Problems solved by technology
The other ends of the two legs have mounting flanges. When making the bolt cylinder support, the positional relationship between the mounting flanges on the two legs and the two ear plates has high precision requirements. If the deviation is too large, After the bolt cylinder bracket is installed on the upper ring beam or the lower ring beam, the installation accuracy of the bolt cylinder will not meet the requirements

Embodiment Construction
[0044] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0045] figure 1 It is a structural schematic diagram of a bolt cylinder support provided by an embodiment of the present invention. Such as figure 1 As shown, the bolt cylinder support includes a mounting beam 11 , two ear plates 12 and two legs 13 . The mounting beam 11 has a rectangular surface 11a on which the two lugs 12 and the two support legs 13 are connected. Two ear plates 12 are located between two legs 13 , one end of each leg 13 is connected to the mounting beam 11 , and the other end of each leg 13 is connected to a mounting flange 14 . The two mounting flanges 14 and the two lugs 12 are symmetrical about the same line m perpendicular to the rectangular surface 11a.
[0046] A mounting plate 121 is also arranged on the...

Abstract
The invention discloses a machining tool and a machining method of a bolt oil cylinder bracket, and relates to the field of machining. The tool comprises a lead hammer, a mounting frame and two support legs; the two support legs are connected with the mounting frame; the lead hammer is connected to the mounting frame through a flexible rope; the mounting frame is provided with two bracket clampinggrooves at intervals; the two bracket clamping grooves are in central symmetry about the connecting point between the flexible rope and the mounting frame; the bracket clamping grooves are as wide asmounting flanges of the bolt oil cylinder bracket; the smallest distance between the two bracket clamping grooves is the same with the smallest gap between the two mounting flanges of the bolt oil cylinder bracket; and as the two bracket clamping grooves are in central symmetry about the connecting point between the flexible rope and the mounting frame, during machining, orthographic projectionsof the symmetric centers of the two bracket clamping grooves and the symmetric centers of two lug plates on the same horizontal plane can be overlapped through the lead hammer, the position relation between the mounting flanges on the two support legs and the two lug plates meets the design requirements, and the manufacturing precision of the bolt oil cylinder bracket is improved.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing tool and a processing method for a bolt cylinder support. Background technique [0002] The offshore platform is a very widely used offshore drilling equipment. It mainly includes the main body of the platform, legs, and a lifting system. The lifting system is used to realize the lifting of the main body of the platform. [0003] The existing lifting system of the offshore platform is usually a bolt lifting system, and the bolt lifting system mainly includes an upper ring beam, a lower ring beam, a lifting cylinder, a bolt and a bolt cylinder. The upper and lower ring beams surround the pile legs, the lower ring beam is fixedly connected to the main body of the platform, and the upper ring beam and the lower ring beam are connected by lifting cylinders. Both the upper ring beam and the lower ring beam are equipped with multiple bolts and bolt cylinders. The pins...
