Rotary positioning machining rotary table

Abstract

The invention provides a rotary positioning machining rotary table comprising an angle base. The slope angle of the angle base is equal to an included angle between a bus and an axis of a machined conical cabin segment; the angle base is provided with a rotating disk bottom plate; after a rotating disk is connected with a rotating shaft, the rotating disk is installed on the rotating disk bottom plate through a thrust bearing; a bottom plate stepped hole for installing the thrust bearing is formed in the center portion of the rotating disk bottom plate; evenly-distributed bottom plate locking screw holes are formed in the periphery of the rotating disk bottom plate; positioning holes are further formed in the peripheral line of the rotating disk bottom plate; rotating disk stepped holes for installing the rotating shaft and the thrust bearing are formed in the center of the rotating disk; the positions, opposite to the bottom plate locking screw holes of the rotating disk bottom plate, on the rotating disk are provided with rotating disk locking stepped holes; a rotating disk locking assembly is installed above the rotating disk locking stepped holes; the rotating disk is further provided with a positioning pin hole which corresponds to the positioning holes in the rotating disk bottom plate; a plug pin assembly is installed above the positioning pin hole; a positioning boss is arranged on the middle portion of the rotating disk; the positioning boss is matched with a bottom hole of a machined conical cabin; and threaded rod installing screw holes are evenly distributed in the outer ring of the positioning boss on the rotating disk and used for installing a pressing plate, and the machined conical cabin is fixed.

Description

technical field [0001] The invention belongs to the technical field of non-standard special process equipment, and mainly relates to a rotary positioning processing turntable, which is mainly used for the step plane in the processing cabin section of the angle milling head of the existing processing center. Background technique [0002] At present, the company is responsible for the production of a certain type of cabin shell, which is made of aluminum alloy casting and has high requirements for internal quality and external dimension accuracy. , mouth frame and front and rear end frames, etc., with many windows, thin walls, high precision requirements (IT7-IT8 level), and many processing surfaces. Because the company currently lacks multi-axis processing machines, it often needs to go through multiple processes such as turning, milling, boring, and clamping. Repeated alignment and processing of the first process not only has a large workload, many processing procedures, lon...
