Fig. 1 illustrates a partial perspective view of a railway urinal soil box welding manufacturing line 100 according to an embodiment of the present application.

As shown in fig. 1, the railway urinal waste box welding manufacturing line 100 includes a first conveyor rail assembly 110, a clamp 120, and at least one gantry elevator 130. Specifically, the first conveyor track assembly 110 includes at least one first conveyor 111 that is movable. The clamp 120 includes a base 121 and at least one clamping assembly 122 disposed on the base 121, the first transport member 111 for carrying the base 121 to transport the clamp 120, the clamping assembly 122 for clamping the workpiece 200, such as for fixedly clamping an unwelded dirt box assembly. The gantry lifter 130 includes a lifting assembly 131 for controlling lifting of the workpiece 200, and a rotating assembly 132 for controlling rotation of the workpiece 200.

For example, in connection with fig. 13, the first transport 111 may move the clamp 120 and the workpiece 200, such as a dirt box, between processes, e.g., the first transport 111 may move the clamp 120 and the workpiece 200 in a first direction (e.g., forward and backward). In the process line for welding the contaminant box, the left end of the first conveying rail assembly 110 is defined as a first process of the process for welding the contaminant box, the clamp 120 is initially placed on the first conveying rail assembly 110, the clamping of the workpiece is performed on the first process, after the clamping of all the workpieces is completed, the first conveying member 111 is controlled to drive the clamp 120 and the workpiece to move, and the second process is performed until the whole welding of the workpiece 200 such as the contaminant box is completed, and the process line for welding the contaminant box can be realized by the movement of the first conveying member 111 without depending on any transmission operation between auxiliary processes of equipment outside the production line.

Wherein the assembled workpiece 200 is a dirt box. The clamping assembly 122 may be plural, and the plural clamping assemblies 122 are provided at the end of the base 121 to form a first receiving space for surrounding the workpiece between the plural clamping assemblies 122. That is, the front projection of the first accommodation space on the base 121 covers the front projection of the workpiece 200 on the base 121, and the plurality of clamping assemblies 122 are located at the outer circumference of the workpiece 200 in the state that the workpiece is clamped by the plurality of clamping assemblies 122.

For example, in the example of fig. 5-8, four clamping assemblies 122 are shown, the base 121 being generally rectangular parallelepiped in configuration, the four clamping assemblies 122 being disposed adjacent four corners of the base 121, respectively. Each clamping assembly 122 is movable between a clamping position to clamp the workpiece 200 and a unclamping position to unclamp the workpiece 200, with the clamping assembly 122 in the clamping position, the workpiece 200 is clamped by the four clamping assemblies 122, and the four clamping assemblies 122 are located at respective corners of the workpiece 200. In welding the workpiece 200, the welding robot 160 may be located at the middle of the workpiece 200, with a large working space.

Here, it should be noted that the "middle portion of the workpiece 200" is to be understood in a broad sense in the present application, and refers to a portion closer to the center of the workpiece 200 than the corners of the workpiece 200, and is not limited to the center of the workpiece 200.

Moreover, the generalization of the fixture 120 can be realized, the interference between the clamping assembly 122 and other structures in the production process of the workpiece 200 can be avoided, the one-time clamping of the workpiece 200 in the whole production process such as the welding process is realized, the repeated replacement of the fixture 120 is avoided, the labor intensity of operators can be reduced while the cost is reduced, the production efficiency is improved, and the potential safety hazard generated in the repeated clamping process is avoided.

Four clamping assemblies 122 are shown in fig. 5-8 for illustrative purposes, but it will be apparent to one of ordinary skill in the art after reading this disclosure that it is within the scope of the present disclosure to apply this disclosure to other numbers of clamping assemblies 122.

According to the railway toilet soil box welding manufacturing production line 100 provided by the embodiment of the application, by arranging the first conveying rail assembly 110, the clamp 120 and the gantry lifter 130, the first conveying member 111 can realize automatic transmission of the clamp 120 and the workpiece 200 among various procedures, so that large-scale equipment such as a forklift and a crane is not needed, the operation process is simple, stations of operators can be distributed on two sides of the first conveying rail assembly 110, the problem of mixing of people and goods can be solved, the separation of people and goods in the production process of the workpiece 200 is realized, and the safety can be greatly improved while the production efficiency is improved.

The control switch may be a control button provided on the workstation, but is not limited thereto.

Therefore, through the arrangement of the first driver and the driving part, the movement of the first conveying part 111 can be realized, so that the first conveying part 111 can drive the clamp 120 and the workpiece 200 to move, automatic transmission of the clamp 120 and the workpiece 200 between various procedures is realized, manual operation can be omitted, manpower is effectively saved, potential safety hazards are reduced, and in addition, the transmission direction of the clamp 120 and the workpiece 200 can be controlled by controlling the rotation direction of the first driver, so that the operation is very convenient.

In an alternative embodiment, as shown in fig. 1 and 3, the driving member comprises at least one chain; the first conveying members 111 are arranged in parallel at intervals, gears matched with the chains are arranged at corresponding ends of the first conveying members 111, and the first driver drives at least part of the first conveying members 111 to rotate through the chains so as to drive the clamp 120 to move.

Illustratively, the first conveying track assembly 110 may include two tracks 112 disposed in parallel spaced apart relation, with each first conveying member 111 pivotally connected at both ends to the two tracks 112, respectively. One end of the first conveying member 111 may be provided with two gears, the chain may be plural, and the gears of every adjacent two of the first conveying members 111 may be engaged with the same chain. The first conveying member 111 may have a shaft-like structure, and may drive the jig 120 and the workpiece 200 to move along the length direction of the rail 112 when the first conveying member 111 in contact with the base 121 rotates. Alternatively, the first driver may be a motor, but is not limited thereto.

Thus, by providing the chain and gear described above, the structure of the first conveying rail assembly 110 is made simpler, versatility and reliability are higher, and transmission efficiency is higher while conveying the jig 120 and the workpiece 200 is achieved.

In one embodiment, as shown in fig. 1, 2 and 9-11, the lifting assembly 131 includes a first driving device 1311 and a support 1312 coupled to each other; at least one lifting portion 1211 is provided on the base 121, and when the workpiece 200 is in the lifting mode, the lifting portion 1211 is supported on the support 1312, and the first driving device 1311 drives the jig 120 and the workpiece to lift together through the support 1312.

Illustratively, the first driving device 1311 may be a cylinder, the first driving device 1311 may include a cylinder body, a piston disposed in the cylinder body, and a piston rod fixedly connected to the piston and extending out of the cylinder body, and the support 1312 may be connected to the piston rod. The lifting portion 1211 is provided on the upper surface of the base 121, and a coupling groove may be defined between the lifting portion 1211 and the base 121, and when the workpiece 200 is in the lifting mode, the lifting portion 1211 may overlap the support 1312 such that the support 1312 is coupled in the coupling groove. The piston rod can stretch and retract relative to the cylinder body, so that the supporting piece 1312 is driven to lift, and the clamp 120 and the workpiece 200 are driven by the supporting piece 1312 to lift.

Therefore, the supporting piece 1312 can be contacted with the lifting part 1211 to drive the whole clamp 120 and the workpiece 200 to lift, the base 121 can be directly matched with the supporting piece 1312, the structural design of the base 121 can be simpler, and the overall layout is more reasonable.

In an alternative embodiment, referring to fig. 2 and fig. 5 to 7, the lifting units 1211 may be multiple, the lifting units 1211 are respectively located at corners of the base 121, and the plurality of clamping assemblies 122 are located in the accommodating space defined by the lifting units 1211. In the description of the present application, "plurality" means two or more.

So arranged, during the lifting process of the fixture 120 and the workpiece 200, the first driving device 1311 lifts the fixture 120 and the workpiece 200 more easily through the supporting member 1312, and the lifting portion 1211 at the corner can avoid occupying the space in the middle of the base 121, so as to play an effective role in avoiding interference with the workpiece 200 and other structural members.

In one example, the number of elevating portions 1211 is four, and the four elevating portions 1211 are provided at four corners of the base 121, respectively. The base 121 includes a frame 1215 and two support bars 1214. The frame 1215 may include first and second sides opposite to each other, and third and fourth sides opposite to each other. Wherein the first and second sides are long sides of the frame 1215, and the third and fourth sides are short sides of the frame 1215. The two support rods 1214 are a first rod and a second rod, respectively, the first rod having a length greater than the second rod. The first pole is established on first limit, and the one end of first pole is parallel and level with the outside surface of first limit to reduce occupation space, and the other end of first pole inwards extends, and the second pole is established on the second limit, and the one end of second pole is parallel and level with the outside surface of second limit, in order to reduce occupation space, the other end of second pole inwards extends, and the aforesaid other end of second pole and the aforesaid other end of first pole are relative each other.

Here, it should be noted that the direction "in" is understood as a direction toward the center of the base 121, and the opposite direction is defined as "out", i.e., a direction away from the center of the base 121.

Through setting up frame 1215 and a plurality of bracing piece 1214 above-mentioned, base 121 can be hollow structure to can reduce the weight of whole anchor clamps 120, reduce cost, and the well effect of dodging can be played to the well portion of base 121, avoid producing the interference with other structures, simultaneously, a plurality of bracing pieces 1214 can play better supporting role to work piece 200, promote the clamping stability of work piece 200.

In one embodiment, referring to fig. 9 and 11, the gantry crane 130 further includes a gantry 133, the gantry 133 includes a first connecting rod 1331 and two second connecting rods 1332, two ends of the first connecting rod 1331 are respectively connected to top ends of the two second connecting rods 1332, and the first conveying track assembly 110 is disposed between the two second connecting rods 1332 in a penetrating manner; the supporting member 1312 is a supporting rod, which is parallel to the first connecting rod 1331.

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

Thus, by making the support 1312 a support bar, the size of the support 1312 is relatively small, so that the occupied space can be reduced and the arrangement is more convenient while effectively supporting the workpiece 200. By making the support bar parallel to the first connecting bar 1331, it is ensured that the workpiece 200 can be maintained in a horizontal state under the support of the support bar 1214 in the case that the workpiece 200 is in a 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.

Further, referring to fig. 9 and 11, the first connecting rod 1331 and the two second connecting rods 1332 together define a through hole through which the support piece 1312 protrudes. For example, in the example of fig. 9 and 11, one end of the support 1312 is connected to a mounting bar and the other end of the support 1312 extends inwardly such that an orthographic projection of the other end of the support 1312 onto the through-opening covers a portion of the through-opening.

Thus, the length of the support 1312 is relatively long, so that the contact area of the support 1312 and the lifting portion 1211 can be increased, the support reliability of the support 1312 can be improved, potential safety hazards caused by the fact that the lifting portion 1211 is disengaged from the support 1312 during lifting of the workpiece 200 can be avoided, the pressure can be reduced, deformation and damage of the support 1312 or the lifting portion 1211 can be avoided, and the structural reliability of the support 1312 and the clamp 120 can be improved.

In one embodiment, as shown in fig. 5 and 10, the rotating assembly 132 includes a second driving device 1321 and a clamping member connected to each other; the base 121 is provided with at least one protrusion 1212 on a side thereof, the protrusion 1212 being engaged with a clamp by which the second driving means 1321 drives the clamp 120 and the workpiece 200 to co-rotate with each other in the rotated mode of the workpiece 200.

For example, the number of the protrusions 1212 may be two, the two protrusions 1212 are located at the sides of the third and fourth sides, respectively, and the two protrusions 1212 protrude in directions away from each other, respectively. The second driving device 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 protrusions 1212 may be separated from the clamp during lifting of the clamp 120 and the workpiece 200. The clamp then grips the boss 1212. Then, the second driving device 1321 is controlled to operate, and the motor shaft may rotate the clamping member, so that the clamping member and the protrusion 1212 are relatively fixed, the clamp 120 and the workpiece 200 may rotate together with the clamping member, and the lifting portion 1211 may be separated from the supporting member 1312 during the rotation of the clamp 120 and the workpiece 200.

Therefore, by arranging the above arrangement, the automatic rotation of the clamp 120 and the workpiece 200 can be realized, so that the workpiece 200 can be processed (for example, welded) in all directions, the workpiece 200 can be rotated without manpower while the processing requirement of the workpiece 200 is met, the labor intensity of operators can be reduced, and the production efficiency of the workpiece 200 is improved. Moreover, the whole clamp 120 and the workpiece 200 can be driven to rotate by the cooperation of the convex portion 1212 and the clamping piece, the base 121 can 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, the gantry 133, the lifting assembly 131 and the rotating assembly 132 are at least one pair, and the two gantry 133 in each pair are spaced apart, and the fixture 120 and the workpiece 200 are adapted to be disposed between the two gantry 133, and the plurality of lifting portions 1211 are respectively supported on the supporting members 1312 of the two lifting assemblies 131 during lifting of the workpiece 200, and the two protruding portions 1212 are respectively clamped to the clamping members of the two rotating assemblies 132 during rotation of the workpiece 200.

In this way, during the lifting process of the workpiece, each pair of supporting pieces 1312 can respectively support the lifting parts 1211 at two ends of the base 121, so that the stress of 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 pieces can respectively clamp the convex portions 1212 at two ends of the base 121, so that the stress of the base 121 can be balanced, and shaking is not easy to generate in the rotation process.

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

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

Of course, the application is not so limited, and in another example, both second drive devices 1321 are operated during rotation of the workpiece 200. By this arrangement, the stress of the base 121 can be more uniform, the driving force required to be provided by each driving device can be reduced, and the rotation of the workpiece 200 can be 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 and a motor shaft, and the motor body is fixed to the gantry 133. The rotating assembly 132 further includes a fixing plate 1324, the fixing plate 1324 is fixedly connected with a motor shaft, the clamping member is disposed on one side of the fixing plate 1324 far away from the motor body, and the motor shaft drives the workpiece 200 to rotate through the fixing plate 1324.

For example, the motor shaft may protrude from one side of the motor body. A fixed plate 1324 is located between the motor body and the clamping member. In the event that the workpiece 200 needs to be rotated, the clamping portion 1323 is in the clamping position. The motor shaft rotates the fixed plate 1324, and the clamping member can rotate together with the fixed plate 1324 because the clamping member is fixed to the fixed plate 1324. Because the workpiece 200 and the clamping piece are relatively fixed, the workpiece 200 can be driven by the clamping piece to rotate together.

Therefore, by arranging the fixing plate 1324, the mounting position can be provided for the clamping piece, firm fixing of the clamping piece is realized, and the motor shaft can drive the clamping piece and the workpiece 200 to rotate through the fixing plate 1324, so that the motor shaft can be directly connected with the clamping piece, the mounting difficulty can be reduced while the normal rotation of the workpiece 200 is ensured, 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 driver 1322 and at least two clamps 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 comprising two clamping portions 1323. At least one clamping portion 1323 of each clamping group is a moving clamping portion, which is connected to a corresponding second driver 1322. In the case that the workpiece needs to be rotated, the workpiece 200 may be lifted up to a position adjacent to the clamping portions 1323 by the lifting assembly 131, and then the corresponding moving clamping portions are controlled to move by the second driver 1322, so that the two clamping portions 1323 of each clamping group clamp the workpiece. Then, the second driving device 1321 is controlled to operate, so that the second driving device 1321 drives the second driver 1322, the clamping member, the clamp 120 and the workpiece 200 to rotate together.

Therefore, by providing 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 or unclamp the workpiece 200, the operation is more convenient, and the reliability is higher.

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

Where "upper surface of the workpiece 200" may be understood as the upper surface of the workpiece 200 prior to rotation of the workpiece 200, and similarly "lower surface of the workpiece 200" may be understood as the lower surface of the workpiece 200 prior to rotation of the workpiece 200. It will be appreciated that during rotation of the workpiece 200, the "upper surface of the workpiece 200" and the "lower surface of the workpiece 200" described above may be rotated to other directions.

Therefore, through the arrangement, the two side surfaces of the workpiece 200 in the thickness direction can be clamped, the workpiece 200 can be clamped more firmly while the operation is convenient, and the relative movement of the clamping part 1323 and the workpiece 200 is avoided, 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 lifting assembly 131 is disconnected from the workpiece 200.

Illustratively, the lifting portion 1211 may be supported on the support 1312 while the boss 1212 is disengaged from the clamp in the case where the workpiece 200 is in the lifting mode, the boss 1212 is engaged with the clamp while the lifting portion 1211 is disengaged from the support 1312 in the case where the workpiece 200 is in the rotation mode.

In this way, the lifting process and the rotating process of the workpiece 200 can be independent from each other, so that the rotation component 132 is prevented from interfering with the lifting of the workpiece 200 or the lifting component 131 is prevented from interfering with the rotation of the workpiece 200, and the lifting and the rotation of the workpiece 200 are more reliable.

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

For example, six limit portions 1213 are shown in the example of fig. 7, the six limit portions 1213 constituting two limit groups, each limit group including three limit portions 1213. One of the two limiting groups is arranged on the outer side surface of the first side, and the other one of the two limiting groups is arranged on the outer side surface of the second side. Wherein, two of the limiting portions 1213 in each limiting group are respectively positioned at two ends of the corresponding first side or second side, and the other limiting portion 1213 in each limiting group is positioned at the middle of the corresponding first side or second side.

Thus, the limiting portion 1213 can perform an effective positioning function, so that the base 121 is prevented from being offset relative to the movement direction of the transmission track, and therefore the base 121 can be prevented from driving the workpiece 200 to shift, the base 121 and the workpiece 200 can be ensured to be driven to drive between the working procedures along the conveying direction under the driving of the first conveying member 111 in the movement process of the first conveying member 111, and the production reliability of the workpiece 200 can be improved.

For example, in the examples of fig. 1 and 13, two second conveying rail assemblies 140 are shown, and the two second conveying rail assemblies 140 are respectively located at both sides of the first conveying rail assembly 110 in the width direction, so that the length of the conveying rail 112 assembly can be prevented from being excessively long, and thus the space size of the line layout production 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 clamp 120 and workpiece 200 from one of the first conveyor rail assembly 110 and the second conveyor rail assembly 140 to the other.

Therefore, the above-mentioned second conveying track assembly 140 cooperates with the first conveying track assembly 110 to effectively improve the fault tolerance of the track 112, for example, the second conveying track assembly 140 can supply and store the reflow semi-finished product, and temporarily line the unqualified workpiece from the first conveying track assembly 110 to the second conveying track assembly 140, so as to complete the modification of the workpiece 200 and realize the semi-finished product process detection.

The upper surface of the third conveyor rail assembly 150 can be coplanar with the upper surface of the second conveyor rail assembly 140 to facilitate transfer of the clamp 120 and workpiece 200 from one of the third conveyor rail assembly 150 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, promote the bearing space of the whole assembly line, further promote the fault tolerance of the track 112, and the third conveying track assembly 150 can also supply the storage of the reflow semi-finished product, and temporarily place unqualified workpieces to the third conveying track assembly 150 so as to finish the correction of the workpieces, realize the detection of the semi-finished product process, and the like.

In an alternative embodiment, as shown in fig. 1, the conveying direction of the third conveying member 151 may be the same as the conveying direction of the first conveying member 111. In this way, the third conveyor rail assembly 150 may be substantially parallel to the first conveyor rail assembly 110, so that the overall footprint of the first, second, and third conveyor rail assemblies 110, 140, 150 may be reduced while the load-bearing area of the assembly line is lifted, with a more rational layout.

Wherein at least one clamping portion of each clamping assembly 122 presses against the upper surface of the workpiece 200, and at least two clamping portions of each clamping assembly 122 respectively clamp adjacent two sides of the workpiece 200.

Therefore, through the arrangement, the plurality of clamping parts can stably clamp the workpiece 200, and the influence on the operation of the workpiece 200 caused by the shaking of the workpiece 200 is avoided, so that the production process of the workpiece 200 is more reliable.
