[0001] The utility model relates to the technical field of crane structural part flange machining, in particular to a large-diameter flange end face machining device with a variable radius. Background Art

[0002] With the continuous development of the crane industry, the overall size of the structural parts is increasing, and the diameter of the flange used for the slewing support is also increasing. Conventional end face machining equipment can no longer support the end face machining of large diameter flanges. The machining radius of the existing end face machining equipment is 2 to 3 meters, while for structures such as offshore cranes or full-slewing floating cranes, it is necessary to machine the end face of the slewing support flange, and the diameter of the slewing support flange end face is more than 15 meters; therefore, the existing end face machining equipment cannot meet the machining needs of offshore cranes or full-slewing floating crane structures.

[0003] In order to achieve the above-mentioned large-diameter flange end surface processing, on the one hand, the existing end surface machining equipment is used, but the position of the equipment base needs to be constantly adjusted during the processing, which is inconvenient and easy to cause processing errors. On the other hand, the crane structure is transported to the machine tool factory for processing, but due to the influence of the structure size, transportation is inconvenient and the labor cost is high. Utility Model Content

[0010] As a further implementation, the cross-sectional shape of the extended forearm is the same as the cross-sectional shape of the main slewing and adjusting arm.

[0011] As a further implementation, the extended forearm is surrounded by side panels and has openings at both ends.

DETAILED DESCRIPTION

[0030] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0031] Embodiment 1

[0032] In a typical implementation of the present invention, reference is made to Figure 1-Figure 5 As shown, a large-diameter flange end surface processing device with a variable radius includes a base 1 as a support, the top of the base 1 is rotatably connected to the main slewing 2, a counterweight 4 is provided at one end of the main slewing 2, and the other end is used to connect with an adjusting arm 5, a lateral adjustment component is provided on the adjusting arm 5, a vertical adjustment component 8 is provided on the lateral adjustment component, and a tool 84 is connected to the bottom end of the vertical adjustment component 8. By adjusting the lateral adjustment component and the vertical adjustment component 8, the position of the tool 84 is adjusted, and then the crane structure is processed.

[0033] like Figure 1 and Figure 2As shown, the base 1 is arranged on the ground, and the base 1 is rotationally connected with the main slewing 2 through a slewing support, and drives the main slewing 2 to rotate through a slewing driving member 3. The slewing driving member 3 is arranged on the top side of the base 1, and its output end cooperates with the slewing support to realize the rotation of the slewing support, thereby driving the main slewing 2 to rotate.

[0034] As shown in Figure 1, the end of the adjustment arm 5 is fixedly connected to the end of the main slewing 2 away from the counterweight 4 through the end plate 91 and the bolt group, and is detachable. When the adjustment arm 5 is connected to the main slewing 2, the main slewing 2 drives the adjustment arm 5 to rotate, and then the tool is adjusted through the lateral adjustment component and the vertical adjustment component, so as to process the structure.

[0035] It can be understood that when the adjustment arm 5 is directly connected to the main swing 2, the purpose is to achieve a small moment of inertia solution when a conventional small-diameter workpiece is frequently processed, for energy saving.

[0036] A transverse track is provided on one side of the adjusting arm 5 along the length direction, and a horizontal screw 6 is provided on the transverse track. The horizontal screw 6 is connected to the first motor and cooperates with the slide. The first motor 7 is provided at the front end of the adjusting arm 5. The first motor 7 drives the horizontal screw 6 to rotate, so that the slide 10 moves along the transverse track, thereby driving the vertical adjustment component 8 to move.

[0037] The slide 10 is provided with a rotatable vertical lead screw 82, the top of which is connected to a second motor 81, which cooperates with a nut seat 83, and the bottom of the nut seat is connected to a tool 84. The second motor is provided at the top of the slide 10, and the second motor 81 drives the vertical lead screw 82 to rotate, thereby realizing the up and down movement of the nut seat 83, thereby driving the tool 84 to adjust the up and down position.

[0038] When a small amount of processing is performed on large-diameter workpieces, the processing radius of existing end face machining equipment is 2 to 3 meters, and the processing diameter is 4 to 6 meters. However, for structures such as offshore cranes or full-rotation floating cranes, the end face of the slewing support flange needs to be processed. The diameter of the slewing support flange end face is more than 15 meters, and the processing radius of the equipment needs to be at least 8 meters. The existing end face machining equipment cannot meet the processing needs. Although it is feasible to re-produce large-diameter end face machining equipment, it requires enterprises to purchase it again, which is too costly. In addition, large-diameter end face machining equipment is obviously not suitable for frequent processing of conventional small-diameter workpieces. If the structure is transported to a machine tool factory for processing, the transportation cost and labor cost will increase.

[0039] Based on the above considerations, this embodiment improves the existing end surface machining equipment, such as Figure 1As shown, the original main slewing 2 and the adjusting arm 5 are an integral cantilever structure. The cantilever mechanism is separated to obtain the main slewing 2 and the adjusting arm 5, and an end plate 91 is set at the cutting position. At least one circle of threaded holes is set in the circumferential direction on the end plate, so that the main slewing 2 and the adjusting arm 5 can be detachably connected through the end plate and the bolt group.

[0040] In order to extend the processing radius of the equipment, this embodiment provides a plurality of extended forearms 9, such as Figure 3 As shown, different lengthened forearms 9 have different lengths and can be adapted to working conditions with different machining radii.

[0041] The cross-sectional shape of the extended front arm 9 is the same as that of the main swing arm 2 and the adjustment arm 5. Figure 4 and Figure 5 As shown, the extended forearm is welded by four side plates 93, with openings at both ends. End plates 91 are correspondingly provided around the openings at both ends. The end plates 91 are annular structures, and bolt holes are also correspondingly provided on the end plates 91, so that the end plates of the extended forearm can be spliced ​​between the main slewing arm 2 and the adjusting arm 5 through the bolt group 92 to change the processing radius.

[0042] When working with large diameters and small amounts of processing, select an extended forearm of appropriate length according to the radius of the crane structure to be processed, and splice it between the main slewing and adjusting arms through the end plate and bolt group, thereby changing the processing radius of the equipment and realizing the processing of the end face of the large-diameter slewing support flange, such as Figure 3 shown.

[0043] The extended forearm 9 is tilted relative to the horizontal direction, and the side plate 93 is thickened to improve the rigidity. After the extended forearm is installed, the corresponding counterweight should be increased in weight. The length of the extended forearm 9 can be 2 meters, 4 meters, or 6 meters, and can be made according to the needs of the enterprise, and the extended forearm 9 can be assembled and installed between the main slewing arm 2 and the adjusting arm 5. The improved equipment can meet the maximum 15-18m diameter flange end surface processing work, with low cost, energy saving, easy assembly, and reliable processing quality.

[0044] When machining the end face of a large-diameter slewing support flange, place the installed equipment at the center of the structure. After adjusting the machining radius, the main slewing 2 drives the adjusting arm and the tool to perform machining through the extended forearm 9.

[0045] The setting of the extended forearm 9 in this embodiment enables the existing end face machining equipment, after being combined with the extended forearm 9, to not only adopt a small moment of inertia solution for energy saving when conventional small-diameter workpieces are frequently processed (the main swing 2 is directly connected to the adjustment arm), but also to achieve large-diameter structure processing by splicing the extended forearm 9 when large-diameter workpieces are processed in small quantities. Therefore, there is no need to purchase new processing equipment, and the improved equipment has a wider processing range and can meet the processing needs of structures of various sizes.

[0046] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
