Description
Technical field
The utility model relates to a kind of multifunctional measuring tool, particularly relates to a kind of slide calliper rule with right alignment and symmetry measurement.
Background technology
Since securing member was produced, in order to guarantee its steady quality, people had just invented multiple measurement measurer.These measurers are to guarantee one of securing member quality conditio sune qua non, as micrometer inside caliper, outside micrometer, vernier caliper, dial gauge etc.Because the function of common calliper on measuring is limited, especially very difficult on measurement right alignment and symmetry, old friends can only carry out on large-scale, more professional surveying instrument, and are time-consuming.In producing at the scene as hot pier worker when the right alignment of testing product, because the on-the-spot instrument that does not have to measure specially right alignment in workshop, so adopt the method for measuring indirectly, but these method measuring accuracy that adopt are poor, error is big, and also may there be certain difference in the result of reading when everyone measured, and the measurement easily and efficiently that realizes the product right alignment in therefore producing at the scene is one and remains to be dealt with problems.
Therefore, how the right alignment of convenient, fast measurement products is a difficult point in securing member is measured, and in order to solve this difficult problem, realizes accurately, the right alignment of measurement standard spare easily and efficiently.The utility model---coaxiality caliper is transformed on the common calliper basis and is formed, increased new function by transformation, it not only can measure accessory size as common calliper, can also be used for measuring the function that the common slide calliper rule such as right alignment, symmetry of part do not have, be very easy to workman and checker and measure right alignment, symmetry of part etc., for it provides a survey instrument easily and efficiently.
The utility model content
The utility model is by improving on the basis of common calliper and increasing, make it increase measure functional, thereby can be used to measure the right alignment and the symmetry of securing members such as Philips screw and six side's screws, and the while self has the function of common calliper, in the measurement of use that can be convenient and reliable multiple functions such as right alignment of product in machining, thereby improved the precision of the measurements such as right alignment of product in the machining greatly.
The technical solution of the utility model: a kind of right alignment vernier caliper that has multifunctional measuring, it comprises inner measuring jaw pair (1), outer measuring jaw pair (2), trip bolt (3), vernier scale (4), chi frame (5) and pit gauge bar (6) (see figure 1).Its architecture advances is measuring jaw pair (2) outside mainly, the same end face of the large and small pawl of measuring jaw pair (2) is marked with the scale of measurement products right alignment and symmetry outside, the big pawl of outer measuring jaw pair (2) has groove, the bottom of groove and the step width on top are c, and groove depth is b, and width is a, this groove can be (see figure 4)s such as the rectangular-shaped (see figure 2) of step, step semicircle arcuation (see figure 3), step triangular shape, also can not slot, directly stretch out a hook in the bottom, the length of hook is the c (see figure 5).The measure portion of the secondary unguiculus of outer measuring jaw is trapezoidal, and measuring head is positioned at trapezoidal bottom, and measuring the face height is E, and measuring the face width degree is F, when the face of measurement height E size is big and measure face width degree F size hour, is used to measure the endoporus and the outer circles (see figure 6) of part; Face height E size is little and measure face width degree F size when big when measuring, and is used to measure the right alignment (see figure 7) of cylindrical and the peripheral groove and the cylindrical of part.
During use, the measurement face of the end of tested part head being close to the big pawl of outer measuring jaw pair (2), the head of tested part is positioned at big pawl groove, and the measuring head of outer measuring jaw pair (2) unguiculus is put in the center pit of tested part head, promptly can read the right alignment and the symmetry size of tested part.
Compare with existing technology, because measuring jaw pair (2) is marked with scale outside, realization is to the measurement of the common size of part, and can also right alignment convenient, fast, measurement products exactly, symmetry, solved medium and small specification standards part product right alignment and symmetry effectively and measured difficult problem.Compare the instrument of special-purpose measurement right alignment, this right alignment vernier caliper can be realized the same function, and slide calliper rule are simple in structure, and low cost of manufacture is easy to use, easily-learned easily mastered.
