Problems solved by technology

Frequent tapping is not conducive to ensuring the accuracy of the machine tool and seriously affects the quality of the processed parts
Secondly, the installation and disassembly of the three claws is very cumbersome. For the processing of parts that need to be frequently replaced with different specifications, it seriously affects the processing efficiency and affects the company's profitability.
Finally, the three-jaw clamping adopts three-point contact, which is not conducive to the alignment of the parts, which in turn affects the processing of the parts
And when the clamping force is too large, it is easy to pinch the surface of the part

Abstract

The invention relates to a fast changing fixture for a six-axis air floating grinding machine. According to the structure of the fast changing fixture, a machine tool spindle and a disc chuck clamp are connected in a fastened mode through bolts to fix the position of the disc chuck clamp; a back cap is connected with the disc chuck clamp through threads;the back cap and a clamping spring are fixedin a clearance fit mode; and a machined part and a clamping spring inner hole are fixed in a clearance fit mode. By adjusting and disassembling the connecting bolts between the disc chuck clamp and the machine tool spindle, fast installation, alignment and replacement of the machined part and the machine tool spindle are guaranteed.

Description

technical field [0001] The invention relates to a tooling for quickly changing clamping objects of different sizes, in particular to a quick-change fixture for a six-axis air-floating grinder, which is suitable for the six-axis air-floating grinder to finish machining parts of outer circles and inner holes. Background technique [0002] At present, countries are increasingly competitive in information industry, aerospace industry, military industry, electronics industry and other fields. As these high-tech fields are increasingly developing towards high speed, high efficiency, precision, lightweight and automation, the requirements for precision machine tools are also increasing. come higher. Modern precision machine tools are developing in the direction of ultra-precision, high speed and high power. Therefore, there is an increasing demand for fixtures that can be quickly installed, replaced, and aligned for precision machine tools such as six-axis air-floating grinding ma...
