Description
Technical Field
The utility model relates to a turning attachment specifically indicates a turning attachment of area location placed in the middle.
Background
The lathe all needs to pass through anchor clamps and fixes the work piece when processing the work piece, because the particularity of some work pieces, it is irregular, when ordinary two-jaw chuck carried out the work piece clamping, the work piece can produce the position and remove, leads to the finished product that the processing was come out can't reach the drawing requirement, when the product after the processing did not have and can't reach the drawing requirement, need carry out a lot of reworking or process again after repairing, consequently reduced work efficiency, serious lead to that a batch of work piece is whole to be scrapped. To this end, a lathe fixture with a centering is proposed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problems and providing a lathe fixture with centering function.
In order to achieve the purpose, the utility model provides a lathe fixture with a middle positioning function, which comprises a chuck and a clamping jaw; the clamping jaws are mounted on the chuck through bolts; the chuck is characterized in that the chuck is also provided with a positioning seat and a positioning sleeve through bolts; the positioning seat is provided with a tensioning rod through a nut, one end of the tensioning rod is positioned in the positioning sleeve, the tensioning rod is provided with a limiting step, and the tensioning rod is provided with a centering positioning block.
Further preferably, the centering positioning block is slidably mounted between the tension rod and the positioning sleeve through a limiting step.
Further preferably, a spring guide groove is formed in the centering positioning block, and a spring is installed between the spring guide groove and the tensioning rod.
Further preferably, the positioning sleeve is provided with a fixed step, and the clamping jaw is provided with a positioning step matched with the fixed step.
The utility model discloses a design of anchor clamps has realized the front and back location of work piece, has fixed a position two relieved locations placed in the middle, simultaneously through the design of straining rod and spring, can the automatically regulated work piece hair bank error on the size, and work piece size, the shape that processing was come out all accord with the drawing requirement, have improved production efficiency simultaneously.
