Description

Technical Field

[0001] The utility model belongs to the technical field related to welding roller frames, and specifically relates to an adjustable welding roller frame capable of adjusting the overall height of a workpiece. Background Art

[0002] A roller frame is a welding auxiliary device, a device that drives a circular workpiece to rotate by means of the frictional force between the workpiece and the driving rollers. The roller frame includes a driving roller frame and a driven roller frame. The driving and driven roller frames are both independent and can be arbitrarily combined with one driving and multiple driven ones according to the weight, size, and length of the pipe fitting. Its working principle is that the motor drives the driving rollers through a speed reducer, and the frictional force between the driving rollers and the circular workpiece drives the workpiece to rotate for position change, realizing the welding of the horizontal positions of the inner and outer circumferential seams of the workpiece. During the use of the roller frame, in order to be well adapted to the welding equipment, it is necessary to adjust the overall height of the workpiece. The existing welding roller frames are mostly of fixed structures and are not convenient for height adjustment. The supporting rollers of the roller frame are mainly arranged near the two ends, and there is no auxiliary support in the middle position, which easily causes problems such as uneven stress and welding misalignment.

[0003] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

At positions near both ends above the main support base plate 1, a first main roller mounting seat 2 and a second main roller mounting seat 3 are respectively arranged. At the middle position below the first main roller mounting seat 2 and the second main roller mounting seat 3, a mounting seat adjustable support box 7 is fixedly arranged. Below the mounting seat adjustable support box 7, a mounting seat main support box 6 is arranged. On both sides of the mounting seat main support box 6, a main roller adjusting hydraulic cylinder 8 is installed. In the cavities of the first main roller mounting seat 2 and the second main roller mounting seat 3, a main support roller 5 is installed. An auxiliary support structure is arranged at the position between the hydraulic power box 13 and the mounting seat main support box 6 on the main support base plate 1. The auxiliary support structure includes an auxiliary support roller 14, an auxiliary mounting seat 15, an auxiliary support frame 16, a support frame mating seat 18, and an auxiliary adjusting hydraulic cylinder 20.

[0024] Among them, the auxiliary adjusting hydraulic cylinder 20 is fixedly installed on the main support base plate 1. At the upper end of the auxiliary adjusting hydraulic cylinder 20, a support frame mating seat 18 is fixedly arranged. A cavity adapted to the auxiliary support frame 16 is opened in the support frame mating seat 18. The auxiliary support frame 16 can be horizontally adjusted relative to the support frame mating seat 18, thereby realizing the adjustment of the horizontal position of the auxiliary support roller 14.

[0025] The auxiliary support frame 16 is of an L-shaped structure. The upper end of the auxiliary support frame 16 is fixedly connected to the auxiliary mounting seat 15. The auxiliary mounting seat 15 is of a U-shaped structure. The auxiliary support roller 14 is rotatably connected and installed in the auxiliary mounting seat 15. A horizontal adjustment hole 17 is machined on the auxiliary support frame 16. A fixing screw 19 is installed above the support frame mating seat 18. The fixing screw 19 is used to lock the relative position between the auxiliary support frame 16 and the support frame mating seat 18.

[0026] Two sets of four auxiliary support rollers 14 and their supporting structures are provided. The four auxiliary adjusting hydraulic cylinders 20 synchronously expand and contract. Four main roller adjusting hydraulic cylinders 8 are provided. The four main roller adjusting hydraulic cylinders 8 synchronously expand and contract to ensure the stability of up and down adjustment.

[0027] Corresponding main roller adjusting holes 4 are arranged on both the first main roller mounting seat 2 and the second main roller mounting seat 3. A gearbox 11 and a driving motor 12 are arranged at a position corresponding to one of the main support rollers 5 on the outside of the second main roller mounting seat 3 to provide power support for the driving roller.

[0028] A hydraulic oil tank, a hydraulic pump, connecting pipes, and control valves matching the main roller adjusting hydraulic cylinder 8 and the auxiliary adjusting hydraulic cylinder 20 are arranged in the hydraulic power box 13. Hoisting holes 9 are machined at positions near the four corners of the main support base plate 1. Lifting lugs 10 are installed in the hoisting holes 9 to facilitate the overall movement of the welding roller stand.

[0029] The working principle of the utility model is as follows: when welding and processing products, the workpiece is lifted onto the main roller mounting base 1 and the main roller mounting base 2 by a hoisting device, and effectively supported by the main support rollers 5. Before hoisting, the installation position of the main support rollers 5 is determined according to the diameter of the welded part. The main roller adjustment holes 4 are machined on the main roller mounting base 1 and the main roller mounting base 2, which can adjust the installation position of the main support rollers 5 to meet the welding support use requirements of workpieces with different diameter specifications. When hoisting the workpiece, the main roller adjustment hydraulic cylinders 8 and the auxiliary adjustment hydraulic cylinders 20 are in a contracted state, facilitating the hoisting operation of the workpiece;

[0030] After the workpiece is placed on the main support rollers 5, according to the support needs, the support position of the auxiliary support rollers 14 is adjusted. First, loosen the fixing screws 19, adjust the relative position of the auxiliary support frame 16 and the support frame mating seat 18, and then adjust the height by the auxiliary adjustment hydraulic cylinder 20. The auxiliary support rollers 14 are used to assist in supporting the middle section of the workpiece. When the overall height of the workpiece needs to be adjusted to match the welding equipment, the main roller adjustment hydraulic cylinders 8 are lifted and lowered synchronously to adjust the overall height position of the workpiece. Then, the auxiliary adjustment hydraulic cylinders 20 rise accordingly, and the four auxiliary adjustment hydraulic cylinders 20 are lifted and lowered synchronously;

[0031] Hoisting holes 9 are machined on the main support base plate. When moving the position of the integral moving welding roller frame, lifting lugs 10 are installed into the hoisting holes 9, and the integral position is moved in cooperation with the lifting tool and the hoisting equipment. When the position does not need to be moved, the lifting lugs 10 are removed to avoid tripping the operator;

[0032] Mounting seat main support boxes 6, mounting seat adjustable support boxes 7, and main roller adjustment hydraulic cylinders 8 are respectively arranged below the main roller mounting base 1 and the main roller mounting base 2 of the utility model, which can realize the synchronous lifting and lowering adjustment of the main roller mounting base 1 and the main roller mounting base 2, and then drive the welded workpiece to adjust in the height direction, having good adaptability with the welding equipment. Two groups of auxiliary support structures are arranged between the main roller mounting base 1 and the main roller mounting base 2. The auxiliary support structures can be adjusted in the height direction and the horizontal direction, and the auxiliary support rollers 14 are used to assist in supporting the workpiece to ensure uniform force on the welded part, thereby improving the welding quality.
