Liquid viewing lens and production manufacturing process thereof

Abstract

The invention discloses a liquid viewing lens and a production manufacturing process thereof. The process comprises the following steps of: a, preparing a ring-shaped gasket, a glass wafer and a liquid viewing lens main body, wherein the liquid viewing lens main body is provided with a step hole communicated with an inner flow passage, the outer surface of the liquid viewing lens main body extends around the step hole to form a ring-shaped boss, the large aperture of the step hole is consistent with the outer diameter of the glass wafer and the inner diameter of the ring-shaped boss is consistent with the outer diameter of the ring-shaped gasket; b, sequentially placing an O-shaped ring and the glass wafer into a big hole of the step hole on the liquid viewing lens main body and then placing the ring-shaped gasket into the ring-shaped boss of the glass wafer; and c, placing a die of which the middle is provided with a spring at the top of the ring-shaped gasket, enabling the spring to be pressed against the ring-shaped gasket, enabling the lower edge of the die to be pressed against the outer side edge of the ring-shaped boss and applying a pressure until the ring-shaped boss is bent inwards to be buckled with the outer edge of the upper end face of the ring-shaped gasket. According to the invention, an automobile air conditioner liquid viewing lens assembly which has high transparency, is low in cost, has better sealing performance and safety and adopts a simple process can be produced.

Description

technical field [0001] The invention relates to the field of production and manufacture of automotive air-conditioning components, in particular to a sight glass and a production process thereof. Background technique [0002] Automobile air conditioner sight glass is a component installed in the automobile air conditioning system to observe the working state of the air conditioner. Like other air conditioner components, the air conditioner sight glass must also meet the sealing and high pressure performance of the automobile air conditioner. ,The auto air conditioner sight glass is installed in the auto air conditioner system, and the working state of the refrigerant in the auto air conditioner can be observed through its sealed glass window. Its main body is made of aluminum alloy, and there are threaded joints with central holes at both ends. It is connected with other components of the air conditioning system, and in the middle is a circular transparent glass window that ...
