Abstract
An axle needle of a magnetic compass comprises an axle needle body and is characterized in that the axle needle body comprises an axle rod, and a ball pen point arranged at the top of the axle rod and used as an axle needle tip. The invention further provides application of the ball pen point in the manufacture of the axle needle of the magnetic compass. The axle needle body comprises the axle rod and the axle needle tip arranged at the top of the axle rod, and the ball pen point is arranged at the top of the axle rod and used as the axle needle tip. As the axle needle tip of the magnetic compass is made by the ball pen point, the raw material is economical, substantial, and convenient to select. When the axle need is made, the technology is simple, and the ball pen point only needs to be welded at the top of the axle rod. The ball head is positioned at the pen tip part of the ball pen point. The ball head is smooth, highly neat, spherical, wear-resistant and highly centralized. Through the adoption of the ball pen point to be used as the axle needle tip, the friction between the axle needle tip and an axle cap on the dial of the magnetic compass is very small, and terrestrial magnetism force is hardly affected by the compass dial.
Description
Technical field
The present invention relates to a kind of axonometer of magnetic compass and the application that ball nib is made magnetic compass axonometer.
Background technology
Magnetic compass claims again " magnetic compass ", is a kind of instrument of measuring directional reference, for determining course and observation thing mark orientation.It is to utilize needle to be subject to the stable instrument that refers to the indication geographic direction that northern characteristic is made of ground magnetic action.The compass of magnetic compass comprises index dial, floating chamber, magnet steel and axle cap, compass is arranged on axonometer, and the needle on compass (or magnet steel) is subject to ground magnetic action direction indication by needle, the axonometer head (or claiming most advanced and sophisticated) that axle cap is located at axonometer above, swings compass on axonometer head.In use procedure, be repeatedly to swing by telluric magnetic force effect, therefore need anti-wear performance high with the supporting swing of axonometer formation, again because telluric magnetic force is very little, thereby be easily subject to External force interference to affect precision, therefore need again to avoid or reduce the interference of the friction force between axonometer head and axle cap.At present main adopt be iraurite as axonometer head, axle cap adopts jewel to make magnetic compass, but iridium (y ī) gold is rare precious metal, is the alloy of platinum and iridium, rare degree is on platinum, cost of manufacture rises.Secondly, in the manufacturing process of iraurite as axonometer head, one granule iraurite need to be inlayed to (as welding) at axostylus axostyle top, then by manually polishing, polish axonometer head most advanced and sophisticated, but manual polishing easily causes the waste of iraurite, easily cause most advanced and sophisticated rough jagged, easily cause most advanced and sophisticated sealing eccentric (centrad), easily cause in processing bruting process, iraurite to be beaten many unfavorable factors that affects magnetic compass precision and wearing quality such as to fly.
Summary of the invention
In view of the technical matters existing in background technology, technical matters solved by the invention aims to provide a kind of axonometer of magnetic compass and the application that ball nib is made magnetic compass axonometer.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of axonometer of magnetic compass, include axonometer body, and it is characterized in that: described axonometer body comprises axostylus axostyle and is arranged on axostylus axostyle top as the ball nib of axonometer head.
Ball nib is made the application of magnetic compass axonometer, and axonometer body comprises axostylus axostyle and is arranged on the axonometer head at axostylus axostyle top, ball nib is arranged on to axostylus axostyle top as axonometer head.
Ball nib is welded on axostylus axostyle.
Beneficial effect of the present invention is to adopt ball nib to make its raw material economics material benefit of axonometer head of magnetic compass, the convenience of selecting materials; While making axonometer, technique simply only needs ball nib to be welded on axostylus axostyle top; The nib place of ball nib is ball bulb, and ball bulb is smooth, highly polished, be spheroidal, wear-resisting and centrad is very high; Adopt ball nib very little as the friction force between the axle cap on the compass of axonometer head and magnetic compass, affect hardly the telluric magnetic force that compass is subject to.Therefore the present invention compared with prior art has substantive distinguishing features and progress.
Accompanying drawing explanation
Details and the principle of work of embodiments of the present invention and embodiment are described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention partly assembles exploded perspective view.
Embodiment
Referring to accompanying drawing, a kind of axonometer of magnetic compass in this embodiment, includes axonometer body, and described axonometer body comprises axostylus axostyle 21 and is arranged on axostylus axostyle top as the ball nib of axonometer head.Ball nib is the nib of ball pen, water-color paintbrush, gel ink pen etc., and it comprises ball (spherical, or claim ball) and the ball seat composition at nib place, ball is put on ball seat, and ball seat closes up, and encases ball, allow ball be unlikely to drop out and ball can roll on ball seat, complete nib.The compass of magnetic compass is arranged on axonometer, on compass, be also provided with needle (or magnet steel), by needle, be subject to telluric magnetic force effect direction indication, the compass of magnetic compass is also provided with axle cap and (generally adopts diamond material, as ruby), axle cap is located on the axonometer head of axonometer, and compass is swung on axonometer head.Therefore when making axonometer, need to consider the anti-wear performance of axonometer head, and the size of the friction force between axonometer head and axle cap (being easily subject to External force interference because telluric magnetic force is very little), and adopt ball nib to make its raw material economics material benefit of axonometer head of magnetic compass, select materials conveniently; While making axonometer, technique simply only needs ball nib to be welded on axostylus axostyle top; The nib place of ball nib is ball bulb, and ball bulb is smooth, highly polished, be spheroidal, wear-resisting and centrad is very high, the high degree of accuracy that can ensure when compass rotates of centrad; Adopt ball nib very little as the friction force between the axle cap on the compass of axonometer head and magnetic compass, affect hardly the telluric magnetic force that compass is subject to.Axonometer body bottom is arranged on axonometer seat 20, then after aiming at by axonometer seat, be arranged on axonometer mount pad 8, being different from prior art axonometer body is directly integrated on axonometer mount pad, because there will be and depart from center when axonometer mount pad is installed, so axonometer also will depart from center and affect its precision; Axonometer body in the application be partial installation setting therefore can guarantee that its centrad is high, guarantee precision.
Ball nib is made the application of magnetic compass axonometer, and axonometer body comprises axostylus axostyle and is arranged on the axonometer head at axostylus axostyle top, ball nib is arranged on to axostylus axostyle top as axonometer head.Ball nib is arranged on axostylus axostyle in the mode of welding, and manufacture craft is simple and convenient.Adopt ball nib to make its raw material economics material benefit of axonometer head of magnetic compass, select materials conveniently; While making axonometer, technique simply only needs ball nib to be welded on axostylus axostyle top; The nib place of ball nib is ball bulb, and ball bulb is smooth, highly polished, be spheroidal, wear-resisting and centrad is very high, the high degree of accuracy that can ensure when compass rotates of centrad; Adopt ball nib very little as the friction force between the axle cap on the compass of axonometer head and magnetic compass, affect hardly the telluric magnetic force that compass is subject to.
