Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and more specifically, to a welding device for pre-embedded parts of civil curtain walls used in building engineering. Background Art

[0002] The common form of embedded parts for civil engineering curtain walls is composed of anchor plates welded with anchor bars. Anchor plates and anchor bars are pre-reserved in the structure and can be used to connect structural members. They can also be used as connectors for later fixing processes. The early practice was to bend the steel bars and weld them directly to the anchor plates. Now the basic method is to drill holes in the anchor plates and then use plug welding.

[0003] The welding path in the current plug welding operation is as follows Fig.12 As shown, welding starts from point A, then passes through points B, C, and D to point E close to point A. However, in order to ensure that the welding material is in full contact with the inner wall of the anchor plate welding hole, welding will return to a position close to point A (point E) after starting from point A, and then move to the middle to point F, and so on, until the weld is filled. When welding from point E to point F, due to the large change in the angle of the welding path, the welding pool at point E is in a molten state. When the molten pool cools, shrinkage stress is generated, and tensile stress is applied to the molten pool close to point A, causing microcracks between points E and A. Under a certain pressure, the cracks expand, which can easily cause problems of cold welding. Even during transportation, the anchor bar may fall off the anchor plate. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Refer to the instruction manual Figure 1-Figure 11 A welding device for embedded parts of civil curtain walls used in construction projects includes a welding gun 1 and a driving assembly 2 for driving the welding gun 1 to move, and also includes: a retaining frame 3, the retaining frame 3 is used to install an anchor plate 100 and an anchor bar 200; a driving assembly 2, the driving assembly 2 is used to drive the relative movement of the welding gun 1 and the retaining frame 3 on the X-axis and the Y-axis; a Z-axis driving component 6, the Z-axis driving component 6 is used to drive the relative movement of the welding gun 1 and the retaining frame 3 on the Z-axis; the upper end of the anchor bar 200 is inserted into the welding hole 101 of the anchor plate 100, and the welding gun 1 performs plug welding on the anchor plate 100 and the anchor bar 200 until the welding hole 101 is filled, and the welding path is a spiral line 300.

[0034] Welding path such as Fig.11 The spiral line 300 shown in the figure is welded by making the welding gun 1 weld along the welding path of the spiral line 300. The welding path is continuous and smooth without sudden angle changes, thereby avoiding the problem of micro cracks caused by shrinkage stress due to large angle changes in the welding path.

[0035] Furthermore, the welding gun 1 is moved outward along the spiral line 300 from the middle end point of the spiral line 300 to weld the anchor plate 100 and the anchor bar 200. If the welding gun 1 is moved outward along the spiral line 300 from the end point outside the spiral line 300 as the starting point, when welding to the middle end point, the surrounding of the middle end point will cool first, so tensile stress will be generated on the molten pool at the middle end point, making it easy for micro cracks to appear at the middle end point. Therefore, it is best for the welding gun 1 to move outward along the spiral line 300 from the middle end point of the spiral line 300 to weld.

[0036] Furthermore, if Fig. 9 As shown, a grinding component 4 is also provided, and the grinding component 4 is at least used to grind the end of the welding path. Since the welding is performed along the path of the spiral line 300, in order to ensure that the welding of the end of the welding path with the anchor plate 100 does not cause a cold weld, the welding path needs to be completed, so solder accumulation is likely to occur at the end of the welding path, and this position can be polished by the grinding component 4. The welding device provided in this embodiment can be used for on-site welding. Due to the complex on-site environment and the large amount of dust and impurities, metal splashing and forming particles are likely to occur, so these splashing metal particles can also be polished by the grinding component 4.

[0037] In the above, the welding can be performed by plug welding using gas shielded welding, and the welding hole 101 can be filled with welding wire.

[0038] In this embodiment, the welding gun 1 is installed on the housing 11, and at least three laser emitters 5 that are not in the same straight line are installed in the circumferential direction of the outer side of the housing 11. The light emitted by the laser emitter 5 forms a point on the anchor plate 100. The circle uniquely determined by these points is basically equal to the size of the welding hole 101 of the anchor plate 100, wherein the laser emitter 5 is a visible light emitter. Figure 8 Three laser emitters 5 are provided. Before welding, the position of the center of the welding hole 101 needs to be found. The welding gun 1 can be moved to the position of the welding hole 101 by manual control so that the visible light emitted by the three laser emitters 5 can be simultaneously irradiated on the edge of the welding hole 101. The three points determine a circle, and the welding gun 1 is located at the center of the circle.

[0039] In addition to the above-mentioned method for finding the center position of the welding hole 101, the following method can also be adopted, that is, the welding gun 1 is installed on the shell 11, and at least three laser emitters 5 that are not in the same straight line are installed in the circumferential direction of the outer side of the shell 11. The laser emitter 5 is driven by a linear drive module 51 to move away from or close to the shell 11, wherein the laser emitter 5 is an infrared light emitter. By inputting the coordinates of the welding hole 101 in the drawing into the controller of the device, the welding gun 1 is controlled to automatically move to the position of the welding hole 101. However, due to the processing of the welding hole 101, the error may be large, so the welding gun 1 can only move to the approximate position of the welding hole 101, and then the laser emitter 5 emits infrared light to the anchor plate 100, the linear drive module 51 drives the laser emitter 5 to move, and the infrared receiver receives the infrared light. When the reflected light receiving time changes significantly, it can be determined that the infrared light has moved to the edge of the welding hole 101 (because there is a step between the upper surface of the anchor plate 100 and the welding hole 101). When the three beams of infrared light are all moved to the edge of the welding hole 101, the positions of the three laser emitters 5 at this time can be detected, and then the determined center coordinates are calculated, and the welding gun 1 is moved to this position for welding.

[0040] In this embodiment, if Figure 6-Figure 7 As shown, the retainer 3 includes a mounting plate 31, and a support plate 32 is provided on both sides of the mounting plate 31. The two support plates 32 are L-shaped plates arranged face to face, and are used to support the anchor plate 100 together. A positioning hole 33 for positioning the anchor bar 200 is provided on the upper surface of the mounting plate 31. Before welding, the anchor bar 200 is inserted into the positioning hole 33, and then the welding hole 101 is placed on the support plate 32, so that the upper end of the anchor bar 200 is inserted into the welding hole 101, and then welding can be performed. After welding is completed, it can be taken out upward.

[0041] In this embodiment, if Figure 3 As shown, the driving assembly 2 includes a Y-axis driving component 21 for driving the welding gun 1 to move along the Y-axis and an X-axis driving component 22 for driving the welding gun 1 to move along the X-axis. The welding gun 1 is mounted on the Y-axis driving component 21 through the housing 11, and the Y-axis driving component 21 is mounted on the X-axis driving component 22. Both the Y-axis driving component 21 and the X-axis driving component 22 can be driven by a guide rail plus a synchronous belt transmission mechanism, or can also be driven by a screw nut mechanism. When welding, the Y-axis driving component 21 and the X-axis driving component 22 can make the welding gun 1 walk out of the welding path of the spiral line 300.

[0042] In this embodiment, if Figure 4 As shown, the Z-axis driving component 6 includes a guide rail 61 arranged along the Z-axis, a base plate 62 installed on the guide rail 61, and a screw nut driving mechanism 63 for driving the base plate 62 to move along the guide rail 61, and the holder 3 is installed on the base plate 62. Before welding, the Z-axis driving component 6 can drive the holder 3 to move to the lowest point to install the anchor plate 100 and the anchor bar 200. During welding, the Z-axis driving component 6 can drive the holder 3 to move upward to facilitate welding.

[0043] In this embodiment, if Fig. 9 As shown, the grinding assembly 4 includes a fixed seat 41, a rocker arm 42 and a swing arm 43 which are rotatably mounted in sequence, the fixed seat 41 is fixedly mounted on the frame 10, and a grinder 44 is mounted at the front end of the swing arm 43. The rocker arm 42 and the swing arm 43 can be manually pulled to move the grinder 44 to a suitable position for grinding. Furthermore, the rocker arm 42 and the swing arm 43 are both driven to rotate by a motor, so that the grinding operation can be automatically performed through program control.

[0044] In specific operation, firstly, the spiral line 300 and the anchor plate 100 are installed on the holder 3, and then the welding gun 1 is positioned at the center of the welding hole 101. Then, the holder 3 is driven upward by the Z-axis driving component 6, and the welding operation can be performed. During the welding process, the driving component 2 controls the welding gun 1 to follow the welding path of the spiral line 300. After all the welding holes 101 are welded, the Z-axis driving component 6 controls the holder 3 to move downward, and then the grinding component 4 can be used to grind the plug welding position, especially the end of the welding path where solder accumulation is easy to occur.

[0045] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
