Multi-layer investment casting combination suspension fixture

Abstract

The invention discloses a multi-layer investment casting combination suspension fixture. The multi-layer investment casting combination suspension fixture comprises a first supporting mechanism and asecond supporting mechanism which are separately fixedly provided with a rotary fixing mechanism; the rotary fixing mechanism of each of the first and second supporting mechanisms is movably providedwith a first bearing mechanism and a second bearing mechanism at an equal angle; and each first bearing mechanism is inserted and fixed in the corresponding second bearing mechanism. According to themulti-layer investment casting combination suspension fixture, rotation of the bearing mechanisms of a casting is realized by driving the fixing mechanisms to rotate by motors, so that the casting canbe placed at will at a height which is manually reachable, and placement is convenient and rapid, and can be realized without assistance of external force; meanwhile, distances between the bearing mechanisms is expanded or contracted at any time through effects of threaded rods and limiting plates, so that an available bearing space can be changed; and not only is requirement of the bearing spacemet, but also reasonable utilization of the space can be realized, and no space is wasted.

Description

technical field [0001] The invention belongs to the field of investment casting, and relates to a multi-level investment casting combined suspension tool. Background technique [0002] In the production process of investment castings, it is usually produced in large quantities, and the types of castings produced are different. In the production workshop, in order to distinguish the castings, different castings are usually piled together. Due to the wetness of the ground, the castings are placed for a long time. Corrosion occurs, and the same pile of castings occupies space on the ground, so the castings are placed on the holding tool during the casting production process. Most of the existing casting holding tools are placed directly on the shelf to save space, but for high It is inconvenient to pick and place the castings at the upper and lower places, and at the same time, when more castings are produced, the storage space of the castings cannot be accurately fixed, and th...

In order to distinguish castings in the production workshop, different castings are usually piled together. Due to the wetness of the ground, the castings are placed for a long time. Corrosion occurs, and the same pile of castings occupies space on the ground, so the castings are placed on the holding tool during the casting production process. Most of the existing casting holding tools are placed directly on the shelf to save space, but for high It is inconvenient to take and place the castings at the upper and lower places, and at the same time, when producing more castings, the storage space of the castings cannot be fixed accurately, so that it is impossible to expand the storage space in time
