Description

Technical Field

[0001] This invention relates to the field of CNC technology, specifically to a cleaning mechanism for a CNC milling machine used in machining mechanical parts. Background Technology

[0002] When machining mechanical parts for precision, production is carried out using machines such as CNC milling machines. Multi-axis control can be performed according to machining requirements to improve machining stability. A cleaning mechanism is also set up to clean up the waste chips. However, during use, the cleaning mechanism can only clean up the waste chips within the cutting area, and the cleaning force is relatively low.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application CN202010597558.8, filed on 2020-06-28) provides a cleaning device for a CNC milling machine used for processing conveying mechanical parts. Through the coordinated use of a support rod, a convex wheel, a first drive motor, a support frame, a sliding rod, a sliding plate, a connecting plate, a return spring, a first slide rod, a fixed plate, and a second slide rod, it can effectively provide a certain vibration effect during waste collection. This effectively avoids the problem of debris remaining in the device and hindering its recycling, thus effectively improving... This improves the device's chip collection efficiency and effectively avoids the safety hazards posed by chips to workers when manually collecting them. Furthermore, existing technology (Chinese patent application CN202021967398.3, filed on 2020-09-10) provides a CNC milling machine device for easy chip removal. This device collects chips from the worktable, sweeping them directly into a collection box during cleaning, preventing them from spilling onto other parts of the milling machine or falling directly to the ground. It features a simple structure and convenient use. (Chinese patent application CN202123100381.5, filed on 2021-12-11) A CNC milling machine for easy cleaning and collection of milling chips, comprising a motor, a screw, a threaded sleeve, a connecting plate, a push plate, and a hydraulic telescopic rod. In operation, starting the motor rotates the screw, causing the threaded sleeve to slide on the threaded surface, thereby moving the connecting plate closer to the center. During this movement, the connecting plate causes the push plate to slide along the bottom of the machining table. The hydraulic telescopic rod, in conjunction with the screw, increases the pushing speed. The moving distance of the plate enables the push plate to slide along the bottom of the machining table. During the sliding process of the push plate, the milling chips are pushed and pushed out through the chip removal groove from the bottom of the machining table, cleaning the inside of the machining table and avoiding affecting operation. Although the existing technology can clean up the waste chips, it is difficult to clean the waste chips on the inner wall of the CNC milling machine during operation, especially when performing large-scale processing. Manual cleaning affects work efficiency and it is inconvenient to discharge the filtered waste chips, affecting the waste chip cleaning effect.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing cleaning mechanism of CNC milling machines. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning mechanism for CNC milling machines used in machining mechanical parts, in order to solve the problem mentioned in the background art that it is difficult to clean the waste chips on the inner wall of the CNC milling machine during operation, especially when performing mass production. Manual cleaning affects work efficiency and it is inconvenient to discharge the filtered waste chips, thus affecting the waste chip cleaning effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a CNC milling machine cleaning mechanism for machining mechanical parts, comprising a CNC milling machine body for machining, wherein machining components are mounted on the inner surface of the CNC milling machine body, and a waste chip collection component is mounted on the lower surface of the machining components; comprising: a reciprocating lead screw, which rotates within the inner wall of the CNC milling machine body, wherein a slider is threadedly slidably mounted on the inner surface of the reciprocating lead screw, and a rotating component is rotatably mounted on the inner surface of the slider, wherein a lifting component is mounted on the outer surface of the rotating component, and the lifting component slides within the inner wall of the CNC milling machine body, and the lifting component passes through the outer surface of the reciprocating lead screw, and the lifting component is provided with a magnetic suction nesting mechanism; a second synchronous belt, which rotates below the outer surface of the reciprocating lead screw, and the other end of the second synchronous belt is connected to a bevel gear set via a shaft, wherein a helical rod rotates on the vertical gear shaft of the bevel gear set, and the helical rod rotates on the inner surface of the waste chip collection component, and the waste chip collection component is provided with a waste chip cleaning mechanism.

[0007] Preferably, the CNC milling machine body and the reciprocating lead screw form a rotating structure, and the reciprocating lead screw forms a reciprocating lifting structure with the lifting component through the slider and the rotating component, and the lifting component and the reciprocating lead screw form a through structure.

[0008] The above structure allows for effective control of the lifting components during use, improving cleaning efficiency and reducing the need for manual intervention.

[0009] Preferably, the magnetic nesting mechanism includes a magnetic plate one installed on the inner surface of the lifting component, and a magnetic plate two magnetically connected to the outer surface of the magnetic plate one. A support rod is nested on the outer surface of the magnetic plate two and limits the sliding of the support rod on the inner surface of the lifting component. At the same time, the support rod is provided with a rotating cleaning mechanism. The lifting component and the support rod form an internal nesting structure, and the support rod forms a magnetic sliding structure with the lifting component through the magnetic plate two and the magnetic plate one.

[0013] Preferably, the support rod forms a rotating structure with the nozzle and the spray pipe, and the nozzle is set at equal distances from the outer surface of the spray pipe.

At the same time, the top pressing block and the bottom pressing block form an integrated structure with the CNC milling machine body, and the top pressing block and the bottom pressing block are staggered on the inner surface of the CNC milling machine body.

[0014] With the above structure, it is easy to control the lateral movement of the nozzle support rod during use, thereby controlling the nozzle to rotate continuously and elastically reset.

[0015] Preferably, the inner surface of the support rod is rotatably connected to a toothed gear, and the outer surface of the toothed gear is meshed with a rack. A tension spring is elastically connected between the toothed gear and the support rod. At the same time, the outer surface of the toothed gear is rotatably connected to a timing belt, and the other end of the timing belt is nested and rotated on the outer surface of the nozzle.

[0016] With the above structure, the rotation of the toothed gear can effectively control the synchronous belt assembly of the nozzles to rotate in linkage. When the nozzles move up and down to replace different toothed gears to drive the rotation, the left and right adjustment of the support rod and the tension roller for squeezing can be used to prevent another set from affecting its rotation effect.

[0017] Preferably, the support rod forms an elastic rotating structure with the toothed gear through a tension spring, and the toothed gear forms a meshing structure with the rack. The toothed gear is set at an equal angle about the middle section of the inner surface of the support rod, and the toothed gear forms a rotating structure with the nozzle through a synchronous belt.

[0018] With the above structure, the nozzle can be stably adjusted to rotate in conjunction with different toothed gears during use, and the nozzle can be controlled to continuously clean from multiple angles.

[0019] Preferably, the reciprocating lead screw forms a rotating structure with the bevel gear set via a timing belt, and the bevel gear set forms a rotating structure with the screw rod.

[0022] With the above structure, it is easy to control the movement of the push plate by adjusting the up and down of the cleaning mechanism after filtration, clean the waste debris after filtration, and discharge it through the debris conveyor belt.

[0023] Preferably, the waste collection component forms a telescopic cleaning structure with the push plate through a telescopic assembly and a telescopic rod, and the outer surface of the push plate has an inverted "L" shape. The telescopic assembly forms a telescopic structure through a hydraulic pipe and a hydraulic chamber, while the hydraulic chamber forms a squeezing structure with the lifting component through a hydraulic rod.

[0024] With the above structure, the cleaning mechanism and the central collection mechanism are used in conjunction with the chip removal mechanism during use.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. This CNC milling machine cleaning mechanism for machining mechanical parts is equipped with a lifting component that is easy to adjust up and down, and a support rod that moves left and right. It controls the angle adjustment of the cleaning nozzle and spray head during the up and down process to increase the cleaning range. During long-term operation, it reduces the need for personnel intervention to avoid affecting work efficiency. Through the cooperation of the toothed gear, synchronous belt and tensioning wheel, the nozzle is controlled to rotate at different positions during the up and down process. The cleaning waste is collected by the screw rod and discharged in conjunction with the push plate and the chip conveyor belt.

[0026] 2. The cleaning mechanism of the CNC milling machine for machining mechanical parts is equipped with a magnetic nesting mechanism, which facilitates the nesting assembly of the nesting rod when the lifting part moves up and down. In addition, with the cooperation of magnetic accumulator one and magnetic accumulator two between the two, it prevents the support rod from falling off and excessively sliding when it moves left and right, thus controlling the stability of the support rod.

[0027] 3. The cleaning mechanism of this CNC milling machine for machining mechanical parts is equipped with a rotary cleaning mechanism. Through the rotation of the toothed gear, in conjunction with the timing belt and tensioning pulley, the angle of the nozzle on the spray pipe is adjusted, thereby controlling the cleaning range. The tensioning pulley, as the support rod moves, controls the operation of the timing belt at the corresponding position, preventing another timing belt from interfering with the rotary cleaning. Furthermore, by coordinating the toothed gear with the left-right adjustment of the support rod as it moves up and down, the toothed gears on both sides of the support rod are synchronously controlled to work alternately, ensuring that the continuous rotary cleaning operation of the spray pipe is not affected during lifting and lowering. Furthermore, the waste chip cleaning mechanism, through the cooperation of the spiral rod and waste chip collection component, and connected to the drive of the reciprocating screw, collects waste chips into the cutting fluid tank. The push plate, through a telescopic component, adjusts with the lifting component, controlling the movement of the hydraulic chamber and hydraulic rod, thereby controlling the push plate to push the filtered waste chips out.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 The present invention provides a technical solution: a CNC milling machine cleaning mechanism for machining mechanical parts, comprising a CNC milling machine body 1 for machining, wherein a machining component 2 is mounted on the inner surface of the CNC milling machine body 1, and a waste chip collection component 19 is mounted on the lower surface of the machining component 2.

[0032] Example 1: As Figures 1-6The present invention provides the following technical solution: a cleaning mechanism for a CNC milling machine used for machining mechanical parts, comprising: a reciprocating lead screw 3, which rotates within the inner wall of the CNC milling machine body 1, and a slider 4 is threadedly mounted on the inner surface of the reciprocating lead screw 3; a rotating component 5 is mounted on the inner surface of the slider 4; a lifting component 6 is mounted on the outer surface of the rotating component 5, and the lifting component 6 slides within the inner wall of the CNC milling machine body 1; the lifting component 6 passes through the outer surface of the reciprocating lead screw 3; and the lifting component 6 is provided with a magnetic nesting mechanism; the CNC milling machine body 1 and the reciprocating lead screw 3 form a rotating structure. The structure includes a reciprocating lead screw 3 connected to a lifting member 6 via a slider 4 and a rotating component 5, forming a reciprocating lifting structure. The lifting member 6 and the reciprocating lead screw 3 form a through-type structure. The magnetic nesting mechanism includes a magnetic suction plate 7 mounted on the inner surface of the lifting member 6, and a magnetic suction plate 8 magnetically connected to the outer surface of the magnetic suction plate 7. A support rod 9 is nested on the outer surface of the magnetic suction plate 8, limiting its sliding position on the inner surface of the lifting member 6. The support rod 9 is also equipped with a rotating cleaning mechanism. The lifting member 6 and the support rod 9 form an internal nesting structure, and the support rod 9 is magnetically attracted to the lifting member 6 via the magnetic suction plate 8 and the magnetic suction plate 7. The sliding structure and rotating cleaning mechanism include a nozzle 10 rotatably connected to the inner surface of a support rod 9, with a nozzle 11 mounted on the outer surface of the nozzle 10. An extrusion wheel 12 is nested and rotatably mounted at the corner of the inner surface of the support rod 9. A top extrusion block 13 and a bottom extrusion block 14 are respectively connected to the outer surface of the extrusion wheel 12, and the top extrusion block 13 and bottom extrusion block 14 are mounted on the inner wall of the CNC milling machine body 1. The support rod 9 forms a rotating structure with the nozzle 10 and the nozzle 11, with the nozzle 11 equidistant from the outer surface of the nozzle 10. The support rod 9 is connected to the top extrusion block 11 via the extrusion wheel 12. The top extrusion block 13 and the bottom extrusion block 14 form an extrusion structure. At the same time, the top extrusion block 13 and the bottom extrusion block 14 form an integrated structure with the CNC milling machine body 1. The top extrusion block 13 and the bottom extrusion block 14 are staggered on the inner surface of the CNC milling machine body 1. The inner surface of the support rod 9 is rotatably connected to the toothed gear 15, and the outer surface of the toothed gear 15 is meshed with the rack 16. The toothed gear 15 and the support rod 9 are elastically connected to the tension spring 17. At the same time, the outer surface of the toothed gear 15 is rotatably connected to the timing belt 18, and the other end of the timing belt 18 is nested and rotated on the outer surface of the nozzle 10.

[0033] In operation, the CNC milling machine body 1 controls the operation of the machining component 2 to process mechanical parts. When waste accumulates on the machining component 2 and the waste collection component 19, the motors assembled on both sides of the CNC milling machine body 1 are activated to control the rotation of different sets of reciprocating screws 3, thereby controlling the slider 4 to slide on the reciprocating screw 3. The rotating component 5 assembled with the slider 4 is controlled to adjust the lifting component 6 to move downward. Simultaneously, the lifting component 6, in conjunction with the magnetic suction plate 7 and magnetic suction plate 8, magnetically attracts and nests the support rod 9 to move downward. When the support rod 9 moves downward, it drives the built-in toothed gear 15 to engage with the rack 16 inside the CNC milling machine body 1 in stages. This drives the timing belt 18 assembled with the toothed gear 15, controlling the nozzle 10 to rotate on the support rod 9. When the timing belt 18 is in use, it works with the pressure of the tension wheel to control the stable rotation of the nozzle 10. The timing belt 18 on the symmetrical side of the nozzle 10 disengages from the tension wheel. The compression prevents interference with the rotation and cleaning of the nozzle 11 assembled in the nozzle 10. When the lifting component 6 and the support rod 9 move to the underside of the reciprocating screw 3, the compression of the support rod 9 by the nested rotating compression wheel 12 and the bottom compression block 14 controls the magnetic translation of the support rod 9 on the lifting component 6. The use of magnetic suction plates 7 and 8 prevents excessive translation. At the same time, the toothed gear 15 assembled on the front side of the support rod 9 will be positioned opposite to another set of racks 16, and the toothed gear will be controlled. The timing belt 18 on the front side of the support rod 9 connected to 15 is tensioned, and the timing belt 18 on the rear side of the support rod 9 is disengaged from the tensioning wheel control. This ensures that the rotation of the nozzle 10 and the nozzle 11 is not affected when the lifting component 6 moves upward, thus improving the cleaning effect of the nozzle 11. When the lifting component 6 moves to the top, the extrusion wheel 12 on the upper rear side of the support rod 9 will contact the top extrusion block 13, controlling the translation of the support rod 9, thereby controlling the initial toothed gear 15 to connect and improving the stability of continuous cleaning.

[0034] Example 2: Figure 1 , Figure 2 and Figure 7The technical solution shown, based on Embodiment 1, further discloses a centrally located waste collection mechanism, the specific details of which are as follows: A second synchronous belt 20 rotates below the outer surface of the reciprocating lead screw 3, and the other end of the second synchronous belt 20 is connected to a bevel gear set 21 via a shaft. The vertical gear shaft of the bevel gear set 21 rotates to a helical rod 22, which rotates on the inner surface of the waste collection component 19. Simultaneously, the waste collection component 19 is equipped with a waste cleaning mechanism; the support rod 9 forms a spring with the toothed gear 15 via a tension spring 17. The structure is a rotary structure, and the toothed gear 15 and the rack 16 form a meshing structure. The toothed gear 15 is set at an equal angle to the middle section of the inner surface of the support rod 9. At the same time, the toothed gear 15 and the nozzle 10 form a rotary structure through the timing belt 18. The reciprocating screw 3 forms a rotary structure through the timing belt 20 and the bevel gear set 21. The bevel gear set 21 and the screw rod 22 form a rotating structure. The screw rod 22 and the waste collection component 19 form a waste conveying structure. At the same time, the outer surface of the screw rod 22 has a symmetrical structure.

[0035] When the reciprocating screw 3 rotates for cleaning, it drives the timing belt 20 connected to the bottom to adjust the bevel gear set 21 to rotate, and controls the vertical gear control screw 22 of the bevel gear set 21 to rotate in the waste chip collection component 19, causing the waste chips collected by the waste chip collection component 19 to move to the upper side of the filter component 23, filter the waste chips, and filter out the cutting fluid and deliver it to the cutting fluid tank 24 for recycling.

[0036] Example 3: Figure 1 , Figure 2 and Figure 8 The technical solution shown, based on Embodiment 2, further discloses the discharge of waste chips, the specific details of which are as follows: The waste chip cleaning mechanism includes a filter element 23 installed on the inner surface of the waste chip collection component 19, and a chip liquid chamber 24 is provided on the lower side of the inner surface of the waste chip collection component 19. A push plate 25 is slidably connected to the inner surface of the waste chip collection component 19, and a telescopic rod 26 is installed on the outer surface of the push plate 25. A telescopic assembly 27 is telescopically connected to the outer surface of the telescopic rod 26. A chip discharge conveyor belt 28 is rotatably connected to the rear side of the inner surface of the waste chip collection component 19, and the telescopic assembly 27... A hydraulic pipe 29 is installed on the rear side of the outer surface of the device, and a hydraulic chamber 30 is installed on the left side of the outer surface of the hydraulic pipe 29. A hydraulic rod 31 is telescopically connected to the inner surface of the hydraulic chamber 30, and the hydraulic rod 31 is installed on the lower surface of the lifting component 6. The waste collection component 19 forms a telescopic cleaning structure with the push plate 25 through the telescopic assembly 27 and the telescopic rod 26. The outer surface of the push plate 25 is shaped like an inverted "L". The telescopic assembly 27 forms a telescopic structure with the hydraulic pipe 29 and the hydraulic chamber 30. At the same time, the hydraulic chamber 30 forms a squeezing structure with the lifting component 6 through the hydraulic rod 31.

[0037] While the waste chips on the waste chip collection component 19 are collected in the center, the hydraulic oil in the hydraulic oil chamber 30 is squeezed by the downward movement of the lifting component 6, and the hydraulic oil is delivered to the telescopic component 27. The push plate 25 installed on the extrusion telescopic rod 26 slides in the chip liquid chamber 24, and the push plate 25 is controlled to push the centered waste chips onto the chip discharge conveyor belt 28 and discharge them from the rear side of the CNC milling machine body 1. The shape of the push plate 25 is set to avoid the situation of waste chip obstruction when the push plate 25 is reset, thereby improving the stability of waste chip discharge.
