Abstract
The invention discloses a method for measuring teeth distance of a tooth bar and paired tooth deviation, comprising steps drawing a tooth-formed graph according to technical parameters of the tooth bar and marking a tooth bar nodel line, 2) making a cycle between the two teeth, wherein the circle center of the cycle passes through the nodel line, the circle is tangent with adjacent teech surfaces and the diameter of the circle is d, 3) making a three-piece tool which is a steel tube with an outer diameter being d, 4) horizontally placing the tooth bar needed to be measured, wherein the tool is placed inside the teeth and the paired teeth which are needed to be measured, and the outer wall of the tool is in total contact with the tooth surface, 5) measuring teeth spaces, 6) measuring paired teeth deviation, and 7) repeating 4),5) and 6) to measure other teeth of the tooth bar. The step of measuring the teeth spaces comprise the step of measuring the outer rim space a between two adjacent tools and the teeth space is a-d, and the step of measuring tooth deviation comprises the step of compensating the measurement with a standard right angle ruler, wherein one edge of the right angle ruler is against to the outer rims of the two adjacent tools, the gap between one side of the standard right angle ruler and the tool inside the opposite tooth is b which is a deviation value of the paired teeth.
Description
Technical field
The present invention relates to and a kind ofly measure the space width of tooth bar and the method to tooth deviation.
Background technology
Ocean platform pile leg lifter rack belongs to large modulus tooth bar, and its accuracy requirement is higher.For the space width of tooth bar, the measurement to tooth deviation, the general measuring method adopting standard tooth form template at present, its shortcoming is: it is low that (1) measures efficiency; (2) measuring accuracy is poor.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of Measuring Oceanic platform tooth bar efficiency and the high space width of measurement tooth bar of precision and the method to tooth deviation.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind ofly measure the space width of tooth bar and the method to tooth deviation, comprises the steps,
1) according to the technical parameter of tooth bar, draw profile of tooth figure, mark pitch line;
2) make a circle in two tooth centre positions, make its center of circle by nodel line and tangent with two adjacent teeth face, determine this diameter of a circle d;
3) make three frocks, the steel pipe of frock to be external diameter be d, outer surface of steel tube is smooth;
4) the tooth bar horizontal positioned need measured, frock is put in adjacent two teeth that need measure and to tooth position, and the outer wall of frock is contacted completely with the flank of tooth;
5) space width is measured: with the outer rim spacing a of adjacent two frocks of vernier caliper measurement tooth bar homonymy, then space width is a-d;
6) tooth deviation is measured: with standard straight angle square conjunction measuring, standard straight angle square limit is close to the outer rim of adjacent two frocks of tooth bar homonymy simultaneously, another limit of standard straight angle square and to the gap width b between the frock outer rim of tooth position, this b value is exactly to tooth deviate;
7) repeat 4), 5), 6) measure other each tooth of tooth bar.
The end of described frock is welded with the plectane that diameter is D respectively, the vertical plectane in axis of steel pipe and through the plectane center of circle, wherein D is greater than d,
Space width measurement changes the outer rim spacing A with adjacent two plectanes of vernier caliper measurement tooth bar homonymy into, then space width is A-D;
When tooth deviation is measured, change the outer rim that standard straight angle square limit is close to adjacent two plectanes of tooth bar homonymy simultaneously into, another limit of standard straight angle square and to the gap width B between the plectane of tooth position, this B value is exactly to tooth deviate.
Described plectane offers two symmetrical semicircle orifices.
Chamfered outside described steel pipe two ends.
The invention has the beneficial effects as follows: measuring method is easy, the work efficiency of measurement is high; The data precision measured is higher.
Accompanying drawing explanation
Fig. 1 is the block diagram that the present invention measures the space width of tooth bar and the method to tooth deviation.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1, the space width of measurement tooth bar of the present invention and the method to tooth deviation, comprise the steps,
1) according to the technical parameter of tooth bar, draw profile of tooth figure, mark pitch line;
2) make a circle in two tooth centre positions, make its center of circle by nodel line and tangent with two adjacent teeth face, determine this diameter of a circle d;
3) make three frocks, the steel pipe of frock to be external diameter be d, outer surface of steel tube is smooth;
4) the tooth bar horizontal positioned need measured, frock is put in adjacent two teeth that need measure and to tooth position, and the outer wall of frock is contacted completely with the flank of tooth;
5) space width is measured: with the outer rim spacing a of adjacent two frocks of vernier caliper measurement tooth bar homonymy, then space width is a-d;
6) tooth deviation is measured: with standard straight angle square conjunction measuring, standard straight angle square limit is close to the outer rim of adjacent two frocks of tooth bar homonymy simultaneously, another limit of standard straight angle square and to the gap width b between the frock outer rim of tooth position, this b value is exactly to tooth deviate;
7) repeat 4), 5), 6) measure other each tooth of tooth bar.
The end of described frock is welded with the plectane that diameter is D respectively, the vertical plectane in axis of steel pipe and through the plectane center of circle, wherein D is greater than d, and in original Step d, after frock is put into tooth, promotes plectane, and make plectane be close to tooth bar side, placement speed is fast
