Description
Technical Field
The invention relates to the technical field of automatic assembly, in particular to automatic assembling equipment for an automobile thermostat.
Background
The thermostat is a valve that controls a flow path of the cooling fluid. Is a thermostat, usually comprising a temperature sensing element that opens and closes the flow of air, gas or liquid by thermal expansion or contraction. The thermostat automatically regulates the water amount entering the radiator according to the temperature of cooling water, changes the circulation range of water to regulate the heat dissipating capacity of the cooling system and ensure that the engine works in a proper temperature range. The thermostat must maintain good state of technology or otherwise seriously affect the normal operation of the engine. If the main valve of the thermostat is opened too late, the engine is overheated; if the main valve is opened too early, the preheating time of the engine is prolonged, and the temperature of the engine is too low.
In summary, the thermostat functions to keep the engine from being too cold. For example, after the engine is normally operated, the temperature of the engine may be too low without the thermostat during winter cranking. At this time, the engine needs to temporarily end the water not to circulate to ensure that the engine temperature is not too low. The thermostat commonly used in automobile engine mainly has three types, namely folding type, wax type and bimetal thermocouple type. The thermostat mainly used is a wax thermostat, when the cooling temperature is lower than a specified value, the refined paraffin in the thermostat temperature sensing body is in a solid state, the thermostat valve closes a channel between the engine and a radiator under the action of a spring, and the cooling liquid returns to the engine through a water pump to perform small circulation in the engine. When the temperature of the cooling liquid reaches a specified value, the paraffin begins to melt and gradually becomes liquid, the volume is increased along with the melting of the paraffin, and the rubber tube is pressed to shrink. When the rubber tube contracts, the rubber tube acts on the push rod with upward thrust, and the push rod pushes the valve downwards to open the valve. At this time, the cooling liquid flows back to the engine through the radiator and the thermostat valve and then through the water pump to perform large circulation.
The wax type thermostat valve generally comprises a valve core consisting of a copper cup, a wax pill, a rubber sleeve, a copper cap and a needle tip, and a valve, a flange, a spring and a base are arranged to finally form the thermostat valve.
Chinese patent CN201711066473.1 discloses a tool and method for keeping a wax thermostat fully open, and the structure of the mentioned wax thermostat valve is similar to this. However, the automatic assembly technology of the existing thermostat valve is not mature, and simple and effective automatic assembly equipment is lacked.

the parts assembled by the scheme comprise a valve core main body, a base, a spring and a flange, wherein the valve core main body is provided with a valve, the protruding parts on two sides of the flange are required to be extruded inwards, two protruding lugs extending out of a through groove in the top of the flange are required to be riveted after the base and the flange are installed, and finally, the blanking of the finished automobile thermostat is finished.
The controller drives the base to move towards the second station by controlling the index plate mechanism 2, and in the process, the part of the mounting seat moving mechanism 3 moving along with the index plate mechanism 2 is contacted with the part of the mounting seat moving mechanism 3 static relative to the index plate mechanism 2, so that the gap of the mounting seat moving mechanism 3 is reduced, and the base is clamped to play a good positioning role. The controller puts the spring into the middle concave part of the base by driving the spring feeding mechanism 5.
The controller drives the base on which the spring is placed to move to the third station by controlling the index plate mechanism 2. At this time, the controller inserts the valve body, to which the shutter has been mounted, into the spring by driving the valve body feed mechanism 6.
The controller drives the workpiece to move to the fourth station by controlling the index plate mechanism 2. The controller then mounts the flange to the workpiece by controlling the flange mounting mechanism 7, with a pair of slots above the flange passing through the boss at the top of the base, while the bottom of the flange is supported by the lateral boss at the top of the base and is thereby fixed to the base, with only one degree of freedom in the vertical direction.
The controller drives the workpiece to move to the fifth station by controlling the index plate mechanism 2. And then the controller drives the riveting mechanism 8 to rivet the protrusion at the top end of the base extending out of the top of the flange, so that the protrusion deforms and expands towards the periphery, and further the protrusion is pressed on the top of the flange, so that the flange is completely fixed on the base, and the thermostat is automatically assembled.
The controller drives the thermostat which is installed to move to a fifth station by controlling the index plate mechanism 2, and the movable mechanism 3 of the installation seat is released by the compression of the fixed connection part of the movable mechanism and the rack 1 in the process so as to release the clamping state from the bottom. Then the controller takes the thermostat off the dividing plate mechanism 2 by controlling the blanking mechanism 9 to complete automatic blanking.
All the procedures are completed, and the purpose of automatically assembling the automobile thermostat is achieved.
