[0052] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0053] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0054] In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the specification of the present invention may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0055] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings connoted by each term.

[0056] like Figures 1 to 5 As shown, the present invention discloses a flexible profilometer measurement fixture for steering knuckles and wheel brackets, comprising a base 10, a support 20, a rotating assembly, a first angle positioning assembly, a second angle positioning assembly, a connecting plate 30, and a clamping assembly. The support 20 is fixed to the base 10 (e.g., via bolts), and the rotating assembly is mounted on the upper end of the support 20.

[0057] The first angular positioning assembly is mounted on the rotating assembly, and the second angular positioning assembly is connected to the first angular positioning assembly via a bracket 40, with the two being perpendicular to each other. A connecting plate 30 is mounted on the side of the second angular positioning assembly, and the clamping assembly is connected to the connecting plate to clamp the steering knuckle or wheel bracket.

[0058] Preferably, the rotating assembly includes a rotating base 50 and a rotating shaft 51. The rotating base 50 is mounted on the support 20, and the rotating shaft 51 is mounted on the rotating base 50, so that the rotating base 50 and the rotating shaft 51 rotate around the X-axis in the corresponding pitch direction.

[0059] The first angle positioning assembly may preferably include a first angle positioning plate 60 and a first angle plate 61. The first angle positioning plate 60 is mounted on the rotating shaft 51 and rotates around the rotating shaft 51. The first angle plate 60 is mounted on the first angle positioning plate 60 and rotates 360° around the first angle positioning plate 60.

[0060] Furthermore, the bracket 40 may preferably be an L-shaped bracket.

[0061] The second angle positioning assembly may preferably include a second angle positioning plate 70 and a second angle plate 71, wherein the second angle positioning plate 70 is connected to the vertical end surface of the L-shaped bracket, and the first angle plate 60 is connected to the horizontal end surface of the L-shaped bracket (for example, the L-shaped bracket is disposed on the side of the second angle plate 71, and the two are assembled into one body by bolts). The second angle plate 71 is mounted on the second angle positioning plate 70 and rotates 360 degrees around the second angle positioning plate 70.

[0062] In addition, a plurality of upwardly extending positioning posts 80 are provided on the outer peripheral end surfaces of the first angle positioning plate 60 and the second angle positioning plate 70 , and a hook portion 81 is provided on the upper portion of the positioning posts 80 for fixing the corresponding first angle plate 61 and second angle plate 71 .

[0063] Meanwhile, scales are engraved on the discs of the first angle plate 61 and the second angle plate 71. The diameters of the first angle positioning plate 60 and the first angle plate 61 are preferably set to 130 mm, and the diameters of the second angle positioning plate 70 and the second angle plate 71 are preferably set to 100 mm.

[0064] The clamping assembly includes a first clamping handle 90, a clamping plate 91, and a positioning pin 92. A plurality of mounting holes 31 are provided on the connecting plate 30. The positioning pins 92 are installed in the mounting holes 31 to position the steering knuckle or wheel bracket. The steering knuckle or wheel bracket is positioned on the positioning pin 92 through the brake caliper hole, and then the first clamping handle 90 presses the clamping plate 91 against the steering knuckle or wheel bracket (e.g. Figure 1 shown).

[0065] In addition, at least one second pressing handle 100 is mounted on the base 10 for fixing the profilometer flexible measuring fixture to the profilometer table.

[0066] According to the above structural description, the combination of the swivel base 50 and the rotating shaft 51, as well as the second angle positioning plate 70 and the second angle plate 71, on the flexible measuring fixture of the profilometer of the present invention can achieve rotation about the X and Y axes. The first angle positioning plate 60 and the first angle plate 61 can achieve rotation about the Z axis, thus flexibly providing various postures for the workpiece.

[0067] The swivel base 50 and the shaft 51 correspond to pitch rotation about the X-axis, while the first angle positioning plate 60 and the mechanisms attached thereto can also rotate about the shaft 51. Therefore, the shaft 51 and swivel base 50 must cooperate well and rotate smoothly. The first angle plate 61 and the mechanisms attached thereto can rotate 360° around the first angle positioning plate 60. The disc of the first angle plate 61 is engraved with a dense scale, allowing for precise rotation about the Z-axis and recording the corresponding scale parameters.

[0068] The first angle plate 61 is connected to the second angle positioning plate 71 through an L-shaped bracket. The second angle plate 71 and the mechanism thereon can rotate 360° around the second angle positioning plate 70. The disc of the second angle plate 71 is engraved with denser scales, and can perform more precise rotational motion around the Y-axis, and can record corresponding scale parameters.

[0069] The positioning pins 92 on the connecting plate 30 can be adjusted according to the spacing of the brake caliper holes of each vehicle model, so that they can flexibly adapt to the positioning of brake caliper holes of various different spacings.

[0070] In addition, after the workpiece is initially measured on the profilometer fixture, the corresponding rotation parameters of the angle plate can be recorded, making it easier to quickly find the optimal posture for the workpiece when measuring again.

[0071] The combined structure of the first angle positioning plate 60 and the first angle plate 61 is as follows: Figure 2 and Figure 3 As shown, the two form a smoothly rotating slide, and four protective blocks (i.e., positioning columns 80) are installed around them to ensure that the two are solid and reliable in both static or rotating states. There is an adjustable tightening handle 82 on the side, which can be used to tighten the rotating device after rotating to the desired scale position.

[0072] Similarly, the second angle positioning plate 70 and the second angle plate 71 are combined into a structure as shown in FIG. Figure 4 and Figure 5 As shown, the two also form a smoothly rotating slide.

[0073] At the same time, four protective blocks (i.e. positioning columns 80) are installed around to ensure that both are solid and reliable in static or rotating states. There is an adjustable tightening handle 82 on the side, which can be used to tighten the rotating device after rotating to the required scale position.

[0074] Considering the counterweight and stability of the entire device, the diameter of the combined structure of the first angle positioning plate 60 and the first angle plate 61 is relatively large, and can be preferably φ130 mm.

[0075] The diameter of the combined structure of the second angle positioning plate 70 and the second angle plate 71 is relatively small, and may preferably be φ100 mm.

[0076] In summary, the flexible profilometer measuring fixture for steering knuckles and wheel brackets of the present invention has the following advantages:

[0077] 1. It can be truly applicable to the steering knuckles and wheel brackets of multiple models, and is highly flexible and easy to use.

[0078] 2. Compared with the profilometer measurement fixture that can only be used for a single car model, this flexible fixture can greatly reduce the total cost investment.

[0079] 3. At the same time, it saves space. The more car models there are, the more obvious the effect of reducing costs and saving space will be.
