The robot body 1 clamps the door through the door handle clamping unit 3, then pulls the door to open it, and then closes it, and repeats the above operation. By detecting the state of the door after opening and closing, it is determined whether it can withstand multiple opening and closing of the door, and whether its strength meets the requirements.

[0035] Specifically, the door handle clamping unit 3 includes two symmetrically arranged clamping jaws 301, each of which is provided with a first clamping block 302 and a second clamping block 303 arranged in an eight-shaped shape, the clamping jaw 301 is connected to a clamping bracket 305, and the connecting part of the two clamping jaws 301 is connected to the output end of a telescopic rod 304, and the telescopic rod 304 is arranged on the clamping bracket 305;

[0036] When the telescopic rod 304 is started, it can pull the point where the two clamping jaws 301 are connected to move, so that the two clamping jaws 301 are closer to or farther away from each other, so as to achieve the purpose of clamping and releasing the door handle. Each clamping jaw 301 is provided with a first clamping block 302 and a second clamping block 303 distributed in an "eight" shape. The first clamping block 302 and the second clamping block 303 in the two clamping jaws 301 can form a clamping space when clamping, and the door handle is located in the clamping space.

The angle block 508 is set to an L shape. The angle block 508 is in the scratched state. The extrusion block 507 is located between the angle block 508 and the lifting frame 506.

In the scratched state, the right-angled side of the angle block 508 is located on the outside. The robot body 1 drives the door pressure test unit 5 to move to the position of the door, scratches the door, and checks the door's anti-scratch performance. The telescopic mechanism 504 drives the lifting plate 503 and the lifting frame 506 to move, and the depth of the angle block 508 squeezing the door can be adjusted to adjust the scratch strength. When the angle block 508 is in the retracted state, the squeezing block 507 is exposed on the outside. The squeezing block 507 is pressed against the corresponding position of the door by the robot body 1, and then the door is squeezed by the telescopic mechanism 504 to check the door's anti-squeezing performance.

[0040] It should be noted that a storage groove 511 is provided in the lifting frame 506 , and when the angle block 508 is in a retracted state, the angle block 508 is located inside the storage groove 511 .

[0041] Furthermore, the door handle clamping unit 3 and the door pressure test unit 5 are both arranged on the mounting frame 4, the door pressure test unit 5 is connected to the arc block, the arc block and the mounting groove in the mounting frame 4 can rotate relative to each other, and a spacing adjustment unit 7 is installed between the door handle clamping unit 3 and the door pressure test unit 5, the relative position of the door handle clamping unit 3 and the mounting frame 4 is fixed, and the door pressure test unit 5 is pulled to rotate by the spacing adjustment unit 7 to adjust the spacing between the two, and the spacing between the door handle clamping unit 3 and the door pressure test unit 5 is adjusted according to the situation of the inspection plant area to avoid collision between the two and other components in the inspection plant area;

[0043] It should be noted that an angle limiting block 10 is provided on the end plate 2, and the angle limiting block 10 includes a left limiting surface 1001 and a right limiting surface 1002. The left limiting surface 1001 and the right limiting surface 1002 are used to limit the rotation range of the mounting frame 4, that is, to limit the rotation range of the door handle clamping unit 3 and the door pressure testing unit 5, so as to avoid the rotation angle being too large and rubbing against the robot body 1.

[0044] Working principle:

[0045] The door is inspected together with the vehicle or the door is placed on a frame that allows it to be opened and closed. The robot body 1 sends the door handle clamping unit 3 and the door pressure testing unit 5 to the position of the door to perform multiple strength tests on the door.

[0046] First, the performance of the door during opening and closing is measured. The door handle clamping unit 3 is aligned with the door. Then, the door handle clamping unit 3 is moved to the door position by the robot body 1. Then, the telescopic rod 304 is started, which drives the two clamping claws 301 to approach each other and clamp the door handle. Then, the door is opened and closed by the robot body 1 to detect the change in the strength of the door during opening and closing.

[0047] Secondly, measure the compression resistance and scratch resistance of the door. Align the door pressure test unit 5 to the door. Then, start the drive motor 8 to put the angle block 508 in a contracted state. At this time, the extrusion block 507 is exposed to the outside. The robot body 1 is used to squeeze the door. The deformation of the door during the squeezing process is measured to determine its strength.

[0048] Start the driving motor 8 and put the angle block 508 in a scratching state. At this time, the vertical side of the angle block 508 is aligned with the car door. The robot body 1 drives the angle block 508 to move and scratch along the car door to check the damage of the car door during the scratching process, so as to judge its strength.
