Description

Technical Field

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

[0002] Hardware metal structural parts generally refer to metal parts such as gold, silver, copper, iron, and tin formed by processes such as casting, forging, and stamping. Welding side circular tubes on the outer wall of the main circular tube as brackets or connection points for fixing other components is an efficient way to utilize space and materials. For example, in valve pipes, hot air pipes, etc., the welding work of welding side circular tubes on the outer wall of the main circular tube usually needs to be realized in cooperation with a welding platform.

[0003] In this regard, the present application designs a multi-station turret type three-dimensional welding platform for hardware parts. Traditional welding platforms usually adopt a single tooling fixture, which can only clamp a single main circular tube and side circular tube and weld them. It requires manual repeated disassembly of workpieces or manual adjustment of the tooling, with cumbersome operations, time-consuming and laborious, further affecting the welding work efficiency; when it is necessary to weld side circular tubes on both the left and right 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 two side circular tubes simultaneously and make them drive the main circular tube to rotate synchronously in a circular motion while ensuring the welding accuracy at the connection between the main circular tube and the side circular tube. And performing the clamping and welding work on the two side circular tubes sequentially will further affect the welding efficiency. Summary of the Invention

[0039] Among them, the clamping welding part 6 includes a circular slide groove 1 opened on the outer walls of the five sides of the pentagonal mounting platform 3, and a clamping rod 61 is slidably connected to the circular slide groove 1 through a compression spring. The end of the clamping rod 61 located on the outer side of the circular slide groove 1 is rotatably connected to a magnetic clamping plate, and a circular slide groove 2 is jointly opened, and a boss clamping rod 62 is slidably connected to the circular slide groove 2 through a compression spring. A telescopic matching group 63 is jointly arranged on multiple clamping rods 61, the pentagonal mounting platform 3 and the protective cover plate 4.

[0040] The telescopic matching group 63 includes a disc 631 installed on the upper end of the protective cover plate 4 through multiple connecting rods, and a guide groove 632 is provided at the lower end of the disc 631. The guide groove 632 is composed of an annular groove and two connected semi-annular grooves. The upper ends of the outer walls of multiple clamping rods 61 are symmetrically provided with matching bevel grooves along the axial direction, and the upper end of the pentagonal mounting platform 3 is provided with multiple waist-shaped sliding holes evenly distributed in a circle at the positions corresponding to the multiple matching bevel grooves. The multiple waist-shaped sliding holes are respectively connected to the corresponding circular grooves, and an annular sliding sleeve is slidably installed in the waist-shaped sliding hole.

The upper end of the counterweight sliding rod 633 is slidably connected to the guide sliding groove 632, and the lower end slides and fits the outer wall of the clamping rod 61.

[0041] The telescopic fitting group 63 also includes a spiral slide 634 installed on the inner wall of the protective cover plate 4, and a resistance plate 635 is installed on the upper side of the higher end of the spiral slide 634.

[0042] The adaptive clamping group 52 includes a lead screw 521 which is installed to rotate together on the inner walls of the left and right ends of the T-shaped hole. Two supporting vertical plates 522 are spirally connected to the lead screw 521. The opposite ends of the two supporting vertical plates 522 are connected to a clamping cone 523 through a compression spring. The opposite ends of the two clamping cones 523 are installed with a supporting slide rod 524 that slides through the corresponding supporting vertical plates 522, and a plurality of balls evenly distributed in a circle are installed on the clamping inclined surface end of the clamping cone 523.

[0043] Receiving grooves are provided at positions corresponding to one ends of multiple lead screws 521 on the turntable 2, and a bevel gear 525 fixedly connected to the lead screw 521 is provided in the receiving groove.

[0044] The clamping and welding part 6 further includes two clamping groups 64 jointly arranged on the support box 1 and the protective cover plate 4. The clamping group 64 includes a fitting cylinder 641 through which the clamping rod 61 rotatably penetrates and is installed on the protective cover plate 4. One end of the inner wall of the fitting cylinder 641 facing the pentagonal mounting table 3 is a threaded section structure, and electromagnets 642 are embedded at positions corresponding to the upper and lower sides of the outer wall of the fitting cylinder 641 on the protective cover plate 4.

[0045] The clamping group 64 further includes a telescopic shaft 643 rotatably penetrating and installed at one end of the fitting cylinder 641 away from the pentagonal mounting table 3. A convex platform threaded rod 644 is installed at the telescopic end of the telescopic shaft 643. The convex platform threaded rod 644 is threadedly connected to the threaded section of the fitting cylinder 641. A servo motor 645 is installed on the upper end of the support box 1 through a motor base, and the output shaft of the servo motor 645 is fixedly connected to the telescopic shaft 643.

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

[0047] During specific implementation:

[0048] In this application, the turntable 2 adopts a multi-station continuous processing method. First, the main round tube is sent between the two front abutting conical platforms 523 manually or by an external feeding device. Under the action of the compression spring, the two front abutting conical platforms 523 will jointly support and clamp the main round tube. And at this time, under the anti-friction 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 convex platform abutting rod 62, causing them to retract into the corresponding circular chute one and circular chute two respectively. Then, under the action of the compression spring, the corresponding clamping rod 61 and the convex platform abutting rod 62 will abut against the main round tube to assist in clamping it. Then, the turntable 2 is controlled to rotate intermittently by the intermittent motor 51. The turntable 2 drives the main round tube to rotate clockwise by a proper angle through the two abutting conical platforms 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 the feeding ports.

[0049] When feeding and welding the side circular tubes for the first time, first, the side circular tube conveying and lifting device outside the side feeding docking hole on the left side sequentially conveys multiple side circular tubes to the positions below the corresponding avoidance holes, and conveys the side circular tubes upward to the position at the same horizontal height as the main circular tube. Then, while controlling the upper and lower electromagnets 642 here to start working, the servo motor 645 is used to control the rotation of the connected telescopic shaft 643. At this time, the upper and lower electromagnets 642 jointly magnetically attract the matching cylinder 641 to make it unable to rotate. When the telescopic shaft 643 drives the convex platform threaded rod 644 to rotate, the convex platform threaded rod 644 will gradually screw out towards the pentagonal mounting table 3 under the action of the threaded section on the matching cylinder 641. During this period, the clamping end of the convex platform threaded rod 644 is inserted into the side circular tube and drives it to continue approaching the pentagonal mounting table 3 until the welding end of the side circular tube is closely attached to the outer wall of the main circular tube. Then, 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 circular tube is closely attached to the outer wall of the main circular tube, it will make an adaptive rotational compensation under the thrust of the convex platform threaded rod 644 after contacting the outer wall of the main circular tube, so as to achieve the effect that the welding end of the side circular tube is closely attached to the outer wall of the main circular tube.

[0050] Then, the servo motor 645 is used to control the telescopic shaft 643 to drive the convex platform threaded rod 644 to rotate. Since the convex platform threaded rod 644 has been screwed out to the maximum distance at this time and the matching cylinder 641 can rotate freely, the convex platform threaded rod 644 will drive the matching cylinder 641 to rotate together, and together with the pressing and clamping force of the V-shaped clamping plate magnetically connected to the corresponding clamping rod 61 on the main circular tube, it will jointly drive the main circular tube and the side circular tube to rotate in a circle around the convex platform threaded rod 644. At the same time, an external laser welding head (not shown in the figure) automatically welds the welding line position of the side circular tube and the main circular tube. After the welding is completed, while controlling the upper and lower electromagnets 642 to start working, the servo motor 645 is used to control the telescopic shaft 643 to drive the convex platform threaded rod 644 to rotate in the reverse direction until the convex platform threaded rod 644 retracts into the matching cylinder 641, and then the servo motor 645 stops working. The cooperation of the freely telescopic convex platform threaded rod 644 and the adaptively pressing clamping rod 61 is used, which is stable and convenient for clamping, so as to achieve the effect of driving the main circular tube and the side circular tube to rotate in a circle around the convex platform threaded rod 644 for easy welding.

[0051] When flipping, the intermittent rotation of the turntable 2 is then 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 slide groove 632. The positions of the two semi-annular slide grooves on the guide slide groove 632 correspond to the positions of the contact plate 635 and the material guide slide plate 41 respectively. At this time, the counterweight slide 633 corresponding to the contact plate 635 will slide along the guide slide groove 632. When the counterweight slide 633 slides into the corresponding semi-annular slide groove, this counterweight slide 633 will drive the annular slide 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 of the counterweight slide 633 itself, it will slide compensation along the matching inclined groove on the corresponding clamping rod 61, thereby achieving the effect of squeezing the clamping rod 61 back into the corresponding circular slide groove.

[0052] While the turntable 2 drives the main tube to rotate clockwise at a suitable angle through the two abutting cones 523, the side tube welded on the main 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 tube will drive the main tube to make adaptive rotation compensation around the corresponding supporting vertical plate 522, and under the action of gravity, the side tube will gradually turn 180 degrees toward one side of the pentagonal mounting platform 3 and fit the upper end of the wedge-shaped supporting plate 636, and this side tube is still in the same 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 tube 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 rotate upward synchronously with 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 surface 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 externally provided at the right side feeding docking hole conveys multiple side tubes to the corresponding avoidance holes in turn, and conveys 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 in a circle around the boss threaded rod 644, and the external laser welding head (not shown in the drawings) here automatically welds the side tube and the main tube at the welding line position. When welding is completed, through the cooperation of the upper and lower electromagnets 642 and the servo motor 645, the boss threaded rod 644 is controlled to retract into the matching tube 641, and the servo motor 645 stops working, thereby achieving the effect of welding two side tubes in turn, avoiding the cumbersome operation of manually clamping the main tube and the side tube repeatedly, and effectively improving the welding work efficiency.

[0054] When discharging the welded main circular tube, the intermittent motor 51 is used to control the intermittent rotation of the turntable 2 again. The welded main circular tube moves to a position corresponding to the material guiding slide plate 41. At this time, the counterweight slide rod 633 corresponding to the material guiding slide plate 41 slides along the guiding chute 632. When the counterweight slide rod 633 slides into the corresponding semi-circular chute, the counterweight slide rod 633 will drive the annular sliding sleeve to slide along the corresponding kidney-shaped slide hole towards the side close to the pentagonal mounting table 3. Under the action of the gravity of its own counterweight, the counterweight slide rod 633 makes a sliding compensation along the matching inclined groove on the corresponding clamping rod 61, so as to realize the effect of extruding the clamping rod 61 to extend out of the corresponding circular chute I. At this time, the corresponding clamping rod 61 will push the welded main circular tube, so that it breaks away from the limit clamping of the corresponding two abutting cone platforms 523. Under the action of the compression spring, the boss abutting rod 62 will push the corresponding side circular tube on this main circular tube again to ensure that it is pushed onto the material guiding slide plate 41 and slides out from the material guiding slide plate 41. Similarly, when the intermittent motor 51 is used to control the intermittent rotation of the turntable 2 next time, the counterweight slide rod 633 corresponding to the above-mentioned material guiding slide plate 41 will continue to slide along the guiding chute 632 and withdraw from the corresponding semi-circular chute. The counterweight slide rod 633 will drive the annular sliding sleeve to slide along the corresponding kidney-shaped slide hole towards the side away from the pentagonal mounting table 3 to return to its original position, and the counterweight slide rod 633 will make a sliding compensation along the matching inclined groove on the corresponding clamping rod 61 to return to its original position.

[0055] When it is necessary to adjust the welding position of the main circular tube and the side circular tube, an operator manually rotates a plurality of adjusting wheels 527 in sequence. Under the transmission action of the second bevel gear 526 and the first bevel gear 525, the corresponding lead screw 521 will be driven to rotate, so as to realize the effect of adjusting the positions of the corresponding two support vertical plates 522 through the lead screw 521. That is, the welding position between the main circular tube and the two side circular tubes can be freely adjusted within the working range of the T-shaped hole according to actual needs, and the multi-degree-of-freedom laser welding head can be adapted without affecting all the above work processes.

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

[0057] Advantage 1: In the present application, a multi-station continuous processing method is adopted. First, the main circular tube is supported and clamped jointly by the two abutting cone platforms 523 on the front side. Then, the intermittent motor 51 is used to control the intermittent rotation of the turntable 2. The turntable 2 drives the main circular tube to rotate clockwise by a suitable angle through the two abutting cone platforms 523, so that it is located directly above the adjacent avoidance hole on the left. Then, the side circular tube feeding and lifting device outside the side feeding and docking hole on the left performs the feeding work of the side circular tube. Finally, through the cooperation of the upper and lower electromagnets 642 and the servo motor 645, and through the cooperation of the telescopable boss threaded rod 644 and the adaptively abutting clamping rod 61, the clamping is firm and convenient, so as to realize the effect of driving the main circular tube and the side circular tube to rotate around the boss threaded rod 644 for welding.

[0058] Advantage two: When flipping, after the turntable 2 rotates intermittently, the counterweight slide bar 633 corresponding to the contact plate 635 will slide along the guiding chute 632. After the counterweight slide bar 633 slides into the corresponding semi-circular chute, this counterweight slide bar 633 will drive the annular slide sleeve to slide away from the pentagonal mounting table 3 along the corresponding kidney-shaped slide hole, and under the gravity of the counterweight of the counterweight slide bar 633 itself, it will make a sliding compensation along the mating inclined groove on the corresponding clamping rod 61, so as to achieve the effect of squeezing the clamping rod 61 to retract into the corresponding circular chute one.

[0059] Advantage three: At the same time, the side circular tube welded on the main circular tube will slide along the upper surface of the spiral slide plate 634 and drive the main circular tube to make an adaptive rotation compensation around the corresponding support vertical plate 522 until it gradually flips 180 degrees and fits against the upper end of the wedge-shaped support plate 636 to complete the flipping work. After the turntable 2 rotates intermittently again, the counterweight slide bar 633 at the corresponding contact plate 635 will continue to slide along the guiding chute 632 and withdraw from the corresponding semi-circular chute. This counterweight slide bar 633 will drive the annular slide sleeve to slide towards the side close to the pentagonal mounting table 3 along the corresponding kidney-shaped slide hole to return to its original position, and the counterweight slide bar 633 will make a sliding compensation along the mating inclined groove on the corresponding clamping rod 61 to return to its original position, so as to achieve the effect of clamping and holding the main circular tube and the welded side circular tube tightly by the clamping rod 61 and the boss clamping rod 62 respectively.

[0060] Advantage four: When the secondary side circular tube is loaded and welded, the secondary side circular tube loading work is carried out by the side circular tube conveying and lifting device arranged outside the right feeding docking hole. Similarly, through the cooperation of the upper and lower two electromagnets 642 and the servo motor 645, the boss threaded rod 644 and the V-shaped clamping plate magnetically connected to the clamping rod 61 with adaptive clamping here will also drive the main circular tube and the side circular tube to make a circular rotation around the boss threaded rod 644 together, and the automatic welding is carried out at the welding line position of the side circular tube and the main circular tube by the externally arranged laser welding head (not shown in the figure), so as to achieve the effect of welding two side circular tubes in sequence and avoid the problem of the cumbersome operation of manually repeatedly clamping the main circular tube and the side circular tube.

[0061] Advantage 5: 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 material guide slide 41. The counterweight slide bar 633 corresponding to the material guide slide 41 will slide along the guide slide groove 632. When the counterweight slide bar 633 slides into the corresponding semi-annular slide groove, the counterweight slide bar 633 will drive the annular sliding sleeve to slide along the corresponding waist-shaped sliding hole toward the side close to the pentagonal mounting platform 3, and under the action of the gravity of the counterweight of the counterweight slide bar 633 itself, it will slide along the corresponding clamping rod 61. The cooperating inclined groove is used for 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 abutting cones 523, and the boss abutting rod 62 will push the corresponding side round tube for a 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 and the welding work efficiency is effectively improved.

[0062] Advantage six, 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, and 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 positions of the corresponding two supporting plates 522 through the screw 521, and 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.
