[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] Please see Figure 1-3 This utility model provides a technical solution for a welding fixture for quickly adjusting the bearing of an agricultural machinery base: a welding fixture for quickly adjusting the bearing of an agricultural machinery base includes a welding seat 1, a three-jaw chuck 2 installed on the welding seat 1, a welding plate 3 provided at the top of the welding seat 1 and the three-jaw chuck 2, and a manual clamping device 4 symmetrically installed at both ends of the welding plate 3.
[0023] In this embodiment, a three-jaw chuck 2 is provided below the welding plate 3 to facilitate clamping of the bearing 8 to be welded. Two sets of manual clamps 4 are provided at both ends of the welding plate 3 to facilitate clamping of the agricultural machinery parts to be welded, ensuring the stability of the welded parts and preventing them from shifting. This tooling has a simple structure, is easy to operate, and can quickly and accurately position and fix the workpiece to be welded, thereby improving welding efficiency and quality.
[0024] Furthermore, a groove is provided inside the welding seat 1, and the bottom of the three-jaw chuck 2 is fixedly installed in the groove.
[0025] In this embodiment, a C-shaped welding seat 1 is provided, a three-jaw chuck 2 is installed in the C-shaped groove, a welding plate 3 is mounted on the top of the welding seat 1, and the three-jaw chuck 2 is installed directly below the welding plate 3, so that the bearing 8 placed on the welding plate 3 is clamped and tightened by the three-jaw chuck 2.
[0026] Typically, a three-jaw chuck 2 includes: a disc body 21, the bottom of which is fixedly connected to a welding seat 1, three sets of jaws 22 slidably connected on the disc body 21, a locking bolt 23 located below the jaws 22 on the disc body 21, the locking bolt 23 being drivenly connected to the three sets of jaws 22, and a clamping groove 24 being provided at the center position between the three sets of jaws 22 on the disc body 21.
[0027] In this embodiment, the three-jaw chuck 2 includes a structural disc body 21, jaws 22, and a locking bolt 23. The locking bolt 23 has a bolt groove. By rotating the locking bolt 23 clockwise with an external wrench, the three sets of jaws 22 are driven to move inward through the internal transmission structure to clamp the bearing 8. The three-jaw chuck 2 is a common tooling fixture, well known to those skilled in the art. The specific internal transmission structure will not be described in detail here. It clamps the bearing 8 to prevent the bearing 8 from shaking during processing.
[0028] Specifically, the top of the welding seat 1 is provided with several sets of sliding pillars 5 around its perimeter, and the welding plate 3 is provided with sliding grooves at the sliding pillars 5. The several sets of sliding pillars 5 pass through the welding plate 3 through the sliding grooves.
[0029] In this embodiment, sliding columns 5 are provided around the top of the welding base 1, and the welding plate 3 is sleeved on the sliding columns 5. The welding plate 3 slides up and down under the action of the sliding columns 5, thereby facilitating the adjustment of the height of the welding plate 3. This is suitable for welding the base bearings of agricultural machinery parts of different sizes. Multiple sets of sliding columns 5 ensure that the welding plate 3 slides stably up and down without lateral displacement, thus preventing inaccurate alignment.
[0030] In addition, an adjusting bolt 6 is provided on one side of the sliding column 5 of the welding plate 3. The adjusting bolt 6 has a threaded groove at the sliding column 5. The threaded groove and the adjusting bolt 6 are adapted to each other. The adjusting bolt 6 extends through the threaded groove to the top of the welding plate 3.
[0031] In this embodiment, by opening a threaded groove in the welding plate 3, the adjusting bolt 6 can be rotated downwards through the threaded groove to freely adjust the height as needed. Rotating the adjusting bolt 6 downwards lifts the welding plate 3, and the welding plate 3 is kept level by adjusting the adjusting bolts 6 at both ends simultaneously.
[0032] It should be noted that a bearing hole 7 is provided at the middle position of the top of the welding plate 3, and the bearing hole 7 corresponds to the position of the clamping groove 24.
[0033] In this embodiment, the welding plate 3 has a bearing hole 7, which makes it easy to put the bearing 8 to be welded into the bearing hole 7. The bearing hole 7 corresponds to the clamping groove 24, which makes it easy to keep the bearing 8 in the clamping groove 24 and to clamp the bearing 8.
[0034] The working principle and usage process of this utility model are as follows: After the utility model is installed, the bearing 8 to be welded is placed into the bearing hole 7 and inserted into the clamping groove 24. The locking bolt 23 is turned clockwise by the external wrench, and the three sets of jaws 22 are moved inward by the internal transmission structure to clamp the bearing 8. Then, the agricultural machinery part 9 is aligned with the bearing 8, and the agricultural machinery part 9 is pressed by the manual clamping devices 4 on both sides. Then, the bearing 8 and the agricultural machinery part 9 are welded and fixed by the external welding device. After the welding is completed, the manual clamping device 4 and the three-jaw chuck 2 are released, and the welded part is taken out. The above completes the usage process of a quick-adjusting agricultural machinery base bearing welding fixture.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
