Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Example Figure 1-3 Shown: a single-power boring device with two parallel boring bars whose center distance can be greatly adjusted, including a positioning boring bar 10 and a translation boring bar 11; the positioning boring bar 10 is supported on the first rolling bearing seat fastened to the boring machine table 15 and the second rolling bearing housing 16, the translation boring bar 11 is supported on the third rolling bearing housing 13 and the fourth rolling bearing housing 14 capable of translating along the boring machine workbench, ensuring that the translation boring bar 11 is always parallel to the positioning boring bar 10 during translation. On the outer side of the second rolling bearing housing 16 of the positioning boring bar 10, the first boring bar gear 3 is installed with a key connection. On 10, between the transmission gear...

Abstract

The invention relates to a single-motor two-parallel boring bar boring device with a widely adjustable center distance. A positioning boring bar is supported on two rolling bearing blocks fastened on a boring mill workbench; a translation boring bar is supported on two rolling bearing blocks capable of translating along the boring mill workbench; the positioning boring bar is provided with a boring bar gear and a gear meshed with a boring mill shaft gear in a key joint way, and is provided with a positioning connecting rod in a rolling way; the translation boring bar is provided with a boringbar gear in the key joint way and a translation connecting rod in the rolling way; the two connecting rods are respectively provided with an intermediate shaft gear which is simultaneously meshed with the boring bar gear and a jointed shaft gear in a cantilever rolling way; the jointed shaft gear is simultaneously arranged on the two connecting rods in a rolling way; and the two connecting rods are hinged around the shaft of the jointed shaft gear. The single-motor two-parallel boring bar boring device can simultaneously process two parallel holes with center distance requirement on a conventional single-motor boring mill, and can simplify processing procedure, shorten processing time, improving production efficiency and reducing production cost.

Description

technical field [0001] The invention relates to a boring device matched with a boring machine, in particular to a boring device whose center distance between two parallel boring bars with single power can be greatly adjusted. Background technique [0002] At present, when two holes with center distance requirements are processed on a traditional boring machine, one of the holes is processed first, and then the second hole is processed; when the second hole is processed, a small blank hole needs to be rough-bored, and then Measure the center distance, calculate the error, and adjust the machine tool, and then finish the second hole to meet the requirements of the drawing. This method has many processing steps and low efficiency, which is not conducive to mass production; although it can be easily processed by using combined machine tools and numerical control machine tools, the cost of purchasing these machine tools is very high. Contents of the invention [0003] The obje...
