Description

Technical Field

[0001] This utility model relates to the technical field of compressor swashplate processing equipment, and in particular to a swashplate coating equipment. Background Technology

[0002] The swash plate is a key component of a swash plate variable displacement compressor. It is fixed to the rotating shaft and its tilt angle can be changed. As the shaft rotates, the volume of the compartment within the compressor increases or decreases, thereby achieving compression and expansion. Because the swash plate can slide relative to the iron-based sliding block seal and maintain an airtight contact, the cooling medium can be compressed or expanded within a specified space. Therefore, the swash plate is required to have high strength and good wear resistance to withstand harsh working conditions such as long-term high-speed operation and high temperature and pressure.

[0003] Currently, in the manufacturing of swashplates, surface treatment is required on both sides and the outer cylindrical surface of the swashplate to improve its wear resistance. For example, spraying or roller coating is commonly used to apply wear-resistant coatings to the sides and outer cylindrical surface of the swashplate. However, the core area of ​​the swashplate (the two end faces of the core and the inner surface of the shaft hole) cannot be coated with wear-resistant coatings. Therefore, current spraying or roller coating processes must be performed individually, and the core area of ​​the swashplate must be protected, which is cumbersome and affects production efficiency.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0028] In the description of this utility model, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0029] In the description of this utility model, references to "one embodiment" or "some embodiments" mean that one or more embodiments of the utility model include the specific features, structures, or characteristics described in connection with that embodiment. Therefore, the phrases "one embodiment," "some embodiments," "other embodiments," "and other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0030] Reference Figure 7 In some embodiments, the swash plate 100 has a plate body 101 and a core 102, with a through hole 103 extending through the core 102. In the coating process of the swash plate 100, wear-resistant coating needs to be applied to both sides and the outer circular surface of the plate body 101, but wear-resistant coating is not allowed to be applied to the core area (both end faces of the core 102 and the inner surface of the shaft hole 103).

[0031] In response to the coating process requirements of the aforementioned swashplate 100, this utility model provides a swashplate coating device, which facilitates coating operations on the disc bodies 101 of multiple swashplates 100 without requiring protection of the core area of ​​the swashplate 100, thereby improving operational convenience and production efficiency.

[0032] Reference Figure 1 and Figure 2 In some embodiments, the slant coating apparatus includes an immersion tank 10, a drive motor 20, and a clamping mechanism 30; the immersion tank 10 contains coating material. The drive motor 20 is located on the side of the immersion tank 10 and has a drive shaft 21 arranged in a horizontal direction.

[0033] Combined with reference Figure 1 and Figure 3 The clamping mechanism 30 includes an air-expanding sleeve 31, a support shaft 32, and a clamping member. The support shaft 32 passes through the interior of the air-expanding sleeve 31, which is used to mount and support multiple swashplates 100. The clamping member is located at the end of the support shaft 32 and is used to clamp and fix the multiple swashplates 100. The support shaft 32 is coaxially connected to the drive shaft 21, and parts of the swashplates 100 are immersed in the immersion box 10. The air-expanding sleeve 31 can be a product from the prior art, which can achieve a variable diameter function according to control, thereby supporting and adapting to swashplates with different shaft hole inner diameters, improving compatibility.

[0034] In the application, multiple swashplates 100 are mounted on an air-expansion sleeve 31. The air-expansion sleeve 31, support shaft 32, and clamping components cooperate to clamp multiple swashplates 100 simultaneously, resulting in high clamping efficiency and adaptability to swashplates 100 with different inner diameters, thus improving equipment compatibility. The support shaft 32 is coaxially connected to the drive shaft 21. The disc body of the swashplate 100 is immersed in the immersion box 10. When the drive motor 20 is working, the drive shaft 21 can drive the support shaft 32, air-expansion sleeve 31, and multiple swashplates 100 to rotate synchronously, thereby uniformly coating the disc body surfaces (both sides and outer circular surfaces) of multiple swashplates 100 with wear-resistant coating, ensuring coating quality. By adjusting the height of the immersion box 10, it can be ensured that only the disc body of the swashplate is immersed in the coating, eliminating the need to protect the core area of ​​the swashplate, thus saving processes and improving production efficiency.

[0035] In the application, the drive motor 20 can be a servo motor product from the prior art, and its structure and working principle are existing technologies, which will not be described in detail here. In some embodiments, the drive motor 20 can achieve stepless speed regulation, and the speed of the drive motor 20 is 0 to 1200 revolutions per minute (rpm). Specifically, during the dip coating process, the speed of the drive motor 20 is 5 to 200 revolutions per minute, preferably 150 revolutions per minute, to facilitate the uniform coating of the swashplate 100. After the dip coating is completed, the speed of the drive motor 20 is increased to 800 to 1200 revolutions per minute, preferably 1000 revolutions per minute, to facilitate the removal of excess coating from the swashplate 100.

[0036] It should be noted that the coating in the immersion tank 10 can be a high-polymer wear-resistant coating from the prior art, and the coating has low fluidity to prevent the coating from overflowing into the core area of ​​the swashplate when it rotates, while ensuring the adhesion of the coating and improving the coating quality of the swashplate. In some embodiments, the viscosity of the coating is 500 to 10,000 centipoise (cP), preferably 800 centipoise.

[0037] Furthermore, during the coating operation, the liquid level in the immersion tank 10 is lower than the height of the central axis of the drive shaft 21 of the drive motor 21. Further, after the swashplate 100 is clamped and fixed, the bottom side of the core of the swashplate 100 should be higher than the liquid level in the immersion tank 10, thereby preventing the core area of ​​the swashplate 100 from being coated with paint as well.

[0038] In some embodiments, the clamping element may include a pressure block and / or a clamping cylinder, the pressure block and / or the clamping cylinder being disposed at the end of the support shaft, and the pressure block and / or the clamping cylinder being used to clamp multiple swashplates.

[0039] Reference Figure 3In some preferred embodiments, the clamping element includes two pressure blocks 33, which are respectively disposed at both ends of the support shaft 32. The pressure blocks 33 at both ends are tightly engaged with the support shaft 32, thereby clamping and fixing the multiple swashplates 100. Further, a through hole 34 is provided in the middle of the pressure block 33, and a sealing ring 35 is provided inside the through hole 34. The end of the support shaft 32 is inserted into the corresponding through hole 33 of the pressure block 33, and the sealing ring 35 is tightly fitted with the support shaft 32, thereby ensuring the connection strength between the pressure block 33 and the support shaft 32 and preventing the pressure block 33 from coming off.

[0040] Reference Figure 6 In some embodiments, the clamping components include a retaining block 33 and a clamping cylinder 36. The retaining block 33 is located at one end of the support shaft 32, and a cylinder mounting seat 37 is located at the other end of the support shaft 32. The cylinder mounting seat 37 is detachably connected to the support shaft 32 (e.g., by a threaded connection). The clamping cylinder 36 is located on the side of the cylinder mounting seat 37 facing the swashplate 100, and the central axis of the clamping cylinder 36 is parallel to the central axis of the support shaft 32. During the clamping operation, the piston rod of the clamping cylinder 36 abuts against multiple swashplates 100, thereby clamping and fixing the multiple swashplates 100. Furthermore, the number of clamping cylinders 36 can be multiple, and the multiple clamping cylinders 36 are evenly spaced along the circumference of the support shaft 32 to ensure the stability of the installation structure.

[0041] However, this utility model is not limited thereto. In other embodiments, the clamping member can also adopt other reasonable structures, as long as it can achieve the clamping and fixing of multiple swashplates.

[0042] Reference Figure 1 In some preferred embodiments, the drive shaft 21 is coaxially connected to the support shaft 32 via a coupling 22. The coupling 21 can be a conventional coupling product capable of connecting the drive shaft 21 and the support shaft 22 and transmitting torque.

[0043] Reference Figure 2 In some preferred embodiments, a baffle 11 is provided on the side of the immersion box 10. The baffle 11 extends upward in an arc shape from the side of the immersion box 10, and the extension direction of the baffle 11 is consistent with the rotation direction X of the drive shaft 21. When the drive motor 20 drives the multiple swashplates 100 to rotate and achieve coating of the swashplates, the baffle 11 can block the paint thrown out by the swashplates 100, avoid paint splashing, and reduce paint waste.

[0044] Furthermore, a scraper 12 is provided on the inner side of the baffle 11. The scraper 12 is close to the outer circular surface of the multiple inclined plates 100. The scraper 12 is used to scrape off excess paint from the outer circular surface of the multiple inclined plates 100, control the coating thickness, and improve the coating quality.

[0045] Furthermore, a telescopic rod 13 is provided between the baffle 11 and the scraper 12. The central axis of the telescopic rod 13 is perpendicular to the central axis of the drive shaft 21. The telescopic rod 13 is used to adjust the distance between the scraper 12 and the outer circular surfaces of the multiple swashplates 100, making the equipment suitable for coating operations on swashplates of different specifications. In application, the telescopic rod 13 can be a product such as an electric push rod in the prior art, which can drive the scraper 12 closer to or further away from the swashplate as needed.

[0046] Reference Figure 4 and Figure 5 In other embodiments, the slant coating apparatus further includes a storage tank 40 and a lifting mechanism 50. The immersion box 10 is located inside the storage tank 40, and the lifting mechanism 50 is connected to the immersion box 10. The lifting mechanism 50 is used to drive the immersion box 10 to move up and down within the storage tank 40. Further, the lifting mechanism 50 can be a cylinder, hydraulic cylinder, ball screw jack, or electric push rod, etc., capable of driving the immersion box 10 to move up and down according to process requirements. For example, the lifting mechanism 50 uses a cylinder, with the cylinder body located outside and below the storage tank 40. The piston rod of the cylinder passes through the storage tank 50 and connects to the immersion box 10, and the piston rod of the cylinder is sealed to the storage tank 40 using a rubber sealing ring or similar material.

[0047] In the application, multiple swash plates 100 are mounted on the air-expansion sleeve 31, and clamping members on both sides clamp and fix the multiple swash plates 100. Parts of the disc bodies of the multiple swash plates 100 are immersed in the immersion box 10. In the immersion coating process, the speed of the drive motor 20 is 5 to 200 rpm, preferably 150 rpm. The drive motor 21 drives the multiple swash plates 100 to rotate through the support shaft 32, so that the disc bodies of the multiple swash plates 100 are coated with wear-resistant coating. After the immersion coating is completed, the speed of the drive motor 20 is increased to 800 to 1200 rpm, preferably 1000 rpm, to facilitate the removal of excess coating from the swash plates 100. While the swash plates 100 are rotating, the scraper blade 12 can scrape off excess coating from the outer circumference of the swash plates 100. The coating thrown off when the swash plates 100 are rotating can adhere to the inner side of the baffle 11. Subsequently, the lifting mechanism 50 lowers the immersion box 100 until it is completely submerged in the storage tank 40, completing the replenishment operation. Simultaneously, the paint on the inside of the baffle 11 and the paint on the scraper 12 can be absorbed into the storage tank 40, facilitating paint recycling and preventing paint from drying out. Furthermore, for slant plate products of different specifications, the height of the immersion box 10 can be adjusted using the lifting mechanism 50, ensuring that only the plate body is immersed in the paint, eliminating the need to protect the core area of ​​the slant plate, thus saving steps and improving production efficiency.

[0048] In some embodiments, the above-described swashplate coating equipment can be used to perform multiple coating operations on multiple swashplates, and the multiple swashplates can be dried after each coating to improve the coating quality and swashplate performance.

[0049] In this invention, the inclined plate coating equipment utilizes an air-expanding sleeve, a support shaft, and clamping components to simultaneously clamp multiple inclined plates, resulting in high clamping efficiency. It is also adaptable to inclined plates with different inner diameters, enhancing equipment compatibility. By adjusting the height of the immersion box, only the plate body is immersed in the coating, eliminating the need for protection of the core area of ​​the inclined plate, thus saving steps and improving production efficiency. The drive motor rotates multiple inclined plates, ensuring uniform coating of the plate surfaces and guaranteeing coating quality. Coating ejected during plate rotation adheres to the inner side of the baffle, and the scraper removes excess coating from the outer surface of the inclined plate, facilitating coating recycling and preventing coating drying.

[0050] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
