Description

Aluminum bronze welding device Technical Field

[0001] The present invention relates to the technical field of welding equipment, in particular to an aluminum bronze welding device. Background Art

[0002] When welding aluminum bronze workpieces, workers typically use MIG welding, using argon as the shielding gas. This method is suitable for welding medium- to heavy-thick aluminum bronze workpieces. The weld seam is dense, with fine grains and few defects. Because aluminum bronze molten metal has high surface tension and low thermal conductivity, it can be welded in all positions. Direct current reverse polarity welding is often used.

[0003] Currently, workers working on aluminum-bronze workpieces outdoors need to build windbreaks near the weld seams to improve the outdoor welding environment. Because these windbreaks are bulky and take a long time to assemble, and they need to be built for each weld, this increases the preparation time and workload for the welders, significantly reducing welding efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum bronze welding device in order to solve the above problems, thereby improving the problem that the existing aluminum bronze workpiece welding process is relatively complicated and slows down the welding efficiency of the aluminum bronze workpiece.

[0005] The present invention achieves the above-mentioned object through the following technical solution: an aluminum bronze welding device, comprising a welding gun housing, a tungsten rod installed inside the welding gun housing, both ends of the tungsten rod extending to the outside of the welding gun housing, and a processing device installed on the surface of the welding gun housing; wherein the processing device comprises a ring frame fixedly connected to one end of the welding gun housing, the tungsten rod being arranged on the inner side of the ring frame, a water cooling mechanism installed inside the ring frame, an end of the water cooling mechanism away from the ring frame extending through the ring frame and extending to the outside of the welding gun housing, a windproof mechanism connected to the water cooling mechanism installed on the surface of the ring frame, and a cleaning mechanism in contact with the tungsten rod installed on the inner side of the ring frame.

[0006] Preferably, the windproof mechanism includes two first arc plates that are symmetrically hinged to the surface of the ring frame, the two first arc plates together form a circular ring, the inner sides of the first arc plates are rotatably connected to two transmission shafts that are rotatably connected to the ring frame, the surfaces of the two upper transmission shafts are fixedly connected to the first spur gears, the two first spur gears are meshed and connected, the surfaces of the two upper transmission shafts are fixedly connected to a coil spring that is fixedly connected to the ring frame, the coil spring is always in a compressed state, the surface of one of the lower transmission shafts is rotatably connected to the first fan-shaped connecting box that is connected to the ring frame, the inner wall of the first fan-shaped connecting box is rotatably provided with a first baffle, the first baffle is rotatably connected to the center of the first fan-shaped connecting box, the lower end of the first baffle passes through the first fan-shaped connecting box and is fixedly connected to the adjacent transmission shaft, One of the vertical side walls of the first fan-shaped connecting box is fixedly connected to a first water inlet pipe connected to the first fan-shaped connecting box, and the end of the first water inlet pipe is in pressure-free contact with the first baffle. The arc-shaped vertical side wall of the first fan-shaped connecting box is fixedly connected to a first water outlet pipe connected to the first fan-shaped connecting box. Through the coordinated use of the windproof mechanism and the water cooling mechanism, when the water cooling mechanism is operating normally, water can push the first baffle, causing the two first arc-shaped plates to rotate toward each other and form a circular barrier, which can not only accurately guide the shielding gas ejected from the welding gun housing to the weld, but also block the external airflow, reducing the probability of external airflow disturbing the shielding gas, making it more stable for workers to weld aluminum bronze workpieces, thereby achieving a good windproof effect, and without the need for workers to actively adjust, reducing the burden on workers.

[0007] Preferably, the maximum rotation angle of the first curved plate on the surface of the ring frame through the transmission shaft is forty degrees, and the angle between the first water inlet pipe and the first water outlet pipe is forty-five degrees, which can ensure that the two first curved plates can fit tightly together under the drive of water power, reducing the probability of gap formation.

[0008] Preferably, the surface of the first curved plate away from the ring frame is slidably connected to the second curved plate, and the two second curved plates together form a circular ring. The surface of the first curved plate away from the ring frame is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to a slider fixedly connected to the inner side of the second curved plate. This can not only extend the blocking range of the windproof mechanism, but also can make adaptive adjustments according to the staff to expand the practicality and applicability of the windproof mechanism.

[0009] Preferably, a first spring is provided on the inner side of the slide groove, and the top and bottom of the first spring are between the slide groove and the slider. The first spring is always in a compressed state, which can enable the second arc plate to reset itself after losing resistance, and can also increase the stability of the second arc plate in use.

[0010] Preferably, two mounting cavities are provided on the inner side of the ring frame, and the cleaning mechanism includes two mounting plates and a fixing sleeve, the mounting plate being slidably connected to the inner wall of the mounting cavity, the mounting plate being fixedly connected to an aerogel block at one end away from the first curved plate, the aerogel block being passed through the mounting cavity and in contact with the surface of the tungsten rod at one end of the mounting plate being away from the aerogel block, the connecting belt being fixedly connected to the end of the connecting belt being away from the mounting plate being fixedly connected to a winding wheel rotatably connected to the mounting cavity, the surface of the winding wheel being fixedly connected to a second spur gear, the surface of the second spur gear being meshed with a rack slidably connected to the mounting cavity, the end of the rack being away from the mounting plate being passed through the mounting cavity and extending to the outside of the ring frame, a second spring being provided inside the mounting cavity, the top and bottom of the second spring being between the mounting plate and the mounting cavity, the second spring being always in a compressed state, and the fixing The sleeve is fixedly connected to the end of the tungsten rod away from the ring frame, and the end of the fixed sleeve close to the welding gun housing is fixedly connected to the mounting tube, and the surface of the mounting tube is slidably connected to an adjusting tube rotatably connected to the welding gun housing. A spiral groove is provided inside the adjusting tube, and the inner wall of the spiral groove is slidably connected to a guide block fixedly connected to the adjusting tube. Through the coordinated use of the cleaning mechanism and the water cooling mechanism, in the process of water passing through the second fan-shaped connecting box, the second baffle pushes the tungsten rod outward quickly under the push of water, which not only enables the tungsten rod to pass through the ring frame by itself so that the staff can use it for normal welding, but also rubs against the aerogel block during the movement, and the aerogel block can also wipe off impurities on the surface of the tungsten rod, so that the surface of the tungsten rod can always be kept clean without the staff actively cleaning it, which not only reduces the maintenance burden of the staff, but also ensures the conductivity of the tungsten rod, thereby improving the welding quality of the aluminum bronze workpiece.

[0011] Preferably, the surface of the second spur gear is meshedly connected with a third spur gear rotatably connected to the mounting cavity, and the upper end of the third spur gear is meshedly connected with a fourth spur gear meshed with the rack. The gear ratio of the second spur gear to the third spur gear is three to one, and the gear ratio of the third spur gear to the fourth spur gear is one to three. After the first arc plate presses the rack completely into the mounting cavity, this can ensure that the aerogel block is completely received in the mounting cavity to reduce the obstruction to the flow of protective gas.

[0012] The top end face of said sliding panel also is provided with an interlocking structure, and the interlocking structure of said sliding panel also is provided with an interlocking structure.

[0013] Preferably, the angle between the beginning and end of the spiral groove is one hundred and ten degrees, and the maximum angle of rotation of the second baffle inside the second fan-shaped connecting box is ninety degrees, which can ensure that the second baffle has sufficient rotation space, not only ensuring that the water can flow normally, but also ensuring the stability of the tungsten rod during operation.

[0014] Preferably, the water-cooling mechanism includes a water-cooling inlet pipe and a water-cooling outlet pipe, the water-cooling inlet pipe and the water-cooling outlet pipe are both spiral in shape, the water-cooling inlet pipe and the water-cooling outlet pipe are both fixedly connected to the surface of the welding gun housing, the ends of the water-cooling inlet pipe and the water-cooling outlet pipe close to the tungsten rod both penetrate to the outside of the welding gun housing, the end of the water-cooling inlet pipe close to the tungsten rod is fixedly connected and communicated with the second water inlet pipe, the end of the second water outlet pipe away from the second fan-shaped connecting box is fixedly connected and communicated with the first water inlet pipe, and the end of the water-cooling outlet pipe close to the tungsten rod is fixedly connected and communicated with the first water outlet pipe. By setting up a water-cooling mechanism, in the process of water passing through the water-cooling inlet pipe or the water-cooling outlet pipe, water can take away the heat of the water-cooling inlet pipe or the water-cooling outlet pipe, so that the water-cooling inlet pipe and the water-cooling outlet pipe absorb the heat in the welding gun housing, which can reduce the operating stability of the welding gun housing, so as to reduce the probability of the welding gun housing scalding the staff.

[0015] The beneficial effects of the present invention are:

[0016] Through the coordinated use of the windproof mechanism and the water-cooling mechanism, when the water-cooling mechanism operates normally, water can push the first baffle, causing the two first curved plates to rotate toward each other and form a circular barrier. This not only accurately guides the shielding gas ejected from the welding gun housing to the weld, but also blocks external airflow, reducing the probability of external airflow disturbing the shielding gas, making it more stable for workers to weld aluminum-bronze workpieces, thereby achieving a good windproof effect. Without the need for workers to actively adjust, the burden on workers is reduced.

[0017] Through the coordinated use of the cleaning mechanism and the water cooling mechanism, when water passes through the second sector-shaped connecting box, the second baffle is pushed outward quickly by the water. This not only allows the tungsten rod to pass through the ring frame on its own, so that the workers can use it normally for welding, but also, during the movement, it rubs against the aerogel block, which can also wipe away impurities on the surface of the tungsten rod. The surface of the tungsten rod can always be kept clean without the need for active cleaning by the workers. This not only reduces the maintenance burden on the workers, but also ensures the conductivity of the tungsten rod, thereby improving the welding quality of aluminum-bronze workpieces.

[0018] By providing a water cooling mechanism, when water passes through the water cooling inlet pipe or the water cooling outlet pipe, the water can take away the heat of the water cooling inlet pipe or the water cooling outlet pipe, so that the water cooling inlet pipe and the water cooling outlet pipe absorb the heat in the welding gun housing, which can reduce the operating stability of the welding gun housing and reduce the probability of the welding gun housing scalding the workers.

The surface of one of the lower transmission shafts 602 is rotatably connected to the first fan-shaped connection box 605 that is connected to the ring frame 4. The inner wall of a fan-shaped connecting box 605 is rotatably provided with a first baffle 606, and the first baffle 606 is rotatably connected to the center of the circle of the first fan-shaped connecting box 605.

A slider 611 is connected to the inner side of the second curved plate 609. During the rotation of the first curved plate 601, the first curved plate 601 drives the second curved plate 609 to rotate together through the slide groove 610 and the slider 611, and when the two first curved plates 601 are in contact with each other, the two second curved plates 609 are also in contact with each other. A first spring 612 is provided on the inner side of the slide groove 610. The top and bottom of the first spring 612 are between the slide groove 610 and the slider 611. The first spring 612 is always in a compressed state. When the second curved plate 609 loses resistance, the first spring 612 returns the second curved plate 609 to its initial position along the slide groove 610 through the slider 611.

[0032] As shown in Figures 3, 5, 7, 8 and 9, two mounting cavities 401 are provided on the inner side of the ring frame 4, and the cleaning mechanism 7 includes two mounting plates 701 and a fixing sleeve 708.

One end of the connecting belt 703 away from the mounting plate 701 The end is fixedly connected to a winding wheel 704 that is rotatably connected to the mounting cavity 401. The surface of the winding wheel 704 is fixedly connected to a second spur gear 705. The surface of the second spur gear 705 is meshed with a rack 706 that is slidably connected to the mounting cavity 401. The end of the rack 706 away from the mounting plate 701 passes through the mounting cavity 401 and extends to the outside of the ring frame 4. A second spring 707 is provided inside the mounting cavity 401. The top and bottom of the second spring 707 are between the mounting plate 701 and the mounting cavity 401. The second spring 707 is always in a compressed state. The fixing sleeve 708 is fixedly connected to the tungsten rod 2 away from the ring frame 4 One end of the fixing sleeve 708 is fixedly connected to the end of the welding gun housing 1 with a mounting tube 709, and the surface of the mounting tube 709 is slidably connected to an adjusting tube 710 rotatably connected to the welding gun housing 1, and a spiral groove 711 is provided inside the adjusting tube 710, and the inner wall of the spiral groove 711 is slidably connected to a guide block 712 fixedly connected to the adjusting tube 710 {the surface of the fixing sleeve 708 and the surface of the tungsten rod 2 are both provided with matching and aligned threaded holes, and the threaded holes on the fixing sleeve 708 and the tungsten rod 2 are fixed together by insulating bolts}; the surface of the second spur gear 705 is meshed with the mounting cavity 4 01 rotates, the upper end of the third spur gear 713 is meshed with the fourth spur gear 714 meshed with the rack 706, the gear ratio of the second spur gear 705 to the third spur gear 713 is three to one, and the gear ratio of the third spur gear 713 to the fourth spur gear 714 is one to three {when the rack 706 drives the fourth spur gear 714 to rotate one circle, the fourth spur gear 714 drives the third spur gear 713 to rotate one circle, the third spur gear 713 drives the second spur gear 705 to rotate three circles, and the second spur gear 705 drives the winding wheel 704 to wind three circles of the connecting belt 703};The surface of the regulating tube 710 is fixedly connected to a driven bevel gear 715, and the upper surface of the driven bevel gear 715 is meshedly connected to the driving bevel gear 716, and the upper end of the driving bevel gear 716 is fixedly connected to a second baffle 717, and the surface of the second baffle 717 is rotatably connected to a second fan-shaped connecting box 718 fixedly connected to the welding gun housing 1, and the second baffle 717 is rotatably connected to the center of the second fan-shaped connecting box 718, and one of the vertical side walls of the second fan-shaped connecting box 718 is fixedly connected to a second water inlet pipe 719 communicating with the second fan-shaped connecting box 718, and the end of the second water inlet pipe 719 is in pressure-free contact with the second baffle 717, and the arc-shaped vertical side wall of the second fan-shaped connecting box 718 is fixedly connected to a second water outlet pipe 720 communicating with the second fan-shaped connecting box 718, and the surface of the mounting tube 709 is sleeved with a third spring 721, and the top and bottom of the third spring 721 are between the fixed sleeve 708 and the regulating tube 710 The third spring 721 is always in a compressed state. A guide groove is defined at the end of the adjusting tube 710 away from the fixing sleeve 708. The inner wall of the guide groove is slidably connected to a guide rod fixedly connected to the welding gun housing 1. When the second baffle 717 loses resistance, the third spring 721 quickly pushes back the fixing sleeve 708, which drives the tungsten rod 2 to retract into the inner side of the ring frame 4. Simultaneously, the fixing sleeve 708 rotates the mounting tube 709, which in turn drives the guide block 712 back. The guide block 712 drives the adjusting tube 710 to rotate via the spiral groove 711. The adjusting tube 710 then drives the driven bevel gear 715, which in turn drives the driving bevel gear 716, which in turn drives the second baffle 717 to its initial position. The included angle between the beginning and end of the spiral groove 711 is 110 degrees. The maximum rotation angle of the second baffle 717 within the second sector-shaped connecting box 718 is 90 degrees.

[0033] As shown in Figure 3, the water cooling mechanism 5 includes a water cooling inlet pipe 501 and a water cooling outlet pipe 502. The shapes of the water cooling inlet pipe 501 and the water cooling outlet pipe 502 are both spiral. The water cooling inlet pipe 501 and the water cooling outlet pipe 502 are both fixedly connected to the surface of the welding gun housing 1. The ends of the water cooling inlet pipe 501 and the water cooling outlet pipe 502 close to the tungsten rod 2 are both penetrated to the outside of the welding gun housing 1. The end of the water cooling inlet pipe 501 close to the tungsten rod 2 is fixedly connected to and communicated with the second water inlet pipe 719, and the second water outlet pipe 720 is away from the second fan-shaped connection. One end of the connecting box 718 is fixedly connected to and communicated with the first water inlet pipe 607, and one end of the water-cooling outlet pipe 502 near the tungsten rod 2 is fixedly connected to and communicated with the first water outlet pipe 608 {in the process of water passing through the water-cooling inlet pipe 501 or the water-cooling outlet pipe 502, the water can take away the heat of the water-cooling inlet pipe 501 or the water-cooling outlet pipe 502, so that the water-cooling inlet pipe 501 and the water-cooling outlet pipe 502 absorb the heat in the welding gun housing 1, which can reduce the operating stability of the welding gun housing 1, thereby reducing the probability of the welding gun housing 1 scalding the staff}.

[0034] When the present invention is in use, when the staff needs to use an argon arc welding gun, the staff first connects the water-cooling inlet pipe 501 and the water-cooling outlet pipe 502 to the external cooling circulating water machine, and then turns on the cooling circulating water machine. The cooling circulating water machine transports water into the water-cooling inlet pipe 501, and the water-cooling inlet pipe 501 guides the water into the second water inlet pipe 719. The second water inlet pipe 719 guides the water into the second fan-shaped connecting box 718. Since the second baffle 717 hinders the normal passage of water, the water pushes the second baffle 717 to rotate in the process of passing through the second fan-shaped connecting box 718. The second baffle 717 rotates through the second water outlet pipe 720, so that the second water inlet pipe 719 and the second water outlet pipe 720 are on the same side of the second baffle 717. During the rotation of the second baffle 717, the second baffle 717 drives the active bevel gear 716 to rotate, the active bevel gear 716 drives the driven bevel gear 715 to rotate, the driven bevel gear 715 drives the adjusting tube 710 to rotate, the adjusting tube 710 drives the spiral groove 711 to rotate, the spiral groove 711 drives the guide block 712 to approach the welding gun housing 1, the guide block 712 drives the fixing sleeve 708 to approach the welding gun housing 1, and the fixing sleeve 708 drives the tungsten rod 2 to pass through the aerogel block 702. At this time, the aerogel block 702 can scrape off impurities adhering to the surface of the tungsten rod 2, so that the end of the tungsten rod 2 is always kept clean.

[0035] After the water enters the interior of the second water outlet pipe 720 through the second fan-shaped connecting box 718, the water flows into the first water inlet pipe 607 along the second water outlet pipe 720. The first water inlet pipe 607 guides the water into the first fan-shaped connecting box 605. At this time, the first baffle 606 prevents the water from entering the first fan-shaped connecting box 605 normally. The subsequent water pushes the first baffle 606 to rotate in the process of entering the first fan-shaped connecting box 605 until the first baffle 606 rotates through the first water outlet pipe 608, and makes the first water inlet pipe 607 and the first water outlet pipe 608 on the same side of the first baffle 606 at the same time. During the rotation of the first baffle 606, the first baffle 606 drives the transmission shaft 602 connected thereto to rotate, and the transmission shaft 602 drives the first curved plate 601 connected thereto to approach the ring frame 4. The first curved plate 601 drives the adjacent first spur gear 603 to rotate via the transmission shaft 602 connected thereto. The first spur gear 603 drives the other first spur gear 603 to rotate in the opposite direction. The other first spur gear 603 drives the other first curved plate 601 to approach the ring frame 4 via the transmission shaft 602 connected thereto. When the two first curved plates 601 are both attached to the surface of the ring frame 4, the two first curved plates 601 fit together and form a circular ring. During the subsequent welding process, the circular ring formed by the two first curved plates 601 can not only accurately guide the shielding gas ejected from the welding gun housing 1 to the weld, but also forms a closed-loop barrier, reducing the probability of external airflow disturbing the shielding gas, making welding of aluminum-bronze workpieces more stable for the workers.

[0036] When the first curved plate 601 approaches the ring frame 4, the inner side of the first curved plate 601 contacts the rack 706 after rotating for a certain angle. During the subsequent rotation, the first curved plate 601 presses the rack 706 into the installation cavity 401. The rack 706 drives the fourth spur gear 714 to rotate, and the fourth spur gear 714 drives the third spur gear 713 to rotate. The third spur gear 713 drives the second spur gear 705 to rotate in the opposite direction. The second spur gear 705 drives the winding wheel 704 to rotate. The winding wheel 704 retracts the connecting belt 703. The connecting belt 703 pulls the installation plate 701 away. The installation plate 701 drives the aerogel block 702 to separate from the tungsten rod 2 and retract it into the installation cavity 401.

[0037] After the water flows out of the first fan-shaped connection box 605 through the first water outlet pipe 608, the water flows into the water-cooled outlet pipe 502 along the first water outlet pipe 608. The water-cooled outlet pipe 502 guides the water into the cooling circulating water machine, so that the cooling circulating water machine cools the water and then circulates it into the water-cooled inlet pipe 501.

[0038] 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.
