[0030] Please see Figure 1-5 This utility model provides a technical solution: a special pressing device for automotive parts, including a movable plate 1, a fixed plate 2 detachably connected to the top surface of the movable plate 1, one end of the fixed plate 2 being connected to the top surface of the movable plate 1 and the other end extending upward, a first bearing seat 3 being provided on the top surface of the movable plate 1, a first steering knuckle 5 being installed on the first bearing seat 3, a first connecting hole 15 being provided on the fixed plate 2 to match the shock absorber arm of the first steering knuckle 5, a second bearing seat 4 being provided on one side of the fixed plate 2, and a second steering knuckle 6 being installed on the second bearing seat 4;

[0031] Limiting posts are provided on the top surface of the movable plate 1 and one side of the fixed plate 2. The main pin holes of the first steering knuckle 5 and the second steering knuckle 6 are respectively fitted onto the two limiting posts.

[0032] It also includes two press-fitting assemblies 7, both of which can be detachably installed on one side of the fixing plate 2 and are used to press-fit and fix the first steering knuckle 5 and the second steering knuckle 6 respectively.

[0033] In this technical solution, both the first bearing housing 3 and the movable plate 1 are provided with matching first through holes, the first tie rod on the first steering knuckle 5 is slidably fitted in the first through hole, both the second bearing housing 4 and the fixed plate 2 are provided with matching second through holes, the second tie rod on the second steering knuckle 6 is slidably fitted in the second through hole; the movable plate 1 is also provided with a second connecting hole 16, and the shock absorber arm of the second steering knuckle 6 is matched with the second connecting hole 16.

[0034] During operation, firstly, the shock absorber arm of the first steering knuckle 5 must be passed through the first connecting hole 15, ensuring that the mounting surface of the first steering knuckle 5 corresponds to the first bearing seat 3. Simultaneously, the kingpin hole of the first steering knuckle 5 must be accurately aligned and fitted onto the limiting post on the top surface of the movable plate 1. Next, the shock absorber arm of the second steering knuckle 6 is passed through the second connecting hole 16, and the mounting surface of the second steering knuckle 6 must also correspond to the second bearing seat 4. Simultaneously, the kingpin hole of the second steering knuckle 6 is fitted onto the limiting post on the side of the fixed plate 2. Then, the two pressing components 7 are simultaneously activated. The two pressing components 7 work together to apply pressure to the first steering knuckle 5 and the second steering knuckle 6 respectively, achieving their pressing and fixing. This operation method allows both steering knuckles to be processed and fixed simultaneously, improving work efficiency.

[0035] In this process, the mounting surfaces of the first steering knuckle 5 and the second steering knuckle 6 are aligned and installed on the first bearing housing 3 and the second bearing housing 4, respectively. At the same time, two limiting posts are connected to the kingpin holes of the first steering knuckle 5 and the second steering knuckle 6, respectively, to limit the position of the two steering knuckles. Subsequently, the first steering knuckle 5 and the second steering knuckle 6 are pressed and fixed by two pressing components 7, so that the processing equipment can process the two steering knuckles at the same time, and there is no need to use multiple pressing devices for clamping, thereby effectively reducing production costs.

[0036] In this embodiment: the press assembly 7 includes a first hydraulic cylinder 71, a limiting block 72 and a movable block 73. The first hydraulic cylinder 71 consists of a first cylinder barrel and a first piston rod. One end of the first cylinder barrel is connected to one side of the limiting block 72. The first piston rod passes through the limiting block 72. The movable block 73 is connected to the end of the first piston rod away from the first cylinder barrel. A hinge 74 is also connected between the movable block 73 and the limiting block 72.

[0037] After the first steering knuckle 5 and the second steering knuckle 6 are installed, the first hydraulic cylinder 71 is activated, and hydraulic oil is pumped into the first cylinder barrel, pushing the first piston rod to move along the cylinder barrel axis. One end of the first piston rod passes through the limiting block 72, while the other end is connected to the movable block 73. As the first piston rod extends, it drives the movable block 73 to move together. A hinge 74 connects the movable block 73 and the limiting block 72. When pushed by the first piston rod, the movable block 73 can swing or fine-tune relative to the limiting block 72 in a controlled manner to adapt to different shape and position requirements during the press-fitting process. Simultaneously, the hinge 74 provides additional stability and support, ensuring the smooth progress of the press-fitting process. During the press-fitting process, as the first piston rod continues to extend, the movable block 73 gradually approaches and contacts the first steering knuckle 5 and the second steering knuckle 6 to be press-fitted, thereby press-fitting and fixing the first steering knuckle 5 and the second steering knuckle 6.

[0038] In this embodiment, the hinge 74 includes a fixed base 741, a first pin 742 and two connecting plates 743. The fixed base 741 is installed on one side of the limiting block 72. One end of the two connecting plates 743 is respectively installed on opposite sides of the fixed base 741, and the other end is respectively located on opposite sides of the movable block 73. The first pin 742 passes through and rotates in cooperation with the hinge.

[0039] The fixed seat 741 is installed on one side of the limiting block 72 as the supporting base of the hinge 74. One end of the two connecting plates 743 is installed on the opposite sides of the fixed seat 741, and the other end is located on the opposite sides of the movable block 73. The first pin 742 passes through the two connecting plates 743 and the movable block 73 and forms a rotational engagement with them, so that the movable block 73 can swing or be finely adjusted relative to the limiting block 72 within a certain range.

[0040] In this embodiment: the end of the first piston rod away from the first cylinder is connected to a locking block 8, and one end of the movable block 73 is provided with a locking groove 9. The locking block 8 is engaged in the locking groove 9 and is connected by a second pin 10.

[0041] When the first piston rod reciprocates along the first cylinder, the movable block 73 is driven to rotate on the hinge 74 by the locking block 8, so that the movable block 73 can swing or be finely adjusted relative to the limiting block 72 within a certain range.

[0042] In this embodiment, both the limiting block 72 and the fixing plate 2 are provided with multiple threaded holes 11, and each of the multiple threads is threaded with a threaded rod 12.

[0043] When the first hydraulic cylinder 71 malfunctions, the threaded rod 12 can be removed from the threaded hole 11, thereby removing the first hydraulic cylinder 71 from the fixing plate 2 for replacement.

[0044] In this embodiment, the top surface of the movable plate 1 is also provided with a first clamping component 13, which is used to clamp and fix the shock absorber arm of the first steering knuckle 5. The movable plate 1 is installed between the first bearing seat 3 and the first clamping component 13.

[0045] When the shock-absorbing arm of the first steering knuckle 5 extends through the first connecting hole 15 to the other side of the fixing plate 2, the shock-absorbing arm of the first steering knuckle 5 can be clamped and fixed by the first clamping assembly 13, thereby improving the machining accuracy.

[0046] In this embodiment: the first clamping assembly 13 includes a first support rod 131, a second hydraulic cylinder 132 and a first pressure plate 133. One end of the first support rod 131 is connected to the top surface of the movable plate 1, and the other end extends upward and contacts the bottom surface of the shock absorber arm of the first steering knuckle 5. The second hydraulic cylinder 132 consists of a second cylinder and a second piston rod. The bottom end of the second cylinder is connected to the bottom surface of the movable plate 1, and the second piston rod is slidably fitted inside the second cylinder. The first pressure plate 133 is installed at the end of the second piston rod away from the second cylinder, and one end of the first pressure plate 133 contacts the top surface of the shock absorber arm of the first steering knuckle 5.

[0047] When the shock absorber arm of the first steering knuckle 5 extends through the first connecting hole 15 to the other side of the fixing plate 2, the bottom surface of the shock absorber arm contacts the first support rod 131. Then, the second hydraulic cylinder 132 is activated, causing the second piston rod to change from its original extended state to a retracted state. During the retraction of the second piston rod, the first pressure plate 133 is driven to move downward until one end of the first pressure plate 133 contacts the top surface of the shock absorber arm of the first steering knuckle 5, thereby achieving the clamping and fixing of the shock absorber arm of the first steering knuckle 5.

[0048] In this embodiment, a second clamping component 14 is also provided on the top surface of the movable plate 1. The second clamping component 14 is used to clamp and fix the second steering knuckle 6. The second clamping component 14 and the second steering knuckle 6 are both located on the same side of the movable plate 1.

[0049] After the second steering knuckle 6 is installed, the shock absorber arm of the second steering knuckle 6 can be clamped and fixed by the first clamping assembly 13, thereby improving the machining accuracy.

[0050] In this embodiment: the second clamping assembly 14 includes a third hydraulic cylinder 141 and a second pressure plate 142. The third hydraulic cylinder 141 consists of a third cylinder barrel and a third piston rod. The bottom end of the third cylinder barrel is connected to the top surface of the movable plate 1. The third piston rod is slidably fitted inside the third cylinder barrel. The second pressure plate 142 is connected to the end of the third piston rod away from the third cylinder barrel. The second pressure plate 142 is arc-shaped.

[0051] In use, the third cylinder 141 is activated, causing the third piston rod to change from its original extended state to its retracted state. During the retraction of the third piston rod, the second pressure plate 142 is driven to move downward until the end of the second pressure plate 142 away from the third cylinder 141 contacts the top surface of the shock absorber arm of the second steering knuckle 6, thereby achieving the clamping and fixing of the shock absorber arm of the second steering knuckle 6.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
