Description

Technical Field

[0001] This utility model belongs to the technical field of clamping equipment, and relates to a clamping platform with angle flipping function. Background Technology

[0002] When using vertical drilling machines and radial drilling machines to process and position irregularly shaped parts and components with spatial position and angular relationships during assembly, the spindles of these machines cannot be tilted at various spatial angles. Without the use of CNC machining centers or dedicated assembly fixtures to process the spatial position and angular features of the parts, it is impossible to guarantee the spatial dimensional requirements of the parts and components. Due to the variable product structure types and the numerous processing features and spatial angular positions, current methods primarily rely on a large number of dedicated assembly fixtures for positioning and spatial position and angular alignment of parts and components before processing. This results in high costs for specialized process equipment manufacturing, long production cycles, and the inability to achieve mass production. Alternatively, CNC machining centers can be used for clamping and machining of spatial angular positions, but the accuracy of secondary clamping and positioning is not high, making it difficult to guarantee the dimensional requirements of products with high precision. This research presents a clamping platform device with an angle flipping function, which can quickly realize the processing and assembly positioning of various irregularly shaped parts and components with spatial position and angular relationship structural features. This reduces the number and types of special process equipment for assembly positioning and the scrapping of parts caused by secondary positioning errors. It can improve assembly efficiency and product quality while achieving a breakthrough in new methods for processing and clamping irregularly shaped features and non-planar normal features.

[0003] In summary, existing technologies have the problem that traditional vertical drilling machines and radial drilling machines rely on a large number of special fixtures and CNC machining centers because the spindle of the machine cannot be tilted at a spatial angle. Utility Model Content

It solves the process and operation bottlenecks in processing and clamping and positioning irregularly shaped features and non-planar normal features. It is a simple, efficient and reliable auxiliary positioning device.
