The pushing column will push the automobile parts to move. When the pushing column is separated from the automobile parts, the spring sheet of the clamping spring will push the automobile parts to the side of the pushing column. Under the pressure of the lower pressure wheel, the automobile parts are swung left and right, thereby completing the dynamic detection of the fracture toughness of the automobile parts.
[0019] The beneficial effects achieved by the present invention using the above structure are as follows:
[0020] 1. The threads at both ends of the bidirectional threaded rod are in opposite directions. During the rotation of the bidirectional threaded rod, the movable plates on both sides are driven to move closer or farther away from each other. The distance between the two movable plates is adjusted according to the size of the automotive parts to be inspected, and the automotive parts are fixed by spring sheets and push columns to achieve the technical effect of fixing automotive parts.
[0021] 2. The thread direction of the threaded sleeve is the same as that of the threaded hole of the boost rod. Since the booster threaded column and the threaded hole of the booster rod are connected by threads, when the threaded sleeve rotates, the booster threaded column is driven to rotate. During the rotation of the booster threaded column, the booster threaded column moves up and down due to the threads of the threaded hole of the booster rod. The vertical movement trend of the booster threaded column on the threaded sleeve is the same as the movement direction of the threaded hole of the booster rod.

[0022] 3. When an auto part is placed on the support wheel, the bottom of the auto part will squeeze the roller of the detection piece downward, causing the detection piece to open to both sides, and then the detection piece will pull the pressure springs on both sides of the pressure sensor. The tension of the pressure spring will act on the pressure sensor in the middle. As the pressure of the lower pressure wheel on the auto part increases, the auto part will bend downward under the pressure of the lower pressure wheel, and then the elastic force of the pressure spring will change. When the toughness of the auto part is insufficient, the bottom surface of the pressure point will be broken, which will cause a sudden change in the elastic force of the pressure spring, and the feedback will be sent to the pressure sensor, thereby realizing the detection of the fracture toughness of the auto part.
[0023] 4. During the actual driving process of the car, the force points of some automobile parts are constantly changing. The rotating plate is driven by the rotating plate motor to rotate, and the column on the rotating plate drives the tail end slide to move left and right, thereby driving the push column to move left and right. The push column will push the automobile parts to move. When the push column is separated from the automobile parts, the spring sheet of the clamping spring will push the automobile parts to the side of the push column. Under the pressure of the lower pressure wheel, the automobile parts are swung left and right, completing the dynamic detection of the fracture toughness of the automobile parts.

The column 412 is provided in the tail end slide groove 421.

The I-shaped fixing plate 431 is engaged in the groove of the clamping spring fixing plate 123.
[0050] During specific use, according to the size of the automobile part to be tested, the bidirectional threaded rod 14 is rotated, and the bidirectional threaded rod 14 will drive the movable plate 12 to move, thereby adjusting the distance between the two movable plates 12 and fixing the automobile part between the spring sheet 432 and the push column 42. At the same time, the bottom of the automobile part will press the roller 341 of the detection piece 34 downward, causing the detection piece 34 to open to both sides, and then the detection piece 34 will pull the pressure springs 343 on both sides of the pressure sensor 342, and the tension of the pressure springs 343 will act on the middle pressure sensor 342.
[0051] Start the pressure regulating motor 24, the motor gear 241 drives the threaded sleeve 232 to rotate, and then drives the boost threaded column 231 to move downward. As the boost threaded column 231 moves downward, the boost bottom plate 234 fits on the pressure plate 25 and pushes the pressure plate 25 to press the pressure block 221, driving the pressure block 221. At the same time, the spring fixed top plate 222 of the pressure rod 22 will move downward, so that the pressure rod return spring 223 is compressed. When the lower pressure wheel 32 in the lower pressure rod groove 2211 moves down to the surface of the automotive part to be tested, the spring connecting plate 2313 continues to squeeze the boost The spring 233 increases the elastic force of the boost spring 233, thereby increasing the pressure of the boost base plate 234 on the pressure plate 25, that is, the pressure of the lower pressure wheel 32 on the surface of the automobile parts increases, and the pressure value is measured by the pressure measuring piece on the lower side of the boost base plate 234. When the pressure measured by the pressure measuring piece on the lower side of the boost base plate 234 reaches a predetermined value, it is fed back to the pressure regulating motor 24 to stop the motor gear 241 from rotating. At the same time, the fine-tuning knob 2311 can be manually rotated with a tool to slowly and finely increase or decrease the pressure of the lower pressure wheel 32 on the automobile parts at the predetermined pressure value.
[0052] The automobile parts will bend downward under the pressure of the lower pressure wheel 32, and then push the detection piece 34 downward, causing the detection piece 34 to further open to both sides, and further stretch the pressure measuring spring 343. The pressure measuring spring 343 transfers its own elastic force to the pressure measuring sensor 342. When the toughness of the automobile parts is insufficient, the bottom surface of the downward pressure will be broken, which will cause a sudden change in the elastic force of the pressure measuring spring 343, thereby realizing the detection of the fracture toughness of the automobile parts.
[0053] When the vehicle is actually driving, the force points of some automobile parts are constantly changing. Initially, the clamping spring 43 will generate a thrust on the automobile parts, causing the automobile parts to drive the supporting wheel 31 to roll, causing the automobile parts to move toward the side of the pushing column 42, and then the tail end slide 421 of the pushing column 42 will drive the column 412 on the rotating plate 411 to move outward, and make the column 412 stationary at the outermost side, start the rotating plate motor 41, and the rotating plate motor 41 drives the rotating plate 411 to rotate. The column 412 on the rotating plate 411 drives the tail end slide 421 to move left and right, and then drives the pushing column 42 to move left and right, and the pushing column 42 will push the automobile parts to move. When the pushing column 42 is separated from the automobile parts, the spring sheet 432 of the clamping spring 43 will push the automobile parts to move toward the side of the pushing column 42. Under the pressure of the lower pressure wheel 32, the automobile parts are swung left and right, completing the dynamic detection of the fracture toughness of the automobile parts.
[0054] The above is the overall workflow of the present invention. Just repeat this step next time you use it.
