[0042] Embodiment 1:

[0043] A processing fixture for an automotive wheel bracket, as Figures 1-6 shown, is applied to the clamping during the processing of an automotive wheel bracket workpiece 2. The processing fixture for an automotive wheel bracket includes a base 1, a main support assembly, an inclined support assembly, a limiting assembly, and a pressing assembly:

[0044] A plurality of groups of channels are provided inside the base 1. The channels can supply gas or oil, and are set according to requirements. For example, the arc-shaped blowing member 4 is communicated with the cylinder through the channels; the main support assembly for supporting the position of the automotive wheel bracket workpiece 2 is installed on the base 1; the inclined support assembly for supporting the bottom inclined surface of the automotive wheel bracket workpiece 2 is installed on the base 1; the limiting assembly for laterally limiting the position of the automotive wheel bracket workpiece 2 is installed on the base 1; the pressing assembly for limiting the position of the automotive wheel bracket workpiece 2 from above is installed at a position close to the outside on the base 1; wherein, the main support assembly, the inclined support assembly, and the pressing assembly are communicated with the channels at corresponding positions.

[0045] During use, the main support assembly and the pressing assembly cooperate to limit the up and down direction of the automotive wheel bracket workpiece 2, and the limiting assembly limits the side direction of the automotive wheel bracket workpiece 2, realizing the stable clamping of the automotive wheel bracket workpiece 2. Cooperating with the inclined support assembly, the automotive wheel bracket workpiece 2 is further limited in all directions, thereby further improving the processing accuracy of the automotive wheel bracket workpiece 2.

[0046] Embodiment 2:

[0047] On the basis of Embodiment 1, as Figures 1-4 shown, the structure of the main support assembly in this embodiment is shown.

[0048] The main support assembly includes a positioning reference seat 3 and auxiliary parts:

[0049] The number of the positioning reference seats 3 is four groups. The positioning reference seats 3 are installed on the base 1 and are communicated with the channels. The telescopic ends of the positioning reference seats 3 are attached to the lower end surface of the automotive wheel bracket workpiece 2;

[0050] The positioning reference seat 3 can stably support the lower end surface of the automotive wheel bracket workpiece 2.

[0051] The positioning reference seat 3 ensures the unity of the fixture reference and the workpiece reference, maintains a stable coordinate relationship with the machine tool, and eliminates the positioning error caused by inconsistent references.

[0052] The number of auxiliary parts is three groups, and the auxiliary parts are arranged on one side of the positioning reference seat 3.

[0053] The auxiliary part adopts an arc-shaped air blowing part 4. The arc-shaped air blowing part 4 is fixedly installed on the base 1, and the arc-shaped air blowing part 4 is communicated with the channel, and is used to blow away the sundries on the upper end of the positioning reference seat 3.

[0054] Before the automobile wheel bracket workpiece is placed on the processing fixture, the channel supplies air and the arc-shaped air blowing part 4 blows air, which can directly blow away the sundries on the upper end of the positioning reference seat 3.

[0055] The present utility model discloses a processing fixture for an automobile wheel bracket, which records a main support assembly. The main support assembly includes a positioning reference seat 3 and an auxiliary part. The auxiliary part adopts an arc-shaped air blowing part 4, and the arc-shaped air blowing part 4 is communicated with the channel.

[0056] Embodiment 3:

[0057] On the basis of Embodiment 2, as Figures 1-7 shown, this embodiment is other structures on the base 1.

[0058] The limiting component includes a fixing part 5 and a close-fitting part 6:

[0059] The number of fixing parts 5 is several groups. The fixing parts 5 are fixedly installed on the base 1 near the outer side through bolts and are arranged in multiple directions;

[0060] The number of close-fitting parts 6 is several groups. The close-fitting parts 6 are fixedly installed on the upper end surface of the base 1. The side end surface of the close-fitting part 6 is in contact with the side end surface of the automobile wheel bracket workpiece 2. The end surface of the close-fitting part 6 is arc-shaped and is in full contact with the side end surface of the automobile wheel bracket workpiece 2, so the fixing effect is better.

[0061] One group of the close-fitting parts 6 adopts an angular auxiliary positioning part, and the angular auxiliary positioning part is in contact with one of the corners of the automobile wheel bracket workpiece 2, which can further limit the position of the automobile wheel bracket workpiece 2.

[0062] The limiting component includes a telescopic cylinder component 7. The main body part of the telescopic cylinder component 7 is fixedly installed on the upper end surface of the base 1. The telescopic end of the telescopic cylinder component 7 is in contact with the lower end surface of the base 1. When the telescopic cylinder component 7 extends, it contacts the lower end surface of the automobile wheel bracket workpiece, playing a role in supporting the automobile wheel bracket workpiece.

[0063] The present utility model discloses a processing fixture for an automotive wheel bracket, which records a limiting component and an inclined support component. The inclined support component provides an inclined support. The tight-fitting piece 6 in the limiting component directly fits against the side end face of the automotive wheel bracket workpiece, and together with the angular auxiliary positioning piece, it can further improve the stability of the automotive wheel bracket workpiece, thus facilitating the precise processing of the automotive wheel bracket workpiece.

The four groups of rotary pressing cylinders 8 are installed at positions close to the four corners on the base 1, and the rotary pressing cylinders 8 are in close contact with the upper end face of the automotive wheel bracket workpiece 2.

[0065] The rotary pressing cylinders 8 rotate and press downwards, applying a downward pressure to the automotive wheel bracket workpiece to ensure that the automotive wheel bracket workpiece does not shift during processing.

[0066] While ensuring the continuous and stable positioning of workpiece processing, this processing fixture for an automotive wheel bracket enables adjustable auxiliary clamping in the remaining degree-of-freedom directions, making the fixture structure as open as possible. This can not only simplify the clamping mechanism, reduce the clamping force, but also fully expose the surface to be processed, avoiding interference during the processing process.

[0067] This processing fixture for an automotive wheel bracket ensures the rigidity of the fixture itself, enabling the workpiece to be stably installed, evenly stressed, and reliably clamped, with the minimum deformation caused by cutting force and clamping force.

[0068] Working principle: When in use, open the fixture to release it, place the automotive wheel bracket workpiece on the fixture. The lower end face of the automotive wheel bracket workpiece fits against the positioning reference seat 3. Adjust the automotive wheel bracket workpiece so that it fits against the tight-fitting piece 6 and the angular auxiliary positioning piece. Then start the inclined support component, so that the telescopic cylinder component 7 clamps the automotive wheel bracket workpiece laterally. At this time, start the rotary pressing cylinder 8, and the rotary pressing cylinder 8 rotates and presses down to clamp, realizing the clamping of the automotive wheel bracket, and then the processing can be carried out.

[0069] The processing fixture for an automotive wheel bracket recorded in the present utility model has a moderate manufacturing cost, improves the qualified rate of one-time processing, and reduces subsequent investment and labor costs.

[0070] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
