Plane milling and boring machine tool rest

Abstract

The invention discloses a plane milling and boring machine tool rest comprises a milling tool bit, a boring tool bit, a ram, a central shaft, an indexing mechanism and a tool rest body. The tool rest body is rotationally connected with the central shaft. The milling tool bit or the boring tool bit is mounted at one end of the tool rest body. The indexing mechanism is fixedly connected with the tool rest body. The milling tool bit comprises a five-axis milling head and a milling head pull rod which are fixedly connected. The boring tool bit comprises a boring tool rest pull rod, a lower-end fluted disc, a boring tool rest and a boring tool bar, wherein the boring tool rest pull rod and the lower-end fluted disc are fixedly connected at the upper end of the boring tool rest, and the boring tool bar is fixedly connected at the lower end of the boring tool rest. By the boring tool rest pull rod, indexing adjustment of the ram in a range of 1-20 degrees can be achieved, simple switch of the milling tool bit and the boring tool bit can be achieved, especially in machining of large workpieces, complex curve face milling, taper hole boring and excircle surface cutting can be completed after one-step mounting, machining efficiency and precision of the large workpieces are increased greatly, repeated positioning errors caused by secondary clamping are avoided.

Description

technical field [0001] The invention relates to a tool holder for a gantry boring and milling machine, in particular to a tool holder for a gantry boring and milling machine capable of milling curved surfaces with five degrees of freedom and boring taper holes. Background technique [0002] With the development of manufacturing technology, the five-axis linkage CNC machine tool system has become the guarantee for solving complex curved surface milling and improving processing efficiency and precision. The five-axis linkage CNC boring and milling machine is widely used in the processing of many large workpieces, such as the processing of large propeller blades. The taper of the inner hole of most large propellers is usually between 1° and 20°. Traditional machining requires the boring of the hole and the milling of the blade surface on a boring machine and a milling machine. The clamping is cumbersome and the positioning accuracy is low.

AI Technical Summary

Problems solved by technology

However, the taper of the inner hole of most large propellers is usually between 1° and 20°. Traditional machining needs to complete the boring of the hole and the milling of the blade surface on a boring machine and a milling machine respectively. The clamping is more troublesome and the positioning accuracy is low.
