Optical lens grinding machine

Abstract

The invention discloses an optical lens grinding machine. The optical lens grinding machine comprises a base and a bracket, wherein a groove is formed in the upper surface of the base; a shock absorber is arranged inside the groove; the shocker absorber is equipped with a workbench; a second threaded rod is arranged inside the workbench; the surface of the second threaded rod is rotatably connected with a clamp; the two sides of the clamp are equipped with lower transparent protective shells; the surface of the upper end of the right side of the workbench is equipped with a fan; the upper endof the fan is equipped with a threaded sleeve; and the surface of the upper end of the workbench is equipped with a bracket. When a user uses the optical lens grinding machine to grind an optical lens, the second threaded rod can be firstly rotated, so that a movable frame moves towards the middle; a workpiece is preliminarily clamped through an arc-shaped clamping hole; the user can regulate a fine tuning nut and then further clamps the lens for guaranteeing absolute clamping; and harm on a human body is caused if a great deal of dust generated by grinding is not treated in work.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to an optical lens grinding machine. Background technique [0002] Optical glass is mixed with oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasonic waves, and removed air bubbles; The temperature is lowered slowly over time to avoid internal stress in the glass block. The cooled glass blocks must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to form optical lens blanks. [0003] Existing lens grinding and manufacturing equipment can grind optical lenses according to different shapes, so as to make them meet the requirements of optical instruments. However, most ...
