Description

Technical Field

[0001] The invention relates to the technical field of heating furnace component processing, in particular to a natural gas heating furnace component positioning processing device. Background Art

[0002] As a commonly used thermal energy equipment in the industrial field, natural gas heating furnaces use burners to mix natural gas with air and then burn them to generate high-temperature heat energy. They are widely used in the material heating and processing processes of metallurgy, chemical industry and other industries. Among them, the burner sleeve is an important component of the burner. The burner sleeve is usually composed of two columnar structures with different diameters and a frustum structure for transition between the two columnar structures. At the same time, the burner sleeve has an inner cavity and is open at both ends. The end of the large-diameter columnar structure is provided with a flange structure for fixed installation. The burner sleeve increases the outlet flow rate by shrinking the cross-sectional area, forming a high-speed jet to enhance flame stability.

[0003] The burner sleeve is usually cast from a high-temperature resistant alloy using a bottom pouring method. During the manufacturing process of the burner sleeve blank, a certain processing allowance is usually reserved on its top. After the burner sleeve blank is cast, it needs to be temporarily stored and then transferred to the cutting station for precise cutting of the top to ensure the airtightness, flame shape and thermal efficiency of the burner sleeve after installation. When cutting the burner sleeve blank, the cutting height of the cutting equipment is first adjusted according to the distance between the cutting position of the burner sleeve blank and the platform, and then the burner sleeve blank is placed on the platform of the cutting equipment, and then the burner sleeve blank is clamped and fixed by a fixture, and finally the cutting equipment is controlled to cut the top processing position of the burner sleeve blank.

[0004] However, the above-mentioned cutting process has the following problems: 1. Low cutting accuracy: When the burner sleeve is installed, the upper surface of the flange structure is the main sealing surface, and the upper surface of the flange structure is located in the non-gate area, and the surface quality is better than the bottom. However, the existing method is to cut based on the bottom of the burner sleeve blank. Since the burner sleeve blank is cast by bottom pouring, its bottom is more prone to casting defects such as gate residue and oxide layer. As a result, when the burner sleeve blank is placed on the processing platform, there may be a gap between its bottom and the processing platform, resulting in deviation in the cutting position, which in turn leads to reduced cutting accuracy of the burner sleeve blank.

[0005] 2. Unstable clamping: During storage and transportation, the burner sleeve blank may have granular impurities such as molding sand particles or metal debris attached to its surface, resulting in uneven contact between the fixture and the surface of the burner sleeve blank, which in turn causes uneven distribution of the clamping force of the fixture on the burner sleeve blank, reducing the clamping stability of the burner sleeve blank.

DETAILED DESCRIPTION

[0029] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0030] See Figure 1 and Figure 8 A natural gas heating furnace component positioning and processing device includes a workbench 1, a cutting unit 2 is installed on the workbench 1, a driving unit 3 is installed in the middle of the upper side of the workbench 1, a clamping unit 4 for clamping the burner sleeve is installed on the driving unit 3, the driving unit 3 is used to drive the clamping unit 4 to rotate and move to the left, and a positioning unit 5 is installed on the clamping unit 4.

[0031] It should be noted that the cutting unit 2 adopts existing technology, which includes a mounting frame, a control system and a cutting blade. The height of the cutting blade is adjusted by the control system, and the cutting blade is driven to cut the burner sleeve by starting the control system.

[0032] The present invention is used for accurately cutting a burner sleeve blank. The present invention uses the upper surface of the flange structure of the burner sleeve blank for positioning, and uses the upper surface of the flange structure as a reference to position the cutting position of the burner sleeve blank, thereby increasing the cutting accuracy of the burner sleeve blank. At the same time, before clamping the burner sleeve blank, the present invention cleans the particulate impurities attached to the surface of the burner sleeve blank by scraping, thereby increasing the clamping stability of the burner sleeve blank.

[0033] Specifically, first adjust the cutting blade height of the cutting unit 2 so that the distance between the cutting blade and the machining reference surface of the positioning unit 5 is equal to the distance between the cutting position of the burner sleeve blank and the upper surface of its flange structure, then place the burner sleeve blank in the clamping unit 4, and place the burner sleeve blank on the positioning unit 5, and then start the clamping unit 4. The clamping unit 4 first uses a scraping method to clean the granular impurities on the surface of the burner sleeve blank corresponding to the clamping area, and then elastically clamps the burner sleeve blank and vertically calibrates it so that the burner sleeve blank is arranged vertically. Subsequently, the clamping unit 4 drives the positioning unit 5 to position it with the upper surface of the flange structure of the burner sleeve blank as a reference, so that the upper surface of the flange structure of the burner sleeve blank is aligned with the machining reference surface of the positioning unit 5, and then the cutting blade position of the cutting unit 2 is aligned with the burner sleeve blank cutting position with the upper surface of the flange structure of the burner sleeve blank as a reference, and finally the clamping unit 4 rigidly clamps the burner sleeve blank.

[0034] After the clamping unit 4 rigidly clamps the burner sleeve blank, the driving unit 3 is controlled to drive the burner sleeve blank clamped by the clamping unit 4 to move to the left, so that the burner sleeve blank moves to the left to the corresponding position of the cutting blade of the cutting unit 2, and then the driving unit 3 is controlled to drive the clamping unit 4 and the clamped burner sleeve blank to rotate, and at the same time, the cutting blade of the cutting unit 2 is started to cut the burner sleeve blank. By controlling the driving unit 3 to drive the burner sleeve blank clamped by the clamping unit 4 to slowly feed to the left, the precise cutting of the burner sleeve blank is completed. When the cutting of the burner sleeve blank is completed, the clamping unit 4 is controlled to no longer clamp the burner sleeve blank, and then the processed burner sleeve blank is taken out from the clamping unit 4.

[0035] See Figure 1 、 Figure 2 and Figure 3 The clamping unit 4 includes a rotating plate 41 arranged on the driving unit 3, and a plurality of circumferentially evenly arranged synchronous plates 43 are radially slidably installed on the rotating plate 41 through a synchronous group 42. The synchronous group 42 is used to drive the synchronous plates 43 to move synchronously. The upper parts of the opposite sides of the plurality of synchronous plates 43 are all installed with arc-shaped clamping blocks 45 through a positioning locking group 44. The positioning locking group 44 is used to cooperate with the arc-shaped clamping block 45 to vertically align the burner sleeve blank and then receive rigid clamping. A cleaning group 46 is installed on the arc-shaped clamping block 45, and the cleaning group 46 uses a scraping method to clean the particulate impurities on the surface of the burner sleeve blank corresponding to the arc-shaped clamping block 45.

[0036] See Figure 1 、 Figure 2 、 Figure 3 and Figure 8The positioning unit 5 includes an arc-shaped positioning plate 51 arranged at the lower part of the opposite sides of multiple synchronous plates 43, and the arc-shaped positioning plate 51 is connected to the corresponding synchronous plate 43 through a pressing group 52; the positioning unit 5 also includes a top extension group 53 elastically installed in the middle of the upper end of the rotating plate 41, and the pressing group 52 drives the arc-shaped positioning plate 51 to move downward, so that the arc-shaped positioning plate 51 and the top extension group 53 are coordinated with the upper surface of the flange structure of the burner sleeve blank for positioning.

[0037] See Figure 1 、 Figure 2 and Figure 3 The driving unit 3 includes a feed plate 31 that is slidably mounted on the workbench 1 left and right, a hydraulic cylinder 32 is connected between the left side of the feed plate 31 and the workbench 1, a rotating plate 41 is rotatably mounted on the middle part of the upper side of the feed plate 31, a gear ring 411 is fixedly mounted on the outer side of the rotating plate 41, and a gear 33 is meshed with the right side of the gear ring 411. The gear 33 is rotatably connected to the feed plate 31, and the gear 33 is fixedly connected to the output shaft of the motor 34 fixedly mounted on the feed plate 31.

[0038] See Figure 1 、 Figure 2 、 Figure 3 and Figure 8 , the clamping unit 4 is used to clamp and fix the burner sleeve blank, and the positioning unit 5 is used to position the upper surface of the burner sleeve blank flange structure; specifically, first place the burner sleeve blank on the opposite sides of the multiple arc-shaped clamping blocks 45, and place the burner sleeve blank in the center on the top extension group 53, and then control the synchronization group 42 to drive the multiple synchronization plates 43 to move inward synchronously, and the synchronization plate 43 drives the multiple arc positioning plates 51 to move inward synchronously through the pressing group 52, and the synchronization plate 43 drives the multiple arc-shaped clamping blocks 45 to move inward synchronously through the calibration locking group 44, and the arc-shaped clamping blocks 45 drive the cleaning group 46 to move inward synchronously. The cleaning group 46 uses a scraping method to clean the sand particles, metal debris and other granular impurities adsorbed on the surface of the burner sleeve blank, thereby cleaning the surface of the burner sleeve blank corresponding to the clamping area of the arc-shaped clamping block 45, thereby ensuring that the subsequent clamping force of the arc-shaped clamping block 45 on the burner sleeve blank is evenly distributed, and increasing the rigid clamping stability of the arc-shaped clamping block 45. Then, under the action of the calibration locking group 44, the arc-shaped clamping block 45 is elastically clamped on the outside of the burner sleeve blank, and the burner sleeve blank is vertically arranged under the elastic clamping action of the arc-shaped clamping block 45, ensuring that the cut of the burner sleeve blank is smooth.

[0039] Subsequently, the synchronous plate 43 drives multiple arc-shaped positioning plates 51 through the pressing group 52 to elastically clamp the burner sleeve blank. As the multiple synchronous plates 43 continue to move inward synchronously, the pressing group 52 drives the arc-shaped positioning plates 51 to move downward for a distance. The arc-shaped positioning plates 51 first move downward relative to the burner sleeve blank to the upper surface of the flange structure of the burner sleeve blank, and then the arc-shaped positioning plates 51 press the burner sleeve blank downward through the flange structure of the burner sleeve blank. At the same time, the extension group 53 is pressed by the burner sleeve blank and also moves downward synchronously.

[0040] When the arc positioning plate 51 moves to the lower limit position, the lower surface of the arc positioning plate 51 is the processing reference surface. Under the elastic force of the top extension group 53, the upper surface of the flange structure of the bottom of the burner sleeve blank is always in contact with the lower surfaces of multiple arc positioning plates 51, so that the upper surface of the flange structure of the burner sleeve blank is aligned with the processing reference surface, thereby achieving accurate positioning of the upper surface of the flange structure of the burner sleeve blank. Before cutting the burner sleeve blank, the height of the cutting blade of the cutting unit 2 is adjusted to make the distance between the cutting blade and the processing reference surface of the arc positioning plate 51 equal to the distance between the burner sleeve blank cutting position and the upper surface of its flange structure, so that the cutting blade position of the cutting unit 2 is accurately aligned with the burner sleeve blank cutting position based on the upper surface of the burner sleeve blank flange structure, thereby ensuring the cutting accuracy of the burner sleeve blank. Finally, the arc clamping block 45 rigidly clamps the burner sleeve blank under the action of the calibration locking group 44.

[0041] After the arc-shaped clamping block 45 rigidly clamps the burner sleeve blank, the hydraulic cylinder 32 is controlled to drive the burner sleeve blank to move to the left to the position corresponding to the cutting blade of the cutting unit 2 through the feed plate 31, and then the motor 34 drives the rotating plate 41 to rotate through the gear 33 and the ring gear 411, so that the rotating plate 41 drives the burner sleeve blank to rotate, and at the same time controls the cutting blade of the cutting unit 2 to cut the burner sleeve blank, and controls the hydraulic cylinder 32 to drive the burner sleeve blank to feed slowly to the left through the feed plate 31 to complete the precise cutting of the burner sleeve blank. After the cutting of the burner sleeve blank is completed, the synchronization group 42 is controlled to drive multiple synchronization plates 43 to move synchronously in the direction away from each other to the initial position, so that the arc-shaped clamping block 45 and the arc-shaped positioning plate 51 no longer clamp the burner sleeve blank, and then the burner sleeve blank after processing is taken out.

[0042] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4A ring-shaped mounting groove is provided on the rotating plate 41, and the synchronization group 42 includes a plurality of circumferentially evenly arranged synchronization slides 421 radially slidably mounted on the upper side of the rotating plate 41, and the synchronization plate 43 is fixedly mounted on the upper end of the corresponding synchronization slide 421. A synchronization rod 422 is fixedly mounted on the lower end of the synchronization slide 421, and the lower end of the synchronization rod 422 slides through the mounting groove. The synchronization group 42 also includes an adjustment plate 424 rotatably mounted in the mounting groove through a rotating member 423, and an inclined hole is provided on the adjustment plate 424 at a position corresponding to the synchronization rod 422, and the synchronization rod 422 is slidably mounted in the corresponding inclined hole.

[0043] It should be noted that the rotating part 423 is an annular electric slider, which adopts the existing technology. The annular electric slider includes an annular slide rail and multiple electric sliders evenly arranged circumferentially. The annular slide rail is fixedly mounted on the annular inner wall of the mounting groove, and the electric slider is slidably mounted on the inner annular surface of the annular slide rail, and the electric slider is fixedly mounted on the outer annular surface of the adjustment plate 424. By starting the electric slider to slide along the annular slide rail, the electric slider drives the adjustment plate 424 to rotate with its axis as the reference.

[0044] The synchronization group 42 is used to drive multiple synchronization plates 43 to move synchronously inward and outward; specifically, the starting rotating member 423 drives the adjustment plate 424 to rotate, and the adjustment plate 424 drives multiple synchronization rods 422 to move synchronously inward and outward through the inclined hole, and the synchronization rod 422 drives multiple synchronization plates 43 to move synchronously inward and outward through the synchronization slide 421.

[0045] See Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The cleaning group 46 includes an inclined plate 461 hinged on the upper and lower sides of the arc-shaped clamping block 45 through a torsion spring axis 1, and the torsion spring axis 1 is located on the side of the arc-shaped clamping block 45 away from the axis of the rotating plate 41. The two inclined plates 461 form an eight-shaped structure with the large-diameter end facing the axis of the rotating plate 41. The end of the inclined plate 461 away from the torsion spring axis 1 is hinged with a square plate 462 through a torsion spring axis 2. The upper and lower ends of the square plate 462 are fixedly installed with V-shaped cleaning plates 464 through multiple connecting rods 463; the V-shaped cleaning plates 464 are arranged in an inverted V shape, and the two V-shaped cleaning plates 464 on the opposite sides of the upper and lower square plates 462 are in contact with each other. The side of the V-shaped cleaning plate 464 close to the axis of the rotating plate 41 is made of rubber and has an arc-shaped concave surface.

[0046] The cleaning group 46 is used to clean the surface of the burner sleeve blank by scraping; specifically, when the multiple arc-shaped clamping blocks 45 move inward synchronously, the arc-shaped clamping blocks 45 eventually drive the V-shaped cleaning plate 464 to move in the direction close to the burner sleeve blank through the inclined plate 461. When the V-shaped cleaning plate 464 begins to contact the surface of the burner sleeve blank, the arc-shaped concave surface of the V-shaped cleaning plate 464 can adaptively fit the surface of the burner sleeve blank. As the multiple arc-shaped clamping blocks 45 continue to move inward synchronously, under the action of the inclined plate 461, the torsion spring shaft one and the torsion spring shaft two, the upper and lower square plates 462 move synchronously away from each other, and the square plate 462 drives the V-shaped cleaning plate 464 to move synchronously through the connecting rod 463. The V-shaped cleaning plate 464 continues to move in contact with the surface of the burner sleeve blank to scrape off impurity particles such as molding sand particles and metal debris on the surface of the burner sleeve blank.

[0047] The two V-shaped cleaning plates 464 on the opposite sides of the upper and lower square plates 462 are arranged in contact with each other to ensure that the surface of the burner sleeve blank corresponding to the clamping area of the arc-shaped clamping block 45 is thoroughly cleaned. At the same time, since the V-shaped cleaning plates 464 are arranged in an inverted V shape, when the scraped sand particles, metal debris and other impurity particles fall downward, the impurity particles can fall downward along the upper V-shaped surface of the V-shaped cleaning plates 464, preventing the scraped impurity particles from falling again onto the cleaned burner sleeve blank surface, further ensuring the arc clamping The surface of the burner sleeve blank corresponding to the clamping area of the holding block 45 is flat, thereby further ensuring the stability of the arc-shaped clamping block 45 when clamping the surface of the burner sleeve blank. When the upper and lower square plates 462 move to the opposite sides to the extreme position, the arc-shaped clamping block 45 begins to clamp the burner sleeve blank. When the cutting of the burner sleeve blank is completed and multiple arc-shaped clamping blocks 45 move outward synchronously, under the action of the inclined plate 461, torsion spring shaft one and torsion spring shaft two, the upper and lower square plates 462 move synchronously to the opposite sides to the initial position.

[0048] See Figure 2 、 Figure 3 and Figure 5 The calibration locking group 44 includes an elastic clamping rod 441 fixedly mounted on the opposite side of the arc-shaped clamping block 45. The end of the elastic clamping rod 441 away from the arc-shaped clamping block 45 is radially slidably connected to its corresponding synchronization plate 43, and two symmetrically arranged locking grooves are provided on the elastic clamping rod 441.

[0049] See Figure 5 The calibration locking group 44 also includes two symmetrically arranged elastic locking rods 442 slidably installed on the synchronization plate 43. The opposite ends of the elastic locking rods 442 are simultaneously in contact with the corresponding elastic pressing rods 441. The opposite ends of the elastic locking rods 442 and the side away from the axis of the rotating plate 41 are set as inclined surfaces. When the elastic pressing rod 441 is compressed a certain distance, the locking groove is used to cooperate with the corresponding elastic locking rod 442 to automatically lock the elastic pressing rod 441.

[0050] See Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The calibration locking group 44 cooperates with the arc-shaped clamping block 45 to ensure that the burner sleeve is rigidly clamped after vertical calibration; specifically, when the multiple synchronous plates 43 move inward synchronously, the synchronous plate 43 drives the multiple arc-shaped clamping blocks 45 to move inward synchronously through the elastic clamping rod 441. When the arc-shaped clamping block 45 clamps the burner sleeve blank and the synchronous plate 43 continues to move, the elastic clamping rod 441 is compressed. As the compression of the elastic clamping rod 441 increases, the clamping force of the multiple arc-shaped clamping blocks 45 on the burner sleeve blank gradually increases, ensuring that the burner sleeve blank is arranged vertically, which is conducive to increasing the cutting accuracy of the burner sleeve blank. When the locking groove moves to the corresponding elastic clamping groove, the burner sleeve blank is clamped. When the elastic locking rod 442 is in the position, the elastic locking rod 442 is inserted into the locking groove under the action of its elastic force, thereby locking the position of the elastic clamping rod 441, so that the arc clamping block 45 rigidly clamps the burner sleeve blank, ensuring the stability of the burner sleeve blank during cutting. When the multiple synchronization plates 43 move away from each other to the initial position, the arc clamping block 45 moves to the initial position under the action of the rebound force of the elastic clamping rod 441. During this period, the groove wall of the locking groove will push the elastic locking rod 442 to reset through the inclined surface of the elastic locking rod 442, so the elastic locking rod 442 will not hinder the elastic clamping rod 441 from moving and resetting.

[0051] See Figure 2 and Figure 3 The down-pressing group 52 includes a give-way plate 521 which is slidably mounted on the synchronous plate 43. An elastic transmission rod 522 is radially slidably mounted on the side of the give-way plate 521 close to the axis of the rotating plate 41. The arc-shaped positioning plate 51 is fixedly mounted on the end of the corresponding elastic transmission rod 522 close to the axis of the rotating plate 41. The end of the elastic transmission rod 522 away from the axis of the rotating plate 41 radially slides through the give-way plate 521 and is fixedly mounted with two symmetrically arranged down-pressing rods 523.

[0052] See Figure 2 and Figure 3 The synchronization group 42 also includes two symmetrically arranged matching plates 425 fixedly installed on the upper end of the synchronization slide 421. Matching holes 426 are opened on the matching plates 425. The matching holes 426 are arranged upwardly tilted at one end close to the axis of the rotating plate 41, and the matching holes 426 are arranged horizontally at one end away from the axis of the rotating plate 41. The lower pressure rod 523 is slidably installed in the corresponding matching hole 426.

[0053] See Figure 2 and Figure 3The extension group 53 includes a plurality of circumferentially evenly arranged extension plates 531 slidably mounted on the middle portion of the upper end of the rotating plate 41 , and the lower end of the extension plate 531 is connected to the rotating plate 41 through a plurality of extension springs 532 .

[0054] See Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 8 The pressing group 52 is used to drive the arc-shaped positioning plate 51 to move downward, so that the arc-shaped positioning plate 51 and the top extension group 53 cooperate to position the upper side of the flange structure of the burner sleeve blank; specifically, when the burner sleeve blank is cut, the burner sleeve blank is placed on the top extension plate 531, and multiple top extension plates 531 are arranged in a circumferentially uniform manner to support the burner sleeve blank. When the multiple synchronous plates 43 move inward synchronously, the synchronous plates 43 drive the multiple arc-shaped positioning plates 51 through the elastic transmission rod 522. 1 moves inward synchronously. When the arc-shaped clamping block 45 elastically clamps the burner sleeve blank, the arc-shaped positioning plate 51 starts to clamp the burner sleeve blank. As the synchronous plate 43 continues to move, the elastic transmission rod 522 is compressed, and the elastic transmission rod 522 drives the pressing rod 523 to move to the side away from the axis of the rotating plate 41. The pressing rod 523 cooperates with the inclined section of the matching hole 426 to drive the elastic transmission rod 522 to move downward. The elastic transmission rod 522 drives the yield plate 521 and the arc-shaped positioning plate 51 to move downward.

[0055] The arc positioning plate 51 first moves downward relative to the burner sleeve blank to the upper surface of the flange structure of the burner sleeve blank, and then the arc positioning plate 51 drives the burner sleeve blank to move downward through the flange structure of the burner sleeve blank, and the burner sleeve blank drives the top extension plate 531 to move downward and compress the top extension spring 532. When the lower pressure rod 523 moves to the horizontal section of the matching hole 426, the arc positioning plate 51 moves to the lower limit position. At the same time, the top extension plate 531 elastically resists the burner sleeve blank upward under the action of the top extension spring 532, and multiple top extension plates 531 are arranged circumferentially at intervals to ensure that the burner sleeve blank flange is always in contact with the lower surfaces of multiple arc positioning plates 51 under the top extension action of multiple top extension plates 531, so that the upper surface of the burner sleeve blank flange structure is aligned with the processing reference plane, thereby achieving precise positioning of the upper surface of the burner sleeve blank flange structure and increasing the cutting processing accuracy of the burner sleeve blank.

[0056] When the arc-shaped positioning plate 51 moves to the lower limit position, the arc-shaped clamping block 45 begins to rigidly clamp the burner sleeve blank. At the same time, multiple arc-shaped positioning plates 51 also clamp the flange structure of the burner sleeve blank, further ensuring the clamping stability of the burner sleeve blank. When the multiple synchronization plates 43 move away from each other to the initial position, the arc-shaped positioning plate 51 resets to the initial position under the action of the rebound force of the elastic transmission rod 522.

[0057] See Figure 2 、 Figure 3 、 Figure 7 and Figure 8 A V-shaped debris-blocking plate 431 is arranged in the middle of the opposite sides of multiple synchronous plates 43, and the tip of the V-shaped debris-blocking plate 431 is facing upward. The side of the V-shaped debris-blocking plate 431 away from the axis of the rotating plate 41 is radially slidably connected to the corresponding synchronous plate 43 through multiple elastic yielding rods 432. The side of the V-shaped debris-blocking plate 431 close to the axis of the rotating plate 41 is also made of rubber and has an arc-shaped concave surface.

[0058] When the multiple synchronous plates 43 move inward synchronously, the synchronous plates 43 drive the multiple V-shaped debris baffles 431 to move inward synchronously through the elastic yielding rods 432. When the V-shaped cleaning plates 464 begin to contact the surface of the burner sleeve blank, the V-shaped debris baffles 431 also begin to contact the surface of the burner sleeve blank. Under the action of the rubber material of the V-shaped debris baffles 431, its arc-shaped concave surface can adaptively fit on the surface of the burner sleeve blank. When the granular impurities scraped off by the V-shaped cleaning plates 464 fall downward, due to the V-shaped debris baffles The tip of the plate 431 is facing upward, that is, it is arranged upside down, and the granular impurities fall onto the upper inclined surface of the V-shaped debris baffle plate 431, and slide downward along the upper inclined surface of the V-shaped debris baffle plate 431 to separate from the V-shaped debris baffle plate 431, so that the granular impurities will not fall onto the flange structure of the burner sleeve blank in the corresponding area of the arc-shaped positioning plate 51, ensuring that the upper surface of the flange structure of the burner sleeve blank in contact with the arc-shaped positioning plate 51 is flat, further ensuring the accurate positioning of the burner sleeve blank, thereby further improving the cutting processing accuracy of the burner sleeve blank.

[0059] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
