Chuck device for automatically cleaning auxiliary shaft iron chips

Abstract

The invention relates to a chuck device for automatically cleaning auxiliary shaft iron chips. The chuck device comprises a chuck shell, a pushing rod assembly, a rotating following converter, a spring, an outer connected converter, a coolant assembly and an air intake assembly, the chuck shell is clamped by a clamping motor and rotates along with the clamping motor, the pushing rod assembly is arranged in the chuck shell, one end of the pushing rod assembly is connected to a to-be-machined product in a propped mode, the rotating following converter is arranged at the tail of the chuck shell,and the two axial ends of the spring are correspondingly connected to the pushing rod assembly and the rotating following converter. Compared with the prior art, the chuck device is used for being mounted on a precise digital-controlled machine tool, a cooling device is connected into the special chuck device, during inner machining of an auxiliary shaft hole, cooling can be conducted on a machining position of a cutter in real time, chip winding due to the high temperature is avoided, after auxiliary shaft machining finishing, an inner pushing rod in a special chuck of the chuck device can push the iron chips left in the auxiliary shaft out, the air intake assembly can lead air pressure in, the iron chips in the device are effectively cleaned, and the chance of the secondary shaft iron chips clamping the product is greatly reduced.

Description

technical field [0001] The invention relates to a collet device, in particular to a collet device for automatically cleaning iron filings of a secondary shaft. Background technique [0002] The full name of the heart-moving machine is a heart-moving CNC lathe, and it can also be called a headstock mobile CNC automatic lathe, an economical turning-milling compound machine tool or a slitting lathe. It belongs to precision processing equipment, which can complete compound processing such as turning, milling, drilling, boring, tapping, engraving and so on at the same time. It is mainly used for batch processing of precision hardware and shaft special-shaped non-standard parts. When feeding, firstly, the blank to be processed is clamped to the auxiliary shaft by the manipulator, and then moved to the fixture by the auxiliary shaft for processing. [0003] At present, the extensive development of shaft products in the automotive industry has made the application of core walking m...

Problems solved by technology

[0004] The pinching of the product by the iron filings of the auxiliary shaft of the core walking machine is one of the most important reasons for product failure and scrapping. The main reason for the residue of iron filings is: the temperature of the product to be processed is too high during high-speed processing, The adhesion of the iron filings is enhanced, causing the generated iron filings to enter the chuck of the auxiliary shaft of the core walking machine, resulting in pinching of the product to be processed
