TECHNICAL FIELD
[0001] The utility model belongs to welding tool technical field, especially relate to tractor support welding tool. BACKGROUND
[0002] In modern mechanical manufacturing industry, tractor support as the key component of agricultural machinery, its manufacturing quality and efficiency are directly related to the overall performance and production cost of agricultural machinery. The structure of tractor support is complex, involving a large number of welding work, which requires high precision and consistency in the processing process. Traditionally, these welding operations are mostly completed by manual work, but manual welding not only has low efficiency, but also is difficult to ensure the consistency of welding quality. Therefore, with the continuous development of automation technology, the application of manipulator in tractor support processing is increasingly widespread.
[0003] The manipulator has shown great advantages in welding operation due to its high precision, high efficiency and repeatable programming characteristics. However, when using the manipulator for tractor support welding, a key problem is how to ensure that the manipulator can accurately find and position each welding point. This requires complete positioning of the tractor support, and the welding tool is an important auxiliary tool to achieve this goal. The design of welding tool needs to meet the precise positioning requirements to ensure that the manipulator can accurately complete each welding action in the welding process.
[0004] However, most of the welding tools on the market only have pure positioning function and lack mobility. This means that during the welding process, the manipulator's travel is completely relied on to switch different welding points. This not only puts high requirements on the travel of the manipulator, but also in the welding of large size or complex structure tractor support, the travel limit of the manipulator often becomes the key factor restricting the processing efficiency and flexibility.
[0005] In addition, the size and axis number of the manipulator directly determine its travel range and working capacity. For tractor support that needs to move in a large range or weld at multiple points, a manipulator with large travel and multiple axes becomes a necessary choice. However, the procurement and maintenance cost of such manipulator is usually high, which brings not small economic pressure to manufacturing enterprises.
[0006] Therefore, designing an auxiliary welding tool that can move the tractor support becomes an effective way to solve the above problems, improve welding efficiency and reduce cost. SUMMARY

[0018] To better understand this utility model, the following is in conjunction with... Figures 1-2 The embodiments of this utility model will be explained in detail below.
[0019] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, and down".
[0020] This utility model discloses a welding fixture for a tractor bracket, comprising a base 1 on which a CNC turntable 2 is mounted. The turntable 2 is capable of precise 360° rotation in a horizontal plane, facilitating the adjustment of the welding angle of the tractor bracket. Two first electric lead screws 3 are symmetrically mounted on both sides of the top of the CNC turntable 2, each equipped with a first lead screw female seat 4. A CNC four-axis 5 and a tailstock 6 are fixedly connected to these two first lead screw female seats 4, which together constitute the support and positioning structure of the tractor bracket.
[0021] A mounting bracket 7 is installed between the CNC four-axis 5 and the tailstock 6 to secure the tractor bracket. The mounting bracket 7 is equipped with several fixing mechanisms 8, which can be locking bolts, clips, or other forms of clamping devices to ensure the stability and accuracy of the tractor bracket during the welding process.
[0022] In addition, a linear guide rail 9 is mounted on the base 1 above the CNC turntable 2, and a second electric lead screw 10 is installed inside the linear guide rail 9. A second lead screw socket 11 is mounted on the second electric lead screw 10, and a robotic arm 12 is mounted on the second lead screw socket 11. The robotic arm 12 is used to perform welding operations and can move precisely along the Y-axis under the guidance of the linear guide rail 9.
[0023] In order to reduce the burden of the first electric screw 3, the top of the numerical control turntable 2 is provided with a plurality of guide rods 13 corresponding to the first electric screw 3 on both sides, and a lifting frame 14 is slidably connected to each side of the guide rod 13. The first screw female seat 4, the numerical control four-axis 5 and the tailstock 6 are fixedly connected with the lifting frame 14. In this way, when the first electric screw 3 drives the first screw female seat 4 to move up and down, the lifting frame 14 will be lifted, thereby driving the numerical control four-axis 5 and the tailstock 6 and the tractor support fixed thereon to move up and down.
[0024] Meanwhile, a support beam 15 is arranged between the guide rods 13 on each side, and the first electric screw 3 is connected with the support beam 15. The arrangement of the support beam 15 enhances the structural stability of the tooling, so that the lifting movement is more stable and reliable.
[0025] A guide sleeve 16 is arranged on the lifting frame 14 and matched with the guide rod 13, so as to ensure that the lifting frame 14 slides on the guide rod 13 more smoothly and accurately.
[0026] The fixing mechanism 8 comprises a hydraulic oil cylinder 17, a plurality of vertical plates 18 are arranged on the fixing frame 7, and a hydraulic oil cylinder 17 with the piston end inward is arranged on each vertical plate 18. A profiling pressing block 19 corresponding to the tractor support is arranged on each hydraulic oil cylinder 17, so as to ensure that the locking effect is more closely and uniformly.
[0027] A hydraulic oil cylinder 17 is arranged in the fixing frame 7, and an oil tank and an oil pump are arranged on the base 1. A through-hole slip ring is arranged between the rotating end of the numerical control four-axis 5 and the fixing frame 7, the through-hole slip ring connects the oil tank and the oil pump and the oil pipeline (since the through-hole slip ring connecting the oil pipeline and the oil tank and the oil pump is a mature prior art, which is easily realized by those skilled in the art, therefore the connection of these structures is not shown in the drawings), so as to ensure that the hydraulic oil cylinder 17 can work normally and stably.
[0028] A plurality of adjusting foot supports 20 are symmetrically arranged on the bottom of the base 1, so as to adjust the height and levelness of the tooling according to actual needs.
[0029] The use mode and principle of the utility model are as follows:
[0030] The tractor support is placed on the fixing frame 7, and is locked and fixed by the fixing mechanism 8. According to the welding requirement, the welding angle of the tractor support is adjusted by the numerical control turntable 2. The first electric screw 3 is started, the numerical control four-axis 5 and the tailstock 6 and the tractor support fixed thereon are driven to move up and down by the lifting frame 14, and are adjusted to the appropriate welding height.
[0031] Start the second electric screw 10, through the movement of the mechanical arm 12 on the linear guide 9, adjust the welding gun to the position to be welded. Start the welding equipment and start the welding work. During the welding process, the working state of the numerical control turntable 2, the first electric screw 3 and the second electric screw 10 can be adjusted as required to realize precise welding in multiple angles and multiple positions.
[0032] After the welding is completed, the welding equipment is turned off, the fixing mechanism 8 is loosened, and the tractor support is taken off from the fixing frame 7.
