Description

Technical Field

[0001] This utility model belongs to the field of precision casting technology, specifically relating to a rapid assembly device for a complex turbine blade wax mold module. Background Technology

[0002] In precision casting, wax pattern modules play a crucial role. Wax pattern modules typically refer to wax parts or components used to create models of the final product. These modules can be used individually or combined to form more complex structures to meet the design requirements of different products. In precision casting, wax pattern modules are a key component of the lost-wax casting process. This method first involves injecting molten wax into a mold to create a wax model. Then, the wax model is coated with multiple layers of refractory material to form a shell. After the shell hardens, the wax model is melted and flows out through high-temperature heating, leaving a cavity. Finally, molten metal is poured into the cavity to cool and solidify, resulting in the desired casting. The combination of wax pattern modules allows for the precise replication of complex shapes and internal structures; therefore, the size and shape of the wax model must be extremely accurate, otherwise, the quality of the final casting will be affected.

[0003] In the process of assembling turbine blade wax mold modules, multiple welding and bonding operations are required. Due to the complex structure of turbine blade wax mold modules, the large number and size of blades, and the weight of the modules, the assembly of the modules is a great test of the operator's technical skills and operational proficiency. Moreover, the operator's physical strength is greatly consumed during long-term assembly, resulting in high work intensity. In addition, manual assembly has problems such as insufficient precision of the modules. Therefore, there is an urgent need to develop a rapid assembly device for complex turbine blade wax mold modules.

[0004] Chinese patent application CN119259913A discloses a wax model assembly device and method. The assembly device includes a frame, a lifting mechanism, a rotating mechanism, and a cleaning mechanism. The lifting and rotating mechanisms work together to enable precise lifting and 360-degree rotation of the wax model, eliminating the need for manual flipping. While this technology allows for automatic flipping of the wax model, for complex turbine blade wax model modules, there is a lack of a dedicated clamping mechanism between the wax model module and the robotic arm. Without this clamping mechanism, the wax model module can easily detach during the flipping process. Utility Model Content

[0048] First, rotate the screw at the top of the injection tube in the wax mold module into the three clamps for rough positioning. Then, rotate the locking cover. At this time, the three clamps move outward to clamp the screw. During the clamping and locking process, you will hear a clicking sound until it stops rotating, indicating that the screw has been clamped.

[0049] Then, adjust the height of the second lifting mechanism so that the base of the wax model module contacts the tray, and the center of the base coincides with the center of the tray. Align the turbine blade wax model with the scale line on the tray to measure the angle between the blades, thus ensuring that the distance can be evenly distributed during assembly. Driven by the motor, adjust the height of the first and second lifting mechanisms, and at the same time adjust the angle of the rotating connecting shaft (rotating 360 degrees with the central axis of the first lifting mechanism as the center) and the rotating mechanism (rotating 360 degrees with the central axis of the rotating connecting shaft as the center) to assemble and weld the 20 turbine blade wax models.

[0050] Finally, after the assembly is complete, push the unlock cover in the opposite direction, and then rotate the locking cover in the opposite direction. At this time, the three grippers move inward, rotating the screw out in the opposite direction.

[0051] The rapid assembly device for complex turbine blade wax mold modules in this embodiment can measure the angle between wax mold blades during assembly and evenly distribute the distance between wax mold blades. This device is a semi-automatic tooling driven by a motor, which greatly reduces the labor intensity of the operator, while improving the assembly efficiency and accuracy of wax mold modules, ensuring product quality, and ensuring the consistency and interchangeability of each wax mold.
