定义
A support block is a fundamental component in industrial positioning fixtures, designed to maintain consistent workpiece elevation and prevent deflection during machining, assembly, or inspection processes. These blocks are typically mounted to fixture bases and provide rigid, repeatable contact points that ensure dimensional accuracy across production batches.
工作原理
The support block operates on the principle of rigid body support, creating stable datum points that counteract gravitational and machining forces. By maintaining precise height dimensions and flat contact surfaces, it ensures workpieces remain in the correct spatial orientation relative to cutting tools or measurement devices throughout the operation cycle.
材料
Typically manufactured from hardened tool steel (A2D2or O1 grades)stainless steel (304 or 416)or aluminum alloy (6061-T6) with hardness ranging from 45-60 HRC for steel variants. Surface finishes of 0.8-1.6 μm Ra are standard for contact faces.
Flatness
0.005 mm
Mounting
M6 or M8 threaded holes
Parallelism
0.01 mm/m
Load Capacity
500-5000 N depending on material
Standard Sizes
10x10mm to 100x100mm cross-section
Height Tolerance
±0.005 mm
标准
ISO 9001DIN 6325ASME Y14.5

常见问题

What is the primary function of a support block in positioning fixtures?

The primary function is to provide stable, repeatable height reference points that prevent workpiece deflection and maintain dimensional accuracy during machining or assembly operations.

How do I select the appropriate material for a support block?

Material selection depends on application requirements: tool steel for high-wear applications, stainless steel for corrosion resistance, and aluminum for lightweight applications where frequent adjustment is needed.

Can support blocks be customized for specific applications?

Yes, support blocks are often custom-machined with specific heights, mounting patterns, surface features, or special materials to meet unique fixture requirements.
