Problems solved by technology

[0002] Currently in machining, such as figure 1 and figure 2 As shown, it is often encountered that the eccentric groove 30a needs to be cut on the slender shaft 30. If the length-to-diameter ratio of such parts is ≥ 25, if an ordinary lathe is used to process the eccentric fixture, not only the versatility is poor, because the eccentric groove is in the axial position , and different eccentricity need to replace different eccentric fixtures, and the parts are seriously deformed during the high-speed rotation of the lathe, which affects the processing quality

Abstract

The invention discloses a cutter for machining an eccentric groove, comprising a stand, a motor, a hollow main shaft and a belt pulley, wherein the hollow main shaft is arranged on the stand through a bearing seat and a bearing; the belt pulley is connected with the motor and the hollow main shaft; the hollow main shaft is also provided with a knife holding mechanism; and the stand is also provided with a material clamping mechanism. In the invention, a workpiece is fixed and a knife rotates, therefore the rotational deformation of the workpiece is prevented and machining quality is ensured; and different eccentric grooves can be machined by adjusting the position of the workpiece in an elastic clamping sleeve of the material clamping mechanism, the dislocation of the workpiece and a positioning rod of the material clamping mechanism in a radial direction and the position of the knife positioned on the knife holding mechanism. The invention has good universality, high machining efficiency, and the like.

Description

technical field [0001] The invention relates to a cutting machine for machining eccentric grooves. Background technique [0002] Currently in machining, such as figure 1 and figure 2 As shown, it is often encountered that the eccentric groove 30a needs to be cut on the slender shaft 30. If the length-to-diameter ratio of such parts is ≥ 25, if an ordinary lathe is used to process the eccentric fixture, not only the versatility is poor, because the eccentric groove is in the axial position , and different eccentricity need to replace different eccentric fixtures, and the parts are seriously deformed during the high-speed rotation of the lathe, which affects the processing quality. Contents of the invention [0003] The object of the present invention is to address the above-mentioned shortcomings of the prior art, and provide a cutting machine specially used for machining eccentric grooves, which has the advantages of good versatility, high processing efficiency, and...
