D28 3D Welding Platform With Diagonal Holes 1000×1500mm is a three - dimensional flexible welding fixture platform. Its core innovation lies in the design of diagonal holes. By combining the orthogonal hole system with the diagonal hole system, it significantly improves the flexibility and efficiency of multi - angle positioning of complex workpieces.
• Model Definition:
D28: A standard hole system with a hole diameter of 28mm, compatible with industrial - common fixtures.
3D Welding Platform: Supports X/Y/Z three - axis positioning. The hole system is evenly distributed on the tabletop and sides, enabling three - dimensional clamping.
Diagonal Holes: An additional diagonal hole system (such as an inclination angle of 45° or 60°) is added, breaking through the limitations of the traditional orthogonal hole system.
1000×1500mm: The tabletop size is 1 meter (width) × 1.5 meters (length), suitable for small - and medium - sized workpieces or local precision welding.

2.Detailed Explanation of Inclined Hole Design
• Layout Method:
The inclined holes and orthogonal holes are distributed alternately to form a composite hole system network (for example, an inclined hole row is inserted into the orthogonal holes every 100mm).
The common inclination angle is 45° (suitable for most inclined - surface workpieces), and special angles such as 30° and 60° can also be customized.
• Functional Advantages:
Multi - angle positioning: Without additional angle pads, the fixture can be installed directly through the inclined holes to achieve clamping in non - orthogonal directions.
Reducing interference: The inclined holes provide clearance space for cantilever - type fixtures or sensors to avoid collisions with the workpiece.
Quick change - over: The inclined holes and orthogonal holes share the positioning pins, are compatible with standard fixtures, and shorten the adjustment time.

Typical application scenarios
1. Welding of complex geometric workpieces
- Case: Multi - angle branch welding of automobile exhaust pipes - Fix the branch pipes directly through inclined holes, avoiding multiple adjustments of the fixture angle.
- Advantage: The clamping efficiency is increased by 50%, and the weld consistency is better.
2. Precision alignment and inspection
- Case: Assembly of aerospace sheet metal parts - Install a laser tracker through inclined holes to calibrate the surface profile at non - orthogonal angles.
- Advantage: Reduces measurement blind spots, and the detection accuracy reaches ±0.1mm.
3. Education and small - batch production
- Case: Welding training in vocational colleges - Students can quickly understand the principle of spatial positioning through inclined holes and complete the welding of multi - angle practice parts.
- Advantage: The teaching is intuitive, and the equipment reuse rate is high.
Frequently Asked Questions (FAQ)
Q1: Does the inclined hole affect the overall rigidity of the platform?
• Answer: The inclined holes are designed in a staggered layout, and the aperture ratio is less than 15%. The impact on rigidity is negligible (verified by FEA simulation, the increase in deformation is ≤ 0.01mm).
Q2: Can inclined holes be machined on the existing orthogonal hole platform?
• Answer: It is theoretically feasible, but the hole position distribution needs to be recalculated and precision machining is required, which is costly. It is recommended to directly purchase a special platform for inclined holes.
Q3: Does the inclined hole fixture need to be customized?
• Answer: Standard D28 fixtures (such as pressure plates and support columns) can be used directly, and only the special angle fine - tuning module needs to be selected.
Functional Features and Technical Advantages
1. Three - dimensional Flexible Expansion Ability
- Three - dimensional Clamping: The tabletop, sides, and end faces are evenly distributed with orthogonal and inclined hole systems, supporting multi - face synchronous fixation of workpieces (for example, when welding pipe fittings, the inclined holes on the side fix the support arms).
- Modular Splicing: It can be expanded to a larger size through standard interfaces (such as splicing into a 2000×3000mm platform).
2. High Precision and Stability
- Inclined Hole Machining Process: Drilling is carried out using a five - axis CNC machining center to ensure angle accuracy and the smoothness of the hole wall.
- Anti - deformation Design: The layout of internal welding stiffeners is optimized, and thermal stress relief treatment is carried out to ensure no deformation during long - term use.
3. Compatibility and Economy
- Universal Fixture Adaptation: The inclined holes are compatible with D28 standard locating pins and compression bolts, eliminating the need for custom - made special fixtures.
- Reducing Tooling Costs: The use of angle adjustment modules is reduced, and the comprehensive cost is 20% - 30% lower than traditional solutions.
