Abstract
Description
Technical Field
[0001] This utility model relates to fixing fixtures, and more particularly to high-strength fixtures specifically for precision casting shell making. Background Technology
[0002] Casting shell making is the process of manufacturing the outer shell of a casting mold. Through specific processes, materials such as coatings and molding sand are applied or filled around the mold. After drying and hardening, a shell that can withstand the pressure and heat of pouring molten metal is formed. Then, the mold material inside the shell is melted away, and finally a hollow mold is obtained. Molten metal is then poured into it, and after cooling and solidification, the casting is obtained.
[0003] In the casting process, the casting shell workpiece needs to be gripped by a robot for other processes. Existing technology generally uses a single-point fixing method to grip and lift the workpiece. However, due to the large mass of the workpiece, the single-point fixing method cannot provide sufficient strength, and the single-point fixing is prone to workpiece shaking and breakage, making it impossible to carry out safe and stable rotation and tumbling shell making operations. Therefore, there is an urgent need to design a high-strength tooling that can be stably stressed after the workpiece is hung. Utility Model Content
[0004] Based on the shortcomings of poor stability and low strength of the existing single-point fixed hoisting structure, this utility model provides a high-strength tooling specifically for precision casting shell making.

[0010] Preferably, the load-bearing column is equipped with several crossbars for auxiliary fixation during gripping.
[0011] Preferably, the bracket is provided with several strip holes, and the fasteners are set at the strip holes and their positions are adjusted by sliding along the strip holes to align with the fixed positions on the workpiece.
[0012] As a preferred embodiment, the bracket is a ring-shaped frame plate, and the reinforcing structure consists of several reinforcing ribs. One end of the reinforcing ribs is connected to the load-bearing column, and the other end of the reinforcing ribs is connected to the ring-shaped frame plate.
