Chassis Fixture: Weight Capacity Up to 1500 kg

Component Specifications

Definition

A specialized industrial fixture designed to accurately position and rigidly clamp automotive chassis components during assembly processes. It ensures dimensional stability, repeatability, and alignment for welding, fastening, or inspection operations at chassis assembly stations. The fixture typically incorporates adjustable clamps, locators, and supports to accommodate variations in chassis models while maintaining tight tolerances.

Working Principle

The chassis fixture operates on mechanical clamping principles using pneumatic, hydraulic, or manual actuators to apply controlled force. It employs precision locators (pins, blocks) to reference datums on the chassis, ensuring correct positioning. Clamping elements secure the chassis against these locators, preventing movement during assembly. Some advanced fixtures incorporate sensors to verify part presence and clamping force.

Materials

Primary structure: Steel (AISI 4140 or equivalent, hardened to 45-50 HRC). Locators and wear surfaces: Tool steel (D2 or A2, hardened to 58-62 HRC). Clamping arms: Alloy steel. Bushings: Bronze or hardened steel. Fasteners: Grade 8.8 or higher steel.

Frequently Asked Questions

What is the primary function of a chassis fixture?

To securely hold and precisely position vehicle chassis components during assembly operations like welding, bolting, or inspection, ensuring dimensional accuracy and repeatability.

How often should chassis fixtures be calibrated?

Calibration should be performed every 6-12 months or after 10,000 cycles, depending on usage intensity and tolerance requirements. Regular daily checks for wear and damage are also recommended.
