The invention will be further described with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 to 3, the anti-loose shoulder assembling bolt according to the present embodiment includes:
the bolt comprises a bolt body 10, wherein the bolt body 10 comprises a stud part 11 with external threads, a rotating head 12 is arranged on the stud part 11, an annular shoulder plate 13 is arranged between the rotating head 12 and the stud part 11, and a plurality of locking grooves 14 distributed in an annular array manner around the axis of the annular shoulder plate 13 are formed in the end surface, facing the stud part 11, of the annular shoulder plate 13;
the non-standard washer 20 is provided with a screw hole 21 for the stud part 11 to pass through, the non-standard washer 20 is provided with a plurality of square punched holes 22 distributed around the axis of the screw hole 21 in an annular array, each square punched hole 22 is provided with an extending side 23, each square punched hole 22 is provided with a buffer arc-shaped plate 24 with an upward raised middle part and two downward extending ends, and one end of each buffer arc-shaped plate 24 is connected with the extending side 23.
Furthermore, the locking groove 14 is semi-cylindrical, the length extending direction of the locking groove is perpendicular to the axial direction of the bolt main body 10, and the locking groove 14 can be formed by punching or extrusion molding through a protruding die matched with the locking groove 14, so that the locking groove 14 can be formed conveniently.
Furthermore, the two ends of the locking groove 14 and the end surface of the annular shoulder plate 13 are in arc transition, so that the connection part is prevented from being in straight line bending transition, and the connection part is stressed intensively to be broken.
Further, the number of the locking grooves 14 is 8, and the locking grooves are distributed in an annular array at equal intervals; the number of the square punched holes 22 is 4, and the square punched holes are distributed in an annular array at equal intervals. The quantity is set, so that the buffering arc-shaped plate 24 on the square punched hole 22 can be embedded into the locking groove 14 after rotating by 45 degrees in the circumferential direction, and clamping is convenient to realize.
Further, buffering arc 24 and nonstandard packing ring 20 set up as an organic whole, the stamping forming of being convenient for it is convenient to make.
