Description
Technical Field
[0001] This utility model relates to the field of positioning tooling technology, and in particular to a tooling for welding the frame of a forklift without a tailstock. Background Technology
[0002] The frame of a forklift without a tailstock is a crucial component, supporting the counterweight and mast. Therefore, the welding dimensional accuracy of the frame is extremely important; minor issues can result in unsightly assembly dimensions, while major issues can compromise forklift safety. Currently, most mainstream forklift frames are tailstock-based, making the dimensional accuracy requirements for tailstock-less frames even higher. Consequently, the welding positioning fixtures become even more critical.
[0003] The existing welding fixture uses the front axle as the positioning center, which restricts lateral opening. Once the front axle is positioned, other structures of the frame cannot be adjusted, and it is not conducive to the fixture being applicable to multiple products. Therefore, such welding fixtures have some disadvantages: 1. They are only suitable for a single product, require a large number of fixtures, and are bulky; 2. There are many fixtures to be used, requiring storage space and occupying a large amount of usable factory space; 3. The positioning dimensions of the welded supports cannot be guaranteed after deformation due to long-term use. Utility Model Content
