Carriage Body/Plate

The carriage body/plate is a foundational structural component used in moving carriage or platform systems within industrial equipment. It provides a rigid framework that supports and integrates other components such as guides, bearings, drive mechanisms, and tooling attachments. This part ensures dimensional stability, load-bearing capacity, and precise alignment during linear or rotational motion. Typically manufactured from carbon steel, aluminum alloy, or cast iron, the carriage body/plate is available in a range of sizes and configurations to suit various applications. Key parameters include overall width (100–600 mm), overall length (200–1200 mm), and plate thickness (10–40 mm). Material grades may range from Q235 to Q345 per GB/T 700, and surface hardness can be specified between HRC 40 and 55. Flatness and parallelism tolerances are critical for precision motion, typically within 0.02–0.10 mm and 0.03–0.15 mm respectively, per ISO 1101. The maximum load capacity ranges from 500 to 5000 kg, and the operating temperature range is -20 to 80 °C. Surface treatments such as black oxide or phosphating may be applied for corrosion resistance and friction control. The weight of the component varies from 5 to 50 kg, affecting inertia and motor sizing. These values are reference ranges and must be verified for the specific model and application. The carriage body/plate is designed to mount onto linear guides or rails and connect to drive systems such as ballscrews, belts, or actuators. Its flat surfaces and mounting features allow precise installation of other components while resisting deformation under operational loads. When selecting a carriage body/plate, engineers must consider the required load capacity, travel length, mounting interface, and environmental conditions. Verification of dimensional tolerances, material properties, and surface treatments is essential to ensure compatibility and performance. Maintenance signals include visible wear, deformation, or loosening of mounting bolts, which may indicate overloading or misalignment. Failure boundaries are defined by the maximum load capacity and operating temperature range; exceeding these limits can lead to permanent deformation or fracture. Always consult the legal manufacturer or supplier to confirm model-specific values and standards.

The carriage body/plate functions as a stationary or moving structural element that transfers forces and maintains geometric integrity. It typically mounts to linear guides or rails and connects to drive systems such as ballscrews, belts, or actuators. Its flat surfaces and mounting features allow precise installation of other components while resisting deformation under operational loads. The plate distributes loads across its area, ensuring stability and alignment during motion. Material selection and thickness influence rigidity and load capacity. Proper installation and alignment are critical to prevent premature wear or failure.
