Description

Technical Field

[0001] This utility model relates to the field of welding equipment, specifically a high-precision pipe welding device. Background Technology

[0002] Welding, as an important manufacturing process, is widely used in industrial manufacturing, construction, and automobile manufacturing. While traditional welding equipment can meet basic welding needs, it faces numerous technical bottlenecks when demanding high-precision welding. For example, during processing, the positioning of materials is not precise enough, easily leading to welding errors. Furthermore, the low level of automation in welding equipment limits production efficiency, and dynamic control of weld quality is difficult to achieve during the welding process, thus affecting the quality of the finished product.

[0003] A search revealed a Chinese patent document disclosing a high-precision seamless welding device for stainless steel pipes [Application No.: 202321368892.1, Publication No.: CN219924918U]. This device includes a worktable with first threaded holes at both ends of the upper outer surface of the worktable. Limiting components are fixedly installed at both ends of the upper outer surface of the worktable. This device ensures the welding effect through two limiting components. However, it is limited by its structure, has limited processing feasibility and processing types, and cannot adapt to multi-variety, batch production modes, resulting in low efficiency. Utility Model Content

[0005] A high-precision pipe welding device, characterized in that: the high-precision pipe welding device includes a base, a support frame, an electric welder, a first slide rail, a second slide rail, a movable rail, and two material support frames. The first slide rail is located on the top of the base, the second slide rail is located on the top of the base, the support frame is located on the top of the base and is positioned between the first and second slide rails, the movable rail is located on the top of the base, one material support frame is movably mounted on the first slide rail, the other material support frame is movably mounted on the second slide rail, and the electric welder is movably mounted on the movable rail.

[0006] Preferably, the material support frame includes a structural frame, rollers, a variable speed motor, a first roller frame, and a second roller frame. The top of the structural frame is provided with rollers, the first roller frame, and the second roller frame. The first roller frame is movably installed on one side of the structural frame, and the second roller frame is movably installed on the other side of the structural frame. The rollers are arranged between the first roller frame and the second roller frame. The power output end of the variable speed motor is connected to the rollers, and the variable speed motor can drive the rollers to rotate.

[0007] Through the aforementioned technical solution, the movable installation method of roller frame one and roller frame two ensures that the material support frame can adaptively adjust to workpieces of different specifications and sizes during use, greatly improving the applicability of the equipment. The rollers are driven by a variable-speed motor, which can flexibly adjust the rotation speed according to the workpiece's transport requirements, thereby achieving precise material feeding. This structure not only improves the positioning accuracy during welding but also ensures the stability of welding quality.

[0008] Preferably, a double-gear double-rack symmetrical transmission mechanism is installed between roller frame one and roller frame two. The double-gear double-rack symmetrical transmission mechanism includes rack one, rack two, gear one, and gear two. One side of rack one is connected to roller frame one, and the other side of rack one is connected to gear one. One side of gear one is connected to rack one, and the other side of gear one is connected to gear two. One side of gear two is connected to gear one, and the other side of gear two is connected to rack two. One side of rack two is connected to gear two, and the other side of rack two is connected to roller frame two.

[0009] Through the above technical solution, the movement of roller frame one and roller frame two can be synchronously adjusted through a double-gear double-rack symmetrical transmission mechanism. This design not only ensures the parallel relationship between roller frame one and roller frame two, but also improves the stability and accuracy of the material support frame during workpiece transfer.

[0010] Preferably, a drive device is provided on one side of the roller frame, and the drive device can drive the roller frame.

[0011] Through the above technical solution, the drive device can achieve active driving or precise positioning of the first roller frame. By driving the first roller frame, the second roller frame can move synchronously through the double gear and double rack symmetrical transmission mechanism. The position can be adjusted according to the outer diameter of steel pipes of different sizes, thereby ensuring the stability and positioning accuracy of the steel pipes during the welding process.

[0012] Preferably, the bottom of the structural frame is provided with a slide rail seat.

[0013] Through the above technical solution, the slide rail base can be movably installed on slide rail one or slide rail two, allowing the entire structural frame to move flexibly on slide rail one or slide rail two. This design not only increases the flexibility of the equipment but also enables the material support frame to be quickly adjusted between different positions according to welding requirements, improving the adaptability and work efficiency of the equipment.

[0014] Preferably, the structural frame is I-shaped.

[0015] Through the above technical solutions, the I-beam structure can provide good support and shock absorption performance, effectively absorb and disperse the vibration generated during equipment operation during welding, improve welding accuracy and finished product quality, and the hollow design of the I-beam structure reduces the overall weight of the structural frame and reduces the burden of moving the equipment.

[0016] Preferably, the roller is covered with a rubber layer with a rough surface.

[0017] Through the above technical solution, the rubber layer on the rough surface can significantly improve the friction of the workpiece during the transmission process, prevent the workpiece from sliding or deviating, and also has good shock absorption and buffering functions. During the transmission of the workpiece, it can absorb the small vibrations brought by the operation of the equipment or the external environment, and prevent the workpiece from being displaced or tilted due to vibration.

[0018] Preferably, the axes of the rollers of the two material support frames are on the same straight line.

[0019] The above technical solution ensures that the workpiece remains horizontal throughout the transfer and welding process. This design effectively avoids workpiece shifting or wobbling caused by inconsistent roller heights or tilting, thus improving welding accuracy and workpiece processing quality.

[0020] Preferably, the lifting frame includes a mounting base, a hydraulic cylinder, and a lifting plate. The mounting base is located on top of the base, the hydraulic cylinder is located on top of the mounting base, and the lifting plate is located on top of the hydraulic cylinder.

[0021] Through the above technical solution, the use of hydraulic cylinders enables precise displacement adjustment of the lifting plate. This allows the workpiece to be raised and lowered to a specified height according to welding process requirements, while maintaining stability during the lifting process and preventing displacement or damage to the workpiece due to severe vibration. This design improves the flexibility and applicability of the welding equipment.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. The rollers of the two material support frames of this high-precision pipe welding equipment have their axes aligned in a straight line.

Detailed Implementation

[0031] 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.

[0032] Please see Figures 1 to 4 This utility model provides a technical solution:

[0033] A high-precision pipe welding device, characterized in that: the high-precision pipe welding device includes a base 101, a support frame 102, an electric welder 103, a first slide rail 104, a second slide rail 105, a movable rail 106, and two material support frames 107. The first slide rail 104 is located on the top of the base 101, the second slide rail 105 is located on the top of the base 101, the support frame 102 is located on the top of the base 101 and is positioned between the first slide rail 104 and the second slide rail 105, the movable rail 106 is located on the top of the base 101, one material support frame 107 is movably mounted on the first slide rail 104, the other material support frame 107 is movably mounted on the second slide rail 105, and the electric welder 103 is movably mounted on the movable rail 106.

[0034] Specifically, the material support frame 107 includes a structural frame 201, rollers 202, a variable speed motor 203, a first roller frame 204, and a second roller frame 205. The top of the structural frame 201 is provided with rollers 202, first roller frame 204, and second roller frame 205. The first roller frame 204 is movably installed on one side of the structural frame 201, and the second roller frame 205 is movably installed on the other side of the structural frame 201. The rollers 202 are located between the first roller frame 204 and the second roller frame 205. The power output end of the variable speed motor 203 is connected to the rollers 202, and the variable speed motor 203 can drive the rollers 202 to rotate. When the pipe is placed on the support frame 107, the roller 202 at the bottom plays a supporting and driving role in rotation. The variable speed motor 203 of the two support frames 107 drives the roller 202 to rotate synchronously, which can ensure that the two pipe sections move at the same frequency, thereby improving the welding accuracy. The roller frame 1 204 and the roller frame 205 play a positioning and auxiliary rotation function to ensure the precision of welding.

[0035] Specifically, a double-gear double-rack symmetrical transmission mechanism is installed between roller frame 1 204 and roller frame 2 205. The double-gear double-rack symmetrical transmission mechanism includes rack 1 401, rack 2 402, gear 1 403, and gear 2 404. One side of rack 1 401 is connected to roller frame 1 204, and the other side of rack 1 401 is connected to gear 1 403. One side of gear 1 403 is connected to rack 1 401, and the other side of gear 1 403 is connected to gear 2 404. One side of gear 2 404 is connected to gear 1 403, and the other side of gear 2 404 is connected to rack 2 402. One side of rack 2 402 is connected to gear 2 404, and the other side of rack 2 402 is connected to roller frame 2 205. This mechanical structure is very simple and not only ensures the parallel relationship between roller frame 1 204 and roller frame 2 205, but also improves the stability and accuracy of the material support frame 107 during workpiece transmission.

[0036] Specifically, a drive device 207 is provided on one side of the roller frame 204, which can drive the roller frame 204. The drive device 207 can realize active driving or precise limiting of the roller frame 204. By driving the roller frame 204, the roller frame 205 can move synchronously through the double gear and double rack symmetrical transmission mechanism, thereby ensuring the stability and positioning accuracy of the steel pipe during the welding process. At the same time, it enables the equipment to meet the welding needs of steel pipes from small diameter to large diameter, reducing the time required for frequent replacement or adjustment of support components due to size differences.

[0037] Specifically, the bottom of the structural frame 201 is provided with a slide rail seat 206, which can be movably installed on slide rail one 104 or slide rail two 105, so that the entire structural frame 201 can move flexibly on slide rail one 104 or slide rail two 105. The setting of the slide rail seat 206 makes the movement of the structural frame 201 smooth and precise, avoiding the impact of deviations during movement on the accuracy of welding.

[0038] Specifically, the structural frame 201 is I-shaped. The I-shaped structure provides good support and shock absorption performance. The I-shaped structure is known for its high strength and resistance to deformation. It can effectively distribute the load and reduce the deformation of the structural frame 201 caused by external forces during welding. It can effectively absorb and disperse the vibration generated during equipment operation during welding, improve welding accuracy and finished product quality. The hollow design of the I-shaped structure reduces the overall weight of the structural frame 201 and reduces the burden of moving the equipment.

[0039] Specifically, the roller 202 is covered with a rough-surfaced rubber layer. This rough-surfaced rubber layer significantly increases the friction of the workpiece during transport, preventing it from slipping or shifting. It also provides excellent shock absorption and cushioning, absorbing minor vibrations from equipment operation or the external environment during transport, preventing displacement or tilting of the workpiece due to vibration. Simultaneously, the flexibility of the rubber material effectively protects the workpiece surface, preventing scratches or damage from the hard roller.

[0040] Specifically, the axes of the rollers 202 of the two support frames 107 are on the same straight line. This positional relationship ensures that the workpiece is subjected to uniform force during the conveying process. Especially when handling long or heavy workpieces, the consistency of the axes also optimizes the coordination of the support frames 107, enabling the two support frames 107 to move synchronously, thereby avoiding workpiece positioning deviations caused by the asynchronous movement of the support frames 107 during the welding process.

[0041] Specifically, the lifting frame 102 includes a mounting base 301, a hydraulic cylinder 302, and a lifting plate 303. The mounting base 301 is located on top of the base 101, the hydraulic cylinder 302 is located on top of the mounting base 301, and the lifting plate 303 is located on top of the hydraulic cylinder 302. The lifting plate 303 enables the lifting frame 102 to provide reliable workpiece support and prevent the workpiece from being displaced or damaged due to severe vibration.
