Problems solved by technology

During milling, the two ends of the cylindrical workpiece need to be milled with symmetrical planes (that is, flattened). In the process of milling and flattening with conventional fixtures, since the positioning datum of the cylindrical workpiece is inconsistent with the design datum, and repeated positioning is required, Its axial dimension, flat thickness dimension, symmetry and parallelism are difficult to meet the requirements

Abstract

The invention discloses a cylindrical workpiece end flat-milling and clamping device which comprises a bottom plate, a V-shaped groove sizing block, a V-shaped groove pressure head, a driving threaded rod and a positioning block. A first vertical plate and a second vertical plate are fixedly arranged on the upper side of the bottom plate. The V-shaped groove sizing block is fixedly arranged on one side of the first vertical plate. The driving threaded rod is arranged on the second vertical plate. The V-shaped groove pressure head is hinged to one end of the driving threaded rod. A circular handle is fixedly mounted at the other end of the driving threaded rod. The positioning block and a support are fixedly arranged on the upper side of the bottom plate and located between the V-shaped groove sizing block and the V-shaped groove pressure head. A pressing shaft used for rapidly and tightly pressing a workpiece is mounted in an unthreaded hole in the middle of the support in a sliding mode. An elastic element is arranged between the end of the pressing shaft and the support. The cylindrical workpiece end flat-milling and clamping device has the following characteristics of quick positioning, good positioning accuracy, high machining precision, reasonable design, simple structure and convenient clamping.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a simple clamping device, in particular to a clamping device for symmetrically milling and flattening the end of a cylindrical workpiece. Background technique [0002] Such as figure 1 A cylindrical workpiece is shown, and the cylindrical workpiece must be processed through three processes of turning, milling and drilling. During milling, the two ends of the cylindrical workpiece need to be milled with symmetrical planes (that is, flattened). In the process of milling and flattening with conventional fixtures, since the positioning datum of the cylindrical workpiece is inconsistent with the design datum, and repeated positioning is required, Its axial dimension, flat thickness dimension, symmetry and parallelism are difficult to meet the requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the abo...
