14) are in good condition, without wear, corrosion or loose connection. In addition, confirm that the optical measurement equipment (such as laser trackers, high-precision optical cameras, etc.) has been professionally calibrated, the battery is sufficient, and the supporting software is the latest version to ensure the accuracy of the measurement data. In terms of vehicle preparation, the vehicle to be measured needs to be parked in the designated measurement area, ensure that the four wheels of the vehicle are on the same horizontal plane, turn off all movable parts, and remove dirt and obstructions on the surface of the vehicle so that the optical recognition module can clearly capture the characteristic points on the surface of the vehicle.

[0065] The installation process of the flexible adapter for whole-vehicle optical measurement must be accurate. The operator needs to hold the assembled adapter, accurately align the locating pin 121 of the flexible probe 12 with the RPS hole on the vehicle, and insert it into the hole stably. At this time, the adapter is firmly adsorbed on the RPS hole through the magnetic component 122. After the installation is completed, a stability check is required to confirm whether the adapter is firmly fixed by gently shaking it. If there is any looseness, the position of the locating pin 121 should be adjusted immediately or the magnetic strength of the magnetic component 122 should be checked, and a stronger magnetic component should be replaced if necessary. Next, the optical recognition module 14 is accurately installed on the support 13 to ensure that the mounting surface is flat and free of foreign matter, and the connection between the optical recognition module 14 and the support 13 is tight and reliable. After the installation is completed, preliminary debugging is required to ensure that it can accurately identify the feature points on the vehicle surface.

[0066] like Figure 4a and Figure 4b As shown, after the whole vehicle optical measurement flexible adapter of the utility model is installed, it is firmly adsorbed on the Z-direction plane of the main control RPS at the bottom of the whole vehicle in a vertical posture, ensuring its precise positioning and firm connection in three-dimensional space. This design not only optimizes the contact area between the adapter and the bottom structure of the vehicle and enhances the firmness of adsorption, but also enables the adapter to accurately capture and transmit the measurement data in the Z direction (i.e., the vertical direction), providing a more accurate and reliable reference for whole vehicle measurement. At the same time, the vertical adsorption form also helps to reduce the measurement error caused by the tilt or offset of the adapter, further improving the accuracy and efficiency of whole vehicle measurement.

[0067] When all preparations are completed, the optical measurement equipment can be started to perform a preliminary scan on the optical recognition module 14 to check its working state and recognition effect. During the scanning process, the equipment needs to be kept stable to ensure the continuity and accuracy of the data. At the same time, it is necessary to pay close attention to the real-time changes in the measurement data and adjust the equipment parameters in time to deal with possible abnormal situations. According to the scanning results, a whole vehicle coordinate system is established in the measurement software, and key feature points are selected as the benchmark. The origin, direction and scale of the coordinate system are determined by calculating the relative position relationship between them. In the process of establishing the coordinate system, the stability and consistency of the coordinate system need to be maintained to avoid measurement errors caused by changes in the coordinate system. After the measurement is completed, the collected data needs to be deeply analyzed and processed. Using the measurement software to process and analyze the data, key information such as the geometric parameters and form and position tolerances of the vehicle can be extracted, and the manufacturing quality and assembly accuracy of the vehicle can be evaluated accordingly. In order to ensure the accuracy of the data, multiple scans and calibrations are required to ensure the accuracy and stability of the coordinate system. The use of this adapter makes it very simple and efficient to establish the coordinate measurement of the whole vehicle. There is no need to lift the vehicle, equip the measuring platform, or equip the flexible bracket and air-floating plate. This greatly reduces the measurement site and storage site, and greatly reduces the measurement cost. The problem of few three-coordinate whole vehicle measurement points in the whole vehicle coordinate system can be perfectly solved by using the whole vehicle optical measurement adapter, making the measurement data more comprehensive and the data more widely used and efficient. In addition, the whole vehicle measurement does not need to be restricted by the measuring platform. The adapter is only used in the coordinate establishment stage and can be unplugged at any time after the coordinates are established. Through simple plug-in and unplug operations, multiple vehicles can be analyzed at the same time, which greatly improves work efficiency.

[0068] The above-mentioned embodiments are only further explanations of the utility model, and are not intended to limit the utility model in other forms. The utility model may also have other various embodiments. Without departing from the spirit and essence of the utility model, those skilled in the art may make various corresponding modifications and changes according to the utility model, but these corresponding modifications and changes shall fall within the protection scope of the utility model.
