Deep Hole Bottom Grinding Tools

Abstract

The invention discloses a deep hole bottom surface grinding tool. The deep hole bottom surface grinding tool comprises a grinding bar, a grinding head, an elastic piece and a grinding sleeve. The grinding head is located at one end of the grinding bar and can incline in four mutually-perpendicular direction of the axis of the vertical grinding bar, and the other end of the grinding bar is inserted inside the grinding sleeve along the axial sliding set distance of the grinding bar. The elastic piece is fixedly arranged inside the grinding sleeve, and one end of the grinding bar abuts against one end of the elastic piece. The deep hole bottom surface grinding tool can guarantee the close adhesion between the grinding head and a grinded surface and meanwhile guarantee the grinding strength, can be mounted on a machining center for grinding operation, is particularly applicable to processing parts with high flat roughness and flatness requirements at the bottom of deep holes, can achieve processing even when a grinding plane is larger than a hole orifice, can perform interpolation motion according to the contour of the plane through the machining center, can perform self-rotation to achieve grinding operation and is simple in structure and high in grinding precision and grinding speed.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a deep hole bottom grinding tool. Background technique [0002] This grinding tool is suitable for processing parts with the following characteristics: the diameter of the hole is small and the hole is deep, but the surface roughness and flatness of the hole bottom are required to be high. After ordinary turning and milling, the surface roughness of the hole bottom is relatively large. Abrasive tools must be used for grinding. [0003] Common grinding tools have the following defects when processing such parts: because the orifice is small and the hole is deep, the grinding tool needs to be ground deep into the hole, so the diameter of the grinding rod must be smaller than the orifice. If the diameter of the grinding rod is too small, its rigidity cannot be guaranteed, the vibration will be larger during the grinding process, the grinding effect will be poor, and the entire plane cannot be pro...
