Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and in particular to an end wall welding and grinding device. Background Technology

[0002] In the field of mechanical manufacturing and processing, welding and grinding processes have always been crucial. End walls, as large components, are typically composed of beams and multiple plates joined together by welding to form a structure with a certain strength and stability. The specific construction of end walls varies depending on different application scenarios and design requirements. For example, in industries such as shipbuilding, automotive, and construction, the shape, size, and material of the plates used in end walls will differ. With the continuous development of industry, the demand for welding and grinding of various large components such as end walls is increasing, which has not only driven the advancement of welding and grinding technologies but also prompted continuous innovation in related equipment.

[0003] In the past, the method used in the welding and grinding of end walls was to first spot weld and fix the beam and the block plate, and then slowly move the end wall from one pre-assembly station to another welding station using a transport device. After the welding of the front side of the end wall was completed, the personnel used large lifting equipment such as cranes to flip the end wall and weld the back side again. After the welding of the front and back sides was completed, it was transported to the grinding station for grinding.

[0004] This method requires significant manpower and time. Traditionally, welding and grinding operations primarily involve welding the weld seams on both sides of the end wall. Workers typically use welding guns and grinding tools, relying on experience and skill to operate the end wall. During the process, workers need to constantly adjust their position and pressure. Due to the limitations of worker skill and physical strength, it's difficult to guarantee the consistency and precision of welding and grinding, resulting in inconsistent product quality. Furthermore, welding on one side of the end wall causes stress changes as the weld seam cools. When the plate is flipped and welded again, it experiences secondary stress changes, which can affect the structural stability of the end wall and increase the risk of deformation.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0018] This application discloses an end-wall welding and grinding device.

[0019] Reference Figure 1 and Figure 2 An end wall welding and grinding device includes a support 1, a transport component 2, a flipping component 3, a welding and grinding component 4, and a moving component 5. After the end wall is assembled and initially fixed, it is placed horizontally on the transport component 2. Then, it is moved to the flipping component 3 by the transport component 2. The flipping component 3 clamps the end wall and flips it to a vertical position. Then, the moving component 5 drives the welding and grinding component 4 to simultaneously weld and grind both sides of the end wall at the welding point. Compared with the welding method on both sides, the simultaneous welding method reduces the number of stress changes in the plate and improves the end wall's load-bearing capacity and impact resistance.

[0020] Reference Figure 1 In this application, the transport component 2 is a roller conveyor belt, and personnel place the initially fixed end wall on the rollers for transport.

[0021] Reference Figure 1 The flipping assembly 3 includes a hoist 31, a clamping member 32, and a flipping cylinder 33. The flipping cylinder 33 is driven to move vertically by the hoist 31. The flipping cylinder 33 drives the clamping member 32 to rotate along the first direction. The clamping member 32 is used to clamp the end wall. There are two flipping assemblies 3, which are located on both sides of the conveying direction of the transport assembly 2. Thus, when the initially fixed end wall is transported to the two clamping members 32 by the transport component 2, after the two clamping members 32 clamp the two sides of the end wall, the hoist 31 drives the end wall to move upward, and then the tilting cylinder 33 drives the clamping members 32 to tilt, thereby driving the end wall to tilt to a vertical state.

[0022] Reference Figure 1 , Figure 2 and Figure 5 In this application, the first direction is horizontally perpendicular to the moving direction of the transport component 2, the second direction is parallel to the moving direction of the transport component 2, and the third direction is vertical. The moving component 5 includes a first moving part 51, a second moving part 52, and two third moving parts 53. The first moving part 51 is fixed on the bracket 1. In this application, the first moving part 51 is a linear motor. The guide rail of the first moving part 51 is arranged above the flipping component 3 along the first direction. The second moving part 52 is mounted on the slide of the first moving part 51, and the first moving part 51 is used to drive the second moving part 52 to move in a first direction; In this application, the third moving part 53 is a linear motor. The slide rail of the third moving part 53 is arranged along a third direction. One end of the slide rail of the third moving part 53 is installed on the second moving part 52. The second moving part 52 is used to drive the two third moving parts 53 to move closer or further apart. A welding grinding assembly 4 is installed on one of the third moving parts 53. The third moving part 53 is used to drive the welding grinding assembly 4 to move along a third direction. The flipping assembly 3 is located at the symmetrical center of the two third moving parts 53. A camera is provided on the third moving part 53. Thus, after the flipping component 3 flips the end wall to a vertical position, the personnel first fix the welding head 41 and the third moving part 53. The first moving part 51 drives the second moving part 52 to move to the end wall, so that the two third moving parts 53 are located on both sides of the end wall. The welding head 41 is moved along the X, Y, and Z axes by the first moving part 51, the second moving part 52, and the third moving part 53. The camera on the third moving part 53 determines that the welding head 41 is aligned with the weld. The second moving part 52 drives the two third moving parts 53 to move closer at the same time, so that the two sides of the weld are welded simultaneously. Compared with the positive and negative welding method, the stress changes twice are reduced, and the end wall's bearing capacity is further improved. After welding is completed, the welding head 41 is replaced with a grinding head 42 to grind the weld.

[0023] Reference Figure 1 and Figure 2To achieve synchronous movement of the two moving parts, the second moving part 52 includes a first guide rail 521, a bidirectional lead screw 522, and two first mounting seats 523. The first guide rail 521 is arranged horizontally and perpendicular to the first direction, and one end of the first guide rail 521 is fixed to the slide of the first moving part 51. The bidirectional lead screw 522 is arranged parallel to the first guide rail 521 and is coaxially rotatably connected to the first guide rail 521. The bidirectional lead screw 522 has two symmetrically distributed threaded segments with opposite threads. The bidirectional lead screw 522 is driven to rotate by a motor. The first mounting seats 523 slide along the length of the first guide rail 521. Each first mounting seat 523 is provided with a nut ring 524, which is coaxially threadedly connected to the bidirectional lead screw 522. Each threaded segment is provided with a first mounting seat 523. A third moving part 53 is mounted on one first mounting seat 523. In this way, the motor drives the bidirectional lead screw 522 to rotate, and the nut ring 524 is threadedly connected to the bidirectional lead screw 522, which drives the first mounting base 523 to move on the first guide rail 521, thereby realizing that the two third moving parts 53 move closer or further apart.

[0024] Reference Figure 1 and Figure 2 During the welding process of the end wall, it is necessary to weld reinforcing ribs on both sides of the end wall. Since the reinforcing ribs are set in different positions, the welding heads 41 on both sides need to be welded along different trajectories. Thus, the first guide rail 521 includes a fixing member 525 and two second guide rails 5211 of equal length. The two second guide rails 5211 are connected by the fixing member 525 to form the first guide rail 521. There are two first moving members 51. Each first moving member 51 drives one second guide rail 5211 to move along the first direction. The bidirectional lead screw 522 includes two lead screw segments 5221 divided symmetrically along two threaded sections. Each lead screw segment 5221 has the same threaded section. The two lead screw segments 5221 are formed by a fixing member 525 to form the bidirectional lead screw 522. A first mounting base 523 moves on a second guide rail 5211. A nut ring 524 is threadedly connected to one lead screw segment 5221. Therefore, when different welding trajectories are required, the two second guide rails 5211 and the lead screw segment 5221 are separated by the fixing component 525, thereby allowing the two third moving components 53 to move independently to weld different welding trajectories on both sides of the end wall.

[0025] Reference Figure 3 In order to splice and fix the two second guide rails 5211 and the two threaded sections, the fixing component 525 includes an electromagnet 5251 and a columnar magnetic column 5252. The two guide rails 5211 are close to each other at one end and have a first insertion slot along the length of the first guide rail 521. One of the second guide rails 5211 has an electromagnet 5251 at the bottom of the first insertion slot, and the other second guide rail 5211 has a magnetic column 5252 in the first insertion slot. The magnetic column 5252 is elastically slidably connected in the first insertion slot. Normally, the magnetic column 5252 is located in the first insertion slot away from the electromagnet 5251. Two lead screw segments 5221 are provided with a second insertion slot with a polygonal cross-section at one end close to each other along the length of the first guide rail 521. One lead screw segment 5221 is provided with an electromagnet 5251 at the bottom of the second insertion slot, and the other lead screw segment 5221 is provided with a magnetic column 5252 in the second insertion slot. The magnetic column 5252 is elastically slidably connected in the second insertion slot. Normally, the magnetic column 5252 is located in the second insertion slot away from the electromagnet 5251. In this application, the insertion end of the magnetic post 5252 is chamfered to facilitate the insertion of the magnetic post 5252; Therefore, when splicing is required, the electromagnet 5251 is energized to generate magnetism, which attracts the magnetic column 5252 into the first insertion slot and the second insertion slot, thus completing the splicing of the two second guide rails 5211 and the two threaded sections. In this application, after the two lead screw sections 5221 are spliced, a motor drives one lead screw section 5221 to rotate, which in turn drives the other lead screw section 5221 to rotate, thus avoiding damage to the bidirectional lead screw 522 due to the speed difference between the two motors.

[0026] Reference Figure 2 and Figure 4 In order to ensure that the two third moving parts 53 are in symmetrical positions after splicing, an end wall welding and grinding device also includes a calibration component 6. The calibration component 6 includes a guide rod 61, which is set parallel to the second guide rail 5211, and one guide rod 61 is installed on one second guide rail 5211. The nut ring 524 is coaxially rotatably connected to the first mounting base 523. A limit rod 62 is elastically slidably connected to the nut ring 524 along a direction parallel to its meridian. The end of the limit rod 62 away from the nut ring 524 is provided with a wedge-shaped surface 621. The guide rod 61 is provided with a clearance opening 622 on the side near the bidirectional lead screw 522. When the two first mounting seats 523 move away from each other to the clearance opening 622, the wedge-shaped surface 621 of the limiting rod 62 abuts against the side wall of the clearance opening 622, causing the limiting rod 62 to move toward the nut ring 524. Therefore, when the two threaded sections are connected to each other, and the position of the two third moving parts 53 needs to be calibrated, the motor drives the bidirectional screw 522 to rotate, causing the two first mounting seats 523 to move away from each other until they reach the clearance opening 622. At this time, since the side wall of the clearance opening 622 abuts against the wedge-shaped surface 621 of the limiting rod 62, the limiting rod 62 moves towards the bidirectional screw 522. Since there is no limitation from the limiting rod 62, the nut ring 524 rotates with the bidirectional screw 522 on the first mounting seat 523 and cannot move. When the nut rings 524 on both first mounting seats 523 have rotated, the bidirectional screw 522 is rotated in the opposite direction. The side of the limiting rod 62 away from the wedge-shaped surface 621 abuts against the side wall of the clearance opening 622, restricting the rotation of the nut ring 524. This causes the nut ring 524 to move towards the center of the bidirectional screw 522, thus calibrating the position of the two third moving parts 53.

[0027] In this application, in order to further optimize the calibration effect, when the limit rod 62 moves to the clearance opening 622, the first mounting base 523 moves to the end of the first guide rail 521 and stops moving.

[0028] Reference Figure 2 , Figure 5 and Figure 6 During the welding or grinding process, in order to achieve better welding and grinding, the welding head 41 and the grinding head 42 need to be in contact with the weld at a certain angle. Therefore, an end wall welding and grinding device also includes an angle adjustment component 7. The angle adjustment component 7 includes a second mounting base 71, a first driving component 72, a second driving component 73, a universal ball 73, a first connecting rod 74 and a second connecting rod 75. A second mounting base 71 is mounted on a third moving component 53. In this application, the first driving component 72 is a motor, and the first driving component 72 is mounted on the second mounting base 71. In this application, the second driving component 73 is a cylinder, and the second driving component 73 is mounted on the first driving component 72. The first driving component 72 is used to drive the second driving component 73 to rotate, and the rotation axis is parallel to the second direction. The omnidirectional ball 73 is located on the side of the first drive member 72 away from the second mounting base 71 and is ball-hinged with the second mounting base 71. The omnidirectional ball 73 is provided with a first mounting post 76, which is connected to the welding head 41 and the grinding head 42 through the fixing member 525. The first link 74 is located between the universal ball 73 and the second drive member 73, and one end of the first link 74 is fixedly connected to the universal ball 73. The second link 75 is rotatably connected at one end to the first link 74 and at the other end to the second drive member 73. The second drive member 73 is used to drive the end of the second link 75 away from the first link 74 to move toward the universal ball 73. Thus, the second drive member 73 drives the second link 75 to move, and the second link 75 pulls the first link 74 to swing, so that the universal ball 73 drives the first mounting post 76 to swing in a plane. The first drive member 72 drives the universal ball 73 to rotate, thereby changing the first mounting post 76 from two-dimensional swing to three-dimensional swing, which facilitates the alignment of the welding head 41 and the grinding head 42.

[0029] Reference Figure 2 and Figure 5 To facilitate the automatic replacement of the welding head 41 and the grinding head 42, and to allow for the replacement of welding heads 41 and grinding heads 42 of different sizes, the welding and grinding assembly 4 includes a mounting disc 43. The mounting disc 43 is coaxially rotatably connected to the second mounting base 71. In this application, the mounting disc 43 is positioned above the universal ball 73, and the rotation axis of the mounting disc 43 is vertically oriented. Multiple mounting grooves are formed on the peripheral wall of the mounting disc 43 along its meridian direction, with one of the mounting grooves located directly above the universal ball 73. Each of the head 41 and the grinding head 42 is provided with a second mounting post 44. The second mounting post 44 is installed vertically in the mounting groove. The second mounting post 44 is connected to the first mounting post 76 by a fastener 525. The end of the first mounting post 76 is slotted to install an electromagnet 5251. The end of the second mounting post 44 is slotted to elastically install a magnetic post 5252. In this application, in order to facilitate the installation of the second mounting post 44 in the mounting groove, the peripheral wall of the second mounting post 44 is provided with a magnetic layer, and the groove wall of the mounting groove is also provided with a magnetic layer. In this way, after the welding head 41 and grinding head 42 that need to be replaced are moved above the universal ball 73, the first mounting post 76 swings to a vertically upward state. At this time, the first mounting post 76 and the second mounting post 44 are aligned. Then, through the cooperation of the electromagnet 5251 and the magnetic post 5252, the first mounting post 76 and the second mounting post 44 are connected, thereby completing the automatic replacement of welding heads 41 and grinding heads 42 of different sizes.

[0030] Reference Figure 6 In order to improve the grinding quality of the grinding head 42, a third driving component 77 is provided inside the universal ball 73. The third driving component 77 is used to drive the first mounting column 76 to rotate coaxially and be connected to the universal ball 73. In this application, the third driving component 77 is a motor, and the grinding head 42 is a spherical grinding head 42. After the first mounting post 76 is connected to the second mounting post 44 of the grinding head 42, the first mounting post 76 is rotated by the third driving component 77, which in turn drives the second mounting post 44 to rotate, and then drives the grinding head 42 to rotate.

[0031] Reference Figure 2 and Figure 5To prevent the end wall weld from deviating from the center of the bidirectional screw 522 during the end wall flipping process, thus causing the two welding heads 41 to be at different distances from the center point and affecting the welding quality, a measuring rod 78 is slidably connected to the second mounting base 71. The measuring rod 78 slides along the second direction, and a rangefinder 79 is provided on the second mounting base 71 to measure the movement of the measuring rod 78. In this application, two measuring rods 78 are provided on one second mounting base 71, and the measuring rods 78 are moved by an electric push rod. Thus, before the two lead screw segments 5221 are spliced, the distances between the two second mounting seats 71 and the welded joints of the end wall are measured by moving the distance measuring rod 78. The processor calculates the distance difference measured by the two distance measuring instruments 79. Then, the processor controls the motor to start calibration through the controller. The third moving part 53 on the side with the larger distance first moves the end of the second guide rail 5211 of the first mounting seat 523 through the calibration component 6. Then, the lead screw segment 5221 is flipped so that it moves toward the center of the bidirectional lead screw 522 to make up for the distance difference. Then, the two lead screw segments 5221 are spliced ​​together. This makes up for the difference between the end wall and the center of the bidirectional lead screw 522, so that the distance between the two welded joints 41 and the welded joints of the end wall is consistent.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
