Description

Technical Field

[0001] The utility model relates to the technical field of teaching aids, in particular to a progressive pipeline welding learning movable rocker arm teaching aid. Background Art

[0002] Throughout the development of the machinery industry, new employee training has always been a top priority for a company's long-term growth. Ensuring that new employees master technical skills and adapt quickly to their roles is a key indicator of a company's vitality. In the welding industry, in particular, the quality of new employees' technical and skill acquisition directly impacts their performance.

[0003] Current welding teaching methods are basically the same when imparting theoretical knowledge, but there is no completely unified method for practical teaching. Often, after completing practical learning, new employees need a lot of time to adjust and integrate the knowledge when they enter the site. In the practical teaching of pipeline welding, the pipe-to-pipe connection is generally set to 45°, that is, in the welding teaching of pipeline 6G, the test piece is mostly placed directly at a 45° position for teaching. After that, the students will practice based on the technical points until the welded workpiece meets the corresponding quality standards.

[0004] Students practicing under this condition are not "practical" because at work, 45°6G represents a standard, not the direction of our work. There may be 25° welding positions, 35° welding positions, and 85° welding positions at work. In this case, the specific operation method of 45° is obviously not applicable. Therefore, the application proposed a step-by-step pipeline welding learning activity rocker arm teaching aid. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present invention provides a progressive pipeline welding learning movable rocker arm teaching aid, which solves the problem that in pipeline welding practical teaching, the pipe-to-pipe joint is generally set to 45°, but there is not only a 45° welding position at the workplace. In this case, the trainees practicing are not "practical".

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a progressive pipeline welding learning movable rocker arm teaching aid, comprising a support unit and a rocker arm unit, an angle adjustment unit is installed between the support unit and the rocker arm unit, and the angle adjustment unit includes:

[0007] A short tube bearing, with connecting plates installed at both ends of the short tube bearing, the connecting plates are fixedly connected to the top of the support unit, and the rocker unit is fixedly connected to the outer ring surface of the short tube bearing;

[0008] A rotating disk is fixedly sleeved on the end of the short tube bearing, and a positioning bolt is installed between the rotating disk and the connecting plate, and a scale needle is fixedly installed on the outer side of the rotating disk;

[0009] An arc-shaped scale is fixedly connected to the outer side of the connecting plate, the center of the arc-shaped scale coincides with the center of the rotating disk, and the needle of the scale needle points to the arc-shaped scale.

[0010] Preferably, the support unit includes:

[0011] A vertical pole, wherein a movable rod is slidably provided inside the vertical pole, and the top end of the movable rod extends upward and is fixedly connected to the connecting plate;

[0012] The first fixing hole and the second fixing hole are respectively opened through the outside of the vertical rod and the movable rod, and a fixing bolt is installed between the first fixing hole and the second fixing hole.

[0013] Preferably, a chassis is fixedly mounted on the bottom of the upright pole.

[0014] Preferably, the first fixing holes are provided in plurality, and the plurality of first fixing holes are arranged vertically and opened on the outer side of the vertical pole.

[0015] Preferably, an arcuate groove is provided on the outer side of the rotating disk, the positioning bolt is fixedly mounted on the outer side of the connecting plate, and the end of the positioning bolt passes through the arcuate groove and is threadedly connected with a nut, and the nut is tightly against the outer side of the rotating disk.

[0016] Preferably, the rocker arm unit comprises:

[0017] A cross arm, the end of which is fixedly connected to the outside of the short tube bearing;

[0018] A clamp is installed at the other end of the cross arm.

[0019] Preferably, a sleeve is fixedly mounted on the outer side of the clamp, and the sleeve is movably sleeved on the end of the cross arm, and a limiting bolt is provided between the sleeve and the end of the cross arm.

[0020] The utility model discloses a progressive pipeline welding learning movable rocker arm teaching aid, which has the following beneficial effects: when the progressive pipeline welding learning movable rocker arm teaching aid is in use, when the rocker arm unit rotates, the scale needle on the rotating disk also rotates concentrically with the short tube bearing, and indicates the specific angle on the arc scale, and then is fixed by the positioning bolts between the rotating disk and the connecting plate. In this way, when learning, the user can start with simple horizontal fixation, and continuously increase the angle according to the proficiency of the skill until the practice of 45° is met.

[0021] Compared to traditional fixed-style welding instruction, this tool offers a revolutionary advantage. Instead of a fixed learning process, new employees gradually become familiar with the technique, starting at 0° and progressing to 5°, 25°, and finally any other angle. After mastering the technical requirements of 45°, they will be able to operate any angle below 45° with absolute proficiency, fully adapting to the complex angles encountered in on-site pipeline welding. This allows learners to acquire skills more effectively and effectively. This gradual learning process allows for a phased and planned approach, with each student's progress reflected on the arc scale, making the technical skill learning process more granular and concrete.
