It is done by heating the metal material to its melting point and bringing the parts to be welded into contact with each other, allowing the molten metal material to re-solidify at the joint, thereby combining the parts into a relatively stable and reliable whole.

[0003] There is an existing bracket structure, which includes a chassis and two brackets welded on both sides of the chassis, four mounting column holes are arranged on the chassis, and the bracket includes a horizontal part and a vertical part, and the vertical part is bent downward at both ends of the horizontal part; in the existing welding process, it is necessary to insert the two vertical parts on the bracket into the mounting column holes on the chassis, and then one person supports the bracket, and the other person welds and fixes the vertical part to the mounting column holes.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: in the process of manually supporting the bracket for welding, manpower is required to maintain the support state of the bracket for a long time, and it is difficult to ensure the stability of the bracket during welding, and because the insertion degree of each vertical part in the mounting column hole is different, the horizontal part is warped or the heights of the two brackets are not flush, which makes it difficult to ensure the accuracy of welding positioning. Utility Model Content

[0005] In order to ensure the stability of the bracket during the welding process as much as possible and improve the accuracy of the bracket welding positioning, the present application provides a fixed bracket welding structure.

[0006] The present application provides a fixed bracket welding structure adopting the following technical solution:

[0007] A fixed bracket welding structure, which includes a supporting base column, a centering fixing piece is provided at the bottom of the supporting base column, and the centering fixing piece is used to fix the supporting base column in the center of the chassis to be welded; a positioning fixing plate is provided at the top of the supporting base column, and the positioning fixing plate is horizontally arranged, and a group of pressure codes are symmetrically and fixedly installed on the top of the positioning fixing plate, and the pressure codes are used to press the bracket to be welded, and two groups of positioning pins are fixedly and symmetrically arranged on the top of the positioning fixing plate.

[0008] By adopting the above technical solution, before welding the chassis and the bracket, the support base column is first placed on the chassis to be welded, and the support base column is fixed in the center of the chassis to be welded using a centering fixture, and then the two vertical parts of the bracket are inserted into the mounting column holes on one side of the chassis together, and the horizontal part of the bracket is placed on the positioning fixing plate, and it is ensured that the horizontal part is against the positioning pin, and then the horizontal part of the bracket is pressed against the positioning fixing plate using a pressure code, and finally the bracket and the chassis are welded as a whole; thereby ensuring the stability of the bracket during the welding process, ensuring that the insertion degree of all vertical parts in the mounting column holes is consistent, and improving the accuracy of the bracket welding positioning.

[0009] Preferably, the centering fixing part includes an outward extending sliding rod, a side hook plate, and a bottom hook plate. The outward extending sliding rod is slidably arranged in a group on both sides of the supporting base column. The side hook plate is fixed at one end of the outward extending sliding rod away from the supporting base column and is vertically arranged downward. The inner wall of the side hook plate can be abutted and fitted with the side wall of the chassis to be welded, and the bottom hook plate is fixed and vertically arranged at the inner bottom of the side hook plate.

[0010] By adopting the above technical solution, before welding the chassis and the bracket, the inner wall of the side hook plate is abutted and tightly attached to the side wall of the chassis to be welded, so as to avoid the overall twisting and deviation of the support base column on the chassis as much as possible, and ensure that the positioning pin is directly opposite to the horizontal part of the bracket to be welded, so as to preliminarily install the support base column on the chassis to be welded.

[0011] Preferably, a threaded hole is formed through the bottom hook plate, and a locking bolt is threadedly connected to the threaded hole.

[0012] By adopting the above technical solution, after the supporting base column is initially fixed on the chassis to be welded, the locking bolt is rotated so that the end of the locking bolt is abutted against the bottom wall of the chassis to be welded, and the chassis to be welded is clamped and locked between the extended slide rod and the locking bolt, thereby further improving the reliability of the connection between the extended slide rod and the chassis.

[0016] By adopting the above technical solution, without applying external force to the extended sliding rod, the torsion spring drives the central gear to rotate in the direction of pulling back the extended sliding rod, so that the extended sliding rod has a tendency to automatically pull back the side hook plate and the bottom hook plate, which helps to position the auxiliary support column on the base plate.

[0017] Preferably, a height adjustment component is provided on the supporting base column, and the height adjustment component is used to adjust the height position of the positioning fixing plate.

[0018] By adopting the above technical solution, after the welding between the chassis and the bracket is completed, the height adjustment component is used to adjust the height position of the positioning and fixing plate, and the height of the positioning and fixing plate is lowered, so that the structure of the present application can be removed as a whole from the chassis and bracket that have been welded.

The bottom end of the height adjustment rod is threadedly engaged with the supporting base column. A number of guide rods are vertically and fixedly arranged at the bottom of the positioning and fixing plate, and the guide rods are slidably connected to the supporting base column.

[0020] By adopting the above technical solution, when the height position of the positioning and fixing plate needs to be adjusted, the height adjusting rod is driven to rotate by the hand wheel to achieve the effect of turning the height adjusting rod more effortlessly. The bottom end of the height adjusting rod is engaged with the thread of the supporting base column to change the extension degree of the height adjusting rod at the top end of the supporting base column. The design of the guide rod helps to improve the guiding property of the vertical sliding between the positioning and fixing plate and the supporting base column, and improve the stability of the positioning and fixing plate during the height adjustment process.

[0021] Preferably, a rubber pad is fixedly provided on the upper surface of the positioning and fixing plate.

[0022] By adopting the above technical solution, the rubber pad increases the friction between the horizontal part and the positioning fixing plate, and helps to protect the horizontal part, and helps to prevent the pressure code from over-pressing the horizontal part and causing damage.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

The central gear 24 is also meshed with the racks 211 on the inner sides of the two extended sliding rods 21, ensuring that the extended lengths of the two extended sliding rods 21 on both sides of the support column 1 are consistent, thereby ensuring that the support column 1 is always located in the middle of the two extended sliding rods 21. A torsion spring 121 is arranged between the central gear 24 and the gear support shaft 12, one end of the torsion spring 121 is fixedly connected to the gear support shaft 12, and the other end of the torsion spring 121 is fixedly connected to the central gear 24, and the torsion spring 121 drives the central gear 24 to rotate in the direction of pulling back the extended sliding rod 21. When the outwardly extending slide bar 21 is not affected by external forces, the torsion spring 121 drives the central gear 24 to rotate in the direction of pulling back the outwardly extending slide bar 21 , which helps to position the auxiliary support column 1 on the base plate.

[0034] Reference Figure 3 The bottom hook plate 23 is fixed and vertically arranged at the bottom of the inner side of the side hook plate 22. A threaded hole 231 is formed through the bottom hook plate 23, and a locking bolt 2311 is threadedly connected to the threaded hole 231. The locking bolt 2311 is turned to clamp and lock the chassis to be welded between the extended sliding rod 21 and the locking bolt 2311, thereby further improving the reliability of the connection between the extended sliding rod 21 and the chassis.
