Description

Technical Field

[0001] This invention relates to the field of engineering machinery, specifically to a track beam main body splicing device and method. Background Technology

[0002] The main structure of the traveling device of a crawler crane is the crawler beam, which has a complex structure and a complex manufacturing process. The manufacturing process of the crawler beam includes multiple welding steps. The first splicing of the crawler beam is spot welding: the base plate is aligned by marking lines on a platform, and then the wheel spacer plate, inner stiffening plate, central web plate, main lug plate assembly, inner rear web plate, front inner web plate, front outer web plate, front partition plate, inner vertical plate, and top cover plate are manually marked in sequence.

[0003] The inventors discovered that the existing technology has at least the following problems: 1. Low splicing accuracy, which cannot meet the requirements of robotic automated welding; 2.

[0004] This invention proposes a device and method for splicing track beams to improve the efficiency of welding track beam splices.

[0005] This invention provides a track beam main body splicing device, comprising:

[0006] A tooling platform is configured to provide support, the tooling platform including a first direction and a second direction, the first direction and the second direction being perpendicular to each other;

[0011] A first mounting base is slidably connected to the top of the tooling platform; and

[0012] The first positioning plate is fixed to the first mounting base, and the length direction of the first positioning plate is parallel to the first direction of the tooling platform.

[0013] In some embodiments, the spacing between the two first positioning components arranged in pairs in a second direction of the tooling platform is adjustable.

[0017] The positioning plate is installed in the middle or at the top of the side of the second mounting base.

[0018] In some embodiments, the second mounting base includes a plurality of stacked seats that are detachably connected to each other to adjust the height of the second mounting base.

[0019] In some embodiments, a plurality of second mounting seats are arranged along a second direction of the tooling platform, and the second mounting seats are spaced apart.

[0020] In some embodiments, the third positioning component includes:

[0021] A guide rail is detachably mounted to the tooling platform; the length direction of the guide rail is along a first direction of the tooling platform; two of the guide rails are arranged at each end of the tooling platform.

[0022] A sliding seat is slidably mounted on the guide rail, and one sliding seat is mounted on each guide rail;

[0023] A top-mounted retaining portion is vertically and flexibly mounted on the sliding seat; each sliding seat is equipped with one of the retaining portions; and

[0024] A first side clamping portion is vertically mounted on the sliding seat. The first side clamping portion is configured to cooperate with the first side clamping portion of another third positioning assembly to clamp the two opposite side plates of the track beam.

[0025] In some embodiments, the third positioning component further includes:

[0026] The second side clamping part is arranged side by side with the first side clamping part. The first side clamping part is fixedly connected to the top surface clamping part and is located below the top surface clamping part. The second side clamping part is movably mounted on the sliding seat.

[0027] In some embodiments, the third positioning component further includes:

[0028] Multiple third-side retaining parts are arranged between the two sliding seats, and each of the third-side retaining parts can be slidably mounted on the tooling platform along the first direction.

[0029] In some embodiments, the track beam body splicing device further includes:

[0030] A support platform is rotatably mounted on the outer end of the tooling platform; the support platform includes a third direction; the support platform can be rotated relative to the tooling platform to switch between the following positions: a position where the third direction is parallel to the first direction, and a position where the third direction is parallel to the second direction;

[0031] A third mounting base is movably mounted on the tray along the third direction; and

[0032] The motor positioning seat is rotatably mounted on the third mounting seat.

[0033] In some embodiments, the motor positioning seat includes:

[0034] The fourth mounting base is rotatably mounted on the third mounting base;

[0035] A centering chuck is vertically mounted on the fourth mounting base. The centering chuck includes a positioning shaft, the length direction of which is parallel to the third direction.

[0037] In some embodiments, the third positioning component is located at the end of the tooling platform.

[0038] This invention also provides a method for assembling the main body of a track beam, which is implemented using the track beam main body assembly device provided by any of the technical solutions of this invention, and includes the following steps:

[0039] Based on the dimensions of the track beam to be spot-welded, determine the position of each of the first positioning components, such that the two first positioning components arranged in pairs are engaged with the outer side of the bottom plate of the track beam.

[0040] Move the second positioning component to position each partition of the track beam;

[0041] The positioned partition plate is spot welded to the positioned base plate;

[0042] The height of the top clamping part and the position of the side clamping part of the third positioning component are determined to achieve the positioning of each side plate and cover plate of the track beam.

[0043] The base plate, the partition plate, the side plate, and the cover plate are spot welded together.

[0044] In some embodiments, the method for assembling the main body of the track beam further includes the following steps:

[0045] Rotate the support platform of the main track beam splicing device to a position where the third direction is perpendicular to the second direction;

[0046] Install the motor mounting bracket onto the motor positioning bracket of the track beam main body splicing device;

[0047] Rotate the support platform to a position where the third direction is parallel to the first direction;

[0048] The motor mounting bracket is spot welded to the track beam.

[0049] The track beam assembly device provided by the above technical solution uses a first positioning component to position the bottom plate of the track beam. The position of the first positioning component remains unchanged after installation on the tooling platform. The bottom plate of the track beam is directly engaged with the outside of the first positioning component. A second positioning component is used to position the partitions of the track beam. Multiple partitions are arranged in parallel along the length of the track beam. However, it is not necessary to set a second positioning component for each partition; the same positioning component can be used to position each partition one by one: starting from the end of the tooling platform in the second direction (specifically the length direction), the partition is first positioned against the second positioning component, and then spot-welded to the already positioned bottom plate, thus achieving the positioning of the partition. Then, the second positioning component is slid along the length of the tooling platform to the position where the second partition is to be installed, and then the second partition is positioned using the second positioning component and then spot-welded in place. The above steps are repeated until the positioning of all partitions is completed. Both the side plates and the cover plates are positioned using a third positioning assembly. This assembly is located at both ends of the tooling platform along its length, directly positioning the cover plates on the top, the end faces of the side plates, and / or near the end faces. This reduces the number of positioning points and ensures reliable positioning. This technical solution allows for accurate positioning of each plate of the track beam to be spot-welded, enabling simultaneous assembly and spot welding, resulting in efficient and convenient operation.

[0050] The above technical solution can achieve the positioning of the cover plate, bottom plate, side plate, and partition plate of the track beam, with high assembly efficiency. The entire assembly process is basically achieved by positioning components, resulting in high efficiency. The positioning of each part of the track beam does not require repeated marking; the automatic control system can directly achieve precise positioning of each positioning component, resulting in a low degree of automation. The positioning directions of each positioning component are different, enabling precise positioning of the track beam in various directions and convenient adjustment. Attached Figure Description

[0076] The following is combined Figures 1 to 13d The technical solution provided by this invention will be described in more detail below.

[0077] Explanation of the nouns and terms used in this article.

[0078] Track beam, the main structure of the crawler crane's traveling mechanism.

[0079] A servo system is an automatic control system that enables the output of an object, such as its position, orientation, and state, to change in response to any change in the input.

[0080] The assembly process involves combining multiple parts into a single unit, with the joints secured by weld points or small welds.

[0081] Track beam 8 is the main structure of the crawler crane's traveling mechanism. See also... Figures 2 to 5 The track beam 8 is a beam-shaped structure, comprising a cover plate 84, a bottom plate 81 opposite to the cover plate 84, a side plate 83 disposed between the cover plate 84 and the bottom plate 81, and partitions 82 fixedly connected to the cover plate 84, the bottom plate 81, and the side plate 83. The bottom plate 81, the cover plate 84, and the side plate 83 are all elongated structures. The length directions of the cover plate 84 and the bottom plate 81 are approximately parallel. The side plate 83 is perpendicular to the cover plate 84 and the bottom plate 81, and its length direction is approximately parallel to both the cover plate 84 and the bottom plate 81. Multiple partitions 82 are distributed along the length direction of the cover plate 84.

[0082] The track beam assembly device provided in this embodiment of the invention quickly and accurately positions and assembles the cover plate 84, side plate 83, and partition plate 82. Furthermore, during the assembly process, each assembled piece is spot-welded, thus improving the efficiency and accuracy of track beam assembly. In this invention, all movable positioning components can be clamped and positioned using a hydraulic / electric coordinated manual clamping method.

[0083] In this paper, for ease of description, the first direction of the tooling platform 1 is defined as the width direction of the tooling platform 1, and the second direction of the tooling platform 1 is defined as the length direction.

[0084] See Figures 1 to 3 This invention provides a track beam main body splicing device, including a tooling platform 1, a first positioning component 2, a second positioning component 3, and a third positioning component 4. The tooling platform 1 is configured to provide support and includes a first direction and a second direction, which are perpendicular to each other. The first positioning components 2 are arranged in pairs; the first positioning components 2 are movably disposed on the tooling platform 1 along the first direction, such that the spacing between the pair of first positioning components 2 along the first direction is adjustable; the first positioning components 2 are configured to position the bottom plate 81 of the track beam 8. The second positioning component 3 is slidably mounted on the tooling platform 1 along the second direction, and is configured to position the partition plate 82 of the track beam 8. The third positioning component 4 is located at both ends of the tooling platform 1; the third positioning component 4 is configured to be movable along both the first and second directions, and is configured to position the cover plate 84 and side plate 83 of the track beam 8.

[0085] Tooling platform 1 is a large platform that can accommodate track beam structural components with a maximum weight of 800t. Tooling platform 1 is equipped with a manual assembly device to enable manual assembly, so that the track beam main body assembly device has multiple functions of automatic assembly and manual assembly.

[0086] See Figures 1 to 3 Along the length of the tooling platform 1, multiple pairs of first positioning components 2 are arranged. At least one first positioning component 2 is provided at each edge of the tooling platform 1 in the width direction (first direction), with two first positioning components 2 located at two edges in the width direction forming a pair. The two first positioning components 2 cooperate to clamp the base plate 81 to be assembled. The paired first positioning components 2 are symmetrically arranged with respect to the centerline of the tooling platform 1. In some embodiments, the spacing between the paired first positioning components 2 in the second direction of the tooling platform 1 is adjustable to meet the positioning requirements of base plates 81 of different widths.

[0087] Each first positioning component 2 slides relative to the tooling platform 1 through a servo system or an electronic control system to meet the support requirements of base plates 81 of different widths.

[0088] Specifically, see Figure 7 Each first positioning component 2 includes a first mounting base 21 and a first positioning plate 22. The first mounting base 21 is slidably connected to the top of the tooling platform 1. The first mounting base 21 includes a support base 211 and a first drive unit 212 for driving the support base 211 to move, such as a motor. The motor drives the seat body 311 to move along the width direction of the tooling platform 1 to clamp the bottom plate 81 of track beams 8 of different widths. The seat body 311 is approximately U-shaped, and the sides of the U-shape clamp the outer side of the bottom plate 81 of the track beam 8. The first positioning plate 22 is fixed to the first mounting base 21, and the length direction of the first positioning plate 22 is parallel to the first direction of the tooling platform 1. The bottom of the first positioning plate 22 is slidably or fixedly connected to the tooling platform 1, and the top edge of the first positioning plate 22 is bent to form a support surface for supporting the bottom plate 81 of the track beam 8. The bottom of the bottom plate 81 of the track beam 8 is supported by the first positioning plate 22. The first mounting seats 21 of the two paired first positioning components 2 clamp together the side of the bottom plate 81 of the track beam 8. This achieves accurate positioning of the bottom plate 81 of the track beam 8.

[0089] The above technical solution is a new servo control splicing technology. The tooling platform 1 has a first positioning pin 12 at one end and second positioning pins 13 on both sides. When lifting parts, the end of the base plate 81 is placed against the first positioning pin 12. The position of the first positioning pin 12 is changed according to the different end positions of the base plate 81; the position of the second positioning pin 13 is changed according to the different inner widths of the base plate 81. This enables rapid production of the same type of track beam 8 and also allows for easy replacement of the track beam 8 type.

[0090] See also Figure 7 Because the bottom plate 81 of the track beam 8 is relatively long, to prevent bending or other phenomena in the middle position of the bottom plate 81 under load, the main body splicing device of the track beam also includes multiple support components 23. Multiple support components 23 are arranged at intervals along the length of the tooling platform 1. Each support component 23 includes a support platform 231 that can slide along the width direction of the tooling platform 1 and a support plate 232 installed on top of the support platform 231. The support plate 232 can be fixedly installed on the support platform 231 or can be installed on the support platform 231 in a height-adjustable manner. By adjusting the height of the support plate, the support requirements of bottom plates 81 at different heights can be accommodated.

[0091] See Figure 2 and Figure 8 The track beam 8 includes multiple partitions 82, which are distributed along the length of the track beam 8. When spot welding the partitions 82, one second positioning component 3 can be used to position each partition 82 individually, or two second positioning components 3 can be used to position two partitions 82 simultaneously, starting from both ends of the track beam 8 along its length. After each partition 82 is positioned, it is spot welded in place. After spot welding, the partition 82 can be fixed in its pre-set position without the second positioning component 3.

[0092] See Figure 8 In some embodiments, the second positioning component 3 includes a second mounting base 31 and a positioning plate 32. The second mounting base 31 is linearly slidably mounted on the tooling platform 1; the second mounting base 31 protrudes from the surface of the tooling platform 1. The positioning plate 32 is magnetic, which facilitates the positioning of the partition 82. The positioning plate 32 is mounted on the middle or top of the side of the second mounting base 31. The second positioning component 3 also includes a first positioning element (not shown in the figure), and the tooling platform 1 includes a second positioning element (not shown in the figure). The first positioning element and the second positioning element are, for example, both of them are positioning pins, and the two cooperate to realize the adjustment of the spacing between different partitions 82.

[0093] A sliding rail 11 is installed at the centerline of the tooling platform 1, and the length direction of the sliding rail 11 is the same as the length direction of the tooling platform 1. A second mounting base 31 is installed on the sliding rail 11 and can slide along the sliding rail 11. By sliding the second mounting base 31, the different partitions 82 can be positioned. A positioning plate 32 is detachably installed on the side of the second mounting base 31, and the positioning plate 32 is arranged parallel to the partitions 82.

[0094] In some embodiments, a plurality of second mounting seats 31 are arranged along the second direction of the tooling platform 1, and the second mounting seats 31 are spaced apart. Each second mounting seat 31 is mounted on the same sliding rail. This reduces the number of sliding rails and improves the positioning efficiency of the partition 82, thereby improving the spot welding efficiency of the track beam 8.

[0095] The track beams 8 have different structural dimensions, and the heights of the partitions 82 on the track beams 8 also vary. To achieve positioning of partitions 82 at different heights, in some embodiments, the second mounting base 31 includes multiple stacked seats 311, which are detachably connected to each other to adjust the height of the second mounting base 31. Each seat 311 is equipped with a positioning plate 32. By setting an appropriate number of seats 311, positioning of partitions 82 at different heights can be achieved.

[0096] The second positioning component 3 adopts servo control technology. After a single part is assembled, the second positioning component 3 can automatically move to the corresponding position to facilitate the assembly of the next part.

[0097] See Figure 9 In some embodiments, the third positioning component 4 includes a guide rail 41, a sliding seat 42, a top surface retaining portion 43, and a first side clamping portion 44. The guide rail 41 is detachably mounted to the tooling platform 1; the length direction of the guide rail 41 is along a first direction of the tooling platform 1; two guide rails 41 are arranged at each end of the tooling platform 1. The sliding seat 42 is slidably mounted to the guide rail 41 along the guide rail 41, and one sliding seat 42 is mounted on each guide rail 41. The top surface retaining portion 43 is vertically mounted to the sliding seat 42; one retaining portion is mounted on each sliding seat 42. The first side clamping portion 44 is vertically mounted to the sliding seat 42 and is configured to cooperate with the first side clamping portion 44 of another third positioning component 4 to clamp the two opposing side plates 83 of the track beam 8.

[0098] The guide rail 41 is a cylindrical rod, and a through hole 421 is provided in the middle of the bottom of the sliding seat 42, through which the guide rail 41 passes. The position of the sliding seat 42 is precisely controlled by components such as a servo motor.

[0099] See Figure 1As shown, the height of the sliding seat 42 is higher than the height of the track beam 8 to be spot welded. The top surface clamping part 43 presses against the cover plate 84 of the track frame from the top. The two first side clamping parts 44 located at the two edges of the width of the tooling platform 1 cooperate to clamp the ends of the two opposite side plates 83 of the track beam 8. A total of four sliding seats 42 are arranged on the tooling platform 1, which cooperate in pairs to clamp the ends of the two side plates 83 of the track beam 8.

[0100] See Figure 9 and Figure 10 In addition to its ability to slide along the first direction, the sliding seat 42 also serves as the mounting base for the first side clamping part 44 and the second side clamping part 45, which will be described later. The sliding seat 42 has a first sliding groove 422, which is parallel to the height direction of the sliding seat 42. The first side clamping part 44 is vertically and flexibly mounted in the first sliding groove 422. By adjusting the height of the first side clamping part 44, the positioning requirements of the side plates 83 of the track beam 8 with different height dimensions can be met.

[0101] The top-mounted clamping part 43 and the first side clamping part 44 are fixed together and rise and fall synchronously. Specifically, the rising and falling can be achieved through a screw-driven lifting mechanism to accommodate different heights of different models of cover plates 84. The top-mounted clamping part 43 includes a cantilever 431 and a top fixing plate 432 fixed to the free end of the cantilever 431. The top fixing plate 432 is used to press down the cover plate 84 of the track beam 8. The top-mounted clamping part 43 also includes a first positioning pin (not shown in the figure), and the sliding seat 42 includes a second positioning pin (not shown in the figure). The first positioning pin and the second positioning pin cooperate to achieve compatibility of cover plates 84 of different lengths. The side plate 83 is positioned along its length by an adjacent partition plate 82. The top fixing plate 432 can be made of magnetic material. The screw-driven lifting mechanism can adjust the height of the electromagnet.

[0102] See Figure 9 and Figure 10 The sliding seat 42 also has a second sliding groove 423, which is arranged in parallel with the first sliding groove 422. The third positioning component 4 also includes a second side clamping part 45, which is arranged side by side with the first side clamping part 44. The first side clamping part 44 is fixedly connected to the top surface clamping part 43 and is located below the top surface clamping part 43. The second side clamping part 45 is vertically and flexibly mounted on the sliding seat 42.

[0103] See Figure 11The third positioning component 4 also includes multiple third side retaining parts 46 arranged between two sliding seats 42. Each third side retaining part 46 can be slidably mounted on the tooling platform 1 along the first direction. Specifically, the third side retaining part 46 adopts an L-shaped plate. One plate of the L-shaped plate can be slidably mounted on the tooling platform 1, and the other plate of the L-shaped plate is used as a positioning plate 32 to position the middle of the side plate 83 of the track beam 8. Multiple third side retaining parts 46 can increase the positioning support position of the side plate 83, so that the side plate 83 of the track beam 8 can be positioned more accurately.

[0104] Back Figure 1 In some embodiments, the track beam main assembly device also includes a support platform 5, a third mounting base 6, and a motor positioning base 7.

[0105] The support platform 5 is installed on the outer end of the tooling platform 1; the support platform 5 includes a third direction; the support platform 5 can rotate relative to the tooling platform 1 to switch between the following positions: a position where the third direction is parallel to the first direction, and a position where the third direction is parallel to the second direction. When it is necessary to install the motor, first rotate the support platform 5 to a position where it will not interfere with the tooling platform 1; then place the motor; after the motor is in place, rotate the support platform 5 and the motor together to a position where the third direction of the support platform 5 is parallel to the first direction of the tooling platform 1, i.e. Figure 1 The indicated location.

[0106] See Figure 1 The third mounting base 6 is movably mounted on the platform 5 along a third direction. The motor positioning base 7 is rotatably mounted on the third mounting base 6. The position of the motor positioning base 7 on the platform 5 is adjusted via the third mounting base 6. The motor positioning base 7 is used to mount the motor mounting base 9, which is used to mount the motor. The position of the motor mounting base 9 matches the position of the track beam 8.

[0107] See also Figure 1 In some embodiments, the motor positioning base 7 includes a fourth mounting base 71 and a centering chuck 72. The fourth mounting base 71 is rotatably mounted on the third mounting base 6, with a rotation angle of, for example, 180°. The centering chuck 72 is vertically mounted on the fourth mounting base 71, specifically through a lead screw connection. The centering chuck 72 includes a positioning shaft, the length of which is parallel to a third direction. The centering chuck 72 is adjustable in three directions: rotation, lifting, and a third direction.

[0108] In some embodiments, the track beam main assembly device further includes a hydraulic control system, which is drivenly connected to the first positioning component 2, the second positioning component 3, and the third positioning component 4 to achieve precise control of the position of each positioning component.

[0109] Compared to the manual marking and splicing method used in existing technologies, the servo motor-controlled track beam splicing technology allows for the same type of track beam 8 structure to be programmed and stored only once. During subsequent production, the previously saved program can be directly recalled for one-click adjustment, significantly improving splicing efficiency. The entire process is highly efficient and precise. After the individual parts of the track beam 8 are spliced, the servo-controlled fixture can automatically release the clamping force and move to the corresponding position via program control, facilitating loading and unloading.

[0110] See Figure 12 This invention provides a method for assembling the main body of a track beam, implemented using the track beam main body assembly device provided by any of the technical solutions of this invention, including the following steps:

[0111] Step S100: Determine the position of each first positioning component 2 according to the size of the track beam 8 to be spot welded, so that the two first positioning components 2 arranged in pairs are locked onto the outer side of the bottom plate 81 of the track beam 8.

[0112] Step S200: Move the second positioning component 3 to position each partition 82 of the track beam 8.

[0113] Step S300: Spot weld the positioned partition plate 82 to the positioned base plate 81.

[0114] Step S400: Determine the height of the top clamping part 43 and the position of the side clamping part of the third positioning component 4 to achieve positioning of each side plate 83 and cover plate 84 of the track beam 8.

[0115] Step S500: Spot weld the base plate 81, partition plate 82, side plate 83, and cover plate 84 to fix them.

[0116] In the above assembly process, assembly and spot welding are carried out consecutively; one part is assembled and then spot welded. The assembly efficiency is high.

[0117] In some embodiments, the method for assembling the main body of the track beam further includes the following steps:

[0118] Step S600: Rotate the support platform 5 of the main track beam splicing device to a position where the third direction is perpendicular to the second direction.

[0119] Step S700: Install the motor mounting base 9 onto the motor positioning base 7 of the track beam main body splicing device.

[0120] Step S800: Rotate the support 5 to a position where the third direction is parallel to the first direction.

[0121] Step S900: Spot weld the motor mounting base 9 to the track beam 8.

[0122] The above technical solution enables the rapid assembly of the track beam 8 and the motor mounting base 9.
