A device for testing the tightness of a cap-like part

Abstract

This utility model discloses a device for testing the sealing performance of cap-type parts, comprising a water tank: bases are fixedly mounted on both sides of the inner wall of the water tank, and first cylinders are fixedly mounted on the top of each of the two bases. The telescopic ends of the two first cylinders are fixedly connected to one side of the bottom end of the corresponding fixed frame, and the other side of the bottom end of the two fixed frames is fixedly connected to both sides of the top end of a top frame. This device for testing the sealing performance of cap-type parts includes a turntable driven by a servo motor, on which three rotatable rods are mounted. The other end of each rod is rotatably connected to a sliding plate, enabling the spacing between the three rods to be adjusted in a coordinated manner, thus adapting to cap-type parts of different sizes and structures, and exhibiting good versatility and adaptability. Compared with existing technologies, this structural adjustment method has strong synchronization and good stability, helping to improve the uniformity of the pressing effect and the overall testing reliability of the device.
