[0003] Aerial work platforms come in various forms, including folding, straight-reaching, and hybrid types. Among these diverse models, the booms come in different forms, such as telescopic and folding, and the tie rods also vary in type. However, almost all booms and tie rods use a single set of tooling for a single specification, resulting in a non-interchangeable tooling spot welding method (i.e., the tooling is not interchangeable, and the wall panels need to be replaced for each set of structural components). Therefore, this structural form leads to a wide variety of tooling types, large storage space, and high manufacturing and maintenance costs. Utility Model Content

[0027] Example 1, when the structural component is the first telescopic arm assembly A (e.g.) Figure 1-3 (As shown).

[0028] The general-purpose spot welding fixture for the aerial work platform structure in this embodiment includes a front bracket, a rear bracket, a positioning bushing 5, a large bushing 9, a small bushing 10, a stop shaft 7 for blocking the end of the workpiece, a shaft hole positioning shaft 3, a positioning spacer 4 and a positioning rod 6 for positioning the structure, and a support shaft 8 for supporting the structure. The positioning spacer 4 is fitted outside the shaft hole positioning shaft 3, and the positioning spacer 4 and the positioning rod 6 are used to position the side of the structure.

[0029] In this embodiment, the front bracket and the rear bracket cooperate. The front bracket includes a front base and two front wall plates 1, which are arranged opposite to each other on the front base. The rear bracket includes a rear base and two rear wall plates 2, which are arranged opposite to each other on the rear base. The positioning bushing 5, the large bushing 9, and the small bushing 10 are all fitted onto the shaft hole positioning shaft 3.

[0030] The tooling features two sets of front wall panels 1 and rear wall panels 2, which are respectively fixed on the universal front base and rear base. The length of the two sets of wall panels can be adjusted to adjust the position of the universal base according to the needs of the first telescopic arm assembly A. The shaft hole positioning shaft 3 passes through the wall panel and the shaft hole of the first telescopic arm assembly A for positioning. The positioning rod 6 is fixed on the front wall panel 1 and rear wall panel 2 to position the side of the first telescopic arm assembly A. The support shaft 8 supports the bottom of the arm frame.

[0031] This spot welding fixture can be used in a separate, independent, joint positioning configuration based on the structure of the boom and tie rods. The joint distance can be adjusted according to structural requirements. With the width of the boom and tie rods not exceeding the spacing of each set of wall panels (two wall panels per set), this multi-structure universal design significantly increases the flexibility and versatility of the fixture positioning compared to the old, single-structure design. It also reduces the costs of fixture fabrication, maintenance, and design, as well as the frequency of wall panel replacement, thus improving work efficiency.

[0032] The wall panel assembly is divided into two groups, front and rear, and the distance between them can be adjusted according to the needs of the structural components. Both groups of wall panel assemblies are compatible with the above four specifications of structural components. The structural components are positioned using shaft hole positioning shaft 3, positioning spacer 4, positioning bushing 5, positioning rod 6, stop shaft 7, support shaft 8, large bushing 9, small bushing 10, etc., and the support shaft 8 supports the horizontal position of the parts. This tooling has precise positioning and good flexibility.

The universal spot welding fixture for the boom and tie rod can be used for multiple structures within the same vehicle model or for multiple vehicle models. The length direction of the boom and tie rod is basically unrestricted according to product characteristics and can be used for all vehicle models. The wall panels are detachable, and the universal spot welding fixture for the boom and tie rod can be used to replace the positioning wall panel specifications (detachable type) according to the product structural characteristics. The flexibility and versatility of the tooling are significantly enhanced; design, maintenance, and manufacturing costs are reduced; the frequency of tooling replacement is also reduced during use, improving work efficiency.
