Description

Technical Field

[0001] This utility model relates to the technical field of shell testing equipment, and in particular to a pressure testing device for automobile shells. Background Technology

[0002] During automobile production, the compressive strength of the outer shell must be tested. If the outer shell is displaced during the test, it will affect the test results. Furthermore, the sudden application of pressure during the test can cause damage to the testing equipment, and in severe cases, it may directly damage the testing equipment.

[0003] In practice, the existing technology for fixing the car body shell during inspection is relatively simple, which leads to unstable equipment fixation during various subsequent operations, resulting in poor work accuracy. It also requires a large amount of power to assist in the operation, increasing the overall cost of use and installation, and causing many inconveniences.

[0004] Therefore, this utility model provides a pressure detection device for automobile shell. Utility Model Content

An electric telescopic rod is fixedly connected to the top of the fixed frame. The output end of the electric telescopic rod passes through the fixed frame and is fixedly connected to a connecting shaft. A testing pressure plate is fixedly connected to the bottom of the connecting shaft. A limit groove is formed below the testing pressure plate and inside the testing platform.

[0008] The pressure testing chamber is equipped with an auxiliary pressure testing mechanism extending below the testing plate. The auxiliary pressure testing mechanism includes a positioning plate.

[0015] By setting up a pressure detection box, a drive positioning mechanism, an auxiliary pressure detection mechanism, and a secondary positioning mechanism, the control panel is opened during use.

The bottom of the auxiliary pressure detection mechanism is limited by the first fixed block, the second fixed block, and the support column, while one side of the auxiliary pressure detection mechanism is limited by the positioning plate. This facilitates the adjustment of the auxiliary pressure detection mechanism and the pressure...

[0039] Working principle:

[0040] like Figures 1-7 As shown:

[0041] By setting up a pressure detection box 1, a drive positioning mechanism 2, an auxiliary pressure detection mechanism 3, and a secondary positioning mechanism 4, when in use, the control panel 12 is opened, and the adjustment screw 44 is rotated by manually adjusting the rotating handle. Under the limitation of the second limit slide bar 45 and the moving slider 46, the protective positioning plate 47 is driven to move to one side step by step, thereby assisting in the side positioning of the car body and performing secondary positioning processing, which improves the stability of the equipment during subsequent operations.

The double-fixing method improves the positioning stability of the car body, ensuring the stability of subsequent operations on the car body. During normal operation, the car body is placed on the surface of the positioning base plate 28. The electric telescopic rod 21 rotates, driving the detection pressure plate 26 to limit the top of the car body. When the electric telescopic rod 21 continues to rotate, it will drive the positioning base plate 28 along the... The limiting groove 18 wobbles slightly downwards. At this time, the bottom spring 31 and the bottom mounting screw 36 are deformed under force, activating the buffer protection effect. At this time, the bottom of the positioning base plate 28 will gradually touch and even squeeze the pressure sensor 51 to monitor the pressure value and complete a pressure test. When positioning some larger car shells or when it is necessary to fix the car shell, the protective positioning plate 47 is driven to limit one side of the car shell by rotating the adjusting screw 44.
