[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. The performance of a compressor is affected by many factors, including the compressor housing. For example, the utility model patent with authorization announcement number CN221400853U entitled "A Compressor Housing Structure" includes a housing with an outwardly protruding mounting part on the side of the housing. The wiring terminals are installed on the mounting part. The mounting part is more protruding than the original arc surface, so it does not encroach on the internal space of the housing, and the internal components of the housing can be arranged more rationally.

[0003] However, before installing the wiring terminals, air inlet copper pipe and air outlet copper pipe, the above-mentioned housing needs to be drilled one by one. The drilling process requires first pressing a flat surface out of the arc surface of the housing, and then drilling holes on the flat surface. Since there are many holes and the direction is irregular, the process is inefficient. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of low efficiency in drilling holes in the compressor housing one by one, this utility model provides a housing flattening and punching device, which can improve the drilling efficiency of the compressor housing.

[0020] It should be noted that the housing flattening and punching device described in this utility model is used for, but not limited to, compressor housings. For ease of explanation, this utility model only uses the application of a housing flattening and punching device to a compressor housing as an example. The principle of the housing flattening and punching device applied to other types of equipment is essentially the same as that applied to a compressor housing, and will not be elaborated here.

[0021] Please see Figures 1 to 4 ,in Figure 1This is a schematic diagram of a shell flattening and punching device according to an embodiment of the present invention. The shell flattening and punching device includes a worktable 1, a contour positioning mold 2, a pressing component 3, and a first punching component 4. The contour positioning mold 2 is installed on the top surface of the worktable 1 and is adapted to the shell 6. The contour positioning mold 2 has several clearance holes 21. The pressing component 3 is installed above the contour positioning mold 2 and has several first punching components 4. Each first punching component 4 is installed on the worktable 1. The top surface of platform 1, and each first punching assembly 4 corresponds one-to-one with each relief hole 21. The first punching assembly 4 includes a round tube 41, a first round rod 42, a first driving member 43 and a second driving member 44. The first round rod 42 is slidably sleeved in the round tube 41. The first driving member 43 and the second driving member 44 are respectively used to drive the round tube 41 and the first round rod 42 to move synchronously and flatten the arc surface 61 of the housing 6. The second driving member 44 is also used to drive the first round rod 42 to break through the flattened position and extend into the relief hole 21.

[0022] In this embodiment, the fixed structure of the housing 6 is formed by the contour positioning mold 2 and the pressing component 3. Then, by setting the first round rod 42, round tube 41, first driving component 43, second driving component 44 and clearance hole 21, the arc surface 61 of the housing 6 can be flattened and punched first. Moreover, multiple first punching components 4 operate synchronously in their respective preset directions, which effectively improves the opening efficiency of the housing 6.

[0023] First, the housing 6 is inverted onto the contour positioning mold 2, so that the inner wall of the housing 6 is completely fitted with the contour positioning mold 2; then, the pressing component 3 presses the housing 6; next, the first driving component 43 and the second driving component 44 start synchronously, so that the first round rod 42 and the round tube 41 move synchronously towards the housing 6 until the arc surface 61 of the housing 6 is flattened; finally, the first driving component 43 stops, and the second driving component 44 continues to run and drives the first round rod 42 to punch a hole and then extend into the corresponding clearance hole 21.

[0024] Furthermore, both the first driving component 43 and the second driving component 44 are hydraulic cylinders.

[0025] Furthermore, the PLC control terminal is electrically connected to the first drive unit 43 and the second drive unit 44 respectively. The PLC control terminal is used to control the first drive unit 43 and the second drive unit 44 to perform the action of pressing the plane 62 first and then punching holes.

[0026] It should be noted that in the initial state, the ends of the circular tube 41 and the first circular rod 42 are coplanar, which makes it easier for the two to flatten the arc surface 61 of the shell 6 together.

[0027] It should be noted that the curved surface 61 of the shell 6 needs to be flattened first to facilitate the subsequent welding of the copper tube 7.

[0028] In one embodiment, please refer to Figures 1 to 2 The first punching assembly 4 also includes a first limiting block 45, which is fixedly connected to the top surface of the workbench 1 and located between the contour positioning mold 2 and the first punching assembly 4. The first limiting block 45 has a limiting hole 451, and the round tube 41 is slidably sleeved in the limiting hole 451.

[0029] In this embodiment, the function of the first limiting block 45 is to further improve the stability of the round tube 41 and the first round rod 42 during the flattening or punching process, and to prevent the round tube 41 or the first round rod 42 from being misaligned due to excessive force during the flattening or punching process.

[0030] In one embodiment, please refer to Figures 1 to 3 The first punching assembly 4 also includes a transmission frame 46, with both ends of the transmission frame 46 connected to the round tube 41 and the first driving member 43 respectively, and the second driving member 44 located inside the transmission frame 46 and connected to the first round rod 42 in a transmission connection.

[0031] In this embodiment, the function of the transmission frame 46 is to realize that the first round rod 42 and the round tube 41 are arranged coaxially, and the second driving member 44 is located inside the transmission frame 46, so that the first driving member 43 and the second driving member 44 do not interfere with each other, and realize the independent operation of the first round rod 42 and the round tube 41.

[0032] In one embodiment, please refer to Figures 1 to 4 It also includes a second punching assembly 5, which is installed on the top surface of the workbench 1 and located on one side of the contour positioning mold 2. The second punching assembly 5 is used to punch holes in the plane 62 of the housing 6.

[0033] In one embodiment, please refer to Figures 1 to 3 The second punching assembly 5 includes a second round rod 51, a sleeve 52, a spring 53 and a third driving member 54. The second round rod 51 is slidably sleeved in the sleeve 52 and the spring 53. The second round rod 51, the sleeve 52 and the spring 53 are all connected to the third driving member 54 in a transmission manner.

[0034] In this embodiment, the third driving component 54 is a hydraulic cylinder. The hydraulic cylinder drives the spring 53, the sleeve 52 and the second round rod 51 to move together toward the housing 6. When they contact the plane 62 of the housing 6, the sleeve 52 stops moving, the spring 53 is compressed, and the second round rod 51 begins to punch holes until the second round rod 51 extends into the corresponding clearance hole 21, thus completing the punching.

[0035] In one embodiment, please refer to Figure 1 and Figure 2The second punching assembly 5 also includes a second limiting block 55. The second limiting blocks 55 are installed in pairs on the top surface of the workbench 1 and located between the contour positioning mold 2 and the second punching assembly 5. The sleeve 52 is slidably embedded between the two second limiting blocks 55.

[0036] In this embodiment, the function of the second limiting block 55 is to further improve the stability of the sleeve 52 and the second round rod 51 during the pressing and punching process, and to prevent the sleeve 52 or the second round rod 51 from being misaligned due to excessive force during the pressing or punching process.

[0037] Furthermore, in order for the second limiting block 55 to better restrict the sleeve 52, the outer surface of the sleeve 52 is preferably of a square structure.

[0038] In one embodiment, please refer to Figure 1 and Figure 3 The pressing component 3 includes a bracket 31, a pressing block 32, and a fourth driving component 33. The bottom end of the bracket 31 is fixedly connected to the top surface of the worktable 1. The fourth driving component 33 is installed on the top of the bracket 31. The pressing block 32 is located directly above the contour positioning mold 2 and is connected to the fourth driving component 33 for transmission.

[0039] In this embodiment, the fourth driving component 33 is a hydraulic cylinder. The hydraulic cylinder drives the pressure block 32 to press down on the housing 6 on the contour positioning mold 2, thereby fixing the housing 6 and preventing the housing 6 from moving around in the punching process.

[0040] In one embodiment, please refer to Figure 1 and Figure 3 The pressure block 32 is made of rubber.

[0041] In this embodiment, the problem of damaging the surface of the shell 6 due to excessive hardness of the pressure block 32 is avoided.

[0042] In one embodiment, please refer to Figures 1 to 3 An oil trough 11 is provided on the top surface of the workbench 1.

[0043] In this embodiment, the oil tank 11 is in a closed loop around the contour positioning mold 2, so that the waste oil will flow into the oil tank 11 no matter which direction it is discharged from, thus achieving recycling.

[0044] In one embodiment, please refer to Figure 3 The top of the contour positioning mold 2 is provided with a lifting hole 22.

[0045] In this embodiment, a lifting cylinder is installed in the lifting hole 22. The movable end of the lifting cylinder passes through the lifting hole 22 from bottom to top and pushes the housing 6, so that the housing 6 is separated from the contour positioning mold 2, which facilitates the unloading of the housing 6 after processing.

[0046] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: First, the housing 6 is inverted onto the contour positioning mold 2, so that the inner wall of the housing 6 is completely fitted with the contour positioning mold 2. Then, the fourth drive component 33 drives the pressure block 32 to move downward and press the housing 6. Next, under the programming of the PLC electrical control terminal, each of the first punching assembly 4 and the second punching assembly 5 operates synchronously. Among them, the first drive component 43 and the second drive component 44 start synchronously, so that the first round rod 42 and the round tube 41 move synchronously toward the arc surface 61 of the housing 6 until the arc surface 61 of the housing 6 presses out a plane 62 with the same outer diameter as the round tube 41. Then, the first drive component 43 stops, and the second drive component 44 continues to run and drives the first round rod 42 to punch and extend into the corresponding clearance. At the same time, the third driving component 54 is activated, causing the spring 53, sleeve 52 and second round rod 51 to move toward the plane 62 of the housing 6. When the sleeve 52 presses against the plane 62 of the housing 6 and cannot move further, the spring 53 is compressed, and the second round rod 51 continues to move until the plane 62 of the housing 6 is punched. Similarly, after punching, the second round rod 51 will extend into the corresponding clearance hole 21. Finally, the second driving component 44, the first driving component 43, the third driving component 54 and the fourth driving component 33 drive their respective components to reset in sequence, thus completing the flattening and punching process of all parts of the housing 6. The operator can then manually remove the processed housing 6 from the contour positioning mold 2.

[0047] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
