Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel welding, and particularly relates to a multi-angle stainless steel part welding device. Background Art

[0002] Stainless steel is a common metal material in modern applications. Due to its excellent rust and corrosion resistance properties, it is widely used in various fields, and the base material can be adjusted to change the material properties according to the requirements of different fields. In the actual application process, due to different requirements, it is often necessary to cut and weld the material. For special-shaped materials, even manual welding cannot guarantee the welding quality. Therefore, a device that can meet multi-angle welding is needed to ensure the welding quality. The multi-angle stainless steel plate welding devices in the prior art cannot automatically move and weld along the weld seam. Each processing requires independent programming and cannot achieve automatic welding, resulting in poor automation. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a multi-angle stainless steel part welding device, including a main body mechanism for clamping stainless steel parts. The main body mechanism includes a bottom plate, and a welding mechanism for welding stainless steel and a moving mechanism for driving the welding mechanism to move are arranged on the main body mechanism. The moving mechanism includes a moving frame, and the welding mechanism includes a plurality of sliding columns.

[0004] The main body mechanism includes a welding frame, and a plurality of sliding columns are slidably installed on the welding frame.

[0005] Further, the main body mechanism further includes a plurality of vertical frames fixedly installed on the bottom plate. Two front and rear guide rails are fixedly installed on the vertical frames. A left and right guide rail is slidably installed on the front and rear guide rails. A sliding block is slidably installed on the left and right guide rails, and the welding frame is rotatably installed on the sliding block.

[0006] Further, two clamping sliders are slidably installed on the bottom plate. A clamping frame is fixedly installed on the clamping sliders. A clamping spring is arranged between the clamping sliders and the bottom plate.

[0007] During use, two stainless steel plates to be welded are placed on the bottom plate and pushed between the two clamping frames. The slope on the clamping frame pushes the clamping sliders and the clamping frame to slide outwards, so that the two stainless steel plates to be welded are kept in a butting state between the horizontal parts of the two clamping frames. The clamping spring is compressed, and the two stainless steel plates to be welded are clamped and butted by the two clamping frames.

[0008] When the moving mechanism drives the welding frame to move, the sliding block slides along the left and right guide rails, and the left and right guide rails slide along the front and rear guide rails.

[0009] Further, the moving mechanism includes a traveling shaft rotatably mounted below the moving frame. A lower transmission wheel and a moving wheel are fixedly mounted on the traveling shaft. The moving wheel rolls on the bottom plate. A motor frame is fixedly mounted on the moving frame. A moving motor is fixedly mounted on the motor frame. A motor bevel gear is fixedly mounted on the motor shaft of the moving motor. A gear shaft is rotatably mounted on the moving frame. An upper transmission wheel and a docking bevel gear are fixedly mounted on the gear shaft. The docking bevel gear meshes with the motor bevel gear. A transmission belt is wound around the upper transmission wheel and the lower transmission wheel.

[0010] Further, a lower connecting rod is rotatably mounted on the moving frame. An upper connecting rod is rotatably mounted on the lower connecting rod. The upper connecting rod is rotatably mounted on the welding frame. The welding frame is slidably mounted on the moving frame.

[0011] The moving motor drives the motor bevel gear to rotate, thereby driving the docking bevel gear, the gear shaft and the upper transmission wheel to rotate. The lower transmission wheel, the traveling shaft and the moving wheel are driven to rotate through the transmission belt, thereby driving the moving frame and the welding frame to move. When the stainless steel plate is inserted below the ball and the moving wheel, the sliding column slides a short distance along the welding frame, the moving wheel is lifted, driving the moving frame to rise. The lower connecting rod rotates relative to the moving frame, and the upper connecting rod rotates relative to the lower connecting rod, and the moving frame rises along the welding frame.

[0012] Further, the welding mechanism includes a ball rotatably mounted at the bottom of the sliding column. A lower rotating arm is rotatably mounted on the sliding column. An upper rotating arm is slidably mounted outside the lower rotating arm. An inner spring is provided between the upper rotating arm and the lower rotating arm. A welding torch seat is rotatably mounted on the upper rotating arm. A welding torch is fixedly mounted on the welding torch seat.

[0013] Further, a rotating frame is fixedly mounted below the welding frame. An insertion block is slidably mounted on the rotating frame. An upper disk is fixedly mounted on the insertion block. An insertion spring is provided between the upper disk and the rotating frame.

[0014] Further, a rotating rod is rotatably mounted on the rotating frame. A scroll spring is provided between the rotating rod and the rotating frame. A pressing rod is slidably mounted on the rotating rod. A pressing disk is fixedly mounted on the pressing rod. A pressing spring is provided between the pressing disk and the rotating rod.

[0015] The insertion spring causes the insertion block to insert into the weld of the stainless steel part. The pressing spring presses the pressing rod against the weld. When the welding frame moves, first the pressing rod moves along the weld. When the weld turns, it will cause the rotating rod to rotate relative to the rotating frame, and the scroll spring is twisted. A turning force is applied to the rotating frame and the welding frame through the scroll spring, and then the insertion block changes the advancing direction of the rotating frame and the welding frame. The movement of the moving frame drives the movement of the welding frame, and the two stainless steel plates are welded by the welding torch.

[0016] When the surface angle of the welded part changes, the sliding columns in the corresponding positions will be lifted to different degrees, thereby lifting the welding torch seat in this position through the lower rotating arm and the upper rotating arm to adjust the angle of the welding torch.

[0017] The beneficial effects of the present invention compared with the prior art are as follows: (1) The main mechanism provided by the present invention can butt and clamp the stainless steel plate to be welded, and is guided by the front and rear guide rails and the left and right guide rails to ensure the stability of the welding process and improve the welding quality; (2) The welding mechanism provided by the present invention enables the moving frame and the welding torch to move along the weld seam under the action of the pressing rod and the insertion block, realizing full-automatic multi-angle welding; (3) The welding mechanism provided by the present invention moves driven by the moving mechanism. When the surface angle of the welded part changes, the sliding columns in the corresponding positions will be lifted to different degrees, thereby lifting the welding torch seat in this position through the lower rotating arm and the upper rotating arm to adjust the angle of the welding torch, facilitating the welding operation.

Detailed Embodiment

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

[0028] Example: Refer to Figures 1-8 , a multi-angle stainless steel part welding device, including a main body mechanism for clamping stainless steel parts. The main body mechanism includes a bottom plate 101. A welding mechanism for welding stainless steel and a moving mechanism for driving the welding mechanism to move are provided on the main body mechanism. The moving mechanism includes a moving frame 201, and the welding mechanism includes a plurality of sliding columns 301;

[0029] The main body mechanism includes a welding frame 109, and a plurality of sliding columns 301 are slidably installed on the welding frame 109.

[0030] As Figure 2 shown, the main body mechanism further includes a plurality of vertical frames 102 fixedly installed on the bottom plate 101. Two front and rear guide rails 103 are fixedly installed on the vertical frames 102. A left and right guide rail 104 is slidably installed on the front and rear guide rails 103. A sliding block 105 is slidably installed on the left and right guide rails 104, and the welding frame 109 is rotatably installed on the sliding block 105.

[0031] As Figure 2 shown, two clamping sliders 106 are slidably installed on the bottom plate 101. A clamping frame 107 is fixedly installed on the clamping sliders 106, and a clamping spring 108 is provided between the clamping sliders 106 and the bottom plate 101.

[0032] When in use, place two stainless steel plates to be welded on the bottom plate 101 and push them between the two clamping frames 107. Through the slopes on the clamping frames 107, push the clamping sliders 106 and the clamping frames 107 to slide outwards, so that the two stainless steel plates to be welded are kept in a butting state and reach between the horizontal parts of the two clamping frames 107. The clamping springs 108 are compressed, and the two stainless steel plates to be welded are clamped and butted by the two clamping frames 107.

[0033] When the moving mechanism drives the welding frame 109 to move, the sliding block 105 slides along the left and right guide rails 104, and the left and right guide rails 104 slide along the front and rear guide rails 103.

[0034] As Figure 3 、 Figure 4 As shown in the figure, the moving mechanism includes a walking shaft 212 rotatably installed below the moving frame 201. A lower transmission wheel 211 and a moving wheel 202 are fixedly installed on the walking shaft 212. The moving wheel 202 rolls on the bottom plate 101. A motor frame 203 is fixedly installed on the moving frame 201. A moving motor 204 is fixedly installed on the motor frame 203. A motor bevel gear 205 is fixedly installed on the motor shaft of the moving motor 204. A gear shaft 208 is rotatably installed on the moving frame 201. An upper transmission wheel 209 and a docking bevel gear 210 are fixedly installed on the gear shaft 208. The docking bevel gear 210 meshes with the motor bevel gear 205, and a transmission belt 213 is wound around the upper transmission wheel 209 and the lower transmission wheel 211.

[0035] As Figure 3 、 Figure 4 As shown in the figure, a lower connecting rod 207 is rotatably installed on the moving frame 201. An upper connecting rod 206 is rotatably installed on the lower connecting rod 207. The upper connecting rod 206 is rotatably installed with the welding frame 109, and the welding frame 109 is slidably installed with the moving frame 201.

[0036] The moving motor 204 drives the motor bevel gear 205 to rotate, thereby driving the docking bevel gear 210, the gear shaft 208 and the upper transmission wheel 209 to rotate. Through the transmission belt 213, drive the lower transmission wheel 211, the walking shaft 212 and the moving wheel 202 to rotate, thereby driving the moving frame 201 and the welding frame 109 to move. When the stainless steel plate is inserted below the ball 302 and the moving wheel 202, the sliding column 301 slides a short distance along the welding frame 109, the moving wheel 202 is lifted, driving the moving frame 201 to rise, the lower connecting rod 207 rotates relative to the moving frame 201, the upper connecting rod 206 rotates relative to the lower connecting rod 207, and the moving frame 201 rises along the welding frame 109.

[0037] As Figures 5-8As shown, the welding mechanism includes a ball 302 rotatably mounted at the bottom of the sliding column 301. A lower rotating arm 306 is rotatably mounted on the sliding column 301. An upper rotating arm 305 is slidably mounted outside the lower rotating arm 306. An inner spring 307 is provided between the upper rotating arm 305 and the lower rotating arm 306. A welding torch holder 304 is rotatably mounted on the upper rotating arm 305, and a welding torch 303 is fixedly mounted on the welding torch holder 304.

[0038] As Figures 5-8 shown, a rotating frame 308 is fixedly mounted below the welding frame 109. An insertion block 309 is slidably mounted on the rotating frame 308. An upper plate 310 is fixedly mounted on the insertion block 309. An insertion spring 311 is provided between the upper plate 310 and the rotating frame 308.

[0039] As Figures 5-8 shown, a rotating rod 312 is rotatably mounted on the rotating frame 308. A scroll spring 313 is provided between the rotating rod 312 and the rotating frame 308. A pressing rod 314 is slidably mounted on the rotating rod 312. A pressing plate 315 is fixedly mounted on the pressing rod 314. A pressing spring 316 is provided between the pressing plate 315 and the rotating rod 312.

[0040] The insertion spring 311 causes the insertion block 309 to insert into the weld of the stainless steel part. The pressing spring 316 presses the pressing rod 314 against the weld. When the welding frame 109 moves, first, the pressing rod 314 moves along the weld. When the weld turns, it will cause the rotating rod 312 to rotate relative to the rotating frame 308, and the scroll spring 313 is twisted. A turning force is applied to the rotating frame 308 and the welding frame 109 through the scroll spring 313. Subsequently, the insertion block 309 changes the advancing direction of the rotating frame 308 and the welding frame 109. The movement of the moving frame 201 drives the movement of the welding frame 109, and the two stainless steel plates are welded by the welding torch 303.

[0041] When the surface angle of the welded part changes, the sliding column 301 at the corresponding position will be jacked up to different degrees, thereby jacking up the welding torch holder 304 at this position through the lower rotating arm 306 and the upper rotating arm 305 to adjust the angle of the welding torch 303.

[0042] The working principle of a multi-angle stainless steel part welding device disclosed in the present invention is as follows: When in use, two stainless steel plates to be welded are placed on the bottom plate 101 and pushed between the two clamping frames 107. The slopes on the clamping frames 107 push the clamping sliders 106 and the clamping frames 107 to slide outwards, so that the two stainless steel plates to be welded are kept in a butting state and reach between the horizontal parts of the two clamping frames 107. The clamping springs 108 are compressed, and the two stainless steel plates to be welded are clamped and butted by the two clamping frames 107. When the stainless steel plate is inserted under the balls 302 and the moving wheels 202, the sliding column 301 slides a short distance along the welding frame 109, the moving wheels 202 are lifted, driving the moving frame 201 to rise. The lower connecting rod 207 rotates relative to the moving frame 201, and the upper connecting rod 206 rotates relative to the lower connecting rod 207, and the moving frame 201 rises along the welding frame 109. The moving motor 204 drives the motor bevel gear 205 to rotate, thereby driving the butting bevel gear 210, the gear shaft 208 and the upper transmission wheel 209 to rotate. Through the transmission belt 213, the lower transmission wheel 211, the walking shaft 212 and the moving wheels 202 are driven to rotate, thereby driving the moving frame 201 and the welding frame 109 to move. The insertion spring 311 makes the insertion block 309 insert into the weld of the stainless steel part, and the pressing spring 316 presses the pressing rod 314 on the weld. When the welding frame 109 moves, the sliding block 105 slides along the left and right guide rails 104, and the left and right guide rails 104 slide along the front and rear guide rails 103. First, the pressing rod 314 moves along the weld. When the weld turns, the rotating rod 312 rotates relative to the rotating frame 308, and the scroll spring 313 is twisted. A turning force is applied to the rotating frame 308 and the welding frame 109 through the scroll spring 313. Subsequently, the insertion block 309 changes the advancing direction of the rotating frame 308 and the welding frame 109. The movement of the moving frame 201 drives the movement of the welding frame 109, and the two stainless steel plates are welded by the welding torch 303. When the surface angle of the welded part changes, the sliding columns 301 at the corresponding positions will be lifted to different degrees, so that the welding torch seat 304 at this position will be lifted by the lower rotating arm 306 and the upper rotating arm 305 to adjust the angle of the welding torch 303.

[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.
