Auxiliary tool changing device for machining reverse-side counter bores for automobile parts

Abstract

The invention discloses an auxiliary tool changing device for machining reverse-side counter bores for automobile parts. A spring shell is fixedly connected with a slide rail barrel through a thread,and a tool apron is arranged in the slide rail barrel; the spring shell, the slide rail barrel and the circular tool apron form a hollow sealing cavity, and a spring is arranged in the sealing cavity;balls are annularly and uniformly distributed on the tool apron, and a tool bit is clamped into the balls through a circular groove; and one end of a tool bar is inserted into the tool bit, and the other end of the tool bar is arranged on a tool handle. The structures of the tool bar and the tool bit are improved according to the shape and the function of a reverse scraping tool, and the purposesof automatic tool changing and counter bore reverse scraping are realized in combination with the auxiliary device, so that the machining difficulty for the reverse-side counter bores of large complex parts is lowered, machining for a part of parts which cannot be subjected to machining of reverse-side counter bores is realized, and stable dimensions and high production efficiency are achieved. Meanwhile, the labor force is liberated, and the machining efficiency is increased, and the device further has the characteristics of being low in manufacturing cost, stable in auxiliary tool changing,and long in service life.

Description

technical field [0001] The invention relates to an automatic tool-changing auxiliary device for a back counterbore machining tool of large-scale automobile parts, belonging to the technical field of automobile manufacturing. Background technique [0002] Nowadays, most of the counterbores on auto parts are processed from the reverse side, but when processing large parts, processing from the back requires an additional process. For heavy parts, handling and clamping are very laborious. For some parts with complex structures, there will be processing interference from the back, which will make the processing of the parts difficult to realize or require a huge increase in equipment costs, which makes many small factories sigh. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an auxiliary tool changing device for machining back counterbore of auto parts. [0004] In order to solve the problems of the technologies des...
