[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] See Figure 1 As shown;

[0024] A utility model discloses a guide and positioning device for assembling a vehicle body mounting bracket, comprising: a positioning base 1.

[0025] The positioning seat 1 has a frame structure and a bearing platform on the top. The bearing platform is equipped with two replaceable positioning blocks, namely replaceable positioning block 2a and replaceable positioning block 2b. The top of replaceable positioning block 2a supports the positioning tube 3a through a groove and is used to be coaxial with the side plate of the part to be assembled. The top of replaceable positioning block 2b supports the positioning tube 3b through a groove and is used to be coaxial with the bushing of the part to be assembled. The groove limits the position of the center height of the positioning tube.

[0026] Among them, the bearing surface is fixedly connected to the guide positioning block 5 on both sides of the replaceable positioning block 2a and 2b. The guide positioning block 5 limits the replaceable positioning block 2a and 2b to ensure the left and right position of the center of the positioning tube.

[0027] When the guide positioning device is assembled, the positioning seats 1 are symmetrically arranged on both sides of the cover plate, and the replaceable positioning blocks 2a and 2b of the two positioning seats 1 jointly support the positioning round tubes 3a and 3b that penetrate the side plate.

[0028] Preferably, a sliding groove is provided on the positioning surface of the positioning seat 1, and the sliding groove is slidably connected to the slider at the bottom of the replaceable positioning blocks 2a and 2b, which makes assembly convenient;

[0029] Preferably, there are two positioning tubes 2a and 2b with different diameters. Specifically, the diameter of positioning tube 2a is larger than that of positioning tube 2b. When assembled, positioning tube 2a is used to position the coaxial shaft holes of side plate I 20 and side plate II 30, and positioning tube 2b is used to position the coaxial bushings 40 on the two side plates.

[0030] The upper surfaces of the replaceable positioning blocks 2a and 2b are formed with V-shaped grooves, which are used to self-center and position the round tube.

[0031] Preferably, the positioning base 1 has mounting holes at both the top and bottom, and the mounting holes are fixedly connected to the replaceable positioning blocks 2a, 2b and the base plate by bolts respectively.

[0032] In the above technical solution, the present invention provides a guiding and positioning device for assembling a vehicle body mounting bracket, the method of use of which is as follows:

[0033] See Figure 1As shown, the first step is to assemble side plate I 20, side plate II 30, and cover plate 10. First, install the replaceable positioning block 2a along the guide groove 4 and guide positioning block 5 on the positioning seat 1. After the replaceable positioning blocks 2a and 2b on both sides of the cover plate 10 are installed, place the cover plate 10 in the designated position. Pass the positioning tube 3a through side plate I 20 and side plate II 30, ensuring that the two round holes are coaxial. Place the cover plate 10 on side plate I 20 and side plate II 30 to complete the tack fixing of the cover plate 10 and the side plate. After natural cooling, remove the positioning tube 3a from the side and pull out the replaceable positioning blocks 2a on both sides from the outside.

[0034] See Figure 2 As shown, in the second step, the replaceable positioning block b is installed on the positioning seat 1 along the guide groove 4 and the guide positioning block 5. After the replaceable positioning blocks b on both sides are installed, the bushings 40 are placed in the shaft holes of the side plates respectively. The positioning tube 2b is passed through the two bushings 40 to ensure that the round holes of the two bushings 40 are coaxial. The position is adjusted to complete the tack fixing of the bushings 40. After cooling, the positioning tube 2b is pulled out from the side.

[0035] This guiding and positioning device for the assembly of car body hangers is simple to clamp and operate, requires low technical skills from operators, and provides accurate positioning, thereby improving the quality of the assembled workpiece.
