Description

Technical Field

[0001] The present invention relates to the technical field of automotive hardware welding, and specifically to a welding device for processing automotive hardware. Background Art

[0002] Automotive hardware is the various units that make up the overall automotive parts processing and the products serving automotive parts processing. When processing automotive hardware, its components need to be welded.

[0003] Among them, some automotive components will be directly exposed to the public view. Therefore, while ensuring the welding strength, the aesthetics of the welding also needs to be guaranteed. Therefore, the fish-scale welding of argon arc welding is mostly used. However, this type of welding requires long-term practice by workers with both hands to meet the welding standards, which makes it difficult to use assembly line production for the above welding method and affects the welding efficiency of the equipment. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a welding device for processing automotive hardware, including a housing. A transfer pipe is connected through the top of the housing, and one end of the transfer pipe away from the housing is connected through a welding gun. A handle is fixedly connected to the top of the housing. The welding device further includes: A fixing mechanism fixedly connected to the side wall of the housing for driving the welding gun to swing and increasing the welding surface; A pressing mechanism fixedly connected to both sides of the housing for providing welding wire for the fixing mechanism; A pressure mechanism fixedly connected to the outer wall of the fixing mechanism for restricting the sliding of the welding wire; Two rollers are rotatably connected to both sides of the housing; Among them, before use, the welding wire is first placed inside the pressing mechanism, and then the housing is driven to slide along the outer wall of the welding seam through the handle, so that the welding gun welds the welding seam.

[0005] Preferably, the fixing mechanism includes: A driving component fixedly connected to the side wall of the housing through a support member; The support member includes a first fixing plate fixedly connected to the side wall of the housing, and a first rotating rod is rotatably connected to the inner wall of the first fixing plate; A feeding component fixedly connected to the side wall of the first fixing plate through a feeding member; The feeding member includes a placing pipe connected through the side wall of the first fixing plate. A first push rod is rotatably connected to the outer wall of the roller. A second fixing frame is fixedly connected to the side wall of the first fixing plate, and a sliding toothed rod is slidably connected to the outer wall of the second fixing frame; Among them, the roller drives the sliding toothed rod to slide up and down along the outer wall of the second fixing frame through the first push rod.

[0006] Preferably, the pressing mechanism includes: An auxiliary component, which is slidably connected to the outer wall of the placement tube through a sliding member; The sliding member includes a sliding ring slidably connected to the outer wall of the placement tube; A buckle component, which is fixedly connected to the side wall of the sliding ring through a pushing member; The pushing member includes a pushing frame fixedly connected to the side wall of the sliding ring, and the outer wall of the pushing frame is slidably connected to the inner wall of the first fixing plate; Wherein, the roller slides along the outer wall of the placement tube through the fixing mechanism and drives the buckle component to move synchronously.

[0007] Preferably, the pressure mechanism includes: A pressing component, which is fixedly connected to the outer wall of the placement tube through a limiting member; The limiting member includes a fixing block fixedly connected to the outer wall of the placement tube, and a sliding rod is slidably connected to the inner wall of the fixing block; A pressure component, which is fixedly connected to the top of the fixing block through a driving member; The driving member includes a second fixing plate fixedly connected to the top of the fixing block; Wherein, when the sliding ring drives the buckle component to slide through the pushing frame, the buckle component drives the sliding rod to slide up and down along the inner wall of the fixing block through the pressure component.

[0008] Preferably, the driving component includes a first gear fixedly connected to the outer wall of the rotating rod, and a first fixing frame is fixedly connected to the end of the rotating rod away from the first gear; Wherein, when the sliding rack slides up and down, the first gear meshing with the sliding rack will rotate correspondingly, and since the up and down amplitude of the sliding rack is small, the rotation angle of the first gear and the first fixing frame is small.

[0009] Preferably, the feeding component includes a second push rod rotatably connected to the outer wall of the roller, a pulling rod is rotatably connected to the end of the second push rod away from the roller, and the end of the pulling rod away from the second push rod is fixedly connected to the outer wall of the sliding ring; Wherein, when the roller rotates, it will force the second push rod and the pulling rod to drive the sliding ring to slide up and down along the outer wall of the placement tube.

[0010] Preferably, the auxiliary component includes an arc plate fixedly connected to the inner wall of the sliding ring, the outer wall of the arc plate is slidably connected to the inner wall of the placement tube, and a spring piece is fixedly connected to the inner wall of the arc plate; Among them, when the sliding ring slides along the outer wall of the placement tube, when the sliding ring drives the spring piece to slide upward, due to the influence of the inclination angle of the spring piece, the end of the spring piece will slide along the outer wall of the welding wire at this time. When the sliding ring drives the spring piece to slide downward, due to the influence of the spring piece angle, the spring piece will exert pressure on the welding wire at this time, forcing the welding wire to slide downward.

[0011] Preferably, the buckle assembly includes a pressure ring fixedly connected to the end of the push frame away from the sliding ring, and an L-shaped tooth bar is fixedly connected to the outer wall of the pressure ring; Among them, the sliding ring drives the L-shaped tooth bar to move synchronously through the push frame.

[0012] Preferably, the pressure application assembly includes a second tooth bar fixedly connected to the outer wall of the sliding rod, a sliding tooth block is slidably connected to the inner wall of the second tooth bar, and a first spring is fixedly connected to the side wall of the sliding tooth block; Among them, under the continuous rotation of the pressure assembly, since the sliding tooth block can slide, the sliding tooth block and the first spring effectively relieve the excessive pressure of the pressure assembly on the sliding rod.

[0013] Preferably, the pressure assembly includes a second gear rotatably connected to the side wall of the second fixing plate, and a third gear is fixedly connected to the side wall of the second gear; Among them, the L-shaped tooth bar meshes with the side wall of the second gear, and the third gear meshes with the outer wall of the second tooth bar.

[0014] The present invention has the following beneficial effects: (1) Aiming at the problem of the large operation difficulty of "fish scale pattern" in the present invention, when welding is required, the staff drives the equipment to slide along the outer wall of the gap. During this process, the two rollers will rotate. The left roller will drive the sliding tooth bar to slide up and down along the outer wall of the second fixing frame through the first push rod. The sliding tooth bar will drive the first gear to rotate clockwise or counterclockwise. The first gear drives the first fixing frame to rotate in the same direction through the rotating rod. Finally, the first fixing frame will drive the welding gun to swing left and right. During this process, the welding gun heats the welding wire inside the placement tube, making the wire melt. The metal solution covers the outer wall of the gap. The left and right swinging welding gun will drive the metal melt to move synchronously. Finally, "fish scale pattern" is formed at the welding part on the outer wall of the gap. Through the application of the above components, the welding difficulty of "fish scale pattern" is effectively reduced, and the welding efficiency is improved.

[0015] (2)The present invention utilizes the characteristic that the above rollers rotate. An inlet component is arranged inside the device. When the right roller rotates, the roller drives the pulling rod and the sliding ring to slide up and down along the outer wall of the placement tube through the second push rod. When the sliding ring slides along the outer wall of the placement tube and drives the spring piece to slide upward, due to the influence of the inclination angle of the spring piece, at this time, the end of the spring piece will slide along the outer wall of the welding wire. When the sliding ring drives the spring piece to slide downward, due to the influence of the spring piece angle, at this time, the spring piece will exert pressure on the welding wire, forcing the welding wire to slide downward. Through the application of the above components, the stable feeding of the molten metal is ensured, and the thickness of the "fish scale pattern" is made uniform.

[0016] (3)The present invention utilizes the characteristic that the above sliding ring slides up and down. The sliding ring drives the L-shaped toothed rod to move synchronously through the push frame. The L-shaped toothed rod will drive the second gear to rotate. The second gear drives the second toothed rod to slide up and down through the third gear. And in this process, when the sliding rod reaches the top or bottom, at this time, the third gear will rotate, and the rotating force will be applied to the outer wall of the sliding tooth block, causing the sliding tooth block to squeeze the first spring. After the external pressure disappears, the first spring pushes the sliding tooth block to reset. Through the application of the above components, when the sliding ring moves upward, at this time, the sliding rod will slide downward and squeeze the welding wire, preventing the welding wire from falling downward due to vibration and causing the accumulation of molten metal.

[0017] (4)The present invention utilizes the characteristic that the sliding rod slides up and down along the inner wall of the fixed block. When the sliding ring slides downward, the sliding rod moves away from the outer wall of the welding wire, enabling the spring piece to drive the welding wire to move downward along the inner wall of the sliding ring, avoiding the obstruction of the bottom sliding rod, which may cause deformation of the welding wire and ultimately result in protrusion or depression in the width of the "fish scale pattern", affecting the integrity of the "fish scale pattern".

On the basis of Embodiment 1, the driving component 11 includes a first gear 114 fixedly connected to the outer wall of the rotating rod 112, and a first fixing frame 113 is fixedly connected to the end of the rotating rod 112 away from the first gear 114; When welding is required, the staff drives the device to slide along the outer wall of the gap. During this process, the two rollers 121 will rotate.

[0027] The feeding component 12 includes a second push - rod 125 rotatably connected to the outer wall of the roller 121. One end of the second push - rod 125 away from the roller 121 is rotatably connected to a pulling rod 126, and one end of the pulling rod 126 away from the second push - rod 125 is fixedly connected to the outer wall of the sliding ring 211; Among them, when the roller 121 rotates, it will force the second push rod 125 and the pulling rod 126 to drive the sliding ring 211 to slide up and down along the outer wall of the placement tube 127.

[0028] The auxiliary component 21 includes an arc-shaped plate 212 fixedly connected to the inner wall of the sliding ring 211. The outer wall of the arc-shaped plate 212 is slidably connected to the inner wall of the placement tube 127, and a spring piece 213 is fixedly connected to the inner wall of the arc-shaped plate 212; Among them, when the sliding ring 211 slides along the outer wall of the placement tube 127, when the sliding ring 211 drives the spring piece 213 to slide upward, due to the influence of the inclination angle of the spring piece 213, at this time, the end of the spring piece 213 will slide along the outer wall of the welding wire.

[0030] The pressure application component 31 includes a second tooth bar 313 fixedly connected to the outer wall of the sliding rod 312. A sliding tooth block 314 is slidably connected to the inner wall of the second tooth bar 313, and a first spring 315 is fixedly connected to the side wall of the sliding tooth block 314; Utilizing the characteristics of the up and down sliding of the above-mentioned sliding ring 211, the sliding ring 211 drives the L-shaped tooth bar 223 to move synchronously through the push frame 221. The L-shaped tooth bar 223 will drive the second gear 322 to rotate. The second gear 322 drives the second tooth bar 313 to slide up and down through the third gear 323. And in this process, when the sliding rod 312 reaches the top or bottom, at this time, the third gear 323 will rotate, and the rotating force will be applied to the outer wall of the sliding tooth block 314 at this time, so that the sliding tooth block 314 squeezes the first spring 315, and after the external pressure disappears, the first spring 315 pushes the sliding tooth block 314 to reset. Through the application of the above components, when the sliding ring 211 moves upward, at this time, the sliding rod 312 will slide downward and squeeze the welding wire to prevent the welding wire from falling downward due to vibration; Among them, the sliding tooth block 314 and the first spring 315, under the continuous rotation of the pressure component 32, since the sliding tooth block 314 can slide, effectively relieve the excess pressure of the pressure component 32 on the sliding rod 312.

[0032] A specific application of this embodiment is as follows: Before using the present invention, after the plates are butted, the staff holds the grip 16 by hand, places the gap at the center of the device, then places the welding wire into the inner wall of the placement tube 127, and turns on the power supply of the housing 13; When welding is required, the staff drives the device to slide along the outer wall of the gap. During this process, the two rollers 121 will rotate. The left roller 121 will drive the sliding tooth rod 124 to slide up and down along the outer wall of the second fixed frame 123 through the first push rod 122. The sliding tooth rod 124 will drive the first gear 114 to rotate clockwise or counterclockwise. The first gear 114 drives the first fixed frame 113 to rotate in the same direction through the rotating rod 112. Finally, the first fixed frame 113 will drive the welding gun 15 to swing left and right. During this process, the welding gun 15 heats the welding wire inside the placement tube 127, making the wire melt, and the molten metal covers the outer wall of the gap. The swinging welding gun 15 will drive the molten metal to move synchronously. Finally, "fish scale patterns" are formed at the welding joints on the outer wall of the gap. Through the application of the above components, the welding difficulty of the "fish scale pattern" is effectively reduced, and the welding efficiency is improved.

[0033] Utilizing the rotation characteristics of the above-mentioned roller 121, a feeding assembly 12 is provided inside the device. When the right roller 121 rotates, the roller 121 drives the pulling rod 126 and the sliding ring 211 to slide up and down along the outer wall of the placement tube 127 through the second push rod 125. When the sliding ring 211 slides along the outer wall of the placement tube 127, when the sliding ring 211 drives the spring piece 213 to slide upward, due to the influence of the inclination angle of the spring piece 213, the end of the spring piece 213 will slide along the outer wall of the welding wire at this time. When the sliding ring 211 drives the spring piece 213 to slide downward, due to the angle influence of the spring piece 213, the spring piece 213 will exert pressure on the welding wire at this time, forcing the welding wire to slide downward. Through the application of the above components, the stable feeding of the molten metal is ensured, and the thickness of the "fish scale pattern" is uniform.

[0034] Taking advantage of the characteristics of the above-mentioned sliding ring 211 sliding up and down, the sliding ring 211 drives the L-shaped rack 223 to move synchronously through the push frame 221. The L-shaped rack 223 drives the second gear 322 to rotate. The second gear 322 drives the second rack 313 to slide up and down through the third gear 323. During this process, when the sliding rod 312 reaches the top or bottom, the third gear 323 will rotate at this time, and the rotating force will be applied to the outer wall of the sliding tooth block 314, causing the sliding tooth block 314 to squeeze the first spring 315. After the external pressure disappears, the first spring 315 pushes the sliding tooth block 314 to reset. Through the application of the above components, when the sliding ring 211 moves upward, the sliding rod 312 will slide downward at this time and squeeze the welding wire to prevent the welding wire from falling downward due to vibration. When the sliding ring 211 slides downward, the sliding rod 312 moves away from the outer wall of the welding wire, enabling the spring piece 213 to drive the welding wire to move downward along the inner wall of the sliding ring 211, avoiding the obstruction of the bottom sliding rod 312, resulting in deformation of the welding wire, and ultimately causing protrusion or depression in the width of the "fish scale pattern", affecting the appearance.
