The powertrain tightening environment is complex, placing high demands on the comprehensive performance of tightening equipment. Relying on its mature product system and extensive on-site experience, Danikor has launched a complete set of intelligent tightening solutions.

I. Industry Pain Points

1. Complex Working Conditions and Wide Torque Span
The powertrain tightening site involves various interlaced working conditions, including flat stations, single-side interference, multi-side interference, counterbores, and deep holes, with varying levels of difficulty. Conventional equipment is often unable to flexibly adapt. At the same time, the tightening torque for different bolts varies significantly. Standard tightening equipment has a single specification and a limited torque coverage range, making it unable to meet diverse fastening operation requirements.

2. Positioning Accuracy Deviation Issues; Assembly Efficiency and Cost of External Hexagon Screws are Unsatisfactory
Some assembly stations have fixture positioning deviations and product manufacturing accuracy errors, which can easily lead to inaccurate bolt alignment, directly affecting the overall assembly quality and finished product yield rate. The assembly of external hexagon screws commonly uses traditional 2D camera positioning, which not only involves high equipment procurement costs but also slows down the overall production cycle. Additionally, its correction capability is limited, and the assembly results are not ideal.

3. Low Production Efficiency in Dense Stations
In stations like the engine cylinder block, where the number of bolts is high and they are arranged very densely, the working space is extremely compact. Using conventional single-set tightening equipment for operations makes it difficult to match the production efficiency required for large-scale mass production.

4. Disconnected Process Flow
Processes such as screw feeding, transfer, and tightening are independent of each other, and the equipment cannot operate in a coordinated manner, making it difficult to achieve fully automated process flow, thereby limiting the intelligence level of the entire production line.

II. Corresponding Solutions

1. Full Category Modules Paired with Graded Operation Mode, Adapting to Various Conditions and Full Torque Range
Danikor's tightening product matrix covers universal modules, servo modules, integrated handheld modules, handheld vacuum pick-up modules, mechanical quick-change modules, and non-standard customized modules. For extra-large bolts and special working conditions, non-standard customization services are available, fully adapting to tightening requirements with a wide torque span. The equipment is matched with multiple screw bit heads, such as standard, swing-arm, and swing-nozzle types, which can be flexibly selected based on bolt specifications, length-to-diameter ratio, and on-site space. Before project implementation, a professional grading assessment of the on-site conditions is conducted, and the operational difficulty is classified according to the degree of interference: For simple conditions such as flat, non-interference areas or areas with slightly limited space, and single-side interference scenarios, the blow-feeding tightening mode is used to improve efficiency. For high-difficulty conditions such as multi-side interference, deep holes, counterbores, and large-area fixture obstruction, the vacuum pick-up tightening solution is adopted, and the equipment stroke is precisely set according to the on-site clearance height, ensuring the tightening mechanism successfully reaches the operation point.

2. Innovative Floating Tightening Structure, Balancing Correction, Cost Reduction, and Speed Increase
To address fixture positioning deviations, product manufacturing accuracy errors, and the difficulties in assembling external hexagon screws, Danikor's floating tightening solution replaces the traditional 2D camera positioning mode. This structure can adapt to positional deviations within the range of 0.5-2.5mm, effectively compensating for various errors in the assembly process, significantly improving the bolt insertion success rate and tightening pass rate, while reducing equipment investment costs, speeding up the production cycle, and providing better correction results. If the actual on-site deviation exceeds the equipment's adaptive range, a professional technical team will conduct a special assessment based on the site conditions and tailor an optimization solution.

3. Multi-Spindle Synchronous Operation, Increasing Capacity in Dense Stations
For stations with a high number of densely arranged bolts and extremely compact space, such as engine cylinder blocks, a multi-spindle synchronous tightening solution is adopted. Multiple sets of tightening mechanisms operate in coordination, significantly improving the overall production efficiency of the station under the premise of strictly ensuring tightening quality, thus adapting to the enterprise's large-scale mass production rhythm.

4. Seamless Equipment Linkage, Creating a Fully Automated Process System
Danikor's intelligent tightening system can achieve seamless linkage with the front-end automatic screw feeding equipment, connecting various production stages, and realizing fully automated processes from screw feeding, transfer, to tightening. This builds an integrated intelligent assembly system, comprehensively enhancing the automation and intelligence level of the production line.

Conclusion
Danikor's intelligent tightening system, with its comprehensive product matrix, refined capability to adapt to working conditions, and stable, reliable tightening accuracy, overcomes various fastening challenges in complex powertrain working conditions.
