AI Technical Summary
Existing weld leveling devices are difficult to control the leveling degree, which can lead to excessive leveling of the steel structure surface, resulting in dents or damage, affecting the aesthetics and potentially causing the steel structure to be scrapped.
The system employs a combination of a protective cover, a reference cover, and an internal threaded sleeve. By adjusting the position of the reference cover, the leveling disc is made flush with the weld surface, avoiding over-leveling. Combined with measuring the distance using a measuring ruler, the position of the reference cover is precisely adjusted to ensure the leveling effect.
This method avoids damage to the steel structure during the leveling process, maintains surface flatness, improves the accuracy and aesthetics of weld leveling, and prevents the steel structure from being scrapped.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, and in particular to a leveling device for steel structure welds. Background Technology
[0002] Steel structure welding refers to the connection of welds in steel structures. It mainly uses electric arc welding, which uses the high temperature generated by the electric arc to melt the metal of the welding rod or welding wire placed at the weld joint, thereby connecting the components together.
[0003] During the welding process, burrs are prone to appear at the weld seams of steel structures. Therefore, it is generally necessary to use relevant equipment to grind and smooth the weld seams afterward. Regarding this grinding and smoothing device, a search reveals, for example, a steel structure welding anti-burr device provided by patent publication number CN216608366U, which includes a base, a mounting frame fixedly connected to the top of the base, a hydraulic rod fixedly connected to the middle of the bottom end of the mounting frame, a fixed cover fixedly connected to the bottom end of the hydraulic rod, a grinding device inside the fixed cover, grooves carved at both ends of the fixed cover, a filter screen fixedly connected to the inner wall of the groove, connecting covers symmetrically arranged on both sides of the fixed cover, a connecting pipe connected to the end of the connecting cover away from the fixed cover, a fan connected to the other end of the connecting pipe, and a collection tray on both sides of the bottom end of the fixed cover. This allows for the grinding of the burrs at the weld seams of the steel structure using the smoothing tray, and the burrs to be sucked into the collection tray.
[0004] Based on the above search and analysis of existing technologies, it has been found that existing weld seam flash treatment devices similar to those disclosed above have difficulty controlling the degree of flattening during weld seam leveling and grinding. In particular, excessive flattening can cause depressions on the steel structure surface, affecting aesthetics and, in severe cases, rendering the steel structure unusable. Therefore, a steel structure weld seam leveling device is proposed to improve the above-mentioned problems. Utility Model Content

[0010] The reference mechanism is adjustablely mounted on the leveling arm to limit the movement of the protective cover.
[0011] As a further supplement to this solution, the reference mechanism includes a reference cover and an internal threaded sleeve. The internal threaded sleeve is threaded onto the outside of the leveling arm, and the reference cover is fixed to the lower end of the internal threaded sleeve. The lower end of the reference cover limits the movement of the protective cover.
[0012] As a further supplement to this solution, a measuring ruler is also included, which is used to measure the distance between the top surface of the protective cover and the plane where the weld is located.

Detailed Implementation
[0027] 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.
[0028] Example: Reference Figure 1-5 The illustrated steel structure weld smoothing device includes a base 1, a smoothing head 3, a protective cover 6, and a reference mechanism.
[0029] The leveling head 3 includes a mounting frame 301, a drive motor 302, and a leveling disc 303. The mounting frame 301 is fixed to the bottom end of the leveling arm 2, the drive motor 302 is mounted on the side end of the mounting frame 301, and the leveling disc 303 is coaxially fixed with the output shaft of the drive motor 302. The drive motor 302 drives the leveling disc 303 to rotate at high speed to level the weld 14.
[0030] The base 1 has a leveling arm 2 fixed at its lower end, a leveling head 3 installed at the lower end of the leveling arm 2, a protective cover 6 covering the outside of the leveling head 3 and fixedly sleeved on the outside of the leveling arm 2, a limiting ring 4 fixedly sleeved on the upper side of the protective cover 6 and fixedly sleeved on the outside of the leveling arm 2, and a compression spring 5 fixed between the limiting ring 4 and the protective cover 6.
[0031] During the process of leveling the weld 14 on the steel structure 13 using the leveling head 3, the protective cover 6 is always placed on the outside of the leveling head 3 and is in close contact with the surface of the steel structure 13, which can effectively prevent debris from flying during the leveling process.
[0032] The reference mechanism is adjustablely installed on the leveling arm 2 to limit the protective cover 6. Specifically, the reference mechanism includes a reference cover 7 and an internal threaded sleeve 8. The internal threaded sleeve 8 is threaded onto the outside of the leveling arm 2, and the reference cover 7 is fixed to the lower end of the internal threaded sleeve 8. The lower end of the reference cover 7 limits the protective cover 6.
[0033] Based on the above-mentioned matching arrangement of the reference cover 7 and the internal threaded sleeve 8, the position of the reference cover 7 can be adjusted according to the specific location of the weld 14 on the steel structure 13 during use.
[0034] like Figure 3 It is shown that when the weld 14 at the flat part of the steel structure 13 is leveled, the position of the reference cover 7 is adjusted in advance by rotating the internal thread sleeve 8 so that when the bottom surface of the leveling plate 303 is flush with the flat surface of the steel structure 13, the reference cover 7 abuts against the protective cover 6 to avoid the leveling plate 303 from over-leveling and causing damage to the steel structure 13.
[0035] like Figure 4 It is shown that when the weld 14 at the recess 15 of the steel structure 13 is leveled, the position of the reference cover 7 is adjusted in advance by rotating the internal thread sleeve 8 so that the bottom surface of the leveling plate 303 is flush with the surface of the recess 15 of the steel structure 13. The reference cover 7 abuts against the protective cover 6 to avoid the leveling plate 303 from over-leveling and causing damage to the steel structure 13.
[0036] like Figure 5 This shows that when leveling the weld 14 at the protrusion 16 of the steel structure 13, the position of the reference cover 7 is adjusted beforehand by rotating the internal threaded sleeve 8 so that the bottom surface of the leveling plate 303 is flush with the surface of the protrusion 16 of the steel structure 13. At this time, the reference cover 7 abuts against the protective cover 6 to prevent the leveling plate 303 from over-leveling and causing damage to the steel structure 13.
[0037] The steel structure weld smoothing device also includes a measuring ruler 9. A sliding hole 12 is provided on the protective cover 6 for the measuring ruler 9 to slide vertically. A limit block 10 is fixed to the end of the measuring ruler 9. An elastic connector 11 is fixed between the top of the measuring ruler 9 and the top surface of the protective cover 6. The measuring ruler 9 is used to measure the distance between the top surface of the protective cover 6 and the plane where the weld 14 is located, thereby facilitating the measurement of the thickness of the protrusion 16 or the recess 15, and thus facilitating the accurate adjustment of the position of the reference cover 7 based on the measured value.
[0038] like Figure 4 The diagram shows the leveling of the weld 14 at the recess 15 of the steel structure 13, as follows: Figure 3Using the position of the measuring ruler 9 relative to the top surface of the protective cover 6 as a reference, the depth of the recess 15 is measured by measuring the measuring ruler 9. The internal threaded sleeve 8 is rotated to adjust the position of the reference cover 7 upwards. The distance the reference cover 7 is adjusted upwards is the depth of the recess 15.
[0039] like Figure 5 The diagram shows that when the weld 14 at the protrusion 16 of the steel structure 13 is leveled, it is done in the same way as... Figure 3 Using the position of the measuring ruler 9 relative to the top surface of the protective cover 6 as a reference, the thickness of the protrusion 16 is measured by the measuring ruler 9. The internal threaded sleeve 8 is rotated to adjust the position of the reference cover 7 downwards. The downward adjustment distance of the reference cover 7 is the thickness of the protrusion 16.
[0040] The working principle of this utility model is as follows: Figure 3 It is shown that when the weld 14 at the flat part of the steel structure 13 is leveled, the position of the reference cover 7 is adjusted in advance by rotating the internal thread sleeve 8 so that when the bottom surface of the leveling plate 303 is flush with the flat surface of the steel structure 13, the reference cover 7 abuts against the protective cover 6 to avoid the leveling plate 303 from over-leveling and causing damage to the steel structure 13.
[0041] like Figure 4 The diagram shows the leveling of the weld 14 at the recess 15 of the steel structure 13, as follows: Figure 3 Using the position of the measuring ruler 9 relative to the top surface of the protective cover 6 as a reference, the depth of the recess 15 is measured by the measuring ruler 9. The internal threaded sleeve 8 is rotated to adjust the position of the reference cover 7 upward. The upward adjustment distance of the reference cover 7 is the depth of the recess 15. When the bottom surface of the leveling plate 303 is flush with the surface of the recess 15 of the steel structure 13, the reference cover 7 abuts against the protective cover 6 to avoid the leveling plate 303 from over-leveling and causing damage to the steel structure 13.
[0042] like Figure 5 The diagram shows that when the weld 14 at the protrusion 16 of the steel structure 13 is leveled, it is done in the same way as... Figure 3 Using the position of the measuring ruler 9 relative to the top surface of the protective cover 6 as a reference, the thickness of the protrusion 16 is measured by the measuring ruler 9. The internal threaded sleeve 8 is rotated to adjust the position of the reference cover 7 downward. The downward adjustment distance of the reference cover 7 is the thickness of the protrusion 16. When the bottom surface of the leveling plate 303 is flush with the surface of the protrusion 16 of the steel structure 13, the reference cover 7 abuts against the protective cover 6, thus preventing the leveling plate 303 from over-leveling and causing damage to the steel structure 13.
