FANTA
The FANTA universal chuck is a versatile clamping device that is often used to hold small workpieces. The following is a detailed description of the chuck:
Basic Overview
Definition: Parallel clamps, also known as machine-mounted tigers, are a universal fixture that is often used to hold small workpieces. They are commonly used as accessories for milling machines and drilling machines, and are fixed to the machine table to hold workpieces for cutting and machining.
Working Principle: By turning the spanner, the screw rod moves through the screw nut, which moves the movable jaw to clamp or release the workpiece. The size of the workpiece that can be held cannot exceed 160mm.
Main Types
By structure classification: including universal chuck, angle clamping chuck, tilting chuck for machine tools, high precision chuck for machine tools, and power chuck for machine tools.
By applicable machine classification: suitable for milling machines, drilling machines, grinding machines, and CNC machines.
Construction Features
Assembly Structure: The assembly structure of the flat-jaw pliers is a removable threaded connection and pin connection; the linear motion of the movable jaw is converted from a screw motion; the working surface is a friction surface between a helical pair, a guide pair, and a gap-fitting axis and hole.
Compact Design: The flat-jaw pliers have a compact design with a simple composition.
Use Method
Position correction: Before machining, especially when machining interrelated surfaces, the flat vise should be carefully adjusted in its longitudinal, transverse, and horizontal positions on the workbench.
Precautions: The surface to be machined on the workpiece must be higher than the jaw of the vise, otherwise it must be raised with a parallel iron. In order to securely clamp the workpiece and prevent it from slipping during planing, the relatively flat surface must be firmly pressed against the iron and the jaw of the vise.
Visual inspection: Refer to the general technical conditions for machine tool products.
Accuracy inspection: mainly includes the parallelism between the upper surface of the anvil guide and the base plane, the perpendicularity between the fixed jaw and the upper surface of the anvil guide, and other items.
Application fields
They are widely used in milling machines, drilling machines, etc. for various surface, groove, angle, etc. processing.
In conclusion, flat-jaw chucks, as a universal fixture, have extensive application value in the field of mechanical processing. Their design is compact and simple, with strong clamping force and easy operation. When using flat-jaw chucks, it is necessary to follow certain operating methods and precautions to ensure processing quality and safety.
