A thermostat shell assembly and airtight testing equipment

Abstract

The invention provides thermostat shell assembling and air tight detecting equipment which comprises an equipment base. The equipment base is provided with a locating base which is provided with a sealing pad and provided with an air inlet hole for air tight testing. A pressing mechanism is arranged above the locating base. Sealing and ejecting mechanisms corresponding to a thermostat shell water pipe and a thermostat shell base sealing hole are arranged on the side face of the locating base. The sealing and ejecting mechanisms comprise a first sealing and ejecting mechanism located on the left of the locating base, a second sealing and ejecting mechanism located in the front of the locating base, and a clamping and ejecting mechanism located on the right of the locating base. In the using process, the water pipe is installed by means of the sealing and ejecting mechanisms and sealed on a thermostat shell base in a pressed manner, the sealing hole is sealed, then air supplied to an air tight testing machine enters from the air inlet hole for air tight testing, testing is carried out, after testing is finished, the air tight testing machine is closed, the sealing and ejecting mechanisms return, the water pipe can be assembled at a time, and air tight testing on a thermostat shell can be achieved. The working procedure is reduced, time for tool changing is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to thermostat shell assembly and airtight testing equipment. Background technique [0002] The function of the thermostat is to automatically adjust the amount of water entering the radiator according to the temperature of the cooling water, and change the circulation range of the water to adjust the heat dissipation capacity of the cooling system to ensure that the engine works within a suitable temperature range. The thermostat shell is assembled by the thermostat shell base, hot water inlet pipe, hot water outlet pipe, and cold water inlet pipe. The fit of the thermostat housing seat is high. In addition, the working environment of the thermostat housing often runs synchronously with the operation of the automobile engine, and the connection between the water pipe and other parts is subject to vibration. Therefore, the matching accuracy of the water pipe installatio...

Problems solved by technology

[0003] The existing processing technology is to use ordinary hydraulic presses to manually assemble in different steps. During this process, tooling is frequently replaced. Since the three water pipes of the thermostat housing are asymmetrical in size and not on the same surface, the oil pipes need to be replaced during assembly. The tooling is often poor and inefficient when controlling the position and size accuracy of the water pipe of the parts, which affects the production efficiency of the thermostat shell. Secondly, the air tightness detection process and assembly are tested separately, and the increase in the process affects the production cycle and increases the cost.
