Description

Technical Field

[0001] This utility model relates to the technical field of pipeline welding calibration devices, specifically a pipeline welding calibration device. Background Technology

[0002] Pipelines are components used to transport gases, liquids, or fluids containing solid particles. Due to limitations in production and processing space, and for ease of transportation, pipelines are generally manufactured in sections, so welding is required during installation.

[0003] While existing welding equipment allows users to hand-hold the welding torch to weld pipes, it lacks a mechanism for clamping pipes of different diameters and cannot detect the pipe alignment. This results in inaccurate cross-sectional alignment after pipe welding, reducing the welding precision required by the user. Therefore, we propose a pipe welding calibration device.

[0022] 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.

[0023] Please see Figure 1-5A pipe welding calibration device includes a workbench 1, a groove 2 on the top of the workbench 1, a rocker arm 3 on the inner wall of the groove 2, a lead screw 4 fixedly mounted on the outer wall of the rocker arm 3, a movable frame 5 threadedly connected to the outer wall of the lead screw 4, a motor 7 fixedly mounted on the top of the movable frame 5, a lifting groove 6 on the outer wall of the movable frame 5, a lead screw 12 fixedly mounted on the output shaft of the motor 7, a lifting seat 8 threadedly connected to the outer wall of the lead screw 12, a turntable 9 fixedly mounted on the outer wall of the lifting seat 8, a connecting pipe 10 rotatably connected to the outer wall of the turntable 9, a toothed groove 14 on the outer wall of the connecting pipe 10, and a motor fixedly mounted on the outer wall of the turntable 9. Motor 211 has a gear 13 fixedly mounted on its output shaft. The outer wall of the connecting pipe 10 is provided with an adjusting screw 16. One end of the adjusting screw 16 located inside the connecting pipe 10 is rotatably connected to a clamping plate 24. A limit rod 15 is fixedly mounted on the outer wall of the clamping plate 24. A return spring 17 is abutted against the outer wall of the clamping plate 24. A knob 18 is fixedly mounted on the end of the adjusting screw 16 away from the tooth groove 14. An infrared emitter 19 is also fixedly mounted on the outer wall of the turntable 9. An electromagnet 21 and a positioning plate 22 are fixedly mounted on the outer wall of the turntable 9. A tension spring 23 is provided on the outer wall of the positioning plate 22. The top of the tension spring 23 abuts against a rotating plate 20.

[0024] In the above structure, the setup of the workbench 1, slide 2, rocker arm 3, lead screw 4, moving frame 5, lifting groove 6, motor 7, lifting seat 8, turntable 9, and connecting pipe 10 allows the user to adjust the distance between the two clamping plates 24 by rotating the knob 18 during use. This facilitates clamping pipes of different diameters. Simultaneously, the operation of the motor 11 rotates the gear 13, causing the connecting pipe 10 to rotate along with the pipe. This allows the user to adjust the welding angle to perform welding operations at different positions on the pipe, thereby improving the applicability of the device and the user's welding efficiency.

[0025] In a preferred embodiment, an electromagnet is fixedly mounted on one end of the rotating plate 20 near the electromagnet 21, and both electromagnets 21 and 2 are attracted to each other when energized.

[0026] In the above structure, by setting up electromagnet 2 and electromagnet 1 21, the rotating plate 20 is rotated by energizing electromagnet 1 21 and electromagnet 2, thereby achieving the effect of locking gear 13 and connecting pipe 10, thus preventing the pipe from tilting or even shifting position during the welding process, thereby improving the stability of the pipe during the welding process.

[0027] In a preferred embodiment, the end of the rotating plate 20 away from the electromagnet 21 is attached to the inner wall of the tooth groove 14, and the connecting pipe 10 is fixedly connected to the turntable 9 through the rotating plate 20.

[0028] In the above structure, the adjustment of the pipe angle is automatically completed by the operation of the motor 11 through the set turntable 9 and rotating plate 20, so that the user does not need to manually adjust the pipe angle, thereby reducing the user's workload and further improving the user's work efficiency.

[0029] In a preferred embodiment, the outer wall of the movable frame 5 is slidably connected to the inner walls of the slide groove 2 and the lifting groove 6, respectively, and the lifting seat 8 is made of galvanized iron metal.

[0030] In the above structure, galvanized iron has the characteristics of hardness and wear resistance, which can effectively reduce the wear of the lifting seat 8 during operation, thereby extending the service life of the lifting seat 8. In addition, galvanized iron has the characteristic of low cost, which reduces the production and maintenance costs of the device.

[0031] In a preferred embodiment, there are two movable frames 5, and the two lifting slots 6 are symmetrically distributed along the top of the worktable 1.

[0032] In the above structure, the two workbenches 1 are provided so that during use, the two movable frames 5 can clamp a pipe respectively, which makes it easy for the user to use the movement of the movable frames 5 to fit the two pipes together. This makes it easy for the user to hold the welding gun to weld the pipes, thus ensuring the normal use of the device.

[0033] In a preferred embodiment, the outer wall of the connecting pipe 10 is provided with a through hole, and the inner wall of the through hole is threadedly connected to the outer wall of the adjusting screw 16.

[0034] In the above structure, the spacing between the two clamping plates 24 can be adjusted by rotating the adjusting screw 16 through the through hole, thereby achieving the effect of clamping pipes of different diameters, which facilitates user operation and improves the practicality of the device.

[0035] In a preferred embodiment, there are two clamping plates 24, and both clamping plates 24 are symmetrically distributed along the inner wall of the connecting pipe 10.

[0036] In the above structure, the two clamping plates 24 ensure that the pipe cannot detach from the clamping plates 24 during the welding process and can only be placed horizontally. The horizontality of the two pipes is detected by the cooperation of the infrared transmitter 19 and the infrared receiver, thereby ensuring that the center point of the two pipes is on the same horizontal line, thus improving the welding accuracy of the pipes for the user.

[0037] In a preferred embodiment, there are two turntables 9, and an infrared receiver is fixedly mounted on the outer wall of the other turntable 9. A controller is fixedly mounted on the outer wall of the worktable 1, and the controller is electrically connected to the infrared transmitter 19 and the infrared receiver respectively.

[0038] In the above structure, through the controller and infrared transmitter 19, the user can operate the various components of the device through the controller, thereby achieving the effect of automatically adjusting the pipe level and pipe welding position, simplifying the operation process of the device and further improving the automation of the device.

[0039] Working principle: First, the user can adjust the distance between the two clamping plates 24 by rotating the knob 18 to clamp pipes of different diameters. Then, the motor 7 rotates the lead screw 12, causing the lifting seat 8 to lift the turntable 9, connecting pipe 10, and pipe together, ensuring that the connection points of the two pipes are on the same horizontal line, avoiding errors in the connection, and thus improving the welding accuracy of the pipes. After adjusting the pipe angle and welding position, the electromagnets 21 and 2 are de-energized, causing the rotating plate 20 to rotate, so that the rotating plate 20 is pressed tightly against the inner wall of the tooth groove 14, achieving the effect of locking the gear 13, thereby improving the stability of the pipe during the welding process.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
