Description

Technical Field

[0001] The invention relates to a cutting fluid filtering device for a machining lathe and a working method thereof, belonging to the technical field of machine tool processing. Background Art

[0002] Machining lathe cutting is a processing method that removes workpiece material through the relative movement between the rotating workpiece and the cutting tool of the lathe. The cutting process removes excess material from the workpiece surface through the contact between the tool and the workpiece surface to form the required size and shape. Cutting fluid is required in the cutting process. The cutting fluid can be recycled and reused after use, so a cutting fluid circulation filtration device is needed.

Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] A cutting fluid filter device for a machining lathe includes a filter device body. The filter device body adopts the filter device described in the background technology, that is, it includes an outer barrel 100, an inner barrel 110, a collecting barrel 120, a ring 234, a gear 235, a first motor 261, a gear ring 270, a connecting pipe 236 and a filter assembly 200; the filter assembly 200 includes a transverse plate 210, a magnet 220, a screw 230, an L-shaped ring plate 231, a support plate 232, a limit rod 233 and a second motor 260, which is the prior art, so it is not repeated here. The transverse plate 210 of the filter device body (i.e., the fixed plate in CN217962942U, since the transverse plate of this application is non-fixed and non-detachable to the outer barrel, this application renames it as a transverse plate) is detachably and fixedly connected to the outer barrel 100 of the filter device body through a disassembly mechanism 300. The upper surface of the outer barrel 100 of the present invention is higher than the upper surface of the inner barrel 110 to prevent the cross plate 210 from rubbing against the inner barrel 110 after installation, thereby preventing the components from being worn.

[0029] The disassembly and assembly mechanism 300 includes two symmetrically arranged disassembly and assembly units, each of which includes a fixed frame 310, a positioning block 320, a pull rod 321, a positioning rod 331 and a first spring 340; the fixed frame 310 is fixed to the outer wall of the outer barrel 100, and the inner wall of the fixed frame 310 is slidably connected to the positioning block 320 by means of a slider 370 slidably arranged in a slide groove 371, the outer side of the positioning block 320 is fixedly connected to one end of a horizontally arranged pull rod 321, and the other end of the pull rod 321 slides out of the outer side of the fixed frame 310, and the outer side of the pull rod 321 is sleeved with a first spring 340, one end of the first spring 340 abuts against the positioning block 320, and the other end of the first spring 340 abuts against the corresponding inner wall of the fixed frame 310; the two ends of the cross plate 210 are respectively fixedly connected to the upper ends of the corresponding vertically arranged positioning rods 331, and the lower ends of the positioning rods 331 are respectively connected to the corresponding positioning blocks 320 for limiting position.

[0030] A slot is formed on the side wall of each positioning rod 331 adjacent to the positioning block 320 , and the positioning block 320 is matched and inserted into the corresponding slot.

[0031] A wedge-shaped surface is provided on one side of the positioning block 320 adjacent to the positioning rod 331 to facilitate quick insertion of the positioning rod 331 .

[0032] A roller 330 is rotatably provided at the lower end of each positioning rod 331. The roller 330 is matched with the corresponding wedge surface to convert sliding friction into rolling friction, thereby improving the convenience of use and allowing the cross plate to be quickly fixed.

[0033] The inner bottom surface of the fixed frame 310 is connected to the horizontally arranged movable plate 350 through a plurality of second springs 360 arranged in an array. The movable plate 350 is arranged below the positioning block 320 and the positioning rod 331 to facilitate the upward popping of the positioning rod 331 during disassembly, thereby facilitating the disassembly of the horizontal plate.

[0034] The outer wall of the support plate 232 of the filter device body is fixedly connected to the horizontal rods of multiple L-shaped scraper rods 240 evenly distributed along its circumference. The vertical rods of each scraper rod 240 are fitted with the inner wall of the inner barrel 110 of the filter device body to clean the cutting fluid on the inner wall of the inner barrel 110 to prevent impurities from remaining on the inner wall of the inner barrel.

[0035] The filter screen 250 of the filter device body is a cone-shaped structure to prevent the filter screen from being blocked.

[0036] The outer edge of the filter screen 250 is provided with an annular groove along its circumference, so that the filtered material can be collected in the annular groove along its surface. The storage barrel 120 of the filter device body is provided with an opening fan, which is not shown in the drawings, and the filtered material in the annular groove is cleaned by opening the fan.

[0037] A working method of a cutting fluid filtering device for a machining lathe of the present invention comprises the following steps:

[0038] S1: Align the two positioning rods 331 with the wedge-shaped surfaces of the corresponding positioning blocks 320 and insert them into the corresponding fixing frames 310. The positioning blocks 320 are inserted into the slots of the corresponding positioning rods 331 under the action of the first springs 340. The positioning rods 331 press the moving plate 350 downward to compress the second springs 360, thereby completing the fixing of the transverse plate 210.

[0039] S2: The cutting fluid to be circulated and filtered is introduced into the inner barrel 110 for filtration. During the filtration process, the scraper rod 240 cleans the inner wall of the inner barrel 110;

[0040] S3: After the filtration is completed, the two pull rods 321 are pulled outward to drive the two positioning blocks 320 to move to separate from the corresponding positioning rods 331;
