Description

Technical Field

[0001] The invention relates to the technical field of strength detection devices, and in particular to a strength detection device for an automobile bracket. Background Art

[0002] The automobile fuel tank is a container for fuel in the car, and is a special container for storing hydraulic oil or hydraulic fluid in the hydraulic system. Fuel tanks can be divided into open fuel tanks and closed fuel tanks. The fuel tank bracket is generally composed of a base plate and a support plate. The mounting holes are opened on the base plate to support the fuel tank. With the continuous improvement of people's safety awareness, people's requirements for automobile fuel tank brackets are constantly increasing. In order to ensure the qualified rate of automobile fuel tank brackets, automobile fuel tank brackets of the same batch are usually sampled to test the strength of automobile fuel tank brackets.

[0003] The compressive strength test mainly evaluates the performance of the automobile fuel tank bracket when subjected to static pressure, ensuring that it can withstand the maximum load within the design range without damage. This test is usually completed through special pressure testing equipment. The automobile fuel tank bracket is placed in the test device and gradually increased pressure is applied until the automobile fuel tank bracket reaches the limit state, thereby obtaining its compressive strength data.

[0004] However, compressive strength testing only reflects the load-bearing capacity of the fuel tank bracket under static conditions. Fatigue strength is also crucial for fuel tank brackets that are subjected to dynamic or alternating loads for a long time. Fatigue strength testing is designed to evaluate whether the fuel tank bracket can maintain sufficient strength and stability during long-term use, especially when subjected to cyclic or alternating loads. This testing process usually involves more complex testing methods and equipment, such as fatigue testing machines, which can apply repeated or alternating loads to the fuel tank bracket to simulate fatigue conditions in actual use.

[0005] In the existing automobile fuel tank bracket strength testing device, in order to perform compressive strength testing and fatigue strength testing respectively, it is usually necessary to follow a certain operating process. First, the automobile fuel tank bracket to be tested is installed on the compressive strength testing device for compressive strength testing. After the test is completed, the automobile fuel tank bracket needs to be removed and replaced with a new or repaired automobile fuel tank bracket for subsequent fatigue strength testing. In this process, the removal and reinstallation of the automobile fuel tank bracket not only increases the complexity of the operation, but may also introduce additional errors and uncertainties.

An anti-fatigue detection component 11 is arranged on the second L-plate 9, and the anti-fatigue detection component 11 is used to detect the fatigue strength of another automobile bracket.

[0027] In this technical solution, the first driving component 4 can drive the workbench 2 to flip, and can clamp and fix the two brackets at the same time, and one bracket is used to test the compressive strength, and the other bracket is used to test the fatigue strength; the top surface of the support table 1 is also provided with a controller wirelessly connected to the compressive detection component 10 and the anti-fatigue detection component 11 (the controller belongs to the mature technology in the prior art, so it is not shown in the drawings of this application) When in use, first clamp one of the brackets through the clamping assembly 6 on the top surface of the workbench 2, then start the first driving assembly 4, the first driving assembly 4 controls the workbench 2 to flip clockwise, so that the clamping assembly 6 on the bottom surface of the workbench 2 faces upward, and then clamp the other bracket through the clamping assembly 6. At the same time, the bracket is located under the pressure detection assembly 10, and pressure is gradually applied to the bracket located on the top surface of the workbench 2 through the pressure detection assembly 10 until the bracket bends. At the same time, the controller will record the pressure data applied by the pressure detection assembly 10, and then By sliding the support plate 3, the support plate 3 drives the workbench 2 to move on the support platform 1 until the workbench 2 moves to the position below the second L plate 9, and then the first drive component 4 is started again.

[0029] In this embodiment: the clamping assembly 6 includes a fixed plate 61, a mounting block 63, and two clamping plates 65. One end of the fixed plate 61 is movably connected to the workbench 2, and the other end extends upward. A fixed block 62 is provided at the upper end of the fixed plate 61. The mounting block 63 is installed on the side of the fixed block 62 away from the fixed plate 61. The two clamping plates 65 are both located below the mounting block 63 and are adjacent to each other up and down. The top surface of the clamping plate 65 located above is rotatably connected to a screw 64, and the screw 64 is threadedly matched with the mounting block 63.

[0030] When in use, first place the bracket on the clamping plate 65 located below, and then rotate the screw 64 to make the clamping plate 65 located above move closer to the clamping plate 65 located below. As the distance between the two clamping plates 65 gradually decreases, the bracket is clamped and then fixed between the two sets of clamping components 6.

[0031] In this embodiment, an extension rod 66 is disposed on the top surface of the clamping plate 65 located at the bottom, and the extension rod 66 passes through the clamping plate 65 located at the top.

[0032] During use, when the staff rotates the screw 64, since the lower end of the extension rod 66 is connected to the clamping plate 65 below, and the upper end passes through the clamping plate 65 above, the clamping plate 65 will not rotate synchronously with the screw 64 when the screw 64 drives the clamping plate 65 above to move.

[0033] In this embodiment: the first driving component 4 includes a first motor 41 and a first rotating rod 42, the first motor 41 is installed on one side of one of the support plates 3, one end of the first rotating rod 42 is connected to the output shaft of the first motor 41, and the other end passes through the two support plates 3 and the workbench 2, the end of the first rotating rod 42 away from the first motor 41 is movably connected to the other support plate 3, and the first rotating rod 42 is fixedly connected to the workbench 2.

[0034] In this technical solution, the first motor 41 is installed on one side of one of the support plates 3, and a semicircular arc groove 16 is provided on one side of the other support plate 3. A limiting ring 17 is provided at the end of the rotating rod away from the first motor 41, and a limiting rod 18 is provided on the limiting ring 17, which slides with the semicircular arc groove 16. When the limiting rod 18 rotates 180° along the semicircular arc groove 16, the workbench 2 completes the flipping.

[0035] When in use, start the first motor 41, the first motor 41 drives the first rotating rod 42 and the workbench 2 to rotate, and at the same time the limiting ring 17 drives the limiting rod 18 to rotate along the semicircular arc groove 16, the limiting rod 18 rotates 180° and is limited by the semicircular arc groove 16, and the workbench 2 completes the flipping.

[0036] In this embodiment: the second driving assembly 7 includes a second motor 71, two bidirectional lead screws 72, a chain 73 and two sprockets 74. The second motor 71 is installed on one side of the workbench 2. The output shaft of the second motor 71 is connected to one end of one of the bidirectional lead screws 72. The two bidirectional lead screws 72 are both rotatably matched on the fixed plate 61. The two sprockets 74 are respectively fixedly installed on the two bidirectional lead screws 72. The chain 73 is meshed and connected with the two sprockets 74.

[0037] In this technical solution, a limit plate is provided on the bottom surface of the fixed plate 61, and the limit rod is slidably fitted in the first movable groove 5. A group of clamping components 6 are provided on each bidirectional screw 72, and the number of each group of clamping components 6 is 2.

[0038] When in use, first clamp one side of the bracket with the clamping plates 65 on the two bidirectional lead screws 72, and then the second motor 71 drives a bidirectional lead screw 72 connected to the output shaft and a sprocket 74 to rotate. The rotation of the sprocket 74 drives the chain 73 to rotate. The rotation of the chain 73 drives another sprocket 74 and another bidirectional lead screw 72 to rotate. The simultaneous rotation of the two bidirectional lead screws 72 can make the fixed plates 61 respectively located on the two bidirectional lead screws 72 move toward each other synchronously, so that the other side of the bracket is clamped with the other clamping plate 65 on the two bidirectional lead screws 72, thereby completing the fixation of the bracket. In addition, during the movement of the fixing rod 116, the limit plate synchronously slides in the first movable groove 5 to prevent the fixed plate 61 from rotating with the rotation of the bidirectional lead screw 72.

[0039] In this embodiment: the pressure resistance detection component 10 includes a hydraulic cylinder 101, a pressure plate 102, a pin 104 and a pressure sensor 103.

[0040] When the compressive strength of the bracket is tested, the hydraulic cylinder 101 is first started. The hydraulic cylinder 101 pushes the pressure plate 102 to move upward, thereby applying pressure to the bracket. When the pressure on the bracket gradually increases and produces bending deformation, the top surface of the bracket applies pressure to the ejector pin 104. The ejector pin 104 transmits the pressure to the pressure sensor 103 through the conduction end.

[0045] After one of the brackets has undergone the compressive strength test, the support plate 3 is then slid, and the support plate 3 drives the workbench 2 to move on the support table 1 until the workbench 2 moves to the position below the second L plate 9, and then the first drive component 4 is started again, and the first drive component 4 controls the workbench 2 to flip in the counterclockwise direction, so that the bracket that has undergone the compressive strength test is flipped to the bottom surface of the workbench 2, and the bracket that has not been tested is flipped to the top surface of the workbench 2, and then the third motor 111 is started, and the third motor 111 drives the second rotating rod 112 to rotate, and the second rotating rod 112 drives the fixed rod 116 and the top end of the connecting rod 113 to rotate, and the bottom end of the connecting rod 113 drives the driving rod 114 to swing up and down, and the driving rod 114 swings up and down to drive the connecting frame 115 and the impact block 117 to swing up and down, so that the two impact blocks 117 cyclically knock on the two positions of the bracket for fatigue strength testing, and the force sensor transmits the force of the impact block 117 and the microprocessor transmits the number of times the impact block 117 knocks to the controller, In this embodiment: two symmetrically distributed second mounting seats 1110 are also provided on the top surface of the horizontal plate 118, and ear plates 1111 are rotatably matched on the outer sides of the second mounting seats 1110, and the ear plates 1111 are connected to fixing rods 116, one end of the fixing rod 116 is connected to the ear plate 1111, and the other end extends outwardly and is connected to the impact block 117, and L rods 1112 are respectively connected to the opposite ends of the connecting frame 115, one end of the L rod 1112 is connected to the connecting frame 115, and the other end is respectively connected to the two ear plates 1111.
