[0071] In some embodiments of the present application, as shown in Figures 1-2 , the conveying system includes a tray 1, a roller 2, a lifting machine 3, a translation machine 4, a turnover machine 5, a box 6, a box transfer machine 7 and a rack 8;

[0072] The tray 1 is used to place the workpiece 10 to be processed, and the lifting machine 3 is installed at the head end of the roller 2, and the lifting machine 3 is used to lift the tray 1 onto the roller 2;

[0073] The translation machine 4 and the turnover machine 5 are located on the side of the roller 2, and the roller 2 is used to convey the tray 1 to the translation machine 4 and the turnover machine 5;

[0074] The translation machine 4 is used to move the tray 1 into and out of the processing station;

[0075] The turnover machine 5 is used to turn over the workpiece 10 on the tray 1 and put the workpiece 10 into the box 6;

[0076] The box transfer machine 7 is used to convey the box 6 to the rack 8.

[0077] In this embodiment, as shown in Figure 4 , the workpiece 10 to be processed is a knuckle, and the bearing and hub need to be press-fitted onto the knuckle. Before the hub is press-fitted, the worker needs to manually install the splash guard.

[0078] As shown in Figure 3 , the roller 2 is arranged in a straight line direction, and the roller 2 is used to move the tray 1 to different positions, and a plurality of stoppers are also provided on the roller 2. When the tray 1 reaches a certain processing station, the stopper rises to block the tray 1, so that the tray 1 is kept at that position. When the processing is completed, the stopper is lowered, and the tray 1 moves towards the next processing station.

[0079] As shown in Figures 1-2As shown, the elevator 3 lifts the tray 1 to the roller bed 2; the worker places the workpiece 10 on the tray 1; the roller bed 2 brings the tray 1 to the translation machine 4; the translation machine 4 pushes the tray 1 and the workpiece 10 into the bearing press-fitting machine 20 in a direction perpendicular to the roller bed 2; the bearing press-fitting machine 20 press-fits the bearing onto the knuckle; then the translation machine 4 pulls the tray 1 and the workpiece 10 back to the roller bed 2; the tray 1 continues to move to the next station on the roller bed 2, and the worker manually installs the splash guard, fastens the switch bracket to the knuckle, and then places the hub part onto the tray 1; the purpose of the splash guard is to prevent sand and dirt from entering the hub and causing abnormal noise or damage; the tray 1 continues to move to the next translation machine 4, which pushes the tray 1 and the workpiece 10 into the hub press-fitting machine 30; the hub press-fitting machine 30 press-fits the hub onto the bearing of the knuckle; then the translation machine 4 pulls the tray 1 and the workpiece 10 back to the roller bed 2; the tray 1 continues to move forward to the turnover machine 5, which clamps the workpiece 10 and places it into the magazine 6 after turning it over; the magazine transfer machine 7 transports the magazine 6 to the magazine rack 8, which includes multiple layers and columns and can load multiple magazines 6. When the magazine rack 8 is full, it is removed and replaced with an empty one.

[0080] The embodiment transports the tray 1 and the workpiece 10 to each station through the roller bed 2, then moves the workpiece into the processing machine through the translation machine 4, moves the workpiece 10 out of the processing machine after processing, and finally places the workpiece 10 into the magazine 6 after turning it over through the turnover machine 5, and the magazine transfer machine 7 moves the magazine 6 to the magazine rack 8. The embodiment realizes mechanized transportation and handling of workpieces, greatly saving manpower and improving work efficiency.

[0081] Further, as shown, Figure 2 The translation machine 4 has two machines, corresponding to the bearing press-fitting station and the hub press-fitting station respectively;

[0082] The roller bed 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 elevator 3 lifts the tray 1 to the roller bed 2, the tray 1 is located at the first station A;

[0084] When the tray 1 moves to the corresponding bearing press-fitting station, the tray 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 turnover machine 5, the tray 1 is located at the fifth station E.

[0088] Specifically, at the first station A, the tray 1 is lifted onto the roller way 2 from the lifting machine 3, and the worker at the first station A puts the workpiece 10 to be machined into the tray 1;

[0089] At the second station B, the translation machine 4 pushes the tray 1 and the workpiece 10 to be machined into the bearing press-fitting machine 20 together, and after the bearing is press-fitted, the translation machine 4 pulls the tray 1 and the workpiece 10 to be machined back onto the roller way 2 again.

[0090] At the third station C, the worker fastens the splash guard and the switch bracket to the knuckle, and then puts the hub part into the tray 1, and the purpose of the splash guard is to block sand and dirt from entering the hub and causing abnormal noise or damage.

[0091] At the fourth station D, the translation machine 4 pushes the tray 1 and the workpiece 10 to be machined into the hub press-fitting machine 30 together, and after the hub is press-fitted, the translation machine 4 pulls the tray 1 and the workpiece 10 to be machined back onto the roller way 2 again.

[0092] At the fifth station E, the turnover machine 5 clamps the workpiece 10 to be machined from the tray 1, and then turns over and puts the workpiece 10 to be machined into the box 6.

[0093] In this embodiment, the roller way 2 brings the tray 1 to each station, facilitating each machining step of the workpiece 10 to be machined, reducing manual handling and movement, greatly saving manpower, and improving work efficiency.

[0094] Further, as shown in the drawings, Figures 4-5 The tray 1 includes a bottom plate 11, the middle part of the bottom plate 11 is hollow, the bottom plate 11 is provided with a first positioning piece 12 and a second positioning piece 13, the first positioning piece 12 is located at one side edge of the bottom plate 11, the second positioning piece 13 is located at the other side edge of the bottom plate 11, the first positioning piece 12 is used for positioning one side of the workpiece 10 to be machined, and the second positioning piece 13 is used for positioning the other side of the workpiece 10 to be machined; the opposite two side edges of the bottom plate 11 are also provided with clamped parts 14, which are used for cooperation with the translation machine 4.

[0095] Specifically, Figure 4 the upper surface of the tray 1, Figure 5 the lower surface of the tray 1. The bottom plate 11 is a rectangular frame structure, and the middle part of the bottom plate 11 is hollow, facilitating the partial structure of the workpiece 10 to be machined to extend below the tray 1.

[0096] As shown in the drawings, Figure 4 The first positioning piece 12 has two, which are cylindrical and arranged on one side edge of the bottom plate 11, and the first positioning piece 12 is used for positioning two mounting columns on the workpiece 10 to be machined.

[0097] As shown in the drawings, Figure 5As shown, the second positioning member 13 has one, and the second positioning member 13 is also cylindrical, extending from the other side of the chassis 11 to the hollow part of the chassis 11, and then extending upward to contact and position the bottom of the workpiece 10.

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

[0099] As shown in the drawings, Figure 4 The upper surface of the chassis 11 is provided with a clamped part 14 on each of the opposite sides, and a through hole is formed in the clamped part 14. The translation machine 4 brings the tray 1 away from the roller way 2 by clamping the clamped part 14, and pushes the tray 1 and the workpiece 10 into the bearing press-fitting machine 20 and the hub press-fitting machine 30. The structure of the translation machine 4 corresponding to the clamped part 14 will be described in detail later.

[0100] Further, as shown in the drawings, Figure 15 The roller way 2 is also provided with a tray lifting assembly 21, which is arranged at the second station B and the fourth station D. The tray lifting assembly 21 includes a lifting platform 211 and a positioning column 212, and the positioning column 212 is installed on the lifting platform 211. The chassis 11 is provided with a positioning hole 15 on each of the opposite sides, and the positioning column 212 is matched with the positioning hole 15 when it is raised.

[0101] Specifically, as shown in the drawings, Figure 4 The opposite sides of the chassis 11 are each provided with a positioning hole 15. As shown in the drawings, Figure 15 The two positioning columns 212 correspond to the two positioning holes 15.

[0102] The tray lifting assembly 21 also includes a lifting motor 214 and a base 213, and the base 213 is fixedly installed below the roller way 2. The lifting motor 214 is connected to the center of the lifting platform 211 through the base 213.

[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 station, the lifting motor 214 is raised, and the two positioning columns 212 are inserted into the two positioning holes 15 respectively. The tray 1 and the workpiece 10 are lifted, which facilitates the clamping of the tray 1 by the translation machine 4.

[0105] When the translation machine 4 clamps the tray 1 and lifts it up, the tray 1 is separated from the positioning column 212, and the lifting motor 214 is retracted to the initial state.

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

[0107] Furthermore, such as Figure 16 As shown, the roller conveyor 2 is also equipped with a workpiece lifting assembly 22. The workpiece lifting assembly 22 is set at the third station C and the fifth station E. The workpiece lifting assembly 22 includes a base platform 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 platform 221. The base platform 221 can move up and down. The first lifting member 222 and the second lifting member 223 cooperate with two parts on the workpiece 10 to be processed.

[0108] Specifically, the workpiece lifting assembly 22 also includes a lifting motor 225 and a base 224. The base 224 is fixedly connected to the roller conveyor 2, and 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 retracts, and the base platform 221, the first lifting member 222, and the second lifting member 223 all retract to a position that does not interfere with the tray 1.

[0110] When pallet 1 moves to the third station C or the fifth station E, the lifting motor 225 rises upward, and the base platform 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 bottom two parts of the workpiece 10 to be processed. The base platform 221 passes through the middle of the chassis 11 and only lifts the workpiece 10 to be processed. At this time, pallet 1 is still on the roller conveyor 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 guard and bracket. At the same time, the worker needs to take a new wheel hub and place it on the workpiece 10. After the installation is completed, the workpiece lifting assembly 22 lowers and places the workpiece 10 on the tray 1.

[0112] Similarly, at the fifth station E, the flipping machine 5 needs to clamp and flip the workpiece 10 to be processed. Therefore, the workpiece lifting assembly 22 lifts the workpiece 10 to be processed, which is beneficial for the flipping machine 5 to clamp the workpiece 10 to be processed.

[0113] Better, such as Figures 4-5 As shown, the front and rear ends of the chassis 11 are also provided with slots 16. The slots 16 can cooperate with the stopper. The stopper is installed on the roller conveyor 2. When the stopper is raised, it engages with the slots 16 to keep the pallet 1 in each set position.

[0114] Furthermore, such as 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 clamping unit 43 is used for clamping the tray 1;

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

[0117] The forward moving unit 42 is used for driving the clamping unit 43 to move towards or away from the processing station.

[0118] Specifically, the lifting unit 41 includes a lifting motor, a sliding block and a longitudinal sliding rail, the sliding block is connected with the forward moving unit 42, the lifting unit 41 can drive the forward moving unit 42 to move up and down along the longitudinal direction, and the lifting unit 41 is used for driving the tray 1 and the workpiece 10 to be lifted up or to be dropped down.

[0119] The forward moving unit 42 includes a motor, a sliding block and a transverse sliding rail, the transverse sliding rail is perpendicular to the length direction of the roller way 2 and extends towards the direction of the bearing press fitting machine 20. The forward moving unit 42 can drive the clamping unit 43 to move back and forth along the transverse direction.

[0120] The clamping unit 43 is used for clamping the tray 1, and then driving the tray 1 to move towards the bearing press fitting machine 20 under the driving of the lifting unit 41 and the forward moving unit 42.

[0121] Further, as shown in Figures 6-8 , the clamping unit 43 includes a clamping motor 431, a first clamping plate 432, a second clamping plate 433 and a linkage assembly 434, the clamping motor 431 is used for driving the first clamping plate 432 to move, and the linkage assembly 434 connects the first clamping plate 432 and the second clamping plate 433. When the first clamping plate 432 moves, the second clamping plate 433 is driven to move towards the direction of approaching or moving away from the first clamping plate 432 through the linkage assembly 434.

[0122] Specifically, as shown in Figure 6 , the clamping unit 43 includes the first clamping plate 432 and the second clamping plate 433, and the two clamping plates are respectively used for clamping the clamped part 14 on the bottom disc 11. The first clamping plate 432 extends a first plug 435 thereon, and the second clamping plate 433 extends a second plug 436 thereon. The first plug 435 and the second plug 436 are used for being inserted into the through hole of the clamped part 14 to facilitate lifting the tray 1.

[0123] When the unit 43 holds the tray 1, the unit 42 moves the tray 1 to the upper side of the bearing press machine 20. Then the unit 43 releases the tray 1, and the unit 41 lifts the unit 42 and the unit 43 to avoid interference with the bearing press machine 20. After the bearing is pressed into the workpiece 10, the unit 41 is lowered, the unit 43 holds the tray 1 again, the unit 42 moves the tray 1 to the upper side of the roller 2, and the tray 1 falls on the roller 2 after the unit 43 releases the tray 1.

[0124] Preferably, as shown in Figure 8 The linkage assembly 434 connects the first closing plate 432 and the second closing plate 433, and realizes synchronous movement of the first closing plate 432 and the second closing plate 433, that is, 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 with the first closing plate 432, the second rack 4342 is connected with 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 towards 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 towards the first gear 4343 synchronously, thereby realizing the closing action. When the closing motor 431 is reversely driven, the first closing plate 432 and the second closing plate 433 are opened.

[0126] Further, as shown in Figure 9 The turnover machine 5 includes a lifting unit 51, a clamping unit 52 and a turnover unit 53;

[0127] The clamping unit 52 is used for clamping the workpiece 10;

[0128] The turnover unit 53 is used for driving the clamping unit 52 to turn over;

[0129] The lifting unit 51 is used for driving the clamping unit 52 and the turnover unit 53 to move up and down.

[0130] Specifically, Figure 9 The turnover machine 5 has two machines arranged side by side, which can turn over two workpieces 10 at the same time, improving the work efficiency.
