Lens blind hole perforating machine

Abstract

The invention discloses a lens perforating machine, which solves the problems that the existing lens perforating machine has low perforating precision and difficulty in controlling perforating depth and holding lens. The structure is as follows: a lens blind hole perforating machine comprises a base and a motor arranged on the base, a power output shaft of the motor is connected with a drill bit. The machine is characterized in that the base is thereon provided with a workbench below the drill bit, a lifting mechanism is arranged between the workbench and the base, which can be operated to ensure the lifting of the workbench on the base; the workbench is thereon provided with a clamp for holding lens, and a clamping part of the clamp for clamping the lens can rotate.

Description

technical field [0001] The invention relates to a hole punching machine, in particular to a lens blind hole punching machine for processing blind holes on glasses lenses. Background technique [0002] During the processing of glasses, it is sometimes necessary to punch holes on the lens. In order to pursue fashion or improve the grade of glasses, it is sometimes necessary to inlay some decorations on the lens, and these decorations need to be fixed on the lens. The blind hole of the lens so that the decoration is firmly fixed on the lens. Chinese utility model patent: 200620105153.3 discloses a lens punching machine. The structure of the lens blind hole punching machine includes a base, a motor and a fixture arranged on the base, and a drill bit is fixedly connected to the lower end of the power output shaft of the motor. Also be provided with pressing bar on motor. By operating the pressure rod, the vertical distance between the drill bit and the base can be changed, so ...

AI Technical Summary

Problems solved by technology

The pressure rod is connected with the whole motor or the rotating parts. When the pressure rod is connected with the rotating parts, the axial position of the drill bit will change under the action of the pressure rod. There must be a gap between the drill bit and the power output shaft of the motor. It has an axial movable connection structure, which will affect the radial stability of the drill bit, which will affect the processing accuracy of the lens hole, and the mouth of the hole is prone to collapse; when the pressure rod is connected with the entire motor, the motor It must be a movable connection with the bracket set on the base. On the one hand, this will make the connection structure between the pressure rod and the motor complicated, and on the other hand, the radial stability of the drill bit cannot be guaranteed.

When the pressure rod controls the processing depth of the lens hole, it is convenient and quick to control the perforation processing, but for some blind hole processing with processing depth requirements, quantitative control cannot be performed.

[0003] In addition, after clamping the lens, the clamp on this lens punching machine can only translate in the horizontal direction, and the lens is normally curved. If you want to ensure that the lens hole is perpendicular to the lens surface, to fully The thickness of the lens is used to facilitate the assembly of decorations, and the requirements for clamping the lens are relatively high, which is troublesome for the clamping operation of the lens, and when processing different holes on the lens, the lens needs to be clamped again
