[0078] like Figure 3 As shown, the roller conveyor 2 is arranged in a straight line, and is used to drive the pallet 1 to move to different positions. The roller conveyor 2 is also provided with a plurality of stoppers. When the pallet 1 reaches a certain processing station, the stopper rises to stop the pallet 1, so that the pallet 1 remains at the position. When the processing is completed, the stopper falls, and the pallet 1 moves toward the next processing station.

[0079] like Figure 1-Figure 2As shown, the hoist 3 lifts the pallet 1 onto the roller table 2; the worker places the workpiece 10 to be processed on the pallet 1; the roller table 2 brings the pallet 1 to the translation machine 4; the translation machine 4 pushes the pallet 1 and the workpiece 10 to be processed into the bearing press 20 in a direction perpendicular to the roller table 2; the bearing press 20 presses the bearing onto the steering knuckle; then the translation machine 4 pulls the pallet 1 and the workpiece 10 back onto the roller table 2; the pallet 1 continues to move to the next station on the roller table 2, and the worker manually installs the splash guard, fastens the splash guard and the switch bracket to the steering knuckle, and then puts the wheel hub parts onto the pallet 1. The purpose of the splash guard is to prevent The pallet 1 continues to move to the next translation machine 4, which pushes the pallet 1 and the workpiece 10 to be processed into the wheel hub press 30; the wheel hub press 30 presses the wheel hub onto the bearing of the steering knuckle; then the translation machine 4 pulls the pallet 1 and the workpiece 10 back to the roller 2; the pallet 1 continues to move forward to the flip machine 5, which clamps the workpiece 10 to be processed, flips it and puts it into the material box 6; the material box transfer machine 7 transports the material box 6 to the material rack 8, which includes multiple layers and multiple columns, and can realize the loading of multiple material boxes 6. When the material rack 8 is full, the material rack 8 is removed and another empty material rack 8 is put in.

[0080] In this embodiment, the tray 1 and the workpiece 10 to be processed are transported to each workstation by the roller 2, and then the workpiece 10 to be processed is moved into the processing machine by the translation machine 4, and the workpiece 10 to be processed is moved out of the processing machine after processing, and finally the workpiece 10 to be processed is turned over by the turning machine 5 and put into the material box 6, and the material box transfer machine 7 moves the material box 6 to the material rack 8. This embodiment realizes the mechanized transportation and handling of the workpiece to be processed, which greatly saves manpower and improves work efficiency.

[0081] Furthermore, if Figure 2 As shown, there are two translation machines 4, corresponding to the bearing press-fitting station and the hub press-fitting station respectively;

[0082] The roller table 2 includes a first station A, a second station B, a third station C, a fourth station D and a fifth station E;

[0083] When the hoist 3 lifts the pallet 1 onto the roller table 2, the pallet 1 is located at the first station A;

[0084] When the pallet 1 moves to the corresponding bearing pressing station, the pallet 1 is located at the second station B;

[0085] When the tray 1 moves to the corresponding hub press-fitting station, the tray 1 is located at the fourth station D;

[0086] The third station C is located between the second station B and the fourth station D;

[0087] When the tray 1 moves to the corresponding turning machine 5 , the tray 1 is located at the fifth station E.

[0088] Specifically, at the first workstation A, the pallet 1 is lifted from the elevator 3 to the roller table 2, and the worker puts the workpiece 10 to be processed into the pallet 1 at the first workstation A;

[0089] At the second station B, the translator 4 pushes the pallet 1 and the workpiece 10 to be processed into the bearing press 20. After the bearing is pressed, the translator 4 pulls the pallet 1 and the workpiece 10 back to the roller table 2.

[0090] At the third station C, the worker fastens the splash plate and switch bracket to the steering knuckle, and then puts the wheel hub parts on the tray 1. The purpose of the splash plate is to prevent sand and dirt from entering the wheel hub and causing abnormal noise or damage;

[0091] At the fourth station D, the translator 4 pushes the tray 1 and the workpiece 10 to be processed into the hub press machine 30. After the hub is pressed, the translator 4 pulls the tray 1 and the workpiece 10 back to the roller table 2.

[0092] At the fifth station E, the turning machine 5 clamps the workpiece 10 to be processed from the tray 1 , then turns the workpiece 10 to be processed over and places it into the material box 6 .

[0093] In this embodiment, the roller 2 brings the tray 1 to each workstation, which facilitates various processing steps for the workpiece 10 to be processed, reduces manual handling and movement, greatly saves manpower, and improves work efficiency.

[0094] Furthermore, if Figure 4-Figure 5 As shown, the pallet 1 includes a chassis 11, the middle part of which is hollow, and a first positioning member 12 and a second positioning member 13 are provided on the chassis 11. The first positioning member 12 is located on one side of the chassis 11, and the second positioning member 13 is located on the other side of the chassis 11. The first positioning member 12 is used to position one side of the workpiece 10 to be processed, and the second positioning member 13 is used to position the other side of the workpiece 10 to be processed; clamped portions 14 are also provided on the opposite two side edges of the chassis 11, and the clamped portions 14 are used to cooperate with the translation machine 4.

[0095] Specifically, Figure 4 is the upper surface of the tray 1, Figure 5 It is the lower surface of the tray 1. The chassis 11 is a rectangular frame structure, and the middle of the chassis 11 is hollowed out to facilitate the partial structure of the workpiece 10 to be processed to extend under the tray 1.

[0096] like Figure 4 As shown, there are two first positioning members 12 , which are cylindrical and arranged on one side of the chassis 11 . The first positioning members 12 are used to position two mounting columns on the workpiece 10 to be processed.

[0097] like Figure 5As shown, there is one second positioning member 13, which is also cylindrical and extends from the other side of the chassis 11 to the hollow portion of the chassis 11, and then extends upward to contact and position the bottom of the workpiece 10 to be processed.

[0098] In this embodiment, the workpiece 10 to be processed is positioned by means of two first positioning members 12 and one second positioning member 13 , so that the workpiece 10 to be processed can be stably placed on the pallet 1 .

[0099] like Figure 4 As shown, a clamped portion 14 is provided on opposite sides of the upper surface of the chassis 11, and a through hole is provided on the clamped portion 14. The translation machine 4 clamps the clamped portion 14 to separate the pallet 1 from the roller table 2, and pushes the pallet 1 and the workpiece 10 to be processed into the bearing press 20 and the wheel hub press 30. The structure corresponding to the clamped portion 14 on the translation machine 4 will be described in detail later.

[0100] Furthermore, if Fig.15 As shown, a pallet lifting assembly 21 is also provided on the roller conveyor 2. The pallet lifting assembly 21 is arranged at the second station B and the fourth station D. The pallet lifting assembly 21 includes a lifting platform 211 and a positioning column 212. The positioning column 212 is installed on the lifting platform 211. A positioning hole 15 is respectively provided on two opposite sides of the chassis 11. The positioning column 212 cooperates with the positioning hole 15 when it is raised.

[0101] Specifically, Figure 4 As shown, a positioning hole 15 is provided on each of the two opposite sides of the chassis 11. Fig.15 As shown, the two positioning posts 212 just correspond to the two positioning holes 15 .

[0102] The pallet lifting assembly 21 further includes a lifting motor 214 and a base 213 . The base 213 is fixedly installed below the roller conveyor 2 . The lifting motor 214 passes through the base 213 and is connected to the center of the lifting platform 211 .

[0103] In the initial state, the lifting motor 214 is retracted, and the lifting platform 211 and the positioning column 212 are also retracted to a height that does not interfere with the tray 1.

[0104] When the tray 1 moves to the designated workstation, the lifting motor 214 is raised, and the two positioning posts 212 are respectively inserted into the two positioning holes 15, so as to lift the tray 1 and the workpiece 10 to be processed, so that the translation machine 4 can clamp the tray 1.

[0105] When the translator 4 clamps the pallet 1 and lifts the pallet 1, the pallet 1 is separated from the positioning column 212, and the lifting motor 214 retracts to the initial state.

[0106] In this embodiment, the pallet lifting assembly 21 is arranged at the second station B and the fourth station D, corresponding to the positions of two translation machines 4, and needs to lift the pallet 1 and the workpiece 10 to be processed together.

[0107] Furthermore, if Fig.16 As shown, a workpiece lifting assembly 22 is also provided on the roller 2, and the workpiece lifting assembly 22 is arranged at the third station C and the fifth station E. The workpiece lifting assembly 22 includes a base 221, a first lifting member 222 and a second lifting member 223. The first lifting member 222 and the second lifting member 223 are installed on the base 221, and the base 221 can be lifted up and down. The first lifting member 222 and the second lifting member 223 cooperate with two places on the workpiece 10 to be processed.

[0108] Specifically, the workpiece lifting assembly 22 further includes a lifting motor 225 and a base 224 . The base 224 is fixedly connected to the roller table 2 . One end of the lifting motor 225 passes through the base 224 and is connected to the center of the bottom platform 221 .

[0109] In the initial state, the lifting motor 225 is retracted, and the base 221 , the first lifting member 222 and the second lifting member 223 are all retracted to positions that do not interfere with the tray 1 .

[0110] When the pallet 1 moves to the third station C or the fifth station E, the lifting motor 225 rises upward, the base 221, the first lifting member 222 and the second lifting member 223 are lifted, the first lifting member 222 and the second lifting member 223 contact the two bottom parts of the workpiece 10 to be processed, the base 221 passes through the middle hollow of the chassis 11, and only lifts the workpiece 10 to be processed. At this time, the pallet 1 is still on the roller 2.

[0111] At the third station C, the workpiece lifting assembly 22 lifts the workpiece 10 to be processed so that the worker can install the splash plate and the bracket. At the same time, the worker needs to take a new hub and place it on the workpiece 10 to be processed; after the installation is completed, the workpiece lifting assembly 22 descends and places the workpiece 10 on the pallet 1.

[0112] Likewise, at the fifth workstation E, the turning machine 5 needs to clamp and turn over the workpiece 10 to be processed, so the workpiece lifting assembly 22 lifts the workpiece 10 to be processed, which is beneficial for the turning machine 5 to clamp the workpiece 10 to be processed.

[0113] Preferably, if Figure 4-Figure 5 As shown, the front and rear ends of the chassis 11 are also provided with card slots 16, which can cooperate with the stopper, and the stopper is installed on the roller 2. When the stopper is raised, it engages with the card slot 16 to keep the pallet 1 at each set station.

[0114] Furthermore, if Figure 6 As shown, the translation machine 4 includes a lifting unit 41, a forward moving unit 42 and a closing unit 43;

[0115] The closing unit 43 is used to clamp the tray 1;

[0116] The lifting unit 41 is used to drive the forward moving unit 42 and the closing unit 43 to move up and down;

[0117] The forward moving unit 42 is used to drive the closing unit 43 to move toward or away from the processing station.

[0118] Specifically, the lifting unit 41 includes a lifting motor, a slider and a longitudinal slide rail. The slider is connected to the forward moving unit 42. The lifting unit 41 can drive the forward moving unit 42 to move up and down in the longitudinal direction. The lifting unit 41 is used to drive the tray 1 and the workpiece 10 to be processed to lift upward or fall back downward.

[0119] The forward moving unit 42 includes a motor, a slider and a transverse slide rail, wherein the transverse slide rail is perpendicular to the length direction of the roller table 2 and extends toward the bearing press 20. The forward moving unit 42 can drive the closing unit 43 to move back and forth in the transverse direction.

[0120] The closing unit 43 is used to clamp the tray 1 , and then, driven by the lifting unit 41 and the forward moving unit 42 , moves the tray toward the bearing press 20 .

[0121] Furthermore, if Figure 6-Figure 8 As shown, the closing unit 43 includes a closing motor 431, a first closing plate 432, a second closing plate 433 and a linkage assembly 434. The closing motor 431 is used to drive the first closing plate 432 to move. The linkage assembly 434 connects the first closing plate 432 and the second closing plate 433. When the first closing plate 432 moves, the second closing plate 433 is driven to move toward or away from the first closing plate 432 through the linkage assembly 434.

[0122] Specifically, Figure 6 As shown, the closing unit 43 includes a first closing plate 432 and a second closing plate 433, and the two closing plates are respectively used to clamp the clamped portion 14 on the chassis 11. Among them, a first latch 435 extends from the first closing plate 432, and a second latch 436 extends from the second closing plate 433. The first latch 435 and the second latch 436 are used to be inserted into the through hole on the clamped portion 14 to facilitate lifting the tray 1.

[0123] After the closing unit 43 lifts the pallet 1, the forward unit 42 brings the pallet 1 from above the roller 2 to above the bearing press 20. Then the closing unit 43 releases the pallet 1, so that the pallet 1 is located on the press station, and the lifting unit 41 drives the forward unit 42 and the closing unit 43 to lift to avoid interference with the bearing press 20. After the bearing is pressed onto the workpiece 10, the lifting unit 41 descends, the closing unit 43 lifts the pallet 1 again, and the forward unit 42 brings the pallet 1 back to above the roller 2. After the closing unit 43 releases the pallet 1, the pallet 1 falls back onto the roller 2.

[0124] Preferably, if Figure 8 As shown, the linkage assembly 434 connects the first closing plate 432 and the second closing plate 433 to achieve synchronous movement of the first closing plate 432 and the second closing plate 433, that is, to achieve synchronous closing or opening.

[0125] The linkage assembly 434 includes a first rack 4341, a second rack 4342 and a first gear 4343. The first rack 4341 is connected to the first closing plate 432, the second rack 4342 is connected to the second closing plate 433, and the first gear 4343 is located between the first closing plate 432 and the second closing plate 433. When the closing motor 431 drives the first closing plate 432 to move toward the direction of the first gear 4343, the first rack 4341 drives the first gear 4343 to rotate, the first gear 4343 synchronously drives the second rack 4342 to move, and the second rack 4342 drives the second closing plate 433 to move toward the direction of the first gear 4343 synchronously, thereby realizing the closing action. When the closing motor 431 is driven in the reverse direction, the first closing plate 432 and the second closing plate 433 are opened.

[0126] Furthermore, if Fig. 9 As shown, the turning machine 5 includes a lifting unit 51, a clamping unit 52 and a turning unit 53;

[0127] The clamping unit 52 is used to clamp the workpiece 10 to be processed;

[0128] The turning unit 53 is used to drive the clamping unit 52 to turn;
