Abstract
The utility model provides a mechanical keyway measuring mechanism. A hand-press-type testing handle is arranged on the top end of a testing meter. A testing rod is connected to the lower end of the testing meter. The testing rod is docked with an upper port part of a testing rod positioning block through a locking muzzle and is fixed by an adjusting bolt. A special-shaped spring is arranged in the lower part of an inner cavity of the testing rod positioning block and on a shoulder of a depth measuring probe. The depth measuring probe penetrates through the special-shaped spring. One end of the depth measuring probe is docked with the testing rod while the other end of the depth measuring probe is penetrated through a measuring hole of a positioning plug screw. The positioning plug screw is connected to the lower part of the testing rod positioning block. The positioning plug screw is fixed by a shoulder screw.
Description
Technical field
The present invention relates to a kind of keyway measuring mechanism, particularly a kind of mechanical keyway measuring mechanism belongs to the survey instrument technical field.
Background technology
At present, measuring the axle class detection degree of depth mainly is to use the mode of vernier caliper or pit gauge to measure, yet, because the degree of depth of keyway is as benchmark with the cylindrical bus of the farthest axle on keyway plane, add to be cut man-hour at keyway and remove and be in bus above the keyway, so, when measuring often with the benchmark the most of the bus on the axle of keyway bottom, when measuring, sometimes must repeated multiple times measure, to guarantee to measure the actual grade of keyway, not only cumbersome, owing to be subjected to the influence of extraneous factor, there is bigger measuring error sometimes simultaneously.
Summary of the invention
The objective of the invention is to: provide a kind of compact conformation, easy to use, measure a kind of mechanical keyway measuring mechanism not influenced by extraneous factor, overcome the existing above-mentioned defective of existing vernier caliper.
The technical solution adopted for the present invention to solve the technical problems is: a kind of mechanical keyway measuring mechanism, it is made up of test chart, hand test handle, fore shaft cover, reference test bar, adjusting bolt, measuring staff locating piece, special-shaped spring, location plug screw, depth measurement probe, shoulder screw, and described keyway measuring mechanism is provided with hand test handle on the top of test chart; Be connected with a reference test bar in the lower end of test chart, reference test bar is docked at the upper oral part of measuring staff locating piece by the fore shaft cover, and by regulating bolt; Be provided with a special-shaped spring in the inner chamber bottom of measuring staff locating piece and the shoulder portion of depth measurement probe, the depth measurement probe passes special-shaped spring one end and reference test bar connects, and the other end passes the measured hole of location plug screw; Be connected with a location plug screw in the bottom of measuring staff locating piece, the location plug screw is fixed by the shoulder screw.
Principle of work of the present invention is: in use need only with the measuring staff locating piece open grade position ride over the axle cylindrical on, and make the same portion of Sounding Rod align keyway, read the numerical value of dial gauge at this moment, then the measuring staff locating piece is ridden over any part of a cylindrical, simultaneously, the head of depth measurement probe contacts with the cylindrical any part of axle, and reads the reading value of dial gauge this moment, and this difference of twice is exactly the depth value of keyway.
Beneficial effect of the present invention: the present invention have compact conformation, easy to use, measure the advantage not influenced by extraneous factor, particularly the present invention need not relative datum, can measure the degree of depth of various axle classes, effectively overcome existing vernier caliper or pit gauge existing repeated multiple times when measuring the axle class degree of depth and measured the influence that reaches owing to being subjected to extraneous factor, had the defective of big measuring error sometimes.
