Installing structure of taper shank with attached cutting head

Abstract

The invention relates to an installing structure of a taper shank with an attached cutting head, which is characterized in that: a press cover is fastened and connected at the lower end of the taper shank through a screw, a drive shaft is limited in a cavity formed by the press cover and the taper shank through a boss thereof, installation gap is formed at the connection and installation part of the taper shank and an auxiliary drive shaft; a spring is arranged on a short shaft at the upper end of the drive shaft, and a pull stud is connected with the taper shank through a thread. The installing structure can avoid the situation of shutdown after a sliding pillow of a main shaft receives greater resistance; meanwhile, the spring provides the elastic pre-tightening force for the thread connection part of the pull stud and the taper shank, thereby preventing the situation that a claw of the main shaft can not pull the attached cutting head to the installation position after the pull stud is loose. The installing structure can not only reasonably solve the difficult automatic replacement of the cutting head caused by rigid connection of the taper shank, but also provide the pre-tightening force for the thread connection part, thereby preventing the looseness of the thread of the pull stud, protecting the smooth completion of the replacement action of the attached cutting head of a five-face gantry machining center and simultaneously improving the machining efficiency.

Description

technical field [0001] The invention relates to an installation structure of an additional cutting head taper shank, in particular it is suitable for the installation of the additional cutting head taper shank and belongs to the technical field of mechanical structures. Background technique [0002] With the rapid development of my country's machinery industry, especially the development of heavy industry, there is an increasing demand for high-precision metal processing equipment such as pentahedron gantry machining centers. Pentahedron gantry machining centers are developed on the basis of gantry machining centers. A multi-functional CNC machine tool, through automatic replacement of various additional cutting heads, can realize multi-faceted processing of large mechanical parts. Usually, all or most of the processing procedures of large mechanical parts can be completed in one clamping, thus greatly reducing Improve production efficiency, which can improve work efficiency b...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above shortcomings, thereby providing a flexible connection between the taper shank and the additional cutting head, which solves the problem that the automatic installation of the additional cutting head cannot be completed when the taper shank is not at the same position as the rotation center line of the spindle taper surface At the same time, it also overcomes the situation that the taper shank cannot enter the positioning position after the pull nail is loosened.
