The present invention relates to a kind of row pitch checking tool of readable, be specifically related to a kind of two pitch-rows of reading from cubing, belong to the cubing technical field.
Background technology
At present two apertures are measured to main dependence three-coordinates measuring machine or functional measurer, functional measurer is input rule namely, and whether the spacing that only can detect two apertures in the margin tolerance allowed, can not demonstrate concrete numerical value.
Summary of the invention
The object of the invention is to specifically to measure the row pitch checking tool of two aperture pitch readings.
According to technical scheme provided by the invention, a kind of row pitch checking tool of readable, comprise cubing and calibrating device;
Described cubing comprises a cubing main body, and described cubing main body top is provided with a dial indicators rack, and clock gauge is connected with dial indicators rack by fastening clamp; Also be provided with a spring cutting ferrule between fastening clamp and dial indicators rack; The clock gauge measuring head of described clock gauge is exposed on the cubing main body through dial indicators rack;
Described cubing main body top also is provided with a sliding shoe, and sliding shoe, over against the clock gauge measuring head, is positioned at clock gauge measuring head front end, and parallel with the axis direction of clock gauge measuring head; Also be provided with a test pin on described sliding shoe; The sliding shoe two ends are fixed with respectively the first fastening block and the second fastening block;
One end of described test pin is the test pin measuring junction, and the test pin measuring junction penetrates the below that the cubing main body is positioned at the cubing main body; Described cubing main body below also is provided with setting circle; Described setting circle is positioned at the dial indicators rack below;
Also comprise an independently calibrating device, described calibrating device left end is provided with a boss; Be provided with a circular hole on boss, opposite side is provided with a big hole.
Described fastening clamp is screwed.
Described the first fastening block and the second fastening block all are secured by bolts on the cubing main body.
The upper and lower two ends of described sliding shoe are provided with first groove; The position of corresponding the first groove of the first fastening block and the second fastening block is provided with the second corresponding groove; Two group of first groove and the second groove form two raceways.Be provided with several balls in described two raceways.
The diameter of described test pin measuring junction is less than the diameter of circular hole; The location diameter of a circle is less than the diameter of big hole.
Beneficial effect of the present invention: the present invention is simple in structure, can overcome existing measurer and only can provide the deficiency of qualitative conclusion, and a kind of row pitch checking tool of readable is provided.Its measuring method has been used existing clock gauge to measure, but popularity rate is high, has the prospect of industrial applications.
