Abstract

The invention discloses a positioning device of a workpiece. The positioning device of the workpiece comprises a carrier table with a horizontal end surface. A reference block and an auxiliary positioning block are fixed to the carrier table. The reference block is provided with a reference surface perpendicular to the horizontal end surface of the carrier table. The auxiliary positioning block is arranged in the position right facing the reference surface and provided with at least two through holes perpendicular to the reference surface. Each through hole is internally provided with an elastic element and at least one rigid round ball in clearance fit with the through hole. The end, right facing the reference surface, of each through hole is open, and the other end of each through hole is closed. One end of each elastic element abuts against the closed end of the corresponding through hole, and the other end of each elastic element pushes the corresponding round ball along the corresponding through hole. A block portion is arranged at the open end of each through hole. Through the auxiliary positioning mode that the elastic elements are arranged in the multiple sets of through holes to push the rigid round balls, the maintenance cost is reduced, and the positioning accuracy is higher.

Description

technical field [0001] The invention relates to a workpiece positioning device. Background technique [0002] With the increasing number of precision instruments, the demand for precision parts is also increasing. At present, for processed high-precision products, it usually relies on manual bonding of simple calibration fixtures, but the efficiency is very low. Even if it is realized in terms of efficiency and scrap rate, it will require extremely high costs. Therefore, some simple auxiliary devices need to be developed to improve the accuracy and efficiency of manual work. [0003] Chinese patent (publication number CN103721908A) provides a manual heavy-duty rotary workbench with elastic positioning of a ball-end cylinder guide rod, which includes a workbench base, a rotating table, a central shaft, supporting rollers, tracks and an elastic positioning device. The elastic positioning device is composed of a seat cover, a guide rod and a spring. The guide rod is a ball-t...
