Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] One of the purposes of the present invention is to provide a stainless steel screw welding device, referring to Figure 1-Figure 8 As shown, 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, and a driving gear 104 is provided at the output end of the first motor 103. The driving gear 104 meshes and rotates with the driven gear 102. A first welding gun 105 and a second welding gun 107 are provided on both sides of the top of the body 100, and a limit seat 106 is provided on the surface of the rotating table 101. The limit seats 106 are arranged in an array on the surface of the rotating table 101. A plurality of grooves are opened on the surface of the rotating table 101, and a clamping assembly 200 is provided in each groove. When the water stop screw is inserted into the interior of the rotating table 101 through the limit seat 106, the clamping assembly 200 is limited and fixed to it, a rotating assembly 300 is provided inside the rotating table 101, and the rotating assembly 300 is used to drive the water-stop screw fixed in the clamping assembly 200 to rotate, and an ejection assembly 400 is provided below the clamping assembly 200, and the ejection assembly 400 penetrates into the inside of the clamping assembly 200, and the ejection assembly 400 is pressed to eject the water-stop screw clamped and fixed in the clamping assembly 200 to the outside, so that the water-stop sheet welded on the surface of the water-stop screw is away from the limiting seat 106, and a supporting assembly 500 is provided inside the machine body 100, and the supporting assembly 500 is used to eject and support the ejection assembly 400, and the bottom of the water-stop sheet welded on the surface of the water-stop screw is synchronously welded by the first welding gun 105: The improvement of this embodiment is that when the waterstop screw after surface welding is completed moves to the second welding gun 107, the wedge block 402 is pushed to drive the moving rod 401 to move in the vertical direction, and the snap-in ear 404 at the end of the moving rod 401 pushes the waterstop screw fixed between the clamping plates 203, so that the waterstop screw after surface welding is completed moves upward, so that there is a gap between the waterstop screw after surface welding and the surface of the limit seat 106, so that the second welding gun 107 can automatically weld the bottom of the waterstop screw after surface welding, thereby avoiding secondary welding of the screw when the direction is changed, and improving welding efficiency.

[0023] 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.

[0024] 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.

[0025] 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, the rotating motor 304 is provided with a meshing gear 305. At the same time, the output shaft at the end of the servo motor 301 is controlled to drive the screw rod 302 to rotate, so that the moving block 303 provided on the surface of the screw rod 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 rotating motor 304 rotates at a uniform speed, so that the water-stop 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 water-stop screw.

[0026] When the water-stop screw is fixed, the rotating angle of the rotating table 101 is controlled so that the water-stop screw fixed in the clamping assembly 200 is rotated to the first welding gun 105 for surface welding. When the welding is completed, the operator needs to take out the water-stop screw with surface welding and turn the direction to perform secondary welding, which leads to low welding efficiency. Therefore, the ejection assembly 400 includes a moving rod 401 provided at the bottom of the rotating table 101, and the moving rod 401 passes through the rotating table 101 to the inside of 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, and the clamping ear 404 is clamped on the inner wall of the base 201, pushing the wedge block 402 to drive the moving rod 401 to move in the vertical direction, and the clamping ear 404 pushes out the water stop screw clamped in the clamping assembly 200, and the water stop screw to be welded is inserted into the clamping assembly 200 through the limit seat 106, and the water stop screw is rotated. The table 101 drives the fixed water-stop screw to rotate. When the water-stop screw rotates to the first welding gun 105, the gear sleeve 206 is driven to rotate by controlling the rotating component 300, so that the water-stop screw fixed inside the clamping component 200 rotates, and the surface of the water-stop screw is automatically welded by the first welding gun 105. When the surface welding of the water-stop screw is completed, the rotating table 101 continues to rotate. When the water-stop screw after surface welding moves to the second welding gun 107, the wedge block 402 is pushed to make the wedge block 402 drive the moving rod 401 to move in the vertical direction. The snap-on 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 surface welding is moved upward, so that there is a gap between the water-stop screw with surface welding and the surface of the limit seat 106, so that the second welding gun 107 can automatically weld the bottom of the water-stop screw with surface welding, thereby avoiding secondary welding of the screw direction change and improving welding efficiency.

[0027] 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.

[0028] When in use, the water-stop screw is inserted into the rotating table 101 through the second welding gun 107, and the water-stop screw is guided along the inner wall of the limit seat 106 to the inside of the base 201. A guiding slope is provided on the top of the splint 203, which can enable the water-stop screw to quickly fit the guiding slope and move to the inside of the base 201. The water-stop screw squeezes the outer wall of the splint 203, so that the splint 203 squeezes the elastic member 204 and slides on the inner wall of the column tube 202. When the water-stop screw is stopped from being pressed, the splint 203 is squeezed and fixed by the force of the elastic member 204 to ensure that the water-stop screw and the water-stop plate are welded. The water-stop screw always remains in a vertical state to avoid welding position deviation. When the screw moves to the first welding gun 105, 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 below the meshing gear 305 is engaged. 5 moves to the gear sleeve 206, and drives the meshing gear 305 to rotate by the output end of the rotating motor 304, so that the rotating motor 304 rotates at a uniform speed, so that the water-stop 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 ensuring the overall strength and stability of the water-stop screw.
