And the cleaning means for the equipment usually adopts manual cleaning, which affects the efficiency of equipment welding and the welding firmness.

[0006] Therefore, we propose a welding device for auxiliary guiding equipment transformation to solve the problems raised above. Summary of the Invention

[0012] Preferably, the positioning mechanism includes a secondary bidirectional threaded rod, and the secondary bidirectional threaded rod is rotatably arranged on the left and right sides above the positioning platform through bearings, and the front and rear outer walls of the symmetrically arranged secondary bidirectional threaded rod are both provided with fixed threads passing through a positioning slide, and the top surface of the symmetrically arranged positioning slide is fixedly connected to the interference limit block.

[0013] Preferably, the positioning mechanism includes filter screen slots, and the filter screen slots are equidistantly arranged in the middle of the positioning platform, and the filter screen slots are through-connected to the dust collecting chamber inside the welding platform, and dust removal scrapers are connected to the front and rear sides of the top surface of the positioning platform through resistance springs.

[0014] Preferably, the positioning mechanism includes a traction steel cable, and the lower end of the traction steel cable is fixedly connected to the left and right ends of the outer side of the dust removal scraper, and the middle part of the traction steel cable is wrapped around the outer side of the positioning platform, and the upper end of the traction steel cable is fixedly connected to the left and right sides of the bottom surface of the positioning slide, and at the same time, the sliding directions of the positioning slide and the dust removal scraper are set opposite to each other.

[0015] Preferably, the cleaning mechanism includes a guide slide rod, and the guide slide rod is fixedly installed on the front and rear sides of the bottom of the positioning platform, and the guide slide rod slides through and is connected to the outer end of the traction slide plate, and the guide slide rod and the traction slide plate are connected to each other through a traction spring, and a traction protrusion is fixedly provided on the bottom surface of the traction slide plate.

[0016] Preferably, the brush cleaning mechanism includes a main transmission shaft and an auxiliary transmission shaft, and both the main transmission shaft and the auxiliary transmission shaft are rotatably arranged on the inner outside of the brush cleaning flip plate through bearings, and the upper end of the main transmission shaft is meshingly connected to the shaft of the rotating brush plate through a first bevel gear group, and the lower end of the main transmission shaft is meshingly connected to the auxiliary transmission shaft through a second bevel gear group.

[0017] Preferably, the brush cleaning mechanism includes a transmission rack, and the transmission rack is fixedly installed on the left and right sides of the dust collecting chamber, and a transmission gear is meshed below the transmission rack, and the transmission gear is fixedly connected to the end of the auxiliary transmission shaft away from the main transmission shaft, and the transmission gear is meshed with the transmission rack through the brush cleaning flip plate when it is in a vertical state, and the transmission gear is disengaged from the transmission rack through the brush cleaning flip plate when it is in a horizontal state.

[0018] Preferably, the brush cleaning mechanism includes a resistance horizontal plate, and the resistance horizontal plate is fixedly installed on the left and right sides of the dust collecting chamber, and the resistance horizontal plates on the left and right sides resist each other with the traction slide plate when the positioning platform slides inward, and the resistance horizontal plate resists the traction slide plate so that the hinged brush cleaning flip plate is limited by the positioning platform and rotates.

[0019] Compared with the prior art, the invention has the following beneficial effects: the auxiliary guided equipment modification welding device positions the equipment through the abutment limit block above the positioning platform, and cleans and collects the powder chips through the dust removal scraper during positioning and release, and at the same time, the cleaning brush flip plate that follows the movement cleans the welding end face of the equipment and then stores it at the bottom of the positioning platform, and the welding of the equipment on both sides by the welding unit will not cause obstacles, thereby improving the welding efficiency and the firmness of the equipment. The specific contents are as follows:

[0020] 1. The secondary bidirectional threaded rod inside the positioning platform is connected through a pulley assembly so that after the motor drives the secondary bidirectional threaded rod to rotate, the positioning slides connected by threads on the front and rear sides drive the top interference limit block to move inward synchronously, and then the equipment is positioned through the interference limit block to prevent displacement and dislocation during the welding process.

[0021] 2. During the movement of the positioning slide table, the traction cable is tightened, causing the dust removal scraper fixedly connected to the bottom end of the traction cable to be driven to move outside the positioning platform, so that the powder debris to be cleaned by the cleaning mechanism later can fall into the filter sieve slots opened on the top surface of the positioning platform, and then be collected through the dust collection cavity.

[0022] When the equipment is released, the positioning slide table that moves in the reverse reset direction relaxes the traction cable, so that the dust removal scraper not stretched by the traction cable slides inward under the compression of the abutting spring, and then drives the powder debris falling on the top surface of the positioning platform to slide inward, and then fall through the filter sieve slots, avoiding powder debris from contaminating the equipment for subsequent welding processing.

[0023] 3. The main bidirectional threaded rod drives the positioning platform to slide inward. When the transmission gear moves, it meshes with the transmission rack, causing the secondary transmission rotating shaft and the primary transmission rotating shaft to rotate. At the same time, the first bevel gear set drives the rotating brush disc engaged and connected to rotate inside the cleaning and flipping plate, so that the cleaning and flipping plate can clean and remove dust from the end face to be welded of the equipment that fits against the inner end.

[0024] 4. The traction slide plate contacts the abutting cross plate through the traction bump. After the positioning platform abuts against the cleaning and flipping plate, it rotates from the vertical state to the horizontal state, and the rotated cleaning and flipping plate is stored through the movement of the positioning platform, ensuring that there will be no obstructive influence when welding the equipment on both sides by the welding unit, and improving the efficiency and welding firmness during equipment welding.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1-12 , the present invention provides the following technical solutions:

[0040] Embodiment 1: In order to solve the problems existing in the actual use of welding devices for existing equipment, this embodiment adopts the following technical scheme: a welding device for auxiliary guided equipment modification, including a welding platform 1, and a dust collecting chamber 2 opened inside the welding platform 1, and a welding unit 25 is slidably arranged above the middle part of the welding platform 1; positioning mechanisms are arranged on both sides of the upper left and right sides of the welding platform 1, and the positioning mechanism includes a positioning platform 3, and both sides of the top face of the positioning platform 3 are provided with interference limit blocks 4 for positioning the equipment; the positioning mechanism includes a main bidirectional threaded rod 8, and the main bidirectional threaded rod 8 is rotatably arranged on the front and rear sides of the top face of the welding platform 1 through bearings, and the main bidirectional threaded rod 8 is threadedly connected to the outer ends of the left and right positioning platforms 3, and the rotation of the main bidirectional threaded rod 8 drives the left and right positioning platforms 3 to move in the opposite direction.

[0041] The positioning mechanism includes a pair of bidirectional threaded rods 9, and the pair of bidirectional threaded rods 9 are rotatably arranged on the left and right sides above the positioning platform 3 through bearings, and the front and rear outer walls of the symmetrically arranged pair of bidirectional threaded rods 9 are fixedly threaded with positioning slides 10, and the top surfaces of the symmetrically arranged positioning slides 10 are fixedly connected to the abutment limit blocks 4; the positioning mechanism includes filter screen slots 11, and the filter screen slots 11 are equidistantly arranged in the middle of the positioning platform 3, and the filter screen slots 11 are aligned with the inner surface of the welding platform 1. The dust collecting chambers 2 are connected through each other, and the front and rear sides of the top surface of the positioning platform 3 are connected to the dust removal scraper 13 through the resistance spring 12; the positioning mechanism includes a traction steel cable 14, and the lower end of the traction steel cable 14 is fixedly connected to the left and right ends of the outer side of the dust removal scraper 13, and the middle part of the traction steel cable 14 is wound around the outer side of the positioning platform 3, and the upper end of the traction steel cable 14 is fixedly connected to the left and right sides of the bottom surface of the positioning slide 10, and the sliding directions of the positioning slide 10 and the dust removal scraper 13 are set opposite to each other.

[0042] like Figure 5 , Figures 7-8 As shown, the equipment is placed in the middle of the top surface of the positioning platform 3 on the left and right sides of the top surface of the welding platform 1, and then the secondary bidirectional threaded rods 9 on the left and right sides inside the positioning platform 3 are connected through a pulley assembly, so that after the motor drives the secondary bidirectional threaded rod 9 to rotate, the positioning slide 10 threadedly connected on the front and rear sides drives the top interference limit block 4 to move inward synchronously, and then the equipment is positioned by the interference limit block 4 to prevent displacement and misalignment during welding.

[0043] Furthermore, the positioning slide 10 moving above the positioning platform 3 drives the traction cable 14 to tighten during the movement, so that the dust removal scraper 13 fixedly connected to the bottom end of the traction cable 14 is driven to move to the outside of the positioning platform 3, so that the powder and debris subsequently cleaned by the cleaning mechanism can fall into the filter screen slot 11 opened on the top surface of the positioning platform 3, and then be collected by the dust collecting chamber 2.

[0044] At the same time, when the equipment is released, the positioning slide 10 that moves in the reverse reset direction relaxes the traction cable 14, so that the dust removal scraper 13 that is not stretched by the traction cable 14 slides inward under the compression of the resistance spring 12, thereby driving the powder chips that fall on the top surface of the positioning platform 3 to slide inward, and then fall through the filter screen slot 11, so as to prevent the powder chips from contaminating the equipment for subsequent welding processing.

[0045] Embodiment 2: In order to solve the problems existing in the actual use of welding devices for existing equipment, this embodiment adopts the following technical scheme: brush cleaning mechanisms are provided on both sides of the upper left and right sides of the welding platform 1, and the brush cleaning mechanisms include a traction slide 5, and the inner ends of the traction slides 5 on both sides are rotatably installed with brush cleaning flip plates 6 through torsion springs, and the upper outer sides of the brush cleaning flip plates 6 are rotatably provided with a rotating brush disc 7 for cleaning the welding surface of the equipment through a bearing; the brush cleaning mechanism includes a guide slide bar 15, and the guide slide bar 15 is fixedly installed on the front and rear sides of the bottom of the positioning platform 3, and the guide slide bar 15 is slidably connected to the outer end of the traction slide bar 5, and the guide slide bar 15 and the traction slide bar 5 are mutually connected through a traction spring 16, and at the same time, a traction protrusion 17 is fixedly provided on the bottom surface of the traction slide bar 5.

[0046] The brush cleaning mechanism includes a main transmission shaft 18 and a secondary transmission shaft 19, and both the main transmission shaft 18 and the secondary transmission shaft 19 are rotatably arranged on the inner and outer sides of the brush cleaning flip plate 6 through bearings, and the upper end of the main transmission shaft 18 is meshed and connected to the rotating shaft of the rotating brush disc 7 through a first bevel gear set 20, and the lower end of the main transmission shaft 18 is meshed and connected to the secondary transmission shaft 19 through a second bevel gear set 21; the brush cleaning mechanism includes a transmission rack 22, and the transmission rack 22 is fixedly installed on the left and right sides of the dust collecting chamber 2, and a transmission gear 23 is meshed below the transmission rack 22, and the transmission gear 23 is fixedly connected to one end of the secondary transmission shaft 19 away from the main transmission shaft 18, and the transmission gear 23 is meshed with the transmission rack 22 when the brush cleaning flip plate 6 is in a vertical state, and the transmission gear 23 is disengaged from the transmission rack 22 when the brush cleaning flip plate 6 is in a horizontal state.

[0047] The brush cleaning mechanism includes a resistance transverse plate 24, and the resistance transverse plate 24 is fixedly installed on the left and right sides of the dust collecting chamber 2, and the resistance transverse plates 24 on the left and right sides resist each other with the traction slide plate 5 when the positioning platform 3 slides inward, and the resistance transverse plate 24 resists the traction slide plate 5 so that the hinged brush cleaning flip plate 6 is limited by the positioning platform 3 and rotates.

[0048] like Figures 3-4 , Figures 10-11 As shown, the main bidirectional threaded rod 8 connected to the top of the welding platform 1 through the pulley assembly is driven by the motor to rotate, and then the main bidirectional threaded rod 8 drives the positioning platforms 3 connected by threads on the left and right sides to slide inward synchronously, and the transmission gear 23 under the positioning platform 3 engages with the transmission rack 22 when moving, and then drives the auxiliary transmission shaft 19 after rotation, and the main transmission shaft 18 is driven by the second bevel gear group 21. At the same time, the first bevel gear group 20 drives the meshing rotating brush disc 7 to rotate inside the cleaning flip plate 6, so that the cleaning flip plate 6 can clean and dust the end face of the equipment to be welded that is attached to the inner end, so as to avoid the situation of cold welding and desoldering due to dust.

[0049] like Figure 6 , Figure 9 , Figure 12 As shown, the positioning platform 3 drives the traction slide plate 5 on the bottom surface to move synchronously. When the traction slide plate 5 contacts each other through the traction protrusion 17 at the bottom and the abutting cross plate 24, the traction slide plate 5 is limited and then squeezes the traction spring 16 along the guide slide bar 15 and no longer moves with the positioning platform 3. At the same time, after the positioning platform 3 abuts against the brush cleaning flip plate 6 through the inner end, the brush cleaning flip plate 6 is rotated from a vertical state to a horizontal state, and the rotated brush cleaning flip plate 6 is stored through the movement of the positioning platform 3, ensuring that there will be no obstruction when welding the equipment on both sides through the welding unit 25, thereby improving the efficiency of equipment welding and the firmness of welding.
