Gear-shaving machine knife quick change mechanism

Abstract

The invention discloses a quick cuter replacing mechanism for a gear tooth shaving machine. A shaving cutter and cutter cushion rings are sheathed on a main shaft, and the cutter cushion rings are positioned on both sides of the shaving cutter. The quick cuter replacing mechanism is characterized in that a spline shaft (11) is sheathed on the outer tip of the main shaft (7) and is tightly fixed by an axial locking screw (12); a spline on the spline shaft (11) is shorter than the spline shaft, and the end of an optical shaft is adjacent to the cutter cushion rings (5); a quick-release cushion ring (3) provided with a spline slot is flexibly sheathed on the spline shaft (11), and spacer pins (10) are arranged on the outer end face of the quick-release cushion ring (3); and the inner diameters of the shaving cutter (4) and the cutter cushion rings (5) are larger than the maximum diameter of the spline shaft (11). The quick cuter replacing mechanism for the gear tooth shaving machine has the advantages of quick cutter replacement, effective looseness prevention, compact structure, convenient operation and high safety and reliability.

Description

technical field [0001] The invention belongs to machine tool components, and in particular relates to a tool changing mechanism on a gear shaving machine. Background technique [0002] As we all know, the razor is an important tool for cutting on the gear shaving machine tool. It is a common process to change the tool in the cutting process, and the quality of the tool changing mechanism directly affects the work efficiency and cutting quality. The tool change mechanism on the traditional gear shaving machine is as follows: figure 1 As shown, it is set with a razor 4 and a cutter washer 5 on the main shaft 7, the cutter washer 5 is located on both sides of the razor 4, the main shaft 7 is a stepped shaft, and the outer end of the main shaft 7 is a screw structure, on the screw Set of nuts 12. In order to lock the razor 4 in place, a spacer 13 is arranged between the nut 12 and the cutter washer 5 . When this knife changing mechanism replaces the razor 4, it is necessary t...

AI Technical Summary

Problems solved by technology

When this knife changing mechanism replaces the razor 4, it is necessary to unscrew all the nuts 12 out of the main shaft 7, and take out the spacer 13, so that the razor 4 can be taken out; Until the spacer 13 is tightly pressed on the cutter washer 5 and the razor 4, therefore, the tool changing mechanism currently used on the gear shaving machine is time-consuming and laborious, and after a period of use, the nut 12 will produce axial displacement, causing the razor 4 to loosen , affecting cutting quality
