Abstract
The utility model relates to measuring equipment for precision parts, in particular to a coaxiality measuring instrument. The coaxiality measuring instrument comprises a pair of driving main shafts, which is arranged on an instrument main body and is synchronously controlled by a synchronous mechanism to rotate; measuring heads and positioning datum planes are respectively and correspondingly arranged at the inner ends of the driving main shafts; and a sensor measuring head is arranged above the position between the measuring heads. According to the coaxiality measuring instrument, the defects that the traditional measurement of the coaxiality and the jitter is realized by mainly adopting a runout jitter instrument, the coaxiality measuring instrument or roundness measuring equipment are mainly overcome; the coaxiality measuring instrument with an inner hole as the reference has a wide practical value in the work procedure detection of large-batch fine parts as well as a popularization value; the measurement problem in the field is solved; and the gap in the field is made up.
Description
Technical field
The utility model relates to the measuring equipment of precision component, particularly a kind of axiality measuring apparatus.
Background technology
The right alignment of existing precision component, the measurement of beating mainly are to adopt beat beat instrument or axiality measuring apparatus or and roundness measuring equipment.But they have following defective respectively.
Beat beat instrument be with the center pit be benchmark carry out to foreign round right alignment and the measurement of diameter run-out, be to measure to the axial workpiece that does not have center pit.
Existing axiality measuring apparatus is the axiality measuring apparatus of a new generation of representative with the axiality measuring apparatus that the global company of the U.S. produces.It can remedy the beat defective of instrument of beat, and it is to be that benchmark is measured with the right alignment of endoporus to foreign round with the cylindrical, also can be to the pulsation measurement of end face.But little to endoporus, to the endoporus sphere certain some right alignment to foreign round can not measure, can not be benchmark coaxality measurement to foreign round with the endoporus.
The roundness measuring equipment Measuring Time is long, measures the cost height, and the incompatibility operation detects.The limitation that it is also arranged simultaneously for small-bore, specific region, shape, can not be measured.
Accurate tiny axial workpiece has the many measurements that can not use above-mentioned instrument to carry out right alignment, beat in automobile, electronics, aviation industry, they often adopt the map instrument to measure, or the conversion benchmark is measured, this does not meet the definition of form and position tolerance, can not ensure the quality of products, for manufacturing and the judgement of product quality brings a very big difficult problem.
The utility model content
The purpose of this utility model is to provide a kind of axiality measuring apparatus, it mainly solves the right alignment of existing precision component, the measurement of beating, mainly be adopt beat beat instrument or axiality measuring apparatus or and the existing defective of roundness measuring equipment, this is that the axiality measuring apparatus of benchmark has wide practical value with the endoporus in the large batch of operation of fine parts detects, solved the measurement difficult problem in this field, remedy the blank in this field, had the value of popularization.
The utility model solves the problems of the technologies described above the technical scheme that is adopted.
A kind of axiality measuring apparatus is characterized in that: it comprises a pair of transmission main shaft that is rotated by the synchronizing linkage synchro control that is arranged on the apparatus subject, and this transmission main shaft the inner correspondence respectively is provided with measuring head and positioning reference plane; The top, position has the sensor side head between the described measuring head.
Described axiality measuring apparatus, it is characterized in that: described synchronizing linkage comprise the synchronizing wheel that is arranged on the transmission main shaft outer end, comprise that also the two ends that are arranged on main body below also have the universal driving shaft of synchronizing wheel, the synchronizing wheel on the described transmission main shaft is connected interlock with synchronizing wheel on the adjacent universal driving shaft by bindiny mechanism.
The beneficial effects of the utility model are: the utility model is that the right alignment of benchmark has wide practical value with the endoporus in the large batch of operation of fine parts detects, not only solved the measurement difficult problem in this field, and be a kind of innovation of new type measuring instrument device.Remedy the blank in this field, had the value of popularization.
