Description

[0002] The excavator articulated frame is one of the important components connecting the excavator upper frame and the cab. It is usually made of sheet metal. During the production process of the excavator bracket, the various components need to be welded into a whole. Figure 1 This is a structural diagram of the articulated frame. Because the articulated frame is a special-shaped part as a whole, including the pillow, horizontal part, legs and other parts, these parts need to be assembled and welded separately. In the actual welding and assembly process, due to factors such as fixed angle, position, and size design errors, the relative distance and angle between the mounting holes on the two legs and the horizontal sheet metal will change after welding, that is, the product structure will be deformed, and ultimately the special-shaped parts cannot be accurately installed on the equipment after welding.

[0003] In the related art, the welding of special-shaped parts of such articulated frames usually requires the participation of multiple workers, and auxiliary measurements are performed using tools such as brackets, levels, and measuring instruments to verify whether the articulated frames can be used normally. This method requires more labor costs, and the efficiency of verification and welding is low. Utility Model Content

[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0024] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0025] Figure 1 It is a schematic diagram of the structure of an articulated frame, including a pillow 11, a horizontal portion 12, a first leg 13 and a second leg 14. The pillow 11 is used to be welded to one end of the horizontal portion 12, and the first leg 13 and the second leg 14 are used to be welded to the other end of the horizontal portion 12. The first leg 13 and the second leg 14 are special-shaped parts, and are designed with a certain curvature, and foot pads need to be welded at the bottom of the legs, that is, the first foot pad 15 is welded to the bottom of the first leg 13, and the second foot pad 16 is welded to the second leg 14. In addition, sheet metal parts need to be welded to the first leg 13 and the second leg 14, and the sheet metal parts are used to be installed on other equipment of the excavator. Because mounting holes and pins need to be opened on the sheet metal parts, when the two legs and the horizontal portion 12 are placed and fixed, the welded articulated frame will not be able to be installed on specific parts of the excavator.

[0026] Based on the above-mentioned articulated frame, the embodiment of the present application provides an articulated frame calibration tool, see Figure 2As shown, the articulated frame verification tool specifically includes a mounting bracket 20, a pillow frame 30 and an alignment plate 40. The articulated frame 10 is arranged on the mounting bracket 20, wherein the horizontal portion 12 of the articulated frame 10 is located on the mounting platform 22 of the mounting bracket 20, and one end of the first leg 13 and the second leg 14 of the articulated frame 10 is welded to the horizontal portion 12, and the other end is mounted on the bottom frame 23 of the mounting bracket 20.

[0027] Combination Figure 1 and Figure 4 A plurality of mounting holes are provided on the sheet metal part welded on the first leg 13, that is, Figure 1 The first mounting hole 121, the second mounting hole 131 and the third mounting hole 132 are provided in the alignment plate 40. An alignment pin 141 is provided on the sheet metal to which the second leg 14 is welded. Therefore, a first alignment hole 41 matching the first mounting hole 121, a second alignment hole 42 matching the second mounting hole 131, and a third alignment hole 43 matching the alignment pin 141 are provided on the alignment plate 40. Optionally, because the third mounting hole 132 is also provided on the first leg 13, a fourth alignment hole 44 matching the third mounting hole 132 can also be provided on the alignment plate 40. During installation, the first leg 13 and the second leg 14 can be fine-tuned according to the position of the alignment hole 41 on the alignment plate 40, and the three alignment holes can be aligned and embedded with the three mounting holes and the alignment pin 141 during installation. In some embodiments, the first alignment hole 41 and the fourth alignment hole 44 are arranged in the same vertical direction, and the fourth alignment hole 44 and the second alignment hole 42 are arranged at the same horizontal height.

[0028] After the alignment holes are completely matched with the mounting holes and alignment pins 141 on each leg, the pins can be inserted to fix the alignment plate 40 relative to the two legs, so as to ensure that the legs will not deviate and affect subsequent installation.

[0029] The installation of the pillow frame 30 and the horizontal portion 12 requires a precise angle, and an unreasonable bending angle will also affect the installation of the entire hinged frame 10. In this embodiment, the pillow frame 30 is installed on the mounting table 22, and the pillow portion 11 of the hinged frame 10 is fixedly installed on the pillow frame 30, and the connection between one end of the pillow portion 11 and the horizontal portion 12 is a welding point. The design of the pillow frame 30 can ensure the welding bending angle and improve the welding accuracy.

[0030] See also Figure 3 and Figure 4As shown, the alignment plate 40 is located between the first leg 13 and the second leg 14 and is perpendicular to the base frame 23. Since the first leg 13 and the second leg 14 are welded in two different directions toward the horizontal portion 12, the alignment plate 40 is designed to include a first alignment bracket 45, a second alignment bracket 46, a mounting plate and other structures. The second alignment bracket 46 is connected to the first alignment bracket 45 and is located on a different plane, that is, the second alignment bracket 46 is set to a bent structure, and the third alignment hole 43 on the second alignment bracket 46 matches the alignment pin 141 on the second leg 14.

[0031] In some other embodiments, a bottom support bracket 50 may be further provided below the alignment plate 40. Since the installation height of the alignment plate 40 is higher than the base frame 23, in order to facilitate design and material solution, the alignment plate 40 may be installed in mid-air, and then a bottom support bracket 50 may be provided below the alignment plate 40. The bottom of the bottom support bracket 50 is fixedly installed on the base frame 23, and the top is connected to the alignment plate 40, which is also convenient for disassembly.

[0032] Combination Figure 3 and Figure 5 As shown, a first pad 15 for welding is provided at the end of the first leg 13, and a plurality of first fixing holes 151 are provided on the first pad 15. Similarly, a second pad 16 for welding is provided at the end of the second leg 14, and a plurality of second fixing holes 161 are provided on the second pad 16. The two legs need to be fixed to the mounting bracket 20, so a pad 21 for carrying the first pad 15 and the second pad 16 is respectively installed on the bottom frame 23. The first pad 15 is aligned and installed with the pad 21 through the first fixing holes 151 and the connecting piece. Figure 4 In the enlarged view of the middle A, the first fixing hole 151 can be provided with multiple parts, some of which are installed on the cushion block 21 by screws 211, and the other parts are fixed by pins or latches, which is convenient for disassembly and installation. Specifically, a protruding pin 212 can be provided on the cushion block 21, and the pin 212 matches the first fixing hole 151. During installation, the pin 212 is first inserted into the first leg 13 for alignment, and then fixed with the screw 211. The second fixing hole 161 on the second foot pad 16 is connected to the cushion block 21 in the same way, and is aligned and fixed by pins and / or screws.

[0033] In addition, in order to ensure the progress of welding and the verification of material size, at least two groups of distance detection holes 123 can be opened in the horizontal part 12. Correspondingly, the detection plate 24 is installed on the mounting table 22, and at least two groups of detection positioning rods 241 for matching the distance detection holes 123 are provided on the detection plate 24. The distance between the two groups of detection positioning rods 241 is set according to actual needs. Because the distance between the two distance detection holes 123 is a strict design requirement, when there is an error in the length or opening of the horizontal part 12, it can be verified in advance to avoid material waste due to failure to install after welding.

[0034] Working principle: The structure first places the horizontal section 12 constituting the articulated frame on the mounting table 22, especially aligns the distance detection hole 123 opened on the horizontal section 12 with the detection positioning rod 241 on the detection plate 24, and then embeds the horizontal section 12 into it after ensuring the size matches, and then assembles the two legs and the sheet metal parts to be welded to the horizontal section 12, and then matches the positioning plate 40 with the mounting holes and alignment pins 141 on each leg. After the match is successful, the bottom of the two legs is aligned and fastened with the cushion block 21, and the bottom bracket 50 is erected and installed under the alignment plate 40. For the pillow 11 of the articulated frame 10, the pillow frame 30 is installed at the position of the horizontal part 12, and the pillow 11 is fixedly installed on the pillow frame 30, ensuring the welding bending angle, and then performing the subsequent welding process. The tooling assembles multiple sections of loose-part structures separately, and at the same time cooperates with the mounting bracket, pillow frame and alignment plate with alignment holes to perform positioning and matching, ensuring the assembly accuracy of each loose part and improving the welding accuracy and efficiency of the articulated frame.
