Embodiment Construction
[0046] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.
[0047] The invention provides a tool for drilling a cylindrical structure, and is especially suitable for drilling the outer periphery of a large cylindrical structure. As a typical application, the tooling can be used to complete the drilling of bolt holes at the center tube of the riser guide and fixture of the floating oil storage platform and the connection part of the upper bell mouth.
[0048] refer to Figure 1 to Figure 5 The tooling of this embodiment mainly includes a stage 1, a fixing mechanism 2 connected to one side of the stage 1, an adjust...

The invention discloses a tooling and processing method for drilling a cylindric structure. The tooling comprises a carrier platform, a fixed mechanism, a regulating mechanism, a locating mechanism, and a mounting base. The fixed mechanism comprises an internal fixation piece and an external locking piece; the internal fixation piece with the cylindrical peripheral surface is able to aptly stick into the cylindric structure; the external locking piece is able to be adjacent to the outside wall of the cylindric structure, so that the carrier platform and the cylindric structure are fixedlyconnected; the regulating mechanism includes an adjusting plate and an adjusting seat that are able to rotate relatively; a plurality of adjusting holes are arranged on the adjusting plate, the adjusting holes corresponds to the circular distribution of holes to be machined in the cylindrical structure; the locating mechanism is fixedly connected with the adjusting seat; the locating mechanism isprovided with a locating piece, the locating piece is able to be connected and cooperate with different adjusting holes as the adjusting seat rotates to fix the locating of the adjusting seat and theadjusting plate; the mounting base is used for mounting a drilling equipment; and the mounting base is connected with the adjusting seat in a fixed form. According to the tooling and processing methodfor drilling the cylindric structure, a vertical pipe guide fixing device of floating oil storage platform is able to be drilled and machined.
Description
technical field [0001] The invention relates to the technical field of tooling equipment, in particular to a tooling and a processing method for drilling holes in cylindrical structures, especially for drilling operations in large cylindrical structures, such as for the riser of a floating oil storage platform The central cylinder of the guiding fixture and the drilling of the upper bell mouth. Background technique [0002] The riser guiding and fixing device (Bell Mouth) of the floating oil storage platform includes a central cylinder and an upper bell mouth sleeved on the upper end of the central cylinder. The central cylinder is a straight cylindrical structure, and the upper bell mouth is a trumpet-shaped structure with a larger opening at the upper end and a smaller opening at the lower end. Before the two are connected, several holes need to be drilled along the circumferential direction of the two, and then the two are connected and fixed by bolts passing through the...
