Problems solved by technology
[0002] The positioning of the round table with eccentric holes, the existing technology uses four-jaw or three-jaw chucks for positioning. Since the outer edge of the round table is relatively smooth, the round table is easy to rotate in the chuck, resulting in inaccurate radial positioning and cannot ensure subsequent processing.

The invention provides a positioning device of round table with eccentric hole making radial positioning of the round table accurate and ensuring quality of subsequent processing. It comprises a table panel and a round table with eccentric hole. It is characterized in that the table panel is tightly connected with a core rod clamping head, the clamping head end of the core rod clamping head is installed with core rod and is fastened by an adjusting bolt, the core rod is pointed to the round table, the table panel is opened with a positioning hole with diameter identical to that of the round table, the round table is provided into the positioning hole, diameter of the core rod is the same with that of the eccentric hole, and the core rod penetrates through the eccentric hole.
Description
technical field [0001] The invention relates to the technical field of a material positioning device structure, in particular to a positioning device of a circular platform with an eccentric hole. Background technique [0002] The positioning of the round table with eccentric holes, the existing technology uses four-jaw or three-jaw chucks for positioning. Since the outer edge of the round table is relatively smooth, the round table is easy to rotate in the chuck, resulting in inaccurate radial positioning and cannot ensure subsequent processing. . Contents of the invention [0003] In view of the above problems, the present invention provides a positioning device for a round table with an eccentric hole, which makes the radial positioning of the round table accurate and ensures subsequent processing. [0004] The positioning device of the round table with eccentric hole, its technical scheme is as follows: it includes a platen, a round table with eccentric hole, it i...
