The working principle of the Ang-fixed vise primarily relies on its design features and structural functions. This type of vise, known in English as a "compound ang-fixed vise," is a machine tool accessory assembled on milling machines for clamping workpieces. Its working principle can be summarized as follows:
1. Bidirectional Clamping Function The double-headed Ang-fixed vise possesses a moving and clamping function. Both jaws advance simultaneously to achieve workpiece clamping. This design enables the workpiece to be automatically self-centered during the clamping process and ensures repeatable positioning from both sides, guaranteeing accurate fixation of the workpiece.
2. Prevention of Workpiece Lifting Both movable heads are designed with an angle-fixed downward locking mechanical mechanism. This mechanism can effectively prevent the workpiece from lifting during the clamping process, maintaining its stability.
3. Use of Fixed Plate By locking the rear fixed plate, the operational mode of the vise can be altered, converting it into a large-opening vise to adapt to the clamping requirements of different workpieces.
Furthermore, the design of the Ang-fixed vise takes operational convenience and safety into account. For instance, the main vise body is mounted on a swivel base and can rotate around the axis line of the base. When rotated to the required direction, the clamping screw is tightened by moving the clamping handle, which then secures the main vise body under the action of the clamping disc. This design not only facilitates workpiece positioning and clamping but also improves working efficiency.
In summary, through its unique bidirectional clamping function, mechanism to prevent workpiece lifting, and flexible fixed plate design, the Ang-fixed vise achieves stable and accurate clamping of workpieces, making it an indispensable and vital tool in mechanical machining.
