Self-adaptive auxiliary device for safety protection of engraving clamping force of glasses frame

Abstract

The invention relates to the technical field of safety protection, and discloses a self-adaptive auxiliary device for safety protection of engraving clamping force of a glasses frame. The self-adaptive auxiliary device comprises an electrified coil, wherein a reset spring is movably connected to the right side of the electrified coil, a clamping magnet is movably connected to the right side of thereset spring, a pushing block is movably connected to the right side of the clamping magnet, a clamping block is movably connected to the right side of the pushing block, a pull rod is movably connected to the middle of the clamping block, and a clamping jaw is movably connected to the right side of the pull rod. An upward counter-acting force is applied to a graver through a material, so that the magnitude of current in the electrified coil is adjusted, and the clamping jaw is driven to clamp the material; and after the material is graved, the pressure applied to a piezoelectric material disappears, and the current of the electrified coil returns to normal at the moment, so that the clamping block is driven to move in the direction away from the material, the clamping jaw is driven to loosen the material, and the effect of automatically adjusting the clamping force to the material according to a graving state is achieved.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to an auxiliary device for self-adaptive engraving clamping force of safety protection glasses frames. Background technique [0002] Safety protection has always been the focus of people's attention. In the process of processing, it is often necessary to cut steel. In the process of cutting with a cutting machine, debris is often generated. If these debris enters the eyes of the processing personnel, it will harm the workers. Therefore, it is often mandatory to wear protective goggles when cutting. [0003] The existing protective goggles are engraved by an engraving machine to engrave the frame during production. During the engraving process, the plate needs to be fixed by a clamp before subsequent processing. However, the spectacle frame made of natural materials will be stuck on its surface if it is clamped for a long time. Leaving pinch marks, these pinch marks will d...
