Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel welding, and particularly relates to a clamping and welding device for special-shaped stainless steel parts. Background Art

[0002] Special-shaped stainless steel parts refer to stainless steel components with irregular shapes that have been specially processed or customized. These parts are usually used in application scenarios that require special structures, dimensions, or shapes. Different from standard common shapes such as stainless steel plates, tubes, and profiles, special-shaped stainless steel parts may have more complex or unique designs. Special-shaped stainless steel parts are widely used in many fields, especially in engineering projects that require corrosion resistance, high strength, and special shapes. When welding special-shaped stainless steel parts, multiple clamps are usually required for clamping, and the welding trajectory is not a straight line; the existing stainless steel part clamping and welding devices in the prior art usually cannot stably clamp special-shaped stainless steel parts, resulting in poor welding quality. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a clamping and welding device for special-shaped stainless steel parts, including a base mechanism. The base mechanism includes a bottom plate. There are two clamping mechanisms for clamping special-shaped stainless steel parts and an operating mechanism for welding special-shaped stainless steel parts arranged on the base mechanism. The clamping mechanism includes a lifting frame, and the operating mechanism includes a rack frame. The rack frame is fixedly installed on the bottom plate;

[0004] The base mechanism includes a movable seat and a fixed seat. The lifting frames of the two clamping mechanisms are respectively slidably installed in the movable seat and the fixed seat.

[0005] Furthermore, the base mechanism further includes a fixed frame fixedly installed on the bottom plate. The fixed seat is fixedly installed on the fixed frame. A cylindrical sleeve is fixedly installed on the fixed seat. Several bottom wheels are rotatably installed below the movable seat. The bottom wheels roll on the bottom plate. An inner sliding plate is fixedly installed on the movable seat. The inner sliding plate is slidably installed with the fixed frame. An electric cylinder is fixedly installed on the movable seat. An electric cylinder spring is fixedly installed on the output end of the electric cylinder. The other end of the electric cylinder spring is fixedly installed with the fixed seat.

[0006] After the clamping mechanism clamps the special-shaped stainless steel parts to be welded, the electric cylinder contracts, driving the movable seat and the inner sliding plate to slide along the fixed frame, making the movable seat close to the fixed seat. The special-shaped stainless steel parts on the clamping mechanism on the fixed seat are butted against the special-shaped stainless steel parts on the clamping mechanism on the movable seat. After the two special-shaped stainless steel parts are butted, the electric cylinder continues to contract, causing the electric cylinder spring to be stretched, so that the two special-shaped stainless steel parts remain tightly pressed against each other.

[0007] Further, the clamping mechanism further includes a vertical electric cylinder fixedly installed on the lifting frame. A rotating block is fixedly installed on the output end of the vertical electric cylinder, and a rotating rod is rotatably installed on the rotating block.

[0008] Further, the clamping mechanism further includes three clamping modules. The clamping module includes a lower clamping block, on which an upper guide post is fixedly installed. An upper clamping block is slidably installed on the upper guide post, and a guide post spring is arranged between the upper guide post and the upper clamping block.

[0009] Further, the lower clamping block of the clamping module beside the lifting frame is fixedly installed with the lifting frame. A lifting block is fixedly installed below the lower clamping block of the clamping module farthest from the lifting frame. A moving seat is slidably installed below the lifting block. A plurality of moving rollers are rotatably installed at the bottom of the moving seat. The moving rollers of the clamping mechanism on one side of the fixed seat roll on the bottom plate, and the moving rollers of the clamping mechanism on one side of the movable seat roll on the inner sliding plate. An inner spring is arranged between the lifting block and the moving seat. An extending column is fixedly installed on the upper clamping block of the clamping module farthest from the lifting frame, and the extending column is rotatably installed with the rotating rod.

[0010] Further, an intermediate spring is arranged between the lower clamping block of the middle clamping module and the lower clamping block of the clamping module on the lifting block.

[0011] Further, a connecting block is fixedly installed on the upper clamping block of the clamping module on the lifting block. An inner chain is fixedly installed on the connecting block. The inner chain passes through the upper clamping blocks of the other two clamping modules. An inner connecting block is fixedly installed on the upper clamping block of the middle clamping module, and an outer chain is fixedly installed on the inner connecting block. The outer chain passes through the upper clamping block of the clamping module on the lifting frame.

[0012] During use, the special-shaped stainless steel parts to be welded are respectively placed between the upper and lower clamping blocks of the two clamping mechanisms. The clamping force is applied through the upper guide posts. The vertical electric cylinder contracts, drives the rotating rod to rotate through the rotating block, and then drives the extending column and the outermost clamping module to move outward. The outermost clamping module drives the middle clamping module to move outward through the intermediate spring. The three clamping modules are prevented from displacing along the telescopic direction of the electric cylinder through the inner chain and the outer chain. The outermost clamping module can be lifted through the inner spring. The clamping mechanism can clamp special-shaped parts with different local thicknesses, and the clamping stability of the special-shaped stainless steel parts is improved through the three clamping modules.

[0013] Further, the working mechanism includes a vertical rack fixedly installed on the rack frame. A moving wheel is rotatably installed on the bottom plate. A moving block is rotatably installed on the moving wheel. A cross frame is fixedly installed on the moving block. A motor is fixedly installed on the cross frame, and a motor gear is fixedly installed on the motor shaft of the motor.

[0014] Further, a top block is fixedly installed on the cross frame. A docking gear is rotatably installed on the top block. A probe is slidably installed on the top block. A slope is provided on the probe. A probe spring is provided between the probe and the top block. A motor base is rotatably installed on the top block. A chute is provided on the motor base. The motor base and the probe are rotatably installed through the chute. A docking motor is fixedly installed on the motor base. An output gear is fixedly installed on the motor shaft of the docking motor. The docking gear meshes with the vertical rack.

[0015] Further, a mounting frame is fixedly installed on the cross frame. A support frame is slidably installed on the mounting frame. A support spring is provided between the support frame and the mounting frame. A support wheel is rotatably installed on the support frame. A welding torch is fixedly installed on the support frame. A horizontal rack is fixedly installed below the mounting frame. The horizontal rack meshes with the motor gear.

[0016] After the special-shaped stainless steel part is clamped on the clamping mechanism on one side of the fixed seat, the special-shaped stainless steel part will push the probe to slide along the top block, and the probe spring is compressed, driving the motor base to rotate relative to the top block, so that the output gear meshes with the docking gear. After the special-shaped stainless steel part is completely clamped, the docking motor is started to drive the output gear to rotate, thereby driving the docking gear to rotate, and then driving the cross frame and the moving block to move relative to the bottom plate through the moving wheels. When the slope end of the probe leaves the edge of the special-shaped stainless steel part, the probe spring rebounds, causing the probe to reset, so that the output gear is disengaged from the docking gear, indicating that this position is the welding position. Subsequently, the electric cylinder contracts, causing the two special-shaped stainless steel parts to contact. The support spring makes the support wheel always contact the special-shaped stainless steel part. The motor rotates to drive the motor gear to rotate, and then drives the mounting frame to slide along the cross frame through the horizontal rack, and welds the special-shaped stainless steel part with the welding torch.

[0017] The beneficial effects of the present invention compared with the prior art are as follows: (1) The base mechanism provided by the present invention can drive the two clamping mechanisms to bring the special-shaped stainless steel parts to be welded into contact, and under the action of the electric cylinder spring, the two special-shaped stainless steel parts to be welded are kept in close contact, improving the welding quality; (2) The clamping mechanism provided by the present invention can better clamp the special-shaped stainless steel parts to be welded through three clamping modules, and a certain amount of displacement in the height direction and the horizontal direction can be carried out between the three clamping modules, improving the clamping stability; (3) The working mechanism provided by the present invention can make the welding torch keep in close contact with the special-shaped stainless steel parts to be welded, further improving the welding quality.

Detailed implementation manners

[0027] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0028] Example: Refer to Figures 1 - 8, A special-shaped stainless steel part clamping and welding device, including a base mechanism. The base mechanism includes a bottom plate 101. There are two clamping mechanisms for clamping special-shaped stainless steel parts and an operating mechanism for welding special-shaped stainless steel parts on the base mechanism. The clamping mechanism includes a lifting frame 203, and the operating mechanism includes a rack frame 301. The rack frame 301 is fixedly installed on the bottom plate 101;

[0029] The base mechanism includes a movable seat 102 and a fixed seat 109. The lifting frames 203 of the two clamping mechanisms are respectively slidably installed in the movable seat 102 and the fixed seat 109.

[0030] As Figure 2 , Figure 3 shown, the base mechanism further includes a fixed frame 106 fixedly installed on the bottom plate 101. The fixed seat 109 is fixedly installed on the fixed frame 106. A cylindrical sleeve 108 is fixedly installed on the fixed seat 109. A plurality of bottom wheels 103 are rotatably installed below the movable seat 102. The bottom wheels 103 roll on the bottom plate 101. An inner sliding plate 104 is fixedly installed on the movable seat 102. The inner sliding plate 104 is slidably installed with the fixed frame 106. An electric cylinder 105 is fixedly installed on the movable seat 102. An electric cylinder spring 107 is fixedly installed on the output end of the electric cylinder 105. The other end of the electric cylinder spring 107 is fixedly installed with the fixed seat 109.

[0031] After the clamping mechanism clamps the special-shaped stainless steel part to be welded, the electric cylinder 105 contracts, driving the movable seat 102 and the inner sliding plate 104 to slide along the fixed frame 106, so that the movable seat 102 is close to the fixed seat 109. The special-shaped stainless steel part of the clamping mechanism on the fixed seat 109 is butted against the special-shaped stainless steel part of the clamping mechanism on the movable seat 102. After the two special-shaped stainless steel parts are butted, the electric cylinder 105 continues to contract, causing the electric cylinder spring 107 to be stretched, so that the two special-shaped stainless steel parts are kept closely attached.

[0032] As Figure 4 , Figure 5 shown, the clamping mechanism further includes a vertical electric cylinder 205 fixedly installed on the lifting frame 203. A rotating block 206 is fixedly installed on the output end of the vertical electric cylinder 205. A rotating rod 207 is rotatably installed on the rotating block 206.

[0033] As Figure 4 , Figure 5 shown, the clamping mechanism further includes three clamping modules. The clamping module includes a lower clamping block 212. An upper guide post 213 is fixedly installed on the lower clamping block 212. An upper clamping block 208 is slidably installed on the upper guide post 213. A guide post spring 214 is arranged between the upper guide post 213 and the upper clamping block 208.

[0034] As Figure 4 , Figure 5As shown in the figure, the lower clamping block 212 of the clamping module beside the lifting frame 203 is fixedly installed with the lifting frame 203. Below the lower clamping block 212 of the clamping module farthest from the lifting frame 203, a lifting block 210 is fixedly installed. A moving seat 201 is slidably installed below the lifting block 210. A plurality of moving rollers 202 are rotatably installed at the bottom of the moving seat 201. The moving rollers 202 of the clamping mechanism on one side of the fixed seat 109 roll on the bottom plate 101, and the moving rollers 202 of the clamping mechanism on one side of the movable seat 102 roll on the inner slide plate 104. An inner spring 211 is arranged between the lifting block 210 and the moving seat 201. An extension column 209 is fixedly installed on the upper clamping block 208 of the clamping module farthest from the lifting frame 203, and the extension column 209 is rotatably installed with the rotating rod 207.

[0035] As Figure 4 , Figure 5 shown in the figure, an intermediate spring 218 is arranged between the lower clamping block 212 of the clamping module in the middle and the lower clamping block 212 of the clamping module on the lifting block 210.

[0036] As Figure 4 , Figure 5 shown in the figure, a connecting block 215 is fixedly installed on the upper clamping block 208 of the clamping module on the lifting block 210. An inner chain 204 is fixedly installed on the connecting block 215. The inner chain 204 passes through the upper clamping blocks 208 of the other two clamping modules. An inner connecting block 216 is fixedly installed on the upper clamping block 208 of the clamping module in the middle. An outer chain 217 is fixedly installed on the inner connecting block 216. The outer chain 217 passes through the upper clamping block 208 of the clamping module on the lifting frame 203.

[0037] During use, the special-shaped stainless steel parts to be welded are respectively placed between the upper clamping block 208 and the lower clamping block 212 of the two clamping mechanisms. A clamping force is applied through the upper guide post 213. The vertical electric cylinder 205 contracts, drives the rotating rod 207 to rotate through the rotating block 206, and drives the extension column 209 and the outermost clamping module to move outward. The outermost clamping module drives the middle clamping module to move outward through the intermediate spring 218. The inner chain 204 and the outer chain 217 ensure that the three clamping modules do not displace along the telescopic direction of the electric cylinder 105. The inner spring 211 enables the outermost clamping module to lift. The clamping mechanism can clamp special-shaped parts with different local thicknesses, and the three clamping modules are used to improve the clamping stability of the special-shaped stainless steel parts.

[0038] As Figures 6 - 8As shown in the figure, the working mechanism includes a vertical rack 302 fixedly installed on the rack 301. A moving wheel 304 is rotatably installed on the bottom plate 101. A moving block 303 is rotatably installed on the moving wheel 304. A cross frame 321 is fixedly installed on the moving block 303. A motor 305 is fixedly installed on the cross frame 321. A motor gear 306 is fixedly installed on the motor shaft of the motor 305.

[0039] As Figures 6 - 8 shown in the figure, a top block 308 is fixedly installed on the cross frame 321. A docking gear 309 is rotatably installed on the top block 308. A probe 310 is slidably installed on the top block 308. A slope is provided on the probe 310. A probe spring 311 is provided between the probe 310 and the top block 308. A motor seat 312 is rotatably installed on the top block 308. A chute 313 is provided on the motor seat 312. The motor seat 312 and the probe 310 are rotatably installed through the chute 313. A docking motor 314 is fixedly installed on the motor seat 312. An output gear 315 is fixedly installed on the motor shaft of the docking motor 314. The docking gear 309 meshes with the vertical rack 302.

[0040] As Figures 6 - 8 shown in the figure, a mounting frame 316 is fixedly installed on the cross frame 321. A support frame 317 is slidably installed on the mounting frame 316. A support spring 318 is provided between the support frame 317 and the mounting frame 316. A support wheel 319 is rotatably installed on the support frame 317. A welding torch 320 is fixedly installed on the support frame 317. A horizontal rack 307 is fixedly installed below the mounting frame 316. The horizontal rack 307 meshes with the motor gear 306.

[0041] After the special-shaped stainless steel part is clamped to the clamping mechanism on one side of the fixed seat 109, the special-shaped stainless steel part will push the probe 310 to slide along the top block 308, and the probe spring 311 will be compressed, driving the motor seat 312 to rotate relative to the top block 308, so that the output gear 315 meshes with the docking gear 309. After the special-shaped stainless steel part is completely clamped, the docking motor 314 is started to drive the output gear 315 to rotate, thereby driving the docking gear 309 to rotate, and then driving the cross frame 321 and the moving block 303 to move relative to the bottom plate 101 through the moving wheel 304. When the slope end of the probe 310 leaves the edge of the special-shaped stainless steel part, the probe spring 311 rebounds, causing the probe 310 to reset, so that the output gear 315 disengages from the docking gear 309, indicating that this position is the welding position. Subsequently, the electric cylinder 105 contracts, making the two special-shaped stainless steel parts contact. The support spring 318 makes the support wheel 319 always contact with the special-shaped stainless steel part. The motor 305 rotates to drive the motor gear 306 to rotate, and then drives the mounting frame 316 to slide along the cross frame 321 through the horizontal rack 307, and welds the special-shaped stainless steel part with the welding torch 320.

[0042] The working principle of a special-shaped stainless steel part clamping and welding device disclosed by the present invention is as follows: During use, the special-shaped stainless steel parts to be welded are respectively placed between the upper clamping block 208 and the lower clamping block 212 of the two clamping mechanisms. A clamping force is applied through the upper guide post 213. The vertical electric cylinder 205 contracts, driving the rotating rod 207 to rotate through the rotating block 206, thereby driving the protruding column 209 and the outermost clamping module to move outward. The outermost clamping module drives the middle clamping module to move outward through the middle spring 218. The three clamping modules are prevented from displacing along the telescopic direction of the electric cylinder 105 through the inner chain 204 and the outer chain 217. The outermost clamping module can be lifted and lowered through the inner spring 211. The clamping mechanism can clamp special-shaped parts with different local thicknesses, and the clamping stability of the special-shaped stainless steel parts is improved through the three clamping modules. After the special-shaped stainless steel part is clamped to the clamping mechanism on one side of the fixed seat 109, the special-shaped stainless steel part will push the probe 310 to slide along the top block 308, compressing the probe spring 311, driving the motor seat 312 to rotate relative to the top block 308, so that the output gear 315 meshes with the docking gear 309. After the special-shaped stainless steel part is completely clamped, the docking motor 314 is started, driving the output gear 315 to rotate, thereby driving the docking gear 309 to rotate, and then driving the cross frame 321 and the moving block 303 to move relative to the bottom plate 101 through the moving wheels 304. When the sloping end of the probe 310 leaves the edge of the special-shaped stainless steel part, the probe spring 311 rebounds, resetting the probe 310, so that the output gear 315 disengages from the docking gear 309, indicating that this position is the welding position. Subsequently, the electric cylinder 105 contracts, driving the movable seat 102 and the inner sliding plate 104 to slide along the fixed frame 106, bringing the special-shaped stainless steel part on the clamping mechanism of the movable seat 102 close to the special-shaped stainless steel part on the clamping mechanism of the fixed seat 109. When the two special-shaped stainless steel parts are docked, the electric cylinder 105 continues to contract, stretching the electric cylinder spring 107, so that the two special-shaped stainless steel parts are kept in close contact. The support spring 318 keeps the support wheel 319 in contact with the special-shaped stainless steel part all the time. The motor 305 rotates, driving the motor gear 306 to rotate, and then driving the mounting frame 316 to slide along the cross frame 321 through the cross rack 307, and welding the special-shaped stainless steel part with the welding torch 320.

[0043] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
