Abstract

The present invention relates to a coil spring for a timing instrument. A coil spring of clock and meters is made into a component, and no molecular interruption exists between the coil spring and an elastic clamping head of the coil spring.

Description

The disc spring of time keeping instrument

Technical field:

Of the present invention to liking the clock and watch disc spring of using when surveying.

Background technology:

Disc spring commonly used in the clock and watch is to be assembled by several parts, and the necessary high precision manufacturing of these parts is assembled into a subassembly then.Because make complexity, thereby the cost height, assemble also very complicated.

Summary of the invention:

The objective of the invention is to provide a kind of disc spring, and its production cost is low as far as possible, and if possible, failsafe during use.

According to disc spring of the present invention, it is characterized in that it makes parts, and do not have molecule with its collet and be interrupted.

Parts of fine quality, complete equipilibrium have been produced with disc spring of the present invention.It makes parts and this fact of free of discontinuities has been avoided the intrinsic shortcoming of conventional production methods, the low problem of precision when the assembling of internal stress and component part thereof is especially arranged in the material.In addition, according to disc spring of the present invention, its production cost is more much lower than prior art spring.

More favourable part is, can produce with prior art according to disc spring of the present invention, for example, by little method of molding production, suppress with the mould that the exposure to ultraviosensitive resin is made, adopt or carry out electro-deposition, with the material spraying plating or use traditional cutting processing without mould, particularly laser, Wire EDM or die electrodischarge machining are with punching press or use the high pressure liquid jet cuts sheet material.

Disc spring can have a stub, also is made of one and does not have molecule with its terminal curve and be interrupted.Stub can be made cylindrical, and its height is identical with disc spring reed height.Stub can be made the part wideer than reed, and certain elasticity is arranged, and can rely on friction to inject in the jack, and this broad part can be made the annular rod member of two flexibilities.

Stub can rely on friction to insert in the hole of bearing, and by its loose its elastic stress and locking in hole vertical with bearing hole or that intersect vertically.

In disc spring according to the present invention, collet has a seam and two openings, and the latter can make parts reach static equilibrium and available assembly tool clamping.

Collet also can have the reference breach on its edge.

On the end that is made of one with terminal curve one or several otch can be arranged, this otch can with the screw-threaded engagement of screw, screw is fixed in the bearing vertically, embeds supporting lining in the bearing as the fixed location of disc spring.

At last, disc spring can be used little molding technology, with the mould compacting that the exposure of ultraviolet-sensitive resin is made, with or without the electro-deposition of mould processing, spray or use traditional patterning method with material, particularly use laser, Wire EDM or groove electrodischarge machining, with punching press or with method manufacturings such as high pressure liquid jet cuts sheet material.

Specific embodiment:

Disc spring 10 shown in Figure 1 is formed by reed 11, the flexible chuck 12 in its center, and its external end has terminal curve 13.

Parts shown in Figure 1 comprise its

ingredient

11,12,13, are made of one, and its molecular structure is uninterrupted.

It can be made of following technology:

Little molding technology comprises Applied Electrochemistry technology plated metal in mould.Metalling on matrix.

Use the classic method cuts sheet material.

Use the high pressure liquid jet cuts sheet material.

Process above-mentioned is used to disc spring and the variant in Fig. 2-8 in the construction drawing 1, obtains good result.

They can be used for making according to disc spring of the present invention, and this disc spring is made of one and does not have molecule and be interrupted.Little molding production technology has special excellent effect.

As shown in Figure 1, collet 12 is made big annulus and a seam 14 is arranged, and makes it can compel to be incorporated on the bearing pin and can not split or swell when assembling.

Disc spring 10 shown in the variant shown in Figure 2 has its collet 12 and terminal curve 13, and a seam 14 is arranged on the collet 12.

The terminal of curve 13 has a circular stub 15 endways, it and disc spring and collet thereof are made of one and do not have molecule and be interrupted, obviously, the shape of stub 15 is not limited to circle, stub can be made the shape of any requirement, for example makes the cylinder of the trough of belt as traditional clock and watch, or makes any suitable geometric configuration, can there be a hole in the central authorities of terminal circular protrusion, are beneficial to the fixing of it.

Fig. 3 illustrates the enlarged perspective of the stub 15 among Fig. 2.

Fig. 4 illustrates a kind of variant of stub 15, and it has two certain flexible

annular rod member

16,17 is arranged.Stub among Fig. 4 is because flexible, and can rely on rubs injects in the hole 18 of removable stub bearing 19 or clock and watch base plate 19.One upright opening 20 is arranged on the part 19, and the stub 15 of method for making shown in Figure 4 is locked in the hole 20 owing to

rod member

16,17 is returned to virgin state in this hole 20.

Shown in Figure 6 have on seam 14 the collet 12 two

openings

21 and 22 are arranged, at first can be used to provide by reed 11, collet 12, and according to circumstances also have the static equilibrium of the parts that terminal curve 13 constitutes, next helps to clamp these parts with instrument.

In variant shown in Figure 7, all otch are used for distinguishing the type of disc spring.Three otch 23 have been shown on Fig. 7, but the shape of otch and quantity can be selected as required.Method for making shown in Figure 8 is a disc spring 30, and the spring of it and aforementioned method for making is similar, and its collet 12 is arranged, seam 14 and terminal curve 13 thereof.

At this moment, stub is made with the no molecules of terminal curve 13 are interrupted and is widened terminal 31.On terminal 31 otch 32 is arranged, with the screw-threaded engagement on the screw 33, two of screw 33 usefulness are arranged in the pin 34 in the hole 35 of bearing 36 and fix.

Are smooth flat 37 with tooth 32 opposite parts on terminal 31, therefore, when screw 33 rotates end 31 just can surface 38 at bearing 36 on slip.The rotation of screw 33 can be used for adjusting terminal 31 position, so that change the effective length of terminal curve 13.

Supporting lining 39 by synthetic material or metal manufacturing is used for laterally keeping the disc spring fixed position by rubbing.

This method for making is in top explanation, and said method advantageous particularly part is available little molding methods with the alloy manufacturing of nonmagnetic rustless metal.
