Application of U-shaped square boxes With the continuous development of industry, L-shaped square boxes have been widely used in equipment manufacturing and welding processing industries, changing the clamping and positioning methods in traditional industry and promoting many newer process methods. of production. Through continuous efforts, U-shaped square box products have been highly recognized. Therefore, it can be well applied in certain situations. It is currently known that L-shaped square box products are widely used in steel structures, various vehicle body manufacturing, rail transit welding, bicycle and motorcycle manufacturing, engineering machinery, frames and boxes, Pressure vessels, robot welding, sheet metal processing, metal furniture, equipment assembly, industrial pipelines (flanges), detection systems, etc.
A U-shaped square box is a specialized fixture component, often used in modular workholding systems like welding tables or machining setups. It typically combines the stability of a square or rectangular block with a U-shaped channel or cutout feature. This design allows it to support, locate, or clamp round or square workpieces accurately, bridging the gap between standard V-blocks and flat positioning blocks. Its primary function is to provide stable, multi-point contact and precise positioning for various fabrication tasks.
Imagine a solid square or rectangular block, typically made of metal, with a precise U-shaped channel machined into one or more faces. This is the essence of a U-shaped square box. The square body provides a stable base and multiple mounting faces, often compatible with grid-based systems (like those found on welding tables), while the “U” channel offers specific advantages:
It acts as a versatile Positioning block fixture, enhancing the capabilities of standard workholding equipment.
1. Convenient connection of square boxes to easily form a frame structure;
2. Combined with different supports, it can form a similar platform foundation;
3. 5 working surfaces;
4. Wide range of specifications, up to 4000mm;
5. For vertical use, support angle iron can be used to increase strength.
When evaluating or selecting a U-shaped square box, consider these features:
Typically manufactured from high-quality steel (like tool steel or surface-hardened structural steel) for durability, wear resistance, and stability. Materials offering good machinability and resistance to deformation under load are preferred in Metal fabrication components.
Critical dimensions, such as the parallelism and perpendicularity of faces and the accuracy of the U-channel profile, are usually held to tight tolerances. This ensures reliable and repeatable positioning.
May feature threaded holes, counterbored holes, or compatibility with specific modular fixture systems (e.g., Ø16mm or Ø28mm holes for welding table bolts) allowing secure mounting to the primary work surface.
Often ground or finely machined for flatness and smoothness. Surface treatments like black oxide or nitriding might be applied to enhance corrosion resistance and durability, similar to high-end Welding table accessories.
Available in various sizes (length, width, height) and U-channel dimensions to accommodate different workpiece sizes and applications.
The unique geometry of the U-shaped square box makes it suitable for several tasks:
Incorporating these components into your workflow offers several advantages:
Selecting the appropriate U-shaped square box depends on the application:
| Factor | Key Consideration | Example Relevance |
|---|---|---|
| Size & Capacity | Match the box dimensions and U-channel size to the typical workpieces. | Small box for intricate parts, large box for structural elements. |
| Material & Hardness | Consider the required durability, load-bearing capacity, and potential for wear. | Hardened steel for high-wear applications vs. standard steel for general positioning. |
| Accuracy Tolerance | Select based on the precision requirements of the final product. | High precision for aerospace components vs. standard tolerance for general fabrication. |
| Mounting Compatibility | Ensure the box integrates with your existing table or fixture system (hole size, spacing). | Requires Ø16mm holes for System 16 welding tables. |
| Configuration | Does the U-channel need to be on a specific face? Are multiple channels needed? | Single channel for simple pipe support vs. multiple faces for complex jigs. |
U-shaped square boxes rarely work in isolation. They are most effective when used as part of a larger system of Fixture locating elements. They complement other standard components like:
In conclusion, the U-shaped square box, while perhaps not a universally standard term, represents a highly useful category of workholding component. Its blend of stability and specialized geometry makes it an invaluable tool for achieving precision and efficiency in welding, machining, and assembly applications, particularly within modular fixturing environments.

The L-shaped multifunctional square box is used for height positioning or platform expansion and positioning or clamping of other accessories. It is a component that positions the support on the platform to ensure that the workpiece reaches a certain height requirement during the processing.
It is the basic platform of flexible combined tooling, and its function is to support the workpiece being processed and positioning fixtures, clamping fixtures, calibration fixtures, etc.
The 0-225° angle gauge is used for height positioning or platform expansion and positioning or clamping of other accessories. It is a component that positions the support on the platform to ensure that the workpiece reaches a certain height requirement during the processing. The angle gauge is mainly used for positioning and supporting angled workpieces. The angle gauge can continuously adjust any angle between 0° and 180°. The reading is read from the side disc scale. When the required angle is adjusted, tighten the clamping screws on the side. There are system holes and slots on the two angle arms, and other positioning fixture modules can be connected in the holes and slots for positioning or clamping.
