[0036] Please see Figures 1 to 2 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0037] This utility model provides a welding fixture for flanged tiles, such as... Figure 1 and Figure 2 As shown, the flanged bearing welding fixture includes a positioning seat 10, a first thrust plate positioning module 20, and a second thrust plate positioning module 30. The positioning seat 10 has a curved groove for placing the bearing 100. Two bearing positioning modules 12 are located on the top of the positioning seat 10, respectively positioned on the left and right sides of the curved groove. These two bearing positioning modules 12 are used to press the bearing 100 into the curved groove. The first thrust plate positioning module 20 includes a first thrust plate pressure plate 21, which is connected to a first adjusting device. The first adjusting device 22 is disposed on the front side wall of the positioning seat 10. The first adjusting device 22 can adjust the first thrust plate pressure plate 21 to move closer to the front side wall of the positioning seat 10 and to move away from the front side wall of the positioning seat 10. The second thrust plate positioning module 30 includes a second thrust plate pressure plate 31, which is disposed on the rear side wall of the positioning seat 10 through the second adjusting device 32. The second adjusting device 32 can adjust the second thrust plate pressure plate 31 to move closer to the rear side wall of the positioning seat 10 and to move away from the rear side wall of the positioning seat 10.
[0038] The beneficial effects of the flanged bearing welding fixture of this utility model are as follows: In use, the bearing 100 is first placed into the curved groove on the positioning seat 10, and then the bearing positioning modules 12 located on the left and right sides of the curved groove 11 of the positioning seat 10 press the left and right ends of the bearing 100 respectively to press the bearing 100 into the curved groove. Then, a thrust plate 200 is connected to one side of the bearing (the thrust plate has a protrusion, and the side of the bearing has a groove that matches the protrusion. The thrust plate is first engaged with the bearing by the cooperation of the protrusion and the groove). Then, the first thrust plate pressure plate 21 is adjusted to move closer to the first adjusting device 22. The front sidewall of the positioning seat 10 moves to clamp the thrust plate 200 between the first thrust plate pressure plate 21 and the front sidewall of the positioning seat 10, thus positioning the thrust plate. Then, another thrust plate 200 is engaged with the other side of the bearing bush 100. Next, the second thrust plate pressure plate 31 is adjusted by the second adjusting device 32 to move closer to the rear sidewall of the positioning seat 10, clamping the thrust plate between the second thrust plate pressure plate 31 and the rear sidewall of the positioning seat 10. Welding can then be performed at the connection between the thrust plate and the bearing bush. After welding, the bearing bush positioning module is removed, and the welded flanged bearing is taken out of the positioning seat. Compared with existing technologies, the flanged bearing welding fixture of this invention can greatly improve the stability of flanged bearing welding, thereby improving the welding quality, reducing labor intensity, and saving labor costs.
[0039] Furthermore, such as Figure 1 As shown, in this embodiment, the bearing positioning module 12 includes a bearing pressure block 121. The bearing pressure block 121 has a waist-shaped hole (not shown in the figure). The waist-shaped hole extends along the left and right direction of the positioning seat 10. A fastening screw 122 is inserted into the waist-shaped hole and is threadedly connected to the positioning seat 10, thereby fixing the bearing pressure plate 121 to the top of the positioning seat 10. With this configuration, when placing the bearing bush 100 into the curved groove, loosening the fastening screw 122 allows the pressure block 121 to move relative to the fastening screw 122 in the left-right direction along the positioning seat 10. By moving the pressure block 121 away from the curved groove, the pressure block 121 is removed from above the curved groove, making it easier for the bearing bush 100 to be placed into the curved groove from above. After the bearing bush 100 is placed into the curved groove, the pressure block 121 is moved closer to the curved groove, causing the pressure block 121 to protrude a certain distance into the curved groove, so that the two pressure blocks 121 press against the left and right ends of the bearing bush 100 respectively. Then, the fastening screw 122 is tightened, thereby achieving the positioning of the bearing bush 100 in the curved groove. The structure is simple and easy to adjust.
[0040] Furthermore, such as Figure 2As shown, in this embodiment, the first adjusting device 22 includes a first adjusting screw 221 fixedly mounted on the front sidewall of the positioning seat 10. A first thrust plate 21 is slidably mounted on the first adjusting screw 221. A first adjusting nut 2210 is threaded onto the first adjusting screw 221. The first adjusting nut 2210 is located on the outer side of the first thrust plate 21, i.e., away from the front sidewall of the positioning seat, and abuts against the first thrust plate 21. When adjusting the first thrust plate 21 to move closer to the front sidewall of the positioning seat 10, the first adjusting nut 2210 is screwed on, causing the first adjusting nut 2210 to press against the first thrust plate 21 and move along the first adjusting screw 221, thereby clamping the thrust plate. After welding is completed, the first adjusting nut 2210 is loosened, and the first thrust plate 21 is moved away from the front sidewall of the positioning seat 10 to release the thrust plate.
[0041] Specifically, such as Figure 1 As shown, in this embodiment, the first thrust plate 21 is provided with a second waist-shaped hole 210, which extends in the vertical direction, and the first adjusting screw 221 passes through the second waist-shaped hole 210.
[0042] Furthermore, after welding is completed, in order to facilitate the movement of the first thrust plate pressure plate 21 away from the front sidewall of the positioning seat 10, that is, to facilitate the release of the thrust plate by the first thrust plate pressure plate 21, preferably, as follows: Figure 2 As shown, in this embodiment, a spring 222 is sandwiched between the first thrust plate 21 and the front sidewall of the positioning seat 10. With the spring 222, when the first thrust plate 21 clamps the thrust plate 200, the spring 222 is compressed and stores energy. When the welding is completed and the first thrust plate 21 needs to be released, as the first adjusting nut 2210 is loosened, moving away from the first thrust plate 21, the spring 222 applies an outward pushing force to the first thrust plate 21, thus pushing the first thrust plate 21 outward, i.e., away from the front sidewall of the positioning seat 10.
[0043] Furthermore, in order to facilitate the turning of the first adjusting nut 2210, in this embodiment, a turning handle (not shown in the figure) is provided on the first adjusting nut 2210.
[0044] Furthermore, to prevent the first thrust plate pressure plate 21 from causing indentations or scratches on the thrust plate 200 when clamping the thrust plate 200, preferably, as follows: Figure 2 As shown, in this embodiment, a flexible pressure block 23 is provided on the first thrust plate 21, which is used to press the thrust plate. Preferably, in this embodiment, the flexible pressure block 23 is made of nylon.
[0045] Specifically, the second adjusting device 32 has the same structure and working principle as the first adjusting device 22, so the second adjusting device will not be described in detail here.
[0046] In summary, the welding fixture for flanged tiles of this invention can greatly improve the stability of flanged tile welding, thereby improving the welding quality, while also reducing labor intensity and saving labor costs. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
