Abstract
The invention relates to a method for producing a level bubble shell, and is characterized in that a level bubble core sleeve is adopted, at least two convex rings are produced on the surface of the level bubble core sleeve in advance, and are distributed on the left side and the right side of the surface of the level bubble core sleeve, then the level bubble core sleeve is injection-molded with transparent plastic concentrically, and embedded and fixed in a plastic level bubble blank, the sleeve body part of the level bubble core sleeve in the level bubble blank is turned, the convex ring parts are embedded into the level bubble blank to be used as scales, and thus the level bubble core sleeve is produced. The method has the advantages of simple and reasonable technology, easy production, high efficiency and high precision of obtained level bubble core sleeves.
Description
Technical field
The present invention relates to a kind of production method of level bubble shell.
Background technology
Air level is widely applied on the various measuring tools, as a detection level whether element, has a lot of scientific and technical personnel that air level has been done technological improvement for this reason.Traditional level bubble shell is to produce like this, earlier transparent plastic such as organic glass are injection molded into the bubble blank, see Fig. 1, go out the annular groove of many indents again in the cavity surface turning of bubble blank, annular groove is distributed in position, the left and right sides, see Fig. 2, then steel wire is embedded in and does in the annular groove as groove, made level bubble shell, its defective is, the technology more complicated, difficulty of processing is big, inefficiency, and low precision, directly influence the precision of measuring tool, particularly bubble blank cavity waist hole surface is subjected to the influence of annular groove, can't form the surface of smooth transition, and the drift that will certainly influence bubble is moved, thereby the reduction certainty of measurement, so need do further improvement design.
Summary of the invention
Technical problem to be solved by this invention provides the production method of a kind of technology advantages of simple, easily making, efficient height, level bubble shell that precision is good.
The technical scheme that the present invention solve the technical problem employing is: a kind of production method of level bubble shell, it is characterized in that adopting the bubble core retainer plate, and bubble core retainer plate surface is shaped on the above bulge loop of twice at least in advance, bulge loop is distributed on the position, the left and right sides on bubble core retainer plate surface, then, with the concentric injection mo(u)lding of bubble core retainer plate and transparent plastic, the bubble core retainer plate is mounted in the bubble blank of plastics, the cover body portion of bubble core retainer plate in the bubble blank is fallen in reface, bulge loop partly is embedded in the bubble blank becomes groove, has made level bubble shell.
As improvement, the cover body portion of described bubble core retainer plate is fallen simultaneously by turning, bubble blank cavity is lathed smooth waist internal surface of hole continuously, cavity and bulge loop are partly combined, make the waist internal surface of hole present smooth transition, be more conducive to steadily floating of bubble, avoid great-jump-forward to move, thereby improve the precision of measuring.
Improve, described bubble core retainer plate adopts aluminum, copper product or the color plastics different with transparent plastic again, be convenient to will be softer in turning process the cover body portion remove, and, aluminium or copper or plastics are not easy to send out rust in liquid, and more attractive in appearance, indicating effect is good.And the bubble core retainer plate can become dark colour with oxidation on metal surface, both has been convenient to indication, is not easy oxidized damage again.
At last, described bulge loop number is 4,6 or 8, is distributed in symmetrically on the position, the left and right sides on bubble core retainer plate surface, is convenient to the user more and carries out rough estimate according to the position of bubble, and is easy to use.
Compared with prior art, the invention has the advantages that: adopt bubble core retainer plate and the concentric injection molding process of transparent plastic, be more prone to make, the efficient height, and, bulge loop is to be embedded in one heart in the bubble blank, the concentricity precision height, and make the waist internal surface of hole present smooth transition, be more conducive to steadily floating of bubble, also help improving the precision of measurement, particularly the bulge loop number makes 4 easily, article 6 or 8,, be distributed in the position, the left and right sides on bubble core retainer plate surface symmetrically, make things convenient for the user to carry out rough estimate according to the position of bubble, adjust the measuring position, manufacturing approach craft is better, is fit to large-scale processing production.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Illustrate as Fig. 3-5, a kind of production method of level bubble shell, the crucial part of this invention is to adopt unique bubble core retainer plate 1, bubble core retainer plate 1 adopts aluminium or copper product, also can adopt plastics, when adopting plastics, can be different colours with the transparent plastic of doing the bubble blank preferably, it be more eye-catching outstanding to be convenient to groove.Bubble core retainer plate 1 utilizes Mould Machining to produce and obtains, in manufacture process, make the surface of bubble core retainer plate 1 be shaped on the bulge loop more than the twice 11 at least in advance, present embodiment is 6 road bulge loops 11, bulge loop 11 is distributed on the position, the left and right sides on bubble core retainer plate 1 surface, each end has 3 bulge loops, bubble core retainer plate 1 is oxidized to aterrimus, then, with the concentric injection mo(u)lding of bubble core retainer plate 1 and transparent plastic, bubble core retainer plate 1 is mounted in 2 li of the bubble blanks of plastics, in injection mo(u)lding, bubble core retainer plate 1 side molds larger-diameter perforate.The cover body portion 12 of bubble core retainer plate in the bubble blank is fallen in reface, simultaneously, bubble blank 2 cavities are lathed smooth waist internal surface of hole 21 continuously, make the waist internal surface of hole present smooth transition, like this bulge loop partly is embedded in the bubble blank 2, becomes groove 22, just made level bubble shell, further processing just is easy to make air level again.
Claims (4)
1. the production method of a level bubble shell, it is characterized in that adopting the bubble core retainer plate, and bubble core retainer plate surface is shaped on the above bulge loop of twice at least in advance, bulge loop is distributed on the position, the left and right sides on bubble core retainer plate surface, then, with the concentric injection mo(u)lding of bubble core retainer plate and transparent plastic, the bubble core retainer plate is mounted in the bubble blank of plastics, the cover body portion of bubble core retainer plate in the bubble blank is fallen in reface, make bubble blank cavity be lathed smooth waist internal surface of hole continuously, bulge loop partly is embedded in the bubble blank becomes groove, has made level bubble shell.
