A device that can file and grind the cylindrical surface of bar material at low speed

Abstract

The invention discloses a device capable of filing and grinding the cylindrical surface of rods at low speed, which comprises a box body with an open top, and a rotating shaft with one end protruding outward is horizontally arranged in the box body, and a handrail is connected to the end of the rotating shaft outside the box body. The rotating shaft between the armrest and the outer wall of the box is provided with a positioning mechanism. One end of the rotating shaft located in the box is coaxially connected with a four-jaw ferrule. A restraining structure is arranged in the opening, and a pair of openings are correspondingly opened on the side walls of the box on both sides of the rotating shaft, and a file is jointly erected in the pair of openings. The present invention is a low-speed filing device for bar cylindrical surface, which greatly improves the labor intensity, damage index and grinding uniformity of hand-held filing. The measurement results are distorted.

Description

technical field [0001] The invention belongs to the technical field of bar cold grinding devices, in particular to a device capable of filing and grinding bar cylindrical surfaces at low speed. Background technique [0002] Oxygen concentration in metals and alloys has a great influence on the physical and mechanical properties of materials, and must be strictly controlled during the refining process. The existence and determination of oxygen in materials is not only considered as a harmful impurity, but also has become a must-measure element for some materials in applications, or as a standard limited target. With the continuous development of detection technology, the main method for determining the concentration of oxygen in metals and alloys at this stage is to use pulse heating-infrared absorption heat conduction method to perform analysis. [0003] When measuring the oxygen concentration in metals and alloys, one or more block samples are usually cut from the raw mate...
