Description

Technical Field

[0001] The present application relates to the technical field of door guard plate detection, and specifically to a vehicle door guard plate detection tool. Background Art

[0002] Car door panels are panels installed on car doors. They can withstand and cushion the impact when the car collides, thereby protecting the safety of people inside the car. When a car collides, there are many situations, such as collisions with larger impact forces and scratches with smaller impact forces. In the event of a collision with a larger impact force, there are higher requirements for the hardness and supporting protection capabilities of the car door panels, otherwise it will not be able to cushion the impact force and protect the safety of people inside the car; in the event of a collision with a smaller impact force, the car door panels are required to have a certain degree of elasticity and deformation ability to offset the impact force. Car panels that are too hard and cannot undergo slight deformation are prone to cracking when a collision with a small impact force occurs.

[0003] Therefore, door guard panels need to be strength tested before being put into use to detect whether the car door guard panels meet safety standards based on the deformation of the door guard panels.

[0004] The patent with publication number CN110487650A discloses a strength detection device for door guard panels. It is equipped with a bottom plate, a fixed column, a top plate, a hydraulic cylinder, an impact block, and a placement plate. The impact block is driven down by the hydraulic cylinder to impact the door guard panel, detect its strength, and judge whether the door guard panel is qualified based on the deformation ratio.

[0005] Although the above-mentioned device realizes the strength test of the door guard panel by pressing the impact head downward through the hydraulic cylinder, the single impact head can only detect a local area when punching the door guard panel, and multiple tests are required for other undetected areas, which is relatively time-consuming. In addition, the impact head only relies on point punching on the door guard panel, and the local strength may be acceptable, but it is difficult to simulate the denting of the door guard panel when it is subjected to large-scale collision, extrusion and other external forces. This makes the test results have certain limitations, which is not conducive to judging the standardization of the door guard panel quality. It is also difficult to accurately record and compare the quality of door guard panels of different batches. Therefore, it is necessary to provide an automobile door guard panel inspection tool to solve the above problems.

[0042] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0044] Example 1: Figure 1-Figure 3 As shown, the present application provides an automobile door guard plate inspection tool, comprising a frame 1, the frame 1 having a detection platform 102, and a controller 101 mounted on the frame 1, the controller 101 being used to control the operation of each driving component, and a fixing mechanism 2 being mounted on the frame 1, the fixing mechanism 2 being used to clamp the door guard plate;

[0045] The fixing mechanism 2 includes a storage box 201 fixedly mounted on the inspection table 102, the storage box 201 is used to place the door guard plate, and a mounting platform 202 is fixedly mounted on both side end surfaces of the storage box 201, the mounting platform 202 is used to support the door guard plate, and a plurality of sets of pressing devices 203 are fixedly mounted on the mounting platform 202, the pressing devices 203 are used to press the door guard plate onto the mounting platform 202;

[0046] Two sets of first cylinders 204 are fixedly mounted on both sides of the storage box 201. The telescopic ends of the first cylinders 204 are movable through the storage box 201. Clamps 205 are fixedly mounted on the telescopic ends of the first cylinders 204. The clamps 205 are adapted to move linearly with the telescopic ends of the first cylinders 204 to clamp both sides of the door guard plate.

[0047] like Figure 1-Figure 2 As shown, an impact mechanism 3 is mounted on the testing platform 102. The impact mechanism 3 includes four sets of pillars 301 fixedly mounted on the testing platform 102. One end of the four sets of pillars 301 is connected to a top plate (not shown in the figure). Multiple sets of hydraulic cylinders 302 are fixedly mounted on the top plate. The output ends of the multiple sets of hydraulic cylinders 302 are connected to a testing mechanism 4. The testing mechanism 4 is used to perform strength testing on the door guard plate.

[0048] like Figure 6 and Figure 9 As shown, the detection mechanism 4 includes a crossbar 401 connected to the output end of the hydraulic cylinder 302, two sets of mounting rods 409 are installed on the crossbar 401, and two sets of mounting blocks 408 are fixedly installed at both ends of the mounting rods 409, and a punching head 303 is fixedly installed through the mounting blocks 408, and fixing rods 410 are fixedly installed on both sides of the punching head 303, and the punching head 303 is fixedly connected to the bottom of the mounting block 408 through the fixing rods 410;

[0049] At the same time, a detection sleeve 411 is movably sleeved on the punch head 303, and a slide groove 420 adapted to the width of the fixed rod 410 is opened on the detection sleeve 411. The fixed rod 410 is suitable for passing through the slide groove 420, and the slide groove 420 is suitable for the detection sleeve 411 to move up and down on the punch head 303.

[0050] A mounting bracket 412 is fixedly mounted on the mounting block 408 and movably extends through the detection sleeve 411. A long slot (not shown) adapted for the mounting bracket 412 is formed on the detection sleeve 411. Side blocks 413 are fixedly mounted on both sides of the detection sleeve 411, and a first spring 414 is connected between the side blocks 413 and the mounting bracket 412 to support the detection sleeve 411.

[0051] It should be noted that: in the initial state, the first spring 414 is in a compressed state, and part of the punch head 303 is in the detection sleeve 411, and the remaining part of the punch head 303 is out of the detection sleeve 411 (such as Figure 9 shown);

[0052] like Figure 6 and Figure 8 As shown, a pressure rod 415 is slidably mounted on the detection sleeve 411. The pressure rod 415 has a protrusion. At the same time, a limiting groove (not shown) adapted to the protrusion is opened on the detection sleeve 411. The limiting groove is used to support the pressure rod 415. A second spring 416 is fixedly mounted on the protrusion, and a third electromagnet 417 is fixedly mounted on one end of the second spring 416. The second spring 416 is used to support the third electromagnet 417.

[0053] A displacement sensor 418 is fixedly installed on the side of the third electromagnet 417. The displacement sensor 418 is located inside the detection sleeve 411 and directly above the punch head 303. The displacement sensor 418 is used to detect the degree of expansion and contraction of the detection sleeve 411 to determine the degree of depression of the door guard plate. At the same time, a fourth electromagnet 419 is fixedly installed on the mounting block 408 directly above the third electromagnet 417. The detection sleeve 411 is suitable for moving up and down to drive the pressure rod 415 to move synchronously, and the displacement sensor 418 is suitable for moving with the pressure rod 415 until the third electromagnet 417 is magnetically attracted to the fourth electromagnet 419 and squeezes the second spring 416. At this time, the pressure rod 415 gradually approaches the detection end of the displacement sensor 418.

[0054] A fifth electromagnet 433 is fixedly mounted within the limiting groove, and a sixth electromagnet (not shown) is fixedly mounted on a surface of the protrusion adjacent to the fifth electromagnet 433. The protrusion is adapted to move upward in sync with the upward movement of the detection sleeve 411, so that the protrusion is magnetically attracted to the fifth electromagnet 433 via the sixth electromagnet, thereby ensuring that the detection end of the displacement sensor 418 is in contact with the pressure rod 415.

[0055] It should be noted that, in a default state, there is a certain gap between the top end of the displacement sensor 418 and the mounting bracket 412, and the pressure rod 415 is located at the bottom end of the inner wall of the limiting groove, so that the pressure rod 415 moves upward synchronously with the upward movement of the detection sleeve 411, thereby gradually approaching the detection end of the displacement sensor 418.

[0056] like Figure 8 and Figure 10 As shown, a control panel 421 is connected and installed between the two sets of detection sleeves 411. The control panel 421 has a vertically arranged first slideway 422. At the same time, a control rod 430 is hingedly installed on the bottom surface of the mounting block 408. The control rod 430 has a control ball (not shown in the figure);

[0057] A second slide 423 is connected to the first slide 422. The bottom of the second slide 423 is lower than the bottom of the first slide 422. Therefore, after the control ball slides from the first slide 422 into the second slide 423, it cannot return to the first slide 422 from the second slide 423.

[0058] A third slide 425 is connected to the second slide 423. The bottom of the third slide 425 is lower than the bottom of the second slide 423. A first step (not shown) is provided between the third slide 425 and the second slide 423. Therefore, after the control ball slides from the second slide 423 into the third slide 425, it cannot return from the third slide 425 to the second slide 423. A first vertex 424 is provided at the connection between the third slide 425 and the second slide 423. The first vertex 424 is located in the third slide 425.

[0059] A fourth slide 427 is connected to the third slide 425. The bottom of the fourth slide 427 is lower than the bottom of the third slide 425. A second step (not shown) is provided between the fourth slide 427 and the third slide 425. Therefore, after the control ball slides from the third slide 425 into the fourth slide 427, it cannot return to the third slide 425 from the fourth slide 427.

[0060] A stop point 426 for the control ball to stop is provided at the connection point between the third slide 425 and the fourth slide 427, and a first switch (not shown in the figure) is provided at the stop point 426. The first switch is used to control the third electromagnet 417, the fourth electromagnet 419, the fifth electromagnet 433, and the sixth electromagnet to be in a de-energized state. In a default state, the control ball is at the stop point 426, and the fifth electromagnet 433 and the sixth electromagnet are in a de-energized state in a default state.

[0061] A fifth slide 429 is connected to the fourth slide 427. The bottom height of the fifth slide 429 is lower than that of the fourth slide 427. A third step (not shown in the figure) is provided between the fourth slide 427 and the fifth slide 429. Therefore, after the control ball slides from the fourth slide 427 into the fifth slide 429, it cannot return from the fifth slide 429 to the fourth slide 427. A second vertex 428 is provided at the connection between the fourth slide 427 and the fifth slide 429. The second vertex 428 is located in the fifth slide 429 and has the same height as the first vertex 424. A second switch (not shown in the figure) is provided at the second vertex 428. The second switch is used to control the third electromagnet 417, the fourth electromagnet 419, the fifth electromagnet 433 and the sixth electromagnet to be in an energized state.

[0062] At the same time, the fifth slide 429 is connected to the first slide 422, and a transition slope (not shown in the figure) is provided at the connection between the fifth slide 429 and the first slide 422. The transition slope gradually rises along the position close to the first slide 422, and the highest position of the transition slope is higher than the bottom position of the first slide 422, forming a fourth step.

[0063] It should be noted that, in the initial state, the third electromagnet 417, the fourth electromagnet 419, the fifth electromagnet 433 and the sixth electromagnet are all in a power-off state;

[0064] In summary, when a door guard plate needs to be inspected, the door guard plate to be inspected is first placed on the mounting platform 202, and then the door guard plate is pressed against the mounting platform 202 by the pressing device 203. At the same time, the two sets of first cylinders 204 are activated to drive the clamping plates 205 to clamp the two sides of the door guard plate. The hydraulic cylinder 302 is activated to drive the crossbar 401 to move downward, and the crossbar 401 drives the installation rod 409 to move downward, thereby driving the punch head 303 to punch the door guard plate.

[0065] Since the punch head 303 has a downward punching force on the door guard plate, the door guard plate is slightly depressed, and as the punch head 303 punches into the door guard plate, and at the same time, since the diameter of the detection sleeve 411 is larger than the punch head 303, the detection sleeve 411 is in contact with the non-depressed surface of the door guard plate, and as the punch head 303 continues to move downward, the detection sleeve 411 is held against the non-depressed surface of the door guard plate, and relies on the holding force to move upward relative to the punch head 303, and synchronously drives the control plate 421 to move upward until the telescopic end of the hydraulic cylinder 302 moves to the specified stroke. At this time The control ball moves from the stop point 426 and abuts against the second vertex 428. At this time, the third electromagnet 417, the fourth electromagnet 419, the sixth electromagnet, and the fifth electromagnet 433 are all energized. At the same time, the detection sleeve 411 drives the pressure rod 415 to move upward synchronously. The pressure rod 415 drives and compresses the second spring 416. The second spring 416 drives the third electromagnet 417 to approach and be magnetically attracted to the fourth electromagnet 419. At this time, the detection end of the displacement sensor 418 contacts the pressure rod 415. At the same time, there is a certain distance between the sixth electromagnet and the fifth electromagnet 433.

[0066] After the hydraulic cylinder 302 completes one press, it resets. Since the control ball is at the second vertex 428 at this time, the reset of the hydraulic cylinder 302 drives the control ball to move upward. At this time, the control ball continues to move up to the uppermost position on the fifth slide 429. At this time, the control plate 421 loses the restriction of the control ball, and thus, under the action of the first spring 414, it moves downward synchronously with the detection sleeve 411, and synchronously makes the fifth electromagnet 433 approach and be magnetically attracted to the sixth electromagnet. At the same time, one end of the detection sleeve 411 is flush with the punching head 303 (as shown in FIG. Figure 12 ), and because the pressing rod 415 is magnetically attracted to the fourth electromagnet 419 by the third electromagnet 417, the pressing rod 415 remains stationary and gradually moves away from the bottom end of the inner wall of the limiting groove as the detection sleeve 411 moves downward, thereby completing the stamping work of the door guard plate;

[0067] When the hydraulic cylinder 302 is activated again, the detection sleeve 411 and the punch head 303 are synchronously moved downward. As the punch head 303 extends into the recess of the door guard plate, it simultaneously pushes the detection sleeve 411 and drives the control plate 421 upward. At this time, the control ball synchronously slides from the first slide 422 into the second slide 423, and after moving the hydraulic cylinder 302 for a specified distance, it abuts against the first vertex 424.

[0068] At the same time, the detection sleeve 411 synchronously drives the pressure rod 415 to move upward, and the pressure rod 415 squeezes the telescopic end of the displacement sensor 418 to judge the degree of depression of the door guard plate according to the detection value of the displacement sensor 418, and judge the quality of the door guard plate. After the detection is completed, the telescopic end of the hydraulic cylinder 302 is reset, and the control ball is supported at the stop point 426 under the action of the first spring 414 and presses the first switch. At this time, the third electromagnet 417, the fourth electromagnet 419, the fifth electromagnet 433 and the sixth electromagnet are all in the power-off state, and then the pressure rod 415 is no longer restricted by the fourth electromagnet 419 and is supported at the bottom end of the inner wall of the limiting groove under the action of the second spring 416, thereby restoring to the initial state, so as to facilitate the strength test of the next group of door guard plates.

[0069] Example 2: Since the above example can only perform a small-area stamping operation on the door guard plate, it is difficult to simulate the denting condition when the door guard plate is subjected to a large-area stamping in actual use, resulting in certain limitations in the test results.

[0070] In order to solve the above problems, Figure 6-Figure 7 As shown, the difference from the above embodiment is that two groups of connecting members 404 are fixedly installed on both sides of the crossbar 401, a mounting cover 405 is connected between the two groups of connecting members 404, a screw rod 406 is connected to a bearing in the mounting cover 405, and a motor 407 is fixedly installed on one end of the mounting cover 405, the output end of the motor 407 is connected to one end of the screw rod 406, and two groups of slides 431 are threadedly connected to the screw rod 406, and both ends of the mounting rod 409 are connected to the two groups of slides 431;

[0071] The screw rod 406 is adapted to rotate along with the output end of the motor 407 so as to move the two sets of slides 431 closer to or farther from each other, thereby driving the two sets of mounting rods 409 closer to or farther from each other, thereby moving the multiple sets of punching heads 303 closer to or farther from each other;

[0072] It should be noted that, in the default state, the multiple sets of punch heads 303 are located on the outer sides of the upper and lower sides of the door guard plate;

[0073] like Figure 2 and Figure 4-Figure 5 As shown, a stamping mechanism 5 is installed on the inspection platform 102. The stamping mechanism 5 is suitable for performing surface stamping operations on the door guard plate. The stamping mechanism 5 includes four groups of columns 501 fixedly installed on the inspection platform 102, and third springs 502 are sleeved on the four groups of columns 501. At the same time, a bracket plate 503 is movably sleeved on the four groups of columns 501. One end of the third spring 502 is connected to the bracket plate 503 to support the bracket plate 503.

[0074] The bracket plate 503 has a hollow groove, and slide plates 506 are fixedly installed on both sides of the inner wall of the hollow groove. A stamping plate 509 is slidably installed between the two sets of slide plates 506. A clamping groove 504 is opened at one end of the inner wall of the hollow groove, and a first electromagnet (not shown in the figure) is fixedly installed inside the clamping groove 504. At the same time, a second electromagnet 510 is fixedly installed on the end of the stamping plate 509 near the clamping groove 504.

[0075] A second cylinder 511 is fixedly mounted on the lower end of the bracket plate 503, a third magnet is fixedly mounted on the telescopic end of the second cylinder 511, and a fourth magnet (not shown) is fixedly mounted on a surface of the stamping plate 509 near the telescopic end of the second cylinder 511.

[0076] Multiple sets of fourth springs 505 are fixedly mounted on one end of the inner wall of the hollow groove near the second electromagnet 510. The fourth springs 505 are adapted to push the stamping plate 509. Multiple sets of fifth springs 507 are fixedly mounted on the lower end of the bracket plate 503. A protrusion 508 is fixedly mounted on one end of the fifth spring 507. The protrusion 508 is adapted to compress the fifth spring 507 as the bracket plate 503 moves downward, thereby pressing and securing the door guard plate.

[0077] It should be noted that the lower end of the punching plate 509 extends out of the bracket plate 503 and is located at the upper end of the protrusion 508;

[0078] Therefore, when the multiple groups of punching heads 303 approach each other, the controller 101 is first used to control the first electromagnet and the second electromagnet 510 to be energized, and the second cylinder 511 is started synchronously, so that the telescopic end of the second cylinder 511 approaches the punching plate 509, and the punching plate 509 is magnetically attracted to the telescopic end of the second cylinder 511, so as to push the punching plate 509 to one end of the inner wall of the hollow groove, until the second electromagnet 510 at one end of the punching plate 509 is magnetically connected with the first electromagnet and synchronously squeezes the fourth spring 505. At this time, the punching plate 509 is in a position above the door guard plate. At this time, since the magnetic attraction force of the first and second electromagnets 510 is greater than the magnetic attraction force of the third and fourth magnets, and as the second cylinder 511 is reset, the punching plate 509 is still magnetically attracted to the first electromagnet.

[0079] Then, by starting the hydraulic cylinder 302, the punching head 303 is driven to move downward, and the punching head 303 pushes the punching plate 509, and the punching plate 509 synchronously pushes the bracket plate 503 to move downward and squeeze the third spring 502. At this time, the protruding head 508 is suitable for moving downward synchronously with the downward movement of the bracket plate 503 to squeeze the fifth spring 507, so that the protruding head 508 can press and fix the door guard plate. At the same time, since the multiple groups of protruding heads 508 are arranged around the punching plate 509 and are in the inner position of the multiple groups of punching heads 303 in the default state, the door guard plate can be pressed and fixed through the pre-contact between the protruding heads 508 and the door guard plate The undetected center position on the door guard plate is fixed and pressed, and then the punching head 303 drives the punching plate 509 to perform surface punching on the undetected center position of the door guard plate, and as the hydraulic cylinder 302 is reset, the bracket plate 503 is restored to its initial state under the action of the third spring 502. At the same time, the quality of the door guard plate can be judged according to the degree of depression of the door guard plate after surface stamping. After the inspection is completed, the controller 101 is used to control the first electromagnet and the second electromagnet 510 to lose power again. At this time, the punching plate 509 is moved closer to the second cylinder 511 under the action of the fourth spring 505 to restore the initial state.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
