Automatic grinding machine tool for mechanical watch rotor

Abstract

The invention relates to an automatic grinding machine tool for a mechanical watch rotor. The machine tool can automatically charge, process and discharge the mechanical watch rotor, thus improving the working efficiency and reducing the labor intensity and labor cost. According to the technical scheme, the automatic grinding machine tool for the mechanical watch rotor comprises a machine body of which the middle part is fixedly equipped with a horizontal worktable, a pneumatic expansion clamp which is vertically mounted on the top surface of the middle part of the worktable, at least one grinding assembly which is mounted on the machine body at the rear side of the worktable and is positioned above the pneumatic expansion clamp, a feeding mechanism which is mounted on the worktable at the front side of the pneumatic expansion clamp, a discharging mechanism which is mounted on the worktable at the rear side of the pneumatic expansion clamp and is used for removing a workpiece from the pneumatic expansion clamp and then conveying to a collecting rack, and a control unit which is connected with the feeding mechanism, the discharging mechanism, the pneumatic expansion clamp and the grinding assembly and used for controlling the action of the feeding mechanism, the discharging mechanism, the pneumatic expansion clamp and the grinding assembly.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to an automatic grinding machine tool for machining pendulums of mechanical watches. Background technique [0002] The pendulum, also known as the pendulum, is the half-moon-shaped centrifugal block of the self-winding watch. Most of them are made of metal plates processed into semicircles, and are usually installed on the central bearing on the back of the movement. In a self-winding mechanical watch, the basic power of the movement is the gravity of the pendulum. The gravity of the pendulum keeps the center of gravity downward when it is still, and it is converted into rotation under the constraint of the axis when it is in motion, so that the movement wind up. [0003] The construction and material of the oscillating weight play a decisive role in the operational efficiency of the automatic winding. Because pendulums require extremely precise gravity, most pendulums today...

Problems solved by technology

[0004] In the existing production process, the above-mentioned grinding work is generally completed by workers on the grinding machine. Every time grinding needs to manually pick and place the workpiece, the work efficiency is low and the labor intensity is high, especially some pendulums have more than two needs. When grinding the surface, the speed is slow and needs to be improved
