The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1; The structural representation of the kingpin bore drill jig 100 that it provides for the utility model preferred embodiments; Kingpin bore drill jig 100 is used to locate front axle 200 and carries out kingpin bore processing in the gradation of the two ends of front axle 200, and front axle 200 comprises two front axle fists 201 and the connector 203 that connects two front axle fists 201.
Kingpin bore drill jig 100 comprises clamp base 10, rotary body 20, pole bracket 30 and bushing plate 40.Rotary body 20 rotates and is arranged on the clamp base 10; Pole bracket 30 is fixed on a side of clamp base 10; Bushing plate 40 is slidingly arranged on the pole bracket 30 and can does the rectilinear motion perpendicular to clamp base 10 along pole bracket 30; Rotary body 20 clamps connector 203, and bushing plate 40 is in the horizontal to front axle fist 201 location and completion kingpin bore processing on front axle fist 201.
The center of rotary body 20 is provided with rotating shaft 21, and is provided with the 21 axial symmetry settings of 23, two convexities of two convexities, 23 relative rotation axis with the obedient mutually side of clamp base 10 on the rotary body 20.Also be provided with at least one clamping device that is used to clamp connector 203 (figure does not show) on the rotary body 20.
Kingpin bore drill jig 100 mainly utilizes:
1, geometrical relationship: the relation according to two kingpin bore parallel axes of front axle 200, can find a rotation, when the rotary body that is fixed with front axle 200 20 during around this axis turnback, two kingpin bores overlap, and realize combining process;
2, theory of mechanics: design rotating shaft 21 at rotation axis measurement, and design rectangle stopper slot 122, make rotary body 20 have only the Rotate 180 degree, could get into stopper slot 122 once more, and two kingpin bores are at same position at two ends;
3, mechanical designing technique: slide in said guide rail through bushing plate 40, when guaranteeing that front axle 200 length overalls fluctuate in the reasonable scope, guarantee that kingpin bore termination wall thickness is constant, length overall is qualified.
The operating process of kingpin bore drill jig 100 is following: front axle 200 is put into clamping on the rotary body 20, and dog screw when pushing bushing plate 40 to front axle 200 (locating part 43) is near front axle fist 201, and at this moment locking rotary body 20 accomplishes end kingpin bore processing; Unclamp rotation 20 and turnback, lock rotary body 20 again, dog screw is accomplished the processing of other end kingpin bore near front axle fist 201 when pushing bushing plate 40 to front axle 200.
