Description

Technical Field

[0001] This utility model relates to the field of automotive performance testing technology, and in particular to a stable automotive component performance testing mechanism. Background Technology

[0002] After automotive parts are manufactured, they need to be tested. The side panel of a car is the skirt part composed of the front and rear bumpers. It is a large enclosure, and its performance needs to be tested before it can be used.

[0003] A search revealed that CN220525268U discloses a vehicle side vibration testing mechanism. This mechanism uses a cam rotation mechanism installed below a mounting plate to move the mounting plate up and down, while springs at both ends of the mechanism cause the mounting plate to vibrate. However, the cams on the cam rotation mechanism installed below the mounting plate are placed horizontally, and the cams on the rotating shaft are evenly distributed below the mounting plate. This causes the elastic force of the springs to be nonlinear under different compressions and tensions. When the cams rotate, the different forces on the springs at both ends of the platform cause uneven vibration amplitude at both ends, resulting in some springs being under overcompression and undergoing fatigue fracture.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4A stable automotive component performance testing mechanism includes a base 1. Multiple vibration connection components are bolted to the protruding portions on both sides of the base 1. Each vibration connection component includes a cylinder 7, which is bolted to the base 1. A telescopic rod 15 is bolted to the inner wall of the bottom of the cylinder 7. A disc 5 is bolted to the extended end of the telescopic rod 15. A column 13 is bolted to the upper surface of the disc 5. A clamping platform 6 is bolted to the top between the multiple columns 13. The clamping platform 6 has an internal structure... The clamping assembly has a spring 14 sleeved on the outside of the telescopic rod 15, with both ends of the spring 14 fixed to the cylinder 7 and the disc 5 respectively. A housing 8 is bolted to the upper surface of the base 1, and two support frames 23 are bolted to the upper surface of the housing 8. A rotating shaft 22 is rotatably connected between the two support frames 23, and eccentric wheels 20 are keyed to both ends of the rotating shaft 22. A connecting rod 19 is rotatably connected to one side of each eccentric wheel 20. Two guide frames 18 are bolted to the inner wall of one side of the housing 8, and the tops of both guide frames 18 are inserted into... A sliding push rod 16 is provided, and the bottom end of the push rod 16 is rotatably connected to the top end of the connecting rod 19. The housing 8 contains a power assembly that drives the rotating shaft 22 to rotate. A rubber block 17 is adhered to the top end of the push rod 16, and the rubber block 17 contacts the bottom outer wall of the clamping platform 6. The rubber block 17 protects the bottom of the clamping platform 6, preventing direct contact between the clamping platform 6 and the push rod 16, thus avoiding significant wear. The rubber block 17 is located in the middle of the bottom of the clamping platform 6. The power assembly causes the rotating shaft 22 to rotate, thereby causing the eccentric wheel 20 to... The moving link 19 moves, causing the push rod 16 to move upward along the guide frame 18. At this time, the rubber block 17 moves upward, which can push the clamping platform 6 to move upward. Simultaneously, the telescopic rod 15 extends, and the spring 14 extends, causing the disc 5 to drive the clamping platform 6 to move upward through the column 13. Then, the eccentric wheel 20 continues to rotate, driving the link 19 to move, causing the push rod 16 to move downward. At this time, the spring 14 rebounds and contracts, causing the clamping platform 6 to move downward. This cycle repeats, making it convenient for staff to conduct vibration tests on the side of the car.

[0025] In this utility model, it should be noted that the clamping assembly includes a bidirectional lead screw 12, which is rotatably connected inside the clamping platform 6. Two clamping blocks 9 are threadedly connected to the outer side of the bidirectional lead screw 12. Rotation of the bidirectional lead screw 12 causes the clamping blocks 9 to move towards the center until they contact the car side panel, thus clamping and positioning the car side panel. Two second guide rods 11 are bolted inside the clamping platform 6, and these second guide rods 11 are slidably connected to the clamping blocks 9. The second guide rods 11 guide the clamping blocks 9, enabling them to move stably. The power assembly includes a motor, which is bolted to the bottom inner wall of the housing 8. A mounting bracket is bolted to the bottom inner wall of the housing 8. Pulleys 21 are keyed to the top of the mounting bracket and the outer side of the rotating shaft 22, and the pulleys 21 communicate with each other. The motor output shaft is connected via a belt drive, with one end fixed to its adjacent pulley 21. The rotation of the motor causes the pulley 21 to rotate, which in turn causes the shaft 22 to rotate. A protective cover 4 is rotatably connected to the top of the clamping platform 6. The protective cover 4 is fixed to the clamping platform 6 by a buckle 3. The protective cover 4 can protect the top of the clamping platform 6. The protruding parts on both sides of the base 1 are fixed with first guide rods 10 by bolts, and the first guide rods 10 are slidably connected to the clamping platform 6. The first guide rods 10 can guide the clamping platform 6 so that it can move up and down stably. The inner walls on both sides of the protective cover 4 are provided with clearance grooves, which can accommodate the movement of the first guide rods 10. One end of the bidirectional lead screw 12 passes through the clamping platform 6 and is fixed with a handwheel 2 by bolts, which makes it convenient for the operator to rotate the bidirectional lead screw 12.

[0026] Working principle: In use, first open the protective cover 4, place the car side panel in the middle position inside the clamping platform 6, then turn the handwheel 2 to make the double-acting screw 12 drive the clamping blocks 9 to move towards the center until the clamping blocks 9 contact the car side panel, so that the car side panel is clamped and positioned. Then start the motor. The motor rotation causes the pulley 21 to drive the rotating shaft 22 to rotate, thereby causing the eccentric wheel 20 to drive the connecting rod 19 to move, and then the top rod 16 to move upward along the guide frame 18. At this time, the rubber block 17 moves upward, which can push the clamping platform 6 upward. At the same time, the telescopic rod 15 extends and the spring 14 extends, thereby causing the disc 5 to drive the clamping platform 6 upward through the column 13. Then the eccentric wheel 20 continues to rotate, driving the connecting rod 19 to move, causing the top rod 16 to move downward. At this time, the spring 14 rebounds and contracts, thereby causing the clamping platform 6 to move downward. This cycle is repeated, which makes it convenient for the staff to conduct vibration tests on the car side panel.

[0027] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
