detailed description

The technical solutions of the present utility model will be clearly and completely described below through specific embodiments in conjunction with the accompanying drawings.

As shown in Figures 1 to 7, an air spring positioning device includes an upper mold 1, a lower mold 2 and an adjusting rod 3, and the adjusting rod 3 is a screw rod.

The upper mold 1 includes at least two upper positioning plates 11 . The shape of the upper positioning plate 11 is I-shaped in section, and the central position of the middle crossbar of the upper positioning plate 11 of the I-shaped is provided with a positioning groove 111, and the shape of the positioning groove 111 is a square. The positioning groove 111 of one upper positioning plate 11 is arranged on the upper end surface, and the positioning groove 111 of the other upper positioning plate 11 is arranged on the lower end surface, and the two are buckled and spliced into a cross structure. Threaded holes 112 are provided on both sides of the positioning groove 111 on the cross bar, and the threaded holes 112 are used for threading and threading of the screw rod.

The lower mold 2 includes at least two lower positioning plates 21 . The shape of the lower positioning plate 21 is I-shaped in section, and the central position of the middle cross bar of the lower positioning plate 21 of the I-shaped is provided with a positioning groove 111, and the shape of the positioning groove 111 is a square. The positioning groove 111 of one lower positioning plate 21 is arranged on the upper end surface; the positioning groove 111 of the other lower positioning plate 21 is arranged on the lower end surface, and the two are snapped together to form a cross structure. Threaded holes 112 are provided on both sides of the positioning groove 111 on the cross bar, and the threaded holes 112 are used for threading and screwing of the screw rods. The upper end surface of one lower positioning plate 21 and the lower end surface of the other are respectively provided with nuts 211 corresponding to the threaded holes 112 , and the nuts 211 and the lower positioning plate 21 are integrally formed. The inner diameter of the thread of the nut 211 is equal to the inner diameter of the threaded hole 112 .

Optionally, the ends of the upper positioning plate 11 and the lower positioning plate 21 in the axial direction are provided with arc surfaces that fit inside the air spring (that is, the outer end of the I-shaped positioning plate is cut into an arc shape, and the arc surface The size should match the arc size of the product, so as to ensure that the inner arc of the air spring does not deform). In the utility model, the center angles corresponding to all the arc surfaces are equal, and the centers of the arc surfaces on the same horizontal plane are at the same point.

Optionally, the number of screws is equal to the number of screw holes 112 of the upper die 1 (the screw holes 112 of the upper die 1 and the lower die 2 are set in one-to-one correspondence, therefore, the number of screw holes 112 of the upper die 1 and the lower die 2 is equal).

How to use: Firstly, cross-join the positioning plate of the upper mold and the lower mold; secondly, correct the threaded hole of the positioning plate of the upper mold and the threaded hole of the positioning plate of the lower mold so that they are in the same vertical direction; then, place the The screw goes through one of the threaded holes of the positioning plate of the upper mold (it can also be penetrated from the positioning plate of the lower mold), and passes through the corresponding threaded hole of the positioning plate of the lower mold; then, thread the remaining screws into the remaining threads in turn In the hole, when all connections are completed, the assembly of the entire positioning device is realized; finally, the connection length between each screw rod and the positioning plate is adjusted to keep the upper mold and the lower mold horizontal. To adjust the distance between the upper die and the lower die, the distance between each screw rod needs to be adjusted. Note: After the adjustment is completed, it must be ensured that the upper mold and the lower mold are kept level.

The air spring positioning device of the utility model is composed of four I-shaped positioning plates and four screw rods. Therefore, the orthographic projection surface of the positioning device is in the shape of "#" after the splicing is completed.
