Abstract

The invention discloses a method for turning the inner hole of a turntable, which relates to the technical field of mechanical processing. The steps of the method are as follows: install the turning fixture of the inner hole of the turntable on the central taper hole of the lathe, loosen the locking bolt, and take out the pressure sleeve; Put the turntable into the elastic collet, make the outer spherical surface of the turntable contact with the positioning shaft, and level the outer end surface of the turntable; insert the sleeve of the pressure sleeve between the elastic collet and the positioning sleeve, and push the pressure sleeve inward , until the pressure plate abuts against the outer end surface of the turntable, and then tighten the locking bolts; turn the inner hole of the turntable, after processing, loosen the locking bolts, take out the pressure sleeve, and remove the turntable. The invention solves the problem of low turning quality of the inner hole of the existing turntable.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a turning method for an inner hole of a turntable. Background technique [0002] The objective lens converter is an important component of the mechanical device serving the microscope optical system. It is installed at the lower end of the lens barrel, including the fixed plate, the turntable and the positioning mechanism, etc. The fixed plate is fixed on the positioning mechanism, and the turntable rotates freely around the fixed plate. There are two to six holes on the top for installing the objective lens. Rotating the turntable can make the objective lenses of different multiples rotate to the optical axis of the microscope in turn to ensure that the light rays of the objective lens and the eyepiece are aligned. In order to make the turntable rotate more smoothly, balls and washers are arranged between the fixed plate and the inner wall of the turntable. In orde...
