[0030] When the bushing 62 is press-fitted, firstly, the rear subframe body 6 is placed on the fixed support assembly 2 or the automatic alignment support assembly 3 of the press-fitting device, and then Figure 5 As shown, a body liner 61 is placed on a fixed support assembly 2 or an automatic alignment support assembly 3; then a bushing 62 is placed on the fixed support assembly 2 or the automatic alignment support assembly 3, so that a bushing 62 is placed above a body liner 61, and then Figure 6 As shown; finally, the pressing head of the pressing power equipment is used to act on each bushing 62, and the bushing 62 is pressed into the corresponding body liner 61 from top to bottom, and the press-fitting assembly of the subframe body bushing is completed. It can be seen that the press-fitting device of the utility model can perform press-fitting assembly of multiple bushings 62 at a time, which effectively improves the press-fitting efficiency; and, during the press-fitting assembly process, the automatic alignment bearing support assembly 3 can automatically adjust the upper and lower center axes of the bushing 62 and the upper and lower center axes of the body liner 61 to the same vertical straight line, and the bushing 62 and the body liner 61 are automatically aligned to ensure that the bushing 62 can be smoothly pressed into the body liner 61, thereby improving the press-fitting quality of the bushing 62.

[0031] Specifically, one rear sub-frame body 6 includes four body liners. In order to complete the press-fitting assembly of all bushings 62 in one rear sub-frame body 6 at one time, the number of groups on the fixed support assembly 2 and the automatic alignment support assembly 3 is 4. In order to improve the press-fitting quality of the bushing 62, the preferred solution is: the bottom plate 1 includes one group of fixed support assembly 2 and three groups of automatic alignment support assembly 3. The fixed support assembly 2 plays a certain positioning role to ensure the use effect of the automatic alignment support assembly 3. The arrangement of the fixed support assembly 2 and the automatic alignment support assembly 3 corresponds to the arrangement of the four body liners of the rear sub-frame body 6.

[0032] The function of the automatic alignment support assembly 3 is to automatically adjust the upper and lower center axes of the bushing 62 and the upper and lower center axes of the vehicle body liner 61 to the same vertical straight line, so that the bushing 62 and the vehicle body liner 61 are automatically aligned to ensure that the bushing 62 can be smoothly pressed into the vehicle body liner 61. In order to ensure the use effect of the automatic alignment support assembly 3, a preferred structure of the automatic alignment support assembly 3 of the utility model is: Figure 3 , Figure 4 As shown, the automatic alignment bearing support assembly 3 includes a vehicle body liner support sleeve 30, a press-fit support slider 31, a bushing support seat 32, an alignment slider 33, a left-right adjustment block 34 and a front-back adjustment block 35. An upper and lower slide groove 301 is arranged in the middle of the vehicle body liner support sleeve 30. The press-fit support slider 31 is matched and arranged in the upper and lower slide grooves 301, and the press-fit support slider 31 can move up and down along the upper and lower slide grooves 301. A liner placement cavity 302 is arranged between the side walls of the upper and lower slide grooves 301 and the press-fit support slider 31. The bushing support seat 32 is arranged on the press-fit support slider 31, and a bushing placement positioning pin 321 is arranged in the middle of the bushing support seat 32. The upper surface of the alignment slider 33 A front-to-back direction slide groove is provided, and a left-to-right direction slide groove 331 is provided on the lower surface of the alignment slider 33. The front-to-back direction slide groove and the left-to-right direction slide groove 331 are arranged perpendicular to each other. The front-to-back direction adjustment block 35 is connected and arranged in the front-to-back direction on the lower surface of the bottom of the vehicle body liner support sleeve 30. The front-to-back direction adjustment block 35 is matched and arranged in the front-to-back direction slide groove, and the front-to-back direction adjustment block 35 and the front-to-back direction slide groove can produce relative movement in the front-to-back direction; the left-to-right direction adjustment block 34 is connected and arranged on the base plate 1 in the left-to-right direction, and the left-to-right direction adjustment block 34 is matched and arranged in the left-to-right direction slide groove 331, and the left-to-right direction adjustment block 34 and the left-to-right direction slide groove 331 can produce relative movement in the left-to-right direction. The function of the liner placement cavity 302 is to enable the vehicle body liner 61 to be placed therein, so the liner placement cavity 302 has the same shape and structure as the lower half of the vehicle body liner 61, and the size of the liner placement cavity 302 is slightly larger than the size of the lower half of the vehicle body liner 61; and the upper and lower center axes of the liner placement cavity 30 and the upper and lower center axes of the bushing placement locating pin 321 are on the same vertical straight line.

[0033] The working principle of the automatic alignment bearing support assembly 3 is as follows: first, place the vehicle body liner 61 in the liner placement cavity 302, and then place the bushing 62 in the bushing placement positioning pin 321; then use the pressing head of the pressing power equipment to act on the bushing 62. If the upper and lower center axes of the bushing 62 and the upper and lower center axes of the vehicle body liner 61 are on the same vertical line, no adjustment is required, and the pressing head presses the bushing 62 directly into the vehicle body liner 61 from top to bottom. If the upper and lower center axes of the bushing 62 and the upper and lower center axes of the vehicle body liner 61 are not on the same vertical line, when the pressing head contacts the bushing 62, the pressing head applies a downward force to the bushing 62. Due to the upper and lower center axes of the bushing 62 and the upper and lower center axes of the vehicle body liner 61 The upper and lower center axes are not on the same vertical line, that is, the bushing 62 and the body liner 61 are in conflict with each other. When the pressure head applies a downward force to the bushing 62, the body liner 61 will also give the bushing 62 a reaction force. At this time, the bushing 62 and the automatic alignment support assembly 3 are a whole, so that the alignment slider 33 and the left and right adjustment block 34 produce relative movement in the left and right directions and / or the alignment slider 33 and the front and rear adjustment block 3 produce relative movement in the front and rear directions, until the upper and lower center axes of the bushing 62 and the upper and lower center axes of the body liner 61 are on the same vertical line, and the bushing 62 and the body liner 61 are automatically aligned to ensure that the bushing 62 can be smoothly pressed into the body liner 61.

[0034] In order to limit the distance that the alignment slider 33 moves in the left and right directions or the front and back directions and ensure the use effect of the alignment slider 33, Figure 4 As shown, the automatic alignment support assembly 3 of the utility model further includes a limiting sleeve 38, a limiting through hole 381 is arranged in the middle of the limiting sleeve 38, the limiting sleeve 38 is arranged on the bottom plate 1, and the vehicle body liner support sleeve 30 is arranged in the limiting through hole 381. Since the vehicle body liner support sleeve 30 is arranged in the limiting through hole 381, the moving distance of the vehicle body liner support sleeve 30 can only be within the range limited by the limiting through hole 381.

[0035] In order to further improve the use effect and overall connection strength of the automatic alignment support assembly 3, Figure 4 As shown, the limiting sleeve 38 includes a vertical side plate portion and a horizontal transverse plate portion, the horizontal transverse plate portion is vertically connected to the upper end of the limiting sleeve 38, and a circle of horizontal guide plates 303 are arranged on the circumference of the vehicle body liner support sleeve 30, and the upper surface of the horizontal guide plate 303 is in contact with the lower surface of the horizontal transverse plate portion.

[0036] The press-fitting support slider 31 moves downward along the upper and lower slide grooves 301 to bring the bushing 62 into the body liner 61. In order to improve the stability of the press-fitting support slider 31 moving downward and facilitate the removal of the rear subframe body 6 after the bushing 62 is press-fitted from the press-fitting device, Figure 4 As shown, the automatic alignment bearing support assembly 3 of the utility model also includes a return spring component 39, and the return spring component 39 includes a spring 391 and a spring locating pin 392. The press-fit support slider 31 is provided with a spring mounting groove with an opening at the lower end, and the upper half of the spring 391 is matched and arranged in the spring mounting groove, and the top of the spring 391 is connected to the bottom of the spring mounting groove; the lower end of the spring locating pin 392 is arranged on the base plate 1, and the upper end of the spring locating pin 392 passes through the alignment slider 33 and the bottom of the vehicle body liner support sleeve 30 in sequence, and the lower half of the spring 391 is sleeved on the spring locating pin 392. When the press-fitting support slider 31 moves downward, the spring 391 is compressed. When the bushing 62 is successfully pressed into the vehicle body liner 61, the pressure head of the press-fitting power equipment disappears. Under the action of the compression rebound force of the spring 391, the rear sub-frame vehicle body 6 on which the bushing 62 is pressed is lifted upward, and the various components of the bearing support assembly 3 are automatically aligned and returned to their initial positions, which also facilitates the removal of the rear sub-frame vehicle body 6 from the press-fitting device.

[0037] In order to further improve the press-fitting quality of the bushing 62 and improve the readiness of the body liner 61 to be placed in the position of the automatic alignment support assembly 3, Figure 3 , Figure 4 As shown, the automatic alignment support assembly 3 of the utility model further includes a body liner positioning sleeve 36, a body liner positioning through hole 361 is provided in the middle of the body liner positioning sleeve 36, the body liner positioning sleeve 36 is provided on the body liner support sleeve 30, and the body liner positioning through hole 361 is connected with the liner placement cavity 302, the upper and lower center axes of the body liner positioning through hole 361 are coaxial with the upper and lower center axes of the liner placement cavity 302, and the cross-sectional diameter of the body liner positioning through hole 361 is slightly larger than the cross-sectional diameter of the body liner 61. When the liner 62 is press-fitted, the body liner 61 is placed in the body liner positioning through hole 361 and the liner placement cavity 302 at the same time, and the body liner positioning through hole 361 and the liner placement cavity 302 play a positioning role together.

[0038] In order to prevent the bushing 62 from rotating during the press-fitting process, Figure 4 As shown, the automatic alignment support assembly 3 of the utility model further includes a bushing rotation prevention positioning pin 37, which is arranged on the circumference of the bushing placement positioning pin 321. A card slot is arranged at the lower end of the bushing 62, and the card slot is clamped on the bushing rotation positioning pin 37, thereby effectively preventing the bushing 62 from rotating during the press-fitting process.

[0039] The structure of the fixed support assembly 2 is similar to that of the automatic alignment support assembly 3, except that the fixed support assembly 2 does not have an automatic function, but has a support function. Compared with the automatic alignment support assembly 3, the fixed support assembly 2 does not include an alignment slider 33, a left-right direction adjustment block 34, and a front-back direction adjustment block 35, but includes all other components of the automatic alignment support assembly 3. The vehicle body liner support sleeve 30 in the fixed support assembly 2 is directly fixed to the base 1.
