Description
Technical Field
The utility model relates to the technical field of machining, in particular to a multifunctional V-shaped positioning block for precision machining.
Background
The V-shaped block is frequently used in machining places, is suitable for correction, scribing, positioning and other purposes of precision shaft parts, and can also be used for detecting the perpendicularity and parallelism of workpieces.
The V-shaped positioning block is one of the positioning elements commonly used in lathe fixtures, in order to ensure the machining precision during machining, the workpiece is firstly installed on the lathe and occupies a correct position, namely the workpiece is positioned, after the workpiece is positioned, in order to keep the workpiece in the position all the time during machining, the workpiece is pressed and clamped firmly, which is called clamping of the workpiece, and the whole process from positioning to clamping is called installing of the workpiece.
The angle of a single V-shaped block cannot be adjusted, so that in order to adapt to workpieces with different diameters and sizes, the only method is to only equip the V-shaped blocks with different specifications, a great deal of funds are needed, and a certain space is additionally occupied when the redundant V-shaped blocks are not used.
