Description

Technical Field

[0001] This utility model relates to the field of valve welding technology, and in particular to an automated welding equipment for valve components. Background Technology

[0002] Valves are one of the most widely used fluid control devices. As an important part of pipeline systems, valves come in many specifications and types, and their functions vary. The manufacturing process of valves directly affects the safe operation of pipeline equipment, and valve welding is one of the key processes in valve manufacturing.

[0003] Currently, in existing technologies, when welding valve components with circular cross-sections, the base materials to be welded are assembled according to assembly requirements, and the base materials are fixed in the correct position using tack welding. After the initial fixing of the base material position is completed, filler welding and capping welding are performed on the connection. When welding the valve connection, a three-jaw chuck is used to fix one end of the valve. After fixing, a welding torch is used to weld the valve connection. In order to ensure uniform welding of the connection, the three-jaw chuck is driven to rotate the valve in a circular motion during the welding process.

[0004] However, when using a three-jaw chuck to fix one end of the valve, the valve's own weight will cause the fixing part of the three-jaw chuck to bear a large pressure. In addition, the surface contact between the three-jaw chuck and the valve end is small when the three-jaw chuck is fixed, which cannot guarantee that the valve will rotate stably during the rotation of the three-jaw chuck, thus easily affecting the welding effect of the valve. Utility Model Content

[0005] Therefore, it is necessary to provide an automated welding equipment for valve components to address the problem that the valve's own weight causes the fixed part of the three-jaw chuck to bear a large pressure, and the small contact surface of the three-jaw chuck when fixing the valve cannot guarantee that the valve will rotate stably during the rotation of the three-jaw chuck, which can easily affect the valve welding effect.

[0006] The device includes: a workbench with a welding mechanism mounted on one side; a mounting plate rotatably connected to the upper end of the inner wall of the workbench; a mounting ring rotatably connected to the inner wall of the mounting plate; one end of the mounting ring passing through the mounting plate and fixedly connected to a three-jaw chuck; and a reinforcement mechanism including a fixed rod fixedly connected to the inner wall of the mounting ring; a movable rod slidably connected to the surface of the fixed rod; two round rods slidably connected to the inner wall of the movable rod; one end of each of the two round rods passing through the movable rod and fixedly connected to a reinforcement plate; round blocks fixedly connected to the opposite ends of each of the two round rods; and a spring fixedly connected between one end of each round block and the inner wall of the movable rod.

[0007] In one embodiment, the reinforcement mechanism further includes a rotating rod rotatably connected to the inner wall of the fixed rod. A sliding rod is slidably connected to the inner wall of the rotating rod, and one end of the sliding rod extends through the moving rod and is fixedly connected to a cam. The opposite ends of the two circular blocks are in contact with the surface of the cam. This facilitates driving the two circular rods to push the two reinforcement plates against the inner wall of the valve from two directions.

[0008] In one embodiment, the reinforcement mechanism further includes a locking rod fixedly connected to the inner wall of the rotating rod, and a locking groove is formed on the surface of the sliding rod, with the surface of the locking rod slidably connected to the inner wall of the locking groove. This helps to ensure that the rotating rod rotates synchronously with the sliding rod.

[0009] In one embodiment, the end of the fixed rod away from the moving rod passes through the mounting plate and is fixedly connected to a circular plate. The surface of the circular plate has multiple second threaded holes. One end of the rotating rod passes through the fixed rod and the circular plate and is fixedly connected to a rotating plate. A second bolt is threaded onto the inner wall of the rotating plate. This design facilitates the fixing of the rotating rod, sliding rod, and cam during the initial setup of the device and after the rotating rod has rotated, ensuring the stability of the cam's contact with the two circular blocks. It also facilitates the synchronous rotation of the fixed rod and the rotating rod when the mounting ring drives the fixed rod, thereby ensuring the stability of the device during operation.

[0010] In one embodiment, the upper surface of the fixed rod has multiple evenly distributed first threaded holes, and the inner wall of the movable rod is threaded with a first bolt. This facilitates the fixation of the movable rod and the fixed rod, ensuring the stability of the movable rod during initial rotation, and simultaneously ensuring that the fixed rod rotates synchronously with the movable rod.

[0011] In one embodiment, the surface of the reinforcing plate is curved into an arc shape, and a contact pad is fixedly connected to the outer surface of the reinforcing plate. This helps to increase the friction between the reinforcing plate and the inner wall of the valve when the reinforcing plate is pressed against it, thereby improving the fixing effect of the reinforcing plate when it is pressed against the valve.

[0012] In one embodiment, a rotating rod is fixedly connected to the end of the rotating plate away from the circular plate. This facilitates easier operation by the operator, allowing them to drive the rotating rod more effectively.

[0013] In one embodiment, a limiting rod is fixedly connected to the surface of the slide rod, and the end of the limiting rod away from the slide rod is slidably connected to the inner wall of the moving rod. When the moving rod moves horizontally, it facilitates the synchronous movement of the slide rod, ensuring the stability of the device during use.

[0014] Beneficial effects

[0015] 1. In this solution, by setting the reinforcement mechanism inside the three-jaw chuck, when the three-jaw chuck is used to fix one end of the valve, the fixing rod, the moving rod, and the two reinforcement plates are all located inside the valve. Under the action of the rotating rod, the sliding rod, and the cam, it is beneficial to push the two reinforcement plates to press against the inner wall of the valve from two directions, thereby increasing the contact area when fixing the valve and improving the stability of the valve during circumferential rotation, thus ensuring the welding effect of the valve. Furthermore, under the action of the moving rod and the sliding rod, the reinforcement mechanism is beneficial to adjust the position of the two reinforcement plates according to valves of different lengths, thereby improving the practicality of the device.

[0016] 2. The setting of the second bolt and multiple second threaded holes is beneficial for fixing the rotating rod, sliding rod and cam at the initial stage of the device and after the rotating rod has rotated, ensuring the stability of the cam pressing against the two round blocks. At the same time, it is beneficial for the fixed rod to drive the rotating rod to rotate synchronously when the mounting ring drives the fixed rod, thereby ensuring the stability of the device during operation.

[0031] The following is combined Figures 1-6 This invention describes an automated welding equipment for valve components.

[0032] In one embodiment, an automated welding equipment for valve components includes: a workbench 100, a welding mechanism 200 mounted on one side of the workbench 100, an mounting plate 300 rotatably connected to the upper end of the inner wall of the workbench 100, an mounting ring 400 rotatably connected to the inner wall of the mounting plate 300, one end of the mounting ring 400 penetrating through the mounting plate 300 and fixedly connected to a three-jaw chuck 500; and a reinforcing mechanism 600, including a fixed rod 610 fixedly connected to the inner wall of the mounting ring 400, a movable rod 620 slidably connected to the surface of the fixed rod 610, two round rods 621 slidably connected to the inner wall of the movable rod 620, one end of each of the two round rods 621 penetrating through the movable rod 620 and fixedly connected to a reinforcing plate 624, and round blocks 622 fixedly connected to the opposite ends of the two round rods 621, with a spring 623 fixedly connected between one end of the round block 622 and the inner wall of the movable rod 620.

[0033] In this embodiment, the center of the moving rod 620 coincides with the center of the three-jaw chuck 500, and the two reinforcing plates 624 are symmetrical about the center of the moving rod 620.

[0034] It should be noted that a first low-speed motor is fixedly connected to the other side of the worktable 100. The output shaft of the first low-speed motor is fixedly connected to one side of the mounting plate 300. The first low-speed motor is started by the controller, so that the output shaft of the first low-speed motor drives the mounting plate 300 to rotate clockwise, thereby adjusting the tilt angle of the three-jaw chuck 500.

[0035] A second low-speed motor is fixedly connected to the upper end of the mounting plate 300 on the side away from the three-jaw chuck 500. The output shaft of the second low-speed motor passes through the mounting plate 300 and is fixedly connected to a gear. A gear ring is fixedly connected to the surface of the mounting ring 400. The gear ring meshes with the gear. The second low-speed motor is started by the controller, so that the output shaft of the second low-speed motor drives the gear to rotate, thereby driving the mounting ring 400 and the three-jaw chuck 500 to rotate at low speed through the gear ring.

[0036] When using a three-jaw chuck to clamp valves, the operator drives the large bevel gear to rotate by rotating the small bevel gear on the chuck. The back of the large bevel gear usually has a flat thread structure, which meshes with the flat threads at the rear ends of the three jaws. As the large bevel gear rotates, the three jaws simultaneously move linearly along the radial direction of the chuck body, thereby clamping the workpiece.

[0037] The welding mechanism 200 includes a fixed frame: serving as a basic support structure; a motion mechanism: enabling the movement of the welding torch head to meet the requirements of different welding positions and trajectories; a welding power source: providing the electrical energy required for the welding process, converting AC power into DC or AC power suitable for welding, and outputting stable welding current and voltage; and a welding torch or welding gun: converting the electrical energy output by the welding power source into heat energy, melting the welding wire or welding rod to form a weld.

[0038] The operating principle of the welding mechanism 200 is a known technology and a known welding device. The technical solution of this application is to address the problem of reinforcement during valve welding. Therefore, the internal structure of the welding mechanism 200 is not labeled or described in detail. The welding mechanism 200 is drawn with reference to existing valve welding equipment.

[0039] like Figure 4 As shown, the reinforcement mechanism 600 also includes a rotating rod 630 rotatably connected to the inner wall of the fixed rod 610. The inner wall of the rotating rod 630 is slidably connected to a slide rod 640. One end of the slide rod 640 passes through the moving rod 620 and is fixedly connected to a cam 650. The opposite ends of the two round blocks 622 are in contact with the surface of the cam 650.

[0040] In this embodiment, the two reinforcing plates 624 are symmetrical about the center of the moving rod 620. In the initial state, the opposite ends of the two circular blocks 622 are in contact with the lowest point of the cam 650. As the cam 650 rotates from the lowest point to the highest point and contacts the circular blocks 622, the cam 650 will push the two circular blocks 622 away from each other, and the spring 623 will be compressed.

[0041] like Figure 6 As shown, the reinforcement mechanism 600 also includes a locking rod 631 fixedly connected to the inner wall of the rotating rod 630, and a locking groove 641 is provided on the surface of the sliding rod 640. The surface of the locking rod 631 is slidably connected to the inner wall of the locking groove 641.

[0042] In this embodiment, when the rotating rod 630 is rotated, the sliding rod 640 will be driven to rotate synchronously under the action of the locking rod 631 and the locking groove 641.

[0043] like Figure 3 and Figure 5As shown, the end of the fixed rod 610 away from the moving rod 620 passes through the mounting plate 300 and is fixedly connected to the circular plate 660. The surface of the circular plate 660 is provided with a plurality of second threaded holes 661. One end of the rotating rod 630 passes through the fixed rod 610 and the circular plate 660 and is fixedly connected to the rotating plate 670. The inner wall of the rotating plate 670 is threaded with a second bolt 671.

[0044] In this embodiment, multiple second threaded holes 661 are arranged in a ring, and the distribution range of multiple second threaded holes 661 is between zero and ninety degrees. In the initial state of the device, the second bolt 671 is threadedly connected to one of the threaded holes, thereby fixing the rotating rod 630 through the rotating plate 670, thereby fixing the slide rod 640 and the cam 650, ensuring the stability of the device when the lowest point of the cam 650 contacts the circular block 622 in the initial state.

[0045] like Figure 4 As shown, the upper surface of the fixed rod 610 is provided with a plurality of evenly distributed first threaded holes 611, and the inner wall of the moving rod 620 is threaded with a first bolt 625.

[0046] In this embodiment, in the initial state, the first bolt 625 is threadedly connected to one of the first threaded holes 611, thereby fixing the moving rod 620 and the fixed rod 610 and ensuring the stability of the moving rod 620 in the initial state.

[0047] like Figure 4 As shown, the surface of the reinforcing plate 624 is bent into an arc shape, and a contact pad is fixedly connected to the outer surface of the reinforcing plate 624.

[0048] In this embodiment, the contact pad is a rubber component with high temperature resistance, and the surface of the contact pad has multiple annularly distributed strip grooves. When the reinforcing plate 624 presses against the valve from the inner wall of the valve, the surface of the contact pad contacts the inner wall of the valve.

[0049] like Figure 3 As shown, a rotating rod is fixedly connected to the end of the rotating plate 670 away from the circular plate 660.

[0050] In this embodiment, the surface of the rotating rod is provided with multiple grooves. When the rotating rod 630 needs to be rotated, the operator can drive the rotating rod 630 to rotate by rotating the rod.

[0051] like Figure 4 As shown, a limiting rod 680 is fixedly connected to the surface of the slide rod 640, and the end of the limiting rod 680 away from the slide rod 640 is slidably connected to the inner wall of the moving rod 620.

[0052] In this embodiment, the limiting rod 680 is close to the cam 650, and the inner wall of the moving rod 620 is provided with an annular groove that matches the limiting rod 680. The surface of the limiting rod 680 is slidably connected to the inner wall of the annular groove. When the moving rod 620 moves horizontally, it will drive the slide rod 640 to move synchronously under the action of the annular groove and the limiting rod 680.

[0053] Working principle: When welding the valve, adjust the overall length of the moving rod 620 and the fixed rod 610 according to the required length of the valve to be welded. During adjustment, disconnect the threaded connection between the first bolt 625 and the first threaded hole 611, and pull the moving rod 620 to adjust the overall length. After adjustment, fix the first bolt 625 and the first threaded hole 611 again. After this operation, the operator places one end of the valve into the inside of the three-jaw chuck 500. The fixed rod 610 and the moving rod 620 are located inside the valve, and the three-jaw chuck 500 is driven to fix one end of the valve. After fixing, the operator releases the second bolt 671 from the second threaded hole 661 from the rotating plate 670, and drives the rotating rod 630 to rotate via the rotating rod. The rotating rod 630, slide rod 640, and cam 650 rotate synchronously. During rotation, cam 650 pushes two reinforcing plates 624 away from each other through two round rods 621, so that the two reinforcing plates 624 press against the inner wall of the valve in two directions. After pressing, the second bolt 671 is threaded into the corresponding second threaded hole 661, thereby fixing the rotating rod 630, slide rod 640, and cam 650. After reinforcement, the tilt angle of the valve is adjusted according to welding requirements through mounting plate 300 and three-jaw chuck 500. After adjustment, the mounting ring 400 is driven to rotate, thereby driving the three-jaw chuck 500 and reinforcement mechanism 600 to rotate the valve synchronously, and the welding mechanism 200 is started at the same time to weld the valve connection.

[0054] It should be noted that the low-speed motors and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. The low-speed motor can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
