Multi-shaft high-speed numerically controlled lathe

Abstract

The invention relates to a multi-shaft high-speed numerically controlled lathe. The multi-shaft high-speed numerically controlled lathe comprises a slant bed lathe body which is provided with a main machine and a slant bed body assembly. A four-station electric tool carrier and a lathe spindle are mounted on the slant bed body assembly, wherein an additional machining shaft system assembly which is arranged perpendicular to the lathe spindle is further mounted on a spindle box; a second fixed seat is arranged on the lateral side of the slant bed body assembly on the main machine; and an auxiliary centering assembly opposite to the lathe spindle is mounted above the second fixed seat. According to the multi-shaft high-speed numerically controlled lathe provided by the invention, a machining shaft is additionally arranged; on the basis of the original machining shaft which machines an excircle, the additionally arranged machining shaft can perform operations such as chamfering and groove milling simultaneously, so that the production efficiency and the machining precision are greatly improved; the auxiliary centering assembly is a three-finger pneumatic finger, and a guide rail and sliding tables are arranged at the bottom of the three-finger pneumatic finger, so that a cantilever of the centering assembly can be prevented from being overlong, and the stability of the centering assembly is greatly improved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of processing machine tools, in particular to a multi-axis high-speed numerically controlled lathe. [0003] Background technique: [0004] When turning cylindrical workpieces such as motor rotors and other products on the existing CNC inclined bed lathe, the turning process and the chamfering process are carried out separately, and the tool change operation needs to be suspended in the middle, so at least two processes are required to complete the external process. The round machining and chamfering process make the whole machining process cumbersome and complicated, and frequent tool changes are required, which not only reduces the production efficiency but also easily increases the machining error. In addition, in the process of processing, it is necessary to minimize the swing of the workpiece during high-speed rotation to reduce errors. Therefore, an auxiliary centering device is required.

Problems solved by technology

[0004] When the existing CNC inclined bed lathes turn cylindrical workpieces such as motor rotors and other products, the outer circle turning process and the chamfering process are carried out separately, and the tool change operation needs to be suspended in the middle, so at least two processes are required to complete the outer circle. Round machining and chamfering process, which makes the whole machining process cumbersome and complicated, requiring frequent tool changes, which not only reduces production efficiency but also easily increases machining errors

In addition, in the process of processing, it is necessary to minimize the swing of the workpiece during high-speed rotation to reduce errors, so an auxiliary centering device is needed. However, the existing auxiliary centering devices often have too long cantilever and poor stability during use. Cause product processing accuracy is not high
