Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a tooling for processing irregularly shaped parts in pairs. Background Technology

[0002] In the automotive manufacturing industry, the machining of irregularly shaped parts has always been one of the technical challenges, especially when these parts need to be machined in pairs, the technical challenges are even more significant. Irregularly shaped automotive parts, such as steering knuckles, connecting rods, and suspension arms, require highly specialized tooling to ensure their machining process is successful due to their unique shapes, complex structures, and stringent precision requirements.

[0003] As a key component of the automotive suspension system, the steering knuckle has a complex shape, requiring not only sufficient strength and rigidity but also stringent dimensional and positional accuracy. For steering knuckles machined in pairs, the shapes and dimensions of both sides must be completely identical to ensure stability and reliability after assembly. Therefore, designing a tooling system capable of precisely and efficiently machining irregularly shaped parts in pairs is particularly important.

[0004] Because automobile steering knuckles consist of a left steering knuckle and a right steering knuckle, which are used for mounting on the left and right front wheels respectively, the left and right steering knuckles have a symmetrical structure. However, during their machining, the left and right steering knuckles are usually machined separately, with only one part being machined at a time. This results in low work efficiency and also makes it difficult to meet the requirements of symmetrical and consistent assembly. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a tooling for processing irregularly shaped parts in pairs, so as to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution:

[0007] A pair of machining fixtures for irregularly shaped parts includes a base, with vertical plates connected to opposite ends of the top surface of the base. Multiple fixed seats are detachably connected to opposite sides of the vertical plates, the top surface of the base, and the bottom surface of the base. A positioning rod is connected to the center of the top surface of each fixed seat. A bearing seat is also provided on the top surface of the fixed seat. A first clamping component for fixing the steering knuckle body is also sleeved on the positioning rod. The bearing hole on the steering knuckle body is adapted to the bearing seat and is sleeved on the positioning rod.

[0008] Furthermore, the first clamping assembly includes multiple limiting blocks and nuts. The upper end of the positioning rod is a threaded rod. Multiple limiting blocks are sequentially sleeved on the positioning rod and located above the steering knuckle body. The nuts are threadedly engaged with the upper end of the threaded rod, and the bottom surface of the nuts contacts the top surface of the uppermost limiting hole.

[0009] Furthermore, multiple first threaded holes are provided on both sides of the vertical plate, and on the top and bottom surfaces of the base. Multiple second threaded holes that are compatible with the threaded holes are provided on the fixed base. Bolts are threadedly connected to the first threaded holes and the second threaded holes.

[0010] Furthermore, fixing rods are provided on both sides of the vertical plate and on the top and bottom surfaces of the base, and the fixing rods are adapted to the steering holes on the steering knuckle body.

[0011] Furthermore, limit rods are provided on the top surface of multiple bearing seats, and a limit hole adapted to the limit rod is opened on the bottom surface of one of the limit blocks.

[0012] Furthermore, it also includes a second clamping assembly, which is mounted on the top surface of the base and is used to clamp the shock absorber arm of the steering knuckle body mounted on the vertical plate.

[0013] Furthermore, the second clamping assembly includes a support base and a first limiting shaft. The support base is installed on the top surface of the base, and the first limiting shaft is installed on one side of the support base and is flush with the shock absorber arm of the steering knuckle body installed on the inner side of the vertical plate. A second limiting shaft is also installed on the vertical plate, and the opposite ends of the first limiting shaft and the second limiting shaft respectively contact the opposite sides of the shock absorber arm of the steering knuckle body.

[0014] The beneficial effects of this utility model are as follows:

[0015] This type of tooling for processing irregularly shaped parts in pairs allows for the simultaneous installation of three pairs of steering knuckle bodies via two fixed seats on the top surface of the base, two fixed seats on the bottom surface of the base, and fixed seats on the opposite sides of the two vertical plates. The steering knuckle bodies are gradually fixed by the first clamping, which facilitates the processing equipment to process the three pairs of steering knuckle bodies at the same time, thus improving work efficiency.

[0026] Please see Figure 1-3This utility model provides a technical solution: a tooling for processing irregularly shaped parts in pairs, including a base 1, with vertical plates 2 connected to both ends of the top surface of the base 1, and multiple fixing seats 3 detachably connected to both sides of the vertical plates 2, the top surface and the bottom surface of the base 1, and a positioning rod 4 connected to the center of the top surface of each fixing seat 3. A bearing seat 5 is also provided on the top surface of the fixing seat 3. A first clamping component 8 for fixing the steering knuckle body 6 is also sleeved on the positioning rod 4. The bearing hole 7 on the steering knuckle body 6 is adapted to the bearing seat 5 and is sleeved on the positioning rod 4.

[0027] In this technical solution, there are 2 fixing seats 3 on both the top and bottom surfaces of the base 1, and the two fixing seats 3 on the top surface of the base 1 and the two fixing seats 3 on the bottom surface of the base 1 are symmetrically distributed. There is 1 fixing seat 3 on each of the two vertical plates 2.

[0028] When machining the steering knuckle body 6, the first step is to precisely assemble the bearing holes 7 of the multiple steering knuckle bodies 6 onto the corresponding bearing seats 5 on the top surfaces of the multiple fixed seats 3, ensuring that they form an appropriate clearance fit. Next, the first clamping assembly 8 is installed around the positioning rod 4, and is brought into close contact with the top of the steering knuckle body 6. Simultaneously, the bottom of the steering knuckle body 6 contacts the fixed seats 3. Under the combined action of the base 1 and the first clamping assembly 8, the steering knuckle body 6 is clamped and fixed. The steering knuckle body 6 is divided into a left steering knuckle and a right steering knuckle. The fixed seats 3 on the opposite surfaces of the two vertical plates 2, the two fixed seats 3 on the top surface of the base 1, and the two fixed seats 3 on the bottom surface of the base 1 can respectively fix a set of left and right steering knuckles. Subsequently, the fixed steering knuckle body 6 is machined using machining equipment.

[0029] Among them, three pairs of steering knuckle bodies 6 can be installed simultaneously through the two fixed seats 3 on the top surface of the base 1, the two fixed seats 3 on the bottom surface of the base 1, and the fixed seats 3 on the opposite surfaces of the two vertical plates 2. The steering knuckle bodies 6 are gradually fixed by the first clamping, which makes it convenient for the processing equipment to process the three pairs of steering knuckle bodies 6 at the same time and improves the work efficiency.

[0030] In this embodiment: the first clamping assembly 8 includes multiple limiting blocks 81 and nuts. The upper end of the positioning rod 4 is a threaded rod. Multiple limiting blocks 81 are sequentially sleeved on the positioning rod 4 and located above the steering knuckle body 6. The nuts are threadedly engaged with the upper end of the threaded rod, and the bottom surface of the nuts contacts the top surface of the uppermost limiting hole 14.

[0031] After the bearing hole 7 of the steering knuckle body 6 is precisely assembled onto the corresponding bearing seat 5 on the top surface of the multiple fixed seats 3, multiple limiting blocks 81 are sequentially fitted onto the positioning rod 4. The thickness of the multiple limiting blocks 81 is different, and they can be selected for fitting as needed. Finally, the nut is threaded to the upper end of the positioning rod 4 so that the bottom surface of the nut contacts the top surface of the uppermost limiting hole 14, thereby fixing the limiting block 81 and the steering knuckle body 6.

[0032] In this embodiment: the vertical plate 2 has multiple first threaded holes 9 on both sides, the top surface and the bottom surface of the base 1, and the fixed seat 3 has multiple second threaded holes 10 that are adapted to the threaded holes. The first threaded holes 9 and the second threaded holes 10 are internally threaded with bolts.

[0033] Before fixing the steering knuckle body 6, the fixing seat 3 needs to be fixed first. Align the second threaded holes 10 on the multiple fixing seats 3 with the first threaded holes 9 on the opposite sides of the vertical plate 2 and the top and bottom surfaces of the base 1, and then fix the fixing seat 3 by passing the bolt thread through the first threaded hole 9 and the second threaded hole 10.

[0034] In this embodiment, fixing rods 11 are provided on both sides of the vertical plate 2 and on the top and bottom surfaces of the base 1. The fixing rods 11 are adapted to the steering holes 12 on the steering knuckle body 6.

[0035] During the installation of the steering knuckle body 6 on the opposite sides of the vertical plate 2 and the top and bottom surfaces of the base 1, the orientation of the steering knuckle body 6 needs to be fixed to facilitate the processing of the steering knuckle body 6 by the processing equipment. Before installing the steering knuckle body 6, the steering hole 12 on the steering knuckle body 6 is first fitted onto the fixing rod 11, and then the bearing hole 7 of the steering knuckle body 6 is precisely assembled onto the corresponding bearing seat 5 on the top surface of the multiple fixing seats 3. This facilitates the improvement of the processing accuracy of the steering knuckle body 6 and prevents the steering knuckle body 6 from shifting along the bearing seat 5 during the processing.

[0036] In this embodiment: a limit rod 13 is provided on the top surface of multiple bearing seats 5, and a limit hole 14 adapted to the limit rod 13 is opened on the bottom surface of one of the limit blocks 81.

[0037] After the bearing hole 7 of the steering knuckle body 6 is precisely assembled onto the corresponding bearing seat 5 on the top surface of the multiple fixed seats 3, the first limiting block 81 is sleeved on the positioning, and the limiting rod 13 on the top surface of the bearing seat 5 is inserted into the limiting hole 14 on the bottom surface of the limiting block 81 to prevent the limiting block 81 from shifting due to vibration during the processing, thereby further improving the processing accuracy of the steering knuckle body 6.

[0038] In this embodiment, a second clamping assembly 15 is also included. The second clamping assembly 15 is installed on the top surface of the base 1 and is used to clamp the shock absorber arm of the steering knuckle body 6 installed on the vertical plate 2.

[0039] The steering knuckle body 6 has a complex structure. The shock absorber arm of the steering knuckle body 6 faces the side. Therefore, the pair of steering knuckle bodies 6 installed on the vertical plate 2 have their sides facing upwards, which facilitates the processing of the shock absorber arm of the steering knuckle body 6. Therefore, during the processing, the shock absorber arm of the steering knuckle body 6 is clamped by the second clamping assembly 15 to improve the accuracy of the processing of the shock absorber arm.

[0040] In this embodiment: the second clamping assembly 15 includes a support base 151 and a first limiting shaft 152. The support base 151 is installed on the top surface of the base 1, and the first limiting shaft 152 is installed on one side of the support base 151 and is flush with the shock-absorbing arm of the steering knuckle body 6 installed on the inner side of the vertical plate 2. A second limiting shaft 153 is also installed on the vertical plate 2. The opposite ends of the first limiting shaft 152 and the second limiting shaft 153 respectively contact the opposite sides of the shock-absorbing arm of the steering knuckle body 6.

[0041] When the steering knuckle body 6 is installed on the fixed seat 3 on the vertical plate 2, the shock absorber arm is in the gap between the first limiting shaft 152 and the second limiting shaft 153, and the first limiting shaft 152 and the second limiting shaft 153 clamp the opposite sides of the shock absorber arm respectively, which further improves the machining accuracy of the shock absorber arm.

[0042] 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.
