Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of deep hole machining, and relates to a deep hole cutter self-weight deformation compensation method. BACKGROUND

[0002] There are a large number of valve body parts in the fields of aviation, aerospace, ships and the like, and oil way hole systems are complex, so multiple angle deep holes need to be machined on the valve body parts. Deep hole cutters are used for multi-axis positioning deep hole machining of the valve body parts on a machine tool. Since the axial length of the deep hole cutter is significantly longer than that of a general cutter, the deep hole cutter is deformed under the action of gravity, so that the actual cutter head position of the deep hole cutter deviates from the theoretical cutter head position, and the cutter head position of the deep hole cutter deviates under the action of gravity, so that the deep hole cutter cannot smoothly enter the deep hole on the valve body part, and in severe cases, the deep hole cutter and the valve body part collide, causing the deep hole cutter to break and the valve body part to be damaged.

[0003] Due to the influence of the self-weight deformation of the deep hole cutter, in order to ensure that the deep hole cutter can smoothly enter the deep hole orifice, the cutter head of the deep hole cutter is usually manually guided and adjusted to align the deep hole orifice by the worker, which is difficult to operate and has a certain danger.

[0004] Therefore, in view of the defects that the existing deep hole cutter cannot smoothly align the deep hole orifice after being deformed under its own weight and the operation of guiding and adjusting the cutter head position of the deep hole cutter is tedious, the application discloses a deep hole cutter self-weight deformation compensation device and a compensation method.
