Description

Technical Field

[0001] The invention belongs to the technical field of spiral blade welding, and in particular relates to a spiral blade welding device for a spiral auger. Background Art

[0002] Spiral blade welding Due to the special shape of the spiral blade, the material should be considered first when welding. Different materials, such as carbon steel, stainless steel, etc., will have different welding methods and material selections. For example, carbon steel spiral blade welding may use ordinary arc welding, while stainless steel spiral blades are more suitable for argon arc welding to prevent the weld from being oxidized and rusted.

[0003] In terms of welding technology, manual welding is more common for small spiral blades. When welding, the appropriate welding angle should be maintained so that the welding rod or welding gun forms a certain angle with the surface of the spiral blade, so that the welding pool can be well formed. In addition, the welding speed should be uniform. Too fast may lead to poor fusion of the weld, and too slow will make the weld too thick.

[0004] For large spiral blades, automatic welding equipment can play an advantage. These devices can more accurately control welding parameters such as welding current, voltage, welding speed, etc. Moreover, the use of automated equipment can ensure the stability of weld quality and reduce welding defects caused by human factors.

[0005] However, for large spiral blades, it is necessary to control the spiral blades and the weldment to rotate at a uniform speed in the circumferential direction during welding. Since large spiral blades are heavy, a large power is required to rotate them during the welding process. In addition, in order to improve the welding effect, the spiral blades need to rotate at a uniform and stable speed, which places high requirements on the fixing and driving mechanism of the spiral blades.

[0006] In addition, during the welding process, because the large spiral blades are large and tall, the smoke generated by welding cannot be effectively discharged, which can easily cause air pollution in the workshop.

[0007] The present invention designs a spiral auger spiral blade welding equipment to solve the above problems. Summary of the invention

[0008] Based on this, it is necessary to provide a spiral blade welding equipment to address the problems existing in the current spiral blade welding. During welding, the welding device is controlled to rotate circumferentially around the large spiral blade, while the large spiral blade and the welded part are fixed and stationary. On the one hand, this can solve the problems of poor welding stability and poor welding effect caused by the circumferential rotation of the large spiral blade; on the other hand, since there is no need to control the circumferential rotation of the large spiral blade and the welded part, there is no need to consider the problem of driving the large spiral blade to rotate, thereby reducing costs.

[0036] As Figure 1 - As Figure 15 shown, a spiral blade welding equipment for a spiral reamer includes a base 1, as Figure 1 , 2 shown, a three-jaw chuck 2 is installed above the base 1, and a power mechanism capable of driving the three-jaw chuck 2 to rotate is installed inside the base 1; two symmetrically distributed mounting pillars 3 are fixedly installed on the upper side of the base 1, and a fixing plate 6 is fixedly installed on the upper sides of the two mounting pillars 3; a top head 5 is installed on the lower side of the fixing plate 6, and the axis of the top head 5 is collinear with the axis of the three-jaw chuck 2; a welding fume extraction assembly 4, as Figure 6 , 7 , 8, 9 shown, the welding fume extraction assembly 4 includes an outer fixed arc plate 412, an inner sliding arc plate 413, a welding device 414, a square fume extraction head 415, a first motor 401, and a second motor 406. Among them, the outer fixed arc plate 412 is a semi-circular arc plate, and the outer fixed arc plate 412 is slidably installed up and down on the two mounting pillars 3, and the axis of the outer fixed arc plate 412 coincides with the axis of the three-jaw chuck 2; as Figure 1 , 2 , 6 shown, a second motor 406 capable of controlling the up and down sliding of the outer fixed arc plate 412 is installed on the base 1; as Figure 6 , 11As shown, the inner sliding arc plate 413 is a semi-circular arc plate, and the inner sliding arc plate 413 is rotatably installed inside the outer fixed arc plate 412; as Figure 2 , 6 , 11 shown, a first motor 401 capable of controlling the circumferential rotation of the inner sliding arc plate 413 relative to the outer fixed arc plate 412 is fixedly installed on the fixing plate 6; as Figure 6 , 7 , 11 shown, a welding device 414 and a square smoking head 415 are fixedly installed on the inner sliding arc plate 413.

[0037] In the present invention, the first motor 401 can control the circumferential rotation of the inner sliding arc plate 413 relative to the outer fixed arc plate 412, so as to realize the circumferential rotation of the welding device 414 and the square smoking head 415 fixedly installed on the inner sliding arc plate 413 around the welded spiral blade and the intermediate rotating shaft; at the same time, the second motor 406 can control the up and down sliding of the inner sliding arc plate 413 on which the welding device 414 and the square smoking head 415 are installed relative to the mounting column 3; that is, in the present invention, the first motor 401 and the second motor 406 can control the welding device 414 and the square smoking head 415 to rotate circumferentially around the axis of the welded spiral blade and also slide up and down, so as to realize the welding operation when the welded spiral blade and the intermediate rotating shaft are stationary. In this way, on the one hand, the problem of poor welding stability and poor welding effect caused by the circumferential rotation of the large spiral blade can be solved; on the other hand, since it is not necessary to control the circumferential rotation of the large spiral blade and the welded parts, there is no need to consider the problem of driving the large spiral blade to rotate, thus reducing the cost.

[0038] In the present invention, during the process of the welding device 414 rotating circumferentially around the welded spiral blade and the intermediate rotating shaft for welding, the square smoking head 415 will also rotate together with the welding device 414, and during the rotation, it can closely adhere to the welding point to timely absorb and process the smoke generated by welding.

[0039] In the present invention, the lower ends of the welded intermediate rotating shaft and the spiral blade will be fixed by the three-jaw chuck 2 during welding, and the upper ends are abutted against the top head 5. The welded intermediate rotating shaft and the spiral blade can be fixed by the three-jaw chuck 2 and the top head 5; however, a power mechanism capable of controlling the rotation of the three-jaw chuck 2 is installed inside the base 1 of the present invention, and the power mechanism can drive the welded intermediate rotating shaft and the spiral blade to rotate through the three-jaw chuck 2; that is, the present invention also has another welding method, that is, controlling the rotation of the intermediate rotating shaft and the spiral blade, and the welding device 414 and the square smoking head 415 slide up and down, so that welding can also be realized; and in this welding method, the square smoking head 415 is always located near the welding device 414, and can also timely absorb and process the smoke generated by welding during the welding process.

[0040] In a further embodiment, asFigure 1 , 2 As shown in FIGS. 6, a first arc-shaped rack 403 is fixedly installed on the upper side of the inner sliding arc plate 413. Two first motors 401 are symmetrically and fixedly installed on the lower side of the fixed plate 6. Two first gears 402 are fixedly installed on the output shafts of the two first motors 401. The two first gears 402 are engaged with the first arc-shaped rack 403.

[0041] When the first motor 401 operates, it can drive the first gear 402 to rotate. The rotation of the first gear 402 drives the first arc-shaped rack 403 to slide. The first arc-shaped rack 403 drives the inner sliding arc plate 413 to rotate circumferentially relative to the outer fixed arc plate 412. The reason for designing two first motors 401 is to ensure the continuity of the driving of the first arc-shaped rack 403 without any pause.

[0042] In a further embodiment, as shown in FIGS. Figure 2 , 3 6, a mounting plate 404 is slidably installed between the two mounting struts 3 through two connection blocks 411. As shown in FIG. Figure 8 , the outer fixed arc plate 412 is fixedly installed on the mounting plate 404. As shown in FIGS. Figure 3 , 4 5, two first rotating shafts 410 are respectively installed up and down on the inner side of each mounting strut 3. A transmission wheel 409 is fixedly installed on each of the two first rotating shafts 410. The two transmission wheels 409 are drivingly connected by a transmission belt 405. The transmission belt 405 is fixedly connected to the mounting plate 404 through the connection block 411. A third gear 408 is fixedly installed on the corresponding first rotating shaft 410 of the transmission wheel 409 located on the lower side. Two second motors 406 are symmetrically and fixedly installed on the upper side of the base 1. A second gear 407 is fixedly installed on the output shaft of each of the two second motors 406. The two second gears 407 correspond to and are engaged with the two third gears 408 one by one.

[0043] In the present invention, when the second motor 406 is controlled to operate, the second motor 406 drives the second gear 407 to rotate. The rotation of the second gear 407 drives the corresponding third gear 408 to rotate. The rotation of the third gear 408 drives the corresponding first rotating shaft 410 to rotate. The rotation of the first rotating shaft 410 drives the corresponding transmission wheel 409 to rotate. The rotation of the transmission wheel 409 drives the corresponding transmission belt 405 to rotate. The rotation of the transmission belt 405 drives the fixed plate 6 to slide up and down relative to the two mounting struts 3. The sliding of the fixed plate 6 drives the outer fixed arc plate 412 to slide. The outer fixed arc plate 412 drives the inner sliding arc plate 413 to slide. The sliding of the inner sliding arc plate 413 drives the welding device 414 and the square cigarette lighter 415 mounted thereon to slide up and down.

[0044] In a further embodiment, as shown in FIG. Figure 13As shown, a second installation groove 430 is formed on the inner wall at the upper end of the outer fixing arc plate 412, and a circular hole 437 penetrating through the outer fixing arc plate 412 and the rear end of the mounting plate 404 is formed in the second installation groove 430; as Figure 11 , 12 As shown, a first installation groove 427 is formed on the inner wall at the upper end of the inner sliding arc plate 413, and square openings 426 penetrating through the back surface of the inner sliding arc plate 413 are formed at both ends of the first installation groove 427; as Figure 6 , 7 , 8, 11, 12 shown, the first conductive sheet 417 is fixedly installed in the first installation groove 427, two conductive blocks 419 are fixedly installed in the two square openings 426, and the two conductive blocks 419 are in contact connection with both ends of the first conductive sheet 417; the second conductive sheet 418 is fixedly installed in the second installation groove 430, and during the circumferential rotation of the inner sliding arc plate 413 relative to the outer fixing arc plate 412, the second conductive sheet 418 will be in contact connection with one of the two conductive blocks 419, and the other unconnected conductive block 419 is in a disconnected state from the second conductive sheet 418; a wire 416 is fixedly installed on the back surface of the second conductive sheet 418, and the wire 416 passes through the circular hole 437 and is connected to an external power supply; the welding device 414 is electrically connected to the first conductive sheet 417.

[0045] Through the first conductive sheet 417, the second conductive sheet 418 and the conductive block 419, it can be ensured that during the circumferential rotation of the inner sliding arc plate 413 relative to the outer fixing arc plate 412, the first conductive sheet 417 can always be powered on and can always provide power for the welding device 414; during the circumferential rotation of the inner sliding arc plate 413 relative to the outer fixing arc plate 412, the second conductive sheet 418 will be in contact connection with one of the two conductive blocks 419, and the other unconnected conductive block 419 is in a disconnected state from the second conductive sheet 418; that is, there is always one conductive block 419 between the first conductive sheet 417 and the second conductive sheet 418 that can make the two powered on.

[0046] In a further embodiment, as Figure 13 shown, a second air chamber 431 is formed inside the lower end of the outer fixing arc plate 412, and the second air chamber 431 is connected to an external air pump through a smoking pipe 420; as Figure 13 shown, a plurality of second valve openings 432 are circumferentially and evenly formed on the inner wall at the lower end of the outer fixing arc plate 412, and the second valve openings 432 communicate with the second air chamber 431; as Figure 8 , 9 , 14, 15 shown, a first valve 421 is swingably installed at each second valve opening 432 through a second rotating shaft 433, as Figure 14 shown, elastic strips 434 are installed at both ends of the first valve 421; as Figure 10 , 14As shown, a first friction wheel 422 is fixedly installed at the lower end of the second rotating shaft 433 passing through the second air chamber 431; as Figure 6 and 8 shown in Figures 11 and 12, a first air chamber 429 is formed inside the lower end of the inner sliding arc plate 413, and the first air chamber 429 is connected to the square smoking head 415; a plurality of first valve openings 428 are evenly formed in the circumferential direction on the outer wall of the lower end of the inner sliding arc plate 413, and the first valve openings 428 communicate with the first air chamber 429; as Figure 8 and 9 shown in Figures 14 and 15, a second valve 436 is swingably installed at each first valve opening 428 through a third rotating shaft 435, as Figure 14 shown, elastic strips 434 are installed at both ends of the second valve 436; as Figure 10 and 14 shown, a second friction wheel 424 is fixedly installed at the lower end of the third rotating shaft 435 passing through the first air chamber 429; as Figure 11 shown, a first friction strip 423 is fixedly installed on the lower side of the inner sliding arc plate 413, as Figure 10 shown, the first friction strip 423 cooperates with all the first friction wheels 422; a second friction strip 425 is fixedly installed on the lower side of the outer fixed arc plate 412, and the second friction strip 425 cooperates with all the second friction wheels 424.

[0047] During the circumferential rotation of the inner sliding arc plate 413 relative to the outer fixed arc plate 412, when one end of the inner sliding arc plate 413 and the outer fixed arc plate 412 starts to coincide, the first friction strip 423 installed on the inner sliding arc plate 413 will drive the first friction wheel 422 installed on the lower side of the outer fixed arc plate 412 and starting to cooperate with it to rotate through friction, and the rotation of the first friction wheel 422 drives the corresponding first valve 421 to swing through the second rotating shaft 433, so that the corresponding second valve opening 432 is opened, as Figure 14 and 15As shown, during this process, the swinging of the first valve 421 will squeeze one of the two corresponding elastic strips 434, causing this elastic strip 434 to tightly press against the inner wall of the first air chamber 429. When the compression amount of this elastic strip 434 reaches the limit, slipping will occur between the corresponding first friction wheel 422 and the first friction strip 423; similarly, when one end of the inner sliding arc plate 413 and the outer fixed arc plate 412 begins to coincide, the second friction strip 425 installed on the outer fixed arc plate 412 will drive the rotation of the second friction wheel 424 installed on the lower side of the outer fixed arc plate 412 that starts to cooperate with it through friction. The rotation of the second friction wheel 424 drives the corresponding second valve 436 to swing through the second and third rotating shafts, causing the corresponding first valve port 428 to open; during this process, the swinging of the second valve 436 will squeeze one of the two corresponding elastic strips 434, causing this elastic strip 434 to tightly press against the inner wall of the second air chamber 431. When the compression amount of this elastic strip 434 reaches the limit, slipping will occur between the corresponding second friction wheel 424 and the second friction strip 425; in this way, the first air chamber 429 and the second air chamber 431 are made to communicate, and the square cigarette holder 415 is connected to an external air pump; when one end of the inner sliding arc plate 413 and the outer fixed arc plate 412 begins to separate, the second valve 436 installed inside the inner sliding arc plate 413 in the separated area on the inner sliding arc plate 413 will swing back under the action of the pressed elastic strip 434, causing the corresponding first valve port 428 to close, without air leakage and without affecting the smoking of the square cigarette holder 415; similarly, when one end of the outer fixed arc plate 412 and the inner sliding arc plate 413 begins to separate, the first valve 421 installed inside the outer fixed arc plate 412 in the separated area on the outer fixed arc plate 412 will swing back under the action of the pressed elastic strip 434, causing the corresponding second valve port 432 to close, without air leakage and without affecting the smoking of the square cigarette holder 415.
