Description

Technical Field

[0001] The invention relates to the technical field of water boiler production, in particular to a spot welding fixture for an anti-shake water boiler. Background Art

[0002] A variety of tooling is required in the production process of water boilers, one of the most commonly used tooling is the spot welding fixture. When spot welding with the existing spot welding fixture, the pressure applied by the welding equipment is related to the operator's foot pedal depth. A shallow foot pedal depth will result in a small spot welding pressure and insufficient spot welding of the water boiler. On the contrary, a deep foot pedal depth will result in a large spot welding pressure and excessive spot welding of the water boiler. In addition, spot welding pressure fluctuations will make spot welding unstable, prone to poor welding or pad damage, resulting in low production efficiency of the water boiler. When the spot welding machine spot welds the steel cabinet of the water boiler, it needs to clamp and fix the steel cabinet with a fixture to prevent the steel cabinet from shaking during the spot welding process. However, the steel skin in the steel cabinet is elastic, so that when the fixture is fixing it, the steel skin cannot be quickly fixed due to its own elastic characteristics, which may still shake during the spot welding process, reducing the accuracy of spot welding. Stainless steel sheet cabinets have very high requirements on welding quality. Generally, laser welding machines are used to perform full-penetration welding on stainless steel sheet cabinets. To ensure the laser welding effect, it is required to first assemble five stainless steel sheets into a pentahedron for spot welding, so that full welding can be performed on the laser welding machine.

[0003] The existing anti-shake spot welding fixture for water boilers has structural design defects. The elasticity of the steel plate of the water boiler shell makes it easy to shake during spot welding. In addition, the water boiler is large in size and the position of the welding gun cannot be automatically adjusted for fast spot welding during welding. Summary of the invention

[0025] The present invention provides a spot welding fixture for an anti-shake water boiler, which has the following beneficial effects:

[0026] 1. The anti-shake water boiler uses a spot welding fixture. After the docking component fixes and limits the other four steel plates, the adjustment component drives the bending plate and the steel plate to approach the middle steel plate, so as to dock the middle steel plate with the other four steel plates. The screw slide is a structure composed of a drive motor, a threaded rod and a sliding cylinder. The drive motor drives the threaded rod to rotate, and the thread lift makes the sliding cylinder move close to the steel plate. The rapid welding mechanism moves to the internal position of the five steel plates for rapid multi-spot welding, which solves the problem that the elasticity of the steel plate of the water boiler shell makes it easy to shake during spot welding.

[0027] 2. The anti-sway water boiler uses a spot welding fixture. The sliding block slides on the surface of the sliding rod close to the negative pressure suction cup. There are multiple sliding rods. When the limit plate moves, the sliding rod firmly supports the movement of the limit plate. The steel plates on the four sides are driven by the bending plate to approach each other until the four steel plates are completely connected with the middle steel plate. The five steel plates are connected and limited before welding. The bending plate is in contact with the steel plate over a large area. The steel plate is supported and limited, which makes it difficult for the steel plate to bend and shake during welding, making the steel plate more stable and having a better welding effect.

[0028] 3. The anti-sway water boiler spot welding fixture uses a sliding seat to support the position adjustment component to extend to the inner side of the five steel plates. The motor drives the tooth surface roller to rotate, and the position adjustment component rotates under the drive of the tooth surface roller. The angle adjustment component performs multi-point welding on the butt edges of the five steel plates. When the support plate retracts, the angle adjustment component spot welds the remaining edges of the steel plates, which solves the problem that the water boiler is large in size and the position of the welding gun cannot be automatically adjusted for quick spot welding during welding.

[0029] 4. The spot welding fixture for the anti-sway water boiler, when the friction belt is driven to the inner side of the five steel plates, the welding gun welds the butt edges of the five steel plates. As the elastic shell rotates, the welding gun quickly performs multi-spot welding on the butt edges of the steel plates. The supporting shell reliably supports the rotation of the friction belt. The protective frame is arranged on the outer side of the friction belt. The protective frame supports the rotation of the friction belt. At the same time, the protective frame prevents the rotation of the friction belt from being disturbed by the outside world, so that the welding gun is more stable and less prone to shaking during welding.

[0030] 5. The anti-shake water boiler uses a spot welding fixture. The welding gun extends to the inner side of the five steel plates for spot welding. The oppositely arranged arc cylinders and the connection method of the sphere can control the rotation angle of the welding gun. The rotating table drives the welding gun to rotate, thereby adjusting the angle between the output end of the welding gun and the butt edge of the steel plate. At the same time, the five steel plates are clamped, and the butt edges of the five steel plates can be quickly multi-spot welded by the welding gun, thereby effectively improving the efficiency of water boiler manufacturing.

The bending plate 55 is arranged on the side of the adjustment component 51 away from the fixing seat 2. The bending plate 55 is used to slide and limit the steel plates. The docking component 56 is fixedly installed on the surface of the bending plate 55. The docking component 56 is used to fix and limit the sliding steel plates.

[0047] The anti-sway mechanism 5 further includes a limit plate 53 , which is fixedly mounted on the surface of the adjustment component 51 . There are four limit plates 53 , and an extension end 54 is disposed on the surface of the limit plate 53 below the adjustment component 51 .

[0048] When in use, the fixed seat 2 firmly limits the adjustment component 51, and the negative pressure suction cup 52 adsorbs the middle position of one steel plate, which is called the middle steel plate. The water boiler shell requires five steel plates, and the remaining steel plates slide into the inner side of the bending plate 55. The limiting plate 53 firmly supports the bending plate 55. When the side steel plate slides downward, the extension end 54 limits the bottom of the steel plate to prevent it from falling. After the docking component 56 fixes the remaining four steel plates, the adjusting component 51 drives the bending plate 55 and the steel plate to approach the middle steel plate, thereby docking the middle steel plate with the remaining four steel plates. The screw slide 3 is a structure composed of a driving motor, a threaded rod and a sliding cylinder. The driving motor drives the threaded rod to rotate, and the thread lift causes the sliding cylinder to move close to the steel plate. The quick welding mechanism 6 moves to the internal position of the five steel plates for quick multi-spot welding, which solves the problem that the elasticity of the steel plate of the water boiler shell makes it easy to shake during spot welding.

[0049] Second embodiment: Figure 3 , Figure 4 , Figure 5 As shown, the adjustment component 51 includes a center platform 511, the surface of the center platform 511 is fixedly connected to the middle position of the surface of the fixed seat 2, the surface of the center platform 511 is fixedly connected with a slide bar 512, the surface of the center platform 511 near the slide bar 512 is fixedly connected with an electric cylinder 513, the rotating shaft at the output end of the electric cylinder 513 is fixedly connected to the surface of the limit plate 53, the surface of the limit plate 53 is fixedly connected with a sliding block 514, the docking component 56 includes a gate hoist 561, the surface of the gate hoist 561 is fixedly connected to the surface of the bending plate 55, the screw rod at the output end of the gate hoist 561 extends to the inner side of the bending plate 55, the docking component 56 also includes an adhesive sheet 562, the bottom of the adhesive sheet 562 is fixedly connected to the middle position of the steel plate surface, and the surface of the adhesive sheet 562 is fixedly connected to the limit cylinder 563;

[0050] The docking assembly 56 further includes a limiting slide 565 , which is fixedly mounted on the surface of the limiting cylinder 563 at a position away from the screw rod. An internal thread groove 564 is formed on the inner side surface of the limiting cylinder 563 .

[0051] When in use, after the middle steel plate is limited by the negative pressure suction cup 52, the steel plates on the other four sides slide into the inner side of the bending plate 55, and the adhesive sheet 562 is fixed in the middle position of the steel plate surface. When the steel plate slides into the bending plate 55, the inner side of the bending plate 55 and the surface of the limiting slide plate 565 slide against each other, so that one side of the steel plate is close to the inner side of the bending plate 55. The four limiting plates 53 support the four steel plates respectively, and the electric cylinder 513 drives the limiting plate 53 to move close to the middle platform 511, and the sliding block 51 The slide bar 512 slides on the surface of the slide bar 512 and approaches the negative pressure suction cup 52. There are multiple slide bars 512. When the limit plate 53 moves, the slide bar 512 firmly supports the movement of the limit plate 53. The steel plates at the four sides are driven by the bending plate 55 to approach each other until the four side steel plates are completely butted with the middle steel plate. The five side steel plates are butted and limited before welding. The bending plate 55 contacts the steel plate with a large area. The steel plate is supported and limited, so that the steel plate is not easy to bend and shake during welding, so that the steel plate is stable and the welding effect is better.

[0052] The third embodiment: Figure 3 , Figure 6 As shown, the anti-sway mechanism 5 includes an adjustment component 51, which is fixedly installed at the middle position of the surface of the fixing seat 2, and the adjustment component 51 is used to adjust the distance between the steel plates so that the steel plates are butted against each other;

The surface of the position adjustment component 65 is fixedly connected to an angle adjustment component 66, and the surface of the support plate 61 is fixedly connected to a protective frame 64.

[0055] When in use, the area of ​​the five steel plates of the water boiler is large, which makes it difficult to clamp and limit during welding. After every two steel plates are butt-welded, the third steel plate is difficult to butt. The device uses the bending plate 55 and the butt assembly 56 to limit the four steel plates. The negative pressure suction cup 52 determines the position of the middle steel plate. The adjustment assembly 51 controls the bending plate 55 and the four steel plates to approach the middle steel plate, thereby realizing the rapid butt joint of the five steel plates.

The position adjustment assembly 65 rotates under the drive of the tooth surface roller 63. The angle adjustment assembly 66 performs multi-spot welding on the butt joint edges of the five steel plates.

[0059] When in use, the inner side surface of the friction belt 652 meshes with the surface of the toothed roller 63, the support shell 651 supports the inner side surface of the elastic shell 653, the rotation of the toothed roller 63 causes the friction belt 652 to rotate, and the elastic shell 653 slides on the surface of the support shell 651. When the elastic shell 653 rotates, the roller 655 rolls on the surface of the support shell 651. The thickness of the fixed plate 654 is small and will not interfere with the rotation of the elastic shell 653. The rigidity of the fixed plate 654 provides a stable support for the rotating table 661. When the friction belt 652 When being driven to the inner side of the five steel plates, the welding gun 663 welds the butt edges of the five steel plates. As the elastic shell 653 rotates, the welding gun 663 quickly performs multi-point welding on the butt edges of the steel plates.
