[0002] Currently, machining holes on slender workpieces with a length greater than 4 meters for deep-sea connectors generally requires machining on large gantry milling machines. Due to the length of the workpiece, if manual scribing is used to ensure the dimensions, the position of the holes will be offset due to the limitations of scribing equipment and the errors of manual measurement, and the machining dimensions cannot be guaranteed.

[0003] If CNC drilling machines are used directly for processing, the products are too long and the drilling machine platform is too small to be processed in one go. After each set of holes is processed, the products must be hoisted and moved again, and then re-clamped and aligned to process the next set of holes, which is inefficient.

[0004] This solution targets a slender workpiece with a shape similar to an arched plate. A rectangular plate is fixedly connected to one end of the arched plate along the length of the slender workpiece. A horizontal plate is located in the middle of the top of the arched plate, and outward-facing inclined plates are set on both sides of the arched plate. Several foot plates are set at both ends of the arched plate along the length of the slender workpiece.

[0042] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0043] like Figures 1 to 10 As shown, a drilling jig for a deep-sea slender workpiece is set on a slender workpiece 1. A rectangular plate 2 is fixed to one end of the slender workpiece 1. Two positioning pin holes are pre-machined on the rectangular plate 2. Other structural features of the slender workpiece 1 have been described in the background art and will not be detailed here.

[0044] The present invention includes a slender template 3. One end of the slender template 3 is provided with a pin hole 33 that is aligned with the position of the positioning pin hole. The slender template 3 is connected to the rectangular plate 2 of the slender workpiece 1 by the positioning pin and then fastened by connecting bolts.

[0045] Specifically, the positioning pin is inserted into the pin hole 33 and the positioning pin hole to connect the drilling jig tooling with the slender workpiece 1. Finally, the positioning accuracy of the hole to be processed is ensured by using the relevant structure on the rectangular plate 2 as the positioning reference.

[0046] The slender template 3 has several distribution holes 7, the positions of which correspond to the positions of the holes to be machined on the slender workpiece 1. Drill sleeves 6 are installed in the distribution holes 7. During machining, the slender template 3 is first fixed in place, and then the drill is placed into the distribution holes 7.

[0047] The preferred fit between the distribution hole 7 and the drill sleeve 6 is H7 / n6 to ensure machining accuracy. The drill sleeve 6 is preferably made of carbon tool steel with high strength and wear resistance to prevent the drill bit from damaging the drill sleeve 6 during machining. Furthermore, the upper outer wall of the drill sleeve 6 is preferably provided with a boss, which can be supported on the upper end face of the distribution hole 7 to facilitate the installation and removal of the drill sleeve 6.

[0048] Before actual processing, the center line needs to be drawn on the elongated workpiece 1 in advance, and the center line is also engraved on the elongated template 3 when the elongated template 3 is manufactured. During processing, the elongated template 3 is first positioned with the elongated workpiece 1 through the positioning pins, so that the center line of the elongated template 3 coincides with the center line of the elongated workpiece 1. Then, the elongated template 3 and the elongated workpiece 1 are fixed by using multiple industrial G-type clamps to prevent the elongated template 3 from moving during processing. At this time, the relative positions of the distribution holes 7 on the elongated template 3 are consistent with the positions of the holes to be processed on the elongated workpiece 1. In this way, after the elongated template 3 is fixed, it can be directly processed.

[0049] The other end of the elongated template 3, or both ends of the elongated template 3, is connected with an adjusting plate 31. The adjusting plate 31 can be fixed on the elongated template 3 by screws, or the two can be directly welded together. The adjusting plate 31 is provided with a threaded hole at the end away from the elongated template 3. An adjusting screw 32 is screwed into the threaded hole.

[0050] Specifically, the adjusting plate 31 is provided with an angled elbow plate. The angle of the elbow plate is consistent with the angle between the horizontal plate and the inclined plate on the elongated workpiece 1, so that the adjusting screw 32 can abut against the inclined plates on both sides of the elongated workpiece 1 perpendicularly.

[0051] Because the workbench of the drilling machine is small, part of the elongated workpiece 1 will extend outside the workbench during drilling. Therefore, the utility model also comprises at least one support frame 9. The support frame 9 can support the elongated workpiece 1 at the bottom along the length direction of the elongated workpiece 1. Generally, one support frame 9 can be provided every 3-5 meters. Specifically, the length of the support frame 9 can be selected according to the length of the elongated workpiece 1 to ensure that the elongated workpiece 1 remains horizontal and prevents bending due to its own weight. The height of the support frame 9 is preferably adjustable to meet the processing support needs of products of different specifications. The support frame 9 is preferably movable, and a roller can be arranged at the bottom of the support frame 9 to achieve movement.

[0052] Because the position of the hole to be processed on the elongated workpiece 1 is accurately positioned by the distribution hole 7 on the tooling, there is no need to worry about the impact of the movement of the elongated workpiece 1 on the processing positioning. The position of the elongated workpiece 1 can be adjusted by the movable support frame 9, which is simple and convenient, and does not require the use of a travelling crane or a crane resource.

[0053] The utility model discloses at least one elongated template 3. Adjacent elongated templates 3 are connected through two positioning pins and then fastened with bolts. This can avoid the manufacturing difficulties caused by the elongated template 3 being too long. When the elongated workpiece 1 is short, one elongated template 3 can be used. When the elongated workpiece 1 is long, multiple elongated templates 3 can be used. Moreover, multiple elongated templates 3 can meet the regular processing needs of elongated workpieces 1 of different lengths through splicing.

[0054] The utility model discloses an elongated template 3 both sides integrally connected with the inclined template 4, two inclined templates 4 all are inclined to the outside, when the elongated template 3 is set on the elongated workpiece 1, the inclined template 4 is parallel with the inclined plate of bottom, be equipped with a plurality of distribution holes 7 on the inclined template 4, the distribution hole 7 on the inclined template 4 corresponds the hole to be processed on the inclined plate, to avoid the deformation between the inclined template 4 and the elongated template 3, the upper portion of both preferably sets certain reinforcing rib 8 and strengthens.

[0055] The utility model discloses an elongated template 3 between the elongated workpiece 1 preferably pad is equipped with pad piece 10, pad piece 10 preferably connects in the elongated template 3 bottom, pad piece 10 can select bolt, bolt is screwed in the elongated template 3 bottom, when needing to adjust pad piece 10 height, only need to rotate bolt, the specific position and quantity of bolt need to guarantee that the elongated template 3 is placed stably on the elongated workpiece 1.

[0056] The utility model discloses another structure, the both ends of two inclined templates 4 are integrally connected with the footing template 5, the footing template 5 all extend horizontally to the outside, when the elongated template 3 is set on the elongated workpiece 1, the footing template 5 is horizontally located above the footing plate of elongated workpiece 1, and the distribution hole 7 is equipped on the footing template 5, and the distribution hole 7 on the footing template 5 corresponds the hole to be processed on the footing plate.
