Description

Technical Field

[0001] This utility model relates to the field of strength testing technology, and more specifically, to a strength testing device for the inner plate of column A. Background Technology

[0002] In the automotive body structure, the A-pillar is located at the front of the vehicle, connecting the roof and both sides of the windshield. The A-pillar inner panel is an important component of the A-pillar structure, its main function being to enhance the strength and rigidity of the A-pillar, while also absorbing energy and protecting occupants in a collision. During the production process of the A-pillar inner panel, strength testing is required, including applying pressure to the inner panel to test its load-bearing capacity. For example, patent application number 202321136006.2 proposes a strength testing device for automotive door inner panel production, including a base plate, a base fixedly connected to the top of the base plate, a motor mounted on the outside of a support plate, a screw fixedly connected to the outside of the motor, a rubber pad mounted on the outside of a clamping plate, a connecting rod slidably connected to the outside of the clamping plate, a top plate fixedly connected to the top of the support rod, a telescopic cylinder mounted on the top of the top plate, a sliding plate mounted on the outside of the telescopic cylinder, two symmetrically distributed lead screw slide rails mounted on the bottom of the sliding plate, a pressure plate mounted on the outside of the lead screw slide rails, and a pressure sensor mounted on the bottom of the pressure plate. This automotive door inner panel production strength testing device can test multiple door inner panels at once and display the pressure during testing, making it convenient for users to understand. At the same time, the screw and slide rail setting also makes it convenient for users to adjust the position of the pressure plate, thus facilitating the testing of door inner panels of different sizes.

[0003] The strength testing device in the above scheme requires the inner panel to be unfixed and then manually adjusted when testing different positions of the same inner panel. The operation process is cumbersome, time-consuming, and reduces work efficiency. Therefore, we have made an improvement and proposed a strength testing device for the inner panel of column A.

A top plate 5 is installed on the top of the support plates 4. A hydraulic cylinder 6 is installed in the middle of the upper surface of the top plate 5. A pressure plate 7 is installed at the output end of the hydraulic cylinder 6 and below the top plate 5. A pressure sensor 8 is installed on the lower surface of the pressure plate 7. A display 11 is installed on one side surface of one of the support plates 4. The display 11 is electrically connected to the pressure sensor 8. Second cylinders 9 are installed on both sides of the upper surface of the top plate 5. The output end of each second cylinder 9 passes through the top plate 5 and a limit plate 10 is installed at the end.

[0024] like Figure 3 , Figure 4 , Figure 5 As shown, the position adjustment mechanism 3 includes a support frame 301, which is fixedly installed on the lower surface of the workbench 1. A first cylinder 302 is installed at the bottom of the support frame 301, and an installation plate 303 is installed at the output end of the first cylinder 302. The installation plate 303 is located inside the through groove 2. Limiting rods 3031 are installed on both sides of the lower surface of the installation plate 303, and the two limiting rods 3031 are inserted into the bottom of the support frame 301. A groove 304 is formed on the upper surface of the installation plate 303, and a first mounting groove 305 is formed on the inner walls of both sides of the groove 304. A first drive motor 306 is installed inside one of the first mounting grooves 305, and a first adjusting screw 307 is installed at the output end of the first drive motor 306. One end of the first adjusting screw 307 is rotatably installed on the inner wall of one end of the first mounting groove 305 at the corresponding position. A first adjusting screw 307 is movably installed on the shaft of the first adjusting screw 307. A lead screw sleeve 308 has a connecting plate 309 mounted on one end surface. One end of the connecting plate 309 is slidably disposed inside a first mounting groove 305 on the side away from the first adjusting lead screw 307. A guide slider 3091 is mounted in the middle of the lower surface of the connecting plate 309. A limiting groove 3041 that slides with the guide slider 3091 is provided on the bottom inner wall of the groove 304. A second mounting groove 310 is provided on the upper surface of the connecting plate 309. A second drive motor 311 is mounted on one side inside the second mounting groove 310. A second adjusting lead screw 312 is mounted on the output end of the second drive motor 311. One end of the second adjusting lead screw 312 is rotatably disposed on the inner wall of one end of the second mounting groove 310. A second lead screw sleeve 313 is movably mounted on the rod of the second adjusting lead screw 312. A top block 314 is mounted on the top of the second lead screw sleeve 313. An anti-slip pad 315 is provided on the upper surface of the top block 314.

[0025] The first cylinder 302 controls the top block 314 to lift the inner plate, which in turn drives the first drive motor 306 and the second drive motor 311 to adjust the position of the lifted inner plate. The sliding cooperation between the guide slider 3091 and the limiting groove 3041 limits the movement trajectory of the connecting plate 309, making it more stable during movement. The top block 314 is provided with an anti-slip pad 315, which makes the inner plate more stable and less prone to slipping during the lifting process, facilitating position adjustment.

[0026] The working principle of the inner plate strength testing device for column A:

[0027] In use, the inner plate to be tested for strength is placed on the surface of the workbench 1. The second cylinder 9 pushes the limiting plate 10 down to fix the position of the inner plate. Then, the hydraulic cylinder 6 controls the pressure plate 7 to press down on the inner plate. When the pressure plate 7 is pressed down to the limit position, it will continue to press down to squeeze the inner plate, thereby enabling the strength test. The pressure sensor 8 on the lower surface of the pressure plate 7 can monitor the pressure generated during the squeezing in real time, and the value is displayed on the display 11, which makes it more convenient for the staff to observe. When different positions need to be inspected, the pressure plate 7 and the limiting plate 10 are first moved upwards. Then, the mounting plate 303 is pushed upwards by the first cylinder 302, so that the top block 314 contacts the lower surface of the inner plate and lifts the inner plate, making it separate from the upper surface of the worktable 1. Then, driven by the first drive motor 306 and the second drive motor 311, the top block 314 can be moved under the meshing action between the first adjusting screw 307, the second adjusting screw 312 and the first screw sleeve 308 and the second screw sleeve 313, so that the inner plate can be adjusted in front and behind and left and right. Different positions of the same inner plate can be moved to the bottom of the pressure plate 7, so that different positions can be inspected. There is no need to manually adjust the position of the inner plate, making the operation simpler, less time-consuming, and effectively improving work efficiency.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
