Description

Technical Field

[0001] This invention relates to the field of steel structure component welding technology, and in particular to a steel structure component displacement welding machine assembly. Background Technology

[0002] The position welding machine integrates a fixture for fixing the workpiece and a positioner for moving and rotating the workpiece. By precisely controlling the position and orientation of the workpiece, the weld is placed in the most ideal position, usually flat or sculpted, thus significantly improving welding quality and production efficiency.

[0003] Currently, the most common type is the C-type welding positioner. Its main structure includes a C-shaped frame, a main spindle head drive side, and a tailstock driven side. Before operation, the workpiece is clamped. During operation, the C-type welding positioner rotates, presenting each position of the weld seam to the most ideal flat welding position in sequence. The welding robot then moves in coordination to perform the welding operation. However, the C-shaped structure of the C-type welding positioner is essentially a non-closed cantilever beam. Compared with a closed positioner, its torsional and bending resistance is weaker. When the worktable carries a heavy workpiece and rotates or tilts, the huge torque and bending moment will all be concentrated at the opening of the C-shape, which can easily cause elastic deformation of the C-arm, affecting the stability of the workpiece during welding. Secondly, when the clamped workpiece is irregularly shaped, or when the clamped workpiece is regular in shape but its center of gravity is far from the rotation center, a huge eccentric moment will be generated. This will not only put a huge load on the drive motor and reducer, causing overheating or damage, but will also generate vibration during rotation, thus affecting the stability of the welding process.

[0004] Therefore, in order to improve the stability of workpiece welding and enhance welding quality, this invention provides a displacement welding machine assembly for steel structure components. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art, and to propose a steel structure component displacement welding machine assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel structure component displacement welding machine assembly, including a track base, on which two U-shaped support bases are arranged on the left and right sides. The left U-shaped support base is fixedly connected to the track base, and the right U-shaped support base is slidably connected to the track base on the left and right sides through a screw transmission mechanism. A C-shaped slide is rotatably connected to the U-shaped support base through a gear transmission mechanism. The C-shaped slide has a rectangular slot one and a rectangular slot two. The rectangular slot one is for placing the workpiece to be processed, and the rectangular slot two is provided with a clamping part.

[0007] The C-shaped carriage is provided with a reinforcing part, which includes an inverted L-shaped frame on which the side walls of the two C-shaped carriages are slidably mounted up and down through a screw drive mechanism. The inverted L-shaped frame is provided with a feed drive component and a locking component. The feed drive component is provided with a vibration damping component and a rotation drive component.

[0008] The C-shaped carriage and clamping part work together to clamp the ends of the workpiece to be processed from four directions: top, bottom, front, and back. The feed drive drives the locking part to further lock the clamping part and the clamped workpiece from two positions: top and bottom. The feed drive, locking part and C-shaped carriage work together to clamp the workpiece to be processed from two dimensions: longitudinal and transverse. The vibration damping part buffers and reduces vibration when the two ends of the workpiece are displaced during welding.

[0009] In the above-mentioned steel structure component displacement welding machine assembly, the clamping part includes a hydraulic rod 1, and extension plates are symmetrically fixed on the left and right side walls of the C-shaped slide. Hydraulic rod 1 is installed in the middle of each of the two extension plates, and the telescopic ends of the two hydraulic rod 1 are jointly fixed with a clamping plate that slides in the rectangular slot 2.

[0010] In the aforementioned steel structure component displacement welding machine assembly, the top wall of the clamping plate is fixedly connected with four limiting rods distributed in a matrix. The limiting rods slide up and down through the corresponding extension plates, and the bottom wall of the clamping plate is symmetrically connected with locking rods via an electric slider.

[0011] In the above-mentioned steel structure component displacement welding machine assembly, the feed drive component includes a hydraulic rod two, and the hydraulic rod two is installed on the vertical section of the inverted L-shaped frame. The telescopic end of the hydraulic rod two is fixedly connected to a support plate. The support plate is fixedly connected to a balance bar in a matrix shape on the side near the vertical section of the inverted L-shaped frame, and the balance bar slides through the vertical section of the inverted L-shaped frame.

[0012] In the above-mentioned steel structure component displacement welding machine assembly, the locking component includes an L-shaped locking frame, and the top of the support plate is symmetrically fixed with an L-shaped locking frame at the front and back. The front and rear parts of the support plate are symmetrically fixed with an L-shaped pushing frame. The horizontal section of the inverted L-shaped frame has a sliding groove symmetrically opened on the front and rear side walls, and the horizontal section of the L-shaped pushing frame is slidably connected to the sliding groove at the left and right.

[0013] In the above-mentioned steel structure component displacement welding machine assembly, the horizontal section of the inverted L-shaped frame near the C-shaped slide is symmetrically fixed with a limiting frame corresponding to the limiting rod, and a locking block is slidably connected to the limiting frame by a spring. The side wall of the locking block inside the limiting frame is serrated, and the lower part of the locking rod near the locking block is serrated to match the locking block.

[0014] In the above-mentioned steel structure component displacement welding machine assembly, the vibration damping component includes a second slide groove, and four slide grooves are provided on the outer wall of the support plate away from the hydraulic rod second along the circumferential direction. A T-shaped adjustment seat is radially slidably connected to the slide groove second by a spring second, and a fixing plate is fixedly connected to the middle of the side of the T-shaped adjustment seat away from the support plate.

[0015] In the above-mentioned steel structure component displacement welding machine assembly, the T-shaped adjusting seat has an arc-shaped sliding groove three symmetrically opened on the side away from the support plate. The sliding groove three is slidably connected to a movable plate that is hinged to the fixed plate by an electric slider two. Both the fixed plate and the movable plate are symmetrically connected to contact plates by spring three.

[0016] In the above-mentioned steel structure component displacement welding machine assembly, the rotating drive component includes a toothed ring, and the toothed ring is rotatably connected inside the support disk. The inner ring wall of the toothed ring is fixedly connected with a wedge block corresponding to the slide groove two along the circumferential direction.

[0017] In the above-mentioned steel structure component displacement welding machine assembly, the side of wedge one away from the toothed ring is inclined, and wedge two is fixedly connected to the T-shaped adjustment seat, and the outer wall of the side of wedge two away from the T-shaped adjustment seat is inclined to match wedge one.

[0018] Compared with existing technologies, the advantages of this invention are as follows: 1. By cooperating with the C-shaped carriage, clamping part and reinforcing part, the workpiece to be processed is limited and clamped, and the positions of the clamping part and the workpiece to be processed are locked, increasing the clamping stability of the C-shaped carriage and clamping part; the clamping plate and the pad of the C-shaped carriage limit and clamp the workpiece to be processed from the upper and lower directions; after the two locking rods move down, they limit and clamp the workpiece to be processed from the front and rear directions; the L-shaped locking frame clamping plate is driven to limit and press up; the serrated sidewall of the locking block and the serrated sidewall of the locking rod engage to lock the position of the locking rod.

[0019] 2. The C-shaped carriage and clamping plate clamp the workpiece longitudinally from both ends. The L-shaped locking frame, support plate and L-shaped pushing frame form a C-shaped structure, which provides lateral support to the C-shaped carriage from the left and right sides respectively. By providing encircling support to the workpiece from both longitudinal and lateral dimensions, the lateral support can also effectively prevent the C-shaped carriage from elastically deforming, further improving the stability of clamping.

[0020] 3. When the workpiece rotates or tilts during processing, its center of gravity moves away from the rotation center. The contact plate and spring will absorb some of the eccentric torque, which causes vibrations in the C-shaped carriage and clamping part. The vibration damping effect of the damping component, together with the rigid support and clamping of the C-shaped carriage and clamping part, improves the stability during welding processing, thereby improving the quality of welding.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figures 1 to 2 A steel structure component displacement welding machine assembly includes a track base 1, on which two U-shaped support seats 2 are arranged on the left and right sides. The left U-shaped support seat 2 is fixedly connected to the track base 1, and the right U-shaped support seat 2 is slidably connected to the track base 1 through a screw transmission mechanism (not shown in the figure, and the screw transmission mechanism is an existing mature technology, which will not be described in detail here). A C-shaped slide 3 is rotatably connected to the U-shaped support seat 2 through a gear transmission mechanism (not shown in the figure, and the gear transmission mechanism is an existing mature technology, which will not be described in detail here). The C-shaped slide 3 has a rectangular slot 1 and a rectangular slot 2. The rectangular slot 1 is for placing the workpiece to be processed, and the rectangular slot 2 is provided with a clamping part 4.

[0038] Reference Figure 1 , Figure 2 and Figure 8 The C-shaped carriage 3 is provided with a reinforcing part 5. The reinforcing part 5 includes an inverted L-shaped frame 51 on which the side walls of the two C-shaped carriages 3 are slidably mounted up and down through a screw drive mechanism (not shown in the figure). The inverted L-shaped frame 51 is provided with a feed drive component 52 and a locking component 53. The locking component 53 is used to lock the position of the clamping part 4 and the workpiece. The feed drive component 52 is provided with a vibration damping component 54 and a rotation drive component 55. The vibration damping component 54 is used to buffer and dampen the vibration at both ends of the workpiece to be processed.

[0039] This invention can cooperate with an external welding robot (not shown in the figure, and the welding robot is a mature existing technology, which will not be described in detail here) to perform displacement welding on tubular and shaft-type steel structural components to be processed, including square and round tubular components and square and round shaft-type components, and can stably clamp and weld eccentric workpieces with regular shapes but whose center of gravity is far from the center of rotation.

[0040] The U-shaped support 2 on the right side drives the C-shaped carriage 3 to slide left and right on the track seat 1 through the lead screw transmission mechanism, so as to adjust it to move closer to or further away from the U-shaped support 2 on the left side according to the length of the workpiece to be processed; both ends of the workpiece to be processed are placed in the corresponding C-shaped carriage 3, and the clamping part 4 is adjusted. The clamping part 4 and the C-shaped carriage 3 cooperate to clamp the ends of the workpiece to be processed from four directions: up, down, front, and back; the feed drive 52 drives the locking part 53 to further lock the clamping part 4 and the clamped workpiece to be processed from two directions: up and down. The feed drive 52, the locking part 53 and the C-shaped carriage 3 cooperate to surround the workpiece to be processed from two dimensions: longitudinal and transverse. The feed drive 52 drives the vibration damping part 54 to move closer to the workpiece to be processed, and the rotation drive 55 drives the vibration damping part 54 to change shape, so as to buffer and dampen the two ends of the workpiece to be processed.

[0041] After the material is unloaded and clamped, the corresponding C-shaped carriage 3 and the workpiece to be processed are rotated and repositioned through the gear transmission mechanism, and then cooperate with the external welding robot to perform welding processing.

[0042] Reference Figures 2 to 3 The clamping part 4 includes a hydraulic rod 41. Extension plates are symmetrically fixed on the left and right side walls of the C-shaped slide 3. Hydraulic rods 41 are installed in the middle of the two extension plates. The telescopic ends of the two hydraulic rods 41 are fixed to a clamping plate 42 that slides in the rectangular slot 2. The top wall of the clamping plate 42 is fixedly connected to four limiting rods 43 distributed in a matrix through a connecting plate. The limiting rods 43 slide up and down through the corresponding extension plates. The bottom wall of the clamping plate 42 is symmetrically connected to a locking rod 44 through an electric slider.

[0043] The initial position of the C-shaped carriage 3 is with the rectangular slot facing directly forward. A pad is installed on the rectangular slot. Both ends of the workpiece to be processed are placed on the pads in the corresponding rectangular slots of the C-shaped carriage 3. At this time, the clamping part 4 is directly above the workpiece. The locking rod 44 is adjusted in position by the electric slider according to the diameter or front-to-back distance of the workpiece. During clamping operations, the telescopic end of the hydraulic rod 41 drives the clamping plate 42 and the locking rod 44 downwards. When the clamping plate 42 moves downwards, the limiting rod 43 is used to maintain the stability of the clamping plate 42 until the clamping plate 42 presses against the top wall of the workpiece. The clamping plate 42 and the pads of the C-shaped carriage 3 limit and clamp the workpiece from both above and below. After the two locking rods 44 move downwards, they limit the workpiece from both the front and back.

[0044] Reference Figure 2 and Figure 4 The feed drive component 52 includes a second hydraulic rod 521. The second hydraulic rod 521 is installed on the vertical section of the inverted L-shaped frame 51. The telescopic end of the second hydraulic rod 521 is fixedly connected to a support plate 522. The support plate 522 is fixedly connected to a balance bar 523 in a matrix shape on the side of the support plate 522 near the vertical section of the inverted L-shaped frame 51. The balance bar 523 slides through the vertical section of the inverted L-shaped frame 51.

[0045] Reference Figures 2 to 6 The locking component 53 includes an L-shaped locking frame 531. The top of the support plate 522 is symmetrically fixed with an L-shaped locking frame 531. The front and rear parts of the support plate 522 are symmetrically fixed with an L-shaped pushing frame 533. The horizontal section of the inverted L-shaped frame 51 has symmetrically opened sliding grooves 532 on its front and rear side walls. The horizontal section of the L-shaped pushing frame 533 is slidably connected to the sliding grooves 532. The horizontal section of the inverted L-shaped frame 51 near the C-shaped slide 3 is symmetrically fixed with a limiting frame 534 corresponding to the locking rod 44. A locking block 535 is slidably connected to the limiting frame 534 by a spring (not shown in the figure). The locking block 535 is set in the side wall inside the limiting frame 534 in a sawtooth shape. The lower part of the locking rod 44 near the locking block 535 is in a sawtooth shape that matches the locking block 535.

[0046] Reference Figure 2 , Figure 7 and Figure 9The damping component 54 includes a second slide groove 541. Four slide grooves 541 are provided on the outer wall of the support plate 522 away from the hydraulic rod 521 along the circumferential direction. A T-shaped adjusting seat 542 is radially slidably connected to the slide groove 541 by a spring 2 (not shown in the figure). A fixing plate 544 is fixedly connected to the middle of the side of the T-shaped adjusting seat 542 away from the support plate 522. A third arc-shaped slide groove 543 is symmetrically provided on the side of the T-shaped adjusting seat 542 away from the support plate 522. A movable plate 545 is slidably connected to the slide groove 543 and hinged to the fixing plate 544 by an electric slider 2. A contact plate 546 is symmetrically connected to both the fixing plate 544 and the movable plate 545 by a spring 3.

[0047] Reference Figures 7 to 8 The rotating drive component 55 includes a gear ring 551. The gear ring 551 is rotatably connected inside the support disk 522. The inner ring wall of the gear ring 551 is fixedly connected to a wedge block 552 corresponding to the slide groove 541 along the circumferential direction. The side of the wedge block 552 away from the gear ring 551 is inclined. The T-shaped adjusting seat 542 is fixedly connected to a wedge block 553. The outer wall of the side of the wedge block 553 away from the T-shaped adjusting seat 542 is inclined to match the wedge block 552.

[0048] The inverted L-shaped frame 51 is adjusted up and down synchronously according to the height of the clamping plate 42 through the second lead screw transmission mechanism so that the support plate 522 is coaxial with the workpiece to be processed. After the clamping part 4 is adjusted, the lower part of the locking rod 44 with serrated edges is inserted into the corresponding limit frame 534.

[0049] The telescopic end of hydraulic rod 521 drives support plate 522 to move closer to the end of the workpiece to be processed. As support plate 522 moves, balance rod 523 is used to maintain its stability. Support plate 522 drives L-shaped locking frame 531 to move to the top wall of clamping plate 42 and performs limiting clamping from above clamping plate 42 (e.g., ...). Figure 2 (As shown). The support plate 522 drives the L-shaped pusher 533 to slide on the slide groove 532 and slide closer to the locking block 535. The spring connecting the limiting frame 534 and the locking block 535 is stretched until the pushing locking block 535 approaches the locking rod 44 in the corresponding limiting frame 534 (as shown). Figure 5 and Figure 6 As shown, the serrated sidewall of the locking block 535 engages with the serrated sidewall of the locking rod 44 to lock the position of the locking rod 44 and increase the clamping stability of the clamping part 4.

[0050] The C-shaped carriage 3 and the clamping plate 42 clamp the workpiece longitudinally from the outside of both ends. The L-shaped locking frame 531, the support plate 522 and the L-shaped pushing frame 533 form a C-shaped structure, which provides lateral support to the C-shaped carriage 3 from the left and right sides respectively. By providing encircling support to the workpiece from both longitudinal and lateral dimensions, the lateral support can effectively prevent the C-shaped carriage 3 from elastically deforming, further improving the stability of clamping.

[0051] It should be noted that the support plate 522 has a slot for the toothed ring 551 and the wedge 552 to rotate, and the support plate 522 is a detachable structure. The support plate 522 is equipped with a forward and reverse motor. The output end of the forward and reverse motor is fixedly connected to a gear, which meshes with the toothed ring 551. The forward and reverse motor drives the gear to rotate, thereby driving the toothed ring 551 to rotate.

[0052] The rotation of the gear ring 551 drives the first wedge 552 to move. When the first wedge 552 moves, its inclined surface pushes against the inclined surface of the corresponding second wedge 553. The second wedge 553 drives the T-shaped adjusting seat 542 to slide on the corresponding slide groove 541. In this way, the forward and reverse rotation of the forward and reverse motors and the compression and reset of the second spring control the four T-shaped adjusting seats 542 to move closer or further apart from each other.

[0053] When machining a tubular workpiece, the four T-shaped adjusting seats 542 move closer together and enter the interior of the end of the tubular workpiece. The positions of the four T-shaped adjusting seats 542 are adjusted by rotating the forward and reverse motors until the outermost contact plate 546 is in contact with the inner wall of the tubular workpiece. For example, this is used for vibration damping operations on square tubular components (such as...). Figure 10 As shown), vibration reduction work for circular pipe fittings (such as...) Figure 12 (As shown).

[0054] When machining a shaft-type workpiece, the four T-shaped adjusting seats 542 move away from each other, extending to the outside of the workpiece. The positions of the four T-shaped adjusting seats 542 are adjusted by rotating a forward and reverse motor. Simultaneously, the electric slider two drives the corresponding movable plate 545 to slide on the slide groove three 543. The movable plate 545 deflects around the axis hinged to the fixed plate 544 until the inner contact plate 546 contacts the outer wall of the shaft-type workpiece. For example, this is used for vibration damping operations on square shafts (such as...). Figure 11 As shown), vibration reduction work for circular shafts (such as...) Figure 13 (As shown).

[0055] It should be noted that the fixed plate 544 and the two movable plates 545 on the same T-shaped adjusting seat 542 are initially aligned, and the three contact plates 546 on the same side are evenly distributed.

[0056] The contact plate 546 and the corresponding fixed plate 544 and movable plate 545 are connected by a spring three, which is a vibration damping spring. When the machining process involves rotation or tilting, the center of gravity of the workpiece moves away from the rotation center. The contact plate 546 and the spring three absorb part of the eccentric torque that causes vibrations in the C-shaped slide 3, the clamping part 4, and the workpiece. The vibration damping effect of the damping component 54, combined with the rigid support and clamping of the C-shaped slide 3 and the clamping part 4, improves the stability during welding processing, thereby improving the welding quality.

[0057] It should be noted that when processing tubular or round shaft workpieces, although the contact plate 546 cannot completely fit the inner or outer wall of the workpiece, it can make contact at multiple points and thus achieve a vibration reduction effect.

[0058] In this invention, the clamping part 4 limits and clamps the workpiece to be processed from four directions: up, down, front, and back. The locking part 53 locks the positions of the clamping part 4 and the workpiece to be processed. Then, the C-shaped carriage 3 and the clamping plate 42, together with the C-shaped structure formed by the driving part 52 and the locking part 53, provide a surrounding clamping of the workpiece to be processed from both longitudinal and transverse dimensions, further improving the stability of the clamping. Finally, the vibration damping effect of the damping part 54, combined with the rigid support clamping of the C-shaped carriage 3 and the clamping part 4, improves the stability during welding. Although this invention adds a reinforcing part 5 compared to the prior art, it increases the stability of welding from multiple directions, thereby improving the quality of welding. From a long-term economic perspective, the equipment cost of the added structure of this invention is negligible compared to the prior art.
