Description

[0002] Sheet metal processing is a comprehensive cold processing technology for thin metal plates, including shearing, punching, cutting, compounding, folding, welding, splicing, and forming. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal processing are called sheet metal parts. Metal welding refers to the welding process in which the workpiece and solder melt to form a molten area. After the molten pool cools and solidifies, a connection between the materials is formed. When welding two stamped sheet metal substrates, the operation steps generally include substrate processing, assembly and fixation, welding and post-weld processing. In the assembly and fixation process, the welding method of the stamped sheet metal substrate generally includes horizontal butt welding and inclined angle welding. At this time, the stamped sheet metal parts need to be horizontally aligned or tilted, and the stability of the substrate before welding is achieved with the help of positioning methods such as spot welding and clamps, so as to avoid displacement during the subsequent welding process.

Although it can effectively achieve the positioning processing before welding, its operation is relatively complicated and the positioning effect is obviously insufficient, especially for the inclined angle welding of the stamped sheet metal substrate.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] Example 1: See also Figure 1-9 The present invention provides a stamping sheet metal welding device, comprising a workbench 1 and a welding frame 2, and further comprising a placement rod 3, wherein the placement rod 3 is provided in plurality and fixed to the side walls of the workbench 1 at equal intervals, and a pushing mechanism 4 for positioning the stamping sheet metal is provided between the plurality of placement rods 3 on the same side, and a pressing and positioning mechanism 5 is provided above one of the pushing mechanisms 4; It should be noted that the welding frame 2 is provided with a gas shielded welding device for welding stamped sheet metal parts. The control system realizes the moving trajectory of the welding gun, thereby performing mobile welding on the horizontal butt joints or inclined angle joints of two stamped sheet metal parts. This is a common welding device in the field, and this case aims to describe in detail the assembly and fixing method of the horizontal butt welding or inclined angle welding of the stamped sheet metal parts. Therefore, how to weld the stamped sheet metal parts is not described in detail. The rotating frame 6 is away from the pressing and positioning mechanism 5 and is rotatably mounted on the middle inner wall of the workbench 1. The interior of the rotating frame 6 is provided with an adsorption positioning mechanism 7 that cooperates with another pushing mechanism 4; The receiving roller 8 is located below the welding frame 2 and is adjacent to the rotating frame 6. A rotation adjustment mechanism 9 is provided on the outside of the workbench 1; It should be noted that, by setting the pushing mechanisms on both sides, the stamped sheet metal substrates to be welded can be pushed to the front end of the welding frame 2 respectively. At this time, the stamped sheet metal substrate on one side is positioned by the adsorption positioning mechanism 7, and the stamped sheet metal substrate on the other side is pressed and positioned by the pressing positioning mechanism 5, and is pushed again by the pushing mechanism 4, thereby realizing the horizontal docking of the two stamped sheet metal substrates, completing the positioning of the horizontal butt welding of the two stamped sheet metal substrates, which is simple to operate, highly automated, and has a significantly better positioning effect than spot welding or fixture positioning. When performing inclined angle welding on two stamped sheet metal substrates, when one of the stamped sheet metal substrates is pushed to the rotating frame 6 under the welding frame 2 by the pushing mechanism 4, it is adsorbed and positioned by the adsorption positioning component. At the same time, the other pushing mechanism 4 pushes the other stamped sheet metal substrate to the top of the receiving roller 8, and there is a certain distance between it and the stamped sheet metal substrate to be rotated. Then, the rotating frame 6 is rotated by the rotation adjustment mechanism 9 to form an inclined placement of the stamped sheet metal substrate. Finally, the pressing and positioning mechanism 5 is used to fine-tune the stamped sheet metal substrate that is pressed by the pushing mechanism 4 again, thereby completing the inclined docking of the stamped sheet metal substrate that is rotated and adsorbed and positioned and the stamped sheet metal substrate that is horizontally pushed and pressed and positioned, and completing the precise positioning of the two stamped sheet metal substrates during the inclined angle welding process.

[0022] Further as Figure 1 、 Figure 3 and Figure 5 As shown, it is worth noting that the pushing mechanism 4 includes a sliding rod 41, which is arranged on the bottom surface of the multiple placement rods 3. A pushing frame 42 is fixed to the outer surface of the sliding rod 41, and two pushing cylinders 43 are respectively fixed to the two ends of the sliding rod 41 under the workbench 1. Rollers 44, multiple rollers 44 are provided and are equidistantly installed on the top surface of the pushing frame 42, and the pushing frame 42 is integrally formed with multiple parallel arc-shaped protrusions 45 at one end close to the welding frame 2; It should be noted that the stamped sheet metal substrate to be welded is placed on the edge of the workbench 1 and is rolled and transported by the roller 44, so that it can be pushed to the arc-shaped protrusion 45 above the pushing rack 42, thereby forming a preliminary placement of the stamped sheet metal substrate. Subsequently, the sliding rod 41 can be driven by the pushing cylinder to move toward the welding rack 2, so that the stamped sheet metal substrate can be moved.

[0023] Further as Figure 1 and Figure 5 As shown, it is worth noting that the top horizontal section of the roller 44 and the top horizontal section of the arc-shaped protrusion 45 are located at the same horizontal plane and are higher than the top surface of the placement rod 3, and the arc-shaped protrusion 45 and the rotating frame 6 are plug-connected; It should be noted that the plurality of rollers 44 and the plurality of arc-shaped protrusions 45 make line contact with the stamped sheet metal substrate, so that the stamped sheet metal substrate can be stably placed above the pushing rack 42, thereby facilitating the pushing and positioning of the pushing rack 42 and the stamped sheet metal substrate by the pushing cylinder 43; The arc-shaped protrusion 45 is plugged into the rotating frame 6 so that when the stamped sheet metal substrate is moved along with the pushing frame 42, the arc-shaped protrusion 45 does not interfere with the rotating frame 6, thereby facilitating the adsorption and positioning mechanism 7 to adsorb and position the pushed stamped sheet metal substrate.

[0024] Further as Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 9 As shown, it is worth mentioning that the pressing and positioning mechanism 5 includes two fixing frames 51, which are fixed to both ends of the top surface of the pushing frame 42. The top surfaces of the two fixing frames 51 are slidably connected to the moving plates 52, and a travel member 53 for moving the moving plate 52 is provided above one of the fixing frames 51. A plurality of clamping rods 54 are provided and slide equidistantly through the top surface of the movable plate 52. A mounting frame 55 is fixed to the bottom ends of the clamping rods 54. A clamping spring 56 is provided on the outer surface of the clamping rod 54 and is fixed to the opposite surfaces of the mounting frame 55 and the movable plate 52. A clamping roller 57 is rotatably connected to the inner wall of the mounting frame 55. An arc-shaped guide groove 58 is provided in the middle of the fixed frame 51 to cooperate with the rotating shafts at both ends of the clamping roller 57. The travel member 53 includes a fixed rack rod 531 , which is fixed to the top surface of the fixed frame 51 , and a travel gear 532 is meshed and connected to the top of the fixed rack rod 531 ; A travel motor 533 is mounted on the top surface of the movable plate 52 , and an output end of the travel motor 533 is coaxially connected to the travel gear 532 via a coupling; It should be noted that the stamped sheet metal substrate is placed on the roller 44 and pushed to the arc-shaped protrusion 45, so that the part to be welded of the stamped sheet metal substrate is away from the end of the arc-shaped protrusion 45. At this time, the travel motor 533 is driven and the travel gear 532 is engaged with the fixed rack rod 531, so that the movable plate 52 is moved on the fixed frame 51. The clamping roller 57 is formed by the clamping rod 54 and the clamping spring 56 to adjust the height on the movable plate 52, that is, the clamping roller 57 is driven to move in the arc-shaped guide groove 58. At this time, the travel direction of the travel motor 533 is controlled according to the thickness of the stamped sheet metal substrate until the clamping roller 57 contacts and presses the top surface of the stamped sheet metal substrate, thereby completing the clamping and positioning of the stamped sheet metal substrate.

[0025] Further as Figure 2 、 Figure 5 and Figure 9As shown, it is worth mentioning that the outer surface of the pressing roller 57 is provided with an anti-slip groove, and the periphery of the pressing roller 57 is provided with three pressing plates 10 fixed to the outer surface of the mounting frame 55. The setting of the anti-slip groove is used to improve the pressing effect of the pressing roller 57 on the top surface of the stamped sheet metal substrate to a certain extent. The three pressing plates 10 are arranged in an isosceles triangle, which cooperates with the pressing roller 57 to press the stamped sheet metal substrate left and right, further increasing the size of the pressing and positioning area, thereby further improving the pressing and positioning effect on the stamped sheet metal substrate.

[0026] Further as Figure 1 、 Figure 3 、 Figure 5 and Figure 8 As shown, it is worth noting that the adsorption positioning mechanism 7 includes a positioning frame 71, which is fixed to the outer surface of the bottom of the rotating frame 6. The interior of the rotating frame 6 is provided with an adsorption frame 72 connected to the positioning frame 71, and the bottom of the positioning frame 71 is connected to a negative pressure pipe 73. The barrier filter 74 is elliptical and is embedded in the positioning frame 71; It should be noted that the other end of the negative pressure tube 73 is connected to a vacuum generator, and the negative pressure force is provided through the adsorption frame 72 by connecting the left and right sides of the negative pressure tube 73; The barrier filter 74 is provided to block impurities and can also absorb and block the metal smoke during welding of the stamped sheet metal substrate. It should be noted that when the stamped sheet metal substrate is pushed to the top of the rotating frame 6 by the pushing mechanism 4, a negative pressure force is provided to the positioning frame 71 and the adsorption frame 72 by the vacuum generator, so that the stamped sheet metal substrate is adsorbed and positioned above the rotating frame 6 and the adsorption frame 72 by the negative pressure, thereby forming an adsorption and positioning process for the stamped sheet metal substrate; When the stamped sheet metal substrate needs to be rotated, the rotating frame 6 is driven to rotate by the rotation adjustment mechanism 9, so that the stamped sheet metal substrate adsorbed on the adsorption frame 72 can be adjusted in angle along with the rotating frame 6, and the stamped sheet metal substrate is pushed and aligned by another pushing mechanism 4, thereby forming the docking and positioning treatment of the two stamped sheet metal substrates before the inclined angle welding.

[0027] Further as Figure 1 、 Figure 3 and Figure 5 As shown, it is worth noting that the rotation adjustment mechanism 9 includes a transmission gear 91, and two rotation gears 99 are provided and are coaxially fixed with the two end shafts of the rotating frame 6; The pulling rack rod 92 is provided with two and is respectively engaged with the two transmission gears 91 , and the outer wall of the workbench 1 is installed with a pulling cylinder 93 fixed with the pulling rack rod 92 .

[0028] It should be noted that when the rotating frame 6 needs to be rotated, the rack rod 92 is first pulled away from the rotating frame 6 by pulling the cylinder 93, and the meshing transmission effect of the rack rod 92 and the transmission gear 91 can be used to rotate the rotating frame 6 toward the welding frame 2, so that the stamped sheet metal substrate is rotated and adsorbed and positioned.

[0029] This embodiment has the following working process: when performing horizontal butt welding on two stamped sheet metal substrates, first, the two stamped sheet metal substrates to be welded are placed on the pushing rack 42, and are pushed to the outside of the arc-shaped protrusion 45 of the pushing rack 42 by the action of the roller 44, thereby forming the initial placement of the two stamped sheet metal substrates, and then the stamped sheet metal substrate close to the rotating rack 6 is pushed to the top of the rotating rack 6 by the pushing mechanism 4, and at the same time, it is subjected to negative pressure adsorption positioning treatment by the adsorption positioning mechanism 7, and the other stamped sheet metal substrate is then driven by the travel motor 533 in the pressing and positioning mechanism 5, so that the pressing roller 57 and the pressing plate 10 are pressed against the surface of the stamped sheet metal substrate, forming multiple pressing treatments on the stamped sheet metal substrate, and finally, the stamped sheet metal substrate that has been pressed is pushed to the stamped sheet metal substrate that has been completed by negative pressure adsorption positioning by the pushing mechanism 4, thereby completing the horizontal docking positioning treatment of the two stamped sheet metal substrates; When performing angled fillet welding on two stamped sheet metal substrates, first place the two stamped sheet metal substrates to be welded on the pushing rack 42, and push them to the outside of the arc-shaped protrusion 45 of the pushing rack 42 through the action of the roller 44, thereby forming a preliminary placement of the two stamped sheet metal substrates, and then push the stamped sheet metal substrate close to the rotating rack 6 to the top of the rotating rack 6 through the pushing mechanism 4, and at the same time, perform negative pressure adsorption positioning treatment on it through the adsorption positioning mechanism 7, and then drive the rotating adjustment mechanism 9 to make the stamped sheet metal substrate that has been adsorbed be positioned. The sheet metal substrate is tilted and rotated along with the rotating frame 6 to complete the tilt adsorption positioning processing of the stamped sheet metal substrate. At this time, the other stamped sheet metal substrate is driven by the travel motor 533 in the clamping and positioning mechanism 5, so that the clamping roller 57 and the clamping plate 10 are pressed against the surface of the stamped sheet metal substrate, forming multiple clamping processing of the stamped sheet metal substrate. Finally, the stamped sheet metal substrate that has been clamped is pushed to the stamped sheet metal substrate that has been positioned by negative pressure adsorption through the pushing mechanism 4, thereby completing the tilted corner welding positioning processing of the two stamped sheet metal substrates.

[0030] Example 2: On the basis of Example 1, according to Figure 1 、 Figure 4 、 Figure 5 and Figure 8 As shown, it is worth mentioning that the rotation adjustment mechanism 9 also includes a rotating rod 94, which is provided with two rotating rods 94 and is rotatably mounted on the inner walls of both ends of the workbench 1. A sliding groove 95 is provided on the outer surface of the rotating rod 94. The rotating shaft of the receiving roller 8 passes through the sliding groove 95 and is sleeved with a fixed block 96. A guide sleeve 97 fixed to the outer surface of the rotating rod 94 is provided below the fixed block 96. A vertical rod 98 slides through the inner wall of the guide sleeve 97. The top of the vertical rod 98 is fixed to the bottom surface of the fixed block 96. A rotating gear 99 is coaxially fixed to the periphery of the rotating rod 94. The rotating gear 99 is meshed and connected with the pulling rack rod 92. The pressing spring 910 is provided on the outer surface of the vertical rod 98 and is fixed to the opposite surfaces of the guide sleeve 97 and the fixing block 96 respectively.

[0031] On the basis of the first embodiment, this embodiment further has the following working process: when performing inclined fillet welding on two stamped sheet metal substrates, when the rotating frame 6 rotates, the stamped sheet metal substrate away from the rotating frame 6 is pushed to the top of the receiving roller 8 by the pushing mechanism 4, thereby supporting the edge of the stamped sheet metal substrate; When the rotating frame 6 rotates, the rotating rod 94 also rotates synchronously, so that the receiving roller 8 moves toward the bottom of the guide sleeve 97 through the fixed block 96 and the vertical rod 98, and drives the clamping spring 910 to be compressed, so that the receiving roller 8 can be clamped against the edge of the stamped sheet metal substrate, further ensuring the edge support effect of the stamped sheet metal substrate.

[0032] In summary, in combination with the two embodiments, it can be seen that: through the mutual cooperation of the pushing mechanism 4, the adsorption positioning mechanism 7 and the pressing positioning mechanism 5, the two stamped sheet metal substrates can be automatically moved and docked on the workbench 1, and the two stamped sheet metal substrates are respectively pressed and positioned and positioned by negative pressure adsorption, which effectively ensures the positioning accuracy of the two stamped sheet metal substrates during horizontal butt welding. Compared with spot welding or fixture positioning, its operation is simpler and more automated, and its positioning effect is significantly improved. By setting the rotating adjustment mechanism 9 and according to the mutual cooperation of the pushing mechanism, the adsorption positioning mechanism 7 and the pressing positioning mechanism 5, the two stamped sheet metal substrates can be adjusted for inclined angle welding under the conditions of pressing positioning and negative pressure adsorption positioning respectively, thereby further improving the diversity of the welding methods when the stamped sheet metal substrates are welded.

[0033] The travel motor 533, the pushing cylinder and the pulling cylinder 93 can all be purchased from the market and equipped with separate power supplies. They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
