For example, in the example of fig. 9 and 11, the first connection rod 1331 extends horizontally, both second connection rods 1332 extend vertically, and the first driving device 1311 may be provided on the second connection rods 1332. The support 1312 is formed as a rod-like structure. The lift assembly 131 may also include a mounting bar, which may be formed with the support 1312 in an "L" shaped configuration. Wherein the mounting rods are connected between the supports 1312 and the corresponding second connecting rods 1332, and the mounting rods are perpendicular to the first connecting rods 1331.

Thus, by making the supporting members 1312 be supporting rods, the supporting members 1312 are relatively small in size, so that while the workpiece 200 is effectively supported, the occupied space can be reduced, and the arrangement is more convenient. By making the supporting rod parallel to the first connecting rod 1331, it is ensured that the workpiece 200 can be kept in a horizontal state under the supporting action of the supporting rod 1214 when the workpiece 200 is in the lifting mode, so that the lifting stability of the workpiece 200 can be improved, and the workpiece 200 is prevented from being inclined in the lifting process.

For example, the protruding parts 1212 may be two, the two protruding parts 1212 are located at the sides of the third and fourth sides, respectively, and the two protruding parts 1212 protrude in the direction away from each other, respectively. The second driving means 1321 may be a motor. When the workpiece 200 needs to be rotated, the clamp 120 and the workpiece 200 may be lifted by the lifting assembly 131, and the protrusion 1212 may be separated from the clamp during the lifting of the clamp 120 and the workpiece 200. The clamp is then clamped to the boss 1212. Then, the second driving device 1321 is controlled to operate, the motor shaft can drive the clamping member to rotate, the clamping member 120 and the workpiece 200 can rotate together with the clamping member because the clamping member is fixed relative to the protruding portion 1212, and the elevating portion 1211 can be separated from the supporting member 1312 during the rotation of the clamping member 120 and the workpiece 200.

From this, through setting up above-mentioned setting, can realize the autogiration of anchor clamps 120 and work piece 200 to can carry out all-round processing (for example welding) to work piece 200, when satisfying the processing requirement of work piece 200, can need not artifical rotatory work piece 200, and then can reduce operating personnel's intensity of labour, improve the production efficiency of work piece 200. Moreover, the whole fixture 120 and the workpiece 200 can be driven to rotate by matching the protrusion 1212 with the clamping piece, the base 121 does not need to be directly matched with the clamping piece, the structural design of the base 121 can be simpler, and the overall layout is more reasonable.

In an alternative embodiment, each of the gantry 133, the lifting assembly 131 and the rotating assembly 132 is at least one pair, two gantries 133 in each pair are spaced apart, the fixture 120 and the workpiece 200 are adapted to be disposed between the two gantries 133, the plurality of lifters 1211 are respectively supported on the supports 1312 of the two lifting assemblies 131 during lifting of the workpiece 200, and the two protrusions 1212 are respectively clamped to the clamping members of the two rotating assemblies 132 during rotation of the workpiece 200.

With such an arrangement, during the lifting of the workpiece, each pair of supporting members 1312 can respectively support the lifting portions 1211 at the two ends of the base 121, so that the stress on the base 121 is more balanced, and the lifting of the workpiece 200 is more stable and is not easy to shake; in the rotation process of the workpiece 200, the two clamping members can respectively clamp the protrusions 1212 at the two ends of the base 121, so that the base 121 is stressed more evenly, and is not prone to shaking in the rotation process.

In one embodiment, at least one of the second drive devices 1321 of each pair of rotary assemblies 132 is operated during rotation of the workpiece 200.

In one example, one of each pair of second drives 1321 is operated during rotation of the workpiece 200. One of the two second driving devices 1321 is a driving device, and the other of the two second driving devices 1321 is a driven device. The driving device can drive the clamp 120 and the workpiece 200 to rotate through the corresponding clamping pieces, and since the two clamping pieces clamp the protruding portion 1212, the workpiece 200 fixed with the clamp 120 can drive the other clamping piece and the driven driving device to rotate. In this way, the power consumption can be reduced, the service life of the second driving device 1321 can be extended, and the cost can be reduced.

Of course, the present application is not limited thereto, and in another example, both of the second driving devices 1321 are operated during the rotation of the workpiece 200. By such arrangement, the base 121 can be stressed more uniformly, the driving force required to be provided by each driving device is reduced, and the rotation of the workpiece 200 is more reliable.

In one embodiment, as shown in fig. 10 and 11, the second driving device 1321 may be a motor including a motor body fixed to the gantry 133 and a motor shaft. The rotating assembly 132 further includes a fixing plate 1324, the fixing plate 1324 is fixedly connected to a motor shaft, the clamping member is disposed on one side of the fixing plate 1324 away from the motor body, and the motor shaft drives the workpiece 200 to rotate through the fixing plate 1324.

Illustratively, the motor shaft may extend from one side of the motor body. The fixing plate 1324 is located between the motor body and the holder. In the case where the workpiece 200 needs to be rotated, the clamp portion 1323 is in the clamping position. The motor shaft rotates the fixing plate 1324, and the clamping member is fixed to the fixing plate 1324, so that the clamping member can rotate together with the fixing plate 1324. Since the workpiece 200 is fixed relative to the clamping member, the workpiece 200 can be driven by the clamping member to rotate together.

Therefore, by arranging the fixing plate 1324, the mounting position can be provided for the clamping part, firm fixing of the clamping part is achieved, and the motor shaft can drive the clamping part and the workpiece 200 to rotate through the fixing plate 1324, so that the motor shaft can be directly connected with the clamping part without being connected with the clamping part, the mounting difficulty can be reduced while normal rotation of the workpiece 200 is guaranteed, and the structure of the whole gantry crane 130 is simpler.

In one embodiment, referring to fig. 10, the clamp includes at least one second actuator 1322 and at least two clamp portions 1323. For example, in the example of fig. 10, two second drivers 1322 and four clamping portions 1323 are shown, the four clamping portions 1323 constituting two clamping groups, each clamping group including two clamping portions 1323. At least one gripping portion 1323 of each gripping group is a moving gripping portion that is connected to a corresponding second actuator 1322. In the event that the workpiece needs to be rotated, the workpiece 200 may be raised by the lift assembly 131 to a position adjacent to the clamp portions 1323, and then the corresponding moving clamp portions are controlled to move by the second actuator 1322, such that the two clamp portions 1323 of each clamp group clamp the workpiece. And then the second driving device 1321 is controlled to work, so that the second driving device 1321 drives the second driver 1322, the clamping piece, the clamp 120 and the workpiece 200 to rotate together.

Therefore, by arranging the second driver 1322 and the clamping portion 1323, the second driver 1322 can provide driving force for the corresponding clamping portion 1323, so that the clamping portion 1323 can automatically move, and the moving direction of the clamping portion 1323 can be changed by changing the rotating direction of the second driver 1322, so that the clamping portion 1323 can be effectively controlled to clamp the workpiece 200 or loosen the workpiece 200, the operation is more convenient, and the reliability is higher.

In an alternative embodiment, referring to fig. 10, the two clamping portions 1323 may be opposed to each other in the up-down direction, and the two clamping portions 1323 clamp the upper surface and the lower surface of the workpiece 200 with the clamping portions 1323 in the clamping position, respectively.

Here, the "upper surface of the workpiece 200" may be understood as the upper surface of the workpiece 200 before the workpiece 200 is rotated, and similarly, the "lower surface of the workpiece 200" may be understood as the lower surface of the workpiece 200 before the workpiece 200 is rotated. It is understood that the "upper surface of the workpiece 200" and the "lower surface of the workpiece 200" may be rotated to other directions during the rotation of the workpiece 200.

Therefore, by the arrangement, the two side surfaces of the workpiece 200 in the thickness direction can be clamped, so that the workpiece 200 can be clamped more firmly while the operation is facilitated, and the clamping part 1323 and the workpiece 200 are prevented from moving relatively, so that the rotation of the workpiece 200 is safer and more reliable.

In one embodiment, with the workpiece 200 in the lift mode, the lift assembly 131 is connected to the workpiece 200 and the rotation assembly 132 is disconnected from the workpiece 200; with the workpiece 200 in the rotation mode, the rotation assembly 132 is connected to the workpiece 200, and the lift assembly 131 is disconnected from the workpiece 200.

Illustratively, the elevator 1211 can be supported on the support 1312 with the projection 1212 disengaged from the clamp in the case of the workpiece 200 in the elevator mode, and with the projection 1212 engaged with the clamp and the elevator 1211 disengaged from the support 1312 in the case of the workpiece 200 in the rotation mode.

In this way, the lifting process and the rotating process of the workpiece 200 can be independent of each other, and the interference of the rotating assembly 132 with the lifting of the workpiece 200 or the interference of the lifting assembly 131 with the rotation of the workpiece 200 can be avoided, so that the lifting and the rotation of the workpiece 200 can be more reliable.

In one embodiment, as shown in fig. 5 to 8, at least one limiting portion 1213 is provided on the outer circumferential side of the base 121, and the limiting portion 1213 is used to limit the movement of the gripper 120 in the direction offset from the conveying direction of the first conveying member 111.

One of the two limiting groups is disposed on the outer side surface of the first side, and the other of the two limiting groups is disposed on the outer side surface of the second side. Two of the limiting portions 1213 in each limiting group are located at two ends of the corresponding first edge or second edge, respectively, and the other limiting portion 1213 in each limiting group is located in the middle of the corresponding first edge or second edge.

Like this, spacing portion 1213 can play effectual positioning action, avoids base 121 to produce the skew for the direction of motion of transmission track to can avoid base 121 to drive work piece 200 and shift, guarantee in the motion process of first transport piece 111, base 121 and work piece 200 can be driven under first transport piece 111 along the direction of delivery transmission between each process, can promote the production reliability of work piece 200.

For example, two second conveying track assemblies 140 are shown in the example of fig. 1 and 13, and the two second conveying track assemblies 140 are respectively located at two sides of the first conveying track assembly 110 in the width direction, so that the length of the conveying track 112 assembly can be prevented from being too long, and the space size of the production line layout can be saved. Alternatively, the upper surface of the first conveyor rail assembly 110 may be coplanar with the upper surface of the second conveyor rail assembly 140 to facilitate transfer of the gripper 120 and the workpiece 200 from one of the first conveyor rail assembly 110 and the second conveyor rail assembly 140 to the other.

Therefore, the third conveying track assembly 150 can improve the flexibility of the production process, improve the bearing space of the whole assembly line, and further improve the fault tolerance of the track 112, and the third conveying track assembly 150 can also supply the storage of the returned semi-finished products, so that unqualified workpieces are temporarily placed in the third conveying track assembly 150, thereby finishing the rectification of the workpieces, realizing the process detection of the semi-finished products, and the like.

In an alternative embodiment, as shown in fig. 1, the conveying direction of the third conveying member 151 and the conveying direction of the first conveying member 111 may be the same.
