Description

Technical Field

[0001] The invention relates to the technical field of welding platforms, and in particular to a multi-station turret-type three-dimensional hardware welding platform. Background Art

[0002] Hardware metal structural parts generally refer to metal parts made of gold, silver, copper, iron, tin, and other metals formed through processes such as casting, forging, and stamping. Side tubes are welded to the outer wall of the main circular tube on both sides as supports or connection points for securing other components. This is a structural design method that efficiently utilizes space and materials. For example, valve pipes and hot air ducts are used. Welding the side tubes to the outer wall of the main circular tube usually requires a welding platform.

[0003] In this regard, the present application designs a multi-station turret-type three-dimensional welding platform for hardware. Traditional welding platforms usually use a single tooling fixture, which can only clamp and weld separate main circular tubes and side circular tubes. It requires manual repeated disassembly of the workpiece or manual adjustment of the tooling. The operation is cumbersome, time-consuming and labor-intensive, which further affects the efficiency of welding work. When it is necessary to weld side circular tubes on both sides of the outer wall of the main circular tube, since the weight of the main circular tube is much greater than that of the side circular tube, it is difficult to clamp the two side circular tubes at the same time and make them drive the main circular tube to rotate synchronously under the premise of ensuring the welding accuracy of the connection between the main circular tube and the side circular tube. Clamping and welding the two side circular tubes in turn will further affect the welding efficiency. Summary of the Invention

[0045] The clamping group 64 also includes a mating tube 641, which is rotatably penetrated by an end thereof away from the pentagonal mounting platform 3, and a boss threaded rod 644 is installed on the telescopic end of the telescopic shaft 643.

[0046] On the turntable 2, mounting grooves are provided on the inner walls on both sides of the shorter section of each T-shaped hole. Wedge-shaped baffles 21 are slidably connected in the left and right mounting grooves through compression springs. The two wedge-shaped baffles 21 are symmetrically arranged. A material return groove is provided at the position corresponding to one of the T-shaped holes on the protective cover plate 4, and a material guide slide 41 is installed at the position corresponding to the material return groove. Feeding docking holes are respectively provided on the side walls of the support box 1 corresponding to the positions of the two servo motors 645.

[0047] When implementing:

[0048] The turntable 2 in the present application adopts a multi-station continuous processing method. First, the main round tube is sent between the two front-side abutting cones 523 by manual or external loading devices. Under the action of the compression spring, the two front-side abutting cones 523 will jointly support and clamp the main round tube. At this time, under the friction-reducing action of multiple balls, the main round tube can rotate freely. During this period, the main round tube will squeeze the corresponding clamping rod 61 and the boss abutting rod 62, so that they will retract into the corresponding circular slide groove 1 and circular slide groove 2 respectively. After that, under the action of the compression spring, Under, the corresponding clamping rod 61 and the boss tightening rod 62 will press against the main round tube to assist in clamping it, and then the intermittent motor 51 is used to control the intermittent rotation of the turntable 2. The turntable 2 drives the main round tube to rotate clockwise to a proper angle through the two tightening cones 523, so that it is located directly above the adjacent avoidance hole on the left. It should be noted that after each intermittent rotation of the turntable 2, multiple T-shaped holes will be aligned with the corresponding avoidance holes, and two of the avoidance holes corresponding to the positions of the feeding docking holes are also T-shaped holes to serve as loading ports.

[0049] When the side round tubes are loaded and welded for the first time, the side round tube conveying and lifting device outside the left feeding docking hole will first convey multiple side round tubes to the bottom of the corresponding avoidance hole in turn, and then convey the side round tubes upward to a position at the same horizontal height as the main round tube. Then, the upper and lower electromagnets 642 here are controlled to start working, and the connected telescopic shaft 643 is controlled to rotate by the servo motor 645. At this time, the upper and lower electromagnets 642 will jointly magnetically attract the matching cylinder 641 to prevent it from rotating. When the telescopic shaft 643 drives the boss threaded rod 644 to rotate, the boss threaded rod 644 will thread the threaded section on the matching cylinder 641 Under the action of , it is gradually rotated out toward the pentagonal mounting platform 3. During this period, the clamping end of the boss threaded rod 644 is inserted into the side tube and drives it to continue to approach the pentagonal mounting platform 3 until the welding end of the side tube is tightly fitted on the outer wall of the main tube. The upper and lower electromagnets 642 can be controlled to stop working. At this time, the matching cylinder 641 can rotate freely. It should be noted that if there is a small angle deviation before the side tube is tightly fitted to the outer wall of the main tube, it will make adaptive rotation compensation under the thrust of the boss threaded rod 644 after contacting the outer wall of the main tube, thereby achieving the effect of the welding end of the side tube being tightly fitted on the outer wall of the main tube.

[0050] Then, the servo motor 645 controls the telescopic shaft 643 to drive the boss threaded rod 644 to rotate. At this time, the boss threaded rod 644 is rotated to the maximum distance, and the matching cylinder 641 can rotate freely. The boss threaded rod 644 will drive the matching cylinder 641 to rotate together, and the V-shaped clamping plate connected to the magnetic attraction on the corresponding clamping rod 61 will clamp the main tube tightly, which will jointly drive the main tube and the side tube to rotate in a circle around the boss threaded rod 644. At the same time, the welding of the side tube and the main tube is performed by an external laser welding head (not shown in the drawings). Automatic welding is performed at the wiring position. When welding is completed, the upper and lower electromagnets 642 are controlled to start working. At the same time, the servo motor 645 controls the telescopic shaft 643 again to drive the boss threaded rod 644 to rotate in the opposite direction until the boss threaded rod 644 retracts into the matching tube 641. The servo motor 645 stops working. The freely retractable boss threaded rod 644 and the adaptively tightened clamping rod 61 are used in combination. The clamping is firm and convenient, thereby achieving the effect of driving the main round tube and the side round tube to rotate in a circle around the boss threaded rod 644 to facilitate welding.

[0051] When flipping, the intermittent rotation of the turntable 2 is controlled by the intermittent motor 51. It should be noted that whenever the turntable 2 rotates intermittently, multiple counterweight slides 633 will slide along the guide slot 632. The positions of the two semi-annular slots on the guide slot 632 correspond to the positions of the contact plate 635 and the material guide slide 41 respectively. At this time, the counterweight slide 633 corresponding to the contact plate 635 will slide along the guide slot 632. When the counterweight slide 633 slides into the corresponding semi-annular slot, this counterweight slide 633 will drive the annular sleeve to slide along the corresponding waist-shaped slot toward the side away from the pentagonal mounting platform 3, and under the action of the gravity of the counterweight slide 633's own counterweight, it will slide along the matching inclined slot on the corresponding clamping rod 61 for compensation, thereby achieving the effect of squeezing the clamping rod 61 back into the corresponding circular slot.

[0052] During the period when the turntable 2 drives the main round tube to rotate clockwise to a proper angle through the two abutting cones 523, the side round tube welded on the main round tube will slide along the upper surface of the spiral slide plate 634, and under the guiding and limiting action of the abutting plate 635, this side round tube will drive the main round tube to perform adaptive rotation compensation around the corresponding supporting vertical plate 522, and under the action of gravity, the side round tube will gradually turn 180 degrees toward one side of the pentagonal mounting platform 3 and fit into the upper end of the wedge-shaped supporting plate 636. This side round tube is still in the same position as the main round tube. Horizontal height: It should be noted that when the side round tube is welded and the boss threaded rod 644 is retracted into the matching cylinder 641, the main round tube and the side round tube will rotate downward toward the side of the side round tube due to the imbalance of gravity. When the turntable 2 rotates intermittently, the lowest end of the spiral slide 634 can ensure smooth contact with the side round tube and synchronously rotate upward following the spiral rise of the spiral slide 634. At the same time, the lowest end of the spiral slide 634 will be slightly higher than the upper end face of the adjusting wheel 527, so that it can pass smoothly when following the intermittent rotation of the turntable 2.

[0053] Then, the side tube conveying and lifting device external to the right feeding docking hole will convey multiple side tubes to the bottom of the corresponding avoidance holes in turn, and convey the side tubes upward to a position at the same horizontal height as the main tube, repeating the first side tube clamping and welding operation. Through the cooperation of the upper and lower electromagnets 642 and the servo motor 645, the boss threaded rod 644 and the V-shaped clamping plate magnetically connected on the adaptively tightened clamping rod 61 will also jointly drive the main tube and the side tube to rotate around the boss threaded rod 644, and the external laser welding head (not shown in the drawings) will automatically weld the side tube and the main tube at the welding line position. When welding is completed, the boss threaded rod 644 is controlled to retract into the matching cylinder 641 through the cooperation of the upper and lower electromagnets 642 and the servo motor 645, and the servo motor 645 stops working, thereby achieving the effect of welding the two side tubes in turn, avoiding the tedious problem of manual repeated clamping of the main tube and the side tube, and effectively improving the welding work efficiency.

[0054] When the welded main round pipe is discharged, the intermittent motor 51 is used to control the turntable 2 to rotate intermittently again, and the welded main round pipe moves to the position corresponding to the guide slide 41. At this time, the counterweight slide 633 corresponding to the guide slide 41 slides along the guide groove 632. When the counterweight slide 633 slides into the corresponding semi-annular groove, the counterweight slide 633 will drive the annular sleeve to slide along the corresponding waist-shaped slide hole toward the side close to the pentagonal mounting platform 3, and under the action of the gravity of the counterweight slide 633's own counterweight, it will slide along the matching bevel on the corresponding clamping rod 61 to compensate, thereby achieving the effect of squeezing the clamping rod 61 out of the corresponding circular groove. At this time, the corresponding clamping rod 61 will push the welded main round pipe to the corresponding position corresponding to the guide slide 41. The main circular tube is completed, so that it is disengaged from the limit clamping of the corresponding two pressing cones 523, and under the action of the compression spring, the boss pressing rod 62 will push the corresponding side circular tube on this main circular tube for a second time to ensure that it is pushed onto the material guide slide 41 and slides out from the material guide slide 41. Similarly, when the turntable 2 is intermittently rotated by the intermittent motor 51 next time, the counterweight slide 633 at the corresponding material guide slide 41 will continue to slide along the guide slide 632 and exit the corresponding semi-annular slide. This counterweight slide 633 will drive the annular sleeve to slide along the corresponding waist-shaped slide hole to the side away from the pentagonal mounting platform 3 to return to its original position, and the counterweight slide 633 will slide along the matching inclined groove on the corresponding clamping rod 61 to compensate and return to its original position.

[0055] When it is necessary to adjust the welding position of the main round tube and the side round tube, multiple adjustment wheels 527 are rotated manually in sequence. Under the transmission action of bevel gear 2 526 and bevel gear 1 525, the corresponding screw 521 will be driven to rotate, thereby achieving the effect of adjusting the position of the corresponding two supporting vertical plates 522 through the screw 521. The welding position between the main round tube and the two side round tubes can be freely adjusted within the working range of the T-shaped hole according to actual needs. The adaptation of the multi-degree-of-freedom laser welding head will not affect all the above-mentioned work processes.

[0056] In summary, this application has the following advantages:

[0057] Advantage 1: This application adopts a multi-station continuous processing method. First, the main round tube is supported and clamped by the two front-side abutting cones 523. Then, the intermittent rotation of the turntable 2 is controlled by the intermittent motor 51. The turntable 2 drives the main round tube to rotate clockwise to a suitable angle through the two abutting cones 523, so that it is located directly above the adjacent avoidance hole on the left. Then, the side round tube conveying and lifting device outside the left feeding docking hole is used to load the side round tube. Finally, the upper and lower electromagnets 642 and the servo motor 645 cooperate with each other, and the freely retractable boss threaded rod 644 and the adaptive abutting clamping rod 61 cooperate to achieve a stable and convenient clamping, thereby achieving the effect of driving the main round tube and the side round tube to rotate in a circle around the boss threaded rod 644 for easy welding.

[0058] Advantage 2: During flipping, after the turntable 2 rotates intermittently, the counterweight slide 633 corresponding to the contact plate 635 will slide along the guide groove 632. After the counterweight slide 633 slides into the corresponding semi-annular groove, the counterweight slide 633 will drive the annular sleeve to slide along the corresponding waist-shaped slide hole toward the side away from the pentagonal mounting platform 3, and under the action of the gravity of the counterweight slide 633's own counterweight, it will slide along the matching inclined groove on the corresponding clamping rod 61 for compensation, thereby achieving the effect of squeezing the clamping rod 61 back into the corresponding circular groove 1.

[0059] Advantage three, at the same time, the side tubes welded on the main tube will slide along the upper surface of the spiral slide 634 and drive the main tube to perform adaptive rotation compensation around the corresponding support vertical plate 522, until it gradually flips 180 degrees and fits the upper end of the wedge-shaped support plate 636 to complete the flipping work, and after the turntable 2 rotates intermittently again, the counterweight slide 633 at the corresponding contact plate 635 will continue to slide along the guide slide groove 632 and exit the corresponding semi-annular slide groove, and this counterweight slide 633 will drive the annular sleeve to slide along the corresponding waist-shaped slide hole toward the side close to the pentagonal mounting platform 3 to return to its original position, and the counterweight slide 633 will slide along the matching inclined groove on the corresponding clamping rod 61 to compensate and return to its original position, thereby achieving the effect of the clamping rod 61 and the boss clamping rod 62 respectively clamping the main tube and the welded side tube.

[0060] Advantage four, when the secondary side round tube is loaded and welded, the side round tube conveying and lifting device external to the right feeding docking hole is used to load the secondary side round tube. Similarly, through the cooperation of the upper and lower electromagnets 642 and the servo motor 645, the boss threaded rod 644 and the V-shaped clamping plate magnetically connected on the adaptive clamping rod 61 here will also jointly drive the main round tube and the side round tube to rotate around the boss threaded rod 644, and the external laser welding head (not shown in the figure) here will automatically weld the welding line position of the side round tube and the main round tube, thereby achieving the effect of welding the two side round tubes in sequence, avoiding the tedious problem of manual repeated clamping of the main round tube and the side round tube.

[0061] Advantage five, when the welded main round tube is discharged, the turntable 2 is controlled to rotate intermittently again, and the welded main round tube moves to the position corresponding to the guide slide 41, and the corresponding counterweight slide 633 at the guide slide 41 will slide along the guide groove 632. When the counterweight slide 633 slides into the corresponding semi-annular groove, the counterweight slide 633 will drive the annular sleeve to slide along the corresponding waist-shaped slide hole toward the side close to the pentagonal mounting platform 3, and under the action of the gravity of the counterweight slide 633 itself, it will slide along the corresponding clamping rod 61 The cooperating inclined groove makes sliding compensation, thereby achieving the effect of squeezing the clamping rod 61 out of the corresponding circular slide groove. At this time, the corresponding clamping rod 61 will push the welded main round tube to make it break away from the limit clamping of the corresponding two tight cones 523, and the boss tight rod 62 will push the corresponding side round tube for the second time to ensure that it is pushed onto the guide slide 41 and slides out from the guide slide 41. Through multiple intermittent rotations, the main round tube and the side round tube can be welded, turned over and unloaded in sequence. The welding process is compact, which effectively improves the welding work efficiency.

[0062] Advantage six: when the welding position of the main round tube and the side round tube needs to be adjusted, multiple adjusting wheels 527 are rotated manually in sequence. Under the transmission action of bevel gear 2 526 and bevel gear 1 525, the corresponding screw 521 will be driven to rotate, thereby achieving the effect of adjusting the position of the corresponding two supporting vertical plates 522 through the screw 521. The welding position between the main round tube and the two side round tubes can be freely adjusted within the working range of the T-shaped hole according to actual needs, effectively increasing the applicability of the equipment.
