Description

Technical Field

[0001] This utility model relates to a grinding fluid delivery device for machining valve plates of automotive air compressors. Background Technology

[0002] In the machining process of automotive air compressor valve plates, the use of grinding fluid is crucial. Grinding fluid not only lowers the temperature in the grinding zone, preventing workpiece deformation due to overheating, but also washes away impurities such as iron filings generated during grinding, maintaining the cleanliness of the machined surface and thus improving machining accuracy and surface quality. However, existing grinding fluid delivery systems have some problems in practical applications.

[0003] During the recycling process, grinding fluid easily mixes with a large amount of iron filings and impurities. If these impurities are not filtered and removed in a timely and effective manner, they will re-enter the grinding area with the grinding fluid, leading to a decline in the surface quality of the machined product and even scratching the workpiece surface, thus affecting the product qualification rate. In addition, the accumulation of impurities may also clog the grinding fluid delivery pipes and nozzles, affecting the normal supply of grinding fluid and thus interfering with the smooth progress of the entire processing. In view of this, this utility model proposes a grinding fluid delivery device for the machining of automotive air compressor valve plates to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example:

[0034] like Figure 1-8 As shown, this embodiment proposes a grinding fluid delivery device for machining valve plates of automotive air compressors, including a pump body 10, on which an inlet pipe 12 and an outlet pipe 11 are provided;

[0035] A filter housing 20 is provided on the liquid inlet pipe 12, and a filter cylinder 40 is provided inside the filter housing 20. Multiple sets of cylinder filter holes 41 are evenly opened on the surface of the filter cylinder 40. A cover plate 30 is provided on the filter housing 20 by bolts. The cover plate 30 is connected to the filter housing 20, so that the filter cylinder 40 is rotatably disposed in the filter housing 20. The filter housing 20 is also provided with a drive assembly. The drive assembly cooperates with the filter cylinder 40, so that the filter cylinder 40 reciprocates and is disposed in the filter housing 20.

[0036] In this embodiment, when the valve plate of the automotive air compressor is being ground, the grinding fluid is introduced into the filter cylinder 40. Then the pump body 10 is turned on to deliver the grinding fluid to the grinding area. The grinding fluid in the grinding area is then introduced back into the filter cylinder 40. At the same time, the drive assembly is turned on to make the filter cylinder 40 reciprocate and filter the iron filings through the filter holes 41 in the cylinder.

[0037] By setting a filter housing 20 and a filter cylinder 40 on the liquid inlet pipe 12, and cooperating with the drive assembly to make the filter cylinder 40 reciprocate, iron filings in the grinding fluid can be effectively filtered, improving the cleanliness of the grinding fluid, thereby improving the quality and efficiency of grinding, while avoiding iron filings clogging the grinding equipment, extending the service life of the equipment, and reducing maintenance costs.

[0038] The reciprocating rotation of the filter cylinder 40 effectively prevents iron filings in the grinding fluid from clogging the filter holes 41 in the cylinder, ensuring a smooth filtration process. At the same time, its rotation helps to shake off the iron filings adhering to the surface of the filter cylinder, further improving filtration efficiency, extending the service life of the filter cylinder 40, reducing maintenance costs, and ensuring the stable operation of the grinding fluid delivery device.

[0039] The reciprocating rotating filter cartridge 40 allows for thorough mixing of various components in the grinding fluid, improving mixing uniformity and ensuring optimal lubrication and cooling effects during the grinding process.

[0040] Specifically, a drive block 50 is provided at the center of the bottom end face of the filter cylinder 40. The drive block 50 has an internal hexagonal drive hole 51. The drive assembly cooperates with the internal hexagonal drive hole 51 to make the filter cylinder 40 reciprocate.

[0041] Specifically, the drive assembly includes a hexagonal prism drive rod 24, which is rotatably mounted on the center of the bottom end face of the filter housing 20, and is adapted to the internal hexagonal drive hole 51.

[0042] Specifically, the bottom end face of the filter housing 20 is provided with multiple sets of support legs 22;

[0043] A drive servo motor 23 is provided at the center of the bottom end face of the filter housing 20, and the drive servo motor 23 is connected to the hexagonal prism drive rod 24 for transmission.

[0044] In this embodiment, when the filter cylinder 40 reciprocates, the drive servo motor 23 is turned on, driving the hexagonal prism drive rod 24 to rotate. Through the cooperation between the hexagonal prism drive rod 24 and the internal hexagonal drive hole 51, the filter cylinder 40 is driven to rotate.

[0045] Specifically, the filter cartridge 40 is provided with a rotating ring 42;

[0046] The filter housing 20 is provided with a rotating ring groove 27, and the cover plate 30 is provided with a limiting ring 32. The limiting ring 32 is matched with the rotating ring groove 27, and the limiting ring 32 is in contact with the rotating ring 42, so that the rotating ring 42 is rotatably disposed in the rotating ring groove 27.

[0047] In this embodiment, when the filter cartridge 40 is installed, the rotating ring 42 is placed in the rotating ring groove 27, and then the cover plate 30 is connected to the filter housing 20 by bolts, so that the limiting ring 32 contacts the rotating ring 42 and restricts the rotating ring 42 in the rotating ring groove 27.

[0048] Of course, the iron filings inside the filter cartridge 40 can be easily cleaned by bolting the cover plate 30 and the filter housing 20 together.

[0049] Specifically, the cover plate 30 is provided with a connecting pipe 31, which communicates with the inner cavity of the filter housing 20;

[0050] The filter housing 20 is provided with an installation pipe 28, which is connected to the inlet pipe 12 flange.

[0051] In this embodiment, when circulating and guiding the grinding fluid for cooling, the grinding fluid in the grinding area is introduced into the filter housing 20 through the connecting pipe 31.

[0052] Specifically, an annular baffle 21 is provided inside the filter housing 20, and multiple sets of baffle filter holes 211 are evenly provided on the annular baffle 21.

[0053] The filter housing 20 is further provided with a first cavity 25 and a second cavity 26, and the annular baffle 21 is disposed between the first cavity 25 and the second cavity 26.

[0054] Specifically, the outer wall of the filter cylinder 40 is provided with multiple sets of disturbance plates 43, and the disturbance plates 43 are in contact with but not connected to the inner wall of the annular baffle 21.

[0055] In this embodiment, the baffle filter holes 211 provided on the annular baffle 21 facilitate secondary filtration to improve the filtration quality. At the same time, during the rotation of the filter cylinder 40, the disturbance plate 43 is driven to rotate, which can disturb the iron filings at the baffle filter holes 211 and prevent clogging.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
