Assembly Tooling Fixtures

Performance advantages of Xincheng Assembly Tooling Fixtures

1.Precision positioning system: "Reference guarantee" with millimeter-level accuracy

The positioning components are made of high-hardness alloy materials (such as 40Cr quenched and tempered, with surface quenching hardness reaching HRC50-55), and are precisely ground. The dimensional tolerances of the positioning pins and positioning blocks are controlled within ±0.01mm. Equipped with a multi-directional adjustable positioning structure, it supports fine-tuning sections for the X/Y/Z axes and rotation directions, which can precisely match the minute dimensional deviations of different batches of components. For complex workpieces such as curved surfaces and inclined surfaces, a profiling positioning design is adopted to ensure that the positioning surface is 100% in contact with the workpiece surface, effectively avoiding displacement deviations during the assembly process. The assembly accuracy is stably controlled within the range of 0.02-0.05mm, which is far superior to the assembly accuracy of manual assembly.

2. Smart Clamping Device: The "Balance Technique" of Safety and Flexibility

It adopts multi-power clamping modes such as pneumatic, hydraulic or electric. The clamping force can be adjusted according to the material characteristics of the workpiece (range 50-5000N). It is equipped with a pressure sensor to provide real-time feedback on the clamping status. When the force value exceeds the safe range, it will automatically stop and alarm to prevent workpiece damage. The clamping mechanism adopts a fast-response design, with the clamping/releasing action taking no more than 0.3 seconds. Combined with the interlocking control logic, it can achieve synchronous clamping at multiple stations, significantly reducing the auxiliary operation time. For vulnerable or thin-walled parts, flexible clamping pads (such as polyurethane or nylon materials) are provided to ensure the reliability of clamping while preventing surface scratches or deformation of the workpiece.

3. Modular structure: "Production flexibility" for rapid adaptation

The main frame is made of aluminum profiles or carbon steel welded structure, and undergoes aging treatment to eliminate stress, ensuring no deformation during long-term use. The core functional components (positioning blocks, clamping cylinders, guide sleeves) adopt standardized interface design, supporting quick disassembly and replacement. It can complete the tooling switch for different products within 30 minutes, meeting the production requirements of small batches and multiple varieties. Meanwhile, the framework reserves expansion interfaces, which can add functional modules such as detection sensors and automatic feeding mechanisms according to the upgrade requirements of the production process, achieving seamless connection between "tooling and production line".

4. Humanization and Safety: A "Safety net" to Lower the Threshold for Operations

The layout of the tooling follows the principle of "ergonomics", with the operation height controlled within the range of 750-900mm. The clamping operation adopts foot switches or touch buttons, reducing repetitive actions such as bending over and raising hands, and lowering the labor intensity of workers. Equipped with dual safety protection: On the mechanical level, an anti-misoperation interlock device is adopted. When the workpiece is not positioned in place, the clamping mechanism cannot be started. At the electrical level, emergency stop buttons and sound and light alarm devices are adopted to ensure a rapid response in case of abnormal situations. The surface of the tooling is treated with electrostatic powder coating, which is oil-proof and rust-proof. Moreover, the corners and edges are designed with arc transitions to avoid the risk of bumps and scratches during operation.

5. Durability and Ease of Maintenance: "Long-term Effectiveness" for Reducing usage costs

The key moving parts (such as guide shafts and cylinder pistons) adopt imported seals and lubricating grease, which are wear-resistant and aging-resistant. Under normal usage conditions, the service life of the core components can reach over one million times. The tooling is equipped with centralized lubrication interfaces and oil level observation Windows. Regular maintenance only requires the replenishment of grease, without the need for complex disassembly. The vulnerable parts (such as locating pins and clamping pads) are all standardized accessories, which are convenient to purchase and replace, significantly reducing maintenance costs and downtime.
