Description

Technical Field

[0001] This application relates to the field of CNC lathe technology, and in particular to a CNC lathe chip anti-splash device. Background Technology

[0002] During CNC lathe machining operations, the cutting of the workpiece by the cutting tool generates a large amount of hot, sharp iron filings. These filings usually fly everywhere with the cutting action, which can not only easily cut the operator, but also damage the equipment or instruments around the machine tool, posing a significant threat to operational safety.

[0003] Although some existing CNC lathes are equipped with protective covers, these covers can only block some of the flying iron filings and cannot clean the iron filings inside the machine tool. The flying iron filings will scatter to various areas inside the CNC machine tool body. If they are not cleaned in time, the accumulation of iron filings will affect the accuracy of the moving parts of the machine tool, leading to increased machining errors and shortening the service life of the machine tool. When cleaning manually, operators need to go deep into the machine tool to wipe it, which is not only time-consuming and laborious, but also carries the risk of being scratched by residual iron filings.

[0004] Therefore, we provide a chip anti-splash device for CNC lathes. Utility Model Content

[0005] This application discloses a chip anti-splash device for CNC lathes, which aims to solve the technical problems of CNC lathes.

[0006] To achieve the above objectives, this application adopts the following technical solution: A CNC lathe chip anti-splash device includes a CNC machine tool body, a movable door panel is provided on the front of the CNC machine tool body, the movable door panel is slidably disposed on the surface of the CNC machine tool body, and a chip cleaning component is provided inside the CNC machine tool body; The metal chip cleaning assembly includes a first guide slide and a second guide slide. The first guide slide and the second guide slide are both fixedly connected between the left and right inner sidewalls of the CNC machine tool body. The surfaces of the first guide slide and the second guide slide are slidably fitted with movable sleeves. The bottom ends of the two movable sleeves are fixedly connected with extension frames. The bottom ends of the two extension frames are fixedly connected with strip-shaped movable shells. The surface of the strip-shaped movable shells is fixedly embedded with a plurality of air nozzles, and the bottom of the strip-shaped movable shells is fixedly connected with strip-shaped brushes. The strip-shaped brushes overlap with the inner bottom wall of the CNC machine tool body.

[0007] By adopting the above technical solution, the movable door panel can slide to close the front of the CNC machine tool body, preventing iron filings from flying outward and avoiding iron filings from scratching operators or damaging surrounding equipment.

[0008] Optionally, the inner wall of the CNC machine tool body is provided with a mounting groove, and an air pump is fixedly connected to the inner wall of the mounting groove. A corrugated air guide pipe is fixedly connected to the output end of the air pump, and the end of the corrugated air guide pipe away from the air pump is fixedly connected to the air inlet end of the strip-shaped moving shell.

[0009] By adopting the above technical solution, the iron filings cleaning component can drive the sliding sleeve through the L-shaped connecting block during the closing and opening of the movable door panel, thereby causing the strip-shaped movable shell to move synchronously. During the movement, the strip brush can automatically clean the iron filings on the inner bottom wall of the machine tool, eliminating the need for manual wiping and centrally processing the internal iron filings.

[0010] Optionally, a limit stop is fixedly connected to the inner wall of the CNC machine tool body, and a touch switch is fixedly connected to the surface of the limit stop, the position of which corresponds to the strip-shaped moving shell.

[0011] By adopting the above technical solution, the touch switch is set so that it will separate from the movable door panel when it is opened, thereby automatically starting the air pump. Air is supplied to the strip-shaped movable shell through the corrugated air guide pipe. The air jet nozzle is tilted downward to blow away the stubborn iron filings, forming a double cleaning with the strip brush and improving cleaning efficiency.

[0012] Optionally, a waste collection trough is provided on the left side of the CNC machine tool body, and a waste inlet hole is provided on the left inner wall of the CNC machine tool body. The position of the waste inlet hole corresponds to the waste collection trough. A discharge cover plate is rotatably connected to the left side of the CNC machine tool body via a hinge. The position of the discharge cover plate corresponds to the waste collection trough. The left end of the waste inlet hole extends into the interior of the waste collection trough, and the length of the waste inlet hole matches the width of the front and rear inner walls of the CNC machine tool body.

[0013] By adopting the above technical solution, the waste collection trough is set up so that the cleaned iron filings can directly enter the waste collection trough through the waste inlet hole, realizing the directional collection of iron filings. The waste collection trough is equipped with a rotatable discharge cover plate, so when cleaning iron filings in the future, you only need to open the cover plate. The operation is convenient and can prevent the collected iron filings from scattering again.

[0014] Optionally, several of the jet nozzles are evenly distributed in a linear array on the surface of the strip-shaped movable shell, and the jet nozzles have a downward-sloping shape.

[0015] By adopting the above technical solution, several downward-sloping air nozzles are set on the surface of the strip-shaped moving shell, and air is supplied to the strip-shaped moving shell through the corrugated air guide pipe. The downward-sloping air nozzles can help blow away stubborn iron filings, forming a double cleaning with the strip brush.

[0016] Optionally, a connecting rod is fixedly connected between the two movable sleeves, and an L-shaped connecting block is fixedly connected to the back of the movable door panel. The end of the L-shaped connecting block away from the movable door panel is fixedly connected to the surface of the movable sleeve. A limit guide hole is opened on the top front of the CNC machine tool body. The position of the limit guide hole corresponds to the L-shaped connecting block, and the L-shaped connecting block is slidably connected to the inner wall of the limit guide hole.

[0017] By adopting the above technical solution, the limiting guide hole can be used to guide and limit the strip-shaped moving shell by using the L-shaped connecting block and the limiting guide hole, thereby improving the stability and smoothness of the iron filings cleaning component during operation.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. The sliding door panel can close the front of the CNC machine tool body, preventing iron filings from splashing outwards and avoiding injury to operators or damage to surrounding equipment. By incorporating an iron filings cleaning component, the L-shaped connecting block drives the sliding sleeve during the opening and closing of the sliding door panel, causing the strip-shaped moving shell to move synchronously. During this movement, the strip brush automatically cleans the iron filings from the inner bottom wall of the machine tool, eliminating the need for manual wiping. This centralized treatment of internal iron filings reduces their disorderly scattering inside the machine tool, further minimizing the risk of iron filings splashing into the operating area.

[0019] 2. When the sliding door panel is opened, it separates from the touch switch, automatically activating the air pump. Air is supplied to the strip-shaped sliding housing through a corrugated air duct. The downward-tilted air nozzle helps to blow away stubborn iron filings, creating a dual cleaning process with the strip brush, improving cleaning efficiency. The cleaned iron filings can directly enter the waste collection trough through the waste inlet hole, achieving directional collection. The waste collection trough is equipped with a rotatable discharge cover; subsequent cleaning of iron filings only requires opening the cover, making operation convenient and preventing secondary spillage of the collected iron filings.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This embodiment discloses a chip anti-splash device for CNC lathes. (Refer to...) Figures 1-4 The system includes a CNC machine tool body 1, and a movable door panel 2 is provided on the front of the CNC machine tool body 1. The movable door panel 2 is directly slidably mounted on the surface of the CNC machine tool body 1 and can be opened and closed along the sliding trajectory on the front of the CNC machine tool body 1, thereby closing or opening the front operating area of ​​the CNC machine tool body 1.

[0027] A chip cleaning assembly 4 is installed inside the CNC machine tool body 1, penetrating the left and right inner sidewalls of the CNC machine tool body 1. The first guide slide rod 401 and the second guide slide rod 402 of the chip cleaning assembly 4 are arranged in parallel, with both ends fixedly connected between the left and right inner sidewalls of the CNC machine tool body 1, forming a stable lateral support structure. Movable sleeves 403 are slidably fitted onto the surfaces of the first guide slide rod 401 and the second guide slide rod 402, respectively. The two movable sleeves 403 are at the same horizontal height and can slide synchronously along the length of their respective guide slide rods.

[0028] Both movable sleeves 403 are fixedly connected to their bottom ends with extension frames 404, which extend vertically downwards. Their bottom ends are jointly fixedly connected to a strip-shaped movable shell 405. The strip-shaped movable shell 405 is elongated and its width matches the front and rear inner walls of the CNC machine tool body 1. It can slide horizontally above the inner bottom wall of the CNC machine tool body 1 as the movable sleeves 403 slide. Several air nozzles 406 are fixedly embedded on the surface of the strip-shaped movable shell 405. All air nozzles 406 are evenly distributed in a linear array, and the air outlets of the air nozzles 406 are all angled downwards to ensure that the ejected airflow directly acts on the inner bottom wall of the CNC machine tool body 1. Simultaneously, a strip-shaped brush 407 is fixedly connected to the bottom of the strip-shaped movable shell 405. The bristles of the strip-shaped brush 407 directly overlap the inner bottom wall of the CNC machine tool body 1, allowing it to wipe away iron filings on the inner bottom wall as the strip-shaped movable shell 405 moves.

[0029] An installation groove is provided on the inner side wall of the CNC machine tool body 1. An air pump 408 is fixedly connected to the inner wall of the installation groove. A corrugated air guide pipe 409 is fixedly connected to the output end of the air pump 408. The corrugated air guide pipe 409 is telescopic. Its end away from the air pump 408 is fixedly connected to the air inlet end of the strip-shaped moving shell 405. Its length can be flexibly adjusted as the strip-shaped moving shell 405 moves, so as to continuously deliver airflow to the strip-shaped moving shell 405.

[0030] A limit stop 410 is fixedly connected to the inner wall of the CNC machine tool body 1. The limit stop 410 is located on one side of the chip cleaning assembly 4, and a touch switch 411 is fixedly connected to its surface. The position of the touch switch 411 corresponds to the strip-shaped moving shell 405. When the strip-shaped moving shell 405 slides to a position close to the limit stop 410, it can contact the touch switch 411 and trigger the switch action.

[0031] A waste collection trough 5 is provided on the left side of the CNC machine tool body 1. The waste collection trough 5 is recessed and used to store the cleaned iron filings. On the left inner wall of the CNC machine tool body 1, corresponding to the position of the waste collection trough 5, a waste inlet hole 6 is provided. The left end of the waste inlet hole 6 extends into the interior of the waste collection trough 5, and the right end communicates with the interior of the CNC machine tool body 1. The length of the waste inlet hole 6 matches the width of the front and rear inner walls of the CNC machine tool body 1, ensuring that the iron filings can fully enter the waste collection trough 5. In addition, a discharge cover plate 7 is rotatably connected to the left side of the CNC machine tool body 1 via a hinge. The discharge cover plate 7 covers the opening of the waste collection trough 5 and can be opened and closed by rotation to facilitate subsequent cleaning of the iron filings in the waste collection trough 5.

[0032] A connecting rod 412 is fixedly connected between the two movable sleeves 403. The connecting rod 412 is arranged laterally to keep the two movable sleeves 403 in a synchronous sliding state and avoid misalignment. On the back of the movable door panel 2, an L-shaped connecting block 413 is fixedly connected. One end of the L-shaped connecting block 413 is fixed to the movable door panel 2, and the other end extends into the interior of the CNC machine tool body 1 and is fixedly connected to the surface of one of the movable sleeves 403. At the same time, a limiting guide hole 414 is opened on the top front of the CNC machine tool body 1. The position of the limiting guide hole 414 corresponds to the L-shaped connecting block 413. The L-shaped connecting block 413 passes through the limiting guide hole 414 and is slidably connected to the inner wall of the limiting guide hole 414. The limiting guide hole 414 provides trajectory constraints for the movement of the L-shaped connecting block 413, ensuring the stability when the movable door panel 2 and the movable sleeves 403 are linked.

[0033] The working principle of the anti-splatter device for CNC lathe chips according to an embodiment of this application is as follows: During normal operation of the CNC lathe, the movable door plate 2 is in a closed state. At this time, the movable door plate 2 drives the movable sleeve 403 to slide to a position close to the limit stop 410 through the L-shaped connecting block 413. The strip-shaped movable shell 405 contacts the touch switch 411. When the touch switch 411 is turned on, the air pump 408 is in a power-off state to avoid airflow interfering with the lathe operation. At the same time, the closed movable door plate 2 prevents the chips generated inside the CNC machine tool body 1 from splashing outward, and the chips naturally fall to the inner bottom wall of the CNC machine tool body 1. When the lathe operation is completed and the chips need to be cleaned, the operator slides open the movable door plate 2. The movable door plate 2 drives the L-shaped connecting block 413 to slide along the limit guide hole 414. The L-shaped connecting block 413 further pulls the movable sleeve 403 to move away from the limit stop 410 along the first guide slide rod 401 and the second guide slide rod 402. As the movable sleeve 403 slides, the strip-shaped movable shell 405 moves synchronously, and the strip-shaped brush 407 at its bottom rubs against the inner bottom wall of the CNC machine tool body 1, sweeping the iron filings on the inner bottom wall toward the waste inlet hole 6.

[0034] During this process, when the strip-shaped movable housing 405 separates from the touch switch 411, the touch switch 411 loses pressure and triggers the air pump 408 to start. The airflow generated by the air pump 408 is delivered to the interior of the strip-shaped movable housing 405 through the corrugated air guide pipe 409, and then sprayed out through several downward-sloping air nozzles 406. The airflow blows away the stubborn iron filings attached to the inner bottom wall, forming a double cleaning effect of brushing and blowing with the strip brush 407, ensuring that there are no iron filings left.

[0035] The scrap metal, propelled by the strip brush 407 and aided by airflow, gradually moves to the scrap inlet 6 on the left inner wall of the CNC machine tool body 1. It then falls directly into the scrap collection trough 5 below through the inlet 6, achieving directional collection of the scrap metal. When the collected scrap metal needs to be processed, the operator simply rotates and opens the discharge cover 7 on the left side of the CNC machine tool body 1 to remove the scrap metal from the collection trough 5. After the operation is complete, the discharge cover 7 is closed, awaiting the next cleaning operation. The entire process requires no manual entry into the CNC machine tool body 1 for wiping, and there is no splashing or secondary scattering of scrap metal, balancing safety and cleaning efficiency.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
