[0030] In the prior art, in order to prevent the movement of the automobile body during the inspection, the automobile body is limited by a limit assembly. However, the limit assembly of the existing inspection mechanism clamps the two sides of the automobile body and limits the automobile body inside the limit assembly. This fixing method does not firmly fix the automobile body. When the automobile body is subjected to pressure during the inspection, it is easy to fall from the limit assembly, thereby affecting the efficiency and accuracy of the inspection. Therefore, after research, a vehicle body strength testing device is provided. When in use, a micro hydraulic rod is used to lower the hollow box, so that the positioning rod squeezes the spring. The elasticity of the spring reacts to the positioning rod, so that multiple positioning rods are fixed according to the shape of the automobile body, and the automobile body is fixed on the mounting plate to prevent the automobile body from falling due to unstable fixation when subjected to pressure. Combined with the rotation of the screw, the positioning head at the lower end of the screw fixes the automobile body on the extension plate, thereby solving the above-mentioned defects.

[0031] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] Please refer to Figure 1-Figure 8 The embodiment of the utility model provides a vehicle body strength testing device, including an external bracket 1, a symmetrical sliding rod 11 is arranged on the upper end of the external bracket 1, and a detection mechanism is movably connected to the symmetrical sliding rod 11, and the detection mechanism is used to perform strength detection on the vehicle body.

[0033] Specifically, the detection mechanism includes a moving block 4 sliding on the slide bar 11, a cylinder 41 is installed in the moving block 4, the piston end of the cylinder 41 is connected to the extrusion block 42, and a pressure sensor 43 is installed on one side of the extrusion block 42. The moving block 4 can adjust its position by moving on the slide bar 11, and the cylinder 41 moves the extrusion block 42 downward to squeeze the vehicle body. The pressure is detected by the pressure sensor 43, and the strength data of the vehicle body is obtained through a series of calculations.

[0034] In order to fix the vehicle body, a test platform 2 is arranged inside the external bracket 1, and slide rails 22 are symmetrically arranged on the upper side of the test platform 2. Both ends of the slide rails 22 are slidably connected to a fixing mechanism 5, and the fixing mechanism 5 is used to fix the vehicle body.

[0035] Specifically, the fixing mechanism 5 includes a pair of slide plates 51 respectively slidably arranged in two slide rails 22, a mounting plate 52 is connected between the pair of slide plates 51, a micro hydraulic rod 55 is symmetrically installed on the upper side of the mounting plate 52, the piston end of the micro hydraulic rod 55 passes through the mounting plate 52 and is connected to the hollow box 54, and a plurality of positioning rods 56 are slidably arranged on the lower side of the hollow box 54. After placing both sides of the vehicle body on the mounting plate 52, the positioning rods 56 are slidably connected to the hollow box 54, and then when the positioning rods 56 contact the vehicle body, the plurality of positioning rods 56 slide out different lengths according to the shape of the vehicle body to fix the vehicle body, thereby effectively preventing the vehicle body from falling off during squeezing.

[0036] Furthermore, one end of the positioning rod 56 is connected to a spring 561, and one end of the spring 561 is connected to the inner wall of the hollow box 54. The elastic action of the spring 561 can assist the positioning rod 56 to reset the positioning rod 56.

[0037] A convex plate 58 is provided on one side of the hollow box 54, and a second slide groove 59 is provided on one side of the mounting plate 52. The convex plate 58 is slidably provided in the second slide groove 59 to improve the stability of the hollow box 54 when moving.

[0038] Furthermore, a U-shaped plate 57 is provided on one side of the hollow box 54, and a movable plate 572 is slidably provided inside the U-shaped plate 57. One side of the movable plate 572 is threadedly connected to a screw 573, and a positioning head 575 is connected to the lower side of the screw 573. The screw 573 is rotated to allow the positioning head 575 to strengthen the fixation to the vehicle body. At the same time, the positioning head 575 is set to a "V" shape structure to improve the stability of the fixation to the vehicle body, and an extension plate 53 is provided on one side of the mounting plate 52 for placing the vehicle body.

[0039] A first slide groove 571 is provided on both sides of the U-shaped plate 57 , and a limit plate 574 is provided on both sides of the movable plate 572 . The limit plate 574 is slidably connected to the first slide groove 571 , so that the movable plate 572 can move stably and prevent the movable plate 572 from separating from the U-shaped plate 57 .

[0040] The slide plate 51 can be moved in the slide rail 22 to adjust according to the size of the vehicle body. In order to make the two fixing mechanisms 5 move more stably, a bidirectional screw rod 23 is rotatably set in one of the slide rails 22. The bidirectional screw rod 23 is threadedly connected to the slide plate 51. The bidirectional screw rod 23 is driven by a motor. Through the rotation of the bidirectional screw rod 23, the two slide plates 51 threadedly connected to the two ends of the bidirectional screw rod 23 are brought closer to each other, thereby achieving the purpose of adjusting the fixation of vehicle bodies of different sizes.

[0041] After the vehicle body is inspected, the two fixing mechanisms 5 no longer fix it, and the vehicle body is unloaded through the unloading port 21 opened on the upper side of the inspection platform 2. Since the storage basket 3 is arranged on the lower side of the inspection platform 2, the vehicle body falls into the storage basket 3.

[0042] In summary, the working principle of an automobile body strength testing device according to an embodiment of the utility model is as follows: according to the size of the vehicle body, the positions of the two fixing mechanisms 5 are adjusted, and the two sides of the vehicle body are placed on the mounting plate 52. The hollow box 54 is moved downward by the micro hydraulic rod 55, so that the positioning rod 56 fixes the vehicle body in the mounting plate 52, and at the same time, the screw 573 is rotated, and the positioning head 575 is used to strengthen the fixation of the vehicle body. At this time, the cylinder 41 brings the extrusion block 42 down to extrude the vehicle body. After the inspection is completed, the fixing mechanism 5 no longer fixes the vehicle body, and the vehicle body falls into the storage basket 3 through the discharge port 21.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
