Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tooling and fixture design technology, and in particular relates to a flange product positioning tooling. Background Technology
[0002] Traditional clamping fixtures have significant limitations in the machining of flanges with equal diameters at both ends. Integral fixtures, due to their fixed-size design, can only accommodate products of a single length. When machining flanges of different lengths, the entire fixture must be replaced, leading to frequent production line downtime and severely restricting processing efficiency. To improve adaptability, modular fixtures achieve specification switching by replacing some components. However, the component disassembly and assembly process is cumbersome, involving multiple locating pins, fasteners, and calibration steps, which is time-consuming and significantly increases non-machining time and the operator's workload.
[0003] More importantly, both integral and modular tooling require frequent changes or adjustments when dealing with products of various specifications. This necessitates multiple clamping and positioning operations, easily introducing accumulated errors in datum positioning. For flanges requiring multi-stage processing, secondary clamping deviations directly impact critical machining accuracy (such as product coaxiality and end face runout), making it difficult to guarantee stable accuracy and increasing production costs.
[0004] While existing technologies have attempted improvements, with some technicians employing adjustable pressure plates or modular components, manual intervention is still required for position adjustments or component selection. This process is complex and inefficient, making it impossible to achieve rapid and continuous switching between flanges of different lengths while maintaining accuracy. Therefore, there is an urgent need to develop a tooling system with length adaptive capabilities to fundamentally eliminate tooling changes, shorten adjustment time, reduce labor intensity, and ensure the stability of machining accuracy.
