Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel roller production, and particularly relates to a welding device for steel roller production. Background Art
[0002] As the name implies, a steel roller is a roller made of steel. The production process of a steel roller includes blanking, turning processing, welding combination, heat treatment, re-turning, calibration, etc. Among them, the welding combination is to weld structures such as reinforcing ribs, both ends of the shaft, and end plates into an inner sleeve, and then weld the roller body of the seamless steel pipe to the end plate of the inner sleeve to complete the welding combination work.
[0003] When the existing welding device for steel roller production is welding, welding slag is formed on the surface of the weld due to factors such as oxidation. If welding needs to be done several times, the welding will be unstable due to the obstruction of the welding slag. Therefore, workers need to manually knock off the welding slag or use special equipment to remove the welding slag, which affects the continuity of welding and results in a longer welding time. Also, the welding slag needs to be knocked off before grinding to reduce the wear of the grinding parts, increasing the time consumption. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a welding device for steel roller production to solve the technical problems mentioned in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A welding device for steel roller production, including a base. A second motor is installed on one side of the base, and a grinding rod is connected to the output end of the second motor. A guiding mounting seat is connected to the other side of the base, and a rotating shaft penetrates through the top of the guiding mounting seat. Bevel gears are connected to one end of the rotating shaft and the outside of the grinding rod respectively. A semi-gear is sleeved on the outside of the rotating shaft. A rack penetrates through the back of the guiding mounting seat, and a knocking block is fixed to the back of the rack. A spring is connected between the rack and the guiding mounting seat.
[0006] By adopting the above technical solution, the grinding rod on the output end of the second motor drives the rotating shaft to rotate through the meshing of two bevel gears, so that the semi-gear rotates. After the semi-gear rotates, when the teeth of the semi-gear correspond to the rack, meshing occurs. At this time, the rack moves upward to drive the knocking block away from the roller body and the inner sleeve, and the spring is compressed under force. When the teeth of the semi-gear do not correspond to the rack, the meshing ends. At this time, the spring drives the rack to move downward to drive the knocking block close to the roller body and the inner sleeve, so as to knock on the weld between the roller body and the inner sleeve, and then knock off the welding slag on the surface of the weld. Then, the rack and the knocking block move up and down reciprocally to continuously knock, so as to clean the subsequent welding slag, and the weld with the welding slag removed is ground by the rotating grinding rod.
[0007] Further, the semi-gear meshes with the rack, and the two bevel gears mesh with each other.
[0008] By adopting the above technical solution, after the polishing rod rotates, it drives the rotating shaft to rotate through the meshing of two bevel gears, so that the half gear rotates. After the half gear rotates, when the teeth of the half gear correspond to the rack, meshing occurs. At this time, the rack moves upward, driving the knocking block away from the roller body and the inner sleeve.
[0009] Furthermore, the rack is slidably connected to the guiding mounting seat.
[0010] By adopting the above technical solution, while the half gear and the spring cooperate to make the rack move up and down reciprocally, the guiding mounting seat guides the rack.
[0011] Furthermore, a first motor is installed on one side of the top of the base, and a roller is connected to the output end of the first motor. The roller body is placed on the top of the roller, and an inner sleeve is arranged inside the roller body. A welding torch is installed above the other side of the base.
[0012] By adopting the above technical solution, the staff puts the inner sleeve into the roller body, then places the roller body on the tops of the two rollers, and makes the welding torch correspond to the joint between the roller body and the inner sleeve. Then the staff turns on the first motor and the welding torch. After the welding torch starts, it welds at the joint between the roller body and the inner sleeve, thus welding the roller body and the inner sleeve together. After the first motor starts, it drives the roller to rotate, thus driving the roller body and the inner sleeve to rotate, so as to facilitate one-time welding forming.
[0013] Furthermore, the knocking block abuts against the roller body and the inner sleeve, and the bottom of the knocking block is arc-shaped.
[0014] By adopting the above technical solution, the knocking block approaches the roller body and the inner sleeve, thus knocking on the weld seam between the roller body and the inner sleeve, and then knocking off the welding slag on the surface of the weld seam.
[0015] Furthermore, there are two first motors and rollers, and the two first motors and rollers are equidistantly distributed.
[0016] By adopting the above technical solution, after the first motor starts, it drives the roller to rotate, thus driving the roller body and the inner sleeve to rotate, so as to facilitate one-time welding forming.
[0017] Furthermore, there are three half gears, racks, knocking blocks and springs, and the three half gears, racks, knocking blocks and springs are equidistantly distributed.
[0018] By adopting the above technical solution, after the half gear rotates, when the teeth of the half gear correspond to the rack, meshing occurs. At this time, the rack moves upward, driving the knocking block away from the roller body and the inner sleeve, and the spring is compressed by force. When the teeth of the half gear do not correspond to the rack, the meshing ends. At this time, the spring drives the rack to move downward, driving the knocking block to approach the roller body and the inner sleeve, thus knocking on the weld seam between the roller body and the inner sleeve, and then knocking off the welding slag on the surface of the weld seam.
[0019] Furthermore, the included angle between the three semi-gears is 120°.
[0020] By adopting the above technical solution, there is an included angle between the three semi-gears, so that the three racks and the three knocking blocks staggeringly knock the welding slag, making the knocking work more continuous and reducing the interval.
[0021] In summary, the main beneficial effects of the present utility model are as follows:
[0022] With the settings of the grinding rod, bevel gear, guiding mounting seat, semi-gear, rack, knocking rod and spring in the present utility model, the grinding rod on the output end of the second motor drives the rotating shaft to rotate through the meshing of two bevel gears, so as to rotate the semi-gear. After the semi-gear rotates, when the teeth of the semi-gear correspond to the rack, they mesh. At this time, the rack moves upward to drive the knocking block away from the roller body and the inner sleeve, and the spring is compressed by force. When the teeth of the semi-gear do not correspond to the rack, the meshing ends. At this time, the spring drives the rack to move downward to drive the knocking block close to the roller body and the inner sleeve, so as to knock the weld between the roller body and the inner sleeve, and then knock off the welding slag on the surface of the weld. After that, the rack and the knocking block move up and down reciprocally to continuously knock, so as to facilitate the cleaning of the subsequent welding slag, and the weld with the welding slag removed is polished by the rotating grinding rod; the structure is simple and the operation is convenient, which can automatically clean the welding slag and can polish the weld flat.
