Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a circulating water filtration and recovery mechanism for a slant rail CNC lathe. Background Technology

[0002] During CNC lathe machining, impurities such as metal shavings, dust, and oil can mix into the cooling water. If the water is directly recycled, these impurities may scratch the workpiece surface, clog the tool cooling channels, and even accelerate tool wear. The filtration and recovery system removes impurities through filters, magnetic separation, and sedimentation, ensuring the cleanliness of the cooling lubricant and maintaining machining accuracy and surface quality.

[0003] Patent CN221984597U discloses a slant-rail type CNC metal cutting machine tool, relating to the field of machining equipment technology. It includes a machine tool body with a first limiting groove on the top. In this invention, a slant-rail groove is provided at the bottom of the inner wall of the machine tool body, and a third limiting groove is provided at the bottom of the inner wall of the machine tool body. A fixed box is installed inside the third limiting groove, and a fourth limiting groove is provided at the top of the fixed box. A filter plate is installed on one side of the inner wall of the fixed box, and a magnet is installed on the top of the filter plate. A discharge cover and a discharge pipe are installed on one side of the fixed box, and a control valve is installed on the outer surface of the discharge pipe. When chips and coolant fall into the slant-rail groove, they enter the interior of the fixed box. Through the action of the filter plate and the magnet, the chips and coolant are separated and discharged through the discharge port and discharge pipe, making the collection of chips and coolant more convenient.

[0004] The aforementioned patent has insufficient coolant recycling capacity and weak filtration accuracy and purification effect during use. It only separates chips through filter plates and magnetic blocks, making it difficult to filter out fine particles, oil stains or other impurities in the coolant. The purity of the separated coolant is low, and direct discharge will cause pollution. Recycling may affect the machining accuracy. Based on this, a circulating water filtration and recovery mechanism for a slant rail CNC lathe is proposed for improvement. Utility Model Content

The lathe body includes a filtration mechanism for facilitating coolant circulation and a snap-fit ​​mechanism for easy maintenance. A primary filter groove is provided on the front side of the inner wall of the lathe body. A fixing plate is fixedly installed at the other end of the primary filter groove. A conical groove is provided on the bottom wall of the primary filter groove. A filter chamber is provided on the bottom wall of the conical groove.

[0007] As a preferred embodiment, the primary filter tank has a support groove at one end, and a chip collection box is slidably connected to the inner wall of the support groove, with the top of the chip collection box slightly lower than the top of the filter plate.

[0008] As a preferred embodiment, an arc-shaped protective plate is connected between one side of the fixed plate and the inner wall of the primary filter tank, and the scraper is slidably connected to the surface of the arc-shaped protective plate.

[0009] As a preferred embodiment, a circulation pump is fixedly installed on the inner wall of the liquid storage chamber, a delivery pipe is fixedly connected to the output end of the circulation pump, a flexible tube is fixedly connected to the top end of the delivery pipe, and one end of the flexible tube extends into the interior of the lathe body.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model uses a filter plate to intercept large-sized debris, a filter cloth plate to remove fine particles, and an activated carbon plate to adsorb oil and odors. This progressive purification process ensures the cleanliness of the coolant, achieving multi-stage filtration of the coolant. The coolant then flows into the storage chamber and is reused by the circulation pump, realizing the recycling of the coolant and reducing production costs.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a circulating water filtration and recovery mechanism for a slant rail CNC lathe, including a lathe body 1, a box door 4 slidably connected to the front side of the lathe body 1, an observation window 41 in the middle of the box door 4, a clamp 2 on one side of the inner wall of the lathe body 1, and a cutting assembly 3 on the other side of the inner wall of the lathe body 1. The lathe body 1 includes a filtration mechanism for facilitating coolant circulation and a snap-fit ​​mechanism for easy maintenance. A primary filter trough 5 is provided on the front side of the inner wall of the lathe body 1. A fixing plate 512 is fixedly installed at the other end of the primary filter trough 5. A conical groove 51 is provided on the bottom wall of the primary filter trough 5. A filter chamber 52 is provided on the bottom wall of the conical groove 51. A filter cloth plate 7 is provided on the upper part of the inner wall of the filter chamber 52. An activated carbon plate 8 is provided on the lower part of the inner wall of the filter chamber 52. An infusion trough 53 is provided on the rear side of the inner wall of the filter chamber 52. A liquid storage chamber 54 is provided on the rear side of the lathe body 1. The filter chamber 52 is connected to the liquid storage chamber 54 through the infusion trough 53. A filter plate 56 is fixedly installed on the inner wall of the primary filter tank 5. A motor 58 is fixedly installed at the other end of the primary filter tank 5. The output shaft of the motor 58 passes through the side wall of the fixed plate 512 and is fixedly sleeved with a lead screw 59. A scraper 510 is threadedly connected to the surface of the lead screw 59. The bottom end of the scraper 510 contacts the top end of the filter plate 56. The primary filter tank 5 has a support groove 55 at one end, and a chip collection box 57 is slidably connected to the inner wall of the support groove 55. The top of the chip collection box 57 is slightly lower than the top of the filter plate 56. An arc-shaped protective plate 511 is connected between one side of the fixed plate 512 and the inner wall of the primary filter tank 5, and the scraper 510 is slidably connected to the surface of the arc-shaped protective plate 511. A circulation pump 9 is fixedly installed on the inner wall of the liquid storage chamber 54. A delivery pipe 91 is fixedly connected to the output end of the circulation pump 9. A flexible tube 92 is fixedly connected to the top end of the delivery pipe 91. One end of the flexible tube 92 extends into the interior of the lathe body 1.

[0019] Specifically, the mixture first comes into contact with the filter plate 56 in the primary filter tank 5. The filter plate 56 intercepts larger cutting chips, achieving preliminary filtration. The pre-filtered coolant flows into the filter chamber 52 through the conical groove 51. The filter chamber 52 is equipped with a filter cloth plate 7 and an activated carbon plate 8 in sequence. The upper filter cloth plate 7 further filters out fine particulate impurities in the coolant, while the lower activated carbon plate 8 adsorbs oil, odors, etc. in the coolant, achieving deep purification. The purified coolant flows into the storage chamber 54 through the delivery tank 53. The circulation pump 9 is started to deliver the purified coolant to the hose 92 through the delivery pipe 91. The hose 92 then delivers it back to the processing area for reuse as coolant, thus completing the circulation.

[0020] When it is necessary to clean the debris accumulated on the filter plate 56, the motor 58 is started, and its output shaft drives the lead screw 59 to rotate, so that the scraper 510 pushes the debris accumulated on the filter plate 56 into the support groove 55 at one end of the primary filter tank 5, and finally falls into the debris collection box 57. The debris collection box 57 can be slid out for cleaning, which is convenient for maintenance. During the movement of the scraper 510, the arc-shaped protective plate 511 not only guides the sliding trajectory of the scraper 510, but also prevents the debris from contacting the lead screw 59, avoiding thread jamming or damage, and ensuring the stable operation of the lead screw 59. This design uses filter plate 56 to intercept large debris, filter cloth plate 7 to remove fine particles, and activated carbon plate 8 to absorb oil and odors. This progressive purification process ensures the cleanliness of the coolant and achieves multi-stage filtration of the coolant. The coolant then flows into the storage chamber 54 and is reused by the circulation pump 9, realizing the recycling of the coolant and reducing production costs. The motor 58 drives the lead screw 59 to drive the scraper 510 to automatically push the debris on the filter plate 56 into the debris storage box 57, eliminating the need for frequent manual cleaning and reducing the workload of operators. The debris storage box 57 also achieves centralized collection of debris, preventing debris from scattering inside the equipment and becoming difficult to clean.

[0021] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the inner wall of the filter chamber 52 is provided with a plurality of C-shaped plates 6, the filter cloth plate 7 is slidably connected to the inner wall of the C-shaped plates 6 symmetrically arranged on the upper part of the inner wall of the filter chamber 52, and the activated carbon plate 8 is slidably connected to the inner wall of the C-shaped plates 6 symmetrically arranged on the lower part of the inner wall of the filter chamber 52. A groove 61 is provided on the upper part of the inner wall of the C-shaped plate 6. A locking rod 62 is slidably connected to the inner wall of the groove 61. A spring 63 is movably connected to the top of the locking rod 62. The top of the spring 63 is fixedly connected to the inner wall of the groove 61. The filter cloth plate 7 and the activated carbon plate 8 are respectively provided with symmetrical slots 64 at their top ends, and the bottom end of the clamping rod 62 is fitted into the inner wall of the slot 64.

[0022] Specifically, the C-shaped plate 6 provides sliding tracks for the filter cloth plate 7 and the activated carbon plate 8. When the filter cloth plate 7 and the activated carbon plate 8 slide into the designated position, the locking rod 62 will be embedded into the corresponding slot 64 at the top of the plate under the elastic force of the spring 63, forming a stable lock. When it is necessary to replace or clean these two filter components, the operator can directly pull them along the inner wall of the C-shaped plate 6 without disassembling complex connecting parts, which can quickly complete the replacement of components, reduce equipment downtime, reduce assembly difficulty, and facilitate later maintenance.
