Description

Technical Field

[0001] The utility model relates to a water retaining ring, in particular to a universal water retaining ring which reduces the intrusion of cutting fluid into a rotary oil cylinder. Background Art

[0002] Existing rotary cylinders often face the problem of cutting fluid entering the cylinder during use. This is especially true in machining environments. When a hollow rotary cylinder is used to drain cutting fluid, if the displacement is large or if a low-cost water trap is used, the cutting fluid can easily seep into the cylinder through the gaps. In this case, the cutting fluid mixes with the hydraulic oil inside the cylinder, causing it to deteriorate and affect normal operation. To avoid equipment damage and performance degradation, users are forced to frequently replace the hydraulic oil, increasing maintenance costs.

[0003] The current market solution primarily involves installing a cover on the rotary cylinder to block direct impact from the cutting fluid. However, this solution has limited effectiveness in practice, especially when customers opt for low-cost sheet metal water traps. The large volume of cutting fluid significantly reduces the protective effect of the cover, making it ineffective in preventing the cutting fluid from entering the cylinder. Therefore, existing technologies fail to fundamentally address this issue. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides a universal water retaining ring for reducing the entry of cutting fluid into the interior of the rotary cylinder. It can solve and improve the problem of water ingress into all current general structure rotary cylinders without replacing other inherently waterproof cylinders and without changing customer usage habits.

[0005] The utility model is realized by the following technical solutions: a universal water retaining ring for reducing the ingress of cutting fluid into the interior of a rotary oil cylinder, comprising:

[0006] A rotary oil cylinder, wherein a water collection box is installed on a working side of the rotary oil cylinder, and the water collection box has a water collection chamber;

[0007] A water retaining ring is installed on the assembly end of the rotary oil cylinder and is located in the water accumulation cavity of the water accumulation box.

[0008] As a preferred technical solution, the thickness of the water retaining ring is C, and the thickness of C is 5-8 mm.

[0009] As a preferred technical solution, the assembly end size of the rotary cylinder is E, the inner ring size of the water retaining ring is A, and the dimensional gap between A and E is between 0.05-0.1 mm.

[0010] As a preferred technical solution, a U-shaped groove is provided on one side of the inner ring of the water retaining ring, and the size of the U-shaped groove is D.

[0011] As a preferred technical solution, the width of the U-shaped groove D is 4-8 mm.

[0012] The beneficial effect of the utility model is that the utility model can significantly reduce the possibility of cutting fluid entering the cylinder by adding a water retaining ring to the rotary cylinder and utilizing the extremely small gap between the water retaining ring and the cylinder, thereby avoiding mixing of hydraulic oil and cutting fluid and preventing deterioration of the hydraulic oil.

[0013] Since the water retaining ring can effectively prevent the cutting fluid from entering the cylinder, it reduces the chance of hydraulic oil being contaminated, reduces the frequency of hydraulic oil replacement, extends the service life of the hydraulic oil, and reduces the maintenance cost of the equipment.

[0014] The utility model does not require customers to replace the rotary oil cylinder with waterproof function, nor does it require changes to existing usage habits and process flows. It only requires the simple installation of a water retaining ring to achieve a significant waterproof effect. It is suitable for all types of rotary oil cylinders with general structures and has good versatility.

[0015] The utility model has a simple structural design and utilizes the special shape and clearance fit of the water retaining ring to effectively block cutting fluid from entering the oil cylinder without increasing additional costs. It saves costs for the enterprise and reduces the pollution of the cutting fluid to the environment, thus having high economic and environmental benefits.

[0016] The utility model designs a D groove, which blocks and eventually discharges the cutting fluid accumulated in the gap during the rotation of the rotary cylinder, which not only reduces the accumulation of cutting fluid, but also further improves the waterproof effect, so that the cylinder can still maintain a good working condition during high-load operation.

[0022] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0023] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0024] like Figures 1-4 As shown, the utility model is a universal water retaining ring for reducing the entry of cutting fluid into the interior of a rotary oil cylinder, comprising a rotary oil cylinder 1, a water collection box 2 is installed on the working side of the rotary oil cylinder, and the water collection box 2 has a water collection chamber;

[0025] It also includes a water retaining ring 3, which is installed on the assembly end of the rotary oil cylinder and is located in the water accumulation cavity of the water accumulation box 2.

[0026] The thickness of the water retaining ring 3 is C, and the thickness of C is 5-8 mm, thereby reducing the impact force of the cutting fluid and reducing the amount of water inflow.

[0027] In this embodiment, the assembly end size of the rotary cylinder is E, the inner ring size of the water retaining ring is A, and the size gap between A and E is between 0.05-0.1mm. By matching the extremely small gap between the A size of the water retaining ring and the E size of the rotary cylinder, the assembly stability of the water retaining ring is increased while preventing leakage, thereby effectively ensuring the sealing.

[0028] Among them, a U-shaped groove is provided on one side of the inner ring of the water retaining ring. The size of the U-shaped groove is D. In this embodiment, the width of the U-shaped groove D is 4-8mm, and the best is 6mm. By utilizing the rotation characteristics of the rotary cylinder itself, the cutting fluid enriched in the gap between A and E as the cylinder rotates is blocked and finally discharged.

[0029] The utility model adds a water retaining ring to the rotary oil cylinder and utilizes the extremely small gap between the water retaining ring and the oil cylinder to significantly reduce the possibility of cutting fluid entering the oil cylinder, avoids the mixing of hydraulic oil and cutting fluid, and thus prevents the hydraulic oil from deteriorating.

[0030] Since the water retaining ring can effectively prevent the cutting fluid from entering the cylinder, it reduces the chance of hydraulic oil being contaminated, reduces the frequency of hydraulic oil replacement, extends the service life of the hydraulic oil, and reduces the maintenance cost of the equipment.

[0031] The utility model does not require customers to replace the rotary oil cylinder with waterproof function, nor does it require changes to existing usage habits and process flows. It only requires the simple installation of a water retaining ring to achieve a significant waterproof effect. It is suitable for all types of rotary oil cylinders with general structures and has good versatility.

[0032] The utility model has a simple structural design and utilizes the special shape and clearance fit of the water retaining ring to effectively block cutting fluid from entering the oil cylinder without increasing additional costs. It saves costs for the enterprise and reduces the pollution of the cutting fluid to the environment, thus having high economic and environmental benefits.

[0033] The utility model designs a D groove, which blocks and eventually discharges the cutting fluid accumulated in the gap during the rotation of the rotary cylinder, which not only reduces the accumulation of cutting fluid, but also further improves the waterproof effect, so that the cylinder can still maintain a good working condition during high-load operation.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
