Spin riveting equipment suitable for automobile temperature regulator

Abstract

The invention relates to spin riveting equipment suitable for an automobile temperature regulator. A spin riveting jig is jointly driven by a first driving unit and a second driving unit, and a downward pressing unit is driven by a third driving unit. When a support for inserting the automobile temperature regulator is inserted in place in an inserting positioning table of the spin riveting jig, avalve, a push rod, a temperature sensor and a spring of the automobile temperature regulator are arranged in the support, the downward pressing unit tightly presses the support under the action of the third driving unit, a left arranged limiting unit and a right arranged limiting unit act so as to tightly press the support of the automobile temperature regulator into the inserting positioning table, the downward pressing unit moves upwards under the action of the third driving unit so as to be separated from the support by a preset distance, after a valve seat of the automobile temperature regulator is aligned relative to the support, a left arranged material pressing unit and a right arranged material pressing unit act to press down and pre-tighten the valve seat so as to enable the valve seat to cling to the support, and a spin riveting head acts to finish spin riveting combination of the support and the valve seat.

Description

technical field [0001] The invention relates to the technical field of assembly of automobile thermostats, in particular to a riveting device suitable for automobile thermostats. Background technique [0002] At present, an ordinary car thermostat includes a valve, a bracket, a valve core, a valve seat, a spring and a temperature sensor. When the engine temperature rises above the initial opening temperature, the temperature sensor is heated to push the push rod to move and drive the valve to open, so that part of the coolant enters the large circulation to dissipate heat. As the engine temperature continues to rise, the valve continues to open, the coolant flow rate increases, and the heat dissipation is strengthened. When the valve reaches the fully open state, the flow rate of the large cycle reaches the maximum, the heat dissipation capacity of the cooling system reaches the limit, and the engine temperature begins to drop. As the engine temperature drops, the thermal d...

Problems solved by technology

However, there are the following problems in the actual assembly process: 1) the purchase cost of spot welding equipment is expensive, and when the thickness of the valve seat itself is large, the solder joints are not easy to form, which affects the welding strength; 2) the spot welding process will produce A large amount of welding heat will cause thermal deformation of the welding plane of the bracket, and a lot of manpower and material resources will be invested in the follow-up to level it; 3) spot welding will inevitably damage the surface coating of the bracket and the valve seat, Subsequent needs to invest a lot of manpower and material resources to repair the coating
