Description

Technical Field

[0001] This utility model relates to the field of gas box stud welding technology, specifically to tooling for gas box stud welding. Background Technology

[0002] Environmentally friendly gas ring main units are widely used in power systems, industrial production, and scientific research. The quality of their sheet metal parts has a significant impact on the equipment's performance. Traditional sheet metal welding processes mainly rely on manual operation, which is inefficient and makes it difficult to guarantee the consistency of weld quality.

[0003] Currently, in the welding of air box studs, there are many locations for the studs on the air box. The existing methods are basically to weld them onto the surface of the sheet metal using a template. In the welding of air box sheet metal studs, the positioning is mainly based on the dot positioning during sheet metal laser cutting. This process can only achieve single-sided bolt welding, and the positioning deviation can also occur due to the differences in sheet metal bending processes. There are also methods that use templates to imprint positioning on the surface of the sheet metal, but the sheet metal is heavy, and it is still difficult to flip it. Inconsistent placement of the sheet metal can also cause problems such as bolt misalignment and angle tilting during welding. When using L-shaped sheet metal, this method is prone to stud misalignment, angle tilting, and incomplete welding during the welding process, resulting in repeated rework. In addition, during the construction process, workers often have to bend over and manually flip the heavy sheet metal, which is extremely difficult.

[0004] A tooling for welding gas box studs was proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a tooling for welding gas box studs, so as to solve the current problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for welding gas box studs, including a base;

[0007] Two sets of omnidirectional wheels are symmetrically installed on the bottom of the base;

[0008] Also includes:

[0009] A support frame is fixedly installed on one side of the top of the base, and a mounting plate is fixedly installed on one side of the top of the support frame. A positioning plate is fixedly installed on the other side of the top of the support frame. A speed reducer is fixedly installed on one side of the mounting plate, and the output end of the speed reducer passes through the mounting plate and is fixedly installed with a rotating shaft. The rotating shaft is fixedly connected to the positioning plate.

[0010] A fixing sleeve is fixedly installed between the mounting plate and the positioning plate, and a positioning component is provided inside the lower part of the fixing sleeve. One end of the rotating shaft passes through the positioning plate and is fixedly installed with a tilting table.

[0011] The top side of the flipping table is provided with a template, and the top side of the template is symmetrically provided with a circular hole. Two sets of first quick clamps are symmetrically installed on both sides of the flipping table.

[0012] Preferably, uprights are symmetrically installed on one side of the top of the flipping table, and a second quick clamp is fixedly installed on the top of each of the two uprights.

[0013] Preferably, a crossbar is fixedly installed on one side of the inside of the flipping table, and support columns are symmetrically installed on the top of the crossbar.

[0014] Preferably, the positioning component includes a positioning rod slidably connected to the lower part of the fixed sleeve, and a plurality of positioning grooves are provided on the outer side of the rotating shaft, and the positioning rod is engaged with two positioning grooves.

[0015] Preferably, a telescopic spring is sleeved on the lower outer side of the positioning rod, and one end of the telescopic spring is fixedly connected to the fixed sleeve, and a fixed block is fixedly installed on the other end of the telescopic spring, and the fixed block is fixedly connected to the positioning rod.

[0016] Preferably, an installation rod is fixedly installed at the bottom end of the positioning rod, and a fixing rod is fixedly installed at the bottom of the fixing sleeve on one side of the positioning rod, and a rotating plate is rotatably connected to the bottom of the fixing rod.

[0017] Preferably, a limiting block is fixedly installed on one side of the bottom of the rotating plate, and a limiting groove is formed on one side of the top of the mounting rod, and the limiting block is engaged with the limiting groove.

[0018] Compared with existing technologies, the beneficial effects of this utility model are: the tooling for welding gas box studs, through different template positioning, can ensure the consistency and precision of welding. Clamping is convenient; a single person can use the overhead crane for rapid material loading and unloading. Flanging is easy, allowing for multi-angle welding, facilitating worker operation and improving production efficiency. The specific details are as follows:

[0019] 1. When welding studs onto L-shaped sheet metal, a single person uses an overhead crane to lift the workpiece to be welded onto the top of the tilting table. The workpiece is then placed on top of the tilting table, and the support column on the crossbar is used to support the L-shaped sheet metal. The sheet metal is then fixed by locking the first and second quick-clamps, which are widely used in existing technology. Afterward, the crane's lifting device can be released, and a hand-held template is placed on top of the workpiece, ensuring that the template and the two circular holes on the workpiece are concentric. The template has protrusions at the two circular holes for positioning with the workpiece. After positioning, spot welding can begin. Once one side is welded, the reducer can be controlled to rotate the shaft on the mounting plate and positioning plate, thereby rotating the tilting table and flipping the sheet metal for welding in other positions. After all welding is completed, the reducer is controlled to return to its original position for the unloading process. Using different templates for positioning ensures the consistency and precision of the welding. Easy to clamp, a single person can use the crane to quickly load and unload materials, easy to flip the edge, can perform multi-angle welding, convenient for workers to operate welding, and improve production efficiency;

[0020] 2. A positioning component is installed inside the lower part of the fixed sleeve. Before adjusting the angle of the tilting table, pushing down the mounting rod causes the positioning rod to slide on the fixed sleeve. After the positioning rod moves, it can be stretched by the tension spring through the fixed block, and the positioning rod can be disengaged from the positioning groove, so that the rotating shaft loses its limit. When the mounting rod moves down to the bottom of the rotating plate, rotating the rotating plate makes the limit block at the bottom of the rotating plate align with the limit groove at the top of the mounting rod. Then, the mounting rod is released, and the positioning rod moves up under the action of the tension spring. The limit block engages with the limit groove, thus positioning the positioning rod and preventing it from resetting. Then, the rotating shaft can be driven to rotate by the reducer, which can adjust the angle of the tilting table. After the tilting table angle is adjusted, the mounting rod can be pressed down to disengage the limit block from the limit groove. Rotating the rotating plate makes the rotating plate no longer obstruct the mounting rod. Then, the mounting rod is released, and the positioning rod resets under the action of the tension spring and engages with another positioning groove, thus positioning the rotating shaft. In this way, the rotating shaft can be positioned after rotation, avoiding damage to the rotating shaft and reducer due to excessive force during the welding of the plate studs, and improving the overall stability and reliability.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a tooling for welding gas box studs, including a base 1, with two sets of universal wheels 102 symmetrically installed on the bottom of the base 1, and further including: a support frame 101 fixedly installed on one side of the top of the base 1, and a mounting plate 103 fixedly installed on one side of the top of the support frame 101, and a positioning plate 104 fixedly installed on the other side of the top of the support frame 101, and a reducer 105 fixedly installed on one side of the mounting plate 103, with the output end of the reducer 105 passing through the mounting plate 103 and a rotating shaft 106 fixedly installed thereon, and the rotating shaft 106 and the positioning plate 104 being fixedly mounted thereon. Plate 104 is fixedly connected, wherein a fixing sleeve 107 is fixedly installed between mounting plate 103 and positioning plate 104, and a positioning component 2 is provided inside the lower part of the fixing sleeve 107. One end of the rotating shaft 106 passes through the positioning plate 104 and is fixedly installed with a tilting table 108. A template 109 is provided on one side of the top of the tilting table 108, and a circular hole is symmetrically opened through the top of the template 109. Two sets of first quick clamps 110 are symmetrically installed on both sides of the tilting table 108. By positioning with different templates 109, the consistency and accuracy of welding can be ensured. Clamping is convenient, and a single person can use the crane to quickly load and unload materials. The flanging is easy, and multi-angle welding can be performed, which is convenient for workers to operate and improves production efficiency.

[0029] A pair of uprights 111 are symmetrically installed on one side of the top of the flip table 108, and a second quick clamp 112 is fixedly installed on the top of each of the two uprights 111, which can further position the plate. A crossbar 113 is fixedly installed on one side of the inside of the flip table 108, and a support column 114 is symmetrically installed on the top of the crossbar 113, which can provide auxiliary support for the L-shaped plate. The positioning component 2 includes a positioning rod 201 slidably connected to the lower part of the fixed sleeve 107, and several positioning slots 202 are opened on the outer side of the rotating shaft 106. The positioning rod 201 is engaged with two positioning slots 202 to position the rotating shaft 106. A telescopic spring 203 is sleeved on the lower part of the outer side of the positioning rod 201, and one end of the telescopic spring 203 is connected to the fixed sleeve 107. The spring 203 is fixedly connected to a fixed block 204, which is fixedly installed on the other end. The fixed block 204 is fixedly connected to the positioning rod 201, so that the positioning rod 201 can automatically reset after moving. The bottom end of the positioning rod 201 is fixedly installed with an installation rod 205, and the bottom of the fixed sleeve 107 is fixedly installed with a fixed rod 206 on one side of the positioning rod 201. The bottom of the fixed rod 206 is rotatably connected with a rotating plate 207, so that the positioning rod 201 can be positioned after moving. A limit block 208 is fixedly installed on one side of the bottom of the rotating plate 207, and a limit groove 209 is opened on one side of the top of the installation rod 205. The limit block 208 and the limit groove 209 are engaged and connected, so that the installation rod 205 can be easily disengaged from the rotating plate 207.

[0030] Working principle: Before using the tooling for welding gas box studs, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, when welding studs onto L-shaped plates, a single person uses an overhead crane to lift the workpiece to be welded to the top of the tilting table 108. The workpiece is then placed on top of the tilting table 108, and the support column 114 on the crossbar 113 supports the L-shaped plate. The plate is then fixed by locking the first quick clamp 110 and the second quick clamp 112. The quick clamps, which are widely used in existing technology, fix the plate via a connecting rod. Afterwards, the overhead crane's lifting device can be released, and a handheld template 109 is placed on top of the workpiece, so that the template 109 and the workpiece... The two circular holes of the workpiece are concentric, and the two circular holes of the template 109 have protrusions for positioning with the workpiece. After positioning, spot welding can be performed. After welding on one side, the reducer 105 can be controlled to drive the rotating shaft 106 to rotate on the mounting plate 103 and the positioning plate 104, which in turn drives the tilting table 108 to rotate, allowing the plate to be flipped for welding in other positions. After all welding is completed, the reducer 105 is controlled to return to its original position for the unloading process. By using different templates 109 for positioning, the consistency and accuracy of welding can be ensured. Clamping is convenient, and a single person can use the overhead crane for rapid loading and unloading of materials. The edge flipping is easy, and multi-angle welding can be performed, making it convenient for workers to operate and improving production efficiency.

[0031] A positioning component 2 is installed inside the lower part of the fixed sleeve 107. Before the tilting table 108 adjusts the angle, the mounting rod 205 is pushed down to drive the positioning rod 201 to slide on the fixed sleeve 107. After the positioning rod 201 moves, it can stretch the telescopic spring 203 through the fixing block 204, and can also disengage the positioning rod 201 from the positioning groove 202, so that the rotating shaft 106 loses its limit. When the mounting rod 205 moves down to below the rotating plate 207, the rotating plate 207 is rotated so that the limiting block 208 at the bottom of the rotating plate 207 is aligned with the limiting groove 209 at the top of the mounting rod 205. Then the mounting rod 205 is released, and the positioning rod 201 moves up under the action of the telescopic spring 203. The limiting block 208 engages with the limiting groove 209, so that the positioning rod 201 is positioned. Positioning prevents the positioning rod 201 from resetting. Then, the reducer 105 drives the rotating shaft 106 to rotate, and the angle of the tilting table 108 can be adjusted. After the tilting table 108 is adjusted, the mounting rod 205 can be pressed down to disengage the limit block 208 from the limit groove 209. The rotating plate 207 is rotated so that it no longer obstructs the mounting rod 205. Then, the mounting rod 205 is released, and under the action of the telescopic spring 203, the positioning rod 201 resets and engages with another positioning groove 202, so that the rotating shaft 106 can be positioned. Thus, the rotating shaft 106 can be positioned after rotation, avoiding damage to the rotating shaft 106 and the reducer 105 due to excessive force during the welding of the plate studs, and improving the overall stability and reliability.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
