Problems solved by technology

[0002] With the development of the automobile industry, the application of automobile intelligent assisted driving technology is becoming more and more extensive. Car cameras have basically become the standard accessories of automobiles. At present, the camera pixels have increased to one million levels, and camera active calibration equipment has gradually attracted attention and been widely used in China. Application; In the existing technology, the mainstream communication method between the camera and its connected equipment is through the coaxial connector. Since the coaxial connector itself will produce structural tolerances, patch tolerances, assembly tolerances, etc. during the production process, The tolerance has reached 0.35mm, which is beyond the tolerance range of the camera coaxial connector commonly used by the camera fixture on the market, resulting in low contact stability between the high-frequency probe on the camera fixture and the coaxial connector. During the process, the lighting stability of the camera is extremely low, which seriously affects the production efficiency

Abstract

The invention relates to an automatic tolerance calibration fixture for a camera. The fixture comprises a housing, wherein the upper surface of the housing is provided with a mounting seat for mounting the camera, an upper cover for fixing the camera is arranged above the mounting seat, the upper cover is slidably coupled to the housing through a slide bar disposed on the upper surface of the housing; the bottom of the mounting seat communicates with a tolerance mechanism disposed in the housing, the tolerance mechanism is provided with a movable high frequency probe, and the high frequency probe is in communication with a coaxial connector disposed at the bottom of the camera. The fixture has the beneficial effect that the high frequency probe can move on the tolerance mechanism accordingto the position of the coaxial connector, which effectively avoids the tolerances produced by the coaxial connector during the manufacturing process, and greatly improves the contact stability and production efficiency thereof.
