Abstract

The invention discloses a turntable inner hole turning clamp, which relates to the technical field of mechanical processing tooling. It includes a clamp body, including a connecting plate and a positioning shaft. The positioning shaft is covered with an elastic chuck, and the elastic chuck is composed of a connecting seat and an elastic opening part; The outer sleeve of the elastic chuck is equipped with a positioning sleeve. The positioning sleeve has a fixed seat connected to the connecting seat. The connecting seat and the fixed seat are connected and fixed with the connecting plate by bolts; It includes a pressing plate and a sleeve inserted between the positioning sleeve and the elastic collet. The inner diameter of the sleeve gradually decreases from the insertion end toward the pressing plate; the positioning sleeve is provided with a locking bolt for locking the pressing sleeve. The invention solves the problem of low clamping reliability of the turntable inner hole car jig of the existing objective lens microscope.

Description

technical field [0001] The invention relates to the technical field of machining tooling, in particular to a turntable inner hole turning fixture. 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 order to limit the ...
