Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The Special caliper for detecting object gap fast as shown in Figure 1, comprises main card chi 1 and vice card chi 2.Shown in composition graphs 2, the head of main card chi 1 is provided with main card chi jaw 1a, middle part is provided with the main pin hole 1b installing and connect round pin 3, and afterbody is provided with to connect the circular arc master calibration plate 1c that round pin 3 center is the center of circle, master calibration plate 1c is circumferentially distributed with the scale mark with calibration value; Shown in composition graphs 3, the head of vice card chi 2 is provided with vice card chi jaw 2a, middle part is provided with the secondary pin hole 2b installing and connect round pin 3, afterbody is provided with to connect the secondary scaleplate 2c of circular arc that round pin 3 center is the center of circle, secondary scaleplate 2c is provided with the arrow 2d for reading corresponding scale mark on master calibration plate 1c.
The inner arc radius of master calibration plate 1c is identical with the outer arc radius of secondary scaleplate 2c and be A, main card chi jaw 1a is equal with the distance of connection round pin round pin 3 with the distance and the vice card chi jaw 2a that connect round pin 3 center of circle and be B, the ratio of A and B is constant K, and constant K is that Special caliper scale mark spacing enlargement ratio is detected in the present embodiment intermediate gap; Main card chi 1 links into an integrated entity by being connected round pin 3 with vice card chi 2, connecting round pin 3 can be rivet arrangement, by cooling after rivet hot, main card chi 1 and vice card chi 2 are linked into an integrated entity, also can be designed to other versions, main card chi 1 and vice card chi 2 are fitted closely and ensures that main card chi 1 can do the free gyration of gapless around being connected round pin 3 with vice card chi 2.
When main card chi jaw 1a overlaps with vice card chi jaw 2a, the scale mark of arrow 2d corresponding master calibration plate 1c is zero graduation line, and main card chi jaw 1a is identical with the calibration value of arrow 2d corresponding master calibration plate 1c high scale line with the actual air line distance that vice card chi jaw 2a opens; The point that scale mark intersects with master calibration plate 1c inner arc sideline is scale mark starting point, the point that zero graduation line and master calibration plate 1c inner arc sideline intersect is zero graduation line starting point, the demarcation value difference of adjacent scale mark is L, and demarcating value difference L can set according to pre-provisioning request.On master calibration plate, the air line distance difference of adjacent scale mark starting point and zero graduation line starting point is demarcate the product of value difference L and constant K; Further, the scale mark on master calibration plate 1c from inside to outside and ascendingly to mark.
In the present embodiment, main card chi jaw is identical with the shape of vice card chi jaw and section is circular arc, and when namely main card chi jaw overlaps with described vice card chi jaw arc-shaped surface is tangent, the scale mark of the corresponding described master calibration plate of arrow is zero graduation line.Certainly, the section of main card chi jaw and vice card chi jaw also directly can be designed to a roundlet salient point.
Lower mask body sets forth the setting of scale mark:
As main card chi jaw 1a and the tangent coincidence of vice card chi jaw 2a arc-shaped surface, scale mark corresponding with the arrow 2d on secondary scaleplate 2c on master calibration plate 1c, its calibration value is demarcated as zero; When the actual air line distance of main card chi jaw 1a and vice card chi jaw 2a is 1mm, indicating the scale mark calibration value on corresponding master calibration plate 1C to be also the scale mark starting point of 1mm, calibration value 1mm and the air line distance of zero graduation line starting point with arrow 2d is then K × 1mm.In like manner, when the actual air line distance of main card chi jaw 1a and vice card chi jaw 2a is S, indicating the scale mark calibration value on corresponding master calibration plate 1C to be the air line distance of S, S scale mark starting point and zero graduation line starting point too with arrow 2d is then K × S.It can thus be appreciated that, the air line distance of all scale mark starting points and zero graduation line starting point is the calibration value of this scale mark and the product of constant K, when the demarcation value difference of adjacent two scale marks is set to 0.2mm, then the air line distance difference of adjacent scale mark starting point and zero graduation line starting point is be then K × 0.2mm.
Shown in composition graphs 4, the using method of the present embodiment Special caliper is as follows:
1) the main card chi jaw 1a of Special caliper and vice card chi jaw 2a is put into target piece 4 notch that need measure, then main card chi jaw 1a and vice card chi jaw 2a is opened, make main card chi jaw 1a and vice card chi jaw 2a respectively with target piece 4 surface contact, stable private slide calliper rule position;
2) on the master calibration plate 1c of main card chi 1, read the scale mark calibration value corresponding with vice card chi 2 arrow 2d, namely complete the clearance measurement of target piece 4.
Application the present embodiment Special caliper, can complete rapidly the gap detection of such as vehicle arrangement privileged site, improves Site Detection operation work efficiency.
