Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly relates to a butt welding device for stainless steel plates. Background Art

[0002] Stainless steel plates are a widely used and durable material, with a wide range of applications, from kitchen utensils to construction projects. In order to make full use of their properties, it is usually necessary to weld stainless steel plates together. Stainless steel plate welding is a process of connecting two stainless steel plates together using heat and pressure. Welding forms a strong and permanent bond between metals, enabling them to function as a whole. The butt joint between two stainless steel plates is an important factor determining the welding quality. In the prior art, most of the welding of stainless steel plates is handheld, which will result in welding errors, etc., making it difficult to ensure the stability of the stainless steel plates during welding and the accuracy of the welding position, affecting the welding quality of the stainless steel plates, and the welding efficiency is extremely low.

A clamping assembly is arranged on the chassis. The clamping assembly includes a butt welding workbench. The clamping assembly is used for positioning and clamping the stainless steel plates in all directions. A feeding mechanism is arranged in front of the clamping assembly. The feeding mechanism includes a pushing rotating shaft. The feeding mechanism can adjust the clamping of the stainless steel plates and the pushing and discharging after welding. A welding mechanism is arranged above the clamping assembly. The welding mechanism is used to complete the precise welding treatment of the stainless steel plates.

[0004] Further, the clamping assembly includes a butt welding workbench fixedly installed on the chassis. Stainless steel plates are placed at both ends of the butt welding workbench.

Detailed Implementation Manner

[0016] As Figures 1 - 6 shown, a stainless steel plate docking and welding device includes a chassis 101, a clamping assembly is arranged on the chassis 101, the clamping assembly includes a docking workbench 102, the clamping assembly is used for positioning and clamping the stainless steel plate in all directions, a pushing mechanism is arranged in front of the clamping assembly, the pushing mechanism includes a pushing rotating shaft 201, the pushing mechanism can adjust the clamping of the stainless steel plate and the pushing and discharging after welding, a welding mechanism is arranged above the clamping assembly, and the welding mechanism is used for completing the precise welding treatment of the stainless steel plate.

[0017] As Figures 1 - 6 shown, the clamping assembly includes a docking workbench 102 fixedly installed on the chassis 101, stainless steel plates 118 are placed at both ends of the docking workbench 102, a motor 103 is fixedly installed at the bottom end of the chassis 101, a motor shaft 104 is rotatably installed at the movable end of the motor 103, a material blocking block 115 is fixedly installed on the motor shaft 104, a connecting belt pulley 119 is rotatably installed above the material blocking block 115, a rotating shaft 112 is rotatably installed on the chassis 101, a belt pulley I 117 is fixedly installed on the rotating shaft 112, a driving gear 113 is fixedly installed at the top end of the rotating shaft 112, a fixed chute 116 is fixedly installed on the side of the chassis 101, a sliding rack 114 is slidably installed on the fixed chute 116, two groups of material blocking blocks 115 are arranged on the sliding rack 114, and the sliding rack 114 meshes with the driving gear 113.

[0018] As Figures 1 - 6As shown in the figure, a right clamping chute 106 and a left clamping chute 107 are provided below the docking workbench 102. The right clamping chute 106 and the left clamping chute 107 are fixedly installed on the chassis 101. A transverse rack II 109 is slidably installed on the right clamping chute 106. The top end of the transverse rack II 109 is fixedly installed with a transverse baffle I 110. A transverse rack I 108 is slidably installed on the left clamping chute 107. The top end of the transverse rack I 108 is fixedly installed with a transverse baffle II 111. The transverse gear 105 meshes with the transverse rack I 108 and the transverse rack II 109.

[0019] Place the two groups of stainless steel plates to be welded at both ends of the docking workbench 102. Then start the motor 103. The motor 103 drives the motor shaft 104 to rotate. The rotation of the motor shaft 104 drives the transverse gear 105 to rotate, thereby driving the relative sliding of the transverse rack I 108 and the transverse rack II 109, so as to relatively push and clamp the stainless steel plates, thereby achieving the docking of the two groups of stainless steel plates.

[0020] As Figures 4 - 6 As shown in the figure, the pushing mechanism includes a transmission pulley II 203 fixedly installed on the pushing rotating shaft 201. A transmission belt 204 is wound around the transmission pulley II 203 and the transmission pulley I 117. A push plate support frame 202 is fixedly installed in front of the pushing rotating shaft 201. The top end of the pushing rotating shaft 201 is rotatably installed with a connecting plate 205. One end of the connecting plate 205 is rotatably installed with an upper connecting rod 206. The other end of the connecting plate 205 is rotatably installed with a lower connecting rod 208. An upper baffle plate 207 is rotatably installed on the upper connecting rod 206. A lower pushing plate 209 is rotatably installed on the lower connecting rod 208. The lower connecting rod 208 and the lower pushing plate 209 are slidably installed inside the push plate support frame 202.

[0021] While the motor shaft 104 is rotating, the motor shaft 104 synchronously drives the connecting pulley 119 to rotate. The connecting pulley 119 drives the transmission pulley I 117 and the transmission pulley II 203 to rotate through the transmission belt 204. The rotation of the transmission pulley I 117 drives 113 to rotate, thereby driving the sliding rack 114 to slide towards the transverse baffle II 111. At the same time, the transmission pulley II 203 drives the pushing rotating shaft 201 to rotate, thereby driving the connecting plate 205 to rotate. When the connecting plate 205 rotates forward, it drives the upper baffle plate 207 to push forward, so as to clamp one side of the stainless steel plate. The baffle block 115 also slides to the middle position between the two groups of stainless steel plates at the same time, so as to clamp the other side, thereby achieving a full range of clamping.

[0022] As Figures 1 - 3As shown in the figure, the welding mechanism includes a welding support frame 301 fixedly installed on the chassis 101. A lead screw support frame 303 is fixedly installed on the welding support frame 301. A welding motor 302 is fixedly installed on the welding support frame 301. A lead screw shaft is rotatably installed at the movable end of the welding motor 302. A lead screw 304 is rotatably installed at the front end of the lead screw shaft. A welding gun 305 is slidably installed on the lead screw 304.

[0023] After the stainless steel plates are butted, start the welding motor 302. The welding motor 302 drives the lead screw shaft to rotate. The rotation of the lead screw shaft drives the lead screw 304 to rotate, thereby driving the welding gun 305 to slide back and forth, so as to perform welding treatment on the stainless steel plates.

[0024] The working principle of a stainless steel plate butt welding device disclosed in the present invention is as follows: Place two groups of stainless steel plates to be welded at both ends of the butt welding workbench 102. Then start the motor 103. The motor 103 drives the motor shaft 104 to rotate. The rotation of the motor shaft 104 drives the transverse gear 105 to rotate, thereby driving the relative sliding of the transverse rack I 108 and the transverse rack II 109, so as to relatively push and clamp the stainless steel plates, thereby achieving the butt joint of the two groups of stainless steel plates. At the same time, the motor shaft 104 synchronously drives the connecting pulley 119 to rotate. The connecting pulley 119 drives the driving pulley I 117 and the driving pulley II 203 to rotate through the transmission belt 204. The rotation of the driving pulley I 117 drives the 113 to rotate, thereby driving the sliding rack 114 to slide towards the transverse baffle II 111. At the same time, the driving pulley II 203 drives the pushing rotating shaft 201 to rotate, thereby driving the connecting plate 205 to rotate. When the connecting plate 205 rotates forward, it drives the upper material baffle 207 to push forward, so as to clamp one side of the stainless steel plate. The material blocking block 115 also slides to the middle position between the two groups of stainless steel plates at the same time, so as to clamp the other side, thereby achieving clamping on all four sides. After clamping, start the welding motor 302. The welding motor 302 drives the lead screw shaft to rotate. The rotation of the lead screw shaft drives the lead screw 304 to rotate, thereby driving the welding gun 305 to slide back and forth, so as to perform welding treatment on the stainless steel plates. Then the motor 103 rotates in reverse, and the transverse rack I 108 and the transverse rack II 109 slide away from each other, so as to open the welded stainless steel plates. At the same time, the sliding rack 114 drives the material blocking block 115 back to the initial position, and the connecting plate 205 rotates in reverse, thereby driving the lower material pushing plate 209 to push forward, so as to perform blanking treatment on the welded stainless steel plates.
