Description
Technical field: the present invention relates to measurer, particularly relate to the slide calliper rule and the method for operating that are used for the check of major diameter key slot symmetry degree of shaft part in the measurer.
Background technology: symmetry is an important form and position tolerance of part processing, and it affects the quality of product, is concerning the serviceable life of equipment.Traditional axle class symmetry detects as shown in Figure 1, is that axle 2 is placed on the V1 shape piece, uses the gauge block 3 that equates with width of keyway to be placed in the keyway, measures with dial gauge 4.Or by its extend such as Fig. 2, shown in Figure 3, by orienting sleeve, main body V-shape base, rotate pressing plate, knurled nut, support bar, dial gauge and formed; Concrete operations are rotation knurled nuts 5 and rotate pressing plate 4, V-shape base is placed on the tested axle journal, go back to and rotate pressing plate 4, rotation knurled nut 5 fixes V-shape base 2, transfers the lever indicator gauge head again, and it is contacted with at the bottom of the keyway, precession trip bolt 3, orienting sleeve 1 is fastened on the main body V-shape base 2, makes it up and down play, can only rotate; Again the pointer of dial gauge is preset to zero-bit, turns round 180 in groove, have the numerical value of offset from zero to occur such as pointer, adjust the main body V-shape base, make dial gauge be shown as zero, expression 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 the side of keyway, the precession trip bolt 3 again, orienting sleeve 1 is only rotated, the difference of reading a of key slot side is measured in 2 positions of symmetry 180, then the symmetry error value in this cross section is f=axh d-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 the lathe in addition, the axle two ends are withstood with dial gauge with thimble and are placed on pulling measurement on the lathe saddle.More than measure the problem that exists step complexity in the time of to measure and to measure for smallclothes, because workpiece will move, unsettled, measurement data can not be directly perceived, checks for the major diameter key slot symmetry degree of shaft part, just require great effort very much, symmetry measurement cubing commonly used can not satisfy the measurement requirement thus.The product that the present invention relates to is the major diameter axial workpiece, and its diameter more than 400mm, is used for main equipment mostly, bears the larger occasion of torque ratio.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, key works to connect transmit force on the keyway, does not reach desirable design effect when making equipment work, and reduces serviceable life.
Summary of the invention: purpose of the present invention is exactly that a kind of slide calliper rule and method of operating for the check of major diameter key slot symmetry degree of shaft part 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, the slide calliper rule and the method for operating that are used for the check of major diameter key slot symmetry degree of shaft part, comprise blade, fixedly measuring jaw, digital display measuring head form, it is characterized in that: be respectively arranged with fixedly measuring jaw, movable measuring jaw on the blade, be respectively arranged with the digital display measuring head at the fixing two ends, the outside of measuring jaw, movable measuring jaw; Its method of operating is: after fixedly measuring jaw and movable measuring jaw are close to the keyway two sides, and locking activity measuring jaw; Adopt digital display zero setting adjustment block to be separately positioned on digital display measuring head and fixedly between the measuring jaw, carry out the zero setting adjustment between movable measuring jaw and the digital display measuring head; Mobile two ends digital display measuring head is to outer surface of workpiece respectively, and reading numerical values is A, numerical value B, and then (numerical value A-numerical value B)/2 are 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, and is easy to use, measuring accuracy is high, and measures reliably, has reduced labour intensity.The present invention has well solved symmetry commonly used and has measured cubing and can not satisfy problem to major diameter key slot symmetry degree of shaft part checking measurements requirement.
