Numerically-controlled multi-station composite processing special machine tool for valve body of butterfly valve

Abstract

The invention relates to a numerically-controlled multi-station composite processing special machine tool for a valve body of a butterfly valve. The numerically-controlled multi-station composite processing special machine tool comprises a base, a worktable, a pressing fixture and a plurality of processing devices, wherein the worktable is arranged on the base and adopts a multi-station indexing rotary worktable, the pressing fixture is arranged on the worktable and comprises a fixture body, pressing devices and a rotary oil separator, the pressing devices are arranged on the fixture body and correspond to each station of the worktable, the rotary oil separator is positioned at the center of the fixture body, the processing devices are arranged around the worktable according to the sequence of processing procedures, and each processing device corresponds to the corresponding station. The numerically-controlled multi-station composite processing special machine tool for the valve body of the butterfly valve has the advantages that the processing efficiency is high; the processing of multiple working procedures can be completed by one-time clamping, the labor intensity of an operator is decreased, the production cost is reduced, the processing accuracy of a product is high, and the requirement of scaled production of large-batch workpieces is met.

Description

technical field [0001] The invention relates to a composite processing machine tool, in particular to a numerical control multi-station composite processing machine tool used for a butterfly valve body. Background technique [0002] CNC machine tools are indispensable parts processing equipment in the entire machinery industry. High processing accuracy, high efficiency and low cost have always been the basic requirements of CNC machine tool users for machine tool products. as attached figure 1 When the butterfly valve body shown is processed by the existing CNC machine tool, after the workpiece is clamped once, it is necessary to gradually change the tool from the tool magazine and the conversion of the spindle head and the movement of the manual operation table to realize the multi-position of the workpiece. One process is processed, and another workpiece can be processed only after one workpiece is processed. This kind of production efficiency is low, it is not suitable f...

Problems solved by technology

as attached figure 1 When the butterfly valve body shown is processed by the existing CNC machine tool, after the workpiece is clamped once, it is necessary to gradually change the tool from the tool magazine and the conversion of the spindle head and the movement of the manual operation table to realize the multi-position of the workpiece. One process is processed, and another workpiece can be processed only after one workpiece is processed. This kind of production efficiency is low, it is not suitable for the processing of mass products, and the price is relatively expensive, and the long tool change time leads to low processing efficiency. The labor intensity of workers is high, and the machining accuracy cannot be guaranteed, which cannot meet the needs of large-scale production of workpieces.
