For the hard clamping mode, that is, the cladding cutter rod is not allowed to swing, and the milling cutter rod is mounted to the gripping mechanism to press the milling tool rod, the hard clamping mode on the accuracy of the machine debugging The positional error between the permissible milling cutter rod and the pressing mechanism is very small, otherwise it is easy to scratch the milling rod, and the wear of the cartridge is severe, or because the position error is more It is highly caus...

AI Technical Summary

Problems solved by technology

[0002] The milling cutter rod is fixedly inserted in the clamping mechanism during the milling process. The clamping mechanism is equipped with a collet for clamping the milling cutter rod. The traditional clamping mechanism is a clamping method for the milling cutter rod It is a rigid clamping method, which means that the clamped milling cutter rod is not allowed to swing. After the milling cutter rod is installed on the machine, the milling cutter rod is pressed by the pressing mechanism. The rigid clamping method has a great influence on the accuracy of machine debugging. The requirements are extremely high, and the allowable position error between the milling cutter rod and the holding mechanism is very small, otherwise it is easy to scratch the milling cutter rod when pressing the milling cutter rod, the collet wears seriously, or because the position error is large The large size leads to substandard processing accuracy, which further leads to low precision and low yield of finished milling cutters, which cannot meet modern production needs.

[0003] In the existing milling cutter processing equipment, a rotating disk is usually installed, and the rotation of the rotating disk drives the clamping device to rotate to the preset station. However, the rotation accuracy of the rotating disk is relatively low, and it is impossible to make the clamping device Accurately stop to the specified position, the position error of each stop action, after many times of accumulation, the error is getting bigger and bigger, the machining accuracy of the milling cutter is low, at this time it is necessary to re-adjust the machine, frequent machine adjustment leads to low work efficiency, high labor cost

[0004] In the existing milling cutter processing equipment, the meshing between gears is rigid meshing, which is prone to tooth damage, resulting in serious gear wear, short service life, and high maintenance costs for processing equipment

Moreover, the meshing accuracy of traditional gears is not high, and slipping will occur, which cannot achieve effective transmission, and the transmission effect is poor
