[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0033] The following further describes the present utility model in conjunction with embodiments.

[0034] In the following description, the "left", "right", "front", "rear", "upper", and "lower" mentioned are oriented in the perspective direction of the front view.

[0035] In some embodiments, referring to the attached drawings of the specification Figures 1-6 , an auxiliary device for processing automotive parts that is convenient for positioning, includes a workbench 1;

[0036] A limiting column 11 for limiting and placing a hub 9 is fixedly connected to the top of the workbench 1;

[0037] A lifting assembly 2 is placed on the ground at the rear side of the workbench 1, and a moving plate 3 is connected to the lifting assembly 2;

[0038] A driving assembly 4 is arranged on the moving plate 3, the moving plate 3 is connected to a support plate 5 through the driving assembly 4, two support plates 5 are symmetrically arranged, and the driving assembly 4 is used to drive the support plate 5 to move;

[0039] A clamping seat 6 is rotatably connected to the support plate 5, a clamping assembly 7 for clamping hubs 9 of various sizes is arranged on the clamping seat 6, and a rotating assembly 8 for driving the clamping seat 6 to rotate is arranged on the outer wall of the left support plate 5.

[0040] When the present utility model is in use, the frictional force between the clamping seat 6 and the support plate 5 will prevent the clamping seat 6 from rotating by itself. By controlling the driving assembly 4 to drive the symmetrically arranged support plates 5 to move synchronously towards each other, and enabling the clamping assembly 7 to quickly clamp the hub 9. Subsequently, by controlling the lifting assembly 2 to drive the moving plate 3 to lift, the moving plate 3 drives the support plate 5 to lift, so that the clamping assembly 7 drives the hub 9 to lift, causing the hub 9 to separate from the limiting column 11. After the hub 9 rises to a set height, control the rotating assembly 8 to drive the clamping seat 6 to rotate, and the clamping seat 6 drives the clamping assembly 7 to rotate, thereby driving the hub 9 to rotate. After the hub 9 rotates 180 degrees, the moving plate 3 resets to drive the hub 9 to be inserted into the limiting column 11, realizing the limiting and fixing of the flipped hub 9, which is convenient for processing both sides of the hub 9;

[0041] When the hub 9 rises to a set height, processing operations such as painting can be performed. When the hub 9 is inserted into the limiting column 11, the bearing capacity of the processing surface is further enhanced, and processing operations such as milling can be performed. This device can perform processing of multiple processes and has strong operability.

[0042] The lifting assembly 2 includes a base 21 and a linear module 22. The base 21 is placed on the ground at the rear side of the workbench 1, and the linear module 22 is fixedly installed on the base 21;

[0043] After the linear module 22 lifts the moving plate 3 to the set height, the clamping component 7 drives the hub 9 to move to the set height, thus providing space for the flipping of the hub 9;

[0044] The moving plate 3 is fixedly installed on the moving end of the linear module 22;

[0045] The driving component 4 includes a bidirectional lead screw 41 and a motor 42. The two ends of the bidirectional lead screw 41 are respectively threadedly connected to the symmetrically arranged support plates 5. A moving groove is formed in the moving plate 3, and the bidirectional lead screw 41 is rotatably connected in the moving groove. The motor 42 is fixedly installed at the right end of the moving plate 3, and the output end of the motor 42 is fixedly connected to the right end of the bidirectional lead screw 41;

[0046] The support plate 5 is in limiting sliding connection with the moving groove of the moving plate 3;

[0047] Before processing, the hub 9 and the limiting column 11 are in an inserted state. After the processing starts, the motor 42 is controlled to drive the bidirectional lead screw 41 to rotate. The bidirectional lead screw 41 will drive the symmetrically arranged support plates 5 to move towards each other, thereby driving the symmetrically arranged clamping components 7 to move synchronously to the hub 9 and clamp the hub 9, and ensuring that the hub 9 and the limiting column 11 are always on the same axis. After controlling the rotating component 8 to drive the clamping seat 6 to flip, the clamping component 7 drives the hub 9 to flip. After the flipping is completed, the axis of the hub 9 still coincides with the axis of the limiting column 11, which is convenient for the quick fixation after the hub 9 is flipped, is beneficial to accelerating the processing speed, will not cause the axis of the hub 9 to deviate from the axis of the limiting column 11, and improves the processing accuracy;

[0048] The clamping component 7 includes an arc block 71, a bent plate 72 and a friction pad 73. The arc block 71 is fixedly connected to the inner end of the clamping seat 6, the friction pad 73 is fixedly connected to the inner end of the arc block 71, and the two ends of the arc block 71 are rotatably connected to the bent plate 72 through a rotating pin.

[0049] A torsion spring is arranged on the rotating pin. One end of the torsion spring is fixedly connected to the arc block 71, and the other end of the torsion spring is fixedly connected to the bent plate 72;

[0050] Since the bent plate 72 is connected to the arc block 71 through a torsion spring, when the bent plate 72 clamps hubs 9 of different sizes, the bent plate 72 will open or shrink to adapt to hubs 9 of different sizes. When the clamping component 7 clamps the hub 9, the bent plate 72 first fits against the inner wall of the hub 9, and then the friction pad 73 fits against the inner wall of the hub 9 and applies pressure to the inner wall of the hub 9. The friction pads 73 on the left and right sides of the hub 9 apply pressure to the hub 9 to fix the hub 9. The bent plate 72 changes its angle according to the shape of the inner wall of the hub 9 and increases the friction area with the hub 9, further increasing the clamping stability of the hub 9 during the up and down movement;

[0051] The rotating assembly 8 includes a mounting bracket 81 and a rotary cylinder 82. The mounting bracket 81 is fixedly installed on the outer wall of the support plate 5 on the left side of the moving plate 3, and the rotary cylinder 82 is fixedly installed on the mounting bracket 81. The output end of the rotary cylinder 82 is fixedly connected to the tail end of the clamping seat 6 on the left side of the moving plate 3;

[0052] The rotary cylinder 82 is set as a rotary cylinder that can rotate 180 degrees. When the wheel hub 9 is lifted to the set height, the rotary cylinder 82 is controlled to drive the clamping seat 6 to rotate 180 degrees, so that both sides of the wheel hub 9 can be processed, and the wheel hub 9 always faces up either on the front or the back, avoiding the situation that the wheel hub 9 is not level, and ensuring the subsequent clamping and processing accuracy of the wheel hub 9;

[0053] In some embodiments, refer to the attached drawings of the specification Figure 7 , an electromagnet 10 is installed on the side wall of the support plate 5 away from the rotating assembly 8. A socket for inserting the plug rod of the electromagnet 10 is provided on the rotating shaft of the clamping seat 6 away from the rotating assembly 8. When the plug rod of the electromagnet 10 is inserted into the socket, the arc block 71 away from the rotating assembly 8 is in a horizontal state;

[0054] After the clamping seat 6 rotates, the electromagnet is powered off, and the plug rod of the electromagnet 10 is inserted into the socket provided on the clamping seat 6 to horizontally lock the clamping seat 6; when the clamping seat 6 is not rotating, the plug rod of the electromagnet is always inserted into the socket provided on the clamping seat 6, and when the clamping seat 6 rotates, the plug rod of the electromagnet 10 is separated from the clamping seat 6, ensuring that the states of the two clamping seats 6 are the same when the clamping seat 6 needs to rotate.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
