[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] One of the purposes of the present invention is to provide a stainless steel screw welding device. Refer to Figures 1-8As shown in the figure, it includes a body 100. A rotating table 101 is provided on the surface of the body 100. A driven gear 102 is provided at the bottom of the rotating table 101. A first motor 103 is provided on one side of the driven gear 102. A driving gear 104 is provided at the output end of the first motor 103. The driving gear 104 meshes with the driven gear 102 for rotation. On both sides of the top of the body 100, a first welding torch 105 and a second welding torch 107 are provided. A limiting seat 106 is provided on the surface of the rotating table 101. The limiting seats 106 are arranged in an array on the surface of the rotating table 101. A plurality of grooves are formed on the surface of the rotating table 101. Clamping assemblies 200 are provided in the grooves. When a water stop screw is inserted into the rotating table 101 through the limiting seat 106, it is limited and fixed by the clamping assemblies 200. A rotating assembly 300 is provided inside the rotating table 101. The rotating assembly 300 is used to drive the water stop screw limited and fixed in the clamping assemblies 200 to rotate. A jacking assembly 400 is provided below the clamping assemblies 200. The jacking assembly 400 penetrates into the inside of the clamping assemblies 200. By pressing the jacking assembly 400, the water stop screw clamped and fixed in the clamping assemblies 200 is jacked outwards, so that the water stop piece welded on the surface of the water stop screw is away from the limiting seat 106. A supporting assembly 500 is provided inside the body 100. The supporting assembly 500 is used to jack out and support the jacking assembly 400. The bottom of the water stop piece welded on the surface of the water stop screw is synchronously welded by the first welding torch 105:

[0040] The improvement of this embodiment lies in that: when the water stop screw after surface welding moves to the position of the second welding torch 107, by pushing the wedge block 402, the wedge block 402 drives the moving rod 401 to move in the vertical direction. The clamping ear 404 at the end of the moving rod 401 pushes the water stop screw fixed between the clamping plates 203, so that the water stop screw after surface welding moves upwards. As a result, there is a gap between the water stop screw after surface welding and the surface of the limiting seat 106, enabling the second welding torch 107 to automatically weld the bottom of the water stop screw after surface welding, thus avoiding secondary welding by changing the direction of the screw and improving the welding efficiency.

[0041] When welding the water-stop screw and the water-stop plate, in order to avoid the deviation of the welding angle and affect the water-stop effect, the clamping assembly 200 includes a base 201 arranged in the groove, the inner wall of the base 201 is provided with a column 202, a clamping plate 203 is slidably arranged inside the column 202, an elastic member 204 is provided between the column 202 and the clamping plate 203, a bearing 205 is provided between the base 201 and the groove, and the base 201 rotates on the inner wall of the bearing 205. By inserting the screw from the limit seat 106, the water-stop screw is guided along the inner wall of the limit seat 106 to move to the base 2 01, a guide slope is provided on the top of the splint 203, which enables the waterstop screw to quickly fit the guide slope and move to the inside of the base 201, and the waterstop screw squeezes the outer wall of the splint 203, so that the splint 203 squeezes the elastic part 204 and slides on the inner wall of the column 202. When the pressure on the waterstop screw stops, the splint 203 is squeezed and fixed by the force of the elastic part 204 to ensure that the waterstop screw always remains in a vertical state during the welding process between the waterstop screw and the waterstop plate, avoiding the welding position from being offset, and ensuring the waterstop effect of the waterstop screw.

[0042] During the welding process of the waterstop screw and the waterstop plate, in order to ensure uniform welding and improve welding efficiency, a gear sleeve 206 is clamped on the surface of the base 201, and the gear sleeves 206 are connected by a toothed belt 207. By adjusting the angle of the first welding gun 105, automatic welding is performed on the required welding position. The gear sleeve 206 is driven by the rotating assembly 300 to rotate, so that the waterstop screw fixed inside the clamping assembly 200 rotates at a uniform speed, so that the first welding gun 105 automatically welds the waterstop screw and the waterstop plate, thereby improving welding efficiency.

[0043] Considering that in the process of welding the water-stop screw, in order to keep it rotating at an automatic uniform speed and improve the welding effect, the rotating assembly 300 includes a servo motor 301 arranged inside the rotating table 101, and the output shaft at the end of the servo motor 301 is provided with a screw 302, the thread on the surface of the screw 302 is symmetrical, and the surface of the screw 302 is provided with a moving block 303, the moving block 303 is symmetrical, and the bottom of the moving block 303 is provided with a rotating motor 304, and the end of the rotating motor 304 is provided with a meshing gear 305. When the screw moves to the first welding gun 105, through The output shaft at the end of the servo motor 301 is controlled to drive the screw 302 to rotate, so that the moving block 303 provided on the surface of the screw 302 moves away from each other until the meshing gear 305 provided under the moving block 303 moves to the gear sleeve 206, and the meshing gear 305 is driven to rotate by the output end of the rotating motor 304, so that the meshing gear 305 drives the gear sleeve 206 to rotate at a uniform speed, so that the waterstop screw clamped and fixed between the clamping plates 203 keeps rotating at a uniform speed during the welding process, ensuring the uniformity and consistency of the weld, and being able to ensure the overall strength and stability of the waterstop screw.

[0044] When the fixing of the water-stop screw is completed, control the rotation angle of the rotating table 101 so that the water-stop screw fixed in the clamping assembly 200 rotates to the first welding torch 105 for surface welding. When the welding is completed, the operator needs to take out the water-stop screw with the surface welding completed and reverse its direction for secondary welding, resulting in low welding efficiency. Therefore, the ejection assembly 400 includes a moving rod 401 provided at the bottom of the rotating table 101. The moving rod 401 penetrates the rotating table 101 into the groove. A wedge block 402 is provided at the end of the moving rod 401. A return spring 403 is provided between the moving rod 401 and the wedge block 402. A clamping ear 404 is provided at the top of the moving rod 401. The clamping ear 404 is clamped on the inner wall of the base 201. Push the wedge block 402 to drive the moving rod 401 to move in the vertical direction. The clamping ear 404 ejects the water-stop screw clamped in the clamping assembly 200. Insert the water-stop screw to be welded into the clamping assembly 200 through the limit seat 106. Drive the fixed water-stop screw to rotate through the rotating table 101. When the water-stop screw rotates to the first welding torch 105, control the rotating assembly 300 to drive the gear sleeve 206 to rotate, so that the water-stop screw fixed inside the clamping assembly 200 rotates automatically. Automatically weld the surface of the water-stop screw with the first welding torch 105. When the surface welding of the water-stop screw is completed, the rotating table 101 continues to rotate. When the water-stop screw with the surface welding completed moves to the second welding torch 107, push the wedge block 402, so that the wedge block 402 drives the moving rod 401 to move in the vertical direction. The clamping ear 404 at the end of the moving rod 401 pushes the water-stop screw fixed between the clamping plates 203, so that the water-stop screw with the surface welding completed moves upward, so that there is a gap between the water-stop screw with the surface welding completed and the surface of the limit seat 106, so that the second welding torch 107 can automatically weld the bottom of the water-stop screw with the surface welding completed, thus avoiding the secondary welding of reversing the screw direction and improving the welding efficiency.

[0045] In the process of welding the water-stop screw, in order to automatically push the screw with the surface welding completed away from the clamping assembly 200, facilitate welding the bottom of the water-stop screw, and reduce the labor intensity of the operators, the support assembly 500 includes a gear shaft 501 arranged on the top of the driven gear 102, a rotating connecting rod 502 is arranged at the end of the gear shaft 501, and one-way gears 503 are arranged on both sides of the surface of the rotating connecting rod 502, one of the one-way gears 503 is meshed and rotated with the end of the gear shaft 501, and the other one-way gear 503 is away from the end of the gear shaft 501. A support frame 504 is provided on the top, a rotating rod is provided inside the support frame 504, an eccentric wheel 505 is provided on the surface of the rotating rod, both sides of the rotating rod pass through the support frame 504 and belt shafts 506 are provided at the ends, the belt shafts 506 and the rotating connecting rods 502 are connected by transmission belts 507, a support plate is provided at the end of the eccentric wheel 505, an arc-shaped push rod 508 is provided at the end of the support plate, a compression spring 509 is provided between the arc-shaped push rod 508 and the support plate, a slope plate 510 is provided at the end of the arc-shaped push rod 508 away from the eccentric wheel 505, and the slope plate 510 is pushed to move to lift the wedge block 402, and the wedge block 402 is lifted by the active When the gear 104 drives the driven gear 102 to rotate, the gear ratio of the driving gear 104 to the driven gear 102 is 1:4, the gear shaft 501 meshes and rotates with the driven gear 102, and the gear shaft 501 drives the one-way gear 503 provided on the surface of the rotating connecting rod 502 to mesh and rotate during the rotation process. Only one of the one-way gears 503 provided on both sides of the surface of the rotating connecting rod 502 meshes and rotates with the end of the gear shaft 501. During the rotation of the rotating connecting rod 502, the belt shaft 506 is driven to rotate through the transmission belt 507, so that the eccentric wheel 505 provided on the surface of the rotating rod rotates coaxially, and the gear shaft The gear ratio of the gear at the end of 501 and the one-way gear 503 is 1:2. When the gear shaft 501 rotates one circle, the eccentric wheel 505 rotates half a circle. When the eccentric wheel 505 rotates, the arc-shaped top rod 508 is pushed. The arc-shaped top rod 508 squeezes the compression spring 509 to drive the slope plate 510 to move in the horizontal direction. During the movement, the slope plate 510 automatically pushes the wedge block 402, so that the bottom of the water-stop screw moved to the second welding gun 107 is pushed, which is convenient for the second welding gun 107 to automatically weld its bottom, avoids the flipping operation of the screw welding, and reduces the labor intensity of the operator.

[0046] During specific use, the water-stop screw is inserted into the interior of the rotating table 101 through the second welding torch 107. The water-stop screw moves along the inner wall of the limit seat 106 and guides into the interior of the base 201. The top of the clamping plate 203 is provided with a guiding slope, which enables the water-stop screw to quickly fit and move along the guiding slope into the interior of the base 201. The water-stop screw squeezes the outer wall of the clamping plate 203, causing the clamping plate 203 to squeeze and slide on the inner wall of the column barrel 202 against the elastic member 204. When pressing on the water-stop screw stops, the clamping plate 203 is acted upon by the elastic member 204 to squeeze and fix the side wall of the water-stop screw, ensuring that the water-stop screw remains in a vertical state during the welding process with the water-stop sheet, avoiding the deviation of the welding position. When the screw moves to the first welding torch 105, the output shaft at the end of the servo motor 301 is controlled to drive the lead screw 302 to rotate, causing the moving block 303 provided on the surface of the lead screw 302 to move away from each other until the meshing gear 305 provided below the meshing gear 305 moves to the gear sleeve 206. The output end of the rotating motor 304 drives the meshing gear 305 to rotate, thereby causing the meshing gear 305 to drive the gear sleeve 206 to rotate at a constant speed, enabling the water-stop screw clamped and fixed between the clamping plates 203 to rotate at a constant speed during the welding process, ensuring the uniformity and consistency of the weld seam, and guaranteeing the overall strength and stability of the water-stop screw. When the water-stop screw after surface welding moves to the second welding torch 107, by pushing the wedge block 402, the wedge block 402 drives the moving rod 401 to move in the vertical direction. The clamping ear 404 at the end of the moving rod 401 pushes the water-stop screw fixed between the clamping plates 203, causing the water-stop screw after surface welding to move upward, so that there is a gap between the water-stop screw after surface welding and the surface of the limit seat 106, enabling the second welding torch 107 to automatically weld the bottom of the water-stop screw after surface welding, thus avoiding the need to re-weld the screw by changing its direction and improving the welding efficiency.
