Rotary type vehicle-wheel airtightness detection machine

Abstract

The invention discloses a rotary type vehicle-wheel airtightness detection machine. The rotary type vehicle-wheel airtightness detection machine comprises a machine frame, air cylinders, an upper seal, a lower seal, a water tank, a motor, a self-made air cylinder and the like. When the rotary type vehicle-wheel airtightness detection machine is used, a vehicle wheel is placed at the upper end of the lower seal at first, air supply of the port A of the self-made air cylinder is stopped, a spring enables a guide flange to support the vehicle wheel from the lower side, and meanwhile the guide portion of the top end of the guide flange enables the vehicle wheel to be in the middle; the pressing air cylinder enables the upper seal to be pressed on the front surface of the vehicle wheel through guide posts II, the port A of the self-made air cylinder is filled with compressed air at the same time, a piston drives a cylinder rod and the guide flange to fall, and the lifting air cylinder enables the water tank to be lifted through guide posts I until the vehicle wheel is submerged. The compressed air is injected from the lower end of a hollow shaft and enters the inner cavity of the vehicle wheel through a vent hole in the upper side of a cylinder barrel, pressure is maintained for a certain period of time, meanwhile, the motor drives the hollow shaft and the vehicle wheel to rotate through a synchronous belt, and airtightness can be judged by observing whether bubbles are produced or not.

Description

technical field [0001] The invention relates to an air tightness detector, in particular to a water air tightness detector. Background technique [0002] In the production process of aluminum alloy wheels, air tightness testing is an indispensable process, which is directly related to the safety during driving; therefore, every production enterprise pays special attention to it. The traditional methods of testing airtightness are water-tightness test and helium-gastightness test. At present, the water-tightness machines used by various manufacturers do not have wheel centering devices, and their position is only roughly judged by the naked eye. When the shaped upper seal is pressed down, the front of the wheel needs to be tilted to be pressed and sealed, which is very easy to cause wear and tear on the equipment; in addition, the traditional water-air-tight machine does not have the rotation function during wheel detection, which cannot be convenient and intuitive.
