Abstract
The invention discloses a quick deep hole inner diameter measurement device. The quick deep hole inner diameter measurement device comprises an inner diameter vernier scale main scale, a vernier scale, an inner diameter movable scale, a gear rack drive pair, a universal coupling mechanism and an adjusting handle. One end of the inner diameter vernier scale main scale is a tip, and a front slide groove and a rear slide groove are arranged in the middle of the inner diameter vernier scale main scale along the axis. The vernier scale is mounted at the outer edge of the inner diameter vernier scale main scale, and the inner diameter movable scale is disposed in the rear slide groove of the inner diameter vernier scale main scale and fixedly connected with the vernier scale. A rack of the gear rack drive pair is fixed in the front slide groove of the inner diameter vernier scale main scale, and a gear is in shaft connection with the vernier scale. Besides, the gear of the gear rack drive pair is connected with the adjusting handle through the universal coupling mechanism, and a main handle is hinged at the tip of the inner diameter vernier scale main scale. The measurement device is capable of measuring inner diameter of internal deep holes quickly and accurately, so that production efficiency of precuts and accuracy of test results are improved greatly.
Description
Technical field
The present invention relates to the surveying instrument field, specifically refer to a kind of for measuring the measurement mechanism that inner deep hole internal diameter size can quick and precisely be measured.
Background technology
At present, add man-hour for the deep hole series products, because product internal diameter passage is longer, its measuring position has the singularity of locus restriction, can't accurately measure with ordinary measring tool for measuring inner deep hole internal diameter size.General commonly used method is by ruler manual observation pairing comparision or with internal diameter clamp mensuration, thereby quick and precisely whether the testing product internal diameter size meets the requirements, thereby greatly reduce production efficiency of products and precision of test result, and also increased the measurement difficulty.
Summary of the invention
Technical matters to be solved by this invention provides a kind of measurement mechanism that can quick and precisely measure for the inner deep hole internal diameter size of measurement, thereby has improved production efficiency of products and precision of test result greatly.
A kind of deep hole internal diameter rapid measurement device of the present invention, comprise: internal diameter vernier caliper main scale, vernier scale, the moving chi of internal diameter, rack-and-pinion transmission, universal coupling mechanism and adjusting handle, one end of described internal diameter vernier caliper main scale is most advanced and sophisticated, is provided with forward and backward two sliding trays along axis in the middle of the internal diameter vernier caliper main scale; On the internal diameter vernier caliper main scale outer rim vernier scale is housed, the moving chi of internal diameter places the sliding tray of internal diameter vernier caliper main scale rear side, and fixedlys connected with vernier scale; The tooth bar of rack-and-pinion transmission is fixed in the sliding tray of internal diameter vernier caliper main scale front side, and gear is connected for axle with vernier scale; The gear of rack-and-pinion transmission is connected with adjusting handle by universal coupling mechanism, by adjusting handle driven gear and tooth bar engaged transmission, thereby drives vernier scale and the moving chi associated movement of internal diameter.
Further improve, the place, tip of described internal diameter vernier caliper main scale also is hinged with main handle.
Further improve, the end of the moving chi of described internal diameter is most advanced and sophisticated again.
Beneficial effect of the present invention:
Ruler manual observation pairing comparision described in the prior art, this method can accurately reading numerical values, have bigger error; Another kind of described internal diameter clamp mensuration, operation is loaded down with trivial details, can not directly read measurement numerical value fast, when measuring reading numerical values, secondary also can have error, be directed to the weak point of these two kinds of methods, the present invention makes new design, measurement mechanism of the present invention is worked in coordination by main handle and adjusting handle, deep hole inner diameter measurement thing is placed measured position, but the optional position is regulated the deep hole internal diameter and is directly measured accurate value fast, and simple to operate, practical, thereby production efficiency of products and precision of test result have been improved greatly.
