One side of the first rotating component is connected to the clamping assembly, and the other side of the first rotating component abuts against a first side of the tailstock assembly. The output end of the driving assembly is coaxially arranged with the first rotating component and is connected to a second side of the tailstock assembly. The clamping assembly can drive the first rotating component to move along its own axis, so that the first rotating component moves closer to or away from the driving assembly.

Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically, to a welding workstation. Background Technology

[0002] Currently, in related technologies, the rear seat of a mining dump truck consists of three parts: a first rear seat, a second rear seat, and an intermediate cylinder. The rear seat assembly of a mining dump truck withstands high torque, periodic impacts, and complex stresses. Therefore, the two rear seats need to be welded to both ends of the intermediate cylinder. Typically, two circumferential welds are manually welded to connect the first and second rear seats to the intermediate cylinder as a single unit. Due to the large size of the rear seat assembly, welding can only be performed around the weld seams using overhead or vertical welding methods. This method is inefficient and results in low production efficiency. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the present invention proposes a welding workstation.

[0005] In view of this, a first aspect of the present invention provides a welding workstation for welding a tailstock assembly having an circumferential weld. The welding workstation includes a clamping assembly, a first rotating component, and a driving assembly. One side of the first rotating component is connected to the clamping assembly, and the other side of the first rotating component is used to abut against a first side of the tailstock assembly. The output end of the driving assembly is coaxially arranged with the first rotating component, and the output end of the driving assembly is used to connect to a second side of the tailstock assembly. The clamping assembly can drive the first rotating component to move along its own axis, so that the first rotating component moves closer to or away from the driving assembly. When the tailstock assembly is clamped between the first rotating component and the output end of the driving assembly, the output end of the driving assembly can drive the tailstock assembly to rotate around its own axis, thereby rotating the circumferential weld.

[0006] In this technical solution, the welding workstation includes a clamping assembly, a first rotating component, and a drive assembly. The welding workstation is used for welding the rear tail section of a mining dump truck, and the rear tail section assembly has an circumferential weld. During operation, the rear tail section assembly of the mining dump truck is subjected to high torque and periodic impact loads, resulting in complex stress. Therefore, the first and second tail sections need to be welded to both ends of the intermediate cylinder, respectively. The circumferential weld is where the first and second tail sections are welded to the intermediate cylinder, meaning that one rear tail section assembly has two circumferential welds.

[0007] The clamping assembly is used to clamp the rear tailstock assembly to achieve positioning and fixation of the rear tailstock assembly. One side of the first rotating component is connected to the clamping assembly, and the other side of the first rotating component is used to abut against the first side of the rear tailstock assembly, so that one end of the rear tailstock assembly abuts against the first rotating component, thereby supporting one end of the rear tailstock assembly. The output end of the drive assembly is coaxially arranged with the first rotating component, and the output end of the drive assembly is used to connect to the second side of the rear tailstock assembly, so that the other end of the rear tailstock assembly is connected to the output end of the drive assembly. By setting both ends of the rear tailstock assembly between the first rotating component and the drive assembly respectively, the rear tailstock assembly is clamped between the first rotating component and the output end of the drive assembly during the welding process, thereby achieving stable support and positioning of the rear tailstock assembly. Before clamping, both ends of the intermediate cylinder are pre-fixed to the corresponding tailstocks to facilitate clamping of the rear tailstock assembly. By driving the clamping assembly, the clamping and releasing of the rear tailstock assembly is achieved.

[0008] The clamping assembly drives the first rotating component to move along its own axis, allowing it to move closer to or away from the drive assembly. When clamping the tailstock assembly, the clamping assembly drives the first rotating component away from the drive assembly, increasing the distance between the first rotating component and the output end of the drive assembly, facilitating the placement of the tailstock assembly between them. After the tailstock assembly is in place, the clamping assembly drives the first rotating component closer to the drive assembly, causing it to abut against the first side of the tailstock assembly, thus clamping the tailstock assembly between the first rotating component and the output end of the drive assembly. By using the clamping assembly, tailstock assemblies of different lengths can be clamped, improving the versatility and adaptability of the welding workstation. Simultaneously, the clamping assembly maintains a clamped state on the tailstock assembly during welding, ensuring that the tailstock assembly does not experience axial movement or loosening during rotation, thus guaranteeing the stability and safety of the welding process.

[0009] With the rear tailstock assembly clamped between the first rotating component and the output end of the drive assembly, the output end of the drive assembly can drive the rear tailstock assembly to rotate around its own axis, thereby rotating the annular weld seam. Since the rear tailstock assembly is clamped between the first rotating component and the output end of the drive assembly, when the output end of the drive assembly rotates, the rear tailstock assembly rotates synchronously with the output end of the drive assembly, supported by the first rotating component. As the rear tailstock assembly rotates, the annular weld seam on the rear tailstock assembly rotates together, thus removing the annular weld seam from unfavorable positions such as overhead and vertical welding. This avoids operators performing welding operations in unfavorable positions, thereby reducing welding difficulty and improving welding efficiency.

[0010] The welding workstation of this invention, compared to the "related technology, where the large size and eccentric structure of the rear tailstock assembly make it difficult to rotate the workpiece during welding, forcing operators to perform all-position welding on the circumferential weld from a fixed position, inevitably requiring overhead and vertical welding operations. Overhead and vertical welding operations are difficult and limit welding speed, resulting in long welding times for a single weld," addresses this issue. This invention drives the rear tailstock assembly to rotate around its own axis using a drive component, moving the circumferential weld out of unfavorable overhead and vertical welding positions. Operators no longer need to weld in these positions, increasing welding speed, reducing labor intensity, and thus improving welding efficiency.

[0011] This invention, by clamping the rear tailstock assembly between the drive assembly and the first rotating component, and driving the rear tailstock assembly to rotate, removes the circumferential weld seam from unfavorable positions such as overhead and vertical welding. This avoids welding operations in unfavorable positions, increases welding speed, reduces labor intensity, and thus improves welding efficiency. Furthermore, by driving the first rotating component along its own axis, this invention can clamp rear tailstock assemblies of different lengths, improving the versatility and adaptability of the welding workstation.

[0012] Optionally, in some technical solutions of the present invention, the welding workstation further includes a first support component, which is arranged opposite to the drive component, and a clamping component is disposed on the first support component; a first rotating component is disposed on the first support component and is slidably connected to the first support component.

[0013] In this technical solution, the clamping assembly and the first rotating component are mounted and supported by a first supporting component. The first supporting component is arranged opposite to the drive assembly, the clamping assembly is mounted on the first supporting component, and the first rotating component is mounted on and slidably connected to the first supporting component. Driven by the clamping assembly, the first rotating component can slide relative to the first supporting component along its own axis, thereby moving closer to or further away from the drive assembly. The sliding motion of the first rotating component is guided and supported by the first supporting component, ensuring the motion accuracy and stability of the first rotating component during the sliding process, thus guaranteeing the reliability of the rear tailstock assembly clamping.

[0014] In some technical solutions of the present invention, optionally, the clamping assembly includes a second support member and a clamping member. One side of the second support member is connected to the first support member; the clamping member passes through the side of the second support member away from the first support member, and the clamping member is threadedly connected to the second support member. The clamping member is movable relative to the second support member to drive the first rotating member to move closer to or away from the driving assembly.

[0015] In this technical solution, the clamping assembly includes a second support component and a clamping component. One side of the second support component is connected to the first support component, providing support and fixation for the clamping assembly. The clamping component passes through the side of the second support component away from the first support component and is threadedly connected to the second support component. When the clamping component rotates relative to the second support component, due to the threaded engagement, the clamping component moves relative to the second support component along its own axis, thereby driving the first rotating component to move closer to or away from the driving component along its own axis. The movement of the clamping component through the threaded engagement with the second support component allows for clamping or releasing of the tailstock assembly. Simultaneously, the threaded connection has a self-locking function, maintaining the clamped state after clamping and ensuring the stability of the tailstock assembly during welding.

[0016] Optionally, in some technical solutions of the present invention, the welding workstation further includes a welding robot, which is used to weld the circumferential weld of the tailstock assembly.

[0017] In this technical solution, the welding workstation is also equipped with a welding robot. The welding robot is used for automated welding of the circumferential weld seam on the rear tailstock assembly. The welding robot has advantages such as high welding speed, stable welding quality, and continuous operation. By setting up the welding robot, automated welding of the circumferential weld seam can be achieved, replacing manual welding, thereby further improving welding efficiency, ensuring consistent welding quality, and reducing labor costs. Since the rear tailstock assembly has two circumferential weld seams, using robotic welding can weld both seams, ensuring welding quality while significantly improving production efficiency.

[0018] Optionally, in some technical solutions of the present invention, the welding workstation further includes a slide rail, which is arranged along the axial direction of the first rotating component and located on one side of the clamping component and the driving component. The welding robot is mounted on the slide rail and is able to slide relative to the slide rail.

[0019] In this technical solution, the welding workstation is also equipped with a slide rail. The slide rail is arranged along the axis of the first rotating component and is located on one side of the clamping assembly and the drive assembly. The welding robot is mounted on the slide rail and can slide relative to it. Because the tailstock assembly has an annular weld, the welding robot needs to move axially along the tailstock assembly to cover the entire weld during the tailstock assembly's rotation around its own axis. By mounting the welding robot on the slide rail, the welding robot can slide along the slide rail, thereby moving axially along the tailstock assembly to achieve continuous welding at various positions of the annular weld. The working range of the welding robot is expanded by the slide rail, enabling continuous automated welding of the annular weld, thereby improving welding efficiency and welding quality.

[0020] In some technical solutions of the present invention, optionally, the number of slide rails is two, and the two slide rails are arranged side by side.

[0021] In this technical solution, two parallel slide rails are used, and the welding robot slides simultaneously on both rails. The two slide rails jointly support and guide the welding robot, resulting in more balanced forces and smoother movement during sliding, thereby improving the robot's motion accuracy and ensuring welding quality.

[0022] Optionally, in some technical solutions of the present invention, the welding workstation further includes a controller, which is electrically connected to the welding robot and the drive assembly respectively. The controller is used to adjust the working state of the drive assembly, the displacement of the welding robot, and the welding position of the welding robot.

[0023] In this technical solution, the welding workstation is also equipped with a controller. The controller is electrically connected to both the welding robot and the drive assembly. The controller can send control signals to the drive assembly to control its start / stop, rotation direction, and rotation speed; the controller can also send control signals to the welding robot to control its displacement on the slide rail and the welding position of the welding torch. Through the controller's coordinated control of the drive assembly and the welding robot, the rotation of the drive assembly and the welding of the welding robot can be coordinated, that is, while the tailstock assembly rotates with the drive assembly, the welding robot continuously welds the circumferential weld. This coordinated control of the drive assembly and the welding robot enables automated continuous welding of the circumferential weld, significantly improving welding efficiency.

[0024] In some technical solutions of the present invention, optionally, the welding robot includes a third support component and a welding component. The third support component is slidably connected to a slide rail; the welding component is disposed on the third support component and is rotatable relative to the third support component.

[0025] In this technical solution, the welding robot includes a third support component and a welding component. The third support component is slidably connected to a slide rail, enabling the welding robot to slide on the slide rail. The welding component is mounted on the third support component and can rotate relative to it. During the welding process, the welding component can slide along the slide rail under the influence of the third support component, and simultaneously rotate relative to the third support component to adjust its posture, thereby achieving welding of the circumferential weld at different positions and angles. The rotation of the welding component relative to the third support component and the sliding of the third support component along the slide rail enhance the flexibility and adaptability of the welding process.

[0026] In some technical solutions of the present invention, optionally, the welding component includes a connecting segment and a welding torch. There are multiple connecting segments, which are connected end-to-end, with adjacent connecting segments rotatably connected; the welding torch is mounted on the connecting segment located at the end of the multiple connecting segments.

[0027] In this technical solution, the welding component consists of multiple connecting segments and a welding torch. The connecting segments are connected end-to-end, with adjacent segments rotating to form an articulated robotic arm structure. The connecting segments can rotate relative to each other, allowing the welding torch to move with multiple degrees of freedom in space. The welding torch is mounted on the end segment of the multiple connecting segments and can move to any position and angle under the influence of these segments. Through the relative rotation between the connecting segments, the welding torch's posture can be flexibly adjusted, enabling multi-angle and multi-position welding of circumferential welds, further improving welding flexibility and quality.

[0028] In some technical solutions of the present invention, optionally, the driving component includes a second rotating component and a driving component. The second rotating component includes the output end of the driving component; the driving component is connected to the second rotating component and is capable of driving the second rotating component to rotate relative to the driving component.

[0029] In this technical solution, the drive assembly includes a second rotating component and a drive component. The second rotating component includes an output end of the drive assembly for connection to a second side of the rear tailstock assembly. The drive component is connected to the second rotating component and provides driving force for the rotation of the rear tailstock assembly. When the drive component is working, it drives the second rotating component to rotate relative to the drive component. The second rotating component transmits power to the rear tailstock assembly through the output end of the drive assembly, thereby driving the rear tailstock assembly to rotate around its own axis. By driving the second rotating component to rotate through the drive component, reliable drive for the rotation of the rear tailstock assembly is achieved.

Detailed Implementation

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] The following reference Figures 1 to 3 A welding workstation 100 is described according to some embodiments of the present invention.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a welding workstation 100 for welding a tailstock assembly 200, the tailstock assembly 200 having an annular weld 208. The welding workstation 100 includes a clamping assembly 102, a first rotating component 108, and a drive assembly 110. One side of the first rotating component 108 is connected to the clamping assembly 102, and the other side of the first rotating component 108 is used to abut against a first side of the tailstock assembly 200. The output end of the drive assembly 110 is coaxially arranged with the first rotating component 108, and the output end of the drive assembly 110 is used to connect to a second side of the tailstock assembly 200. The clamping assembly 102 can drive the first rotating component 108 to move along its own axis, so that the first rotating component 108 moves closer to or away from the drive assembly 110. When the tailstock assembly 200 is clamped between the first rotating component 108 and the output end of the drive assembly 110, the output end of the drive assembly 110 can drive the tailstock assembly 200 to rotate around its own axis, thereby rotating the annular weld 208.

[0041] In this embodiment, the welding workstation 100 includes a clamping assembly 102, a first rotating component 108, and a drive assembly 110. The welding workstation 100 is used for welding the rear tail section of a mining dump truck, and the rear tail section assembly 200 has an annular weld 208. The rear tail section assembly 200 of the mining dump truck is subjected to large torque and periodic impact loads during operation, resulting in complex stress. Therefore, the first tail section 202 and the second tail section 204 need to be welded to both ends of the intermediate cylinder 206, respectively. The annular weld 208 is the position where the first tail section 202 and the second tail section 204 need to be welded to the intermediate cylinder 206, that is, a rear tail section assembly 200 has two annular welds 208.

[0042] The clamping assembly 102 is used to clamp the tailstock assembly 200 to position and fix the tailstock assembly 200. One side of the first rotating component 108 is connected to the clamping assembly 102, and the other side of the first rotating component 108 is used to abut against the first side of the tailstock assembly 200, so that one end of the tailstock assembly 200 abuts against the first rotating component 108, thereby supporting one end of the tailstock assembly 200. The output end of the drive assembly 110 is coaxially arranged with the first rotating component 108, and the output end of the drive assembly 110 is used to connect to the second side of the tailstock assembly 200, so that the other end of the tailstock assembly 200 is connected to the output end of the drive assembly 110. By positioning the two ends of the rear tailstock assembly 200 between the first rotating component 108 and the drive assembly 110, the rear tailstock assembly 200 is clamped between the output ends of the first rotating component 108 and the drive assembly 110 during the welding process, thereby achieving stable support and positioning of the rear tailstock assembly 200. Before clamping, the two ends of the intermediate cylinder 206 are pre-fixed to the corresponding tailstocks to facilitate clamping the rear tailstock assembly 200. The clamping and releasing of the rear tailstock assembly 200 is achieved by driving the clamping assembly 102.

[0043] The clamping assembly 102 can drive the first rotating component 108 to move along its own axis, so that the first rotating component 108 moves closer to or away from the drive assembly 110. When it is necessary to clamp the tailstock assembly 200, the clamping assembly 102 drives the first rotating component 108 away from the drive assembly 110, increasing the distance between the first rotating component 108 and the output end of the drive assembly 110, so as to facilitate the placement of the tailstock assembly 200 between the first rotating component 108 and the output end of the drive assembly 110; after the tailstock assembly 200 is placed in place, the clamping assembly 102 drives the first rotating component 108 closer to the drive assembly 110, so that the first rotating component 108 abuts against the first side of the tailstock assembly 200, thereby clamping the tailstock assembly 200 between the first rotating component 108 and the output end of the drive assembly 110. By setting the clamping assembly 102, tailstock assemblies 200 of different lengths can be clamped, thereby improving the versatility and adaptability of the welding workstation 100. Meanwhile, the clamping assembly 102 maintains a clamped state on the tailstock assembly 200 during the welding process, ensuring that the tailstock assembly 200 will not move axially or loosen during rotation, thereby ensuring the stability and safety of the welding process.

[0044] With the rear tailstock assembly 200 clamped between the first rotating component 108 and the output end of the drive assembly 110, the output end of the drive assembly 110 can drive the rear tailstock assembly 200 to rotate around its own axis, thereby rotating the annular weld seam 208. Since the rear tailstock assembly 200 is clamped between the first rotating component 108 and the output end of the drive assembly 110, when the output end of the drive assembly 110 rotates, the rear tailstock assembly 200 rotates synchronously with the output end of the drive assembly 110, supported by the first rotating component 108. When the rear tailstock assembly 200 rotates, the annular weld seam 208 on the rear tailstock assembly 200 rotates together, thereby removing the annular weld seam 208 from unfavorable positions such as overhead welding and vertical welding, avoiding welding operations by operators in unfavorable positions, thus reducing welding difficulty and improving welding efficiency.

[0045] The welding workstation 100 of this invention, compared to the "related art, due to the large size and eccentric structure of the rear tailstock assembly, the workpiece is difficult to rotate during welding, and the operator can only perform all-position welding on the circumferential weld in a fixed position. This inevitably requires operations in unfavorable positions such as overhead and vertical welding. Overhead and vertical welding positions are difficult to operate, and welding speed is limited, resulting in long welding times for a single weld," addresses this issue. The invention uses a drive component 110 to drive the rear tailstock assembly 200 to rotate around its own axis, moving the circumferential weld 208 out of unfavorable positions such as overhead and vertical welding. This eliminates the need for the operator to weld in these unfavorable positions, increasing welding speed, reducing labor intensity, and thus improving welding efficiency.

[0046] This invention, by clamping the tailstock assembly 200 between the drive assembly 110 and the first rotating component 108, and driving the tailstock assembly 200 to rotate via the drive assembly 110, removes the circumferential weld 208 from unfavorable positions such as overhead and vertical welding. This avoids welding operations in unfavorable positions, increases welding speed, reduces labor intensity, and thus improves welding efficiency. Simultaneously, by driving the first rotating component 108 along its own axis via the clamping assembly 102, this invention can clamp tailstock assemblies 200 of different lengths, improving the versatility and adaptability of the welding workstation 100.

[0047] Specifically, in Figure 1 In the diagram, A represents the axial direction of the first rotating component 108, and B represents the axial direction of the rear tail assembly 200.

[0048] Specifically, the drive assembly 110 is a positioner, which can drive the rear tailstock assembly 200 to rotate, thereby driving the rear tailstock assembly 200 to rotate in the opposite direction.

[0049] Specifically, the present invention designs a positioner that can flip the tailstock assembly 200, so that the tailstock can rotate 360° with the active end after being clamped on the positioner. This can transform the circumferential weld 208 into a horizontal hull-shaped weld, avoiding unfavorable welding positions such as overhead welding and vertical welding, and significantly reducing welding defects.

[0050] Specifically, the rotation refers to the output of the drive assembly 110 driving the stern assembly 200 to rotate continuously 360° around its own axis. The horizontal hull position refers to the position where the section to be welded of the annular weld 208 is horizontal along the weld axis and the weld is facing upwards. By switching the annular weld 208 to the welding position segment by segment for welding, problems such as molten pool sagging in the overhead welding position and molten pool flowing in the vertical welding position are avoided.

[0051] In some embodiments of the present invention, optionally, such as Figure 1 , Figure 2 and Figure 3 As shown, the welding workstation 100 also includes a first support component 116, which is arranged opposite to the drive assembly 110. The clamping assembly 102 is disposed on the first support component 116. The first rotating component 108 is disposed on the first support component 116 and is slidably connected to the first support component 116.

[0052] In this embodiment, the clamping assembly 102 and the first rotating component 108 are mounted and supported by the first support component 116. The first support component 116 is arranged opposite to the drive assembly 110. The clamping assembly 102 is disposed on the first support component 116, and the first rotating component 108 is disposed on the first support component 116 and slidably connected to it. The first rotating component 108 can slide relative to the first support component 116 along its own axis under the drive of the clamping assembly 102, thereby moving closer to or away from the drive assembly 110. The sliding movement of the first rotating component 108 is guided and supported by the first support component 116, ensuring the movement accuracy and stability of the first rotating component 108 during the sliding process, thereby ensuring the reliability of the rear tailstock assembly 200 clamping.

[0053] Specifically, the first rotating component 108 is a rotating disk. The rotating disk is mounted on the first supporting component 116 via a bearing seat and is slidably connected to the first supporting component 116. The bearing seat is slidably disposed on the first supporting component 116, and the rotating disk is mounted on the bearing seat via a bearing, allowing the rotating disk to rotate freely around its own axis. At the same time, a slider or slide block is correspondingly disposed at the bottom of the bearing seat, and a groove or guide rail is correspondingly disposed on the first supporting component 116 along its own length direction. The slider or slide block is embedded in the groove or guide rail, so that the bearing seat and the rotating disk, as a whole, can reciprocate along the first supporting component 116 under the drive of the clamping assembly 102.

[0054] In other words, through the bearing housing, the rotating disk can both rotate freely around its own axis and slide along the first support member 116 under the drive of the clamping assembly 102. When the tailstock assembly 200 needs to be clamped, the clamping assembly 102 drives the bearing housing to slide along the first support member 116. The bearing housing drives the rotating disk away from the drive assembly 110, increasing the distance between the rotating disk and the output end of the drive assembly 110, so as to facilitate the placement of the tailstock assembly 200 between the rotating disk and the output end of the drive assembly 110. After the tailstock assembly 200 is in place, the clamping assembly 102 drives the bearing housing to slide in the opposite direction along the first support member 116. The bearing housing drives the rotating disk closer to the drive assembly 110, so that the rotating disk abuts against the first side of the tailstock assembly 200, thereby clamping the tailstock assembly 200 between the rotating disk and the output end of the drive assembly 110. The rotating disk achieves both free rotation around its own axis and sliding along the first support member 116 through the bearing housing.

[0055] Specifically, the first rotating component 108 is provided with a first positioning component on the side opposite to the clamping assembly 102. The first positioning component is used to be embedded in the end of the tailstock assembly 200 to achieve radial positioning of the tailstock assembly 200.

[0056] Specifically, the first positioning component is a positioning protrusion, which is embedded in the central hole at the end of the tailstock assembly 200 to achieve radial positioning of the tailstock assembly 200.

[0057] In some embodiments of the present invention, optionally, such as Figure 1 As shown, the clamping assembly 102 includes a second support member 104 and a clamping member 106. One side of the second support member 104 is connected to the first support member 116; the clamping member 106 passes through the side of the second support member 104 away from the first support member 116, and the clamping member 106 is threadedly connected to the second support member 104. The clamping member 106 can move relative to the second support member 104 to drive the first rotating member 108 to move closer to or away from the driving assembly 110.

[0058] In this embodiment, the clamping assembly 102 includes a second support member 104 and a clamping member 106. One side of the second support member 104 is connected to the first support member 116, providing support and fixation for the clamping assembly 102. The clamping member 106 passes through the side of the second support member 104 away from the first support member 116, and is threadedly connected to the second support member 104. When the clamping member 106 rotates relative to the second support member 104, due to the threaded engagement, the clamping member 106 moves relative to the second support member 104 along its own axis, thereby driving the first rotating member 108 to move closer to or away from the driving assembly 110 along its own axis. The movement of the clamping member 106 through the threaded engagement with the second support member 104 enables the clamping or release of the tailstock assembly 200. Simultaneously, the threaded connection has a self-locking function, maintaining the clamped state after clamping, ensuring the stability of the tailstock assembly 200 during welding.

[0059] Specifically, the clamping component 106 is a lead screw, and a lead screw nut that mates with the lead screw is fixedly mounted on the second support component 104. The lead screw passes through the lead screw nut, and one end of the lead screw is connected to the first rotating component 108. When the operator rotates the lead screw, the lead screw moves along its own axis under the threaded engagement of the lead screw nut, thereby pushing the first rotating component 108 to slide along the first support component 116 to move closer to or away from the drive assembly 110. Conversely, rotating the lead screw in the opposite direction causes it to move in the opposite direction, driving the first rotating component 108 away from the drive assembly 110 to release the rear tailstock of the mine car. Through the lead screw and nut transmission method, the position of the first rotating component 108 can be adjusted. At the same time, the lead screw and nut transmission method has a self-locking property, which can maintain the clamped state after clamping, and can maintain stable clamping of the rear tailstock of the mine car without continuously applying external force, thus ensuring the stability of the rear tailstock assembly 200 during the welding process.

[0060] In some embodiments of the present invention, optionally, such as Figure 1 As shown, the welding workstation 100 also includes a welding robot 118, which is used to weld the circumferential weld 208 of the tailstock assembly 200.

[0061] In this embodiment, the welding workstation 100 is also equipped with a welding robot 118. The welding robot 118 is used to automatically weld the annular weld 208 on the tailstock assembly 200. The welding robot 118 has advantages such as high welding speed, stable welding quality, and continuous operation. By setting up the welding robot 118, the automated welding of the annular weld 208 can be realized, replacing manual welding, thereby further improving welding efficiency, ensuring the consistency of welding quality, and reducing labor costs. Since the tailstock assembly 200 has two annular welds 208, by using robotic welding, both annular welds 208 can be welded, ensuring welding quality while significantly improving production efficiency.

[0062] In some embodiments of the present invention, optionally, such as Figure 1 As shown, the welding workstation 100 also includes a slide rail 128, which is arranged along the axial direction of the first rotating component 108 and located on one side of the clamping assembly 102 and the drive assembly 110. The welding robot 118 is disposed on the slide rail 128 and can slide relative to the slide rail 128.

[0063] In this embodiment, the welding workstation 100 is also provided with a slide rail 128. The slide rail 128 is arranged along the axial direction of the first rotating component 108 and is located on one side of the clamping assembly 102 and the drive assembly 110. The welding robot 118 is disposed on the slide rail 128 and can slide relative to the slide rail 128. Since the tailstock assembly 200 has an annular weld 208, during the rotation of the tailstock assembly 200 around its own axis, the welding robot 118 needs to move along the axial direction of the tailstock assembly 200 to cover the entire weld. By disposing the welding robot 118 on the slide rail 128, the welding robot 118 can slide along the slide rail 128, thereby moving along the axial direction of the tailstock assembly 200, realizing continuous welding at various positions of the annular weld 208. The working range of the welding robot 118 is extended by the slide rail 128, enabling continuous automated welding of the annular weld 208, thereby improving welding efficiency and welding quality.

[0064] Specifically, the slide rail 128 is fixedly installed on the ground. The slide rail 128 serves as the sliding track for the welding robot 118, providing guidance and support for its sliding motion. The welding robot 118 is mounted on the slide rail 128 and can slide back and forth along it. By fixing the slide rail 128 to the ground, it remains stationary during operation, ensuring the stability of the welding robot 118 during sliding and preventing welding deviations caused by wobbling or displacement of the slide rail 128, thereby guaranteeing welding quality.

[0065] In some embodiments of the present invention, optionally, such as Figure 1 As shown, there are two slide rails 128, which are arranged side by side.

[0066] In this embodiment, by setting two parallel slide rails 128, the welding robot 118 slides simultaneously on both slide rails 128. The two slide rails 128 jointly support and guide the welding robot 118, making the force on the welding robot 118 more balanced and the movement more stable during the sliding process, thereby improving the motion accuracy of the welding robot 118 and ensuring the welding quality.

[0067] In some embodiments of the present invention, optionally, such as Figure 1 As shown, the welding workstation 100 also includes a controller 130, which is electrically connected to the welding robot 118 and the drive assembly 110 respectively. The controller 130 is used to adjust the working state of the drive assembly 110, the displacement of the welding robot 118, and the welding position of the welding robot 118.

[0068] In this embodiment, the welding workstation 100 is also equipped with a controller 130. The controller 130 is electrically connected to the welding robot 118 and the drive assembly 110. The controller 130 can send control signals to the drive assembly 110 to control the start / stop, rotation direction, and rotation speed of the drive assembly 110; the controller 130 can also send control signals to the welding robot 118 to control the displacement of the welding robot 118 on the slide rail 128 and the welding position of the welding torch 126. Through the coordinated control of the drive assembly 110 and the welding robot 118 by the controller 130, the coordinated operation of the rotation of the drive assembly 110 and the welding of the welding robot 118 can be achieved, that is, while the tailstock assembly 200 rotates with the drive assembly 110, the welding robot 118 continuously welds the annular weld 208. Through the coordinated control of the drive assembly 110 and the welding robot 118 by the controller 130, automated continuous welding of the annular weld 208 is realized, greatly improving welding efficiency.

[0069] In some embodiments of the present invention, optionally, such as Figure 1As shown, the welding robot 118 includes a third support component 120 and a welding component 122. The third support component 120 is slidably connected to the slide rail 128; the welding component 122 is disposed on the third support component 120 and is rotatable relative to the third support component 120.

[0070] In this embodiment, the welding robot 118 includes a third support component 120 and a welding component 122. The third support component 120 is slidably connected to a slide rail 128, enabling the welding robot 118 to slide on the slide rail 128. The welding component 122 is mounted on the third support component 120 and can rotate relative to the third support component 120. During the welding process, the welding component 122 can slide along the slide rail 128 under the influence of the third support component 120, and simultaneously, the welding component 122 itself can rotate relative to the third support component 120 to adjust its posture, thereby enabling welding of the circumferential weld 208 at different positions and angles. The rotation of the welding component 122 relative to the third support component 120 and the sliding of the third support component 120 along the slide rail 128 enhance the flexibility and adaptability of the welding process.

[0071] In some embodiments of the present invention, optionally, such as Figure 1 As shown, the welding component 122 includes a connecting section 124 and a welding torch 126. There are multiple connecting sections 124, which are connected end to end in sequence, and two adjacent connecting sections 124 are rotatably connected. The welding torch 126 is installed on the connecting section 124 located at the end of the multiple connecting sections 124.

[0072] In this embodiment, the welding component 122 consists of multiple connecting segments 124 and a welding torch 126. The connecting segments 124 are connected end-to-end, with adjacent connecting segments 124 rotatably connected, thus forming an articulated robotic arm structure. The connecting segments 124 can rotate relative to each other, allowing the welding torch 126 to achieve multi-degree-of-freedom movement in space. The welding torch 126 is mounted on the end connecting segment 124 among the multiple connecting segments 124, and can move to any position and angle under the influence of the multiple connecting segments 124. Through the relative rotation between the multiple connecting segments 124, the posture of the welding torch 126 can be flexibly adjusted, enabling multi-angle and multi-position welding of the circumferential weld 208, further improving welding flexibility and welding quality.

[0073] Specifically, since the rear tailstock assembly 200 uses medium-thick plates, a large amount of metal needs to be filled when welding the annular weld 208 of the rear tailstock assembly 200, resulting in a large heat input during welding. This leads to significant residual stress and deformation after welding, affecting structural accuracy and strength, and in severe cases, even causing cracking. Therefore, considering the characteristics of the annular weld of the medium-thick plate of the rear tailstock, a welding robot 118 is set up to employ a multi-layer, multi-pass welding process, stacking weld beads layer by layer. For example, the controller 130 controls the welding robot 118 to stack weld beads layer by layer. After each layer of weld beads is completed, the welding component 122 adjusts the spatial posture of the welding torch 126 to perform the welding of the next layer. The welding parameters of each layer of weld beads change layer by layer as the number of weld beads increases, thereby effectively reducing the welding heat input, reducing welding deformation and residual stress, and significantly improving welding quality. At the same time, by combining with the slide rail 128, the robot's working range can be expanded to achieve continuous automated welding, significantly improving welding quality and production efficiency.

[0074] In some embodiments of the present invention, optionally, such as Figure 1 As shown, the drive assembly 110 includes a second rotating component 112 and a drive component 114. The second rotating component 112 includes the output terminal of the drive assembly 110; the drive component 114 is connected to the second rotating component 112 and is capable of driving the second rotating component 112 to rotate relative to the drive component 114.

[0075] In this embodiment, the drive assembly 110 includes a second rotating component 112 and a drive component 114. The second rotating component 112 includes the output end of the drive assembly 110 for connection to a second side of the tailstock assembly 200. The drive component 114 is connected to the second rotating component 112 and provides driving force for the rotation of the tailstock assembly 200. When the drive component 114 is working, it drives the second rotating component 112 to rotate relative to the drive component 114. The second rotating component 112 transmits power to the tailstock assembly 200 through the output end of the drive assembly 110, thereby driving the tailstock assembly 200 to rotate around its own axis. By driving the second rotating component 112 to rotate through the drive component 114, reliable drive for the rotation of the tailstock assembly 200 is achieved.

[0076] Specifically, the first support component 116 supports the clamping assembly 102 and the first rotating component 108. The tailstock assembly 200 is positioned and clamped by the clamping assembly 102, with its two ends respectively connected to the drive assembly 110 and the first rotating component 108. The controller 130 controls the drive assembly 110 to rotate the tailstock assembly 200, adjusting the annular weld 208 to a horizontal, boat-shaped welding position. Simultaneously, the controller 130 coordinates with the rotation of the welding robot 118 mounted on the slide rail 128 to adjust its movement and the posture of the welding torch 126, working in conjunction with the rotation of the drive assembly 110 to complete the automated robotic welding operation of the tailstock assembly 200. This ensures welding quality and consistency while significantly improving production efficiency. The welding workstation 100 is equipped with a drive assembly 110 and a first rotating component 108 to provide end support for the tailstock assembly 200. The drive assembly 110 drives the tailstock assembly 200 to rotate, transforming the circumferential weld 208 into a horizontal, boat-shaped weld, avoiding unfavorable welding positions such as overhead and vertical welding, and significantly reducing welding defects. The welding workstation 100 is equipped with a welding robot 118, which works in coordination with the drive assembly 110 through program control by the controller 130 to complete automated robotic welding operations, greatly improving welding quality and efficiency.

[0077] Specifically, welding workstation 100 is a semi-automatic tailstock welding workstation.

[0078] Specifically, the process for the rear tailstock assembly 200 involves manually welding two circumferential welds 208 to connect the first tailstock 202 and the second tailstock 204 to the intermediate cylinder 206. Manual welding is prone to defects such as slag inclusions and incomplete penetration, resulting in inconsistent weld quality and low production efficiency. This invention utilizes a semi-automated rear tailstock welding workstation 100 to replace manual welding of the circumferential welds 208, ensuring weld quality while significantly improving production efficiency and allowing for multi-machine operation by a single person.

[0079] Specifically, the rear tail assembly 200 is used in vehicles such as dump trucks, mining trucks, or lorries.
