Description
Technical field
The utility model relates to the surveying instrument field, specifically refers to a kind of measurement mechanism that can quick and precisely measure for the inner deep hole internal diameter size of measurement.
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 carry out Measurement accuracy with ordinary measring tool for measuring inner deep hole internal diameter size.General method commonly used is by ruler manual observation pairing comparision or uses the inside callipers mensuration, thereby quick and precisely whether the testing product internal diameter size meets the requirements, thereby greatly reduce the production efficiency of product and the accuracy of test result, and also increased the measurement difficulty.
The utility model content
Technical problem to be solved in the utility model provides a kind of measurement mechanism that can quick and precisely measure for the inner deep hole internal diameter size of measurement, thereby has greatly improved the production efficiency of product and the accuracy of test result.
A kind of deep hole internal diameter rapid measurement device described in the utility model, 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 is fixedly 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 that axle is connected 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.
The beneficial effects of the utility model:
Ruler manual observation pairing comparision described in the prior art, the method can accurately reading numerical values, have larger error; Another kind of described inside callipers mensuration, operation is loaded down with trivial details, can not directly read fast measurement numerical value, when the double measurement reading numerical values, also can there be error, be directed to the weak point of these two kinds of methods, the utility model is made new design, measurement mechanism described in the utility model is worked in coordination by main handle and adjusting handle, deep hole internal diameter is measured thing place measured position, but the accurate value of the direct Quick Measurement of deep hole internal diameter is regulated in the optional position, and simple to operate, practical, thereby the production efficiency of product and the accuracy of test result have greatly been improved.

Embodiment
As shown in Figure 1, a kind of deep hole internal diameter rapid measurement device described in the utility model, comprise: internal diameter vernier caliper main scale 1, vernier scale 2, the moving chi 3 of internal diameter, rack-and-pinion transmission 4, universal coupling mechanism 5 and adjusting handle 6, one end of described internal diameter vernier caliper main scale 1 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 1; On internal diameter vernier caliper main scale 1 outer rim vernier scale 2 is housed, it is used for reading on the internal diameter vernier caliper main scale 1 a certain scale mark and aims at number of division on the vernier scale 2; The moving chi 3 of internal diameter places the sliding tray of internal diameter vernier caliper main scale 1 rear side, and is fixedly connected with vernier scale 2, and the moving chi 3 of internal diameter is fixedly connected with vernier scale 2; The tooth bar of rack-and-pinion transmission 4 is fixed in the sliding tray of internal diameter vernier caliper main scale 1 front side, and gear is connected for axle with vernier scale 2; The gear of rack-and-pinion transmission 4 is connected with adjusting handle 6 by universal coupling mechanism 5, by adjusting handle 6 driven gears and tooth bar engaged transmission, thereby drive vernier scale 2 and moving chi 3 associated movements of internal diameter, when the moving chi 3 of internal diameter all contacts with internal diameter with the tip at internal diameter vernier caliper main scale 1 two ends, take out this measurement mechanism, namely can read concrete measurement numerical value; The place, tip of internal diameter vernier caliper main scale 1 is hinged main handle 7 also, and main handle 7 can be worked in coordination with adjusting handle 6, and the deep hole internal diameter measurement mechanism is placed measured position, but the direct Quick Measurement value of deep hole internal diameter is regulated in the optional position.
The utility model provides a kind of thinking and implementation method of deep hole internal diameter rapid measurement device; concrete application approach is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
