Description

Technical Field

[0001] The present invention relates to the field of processing inclined columns of industrial railings, and particularly to an automatic welding equipment for inclined columns of industrial railings. Background Art

[0002] In the manufacturing process of inclined columns of industrial railings, the previous practice was to rely on manual labor to complete key welding. Specifically, three prefabricated perforated spheres, three steel round tubes with specific interface treatments, and an inclined steel plate were assembled and welded into an integral structure in sequence. However, this manual welding method has obvious limitations in terms of production efficiency, working conditions, and product quality.

[0003] First of all, the production efficiency of manual welding is low, restricting the improvement of production capacity. Moreover, the working environment of manual welding is often unsatisfactory. Workers need to frequently manually pick and place components during welding, which is not only cumbersome but also reduces work efficiency. More seriously, the welding fumes generated during welding pose a potential threat to the physical health of workers, and long-term exposure is likely to cause respiratory diseases and other health problems.

[0004] Therefore, in order to improve production efficiency and working environment, we propose an automatic welding equipment for inclined columns of industrial railings. Summary of the Invention

Workers need to frequently manually pick and place components during welding, which is not only cumbersome but also reduces work efficiency. More seriously, the welding fumes generated during welding pose a potential threat to the physical health of workers, and long-term exposure is likely to cause respiratory diseases and other health problems.

[0006] To achieve the purpose of the present invention, the technical solution adopted by the present invention is as follows: Design an automatic welding equipment for inclined columns of industrial railings, including a device bottom shell. Both the front and rear ends of the top of the device bottom shell are provided with first square holes. Inside the first square holes, fixing plates are installed. On the top of the fixing plates, component fixing assemblies are arranged. A circumferential welding assembly is arranged outside the device bottom shell. One side of the top of the device bottom shell is fixed with a support rod, and the top of the support rod is fixed with a device top plate. Both the front and rear ends of the bottom of the device top plate are installed with a plurality of first telescopic cylinders, and the bottom of the plurality of first telescopic cylinders is installed with upper rollers.

[0007] Preferably, the component fixing assembly includes a first motor, a second motor, steel balls, second telescopic cylinders, mounting brackets, and V-block clamping toolings.

[0008] Preferably, the first motor and the second motor are respectively installed on both sides of the top of the fixed plate, and a plurality of steel round tubes are arranged between the first motor and the second motor, and a V-block clamping tooling is clamped outside one of the steel round tubes.

[0009] Preferably, steel balls are arranged between the plurality of steel round tubes, the second telescopic cylinder body passes through the inside of the steel balls, and the other end of the second telescopic cylinder body passes through an opening formed on the surface of the fixed plate and is installed in a mounting frame at the bottom of the fixed plate.

[0010] Preferably, the circumferential welding assembly includes an annular electric slide rail, an electric slider, a welding robot, a circular groove, a driving motor, and a part placement frame.

[0011] Preferably, the annular electric slide rail is installed outside the bottom shell of the device, one end of the annular electric slide rail is slidably connected with an electric slider, and a welding robot is installed on the top of the electric slider.

[0012] Preferably, a circular groove is formed on the side surface of the electric slider, a driving motor is installed inside the circular groove, and one end of the driving motor extending out of the circular groove is connected with a part placement frame.

[0013] Preferably, a second square hole is formed on the top of the bottom shell of the device, and a filter net body is installed inside the second square hole.

[0014] Preferably, arc-shaped holes are formed on both sides of the bottom of the bottom shell of the device, activated carbon filters are installed inside the arc-shaped holes, one ends of two connecting rods are fixed on both sides inside the bottom shell of the device, and a double-shaft motor is installed between the two connecting rods, and the upper ends of the two ends of the double-shaft motor are respectively connected with a first rotating rod and a second rotating rod.

[0015] Preferably, a suction fan blade is installed on the top of the first rotating rod, and a centrifugal impeller is installed on the bottom of the second rotating rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The present invention adopts a part fixing assembly, which ensures the accuracy of the position and posture of each part of the ball joint railing during the welding process, helps to achieve stable welding quality, and improves the consistency and reliability of the product.

[0018] 2. By combining a ring-shaped electric slide rail, an electric slider, and a welding robot, and introducing automated welding equipment such as a welding robot, the present invention realizes the automated production and assembly line operation of ball joint railings. This significantly reduces the manual operation links, shortens the production cycle, and improves production efficiency. Compared with traditional manual welding methods, the automated welding solution can complete welding tasks more quickly, meeting the large market demand for ball joint railings. At the same time, by using a ring-shaped electric slide rail to drive the electric slider to move in a circle, the welding robot can move in a circle along the slide rail, thus performing all-round operations around the device. The robot can directly move to any position or angle at the top of the device to perform precise welding operations on the corresponding parts, and can meet the welding requirements of various parts of the device without setting up multiple welding robots or complex transmission mechanisms, thereby saving costs.

[0019] 3. Through the electric slider, drive motor, and part placement frame of the present invention, a large number of welding parts are neatly placed in the part placement frame, optimizing the storage and retrieval process of parts. Moreover, the part placement frame is connected to the electric slider through the drive motor, so that during the process of adjusting the position of the welding robot to weld different parts, the part placement frame can move synchronously, ensuring that the welding robot can quickly grab the required parts at any required position, greatly improving the flexibility and efficiency of production. The robot does not need to wait for parts to be manually delivered to the designated position. Not only that, when the parts in the part placement frame need to be replaced or replenished, the part placement frame can be driven by the drive motor to flip, thus pouring out the internal parts, which not only saves manpower but also shortens the part replacement time, further improving the overall production efficiency.

[0020] 4. By integrating a suction fan blade and a centrifugal impeller driven by a dual-axis motor, the present invention realizes the efficient capture of welding fumes generated during the welding process. The welding fumes are first sucked into the bottom shell of the device and then pumped to the activated carbon filter screen through the centrifugal impeller for filtration to ensure the removal of harmful substances in the welding fumes. Combining the welding fume treatment mechanism with the welding device not only saves space but also eliminates the need to additionally set up welding fume treatment equipment.

Detailed implementation manner

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0027] Embodiment 1: An automatic welding equipment for inclined columns of industrial railings, see Figures 1 to 4, including the device bottom shell 1. At the front and rear ends of the top of the device bottom shell 1, there are first square holes 2. Inside the first square holes 2, there are fixed plates 201 installed. On the top of the fixed plates 201, there are component fixing assemblies. Outside the device bottom shell 1, there is a circumferential welding assembly. On one side of the top of the device bottom shell 1, there is a support rod 101 fixed. On the top of the support rod 101, there is a device top plate 102 fixed. At the front and rear ends of the bottom of the device top plate 102, there are multiple first telescopic cylinders 103 installed. At the bottom of the multiple first telescopic cylinders 103, there are upper rollers 104 installed. Workers first place the product components to be welded, such as steel round tubes, perforated spheres, etc., into the component fixing tooling on the welding platform according to the design drawings and process requirements. Once the components are placed in the fixing tooling, the V-block clamping cylinder is immediately started to clamp the inclined-section steel pipe to ensure that it will not move or shake during the welding process. At the same time, the cylinder on the right side is started to push and press each component to further strengthen the stability of the components in the tooling. Next, the operator turns on the power of the annular electric slide rail 205, and the annular electric slide rail 205 starts to work, driving the electric slider 202 to move in a circular motion along the slide rail. The electric slider 202 is connected to the welding robot 203, so the welding robot 203 also moves in a circular motion along the slide rail accordingly, enabling the welding robot 203 to perform all-round operations around the device and directly move to any position or angle at the top of the device. After the welding robot 203 moves to the appropriate position, the first telescopic cylinder 103 is started to press down the upper roller 104. The upper roller 104 cooperates with the lower roller in the component fixing tooling to tightly press the components to ensure that the components will not be displaced due to external forces during the welding process. Subsequently, the rotary pressing cylinder returns to its position to prepare for the next welding operation. After all preparations are completed, the welding robot 203 starts to perform spot welding operations. The robot controls the welding torch to perform spot welding on the components. After the spot welding is completed, the second telescopic cylinder 211 that fixes the steel ball 212 on the welding platform retracts to make room for the rotation of the product. Then, the motor is started to drive the product to rotate. While the product is rotating, the welding robot 203 continues to perform full welding operations. After the full welding is completed, the pressing tooling returns to its position to release the components. At this time, the worker can manually complete the blanking operation, take the welded product off the welding platform, and prepare the feeding for the next production.

[0028] Specifically, refer to Figure 1 and Figure 2 , the component fixing assembly includes a first motor 207, a second motor 213, a steel ball 212, a second telescopic cylinder 211, a mounting bracket 210, and a V-block clamping tooling 209.

[0029] More specifically, refer to Figure 2, the first motor 207 and the second motor 213 are respectively installed on both sides of the top of the fixed plate 201. A plurality of steel round tubes are arranged between the first motor 207 and the second motor 213. A V-block clamping tool 209 is clamped outside one of the steel round tubes, and the bottom of the steel round tube is attached to a lower roller installed on the top of the fixed plate 201.

[0030] Further, referring to Figure 2 , steel balls 212 are arranged between the plurality of steel round tubes. The second telescopic cylinder body 211 passes through the inside of the steel ball 212, and the other end of the second telescopic cylinder body 211 passes through an opening 206 opened on the surface of the fixed plate 201 and is installed in the mounting frame 210 at the bottom of the fixed plate 201.

[0031] Still further, referring to Figure 1 and Figure 4 , the circumferential welding assembly includes an annular electric slide rail 205, an electric slider 202, a welding robot 203, a circular groove 214, a driving motor 208 and a part placement frame 204.

[0032] It should be noted that, referring to Figure 1 , the annular electric slide rail 205 is installed outside the device bottom shell 1. One end of the annular electric slide rail 205 is slidably connected to an electric slider 202, and a welding robot 203 is installed on the top of the electric slider 202.

[0033] It should be noted that, referring to Figure 4 , a circular groove 214 is opened on the side of the electric slider 202. A driving motor 208 is installed inside the circular groove 214. One end of the driving motor 208 extending out of the circular groove 214 is connected to a part placement frame 204. A large number of welding parts are neatly placed in the part placement frame 204. Since the part placement frame 204 is connected to the electric slider 202 through the driving motor 208, when the welding robot 203 needs to adjust its position to weld different parts of the parts, the electric slider 202 will drive the part placement frame 204 to move synchronously with the welding robot 203. This synchronous movement ensures that the welding robot 203 can quickly grab the required parts at any required position without waiting for the parts to be manually sent to the designated position, greatly improving the flexibility and efficiency of production and enabling the welding operation to be carried out continuously and efficiently. When the parts in the part placement frame 204 need to be replaced or replenished, the worker can start the driving motor 208 to drive the part placement frame 204 to flip. During the flipping process, the parts inside the part placement frame 204 will pour out under the action of gravity, facilitating the worker to quickly replace or replenish new parts. This not only saves manpower but also greatly shortens the time for part replacement. The worker can complete the replacement or replenishment of parts in a short time, ensuring that the welding operation can continue without interruption due to part shortage.

[0034] It should be introduced that, referring to Figure 1, a second square hole 3 is formed at the top of the device bottom shell 1, and a filter mesh body 301 is installed inside the second square hole 3.

[0035] Notably, referring to Figure 1 and Figure 3 , arc-shaped holes 308 are formed on both sides of the bottom of the device bottom shell 1, and activated carbon filter meshes 309 are installed inside the arc-shaped holes 308. One end of a connecting rod 302 is fixed to each of the two sides inside the device bottom shell 1. A double-shaft motor 303 is installed between the two connecting rods 302. The two ends of the wire on the double-shaft motor 303 are respectively connected to a first rotating rod 304 and a second rotating rod 306. When the welding operation starts, a large amount of welding fume will be generated by the high-temperature molten metal. To quickly capture this welding fume, the double-shaft motor 303 is started to drive the exhaust fan blades 305 at the same time. When the exhaust fan blades 305 rotate at a high speed, a strong suction force is generated, and the welding fume outside the welding area is quickly drawn into the device bottom shell 1. After the welding fume enters the device bottom shell 1, it first passes through the center position of the centrifugal impeller 307. The centrifugal impeller 307 is driven by the double-shaft motor 303, and its high-speed rotation generates a stronger suction force, drawing the welding fume in again and giving it a certain centrifugal speed. Under the action of the centrifugal impeller 307, the welding fume is thrown towards a plurality of centrifugal blades around it. These centrifugal blades enable the welding fume to be thrown out along the surface of the blades, further dispersed and refined. The welding fume thrown out by the centrifugal impeller 307 will then come into contact with the activated carbon filter mesh 309. Harmful substances in the welding fume, such as particulate matter and harmful gases, will be adsorbed on the surface or pores of the filter mesh when passing through the activated carbon filter mesh 309, thus realizing the purification treatment of the welding fume.

[0036] It should be emphasized that referring to Figure 3 , an exhaust fan blade 305 is installed at the top of the first rotating rod 304, and a centrifugal impeller 307 is installed at the bottom of the second rotating rod 306.

[0037] When using an automatic welding equipment for the inclined columns of an industrial railing, workers first correctly place the product parts to be welded, such as steel round tubes, perforated balls, etc., into the part fixing fixture on the welding platform according to the design drawings and process requirements. Once the parts are placed in the fixing fixture, the V-block clamping cylinder is immediately started to clamp the inclined-section steel pipe, ensuring that it will not move or shake during the welding process. At the same time, the cylinder on the right side is started to push and tighten each part, further strengthening the stability of the parts in the fixture. Next, the operator turns on the power of the annular electric slide rail 205, and the annular electric slide rail 205 starts to work, driving the electric slider 202 to move in a circular motion along the slide rail. The electric slider 202 is connected to the welding robot 203, so the welding robot 203 also moves in a circular motion along the slide rail accordingly, enabling the welding robot 203 to easily perform all-round operations around the device and directly move to any position or angle at the top of the device. After the welding robot 203 moves to the appropriate position, the first telescopic cylinder body 103 is started to lower the upper roller 104. The upper roller 104 cooperates with the lower roller in the part fixing fixture to tightly press the parts, ensuring that the parts will not be displaced due to external forces during the welding process. Subsequently, the rotary pressurizing cylinder returns to its original position to prepare for the next welding operation. After all preparations are completed, the welding robot 203 starts to perform spot welding operations. The robot controls the welding torch to perform spot welding on the parts. After the spot welding is completed, the second telescopic cylinder body 211 that fixes the steel ball 212 on the welding platform retracts to make room for the rotation of the product. Then, the motor is started to drive the product to rotate. While the product is rotating, the welding robot 203 continues to perform full welding operations. After the full welding is completed, the lower pressing fixture returns to its original position to release the parts. At this time, the worker can manually complete the blanking operation, remove the welded product from the welding platform, and prepare for the next production by loading materials. A large number of welded parts are neatly placed in the part placement frame 204. Since the part placement frame 204 is connected to the electric slider 202 through the drive motor 208, when the welding robot 203 needs to adjust its position to weld different parts of the parts, the electric slider 202 will drive the part placement frame 204 to move synchronously with the welding robot 203. This synchronous movement ensures that the welding robot 203 can quickly grab the required parts at any position where they are needed without waiting for the parts to be manually sent to the designated position, greatly improving the flexibility and efficiency of production and enabling the welding operation to be carried out continuously and efficiently. When the parts in the part placement frame 204 need to be replaced or replenished, the worker can start the drive motor 208 to drive the part placement frame 204 to flip. During the flipping process, the parts inside the part placement frame 204 will pour out under the action of gravity, facilitating the worker to quickly replace or replenish new parts. This not only saves manpower but also greatly shortens the time for part replacement. The worker can complete the replacement or replenishment of parts in a short time to ensure that the welding operation can continue without interruption due to part shortages. When the welding operation starts, a large amount of welding fume will be generated by the high-temperature molten metal.In order to quickly capture this welding fume, the dual-axis motor 303 is started to drive the exhaust fan blade 305 at the same time. When the exhaust fan blade 305 rotates at a high speed, a strong suction force is generated, and the welding fume outside the welding area is quickly drawn into the device bottom shell 1. After the welding fume enters the device bottom shell 1, it first passes through the central position of the centrifugal impeller 307. The centrifugal impeller 307 is driven by the dual-axis motor 303, and its high-speed rotation generates a stronger suction force, drawing the welding fume in again and giving it a certain centrifugal speed. Under the action of the centrifugal impeller 307, the welding fume is thrown towards multiple surrounding centrifugal blades, and these centrifugal blades enable the welding fume to be thrown out along the blade surface, further dispersed and refined. The welding fume thrown out by the centrifugal impeller 307 will then come into contact with the activated carbon filter screen 309. Harmful substances in the welding fume, such as particulate matter and harmful gases, will be adsorbed on the surface or pores of the filter screen when passing through the activated carbon filter screen 309, thus realizing the purification treatment of the welding fume.
