Dalian 20-Axis Camshaft Cover Tightening Machine: Core Technology Analysis of Multi-Axis Collaborative Tightening

In the field of automotive engine assembly, the tightening accuracy of the camshaft cover directly impacts the engine's sealing performance and operational stability. The 20-axis camshaft cover tightening machine, leveraging multi-axis collaborative technology, serves as the core equipment for high-efficiency mass production assembly. It addresses industry pain points such as low efficiency and uneven force distribution in single-axis tightening, meeting the demands of large-scale, high-precision assembly.

The core of multi-axis coordinated tightening lies in "synchronous control + precise allocation," which is also the key distinction between a 20-axis machine and conventional tightening equipment. Equipped with a high-precision servo control system, the device enables synchronized startup and tightening of all 20 axes, avoiding force deviation on the camshaft cover caused by sequential single-axis operation. This prevents issues such as sealing gaps and bolt loosening while boosting assembly efficiency by 6-8 times, aligning with the mass production pace of engines.

Dalian's 20-Axis Camshaft Cover Tightening Machine employs dual-loop control technology for torque and angle, ensuring precision. Each tightening axis is equipped with a torque sensor and angle encoder, providing real-time feedback on operational data. The PLC system dynamically adjusts torque distribution across all axes, ensuring uniform force application on the 20 bolts with a torque deviation controlled within ±3%, fully meeting the stringent assembly standards of the automotive industry. The equipment can flexibly preset tightening programs for different machine models, supporting segmented tightening and torque compensation, and is compatible with multi-specification camshaft cover assembly.

The error-proofing and traceability system further enhances operational reliability. The equipment integrates a visual positioning module to accurately identify the camshaft cover installation station, preventing misassembly or omissions. It also automatically records torque, angle, and time data for each tightening operation, supporting full-process traceability for easier quality inspection later. Additionally, the equipment features modular design, allowing the 20 tightening axes to be independently adjusted and maintained, reducing downtime costs and ensuring continuous production line operation.

Compared to traditional multi-axis equipment, the collaborative control technology of Dalian's 20-axis camshaft cover tightening machine offers greater adaptability. It can meet the assembly requirements of conventional fuel engines while also being upgraded through programming to suit similar workstations like motor end covers for new energy vehicles. This technology serves as a crucial piece of equipment for intelligent upgrading in automotive manufacturing, providing reliable technical support for high-precision and high-efficiency assembly.
