[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Figure 1 is a schematic top view of the top surface of the fixed disk provided by the prior art. Figure 2 is a side cross-sectional view of the fixed disk provided by the prior art. Taking the fixed disk shown in Figure 1 、 Figure 2 as an example of the workpiece to be processed, the process requires that 6 M6 threaded holes be machined on the outer circular surface of the fixed disk. The thickness of this part is only 20 mm and the diameter is Φ320 mm. When the fitter processes the threads, each one needs to be aligned, resulting in low processing efficiency.

[0023] To solve the problems of low processing efficiency and poor quality of threaded holes in the prior art, an embodiment of the present invention provides a threaded hole processing device. As shown in Figure 3 、 Figure 4 , the device includes: a first positioning plate 1, the first positioning plate 1 is a regular polygon structure, and the number of sides of the first positioning plate 1 is determined according to the number of processing holes 302 of the workpiece 3 to be processed; at least one first fixing hole 101 is provided on the first positioning plate 1; a second positioning plate 2, the shape and size of the second positioning plate 2 are the same as those of the first positioning plate 1; a second fixing hole 201 corresponding to the first fixing hole 101 is provided on the second positioning plate 2; a fastener, when the first positioning plate 1 and the second positioning plate 2 clamp the workpiece 3 to be processed, the fastener sequentially passes through the first fixing hole 101, the workpiece 3 to be processed and the second fixing hole 201 for connection.

[0024] Figure 3 is a schematic structural view of the first positioning plate 1 of the thread processing device provided by an embodiment of the present invention. As shown in Figure 3 , the first positioning plate 1 is a regular polygon structure, and the number of its sides is determined according to the number of processing holes 302 required by the workpiece 3 to be processed.

[0025] If it is necessary to machine the six processing holes 302 in Figure 1 , the first positioning plate 1 needs to be designed as a regular hexagon structure. Of course, for the needs of machining two processing holes 302 and three processing holes 302, a regular hexagon structure can be used to meet the thread processing requirements, or for the need of three processing holes 302, a regular triangle structure can be designed.

[0026] At least one first fixing hole 101 is provided on the surface of the first positioning plate 1, and the position where the first fixing hole 101 is provided corresponds to the position of the existing hole 301 on the workpiece 3 to be processed.

[0027] The second positioning plate 2 has the same shape and size as the first positioning plate 1, and is provided with at least one second fixing hole 201. The first fixing hole 101 and the second fixing hole 201 are correspondingly arranged, and their numbers and positions correspond to each other.

[0028] During use, the positioning members are successively passed through the first fixing holes 101 of the first positioning plate 1 and the holes of the workpiece 3 to be processed, and then connected to the second fixing holes 201 of the second positioning plate 2, so as to form a whole. When processing, one of them can be placed on a plane, and its opposite side limits a drilling range. At this time, a processing tool can be used to drill the fixing plate within the drilling range. Rotate multiple sides in sequence to complete the processing of all holes.

[0029] As an alternative embodiment, the first fixing hole 101 is a through hole; the second fixing hole 201 is a threaded hole; and the fastener is a screw.

[0030] The first fixing hole 101 is a through hole. Preferably, its size is Φ5. The second fixing hole 201 is a threaded hole. Preferably, the size of the threaded hole is M6. The fastener is a screw, and the screw successively passes through the first fixing hole 101, the existing hole 301 of the workpiece 3 to be processed, and is threadedly connected to the second fixing hole 201.

[0031] As an alternative embodiment, both the first positioning plate 1 and the second positioning plate 2 are regular hexagon structures.

[0032] Preferably, both the first positioning plate 1 and the second positioning plate 2 adopt regular hexagon structures, which can meet the processing requirements of various numbers of holes.

[0034] To avoid abrasion of the workpiece 3 to be processed, soft materials are provided on the surfaces of the first positioning plate 1 and the second positioning plate 2. To reduce the tooling material consumption and weight, the soft material can be provided only on the side of the first positioning plate 1 that contacts the workpiece 3 to be processed. Similarly, the soft material is provided only on the side of the second positioning plate 2 that contacts the workpiece 3 to be processed.

[0035] As an alternative embodiment, the surface of the soft material is provided with anti-slip patterns.

[0037] As an alternative embodiment, four first fixing holes 101 are provided on the first positioning plate 1; four second fixing holes 201 are provided on the second positioning plate 2.

[0038] As shown Figure 2 in FIG. 1, four first fixing holes 101 are formed on the first positioning plate 1, and the four first fixing holes 101 are respectively located at the four corners of a rectangle. Four second fixing holes 201 are formed at positions corresponding to the positions of the first fixing holes 101 on the second positioning plate 2.

[0039] The four first fixing holes 101 on the first positioning plate 1 correspond to the four second fixing holes 201 on the second positioning plate 2 one by one, so that the fasteners can pass through without obstruction.

[0040] Furthermore, to improve the convenience of installation, positioning pins are provided on both positioning plates. During installation, first pass the positioning pin of one of the positioning plates through the through hole of the workpiece 3 to be processed, and pass the positioning pin of the other positioning plate through the through hole of the workpiece 3 from the other side of the workpiece 3 to be processed, so as to complete the quick positioning of the three components. Among them, the position of the positioning pin is set according to the requirement that the fixing holes can be aligned.

[0041] As an alternative embodiment, a scale is provided on the edge of the first positioning plate 1; the edge of the second positioning plate 2 has the same scale as the first positioning plate 1.

[0042] To make the workpiece processing more convenient, in this embodiment, scales are provided on the edges of the first positioning plate 1 and the second positioning plate 2, and a column of scales is separately set for each side, which can ensure drilling at an accurate position. If it is a special tooling, marks can be drawn at the positions corresponding to the holes on each side, so as to ensure drilling according to the marks.

[0043] As an alternative embodiment, the thickness of the first positioning plate 1 and the second positioning plate 2 is 6 mm.

[0044] The opposite side dimensions of the first positioning plate 1 are 330 mm, and the thickness dimension is 6 mm, which is processed by slow wire electrical discharge machining.

[0045] The opposite side dimensions of the second positioning plate 2 are 330 mm, and the thickness dimension is 6 mm, which is processed by slow wire electrical discharge machining.
