Description
Technical Field
[0001] This utility model relates to the technical field of steel cylinder production equipment, and in particular to an intelligent welding positioning device for an inner ring welding machine in steel cylinder production. Background Technology
[0002] The intelligent welding positioning device for the inner ring welding of steel cylinders is a piece of equipment used to accurately determine the welding position of the inner ring of the cylinder. In the steel cylinder manufacturing process, the welding quality of the inner ring is crucial, as it ensures the sealing and stability of the cylinder's internal structure.
[0003] Existing intelligent welding positioning devices can improve the precision of welding positions, ensuring the accuracy and consistency of welding positions, and at the same time achieve rapid positioning, reducing the preparation time before welding. Both the pressure resistance and sealing performance of the gas cylinder can be better guaranteed, reducing quality problems caused by inaccurate welding positions.
[0004] However, in actual use cases, the welding process for gas cylinders generally involves welding the inner ring of the cylinder first, and then welding from the outside. This process involves multiple clamping, position adjustment, and welding head replacement operations, which increases the total welding time for a single gas cylinder and is not conducive to improving the welding efficiency of gas cylinders.
[0005] Therefore, this application provides an intelligent welding positioning device for an inner ring welding machine in steel cylinder production to meet the requirements. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an intelligent welding positioning device for an inner ring welding machine in steel cylinder production.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent welding positioning device for an inner ring welding machine in steel cylinder production, comprising:
[0008] Welding machine;
[0009] A welding assembly is placed on one side of a welding machine. The welding assembly includes a bracket fixed to one side of the welding machine and a base set on one side of the bracket. An inner welding gun is fixedly connected to the base. A top plate is provided on the top of the base. A rotating shaft is fixedly connected to the top plate. The top plate is rotatably connected to the base through the rotating shaft. An outer welding gun is slidably connected to the top plate. A laser sensor is fixedly connected to both the inner and outer welding guns.
[0010] An adjustment assembly is placed on top of the welding assembly and is used to push the outer welding gun for adjustment. The adjustment assembly includes a first motor fixed to the top of the top plate. The output end of the first motor and the top plate are both fixedly connected to pulleys. The pulley on the side closer to the top plate is threadedly connected to the outer welding gun. The pulley is driven by a transmission belt.
[0011] Furthermore, a limiting plate is fixedly connected to one end of the outer welding gun near the pulley, and the limiting plate is engaged with the pulley.
[0012] The beneficial effects of adopting the above-mentioned further solution are: to avoid excessive movement of the outer welding gun leading to separation from the pulley, and to prevent damage to the positioning device.
[0013] Furthermore, a turntable is fixedly connected to the side of the base near the support, and is rotatably connected to the support. A second motor is fixedly connected to the side of the support near the turntable, and the output end of the second motor is fixedly connected to the turntable.
[0014] The beneficial effect of adopting the above-mentioned further solution is that adjusting the angle between the base and the inner welding gun makes it easier for the inner welding gun to be fed into the interior of the workpiece, which helps to improve the flexibility of the work.
[0015] Furthermore, a slider is fixedly connected to one end of the turntable near the support, and the slider is rotatably connected to the support.
[0016] The beneficial effect of adopting the above-mentioned further solution is that it can increase the stability of the turntable when it rotates on the support.
[0017] Furthermore, a hydraulic telescopic rod is rotatably connected between the base and the top plate.
[0018] The beneficial effect of adopting the above-mentioned further solution is that it adjusts the angle between the inner welding gun and the outer welding gun, so that the inner welding gun and the outer welding gun can fit better on the workpiece, which facilitates welding of the workpiece or positioning of the weld.
[0019] Furthermore, a limiting block is fixedly connected to one end of the top plate on the outer welding gun, and the limiting block is slidably connected to the top plate.
[0020] The beneficial effect of adopting the above-mentioned further solution is that it keeps the external welding gun stable when moving, which helps to improve the stability of the external welding gun during use.
[0021] Furthermore, a ranging plate is fixedly connected to one end of the outer welding gun near the top plate, and a rangefinder is fixedly connected to the side of the top plate near the ranging plate.
[0022] The beneficial effect of adopting the above-mentioned further solution is that it verifies the deviation of the laser sensor measurement, thereby improving the accuracy of data detection.
[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0024] 1. By setting up welding components and activating the laser sensor, the outer and inner rings of the workpiece are simultaneously scanned. During the positioning of the weld seam, the deviation between the two weld seams is detected to ensure it does not exceed the range, preventing the outer ring from being difficult to adjust after the inner ring is welded. At the same time, the inner and outer welding guns are mirror-distributed. When the inner welding gun performs welding operations inside the workpiece, the outer welding gun performs auxiliary spot welding on the outside of the workpiece. In this way, the welding quality of the inner and outer rings is improved, and the problem of complicated intermediate auxiliary operations during workpiece welding is solved, which is conducive to improving the welding efficiency of steel cylinders.
[0025] 2. By setting up the adjustment component and starting the first motor, the first motor can drive the outer welding gun to move horizontally along its own thread line inside the top plate with the help of the pulley and the transmission belt. This allows the outer welding gun and the inner welding gun to generate relative movement. When the laser sensor detects a deviation between the outer ring and the inner ring of the workpiece, if the deviation is within the allowable range, the outer welding gun can be moved to the appropriate position and the welding operation can continue. If the deviation exceeds the allowable range, the laser sensor is moved to measure the deviation again. Through these operations, the flexibility and intelligence of the positioning device can be improved. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: an intelligent welding positioning device for an inner ring welding machine in steel cylinder production, comprising: a welding machine 1, which consists of a base, a movable base, an electric telescopic rod, a slide rail, a motor, and a clamp. The base is used to support other components. The clamp and the motor are mounted on the base. The motor is used to drive the clamp to rotate and weld the workpiece with the inner welding gun 24 and the outer welding gun 25. The electric telescopic rod moves the movable base on the slide rail and is used to push the bracket 21 to move on the welding machine 1.
[0037] like Figure 1 - Figure 2 As shown: Welding assembly 2, which is placed on one side of welding machine 1. Welding assembly 2 includes a bracket 21 fixed on one side of welding machine 1 and a base 22 set on one side of bracket 21. An inner welding gun 24 is fixedly connected to the base 22. A top plate 23 is set on the top of the base 22. A rotating shaft 27 is fixedly connected to the top plate 23. The top plate 23 is rotatably connected to the base 22 through the rotating shaft 27. An outer welding gun 25 is slidably connected to the top plate 23. A laser sensor 26 is fixedly connected to both the inner welding gun 24 and the outer welding gun 25.
[0038] like Figure 2 - Figure 3As shown: Adjustment component 3, located on top of welding component 2, is used to drive the outer welding gun 25 for adjustment. Adjustment component 3 includes a first motor 31 fixed to the top of top plate 23. The output end of the first motor 31 and the top plate 23 are both fixedly connected to pulleys 32. The pulley 32 closest to the top plate 23 is threadedly connected to the outer welding gun 25. A transmission belt 33 is driven by the pulley 32. By activating the laser sensor 26, the laser sensor 26 simultaneously scans the outer and inner rings of the workpiece. While positioning the weld seam, it detects whether the deviation between the two weld seams is too large, avoiding difficulty in adjusting the outer ring after the inner ring is welded. Furthermore, the inner welding gun 24 and the outer welding gun 25 are set in a mirror image, so that while the inner welding gun 24 welds the inside of the workpiece, the outer welding gun 25 welds the inside of the workpiece. External auxiliary spot welding improves the welding quality between the inner and outer rings and solves the problem of excessive auxiliary operations during welding, which is beneficial to improving the welding efficiency of the cylinder. By starting the first motor 31, the first motor 31 drives the outer welding gun 25 to move horizontally along its own thread line inside the top plate 23 through the cooperation of the pulley 32 and the transmission belt 33, so that the outer welding gun 25 and the inner welding gun 24 can move relative to each other. When the laser sensor 26 detects a deviation between the outer and inner rings, if the deviation is within the allowable range, the outer welding gun 25 is moved to a suitable position and the welding operation continues. If the deviation is outside the allowable range, the laser sensor 26 is moved to measure the deviation. Through the above operations, the flexibility and intelligence of the positioning device can be increased.
[0039] Furthermore, such as Figure 3 As shown: A limiting plate 34 is fixedly connected to one end of the outer welding gun 25 near the pulley 32. The limiting plate 34 is engaged with the pulley 32. By installing the limiting plate 34, the moving distance of the outer welding gun 25 is limited when the outer welding gun 25 moves, so as to prevent the outer welding gun 25 from moving excessively and separating from the pulley 32, and to prevent damage to the positioning device.
[0040] Furthermore, such as Figure 3 As shown: A turntable 35 is fixedly connected to the side of the base 22 near the support 21 and is rotatably connected to the support 21. A second motor 36 is fixedly connected to the side of the support 21 near the turntable 35. The output end of the second motor 36 is fixedly connected to the turntable 35. By installing a turntable 35 with a larger thickness, the connection between the base 22 and the support 21 is more stable. When the second motor 36 is started, the second motor 36 drives the base 22 to rotate through the turntable 35, adjusting the angle between the base 22 and the inner welding gun 24, making it easier for the inner welding gun 24 to be fed into the interior of the workpiece, which is beneficial to improving the flexibility of the work.
[0041] Furthermore, such as Figure 3As shown: A slider 37 is fixedly connected to one end of the turntable 35 near the bracket 21. The slider 37 is rotatably connected to the bracket 21. By opening a groove on the bracket 21 that matches the slider 37, the slider 37 and the groove cooperate to make the slider 37 and the bracket 21 more tightly connected, which can increase the stability of the turntable 35 when rotating on the bracket 21.
[0042] Furthermore, such as Figure 3 As shown: A hydraulic telescopic rod 38 is rotatably connected between the base 22 and the top plate 23. By activating the hydraulic telescopic rod 38, the hydraulic telescopic rod 38 pushes one side of the top plate 23, raising the top plate 23, thereby adjusting the angle between the inner welding gun 24 and the outer welding gun 25, so that the inner welding gun 24 and the outer welding gun 25 can better fit on the workpiece, which is convenient for welding the workpiece or positioning the weld.
[0043] Furthermore, such as Figure 4 As shown: One end of the top plate 23 on the outer welding gun 25 is fixedly connected to a limiting block 28. The limiting block 28 is slidably connected to the top plate 23. The limiting block 28 limits the outer welding gun 25 to prevent the outer welding gun 25 from rotating with the pulley 32, so that the outer welding gun 25 remains stable when moving, which helps to improve the stability of the outer welding gun 25 during use.
[0044] Furthermore, such as Figure 4 As shown: A distance measuring plate 4 is fixedly connected to one end of the outer welding gun 25 near the top plate 23, and a distance measuring instrument 5 is fixedly connected to one side of the top plate 23 near the distance measuring plate 4. By setting the initial position between the distance measuring plate 4 and the distance measuring instrument 5 as zero, when the deviation between the outer ring and the inner ring is too large, and after the two laser sensors 26 measure the deviation, the distance measuring instrument 5 is activated. The distance measuring instrument 5 measures the distance between itself and the distance measuring plate 4 to verify the deviation measured by the laser sensors 26, thereby improving the accuracy of data detection.
[0045] Working principle: such as Figure 1 - Figure 4As shown, the workpiece is first clamped between the fixtures on the welding machine 1. The electric telescopic rod on the welding machine 1 is activated to push the bracket 21 toward the workpiece. At the same time, the second motor 36 is activated. The second motor 36 drives the base 22 to rotate along the slider 37 via the turntable 35, adjusting the angle of the inner welding gun 24 so that the inner welding gun 24 can more easily enter the interior of the workpiece. Then, the hydraulic telescopic rod 38 is activated, and the limit block 28 retracts, causing the top plate 23 to rotate downward, so that the inner welding gun 24 and the outer welding gun 25 are in contact with the inner wall of the workpiece. The laser sensor 26 is activated, so that the laser sensor 26 scans the outer ring and inner ring of the workpiece simultaneously. While positioning the weld, it detects whether the deviation between the two welds is too large. If the deviation is outside the allowable range, the first motor 31 is activated, so that the first motor 31 pushes the outer welding gun 25 along its own path through the cooperation of the pulley 32 and the transmission belt 33. The threaded wire moves horizontally inside the top plate 23. At the same time, the limiting block 28 and the limiting plate 34 cooperate to limit the outer welding gun 25, improving the stability of the outer welding gun 25 during movement. Then, the outer welding gun 25 is moved to drive the laser sensor 26 to measure the weld. The rangefinder 5 is started, and the rangefinder 5 measures the distance between itself and the rangefinder plate 4. The deviation measured by the laser sensor 26 is verified. If the deviation is within the allowable range, the outer welding gun 25 is moved to a suitable position. The motor on the welding machine 1 is started to make the fixture drive the workpiece to rotate. The inner welding gun 24 and the outer welding gun 25 are started. The inner welding gun 24 welds the inside of the workpiece, while the outer welding gun 25 performs auxiliary spot welding on the outside of the workpiece. This improves the welding quality of the inner ring and the outer ring and solves the problem of too many auxiliary operations in the middle of the workpiece welding process, which is conducive to improving the welding efficiency of the steel cylinder.
[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
