Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled machine tools, and in particular to a processing device for numerically controlled machine tools. Background Art

[0002] In the existing CNC horizontal lathe processing scenarios, when faced with the processing task of a long workpiece, it is usually necessary to use a gantry to lift the part and rely on manual operation to insert it into the workpiece feed port on one side of the lathe. However, this processing method has many limitations. On the one hand, the number of gantries equipped in the factory is often limited, which to a certain extent limits the development of long workpiece processing tasks, easily causing delays in the processing process and reduced production efficiency. On the other hand, even if the gantry can be used to place the long workpiece at the workpiece feed port, in the subsequent processing process, due to the long length of the workpiece, it is impossible to rely on the gantry for a long time to maintain its stability. When only one end of the workpiece is clamped by the triangular chuck and its center is located at the other end away from the triangular chuck, the workpiece will inevitably rotate around the clamping point during the processing. This rotation behavior will cause a series of problems, especially the workpiece has a large rotation range and covers a wide working area, which is easy to cause collision risks to surrounding personnel, equipment and other tooling and fixtures, affecting the accuracy and stability of the processing, and increasing the production cost and production cycle. Therefore, the present application provides a processing device for a CNC machine tool to meet the needs. Summary of the invention

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, the auxiliary loading component is set to realize the precise auxiliary installation and positioning of long and heavy workpieces. The coordinated operation of the bearing plate, the first screw rod and the sliding rod, as well as the adjustable function of the center frame, effectively solves the problem of long and heavy workpieces in the process of handling and loading. At the same time, the supporting frame matched therewith has height adjustability and can flexibly adapt to CNC horizontal lathes of different height specifications, which greatly enhances the versatility and compatibility of the entire loading system, reduces the dependence on the gantry, avoids the processing delay caused by the limited number of gantries, reduces the labor intensity and operation difficulty of the staff, reduces the safety risks in the process of manual handling, and further improves the safety and stability of the production process. Through the cleaning component, after placing a longer and heavier workpiece on the support frame, as the carrier plate slides upward and transports it toward the workpiece feed port of the CNC horizontal lathe, the surface of the processed workpiece can be cleaned synchronously. On the one hand, the rust on the workpiece surface caused by oxidation and other reasons can be removed with the help of the wire brush in the rotating cylinder. On the other hand, the rubber block in the rotating cylinder uses its own sticky properties to strongly adhere to the dust attached to the surface of the workpiece to ensure the removal of dust particles, thereby reducing the interference of the triangular chuck clamping performance due to rust and dust residue on the workpiece surface during the processing of the CNC horizontal lathe. Moreover, while performing the rust removal operation, lubricating oil can be automatically added to the surface of the workpiece after rust removal. When the carrier plate rises to cause the moving part to move, the lubricating structure linked thereto starts to operate. The lubricating oil in the storage tank is evenly transported to the sponge wiper through the delivery pipe under the push of the piston. The sponge wiper contacts the surface of the workpiece with appropriate pressure, so that the lubricating oil can form a uniform and moderately thick oil film on the surface of the workpiece. This oil film not only effectively reduces the friction coefficient between the workpiece and the tool during subsequent processing, reduces tool wear, and extends tool life, but also assists in removing the heat generated during processing, preventing the workpiece from deformation or performance degradation due to overheating, thereby significantly improving processing accuracy and quality, and ensuring efficient and stable operation of the entire processing process; After applying lubricating oil on the surface of the workpiece, when the workpiece arrives at the workpiece feed port, the excess lubricating oil on the surface of the workpiece is scraped off, and the scraped lubricating oil is collected. After collection, the lubricating oil is sprayed on the workpiece being processed. The scraped and collected lubricating oil is sprayed on the processing part in a targeted manner, which can ensure that there is an appropriate amount of lubricating oil in the key areas that need lubrication and heat dissipation, making the temperature distribution in the processing process more reasonable, which helps to improve the processing accuracy and surface quality.

DETAILED DESCRIPTION

[0018] The following is a detailed description of a processing device for a CNC machine tool provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0019] like Figure 1-12 As shown, an embodiment of the present invention provides a processing device for a CNC machine tool, including a CNC horizontal lathe 1 and a workpiece feed port 2 for placing a workpiece 309 in the CNC horizontal lathe 1, and a triangular chuck 3 for clamping the workpiece 309, wherein the triangular chuck 3 can firmly fix the workpiece 309 during lathe processing, and a support frame 301 is provided on one side of the CNC horizontal lathe 1, and a plurality of self-locking universal wheels 508 are equidistantly installed at the bottom of the support frame 301 to increase the mobility and flexibility of the equipment, and an auxiliary loading component 300 for assisting the loading of the workpiece 309 is installed on the support frame 301, which can facilitate the loading of longer and heavier workpieces 309 and reduce the use of the gantry.

[0020] Specifically, the auxiliary loading assembly 300 includes a carrying plate 302, which is slidably arranged on the inner wall of the supporting frame 301. The supporting frame 301 provides a stable supporting frame for the carrying plate 302. A first screw 303 is rotatably arranged on the inner wall of the supporting frame 301. The carrying plate 302 is threadedly connected to the first screw 303 through a threaded hole. At the same time, in order to ensure the stability of the carrying plate 302 during the sliding process and prevent it from rotating or deviating, a sliding rod 304 is fixedly arranged on the inner wall of the supporting frame 301. The carrying plate 302 is slidably connected to the outer wall of the sliding rod 304 through a sliding hole. A turning handle 305 is fixedly arranged on the end of the first screw 303 away from the carrying plate 302. The operator can control the rotation of the first screw 303 by turning the turning handle 305, thereby realizing the position adjustment of the carrying plate 302. The outer wall of the turning handle 305 is provided with an anti-slip sleeve to increase the friction of the hand on the turning handle 305. The surface of the carrier plate 302 is provided with a first slide groove 306, and a center frame 307 that can support the workpiece 309 during processing is slidably disposed on the inner wall of the first slide groove 306. The center frame 307 is responsible for directly contacting the workpiece 309 and providing support in the entire loading assembly. The center frame 307 can be rotated and opened and closed through a hinge. When loading the workpiece 309, the center frame 307 can be conveniently opened, and then closed after the workpiece 309 is placed, ensuring that the workpiece 309 is in a stable supporting state during the processing. The inner wall of the center frame 307 is equidistantly provided with a plurality of rotating wheels 308. When the workpiece 309 is placed in the center When the workpiece 309 is in the center frame 307 and contacts the outer wall of the rotating wheel 308, the workpiece 309 can rotate smoothly relative to the rotating wheel 308, which is particularly important for some workpieces 309 that need to be rotated during the processing. It can not only reduce the friction resistance between the workpiece 309 and the supporting structure and reduce wear, but also ensure the stability and accuracy of the workpiece 309 during the rotation process. The inner wall of the center frame 307 is slidably provided with the workpiece 309, and the workpiece 309 is rotatably connected to the outer wall of the rotating wheel 308, so that the workpiece 309 can rotate freely in the center frame 307 to meet the needs of different processing techniques; In order to further ensure that the position of the center frame 307 on the supporting plate 302 is fixed, a plurality of first limiting grooves 310 are equidistantly provided on the inner wall of the first slide groove 306, and a first latch 311 is slidably provided on the center frame 307. The first latch 311 penetrates the center frame 307 and is plugged into the first limiting groove 310. When the center frame 307 slides to the desired position in the first slide groove 306, the first latch 311 is inserted into the corresponding first limiting groove 310, so that the sliding of the center frame 307 can be effectively limited to prevent it from being displaced due to external force during the processing, thereby ensuring the accuracy and safety of the processing of the workpiece 309.

[0021] When processing a long and heavy workpiece 309, the staff first opens the center frame 307, then places the workpiece 309 on the inner wall of the center frame 307, and then rotates the pull rod equipped on the rotating wheel 308. With this operation, the rotating wheel 308 can be adaptively adjusted according to the actual size of the outer side of the workpiece 309, so as to fit closely to the surface of the workpiece 309, and achieve effective support and precise positioning of the workpiece 309. After completing the above operations, the center frame 307 is closed and fastened with bolts to ensure that the workpiece 309 remains stable during the subsequent processing. When the support position of the center frame 307 is adaptively adjusted according to the length of the workpiece 309, the first latch 311 needs to be pulled outward first to release the current limit of the center frame 307, and then the center frame 307 is pushed to slide along the inner wall of the first slide groove 306. In this process, the position of the center frame 307 can be flexibly adjusted according to the specific length of the workpiece 309. After it is determined that the center frame 307 has been adjusted to a suitable support position, the first latch 311 is passed through the center frame 307 again and inserted into the corresponding first limit groove 310, so as to achieve accurate fixation of the position of the center frame 307. Finally, by manually turning the handle 305, the rotational movement of the handle 305 will drive the first screw 303 connected thereto to rotate synchronously. Since the supporting plate 302 and the first screw 303 are threadedly connected, and the supporting plate 302 forms a sliding connection with the outer wall of the slide rod 304 through the sliding hole, under the drive of the rotation of the first screw 303, the supporting plate 302 will slide upward along the outer wall of the slide rod 304. At the same time, in the process of sliding upward along the inner wall of the support frame 301, the supporting plate 302 will drive the workpiece 309 placed thereon to slide toward the workpiece feed port 2.

[0022] like Figure 1-10 As shown, during the storage process of the workpiece 309, due to environmental factors, rust is easy to appear on its surface, and a certain amount of dust will also adhere to it. The presence of these rust and dust will have a significant negative impact on the clamping effect of the triangular chuck 3 on the workpiece 309 when the workpiece 309 is processed, because the rust will make the surface of the workpiece 309 rough and uneven, reducing the friction and fit between the triangular chuck 3, and the dust will form a gap when the workpiece 309 contacts the triangular chuck 3, hindering the close bite between the two, thereby greatly reducing the stability and reliability of the clamping, and may eventually cause the workpiece 309 to be damaged. Affecting the processing accuracy and processing quality, and even causing safety hazards, therefore, a cleaning component for cleaning the rust and dust on the surface of the workpiece 309 is also installed on the surface of the carrier plate 302, mainly in the process of the workpiece 309 rising with the carrier plate 302, the rust and dust on the surface of the workpiece 309 can be cleaned synchronously, effectively reducing the problem of unstable clamping of the triangular chuck 3 caused by rust and dust, so that the staff does not need to spend extra energy to remove rust and clean the dust on the clamping part of the triangular chuck 3 of the workpiece 309, which significantly improves the convenience and efficiency of the processing flow; like Figure 1-8As shown, further, this process also has the function of lubricating the workpiece 309. When the workpiece 309 is processed, lubrication can effectively reduce the friction coefficient between the workpiece 309 and the processing tool, reduce tool wear, and extend the service life of the tool. It also helps to reduce heat generation during the processing and prevent the workpiece 309 from being deformed or performance deteriorating due to overheating, thereby ensuring the stability of the processing accuracy and quality of the workpiece 309, and improving the reliability and economy of the entire processing technology.

[0023] Specifically, the cleaning assembly includes a second screw 312, which is rotatably mounted on the surface of the carrier plate 302. By providing a threaded hole on the second screw 312 and threading the moving member 313 therewith, when the second screw 312 rotates, the moving member 313 can achieve linear displacement on the carrier plate 302; On the inner wall of the movable part 313, a rotating cylinder 314 is rotatably arranged, and on the inner wall of the rotating cylinder 314, a plurality of wire brushes 315 and a plurality of rubber blocks 316 are equidistantly distributed. The rubber blocks 316 are usually made of a material with certain flexibility and viscosity, and the wire brush 315 and the rubber blocks 316 are in close contact with the outer wall of the workpiece 309. The wire brush 315 can effectively remove rust attached to the surface of the workpiece 309 with its hard and dense bristles, and the rubber blocks 316 can wipe away fine impurities such as dust without damaging the surface of the workpiece 309. The two cooperate with each other to comprehensively clean the surface of the workpiece 309 from different angles and strengths, ensuring that the surface of the workpiece 309 reaches an ideal cleanliness, creating good conditions for the stable clamping of the triangular chuck 3 and subsequent processing operations.

[0024] like Figure 1-10As shown, in order to realize the rotation function of the rotating cylinder 314, a sliding first rack 317 is provided on the surface of the carrying plate 302, and a first rotating rod 318 is rotatably installed on the inner wall of the moving member 313. A first gear 319 is fixed to the outer wall of the first rotating rod 318, and the first gear 319 and the first rack 317 are meshed with each other. When the moving member 313 moves on the carrying plate 302, due to the meshing relationship between the first gear 319 and the first rack 317, the first rotating rod 318 will rotate accordingly, and an active bevel gear 320 is fixedly provided at one end of the first rotating rod 318 away from the first gear 319. Correspondingly, a second rotating rod 321 is also rotatably provided on the inner wall of the moving member 313, and a second rotating rod 321 is fixed on its outer wall. The driven bevel gear 322 is meshed with the active bevel gear 320, and the rotation of the first rotating rod 318 can be smoothly transmitted to the second rotating rod 321 and change its rotation direction. The second rotating rod 321 is fixedly provided with a second gear 323 at one end away from the driven bevel gear 322, and the outer wall of the rotating cylinder 314 is fixed with a driven gear 324, and the second gear 323 is meshed with the driven gear 324. In this way, when the moving member 313 moves, under the coordinated transmission action of this series of gears and bevel gears, the rotating cylinder 314 will achieve stable rotation, so that the wire brush 315 and the rubber block 316 can rotate and wipe while contacting with the workpiece 309, further enhancing the cleaning effect; In addition, a third gear 325 is fixedly provided at one end of the second screw 312 close to the CNC horizontal lathe 1, and a second rack 326 is fixedly provided at the position of the support frame 301 close to the CNC horizontal lathe 1. The third gear 325 is meshed with the second rack 326. When the supporting plate 302 rises, the second rack 326 is displaced relative to the third gear 325, thereby driving the second screw 312 to rotate, and then driving the moving part 313 to perform corresponding moving operations on the supporting plate 302, thereby realizing the synchronous rising and cleaning actions of the workpiece 309, and effectively improving the degree of automation and continuity of the processing flow.

[0025] A storage tank 327 is fixedly installed on the surface of the movable member 313, and the storage tank 327 is specially used for storing lubricating oil. The outer wall of the storage tank 327 is connected with a filling port, and the lubricating oil can be added to the storage tank 327 through the filling port. A support plate is fixed on the outer wall of the storage tank 327, and a reciprocating screw 328 is rotatably arranged on the surface of the support plate. The reciprocating screw 328 is threadedly connected to the push plate 329 through a threaded hole. A piston 330 is slidably arranged on the inner wall of the storage tank 327, and a push rod 331 is fixedly connected to the surface of the piston 330, and the push rod 331 is fixed to the push plate 329. A collar 332 is fixedly arranged on one side of the movable member 313 close to the third rack 336, and a sponge 333 is fixed on the inner wall of the collar 332. With the push of the piston 330, the lubricating oil in the storage tank 327 will be transported to the sponge 333 through the delivery pipe 334. In the embodiment, when the workpiece 309 passes through the sponge 333, uniform lubrication of the surface of the workpiece 309 can be achieved. A fourth gear 335 is fixedly arranged at the end away from the push rod 331, and a third rack 336 is fixedly arranged on the surface of the supporting plate 302. Through the meshing relationship between the fourth gear 335 and the third rack 336, during the movement of the movable member 313, the reciprocating screw rod 328 can be driven to rotate, thereby automatically completing the pushing and applying operations of the lubricating oil, ensuring that the workpiece 309 is fully and appropriately lubricated before processing. A slide rail 507 is fixedly arranged on the surface of the supporting plate 302, and a slide hole is opened at the bottom of the movable member 313. The movable member 313 is slidably connected to the outer wall of the slide rail 507 through the slide hole, which plays an effective limiting role to prevent the movable member 313 from being unstable such as left-right deviation or shaking during the sliding process.

[0026] When the carrier plate 302 slides upward along the inner wall of the support frame 301, the second rack 326 interacts with the third gear 325, causing the third gear 325 to rotate, and the rotation of the third gear 325 is then transmitted to the second screw 312, driving it to rotate synchronously. As the second screw 312 rotates, the moving member 313 threadedly connected thereto slides linearly along the slide rail 507 toward the direction of the center frame 307; During the sliding of the moving member 313, the first rack 317 and the first gear 319 are linked, and the rotation of the first gear 319 drives the first rotating rod 318 to rotate, thereby causing the active bevel gear 320 to start rotating. The rotation of the active bevel gear 320 drives the driven bevel gear 322 to rotate through the meshing relationship, and the rotation of the driven bevel gear 322 causes the second rotating rod 321 to rotate. The rotation of the second rotating rod 321 drives the second gear 323 to operate, and the meshing of the second gear 323 and the driven gear 324 causes the driven gear 324 to rotate, and finally drives the rotating cylinder 31 4 performs a rotating motion. When the rotating cylinder 314 rotates, the wire brush 315 inside it uses its bristle structure and rigidity to vigorously brush away the rust on the surface of the workpiece 309; and the rubber block 316 uses its sticky properties to effectively stick and remove the dust attached to the surface of the workpiece 309. In this way, while the carrier plate 302 drives the workpiece 309 to move upward for subsequent installation operations, the rust and dust on the surface of the workpiece 309 are cleverly cleaned, ensuring the cleanliness of the surface of the workpiece 309, laying a good foundation for subsequent processing; As the moving member 313 continues to slide and advance toward the center frame 307, when the third rack 336 contacts the fourth gear 335, the third rack 336 exerts a toggling effect on the fourth gear 335, causing the fourth gear 335 to rotate. The rotation of the fourth gear 335 drives the reciprocating screw 328 to start rotating. The rotation of the reciprocating screw 328 causes the push plate 329 threadedly connected thereto to slide up and down along its axial direction. The up and down reciprocating motion of the push plate 329 drives the piston 330 to slide up and down on the inner wall of the storage tank 327 through the push rod 331. During the sliding process of the piston 330 in the storage tank 327, the lubricating oil in the storage tank 327 is squeezed, so that the lubricating oil is squeezed into the delivery pipe 334 and flows into the sponge 333 along the delivery pipe 334, thereby completing the lubricating oil adding operation to the sponge 333. As the moving part 313 moves further, the rotating cylinder 314 continues to clean along the surface of the workpiece 309. At the same time, the ring 332 slides along the cleaned surface of the workpiece 309 driven by the moving part 313. During this process, the sponge 333 contacts the surface of the workpiece 309. Since the lubricating oil has been injected before, the sponge 333 evenly applies the lubricating oil to the surface of the workpiece 309, thereby achieving effective lubrication of the surface of the cleaned workpiece 309. This lubrication process and cleaning process not only improves the preparation efficiency of the workpiece 309 before processing, but also effectively reduces friction loss and equipment wear during processing, thereby ensuring processing accuracy and quality.

[0027] like Figure 13-14As shown, further, when the surface of the workpiece 309 is lubricated, the friction coefficient between the workpiece 309 and the tool can be significantly reduced during the processing, the wear of the tool can be reduced, and the service life of the tool can be extended. At the same time, it helps to reduce the heat generated during the processing and prevent the workpiece 309 from being deformed or deteriorating due to overheating, thereby ensuring the stability of the processing accuracy and the reliability of the processing quality. However, if there is too much lubricating oil on the surface of the workpiece 309, on the one hand, it may cause the lubricating oil to splash around in the processing area, pollute the processing environment, and increase the cleaning cost and difficulty; on the other hand, excessive lubricating oil may form an oil film layer between the workpiece 309 and the triangular chuck 3, weakening the clamping force of the fixture on the workpiece 309, causing the workpiece 309 to loosen, move, etc. during the processing. Therefore, a scraping component 400 for scraping and reusing the lubricating oil on the surface of the workpiece 309 is fixedly provided on the side of the CNC horizontal lathe 1 close to the workpiece feed port 2.

[0028] Mainly, after the lubricating oil is applied to the surface of the workpiece 309, when the workpiece 309 arrives at the workpiece feed port 2, the excess lubricating oil on the surface of the workpiece 309 is scraped off, and the scraped lubricating oil is collected. After collection, the lubricating oil is sprayed on the workpiece 309 being processed. Scraping off excess lubricating oil can effectively prevent the lubricating oil from flowing and splashing around the processing equipment, and prevent the workpiece 309 from shifting. If there is too much lubricating oil on the surface of the workpiece 309, when the workpiece 309 is clamped by the triangular chuck 3, the excessive oil film will reduce the friction between the fixture and the workpiece 309, resulting in unstable clamping of the workpiece 309. After scraping off the excess lubricating oil, the fixture can ensure effective clamping of the workpiece 309, ensure the accuracy of the processing size, and control the processing temperature. During the processing, precise control of the amount of lubricating oil used helps to better regulate the temperature of the processing area. An appropriate amount of lubricating oil can take away part of the heat generated by the processing to prevent the workpiece 309 from overheating and deformation. The scraped and collected lubricating oil is sprayed on the processing area in a targeted manner, which can ensure that there is an appropriate amount of lubricating oil in the key areas that need lubrication and heat dissipation, making the temperature distribution in the processing process more reasonable, which helps to improve the processing accuracy and surface quality.

[0029] like Figure 1-14As shown, specifically, the scraping assembly 400 includes a fixed cylinder 401, which is fixedly arranged on one side of the CNC horizontal lathe 1 close to the workpiece feed port 2, and a scraper 402 is fixedly arranged on the inner wall of the fixed cylinder 401, and the scraper 402 is arranged in an inclined state, and a plurality of through grooves 403 are equidistantly provided on the inner wall of the fixed cylinder 401, and a storage box 404 is fixedly arranged on the side of the CNC horizontal lathe 1 close to the fixed cylinder 401, and the storage box 404 is connected to the through groove 403, and a pump body 405 is fixedly arranged on the inner wall of the storage box 404, and the input end of the pump body 405 faces the inner wall of the storage box 404, and the output end of the pump body 405 is connected to a discharge pipe 406, and the end of the discharge pipe 406 away from the pump body 405 is connected to a nozzle 407, and the nozzle 407 faces the triangular chuck 3.

[0030] When the carrier plate 302 slides to the top of its travel, in order to ensure the smooth progress of the subsequent processing flow, the workpiece 309 and the workpiece feed port 2 need to be aligned according to the actual position relationship between the workpiece feed port 2 and the workpiece 309. In this process, the pull rod equipped on the rotating wheel 308 needs to be rotated. With this operation, the friction between the rotating wheel 308 and the workpiece 309 can be effectively reduced until the rotating wheel 308 no longer exerts a limiting effect on the workpiece 309, so that the workpiece 309 can move freely to a certain extent. Next, align the workpiece 309 with the workpiece feed port 2, and push the workpiece 309 by applying appropriate external force, so that it slides slowly along the surface of the wire brush 315, the rubber block 316 and the sponge 333. When passing through these components, the surface of the workpiece 309 can be further cleaned and lubricated, and then smoothly enters the workpiece feed port 2; When the workpiece 309 enters the workpiece feed port 2 and starts to go deeper inside, it will first enter the internal space of the fixed cylinder 401. As the workpiece 309 continues to be inserted into the fixed cylinder 401, the lubricating oil attached to the outer wall of the workpiece 309 will come into contact with the scraper 402 provided on the inner wall of the fixed cylinder 401. Since the scraper 402 is arranged in a specific inclined shape, during the continuous advancement of the workpiece 309, the scraper 402 can cleverly scrape off the excess lubricating oil on the surface of the workpiece 309 by virtue of its special shape and position relationship. The scraped lubricating oil will drip into the through grooves 403 equidistantly provided on the inner wall of the fixed cylinder 401 under the guidance of gravity and the inclined surface of the scraper 402. Subsequently, the lubricating oil will slowly drip along the through groove 403 into the connected storage box 404 for storage. When the lubricating oil in the storage box 404 accumulates to a certain amount, the pump body 405 installed on the inner wall of the storage box 404 can be started. During operation, the pump body 405 will extract the lubricating oil in the storage box 404 from its output end and transport it to the inside of the connecting pipe. Finally, the lubricating oil will pass through the nozzle 407 at the end of the connecting pipe and spray to the part of the workpiece 309 being processed with appropriate pressure, thereby achieving effective lubrication and heat dissipation assistance during the processing of the workpiece 309 and ensuring the efficiency and stability of the processing process.

[0031] like Figure 3-10 As shown, on the side of the movable part 313 away from the sleeve ring 332, a collecting box 501 is provided by magnetic attraction, and the bottom of the collecting box 501 is in a sliding connection with the surface of the supporting plate 302. Its core function is that when the wire brush 315 and the rubber block 316 are cleaning the rust and dust on the surface of the workpiece 309, the cleaned impurities can be effectively collected.

[0032] The specific working process is as follows: as the movable part 313 drives the rotating cylinder 314 to rotate toward the direction of the center frame 307, the cleaned rust and dust will gradually move along the surface of the workpiece 309 toward the side where the center frame 307 is located under the action of the wire brush 315 to strongly brush away the rust and the rubber block 316 to stick to the dust. Since the collecting box 501 is located at a specific position of the movable part 313 and slides with the supporting plate 302, the cleaned rust and dust will fall into the collecting box 501, thereby realizing the centralized collection and proper treatment of the rust and dust generated during the cleaning process, avoiding them from floating around in the processing environment, effectively maintaining the cleanliness and hygiene of the working area, and also facilitating the subsequent unified cleaning and management of the cleaned impurities, reducing the adverse effects of residual impurities on the processing equipment and subsequent processing procedures, and further ensuring the stability and reliability of the entire processing flow.

[0033] like Figure 5-12 As shown, considering that during the processing, when the moving member 313 slides and rises to the highest point along the carrying plate 302, at this time, although the rust and dust of the cleaned part of the workpiece 309 have been removed, there are still uncleaned areas of the workpiece 309 that need to be further processed. For this reason, a second slide groove 502 is specially opened on the surface of the carrying plate 302, and the bottom of the first rack 317 is slidably connected to the inner wall of the second slide groove 502; A sliding bar 504 is fixedly provided on one side of the first rack 317 close to the support seat, and a plurality of second limiting grooves 505 are equidistantly provided on the inner wall of the second slide groove 502, and a second latch 506 is slidably provided on the sliding bar 504. When it is necessary to clean the uncleaned part of the workpiece 309, the second latch 506 can be first pulled out from the currently inserted second limiting groove 505 to release the position restriction of the first rack 317, and then the first rack 317 is pushed to slide along the inner wall of the second slide groove 502 until it drives the rotating cylinder 314 to move to a suitable position for effectively cleaning the uncleaned part of the workpiece 309, and finally, the second latch 506 is inserted into the corresponding second limiting groove 505 through the sliding bar 504, and the position of the first rack 317 is re-fixed to ensure that during the cleaning process, the cleaning component can stably clean rust and dust from the uncleaned area of ​​the workpiece 309.

[0034] First, by rotating the pull rod on the rotating wheel 308, the position of the rotating wheel 308 can be flexibly adjusted so that it can accurately support and effectively limit the workpiece 309 according to the actual size of the outer side of the workpiece 309. When it is necessary to process the uncleaned area on the surface of the workpiece 309, the second latch 506 is pulled out from the corresponding second limiting groove 505, and then the sliding bar 504 is pulled away from the workpiece feeding port 2. Since the sliding bar 504 is fixedly connected to the first rack 317, the first rack 317 will slide along the inner wall of the second slide groove 502 during the process of pulling the sliding bar 504; As the first rack 317 slides, its teeth will mesh with the first gear 319 again, thereby driving the first gear 319 to rotate. The rotation of the first gear 319 will drive the first rotating rod 318 to rotate synchronously, thereby prompting the active bevel gear 320 to start rotating. The meshing relationship between the active bevel gear 320 and the driven bevel gear 322 causes the driven bevel gear 322 to rotate accordingly. The rotation of the driven bevel gear 322 drives the second rotating rod 321 to rotate. The rotation of the second rotating rod 321 drives the second gear 323 to operate. The meshing of the second gear 323 and the driven gear 324 causes the driven gear 324 to rotate, and finally drives the rotating cylinder 314 to rotate. When the rotating cylinder 314 rotates, the wire brush 315 and the rubber block 316 inside it will clean the rust and dust on the uncleaned parts of the surface of the workpiece 309. After the rust and dust on the surface of the workpiece 309 are cleaned, the position of the pull rod on the rotating wheel 308 is adjusted again to change the tightness of the rotating wheel 308 so that the rotating wheel 308 releases the limiting effect on the workpiece 309. At this time, the triangular chuck 3 can clamp the cleaned workpiece 309 again to continue the subsequent processing steps; Finally, push the sliding bar 504 to reset to the initial position. During the reset process of the sliding bar 504, the first rack 317 will also return to its original position. After the first rack 317 is reset, the second latch 506 passes through the sliding bar 504 and is inserted into the corresponding second limiting groove 505, so that the position of the first rack 317 is fixed and ready for the next operation.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
