Description

Technical Field

[0001] The utility model relates to the technical field of wax mold tree welding, in particular to a tree assembling position-changing mechanism for controlling the posture change of an assembled tree. Background Art

[0002] A wax mold tree is formed by welding multiple wax molds on a wax rod to form a tree-shaped structure, that is, a wax mold tree (assembled wax mold tree). Wax mold trees are often used in the field of investment casting and are used in military, aerospace, and many civilian high-precision and sophisticated equipment. The welding process of the wax mold tree directly determines the quality of the investment casting product. If the casting is not good, air bubbles will be formed at the welding position, resulting in the scrapping of the investment casting product.

[0003] Existing wax mold tree welding equipment usually uses manual operation for welding. Due to the manual flexibility of people, the welding work of the wax mold tree can be achieved from different angles through skills. However, manual operation inevitably brings the problem of poor product consistency, and in the molten state of the solder used during the welding process, gaseous substances will be volatilized, which is harmful to the health of the operators.

[0004] If manual operation welding is not used, a manipulator is required to weld the wax mold on the wax rod. The operation flexibility of the manipulator is limited, and the wax rod needs to be assisted to move for cooperation. The existing wax mold tree welding device cannot move the wax rod to cooperate with the movement of the manipulator. Summary of the Utility Model
