DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by persons of ordinary skill in the art without creative work shall fall within the scope of protection of this application.

[0015] See also Figure 1-3 The present application provides a technical solution: an adjustable positioning seat for cross-jointing welding of a split-type bridge, comprising a support pad 4, the upper surface of which is provided with a bottom support plate 3, the bottom support plate 3 is provided with a support column 7, and the upper end of the support column 7 is provided with a workpiece placement plate 2.

[0016] The support pad 4 is the foundational support structure for the entire positioning base, ensuring the entire device is securely placed on the ground. The support column 7 connects the bottom support plate 3 to the workpiece placement plate 2, providing vertical support from bottom to top, ensuring that the workpiece placement plate 2 remains level and stable. The support column 7 can be adjusted as needed to accommodate different workpiece heights. The support column 7 may also have an adjustment function, allowing the user to adjust the height as needed. The workpiece placement plate 2 is the platform for placing the workpiece to be welded, and it must be flat to ensure accurate workpiece placement.

[0017] The workpiece placement plate 2 is provided with a semi-horizontal groove and a semi-vertical groove, and the semi-horizontal groove and the semi-vertical groove are correspondingly provided with a horizontal adjustment seat and a vertical adjustment seat, and the horizontal adjustment seat and the vertical adjustment seat include a linear slide rail 10, a handwheel adjustment seat 8, a side frame plate 6 and a clamping cylinder 1. The side frame plate 6 is slidably provided on the linear slide rail 10, and a clamping cylinder 1 is provided on a side surface of the upper end of the side frame plate 6. The handwheel adjustment seat 8 is located between the linear slide rails 10, and the sleeve mounting seat on the handwheel adjustment seat 8 is socketed with the side frame plate 6.

[0018] The workpiece placement plate 2 is used to place the workpiece to be welded. The semi-horizontal groove and semi-vertical groove cooperate with the horizontal adjustment seat and the vertical adjustment seat to enable the workpiece to be accurately positioned.

[0019] The horizontal adjustment seat and the vertical adjustment seat ensure that the workpieces are in the correct relative position before welding through precise adjustment. The adjustment seat moves along the half horizontal groove and half vertical groove on the workpiece placement plate 2 to achieve fine adjustment of the workpiece position.

[0020] The linear slide rail 10 provides a track for the movement of the horizontal adjustment seat and the vertical adjustment seat, ensuring that the adjustment seat can move smoothly and accurately; the side frame plate 6 is a concave structure, and the bottom is connected to the slider on the linear slide rail 10, and can move freely on the slide rail; the clamping cylinder 1 is installed on one side of the upper end of the side frame plate 6, and is used to apply pressure to the workpiece to ensure that the workpiece does not move during welding.

[0021] The handwheel adjustment seat 8 is located between the linear slide rails 10, and the shaft sleeve mounting seat on the handwheel adjustment seat 8 is socketed with the side frame plate 6; the handwheel adjustment seat 8 includes a second shaft seat 12, a first shaft seat 9, a rotating shaft 13 and a rotating wheel 11. The rotating shaft 13 is driven by the rotation of the rotating wheel 11, and then the entire adjustment seat is driven to move along the linear slide rail 10, thereby adjusting the position of the clamping cylinder 1. After reaching the preset position, the clamping cylinder 1 extends to clamp the workpiece to ensure the clamping effect.

[0022] Furthermore, the side frame plate 6 is a concave structure, and its lower end is connected to the slider located on the linear slide rail.

[0023] The side frame plate 6 is concave. To better secure and install components like the clamping cylinder 1 and ensure a tight connection with the slider on the linear guide rail 10 for smooth movement, its two protruding ends extend out of the semi-horizontal and semi-vertical slots. The protruding ends are equipped with the clamping cylinder 1, which applies pressure to the workpiece, ensuring it remains stationary during welding.

[0024] Furthermore, the handwheel adjustment seat 8 includes a second shaft seat 12, a first shaft seat 9, a rotating shaft 13 and a rotating wheel 11. The first shaft seat 9 and the second shaft seat 12 are located at both ends of the upper surface, the rotating shaft 13 is located between the second shaft seat 12 and the first shaft seat 9, and the rotating wheel 11 is located at the end of the rotating shaft 13.

[0025] The first shaft seat 9 and the second shaft seat 12 are respectively located at both ends, for supporting the rotating shaft 13, ensuring the stability of the rotating shaft 13 and the accuracy of the linear motion; when the rotating wheel 11 rotates, the rotating shaft 13 will rotate accordingly, thereby driving the side frame plate 6 to move along the linear slide rail 10.

[0026] Furthermore, there are two lateral adjustment seats, which are arranged opposite to each other, and the vertical adjustment seat is arranged on one side of the workpiece placement plate 2.

[0027] Furthermore, a pressure plate cylinder 5 is provided on one side of the workpiece placement plate 2 , and the number of the pressure plate cylinders 5 is at least five, and the five pressure plate cylinders 5 are linearly evenly arranged.

[0028] The uniform pressure applied to the workpiece by the pressure plate cylinder 5 ensures that the workpiece remains stable during the welding process, thereby improving the welding quality. The use of the pressure plate cylinder 5 can quickly fix the workpiece, reduce preparation time, and improve production efficiency.

[0029] During use: place the support pad 4 on a stable ground to ensure that the entire positioning seat is stable, install the support column 7 to connect the bottom support plate 3 and the workpiece placement plate 2; fix the workpiece placement plate 2 on the top of the support column 7 to ensure that the workpiece placement plate 2 remains horizontal and stable; place the workpiece to be welded on the workpiece placement plate 2, and at this time use the horizontal adjustment seat and the vertical adjustment seat to accurately align the workpiece, and by rotating the rotating wheel 11 on the handwheel adjustment seat 8, drive the rotating shaft 13 to rotate, and then drive the side frame plate 6 to move smoothly along the linear slide rail 10, and finally adjust the position of the clamping cylinder 1 to position the workpiece laterally. Similarly, by rotating the rotating wheel 11 on the handwheel adjustment seat 8, adjust the position of the clamping cylinder 1 to position the workpiece vertically to ensure that the workpiece is completely aligned; when the workpiece position is adjusted into place, start the clamping cylinder 1 to apply pressure to the workpiece to ensure that the workpiece is fixed during the welding process; at the same time, start the pressure plate cylinder 5, and apply uniform pressure to the upper surface of the workpiece through at least five linearly arranged pressure plate cylinders 5 to ensure that the workpiece remains stable during the entire welding process, thereby completing the welding operation.

[0030] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
