Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] The invention provides a device capable of filing the cylindrical surface of a bar at low speed, such as Figure 1 to Figure 3 As shown, a box body 1 with an opening at the top is included, and a rotating shaft 2 with one end protruding outward is arranged horizontally in the box body 1. One end of the rotating shaft 2 located outside the box body 1 is connected with a handrail 3, and the handrail 3 is connected to the outer wall of the box body 1. The rotating shaft 2 between them is provided with a positioning mechanism, and one end of the rotating shaft 2 located in the box body 1 is coaxially connected with a four-jaw ferrule 4. In order to improve the filing efficiency of the bar 16, the contact between the bar 16 and the The action time of the device in the non-filing stage, by setting the lock 15 on the outside of the four-jaw f...

Abstract

The invention discloses a device capable of rasping a cylindrical surface of a bar at a low speed. The device comprises a box body with an opening in the top end; a rotating shaft with one end protruding outwards is arranged horizontally in the box body; one end, positioned outside the box body, of the rotating shaft is connected with a handrail; a positioning mechanism is arranged on the rotatingshaft between the handrail and the outer wall of the box body; one end, positioned in the box body, of the rotating shaft is coaxially connected with a four-jaw ferrule; an accommodating opening is formed in the side wall of the box body directly facing the four-jaw ferrule; a restraining structure is arranged in the accommodating opening; a pair of placement openings are correspondingly formed in the side walls of the box body on two sides of the rotating shaft; and a pair of raspers is jointly erected in the pair of placement openings. The device capable of rasping the cylindrical surface of the bar at the low speed greatly reduces the labor intensity, the damage index and the grinding uniformity of manual rasping, also improves the bar rasping efficiency and avoids the oxygen measurement result distortion.

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...
