Description

Technical Field

[0001] The present invention relates to the technical field of heating furnace component processing, and specifically to a positioning processing device for natural gas heating furnace components. Background Art

[0002] As a common thermal energy device in the industrial field, a natural gas heating furnace burns a mixture of natural gas and air through a burner to generate high-temperature thermal energy, which is widely used in the material heating and processing processes of industries such as metallurgy and chemical industry. Among them, the burner sleeve is an important part of the burner. The burner sleeve usually consists 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 is provided with an inner cavity and both ends are open. A flange structure for fixed installation is provided at the end of the large-diameter columnar structure. The burner sleeve improves the outlet flow rate by reducing the cross-sectional area, forming a high-speed jet to enhance the flame stability.

[0003] The burner sleeve is usually cast from a high-temperature resistant alloy by bottom casting. During the manufacturing process of the burner sleeve blank, a certain amount of machining allowance is usually reserved at the top. After the burner sleeve blank is cast, it needs to be temporarily stored, and then transferred to the cutting station for precise cutting processing at the top to ensure the airtightness, flame shape and thermal efficiency after the burner sleeve is installed. When the burner sleeve blank is currently cut and processed, first, the cutting height of the cutting equipment is adjusted according to the distance between the cutting position of the burner sleeve blank and the platform, 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. Finally, the cutting equipment is controlled to cut the processing position at the top of the burner sleeve blank.

[0004] However, the above cutting and processing process has the following problems: 1. Low cutting accuracy: Since 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, currently, the bottom of the burner sleeve blank is used as the reference for cutting. Since the burner sleeve blank is cast by bottom casting, its bottom is more likely to have casting defects such as gate residues and oxide layers, resulting in a possible gap between the bottom of the burner sleeve blank and the processing platform when it is placed on the processing platform, causing deviation of the cutting position, and thus reducing the cutting accuracy of the burner sleeve blank.

[0005] 2. Unstable clamping: Since the surface of the burner sleeve blank may be attached with particulate impurities such as molding sand particles or metal debris during storage and transportation, the contact between the fixture and the surface of the burner sleeve blank is uneven, and then the clamping force distribution of the fixture on the burner sleeve blank is uneven, reducing the clamping stability of the burner sleeve blank.

Detailed implementation manners

[0029] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those specific technologies or conditions not specified in the embodiments, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0030] Refer to Figure 1 and Figure 8 , a positioning and processing device for a natural gas heating furnace component, including 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 a 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 leftward, and a positioning unit 5 is installed on the clamping unit 4.

[0031] It should be noted that the cutting unit 2 adopts the prior art, which includes a mounting frame, a control system and a cutting blade. The height of the cutting blade is adjusted through the control system, and the control system is started to drive the cutting blade to perform cutting processing on the burner sleeve.

[0032] The present invention is used for precise cutting processing of 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 adopts a scraping method to clean the particulate impurities attached to the surface of the burner sleeve blank, increasing the clamping stability of the burner sleeve blank.

[0033] Specifically, first, adjust the height of the cutting blade of the cutting unit 2 so that the distance between the cutting blade and the processing 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 on the positioning unit 5. Next, start the clamping unit 4. The clamping unit 4 first cleans the particulate impurities on the surface of the burner sleeve blank corresponding to the clamping area by scraping, and then elastically clamps the burner sleeve blank and vertically aligns it to make the burner sleeve blank vertically arranged. Subsequently, the clamping unit 4 drives the positioning unit 5 to be positioned based on the upper surface of the flange structure of the burner sleeve blank, aligning the upper surface of the flange structure of the burner sleeve blank to the processing reference surface of the positioning unit 5. Furthermore, align the position of the cutting blade of the cutting unit 2 to the cutting position of the burner sleeve blank based on the upper surface of the flange structure of the burner sleeve blank. Finally, the clamping unit 4 rigidly clamps the burner sleeve blank.

[0034] After the clamping unit 4 rigidly clamps the burner sleeve blank, control the driving unit 3 to drive the burner sleeve blank clamped by the clamping unit 4 to move leftward, so that the burner sleeve blank moves leftward to the corresponding position of the cutting blade of the cutting unit 2. Then, control the driving unit 3 to drive the clamping unit 4 and the clamped burner sleeve blank to rotate. At the same time, start the cutting blade of the cutting unit 2 to perform cutting processing on 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 leftward, complete the precise cutting processing of the burner sleeve blank. When the cutting processing of the burner sleeve blank is completed, control the clamping unit 4 to stop clamping the burner sleeve blank, and then take out the processed burner sleeve blank from the clamping unit 4.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0036] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 8, the positioning unit 5 includes arc-shaped positioning plates 51 arranged at the lower parts on the opposite sides of a plurality of synchronous plates 43. The arc-shaped positioning plates 51 are connected to the corresponding synchronous plates 43 through a pressing group 52; the positioning unit 5 further includes a top-extending group 53 elastically installed at the middle part of the upper end of the rotating plate 41. The pressing group 52 drives the arc-shaped positioning plates 51 to move downward, so that the arc-shaped positioning plates 51 cooperate with the top-extending group 53 to position based on the upper surface of the flange structure of the burner sleeve blank.

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

[0038] Refer to 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 flange structure of the burner sleeve blank; specifically, first place the burner sleeve blank on the opposite sides of a plurality of arc-shaped clamping blocks 45 and center the burner sleeve blank on the top-extending group 53. Then control the synchronous group 42 to drive a plurality of synchronous plates 43 to move inward synchronously. The synchronous plates 43 drive a plurality of arc-shaped positioning plates 51 to move inward synchronously through the pressing group 52. The synchronous plates 43 drive a plurality of arc-shaped clamping blocks 45 to move inward synchronously through the alignment and locking group 44. The arc-shaped clamping blocks 45 drive the cleaning group 46 to first contact the surface of the burner sleeve blank. The cleaning group 46 uses a scraping method to clean the granular impurities such as molding sand particles and metal chips adsorbed on the surface of the burner sleeve blank, realizing the cleaning of the surface of the burner sleeve blank corresponding to the clamping area of the arc-shaped clamping blocks 45, thereby ensuring that the clamping force of the subsequent arc-shaped clamping blocks 45 on the burner sleeve blank is evenly distributed and increasing the rigid clamping stability of the arc-shaped clamping blocks 45. Then, under the action of the alignment and locking group 44, the arc-shaped clamping blocks 45 elastically clamp on the outer side of the burner sleeve blank, and the burner sleeve blank is vertically arranged under the elastic clamping action of the arc-shaped clamping blocks 45, ensuring that the cut of the burner sleeve blank is flat.

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

[0040] When the arc-shaped positioning plate 51 moves to the lower limit position, at this time, the lower surface of the arc-shaped positioning plate 51 is the machining reference surface. Under the elastic force of the top extension group 53 at the bottom of the blank of the burner sleeve, the upper surface of its flange structure always contacts the lower surfaces of the plurality of arc-shaped positioning plates 51, aligning the upper surface of the flange structure of the blank of the burner sleeve with the machining reference surface, realizing the precise positioning of the upper surface of the flange structure of the blank of the burner sleeve. Before cutting and processing the blank of the burner sleeve, by adjusting the height of the cutting blade of the cutting unit 2, the distance between the cutting blade and the machining reference surface of the arc-shaped positioning plate 51 is made equal to the distance between the cutting position of the blank of the burner sleeve and the upper surface of its flange structure, so that the position of the cutting blade of the cutting unit 2 is accurately aligned with the cutting position of the blank of the burner sleeve with the upper surface of the flange structure of the blank of the burner sleeve as the reference, ensuring the cutting and processing accuracy of the blank of the burner sleeve. Finally, the arc-shaped clamping block 45 rigidly clamps the blank of the burner sleeve under the action of the alignment and locking group 44.

[0041] After the arc-shaped clamping block 45 rigidly clamps the blank of the burner sleeve, control the hydraulic cylinder 32 to drive the blank of the burner sleeve to move leftward through the feed plate 31 to a position corresponding to the cutting blade of the cutting unit 2, and then the motor 34 drives the rotating plate 41 to rotate through the gear 33 and the gear ring 411, so that the rotating plate 41 drives the blank of the burner sleeve to rotate. At the same time, control the cutting blade of the cutting unit 2 to perform cutting and processing on the blank of the burner sleeve, and control the hydraulic cylinder 32 to drive the blank of the burner sleeve to feed slowly leftward through the feed plate 31 to complete the precise cutting and processing of the blank of the burner sleeve. After the cutting and processing of the blank of the burner sleeve is completed, control the synchronization group 42 to drive the plurality of 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 plates 51 no longer clamp the blank of the burner sleeve, and then take out the processed blank of the burner sleeve.

[0042] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, an annular installation groove is formed in the rotating plate 41. The synchronization group 42 includes a plurality of circumferentially uniformly arranged synchronization sliding plates 421 that are radially slidably installed on the upper side of the rotating plate 41. The synchronization plate 43 is fixedly installed at the upper end of the corresponding synchronization sliding plate 421. A synchronization rod 422 is fixedly installed at the lower end of the synchronization sliding plate 421. The lower end of the synchronization rod 422 slidably penetrates through the installation groove. The synchronization group 42 further includes an adjusting plate 424 that is rotatably installed in the installation groove through a rotating member 423. Oblique holes are formed in the adjusting plate 424 at positions corresponding to the synchronization rods 422, and the synchronization rods 422 are slidably installed in the corresponding oblique holes.

[0043] It should be noted that the rotating member 423 is an annular electric slider. The annular electric slider adopts the prior art. The annular electric slider includes an annular slide rail and a plurality of circumferentially uniformly arranged electric sliders. The annular slide rail is fixedly installed on the annular inner wall of the installation groove. The electric slider is slidably installed on the inner annular surface of the annular slide rail, and the electric slider is fixedly installed on the outer annular surface of the adjusting plate 424. By starting the electric slider to slide along the annular slide rail, the electric slider drives the adjusting plate 424 to rotate with its axis as the reference.

[0044] The synchronization group 42 is used to drive a plurality of synchronization plates 43 to move synchronously inward and outward; specifically, starting the rotating member 423 drives the adjusting plate 424 to rotate. The adjusting plate 424 drives a plurality of synchronization rods 422 to move synchronously inward and outward through the oblique holes. The synchronization rods 422 drive a plurality of synchronization plates 43 to move synchronously inward and outward through the synchronization sliding plates 421.

[0045] Refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , the cleaning group 46 includes inclined plates 461 that are hinged to the upper and lower sides of the arc-shaped clamping block 45 through a torsion spring shaft one, and the torsion spring shaft one 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 shaft one is hinged with a square plate 462 through a torsion spring shaft two. V-shaped cleaning plates 464 are fixedly installed at the upper and lower ends of the square plate 462 through a plurality of connecting rods 463; the V-shaped cleaning plates 464 are arranged in an inverted V shape. 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 material and is provided with 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 multiple arc-shaped clamping blocks 45 move inward synchronously, the arc-shaped clamping blocks 45 finally drive the V-shaped cleaning plate 464 to move towards the burner sleeve blank through the inclined plate 461. When the V-shaped cleaning plate 464 starts to contact the surface of the burner sleeve blank, the arc-shaped concave surface of the V-shaped cleaning plate 464 can adaptively fit on the surface of the burner sleeve blank. As multiple arc-shaped clamping blocks 45 continue to move inward synchronously, under the action of the inclined plate 461, the first torsion spring shaft, and the second torsion spring shaft, the upper and lower square plates 462 move away from each other synchronously. The square plates 462 drive the V-shaped cleaning plate 464 to move synchronously through the connecting rod 463. The V-shaped cleaning plate 464 continuously moves while fitting on the surface of the burner sleeve blank, scraping off impurity particles such as sand grains 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 in contact with each other to ensure thorough cleaning of the surface of the burner sleeve blank corresponding to the clamping area of the arc-shaped clamping blocks 45. At the same time, since the V-shaped cleaning plates 464 are arranged in an inverted V shape, when the scraped sand grains, 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 back onto the surface of the cleaned burner sleeve blank, further ensuring the flatness of the surface of the burner sleeve blank corresponding to the clamping area of the arc-shaped clamping blocks 45, and thus further ensuring the stability when the arc-shaped clamping blocks 45 clamp the surface of the burner sleeve blank. When the upper and lower square plates 462 move to the extreme positions on the opposite sides, at this time, the arc-shaped clamping blocks 45 start to clamp the burner sleeve blank. When the cutting process 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, the first torsion spring shaft, and the second torsion spring shaft, the upper and lower square plates 462 move towards each other synchronously to the initial positions.

[0048] Refer to Figure 2 、 Figure 3 and Figure 5 Refer to

[0049] Refer to Figure 5 Refer to , the alignment and locking group 44 includes elastic abutting rods 441 fixedly installed on the opposite sides of the arc-shaped clamping blocks 45. One end of the elastic abutting rod 441 away from the arc-shaped clamping block 45 is radially slidably connected to its corresponding synchronous plate 43. Two symmetrically arranged locking grooves are formed on the elastic abutting rod 441.

[0050] Refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 Refer to

[0051] Refer to Figure 2 and Figure 3 Refer to

[0052] Refer to Figure 2 and Figure 3 Refer to

[0053] Refer to Figure 2 and Figure 3The extension group 53 includes a plurality of extension plates 531 slidably mounted up and down in the middle of the upper end of the rotating plate 41 and arranged evenly in the circumferential direction. The lower end of the extension plate 531 is connected to the rotating plate 41 through a plurality of extension springs 532 .

[0054] See also 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 uniformly spaced 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 and the inclined section of the matching hole 426 cooperate to drive the elastic transmission rod 522 to move downward, and the elastic transmission rod 522 drives the yielding plate 521 and the arc-shaped positioning plate 51 to move downward.

[0055] The arc-shaped 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-shaped 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-shaped 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 at intervals in the circumferential direction to ensure that the upper surface of the flange structure of the burner sleeve blank is always in contact with the lower surfaces of multiple arc-shaped positioning plates 51 under the top extension action of multiple top extension plates 531, so that the upper surface of the flange structure of the burner sleeve blank is aligned with the processing reference plane, thereby realizing accurate positioning of the upper surface of the flange structure of the burner sleeve blank 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] Refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 , V-shaped impurity baffle plates 431 are arranged in the middle of the opposite sides of multiple synchronous plates 43, and the tips of the V-shaped impurity baffle plates 431 face upward. One side of the V-shaped impurity baffle 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. One side of the V-shaped impurity baffle plate 431 close to the axis of the rotating plate 41 is also made of rubber material and is provided with an arc-shaped concave surface.

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

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