Embodiment

[0055] Taking a CNC machine tool as an example, the eccentricity problem after installation of the boring tool is corrected by making an eccentric adapter sleeve. The specific implementation method is as follows, as follows: Figure 4 Shown:

[0056] (1) Measure the diameter of the tool mounting hole of the tool mounting seat 1 of the machine tool to be Φ20mm;

[0057] (2) After the boring tool 5 with a diameter of Φ4mm is mounted on the tool handle by clamping spring 3, the boring tool 5 together with the tool handle is installed on the machine tool, and the axis of the boring tool 5 deviates from the center of the machine tool spindle by making a watch. The maximum eccentricity is 2mm;

[0058] (3) According to the principle of 20-2×2>X3, the diameter X3 of the first inner hole 2-1-1 of the eccentric device 2 is determined to be Φ12mm;

[0059] (4) According to the principle of X2-Φ12>5 and the standard of the clamp spring 3 used for clamping the machine tools, determine t...

Abstract

The invention belongs to the technical field of machine tools free of a Y-axis control system, and particularly relates to a device and method for eliminating eccentricity of a tool and a main shaft of a machine tool. The device comprises an eccentric device and a nut. The eccentric device comprises a first cylindrical section and a second cylindrical section. The first cylindrical section is provided with a first inner hole in the axial direction. An eccentric distance exists between the first inner hole and the first cylindrical section. The eccentric distance is not smaller than the maximumvalue of the distance that the tool of the machine tool deviates from the center of the main shaft. The second cylindrical section is provided with a second inner hole in the axial direction. The second inner hole and the first inner hole are coaxial and communicate with each other. The second inner hole is a conical hole. The small end of the second inner hole communicates with the first inner hole, and the diameter of the small end of the second inner hole and the diameter of the first inner hole are the same. The outer surface of the second cylindrical section is provided with an externalthread, and the second cylindrical section is in threaded connection with the nut through the external thread. A through hole is formed in the center of the nut. By means of the device and method foreliminating the eccentricity of the tool and the main shaft of the machine tool, the eccentric problem of the tool and the center of the main shaft can be solved, and the machining quality of a workpiece is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of machine tools without a Y-axis control system, and in particular relates to a device and method for eliminating eccentricity between a machine tool tool and a spindle. 【Background technique】 [0002] At present, machine tools without a Y-axis control system often encounter the problem of eccentricity between the tool and the spindle, and the eccentricity problem will seriously affect the processing quality of the parts. Although there are some measures to alleviate the impact of the eccentricity problem at present, the degree of mitigation is limited and the effect is not satisfactory. Therefore, there is an urgent need for a device and method that can eliminate the eccentricity of the machine tool tool and the spindle. 【Content of invention】 [0003] In order to solve the problems existing in the prior art, the object of the present invention is to provide a device and method for eliminating the ecce...
