Embodiment
The utility model is described in further detail below by embodiment:
See also Fig. 1, it is the scheme of installation that the utility model highi degree of accuracy repeats installing and locating mechanism one better embodiment.See also Fig. 1, described highi degree of accuracy repeats installing and locating mechanism and is made up of a location screw 1 and elastic expansion sleeve 2, described elastic expansion sleeve 2 be enclosed within on the positioning screwn 1 and pass anchor clamps positioning hole 13 after be fixed on the product orientation hole 14, and described positioning screwn 1 passes elastic expansion sleeve 2 and closely links to each other with product tapped hole 15, thereby realizes being fastenedly connected between product 11 and the anchor clamps 12.
Please consult Fig. 2 simultaneously, it is the structural representation of positioning screwn among Fig. 1.Described positioning screwn 1 from left to right is followed successively by screw head 3, conical screw 4, straight screw rod 5 and threaded termination 6.Wherein said conical screw 4 links to each other the diameter of part greater than its diameter and termination 6 diameters with straight screw rod 5 connecting parts with screw head 3, described straight screw rod 5 diameters are less than conical screw 4 join with it diameter and the termination external thread diameter at .0 place.
See also Fig. 3, it is the structural representation of elastic expansion sleeve 2 among Fig. 1.The sleeve that described elastic expansion sleeve 2 connects about being, its left end is for leading mouth 7 with conical screw 4 corresponding tapers, and the right-hand member inwall is provided with the internal thread 8 that is complementary with positioning screwn termination 6 screw threads.Described elastic expansion sleeve taper is led and is the sleeve of diameter greater than positioning screwn 1 termination external thread diameter between mouth 7 and the right-hand member internal thread 8.And described elastic expansion sleeve 2 has four and groovings 9 that space consistent vertical with the left side from left to right, and described grooving 9 degree of depth are less than the left and right sides length of elastic expansion sleeve 2.In addition, elastic expansion sleeve 2 outside of closing on right-hand member has an annular groove 10.
When the utility model highi degree of accuracy repeats installing and locating mechanism installing and locating, described elastic expansion sleeve 2 is enclosed within on the positioning screwn 1, and pass anchor clamps positioning hole 13 and be fixed on the outer product orientation hole 14 of product tapped hole 15, wherein, described anchor clamps positioning hole 13 is consistent and coaxial with the diameter in product orientation hole 14, and has the internal thread that is complementary with positioning screwn termination 6 screw threads in the described product tapped hole 15.The termination 6 of described positioning screwn 1 is passed elastic expansion sleeve 2 and is closely linked to each other with product tapped hole 15, simultaneously, mouth 7 is led in the taper of the conical screw 4 extruding elastic expansion sleeves 2 of positioning screwn 1, make it pass through four groovings 9 and groove 10 to anchor clamps positioning hole 13 and 14 extruding of product orientation hole, eliminate the gap between itself and anchor clamps positioning hole 13 and the product orientation hole 14, thereby reduce positioning error.
