Abstract
The invention relates to a measuring instrument for large-diameter inner threads. The measuring instrument comprises a sleeve, a measuring rod, a center, a baffle and a spring, a steel ball is arranged at the head of the center, the center is fixed to one end of the sleeve, a flange is arranged at the other end of the sleeve, a containing cavity is formed in the sleeve and internally provided with the baffle capable of sliding, the baffle is connected with the sleeve through the spring, the other end of the baffle is connected with the measuring rod, the other end of the measuring rod is conical, and the measuring rod is further provided with a pier shoulder. The measuring instrument has the advantages of being convenient to use, high in efficiency and the like.
Description
Technical field
The present invention relates to field of measuring technique, particularly a kind of large diameter and inner thread measuring instrument.
Background technology
In internal thread fields of measurement, be substantially all adopt plug thread gauge or screw thread Calibration thread gauge to measure, the actual value of thread pitch diameter cannot be measured.Measuring instrument of the prior art can only detect less diameter of screw, cannot solve size screw thread diameter, and due to the problem of measured workpiece weight and measuring method, complex operation, efficiency is low, easily damages gauge head, also result in the heavy losses of cost.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of easy to use, efficiency is high, the large diameter and inner thread measuring instrument of long service life.
Realize technical scheme of the present invention as follows:
A kind of large diameter and inner thread measuring instrument, comprises sleeve, sounding rod, top, baffle plate and spring, described top head is provided with steel ball, top one end being fixed on sleeve, the sleeve other end is provided with flange, is provided with accommodating cavity in sleeve, is provided with the baffle plate that can slide in this accommodating cavity, baffle plate is connected by spring with sleeve, the baffle plate other end is connected with sounding rod, and the other end of sounding rod is set to taper shape, sounding rod is also provided with pier shoulder.
The diameter of described sounding rod is consistent with sleeve diameter, and advantage is convenient to sounding rod to fill in sleeve, the surveying instrument that never formation one is complete.
Described sleeve is provided with the set nut of fixation measuring bar, and advantage prevents sounding rod from sliding, and causes during measurement and occurs error.
Have employed above-mentioned scheme, sounding rod is loaded in sleeve, under the state of nature that sounding rod contacts with baffle plate, the distance at these instrument two ends and the distance between flange and pier shoulder is measured by outside micrometer, then holddown spring is passed through, first the conical end of sounding rod is placed in screw thread, then sleeve center point is placed in screw thread, steel ball on top can prevent from toply after touching screw thread, causing damage due to friction, by the bounce-back of spring, two ends are withstood in screw thread, again measure the distance between flange and pier shoulder with milscale; The difference of the distance of front twice measurement with after the sum of measured value be once the diameter of this threaded hole, only need once correct, just can measure batch.Easy to use, operation clear thinking, long service life, work efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is sleeve, and 2 is top, and 3 is steel ball, and 4 is sounding rod, and 5 is baffle plate, and 6 is spring, and 7 is flange, and 8 is pier shoulder, and 9 is set nut.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, a kind of large diameter and inner thread measuring instrument, comprises sleeve 1, sounding rod 4, top 2, baffle plate 5 and spring 6, described top 2 heads are provided with steel ball 3, top 2 one end being fixed on sleeve 1, and sleeve 1 other end is provided with flange 7, accommodating cavity is provided with in sleeve 1, be provided with the baffle plate 5 that can slide in this accommodating cavity, baffle plate 5 is connected by spring 6 with sleeve 1, and baffle plate 5 other end is connected with sounding rod 4, the other end of sounding rod 4 is set to taper shape, sounding rod 4 is also provided with pier shoulder 8.
The diameter of described sounding rod 4 is consistent with sleeve 1 internal diameter, and advantage is convenient to sounding rod 4 to fill in sleeve 1, thus the surveying instrument that formation one is complete.
Described sleeve 1 is provided with the set nut 9 of fixation measuring bar 4, and advantage prevents sounding rod 4 from sliding, and causes during measurement and occur error.
