From “replacing manual labor” to “surpassing manual operation,” automatic straightening technology has greatly improved the production efficiency and product qualification rate of shaft and rod components. Nevertheless, certain automated equipment still contains error-prone factors that compromise straightening results, posing a major challenge to intelligent straightening.
This series of articles will focus on the pain points in the machining of shaft and rod components and conduct an in-depth analysis of how SINOTEST addresses this challenge with innovative solutions, advancing automated straightening into a new stage featuring intelligence and zero manual intervention.
Take conventional automatic straightening machines as an example: the workpiece support mechanism of most equipment still requires manual positioning. This process not only slows down production cycle time, but also introduces positioning errors resulting from human operation, which directly impairs the stability and consistency of straightening—this constitutes the core bottleneck of the aforementioned problem.
How to eliminate this core bottleneck?
SINOTEST delivers a straightforward and powerful solution through its fully tooling self-adjusting straightening machine: building upon the conventional main frame, loading mechanism, workpiece clamping mechanism, and measuring mechanism of traditional equipment, this machine innovatively integrates a support guiding mechanism and a support driving mechanism.
The complete system adopts servo motors for full closed-loop control, enabling precise adjustment of the three-dimensional coordinates of the support mechanism and delivering ultra-high repetitive positioning accuracy.
The working principles of these two core mechanisms are as follows:
- Driven by servo motors and gears, the support driving mechanism moves the support unit precisely along the guiding mechanism to realize adaptive adjustment of the workpiece supporting position.
•Adopting guide rails and rack-and-pinion transmission pairs, the support guiding mechanism effectively eliminates axial play of the support structure while guaranteeing axial positioning accuracy.
Straightening machines equipped with the above mechanisms eliminate the need for manual repeated shifting of support points during product changeovers, and no manual intervention is required throughout the straightening process.
The benefits are immediate: the positioning accuracy of tooling adjustment has improved dramatically from 2 mm to 0.1 mm, and human-induced errors are systematically eliminated. Meanwhile, the single-cycle adjustment time has been reduced from 15 minutes to 3 minutes, delivering a qualitative leap in equipment stability, product qualification rate, and production efficiency.
Furthermore, the workpiece clamping mechanism of this product is fully compatible with self-adjusting tooling to ensure an efficient and precise straightening process. Integrating driving and data acquisition functions, the clamping mechanism accurately collects rotation angles and performs dimensional measurements at multiple positions in coordination with the self-adjusting tooling to precisely reproduce the three-dimensional features of workpieces.
Such measurement data can not only be utilized for real-time optimization of straightening strategies but also for troubleshooting abnormal straightening procedures, adding an extra layer of guarantee for efficient and high-precision straightening.
The breakthrough of SINOTEST’s fully tooling self-adjusting straightening machine eliminates uncertainties caused by manual intervention completely, addresses the challenges of high efficiency and intelligent straightening for automatic straightening equipment, and sets a new benchmark for high-efficiency and high-consistency machining of shaft and rod components.
