Description

Technical Field

[0001] This utility model relates to the field of gear manufacturing technology, specifically to a gear processing cutting fluid circulation and purification device. Background Technology

[0002] Gear machining is a key production link for high-precision transmission parts in mechanical manufacturing. It requires multiple processes to achieve the requirements for tooth shape, size and precision. The entire machining process must strictly follow the process specifications and use precision instruments such as gear measuring centers to carry out full-process quality inspection to ensure that the produced gears meet the stringent requirements of modern industry for high-precision transmission systems.

[0003] Gear machining cutting fluid is an auxiliary liquid specifically used in gear machining processes. It is mainly used for cooling and lubrication. During machining, the cutting fluid can remove a large amount of cutting heat, reduce the temperature of the tool and workpiece, thereby extending tool life and reducing workpiece deformation. At the same time, it can also form a lubricating film on the tool and workpiece surfaces, reducing friction, reducing cutting force, and improving machining efficiency and surface quality.

[0004] Filtration and recovery of cutting fluid can effectively reduce production costs. However, metal debris in cutting fluid has sharp edges that can easily wear down the filter unit. After long-term operation, the filter screen of traditional filter units will become clogged or damaged due to the accumulation and wear of metal debris in the cutting fluid. This not only reduces filtration efficiency but may also affect the quality of cutting fluid recovery. Therefore, a gear processing cutting fluid circulation and purification device is proposed to address the above problems. Utility Model Content

[0027] 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.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-8 This utility model provides a technical solution:

[0030] A gear processing cutting fluid circulation and purification device includes a purification filter box 1 and a servo motor 2. The servo motor 2 is fixedly installed on one side of the purification filter box 1 by bolts. A magnetic roller 3 is inserted into one end of the main shaft of the servo motor 2. An inclined block 4 is fixedly connected to the inside of the purification filter box 1. A filter assembly 5 is fixedly connected to the inside of the purification filter box 1. A dust scraper 6 is glued and fixed to the upper end of the filter assembly 5. The filter assembly 5 includes a support frame 51. An elastic rubber sheet 52 is glued and fixed to the inside of the support frame 51. A filter plate 53 is glued and fixed to the inside of the elastic rubber sheet 52. A filter hole 54 is opened in the inside of the filter plate 53. A support plate 55 is fixedly connected to the bottom end of the support frame 51 by bolts. A stopper rod assembly 56 is fixedly connected to the upper end of the support plate 55. A notch 57 is opened on one side of the support plate 55. The stopper rod assembly 56 includes a rubber column 561. A groove 562 is opened on the outer side of the rubber column 561. An inner cavity 563 is opened on the inner side of the rubber column 561. A return spring 564 is fixedly connected to the inner side of the inner cavity 563.

[0031] As a further implementation of this solution, the outer side of the dust scraper 6 is attached to the outer side of the magnetic roller 3, and the side of the dust scraper 6 that is attached to the magnetic roller 3 is arc-shaped. The magnetic roller 3 is positioned above the filter assembly 5 and above the inclined block 4. The arc-shaped design of the side of the dust scraper 6 that is attached to the magnetic roller 3 allows the dust scraper 6 to better scrape off the iron filings attached to the surface of the magnetic roller 3 without damaging the magnetic roller 3. The magnetic roller 3 being positioned above the filter assembly 5 can disturb the cutting fluid above the filter assembly 5 when it rotates.

[0032] As a further implementation of this solution, the included angle between the rubber column 561 and the support plate 55 is 90°. The central axis of the return spring 564 and the central axis of the rubber column 561 are on the same straight line. The rubber column 561 is fixedly connected to both the upper and lower ends of the return spring 564. When the rubber column 561 is subjected to force, it can receive better support from the support plate 55. The setting of the return spring 564 makes the rubber column 561 have better toughness to recover its own deformation.

[0033] As a further implementation of this solution, multiple grooves 562 are provided, and the multiple grooves 562 are distributed in a ring array in the rubber column 561. The upper end of the rubber column 561 is arc-shaped. The opening height of the grooves 562 is one-third of the height of the rubber column 561. Multiple grooves 562 are provided to accelerate the flow efficiency of cutting fluid. The arc-shaped setting of the upper end of the rubber column 561 can effectively allow iron filings falling on it to slide off, and prevent iron filings from getting stuck in the filter hole 54.

[0034] As a further implementation of this solution, the vertical projection of the support frame 51 is "U" shaped, the filter plate 53 is parallel to the support frame 51, the length of the filter plate 53 is four-fifths of the length of the support frame 51, and the width of the filter plate 53 is four-fifths of the width of the support frame 51. This arrangement ensures that the filter plate 53 can avoid contact with the support frame 51 and be damaged when it moves up and down.

[0035] As a further implementation of this scheme, the diameter of the filter hole 54 is equal to the diameter of the rubber column 561, and the positions of the filter hole 54 and the rubber column 561 correspond one-to-one. Part of the rubber column 561 is inserted into the filter hole 54. Two slots 57 are provided, and the two slots 57 are symmetrically distributed. The slots 57 are rectangular in shape. The groove 562 provided on the rubber column 561 is located below the filter plate 53. The rubber column 561 and the filter hole 54 form a seal, so the cutting fluid cannot flow through the filter hole 54 to the bottom of the inner side of the purification filter box 1. Only when the groove 562 is located above the filter plate 53 can the cutting fluid flow from above the filter plate 53 to the support plate 55 through the groove 562, and fall into the bottom of the inner side of the purification filter box 1 through the slot 57 provided in the support plate 55. In this way, the iron filings in the cutting fluid are first removed by the magnetic roller 3 before being collected by the filter box 1.

[0036] Working process: When the device is in use, the cleaning filter box 1 is used to collect the cutting fluid after gear machining. When the cutting fluid enters the cleaning filter box 1 and falls above the filter assembly 5, the plug rod assembly 56 is inserted into the filter hole 54, and the groove 562 on the rubber column 561 is located below the filter plate 53. A seal is formed between the rubber column 561 and the filter hole 54, preventing the cutting fluid from flowing through the filter hole 54 to the bottom of the cleaning filter box 1. The cutting fluid accumulates above the filter plate 53. The spindle of the servo motor 2 rotates, driving the magnetic roller 3 to rotate and cut the cutting fluid. Iron filings in the liquid are adsorbed. As the magnetic roller 3 rotates at a certain angle, the iron filings on the surface of the magnetic roller 3 are scraped off by the dust scraper 6 and fall onto the inclined block 4. As the inclined block 4 slides down the inclined surface, it falls into the collection box set next to the purification filter box 1. The rotation of the magnetic roller 3 can disturb the cutting fluid accumulated above the filter plate 53, thereby better moving the iron filings in the cutting fluid and finally being adsorbed by the magnetic roller 3. When the cutting fluid accumulates to a certain amount above the filter plate 53, it will exert downward pressure on the filter plate 53, causing the filter plate 53 to drive the fixedly connected elastic rubber 52 to deform. The change causes the piston rod assembly 56 to move downwards, thereby altering the relative position of the piston rod assembly 56 and the filter hole 54. At this time, the groove 562 on the rubber rod 561 is located above the filter plate 53. The cutting fluid can flow from above the filter plate 53 to the support plate 55 through the groove 562, and fall into the bottom of the purification filter box 1 through the slot 57 in the support plate 55, where it is collected and finally discharged from the outlet at the bottom of the purification filter box 1. When the cutting fluid no longer accumulates above the filter plate 53, the elastic force generated by the recovery deformation of the elastic rubber 52 will drive the piston rod assembly 56 to move downwards. During the reset process, the rubber column 561 remains inserted in the filter hole 54. The arc-shaped design at the upper end of the rubber column 561 allows iron filings that fall onto it to slide off effectively, preventing them from getting stuck in the filter hole 54. At the same time, the groove 562 in the rubber column 561 gives it better deformation capability, allowing it to adapt to the shaking caused by changes in the position of the filter plate 53. The inner cavity 563 gives the rubber column 561 better recovery deformation capability, enabling it to guide and reset the displacement of the filter plate 53.
