By setting the automatic pushing and separating component 10, it can cooperate with the support and displacement component 8 to automatically eject the tested components and can be exported in different directions according to the test results, thus completing the classified recycling without manual recycling, greatly improving the test efficiency.

[0039] In one embodiment of the present invention, please refer to Figure 2 and Figure 9 The double-end clamping unit 6 includes: a limiting clamping plate 37, a U-shaped frame 38, an electric telescopic device 39, a main control board 40, a transmission control board 41, and an ejection and separation component 42. The electric telescopic device 39 is fixedly connected to the inner bottom of the test bench 2. The top end of the electric telescopic device 39 is fixedly connected to the main control board 40. Transmission control boards 41 are rotatably connected to the two end walls of the main control board 40. The other end of the transmission control board 41 is rotatably connected to one end wall of the U-shaped frame 38. The other end wall of the U-shaped frame 38 is fixedly connected to the limiting clamping plate 37 arranged on the outer side of the top end of the test bench 2. The limiting clamping plate 37 is slidably connected to the outer wall of the top end of the test bench 2 and is used to cooperate with the lifting of the main control board 40 to complete the clamping and fixing of the components. An ejection and separation component 42 connected to the test bench 2 is arranged on the outer side of the bottom end of the main control board 40. The ejection and separation component 42 is arranged opposite to the sorting and collecting box 4 and is used to cooperate with the falling of the main control board 40 to complete the automatic ejection of the sorting and collecting box 4.

[0040] In this embodiment, the electric telescopic device 39 is an electric telescopic rod. When the electric telescopic device 39 drives the main control board 40 to move upward, the main control board 40 cooperates with the transmission control board 41 to drive the two U-shaped frames 38 to move relatively. The U-shaped frames 38 drive the limit clamping plates 37 to clamp and fix the automotive parts located on the test bench 2. When the electric telescopic device 39 drives the main control board 40 to move downward, it can not only release the fixation of the parts, but also, as the main control board 40 continues to move, drive the ejection and separation assembly 42. The ejection and separation assembly 42 can eject the two parts collection boxes 4 from the inside of the installation bottom frame 1, facilitating the recycling of the parts collection boxes 4 by people. By setting the double-end clamping unit 6, it can not only cooperate with the test bench 2 to clamp and fix the parts, ensuring the stability of the parts during testing, but also automatically eject the parts collection box 4 filled with parts, eliminating the need for manual handling and greatly improving the convenience of the parts collection box 4 during the collection process.

[0041] In one embodiment of the present invention, please refer to Figure 10 and Figure 11 , the ejection and separation assembly 42 includes: a pressure sensing box 43, a pressure guiding air pipe 44, a cooperation board 45, a pushing-away board 46, a pressure air component 47, a communicating rotating pipe 48, a support pipe 49, and an ejection component 50. The pressure sensing box 43 is arranged on the outer side of the bottom end of the main control board 40 and is fixedly connected to the test bench 2. A number of pressure guiding air pipes 44 are fixedly connected to the box wall of the pressure sensing box 43 close to the main control board 40. The pressure air component 47 is slidably connected inside the pressure guiding air pipe 44, and the top end of the pressure air component 47 is fixedly connected to the cooperation board 45. Pushing-away boards 46 are arranged between the test bench 2 and the two parts collection boxes 4. A support pipe 49 is arranged between the pushing-away board 46 and the pressure sensing box 43. A communicating rotating pipe 48 rotatably connected to the box wall of the pressure sensing box 43 is fixedly connected to the pipe wall of the support pipe 49. An ejection component 50 is slidably connected inside the support pipe 49, and the ejection component 50 is rotatably connected to the pushing-away board 46, and is used to cooperate with the air output inside the pressure sensing box 43 to realize the synchronous movement of the two pushing-away boards 46 and complete the synchronous ejection of the two parts collection boxes 4.

[0042] In this embodiment, the air compressor member 47 includes a second piston slidably connected to the inside of the pressure guiding air pipe 44 and a second push rod fixedly connected to the second piston. The other end of the second push rod is fixedly connected to the cooperation plate 45. Additionally, the ejecting member 50 includes a third piston slidably connected to the inside of the support pipe 49 and a third push rod fixedly connected to the third piston. The end of the third push rod away from the third piston is rotatably connected to the wall of the pushing-away plate 46. When the main control plate 40 moves downward, it can push the cooperation plate 45 to move downward. The cooperation plate 45 drives the second piston to move inside the pressure guiding air pipe 44, driving the air inside the pressure sensing box 43 to enter the inside of the support pipe 49 along the communicating rotating pipe 48, thereby driving the third piston to move. The third recovery cooperates with the third push rod to drive the pushing-away plate 46 to move away from the test bench 2, ejecting the component receiving box 4 from the inside of the installation bottom frame 1. By providing the ejecting and separating assembly 42, the component receiving box 4 can be automatically ejected from the inside of the installation bottom frame 1 after being filled with components. Since the component receiving box 4 filled with components is very heavy, using the pushing-away plate 46 to eject the component receiving box 4 effectively saves the consumption of manual handling and greatly improves the transfer efficiency, thereby improving the test efficiency.

[0043] In one embodiment of the present invention, please refer to Figure 2 , Figure 12 and Figure 13 , further comprising: a buffer guiding unit 5. The buffer guiding unit 5 is arranged between the component receiving box 4 and the multi-functional testing unit 7 and is connected to the installation bottom frame 1, and is used to cooperate with the installation bottom frame 1 to complete the reception and guiding of the ejected components. Among them, the buffer guiding unit 5 includes: a buffer backing plate 51, an energy reducing rod 52, an energy absorbing seat 53, a buffer disc 54, and a buffer groove 55. The buffer backing plate 51 is arranged between the installation bottom frame 1 and the test bench 2 and is rotatably connected to the frame wall of the installation bottom frame 1. The energy reducing rods 52 are symmetrically arranged on the buffer backing plate 51. One end of the energy reducing rod 52 is rotatably connected to the buffer backing plate 51, and the other end is fixedly connected with a buffer disc 54 on the outside. The buffer disc 54 is slidably connected to the buffer groove 55 arranged inside the energy absorbing seat 53. The buffer groove 55 is provided with damping liquid, and the energy absorbing seat 53 is rotatably connected to the installation bottom frame 1.

[0044] In this embodiment, during the pushing process of the component by the pushing slide plate 31, the buffer feeding unit 5 can receive the component and gently feed the component into the inner side of the sorting and collecting box 4, avoiding the component directly falling into the inner side of the sorting and collecting box 4. Specifically, the pushing slide plate 31 pushes the tested component out of the test bench 2 and lands on the buffer pad 51. Under the action of gravity, the component pushes the buffer pad 51 to flip towards the side close to the sorting and collecting box 4. The buffer disc 54, in cooperation with the damping liquid and buffer spring arranged inside the buffer groove 55, can ensure the stability and smoothness of the flipping process of the buffer pad 51. The component landing on the buffer pad 51 slides into the inner side of the sorting and collecting box 4 along the buffer pad 51, completing the recycling of the component. By setting the buffer feeding unit 5, the component can be gently fed into the inner side of the sorting and collecting box 4, avoiding the component directly falling into the inner side of the sorting and collecting box 4, and ensuring the safety of the component during recycling.

[0045] In this automotive component strength testing device, the sorting and collecting box 4 is installed on the installation bottom frame 1, and the automotive component is placed on the test bench 2. When the electric telescopic device 39 drives the main control board 40 to move upward, the main control board 40 cooperates with the transmission control board 41 to drive the two U-shaped frames 38 to perform relative movement, and the U-shaped frames 38 drive the limit clamping plates 37 to clamp and fix the automotive component located on the test bench 2.

[0046] After the component is transversely clamped and fixed, the linear electric cylinder 13 drives the measurement and control rod 16 to move up and down. The measurement and control rod 16 drives the test box 56 to move downward. The arc-shaped ring frame 17 first contacts the surface of the component, and cooperates with the test bench 2 to complete the longitudinal limitation of the component, further ensuring the stability of the component during testing. As the test box 56 continues to move downward, the strength test head 23 directly below the extrusion convex seat 20 first contacts the surface of the component, and cooperates with the continuous downward pressure of the measurement and control rod 16 to complete the strength test of this point. The adjustment motor 22 drives the adjustment rod 21 to rotate, and the adjustment rod 21 drives the extrusion convex seat 20 to move. During the movement of the extrusion convex seat 20, the remaining strength test heads 23 can be successively ejected, thereby completing the strength test of the remaining points. The displacement motor 15 can drive the positioning rod 14 to rotate, and the positioning rod 14 can drive the H-shaped seat 12 to move back and forth. When the H-shaped seat 12 moves, it will drive the test box 56 to move synchronously, thereby detecting different positions of the component.

[0047] The measurement and control rod 16 drives the test box 56 to move upward. During the movement, the device will control the solenoid valves inside the voltage stabilizing side tube 33 and the pressure transmission branch tube 36 according to the detection results. The test box 56 cooperates with the boosting plate 26 to drive the first piston to move inside the energy supply tube 27, thereby driving the air flow inside the pressure transmission and control cavity 25. When feeding, the solenoid valves inside the voltage stabilizing side tube 33 at the upper end of the lifting control tube 30 and the pressure transmission branch tube 36 at the lower end are closed, and the solenoid valves inside the pressure transmission branch tube 36 at the upper end and the voltage stabilizing side tube 33 at the lower end are opened. The air inside the pressure transmission and control cavity 25 enters the inside of the lifting control tube 30 along the upper pressure transmission branch tube 36, driving the control piston 32 to move downward. The control piston 32 drives the connecting sliding column 34 to move downward, and the connecting sliding column 34 cooperates with the push-pull rod 35 to drive the push top sliding plate 31 to move towards the test bench 2. At the same time, the push top sliding plate 31 on the other side is pulled away from the test bench 2, so as to automatically send the components on the test bench 2 into the corresponding sorting and collecting box 4, completing the automatic collection of the components;

[0048] During the pushing process of the component by the push top sliding plate 31, the push top sliding plate 31 pushes the tested component out of the test bench 2 and lands on the buffer backing plate 51. Under the action of gravity, the component pushes the buffer backing plate 51 to flip towards the sorting and collecting box 4. The buffer disc 54 cooperates with the damping liquid and buffer spring arranged inside the buffer groove 55 to ensure the stability and smoothness of the flipping process of the buffer backing plate 51. The component landing on the buffer backing plate 51 slides into the sorting and collecting box 4 along the buffer backing plate 51, completing the recycling of the component;

[0049] The electric telescopic device 39 drives the main control board 40 to move downward, which can not only release the fixation of the component, but also as the main control board 40 continues to move, the main control board 40 pushes the cooperation board 45 to move downward. The cooperation board 45 drives the second piston to move inside the pressure guiding air pipe 44, driving the air inside the pressure sensing box 43 to enter the inside of the support pipe 49 along the connecting rotating pipe 48, and then driving the third piston to move. The third recycling cooperates with the third push rod to drive the push away plate 46 to move away from the test bench 2, pushing out the sorting and collecting box 4 full of components from the installation bottom frame 1.

[0050] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
