Automatic feeding and discharging device of numerical control gear hobbing machine

Abstract

The invention relates to the technical field of numerical control machining equipment, and discloses an automatic feeding and discharging device of a numerical control gear hobbing machine. The automatic feeding and discharging device comprises a machine body, a control panel is fixedly installed on the right side of the machine body, a protective door is movably connected to the surface of the front face of the machine body, a clamping assembly is fixedly installed on the inner wall of the machine body, and a bottom box is fixedly installed at the bottom end of the machine body. According to the automatic feeding and discharging device of the numerical control gear hobbing machine, a corrugated pipe stretches out and draws back to drive a baffle to apply force to rotating teeth, so that a to-be-machined part is continuously and effectively fixed; when an inner rod moves to the inner wall of a hollow pipe, a fixing frame installed on the left side of the inner rod compresses the corrugated pipe and a structure to which the corrugated pipe belongs, then the baffle moves to enable a toothed plate to drive the rotating teeth to rotate, the rotating teeth rotate to enable a springback rod to extend, and an inclined rod drives a rotating plate to rotate; and when the rotating plate rotates, touch rods fixed to the rotating plate move upwards to enable air cushion to be extruded and shrunk, at the moment, anti-collision pads are more firmly attached to the to-be-machined part, and then the protective door is closed for machining.

Description

technical field [0001] The invention relates to the technical field of numerical control processing equipment, in particular to an automatic loading and unloading device of a numerical control gear hobbing machine. [0002] technical background [0003] The gear hobbing machine is the most widely used machine tool among the gear processing machine tools. The hobbing machine can cut straight teeth, helical cylindrical gears, worm gears, sprockets, etc., and process straight teeth, helical gears and Gear processing machine tools for herringbone cylindrical gears and worm gears. This machine tool can also process various special tooth-shaped workpieces such as splines and sprockets when using a special hob. [0004] However, the general hobbing machine often has the following two defects in the processing process: [0005] 1. After the workpiece is placed, during the rotation of the equipment, due to the collision of the cutter and the rotation of the workpiece itself, the work...

Problems solved by technology

[0005] 1. After the workpiece is placed, during the rotation of the equipment, due to the collision of the cutter and the rotation of the workpiece itself, the workpiece may shake slightly, which may cause deviations in the processing accuracy and may cause the workpiece to be scrapped;

[0006] 2. In the process of unloading the workpiece, it is necessary to use force to separate the workpiece from the equipment, which is easy to cause hand extrusion, and there are certain safety hazards. In the process of loading, it is necessary to use hands to support it to prevent the workpiece to be processed. Material offset, very troublesome, unable to carry out production work quickly and effectively
