Description

Technical Field

[0001] The invention relates to the field of spiral elastic element assembly, and in particular to an assembly device for a spiral elastic element. Background Art

[0002] Spiral elastic elements are widely used in aerospace, instrumentation, nuclear power and other fields. They are mostly used in single or double coils. Their function is to limit various parts on the shaft and fix the axial movement of parts. The high-standard application environment requires not only that such elements should have good performance stability, but also high appearance standards and structural dimensional accuracy. In actual production, in order to ensure the required appearance standards and structural dimensional accuracy, compaction and heat treatment are required. Before heat treatment, the spiral elastic element needs to be assembled in a standard outer cylinder tooling to ensure the shape of the spiral elastic element. Standardized assembly in the standard outer cylinder tooling is the key to the molding of the spiral elastic element.

[0003] At present, the processing methods or devices commonly used to assemble spiral elastic elements require operators to wear protective gloves and manually spin the spiral elastic elements to be processed one by one into the standard outer cylinder tooling, and then use tools such as wooden hammers for preliminary compaction to ensure that the spiral elastic elements are assembled in a standardized manner in the standard outer cylinder tooling. Then, the standard outer cylinder tooling with the installed spiral elastic elements is taken for the next step of heat treatment and compaction to further eliminate the defects in the structure or appearance of the element so that its size meets the requirements. The assembly process is cumbersome, requires many auxiliary tools, and has low installation efficiency. At the same time, the assembly process requires high job skills of operators. If you are not careful, defective products will appear, resulting in a low yield rate. In addition, manual operation is unstable, and improper operation may even cause the element to pop out and injure people. How to optimize the assembly of spiral elastic elements and improve the yield rate and installation efficiency of spiral elastic elements is a problem we have always wanted to solve. Summary of the invention

[0004] The purpose of the present invention is to provide a device for automatically assembling spiral elastic elements in view of the shortcomings of the prior art. The device can automatically assemble the spiral elastic elements in a standardized outer cylinder tooling, solve the problems of unstable manual operation and low yield rate, greatly improve the yield rate of the spiral elastic elements, and at the same time, improve the installation efficiency of the spiral elastic elements and facilitate operation.
