Abstract
The invention 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 survey instrument technical field.
Background technology
At present, measuring the Shaft testing degree of depth is mainly to use the mode of vernier caliper or pit gauge to measure, yet, because the degree of depth of keyway is to using the cylindrical bus of farthest axle of keyway plane as benchmark, and bus in keyway top adds to be cut at keyway and removes man-hour, so, when measuring often with the benchmark the most of the bus on the axle of keyway bottom, when measuring, sometimes must repeated multiple timesly measure, to guarantee to measure the actual grade of keyway, not only cumbersome, simultaneously owing to being subject to the impact of extraneous factor, there is sometimes larger measuring error.
Summary of the invention
The object of the invention is to: provide a kind of compact conformation, easy to use, measure a kind of mechanical keyway measuring mechanism not affected by extraneous factor, overcome the existing above-mentioned defect 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 comprised 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 a hand test handle on the top of test chart; In the lower end of test chart, be connected with a reference test bar, reference test bar is docked at the upper oral part of measuring staff locating piece by fore shaft cover, and is fixed by adjusting bolt; In the inner chamber bottom of measuring staff locating piece and the shoulder portion of depth measurement probe, be provided with a special-shaped spring, depth measurement probe connects through special-shaped spring one end and reference test bar, and the other end is through the measured hole of location plug screw; In the bottom of measuring staff locating piece, be connected with a location plug screw, location plug screw is fixed by shoulder screw.
Principle of work of the present invention is: in use need only opening on the cylindrical that grade position rides over axle measuring staff locating piece, and make the same portion of Sounding Rod align keyway, read at this moment the numerical value of dial gauge, then measuring staff locating piece is ridden over to any part of axle cylindrical, simultaneously, the head of depth measurement probe contacts with the cylindrical any part of axle, and reads the now reading value of dial gauge, and this difference of twice is exactly the depth value of keyway.
Beneficial effect of the present invention: the present invention have advantages of compact conformation, easy to use, measure and accurately, not affected by extraneous factor, particularly the present invention is without relative datum, can measure the degree of depth of various axle classes, effectively overcome the existing repeated multiple times measurement and owing to being subject to the impact of extraneous factor when measuring the axle class degree of depth of existing vernier caliper or pit gauge, had sometimes the defect of larger measuring error.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, structure of the present invention is described further.
Fig. 1 is structure principle chart of the present invention.
Shown in figure: 1, test chart; 2, hand test handle; 3, fore shaft cover; 4, reference test bar; 5, adjusting bolt; 6, measuring staff locating piece; 7, special-shaped spring; 8, location plug screw; 9, depth measurement probe; 10, shoulder screw.
