Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1, multipurpose high-acruracy survey chi comprises: main scale 1, with the matching used attached chi 2 of main scale 1, centering calliper 3;
As shown in Figure 2, described main scale 1 comprises: the first inner diameter measurement pawl 5, first outside diameter measuring pawl 6, straight steel ruler 7, straight steel ruler locking device 8; The first described inner diameter measurement pawl 5, first outside diameter measuring pawl 6 is formed in one, and described straight steel ruler locking device 8 is fixedly arranged on main scale 1; Described main scale 1 is fixedly connected with straight steel ruler 7 by straight steel ruler locking device 8; Described straight steel ruler 7 is the straight steel ruler (or providing for oneself) of current commercially available different size.
Described attached chi 2 comprises: centering calliper 3, vernier scale 4, second inner diameter measurement pawl 9, second outside diameter measuring pawl 10, in length and breadth to slotting chi groove 11, in length and breadth to straight steel ruler locking device 12; Described centering calliper 3, second inner diameter measurement pawl 9, second outside diameter measuring pawl 10, be formed in one to slotting chi groove 11 in length and breadth, described is fixedly arranged on attached chi 2 to straight steel ruler locking device 12 in length and breadth; Described measures locking operate at the end of at straight steel ruler 7 by implementing both direction in length and breadth to slotting chi groove 11 to straight steel ruler locking device 12 in length and breadth.
Embodiment
Structure of the present utility model is divided into main scale 1, attached chi 2, take precision as the vernier scale of 0.02mm is example; 49 lattice on vernier scale 4 aim at 50 lattice on straight steel ruler 7, and each little lattice of the scale on straight steel ruler 7 are 1.0mm, and each the little lattice scale on vernier scale is 49/50=0.98mm; During by trip slide calliper rule 4 measuring workpieces, first see zero line on vernier is after straight steel ruler how many mm, and then see that vernier scale 4 Shang Na road graduation mark aims at the graduation mark on straight steel ruler 7.The zero line of such as vernier scale after 10mm, and then sees the graduation mark on the 10th road graduation mark aligning straight steel ruler on vernier scale, and the data namely measured are 10.20mm.As the graduation mark on vernier scale often differs lattice with the graduation mark of straight steel ruler, so, size just differs 0.02mm, differs 10 lattice, has namely just differed 0.20mm.
As Fig. 2, in Fig. 3 13, 14, shown in 15: when using the utility model, on known vernier caliper measurement testee and accurate reading measured value method basis, when main scale does the use of centering calliper in attached chi " longitudinally inserting chi groove ", tested circle 13 surface plane and centering calliper 3 liang of card arms of angle (4mm/H) are close to, straight steel ruler 7 is compressed and by tested circle 13 planar central, straight line section is drawn along straight steel ruler limit with 0.5mm/r scriber (pencil), form the straightway of style of writing width 0.5mm14, tested circular object is made to convert an angle again, said method is used again to mark intersection line segment, namely boost line 15 is measured in centering, two intersection line intersection points are the positioning centre point of tested circular object.
Determine shown in angle 16 as done drawing in Fig. 3: attached chi described in the utility model also not having to determine angle calliper use as drawing separately in main scale, straight steel ruler situation, can coordinate upright and outspoken chi to do drawing and determining the diversity that angle boost line 17 can expand drafting angle.
The utility model is developed centering calliper, is drawn and determine angle calliper multiple function in the conventional slide measure precision of maintenance and the constant basis of prototype, show: constant, the accurate locking any round central point of certainty of measurement constant (50 calibration), using method, accurately drafting 30 ° of 45 ° of 60 ° of 90 ° of 120 ° of multi-angle figures, the cheap commercially available straight steel ruler of efficiency utilization or the existing straight steel ruler of user and save commercially available slide measure costly fund of buying, can many specifications select 100,200,300mm straight steel ruler (being commonly called as Steel Ruler); With this possessed by any user can quick and precisely measure the internal diameter of testee, external diameter, the center of circle, length, thick, draw and determine measurement and the drafting of angle, the utility model makes common calliper variable body be of many uses, directly perceived, accurate, light and handy, convenient, the measurement measurer of saving fund, has greatly expanded the utilization rate of commercially available survey tool.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its objective is and familiar user of service can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalents done by the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
