Description

Technical Field

[0001] This utility model relates to the field of compressors, and more specifically, to an integrated cylinder head valve plate assembly for a refrigerator compressor. Background Technology

[0002] The valve plate assembly and cylinder head used in current refrigerator compressors are both individual parts. The cylinder head is generally made of aluminum and needs to be assembled by hand. First, the valve plate, exhaust limiter, and exhaust valve plate are assembled into a single valve plate assembly. Then, the valve plate assembly is assembled a second time and placed on the cylinder head and cylinder head gasket. Finally, the intake valve plate is added. Only after two assemblies can it be fixed to the cylinder seat with screws.

[0003] The process of assembling the valve plate assembly first, and then assembling the cylinder head, intake valve plate, etc., involves many steps and requires a lot of manual handling, which affects production efficiency. At the same time, there are many similar types of individual parts, which can easily lead to mixed or incorrect assembly, resulting in quality problems in the finished product.

[0004] Moreover, the original valve plate assembly needs to be assembled manually, which is slow and each part is handled manually, which can easily cause stains and also creates the risk of mixing or misassembly. The aluminum cylinder head and valve plate assembly need to be reassembled together, and the handling process will again affect the production rhythm and the cleanliness of the parts.

[0005] There is currently no good solution. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes an integrated cylinder head valve plate assembly for refrigerator compressors, thereby overcoming the shortcomings of the prior art:

[0007] An integrated cylinder head valve plate assembly for a refrigerator compressor includes a metal cylinder head and a metal valve plate that cooperate with each other. A metal exhaust valve plate and a metal exhaust limiter are riveted to the front side of the metal valve plate. The metal valve plate, the metal exhaust limiter, and the metal exhaust valve plate together constitute the metal valve plate assembly.

[0008] A metal intake valve plate is fixedly connected to the back of the metal valve plate, and the front of the metal valve plate is fixedly connected to the metal cylinder head.

[0009] Thus, the metal cylinder head, the metal valve plate assembly (metal valve plate, metal exhaust limiter, metal exhaust valve plate), and the metal intake valve plate together constitute the single integrated cylinder head valve plate assembly.

[0010] Preferably, the metal cylinder head has a cylinder cavity facing the metal valve plate, the cylinder cavity has a welding wire groove along its edge, the welding wire groove has a welding wire ring, and the front of the metal valve plate and the cylinder cavity are welded by dissolving the welding wire ring.

[0011] Preferably, the front side of the metal valve plate is provided with a receiving groove corresponding to the metal exhaust valve plate and the metal exhaust limiter. The receiving groove, the metal exhaust valve plate, and the metal exhaust limiter are respectively provided with corresponding rivet holes. The receiving groove, the metal exhaust valve plate, and the metal exhaust limiter are riveted together through the corresponding rivet holes and rivets.

[0012] Preferably, the metal exhaust limiter and the metal exhaust valve plate can be completely embedded in the receiving groove.

[0013] Preferably, the metal valve plate, metal exhaust limiter, metal exhaust valve plate, metal intake valve plate, and metal cylinder head are made of steel or aluminum, respectively.

[0014] Preferably, the metal valve plate is formed by stamping steel plate.

[0015] Preferably, the metal cylinder head is formed by stamping steel plate.

[0016] Preferably, the back of the metal valve plate is welded together with the metal intake valve plate.

[0017] Preferably, the back of the metal valve plate and the metal intake valve piece are respectively provided with corresponding solder points.

[0018] Preferably, the four corners of the metal valve plate, the metal intake valve plate, and the metal cylinder head are respectively provided with docking holes corresponding to the cylinder seat.

[0019] Preferably, the metal exhaust valve plate is sandwiched between the metal valve plate and the metal exhaust limiter.

[0020] The beneficial effects of this product are as follows: This product has a simple structure and is easy to manufacture. The metal valve plate, metal exhaust valve plate and metal exhaust limiter can be riveted to the front of the metal valve plate, and then the metal intake valve plate is welded to the back of the metal valve plate, reducing the assembly process of the metal exhaust valve plate, metal exhaust limiter and metal valve plate; then the metal intake valve plate is welded to the metal valve plate, further reducing the secondary assembly process of the metal intake valve plate and metal valve plate, greatly reducing the assembly process.

[0021] In this product, the metal cylinder head can be stamped and then welded to the front of the metal valve plate 7 by welding wire. At the same time, the entire welding wire ring can ensure the overall sealing of the metal cylinder head, thereby realizing the integration of the metal cylinder head, metal valve plate assembly (metal steel valve plate, metal steel exhaust limiter, metal exhaust valve plate), and metal intake valve plate.

[0022] This product addresses the two-stage assembly process in existing technologies, particularly improving existing valve plate assemblies and cylinder heads. By manufacturing an integrated cylinder head valve plate assembly, the metal cylinder head, metal valve plate, metal exhaust limiter, metal exhaust valve plate, and metal intake valve plate are integrated into a single, unified part—the integrated cylinder head valve plate assembly. This eliminates the need for multiple assembly steps, improving production efficiency and ensuring part cleanliness, avoiding contamination from repeated handling. Furthermore, the integrated valve plate assembly controls the risk of mixed or incorrect assembly from the raw material stage, providing a certain level of assurance for the quality of the finished product.

[0033] An integrated cylinder head valve plate assembly for a refrigerator compressor includes a metal cylinder head 13 and a metal valve plate 7 that cooperate with each other. The metal valve plate 7 is characterized in that a metal exhaust valve plate 9 and a metal exhaust limiter 8 are riveted to the front side of the metal valve plate 7. The metal valve plate 7, the metal exhaust limiter 8, and the metal exhaust valve plate 9 together constitute the metal valve plate assembly.

[0034] A metal intake valve plate 11 is fixedly connected to the back of the metal valve plate 7, and the front of the metal valve plate 7 is fixedly connected to the metal cylinder head 13.

[0035] Thus, the metal cylinder head 13, the metal valve plate assembly (metal valve plate 7, metal exhaust limiter 8, metal exhaust valve plate 9), and the metal intake valve plate 11 together constitute the single integrated cylinder head valve plate assembly.

[0036] In one feasible embodiment, the metal cylinder head 13 is provided with a cylinder cavity 1301 facing the metal valve plate 7. The cylinder cavity 1301 is provided with a welding wire groove 1302 along its edge. A welding wire ring 14 is provided in the welding wire groove 1302. The front side of the metal valve plate 7 and the cylinder cavity 1301 are welded by dissolving the welding wire ring 14.

[0037] In one feasible embodiment, the front side of the metal valve plate 7 is provided with a receiving groove 701 corresponding to the metal exhaust valve plate 9 and the metal exhaust limiter 8. The receiving groove 701, the metal exhaust valve plate 9, and the metal exhaust limiter 8 are respectively provided with corresponding riveting holes. The receiving groove 701, the metal exhaust valve plate 9, and the metal exhaust limiter 8 are riveted together through the corresponding riveting holes and rivets 10.

[0038] In one feasible embodiment, the metal exhaust limiter 8 and the metal exhaust valve plate 9 can be completely embedded in the receiving groove 701.

[0039] In a feasible embodiment, the metal valve plate 7, the metal exhaust limiter 8, the metal exhaust valve plate 9, the metal intake valve plate 11, and the metal cylinder head 13 are preferably made of steel or aluminum.

[0040] In one feasible embodiment, the metal valve plate 7 is formed by stamping steel plate.

[0041] In one feasible embodiment, the metal cylinder head 13 is formed by stamping steel plate.

[0042] In one feasible embodiment, the back side of the metal valve plate 7 is welded to the metal intake valve plate 11.

[0043] In one feasible embodiment, the back of the metal valve plate 7 and the metal intake valve plate 11 are respectively provided with corresponding solder points 12.

[0044] In one feasible embodiment, the four corners of the metal valve plate 7, the metal intake valve plate 11, and the metal cylinder head 13 are respectively provided with docking holes 15 corresponding to the cylinder seat 16.

[0045] In one feasible embodiment, the metal exhaust valve plate 9 is sandwiched between the metal valve plate 7 and the metal exhaust limiter 8.

[0046] Working Principle: This product, after being assembled from existing cylinder head 1, cylinder head gasket 2, valve plate 3, exhaust limiter 4, exhaust valve plate 5, and intake valve plate 6 through a two-stage process, is visually indistinguishable from the finished product. The connection method between the two and the cylinder block is also consistent. Therefore, no adaptation modifications to the cylinder block or other external equipment are required, demonstrating good compatibility.

[0047] In this product, the metal valve plate 7 can be formed by stamping steel plate, and then the metal exhaust valve plate 9 is riveted to the front of the valve plate 3; at the same time, the metal intake valve plate 11 is welded to the back of the metal valve plate 7 to make it a whole; the stamped metal cylinder head 13 has a welding wire groove 1302 on the edge of the cylinder cavity 1301, and a welding wire ring 14 is provided in the welding wire groove 1302. The metal cylinder head 13 and the metal valve plate 7 are fixedly connected or welded to the metal cylinder head 13 by dissolving the welding wire ring 14, which ensures both welding strength and sealing. Finally, the metal cylinder head 13, the metal valve plate 7, the metal intake valve plate 11, the metal exhaust valve plate 9, and the metal exhaust limiter 8 become a single integrated cylinder head valve plate assembly. The components of this product can be used for production assembly after being purchased and returned to the factory, which improves production efficiency and eliminates the risk of mixed or incorrect assembly.

[0048] In summary, through the aforementioned unique technical solutions, this product features a simple structure and is easy to manufacture. This product addresses the two-stage assembly process in existing technologies, particularly improving upon existing valve plate assemblies and cylinder heads. By manufacturing an integrated cylinder head valve plate assembly, the metal cylinder head, metal valve plate, metal exhaust limiter, metal exhaust valve plate, and metal intake valve plate are integrated into a single, unified part—the integrated cylinder head valve plate assembly. This eliminates the need for multiple assembly steps, improving production efficiency and ensuring part cleanliness, avoiding contamination from repeated handling. Furthermore, the integrated valve plate assembly controls the risk of mixed or incorrect assembly from the raw material stage, ensuring a certain level of quality assurance for the finished product.
