Abstract
The utility model discloses a quincuncial hole measuring device. The quincuncial hole measuring device comprises a measuring arc and two positioning rings, wherein the diameter of each positioning ring is equal to the diameter of the measuring arc; the two positioning rings are connected with a screw respectively; the two screws are in sleeved connection with a nut; the nut and the two screws have opposite thread matching directions; the two positioning rings are respectively connected with an inside micrometer respectively; and the inside micrometer penetrates through circular centers of the two positioning rings. The quincuncial hole measuring device can measure the maximum value between arcs inside a quincuncial hole conveniently, can position a measuring point accurately and has high precision of a measured value.
Description
Technical field
The utility model relates to a kind of measurement mechanism, is mainly used in the measurement plum blossom hole.
Background technology
The frame of mill is provided with plum blossom hole, after processing plum blossom hole, need measure its machining precision, and wherein an important index is the ultimate range between the circular arc in the plum blossom hole.Prior art adopts measurer directly to measure, and sees Fig. 1, and frame 3 inside are processed with plum blossom hole, ultimate range between needs measurement circular arc 2 and circular arc 4 can directly be measured with milscale 1, owing to be manually to determine measurement point, cause error bigger, can't accurately reflect the maximal value that to survey.
Summary of the invention
The utility model is studied and is improved at the prior art above shortcomings, and the plum blossom hole measurement mechanism is provided.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model comprises the measurement circular arc, it is characterized in that comprising two centring rings, the diameter of centring ring and the equal diameters of measuring circular arc, two centring ring difference connecting screw rods, nut of two screw rod sockets simultaneously, nut cooperates directions opposite with two screw flights, and two centring rings connect micrometer inside caliper respectively, and the internal diameter micrometer inside caliper is simultaneously through the center of circle of two centring rings.
Further, centring ring is connected with briquetting by screw, and guide rod has been passed in the joint portion between briquetting and the centring ring, and the two ends of guide rod are passed respectively and are installed in two briquettings on the centring ring, two guide rods are set between two centring rings, and guide rod is parallel with the center of circle connecting line of two centring rings.
Technique effect of the present utility model is: it is convenient to measure, and can the accurate in locating measurement point, the precision height of measured value.

Embodiment
See Fig. 2, Fig. 6, the utility model comprises two centring rings 5, and the arc diameter in the diameter of centring ring 5 and the plum blossom hole equates.Briquetting 6 is connected with centring ring 5 by left and right two screws 14, guide rod 8 passes the joint portion between briquetting 6 and the centring ring 5, two briquettings 6 that are installed on the centring ring 5 are passed at the two ends of guide rod 8 respectively, two guide rods 8 are set between two centring rings 5, and guide rod 8 is parallel with the center of circle connecting line of two centring rings 5.Micrometer inside caliper 7 is connected with upper and lower two centring rings 5 respectively, and micrometer inside caliper 7 is through the center of circle of two centring rings 5.See Fig. 5, upper and lower two centring rings 5 are connecting screw rod 9 and screw rod 13 respectively, screw rod 9 is by universal joint 10 connecting screw rods 11, screw rod 11 and screw rod 9 socket setting nuts 12, the threaded engagement direction of two ends up and down of setting nut 12 is opposite, rotation adjusting setting nut 12 can be controlled the distance between screw rod 11 and the screw rod 9, and then regulates two relative distances between the centring ring 5.
When the utility model uses, see Fig. 2 or Fig. 4, two centring rings 5 are chimeric respectively at two circular arc inside surfaces to be measured, and by the final position of rotation setting nut 12 definite centring rings 5, guide rod 8 can be to the mobile position-limiting action that plays of centring ring 5 then.Can measure the distance of center circle of two centring rings 5 this moment easily by micrometer inside caliper 7, measured center of circle distance value adds that arc diameter is two maximal values between the circular arc.
