Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a cylinder body and a cylinder. Background Technology

[0002] Compressors are widely used in equipment such as air conditioners, refrigerators, and heat pump systems. Their structure typically includes a motor section, a compressor section, and a housing section. The compressor section contains a cylinder, which includes a cylinder body. The cylinder body not only provides a working chamber for moving parts such as rotors and vanes, but also supports components such as end caps.

[0003] Most existing cylinder bodies are made of cast iron in one piece. To ensure sufficient strength and rigidity, the cylinder body is usually designed with a large wall thickness and solid structure. While this design ensures airtightness and wear resistance, it also results in a large cylinder body weight. As the overall machine moves towards lightweight and low-cost design, the excessively heavy cylinder body brings the following problems: 1. High material costs: The large mass of the cylinder body directly leads to an increase in the amount of raw materials used, resulting in higher manufacturing costs. 2. Inconvenient assembly and transportation: The excessive weight of the parts increases the labor intensity during assembly and handling, and also increases the cost of logistics. 3. Impact on energy efficiency: In some applications, the weight of the entire machine directly affects energy consumption and system performance. An excessively heavy cylinder body is not conducive to improving overall energy efficiency.

[0004] Therefore, existing technologies urgently need an improved structural design to reduce the weight of the cylinder body while ensuring its strength, rigidity, and sealing performance, thereby reducing raw material costs and meeting the needs of lightweight and low-cost compressors. Utility Model Content

[0005] The purpose of this utility model is to provide a cylinder body to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a cylinder body comprising a main body, a first protrusion, and a second protrusion, both of which are connected to the main body. An irregular hole is provided at the connection point between the first protrusion and the main body, with a portion of the irregular hole located on the first protrusion and the other portion located on the main body. The irregular hole includes at least one positioning structure.

[0007] Furthermore, there is only one positioning structure, and the positioning structure is an arc surface.

[0008] Furthermore, there are two positioning structures, both of which are arc surfaces.

[0009] Furthermore, there are three positioning structures, all of which are arc surfaces.

[0010] Furthermore, the second protrusion is provided with a positioning hole.

[0011] Furthermore, the irregular hole is approximately triangular in shape.

[0012] Furthermore, the irregular hole is arc-shaped on the side near the center of the cylinder body.

[0013] Furthermore, the outer contour of the cylinder body is provided with a chamfered surface near the irregular hole.

[0014] Furthermore, the edge of the beveled surface is arc-shaped, and two mutually symmetrical beveled surfaces are provided at the same position on the outer contour of the cylinder body.

[0015] This utility model also provides a cylinder, including the cylinder body described above.

[0016] In summary, the beneficial effects of this utility model are as follows: This utility model reduces weight by utilizing the space provided at the connection position between the first protrusion and the main body. At the same time, by using a positioning structure to replace the original positioning hole, the cylinder body can achieve weight reduction while meeting positioning requirements. Furthermore, tests have shown that the weight-reduced cylinder body can still meet the requirements for parameters such as main body strength, rigidity, and sealing performance. However, compared with the existing technology, it can reduce raw material costs and meet the needs of compressor lightweighting and cost reduction. Attached Figure Description

Detailed Implementation

[0019] To make the technical problem to be solved by this utility model, the technical solution and the beneficial effects clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. It should be noted that the embodiments are only a detailed description of this utility model and should not be regarded as a limitation of this utility model. All features disclosed in the embodiments of this utility model, or all steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any way.

[0020] Example 1, refer to Appendix Figure 1 ~Appendix Figure 6 .

[0021] Appendix Figure 1 ~Appendix Figure 2 A prior art cylinder body design is disclosed, which includes bolt fixing holes 32 and positioning holes 31. Generally, there are four bolt fixing holes 32 and two positioning holes 31, specifically a first positioning hole 31 and a second positioning hole 33. This utility model improves upon the prior art cylinder body design as follows: This utility model provides a cylinder body including a main body 10, a first protrusion 20, and a second protrusion 30, both of which are connected to the main body 10; wherein, an irregular hole 40 is provided at the connection position between the first protrusion 20 and the main body 10, with a portion of the irregular hole 40 located in the first protrusion 20 and the other portion located in the main body 10, and the irregular hole 40 includes at least one positioning structure 41. The utility model utilizes the space provided at the connection position between the first protrusion 20 and the main body 10 to reduce weight. At the same time, the positioning structure 41 replaces the original positioning hole, which enables the cylinder body to reduce weight while meeting positioning requirements. Furthermore, tests have shown that the cylinder body with irregular holes 40 (after weight reduction) at the connection position between the first protrusion 20 and the main body 10 still meets the requirements for main body strength, rigidity, sealing performance, and other parameters. However, compared with the existing technology, it can reduce raw material costs and meet the needs of compressor lightweighting and cost reduction.

[0022] Preferably, the positioning structure 41 is an arc surface. Specifically, in the appendix... Figure 3 , 4 In the proposed solution, there is only one positioning structure 41, which is an arc surface. The first positioning hole 31 is still retained, and after testing, it can still meet the positioning requirements.

[0023] To further reduce the weight of the cylinder body, preferably, there are two positioning structures, as shown in the attached diagram. Figure 5This includes a first positioning structure 41 and a second positioning structure 42, both of which are arc surfaces. In this case, the first positioning structure 41 and the second positioning structure 42 can replace the original two positioning holes. Therefore, the first positioning hole 31 is no longer needed, and the original position of the first positioning hole 31 on the second protrusion 30 can also be reduced in weight, as shown in the attached figure. Figure 5 As shown.

[0024] Preferably, since the positioning accuracy provided by the arc-shaped surface positioning structure is slightly lower than that of the positioning hole, therefore, based on the attached... Figure 5 Furthermore, the technical solution includes three positioning structures: a first positioning structure 41, a second positioning structure 42, and a third positioning structure 43. All three positioning structures are arc surfaces, which can compensate for the defects of the arc surface positioning structure and also reduce the weight of the second protrusion 30.

[0025] Preferably, the irregular hole 40 is approximately triangular in shape, as this triangular shape maximizes weight reduction. Furthermore, when there are three positioning structures, placing them at the three vertices of the irregular hole 40 yields the best positioning effect.

[0026] Preferred options are shown in the appendix. Figure 4 The irregular hole 40 is arc-shaped on the side near the center of the cylinder body 44, and the arc shape helps to maintain the strength of the cylinder body.

[0027] Preferred options are shown in the appendix. Figure 6 The outer contour of the cylinder body has a beveled surface 45 near the irregular hole 40. The beveled surface facilitates the production of the cylinder body and makes it less likely for defects to occur at the irregular hole 40. Furthermore, the edge of the beveled surface 45 is arc-shaped 46, and two mutually symmetrical beveled surfaces 45 are provided at the same position on the outer contour of the cylinder body.
