Embodiment Construction
[0024] Such as Figure 1 to Figure 11 As shown, the present invention includes a base 1, a fixing ring 2 and a drilling plate 3, and the present invention will be described below in conjunction with the accompanying drawings.
[0025] Such as Figure 5 , Figure 6 As shown, the base 1 is a ring-shaped metal piece as a whole, including a first ring body 12 and a second ring body 11, the second ring body is a ring-shaped metal piece, and the outer wall of the second ring body is smooth. Both sides of the two rings are respectively fixed with a first ring 12, the first ring is also a circular metal piece, the inner diameter of the first ring is the same as the inner diameter of the second ring, and the outer diameter of the second ring is the same as that of the second ring. smaller than the outer diameter of the first annular body, and an external thread is provided on the outer wall of the second annular body.
[0026] Such as Figure 7 to Figure 9 As shown, the fixed ring ...

The invention discloses a drilling jig used for drilling a winding drum and relates to the technical field of drilling jigs for castings. The drilling jig is used for solving the problem that when an existing line marking manner is used for drilling a flange in the winding drum, the drilling precision does not reach the standard. The drilling efficiency and the universality of the drilling jig are improved. According to the drilling jig, a fixing ring can be added to a base so as to be fixed in the flange according to the inner diameter of the flange. A drilling plate is installed on the base, and a plurality of round holes are formed in the drilling plate. In the drilling process, a drill bit is aligned with a drill hole so that drilling can be conducted on the flange, the drilling precision is high, and efficiency is high. Meanwhile, drilling plates of different sizes can be installed on the base according to the different sizes of flanges so that the drilling requirement can be met, and drilling jigs of different sizes do not need to be manufactured independently. The drilling jig is applicable to flanges of different sizes, universality is high, and drilling jigs of different sizes do not need to be manufactured. Due to the fact that the winding drum is not in batch production, the problem of high cost when a machining center is used for drilling is solved.
Description
technical field [0001] The invention relates to the technical field of drilling molds for castings, in particular to a drilling mold used for drilling rolls. Background technique [0002] The reel can be used to wind the steel wire. The reel is obtained by casting. Generally, a flange should be installed in the inner cavity of the reel, and the flange and the reel are integrally cast for installation with other components. When drilling holes on the flange, it is generally to draw a line on the flange to determine the position of the threaded hole, and then drill through the drilling machine. In this way, it is difficult to ensure the accuracy of drilling to meet the requirements, and it is time-consuming and labor-intensive. The rolls are not mass-produced, and if a machining center is used to drill them, the production cost will be greatly increased and resources will be wasted. Contents of the invention [0003] The object of the present invention is to provide a dril...
