Embodiment Construction

[0025] Instructions attached Figures 1 to 8 The structure of the large-hole fine boring tool is shown as an example, but it does not constitute a limitation on the claims. The simplified drawing method is used in the figure, which is only used for clear expression and does not represent the processing structure of the real product.

[0026] The term names used in the description of the examples may contain specific structures or characteristics, but are only used to express the technical conditions of the examples, and shall not limit the technical solutions required by the present invention.

[0027] As a cutting tool design, first, you must find an optimal structure type; second, choose the material and angle of the cutting tool reasonably; finally, continue to improve in practice. Only in this way can qualified and satisfactory cutting tools be designed, and the same is true for large-hole fine boring tools.

Abstract

The invention discloses a large-hole fine boring device. The large-hole fine boring device comprises a fine boring cutter and a force application part, wherein the fine boring cutter is radially positioned in a floating mode on the boring bar cutter side, and the force application part acts on the fine boring cutter to press the fine boring cutter against a guide surface on the cutter side, so that the friction force between the fine boring cutter and the cutter side is no less than the gravity of the fine boring cutter. By the aid of the large-hole fine boring device, the circular degree of formed holes can be guaranteed.

Description

technical field [0001] The invention relates to a fine boring device for machining large holes. Background technique [0002] The current national standard stipulates that the maximum machining aperture of fine boring cutter for jig boring machine is φ310mm. However, in actual processing, boring with a large hole size of φ360mm-φ750mm is often encountered, and the hole above φ360mm is called a large hole here. It should be noted that there is currently no standard definition for large holes, but the concept has already existed in this field. For different processing objects, some processing larger than φ150mm is also called large hole processing. [0003] For large hole machining, if the imitation design is directly used, the hole after boring will appear out of round (oblate, or out of roundness) phenomenon under the action of the gravity of the floating fine boring tool body, and the resulting hole The lower part of the large hole will be larger, ranging from 0.06mm to 0...
