Abstract

The utility model discloses a lever-type measuring instrument for measuring the diameter of a deep hole. The measuring instrument comprises a movable probe, an equal armed lever, a long tube, a dial indicator, a handle, an elastic device, and a fixed probe. The long tube is fixed on the handle. The equal armed lever is fixed in the long tube. The lower probe of the dial indicator passes through the handle and the long tube and then contacts the upper right end face of the equal armed lever. The movable probe is fixed on the long tube and contacts the upper left end face of the equal armed lever. The fixed probe is fixed on the long tube and is axially symmetrical with the movable probe. The elastic device is fixed in the long tube and close to the movable probe. The two ends of the elastic device respectively contact the inner wall of the long tube and the lower right end face of the equal armed lever. With the above manner, the lever-type measuring instrument is capable of accurately measuring the diameter of a deep hole and has advantages of high measuring precision, good versatility, convenient and fan measurement, and simpleness and practicality.

Description

A kind of lever deep hole measuring apparatus of diameter
Technical field
The utility model relates to a kind of deep hole diameter measuring device field, particularly relates to a kind of lever deep hole measuring apparatus of diameter.
Background technology
The measurement of deep hole diameter is the difficult problem in measuring always, common inside diameter caliper is due to the restriction that is subject to measuring condition, can't be applied to the deep hole diameter measurement, and the deep hole internal diameter scale of special complete equally belongs to expensive instrument with other precision measuringtolls, expensive comparatively speaking, and measure inaccurately because of the coarse injustice of workpiece machining surface during roughing, easily make gauge head wearing and tearing, shorten its serviceable life.
The utility model content
The technical matters that the utility model mainly solves is to provide a kind of lever deep hole measuring apparatus of diameter, can measure accurately the deep hole diameter, has advantages of that measuring accuracy is high, versatility good, it is convenient and swift, simple and practical to measure.
for solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of lever deep hole measuring apparatus of diameter is provided, comprise: movable gauge head, bascule, long tube, clock gauge, handle, elastic device and fixing gauge head, described long tube is fixed in handle, be fixed with bascule in described long tube, it is inconsistent that the lower end gauge head of described clock gauge passes the upper right end face of handle and long tube and bascule, described movable gauge head is fixed on long tube and is inconsistent with the upper left end face of bascule, described fixedly gauge head is fixed on long tube and is axially symmetrical with movable gauge head, described elastic device is fixed near in the long tube of activity probe location, the two ends of described elastic device are inconsistent with the right lower end surface of the inwall of long tube and bascule respectively.
Preferably, described elastic device is spring, and described long tube lower end is provided with gib screw, and spring is equipped with in described gib screw upper end.
The beneficial effects of the utility model are: a kind of lever deep hole of the utility model measuring apparatus of diameter, can measure accurately the deep hole diameter, and have advantages of that measuring accuracy is high, versatility good, it is convenient and swift, simple and practical to measure.
Description of drawings
Fig. 1 is the structural representation of a kind of lever deep hole of the utility model measuring apparatus of diameter one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, movable gauge head; 2, bascule; 3, long tube; 4, clock gauge; 5, handle; 6, elastic device; 7, fixing gauge head.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises:
a kind of lever deep hole measuring apparatus of diameter, comprise: movable gauge head 1, bascule 2, long tube 3, clock gauge 4, handle 5, elastic device 6 and fixing gauge head 7, described long tube 3 is fixed in handle 5, be fixed with bascule 2 in described long tube 3, the lower end gauge head of described clock gauge 4 passes handle 5 and long tube 3 is inconsistent with the upper right end face of bascule 2, described movable gauge head 1 is fixed on long tube 3 inconsistent with the upper left end face of bascule 2, described fixedly gauge head 7 is fixed on long tube 3 axially symmetrical with movable gauge head 1, described elastic device 6 is fixed in the long tube 3 of close movable gauge head 1 position, the two ends of described elastic device 6 are inconsistent with the right lower end surface of the inwall of long tube 3 and bascule 2 respectively.
Described elastic device 6 is spring, and described long tube 3 lower ends are provided with gib screw, and spring is equipped with in described gib screw upper end.
Before measurement, with the ring gauge check and correction clock gauge 4 in standard aperture and allow its pointer zeroing, then the measuring instrument of zeroing is being put in the hole that needs to measure, reading on clock gauge 4 is exactly the deviation in aperture, reading is in the dimensional tolerance range of regulation, and size is qualified, otherwise defective.
A kind of lever deep hole of the utility model measuring apparatus of diameter can be measured the deep hole diameter accurately, has advantages of that measuring accuracy is high, versatility good, it is convenient and swift, simple and practical to measure.
The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
