A fast loading and unloading device for screws when changing blades of an internal circular slicer

Abstract

The invention provides a device for quickly assembling and disassembling screws during inside diameter slicer cutter blade replacing. The device comprises a rocking handle, an inner fixing disc, an outer fixing disc, a driving shaft, a plurality of driven shafts, a driving gear, a plurality of driven gears, a moving disc and a straight internal hexagonal wrench; the driving shaft drives the drivenshafts to rotate through gear transmission at first and finally drives the straight internal hexagonal wrench to rotate, meanwhile, the driving shaft drives the moving disc to move inwards through thread transmission, then, pushes the driven shafts to slide inwards in the axial direction and finally pushes the straight internal hexagonal wrench to move inwards, or the screws which are unscrewed outwards push the straight internal hexagonal wrench to move outwards, accordingly the driven shafts are pushed to slide outwards axially, and screw assembling and disassembling are achieved. The device can replace partial manpower, the torque borne by the screws in the tightening process is uniform, inside diameter slicing cutter blade distortion deformation is avoided, the cutter blade fasteningquality is improved, the assembling and disassembling time is shortened, and the efficiency of labor is improved.

Description

technical field [0001] The invention relates to the technical field of precision cutting, in particular to a quick loading and unloading device for screws used for changing blades of an internal circle slicer. Background technique [0002] In engineering practice and scientific research, it is often necessary to perform precision or ultra-precision machining on hard and brittle materials such as ceramics, semiconductors, and hard alloys, as well as various difficult-to-machine metal materials. An important link to realize precision or ultra-precision machining. [0003] The internal circle slicer is often used to cut and produce flakes of hard and brittle materials such as magnetic materials, semiconductor materials, gemstones, ceramics and various glasses. [0004] Before the inner circle slicer works, first align the inner circle cutting blade with the threaded hole and place it between the concave and convex rings, then use the inner hexagonal wrench to gradually tighten...

AI Technical Summary

Problems solved by technology

[0005] When disassembling and installing the blade, the operator needs to use the L-shaped hexagonal wrench to frequently screw the inner hexagonal screws. A total of 20 inner hexagonal screws need to be tightened, which is a great test for the physical strength of the operator, and the operator needs to be careful about each inner hexagonal screw. The torque applied by the hexagonal screws is almost the same, otherwise the different torques will cause uneven force on the blade, and the blade is easy to distort and deform, which not only affects the accuracy of the workpiece, but also may cause the blade to crack during processing and damage the blade or workpiece
