Three dimensional flexible tooling platform

The 3D flexible tooling platform is designed based on the principle of welding fixtures in mechanical processing. Through the platform foundation and groove hole attachments, the attachments are connected and matched to form a set of welding combination fixtures.

Composition of 3D flexible tooling platform:

1. Workbench

The five working surfaces of the workbench have holes with grid markings of 100x100 mm (D28 series) or 50x50mm (D16 series). The precision of its five plane, parallel, and vertical tolerances, as well as the positional accuracy of holes, are all very high. The positioning on the table and the combination between the table and other modules have sufficient precision requirements for use. The size of the basic countertop can be freely selected from 1000x1000mm to 4000x2000mm, and the size can be customized.

2. Modules

The standard modules include positioning and clamping right angle blocks, L-shaped positioning blocks, U-shaped positioning blocks, universal stop blocks, universal clamping and positioning angle molds (adjustable from 0-225 degrees), V-shaped blocks, and V-shaped angle molds. All modules have standard holes (Φ 28 or Φ 16) at intervals of 50 or 25mm, which can achieve workpiece positioning and clamping.

3. Locking pin

This is the basic component for implementing a hole system clamping system, used for positioning and clamping. There are five steel balls at the front end of the bolt. After inserting into the positioning hole, manually rotate the bolt clockwise (or pull the handle), and the five steel balls will pop out and lock onto the inclined surface of the hole, completing the positioning and clamping; When releasing, rotate the pin in the opposite direction to pull it out. The locking force of each bolt can reach 5 tons, and the shear force is 25 tons. There are various specifications for the shape and length of the bolt to choose from.

4. Clamping device

Clamping devices are available in flat, vertical, and 45 degree clamping directions; According to the operation method, there are bolt clamping, clamping, and handle screw clamping; There are also manual, pneumatic or hydraulic options available. Among them, screw clamps with compensation are commonly used. This type of clamp adds elastic expansion and contraction in the cantilever, offsetting the lateral force during clamping to compensate for the deformation of the fixture itself and the gap during insertion. The clamping force is perpendicular to the force surface.

The clamping head is made of carbon steel, stainless steel, and nylon materials to meet different workpiece requirements. If equipped with two-point or three-point clamping bridges, workpieces at two different heights can be clamped simultaneously. Alternatively, the clamping head can be machined according to the clamping surface.
