Automatic Clamping and Relaxing Mechanism for Small Bracket of Hobbing Machine

Abstract

The invention relates to an automatic clamping and loosening mechanism for the small bracket of a hobbing machine. The automatic clamping and loosening mechanism comprises a bed body and a cutter frame mounted on the track of the bed body, wherein the cutter frame slides along the main shaft direction of the cutter frame, a push plate is fixedly connected onto the end part of the cutter frame, a bearing seat supported by the push plate is arranged on the end part of the push plate extending out of the bed body, no less than one piece of guide rod for guiding and supporting the small bracket is arranged on the bearing seat, an oil cylinder is fixedly arranged on the small bracket, and the piston rod end of the oil cylinder is fixedly connected with the bearing seat. According to the automatic clamping and loosening mechanism, the cutter frame moves along the main shaft direction of the cutter frame to drive the push plate to move, the bearing seat and the small bracket on the bearing seat are pushed by the push plate to rotate, after a hobbing cutter is mounted and before the hobbing cutter is detached, a control oil cylinder is used for automatically moving the small bracket into an appointed position to be tightly locked with the small bracket, thus the time and labor force are saved, the automatic clamping and loosening mechanism has excellent safety performance, the adjustment precision and processing efficiency of the small bracket can be improved, and the purpose of improving the automated extent of the hobbing machine is achieved.

Description

technical field [0001] The invention relates to a gear hobbing machine component, in particular to an automatic clamping and releasing mechanism for a small bracket of a gear hobbing machine. Background technique [0002] After the hob is installed on a large-scale ordinary gear hobbing machine or a CNC gear hobbing machine, it is necessary to manually move the bracket with the small bracket to the designated position, and then manually push the small bracket to the corresponding position or install the small bracket in the corresponding position through the spreader , so that the main shaft of the small bracket is tightly connected with the hob guide rod, and then lock the hob with the lock nut. When removing the hob, first loosen the lock nut, and then move the small bracket to the corresponding position , slide the small bracket onto the corner bracket, and then manually pull the bracket to the 90° position or hang the small bracket through the bed through the spreader.

[0002] After the installation of the hob is completed on a large-scale ordinary gear hobbing machine or a CNC gear hobbing machine, it is necessary to manually move the bracket with the small bracket to the specified position, and then manually push the small bracket to the corresponding position or install the small bracket at the corresponding position through the spreader , so that the main shaft of the small bracket is tightly connected with the hob guide rod, and then lock the hob with the lock nut. When removing the hob, first loosen the lock nut, and then move the small bracket to the corresponding position , slide the small bracket to the corner bracket, and then manually pull the bracket to the 90° position or hang the small bracket through the bed with a spreader. Installing the lock nut and moving the small bracket is not only time-consuming and laborious, but also poor in safety. Moreover, it affects the adjustment accuracy and processing efficiency of the small bracket
