A telescope lens barrel milling processing fixture

Abstract

A milling clamp for telescope lens barrels comprises a clamp body, a positioning device and a clamping device. The clamp body is formed by a bottom plate, a left side plate, a right side plate, a cover plate, a front side top plate and a rear side top plate in an enclosed mode. The center of the left side plate and the center of the right side plate are each provided with a hole. The positioning device comprises large end positioning device bodies and small end positioning device bodies which are arranged on the two telescope lens barrels symmetrically. A first part of the clamping device comprises inverted-Y-shaped supports symmetrically arranged in the middles of the front side and the rear side of the bottom plate, long threaded rods located at the inner sides of the inverted-Y-shaped supports and pressing blocks which are pressed on the inverted-Y-shaped supports, and the inner end and the outer end of each pressing block are installed on the corresponding long threaded rods in a sleeving mode. A second part of the clamping device comprises a main rod, an adjusting threaded rod, middle pressing blocks and a main adjusting nut, wherein the main rod is vertically installed in the center of the bottom plate, and the top of the main rod is provided with an inner threaded hole; the adjusting threaded rod is installed in the inner threaded hole in the top end of the main rod in a matched mode; the middle pressing blocks are sequentially installed on the adjusting threaded rod in a sleeving mode; the top end of the adjusting threaded rod is inserted in the cover plate. By means of the clamp, position control and accuracy control over outer machining surfaces of the telescope lens barrels can be achieved rapidly and accurately.

Description

technical field [0001] The invention relates to the technical field of milling fixtures for side parts of telescope lens barrels. Background technique [0002] Such as figure 1 As shown, the outer side of the telescope lens barrel is an irregular curved surface, and the hole C on the curved surface needs to be milled, but the traditional processing fixture can only clamp and process one part at a time, the work efficiency is low, and it cannot be automatically centered, clamped, and positioned. The operation is inconvenient, and the size of the processing position is difficult to guarantee. Contents of the invention [0003] The object of the present invention is to solve the problems of the prior art, and provide a telescope barrel milling fixture with reasonable structure, convenient operation, and fast and accurate control of the position and precision of the outer processing surface of the telescope barrel. [0004] The purpose of the present invention is achieved th...
