Abstract

The invention discloses a multi-spindle tool for machining a complex thread combined workpiece. The multi-spindle tool comprises a swing arm support, a gear box fixed to the top end of the swing arm support, a gear set arranged in the gear box, driving shafts and driven shafts partially extend into the gear box and connected with corresponding gears, screw tap assemblies connected to the bottom ends of the driven shafts and a screw tap lifting driving assembly, each screw tap assembly comprises a fixed-position screw tap assembly and a movable-position screw tap assembly, the distance betweenthe bottom end of the fixed-position screw tap assembly and the thread machining face of the top end of the workpiece to be machined is smaller than the distance between the bottom end of the movable-position screw tap assembly and the thread machining face of the lower end of the workpiece to be machined, and each movable-position screw tap assembly is connected with the corresponding screw tap lifting driving assembly to achieve lifting driving. Threads with different spiral directions and different screw pitches and threaded holes with different hole surface heights can be synchronously machined, one-step machining is achieved, and operation is easy and rapid.

Description

technical field

[0001] The invention relates to the technical field of multi-axis devices, in particular to a multi-axis device used for processing complex threaded combined workpieces. Background technique

[0002] Multi-spindle drill, commonly known as multi-spindle drill, multi-spindle drill or multi-spindle head, is a new type of hole processing equipment, which is widely used in drilling and tapping of porous parts in the machinery industry. However, the existing multi-axis devices can only process threaded holes of a certain specification synchronously, and cannot simultaneously process threaded holes with different helical directions and pitches, and threaded holes with different hole surfaces. If you need to process different helical directions and different pitches Threaded holes with different hole surface heights require multi-step processing, which is cumbersome to operate and prone to errors in processing.
