Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to an open pipeline welding positioner. Background Art

[0002] In the traditional metal pipe welding process, the clamping of the pipe is usually achieved by welding positioners or chucks. These devices have some limitations when clamping the pipe, especially when the pipe has special-shaped features. Since the chuck is fixed, the pipe needs to be inserted into it, which not only increases the difficulty of operation, but also requires the operator to constantly adjust the position, thereby increasing labor costs. In addition, if the shape of the pipe is irregular, the chuck needs to open a larger gap to accommodate the pipe, which not only increases the ineffective stroke, but also reduces the welding efficiency. Utility Model Content

[0003] The utility model provides an open pipeline welding positioner for conveniently and quickly clamping pipelines, which solves the problems mentioned in the above background technology.

[0004] The technical solution of the utility model is achieved in this way:

[0006] A pair of driving wheels is arranged on one side of the fixed component close to the movable component, and one or a pair of driven wheels is arranged on one side of the movable component close to the fixed component.

[0007] Furthermore, a push rod structure is provided on the top of the support frame, and a piston end of the push rod structure passes through the top of the support frame and is connected to the top of the movable component via a floating joint.

[0008] Furthermore, a guide track is provided on the inner side of the support frame, and a slider which slides along the guide track is provided on the movable component.

[0009] Furthermore, it also includes a workbench, the bottom of the support frame is fixed to the top of the workbench, and a driving mechanism for driving the driving wheel is provided in the workbench.

[0010] Furthermore, the driving mechanism includes a servo motor fixed on the outside of the workbench, and the output end of the servo motor is provided with a driving wheel located in the workbench, and the driving wheel and the driving wheel are driven by a synchronous belt.

[0011] Furthermore, the driving mechanism also includes a traction wheel rotatably arranged in the fixed component, the traction wheel is located at the bottom between adjacent driving wheels and is connected to the synchronous belt transmission.

[0012] Furthermore, the fixing component is a plate-shaped member with a through-hole inside, and the through-hole accommodates and adapts to the driving wheel and the synchronous belt.

[0013] Furthermore, the synchronous belt is a toothed synchronous belt, the driving wheel and the active wheel are toothed wheels, and the toothed wheels and the toothed synchronous belt are meshed with each other.

[0014] Furthermore, the movable component is a plate-shaped member having a notch inside, and the notch accommodates and adapts to the driven wheel.

[0015] Furthermore, opposite sides of the fixed component and the movable component have openings.

[0016] Beneficial effects of the technical solution provided by this application:

[0017] The open pipe welding positioner, because the movable components slide directly along the support frame in a straight line, allows the operator to quickly clamp and release the pipe, significantly reducing the clamping time.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-2 An open pipeline welding positioner includes a fixed component 200 arranged on a support frame 300, and a movable component 400 arranged to slide linearly along the support frame 300; a pair of driving wheels 210 are provided on the side of the fixed component 200 close to the movable component 400, and one or a pair of driven wheels 410 are provided on the side of the movable component 400 close to the fixed component 200.

[0024] The support frame 300 serves as the basic structure of the entire welding positioner, providing stability and guidance. The support frame 300 is fixed on the welding workbench to provide a reference for the installation and movement of the fixed component 200 and the movable component 400. The fixed component 200, as a static component of the welding positioner, provides a fixed end point for clamping the pipeline. The fixed component 200 is installed on the support frame 300 and works in conjunction with the movable component 400 to clamp the pipeline with the relative movement of the movable component 400. The movable component 400 is responsible for sliding along the linear trajectory of the support frame 300 to achieve the clamping and release of the pipeline. The movable component 400 moves relative to the fixed component 200 to achieve rapid clamping and release of the pipeline. The driving wheel 210 is used to transmit power and drive the clamped pipeline to rotate after being driven. The driven wheel 410 cooperates with the driving wheel 210 to ensure the smooth rotation of the pipeline.

[0025] The linear sliding of the movable assembly 400 causes the position of the driven wheel 410 to change relative to the driving wheel 210, thereby clamping the pipeline. When the movable assembly 400 moves toward the fixed assembly 200, the driven wheel 410 clamps the pipeline under the drive of the driving wheel 210; when the movable assembly 400 moves away from the fixed assembly 200 along the sliding path, the driven wheel 410 releases the pipeline. The driving wheel 210 receives power and drives the driven wheel 410 to rotate, thereby driving the pipeline clamped on the movable assembly 400 to rotate. This rotation is very critical for different welding positions during the welding process.

[0026] In some embodiments, a push rod structure 500 is provided on the top of the support frame 300 , and a piston end of the push rod structure 500 passes through the top of the support frame 300 and is connected and fixed to the top of the movable component 400 via a floating joint.

[0027] The push rod structure 500 is usually used to realize linear drive, which pushes or pulls certain components in the welding positioner through the movement of the piston end. The push rod structure 500 includes but is not limited to hydraulic, pneumatic, electric, ball screw, and electromagnetic push rods. Different push rod structures have different movement speeds, which need to be selected according to the operating speed requirements of the welding positioner.

[0028] The push rod structure 500 provides a linear driving force through the linear movement of its piston end, and this driving force can directly act on the fixed component 200 to push or pull the movable component 400 to move along the guide path of the support frame 300. The fixing effect of the fixed component 200 combined with the linear drive of the push rod structure 500 can achieve precise control of the movable component 400. The support frame 300 provides a stable installation foundation for the push rod structure 500 and the fixed component 200, ensuring the structural stability and operational reliability of the entire welding positioner under the action of the push rod structure 500.

[0029] In some embodiments, a guide rail 310 is disposed on the inner side of the support frame 300 , and a slider 420 that slides along the guide rail 310 is disposed on the movable component 400 .

[0030] The guide rail 310 ensures that the movable assembly 400 slides smoothly and accurately along a specific path. The guide rail 310 is installed on the inner side of the support frame 300 and cooperates with the slider 420 on the movable assembly 400 to ensure the linear motion of the movable assembly 400. The slider 420 is a key component on the movable assembly 400. It slides along the guide rail 310 to achieve the linear motion of the movable assembly 400. The slider 420 is installed on the movable assembly 400 and cooperates with the guide rail 310 to ensure the accurate movement of the movable assembly 400 while reducing friction and wear.

[0031] Some embodiments further include a workbench 100 , wherein the bottom of the support frame 300 is fixed to the top of the workbench 100 , wherein a driving mechanism 600 for driving the driving wheel 210 to move is disposed in the workbench 100 .

[0032] The workbench 100 provides a stable basic platform for the welding positioner, ensuring the stability of the entire system and the reliability of operation. The top of the workbench 100 is provided with a fixing point for the support frame 300, and a built-in drive mechanism 600 is provided to provide a power source for the driving wheel 210. The drive mechanism 600 is a power-providing component used to drive the driving wheel 210 to rotate and realize the rotation of the pipeline. The drive mechanism 600 is installed in the workbench 100 and transmits power to the driving wheel 210 through mechanical, pneumatic or hydraulic transmission methods.

[0033] The driving mechanism 600 is installed in the workbench 100 and connected to the driving wheel 210 to transmit power to the driving wheel 210. The driving wheel 210 receives the power from the driving mechanism 600 and realizes the rotation of the pipeline by clamping the pipeline with the driven wheel 410.

[0034] In some embodiments, the driving mechanism 600 includes a servo motor 610 fixed outside the workbench 100, and the output end of the servo motor 610 is provided with a driving wheel 620 located in the workbench 100, and the driving wheel 620 and the driving wheel 210 are driven by a synchronous belt 630. The transmission method should include other similar types, including but not limited to a chain group.

[0035] The servo motor 610 is fixed on the outside of the workbench 100, and its output end is connected to the driving wheel 620, which transmits power to the driving wheel 210 through the synchronous belt 630 to achieve precise control of the rotation of the pipeline.

[0036] The driving wheel 620 is a wheel directly connected to the output end of the servo motor 610, and it transmits the rotational motion of the motor to the synchronous belt 630. The driving wheel 620 is located in the workbench 100, directly connected to the output end of the servo motor 610, and indirectly connected to the driving wheel 210 through the synchronous belt 630 to transmit the rotational power. The synchronous belt 630 connects the driving wheel 620 and the driving wheel 210 to transmit power between the two. The synchronous belt transmission allows a certain torque transmission, and at the same time can buffer and reduce vibration during the transmission process. As a transmission element, the synchronous belt transmits the rotational motion of the driving wheel 620 to the driving wheel 210. The driving wheel receives the power transmitted from the driving wheel 620 through the synchronous belt 630 and converts it into the rotational motion of the pipeline.

[0037] In some embodiments, the driving mechanism 600 further includes a traction wheel 640 rotatably disposed in the fixing assembly 200 . The traction wheel 640 is located at the bottom between adjacent driving wheels 620 and is drivingly connected to the synchronous belt 630 .

[0038] The main function of the traction wheel 640 is to change the direction of the synchronous belt 630, ensure that the synchronous belt can correctly transmit power between the two driving wheels 210, and provide sufficient clamping space for the pipeline. The traction wheel 640 is located at the bottom between the two driving wheels 210 and is connected to the driving wheels 210 through the synchronous belt 630. The setting of the traction wheel 640 allows the synchronous belt to go around the traction wheel 640 after passing the first driving wheel, and then turn up and go around the second driving wheel, forming a continuous transmission path.

[0039] The setting of the traction wheel 640 allows the synchronous belt 630 to transmit power in a non-horizontal manner between the two driving wheels 210, while maintaining the gap between the driving wheels 210, providing a clamping space for the pipeline. The use of the traction wheel 640 improves the adaptability of the welding positioner to pipelines of different diameters, because the gap between the driving wheels 210 can accommodate pipelines of different sizes.

[0040] In some embodiments, the fixing assembly 200 is a plate-shaped member with a through-hole inside, and the through-hole accommodates and adapts to the driving wheel 210 and the synchronous belt 630 .

[0041] The through-hole is a space area inside the fixed component 200, which is specially used to accommodate the driving wheel 210 and the synchronous belt 630. The design of the through-hole ensures that the driving wheel 210 and the synchronous belt 630 can be stably installed in the fixed component 200 while maintaining the correct working position and spacing.

[0042] In some embodiments, the synchronous belt 630 is a toothed synchronous belt, the driving wheel 620 and the driving wheel 210 are toothed wheels, and the toothed wheels and the toothed synchronous belt are meshed with each other.

[0043] The driving wheel 620 is a toothed wheel, and its tooth grooves are precisely meshed with the toothed protrusions of the toothed synchronous belt 630, thereby achieving effective power transmission. The driving wheel 210 is also a toothed wheel, which is meshed with the toothed protrusions of the toothed synchronous belt 630, ensuring stable power transmission from the driving wheel 620 to the driving wheel 210. The toothed synchronous belt is a synchronous belt 630 with toothed protrusions, which can precisely mesh with the tooth grooves of the toothed wheel, providing more reliable transmission and better torque transmission capabilities. The toothed synchronous belt 630 not only transmits power, but also ensures that the rotation speed can be maintained at a stable level under different loads through the meshing of the toothed protrusions with the toothed wheel to prevent slipping.

[0044] In some embodiments, the movable component 400 is a plate-shaped member having a notch inside, and the notch accommodates and fits the driven wheel 410 .

[0045] The slot is a space inside the movable assembly 400, which is specifically used to accommodate and adapt the driven wheel 410. The design of the slot ensures that the driven wheel 410 can be stably installed in the movable assembly 400, and forms an effective transmission chain with the driving wheel 210 through the synchronous belt 630.

[0046] In some embodiments, opposite sides of the fixed component 200 and the movable component 400 have openings.

[0047] The opposite side of the fixed component 200 has an opening, and this design allows the outer contour of the pipeline to be accommodated inside, thereby achieving the clamping of the pipeline. The opposite side of the movable component 400 also has an opening, which cooperates with the opening of the fixed component 200 to accommodate the outer contour of the pipeline, so as to facilitate the clamping and rotation of the pipeline. The design of the openings on the opposite sides of the fixed component 200 and the movable component 400 enables the welding positioner to adapt to pipelines of different sizes and clamp the pipeline by adjusting the distance between the openings.

[0048] The driving wheel 210 is designed to be able to fine-tune its position or size to adapt to pipelines of different diameters, thereby improving the versatility and adaptability of the welding positioner. By fine-tuning the center distance between the driving wheel 210 and the driven wheel 410 or changing the diameter of the driving wheel, the clamping force and transmission efficiency of the pipeline can be optimized. The driving wheel 210 can be designed to be modular, allowing wheels of different sizes to be replaced or its position to be adjusted to adapt to pipelines of different diameters. A fine-tuning mechanism such as a screw jack, a gear system or other precision adjustment mechanism can be integrated to achieve precise position adjustment of the driving wheel 210.

[0049] A transmission box 700 is provided in the workbench 100, and the driving wheel 620 is located in the transmission box 700; a tensioning arm 710 is hinged on the side of the transmission box 700 away from the driving wheel 620, and a tensioning wheel 720 is rotatably provided at the end of the tensioning arm 710, and the outer side of the tensioning wheel 720 abuts against the outer side of the synchronous belt 630 and transmits; in addition, an adjusting screw 730 is threadedly provided on the side of the transmission box 700, and the end of the adjusting screw 730 is hinged to the tensioning arm 710 through a connecting rod.

[0050] One end of the tension arm 710 is hinged on the transmission box 700, and the other end is rotatably provided with a tension wheel 720. The tension of the synchronous belt 630 is changed by adjusting the angle of the tension arm 710. The tension wheel 720 is rotatably provided at the end of the tension arm 710 and abuts against the outside of the synchronous belt 630. The tension of the synchronous belt is adjusted by the rotation of the tension wheel 720. The adjusting screw 730 is threadedly provided on the side of the transmission box 700, and its end is hinged to the tension arm 710 through a connecting rod. The position of the tension arm 710 is adjusted by rotating the adjusting screw 730, thereby changing the tension of the synchronous belt.
