Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, specifically relating to a welding tooling for long tanks. Background Technology

[0002] A gas storage tank is a pressure vessel used to store compressed gas and balance gas supply and demand. Supports are welded to the side walls of the tank for fixation and to prevent tipping due to vibration. During the welding process, traditional auxiliary methods present inconveniences in fixing the tank and positioning the supports. The tank is prone to rotation during welding, causing the supports to shift, affecting welding accuracy and quality, and impacting subsequent installation.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a welding fixture for long tanks, which fixes the long tanks before welding, improves welding accuracy, ensures welding consistency, improves welding efficiency and quality, and is suitable for mass production.

[0005] Technical Solution: To achieve the above objectives, this utility model provides a welding fixture for a long can, including a base plate. The base plate is rectangular, with a baffle and a support block connected to both ends of its short side. The baffle has a positioning hole, and the top surface of the support block has a V-groove. A long can is mounted on the upper side of the base plate. A positioning device and a pressing device are respectively provided on both sides of the base plate. The pressing device presses and fixes the long can, and the positioning device positions the lug to be welded. The long can is cylindrical, with an air valve connected to one end. The end of the long can away from the air valve is a spherical end face. The spherical end face abuts against the baffle and extends into the positioning hole, coaxially with the positioning hole. The air valve is placed within the V-groove.

[0006] This invention relates to welding lugs for long tanks. During welding, the long tank is placed on the upper side of a base plate. One end of the long tank, with a spherical end face, abuts against a baffle plate and extends into a positioning hole. The air valve is placed in a V-groove on a support block. A pressing device is used to press and fix the long tank to the top surface of the base plate. The lug is then placed between the positioning device and the long tank, and the positioning device positions the lug on the side wall of the long tank. Welding is then performed. This invention fixes the long tank and positions the lug before welding, improving welding precision, ensuring welding consistency, and increasing welding efficiency and quality, making it suitable for mass production.

[0007] Furthermore, in the aforementioned welding fixture for long tanks, a support plate is connected to the top surface of the base plate. The support plate has an arc-shaped cross-section, and the support plate and positioning holes are coaxially arranged. The long tank is placed on the upper side of the support plate. Placing the long tank on the support plate on the top surface of the base plate improves the lateral stability of the long tank and enhances positioning and welding accuracy.

[0008] Furthermore, in the aforementioned welding fixture for the long tank, the pressing device includes a straight plate arranged along the long side of the base plate. The straight plate is connected to the base plate via a column and extends upwards towards the long tank. A sliding sleeve is provided on the side of the straight plate near the long tank, and a hollow tube is connected to the sliding sleeve. The hollow tube is hollow and has a groove on the side near the long tank, with a notch in the middle section of the groove. A pressure rod is slidably connected inside, extending from the lower end of the hollow tube. A pressure block is connected to the lower end of the pressure rod, and the pressure block is rectangular, with its long side arranged along the axis of the long tank. A pressure handle is connected to the upper end of the pressure rod. A flexible rubber strip is provided on the bottom surface of the pressure block, and a positioning protrusion is provided on the pressure rod, which is located within the groove. A spring is fitted on the lower side of the pressure rod, with an integral ring abutting the upper end of the spring and the pressure rod. The lower end of the spring abuts against a ring at the lower opening of the hollow tube. The spring pushes the pressure rod, causing the pressure handle to be at the upper end of the pressure handle. When pressing the long can, turn the lever. The lever pushes the lever to slide downwards along the hollow tube, and the positioning protrusion slides downwards along the groove. When the pressing block presses against the long can, the positioning protrusion is positioned at the notch in the middle of the groove. Rotate the lever to move the positioning protrusion into the notch in the middle of the groove, locking the lever and pressing the long can firmly in place. After welding is complete, rotate the lever in the opposite direction. The positioning protrusion disengages from the notch in the middle of the groove, the spring pushes the lever upwards, and the pressing block disengages from the long can, removing the long can. The pressing device has a simple structure and is easy to operate.

[0009] Furthermore, in the aforementioned welding fixture for long tanks, the positioning device includes positioning plates. Two or more positioning plates are provided, vertically positioned on the side of the long tank furthest from the pressing device. During welding, one side of the support lug abuts against the positioning plate, providing radial positioning for the lug along the long tank. The side of the positioning plate provides axial positioning for the lug along the long tank, improving the positioning accuracy of the lug and thus enhancing welding accuracy and quality.

[0010] Furthermore, in the aforementioned long tank welding fixture, a slide rail is provided on the top surface of the base plate, perpendicular to the axis of the long tank. A push plate is connected to the lower end of the positioning plate, and the positioning plate and the push plate are connected in an L-shape. The push plate is slidably connected to the slide rail via a slider. A transverse drive device is connected to the end of the push plate away from the positioning plate, and the transverse drive device pushes the push plate to move along the slide rail. The transverse drive device drives the positioning plate to slide along the slide rail and positions the positioning plate on one side of the long tank, providing positioning for the welding of the support lugs. When welding is completed, the transverse drive device drives the positioning plate away from the long tank, facilitating the removal of the welded long tank, improving convenience, avoiding collisions with the positioning plate when removing the long tank, which would affect the positioning accuracy of the positioning plate, prevent damage to the long tank, and ensure the quality of the long tank.

[0011] Furthermore, in the aforementioned long tank welding fixture, the transverse drive device includes a connecting plate connected to the base plate, a bushing connected to the connecting plate, a drive rod slidably connected to the bushing, the drive rod and the push plate being driven together, and a handle hinged to the end of the drive rod away from the push plate. The handle has a claw portion, which is integrally set at a right angle to the handle. The handle is hinged to the drive rod via the claw portion, and a connecting piece is hinged at the connection between the claw portion and the handle. The connecting piece is parallel to the claw portion, and the end of the connecting piece away from the handle is hinged to the bushing. When it is necessary to drive the positioning plate to move away from the long tank, the handle is turned, and the handle rotates towards the push plate. The handle drives the claw portion to rotate, and the rotation of the claw portion drives the connecting piece to rotate in the opposite direction, driving the drive rod to move away from the push plate, thereby moving the positioning plate away from the long tank. When it is necessary to push the positioning plate towards the long tank, turn the handle away from the push plate. The handle drives the claw to rotate, which in turn drives the connecting piece to rotate in the opposite direction. This drives the drive rod to move towards the push plate until the hinge points of the claw and connecting piece, the claw and drive rod, and the connecting piece and bushing are in a straight line. At this point, the claw, connecting piece, and drive rod are in the dead zone, and the drive rod is locked. This positions the positioning plate on one side of the long tank and positions the support lug.

[0012] Furthermore, in the aforementioned long tank welding fixture, the air valve includes a valve body, a switch, and an air nozzle. The switch is connected to the side wall of the valve body and controls the valve body's opening and closing. The air nozzle is connected to the side of the valve body away from the long tank and is connected to an air pipe. The valve body has a quadrilateral cross-section, with a V-groove correspondingly provided. The quadrilateral valve body is placed within the V-groove, and the switch is positioned away from the positioning plate. Then, the long tank is pressed and fixed. The quadrilateral valve body prevents the long tank from rotating and limits the relative position of the support lug and the switch, ensuring the switch is positioned away from the limiting support lug.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects: The long can welding fixture of this utility model places the long can on a pallet, improving the lateral stability of the long can. The pressing device fixes the long can, and the positioning device positions the support lugs before welding, improving welding accuracy, ensuring welding consistency, and increasing welding efficiency and quality, making it suitable for mass production. The quadrilateral valve body is placed in the V-groove, and the switch is positioned away from the positioning plate, which can prevent the long can from rotating and limit the relative position of the support lugs and the switch, ensuring the switch is on the side away from the limiting support lugs.

[0023] like Figure 1-3 The illustrated welding fixture for a long tank includes a base plate 1, which is rectangular in shape. A baffle 2 and a support block 3 are connected to both ends of the short side of the base plate 1, respectively. The baffle 2 has a positioning hole 21, and the top surface of the support block 3 has a V-groove 31. A long tank 6 is mounted on the upper side of the base plate 1.

[0024] like Figure 4 The welding fixture for the long tank shown has a base plate 1 connected to the top surface of the base plate 1. The cross-section of the base plate 11 is arc-shaped. The base plate 11 and the positioning hole 21 are coaxially arranged. The long tank 6 is placed on the upper side of the base plate 11.

[0025] In this embodiment, the pressing device 5 includes a straight plate 51 arranged along the long side of the base plate 1. The straight plate 51 is connected to the base plate 1 via a column 52. The straight plate 51 extends upward toward the long tank 6. A sliding sleeve 53 is provided on the side of the straight plate 51 near the long tank 6. A hollow tube 54 is connected to the sliding sleeve 53. The hollow tube 54 is hollow and has a groove 541 on the side of the hollow tube 54 near the long tank 6. A notch is provided in the middle section of the groove 541. A pressure rod 55 is slidably connected inside. The pressure rod 55 extends from the lower end of the hollow tube 54. A pressure block 56 is connected to the lower end of the pressure rod 55. The pressure block 56 is rectangular, and its long side is arranged along the axis of the long tank 6. A pressure handle 57 is connected to the upper end of the pressure rod 55. A flexible rubber strip is provided on the bottom surface of the pressure block 56, and a positioning protrusion is provided on the pressure rod 55. The positioning protrusion is located in the groove 541. A spring is fitted on the lower side of the pressure rod 55. The upper end of the spring abuts against a ring integrally formed with the pressure rod 55, and the lower end of the spring abuts against a ring provided at the lower opening of the hollow tube 54. The spring pushes the pressure rod 55, so that the pressure handle 57 is at the upper end of the slide groove 541.

[0026] like Figure 5 The welding fixture for the long tank shown includes a positioning device 4 comprising two or more positioning plates 41, which are vertically positioned on the side of the long tank 6 away from the pressing device 5. A slide rail 42 is provided on the top surface of the base plate 1, perpendicular to the axis of the long tank 6. A push plate 43 is connected to the lower end of the positioning plate 41, forming an L-shape. The push plate 43 is slidably connected to the slide rail 42 via a slider 44. A transverse drive device 45 is connected to the end of the push plate 43 away from the positioning plate 41, pushing the push plate 43 along the slide rail 42.

[0027] like Figure 6 The welding fixture for the long tank shown includes a transverse drive device 45, which includes a connecting plate 441 connected to the base plate 1. The connecting plate 441 is connected to a bushing 442, and the bushing 442 is slidably connected to a drive rod 443. The drive rod 443 is driven to connect to a push plate 43. A handle 444 is hinged to the end of the drive rod 443 away from the push plate 43. The handle 444 is provided with a claw 4441. The claw 4441 and the handle 444 are integrally set at a right angle. The handle 444 is hinged to the drive rod 443 through the claw 4441. A connecting piece 445 is hinged at the connection between the claw 4441 and the handle 444. The connecting piece 445 is set parallel to the claw 4441. The end of the connecting piece 445 away from the handle 444 is hinged to the bushing 442.

[0028] like Figure 7The welding fixture for the long tank shown includes a valve 61 comprising a valve body 611, a switch 612, and a nozzle 613. The switch 612 is connected to the side wall of the valve body 611 and controls the opening and closing of the valve body 611. The nozzle 613 is connected to the side of the valve body 611 away from the long tank 6 and is connected to an air pipe. The valve body 611 has a quadrilateral cross-section, with a V-groove 31 correspondingly provided. The quadrilateral valve body 611 is placed within the V-groove 31, and the switch 612 is positioned away from the positioning plate 41. The long tank 6 is then pressed and fixed in place. The quadrilateral valve body 611 prevents the long tank 6 from rotating and limits the relative position of the support lug 7 and the switch 612, ensuring that the switch 612 is positioned away from the limiting support lug 7.

[0029] This utility model is used for welding lugs 7 to a long can 6. During welding, the long can 6 is placed on the support plate 11 on the upper side of the base plate 1. The long can 6 has a spherical end face 62, one end of which abuts against the baffle 2. The spherical end face 62 extends into the positioning hole 21. The valve body 611 is placed in the V-shaped groove 31 provided by the support block 3, and the switch 612 is placed on the side away from the positioning plate 41. The pressure handle 57 is turned, and the pressure handle 57 pushes the pressure rod 55 to slide down along the hollow tube 54. The positioning protrusion slides down along the slide groove 541. When the pressure block 56 squeezes the long can 6, the rubber strip on the pressure block 56 deforms, and the positioning protrusion is in the notch position provided in the middle section of the slide groove 541. The pressure handle 57 is rotated to turn the positioning protrusion into the notch provided in the middle section of the slide groove 541, pressing and fixing the long can 6. Pulling handle 444 causes it to rotate away from push plate 43. This rotation of handle 4441 causes claw 4441 to rotate, which in turn causes connecting piece 445 to rotate in the opposite direction. This, in turn, causes drive rod 443 to move towards push plate 43 until the hinge points of claw 4441 and connecting piece 445, drive rod 443, and connecting piece 445 and bushing 442 are aligned. At this point, claw 4441, connecting piece 445, and drive rod 443 are in a dead zone, thus positioning positioning plate 41 on one side of long tank 6. Lug 7 is then placed between positioning device 4 and long tank 6. Both sides of lug 7 abut against positioning plate 41 and long tank 6, providing radial positioning along long tank 6. Lug 7 is also positioned in the middle of positioning plate 41, providing axial positioning along long tank 6, and then welded.

[0030] After welding is complete, rotate the pressure handle 57 in the reverse direction. The positioning protrusion disengages from the notch in the middle section of the slide groove 541. The spring pushes the pressure rod 55 upward, and the pressure block 56 disengages from the long tank 6. Turn the handle 444 towards the push plate 43. The handle 444 drives the claw 4441 to rotate. The rotation of the claw 4441 drives the connecting piece 445 to rotate in the opposite direction, causing the drive rod 443 to move away from the push plate 43, thereby moving the positioning plate 41 away from the long tank 6. Finally, remove the welded long tank 6 and weld the next long tank 6.
