Description

Technical Field

[0001] This utility model relates to the field of welding component technology, and in particular to a welding component for an integral side beam of an excavator. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, the technology related to welding components is also constantly improving. The side beam is a core component of an excavator. The left and right side beams consist of three parts: the tensioner part, the intermediate body part, and the drive unit. The left and right side beams are symmetrical in structure. Before the overall assembly, the tensioner part and the drive unit are assembled separately. Then, the intermediate body part is assembled on the overall assembly jig and positioned and welded into a whole. At the same time, the drive unit is positioned and welded to the intermediate body part, and the intermediate body part is positioned and welded to the tensioner part, so that the three parts become a whole. Then, the jig is removed and the machine is hoisted onto the positioner for overall welding.

[0003] Currently, when welding the integral side beam of an excavator, it is not possible to quickly position it. It is necessary to perform positioning treatment first before welding can be carried out. The positioning treatment is time-consuming and does not improve welding efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: Currently, when welding the integral side beam of an excavator, it is impossible to quickly position it. It is necessary to perform positioning treatment first before welding can be carried out. The positioning treatment is time-consuming and not conducive to improving welding efficiency. Therefore, this utility model proposes an integral side beam welding component for excavators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integral side beam welding assembly for an excavator includes a side beam body, a fixing sleeve installed on the outer side of the side beam body, a locking assembly provided on the fixing sleeve, two openings on the fixing sleeve, a slide bar slidably connected in each opening, an adjusting plate fixedly connected to the slide bar, and two limiting blocks fixedly connected to the adjusting plate.

[0007] The back of the fixing sleeve has an installation cavity. A rotating shaft is connected to the installation cavity by a torsion spring. Two rotating rods are fixedly connected to the rotating shaft. Two horizontal bars are slidably arranged in the installation cavity. The two horizontal bars are connected to the two fixed rods and the two sliding bars respectively. A slider is slidably connected to each horizontal bar. Each rotating rod is hinged to the corresponding slider. A rotating block with a cross-shaped cross section is rotatably connected to the fixing sleeve. The rotating block is connected to the rotating shaft by a first pull rope.

[0008] Preferably, the locking assembly includes an L-shaped plate fixedly mounted on the upper surface of the fixed sleeve, a threaded rod threadedly connected to the L-shaped plate, and a plurality of threaded holes for connecting the threaded rod on the rotating block.

[0009] Preferably, the back of the side beam body is provided with a slot with an L-shaped cross-section, a positioning block is fixedly connected to one side of the fixing sleeve, a vertical cavity is provided inside the fixing sleeve, and a limiting strip with an L-shaped cross-section is slidably connected inside the vertical cavity, and the limiting strip and the positioning block are slidably connected.

[0010] Preferably, the upper surface of the fixing sleeve is provided with a convex groove, and an I-shaped block is slidably installed in the convex groove. The I-shaped block is connected to the limiting strip by a second pull rope, and a connecting hole is provided on the I-shaped block.

[0011] Preferably, a return spring is fixedly connected to one inner wall of the convex groove, and the return spring is fixedly connected to the I-shaped block.

[0012] Preferably, two positioning holes are provided on both the upper and lower surfaces of the side beam body, and multiple positioning strips arranged symmetrically are fixedly connected to the fixing sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] After placing the external connector inside the two openings, the rotating block is rotated to wind up the first pull rope. Under the transmission action of the inelastic first pull rope, the rotating shaft will rotate in the mounting cavity. During the rotation of the two rotating rods, the two sliders will slide respectively. The two horizontal bars slide vertically in the mounting cavity at the same time, and the distance between the two horizontal bars will decrease. Under the transmission action of the fixed rod, the distance between the two adjusting plates will also decrease. After each limit block moves, it will engage with the corresponding slot on the external connector. Finally, the threaded rod is rotated again so that it passes through the round hole and is threadedly connected to the corresponding threaded hole, which can achieve rapid positioning of the side beam body. Welding can then be performed. The positioning process is relatively quick, which helps to improve the welding efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0022] Reference Figures 1-4 A welded integral side beam assembly for an excavator includes a side beam body 1, a fixing sleeve 2 installed on the outer side of the side beam body 1, a locking assembly on the fixing sleeve 2, two openings 3 on the fixing sleeve 2, a slide bar 14 slidably connected in each opening 3, an adjusting plate 4 fixedly connected to the slide bar 14, two limiting blocks 5 fixedly connected to the adjusting plate 4, an installation cavity 10 on the back of the fixing sleeve 2, a rotating shaft 9 connected in the installation cavity 10 by a torsion spring, two rotating rods 12 fixedly connected to the rotating shaft 9, two horizontal bars 13 slidably arranged in the installation cavity 10, the two horizontal bars 13 are respectively connected to the two fixed rods 22 and the two slide bars 14, a slider 11 slidably connected to each horizontal bar 13, each rotating rod 12 is hinged to the corresponding slider 11, a rotating block 7 with a cross-shaped cross section is rotatably connected to the fixing sleeve 2, the rotating block 7 is connected to the rotating shaft 9 by a first pull rope 8.

[0023] The locking assembly includes an L-shaped plate 6 fixedly mounted on the upper surface of the fixed sleeve 2, a threaded rod 16 threadedly connected to the L-shaped plate 6, and multiple threaded holes for connecting the threaded rod 16 on the rotating block 7. The back of the side beam body 1 has an L-shaped slot. A positioning block 21 is fixedly connected to one side of the fixed sleeve 2. A vertical cavity is formed inside the fixed sleeve 2, and a limiting strip 20 with an L-shaped cross-section is slidably connected inside the vertical cavity. The limiting strip 20 and the positioning block 21 are slidably connected. A convex groove is formed on the upper surface of the fixed sleeve 2, and an I-shaped block 15 is slidably mounted inside the convex groove. The I-shaped block 15 is connected to the limiting strip 20 through a second pull rope 19. A connecting hole is formed on the I-shaped block 15. A return spring 17 is fixedly connected to the inner wall of one side of the convex groove. The return spring 17 and the I-shaped block 15 are fixedly connected. Two positioning holes are formed on both the upper and lower surfaces of the side beam body 1. Multiple symmetrically arranged positioning strips 18 are fixedly connected to the fixed sleeve 2.

[0024] During installation, first, the fixing sleeve 2 is placed on the outside of the side beam body 1, and each positioning strip 18 is slid into its corresponding positioning opening. At this time, the positioning block 21 is inserted into the slot, and the limiting strip 20 is completely located inside the positioning block 21. Then, the I-shaped block 15 is pushed to slide along the convex groove, and the return spring 17 deforms. Since the two ends of the inelastic second pull rope 19 are fixedly connected to the I-shaped block 15 and the limiting strip 20 respectively, under the transmission action of the second pull rope 19, the limiting strip 20 will slide relative to the fixing sleeve 2. When the limiting strip 20 and the positioning block 21 slide relative to each other, the upper end of the L-shaped limiting strip 20 will move to the outside of the positioning block 21 and be inserted into the L-shaped slot. The surfaces of each side of the limiting strip 20 are in close contact with the inner walls of each side of the slot, which can effectively prevent the positioning block 21 from separating from the side beam body 1. Then, rotate the threaded rod 16 so that it passes through the L-shaped plate 6 and is threadedly connected to the round hole, which can prevent the I-shaped block 15 from moving. In this way, the fixing sleeve 2 can be firmly installed together with the side beam body 1. At this time, the threaded rod 16 does not contact the rotating block 7.

[0025] In this invention, after the fixing sleeve 2 is securely installed together with the side beam body 1, the external connector is first placed in the two openings 3 and in contact with the upper and lower surfaces of the two openings 3 respectively, causing the rotating block 7 to rotate. Since the two ends of the first pull rope 8 are respectively wound around the rotating shaft 9 and the rotating block 7, and the first pull rope 8 is slidably connected to the fixing sleeve 2, the first pull rope 8 can be wound up during the relative rotation of the rotating block 7 and the side beam body 1. Under the transmission action of the inelastic first pull rope 8, the rotating shaft 9 will rotate in the mounting cavity 10 and unwind the first pull rope 8. Since the two ends of the torsion spring are respectively fixedly connected to the inner wall of the mounting cavity 10 and the rotating shaft 9, the torsion spring deforms, and the two rotating rods 12 rotate during the process. In the middle, the two sliders 11 will slide, and the two horizontal bars 13 will slide vertically in the mounting cavity 10 at the same time, and the distance between the two horizontal bars 13 will decrease. Since the two ends of each fixed rod 22 are fixedly connected to the corresponding horizontal bars 13 and the sliders 14 respectively, under the transmission action of the fixed rod 22, the two sliders 14 will slide relative to the fixed sleeve 2 at the same time, and the distance between the two adjusting plates 4 will decrease. After each limit block 5 moves, it will engage with the corresponding slot on the external connector. Finally, the threaded rod 16 will be rotated again so that it passes through the round hole and is threadedly connected to the corresponding threaded hole, which can realize the rapid positioning of the side beam body 1. After that, welding can be carried out. The positioning process takes less time and is conducive to improving the welding efficiency.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
