Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a device for cleaning or painting mounting holes of large-scale annular parts. Background Art

[0002] Large ring-type parts include wind power, construction machinery, tower cranes, vehicle-mounted mobile cranes, or slewing supports for rotation or rotation of large work platforms; flanges for large pipelines, reaction vessels, separation vessels and other equipment.

[0003] The characteristics of such parts are: large size, with a maximum outer diameter of 7-15 meters; huge weight, up to 20-30 tons; small batch size: mostly small batches or even single pieces; high value; high quality of machining, especially painting and corrosion protection.

[0004] Due to the large size and weight of such parts, lifting and turning them over are not only time-consuming, laborious and unsafe, but each lifting will also have an adverse effect on the processing quality, especially the painting quality.

[0005] Some manufacturers use automatic cleaning and brushing devices, generally in the following two ways:

[0006] 1. The workpiece rotates precisely, and the robot or mechanical arm automatically moves the spray hole up and down. The main problems are:

[0007] 1.1. The workpiece is heavy, and the support table and the drive slewing support have a huge moment of inertia, which leads to a high cost for the drive and support system and difficulty in maintaining transmission accuracy for a long time.

[0008] 1.2. When the specifications and models of the workpiece are changed, it is necessary to adjust the radial position size between the spray gun and the workpiece, which is a semi-automatic operation with large workload and long time consumption.

[0009] 1.3 Since the workpiece is heavy and bulky, when it is placed on the rotary worktable, the concentricity of the rotary center of the turntable and the workpiece is required to be high, which consumes a lot of clamping time.

[0010] 2. The workpiece is stationary, and the robot and visual inspection device are accurately rotated and positioned. The main problems are:

[0011] 2.1. The increase in the diameter of the workpiece requires the bracket of the robot and the visual inspection device to be enlarged accordingly. In addition, the corresponding workpiece must be rigid enough to avoid shaking during the rotation start and stop process.

[0012] 2.2. Also requires a high torque, high precision indexing device;

[0013] Both of the above methods require a visual system to accurately identify the position of the holes and adopt specific algorithms to ensure that the installation holes are not repeatedly cleaned or painted. The overall cost is high, and the adjustment time is long when changing workpieces, especially when changing varieties, and the operator's technology and skills are high.

[0014] Therefore, it is necessary to design a device for cleaning or painting the mounting holes of large ring-like parts. Utility Model Content

[0038] like Figure 1 Or a device for cleaning or brushing the mounting holes of large ring-like components as shown in 2, includes a device body 2, and the device body 2 is arranged on the annular plane of the large ring-like component 1.

[0039] The lower end of the device body 2 is provided with a plurality of universal wheels 4 in contact with the annular plane, and the universal wheels 4 are supporting universal wheels in four different directions, and the surface of the supporting universal wheels is a rubber buffer layer or a polyurethane buffer layer to avoid damage to the contact surface of the workpiece.

[0040] A universal wheel adjustment seat 41 is provided on the top of the universal wheel 4, and an adjustment rod 42 is provided on the top of the universal wheel 4. The adjustment rod 42 passes through the adjustment slot 411 of the universal wheel adjustment seat 41, and the position of the universal wheel 4 is radially adjusted by the adjustment rod 42. The four universal wheels 4 can adjust the spacing along the radial direction of the workpiece to meet the needs of different workpieces. After the positioning is coordinated, it can ensure that the center of the brush head structure 5 coincides with the center of the mounting hole 6.

[0041] A brush head seat 51 is arranged on the mounting platform of the device body 2, and a reciprocating brush head structure 5 is arranged on the brush head seat 51 through a linear guide module 7. The reciprocating motion of the brush head structure 5 is adjusted by a lifting motor 8. A rotating brush head (not shown in the figure) is arranged at the end of the brush head structure 5, and the rotation of the rotating brush head is achieved by driving a hollow turntable 10 on the brush head (not shown in the figure) by a rotating motor 9.

[0042] Since the spacing between the mounting holes 6 of different workpieces and the inner and outer arc surfaces is different, in order to ensure that the brush head structure 5 can be radially aligned with the center of the hole 6, the brush head seat 51 is driven by the slide 17 to move radially along the workpiece 1; the slide 17 is driven by the screw 16, and the movement of the screw 16 is adjusted by the hand wheel 15.

[0043] A plurality of radial positioning wheels are provided at the lower end of the device body 2 , and the radial positioning wheels move along the arc surface of the workpiece 1 .

[0044] The radial positioning wheels are an inner diameter positioning wheel set 111 arranged on the inner diameter of the arc-shaped surface of the workpiece 1 and an outer diameter positioning wheel set 112 arranged on the outer diameter of the arc-shaped surface of the workpiece 1 .

[0045] The outer diameter positioning wheel set 112 moves along the radial direction of the workpiece 1 through the outer diameter positioning wheel sliding mechanism 113 , and the movement of the outer diameter positioning wheel sliding mechanism 113 is controlled by the translation motor 13 and the translation reducer 14 .

[0046] The inner diameter positioning wheel set 111 includes a first positioning wheel and a second positioning wheel connected by the track 12 .

[0047] Because of the above structure, the working principle of the utility model is:

[0048] Place the device as a whole on the plane of the workpiece. If there is a height difference between the inner and outer rings of the workpiece 1, the height of the inner and outer ring universal wheels 4 needs to be adjusted to ensure that the table of the device is parallel to the workpiece and the brush head structure 5 is parallel to the center of the mounting hole 6 of the workpiece (to be processed);

[0049] By adjusting the horizontal position of the right outer diameter positioning wheel set 112, the inner or outer arc surface of the workpiece is closely fitted to the crawler 12;

[0050] Adjust the horizontal position of the slide 17, i.e. the cleaning brush device, so that it is concentric with the mounting hole 6, and then connect the pipeline of the spraying system to start operation.

[0051] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above.

[0052] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected.
