Description

Technical Field

[0001] This invention belongs to the field of stainless steel railing welding technology, specifically a stainless steel railing welding equipment. Background Technology

[0002] With the booming development of the construction industry, stainless steel railings are widely used in staircases, balconies, and landscape fences due to their corrosion resistance and aesthetic appeal. However, currently, most stainless steel railing welding operations still utilize traditional welding equipment.

[0003] In the existing stainless steel railing installation process, cylindrical stainless steel railings are usually welded to the ground first. After the railings are welded and formed, stainless steel balls are welded to the top of them to make the railing lines smoother and softer, avoid the safety hazards that sharp tops may cause, and improve the protection level and quality of the railings. However, in the actual welding process, firstly, the stainless steel ball needs to be placed at the top of the stainless steel railing. This process relies on manual operation by the staff. Due to the lack of positioning, it is difficult to place the stainless steel ball in the center of the top of the railing, which causes it to shift during subsequent welding and affects the welding quality. Secondly, the entire welding process is carried out in two steps: first placing and then spot welding. When using spot welding equipment, the spot welding parameters are difficult to control, which can easily lead to problems such as incomplete welds and uneven weld points. This not only affects the firmness of the connection between the stainless steel ball and the railing and reduces the service life of the railing, but may also cause the stainless steel ball to fall off during subsequent use due to substandard welding quality.

[0004] Therefore, the present invention provides a stainless steel railing welding device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

The feeding box stores stainless steel balls.

[0007] Preferably, a second guide rail is fixedly connected to the upper surface of the fixed platform, a fixed rod is rotatably connected inside the second guide rail, a sliding block is slidably connected to the circumferential surface of the fixed rod, a positioning platform is rotatably connected to the upper surface of the sliding block, a servo motor is provided inside the sliding block, and a triangular chuck is provided on one side of the positioning platform for gripping stainless steel railings.

[0008] Preferably, the welding assembly further includes two fixed guide rails fixed to the upper surface of the fixed platform. Each fixed guide rail has a fixed plate slidably connected inside it. The top ends of the two fixed plates are fixed to the same connecting platform. An auxiliary motor is fixed to the upper surface of the connecting platform. A limit gear is fixed to the output end of the auxiliary motor. A fixed ring is fixed to one side of the connecting platform. A welding head is rotatably connected inside the fixed ring. The limit gear meshes with a toothed ring inside the fixed ring. The welding head is fixed to the inner wall of the toothed ring.

[0009] Preferably, the limiting component includes a plurality of positioning discs fixed to the upper surface of the rotating disk. Each positioning disc has a plurality of rotating grooves on its surface. A connecting cam is rotatably connected in each rotating groove. A fixing post is slidably connected to the middle of the positioning disc. A compression spring is fixed to the bottom end of the fixing post. A plurality of rack plates are fixed to the circumferential surface of the fixing post. Each rack plate meshes with a corresponding connecting cam. An arc plate is fixed to the arc surface of each connecting cam. A fixing disc is also fixed to the upper surface of the fixing post.

[0010] Preferably, a positioning plate is fixedly connected to one end of each of the arc-shaped plates, a suction cup is fixedly connected to the upper surface of the positioning plate, and a connecting hose is fixedly connected to the lower surface of the positioning plate.

[0011] Preferably, the inside of the feeding box is provided with a first horizontal plate and a second horizontal plate, and two auxiliary plates are fixedly connected to one side of the limiting box. Each auxiliary plate has an electric push rod fixedly connected to its upper surface. One of the electric push rods is fixedly connected to the first horizontal plate, and the other electric push rod is fixedly connected to the second horizontal plate. A drop groove is opened on the upper surface of the feeding box.

[0012] Preferably, a micro motor is fixedly connected to the upper surface of the limiting box, a positioning gear is fixedly connected to the output end of the micro motor, a semi-annular groove is opened inside the limiting box, a semi-annular gear is rotatably connected in the semi-annular groove, the semi-annular gear meshes with the positioning gear, and a positioning rod is fixedly connected to the inner wall of the semi-annular gear.

[0013] Preferably, during the welding process of the stainless steel ball and the stainless steel railing, the first guide rail on the upper surface of the machine body is activated first, driving the feeding box to move closer to the rotating disk. After the feeding box is positioned directly above the horizontal rotating disk, it drops the stainless steel ball onto the limiting component on the upper surface of the rotating disk. The limiting component fixes the stainless steel ball, and then the limiting box resets. Next, the adjusting component is activated, i.e., the first motor is started. The first motor drives the first gear, which in turn drives the rotating cam to rotate, thereby causing the entire rotating disk to rotate towards the fixed platform. After rotation, the second motor is activated. The drive gear rotates, which in turn drives the auxiliary gear to rotate. The rotation of the auxiliary gear causes the rotating disk to rotate, so that the limiting steel ball is aligned with the stainless steel railing held in place by the triangular chuck. Driven by the second guide rail, the stainless steel railing comes into contact with the stainless steel ball. Then, the welding assembly is activated to weld the stainless steel ball and the stainless steel railing. After welding is completed, the sliding block is retracted. When the sliding block is retracted to its lowest point, the built-in servo motor of the sliding block is activated, which starts the positioning table to rotate. The rotation of the positioning table causes the stainless steel ball and stainless steel railing assembly to change direction. Then, the triangular chuck is released, completing the welding work.

[0014] Preferably, after the steel ball falls from the feeding box into the fixed plate on the upper surface of the fixed column, the fixed column slides downward under the influence of the stainless steel ball's gravity. During the sliding process, the compression spring is squeezed. The downward movement of the fixed column will drive several rack plates fixed to the circumference of the fixed column to move downward. The downward movement of the rack plates drives the connecting cam in the rotating groove on the surface of the positioning plate to rotate. The rotation of the connecting cam drives the arc plate to move closer to the stainless steel ball, thereby squeezing the stainless steel ball and limiting its movement. During the process of the arc plate abutting against the stainless steel ball, the suction cup at its end will adhere to the stainless steel ball. The positioning plate fixed to the end of the arc plate has a connecting hose fixed to its lower surface. The connecting hose sprays the pressurized water mist in the rotating plate from the suction cup onto the surface of the stainless steel ball.

[0015] Preferably, during the stainless steel ball feeding process, by activating two electric push rods on one side of the limit box, the two electric push rods push each other alternately, first retracting the first horizontal plate, the steel ball falls onto the upper surface of the second horizontal plate, then pushing the first horizontal plate again to isolate a stainless steel ball between the first and second horizontal plates, and then releasing the second horizontal plate so that the stainless steel ball falls onto the surface of the fixed plate. The steel ball is located in the feeding groove. During the feeding process, the micro motor is activated to drive the positioning gear to rotate. The rotating positioning gear drives the semi-ring gear to rotate along the semi-ring groove, driving the positioning rod to stir the steel ball, thus carrying out the feeding work.

[0016] The beneficial effects of this invention are as follows: 1. The stainless steel railing welding equipment of the present invention uses a first guide rail to drive the feeding box close to the rotating disk for feeding, and uses a limiting component to fix the stainless steel ball, ensuring the accuracy and stability of the stainless steel ball's placement. Then, a first motor drives a rotating cam to turn the rotating disk to a fixed platform. Through the coordinated action of a second motor, a rotating gear, and an auxiliary gear, the rotating disk rotates, aligning the stainless steel ball with the stainless steel railing fixed by the triangular chuck, improving the docking accuracy. After welding is completed, when the sliding block retracts to the bottom, the built-in servo motor is activated, driving the positioning platform to rotate, causing the assembled body to change direction, facilitating the release of the triangular chuck. The entire process is highly automated and smooth to operate, which not only improves welding efficiency but also reduces human error, effectively ensuring welding quality, reducing the defect rate, and improving the overall quality of the product.

[0017] 2. The stainless steel railing welding equipment of the present invention utilizes gravity to initiate subsequent limiting actions by causing the fixed column to slide down and compress the spring after the steel ball falls into the fixed plate. This eliminates the need for an additional drive device, saving energy and costs. The rack plate drives the connecting cam to rotate, causing the arc plate to approach and compress the steel ball, achieving effective limiting and ensuring the stability of the steel ball in subsequent processing. At the same time, the suction cup adsorbs the steel ball to enhance the fixing effect, while the connecting hose sprays pressurized water mist from the suction cup onto the surface of the steel ball, which not only cleans the surface of the steel ball and increases the suction force of the suction cup, but also cools it to a certain extent, improving product quality.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, a stainless steel railing welding device has a fixed platform 3 fixedly connected to one side of the machine body 1. A welding assembly is provided on the upper surface of the fixed platform 3. The welding assembly includes a welding head 312 rotatably mounted above the fixed platform 3. An adjustment assembly is provided on the upper surface of the machine body 1. The adjustment assembly includes a first motor 2 fixedly connected to one side of the machine body 1. A first gear 21 is fixedly connected to the output end of the first motor 2. The first gear 21 meshes with a rotating cam 22. A second motor 23 is fixedly connected to one side of the rotating cam 22. A rotating gear 24 is rotated at the output end of the second motor 23. The rotating gear 24 meshes with an auxiliary gear 25. A rotating gear is fixedly connected to the upper surface of the auxiliary gear 25. The upper surface of the rotating disc 26 is fixed with several limiting components, which are used to limit the stainless steel balls. The upper surface of the machine body 1 is provided with a first guide rail 11, and a feeding box 4 is slidably connected inside the first guide rail 11. The feeding box 4 stores stainless steel balls. The upper surface of the fixed platform 3 is also fixed with a second guide rail 31. A fixed rod 32 is rotatably connected inside the second guide rail 31. A sliding block 33 is slidably connected on the circumference of the fixed rod 32. A positioning platform 34 is rotatably connected on the upper surface of the sliding block 33. A servo motor is installed inside the sliding block 33. A triangular chuck 35 is provided on one side of the positioning platform 34. The triangular chuck 35 is used to clamp the stainless steel railing.

[0022] Specifically, in the actual welding process, firstly, the stainless steel ball needs to be placed at the top of the stainless steel railing. This process relies on manual operation by the staff. Due to the lack of positioning, it is difficult to place the stainless steel ball in the center of the top of the railing, which will cause it to shift during subsequent welding and affect the welding quality. Secondly, the entire welding process is carried out in two steps: first placing and then spot welding. When using spot welding equipment, the spot welding parameters are difficult to control, which can easily lead to problems such as incomplete welding and uneven weld points. This not only affects the firmness of the connection between the stainless steel ball and the railing and reduces the service life of the railing, but may also cause the stainless steel ball to fall off during subsequent use due to poor welding quality. Therefore, this invention solves the above problems by setting the above structure. First, during the welding process of the stainless steel ball and the stainless steel railing, the first guide rail 11 on the upper surface of the machine body 1 is started, driving the feeding box 4 to move closer to the rotating disk 26. After the feeding box 4 is directly above the horizontal rotating disk 26, the feeding box 4 drops the stainless steel ball onto the limiting component on the upper surface of the rotating disk 26. The stainless steel ball is fixed by the limiting component. Then the limiting box is reset, and then the adjustment component is started, that is, the first motor 2 is started. The first motor 2 drives the first gear 21, and the first gear 21 drives the rotating cam 22 to rotate, thereby driving the entire rotating disk 26 to rotate towards the fixed platform 3. After the rotating disk 26 has rotated, the second adjustment component is started. Motor 23 drives rotating gear 24 to rotate, rotating gear 24 drives auxiliary gear 25 to rotate, and the rotation of auxiliary gear 25 drives rotating disk 26 to rotate, so that the limiting steel ball is aligned with the stainless steel railing held by triangular chuck 35. The stainless steel railing abuts against the stainless steel ball under the drive of second guide rail 31. Then the welding assembly is started to weld the stainless steel ball and stainless steel railing. After welding is completed, sliding block 33 is retracted. When sliding block 33 is retracted to the bottom, the built-in servo motor of sliding block 33 is started to start positioning table 34 to rotate. The rotation of positioning table 34 causes the stainless steel ball and stainless steel railing assembly to change direction. Then the triangular chuck 35 is released, and the welding work is completed. During the welding preparation stage, the material feeding box 4 is driven by the first guide rail 11 to approach the rotating disk 26 for feeding, and the stainless steel ball is fixed by the limiting component to ensure the accuracy and stability of the stainless steel ball's placement. Then, the first motor 2 drives the rotating cam 22 to turn the rotating disk 26 to the fixed platform 3. Then, through the coordinated action of the second motor 23, the rotating gear 24 and the auxiliary gear 25, the rotating disk 26 is rotated, so that the stainless steel ball is aligned with the stainless steel railing fixed by the triangular chuck 35, which improves the docking accuracy. After welding is completed, when the sliding block 33 retracts to the bottom, the built-in servo motor is activated to drive the positioning platform 34 to rotate, so that the joint body changes direction, which facilitates the release of the triangular chuck 35. The whole process is highly automated and smooth to operate, which not only improves welding efficiency, but also reduces human operation error, effectively ensures welding quality, reduces the defect rate, and improves the overall quality of the product.

[0023] Example 2: Figures 1 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the welding assembly further includes two fixed guide rails 36 fixedly connected to the upper surface of the fixed platform 3, each fixed guide rail 36 having a fixed plate 37 slidably connected inside, the top ends of the two fixed plates 37 being fixedly connected to the same connecting platform 38, the upper surface of the connecting platform 38 being fixedly connected to an auxiliary motor 39, the output end of the auxiliary motor 39 being fixedly connected to a limit gear 310, a fixed ring 311 being fixedly connected to one side of the connecting platform 38, a welding head 312 being rotatably connected inside the fixed ring 311, the limit gear 310 meshing with the gear ring inside the fixed ring 311, and the welding head 312 being fixedly connected to the inner wall of the gear ring; the limiting assembly includes a plurality of positioning discs 27 fixedly connected to the upper surface of the rotating disk 26. Each positioning disk 27 has several rotating grooves 28 on its surface. A connecting cam 213 is rotatably connected in each rotating groove 28. A fixing post 210 is slidably connected to the middle of the positioning disk 27. A compression spring 29 is fixed to the bottom end of the fixing post 210. Several rack plates 212 are fixed to the circumferential surface of the fixing post 210. Each rack plate 212 meshes with the corresponding connecting cam 213. An arc plate 214 is fixed to the arc surface of each connecting cam 213. A fixing disk 211 is also fixed to the upper surface of the fixing post 210. A positioning plate 215 is fixed to one end of each arc plate 214. A suction cup 216 is fixed to the upper surface of the positioning plate 215. A connecting hose 217 is fixed to the lower surface of the positioning plate 215.

[0024] Specifically, after the steel ball falls from the feeding box 4 into the fixed plate 211 on the upper surface of the fixed column 210, the fixed column 210 slides downward under the influence of the weight of the stainless steel ball. During the sliding process, the compression spring 29 is squeezed. The downward movement of the fixed column 210 will drive several rack plates 212 fixed to the circumferential surface of the fixed column 210 to move downward. The downward movement of the rack plates 212 drives the connecting cam 213 in the rotating groove 28 on the surface of the positioning plate 27 to rotate. The rotation of the connecting cam 213 drives the arc plate 214 to move closer to the stainless steel ball, thereby squeezing the stainless steel ball and limiting the stainless steel ball. During the process of the arc plate 214 abutting against the stainless steel ball, the suction cup 216 at its end will be attracted to the stainless steel ball. The positioning plate 215 fixed to the end of the arc plate 214 has a connecting hose 217 fixed to its lower surface. The connecting hose 217 sprays the pressurized water mist in the rotating plate 26 from the suction cup 216 to the surface of the stainless steel ball. After the steel ball falls into the fixed plate 211, the fixed column 210 slides down due to gravity and compresses the compression spring 29, using gravity to initiate the subsequent limiting action. No additional drive device is required, saving energy and cost. The rack plate 212 drives the connecting cam 213 to rotate, causing the arc plate 214 to approach and squeeze the steel ball, achieving effective limiting and ensuring the stability of the steel ball in subsequent processing. At the same time, the suction cup 216 adsorbs the steel ball to enhance the fixing effect, while the connecting hose 217 sprays pressurized water mist from the suction cup 216 onto the surface of the steel ball, which can clean the surface of the steel ball, increase the adsorption force of the suction cup 216, and also play a certain role in cooling, improving product quality.

[0025] like Figure 8 As shown, in this embodiment, the inside of the feeding box 4 is provided with a first horizontal plate 49 and a second horizontal plate 410. Two auxiliary plates 47 are fixedly connected to one side of the limiting box. Each auxiliary plate 47 has an electric push rod 48 fixedly connected to its upper surface. One electric push rod 48 is fixedly connected to the first horizontal plate 49, and the other electric push rod 48 is fixedly connected to the second horizontal plate 410. A drop groove 42 is opened on the upper surface of the feeding box 4. A micro motor 41 is fixedly connected to the upper surface of the limiting box. A positioning gear 43 is fixedly connected to the output end of the micro motor 41. A semi-annular groove 44 is opened inside the limiting box. A semi-annular gear 45 is rotatably connected in the semi-annular groove 44. The semi-annular gear 45 meshes with the positioning gear 43. A positioning rod 46 is fixedly connected to the inner wall of the semi-annular gear 45.

[0026] Specifically, during the stainless steel ball feeding process, by activating two electric push rods 48 on one side of the limit box, the two electric push rods 48 push each other in an alternating manner, firstly retracting the first horizontal plate 49, the steel ball falls onto the upper surface of the second horizontal plate 410, then pushing the first horizontal plate 49 again, isolating a stainless steel ball between the first horizontal plate 49 and the second horizontal plate 410, and then releasing the second horizontal plate 410, so that the stainless steel ball falls onto the surface of the fixed plate 211, the steel ball is located in the feeding groove. During the feeding process, the micro motor 41 is activated to drive the positioning gear 43 to rotate, the rotating positioning gear 43 drives the semi-ring gear 45 to rotate along the semi-ring groove 44, driving the positioning rod 46 to stir the steel ball, and carry out the feeding work; By using two interlocking electric push rods 48 during loading, the first horizontal plate 49 is retracted, then the isolation is pushed, and finally the second horizontal plate 410 is released. This controls the process so that only one stainless steel ball falls onto the surface of the fixed plate 211 at a time, achieving orderly loading of single balls and avoiding confusion or jamming caused by multiple balls falling at the same time. This ensures the accuracy and stability of loading. During unloading, the micro motor 41 drives the positioning gear 43 to rotate, which in turn causes the positioning rod 46 to stir the steel balls, effectively preventing the steel balls from accumulating and blocking in the unloading trough, ensuring smooth unloading, and improving the continuity and efficiency of the overall production process.

[0027] The working principle is as follows: First, during the welding of the stainless steel ball and the stainless steel railing, the first guide rail 11 on the upper surface of the machine body 1 is activated, driving the feeding box 4 to approach the rotating disk 26. After the feeding box 4 is directly above the horizontal rotating disk 26, it drops the stainless steel ball onto the limiting component on the upper surface of the rotating disk 26. The limiting component fixes the stainless steel ball, and then the limiting box resets. Next, the adjusting component is activated, i.e., the first motor 2 is started. The first motor 2 drives the first gear 21, which in turn drives the rotating cam 22 to rotate, thereby causing the entire rotating disk 26 to rotate towards the fixed platform 3. After the rotating disk 26 has rotated, the second motor 23 is activated. The machine 23 drives the rotating gear 24 to rotate, the rotating gear 24 drives the auxiliary gear 25 to rotate, the rotation of the auxiliary gear 25 drives the rotating disk 26 to rotate, so that the limiting steel ball is aligned with the stainless steel railing held by the triangular chuck 35. The stainless steel railing abuts against the stainless steel ball under the drive of the second guide rail 31. Then the welding assembly is started to weld the stainless steel ball and the stainless steel railing. After the welding is completed, the sliding block 33 is retracted. When the sliding block 33 is retracted to the bottom, the built-in servo motor of the sliding block 33 is started, and the positioning table 34 is started to rotate. The rotation of the positioning table 34 causes the stainless steel ball and the stainless steel railing to change direction. Then the triangular chuck 35 is released, and the welding work is completed. During the welding preparation stage, the material feeding box 4 is driven by the first guide rail 11 to approach the rotating disk 26 for feeding, and the stainless steel ball is fixed by the limiting component to ensure the accuracy and stability of the stainless steel ball's placement. Then, the first motor 2 drives the rotating cam 22 to turn the rotating disk 26 to the fixed platform 3. Then, through the coordinated action of the second motor 23, the rotating gear 24 and the auxiliary gear 25, the rotating disk 26 is rotated, so that the stainless steel ball is aligned with the stainless steel railing fixed by the triangular chuck 35, which improves the docking accuracy. After welding is completed, when the sliding block 33 retracts to the bottom, the built-in servo motor is activated to drive the positioning platform 34 to rotate, so that the combined body changes direction, which facilitates the release of the triangular chuck 35. The whole process is highly automated and smooth to operate, which not only improves welding efficiency, but also reduces human operation error, effectively ensures welding quality, reduces the defect rate, and improves the overall quality of the product. After the steel ball falls from the feeding box 4 into the fixed plate 211 on the upper surface of the fixed column 210, the fixed column 210 slides downward under the influence of the weight of the stainless steel ball. During the sliding process, the compression spring 29 is squeezed. The downward movement of the fixed column 210 will drive several rack plates 212 fixed to the circumference of the fixed column 210 to move downward. The downward movement of the rack plates 212 drives the connecting cam 213 in the rotating groove 28 on the surface of the positioning plate 27 to rotate. The rotation of the connecting cam 213 drives the arc plate 214 to move closer to the stainless steel ball, thereby squeezing the stainless steel ball and limiting the stainless steel ball. During the process of the arc plate 214 abutting against the stainless steel ball, the suction cup 216 at its end will be attracted to the stainless steel ball. The positioning plate 215 fixed to the end of the arc plate 214 has a connecting hose 217 fixed to its lower surface. The connecting hose 217 sprays the pressurized water mist in the rotating plate 26 from the suction cup 216 to the surface of the stainless steel ball. After the steel ball falls into the fixed plate 211, the fixed column 210 slides down due to gravity and compresses the compression spring 29, using gravity to initiate the subsequent limiting action. No additional drive device is required, saving energy and cost. The rack plate 212 drives the connecting cam 213 to rotate, causing the arc plate 214 to approach and compress the steel ball, achieving effective limiting and ensuring the stability of the steel ball in subsequent processing. At the same time, the suction cup 216 adsorbs the steel ball to enhance the fixing effect, while the connecting hose 217 sprays pressurized water mist from the suction cup 216 onto the surface of the steel ball, which can clean the surface of the steel ball, increase the adsorption force of the suction cup 216, and also play a certain role in cooling, improving product quality. In addition, during the stainless steel ball feeding process, by activating the two electric push rods 48 on one side of the limit box, the two electric push rods 48 push each other in an alternating manner, firstly retracting the first horizontal plate 49, the steel ball falls onto the upper surface of the second horizontal plate 410, then pushing the first horizontal plate 49, isolating a stainless steel ball between the first horizontal plate 49 and the second horizontal plate 410, and then releasing the second horizontal plate 410, so that the stainless steel ball falls onto the surface of the fixed plate 211. The steel ball is located in the feeding groove. During the feeding process, the micro motor 41 is activated to drive the positioning gear 43 to rotate. The rotating positioning gear 43 drives the semi-ring gear 45 to rotate along the semi-ring groove 44, driving the positioning rod 46 to stir the steel ball and carry out the feeding work. By using two interlocking electric push rods 48 during loading, the first horizontal plate 49 is retracted, then the isolation is pushed, and finally the second horizontal plate 410 is released. This controls the process so that only one stainless steel ball falls onto the surface of the fixed plate 211 at a time, achieving orderly loading of single balls and avoiding confusion or jamming caused by multiple balls falling at the same time. This ensures the accuracy and stability of loading. During unloading, the micro motor 41 drives the positioning gear 43 to rotate, which in turn causes the positioning rod 46 to stir the steel balls, effectively preventing the steel balls from accumulating and blocking in the unloading trough, ensuring smooth unloading, and improving the continuity and efficiency of the overall production process.
