A kind of motorcycle gear-shifting axle assembly cubing
Technical field
The utility model relates to a kind of cubing, especially a kind of motorcycle gear-shifting axle assembly cubing.
Background technology
The motorcycle gear-shifting axle assembly is very important mechanism in the motorcycle engine, the parts that are mated in engine have casing, shift drum etc., in assembling and use, the machining precision of its parts, gear shift arm (big arm) soldering angle, forearm opening angle etc. all there is very strict requirement, the detection difficulty of these projects is all bigger, detection method in the past is to measure with coelosphere, though also can reach high accuracy of detection, bother very much very time-consuming, effort.In addition, also often detect by some supplementary meanss, as shift axle assembly to be detected is put in the casing that is equipped with other related components such as shift drum by normal condition, see whether itself and other qualified related components satisfies matching requirements, this method efficient is low, degree of accuracy is not high, is easy to cause unstable product quality.
The utility model content
The purpose of this utility model provides a kind of easy to detect, time saving and energy saving, and the high motorcycle gear-shifting axle assembly cubing of accuracy of detection.
The technical solution of the utility model is: at least three root posts are fastenedly connected between upper and lower plate forms monitor station, upper plate is provided with positioning seat, positioning seat is provided with limiting plate, the width of limiting plate is consistent with the forearm A/F in the shift axle assembly, vertical fixing has register pin on the upper plate, be respectively arranged with coaxial axle sleeve on upper and lower plate, the diameter of register pin is consistent with the openings of sizes of big arm retracing spring two card bases in the shift axle assembly.
Positioning seat in the utility model and limiting plate are used for detecting the forearm A/F in the shift axle assembly, register pin is used for the main spring in the shift axle assembly is positioned, and coaxial axle sleeve is used for detecting the right alignment of Shift lever in the shift axle assembly and Shift lever being positioned on the upper and lower plate.During detection, Shift lever in the shift axle assembly is inserted, on the lower plate in the coaxial axle sleeve, big arm is placed on the upper plate, and the forearm in the shift axle assembly is placed on the positioning seat, two card bases of main spring are stuck on the register pin in the shift axle assembly, allow the outer end of limiting plate stretch in the opening of forearm in the shift axle assembly, see whether forearm is close to the positioning seat upper surface, smooth, whether the gap of limiting plate both sides is consistent, because positioning seat, limiting plate, therefore relative position between register pin and the axle sleeve and highly all simulated the actual installation state of shift axle assembly in motorcycle engine can comprehensively judge the Shift lever diameter of axle, big arm soldering angle; the centre distance of forearm and big arm; whether forearm A/F etc. meets the requirements.
The beneficial effects of the utility model are: make the detection of motorcycle gear-shifting axle assembly accurate more, quick, easy to operate, and can the strict quality of controlling product.

Detected motorcycle gear-shifting axle assembly is represented in two-dot chain line among the figure.
Embodiment
As Fig. 1, shown in Figure 2, the utility model is by upper plate 1, lower plate 2, column 3, nut 4, socket head cap screw 5, positioning seat 6, limiting plate 7, straight pin 8, register pin 9, axle sleeve 10, axle sleeve 11, socket head cap screw 12 and standard axle 13 are formed, four root posts 3 are fastenedly connected last, lower plate 1, form monitor station between 2, upper plate 1 is provided with positioning seat 6, positioning seat 6 is provided with limiting plate 7, the width of limiting plate 7 is consistent with the forearm A/F in the shift axle assembly, vertical fixing has register pin 9 on the upper plate 1, last, lower plate 1, be respectively arranged with coaxial axle sleeve 10 on 2,11, the diameter of register pin 9 is consistent with the openings of sizes of big arm retracing spring two card bases in the shift axle assembly.
Shown in Fig. 1 on upper plate 1 also vertical fixing standard axle 13 is arranged, the centre distance in two holes is consistent on the control arm of standard axle 13 axle center in the distance in axle sleeve 10,11 axle center and the shift axle assembly, has the bayonet socket 13a that the end with motion arm is complementary on the standard axle 13.Thereby also can detect the centre distance of Shift lever in the angle of control arm and control arm and the shift axle assembly simultaneously.
Also can find out from Fig. 2: described positioning seat 6 is fixed on the upper plate 1 by straight pin 8 and socket head cap screw 5, and the hole 7a of adjustment is arranged on the limiting plate 7, and socket head cap screw 12 passes this adjustment hole 7a limiting plate 7 is fixed on the positioning seat 6.Two straight pins 8 that are on the diagonal line are used for positioning seat 6 accurately is positioned on the upper plate 1.Limiting plate 7 can carry out position adjustments by adjusting hole 7a, to adapt to the detection needs of different model product.
During detection, Shift lever in the shift axle assembly 14 is inserted, lower plate 1, coaxial axle sleeve 10 on 2, in 11, big arm 15 is placed on the upper plate 1, and the forearm in the shift axle assembly 16 is placed on the positioning seat 6, two card bases of main spring 17 are stuck on the register pin 9 in the shift axle assembly, allow the outer end of limiting plate 7 stretch in the opening of forearm 16 in the shift axle assembly, see whether forearm 16 is close to positioning seat 6 upper surfaces, smooth, whether the gap of limiting plate 7 both sides is consistent, because positioning seat 6, limiting plate 7, register pin 9 and axle sleeve 10, therefore relative position between 11 and highly all simulated the actual installation state of shift axle assembly in motorcycle engine can comprehensively judge Shift lever 14 diameters of axle, big arm 15 soldering angles; 15 centre distance of forearm 16 and big arm; whether forearm 16 A/Fs etc. meet the requirements.But standard axle 13 is Option stages, when in the product motion arm 18 being arranged, standard axle 13 is installed on the upper plate 1, during detection, allow an end of motion arm 18 link to each other with Shift lever 14, see whether the other end can insert in the hole of standard axle 13 upper surfaces, and insert the state in this hole, can judge in view of the above whether the centre distance of Shift lever 14 in the angle of control arm 18 and control arm 18 and the shift axle assembly meets the demands.
