Abstract

The invention discloses a hobbing cutter rest rotating device capable of locating accurately. A round hole is arranged on the upper end face of a shell (1), and the inner wall of the round hole is provided with an annular table raised inward; a plane bearing (12) is arranged on the annular table, and the plane bearing (12) is provided with a rotating piece (10); a center fixing piece (6) is arranged in the rotating piece (10), and the lower part of the center fixing piece (6) is fixedly provided with a worm gear (13) which is in gear transmission with a screw (16) arranged in the shell (1); the middle of the center fixing piece (6) is provided with an inner hole, and an encoder is fixedly arranged in the inner hole; an annular step is arranged above the through hole of the rotating piece (10), a centering plate (9) is arranged in the annular step, and the center of the centering plate (9) is fixedly provided with a center rod (7); and the center rod (7) passes through the inner hole, and the lower end of the center rod (7) is connected with the encoder (15) through a coupling (8). In the invention, the hobbing cutter rest rotating transmission mechanism is restructured, the one-stage transmission is used, and the encoder is arranged at the tail end of the rotating device, thereby enhancing the rotating accuracy greatly at the same time. The hobbing cutter rest rotating device is simple in structure, easy to realize and reliable to work.

Description

technical field [0001] The invention relates to a cylindrical gear processing machine tool, in particular to a gear hobbing tool holder turning mechanism, in particular to a gear hobbing tool holder turning device capable of accurate positioning. Background technique [0002] As we all know, gear hobbing machines are equipped with hobbing tool holders, which need to be rotated during the cutting adjustment process. Modern gear hobbing machines have higher and higher requirements for the accuracy of tool holder rotation. Users hope that this adjustment process can be done in one step without secondary adjustments. Avoid scrapping trial cuts. Most of the CNC gear hobbing machines that have appeared in the market use two-stage transmission to realize the rotation of the tool holder, and are equipped with 6 or 8 small oil cylinders to realize the clamping of the rotary device of the hobbing tool holder. Due to the long transmission chain and the low precision of the end transmi...
