Best Clamp Types by Industry – Seikou Maker

A fixture is a process equipment used to fix a workpiece so that it remains in the correct position during processing. Here are some of the best fixture types by industry:

Mechanical processing industry

Vise: This is one of the most common fixtures, suitable for milling, drilling and other processing of various small parts. It can clamp the workpiece manually or hydraulically, and can provide good clamping force and positioning accuracy.
Chuck: Commonly used in lathe processing, it can be divided into three-jaw chuck and four-jaw chuck. The three-jaw chuck can automatically center and is suitable for clamping round workpieces; the four-jaw chuck can clamp workpieces of different shapes by adjusting the position of the jaws separately, and the clamping accuracy is higher.

Automobile manufacturing industry

Welding fixture: The car body is assembled by welding many parts. The welding fixture is used to ensure the relative position accuracy of each part, ensure the welding quality and the body size accuracy. It usually adopts a multi-station combination design, which can position and clamp multiple parts at the same time, and has the function of quick clamping and disassembly.
Inspection fixtures: used for dimensional inspection of automotive parts. By comparing the workpiece with the positioning and measuring datums of the inspection fixture, it can quickly determine whether the workpiece meets the design requirements. For example, the engine cylinder block inspection fixture can detect multiple parameters such as the bore diameter, flatness, and position of the cylinder block.

Aerospace industry

Vacuum fixtures: Since aerospace parts are mostly made of lightweight and high-strength materials, such as carbon fiber composite materials, these materials are prone to deformation during processing. Vacuum fixtures fix the workpiece by forming a vacuum adsorption force on the surface of the workpiece, and can evenly apply clamping force to avoid deformation of the workpiece. It is suitable for processing large-area, thin-walled parts, such as aircraft wing panels.
Combination fixtures: Aerospace products have a wide variety of parts with complex shapes, and many are produced in single pieces and small batches. Combination fixtures can form the required fixtures by quickly assembling and adjusting standard fixture components according to the processing requirements of different parts. They have the advantages of high flexibility and low cost, and can meet the changing needs of aerospace industry products.

Electronics manufacturing industry

SMT placement machine fixture: In surface mounting technology (SMT), it is used to fix the circuit board to ensure that the electronic components can be accurately mounted to the specified position on the circuit board. This type of fixture usually has a high-precision positioning structure, can adapt to circuit boards of different sizes and shapes, and has a quick clamping function to meet the high-speed and efficient production requirements of the SMT production line.
Wave soldering fixture: It is used to fix the circuit board on the wave soldering equipment so that the soldering surface of the circuit board can evenly contact the solder wave crest to achieve reliable welding between the electronic component pins and the circuit board pads. The wave soldering fixture needs to have good high temperature resistance and insulation performance, and at the same time, it must be able to effectively prevent the circuit board from deforming and shifting during the soldering process.
