Summary of the invention
First purpose of the present utility model provides the processing technology that the timer that adopts bar to process balance staff is used the shaping escapement, the balance staff form stable that bar is processed into, the precision of processing is high, not yielding in thermal treatment, guarantee the precision size of the shaping pendulum nail on the balance staff, thereby can guarantee the timekeeping performance of timer;
Second purpose of the present utility model provides the timer shaping escapement that adopts above-mentioned processing technology to be processed into, and this shaping escapement intensity is high, and the precision size also is guaranteed.
For achieving the above object, the utility model has adopted following technical scheme: a kind of timer shaping escapement, comprise bar-shaped axostylus axostyle, be wholely set on described bar-shaped axostylus axostyle side surface and be the shaping pendulum nail processing technology part of non-closed circular, be wholely set on described bar-shaped axostylus axostyle both ends of the surface and the bar-shaped axle falcon thinner than this bar-shaped axostylus axostyle, be arranged on the pendulum on the described bar-shaped axostylus axostyle side surface, all convex to form the pendulum nail that is shaped on two broken surfaces of described shaping pendulum nail processing technology part based on non-closed circular formation, described shaping pendulum is followed closely and is exceeded the position of described bar-shaped axostylus axostyle between two broken surfaces of described shaping pendulum nail processing technology part.
During implementation, be provided with mounting groove on the described bar-shaped axostylus axostyle side surface, described pendulum is fixedly connected in the described mounting groove.
A kind of timer processing technology of shaping escapement may further comprise the steps:
(1) chooses bar, described bar is processed to form shaping balance staff shaft blank, this shaping balance staff shaft blank has bar-shaped axostylus axostyle, be wholely set on the middle part of described bar-shaped axostylus axostyle side surface and be closed circular shaping pendulum nail processing technology part, be wholely set on the middle part of described bar-shaped axostylus axostyle both ends of the surface and the bar-shaped axle falcon thinner than this bar-shaped axostylus axostyle, also be provided with mounting groove on the described bar-shaped axostylus axostyle side surface;
(2) axial direction along shaft blank cuts described shaping balance staff shaft blank, described shaping pendulum nail processing technology part is opened in cut-out, and the shaping pendulum that all forms projection on two surfaces that disconnect is followed closely, cut away simultaneously the described bar-shaped axostylus axostyle of part between two surfaces of described shaping pendulum nail processing technology disconnection partly, so that the two lip-deep described shaping pendulum nails that disconnect all exceed the position of described bar-shaped axostylus axostyle between two surfaces of this disconnection, processing has obtained the shaping balance staff like this;
(3) the shaping balance staff that step (2) is obtained is heat-treated, electroplating surface is processed;
(4) pendulum is fixedly connected in the mounting groove of the shaping balance staff after step (3) is processed, namely obtains the escapement that is shaped.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages: the balance staff in the shaping escapement processes through bar, with respect to sheet moulding, bar-shaped balance staff form is more stable, intensity is higher, and the precision size of processing is also higher, and is not yielding in thermal treatment, thereby guaranteed the precision size of the shaping pendulum nail on the balance staff, can guarantee like this timekeeping performance of timer.

Embodiment
Further set forth the utility model below in conjunction with accompanying drawing.
The timer processing technology of shaping escapement referring to Fig. 1-4, may further comprise the steps:
(1) chooses bar, for example choose the carbon steel bar of Ф 4.2, bar is processed to form shaping balance staff shaft blank 1 ', as shown in Figure 4, the operation of this processing can be carried out at automatic lathe, shaping balance staff shaft blank 1 ' has bar-shaped axostylus axostyle 11, be wholely set on the middle part of bar-shaped axostylus axostyle 11 side surfaces and be closed circular shaping pendulum nail processing technology part 13, be wholely set on the middle part of bar-shaped axostylus axostyle 11 both ends of the surface and the bar-shaped axle falcon 12 thinner than this bar-shaped axostylus axostyle 11, also be provided with mounting groove 15 on bar-shaped axostylus axostyle 11 side surfaces;
(2) along the axial direction shaping by stock removal balance staff shaft blank 1 ' of shaft blank 1 ', before cutting, at first to make form cutter, then it is firm shaping balance staff shaft blank 1 ' to be put between hobbing machine two thimbles clamping, with form cutter shaft blank 1 ' is axially formed Milling Process along it, cut-out is split into shape pendulum nail processing technology part 13, destroy the closed circular of the pendulum nail processing technology part 13 that is shaped, and the shaping pendulum that all forms projection on two surfaces that disconnect follows closely 14, as shown in Figure 3, cut away simultaneously at the bar-shaped axostylus axostyle 11 of part that is shaped between two surfaces of putting the disconnection of following closely processing technology part 13, so that the two lip-deep shaping pendulum nails 14 that disconnect all exceed the position of bar-shaped axostylus axostyle 11 between two surfaces of this disconnection, as shown in Figure 2, processing has obtained shaping balance staff 1 like this;
(3) the shaping balance staff 1 that step (2) is obtained is heat-treated, electroplating surface is processed, because shaping balance staff 1 processes through bar, with respect to sheet moulding, form is more stable, and intensity is higher, and the precision size of processing is also higher, not yielding in thermal treatment, thereby guaranteed the precision size of the shaping pendulum nail 14 on the balance staff 1, can guarantee like this timekeeping performance of timer, the escapement boss on the pendulum of the shaping on the balance staff 1 here nail 14 balancing arbors that are equivalent to mention in " background technology ";
(4) pendulum 2 is fixed in the mounting groove 15 of the shaping balance staff 1 after step (3) is processed by riveted joint, namely obtains the escapement that is shaped, as illustrated in fig. 1 and 2, the principle of work of shaping escapement in timer participated in the patent documentation of mentioning in " background technology ".
The timer shaping escapement that makes by above-mentioned processing technology, as illustrated in fig. 1 and 2, comprise bar-shaped axostylus axostyle 11, be wholely set on bar-shaped axostylus axostyle 11 side surfaces and be the shaping pendulum nail processing technology part 13 of non-closed circular, be wholely set on bar-shaped axostylus axostyle 11 both ends of the surface and the bar-shaped axle falcon 12 thinner than this bar-shaped axostylus axostyle 11, be arranged on the mounting groove on bar-shaped axostylus axostyle 11 side surfaces, be fixedly connected on the pendulum 2 in this mounting groove, the pendulum that is shaped is followed closely on two broken surfaces of processing technology part 13 based on non-closed circular formation and is all convexed to form the pendulum nail 14 that is shaped, the pendulum nail 14 that is shaped exceeds the position of bar-shaped axostylus axostyle 11 between two broken surfaces of pendulum nail processing technology part 13 that are shaped, and the pendulum nail 14 that is shaped like this can work to the ratchet in the timer escapement effect that stops and discharge.The shaping escapement adopts bar-shaped balance staff 1, and intensity is higher, and form is more stable, processes not yieldingly, and the precision size also is guaranteed, thereby improves the timekeeping performance of timer.
