Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a rotary welding tooling. Background Art

[0002] Sleeves are commonly used in steel frame structures. Some sleeves seal the ends of pipes, such as those used to seal the ends of grouting pipes. Traditional sleeves are manufactured by lathing after cutting round pipes. For sleeves with welded short rods, end caps must be welded after lathing.

[0003] In the traditional welding process, multiple welding spots are formed on the end cap corresponding to the circular holes at the end of the sleeve. During the welding process, in order to ensure a tight weld between the sleeve and the end cap and avoid cold welds, a corresponding downward pressure structure is required to press down and fix the welding end surface of the end cap. The traditional welding method generally presses down the end cap by the downward pressure structure, and welds by the movement of the welding structure. In this method, the installation structure of the welding device has poor versatility, and the traditional welding tooling is mostly a fixed structure, which cannot complete the automatic switching of the welding point position. There is a certain risk of interference between the welding device and the downward pressure structure during movement. Utility Model Content

Obviously, the embodiments described 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 making creative efforts shall fall within the scope of protection of the present invention.

[0043] Sleeves are commonly used in steel frame structures. Some sleeves seal the ends of pipes, such as those used to seal the ends of grouting pipes. Traditional sleeves are manufactured by lathing after cutting round pipes. For sleeves with welded short rods, end caps must be welded after lathing.

[0044] In the traditional welding process, multiple welding spots are formed on the end cap corresponding to the circular holes at the end of the sleeve. During the welding process, in order to ensure a tight weld between the sleeve and the end cap and avoid cold welds, a corresponding downward pressure structure is required to press down and fix the welding end surface of the end cap. The traditional welding method generally presses down the end cap by the downward pressure structure, and welds by the movement of the welding structure. In this method, the installation structure of the welding device has poor versatility, and the traditional welding tooling is mostly a fixed structure, which cannot complete the automatic switching of the welding point position. There is a certain risk of interference between the welding device and the downward pressure structure during movement.

[0045] The present invention proposes a rotary welding tool 100 for solving the above problems.

[0046] See also Figures 1 to 6In one embodiment of the present invention, the rotary welding fixture 100 was initially designed to meet the welding operation of the cover plate at the end of the sleeve. In the traditional welding process, because multiple welding points need to be formed on the cover plate corresponding to the circular holes at the end of the sleeve, during the welding process, the sleeve is generally fixed first, and then the cover plate is placed on one end of the sleeve. Then, the output end of the welding device is used to make a circular motion on the cover plate, and then the sleeve and cover plates are welded. This welding operation generally has the following problems: if the welding device is integrated into the motion structure, and the motion structure drives the welding device to make a circular motion for welding, this method generally requires the design of a corresponding connecting structure to connect and fix the two. This connecting and fixing structure generally has a certain degree of specificity. When the position of the welding point changes, it is often not universal and has poor adaptability. If a corresponding adjustment structure is used to install the welding device, it will undoubtedly greatly increase the structural cost. In addition, to ensure a tight weld between the sleeve and the cover plate and avoid cold welds, a corresponding downward pressing structure is required to press down and secure the weld end surface of the cover plate. If the welding device is moved during welding, there is a certain risk of interference between the welding device and the downward pressing structure. Taking the above issues into consideration, in this embodiment, the fixing and movement of the sleeve are all set on the base 1, that is, on the fixed structure, so that the welding device can only perform the single welding work, thereby simplifying the tooling of the welding device as much as possible and avoiding the interference between the welding device and the fixing device during movement. Specifically, the rotating part 2 in the rotating fixing device can fix one end of the sleeve part and can drive the sleeve part to rotate around its axis, so as to meet the needs of continuous welding point switching. The downward pressing fixing structure mainly includes an adjusting part 5 and an ejector part 8. When pressing down and fixing, the adjusting part 5 drives the ejector part 8 to move, so that the downward end of the ejector part 8 presses against the center position of the cover plate part. The ejector part 8 can provide a certain downward pressure to maintain a stable downward pressure between the cover plate part and the end of the sleeve part, thereby avoiding the occurrence of cold welding as much as possible. The ejector part 8 is rotatably installed on the adjusting part 5. During the stable downward pressing process of the ejector part 8, it can rotate simultaneously with the rotation of the cover plate part, thereby avoiding the problem that the force between the ejector part 8 and the cover plate part is large, thereby affecting the rotational movement of the sleeve part. Therefore, through the setting of the above structure, the problems existing in the actual welding process can be effectively solved, and the structure is relatively simple and the feasibility is good.

[0047] In addition, it can be imagined that the relevant structures in the above embodiments are not only suitable for welding the end cover of the sleeve part, but other related structures to be welded that can use the central axis as the rotation axis to switch the welding point can also be welded through the above welding structure.

[0048] Among them, the downward pressing and fixing structure also includes an installation structure 6, which is mainly used to install the ejector part 8 and can adjust the position of the ejector part 8 within a certain range so that one end of the ejector part 8 can be pressed down on the rotation center position of the cover part. 61 and the second mounting block 62 are connected to each other.

[0049] The second mounting block 62 has a guide groove 623 at one end corresponding to the second fixing hole 621, and one end of the first mounting block 61 is located inside the guide groove 623. When fine-tuning the position of the second mounting block 62, the second mounting block 62 is guided within the guide groove 623, thereby ensuring the stability of the relative position of the second mounting block 62 to the first mounting block 61 and making the adjustment process more convenient.

[0050] A first bearing member 7 is provided on the inner side of the mounting hole 622, and the mounting seat 81 in the ejector member 8 is mounted on the inner ring of the first bearing member 7. The contact and downward pressure structure is provided as a screw member 82. It should be noted that the relevant structure in this embodiment should take into account the rotation direction of the rotating part 2, because the screw member 82 in this embodiment is mounted in the threaded hole in the mounting seat 81. When the lower end of the screw member 82 contacts the cover plate member, if the screw member 82 is to provide sufficient downward pressure to press down one end of the cover plate member during the rotation of the rotating part 2, then the rotating part 2 will be in a state of contact with the cover plate member. During the rotation of the movable sleeve member and the cover member, the screw member 82 will tend to move downward in the vertical direction on the mounting seat 81, so the rotation direction of the rotating part 2 must correspond to the thread rotation direction of the screw member 82, that is, when the rotating part 2 drives the cover member to rotate, the screw member 82 in close contact with the cover member must first move downward for a distance, thereby fully pressing down the cover member. After being fully pressed down, due to the large contact force, no relative movement is generated between the screw member 82 and the threaded hole of the mounting seat 81, and the screw member 82 rotates on the inner ring portion of the second bearing.

[0051] Therefore, the arrangement of the above structure not only drives the screw member 82 to press down and fix in the vertical direction through the adjusting member 5, but also combines the downward force provided by the screw member 82 itself under the drive of the cover member during the fixing process. Compared with the traditional downward pressing fixing structure, its fixing effect is better.

[0052] The adjusting member includes a vertically mounted cylinder member 51 and a first motor 52. The cylinder member 51 drives the first motor 52 to move in the vertical direction, thereby adjusting the vertical position of the screw member 82. The first motor 52 can drive the screw member 82 to rotate, thereby adjusting the position of the screw member 82 on the horizontal plane.

[0053] When the rotating part 2 is working, the second motor 23 inside it drives the rotating mounting part 22 to rotate. The pneumatic chuck 21 is installed on the rotating mounting part 22, so that during actual use, it rotates on the base 1 along with the rotating mounting part 22. The pneumatic chuck 21 is an existing structure and will not be described in detail here. In this embodiment, the multiple output ends of the pneumatic chuck 21 are provided with a clamping claw structure, and the clamping claw structure is arranged corresponding to the arc-shaped side wall of the sleeve member. When fixing, one end of the sleeve member is placed on the pneumatic chuck 21 for fixing, and then the cover member is placed on one end of the sleeve member. After the cover member is fixed by the relevant structure in the above embodiment, it is driven by the second motor 23, thereby driving the material to be welded to rotate, and cooperating with the corresponding welding device for welding.

[0054] The rotating mounting member 22 includes a second bearing member 221 and a mounting sleeve 223. The second bearing member 221 is mounted on the upper end surface of the base 1. A flange ring 224 is sleeved on the outer peripheral wall of the mounting sleeve 223, and the mounting sleeve 223 is mounted on the outer ring of the second bearing member 221 through the flange ring 224. When the second motor 23 is working, the pneumatic chuck 21 is driven to rotate simultaneously through the mounting sleeve 223.

[0055] A first gear 3 is provided on the output shaft of the second motor 23, and a second gear 4 is fixedly connected to the outer ring of the second bearing 221. The first gear 3 meshes with the second gear 4, and the flange ring 224 is fixedly connected to the second gear 4 via bolts. When the second motor 23 is operating, the first gear 3 and the second gear 4 mesh with each other and drive the mounting sleeve 223 to rotate synchronously via the flange ring 224. In this embodiment, gears are used as the transmission structure because the speed ratio can be set according to actual conditions. In actual applications, they can be replaced according to actual production materials.

[0056] The base 1 includes an electrical box structure 11, within which the corresponding electrical control structure can be placed. A mounting slot 12 is provided on the upper end surface of the electrical box structure 11. A mounting plate 13 is provided on the electrical box structure 11 corresponding to the mounting slot 12. The second motor 23 and the second bearing 221 are both mounted on the mounting plate 13. In actual operation, the mounting plate 13 is detachably fixed, so during installation, the relevant structures can be mounted on the mounting plate 13 before being mounted in the mounting slot 12.

[0057] At the same time, a protective shell 15 is provided on the mounting plate 13 corresponding to the first gear 3, the second gear 4 and the outer side of the flange ring 224. The protective shell 15 is used to isolate the relevant transmission structure, thereby improving the safety of the entire device during use.

[0058] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
