Abstract
The utility model discloses an inner and outer circle detector, which mainly comprises supporting legs, a pedestal, a supporting block and a supporting shaft. The pedestal, the supporting block and the supporting shaft are fastened together through screws. Two ends of the supporting shaft are respectively provided with a bearing. The front end and one side of the pedestal are respectively provided with a stand column, a beam, a link block, a fixture block and a micrometer gauge or dial indicator. The inner and outer circle detector can be used to detect circular degree and oval maximum and minimum points of inner and outer circles of a workpiece. The inner and outer circle detector provided by the utility model has a simple structure, is rapid and accurate, and is mainly used for detection of inner and outer circles of a tubular type workpiece.
Description
Technical field
The utility model relates to a kind of inside and outside circle pick-up unit.
Background technology
To the circularity of large cylinder type Workpiece inspection cylindrical and inner circle, ellipse etc., major part is all to carry out the multiple spot measurement of comparison by milscale, vernier caliper, inside diameter caliper etc., and Measuring Time is longer, and efficient is lower, accuracy is not high.Particularly when the workpiece precision prescribed is very high, use milscale, vernier caliper, inside diameter caliper to can not meet requirement.So, developed a kind of inside and outside circle pick-up unit, mainly to cylinder type workpiece test circularity, ellipse etc., its precision is high, and is easy to operate, and checkability is high.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of simple in structure, detection efficiency is higher, it is fast to regulate the speed and the high a kind of inside and outside circle pick-up unit of accuracy.
For solving the problems of the technologies described above, a kind of inside and outside circle pick-up unit of the present utility model mainly comprises base, leg, rest pad and bolster, it is characterized in that: described base is fixed by three supporting legs, base, rest pad and bolster are in the same place by fastened by screw, and bolster two ends respectively are provided with bearing; Respectively be provided with column, crossbeam at base front end and a side, hinged by contiguous block at column and crossbeam, crossbeam one side is provided with fixture block, and clock gauge or dial gauge are hinged by fixture block and crossbeam.
As a kind of improvement of the present utility model, described take bearing as the point supporting workpiece, can axial rotation.
As a kind of improvement of the present utility model, described base front end and a side are respectively equipped with column, crossbeam etc., the circularity by clock gauge or dial gauge measuring workpieces inside and outside circle and the numerical value such as oval.
The utility model is simple in structure, and is convenient to use, can survey circularity and the oval numerical value that waits of Workpiece internal-external circle, accurately and reliably.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises base 2, base 2 has three legs 1, be respectively equipped with two rest pads 3, column 11,12 on base 2, its rest pad 3 tightens together by screw 17 with bolster 4, base 2, bolster 4 two ends respectively are provided with bearing 5, and workpiece 6 is placed on bearing 5 rotatable, and wherein rest pad 3 and bolster 4 can be adjusted according to the size of workpiece 6 external diameters; Its column 11 is hinged by contiguous block 10 with crossbeam 9, and crossbeam 9 one sides are provided with fixture block 7, and clock gauge or dial gauge 8 are hinged by fixture block 7 and crossbeam 9; Its column 12 is hinged by contiguous block 15 with crossbeam 14, and crossbeam 14 1 sides are provided with fixture block 16, and clock gauge or dial gauge 13 are hinged by fixture block 16 and crossbeam 14.
When [0011] using, at first to adjust rest pad 3 and bolster 4 according to the size of survey workpiece 6 external diameters, after confirmation, fastening by screw 17 and base 2; Adjust respectively contiguous block 10,15, crossbeam 9,14, fixture block 7,16 and clock gauge or dial gauge 8,13, make clock gauge or dial gauge 8,13 respectively with workpiece 6 Surface Verticals.By workpiece 6 slow rotation on bearing 5, can read by clock gauge or dial gauge 8,13 pointer circularity and oval maximum point and the smallest point of workpiece 6 inner circles and cylindrical.
