Rotary table device for ring workpiece processing

Abstract

PURPOSE: A rotating table device for processing a ring-shaped workpiece is provided to enable a rotating disc to be reliably kept level without an expensive R guide. CONSTITUTION: A rotating table device for processing a ring-shaped workpiece comprises a table supporting unit(40). The table supporting unit comprises a guide rail(41) and a plurality of table support rollers(42). The guide rail is installed on the lower part of the edge of a rotating disc and rotates in a circle form around a central shaft(C). The table supporting roller supports the lower part of the guide rail. If the rotating disc rotates, the table supporting roller makes contact with the guide rail to slide the guide rail.

Description

technical field [0001] The present invention relates to a turntable device for processing ring-shaped workpieces, in particular to a ring-shaped workpiece set to be processed; the turntable supporting device is formed on the edge of the turntable, and is used to rotatably support the central part of the turntable by the central bearing part of the base and make the turntable To maintain the horizontal rotation, the turntable support device includes: a guide rail arranged around the lower part of the edge of the turntable in a ring; a plurality of turntable support rollers slidably support the guide rail under the guide rail. A turntable device for machining a ring-shaped workpiece can be manufactured in which the turntable can be disassembled while maintaining the horizontal state of the turntable without using an expensive conventional R-guide device. Background technique [0002] As a known technology, there are various forms of supporting structures used to support variou...

[0014] However, if the R guide device is used on the turntable device for processing a circular workpiece, not only will the manufacturing cost increase due to the higher cost of the R guide device, but also from the characteristics of the R guide device, the The turntable that is guided and rotated by the R guide device can only be manufactured in one piece, and the manufacture of an integrated turntable will increase the difficulty of manufacturing and handling due to its size, which will increase the cost of device construction

[0015] And, according to the turntable device for processing ring-shaped workpieces in the prior art, a hydraulic stopper (stopper) is usually used to stop the rotating turntable at the index position to be processed, but the hydraulic stopper exists as follows: Problem: Complex structure, difficult to maintain precision, that is, it is difficult to stop the turntable at the corresponding position exactly

[0016] At present, the demand for ring-shaped workpieces such as tower flanges continues to increase, but processing companies cannot meet the rapidly increasing demand for ring-shaped workpieces due to the burden of investing in high-priced equipment
