Problems solved by technology

[0003] When grinding holes, generally the workpiece cannot be rigidly clamped, because this may destroy the position of the original center hole. Therefore, it is often necessary to hold the workpiece and grind the hole at one end, and then grind the hole at the other end; this operation is inefficient. , high labor intensity

Abstract

The invention discloses a double-headed hole-grinding machine. The double-headed hole-grinding machine is used for grinding center holes of shafts and comprises a main power head, a secondary power head and a clamp, a magnetic magnetic-plywood with certain elasticity is installed in the clamp, a workpiece is clamped into a clamp body, the workpiece is restrained by toughness in the radial direction and restrained in the tangent direction, so that the workpiece does not rotate during hole-grinding, and the center holes are not enabled to deviate an original position due to radial external force; and meanwhile, the power heads at the two ends drive hole-grinding needles to rotate at the same time, and a function that holes are ground at the two ends at the same time is realized.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a double-head grinding machine. Background technique [0002] For shaft processing, generally, the center hole must be drilled at both ends. This center hole will be used as a positioning reference in the subsequent process. Therefore, the accuracy of the center hole is very important; in the subsequent processing, especially after heat treatment, the center hole The hole is often affected, therefore, the center hole is drilled. [0003] When grinding holes, generally the workpiece cannot be rigidly clamped, because this may destroy the position of the original center hole. Therefore, it is often necessary to hold the workpiece and grind the hole at one end, and then grind the hole at the other end; this operation is inefficient. , High labor intensity. Contents of the invention [0004] In order to solve the above problems, the object of the present invention i...
