Technical Field

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

[0002] Stainless steel is a common metal material in modern applications. It is widely used in many fields because of its excellent rust and corrosion resistance. According to the requirements of different fields, the base material can be adjusted to change the material properties. In the actual application process, due to different needs, the material needs to be cut and welded. For special-shaped materials, even manual welding cannot guarantee the quality of welding. Therefore, a device that meets multi-angle welding is needed to ensure the welding quality. The multi-angle stainless steel plate welding device in the prior art cannot automatically move and weld along the weld. Each processing needs to be independently programmed, and automatic welding cannot be achieved, and the degree of automation is poor. 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 welding device, comprising a main body mechanism for clamping the stainless steel, the main body mechanism comprising a bottom plate, a welding mechanism for welding the stainless steel and a moving mechanism for driving the welding mechanism to move are arranged on the main body mechanism, the moving mechanism comprises a moving frame, and the welding mechanism comprises a plurality of sliding columns; The main body mechanism comprises a welding frame, and a plurality of sliding posts are slidably mounted on the welding frame.

[0004] Furthermore, the main body structure also includes a plurality of vertical frames fixedly mounted on the bottom plate, two front and rear guide rails are fixedly mounted on the vertical frames, left and right guide rails are slidably mounted on the front and rear guide rails, sliding blocks are slidably mounted on the left and right guide rails, and the welding frame is rotatably mounted on the sliding blocks.

[0005] Furthermore, two clamping slide blocks are slidably mounted on the bottom plate, a clamping frame is fixedly mounted on the clamping slide block, and a clamping spring is arranged between the clamping slide block and the bottom plate.

[0006] When in use, two stainless steel plates to be welded are placed on the bottom plate and pushed between the two clamping frames. The clamping slider and the clamping frame are pushed to slide outward through the slope on the clamping frame, so that the two stainless steel plates to be welded remain in a butt-jointed state and reach 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 butt-jointed by the two clamping frames.

[0007] 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.

[0008] Furthermore, the mobile mechanism includes a walking shaft rotatably installed under the mobile frame, a lower transmission wheel and a moving wheel are fixedly installed on the walking shaft, the moving wheel rolls on the bottom plate, a motor frame is fixedly installed on the mobile frame, a mobile motor is fixedly installed on the motor frame, a motor bevel gear is fixedly installed on the motor shaft of the mobile motor, a gear shaft is rotatably installed on the mobile frame, an upper transmission wheel and a docking bevel gear are fixedly installed on the gear shaft, the docking bevel gear is meshed with the motor bevel gear, and a transmission belt is wrapped around the upper transmission wheel and the lower transmission wheel.

[0009] Furthermore, a lower connecting rod is rotatably mounted on the movable frame, an upper connecting rod is rotatably mounted on the lower connecting rod, the upper connecting rod is rotatably mounted on the welding frame, and the welding frame is slidably mounted on the movable frame.

[0010] The mobile motor drives the motor bevel gear to rotate, thereby driving the docking bevel gear, gear shaft and upper transmission wheel to rotate, and driving the lower transmission wheel, walking shaft and mobile wheel to rotate through the transmission belt, thereby driving the mobile frame and welding frame to move. When the stainless steel plate is inserted under the ball bearing and the mobile wheel, the sliding column slides a short distance along the welding frame, the mobile wheel is lifted up, driving the mobile frame to rise, the lower connecting rod rotates relative to the mobile frame, the upper connecting rod rotates relative to the lower connecting rod, and the mobile frame rises along the welding frame.

[0011] Furthermore, the welding mechanism includes a ball bearing 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 arranged between the upper rotating arm and the lower rotating arm, a welding gun seat is rotatably mounted on the upper rotating arm, and a welding gun is fixedly mounted on the welding gun seat.

[0012] Furthermore, a rotating frame is fixedly installed below the welding frame, an insertion block is slidably installed on the rotating frame, an upper plate is fixedly installed on the insertion block, and an insertion spring is arranged between the upper plate and the rotating frame.

[0014] The insertion spring allows the insertion block to be inserted into the weld of the stainless steel part, and the clamping spring presses the clamping rod on the weld. When the welding frame moves, the clamping rod first moves along the weld. When the weld turns, the rotating rod rotates relative to the rotating frame, and the volute spring is twisted. A steering force is applied to the rotating frame and the welding frame through the volute spring, and then the insertion block changes the forward direction of the rotating frame and the welding frame. The movement of the moving frame drives the welding frame to move, and the two stainless steel plates are welded by the welding gun.

[0015] When the surface angle of the weldment changes, the slide column at the corresponding position will be lifted to different degrees, so that the welding gun seat will be lifted at that position through the lower rotating arm and the upper rotating arm to adjust the angle of the welding gun.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) the main body mechanism provided in the present invention can dock and clamp the stainless steel plates to be welded, and guide them through the front and rear guide rails and the left and right guide rails, thereby ensuring the stability of the welding process and improving the welding quality; (2) the welding mechanism provided in the present invention enables the movable frame and the welding gun to move along the weld under the action of the clamping rod and the insertion block, thereby realizing fully automatic multi-angle welding; (3) the welding mechanism provided in the present invention moves under the drive of the movable mechanism. When the surface angle of the weldment changes, the sliding column in the corresponding position will be lifted to different degrees, thereby lifting the welding gun seat in that position through the lower rotating arm and the upper rotating arm, adjusting the angle of the welding gun, and facilitating welding.

[0030] 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 clamping slider 106 and the clamping frame 107 are pushed to slide outward through the slope on the clamping frame 107, so that the two stainless steel plates to be welded remain in a docking state and reach between the horizontal parts of the two clamping frames 107. The clamping spring 108 is compressed, and the two stainless steel plates to be welded are clamped and docked through the two clamping frames 107.

[0031] 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 .

[0032] like Figure 3 , Figure 4 As shown, 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 is meshed with the motor bevel gear 205, and a transmission belt 213 is wrapped around the upper transmission wheel 209 and the lower transmission wheel 211.

[0034] The mobile 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, and drives the lower transmission wheel 211, the walking shaft 212 and the mobile wheel 202 to rotate through the transmission belt 213, thereby driving the mobile frame 201 and the welding frame 109 to move. When the stainless steel plate is inserted under the ball bearing 302 and the mobile wheel 202, the sliding column 301 slides a short distance along the welding frame 109, and the mobile wheel 202 is lifted up, driving the mobile frame 201 to rise, the lower connecting rod 207 rotates relative to the mobile frame 201, the upper connecting rod 206 rotates relative to the lower connecting rod 207, and the mobile frame 201 rises along the welding frame 109.

[0035] like Figure 5-Figure 8As shown, the welding mechanism includes a ball 302 rotatably mounted on the bottom of a slide column 301, a lower rotating arm 306 is rotatably mounted on the slide 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 gun seat 304 is rotatably mounted on the upper rotating arm 305, and a welding gun 303 is fixedly mounted on the welding gun seat 304.

[0038] The insertion spring 311 allows the insertion block 309 to be inserted into the weld of the stainless steel part, and the clamping spring 316 presses the clamping rod 314 on the weld. When the welding frame 109 moves, the clamping rod 314 first moves along the weld. When the weld turns, the rotating rod 312 rotates relative to the rotating frame 308, and the spiral spring 313 is twisted.

[0040] The working principle of a multi-angle stainless steel welding device disclosed in the present invention is as follows: when in use, two stainless steel plates to be welded are placed on a bottom plate 101 and pushed between two clamping frames 107, and the clamping slider 106 and the clamping frame 107 are pushed to slide outward by the slope on the clamping frame 107, so that the two stainless steel plates to be welded are kept in a docking state and reach between the horizontal parts of the two clamping frames 107, and the clamping spring 108 is compressed, and the two stainless steel plates to be welded are clamped and docked by the two clamping frames 107. When the stainless steel plate is inserted under the ball bearing 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 up, 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.

When the welding frame 1 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 spiral spring 313 is twisted. A steering force is applied to the rotating frame 308 and the welding frame 109 through the spiral spring 313, and then the insertion block 309 changes the forward direction of the rotating frame 308 and the welding frame 109. The welding frame 109 is moved by the movement of the moving frame 201, and the two stainless steel plates are welded by the welding gun 303. When the angle of the weld surface changes, the sliding column 301 in the corresponding direction will be lifted to different degrees, so that the welding gun seat 304 in this direction will be lifted through the lower rotating arm 306 and the upper rotating arm 305 to adjust the angle of the welding gun 303.
