Description

Technical Field

[0002] When welding plates and strips, the welding slag produced during the welding process is easy to adhere to the backing plate, affecting the flatness of the backing plate. Subsequent clamping may cause local bulges at the welding position, thus affecting the overall flatness. In addition, it is easy to scratch the welded parts when they are sent out after welding. In addition, when the current welding structure needs to achieve two-dimensional welds such as wavy or oblique welds, there is an instability problem when the welding gun swings back and forth, resulting in uneven weld joints and limited welding quality.

[0040] Combine the following Figures 1 to 9 Embodiments of the present invention are described.

[0041] This embodiment relates to a plate strip welding machine, comprising:

[0042] frame;

[0043] The clamping device 1 comprises a clamping mechanism 12, wherein the clamping mechanism 12 comprises a clamping plate base frame 121, a clamping plate top plate 123, a clamping plate pad 122 and a clamping plate driver 124; the clamping plate base frame 121 is arranged on the frame, the clamping plate pad 122 is arranged on the clamping plate base frame 121, the clamping plate pad 122 comprises a supporting plate surface, and the supporting plate surface is provided with a plurality of space-avoiding holes 1221 arranged at intervals; the clamping plate top plate 123 is located above the clamping plate pad 122, and a welding through hole 1231 is formed on the clamping plate top plate 123, and the welding through hole 1231 is connected to the space-avoiding hole 1221; the clamping plate driver 124 is arranged on the clamping plate base frame 121, and the clamping plate driver 124 is drivingly connected to the clamping plate top plate 123, so as to drive the clamping plate top plate 123 to move toward the clamping plate pad 122;

[0044] A welding device 2, wherein the welding device 2 comprises a welding base 11 and a welding gun transverse movement mechanism, wherein the welding base 11 is fixedly connected to the frame, and the welding gun transverse movement mechanism comprises a first welding gun transverse movement slide column 211, a second welding gun transverse movement slide column 212, a welding gun transverse movement slide table 213 and a welding gun transverse movement drive assembly, wherein the first welding gun transverse movement slide column 211 and the second welding gun transverse movement slide column 212 are both arranged on the welding base 11, and the first welding gun transverse movement slide column 211 and the second welding gun transverse movement slide column 212 are arranged spaced apart in the front and rear directions, and the front and rear sides of the welding gun transverse movement slide table 213 are respectively slidably connected to the first welding gun transverse movement slide column 211 and the second welding gun transverse movement slide column 212, and the welding gun transverse movement drive assembly drives the welding gun transverse movement slide table 213 to slide along the first welding gun transverse movement slide column 211 and the second welding gun transverse movement slide column 212.

[0045] By equipping the clamping pad 122 with the air avoidance holes 1221, the welding slag generated during the welding process falls out through the air avoidance holes 1221, which can effectively reduce the impact of the welding slag on the flatness of the support plate surface and reduce the impact on the flatness of the weld; in addition, the two sides of the welding gun transverse slide 213 in the welding device 2 are respectively stably supported by the first welding gun transverse slide 211 and the second welding gun transverse slide 212 and are not easy to shake, which is beneficial for the second welding gun transverse slide to stably support the welding gun mechanism and is beneficial to improving the welding accuracy of the welding gun mechanism.

[0046] Reference Figures 1 to 6 The clamping device 1 also includes a front support mechanism 13, which includes a support column driving component 131 and a front support column 132. The support column driving component 131 is arranged on the welding base 11, and the front support column 132 is rotatably connected to the welding base 11. The support column driving component 131 is drivingly connected to the front support column 132. The front support mechanism 13 is equipped, and the front support column 132 is driven to rotate by the support column driving component 131. After welding is completed, the front support column 132 swings downward to leave the sheet material, reducing the friction between the sheet material surface and the front support column 132, and reducing the chance of scratches on the sheet surface.

[0047] In addition to reducing the friction of the sheet metal, the design of the front support mechanism 13 also makes it easy for the automatic welding clamping device 1 to be connected with other upstream equipment. When the sheet metal enters above the front support column 132, the support column driver drives the front support column 132 to swing upward, thereby conveniently guiding the sheet metal to the clamping pad.

[0048] The front support mechanism 131 further includes a guide 133, which is disposed on the welding base 11 and is located between the clamping plate 122 and the front support column 132. A guide surface 1331 is formed on a side of the guide 133 adjacent to the front support column 132, and the guide surface 1331 extends upward from a side adjacent to the front support column 132 to a side adjacent to the clamping plate 122. The guide 133 is disposed between the front support column 132 and the clamping plate 122 to transitionally connect the front support column 132 and the clamping plate 122, so as to help the sheet metal be more accurately positioned between the clamping plate top plate 123 and the clamping plate 122, thereby improving the positioning accuracy of the sheet metal.

[0049] Furthermore, the front support mechanism 13 also includes a movable wheel component, which includes a support block 134, a slide bar, a movable shaft, a movable wheel spring 135 and a roller 136. The support block 134 is arranged on the welding base 11, the slide bar extends upward to the top of the clamping plate 122, the slide bar is fixed to the support block 134, the movable shaft is slidably connected to the slide bar, the movable wheel spring 135 is arranged between the support block 134 and the movable shaft, and the roller 136 is rotatably connected to the movable shaft. The roller 136 is supported by the movable shaft to the top of the clamping plate 122 to pad the sheet material. When the sheet material enters between the clamping plate top plate 123 and the clamping plate 122, the roller 136 pads the sheet material to further reduce the scratching of the sheet material. The movable wheel spring 135 disposed between the support block 134 and the movable shaft can press down the roller 136 when the clamp top plate 123 is pressed down, so as to keep the sheet material straight and reduce the warping of the sheet material.

[0050] The clamping mechanism 12 is provided with a rear supporting mechanism 14 on the side away from the front supporting mechanism 13. The rear supporting mechanism 14 includes a lifting drive 141, a supporting roller support 142 and a supporting roller 143. The lifting drive 141 is provided on the welding base 11. The lifting drive 141 is drivingly connected to the supporting roller support 142, and the supporting roller 143 is rotatably connected to the supporting roller support 142. The lifting drive 141, the supporting roller support 142 and the supporting roller 143 are configured to form a lifting and lowering supporting roller 143 structure. When the sheet material is pushed into the clamping plate pad 122 via the side where the rear supporting mechanism 14 is located, the lifting drive 141 lifts the supporting roller 143 to conveniently guide the sheet material to the clamping plate pad 122, making it more convenient to load the sheet material into the clamping mechanism 12. In addition, the rear supporting mechanism 14 can also be used as a transition support to dock with peripheral equipment to achieve automated assembly line processing.

[0051] Furthermore, the front support mechanism 13 also includes a front feed sensor 137, which is arranged on the front support column 132 and is electrically connected to the support column driving member 131. The front feed sensor 137 is electrically connected to the support column driving member 131. When the front feed sensor 137 identifies the entry of the sheet material, it drives the front support column 132 to swing and lift the sheet material through a signal, automatically identifies the sheet material and guides the sheet material to swing upward to the clamping plate 122. After the guidance is completed, the support column driving member 131 drives the front support column 132 to swing downward, reducing the contact between the front support column 132 and the sheet material, and reducing the chance of scratching the sheet material. The front feed sensor 137 is arranged on the front support column 132, and there is no need to configure a pillar structure to arrange the position of the front feed sensor 137, which simplifies the design structure. In addition, the front support mechanism 13 and the front feed sensor 137 cooperate to play the role of fixed-length cutting and positioning of the sheet material. Specifically, the sheet material is transported from the upstream of the front support assembly to the top surface of the front support column 132 until the front feed sensor 137 signal triggers a stop, and then the upstream peripheral cutting device cuts at the front side of the front support assembly to complete the fixed-length cutting.

[0052] Furthermore, the clamping device 1 also includes a guide mechanism 15, which includes a first guide piece 151, a guide slide 152, a guide slide column 153, a second guide piece 154 and a guide driving component 155. The first guide piece 151 is vertically arranged on the welding base 11, the guide slide column 153 is laterally fixed to the welding base 11, the guide slide 152 is slidably connected to the guide slide column 153, the second guide piece 154 is vertically arranged on the guide slide 152, and the guide driving component 155 is arranged on the welding base 11. The guide driving component 155 is drivingly connected to the guide slide 152, driving the guide slide 152 to slide along the guide slide column 153. A first guide member 151 and a second guide member 154 are configured to extend vertically, and the sheet material can be positioned horizontally when entering the clamping mechanism 12 through the guide member 152. A guide slide 152 is configured to drive the second guide member 154 to move. The position of the second guide member 154 can be easily changed under the drive of the guide driving member 155, thereby changing the width between the first guide member 151 and the second guide member 154, and adjusting according to sheets of different widths. In this embodiment, the guide mechanism 15 is arranged on the side of the rear support mechanism 14 facing away from the clamping mechanism 12, and guides the sheet material before entering the rear support mechanism 14. In this embodiment, the first guide member 151 and the second guide member 154 are both roller components, and the use of roller components can reduce resistance when the sheet material enters.

[0053] Furthermore, the edge guide mechanism 15 also includes an edge guide sensor 156, which is arranged on the edge guide slide 152, and is used to identify the edge position of the sheet material. The edge guide sensor 156 is arranged on the edge guide slide 152, and when the edge guide slide 152 is driven to move by the edge guide driving component 155, the edge guide sensor 156 timely feeds back the edge position of the sheet material, and the adjustment is more convenient. Furthermore, the edge guide sensor 156 can also be connected to the edge guide driving component 155 through an electrical signal, so that the edge guide driving component 155 automatically adjusts the position of the second edge guide member 154 according to the edge position of the sheet material fed back by the edge guide sensor 156. In this embodiment, the edge guide sensor 156 adopts a through-beam photoelectric sensor. In other embodiments, other sensors such as infrared sensors can also be used.

[0054] Furthermore, the guide edge driving component 155 includes a guide edge driving motor, a guide edge screw and a guide edge nut. The guide edge driving motor is arranged on the welding base 11, the guide edge driving motor is drivingly connected to the guide edge screw, the guide edge nut is arranged on the guide edge slide 152, and the guide edge screw is threadedly connected to the guide edge nut. When the guide edge driving motor drives the guide edge screw to rotate, the guide edge slide 152 can be driven to move along the guide edge slide column 153 through the guide edge nut. The use of the guide edge driving motor for adjustment has the advantages of fast adjustment action and high adjustment accuracy.

[0055] Furthermore, the support column driving member 131 includes a support column linear driver, and the fixed end and the driving end of the support column linear driver are respectively hinged to the welding base 11 and the front support column 132. Therefore, when the support column linear driver moves to extend and retract, the front support column 132 can be driven to swing and rotate, and the swing of the front support column 132 is simply achieved by adopting this solution.

[0056] Furthermore, the welding base 11 is provided with a connecting support plate 16, and the connecting support plate 16 is provided with an elongated through hole 161. By configuring the connecting support plate 16, the entire automatic welding clamping device 1 can be conveniently connected with an external device in a modular manner by means of the connecting support plate 16. In addition, by means of the elongated through hole 161, it is also possible to conveniently perform leveling by means of the elongated through hole 161.

[0057] In addition, the clamping mechanism 12 further includes a cushion 125, which is located below the clamp pad 122 and supports the clamp pad 122. The cushion 125 is provided on the welding base 11, and the air avoidance hole 1221 passes through the clamp pad 122. A welding slag groove is formed on the cushion 125, and a slag drop port 1251 is provided on the welding slag groove to communicate with the air avoidance hole 1221. A welding slag groove is provided below the air avoidance hole 1221 to increase the storage space for welding slag, and has the ability to accommodate larger and more welding slag, further reducing the impact of welding slag on the support plate surface, and at the same time helping to reduce the number of times of cleaning welding slag.

[0058] Further, the welding slag trough is connected to all the air-avoiding holes 1221. The welding slag trough is connected to all the air-avoiding holes 1221, which is conducive to simplifying the welding slag trough structure, and the subsequent cleaning of the welding slag trough is also more convenient.

[0059] Furthermore, a cleaning port 1252 is provided on the side wall of the welding slag trough. The cleaning port 1252 is provided on the welding slag trough, so that the welding slag can be cleaned more conveniently.

[0060] Furthermore, cleaning ports 1252 are provided on both side walls of the welding slag trough, and the two cleaning ports 1252 are formed on both side walls of the welding slag trough along the length direction of the welding slag trough, so that both sides of the welding slag trough are connected to the outside. The cleaning ports 1252 are arranged in the above manner to form a welding slag trough with two sides connected. When the welding slag needs to be removed, it can be cleaned by blowing air into one of the cleaning ports 1252 or inserting a cleaning head, which is more convenient.

[0061] Furthermore, the cushion member 125 is a pipe. The cushion member 125 directly adopts a pipe, which has the advantage of easy availability of materials and is conducive to reducing the overall cost.

[0062] In addition, the clamping device 1 also includes a clamp lifting guide column 127 and a clamp lifting guide sleeve 126, the clamp lifting guide sleeve 126 is fixedly connected to the clamp base frame 121, and the clamp lifting guide column 127 is fixedly connected to the clamp top plate 123. By configuring the clamp lifting guide column 127 and the clamp lifting guide sleeve 126, when the clamp driver 124 drives the clamp pad 122 and the clamp pad 122 to move more smoothly and with higher movement accuracy, it can better ensure that the clamp top plate 123 and the clamp pad 122 press the two sheets flush, ensure that the height of the sheets at the weld is consistent, and ensure that there is no leakage between the welded sheets. The clamp driver 124 can be a pneumatic push rod, an electric push rod, a hydraulic push rod, a linear module, a linear module, a screw mechanism, etc., and its main effect is to provide an output end for linear motion. In this embodiment, the clamp driver 124 adopts a cylinder, which has the advantages of clean energy and low cost.
