Abstract

The invention relates to a correcting device for correcting the coaxiality and straightness of a boring bar. The correcting device comprises a base, oblique beams, a top beam, a pressing mechanism anda supporting mechanism, and the supporting mechanism comprises two rolling shafts which are horizontally and parallelly arranged; the circle centers of the two rolling shafts are on the same horizontal line, and the included angle of connecting lines of the circle centers of the two rolling shafts and the boring bar is an acute angle; a correcting mechanism for correcting the coaxiality and straightness of the boring bar is arranged at one side of a fixed connecting rod and comprises a support arm and a dial indicator, a telescopic indicator head of the dial indicator is in contact with the surface penetrating through the axis of the boring bar, the boring bar is rotated, and the coaxiality of the boring bar is corrected by observing swinging of a pointer of a telescopic indicator head. The correcting device is reasonable in structure, convenient to use, capable of conducting automatic correction in advance, high in correcting accuracy, and convenient to operate; the technical problems are solved that in the using process of an existing boring bar, when the boring bar is slightly deformed, a workpiece has a large error, the product quality is influenced, and the enterprise production benefit is influenced. Compared with the prior art, the correcting device has a good market prospect and developing space.

Description

technical field [0001] The invention relates to the technical field of boring machine manufacturing, in particular to a correction device for correcting the coaxiality and straightness of a boring bar. Background technique [0002] The boring machine is the main equipment for processing large box parts. It is a machine tool that mainly uses a boring tool to bore the existing prefabricated holes of the workpiece. Usually the main motion is the rotation of the boring tool, and the movement of the boring tool or the workpiece is the feed motion. It is mainly used to process high-precision holes or complete the finishing of multiple holes at one time. In addition, it can also process other processing surfaces related to hole finishing, such as threading and processing outer circles and end faces. The machining accuracy and surface quality of drilling, milling, and cutting are higher than those of drilling machines by using different tools and accessories. [0003] The boring b...
