Automatic assembling device for upper shell of engine thermostat

Abstract

The invention relates to an automatic assembling device for an upper shell of an engine thermostat. The automatic assembling device comprises a workbench and further comprises a turntable moving assembly, a magnet feeding assembly used for conveying magnets to wax package pieces on wax package positioning blocks, a first welding assembly used for grabbing cover plates from cover plate positioningblocks and welding the cover plates into upper shells on shell positioning blocks, a wiring pin feeding assembly used for conveying wiring pins to the upper shells and installing the wiring pins, a second welding assembly used for welding the magnets and the wax package pieces, and a discharging assembly grabbing the assembled upper shells and wax package pieces from a shell tool and discharges the assembled upper shells and the wax package pieces. The thermostat shell is driven to sequentially pass through the magnet feeding assembly, the first welding assembly, the wiring pin feeding assembly, the second welding assembly and the discharging assembly to be assembled by arranging a rotary plate moving assembly, the assembling efficiency is high, positioning is accurate, manpower is saved,the quality of finished products is improved, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of thermostat assembly, in particular to an automatic assembly device for an upper casing of an engine thermostat. Background technique [0002] The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, and changes the water circulation range to adjust the heat dissipation capacity of the cooling system to ensure that the engine works within a suitable temperature range. The main thermostat used is a wax type thermostat. When the cooling temperature is lower than the specified value, the delicate paraffin wax in the temperature sensing body of the thermostat is solid, and the thermostat valve closes the gap between the engine and the radiator under the action of the spring. The coolant returns to the engine through the water pump to carry out a small cycle in the engine. When the temperature of the cooling liquid reaches the specified v...
