After the bearing seat member 1 and the fixing block 2 are welded, a bearing is generally mounted in the bearing seat member 1 to ensure that the stability of clamping the bearing seat member 1 is best. If the bearing is welded after the bearing housing part 1 is mounted, it is necessary to lock the bearing in the bearing housing part 1 to prevent the second clamping assembly 8 from rotating after clamping the bearing housing part 1.
The lifting assembly also includes a sliding bracket 92 and a telescopic rod 93; the sliding support 92 is arranged on the support 4 in a sliding manner along the vertical direction, the hydraulic power system 94 is fixed on the sliding support 92, and the sliding support 92 is connected with the telescopic rod 93; the bracket 4 is provided with a third power member 91 for controlling the expansion and contraction of the telescopic rod 93.
The third power member 91 controls the extension or shortening of the telescopic rod 93, thereby adjusting the height of the sliding bracket 92, and thus the axial height of the bearing member 1.
The working principle of the invention is that the first clamping assembly 7 clamps the fixed block 2, and when the sliding seat 52 moves towards the first clamping assembly 7, the conical head 56 presses the inclined surface 70 of the sliding support plate 71 to separate the two sliding support plates 71 to two sides. The second clamping assembly 8 is inserted into the bearing seat component 1 to clamp the bearing seat component 1; the lifting assembly adjusts the height of the bearing component 1, and then welds the bearing component 1 and the fixed block 2; after the welding is completed, the second clamping assembly 8 is retracted, the bearing seat is taken out integrally, and the sliding seat 52 moves in a direction away from the first clamping assembly 7, so that the two sliding support plates 71 are close to each other.
In summary, in the present invention, the fixing block 2 is clamped between the first clamping plate 74 and the second clamping plate 77 to form a stable structure; the second clamping plate 77 has an i-shape, and can form a limiting structure on the positioning plate 75 to prevent the second clamping plate 77 from being offset in the vertical direction and ensure the normal sliding of the second clamping plate 77; the heights of the first clamping plate 74 and the second clamping plate 77 are smaller than the height of the fixed block 2, so that the influence on the upper surface welding of the fixed block 2 is avoided, and the best welding quality is ensured.
In the present invention, when the sliding seat 52 moves in the direction toward the first clamping assembly 7, the tapered head 56 presses the inclined surface 70 of the sliding support plate 71 to separate the two sliding support plates 71 to both sides, thereby realizing the adjustment of the distance between the two fixed blocks 2; the operator reads the scale value line 30 according to the scale value line 30 pointed by the indication line 50, thereby obtaining the distance value between the two sliding support plates 71, and calculating the distance between the two fixed blocks 2, so that the fixed blocks 2 reach the preset position, and the welding quality is improved. In a state in which the slide block 52 is moved in a direction away from the first clamping assembly 7, the gear 61 controls the slide blocks 62 to move in a direction toward the first clamping assembly 7, and the two first clamping assemblies 7 are clamped between the two slide blocks 62, thereby achieving that the two slide support plates 71 approach each other; the sliding block 62 always abuts against the sliding support plate 71, and the sliding block 62 and the sliding seat 52 clamp the sliding support plate 71 to prevent the sliding support plate 71 from moving during welding.
In the invention, the second clamping assembly 8 can clamp the bearing seat parts 1 with different inner diameter sizes, so that the use comfort of the equipment is improved; the supporting ball 84 is in point contact with the inner peripheral surface of the bearing seat part 1, and under the action of gravity, the bearing seat part 1 realizes automatic adjustment so as to ensure that the axis of the bearing seat part 1 is parallel to the axis of the hydraulic main pipe 81; the hydraulic branch pipes 82 are mutually communicated through the hydraulic main pipe 81, so that the pressures in the hydraulic branch pipes 82 are equal everywhere, the extension length of the piston assembly 83 is equal, the pressures of each supporting piece on the inner periphery of the bearing seat component 1 are equal, and the supporting effect of the bearing seat component 1 is stable;
In the invention, the axis of the hydraulic main pipe 81 is overlapped with the axial direction of the bearing seat part 1, and the height of the hydraulic main pipe 81 is adjusted through the lifting assembly, so that the distance between the axis of the bearing seat part 1 and the sliding support plate 71 is realized, thereby being convenient for calculating the distance between the axis of the bearing seat part 1 and the upper surface of the fixed block 2, and realizing the accurate control of the height during welding.
