Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing, and in particular to an automotive parts testing device. Background Technology

[0002] When processing automotive parts, it is necessary to simulate the various environments encountered by the automotive parts during the manufacturing, assembly, transportation and use stages to determine whether the automotive parts have the ability to withstand vibrations in different environments. This method is applicable to research in various industries such as electronics, electromechanical, optoelectronics, automobiles, toys and more.

[0003] Currently, vibration testing of automotive parts is typically conducted using a vibration motor. This involves placing the automotive parts to be tested on a vibration table, then starting and adjusting the speed of the vibration motor to regulate the vibration frequency, thus achieving the purpose of vibration testing. However, existing vibration tables can only adjust the vibration frequency through the vibration motor, not the vibration amplitude. Therefore, the testing range is limited and does not comprehensively simulate the vibration environment.

[0004] In conclusion, there is an urgent need for a testing device for automotive parts that can adjust the vibration amplitude to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing devices that can only adjust the vibration frequency through a vibration motor and have a small testing range, the technical problem of this utility model is to provide a testing device for automotive parts that can adjust the vibration amplitude.

[0006] Technical solution:

[0007] An automotive parts testing device includes a support frame, a control panel, a motor, a limiting frame, a threaded rod, a movable block, a connecting rod, a pull rod, and a first placement frame. The control panel is mounted on the support frame, and the motor is mounted on the side of the support frame away from the control panel. The control panel and the motor are electrically connected. The limiting frame is connected to the left side of the motor's output shaft. A threaded rod is rotatably mounted on the limiting frame, a movable block is threadedly mounted on the threaded rod, a connecting rod is rotatably mounted on the movable block, and a pull rod is rotatably mounted on the connecting rod. The pull rod is slidably connected to the support frame, and the first placement frame is slidably mounted on the support frame. The bottom of the first placement frame is connected to the top of the pull rod.

[0008] To further explain, it also includes bidirectional screws and clamping plates. The first placement frame is symmetrically and rotatably equipped with bidirectional screws. Each of the two bidirectional screws is threaded with two clamping plates, which are symmetrically distributed and slidably connected to the first placement frame.

[0009] To further explain, it also includes pointers and rulers. Pointers are connected to both the front and rear sides of the moving block, and rulers are symmetrically connected to the left side of the limiting frame. The pointers are respectively connected to the rulers on both sides.

[0010] To further explain, it also includes protective pads; protective pads are connected to the sides of the four clamps that are close to each other.

[0011] To further explain, it also includes a second placement frame, with the second placement frame connected to both the front and rear sides of the support frame.

[0012] To further explain, it also includes rubber pads, with rubber pads connected to the bottom of the support frame.

[0013] To further explain, both the left and right sides of the bidirectional screw are connected to circular throttle handles.

[0014] To further explain, the second placement rack is L-shaped.

[0015] To further clarify, the ruler is set at an angle.

[0016] To further clarify, the clamps are square in shape.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model adjusts the amplitude of the vertical vibration of the first placement frame by rotating the threaded rod, which drives the moving block to move up and down. The vertical movement of the moving block drives the connecting rod, the pulling rod, and the first placement frame to move up and down, thus achieving the purpose of fully simulating vibration.

[0019] 2. The clamping plate of this utility model can clamp the car parts tightly when it moves inward, preventing them from falling off during vibration testing.

[0020] 3. When the pointer of this utility model moves up and down, people can record the amplitude of the test by observing the ruler scale that the pointer points to. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0029] Example 1: A testing device for automotive parts, see [reference] Figures 1-5 As shown, the device includes a support frame 1, a control panel 2, a motor 3, a limit frame 4, a threaded rod 5, a moving block 6, a connecting rod 9, a pulling rod 10, a first placement frame 11, a second placement frame 15, and a rubber pad 16. The control panel 2 is mounted on the support frame 1, and the motor 3 is mounted on the side of the support frame 1 away from the control panel 2. The control panel 2 and the motor 3 are electrically connected. The vibration frequency can be adjusted by adjusting the speed of the motor 3. The left side of the output shaft of the motor 3 is connected to the limit frame 4 via a coupling. A threaded rod 5 is rotatably mounted on the limit frame 4, and a moving block 6 is threaded onto the threaded rod 5. The moving block 6 moves up and down. The kinetic energy can adjust the vibration amplitude. A connecting rod 9 is rotatably mounted on the moving block 6, and a pulling rod 10 is rotatably mounted on the connecting rod 9. The pulling rod 10 is slidably connected to the support frame 1. A first placement frame 11 is slidably mounted on the support frame 1. The bottom of the first placement frame 11 is connected to the top of the pulling rod 10. A second placement frame 15 is connected to both the front and rear sides of the support frame 1. The second placement frame 15 is L-shaped and can hold heavy objects to increase the weight of the device and enhance stability. A rubber pad 16 is connected to the bottom of the support frame 1. The rubber pad 16 protects the ground and prevents vibration from damaging the ground.

[0030] When the device is needed, it is first placed in the designated location, and then the automotive parts to be tested are placed on the first placement rack 11. After placement, the threaded rod 5 is rotated, which causes the moving block 6 to move up and down. The moving block 6 then causes the connecting rod 9, the pulling rod 10, and the first placement rack 11 to move up and down, thus adjusting the amplitude of the vibration of the first placement rack 11. After adjustment, the motor 3 can be started and its speed adjusted via the control panel 2. The output shaft of the motor 3 rotates, causing the limit frame 4 to rotate, which in turn causes the moving block 6 to rotate, which in turn causes the connecting rod 9 to rotate, which in turn causes the pulling rod 10 and the first placement rack 11 to move up and down, allowing the automotive parts on the first placement rack 11 to vibrate, thereby achieving the purpose of vibration testing of the automotive parts. After the test is completed, the motor 3 can be turned off via the control panel 2.

[0031] Example 2: See Figure 6 As shown, it also includes a bidirectional screw 12, clamping plates 13, and protective pads 14. The bidirectional screw 12 is symmetrically and rotatably mounted on the first placement frame 11. Circular handles are connected to both sides of the bidirectional screw 12 to facilitate rotation. Two clamping plates 13 are threaded onto each of the two bidirectional screws 12. The clamping plates 13 are symmetrically distributed and square in shape. The clamping plates 13 are slidably connected to the first placement frame 11. The inward movement of the clamping plates 13 can clamp the car parts to prevent them from falling. Protective pads 14 are connected to the sides of the four clamping plates 13 that are close to each other. The protective pads 14 are used to prevent slippage and also to protect the car parts.

[0032] Once the car parts are in place, the double-ended screw 12 can be rotated. The rotation of the double-ended screw 12 can drive the clamping plate 13 to move inward, thereby clamping the car parts and preventing them from falling off during vibration testing.

[0033] See Figure 4 As shown, it also includes a pointer 7 and a ruler 8. The pointer 7 is connected to both the front and rear sides of the moving block 6. The ruler 8 is symmetrically connected to the left side of the limiting frame 4. The pointer 7 points to the ruler 8 on both sides. The ruler 8 is tilted to make it easier for people to see the scale. The pointer 7 is used to point to the scale on the ruler 8 for easy recording.

[0034] When the moving block 6 moves up and down, it can drive the pointer 7 to move up and down. Then, people can record the test amplitude by watching the scale of the ruler 8 pointed to by the pointer 7, which is convenient for people to use.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
