Abstract

The invention provides a nut internal thread grinding device with a replaceable grinding rod. The internal thread grinding device with the replaceable grinding rod comprises a headstock 1, an internal thread grinding tool 3, the grinding rod 4, a grinding wheel carriage base 5, a grinding wheel carriage rotary drum 6, a supporting board feeding device 7, a supporting board 8, a workbench 9, a lathe bed 10 and a grinding tool finishing device 11. The workbench 9 is arranged on the lathe bed 10 and the headstock 1, the grinding tool finishing device 11 and the grinding wheel carriage base 5 are arranged on the workbench 9; the headstock 1 is used for driving a workpiece with the internal thread characteristic to rotate and the grinding wheel carriage base 5 and the grinding wheel carriage rotary drum 6 can relatively rotate so that a spiral angle required by grinding of internal threads can be obtained; the supporting board feeding device 7 can drive the supporting board 8 to move and drive the internal thread grinding tool 3 to move through the grinding rod 4. Through replacement of the grinding device and adjustment of the position of the grinding rod, nuts of various lengths can be ground on one device, the machining range is enlarged, the machining efficiency and flexibility of the internal threads of the nuts can be improved, and particularly, an ultra-long nut can be ground.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, in particular to a nut internal thread grinding device with a replaceable grinding rod. Background technique [0002] The ball screw pair has the characteristics of high positioning accuracy, high transmission efficiency, good synchronization, and long service life. It is widely used in the fields of CNC machine tools, precision instruments, high-precision measuring instruments, and automated production lines. As the key part of the ball screw transmission, the ball nut determines its operating characteristics to a large extent. With the rapid development of automation control technology and the widespread application of industrial manipulators, ball screw pairs have an increasing demand for processing nuts of various lengths, especially super-long nuts. The existing nut grinding device lacks flexibility and is uneconomical for processing multiple varieties. Therefore, it is neces...
