Description

Technical Field

[0001] This utility model belongs to the field of pressure pipeline welding technology, specifically relating to an adjustable welding device for pressure pipeline production. Background Technology

[0002] In modern industry, pressure pipelines are widely used in petroleum, chemical, and power industries. Their welding quality directly affects the safety and stability of the entire system. To ensure welding accuracy and efficiency, welding equipment plays a key role in the production process of pressure pipelines.

[0003] Currently, most pressure pipeline welding devices on the market adopt a fixed clamping structure. Although this can achieve basic pipeline fixation, it has obvious limitations in actual operation. For example, when welding specific parts of the pipeline is required, the clamping angle and orientation cannot be flexibly adjusted. Operators often need to repeatedly adjust the pipeline position and even need to use additional auxiliary tools to change the viewing angle. This not only increases the difficulty of operation and time cost, but may also lead to a decrease in pipeline positioning accuracy due to frequent adjustments, affecting the welding quality.

[0004] Therefore, developing a welding device that can flexibly adjust the angle and orientation during pressure pipeline welding clamping is key to solving the above problems and improving the welding quality and production efficiency of pressure pipelines. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable welding device for pressure pipeline production, which enables flexible adjustment of the angle and orientation of the pressure pipeline during welding clamping, allowing operators to easily weld any part without repeatedly manually adjusting the pipeline.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An adjustable welding device for pressure pipeline production includes a mounting frame and a fixed frame disposed diagonally above the mounting frame. Two reverse screws are rotatably connected internally to the fixed frame. Clamping plates are threaded to the outer ends of the two reverse screws. At least one limiting strip is fixed internally to the fixed frame and is slidably connected to the two clamping plates. A first motor is mounted on one side of the fixed frame. The output end of the first motor passes through the fixed frame and is fixedly connected to one of the reverse screws. A synchronous transmission mechanism is installed between the two reverse screws. A drive mechanism is mounted on the mounting frame.

[0008] The synchronous transmission mechanism includes transmission wheels fixed to the ends of the two opposing screws, and a transmission belt drives between the two transmission wheels.

[0009] The drive mechanism includes a bracket fixed to the top of the mounting frame, an electric push rod rotatably connected inside the bracket, the stroke rod of the electric push rod being fixedly connected to the fixed frame, and a rotating mechanism being mounted on the electric push rod.

[0010] The rotating mechanism includes a driven gear fixed to the outside of the electric push rod, a second motor is mounted on the side wall of the mounting bracket, a driving gear is fixed to the output end of the second motor, and the driving gear is meshed with the driven gear.

[0011] At least one reinforcing telescopic bar is fixed between the driven gear and the fixed frame.

[0012] The driven gear is larger than the driving gear.

[0013] The clamping plate includes two mounting plates, an upper and a lower one, and a clamping piece located in the middle. The two mounting plates are provided with magnetic slots on the side that is close to each other. The clamping piece is provided with magnetic strips at both the upper and lower ends, and the magnetic strips are magnetically attracted to the magnetic slots. The two reverse screws are threadedly connected to the two mounting plates respectively, and the limiting strip is slidably connected to the two mounting plates.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention utilizes an electric push rod to adjust the position of the pressure pipe. By starting a second motor, the driving and driven gears rotate, thereby adjusting the angle of the pressure pipe. This allows for flexible adjustment of the angle and orientation of the pressure pipe during welding clamping, eliminating the need for repeated manual adjustments and enabling easy welding of any part. This significantly reduces operational difficulty and saves time, while also effectively improving pipe positioning accuracy, ensuring welding quality, and reducing rework.

Detailed Implementation

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, an adjustable welding device for pressure pipeline production includes a mounting frame 1 and a fixed frame 2 positioned diagonally above the mounting frame 1. Two opposing screws 3 are rotatably connected inside the fixed frame 2. These opposing screws 3 are two screws with opposite helical directions fixed together, a common design. Clamping plates 4 are threaded to the outer ends of the two opposing screws 3. At least one limiting strip 5 is fixed inside the fixed frame 2 and slidably connected to the two clamping plates 4. A first motor 6 is mounted on one side of the fixed frame 2. The output end of the first motor 6 passes through the fixed frame 2 and is fixedly connected to one of the opposing screws 3. A synchronous transmission mechanism is installed between the two opposing screws 3. (Refer to attached diagram). Figure 3 The synchronous transmission mechanism includes a transmission wheel 7 fixed to the ends of two reverse screws 3, and a transmission belt 8 drives the two transmission wheels 7. When one of the reverse screws 3 rotates, it can drive the transmission wheel 7 on it to rotate, and through the transmission belt 8, it can drive the other transmission wheel 7 to rotate, so that the two reverse screws 3 rotate synchronously. The outer side of the transmission wheel 7 is provided with teeth, and the inner wall of the transmission belt 8 is also provided with teeth that mesh with the teeth on the outer side of the transmission wheel 7, thereby enhancing the meshing transmission effect.

[0024] When clamping and welding pressure pipes, the first motor 6 can be driven so that the output end of the first motor 6 drives one of the reverse screws 3 to rotate. Through the transmission wheel 7 and the transmission belt 8, the other reverse screw 3 is driven synchronously. The two clamping plates 4 are engaged with the reverse screws 3 and guided by the limiting strip 5, so that the two clamping plates 4 can move in opposite directions to clamp the pressure pipes, thus making it convenient for users to use the welding device to weld the pressure pipes.

[0025] The drive mechanism is installed on the mounting bracket 1.

[0026] See attached document Figure 1 and attached Figure 2 The drive mechanism includes a bracket 10 fixed to the top of the mounting frame 1, and an electric push rod 9 is rotatably connected inside the bracket 10. The stroke rod of the electric push rod 9 is fixedly connected to the fixed frame 2.

[0027] When it is necessary to adjust the translation position of the pressure pipe, the electric push rod 9 can be driven so that the stroke rod of the electric push rod 9 drives the fixed frame 2 to move back and forth, and drives the pressure pipe after being clamped to move, thereby adjusting the translation position of the pressure pipe after clamping, which makes it convenient for users to weld different positions of the pressure pipe.

[0028] The electric push rod 9 is equipped with a rotating mechanism.

[0029] See attached document Figure 1 and attached Figure 2 The rotating mechanism includes a driven gear 11 fixed to the outside of the electric push rod 9, a second motor 13 is mounted on the side wall of the mounting bracket 1, and a driving gear 12 is fixed to the output end of the second motor 13, and the driving gear 12 is meshed with the driven gear 11.

[0030] When adjusting the angle of the clamped pressure pipe, the second motor 13 can be driven, so that the output end of the second motor 13 drives the drive gear 12 to rotate. Through the meshing connection between the drive gear 12 and the second motor 13, the drive gear 12 can drive the second motor 13 to rotate. The second motor 13 drives the electric push rod 9 and the clamped pressure pipe to rotate, so that the user can weld at different angles of the pressure pipe. Furthermore, the driven gear 11 is larger than the drive gear 12. Through this setting, the rotation speed of the driven gear 11 is slower than the rotation speed of the drive gear 12. This reduces the rotation speed of the electric push rod 9, thus avoiding over-adjustment during angle adjustment. Furthermore, at least one reinforcing telescopic bar 14 is fixed between the driven gear 11 and the fixed frame 2. The setting of the reinforcing telescopic bar 14 makes the connection between the fixed frame 2 and the driven gear 11 more stable, reducing the offset of the fixed frame 2. The driven gear 11 can also be rotatably connected to the mounting frame 1 to further enhance its stability. The reinforcing telescopic bar 14 can be composed of two sleeved tubes of different sizes, one end of which is connected to the driven gear 11 and the other end of which is connected to the fixed frame 2.

[0031] See attached document Figure 3The clamping plate 4 includes two mounting plates 41, one above the other, and a clamping piece 42 located in the middle. Each mounting plate 41 has a magnetic slot 43 on its side closest to each other. The clamping piece 42 has magnetic strips 44 at both its upper and lower ends, and these strips are magnetically attached to the magnetic slots 43. Two reverse screws 3 are threadedly connected to the two mounting plates 41, and a limiting strip 5 is slidably connected to the two mounting plates 41. Different clamping pieces 42 can be used to clamp pressure pipes of different sizes. Each clamping piece 42 contains different clamping strips for different sizes. The grooves that match the pressure pipes allow for clamping different pressure pipes. When changing, the clamping piece 42 can be directly removed and attached between the two mounting plates 41, and then secured in the magnetic slot 43 by the magnetic strip 44. The two clamping pieces 42 on the mounting bracket 2 are in close proximity to each other, so that when the mounting plate 41 moves the clamping piece 42, the clamping piece 42 can clamp the pressure pipe by blocking the magnetic slot 43 and the magnetic strip 44, thus ensuring the clamping effect of the pressure pipe.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
