[0020] In the description of the embodiments of the utility model, it needs to be explained that the directions or position relations indicated by the terms "inner", "outer", "upper" and the like are based on the directions or position relations shown in the drawings, or are the directions or position relations in which the utility model product is usually placed during use, and are only for the convenience of describing the utility model and simplifying the description, and thus cannot be understood as limiting the utility model in that the indicated devices or elements must have a specific direction, be constructed and operated in a specific direction, and thus cannot be understood as limiting the utility model.

[0021] As shown in Figure 4 and Figure 5 shown, the five positioning columns 55 of the hub bearing 5 need to cooperate with the five through holes 43 of the brake disc 4 in the embodiment, and the tightening hole 44 of the brake disc 4 needs to cooperate with the threaded hole 56 of the hub bearing 5 for bolt connection to form a whole.

[0022] As shown in Figure 1 shown, the embodiment comprises: a positioning assembly 1 comprising a high support 11 for limiting the position of the brake disc 4, a low support 12 connected below the top surface of the high support 11, the low support 12 being fixed in position relative to the high support 11, the low support 12 being capable of identifying the position of the tightening hole 44 of the brake disc 4 relative to the high support 11; and a mold assembly 2 fixed in position relative to the positioning assembly 1, the mold assembly 2 being capable of limiting the position of the hub bearing 5 and identifying the position of the threaded hole 56 of the hub bearing 5 relative to the tightening hole 44 of the brake disc 4; and a clamping assembly 3 fixed in position relative to the positioning assembly 1, the clamping assembly 3 being capable of stacking the brake disc 4 above the hub bearing 5 according to the position of the tightening hole 44 relative to the threaded hole 56.

[0023] Specifically, the positioning assembly 1, the mold assembly 2 and the clamping assembly 3 are all fixedly installed on the ground to form fixed relative positions.

[0024] Specifically, the main body structures of the high support 11 and the low support 12 are both welded from square tubes, and the two are welded together to fix the relative positions of the two; wherein the top surface of the high support 11 forms a fixed structure for limiting the position of the brake disc 4, such as a limiting block or a groove matched with the shape of the brake disc 4, so that the position of the brake disc 4 relative to the low support 12 is fixed, the low support 12 identifies the position of the tightening hole 44 of the brake disc 4 relative to the high support 11 through a visual camera, so that the relative positions of the low support 12, the high support 11 and the tightening hole 44 are fixed, and thus the position of the tightening hole 44 can be determined after the position of the high support 11 is determined.

[0025] Secondly, the position of the mold assembly 2 is relatively fixed with the position of the positioning assembly 1, that is, the position of the high support 11, and further the position of the tightening hole 44 of the brake disc 4, wherein the mold assembly 2 also forms a fixed structure for limiting the position of the hub bearing 5, such as a limiting block or a groove matched with the shape of the hub bearing 5, so that the position of the hub bearing 5 relative to the mold assembly 2 is fixed. The mold assembly 2 identifies the position of the threaded hole 56 of the hub bearing 5 relative to the fixed structure of the mold assembly 2 through a visual camera, and further obtains the position of the threaded hole 56 of the hub bearing 5 relative to the positioning assembly 1, and further obtains the position of the threaded hole 56 of the hub bearing 5 relative to the high support 11, and further obtains the position of the threaded hole 44 of the brake disc 4 relative to the high support 11, and further enables the clamping assembly 3 to align the threaded hole 44 of the brake disc 4 with the threaded hole 56 of the hub bearing 5 during the stacking of the two, and further enables the bolt to pass through the two holes, so that the two form an integral whole.

[0026] As shown in Figure 2 the high support 11 includes: a mounting table 111 for placing the brake disc 4, the top surface of the mounting table 111 being a horizontal plane; L-shaped mounting blocks 113 evenly distributed on the top surface of the mounting table 111 in the circumferential direction, the vertical side surface of the L-shaped mounting block 113 being perpendicular to the top surface of the mounting table 111 and close to the brake disc 4, the vertical side surface of the L-shaped mounting block 113 being connected with a first limiting column 114, one side of the first limiting column 114 close to the brake disc 4 forming a curved surface for guiding the movement of the brake disc 4; a limiting protrusion 115 provided on the top surface of the mounting table 111, the axis of the limiting protrusion 115 coinciding with the axis of the brake disc 4, the top surface of the limiting protrusion 115 being higher than the top surface of the mounting table 111, and the top surface of the limiting protrusion 115 being able to coincide with the middle surface of the brake disc 4.

[0027] Specifically, the brake disc 4 is placed on the horizontal mounting table 111, so that the bottom surface of the brake disc 4 and the mounting table 111 are both horizontal planes, so that there is no positional deviation when the low support 12 identifies the position of the brake disc 4 relative to the mounting table 111; secondly, the mounting table 111 is equally angularly provided with four L-shaped mounting blocks 113, the outer side surface of the L-shaped mounting block 113 being L-shaped, one side surface thereof being mounted on the mounting table 111 by a bolt, and the other vertical side surface thereof being provided with a replaceable gasket, and being connected with the first limiting column 114 by a bolt, the top end of the first limiting column 114 being conical, and being able to guide the brake disc 4 into the fixed brake disc 4 structure formed by the four first limiting columns 114, wherein the area of the limiting region surrounded by the four first limiting columns 114 can be adjusted by adjusting the thickness of the gasket, and further matched with the diameter of the brake disc 4, so that there is no gap between the brake disc 4 and the first limiting column 114, and further ensuring the relative position between the brake disc 4 and the high support 11, and further ensuring the position of the tightening hole 44 relative to the high support 11.

[0028] Secondly, the top surface of the limiting protrusion 115 is curved. Because the contact surface between the brake disc 4 and the limiting protrusion 115 is concave, the two can overlap. The limiting protrusion 115 is fixedly installed in the middle position of the limiting area to coincide with the axis of the brake disc 4, further restricting the position of the brake disc 4.

[0029] Furthermore, the high bracket 11 also includes a transmission hole 112 that uniformly penetrates the mounting platform 111 in the circumferential direction; the low bracket 12 includes a first camera 121 fixedly connected to the high bracket 11, the vertical projection of the tightening hole 44 of the brake disc 4 can pass through the transmission hole 112 and enter the field of view of the first camera 121, and the first camera 121 can calculate the position of the tightening hole 44 relative to the high bracket 11.

[0030] Specifically, the mounting platform 111 forms three transmission holes 112, which are evenly distributed along the axis and coincide with the axis of the first camera 121. The first camera 121 is provided with a ring light source around its circumference, which can provide sufficient light to the first camera 121 to ensure its shooting effect. The shape of the transmission hole 112 is an arc-shaped waist hole. The diameter of the arc where the center of the tightening hole 44 of the brake disc 4 is located is within the arc diameter range of the arc-shaped waist hole, so that the vertical projection of the tightening hole 44 onto the first camera 121 can be transmitted through the transmission hole 112 and fall within the field of view of the first camera 121. This allows the first camera 121 to identify the position of the tightening hole 44 relative to the high bracket 11, and then to identify the position of the tightening hole 44 relative to the mold assembly 2.

[0031] like Figure 3 As shown, the mold assembly 2 includes: a limiting platform 21 fixed in a relative position to the positioning assembly 1, the top surface of which forms a groove for placing the bearing mounting ring 51 of the wheel hub bearing 5; at least four second limiting posts 22 disposed on the top surface of the limiting platform 21, the second limiting posts 22 being arranged in pairs to limit the mounting ears 53 of the wheel hub bearing 5; and a third camera 23 disposed directly above the limiting platform 21, the vertical projection of which can cover the wheel hub bearing 5, and the third camera 23 being able to identify the position of the threaded hole 56 of the wheel hub bearing 5 relative to the limiting platform 21.

[0032] Specifically, the relative position of the limiting table 21 and the high support 11 is fixed, which can limit the placement position of the hub bearing 5. During assembly, the middle protruding bearing mounting ring 51 of the hub bearing 5 is placed towards the limiting table 21, and the second layer mounting disc 54 thereof is away from the limiting table 21 to be assembled with the brake disc 4. Therefore, the groove formed on the top surface of the limiting table 21 can place the protruding bearing mounting ring 51, and the first layer mounting protrusion 52 can be in contact with the top surface of the limiting table 21, so that the second limiting column 22 on the top surface can be in contact with the side surface of the first layer mounting lug 53, thereby limiting the rotation and horizontal position of the mounting lug 53, and further limiting the horizontal position of the hub bearing 5 relative to the limiting table 21. Secondly, the third camera 23 is arranged directly above the limiting table 21, and the field of view thereof can cover the limiting table 21, so that it can identify the position of the hub bearing 5 relative to the limiting table 21, and further identify the position of the threaded hole 56 of the hub bearing 5 relative to the limiting table 21, and further obtain the position of the threaded hole 56 relative to the tightening hole 44.

[0033] Secondly, the low support 12 further comprises a second camera 122 fixedly connected with the high support 11. The lens height of the second camera 122 is the same as that of the first camera 121. The second camera 122 can identify the position of the mounting lug 53 of the hub bearing 5, so that the robot 31 can determine the position of the mounting lug 53 relative to itself during clamping the hub bearing 5 through the second camera 122, and further enable the robot 31 to correctly place the mounting lug 53 in the middle of the second limiting column 22, so that the second limiting columns 22 are placed on both sides of the same mounting lug 53, thereby limiting the rotation of the mounting lug 53 relative to the limiting table 21, and further limiting the position of the hub bearing 5.

[0034] Further, the clamping assembly 3 comprises a robot 31 for carrying the brake disc 4 or the hub bearing 5. The movement end of the robot 31 is respectively provided with a brake disc clamping piece 32 and a hub bearing clamping piece 33.

[0035] Specifically, the first camera 121 can identify the position of the tightening hole 44 relative to the high support 11, and the third camera 23 can identify the position of the threaded hole 56 relative to the limiting table 21. Since the positions of the high support 11, the limiting table 21 and the robot 31 are all fixed values, the robot 31 can know the positions of the tightening hole 44 relative to the threaded hole 56 and itself, and further enable the movement end of the robot 31 to drive the brake disc clamping piece 32 to clamp the brake disc 4, so that the brake disc 4 is stacked on the top surface of the hub bearing 5, and the axis of the brake disc clamping piece 32 is aligned with the axis of the hub bearing 5, and the tightening hole 44 is aligned with the threaded hole 56, so that the brake disc 4 and the hub bearing 5 can be connected into one through bolts, thereby avoiding the phenomenon of rework due to the misalignment of the tightening hole 44 and the threaded hole 56 during stacking, and improving the production efficiency. The hub bearing clamping piece 33 can carry the hub bearing 5 above the limiting table 21 to fix the position thereof.

[0036] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
