Description

Technical Field

[0001] The utility model relates to the technical field of cutting fluid production, in particular to a cutting fluid viscous material filtering device. Background Art

[0002] The role of cutting fluid is to improve the fineness of the workpiece and reduce the roughness of the surface, making the workpiece look more refined. The cutting fluid can also extend the service life of the tool and reduce friction between them.

[0003] Currently, when using cutting fluid to clean blades, due to its inherent viscosity, impurities on the blade surface are carried away during cleaning. Directly discharging this impurity-laden cutting fluid can easily lead to waste and environmental damage. Existing filtration methods rely primarily on centrifugal force to separate the cutting fluid from impurities. However, due to the high viscosity of the cutting fluid, the centrifugal force generated by the uniform rotation of the fluid is ineffective in separating impurities. Therefore, a device for filtering viscous cutting fluid is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a cutting fluid viscous material filtering device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cutting fluid viscous material filtering device comprises a base and a straight cylindrical filtering box fixedly mounted on the base.

[0007] In a preferred technical solution, the top of the filter box is provided with an inlet for the cutting fluid.

[0008] In a preferred technical solution, the filter box is fixedly mounted on the base, and a discharge port is provided on the side of the filter box. The discharge port is located at the bottom of the filter box.

[0009] The upper half of the interior of the filter box is provided with a pouring ring, and the lower half is provided with a fixing bracket.

[0010] In a preferred technical solution, the top surface of the pouring ring is designed as a feed slope, the bottom surface is designed as a blocking slope, and a through convergence channel is opened in the center of the pouring ring.

[0011] In a preferred technical solution, the diameter of the upper port of the convergence channel is larger than the diameter of the lower port thereof.

[0012] A vertical fixed shaft is inserted into the end of the fixed bracket. The lower end of the fixed shaft is connected to the disc, and the upper end is connected to the filter tank. The disc and the filter tank rotate coaxially.

[0013] In a preferred technical solution, the filter tank is a round belly structure, and the outer peripheral surface of the filter tank is provided with evenly distributed filter holes. The filter tank is located below the pouring ring and the top opening of the filter tank is aligned with the convergence channel above.

[0014] A motor is installed in the base, and a transmission shaft is provided at the output end of the motor. A swing arm is installed at the upper end of the transmission shaft. The transmission shaft is located at an eccentric position below the disc. A downward-facing fixed column is provided near the edge of the bottom surface of the disc. A waist-shaped groove is provided on the arm rod of the swing arm, and the fixed column is built into the waist-shaped groove and slides along it.

[0015] In a preferred technical solution, a fixed distance is maintained between the swing arm and the upper disc.

[0016] The beneficial effects of the utility model are:

[0017] The filtering device proposed in this solution solves the problem that the centrifugal force generated by uniform rotation cannot effectively separate impurities when using centrifugal force to separate viscous cutting fluid. The uniformly rotating disc is optimized to variable speed rotation. The centrifugal force generated during low-speed rotation is used to guide the cutting fluid and impurities to the bottom wall edge of the filter tank, while the centrifugal force generated during high-speed rotation is used to quickly throw the cutting fluid out of the filter tank, retaining the impurities inside the filter tank, thereby achieving the effect of filtering out impurities in the cutting fluid.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In this embodiment, refer to Figure 1-3 A device for filtering viscous cutting fluid includes a base 1 and a straight cylindrical filter box 2 fixedly mounted on the base 1. The top of the filter box 2 has an inlet 3 for the cutting fluid. The filter box 2 is fixedly mounted on the base 1 and has a discharge port 12 on its side. During cutting, a viscous mixture of cutting fluid and impurities falls into the filter box 2 through the inlet 3, which is designed to facilitate the introduction of the cutting fluid.

[0024] The upper half of the interior of the filter box 2 is provided with a pouring ring 4, and the lower half is provided with a fixing bracket 6.

[0025] like Figure 3 As shown, the top surface of the pouring ring 4 is designed as a feed slope 41, the bottom surface is designed as a blocking slope 43, and a through convergence channel 42 is opened in the center of the pouring ring 4. The design of the feed slope 41 facilitates the cutting fluid mixture to enter the convergence channel 42 along the direction of gravity flow.

[0026] The diameter of the upper port of the convergent channel 42 is larger than the diameter of the lower port. The purpose of this design is, on the one hand, to ensure that the cutting liquid mixture can accurately fall into the designated area; on the other hand, the design of the convergent pipe and the blocking slope 43 can effectively block the splashing liquid in the subsequent centrifugal filtration step.

[0027] A vertical fixed shaft 9 is inserted into the end of the fixed bracket 6. The lower end of the fixed shaft 9 is connected to the disc 10 and the upper end is connected to the filter tank 5. The lower disc 10 and the upper filter tank 5 rotate coaxially.

[0028] The filter tank 5 is a round structure with evenly distributed filter holes on its outer circumference. The filter tank 5 is located below the pouring ring 4 and the top opening of the filter tank 5 is aligned with the convergence channel 42 above. The cutting fluid mixture falling through the convergence channel 42 above falls directly into the filter tank 5 below.

[0029] A motor 7 is installed in the base 1, and a transmission shaft 13 is provided at the output end of the motor 7. A swing arm 8 is installed at the upper end of the transmission shaft 13. The transmission shaft 13 is located at an eccentric position below the disc 10, and a fixed distance is retained between the swing arm 8 and the upper disc 10.

[0030] A downward-facing fixed post 11 is located near the edge of the bottom surface of the disc 10. A waist-shaped notch 14 is defined in the arm of the swing arm 8, and the fixed post 11 is positioned within and slides along this notch. The rotation of the swing arm 8, driven by the drive shaft 13, does not directly affect the disc 10. Instead, it is achieved through the sliding fit between the swing arm 8 and the fixed post 11. The rotation of the swing arm 8 causes the fixed post 11 to slide along the waist-shaped notch 14, simultaneously causing the disc 10 and the filter canister 5 to rotate about the fixed shaft 9.

[0031] Since the transmission shaft 13 and the disc 10 are not coaxial and the fixing post 11 is also located at the edge of the bottom surface of the disc 10, the swing arm 8 will cause the rotation speed of the disc 10 to change during its rotation through the positional relationship between the waist-shaped notch 14 and the fixing post 11.

[0032] Combined with attachment Figure 2 To explain:

[0033] When the fixed post 11 gradually moves away from the transmission shaft 13 as the disc 10 rotates, that is, the distance between the fixed post 11 and the transmission shaft 13 increases, the rotation speed of the disc 10 increases, and therefore the centrifugal force increases. When the fixed post 11 gradually approaches the transmission shaft 13 as the disc 10 rotates, that is, the distance between the fixed post 11 and the transmission shaft 13 decreases, the rotation speed of the disc 10 decreases, and therefore the centrifugal force decreases.

[0034] Since the centrifugal force is in a periodic change process, the viscous mixture of cutting fluid containing impurities in the filter tank 5 will diverge to the inner wall around the filter tank 5 when the rotation speed is low. When the rotation speed gradually increases, the viscous material diverging to the surroundings will be quickly thrown out due to the sudden increase in centrifugal force, leaving only impurities in the tank.

[0035] The viscous cutting liquid is thrown out of the filter tank 5 by centrifugal force. The cutting liquid hits the blocking slope 43 or the inner wall of the filter box 2 and eventually slides to the bottom of the filter box 2 and is finally discharged outward through the discharge port 12.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
