Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a cleaning process equipment for cleaning blind holes in junction holes. Background Technology

[0002] In automotive air conditioning systems, the expansion valve plays a crucial role. Installed at the evaporator inlet, it is responsible for throttling and controlling the refrigerant flow. High-temperature, high-pressure liquid refrigerant is throttled through the expansion valve's orifice, transforming into low-temperature, low-pressure mist-like hydraulic refrigerant, creating the necessary conditions for the subsequent evaporation process. With the development of the automotive industry and the increasing demands on air conditioning system performance, electronic expansion valves, with their advantages of fast response and wide adjustment range, are widely used in the air conditioning systems of mid-to-high-end vehicles, demonstrating a broad market prospect.

[0003] During the manufacturing process of automotive expansion valves, aluminum shavings can easily remain inside the joint holes and blind holes. If these aluminum shavings are not thoroughly removed, they may flow with the refrigerant during the expansion valve's operation, causing wear on internal parts, affecting the accuracy of its throttling and flow control, thereby reducing the cooling effect of the air conditioning system, and potentially even causing the entire air conditioning system to malfunction, increasing vehicle repair costs and safety hazards.

[0004] Currently, the common method for cleaning aluminum shavings in the junction holes and blind holes of automotive expansion valves is to manually use an air gun to repeatedly blow them clean.

[0005] However, this cleaning method has many drawbacks: on the one hand, manual operation makes it difficult to ensure that the force and angle of each blow are consistent, resulting in unstable cleaning effects. For some complex structures such as junction holes and blind holes, aluminum shavings are difficult to remove completely. On the other hand, manual cleaning is inefficient and cannot meet the needs of large-scale production, thus increasing production costs.

[0006] Based on this, the present invention designs a cleaning process equipment for cleaning blind holes at junctions to solve the above problems. Utility Model Content

[0046] Effect: The expansion valve is placed on the upper end of the first clamping block 217 and the second clamping block 218 by the feeding assembly. The first cylinder 211 is started and drives the first mounting plate 212 to move. The first mounting plate 212 drives the first connecting plate 213 to move together.

[0051] The air blowing assembly comprises two parts: the first part is a first high-pressure air pipe 32 and a second high-pressure air pipe 33, and the second part is a third high-pressure air pipe 34. The first high-pressure air pipe 32, the second high-pressure air pipe 33, and the third high-pressure air pipe 34 are all fixedly installed on the upper end of the support plate 31.

[0052] Effect: The air vents, junction holes, and blind holes of the expansion valve are all connected. After the cleaning cycle is completed, a high-pressure air pump is used to blow out high-pressure gas through the first high-pressure air pipe 32 and the second high-pressure air pipe 33. The gas is used to clean the flushed blind holes and junction holes through the air vents, and the outer surface of the expansion valve is dried through the third high-pressure air pipe 34.

[0053] This invention quickly dries the moisture in blind holes and junction holes, preventing the expansion valve from rusting or corroding due to moisture residue, and effectively ensuring the product's service life and performance.
