Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The radial distance adjustable multi-axis drill of the present invention has a structure such as figure 1 As shown, the drill housing is included, and the drill housing includes a cylindrical upper shell 11 and a circular lower cover 2, and a plurality of fastening screws 1 are passed between the cylindrical upper shell 11 and the circular lower cover 2. Threaded connection; the center in the drill housing is vertically provided with a one-axis 10, and four radial distance adjustment devices are symmetrically arranged in the drill housing according to the direction from the first axis 10 to the inner wall of the drill housing.

[0026] A plurality of holes are evenly arranged on the edge of the circular lower cover 2 , and a plurality of fastening screws 1 pass through the holes provided on the circular lower cover 2 and threadedly con...

Abstract

The invention discloses a span-adjustable type multi-shaft borer. The span-adjustable type multi-shaft borer comprises a borer shell, wherein the borer shell comprises a cylindrical upper shell and a round lower cover, the cylindrical upper shell is in threaded connection with the round lower cover through multiple fastening bolts, a first shaft is vertically arranged in the center of the borer shell, and four span-adjustment devices are symmetrically arranged in the borer shell in the direction from the first shaft to the inner wall of the borer shell. The span-adjustable type multi-shaft borer solves the problems that according to an existing adjustable multi-shaft borer, the adjustment range is narrow, the cutting force is small, and the cutting hole diameter is small.

Description

technical field [0001] The invention belongs to the technical field of machining and manufacturing equipment for mechanical parts, and relates to a drill, in particular to a multi-axis drill with adjustable radial distance. Background technique [0002] Hole processing is one of the most important processes in metal cutting, accounting for more than 30% of all metal cutting processes. Improving the efficiency of drilling has obvious effects on improving the overall processing efficiency of parts. [0003] At present, there are two main methods of using mechanical devices to improve drilling efficiency. One is to use a multi-axis drilling machine, and the other is to use an ordinary drilling machine with a multi-axis drill. Most of the multi-axis drilling machines used are fixed, and the drilling axis cannot be adjusted, which is suitable for mass production; there are also adjustable multi-axis drilling machines, but the investment is relatively large for small enterprises. ...
