[0013] In the following description, a large number of specific details are given in order to provide a more complete understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0014] Embodiment one:

[0015] The modular positioning structure for the front riser of the frame assembly tooling proposed in this embodiment includes a platform 1 with a predetermined working size and load-bearing space. The working surface of the platform 1 is provided with a base 2 of a predetermined working size, which can perform corresponding support and limiting operations. It also includes a rocker arm rotating bracket 3 with a predetermined working length and supporting force, placed on the working surface of the base 2; a cylinder 4 with a predetermined working size connected to the rocker arm rotating bracket 3; a front tube clamping structure with one end connected to the cylinder 4 and the other end connected to the rocker arm rotating bracket 3; and a front riser lower positioning plate 9 placed on the working surface of the base 2, with a predetermined working distance between it and the rocker arm rotating bracket 3. The front tube clamping structure includes an adapter arm 5 and a clamping support arm 6. The clamping support arm 6 is connected to the rocker arm rotating bracket 3 via a bearing and a rotating shaft, and has a predetermined working length and supporting force. One end of the adapter arm 5 is connected to the clamping support arm 6, and the other end is connected to the cylinder 4, which can perform corresponding connection and limiting operations. In a further preferred embodiment, the base 2 and the platform 1 are connected and fixed by M12 bolts and limit pins.

[0016] Example 2:

[0017] Based on Embodiment 1, connecting plates 7 are connected to the left and right sides of the cylinder 4 in the working direction. Each connecting plate 7 has a predetermined working length, one end connected to the cylinder 4, and the other end connected to the base 2. Multiple connecting plates 7 are present. The working surface of the clamping support arm 6 is provided with a front upright upper positioning plate 8, and the working position of the front upright upper positioning plate 8 corresponds to the front upright lower positioning plate 9. A cylinder 4 connecting bracket is provided outside the cylinder 4 and is connected to the connecting plates 7 by bolts. In a further preferred embodiment, there are at least two connecting plates 7, which are fixed to the working surface of the base 2 by M8 bolts.

[0018] Based on the above embodiments, the specific implementation of this utility model is as follows: The base 2 is connected and fixed to the platform 1 by the base plate at the lower end of the working direction using M12 bolts and limit pins. The cylinder 4 is connected and fixed to the base 2 by the connecting plates 7 on both sides using M8 bolts. The front tube clamping structure is connected to the cylinder 4 by the adapter arm 5 using connecting pins and cotter pins. The front tube clamping structure is also connected to the rocker arm rotating bracket 3 by bearings and rotating shafts. The rocker arm rotating bracket 3 is connected and fixed to the base 2 by M8 bolts and limit pins. Finally, the front tube lower positioning M8 bolts and limit pins are fixed to the base 2.

[0019] The perfect combination of base 2, connecting plate 7, cylinder 4, rocker arm rotating bracket 3, front tube clamping structure, and front tube lower positioning forms a complete frame assembly tooling front riser modular positioning structure. This positioning structure can achieve rapid clamping and precise positioning of the front riser.

[0020] When the frame assembly welding begins, the front riser is first positioned at the lower positioning plate 9 for limiting. Then, the pneumatic clamping switch is turned on, and cylinder 4 extends accordingly, rotating the front riser clamping structure around the rocker arm rotating bracket 3 to clamp and position it. The tooling uses pneumatic clamping for convenient and quick operation, and the positioning plate ensures positioning accuracy. After the frame welding is completed, the pneumatic switch is turned off, cylinder 4 resets, and the front riser clamping structure opens. The welded frame assembly can then be removed and transported to the next process.

[0021] After modular production of the front riser positioning tooling for the chassis assembly, spare parts can be mass-produced and directly used when making chassis assembly welding tooling, reducing the front riser positioning production cycle and improving tooling production efficiency. If the positioning structure is worn and unusable, it does not need to be cut off for repair; the positioning structure is assembled and can be directly replaced using existing spare parts, making repairs simple and quick, without affecting the production efficiency of the chassis assembly welding line.

[0022] In a further preferred embodiment, the base 2 is provided with an auxiliary limiting plate on the side near the lower positioning plate 9 of the front riser, which can help support the pressing support arm 6 during operation.

[0023] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
