[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 , Figure 2 As shown, a three-dimensional perspective view of a common welding fixture for the front and rear beam assemblies is shown, wherein the welding fixture is used to weld welding screws 33 to the surfaces of the front beam 3 and the rear beam 31. The front beam 3 and the rear beam 31 have different lengths and curvatures due to their different installation and use positions, and a plurality of guide holes 32 are formed through the front beam 3 and the rear beam 31.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the implant welding tool includes a base plate 1, and a plurality of clamping assemblies 2 are detachably connected to the top of the base plate 1, and the plurality of clamping assemblies 2 are arranged at intervals with respect to the structural distribution of the front cross beam 3 and the rear cross beam 31; the clamping assembly 2 includes a cylinder 23, a fixed lower clamping block 27 and a movable upper clamping block 28, and the front cross beam 3 or the rear cross beam 31 passes through the gap between the lower clamping block 27 and the upper clamping block 28 before the implant welding process; during the implant welding process, the lower clamping block 27 remains stationary, and the cylinder 23 is used to drive the upper clamping block 28 to perform a top-down swinging motion until the front cross beam 3 or the rear cross beam 31 is clamped and remains stationary.

[0030] The clamping assembly 2 in the present technical solution can be flexibly disassembled at the top of the base plate 1, and multiple clamping assemblies 2 can be arranged in a customized position according to the structural distribution or orientation of the front beam 3 or the rear beam 31, thereby effectively reducing the space occupied by the tooling and increasing the scope of application of the tooling, and being able to perform limiter processing on various types of workpieces; and the steps of limiting and removing the workpiece by the clamping assembly 2 are relatively simple and convenient, and the positioning accuracy is also high.

[0031] As an example, Figure 1 As shown, a plurality of universal wheels 11 are installed at the bottom of the base plate 1, and the tooling can be quickly moved to other required positions through the universal wheels 11.

At this time, the workpiece can be placed above the lower clamping block 27 to keep the bottom of the workpiece close to the lower clamping block 27. Then, the output end of the cylinder 23 can be controlled to extend, and the swing arm 25 flips about the rotating block 24 at a certain angle and then resets until the upper clamping block 28 is close to the top of the workpiece, and the workpiece is clamped and limited.

[0033] As a further refinement of the above technical solution, the base 21 is an L-shaped structure consisting of a vertical section and a horizontal section, and a triangular reinforcing plate is connected between the vertical section and the horizontal section, thereby enhancing the structural strength of the base 21 and extending its service life.

[0034] As a further refinement of the above technical solution, a limit block 26 is also provided between the base plate 22 and the swing arm 25 for limiting the distance between the lower clamping block 27 and the upper clamping block 28. The bottom of the limit block 26 is fixedly connected to the top of the base plate 22, and the top of the limit block 26 is provided with a groove matching the cross-sectional size of the swing arm 25. When the swing arm 25 is rotated and embedded in the top groove of the limit block 26, the distance between the lower clamping block 27 and the upper clamping block 28 is the smallest, and the clamping force on the workpiece is also the largest.

[0035] As an example, the lower pressing block 27 and the upper pressing block 28 are both rubber blocks to avoid damaging the surface of the workpiece while pressing the workpiece.

[0036] In this solution, the base 21 is detachably connected to the bottom plate 1, and the base 21 is detachably connected to the base plate 22, and both are connected by screws, which facilitates changing the position of the base 21 or the base plate 22 to process different workpieces.

[0038] As an example, a rounded corner is formed on the top of the limiting post 53 to facilitate the limiting post 53 to be inserted into the guide hole 32 .

[0039] In this solution, the base plate 22 is detachably connected to the connecting block 1 51, and the connecting block 1 51 is detachably connected to the connecting block 2 52, and the connection method is to connect by screws, which is convenient for changing the position of the limit column 53 according to the structural distribution of the workpiece, so as to process different workpieces.

[0040] As a further refinement of the above technical solution, Figure 3 , Figure 4 , Figure 6As shown, a guide assembly 6 is installed on the surface of the substrate 22, and the guide assembly 6 includes a connecting rod 61, and the end of the connecting rod 61 is detachably connected to a connecting plate 62, and the extension length and extension angle of the connecting rod 61 match the position distribution of the implant welding screw 33 on the front crossbeam 3 or the rear crossbeam 31, and the top of the connecting plate 62 is detachably connected to a implant welding guide block 63, and the middle of the implant welding guide block 63 and the connecting plate 62 are penetrated by an operating hole 64, and the diameter of the operating hole 64 is larger than the diameter of the implant welding screw 33; according to the pre-set welding position of the implant welding screw 33, the guide assembly 6 is installed in place, so that after the workpiece is limited, the implant welding guide block 63 is just above the pre-welding position of the implant welding screw 33, and the implant welding screw 33 is inserted into the operating hole 64 until the bottom of the implant welding screw 33 abuts against the surface of the workpiece, and the implant welding gun can be used for welding at this time.

[0041] When the present solution is used to fix the workpiece, the clamping assembly 2 can be used to initially limit the position, and subsequently the limiting column 53 can be plugged into the guide hole 32 to further fix the position of the workpiece. After the fixation is completed, the implant welding screw 33 on the workpiece also matches the implant welding guide block 63, which is convenient for the user to weld the implant welding screw 33 on the workpiece. After the welding is completed, the upper clamping block 28 can be loosened to remove the entire workpiece, which is simple and quick.

[0042] The implant welding tool also includes a control box 4, which is installed on the top of the base plate 1. The control box 4 controls the air valve of the corresponding cylinder 23 through a PLC control system, thereby limiting the action position of the cylinder 23.

[0043] like Figure 7 , Figure 8 As shown, different forms of the limit assembly 5 or the guide assembly 6 after being assembled with the clamping assembly 2 are shown. This is based on the different structural distributions of the workpieces, so the installation position of the limit assembly 5 or the guide assembly 6 is designed specifically.
