Description

Technical Field

[0001] The utility model relates to the technical field of compressor swash plate manufacturing, in particular to an auxiliary tooling applied to the compressor swash plate. Background Art

[0002] The swash plate is a key component of a swash plate variable displacement compressor. It is fixed on the rotating shaft at an angle and can change its inclination angle. As the rotating shaft rotates, the volume of the separated space in the compressor increases or decreases, thereby achieving compression and expansion.

[0003] Since the swash plate can slide relative to the iron-based slider sealing component and maintain airtight contact with each other, the cooling medium can be compressed or expanded within the specified space. Therefore, the swash plate is required to have high strength and good wear resistance to adapt to the harsh working conditions of long-term high-speed operation and high temperature and high pressure.

[0004] Current swash plate manufacturing requires surface treatment on both sides and the outer circumference of the swash plate to improve its wear resistance. For example, wear-resistant coating is sprayed on the sides and outer circumference of the plate. However, the axial end faces of the swash plate core and the inner surface of the shaft hole are not allowed to be coated with wear-resistant coating. However, current swash plate processing methods provide poor fixing and protection for the swash plate. Furthermore, the single-plate spraying method is used, resulting in low spraying efficiency, high pollution, and low paint utilization. Furthermore, it is difficult to spray uniformly on the outer circumference, resulting in poor swash plate quality. Utility Model Content

[0030] The utility model provides an auxiliary tooling for the swash plate of a compressor, which is used in the processing of the swash plate of the compressor. Figure 1 and Figure 2 The auxiliary tooling 100 includes a top frame 20 and a plurality of lifting assemblies 70 mounted on the top frame 20. The lifting assemblies 70 are used to assemble the swash plate 10, thereby securing and protecting the swash plate 10, reducing collisions with the swash plate 10, and facilitating processing of designated parts of the swash plate 10.

[0031] Specifically, refer to Figure 1 、 Figure 3 and Figure 4 The hoisting assembly 70 includes a hook 30, a connecting rod 40, a pressure block 50, and a sealing gasket 60. There are two hooks 30, each with its upper end detachably connected to the top frame 20 and a hook portion 31 at its lower end. The ends of the connecting rod 40 are respectively suspended in the hook portions 30 of the two hooks 30. The connecting rod 40 is used to pass through multiple swash plates 10. The pressure blocks 50 are located at both ends of the connecting rod 40, with the multiple swash plates 10 positioned between the pressure blocks 50 at both ends. The sealing gasket 60 is sleeved on the connecting rod 40 and positioned between adjacent swash plates 10 and between the pressure blocks 50 at both ends and the corresponding swash plates 10.

[0032] During assembly, multiple swash plates 10 and multiple sealing gaskets 60 are first interlaced and inserted into the connecting rod 40, and the number of sealing gaskets 60 is one more than the number of swash plates 10, ensuring that a sealing gasket 60 is provided on both sides of each swash plate 10; then, the pressure blocks 50 are mounted on both ends of the connecting rod 40 to clamp and limit the swash plates 10 and the sealing gaskets 60; then, the two ends of the connecting rod 40 are hung on the hook portions 31 of the two hooks 30; then, the lifting frame 20 can be driven to move by a driving mechanism such as a lifting machine, and the lifting frame 20 then drives the lifting assembly 70 to move, thereby completing the processing operation of the swash plate 10.

[0033] The auxiliary tooling 100 is used in the machining of the swash plate 10 to effectively secure the swash plate 10 and reduce the risk of collisions. Furthermore, the sealing gasket 60 and the pressure block 50 protect areas of the swash plate 10 that do not require machining, facilitating surface treatment of designated areas of the swash plate 10 and improving the surface quality of the swash plate 10. The auxiliary tooling 100 can assemble dozens of swash plates 10 at a time, significantly improving production efficiency and capacity.

[0034] It should be noted that the specific structures of the connecting rod 40, the pressure block 50 and the sealing gasket 60 can be designed and matched according to the structure and model of the swash plate 10. The pressure block 50 and the sealing gasket 60 can be made of high temperature resistant and corrosion resistant materials, such as polytetrafluoroethylene.

[0035] Reference Figure 3 and Figure 8 In some embodiments, the swash plate 10 comprises a core 11 and a plate body 12. The core 11 is generally cylindrical and defines an axial hole 13. The plate body 12 is disposed on the outer periphery of the core 11, with an acute angle formed between the plane of the plate body 12 and the central axis of the axial hole 13. During surface treatment, the first side surface 121, second side surface 122, and outer circumference 123 of the plate body 12 are coated with a wear-resistant coating. However, the axial end surfaces of the core 11 and the wall of the axial hole 13 are not permitted to be coated with the wear-resistant coating.

[0036] During assembly, the connecting rod 40 is inserted into the shaft hole 13; the sealing gasket 60 is in close contact with the axial end surface of the core of the corresponding swash plate 10. Figure 3 and 4 As shown, a sealing gasket 60 is provided between adjacent swash plates 10a and 10b. The structure of the sealing gasket 60 cooperates with the structure of the axial end faces of the core portions of the swash plates 10a and 10b. In this way, the axial end faces of the core portion 11 and the inner wall of the shaft hole 13 can be sealed and protected to prevent these areas from being contaminated during the processing.

[0037] Reference Figure 3 and Figure 6 In some embodiments, the connecting rod 40 comprises a main section 41 and hanging sections 42 disposed at both axial ends of the main section 41. The outer diameter of the main section 41 is larger than that of the hanging sections 42. The pressure block 50, sealing gasket 60, and swash plate 10 are all sleeved onto the main section 41. A beveled transition is used between the hanging sections 42 and the main section 41 to avoid stress concentration and facilitate sleeve installation of the swash plate 10, sealing gasket 60, and pressure block 50 onto the main section 41. Furthermore, the connecting rod 40 can be made of seamless steel pipe, which offers advantages such as light weight, corrosion resistance, high temperature resistance, deformation resistance, and anti-static properties.

[0038] Reference Figure 7In some embodiments, a through hole 51 is provided within the pressure block 50, and the structure of the through hole 51 matches that of the connecting rod 40. A sealing ring 52 is coaxially disposed within the through hole 51. The pressure block 50 is sleeved onto the connecting rod 40, and the sealing ring 52 is tightly fitted against the outer wall of the connecting rod 40. The sealing ring 52 can be made of a high-temperature and corrosion-resistant material, such as polytetrafluoroethylene. The sealing ring 52 can enhance the sealing performance between the pressure block 50 and the connecting rod 40, thereby enhancing the protection of the swash plate 10 and preventing process liquids from passing through the through hole 51 and entering the axial hole 13 of the swash plate 10 during processing.

[0039] Reference Figure 1 and Figure 2 In some embodiments, the top frame 20 includes an outer frame 21 and multiple cross bars 22. The multiple cross bars 22 are arranged in parallel in the outer frame 21. Each cross bar 21 is provided with multiple pairs of hook holes 221. Each pair of hook holes 221 corresponds to a group of lifting components 70. The structure of the hook holes 221 matches the upper end structure of the hooks 31. The two hooks 30 in each group of lifting components 70 are respectively installed in the corresponding hook holes 221.

[0040] Furthermore, the top frame 20 includes a plurality of reinforcing rods 23, which are arranged in a crisscross pattern with the plurality of cross rods 22 within the outer frame 21. The plurality of reinforcing rods 23 enhance the structural strength of the top frame 20, improve the reliability and stability of the top frame 20 during operation, and extend the service life of the top frame 20. Furthermore, the outer frame 21 is provided with a plurality of mounting holes 211 to facilitate installation of the top frame 20 on a drive mechanism such as a hoist.

[0041] Reference Figure 1 and Figure 5 In some embodiments, the hook 30 and the cross bar 22 can be detachably connected using a fastening nut 32 , and the upper end of the hook 30 passes through the corresponding hook hole 221 and is connected to the corresponding fastening nut 32 .

[0042] However, the present invention is not limited thereto. In other embodiments, the top frame may adopt other reasonable structures, and the hook and the top frame may adopt other reasonable detachable connection methods.

[0043] In application, the number of the hoisting components 70, the number of swash plates 10 that can be assembled in each set of hoisting components 70, etc. can be reasonably set according to actual needs. Figure 2 As shown, in some embodiments, five cross bars 22 are provided in the outer frame 21, and each cross bar 22 is provided with three pairs of hook holes 221. Four swash plates 10 can be assembled on the connecting rods 40 in each set of lifting components 70. In this way, the auxiliary tooling 100 can assemble up to sixty swash plates 10 at the same time. After the assembly is completed, the entire device can be cleaned, silanized, dipped, and sintered, thereby greatly improving production efficiency and increasing production capacity.

[0044] In addition, the surface treatment process of the swash plate in the existing technology generally includes cleaning, sandblasting, secondary cleaning, spraying of wear-resistant coating, sintering, inspection, packaging and other processes. The spraying method is used, the spraying efficiency is low, and the outer circle of the swash plate is difficult to spray, the pollution is large, and the coating utilization rate is low.

[0045] In some embodiments of the present invention, the auxiliary tool 100 is used to perform a surface treatment process on the swash plate 10 , and the process includes the following steps:

[0046] S1: Assembly: In each set of hoisting components 70, multiple swash plates 10 and multiple sealing gaskets 60 are alternately installed on the connecting rod 40. Then, the pressure blocks 50 are mounted on both ends of the connecting rod 40 to clamp and limit the swash plates 10 and sealing gaskets 60. Then, the ends of the connecting rod 40 are hung on the hooks 31 of the two hooks 30.

[0047] S2: Cleaning: The assembled swash plate 10 and the hoisting assembly 70 are sent to a cleaning device to clean all the swash plates 10;

[0048] S3: Silanization: Immerse all the cleaned swash plates 10 in an organic silane aqueous solution to perform a silanization treatment on designated parts of the plate body 12;

[0049] S4: Dip coating: Dip all swash plates after silanization into the wear-resistant coating;

[0050] S5: sintering: the dip-coated swash plate is sintered to solidify the wear-resistant coating.

[0051] Among them, during the cleaning, silanization and dipping steps, the pressure block 50 and the sealing gasket 60 can seal and protect the two end faces of the core 11 of the swash plate 10 and the wall of the shaft hole 13 to prevent the process liquid from contaminating these areas, and facilitate the processing of the two side surfaces 121, 122 and the outer circle 123 of the disk body 12 of the swash plate 10. In the silanization step, the swash plate can be silanized using an existing organic silane aqueous solution. The time of the silanization treatment can be reasonably set according to actual conditions. The treatment process does not produce sediment, the treatment time is short, the control is simple, and it can effectively improve the adhesion of the subsequent wear-resistant coating to the swash plate 10. The dipping method has low process difficulty, good coating uniformity, and can improve the utilization rate of the coating and reduce pollution. The dipping time can be reasonably set according to actual conditions. The sintering time and temperature can be matched and set according to the model of the selected wear-resistant coating.

[0052] In summary, the utility model provides an auxiliary tooling for a compressor swash plate, which can effectively fix and protect the swash plate, reduce bumps, and facilitate surface treatment of designated parts of the swash plate, thereby improving the surface quality of the swash plate; the auxiliary tooling can assemble dozens of swash plates at a time, thereby greatly improving production efficiency and increasing production capacity.
