具体实施方式: detailed description:

[0015] 实施例1 : [0015] Example 1:

[0016] 下面结合附图和具体实施方式对本实用新型作进一步详细的说明。 [0016] Hereinafter, the present invention will be further described in detail in conjunction with accompanying drawings and specific embodiments.

[0017] 以制作一个检测M14沉头螺栓的检具为例,在本实施例中,量具是用一块耐磨的高速钢材料的底板制作而成,用高精度的慢走丝机床在底板的边缘由外向内加工出通端检测槽A和止端检测槽B (如图2所示)。 [0017] In making a countersunk bolt M14 detect gage, for example, in the present embodiment, a high speed steel plate with a gage is made of wear-resistant, high-precision EDM machine with the base plate processed through from outside to inside edge of the detector of the detector channel A and channel stop B (FIG. 2).

[0018] 由于M14沉头螺栓头部外圆大端直径约为31mm,螺栓杆径为14. 5mm,所以本检具的通端检测槽A和止端检测槽B的大台阶槽的宽度Lai = Lbi,等于31mm;中间台阶槽的宽度La2 = Lb2,等于20. 57mm ;小台阶槽的宽度La3 = Lb3,等于14. 5mm。 [0018] Because M14 countersunk screw head large end outer diameter of about 31mm, diameter of the bolt shank 14. 5mm, the width of the groove of the present large step gage of the detector through the slot A and slot B of the end-stop detection Lai = Lbi, equal to 31mm; width of the intermediate stepped groove La2 = Lb2, equal to 20. 57mm; width of the small stepped groove La3 = Lb3, equal to 14. 5mm.

[0019] 通端检测槽A的大台阶槽高度Pai等于3. 132mm;止端检测槽B的大台阶槽高度IV 等于3. 06mm ;A、B两槽中间台阶槽的高度等于3mm,小台阶槽的高度等于15mm。 [0019] A groove of the detector through the large step height of Pai is equal to the groove 3. 132mm; end stop detecting step for slot B Large IV equal to the height of the groove 3. 06mm; A, two grooves intermediate step height B is equal to the groove 3mm, a small step the height of the groove is equal to 15mm.

[0020] 另外,从图1可以看出,用高度衬套和卡板进行测量时,由于铆钉或螺栓沉头部分频繁地与工作孔口接触,易造成孔口磨损,孔口处产生R,导致原有量具报废。 [0020] Further, it can be seen from FIG. 1, when measured with a high degree of liner board and card, since the countersunk head rivets or bolts frequent contact with the working portion aperture, orifice easily lead to wear, at the orifice to produce R, resulting in the potential measuring scrapped. 而本实用新型所述的新型量具严格要求大台阶与中台阶转角处加工时不允许有R,以确保测量结果的正确性。 And according to the present invention novel measuring step with the stringent requirements of a large step does not allow the corner R machining, to ensure the accuracy of measurement results.

[0021] 在使用本实用新型所述的新型量具进行通端测量时,先用沉头螺栓大端面与量具的M面接触,(这样就避免了螺栓沉头部分与量具的转角处先接触,而导致转角处的尖角被磨损产生R,造成量具报废)再移动螺栓通过整个通端检测槽,看零件是否能够通过;同理可进行止端测量。 [0021] When using the present invention, the novel measuring is performed through the end of the measurement, the first contacting surface M countersunk head bolt end face of the large gage, (thus avoiding the corner measuring bolt with countersunk head portion of the first contacts, resulting sharp corner is worn to produce R, measuring resulting scrap) then move through the bolt through the entire channel of the detector to see if the part through; the same can be end-stop measurement.
