Description

Clamping tool for manual chamfering of fan-shaped metal thin ring

Technical Field

The utility model relates to a manual chamfer construction frock technical field of fan-shaped metal thin ring specifically is a clamping tools that is used for manual chamfer of fan-shaped metal thin ring.

Background

The method is characterized in that the method comprises the following steps that in the process of chamfering a light and thin small workpiece by a fitter, particularly for the machining operation of a thin oil scraping ring of a marine low-speed oil extraction machine, the following problems often exist in the fixation of the thin oil scraping ring: 1. if one hand is used for fixing the feeding piece, the other hand is used for holding the file to chamfer the feeding piece. Firstly, because the workpiece is light and thin and the fixation is not reliable, the force applied by the file on the workpiece can loosen the workpiece from the fixed hand, and the file can bruise the surface or edge which does not need to be chamfered; secondly, because the fixation is unreliable, the workpiece is deformed in the thickness direction by the force in the sharp edge blunting construction, so that the workpiece is uneven; 2. if the workpiece is clamped by the aid of a general auxiliary clamping tool, namely the bench vice, the bench vice is generally clamped at a place where the workpiece does not need to work, the surface needing to be constructed is exposed above the jaw or in the middle of the jaw, and after construction is finished, one surface is replaced to clamp the workpiece, and other elements are continuously constructed. Aiming at the fan-shaped metal thin ring, the construction content is to perform sharp edge blunting on the excircle of the fan-shaped thin ring, the fan-shaped thin ring is narrow in width and long in arc length, too many bench vices cannot be exposed during clamping, and the clamping is reliable. In the past, clamping of a fan-shaped metal thin ring workpiece is that a bench worker continuously changes a clamping position, one section is clamped and constructed, and the clamping is changed until the construction of the whole section of the thin ring workpiece is finished. The method has the advantages of less construction content, more clamping times and inconvenient whole construction process. To this end, we propose a clamping tool for manual chamfering of thin metal sector rings to solve the above-mentioned problems.
