[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] Please refer to Figure 1-4The present invention provides a technical solution: a press-fitting device for a steering knuckle bushing of an automobile, comprising a press-fitting box 1 and a support plate 2, the support plate 2 being arranged inside the press-fitting box 1, a first support block 3 being fixedly installed in the middle of the upper outer surface of the support plate 2, a first telescopic rod sleeve 4 being fixedly installed on the upper portion of the first support block 3, a first movable rod 5 being inserted into the left and right sides of the first telescopic rod sleeve 4, a second support block 6 being fixedly installed on the front and rear outer surfaces of the two first movable rods 5 away from one end of the first telescopic rod sleeve 4, a threaded rod 7 being threaded through the outer surfaces of the two second support blocks 6, an annular clamping plate 8 being rotatably connected at the opposite ends of the two threaded rods 7. In this embodiment, when press-fitting automobile parts, the two threaded rods 7 on the left and right sides are rotated to drive the two annular clamping plates 8 on the left and right sides to move to a specified distance, and the parts to be press-fitted are fixed by the two annular clamping plates 8, and the two first movable rods 5 are retracted and extended at the same time to move the part where the steering knuckle bushing needs to be press-fitted to the center of the corresponding two press-fitting heads 16, thereby accurately positioning the universal joint position of the automobile parts and improving the press-fitting efficiency.

[0023] Two second telescopic rod sleeves 9 are fixedly installed on the inner surface of the bottom of the press-fitting box 1, and the two second telescopic rod sleeves 9 are symmetrically distributed. Two second movable rods 10 are fixedly installed on the outer surface of the bottom of the support plate 2, and the two second movable rods 10 are movably inserted in the two second telescopic rod sleeves 9 respectively. In this embodiment, when press-fitting automotive parts, the position of the second movable rod 10 inside the second telescopic rod sleeves 9 is adjusted according to the size of different parts, thereby driving the support plate 2 to move to the predetermined position, thereby realizing precise fixing of the parts position according to different parts sizes and improving the press-fitting efficiency.

[0024] Two hydraulic cylinders 15 are fixedly installed on the top outer surface of the press box 1. The mounting ends of the two hydraulic cylinders 15 are fixedly connected to the top outer surface of the press box 1. The output ends of the two hydraulic cylinders 15 are fixedly installed with press heads 16. The centers of the two press heads 16 correspond to the fixed blocks 17. In this embodiment, when press-fitting automobile parts, the pressure provided inside the hydraulic cylinders 15 drives the press heads 16 to work downward, thereby realizing the press-fitting of the steering knuckle bushing.

[0025] First sockets 14 are provided on the left and right sides of the first telescopic rod sleeve 4 and the outer surface of the first movable rod 5. There are several first sockets 14 on the outer surface of the first movable rod 5 and they are distributed in a linear array. The first sockets 14 corresponding to the outer surfaces of the first telescopic rod sleeve 4 and the first movable rod 5 are connected with first pins 13. In this embodiment, when it is necessary to move the first movable rod 5, the first pin 13 inside the first sockets 14 corresponding to the outer surfaces of the first movable rod 5 and the first telescopic rod sleeve 4 is pulled out to unlock the first movable rod 5 and the first telescopic rod sleeve 4, thereby moving the first movable rod 5. When it is necessary to fix the first movable rod 5, the first pin 13 is inserted into the first sockets 14 corresponding to the outer surfaces of the first movable rod 5 and the first telescopic rod sleeve 4 to lock the first movable rod 5 and the first telescopic rod sleeve 4, thereby fixing the first movable rod 5.

[0026] Two third support blocks 19 are fixedly installed on the top outer surface of the support plate 2. The two third support blocks 19 are symmetrically distributed about the first support block 3. The bottom outer surfaces of the two first movable rods 5 are both provided with slide grooves 18. The top outer surfaces of the two third support blocks 19 are both fixedly installed with fixed blocks 17. The ends of the two fixed blocks 17 away from the support plate 2 are respectively slidably connected to the inside of the two slide grooves 18. In this embodiment, when the first movable rod 5 is extended or retracted, the fixed block 17 slides in the slide groove 18, thereby ensuring that the fixed block 17, the third support block 19 and the pressing head 16 always maintain corresponding positions, thereby avoiding the hydraulic cylinder 15 driving the pressing head 16 to perform pressing work. The bottom of the first movable rod 5 is not supported by the corresponding fixed block 17, resulting in its bottom being hollow, causing the pressing head 16 to be damaged and deformed during pressing.

[0027] The outer surfaces of the two second telescopic rod sleeves 9 and the two second movable rods 10 are provided with second sockets 12. There are several second sockets 12 on the outer surface of the second movable rod 10 and they are distributed in a linear array. The second sockets 12 corresponding to the outer surfaces of the second telescopic rod sleeves 9 and the second movable rod 10 are connected with second pins 11. In this embodiment, when it is necessary to move the second movable rod 10, the second pin 11 inside the second sockets 12 corresponding to the outer surfaces of the second movable rod 10 and the second telescopic rod sleeves 9 is pulled out to unlock the second movable rod 10 and the second telescopic rod sleeves 9, thereby moving the second movable rod 10. When it is necessary to fix the second movable rod 10, the second pin 11 is inserted into the second sockets 12 corresponding to the outer surfaces of the second movable rod 10 and the second telescopic rod sleeves 9 to lock the second movable rod 10 and the second telescopic rod sleeves 9, thereby fixing the second movable rod 10.

[0028] Two insertion rods 20 are movably connected to the outer surface of the four second support blocks 6. The two insertion rods 20 are respectively arranged on the left and right sides of the threaded rod 7, and the two insertion rods 20 are symmetrically arranged. One end of the two insertion rods 20 close to the annular clamping plate 8 is fixedly connected to the annular clamping plate 8. In this embodiment, when the threaded rod 7 rotates, the insertion rod 20 moves in the corresponding second support block 6, avoiding the annular clamping plate 8 rotating with the rotation of the threaded rod 7 when the threaded rod 7 is rotated.

[0029] Working principle: When press-fitting automobile parts, the two threaded rods 7 on the left and right sides are rotated to drive the two annular clamping plates 8 on the left and right sides to move. After the two annular clamping plates 8 move to the predetermined position, the automobile parts are firmly fixed. At the same time, the first movable rod 5 is retracted to move the position where the steering knuckle bushing needs to be press-fitted inside the part to the center of the press-fitting head 16. At the same time, the fixed block 17 slides in the slide groove 18 to ensure that the fixed block 17, the third support block 19 and the press-fitting head 16 always maintain corresponding positions. When there are multiple steering knuckle bushings that need to be press-fitted inside a part, it is only necessary to continue moving the first movable rod 5 to align the position where the part needs to be press-fitted with the press-fitting head 16. During press-fitting, the hydraulic cylinder 15 works, and the hydraulic cylinder 15 drives the press-fitting head 16 to move. When the press-fitting head 16 contacts the position where the part needs to be press-fitted, the part is press-fitted, thereby realizing precise positioning and press-fitting of the position of the press-fitted steering knuckle bushing according to the needs of different parts, thereby improving the press-fitting efficiency.

[0030] When press-fitting automobile parts, the second pin 11 is removed according to the size of the press-fitted automobile parts as needed, the limit of the second movable rod 10 and the second telescopic rod sleeve 9 is released, and the position of the second movable rod 10 inside the second telescopic rod sleeve 9 is adjusted, thereby driving the support plate 2 to move to the predetermined position. After moving to the appropriate position, the second pin 11 is inserted into the corresponding second socket 12 to limit the position of the second telescopic rod sleeve 9 and the second movable rod 10, thereby achieving accurate fixing of the part position according to different part sizes and improving the press-fitting efficiency.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
