Embodiment
As shown in Fig. 1 ~ Fig. 5, the large diameter combined measuring tool of a kind of measurement, comprises graduated cylinder 1, abutment ring 2, portion of the handle, retained part, measuring head 5, dial gauge 6.Graduated cylinder 1 is connected with portion of the handle by abutment ring 2, and retained part is arranged on portion of the handle, and measuring head 5, dial gauge 6 are arranged on retained part.
Described graduated cylinder 1 is multiple, and multiple graduated cylinder length is different; Described abutment ring 2 is multiple, is connected between adjacent two graduated cylinders by an abutment ring 2.Described portion of the handle is two, comprises head end portion of the handle 3, end portion of the handle 3 '; Described retained part is two and comprises head end retained part 4, distal gripping portions 4 '.Described head end portion of the handle 3 is provided with on head end retained part 4, described end portion of the handle 3 ' and distal gripping portions 4 ' is installed.Described head end retained part 4 is provided with measuring head 5, described distal gripping portions 4 ' is provided with dial gauge 6.
As shown in Figure 5, multiple graduated cylinder 1 is a series, can determine length dimension and the quantity of graduated cylinder 1 according to actual needs, and internal thread has been attacked at each graduated cylinder 1 two ends, and screw thread is fine thread, and the depth of thread is 20mm.Graduated cylinder is also provided with fixed orifice 7, for graduated cylinder is tightened, is connected by abutment ring 2 between graduated cylinder with graduated cylinder, because sometimes needing the diameter of measurement very large, so the material of graduated cylinder should be light as far as possible when proof strength, therefore graduated cylinder aluminium alloy material.
As shown in Figure 2, abutment ring 2 is an annulus of attacking outer round thread, and abutment ring 2 is threaded connection with graduated cylinder 1 or portion of the handle, rises and connects fastening effect.Described outer round thread is fine thread, and length is 36mm, and material is aluminium alloy.
As shown in Fig. 3 ~ 4, head end portion of the handle 3, end portion of the handle 3 ' are for installing retained part and being connected graduated cylinder 1, and each portion of the handle length is 150mm ~ 200mm, and portion of the handle end is provided with endoporus, and endoporus is provided with fine thread, and the degree of depth is 20.Portion of the handle is connected by abutment ring 2 with graduated cylinder 1, and portion of the handle is provided with fastener hole 7 ', is used for being connected with graduated cylinder 1.
Head end retained part 4, distal gripping portions 4 ' form by two parts symmetrical structure, the locating surface 15 that each retained part is arranged is used for two symmetric parts laminating location, first bolt hole 8 is used for fastening two retained parts, after ensureing pretension bolt 11, arc contact surface 13 is made to keep the gap of 0.3mm with the cylindrical of portion of the handle, the convenient adjustment position of retained part on portion of the handle, in time adjusting to desired location, the bolt at fastening second bolt hole 9 place makes retained part be positioned at completely on portion of the handle.First surface 14 is 0.5mm to the distance of arc contact surface 13, measuring head 5 and dial gauge 6 coordinate with the 3rd surface of contact 16, the gap of 0.1mm is kept with the 3rd surface of contact 16,3rd bolt hole 10 is used for being fixed on by measuring head 5 in the 3rd surface of contact 16, and leave the gap of 0.1mm, in order to be that internal diameter or external diameter select the position of measuring head 5 and the measuring head direction of dial gauge 6 according to what measure, then fastening bolt 11 is located.In order to convenient when pretension bolt, three nut 12 places that can coordinate at three bolts 11 arrange three hexagon counterbores and be used for positioning screw cap 12, nut 12 can not be rotated freely, pretension is got final product with an allen key, handled easily, two symmetrical retained parts are aluminum alloy materials, and a set of aided measurement device has two retained parts, one is used for installing and measuring 5, one and is used for installing dial gauge 6.
The diameter of measuring head 5 is arranged to consistent with the diameter of the holder of dial gauge 6, the 3rd surface of contact 16 of retained part can be made compatibility to be installed dial gauge 6 and measuring head 5, the two ends of measuring head 5 are the smooth fillet through special processing, make measuring head wear-resisting, ensure precision.
When operating, graduated cylinder 1 and retained part is spliced according to inside and outside diameter of a circle, then calibrate on the standard block gauge 17 spliced, need the portion of the handle that two people hold measurement mechanism two respectively, but it is significant to note that posture when calibrating of two people and dynamics should be consistent with when measurement, this is the key ensureing precision, also needs to calibrate again after measuring, and whether inspection has error.
