Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a device for testing the flatness of an automotive dashboard crossbeam. Background Technology

[0002] Currently, the instrument panel crossbeam (CCB) is installed at the front of the driver's cab, hidden beneath the instrument panel, and is used to secure the instrument panel and its accessories. The CCB is mostly a metal structure that spans the left and right sides of the vehicle body, reinforcing the entire driver's cab. While the CCB has a simple structure, its shape is relatively complex, mainly consisting of a main beam, side supports, column supports, lower support legs, and auxiliary supports. Each of these components extends in a different direction and has mounting surfaces in various directions.

[0003] In production, the flatness requirements for the mounting surfaces of each component of the automotive dashboard crossbeam are high, so as to ensure that the dashboard crossbeam can be accurately installed in the cab and the dashboard can be accurately installed on the dashboard crossbeam. Therefore, the inspection of the flatness of the mounting surfaces of each component on the automotive dashboard crossbeam is particularly important.

[0004] In existing technologies, testing tools are generally used to inspect the flatness of each mounting surface of the components of the car dashboard crossbeam one by one. However, since there are many mounting surfaces on the car dashboard crossbeam, inspecting the flatness of each one is very time-consuming and inefficient. Moreover, the operation is too cumbersome for the staff and is also subject to human error. Utility Model Content

[0005] The purpose of this invention is to provide a flatness testing device for a car dashboard crossbeam, which aims to solve or at least partially solve the shortcomings of the aforementioned background technology. It can clamp and fix the entire car dashboard crossbeam and realize the flatness testing of the mounting surfaces of each part of the car dashboard crossbeam at one time. It is not only simple to operate and improves the testing efficiency, but also avoids human error in testing.

[0039] Please see Figure 1 and Figure 2 A device for detecting the flatness of a car dashboard crossbeam has a detection space 70 for accommodating the dashboard crossbeam and includes multiple detection units 100. The detection units 100 are used to detect the flatness of the dashboard crossbeam. The dashboard crossbeam includes a main beam, a left support, a right support, and a lower support leg. The left support and the right support are fixed to the left and right ends of the main beam, respectively, and the lower support leg is fixed to the main beam and extends downward and is located between the left support and the right support.

[0040] The vehicle dashboard beam flatness testing device also includes a worktable 60, a frame 50, a first drive mechanism 10, a second drive mechanism 20, two third drive mechanisms 30, and a controller.

[0041] The workbench 60 is equipped with a detection unit 100.

[0042] The frame 50 is fixed on the workbench 60. The frame 50 is equipped with a clamping mechanism 40, which is used to clamp and fix the instrument panel crossbeam to be tested. The frame 50 is equipped with a testing unit 100.

[0043] The first drive mechanism 10 is fixed on the frame 50, on which a detection unit 100 is provided and is used to drive the detection unit 100 to rotate to move closer to or away from the instrument panel crossbeam.

[0044] The second drive mechanism 20 is fixed on the worktable 60 and located below the first drive mechanism 10. It is equipped with a detection unit 100, which is used to drive the detection unit 100 to move up or down to get closer to or away from the instrument panel crossbeam.

[0045] Two third drive mechanisms 30 are respectively located at the left and right ends of the frame 50. The third drive mechanism 30 is equipped with a detection unit 100 and is used to drive the detection unit 100 to move up or down to get closer to or away from the instrument panel crossbeam.

[0046] The controller (not shown) is used to control the first drive mechanism 10, the second drive mechanism 20, the third drive mechanism 30 and multiple detection units 100 to work together and transmit the detection data of the detection units 100 to the computer. The computer analyzes the detection data to determine whether the flatness of each mounting surface is qualified.

[0047] Multiple detection units 100 are arranged around the detection space 70 by being mounted on the workbench 60, the frame 50, the first drive mechanism 10, the second drive mechanism 20, and the third drive mechanism 30.

[0048] As described above, the present invention provides a vehicle dashboard crossbeam flatness testing device. By providing a clamping mechanism 40, it can clamp and fix the entire vehicle dashboard crossbeam. Through the cooperation of the testing unit 100, worktable 60, frame 50, first drive mechanism 10, second drive mechanism 20, and third drive mechanism 30, multiple testing units 100 are arranged in a circular pattern around the testing space 70, allowing multiple testing units 100 to simultaneously perform flatness testing on the mounting surfaces of various parts of the vehicle dashboard crossbeam. Furthermore, through the cooperation of the controller, first drive mechanism 10, second drive mechanism 20, and third drive mechanism 30, in the initial state, the testing units 100 on the first drive mechanism 10, second drive mechanism 20, and third drive mechanism 30 are driven away from the testing space 70, facilitating the clamping and fixing of the dashboard crossbeam in the vehicle dashboard crossbeam flatness testing device. During testing, the first drive mechanism 10, second drive mechanism 20, and third drive mechanism 30 respectively drive the testing units 100 closer to the dashboard crossbeam and perform flatness testing. Therefore, the vehicle dashboard crossbeam flatness detection device provided by this utility model is not only simple to operate and improves detection efficiency, but also avoids human detection errors.

[0049] Please see Figure 6 The detection unit 100 includes a first driving device 101 and a detection probe 102 disposed at the movable end of the first driving device 101. The first driving device 101 drives the detection probe 102 to move closer to or away from the mounting surface of the instrument panel crossbeam. The detection unit 100 also includes a mounting base 103. The first driving device 101 is fixed on the mounting base 103, and the detection probe 102 is movably disposed on the mounting base 103. During operation, the first driving device 101 pushes the detection probe 102 to slide on the mounting base 103, and the detection probe 102 gradually moves closer to the mounting surface of the instrument panel crossbeam. In this embodiment, the first driving device 101 is a cylinder.

[0050] For more details, please see Figures 7-10 In a detection unit 100, one or more detection probes 102 may be used simultaneously. The end of the detection probe 102 may be needle-shaped, block-shaped, strip-shaped, column-shaped, etc., and the shape of the end of the detection probe 102 may be determined according to the specific shape of different mounting surfaces of the vehicle dashboard.

[0051] Please see Figure 11 and Figure 12The detection unit 100 on the first drive mechanism 10 is used to detect the flatness of the mounting surface on the front surface of the main beam of the instrument panel crossbeam.

[0052] The first drive mechanism 10 includes a second drive device 11, a fixed base 14, and a tilting plate 13. The second drive device 11 is fixed to the upper surface of the frame 50, and its movable end is connected to the fixed base 14 through a multi-link structure 12. One end of the tilting plate 13 is connected to the fixed base 14, and the other end of the tilting plate 13 is hinged to the frame 50 to form a static rotation fulcrum 511. A detection unit 100 is installed on the side of the fixed base 14 away from the second drive device 11. In this embodiment, the second drive device 11 is a cylinder.

[0053] More specifically, the frame 50 is provided with a hinge seat 51 that is hinged to the flip plate 13.

[0054] In the initial state, the movable end of the second drive device 11 is in a naturally extended state, and the flip plate 13 abuts against the upper surface of the hinge seat 51. When flipping, the movable end of the second drive device 11 retracts and pulls the fixed seat 14 around the static rotation fulcrum 511 upward through the multi-link structure 12, so as to drive the detection unit 100 on it away from the detection space 70. During detection, the movable end of the second drive device 11 extends and pushes the fixed seat 14 around the static rotation fulcrum 511 downward through the multi-link structure 12, so as to drive the detection unit 100 on it to approach the mounting surface on the front surface of the main beam of the instrument panel crossbeam.

[0055] More specifically, the multi-link structure 12 includes a first link 121 fixedly connected to the movable end of the second drive device 11, a second link 122 fixedly connected to the fixed seat 14, and a transmission rod 123 with its two ends hinged to the first link 121 and the second link 122, respectively. The two ends of the transmission rod 123 form a first hinge point 15 and a second hinge point 16 with the first link 121 and the second link 122, respectively. The first hinge point 15 and the second hinge point 16 can share the stress with the static rotation fulcrum 511 to distribute the stress and prevent wear or deformation at the static rotation fulcrum 511, thereby improving its reliability and preventing the tilting plate 13 and the fixed seat 14 from shifting during the tilting motion. At the same time, the swing of the transmission rod 123 can prevent the movement trajectory of the movable end of the second drive device 11 from interfering with the tilting trajectory of the tilting plate 13, avoiding dead points, so as to drive the tilting plate 13 and the fixed seat 14 to tilt.

[0056] Please see Figure 1The second drive mechanism 20 includes a first lifting unit 21, a second lifting unit 22, and a third lifting unit 23. Each of the first lifting unit 21, second lifting unit 22, and third lifting unit 23 is equipped with a detection unit 100, which is used to drive the detection unit 100 on it to move closer to or further away from the instrument panel crossbeam. The detection units 100 on the first lifting unit 21 and third lifting unit 23 are used to detect the flatness of the mounting surface on the front surface of the main beam of the instrument panel crossbeam, while the detection unit 100 on the second lifting unit 22 is used to detect the flatness of the mounting surface on the lower support leg of the instrument panel crossbeam.

[0057] Please see Figure 13 The first lifting unit 21 includes a third drive device 211, a first fixed frame 212, a first lifting seat 213, and a lateral sliding assembly 214. The third drive device 211 and the first fixed frame 212 are respectively fixed on the worktable 60. The first lifting seat 213 is slidably mounted on the first fixed frame 212 at an angle upwards. The third drive device 211 is located below the first lifting seat 213 and is used to drive the first lifting seat 213 to slide obliquely back and forth to approach or move away from the instrument panel crossbeam. More specifically, the first lifting seat 213 and the first fixed frame 212 are slidably connected by a slide rail structure 200. In this embodiment, the third drive device 211 is a cylinder.

[0058] The first lifting unit 213 is equipped with a lateral sliding assembly 214 and a detection unit 100. The lateral sliding assembly 214 also houses the detection unit 100. The lateral sliding assembly 214 drives the detection unit 100 to move laterally to a predetermined detection position. The first lifting unit 21 integrates the tilting and lifting and left-right horizontal sliding operations of the detection unit 100, avoiding the need for two separate drive mechanisms. This simplifies the number of components and reduces the size of the automotive dashboard crossbeam flatness detection device. Furthermore, the lateral sliding assembly 214 also prevents interference with the operation of the second drive mechanism 20.

[0059] More specifically, the lateral sliding assembly 214 includes a fourth drive device 2141 and a fixed platform 2142. The fourth drive device 2141 and the fixed platform 2142 are respectively fixed on the first lifting seat 213 and are laterally distributed. A detection unit 100 is slidably mounted on the fixed platform 2142. The detection unit 100 is slidably connected to the fixed platform 2142 through a slide rail structure 200, and the sliding direction of the detection unit 100 is parallel to the extension direction of the main beam of the instrument panel crossbeam. The fourth drive device 2141 is used to drive the detection unit 100 to slide laterally. In this embodiment, the fourth drive device 2141 is a cylinder.

[0060] In the initial state, the movable ends of the third drive device 211 and the fourth drive device 2141 are both in the retracted state. The first lifting seat 213 is located at the lowest position of the slide rail structure 200 of the first fixed frame 212, and the detection unit 100 slidably mounted on the fixed platform 2142 is close to the right side of the fixed platform 2142. During detection, the movable end of the third drive device 211 extends upward at an angle, and the third drive device 211 drives the first lifting seat 213 to extend upward at an angle close to the instrument panel crossbeam so that the detection unit 100 on it is close to the mounting surface on the front surface of the main beam of the instrument panel crossbeam. After the first lifting seat 213 slides into place, the movable end of the fourth drive device 2141 extends to drive the detection unit 100 on the fixed platform 2142 to slide to the left side of the fixed platform 2142 to the predetermined position.

[0061] Please see Figure 4 The second lifting unit 22 includes a seventh drive device 221, a third fixed frame 222, and a third lifting seat 223. The third fixed frame 222 is fixed on the worktable 60, the seventh drive device 221 is fixed to the lower part of the third fixed frame 222, and the third lifting seat 223 is slidably mounted upwards on the side wall of the third fixed frame 222. The seventh drive device 221 is located below the third lifting seat 223 and is used to drive the third lifting seat 223 to slide obliquely back and forth to approach or move away from the instrument panel crossbeam. More specifically, the third lifting seat 223 and the third fixed frame 222 are slidably connected by a slide rail structure 200. In this embodiment, the seventh drive device 221 is a cylinder.

[0062] In the initial state, the movable end of the seventh drive device 221 is in the retracted state, and the third lifting seat 223 is located at the lowest position of the slide rail structure 200 of the third fixed frame 222. During detection, the movable end of the seventh drive device 221 extends upward at an angle, and the seventh drive device 221 drives the third lifting seat 223 to tilt upward and approach the instrument panel crossbeam so that the detection unit 100 on it approaches the mounting surface on the lower support foot of the instrument panel crossbeam.

[0063] Please see Figure 3 The third lifting unit 23 includes an eighth drive device 231, a fourth fixed frame 232, and a fourth lifting seat 233. The fourth fixed frame 232 and the eighth drive device 231 are respectively fixed on the worktable 60. The fourth lifting seat 233 is vertically slidably mounted on the side wall of the fourth fixed frame 232. The eighth drive device 231 is located below the fourth lifting seat 233 and is used to drive the fourth lifting seat 233 to slide vertically back and forth to approach or move away from the instrument panel crossbeam. More specifically, the fourth lifting seat 233 and the fourth fixed frame 232 are slidably connected by a slide rail structure 200. In this embodiment, the eighth drive device 231 is a cylinder.

[0064] In the initial state, the movable end of the eighth drive device 231 is in the retracted state, and the fourth lifting seat 233 is located at the lowest position of the slide rail structure 200 of the fourth fixed frame 232. During detection, the movable end of the eighth drive device 231 extends vertically upward, and the eighth drive device 231 drives the fourth lifting seat 233 to move vertically upward toward the instrument panel crossbeam so that the detection unit 100 on it is close to the mounting surface on the front surface of the main beam of the instrument panel crossbeam.

[0065] Please see Figure 5 The third drive mechanism 30 includes a fourth lifting unit 31, which includes a fifth drive device 311, a second fixed frame 312, and a second lifting seat 313. The second fixed frame 312 is fixed on the workbench 60, and the second lifting seat 313 is slidably mounted vertically on the side wall of the second fixed frame 312 and is provided with a detection unit 100. The fifth drive device 311 is mounted on the frame 50 and its movable end is fixedly connected to the second fixed frame 312 through a connector 314. The fifth drive device 311 is located on one side of the second lifting seat 313 and is used to drive the second lifting seat 313 to slide vertically back and forth to approach or move away from the instrument panel crossbeam.

[0066] The aforementioned arrangement of the fifth drive device 311 and the second lifting seat 313 saves vertical space in the third drive mechanism 30, making its layout more compact and preventing interference between the third drive mechanism 30 and other mechanisms.

[0067] More specifically, the second lifting seat 313 and the second fixed frame 312 are slidably connected by a slide rail structure 200, and the connecting member 314 is L-shaped. In this embodiment, the fifth driving device 311 is a cylinder.

[0068] In the initial state, the movable end of the fifth drive device 311 is in the extended state, and the second lifting seat 313 is located at the lowest position of the slide rail structure 200 of the second fixed frame 312. During detection, the movable end of the fifth drive device 311 retracts vertically upward, and the fifth drive device 311 drives the second lifting seat 313 to move vertically upward toward the instrument panel crossbeam so that the detection unit 100 on it is close to the mounting surface on the left or right bracket of the instrument panel crossbeam.

[0069] Please see Figure 1 and Figure 14 The clamping mechanism 40 includes a manual clamping unit 41 and an automatic clamping unit 42. The manual clamping unit 41 and the automatic clamping unit 42 are arranged vertically and cooperate to clamp and fix the instrument panel crossbeam to be tested. The manual clamping unit 41 is a redundant design. When the automatic clamping unit 42 fails due to malfunction, power failure, or program error, the manual clamping unit 41 can serve as an emergency backup to ensure the continuity and safety of the testing production.

[0070] More specifically, the manual clamping unit 41 includes two operating handles 411, two first clamping arms 412, and two first positioning pins 413.

[0072] Please see Figure 2 The frame 50 is equipped with multiple detection units 100, which are used to detect the flatness of the lower support legs and the upper surface of the main beam of the instrument panel crossbeam. The worktable 60 is also equipped with multiple detection units 100, which are used to detect the flatness of the rear surface of the main beam of the instrument panel crossbeam. Therefore, by arranging the multiple detection units 100 around the detection space 70 on the worktable 60, frame 50, first drive mechanism 10, second drive mechanism 20, and third drive mechanism 30, the flatness of all mounting surfaces on the instrument panel crossbeam can be detected.

[0073] The working process of the automotive dashboard crossbeam flatness detection device provided in this embodiment is as follows:

[0074] (1) Initial stage: The movable end of the second drive device 11 is in a naturally extended state, the flip plate 13 abuts against the upper surface of the frame 50, and the detection unit 100 on the fixed seat 14 is close to the detection space 70; the movable ends of the third drive device 211 and the fourth drive device 2141 are both in a retracted state, so the detection unit 100 on the first lifting seat 213 is away from the detection space 70, and the detection unit 100 on the fixed table 2142 is close to the right side of the fixed table 2142; the movable end of the fifth drive device 311 is in a naturally extended state, so the detection unit 100 on the second lifting seat 313 is away from the detection space 70; the movable end of the seventh drive device 221 is in a retracted state, so the detection unit 100 on the third lifting seat 223 is away from the detection space 70; the movable end of the eighth drive device 231 is in a retracted state, so the detection unit 100 on the fourth lifting seat 233 is away from the detection space 70.

[0075] (2) Preparation stage: Start the second drive device 11. The movable end of the second drive device 11 retracts and pulls the fixed seat 14 around the static rotation fulcrum 511 upward through the multi-link structure 12, so as to drive the detection unit 100 on it away from the detection space 70, thereby making it convenient for the staff to clamp and fix the instrument panel beam in the vehicle instrument panel beam flatness detection device; then, the staff clamps and fixes the instrument panel beam through the clamping mechanism 40.

[0076] (3) Working stage: The movable end of the second drive device 11 extends and pushes the fixed seat 14 to rotate downward around the static rotation fulcrum 511 through the multi-link structure 12, so as to drive the detection unit 100 on it to approach the mounting surface on the front surface of the main beam of the instrument panel crossbeam; the movable end of the third drive device 211 extends to drive the first lifting seat 213 to tilt upward and approach the instrument panel crossbeam so that the detection unit 100 on it approaches the mounting surface on the front surface of the main beam of the instrument panel crossbeam. After the first lifting seat 213 slides into place, the movable end of the fourth drive device 2141 extends to drive the detection unit 100 on the fixed platform 2142 to the left of the fixed platform 2142. The instrument slides to a predetermined position; the movable end of the fifth drive unit 311 retracts to drive the second lifting seat 313 vertically upward to approach the instrument panel crossbeam, so that the detection unit 100 on it approaches the mounting surface on the left or right bracket of the instrument panel crossbeam; the movable end of the seventh drive unit 221 extends to drive the third lifting seat 223 tilting upward to approach the instrument panel crossbeam, so that the detection unit 100 on it approaches the mounting surface on the lower support foot of the instrument panel crossbeam; the movable end of the eighth drive unit 231 extends to drive the fourth lifting seat 233 vertically upward to approach the instrument panel crossbeam, so that the detection unit 100 on it approaches the mounting surface on the front surface of the main beam of the instrument panel crossbeam.

[0077] (4) Detection stage: After all the detection units 100 on the first drive mechanism 10, the second drive mechanism 20 and the third drive mechanism 30 reach the predetermined position, all the detection units 100 on the vehicle instrument panel crossbeam flatness detection device start to work. The first drive device 101 pushes the detection probe 102 to slide on the mounting base 103. The detection probe 102 abuts against each mounting surface on the instrument panel crossbeam to detect its flatness. The controller receives the detection data and transmits it to the computer for result analysis.

[0078] (5) Recovery phase: After the test is completed, the second drive mechanism 20 drives the test unit 100 on it to return to the position of the preparation phase. The second drive mechanism 20 and the third drive mechanism 30 respectively drive the test unit 100 on them to return to the position of the initial phase. The staff can take out the instrument panel beam. Then, the second drive mechanism 20 drives the test unit 100 on it to return to the position of the initial phase.
