Abstract
The invention discloses a caliper for key slot inspection and a realizing method. The caliper comprises a caliper body, a fixed jaw and equipments for measurement and control, wherein the caliper body is respectively provided with the fixed jaw and a movable jaw, and the equipments for measurement and control are arranged on the two outside ends of fixed jaw and the movable jaw; and digital readout zero setting adjustment blocks for zero setting adjustment are respectively arranged between the equipments for measurement and control the fixed jaw as well as between the movable jaw and the equipments for measurement and control. The caliper for key slot inspection is simple and compact in structure, and small, exquisite and beautiful in measure; furthermore, the measuring results are intuitively displayed by numbers, so that the caliper is convenient to use, high in measurement precision, reliable in measurement, and reduces the labor intensity; according to the caliper, the problems that a common symmetry measurement gauge can not meet the symmetry inspection and measurement requirements of the key slots of the shaft parts with large diameters can be solved.
Description
Technical field
The present invention relates to measurer, particularly relate to slide calliper rule and implementation method for keyway check.
Background technology
Symmetry is an important form and position tolerance of part processing, and it affects the quality of product, is being related to the serviceable life of equipment.Traditional axle class symmetry detects as shown in Figure 1, is that axle 2 is placed on V1 shape piece, uses the gauge block 3 equating with width of keyway to be placed in keyway, measures with dial gauge 4.Or extended to come as shown in Figure 2 and Figure 3 by it, formed by orienting sleeve, main body V-shape base, rotation pressing plate, knurled nut, support bar, dial gauge; Concrete operations are rotation knurled nuts 5 and rotate pressing plate 4, V-shape base is placed on tested axle journal, go back to and rotate pressing plate 4, rotation knurled nut 5 fixes V-shape base 2, then transfers lever indicator gauge head, and it is contacted with at the bottom of keyway, precession trip bolt 3, orienting sleeve 1 is fastened on main body V-shape base 2, makes it play up and down, can only rotate; Again the pointer of dial gauge is preset to zero-bit, in groove, turns round 180, occur as pointer has the numerical value of offset from zero, adjust main body V-shape base, make dial gauge be shown as zero, represent that keyway baseplane is vertical with orienting sleeve 1; Unclamping trip bolt 3 upwards carries orienting sleeve 1 according to actual needs, allow gauge head contact on a side of keyway, precession trip bolt 3 again, orienting sleeve 1 is only rotated, on 2 positions of symmetry 180, measure the difference of reading a of key slot side, the symmetry error value in this cross section is f=axhd-h, and wherein d is the diameter of axle, and h is that keyway is dark; Same procedure is measured the symmetry error value in keyway other end cross section.Be exactly to be placed on lathe in addition, axle two ends are withstood with dial gauge and are placed on lathe saddle and pull measurement with thimble.More than measure the problem that exists step complexity can only measure and measure for smallclothes time, because workpiece will move, unsettled, measurement data can not be directly perceived, checks for major diameter key slot symmetry degree of shaft part, just require great effort very much, conventional symmetry measurement cubing can not meet measurement requirement thus.The product the present invention relates to is major diameter axial workpiece, and its diameter more than 400mm, for main equipment, bears the occasion that torque ratio is larger mostly.So the symmetry requirement to keyway is very high, is generally 0.03mm.If keyway symmetry does not reach requirement, keyway is fragile, and difficulty is repaired in lifting; In addition, on keyway, key works to connect transmit force, will make equipment work time not reach desirable design effect, and reduces serviceable life.
Summary of the invention
Object of the present invention is exactly that a kind of slide calliper rule and implementation method for keyway check will be provided, and it can overcome existing major diameter key slot symmetry degree of shaft part and measure the existing above problem of cubing.The object of the present invention is achieved like this, for slide calliper rule and the implementation method of keyway check, comprise that blade, fixed claw, measuring and controlling equipment form, it is characterized in that: on blade, be respectively arranged with fixed claw, movable claw, two ends, outside at fixed claw, movable claw are respectively arranged with measuring and controlling equipment, its method of operating is: fixed claw and movable claw are close to behind keyway two sides to locking movable claw; Adopt that digital display zero setting adjustment block is separately positioned between measuring and controlling equipment and fixed claw, carry out zero setting adjustment between movable claw and measuring and controlling equipment; Mobile two ends measuring and controlling equipment is to outer surface of workpiece respectively, and reading numerical values is A, numerical value B, and (numerical value A mono-numerical value B>/2 is symmetry error.
The present invention is simple in structure, compact, measurer is small and exquisite, attractive in appearance, measurement result is by digital intuitive display, easy to use, measuring accuracy is high, and measures reliably, has reduced labour intensity.The present invention has well solved conventional symmetry measurement cubing can not meet the problem to keyway checking measurements requirement.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described,
For slide calliper rule and the implementation method of keyway check, comprise that blade 1, fixed claw 2, measuring and controlling equipment 5 form, it is characterized in that: on blade 1, be respectively arranged with fixed claw 2, movable claw 3, be respectively arranged with measuring and controlling equipment 5 at the two ends, outside of fixed claw 2, movable claw 3; Its method of operating is: fixed claw 2 and movable claw 3 are close to behind keyway two sides to locking movable claw 3; Adopt that digital display zero setting adjustment block 4 is separately positioned between measuring and controlling equipment 5 and fixed claw 2, carry out zero setting adjustment between movable claw 3 and measuring and controlling equipment 5, mobile two ends measuring and controlling equipment 5 is to outer surface of workpiece respectively, and reading numerical values is A, numerical value B, (numerical value A mono-numerical value B)/2 are symmetry error.
Concrete implementation step:
1: fixed claw and movable claw are close to behind keyway two sides, locking movable claw, as shown in Figure 2;
2: adopt digital display zero setting piece to make two ends measuring and controlling equipment zero setting, after zero setting, remove digital display zero setting piece, as accompanying drawing 3 digital display zero setting pieces make as shown in the measuring and controlling equipment zero setting of one end;
