Description

Technical Field

[0001] This utility model relates to the field of pulsed submerged arc welding technology, specifically to a medium-thick plate welding equipment based on pulsed submerged arc welding. Background Technology

[0002] Medium-thick plates refer to steel plates with a thickness ranging from 4.5 to 25.0 mm. Plates with a thickness of 25.0 to 100.0 mm are called thick plates, and those with a thickness exceeding 100.0 mm are called extra-thick plates. Medium-thick plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, and bridge construction. Welding technology, also known as joining engineering, is an important material processing technology. Welding is defined as follows: the process of permanently joining workpieces (of the same or different materials) by heating or pressurizing, or both, with or without filler material, to achieve atomic bonding between the materials of the workpieces. In engineering applications, welding of medium-thick plates is required according to usage requirements. Existing longitudinal seam welding machines can perform high-quality welding of welds with regular straight lines.

[0003] However, existing medium and heavy plate welding equipment is prone to errors in the processing of medium and heavy plates due to manual operation, which may affect the performance of the equipment, cause accidents, or reduce its service life. Therefore, there is an urgent need for a medium and heavy plate welding equipment based on pulsed submerged arc welding. Utility Model Content

[0005] The purpose of this invention is to provide a medium-thick plate welding equipment based on pulse submerged arc welding, so as to solve the problem mentioned in the background art that the components are prone to errors due to manual operation.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a medium-thick plate welding equipment based on pulse submerged arc welding, comprising a worktable, equipment seats slidably mounted on the left and right sides of the upper end face of the worktable, mounting seats fixedly mounted on the side walls of the equipment seats, a clamping mechanism provided in the inner cavity of the mounting seats, upright plates fixedly mounted on the left and right sides of the upper end face of the worktable, an adjustment mechanism provided between the upright plates on the left and right sides, and a gantry frame fixedly mounted in the middle of the upper end face of the worktable, with a welding mechanism provided in the inner cavity of the gantry frame.

[0008] Preferably, the clamping mechanism includes clamping gears rotatably mounted on the front and rear sides of the inner cavity of the mounting base, and a clamping rack meshing between the clamping gears on the front and rear sides. A first connecting rod is fixedly mounted on the side wall of the clamping gears, and a second connecting rod is rotatably mounted on the inner cavity of the mounting base. A clamping rod is rotatably mounted on the other end of the second connecting rod.

[0009] Preferably, the clamping rod has a first node and a second node on its side wall, the second connecting rod is rotatably mounted at the second node, and the first connecting rod is rotatably mounted at the first node.

[0010] Preferably, a clamping motor is fixedly installed in the inner cavity of the device base, a clamping screw is fixedly installed at the output shaft end of the clamping motor, a connecting plate is threaded on the side wall of the clamping screw, and the connecting plate is fixedly connected to the clamping rack.

[0011] Preferably, the adjustment mechanism includes a bidirectional threaded rod rotatably mounted between the front upright plates, a limit rod fixedly mounted in the inner cavity of the rear upright plate, a transmission worm gear fixedly mounted on the left side wall of the bidirectional threaded rod, a support plate fixedly mounted on the front side of the upper end of the worktable, and a transmission worm gear rotatably mounted in the inner cavity of the support plate.

[0012] Preferably, an adjusting motor is fixedly mounted on the upper surface of the workbench via a frame. The output shaft of the adjusting motor is fixedly connected to a transmission worm gear, which meshes with a transmission worm wheel. The equipment base is threadedly connected to a bidirectional threaded rod, with the left and right sides of the bidirectional threaded rod having opposite thread directions. The equipment base is slidably connected to a limiting rod.

[0013] Preferably, the welding mechanism includes a lead screw rotatably mounted inside the gantry frame, a welding motor fixedly mounted on the side wall of the gantry frame via a frame, the output shaft end of the welding motor being fixedly connected to the lead screw, a sliding seat threaded onto the side wall of the lead screw, a welding machine fixedly mounted on the lower end face of the sliding seat, a sliding groove formed on the side wall of the gantry frame, a sliding rod slidably mounted inside the sliding groove, and the sliding rod being fixedly mounted on the side wall of the sliding seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention allows for the operation of an adjusting motor based on the length of the medium-thick plate. The adjusting motor drives the transmission worm gear, causing it to rotate. Since the transmission worm gear meshes with the transmission worm wheel, it drives a bidirectional threaded rod to rotate. Because the threads on the left and right sides of the bidirectional threaded rod are opposite, the mounting seats on both sides can move closer simultaneously. The worker can then start the clamping motor, causing the clamping screw to rotate. Since the clamping screw is threadedly connected to the connecting plate, the connecting plate can drive the clamping rack to move left and right. Because the clamping rack meshes with the clamping gears, the clamping gears on the front and rear sides can drive the first connecting rod to rotate in opposite directions. With the cooperation of the second connecting rod, the clamping plates on the front and rear sides can move closer together, achieving stable clamping of the medium-thick plate and greatly improving the efficiency and quality of welding medium-thick plates using the entire device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution for a medium-thick plate welding equipment based on pulse submerged arc welding: A medium-thick plate welding equipment based on pulse submerged arc welding includes a worktable 1, equipment seats 2 are slidably installed on the left and right sides of the upper end face of the worktable 1, mounting seats 3 are fixedly installed on the side walls of the equipment seats 2, a clamping mechanism 4 is provided in the inner cavity of the mounting seats 3, upright plates 5 are fixedly installed on the left and right sides of the upper end face of the worktable 1, an adjustment mechanism 6 is provided between the upright plates 5 on the left and right sides, and a gantry frame 7 is fixedly installed in the middle of the upper end face of the worktable 1, a welding mechanism 8 is provided in the inner cavity of the gantry frame 7.

[0024] Furthermore, the clamping mechanism 4 includes clamping gears 41 rotatably mounted on the front and rear sides of the inner cavity of the mounting base 3, and clamping racks 42 meshing between the clamping gears 41 on the front and rear sides. A first connecting rod 43 is fixedly mounted on the side wall of the clamping gears 41. A second connecting rod 44 is also rotatably mounted in the inner cavity of the mounting base 3. A clamping rod 45 is rotatably mounted on the other end of the second connecting rod 44.

[0025] The clamping rod 45 has a first node 451 and a second node 452 on its side wall. The second connecting rod 44 is rotatably installed at the second node 452, and the first connecting rod 43 is rotatably installed at the first node 451.

[0026] A clamping motor 46 is fixedly installed in the inner cavity of the equipment base 2. A clamping screw 47 is fixedly installed on the output shaft end of the clamping motor 46. A connecting plate 48 is threaded on the side wall of the clamping screw 47. The connecting plate 48 is fixedly connected to the clamping rack 42.

[0027] It should be noted that the worker can start the clamping motor 46 to make the clamping screw 47 rotate. Since the clamping screw 47 is threadedly connected to the connecting plate 48, the connecting plate 48 can drive the clamping rack 42 to move left and right. Since the clamping rack 42 is meshed with the clamping gear 41, the clamping gears 41 on the front and rear sides can drive the first connecting rod 43 to rotate in opposite directions. With the cooperation of the second connecting rod 44, the clamping plates 45 on the front and rear sides can move closer to each other to achieve stable clamping of the medium-thick plate.

[0028] Furthermore, the adjustment mechanism 6 includes a bidirectional threaded rod 61 rotatably mounted between the front upright plates 5, a limit rod 62 fixedly mounted in the inner cavity of the rear upright plate 5, a transmission worm gear 63 fixedly mounted on the left side wall of the bidirectional threaded rod 61, a support plate 64 fixedly mounted on the front side of the upper end face of the worktable 1, and a transmission worm gear 65 rotatably mounted in the inner cavity of the support plate 64.

[0029] An adjusting motor 66 is fixedly mounted on the upper surface of the workbench 1 via a frame. The output shaft of the adjusting motor 66 is fixedly connected to the transmission worm 65. The transmission worm 65 is meshed with the transmission worm wheel 63. The equipment base 2 is threadedly connected to the bidirectional threaded rod 61. The threads on the left and right sides of the bidirectional threaded rod 61 are opposite in direction. The equipment base 2 is slidably connected to the limit rod 62.

[0030] It should be noted that the worker can start the adjustment motor 66 according to the length of the medium and thick plate. At this time, the adjustment motor 66 can drive the transmission worm 65 to make the transmission worm wheel 63 rotate. Since the transmission worm wheel 63 is meshed with the transmission worm wheel 63, the transmission worm wheel 63 can drive the bidirectional threaded rod 61 to rotate. Since the threads on the left and right sides of the bidirectional threaded rod 61 are opposite, the mounting seats 2 on the left and right sides can move closer at the same time.

[0031] Furthermore, the welding mechanism 8 includes a lead screw 81 rotatably mounted inside the gantry 7, a welding motor 82 fixedly mounted on the side wall of the gantry 7 via a frame, the output shaft end of the welding motor 82 being fixedly connected to the lead screw 81, a sliding seat 83 threadedly mounted on the side wall of the lead screw 81, a welding machine 84 fixedly mounted on the lower end face of the sliding seat 83, a sliding groove 71 opened on the side wall of the gantry 7, a sliding rod 72 slidably mounted inside the sliding groove 71, and the sliding rod 72 being fixedly mounted on the side wall of the sliding seat 83.

[0032] Working principle:

[0033] During operation, the worker can start the adjustment motor 66 according to the length of the medium and thick plate. At this time, the adjustment motor 66 can drive the transmission worm 65 to make the transmission worm wheel 63 rotate. Since the transmission worm wheel 63 is meshed with the transmission worm wheel 63, the transmission worm wheel 63 can drive the bidirectional threaded rod 61 to rotate. Since the threads on the left and right sides of the bidirectional threaded rod 61 are opposite, the mounting seats 2 on the left and right sides can move closer at the same time.

[0034] Afterwards, the worker can start the clamping motor 46 to make the clamping screw 47 rotate. Since the clamping screw 47 is threadedly connected to the connecting plate 48, the connecting plate 48 can drive the clamping rack 42 to move left and right. Since the clamping rack 42 is meshed with the clamping gear 41, the clamping gears 41 on the front and rear sides can drive the first connecting rod 43 to rotate in opposite directions. With the cooperation of the second connecting rod 44, the clamping plates 45 on the front and rear sides can move closer to each other to achieve stable clamping of the medium-thick plate.

[0035] After the medium-thick plate is clamped, the worker can start the welding motor 82 to rotate the lead screw 81. Since the lead screw 81 is threadedly connected to the sliding seat 83, under the limiting action of the sliding groove 71 on the sliding rod 72, the sliding seat 83 can drive the welding machine 84 to slide back and forth on the gantry 7, thereby realizing the welding of the medium-thick plate and greatly improving the efficiency and quality of the entire device for welding medium-thick plates.

[0036] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
