HOLLOW CYLINDRICAL PART FASTENING APPARATUS

摘要

FIELD: metal working, namely apparatuses for fastening hollow cylindrical part. ^ SUBSTANCE: apparatus includes tie rod arranged in central opening with possibility of reciprocation motion along axis housing of apparatus and spring-loaded plungers arranged in radial openings with possibility of axial motion by action of cam surfaces of tie rod. On housing there is end basing resting surface; holder is mounted on tie rod while sum of two length values of plunger and tie rod diameter at time moment of part fastening is equal to nominal inner diameter of part. Radial openings and plungers of second row are shifted along circle relative to openings and plungers of first row; ends of plungers are spherical ones. ^ EFFECT: possibility for deformation-free centering and clamping hollow cylindrical part. ^ 3 cl, 3 dwg
