[0002] During the welding process of shaft rollers, precise welding operation is crucial to ensure the quality and performance of the shaft rollers.

[0003] Some existing welding auxiliary devices, such as a welding auxiliary tool with announcement number CN219336656U and a pipeline welding auxiliary device with announcement number CN220462829U, provide convenience for welding operations to a certain extent and have a distance adjustment function. However, the obvious limitation of these devices is that their adjustment distance is relatively short.

[0004] In actual production, we often encounter situations where the diameters of shaft rollers vary greatly. Since the above-mentioned devices cannot achieve a wide range of distance adjustment, they are difficult to meet the welding auxiliary needs between shaft rollers of different diameters. This means that when facing welding tasks with large differences in shaft roller diameters, it may be necessary to replace a variety of auxiliary devices of different specifications or adopt complex temporary adjustment measures, which not only increases equipment costs and operational complexity, but also reduces the efficiency and accuracy of welding production, and cannot well meet the requirements of diversification and efficiency of modern shaft roller welding processing. Therefore, another shaft roller welding auxiliary device is provided to solve the above technical problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In this embodiment, the front, rear, left, right, top and bottom are represented by Figure 1 Describes the datum surface. Figure 1-Figure 6 , the utility model provides a technical solution:

[0023] A shaft-roller welding auxiliary device comprises a base 1, two I-shaped rails A11 are fixedly installed on the upper surface of the base 1, two right-angled triangular seats 2 with adjustable distances are slidably installed between the two I-shaped rails A11, a carrier plate 3 is slidably installed on the inclined surface of the right-angled triangular seat 2, a vertical plate 4 is fixedly installed on the inclined surface of the right-angled triangular seat 2, a hydraulic telescopic rod 41 is fixedly installed between the vertical plate 4 and the carrier plate 3 on the same side, a carrier 5 is fixedly installed on the upper surface of the base 1, the carrier 5 is located between the two right-angled triangular seats 2, and a plurality of mounting grooves 31 are equidistantly provided on the upper surface of the carrier 5 and the upper surface of the carrier plate 3, and auxiliary wheels 33 are rotatably installed in the mounting grooves 31;

[0024] It should be noted that, combined with Figure 1 and Figure 2 As shown, two fixing plates 12 are fixedly installed on the upper surface of the base 1, and a positive and negative thread bidirectional screw 13 is rotatably installed between the two fixing plates 12. A driving motor 14 is fixedly installed on the upper surface of the base 1, and the output end of the driving motor 14 is fixedly connected to the right end of the positive and negative thread bidirectional screw 13. Two right-angled triangular seats 2 are respectively screwed on the positive and negative thread outer surfaces of the positive and negative thread bidirectional screw 13;

[0025] When the auxiliary device is used for welding auxiliary lifting of a shaft roller with a smaller diameter, the two hydraulic telescopic rods 41 are first retracted to drive the carrier plate 3 on the same side to slide down, thereby driving the auxiliary wheels 33 at the corresponding position to move closer to the carrier frame 5, thereby shortening the spacing between the auxiliary wheels 33 on both sides. After that, the two right-angled triangle seats 2 are driven to move synchronously toward the carrier frame 5 by means of the positive and negative bidirectional screws 13, further shortening the spacing between the auxiliary wheels 33 on both sides, so that the device as a whole can adapt to the welding auxiliary lifting of shaft rollers with smaller right angles. After adjusting to a suitable position, the shaft roller is placed above the auxiliary wheels 33 of the carrier frame 5 for support, and the auxiliary wheels 33 on the carrier plate 3 are used to auxiliary support both sides of the shaft roller. When welding auxiliary lifting of shaft rollers with larger right angles is performed, the direction operation is performed to increase the spacing between the auxiliary wheels 33 on both sides. Compared with the prior art, the device broadens the adjustment range of the auxiliary wheels 33 on both sides, making it more applicable, and can adapt to shaft rollers with a wider diameter range, providing effective assistance for the auxiliary lifting operation of the shaft rollers.

[0026] Combination Figure 5 and Figure 1 As shown, two slide grooves 21 are provided through the right surface of the right-angled triangle seat 2. After the right-angled triangle seat 2 is mounted on the I-shaped rail A11 through the slide grooves 21, the inner surface of the slide grooves 21 fits with the inner surface of the corresponding I-shaped rail A11, so that the right-angled triangle seat 2 can be slidably installed on the base 1.

[0027] Combination Figure 5 and Figure 3As shown, two I-shaped rails B22 are fixedly installed on the inclined surface of the right-angle triangle seat 2, and two J-shaped plates 36 are fixedly installed on the side of the carrier plate 3 close to the hydraulic telescopic rod 41. After the J-shaped plate 36 is sleeved on the adjacent I-shaped rail B22, a sliding connection is achieved between the J-shaped plate 36 and the adjacent I-shaped rail B22, thereby realizing the sliding installation of the carrier plate 3 on the inclined surface of the right-angle triangle seat 2.

[0028] In addition, combined Figure 5 and Figure 2 As shown, a long rod rotating shaft 32 is rotatably installed in both the carrier plate 3 and the carrier frame 5, and bearings are provided at both ends of the long rod rotating shaft 32. The long rod rotating shaft 32 at the corresponding position is rotatably connected with the carrier plate 3 and the carrier frame 5 through the bearings. The auxiliary wheels 33 are sleeved on the outer surfaces of the adjacent long rod rotating shafts 32, and the outer surfaces of the auxiliary wheels 33 are penetrated by T-shaped bolt grooves 34. Bolts 35 are threadedly installed between the bolt grooves 34 and the connected long rod rotating shafts 32. After the bolts 35 are unscrewed, the long rod rotating shaft 32 is pulled out of the carrier frame 5 or the carrier plate 3, and the auxiliary wheels 33 can be replaced to prevent the auxiliary wheels 33 from being excessively worn and continued use affecting the auxiliary lifting effect.

[0029] Finally, when the shaft roller is lifted by the auxiliary wheel 33, in order to facilitate the rotation of the shaft roller to adjust the welding surface, Figure 2 As shown, a stepper motor 51 is fixedly installed on the front surface of the carrier 5, and the output end of the stepper motor 51 is fixedly connected to the front surface of the adjacent long rod rotating shaft 32. In this way, the stepper motor 51 can be used to drive the long rod rotating shaft 32 in the carrier 5 to rotate, thereby driving the auxiliary wheel 33 at the corresponding position to rotate, and finally achieving the purpose of driving the shaft roller to rotate to complete the welding surface adjustment.
