Description

Technical Field

[0001] This invention relates to the field of flange and bushing machining technology, specifically to a CNC machine tool for flange and bushing machining. Background Technology

[0002] Flange bushings are key connecting components commonly used in mechanical transmissions, hydraulic pipelines, and engineering machinery assembly. They are typically made from round steel, alloy steel, or other metal blanks, and are precision machined on CNC lathes and CNC milling machines to shape the outer diameter, inner hole, flange end face, and chamfer. During the batch CNC machining of flange bushings, the cutting process between the tool and the workpiece generates a large amount of metal chips, fine dust, and high-temperature debris. This debris is scattered over a wide area and consists of a mixture of coarse and fine particles.

[0003] Currently, most ordinary CNC machine tools used for flange and bushing machining lack dedicated, integrated chip protection and automatic collection structures, resulting in numerous technical defects and usage drawbacks. The horizontal and vertical linear lead screw drive mechanisms of existing CNC machine tools are mostly directly exposed next to the machining area. Metal chips and fine dust generated during cutting easily fall and become lodged in the movement clearances of the lead screw, guide rail, slider, and bearings. Long-term use can easily cause problems such as guide rail damage, lead screw wear, slider jamming, and feed deviation. This not only reduces the dimensional accuracy and consistency of flange and bushing machining but also significantly increases the probability of failure and maintenance / replacement costs of the linear drive mechanism, shortening the service life of the machine tool's precision transmission components. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a CNC machine tool for machining flange bushings, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a CNC machine tool for machining flange bushings, comprising a machining machine tool, wherein an adsorption mechanism is fixedly installed on the side of the machining machine tool via a bracket, a transverse linear screw drive mechanism for driving a vertical linear screw drive mechanism to move laterally is installed in the middle of the adsorption mechanism, a vertical linear screw drive mechanism is installed on the surface of the transverse linear screw drive mechanism, a vertically movable tool holder is installed on the vertical linear screw drive mechanism, a collection mechanism is installed on both the left and right sides of the adsorption mechanism and the vertical linear screw drive mechanism, and a collection machine is installed on both the left and right end surfaces of the adsorption mechanism and on the sides of the collection mechanism;

[0006] The adsorption mechanism consists of several adsorption strips, which are fixed to each other. A control channel is fixedly installed on the top of each adsorption strip, and a drive channel is fixedly connected to the rear of each control channel. A first magnet block is slidably connected inside the drive channel. A sealing plug is fixedly installed at the front end of each first magnet block, and a first spring is sleeved on the outside of each sealing plug. A connecting groove is opened inside each control channel, and a discharge hole is opened inside the control channel and at the front end of the connecting groove. One end of the discharge hole extends into the adsorption strip. A pipe is fixedly installed at the bottom of the drive channel, and one end of the pipe and the discharge hole both extend into the connecting groove. A first negative pressure pump is fixedly connected to the rear of one of the adsorption strips, and one end of the first negative pressure pump is connected to the inside of the pipe.

[0007] Those skilled in the art will understand that by integrating an adsorption mechanism, a horizontal linear screw drive mechanism, a vertical linear screw drive mechanism, a collection mechanism, and a summarizing machine into an integrated layout on the outside of the machine tool, an integrated structure for processing, protection, chip suction, chip collection, and unloading is formed. Multiple sets of adsorption strips, in conjunction with a first negative pressure pump, pipes, and discharge holes, construct a partitioned negative pressure adsorption air duct. This allows for the immediate adsorption of splashing chips and dust during flange and bushing cutting, preventing chips from scattering, falling into, and intruding into the gaps between the screw, guide rail, and slider of the linear screw drive mechanism, thus avoiding damage, jamming, and abnormal wear of precision transmission components by chips. Simultaneously, the modular structure of multi-segment adsorption strips facilitates on-site disassembly, maintenance, and partial replacement of individual parts. The closed air duct layout effectively reduces negative pressure leakage, improves overall chip capture efficiency, and adapts to the actual working conditions of large-volume, continuous cutting of flange and bushings.

[0008] Preferably, a connecting frame is fixedly installed at the top of the vertical linear screw drive mechanism, and a second magnet block is fixedly installed at the rear end of the connecting frame. The second magnet block and the first magnet block are magnetically repelled.

[0009] Those skilled in the art will recognize that this structure utilizes a second magnet block that moves synchronously with the vertical linear screw drive mechanism, forming a purely mechanical magnetic repulsion linkage trigger structure with the first magnet block. Without the need for additional electrical switches, sensors, or control circuits, it automatically drives the sealing plug to switch between sealing and opening the connecting groove and the exhaust port air passage as the tool holder moves. Negative pressure adsorption is precisely activated only in the actual machining area, while the air supply is automatically shut off in non-operational idle areas. This significantly saves energy consumption of the negative pressure pump and reduces ineffective suction loss, while also achieving precise chip suction in zonal zones, avoiding energy waste caused by constant pressure adsorption throughout the process. Furthermore, the magnetic repulsion drive method eliminates hard mechanical contact wear, and the structure is resistant to oil and dust, has a low failure rate, and can adapt to the harsh machining environment of CNC machine tools with high dust and high cutting fluid content for extended periods.

[0010] Preferably, the collecting mechanism includes a movable collecting box and a fixed collecting box. The movable collecting box is installed on both sides of the vertical linear screw drive mechanism, and the fixed collecting box is installed on the left and right end surfaces of the adsorption mechanism. Both the fixed and movable collecting boxes have a winding roller rotatably connected inside via bearings. Two magnetic repulsion rings are fixedly sleeved on the outer side of each winding roller. A perforated strip is installed on the outer side of one winding roller, with one end of the perforated strip fixedly connected to the outer side of another winding roller. A drive box is fixedly connected to the top of each fixed collecting box, with the top of the drive box fixedly connected to one end of a spring. The other end of the spring is connected to one end of the winding roller. A first motor is fixedly connected to the top of the connecting frame, above the movable collecting box. The output end of the first motor is fixedly connected to the top of the corresponding winding roller. A track is fixedly connected to the surface of the adsorption strip, with both ends of the track passing through the movable collecting box, the fixed collecting box, and the vertical linear screw drive mechanism, respectively.

[0011] Those skilled in the art will recognize that this structure employs a paired arrangement where a mobile collection box follows the vertical linear screw drive mechanism, and a fixed collection box is installed at a fixed point. This, combined with the winding roller, spring, and first motor, enables automatic winding and unwinding of the perforated belt, and cyclic traction operation. The perforated belt's encircling arrangement forms a closed protective barrier, physically preventing chips from seeping into the side and bottom gaps of the linear screw drive mechanism. The spring provides constant winding tension, and the first motor actively adjusts the unwinding speed, ensuring the perforated belt remains taut and flat throughout, preventing slackness, sagging, and protective gaps. The through-track installation provides basic guidance and limits for the perforated belt's operation, preventing deviation, wrinkling, and deformation, ensuring the protective barrier is continuous and unbroken, further enhancing the overall reliability of dust and chip protection for the linear drive mechanism.

[0012] Preferably, a plurality of telescopic guide mechanisms are fixedly connected to the top and bottom of the perforated strip, and the telescopic guide mechanism includes a guide housing. A second spring is fixedly connected to one end of the inner cavity of the guide housing. A push plate is fixedly connected to one end of the second spring. A magnetic repulsion column is fixedly connected to one end of the push plate. One end of the magnetic repulsion column is inserted into the track. An L-shaped magnetic repulsion plate is fixedly connected to the inner wall of the fixed collection box and the movable collection box above the track. The L-shaped magnetic repulsion plate and the magnetic repulsion ring are magnetically repelled by the magnetic repulsion column. One end of the L-shaped magnetic repulsion plate is in contact with the outer side of the magnetic repulsion ring.

[0013] Those skilled in the art will recognize that this structure, through a telescopic guide mechanism, a second spring, a push plate, and magnetic repulsion posts, combined with an L-shaped magnetic repulsion plate and a magnetic repulsion ring, constitutes a purely mechanical magnetic repulsion automatic telescopic limiting structure. During normal conveying of the perforated belt, the magnetic repulsion posts engage with the track to achieve precise vertical limiting, effectively preventing wrinkles, lateral shifts, loosening, and misalignment of the perforated belt that could cause protective gaps. When the perforated belt passes through the magnetic repulsion area during winding, the magnetic repulsion force automatically forces the magnetic repulsion posts to retract and avoid them, smoothly completing the winding and storage. After unwinding and leaving the magnetic repulsion area, the second spring automatically pushes the magnetic repulsion posts back into place and engages with the track. The entire process requires no manual adjustment or electrical control components. This ensures the perforated belt maintains stable and leak-free operation while adhering to the track, completely preventing fine metal dust and chips from entering the linear screw drive mechanism through the gaps on the side of the perforated belt. It also significantly improves the smoothness of the perforated belt's winding and unwinding operation and extends its service life.

[0014] Preferably, the summarizing machine includes a summarizing box, which is installed on the side of a fixed collection box. The bottom of the summarizing box has two bottom discharge ports. The top of the inner cavity of the summarizing box is rotatably connected to a rotating tube via a bearing. The bottom end of the rotating tube is fixedly connected to a collecting roller. The side of the summarizing box has a scraping inlet. The inside of the collecting roller has three storage cavities. The outer side of the collecting roller and the side of the storage cavity each has an inlet. The top of the inner cavity of each storage cavity is fixedly connected to an isolation net.

[0015] Those skilled in the art will recognize that the collecting machine employs a collecting roller structure with three storage chambers built into the collecting box. Combined with a side scraping inlet, it can mechanically scrape and separate the chips adsorbed on the surface of the perforated belt, completing chip removal without manual intervention. The three independent storage chambers can take turns performing chip suction, temporary storage, and automatic unloading simultaneously, supporting continuous processing without stopping the machine and without occupying production time. An isolation net is installed at the top of the storage chamber to effectively prevent metal dust from entering the rear negative pressure pipeline and air passage, preventing pipeline blockage, dust accumulation and damage to the negative pressure pump, and extending the service life of negative pressure components. The bottom discharge port can guide the falling chips in a directional and concentrated manner.

[0016] Preferably, a mounting box is fixedly connected to the top of the collection box, a rotary joint is installed on the top of the mounting box, the top end of the rotating tube is connected to the bottom end of the rotary joint, a second negative pressure pump is installed on the side of the mounting box, one end of the second negative pressure pump is connected to the top end of the rotary joint, a second motor is installed on the top of the mounting box, the output end of the second motor extends into the interior of the mounting box, and meshing transmission gears are fixedly fitted on both the output end of the second motor and the outer side of the rotating tube.

[0017] Those skilled in the art will understand that this structure uses a second motor to drive the rotating tube and collecting roller to rotate at low speed through meshing transmission gears. Combined with a rotary joint, it achieves airtight connection between the static negative pressure pipeline and the rotating working chamber, effectively solving the technical problems of negative pressure pipeline entanglement and interface leakage under rotating conditions. The second negative pressure pump provides a stable and balanced negative pressure suction to each storage chamber with the help of the rotary joint, ensuring that the scraped chips are quickly and stably sucked into the storage chamber and are not easy to scatter and flow back. The gear meshing transmission has a precise transmission ratio and stable operation, which can realize the uniform and slow rotation of the collecting roller. The whole machine has a compact structure and high transmission reliability, and can complete the chip collection and chamber rotation work automatically for a long time without manual intervention.

[0018] Preferably, each of the three openings of the rotating tube is fixedly connected to a branch pipe, and each of the tops of the collecting roller and one end of the branch pipe is fixedly connected to a connecting box. Each of the connecting boxes is fixedly connected to a fixing box at its rear end. One end of each branch pipe is inserted into the connecting box. Each of the connecting boxes has a collection hole at its rear end and a connecting hole at its bottom end. Each branch pipe communicates with the inside of the connecting hole through the collection hole, and the bottom end of the connecting hole extends into the storage cavity.

[0019] Those skilled in the art will know that by constructing independent negative pressure pathways for each cavity through branch pipes, connecting boxes, summing holes, and connecting holes, independent air path control can be achieved for each of the three storage cavities. Each cavity is not cross-contaminated with air, and the negative pressure suction is evenly distributed, avoiding problems such as suction attenuation and weak local debris suction. The pipeline layered connection layout is regular and has good sealing performance, reducing negative pressure leakage loss.

[0020] Preferably, each of the fixed boxes is rotatably connected to a reciprocating threaded shaft via bearings. A plug is fitted on the outer side of the reciprocating threaded shaft, with one end of the plug inserted into the collection hole. A rotating shaft is rotatably connected to the lower end of one end of the fixed box via bearings. A drive gear is fixedly sleeved on the outer side of the bottom end of the rotating shaft. The top end of the rotating shaft extends to the top of the fixed box. Meshing bevel gears are fixedly sleeved on the outer side of one end of both the rotating shaft and the reciprocating threaded shaft. Tooth segments that cooperate with the drive gears are fixedly connected to the inner wall of the collection box on both sides of the scraping inlet. The bottom end of the storage cavity extends to the bottom of the collecting roller.

[0021] Those skilled in the art will understand that this structure utilizes the meshing of the toothed segments on the inner wall of the collection box with the driving gear, which drives the reciprocating threaded shaft to rotate via bevel gear transmission, thereby driving the plunger to move back and forth linearly, automatically completing the sealing and opening of the collection hole, realizing a purely mechanical follow-up negative pressure automatic on / off control; when the collecting roller rotates to the unloading position, the negative pressure is automatically cut off, and the chips fall naturally by their own weight for unloading; when it rotates to the chip suction position, the negative pressure is automatically turned on to resume chip collection, without the need for solenoid valves, controllers, and sensing elements, and it is resistant to oil, dust, and electromagnetic interference, with an extremely low failure rate; the bottom of the storage cavity has a straight through design with no dead corners for chip accumulation, ensuring thorough unloading without residue, and with the lower storage structure, it can realize automatic centralized collection of chips, greatly reducing the frequency of manual chip cleaning.

[0022] This invention provides a CNC machine tool for machining flange bushings, which has the following advantages:

[0023] 1. This invention, by setting an adsorption mechanism on the side of the machine tool and forming a closed protective structure with a perforated strip, can comprehensively intercept and adsorb metal debris splashed and scattered during the flange bushing processing. It can effectively prevent debris and dust from entering the interior of the horizontal and vertical linear screw drive mechanisms from both physical isolation and negative pressure adsorption levels, avoiding debris from getting stuck in the machine tool gaps and maintaining the machining accuracy and motion stability of the CNC machine tool for a long time. At the same time, it avoids the wear, corrosion and lubrication failure of transmission components caused by debris accumulation, greatly reducing the failure probability and maintenance and replacement costs of the linear drive mechanism, and effectively extending the service life of the machine tool's precision transmission components and the whole machine.

[0024] 2. This invention employs a magnetic repulsion mechanism between a first magnet block and a second magnet block, which, in conjunction with a first spring, a sealing plug, a control channel, and a drive channel, forms a follow-up on / off structure. This structure can follow the left and right movement of the vertical linear screw drive mechanism, automatically opening and closing the air passages in the corresponding areas. Negative pressure adsorption is only activated in the actual processing area of ​​the tool holder, while the air is automatically shut off in the idle area. This achieves adaptive follow-up negative pressure chip collection, avoiding waste of adsorption energy, reducing the workload and energy consumption of the negative pressure pump, and ensuring concentrated adsorption force and high chip capture efficiency in the working area, without negative pressure leakage or suction loss.

[0025] 3. The present invention is equipped with a collection mechanism consisting of a mobile collection box, a fixed collection box, a winding roller, a spring, a first motor, and a track. This mechanism enables the perforated tape to automatically wind and unwind as the tool holder moves, maintaining the integrity of the protective barrier without any gaps. At the same time, it can automatically pull and transport the perforated tape with adsorbed debris towards the collection machine, realizing full automation of the conveying and collection of processing debris. This eliminates the need for frequent manual cleaning of machine tool debris and tidying of the protective structure, significantly reducing labor intensity and improving the automation level of the equipment.

[0026] 4. This invention features telescopic guide mechanisms at the top and bottom of the perforated belt, which, together with the track, L-shaped magnetic repulsion plate, magnetic repulsion ring, and magnetic repulsion column, form a purely mechanical magnetic repulsion limiting structure. During normal operation of the perforated belt, the magnetic repulsion column engages with the track for upper and lower limiting, preventing the perforated belt from deviating, wrinkling, or sagging and creating protective gaps. When the perforated belt is wound up, it automatically compresses and retracts due to magnetic repulsion to avoid obstacles. After unwinding and leaving the magnetic repulsion area, it is automatically lifted and reset by a second spring. No manual adjustment is required throughout the process, ensuring that the perforated belt is always taut, flat, and well-sealed, preventing debris from entering the linear drive mechanism from the side and bottom gaps, thus providing strong protection reliability.

[0027] 5. This invention features a collection machine that utilizes a second motor and transmission gears to drive the rotating tube and collecting roller to rotate. The collecting roller has three independent storage chambers that work in rotation, sequentially performing mechanical scraping, negative pressure suction, temporary storage in the chambers, and automatic unloading. Through the linkage of toothed segments, drive gears, bevel gears, and reciprocating threaded shafts, the plug automatically seals or opens the collection hole, achieving purely mechanical automatic switching of negative pressure on and off in the storage chambers. No additional sensors or electrical control are required. The structure is dust-resistant, oil-resistant, and has a low failure rate. At the same time, the isolation net can prevent metal dust from entering the negative pressure air path, avoiding blockage and damage to the second negative pressure pump and extending the service life of the negative pressure equipment.

[0028] 6. The entire process of chip adsorption, conveying, collection, and unloading in this invention can be carried out simultaneously with the machining of flange bushings on machine tools. There is no need to stop the machine to clean the chips. The multi-cavity rotating storage and automatic unloading structure supports the machine tool to carry out continuous and uninterrupted processing for a long time, effectively reducing downtime and significantly improving the production efficiency of batch processing of flange bushings, and adapting to the needs of large-scale production on assembly lines.

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0053] Example 1

[0054] Please see Figures 1 to 15 This embodiment provides a CNC machine tool for flange bushing machining. The core structure includes a machine tool 1, an adsorption mechanism 2, a collection mechanism 3, a vertical linear screw drive mechanism 4, a collection machine 5, and a horizontal linear screw drive mechanism 6. The machine tool 1 serves as the basic carrier for flange bushing machining. The adsorption mechanism 2 is fixedly mounted on its side via a bracket. The adsorption mechanism 2 is used to adsorb debris generated during machining. The horizontal linear screw drive mechanism 6 is installed in the middle of the adsorption mechanism 2. The core function of the horizontal linear screw drive mechanism 6 is to drive the vertical linear screw drive mechanism 4 to move horizontally. A vertically movable tool holder is mounted on the vertical linear screw drive mechanism 4. Through the cooperation of the horizontal and vertical drive mechanisms, the position of the tool holder can be precisely adjusted to meet the machining requirements of different parts of the flange bushing.

[0055] The adsorption mechanism 2 consists of several adsorption strips 201 that are fixed to each other. A control channel 202 is fixedly installed on the top of each adsorption strip 201. A drive channel 203 is fixedly connected to the rear of the control channel 202. A first magnet block 205 is slidably connected inside the drive channel 203. A sealing plug 207 is fixedly installed at the front end of the first magnet block 205. A first spring 206 is sleeved on the outside of the sealing plug 207. The first spring 206 is used to realize the reset of the first magnet block 205 and the sealing plug 207. The control channel 202 has a connecting groove 208 and a discharge hole 209 located at the front end of the connecting groove 208. One end of the discharge hole 209 extends into the interior of the adsorption strip 201. The bottom of the drive channel 203 is fixedly installed with a pipe 204. Both the pipe 204 and the discharge hole 209 extend into the interior of the connecting groove 208 to achieve air passage communication. The rear of one of the adsorption strips 201 is fixedly connected to a first negative pressure pump 212. One end of the first negative pressure pump 212 is connected to the interior of the pipe 204 to draw air from the adsorption mechanism 2, so that the surface of the adsorption strip 201 generates suction.

[0056] A connecting frame 210 is fixedly installed at the top of the vertical linear screw drive mechanism 4. A second magnet block 211 is fixedly installed at the rear end of the connecting frame 210. The second magnet block 211 and the first magnet block 205 are magnetically repelled. The movement of the sealing plug 207 is controlled by the magnetic repulsion force to realize the opening and closing control of the air passage and avoid the waste of suction force.

[0057] The collection mechanism 3 includes a movable collection box 301 and a fixed collection box 302. The movable collection box 301 is installed on both sides of the vertical linear screw drive mechanism 4 and moves synchronously with the vertical linear screw drive mechanism 4. The fixed collection box 302 is installed on the left and right end surfaces of the adsorption mechanism 2 and is fixedly set. Both the fixed collection box 302 and the mobile collection box 301 are rotatably connected to the take-up rollers 303 via bearings. The two take-up rollers 303 are connected by a perforated strip 310, which is used to receive the debris adsorbed by the adsorption mechanism 2. The top of the fixed collection box 302 is fixedly connected to the drive box 308. The top of the drive box 308 is fixedly connected to one end of the spring 309, and the other end of the spring 309 is connected to one end of the take-up roller 303, which is used to realize the automatic winding and resetting of the take-up roller 303. The top of the connecting frame 210, which is located above the mobile collection box 301, is fixedly connected to the first motor 307. The output end of the first motor 307 is fixedly connected to the top of the corresponding take-up roller 303, which is used to drive the take-up roller 303 to rotate actively, so as to realize the precise winding and unwinding of the perforated strip 310. The surface of the adsorption strip 201 is fixedly connected to the track 306. The two ends of the track 306 pass through the movable collection box 301, the fixed collection box 302 and the vertical linear screw drive mechanism 4, respectively, and are used to guide and limit the operation of the perforated strip 310.

[0058] The collecting machine 5 includes a collecting box 501, which is installed on the side of the fixed collection box 302. The bottom of the collecting box 501 has two bottom discharge ports 511 for discharging the collected debris into the collection box 525. The top of the inner cavity of the collecting box 501 is rotatably connected to a rotating tube 502 via a bearing. The bottom end of the rotating tube 502 is fixedly connected to a collecting roller 503. The side of the collecting box 501 has a scraping inlet 510 for scraping off the debris from the surface of the perforated strip 310. The collecting roller 503 has three storage chambers 509 for storing debris. The outer side of the collecting roller 503 and the side of the storage chamber 509 each have an inlet 508 to facilitate the entry of debris into the storage chamber 509. The top of the inner cavity of each storage chamber 509 is fixedly connected to an isolation net 524 to prevent debris from clogging the air passage.

[0059] The working process of this embodiment is as follows: In use, the vertical linear screw drive mechanism 4 and the horizontal linear screw drive mechanism 6 cooperate to drive the tool holder to move, precisely adjust the position of the tool holder, and make the tool holder cooperate with the processing machine tool 1 to complete the flange bushing processing; the debris generated during the processing flies onto the surface of the perforated strip 310, the first negative pressure pump 212 starts, and draws air from the inside of the adsorption strip 201 through the pipe 204, the connecting groove 208 and the discharge hole 209, so that the surface of the adsorption strip 201 generates suction force, adsorbing the debris onto the surface of the perforated strip 310; the horizontal linear screw drive mechanism 6 drives the tool holder to move. When the vertical linear screw drive mechanism 4 moves, it drives the perforated belt 310 to move synchronously. At the same time, the magnetic repulsion between the second magnet block 211 and the first magnet block 205 controls the opening and closing of the air passage of the adsorption mechanism 2 to avoid wasting the suction force. When it is necessary to collect debris, the first motor 307 drives the winding roller 303 to rotate, pulling the debris on the surface of the perforated belt 310 toward the fixed collection box 302. After the debris is scraped off through the scraping inlet 510, it enters the storage cavity 509 of the collection roller 503 and is finally discharged into the collection box 525 through the bottom outlet 511, thus completing the debris collection.

[0060] Example 2

[0061] Based on Example 1, this embodiment adds a telescopic guide mechanism 7 to further improve the stability of the perforated belt 310 during operation. The specific structure is as follows:

[0062] Several telescopic guide mechanisms 7 are fixedly installed at the top and bottom of the perforated belt 310. The telescopic guide mechanism 7 includes a guide housing 701. One end of the inner cavity of the guide housing 701 is fixedly connected to a second spring 703. One end of the second spring 703 is fixedly connected to a push plate 702. One end of the push plate 702 is fixedly connected to a magnetic repulsion column 704. One end of the magnetic repulsion column 704 is inserted into the inside of the track 306 to enhance the stability of the perforated belt 310.

[0063] An L-shaped magnetic repulsion plate 305 is fixedly connected to the inner wall of both the fixed collection box 302 and the movable collection box 301, and above the track 306. The L-shaped magnetic repulsion plate 305 and the magnetic repulsion ring 304 are magnetically repelled by the magnetic repulsion column 704, and one end of the L-shaped magnetic repulsion plate 305 is attached to the outer side of the magnetic repulsion ring 304. This is used to control the magnetic repulsion column 704 to be stored when the perforated tape 310 is wound up, so as to avoid affecting the winding of the perforated tape 310.

[0064] In this embodiment, the working process of the telescopic guide mechanism 7 is as follows: When the perforated tape 310 is wound up, the winding roller 303 drives the magnetic repulsion column 704 of the telescopic guide mechanism 7 to slide inside the track 306, thereby limiting the perforated tape 310; when the magnetic repulsion column 704 moves to below the L-shaped magnetic repulsion plate 305, the magnetic repulsion force between the L-shaped magnetic repulsion plate 305 and the magnetic repulsion column 704 overcomes the supporting force of the second spring 703, pushes the push plate 702 to press down the second spring 703, and the magnetic repulsion column 704 moves down and separates from the track 306, which facilitates the winding of the perforated tape 310; When the telescopic guide mechanism 7 is wound up to the outside of the take-up roller 303 and below the magnetic repulsion ring 304, the magnetic repulsion force between the magnetic repulsion ring 304 and the magnetic repulsion column 704 keeps the magnetic repulsion column 704 in a retracted state. When the take-up roller 303 releases the perforated belt 310, the telescopic guide mechanism 7 is removed from the range of action of the L-shaped magnetic repulsion plate 305 and the magnetic repulsion ring 304. The second spring 703 pushes the push plate 702 and the magnetic repulsion column 704 to move upward. The magnetic repulsion column 704 inserts into the track 306 and repositions the perforated belt 310 to ensure stable operation of the perforated belt 310.

[0065] Example 3

[0066] Based on Example 2, this embodiment optimizes the structure of the collecting machine 5 to achieve alternating use of the storage cavity 509 and automatic discharge of debris. The specific optimized structure is as follows:

[0067] A mounting box 519 is fixedly connected to the top of the collection box 501. A rotary joint 520 is installed on the top of the mounting box 519. The top end of the rotating tube 502 is connected to the bottom end of the rotary joint 520. A second negative pressure pump 523 is installed on the side of the mounting box 519. One end of the second negative pressure pump 523 is connected to the top end of the rotary joint 520. It is used to draw air from the inside of the storage cavity 509 to generate suction and assist in the suction of debris. A second motor 521 is installed on the top of the mounting box 519. The output end of the second motor 521 extends into the inside of the mounting box 519. The output end of the second motor 521 and the outer side of the rotating tube 502 are both fixedly fitted with meshing transmission gears 522. The rotating tube 502 and the collecting roller 503 are driven to rotate by the second motor 521 to realize the alternating use of the storage cavity 509.

[0068] Branch pipes 504 are fixedly connected to the three openings of the rotating pipe 502. A connecting box 505 is fixedly connected to the top of the collecting roller 503 and to one end of the branch pipe 504. A fixing box 506 is fixedly connected to the rear end of the connecting box 505. One end of the branch pipe 504 is inserted into the connecting box 505. A collection hole 513 is opened at the rear end of the connecting box 505, and a connecting hole 512 is opened at the bottom end. The branch pipe 504 communicates with the interior of the connecting hole 512 through the collection hole 513. The bottom end of the connecting hole 512 extends into the storage cavity 509 to realize air passage connection.

[0069] Inside the fixed housing 506, a reciprocating threaded shaft 515 is rotatably connected via bearings. A plug 514 is mounted on the outer side of the reciprocating threaded shaft 515, with one end of the plug 514 inserted into the collection hole 513 to control the air passage between the branch pipe 504 and the storage chamber 509. A rotating shaft 516 is rotatably connected to the lower end of one end of the fixed housing 506 via bearings. A drive gear 518 is fixedly sleeved on the outer side of the bottom end of the rotating shaft 516, and the top end of the rotating shaft 516 extends to the top of the fixed housing 506. Furthermore, bevel gears 517 are fixedly fitted on the outer side of one end of the rotating shaft 516 and the reciprocating threaded shaft 515; toothed segments 507 that cooperate with the drive gear 518 are fixedly connected to the inner wall of the collection box 501 and on both sides of the scraping inlet 510. Through the meshing of the drive gear 518 and the toothed segments 507, the reciprocating threaded shaft 515 is driven to rotate, thereby realizing the movement of the plug 514; the bottom end of the storage cavity 509 extends to the bottom of the collecting roller 503, which facilitates the discharge of debris from the bottom outlet 511.

[0070] In this embodiment, the automatic debris discharge process is as follows: The second motor 521 is started, and its output drives the transmission gear 522 to rotate, thereby driving the rotating tube 502 and the collecting roller 503 to rotate synchronously. The storage cavity 509 rotates with the collecting roller 503. When the fixed box 506 rotates with the collecting roller 503 to the tooth segment 507, the driving gear 518 meshes with the tooth segment 507. The driving gear 518 drives the rotating shaft 516 to rotate, and through the meshing transmission of the bevel gear 517, drives the reciprocating threaded shaft 515 to rotate, causing the plunger 514 to move forward and insert into the collection hole 513. The air passage between the branch pipe 504 and the storage cavity 509 is disconnected. When the storage cavity 509 rotates to above the bottom discharge port 511, the internal debris falls out under gravity and enters the collection box 525 for collection. As the collection roller 503 continues to rotate, the fixed box 506 corresponding to the other storage cavity 509 moves to the toothed section 507, and the drive gear 518 meshes with the toothed section 507 again, causing the plunger 514 to reset. The air passage between the branch pipe 504 and the storage cavity 509 is reconnected, and debris adsorption and storage continue, realizing the alternating use of the storage cavity 509 and the automatic discharge of debris.

[0071] Example 4

[0072] Please see Figures 1 to 15 The present invention provides a technical solution: a storage box 525 is fixedly installed at the bottom of a collection box 501, and a pull-out storage drawer is slidably installed inside the storage box 525. The storage drawer and the storage box 525 are connected by a sliding rail, which can be freely pulled out from the front of the storage box 525 and pushed in to reset. It is used to centrally receive the flange shaft sleeve processing metal scraps and dust that fall from the collection roller 503.

[0073] In actual operation, when the storage cavity 509 filled with debris rotates with the collecting roller 503 to a position directly above the bottom discharge port 511, the bottom opening of the storage cavity 509 is connected to the bottom discharge port 511. The metal debris, which has lost its negative pressure adsorption effect, falls automatically under its own gravity and falls directly into the pull-out storage drawer inside the storage box 525 through the bottom discharge port 511 to complete the automatic collection.

[0074] When the accumulated metal shavings inside the storage drawer reach the rated capacity, the operator simply pulls the drawer outward from the side of the storage box 525 to empty and clean the internal shavings in one go. After cleaning, the drawer is pushed back into the storage box 525 along the slide rail and can then be used again for receiving materials. When the drawer is properly closed, it forms a sealed space, effectively preventing metal dust from flying outward and shavings from falling through gaps, keeping the machine tool and workshop environment clean. Furthermore, the cleaning process does not require stopping the machine or disassembling the entire machine structure, making operation simple and maintenance time-saving.

[0075] In summary, this CNC machine tool for flange bushing machining uses a vertical linear screw drive mechanism 4 and a horizontal linear screw drive mechanism 6 to drive the tool holder to move, adjust the position of the tool holder, and then use the machining machine tool 1 and the tool holder to machine the flange bushing.

[0076] During processing, debris will be generated and will be thrown onto the surface of the perforated strip 310. The first negative pressure pump 212 draws out and discharges the air through the pipe 204, the connecting groove 208, the discharge hole 209, and the inside of the adsorption strip 201, so that the adsorption hole on the surface of the adsorption strip 201 generates suction force, which causes the debris to be adsorbed onto the surface of the perforated strip 310.

[0077] When the horizontal linear screw drive mechanism 6 drives the vertical linear screw drive mechanism 4 to move to the left, the spring 309 on the left drives the winding roller 303 to wind up the perforated belt 310, and the vertical linear screw drive mechanism 4 pulls the fixed collection box 302 outside the winding roller 303 on the right to release it from the outside of the winding roller 303.

[0078] Furthermore, as the vertical linear screw drive mechanism 4 moves, the connecting frame 210 and the second magnet block 211 move together. When the second magnet block 211 moves completely to the rear of the drive channel 203, the magnetic repulsion between the first magnet block 205 and the second magnet block 211 can overcome the supporting force of the first spring 206 on the first magnet block 205, causing the first magnet block 205 to push one end of the sealing plug 207 into the connecting groove 208, blocking the air passage between the discharge hole 209 and the pipe 204. At this time, there is no gas flow between the adsorption strip 201 and the pipe 204, thus avoiding the waste of suction power.

[0079] When the horizontal linear screw drive mechanism 6 drives the vertical linear screw drive mechanism 4 to move to the right, the spring 309 on the right drives the take-up roller 303 to take up the perforated belt 310, and the vertical linear screw drive mechanism 4 pulls the fixed collection box 302 on the outside of the take-up roller 303 on the left to release it from the outside of the take-up roller 303.

[0080] Furthermore, as the vertical linear screw drive mechanism 4 moves, the connecting frame 210 and the second magnet block 211 move together. When the second magnet block 211 moves completely to the outside of the previous drive channel 203, the magnetic repulsion between the first magnet block 205 and the second magnet block 211 cannot overcome the supporting force of the first spring 206 on the first magnet block 205. The first spring 206 pushes the first magnet block 205 and the sealing plug 207 to reset and move, so that one end of the sealing plug 207 moves out of the connecting groove 208, so that the air passage between the discharge hole 209 and the pipe 204, and between the adsorption strip 201 and the pipe 204 is connected, and the suction force continues to be generated.

[0081] When it is necessary to collect the debris on the surface of the perforated strip 310, the vertical linear screw drive mechanism 4 remains stationary. At this time, the output end of the first motor 307 drives the winding roller 303 to rotate, releasing the perforated strip 310 outside the winding roller 303. The spring 309 drives the winding roller 303 to wind up the perforated strip 310, pulling the debris on the surface of the perforated strip 310 towards the fixed collection box 302. When the debris on the surface of the perforated strip 310 enters the scraping inlet 510, it is scraped off by the inner wall of the scraping inlet 510 and shoveled into the storage cavity 509 through the inlet 508. The second negative pressure pump 523 extracts the gas inside the storage cavity 509 through the rotary joint 520, the rotating pipe 502, and the branch pipe 504, the collection hole 513, and the connecting hole 512, so that the storage cavity 509 generates suction, thereby sucking the debris into the storage cavity 509 for storage.

[0082] The output of the second motor 521 drives the transmission gear 522 to rotate, which in turn drives the rotating tube 502 to rotate. The rotating tube 502 then drives the collecting roller 503 to rotate, causing the storage cavity 509 to rotate along with the debris. The fixed box 506 rotates with the collecting roller 503, causing the drive gear 518 to contact the tooth segment 507. The tooth segment 507 then drives the drive gear 518 to rotate, which in turn drives the bevel gear 517 to rotate the reciprocating threaded shaft 515. This causes the reciprocating threaded shaft 515 to drive the plunger 514 to move, inserting one end of the plunger 514 into the collection hole 513. This disconnects the branch pipe 504 from the storage cavity 509, allowing the debris inside the storage cavity 509 to fall into the collection box 525 for collection when it rotates to the top of the bottom discharge port 511.

[0083] As the collecting roller 503 rotates, the other storage cavity 509 also changes position, causing the fixed box 506 corresponding to this storage cavity 509 to rotate with the collecting roller 503. This causes the drive gear 518 to contact the tooth segment 507, which in turn drives the drive gear 518 to rotate. The drive gear 518 then drives the bevel gear 517 to rotate the reciprocating threaded shaft 515. The reciprocating threaded shaft 515 drives the plunger 514 to reset and move, pulling one end of the plunger 514 out of the collection hole 513. This reconnects the branch pipe 504 with the storage cavity 509, creating suction inside the storage cavity 509.

[0084] When the perforated strip 310 is wound up by the take-up roller 303, the take-up roller 303 drives the magnetic repulsion column 704 in the telescopic guide mechanism 7 to slide inside the track 306, thereby limiting the perforated strip 310.

[0085] When the magnetic repulsion column 704 moves to the bottom of the L-shaped magnetic repulsion plate 305, the magnetic repulsion force between the L-shaped magnetic repulsion plate 305 and the magnetic repulsion column 704 overcomes the supporting force of the second spring 703 on the push plate 702, causing the push plate 702 to press down the second spring 703, causing the push plate 702 to drive the magnetic repulsion column 704 to move down out of the track 306. At this time, when the take-up roller 303 takes up the perforated belt 310, it moves the guide housing 701 away from the bottom of the track 306. During this process, the telescopic guide mechanism 7 is located below the L-shaped magnetic repulsion plate 305 until it is taken up outside the take-up roller 303. At this time, it is located below the magnetic repulsion ring 304, so that the magnetic repulsion force between the push plate 702 and the magnetic repulsion ring 304 keeps the magnetic repulsion column 704 in the retracted state.

[0086] When the take-up roller 303 releases the perforated belt 310, the perforated belt 310 drives the telescopic guide mechanism 7 to move along the magnetic repulsion ring 304 and the L-shaped magnetic repulsion plate 305 to the bottom of the track 306. After the telescopic guide mechanism 7 disengages from the bottom of the L-shaped magnetic repulsion plate 305, the second spring 703 pushes the push plate 702 and the magnetic repulsion column 704 to move upward, so that the top of the magnetic repulsion column 704 is inserted into the track 306, limiting the upper and lower ends of the perforated belt 310.
