[0027] Figure 1 and Figure 2 The structure of the press-fitting mechanism in the embodiment of the utility model is shown; Figure 1 and Figure 2 As shown, the press-fitting mechanism provided by the embodiment of the utility model includes:

[0028] Support seat 10;

[0029] The cylinder 20 is mounted on a bracket 30, and the bracket 30 includes a plurality of guide posts 33;

[0030] The guide plate 40 is slidably supported on the guide column 33, and the guide plate 40 is connected to a pressure head 44, and the pressure head 44 is arranged relative to the support seat 10;

[0031] The double pneumatic buttons 50 are electrically connected to the cylinder 20 . The cylinder 20 can operate when the double pneumatic buttons 50 are pressed simultaneously to drive the pressure head 44 to press down toward the support seat 10 .

[0032] The press-fitting mechanism of the utility model is provided with a support seat 10 for stably placing the workpiece to be press-fitted; the cylinder 20 is used to accurately control the downward pressing stroke; the guide plate 40 connected to the cylinder 20 and slidably supported on the guide column 33 is used; when the cylinder 20 drives the guide plate 40, the guide plate 40 drives the pressure head 44 set relative to the support seat 10 to press downward, thus stably and accurately achieving the press-fitting of the workpiece; further, through two pneumatic buttons 50 electrically connected to the cylinder 20, when the two pneumatic buttons 50 are pressed at the same time, the cylinder 20 operates to drive the pressure head 44 to press downward toward the support seat 10, thereby achieving the safety protection of the operator, avoiding the situation that the operator's hand is left in the press-fitting area and is accidentally injured due to a single trigger, and the cylinder 20 only operates during the period when the two pneumatic buttons 50 are pressed at the same time, and once the pneumatic button 50 is released, the cylinder 20 stops pressing downward, thus ensuring safety. The upward reset of the cylinder 20 can be achieved by another operating button (not specifically shown in the figure).

[0033] The press-fitting mechanism of the utility model can be applied to various automobile parts that need to be press-fitted by changing the support seat 10 and the pressing head 44; for example, the support seat 10 can be used to place the dust cover and cylinder of the shock absorber, and the cylinder is pressed down by the pressing head 44 to press the cylinder into the dust cover, thereby realizing the press-fitting of the dust cover and the cylinder.

[0034] In some embodiments, the press head 44 includes a hard outer contour and a soft inner layer attached to the hard outer contour. The hard outer contour is made of iron, for example, but not limited thereto; the soft inner layer is made of polyurethane, for example, but not limited thereto. The combination of the hard outer contour and the soft inner layer not only facilitates the assembly of the press head 44 and the guide plate 40, but also realizes a strong and effective press assembly of the workpiece, while buffering and protecting the workpiece to avoid damage to the workpiece.

[0035] In some embodiments, the guide posts 33 include two, the two ends of the guide plate 40 are slidably supported on the two guide posts 33, and the pressing head 44 is arranged in the middle of the guide plate 40. By the two ends of the guide plate 40 being slidably supported on the two guide posts 33, the stable guidance of the guide plate 40 and the simplified design of the structure are taken into consideration; by the pressing head 44 being arranged in the middle of the guide plate 40, the pressing head 44 is driven by the guide plate 40 to press down steadily, thereby realizing the stable press-fitting of the workpiece.

[0036] In some embodiments, the guide plate 40 is slidably supported on the guide column 33 via a linear bearing 46. The linear bearing 46 provides a stable and smooth sliding guide for the guide plate 40.

[0037] In some embodiments, the pressing head 44 is detachably connected to the guide plate 40. In this way, the pressing head 44 can be replaced with a suitable one according to the workpiece to be pressed, so that the pressing mechanism is suitable for pressing automobile parts of different types, models and sizes.

[0038] In some embodiments, the press-fitting mechanism further includes: a limit post 60, which is disposed on the downward pressing path of the guide plate 40. The limit post 60 limits the maximum downward pressing stroke of the guide plate 40, thereby preventing the workpiece from being crushed.

[0039] In some embodiments, the limiting posts 60 are located at both ends of the guide plate 40 and are arranged close to the guide posts 33. The limiting posts 60 are located at both ends of the guide plate 40 to achieve stable limiting of the guide plate 40; the limiting posts 60 are arranged close to the guide posts 33 to achieve that when the guide plate 40 moves downward along the guide posts 33 until it touches the limiting posts 60, it can stop pressing down immediately.

[0040] In some embodiments, the limiting column 60 includes a support column 62 and a limiting head 63, and a detachable gasket (not specifically shown in the figure) is arranged between the limiting head 63 and the support column 62. Through the detachable gasket, the height of the limiting column 60 can be adjusted as needed, so as to achieve accurate limiting of the downward stroke of the guide column 33.

[0041] In some embodiments, the bracket 30 further includes a mounting plate 34 mounted on the top of the guide column 33, and the cylinder 20 is mounted on the mounting plate 34. The mounting plate 34 allows the cylinder 20 to be stably mounted on the top of the guide column 33, so that the guide plate 40 can be pushed down along the guide column 33.

[0042] The utility model embodiment also provides a dust cover press-fitting device. Figure 3 The structure of the dust cover press-fitting equipment is shown in figure. Figures 1 to 3 As shown, the dust cover press-fitting device provided by the embodiment of the utility model comprises:

[0043] The press-fitting mechanism described in any of the above embodiments, wherein the support seat 10 is provided with a step wall 11 and a hollow cavity 12;

[0044] The shock absorber assembly includes a dust cover 82 disposed on the step wall 11 and a cylinder 83 embedded in the dust cover 82;

[0045] As the cylinder 20 is pressed downward, the cylinder barrel 83 can be pressed into the hollow cavity 12 by the pressing head 44 .

[0046] The dust cover pressing device adopts the above-mentioned pressing mechanism, and the dust cover 82 and cylinder 83 to be pressed are stably placed through the support seat 10; wherein the dust cover 82 is fixed on the step wall 11, and the cylinder 83 is embedded in the dust cover 82 and can be pressed into the hollow cavity 12. The cylinder 20 is used to accurately control the downward pressing stroke, and the guide plate 40 connected to the cylinder 20 and slidably supported on the guide column 33 is used. When the cylinder 20 drives the guide plate 40, the guide plate 40 drives the pressure head 44 set relative to the support seat 10 to press down the cylinder 83, and press the cylinder 83 into the dust cover 82, so as to stably and accurately press the dust cover 82 and the cylinder 83. Among them, the pressure head 44 can be formed into an inverted bowl shape, and when the pressure head 44 is pressed down, it can cover and buckle the top of the cylinder 83 to drive the cylinder 83 to be pressed down stably. Furthermore, through the two pneumatic buttons 50 electrically connected to the cylinder 20, when the two pneumatic buttons 50 are pressed at the same time, the cylinder 20 operates to drive the pressure head 44 to press down toward the support seat 10, thereby realizing the safety protection of the operator and avoiding the situation where the operator's hands remain in the pressing area and are accidentally injured due to a single trigger. The cylinder 20 only operates during the period when the two pneumatic buttons 50 are pressed at the same time. Once the pneumatic button 50 is released, the cylinder 20 stops pressing down, thus ensuring safety.

[0047] The dust cover press-fitting device of the utility model can be suitable for press-fitting dust covers 82 of different models and sizes by changing the support seat 10 and the pressing head 44.
