[0005] To address the aforementioned problems, this utility model provides a threaded hole processing device. By clamping the workpiece to be processed using two positioning plates, a combined workpiece is obtained. The combined workpiece is rotated to process holes on the outer circle of the workpiece corresponding to each side, thereby reducing manual alignment time and solving the problem of low processing efficiency of the fixed plate in the prior art.

[0006] To achieve the above objectives, this utility model provides a threaded hole processing device, comprising: a first positioning plate, the first positioning plate having a regular polygonal structure, the number of sides of the first positioning plate being determined according to the number of processing holes in the workpiece to be processed; at least one first fixing hole being provided on the first positioning plate; a second positioning plate, the shape and size of the second positioning plate being consistent with the first positioning plate; a second fixing hole being provided on the second positioning plate corresponding to the first fixing hole; and a fastener, wherein when the first positioning plate and the second positioning plate clamp the workpiece to be processed, the fastener sequentially passes through the first fixing hole, and the workpiece to be processed is connected to the second fixing hole.

[0007] Optionally, the first fixing hole is a through hole; the second fixing hole is a threaded hole; and the fastener is a screw.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Figure 1 This is a schematic diagram of the top structure of the fixed disk provided by existing technology. Figure 2 This is a side sectional view of a fixed disk provided by existing technology, with Figure 1 , Figure 2 Taking the fixed disc shown as an example, the process requires machining six M6 threaded holes on the outer surface of the fixed disc. The part is only 20mm thick and has a diameter of Φ320mm. During the fitter's operation, each thread needs to be aligned individually, resulting in low processing efficiency.

[0023] To address the problems of low efficiency and poor quality in existing thread hole processing technologies, this utility model provides a thread hole processing device, such as... Figure 3 , Figure 4 As shown, the device includes: a first positioning plate 1, which is a regular polygonal structure, and the number of sides of the first positioning plate 1 is determined according to the number of machining 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, which has the same shape and size as 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; and a fastener, which passes through the first fixing hole 101 and the workpiece 3 to be processed sequentially when the first positioning plate 1 and the second positioning plate 2 clamp the workpiece 3 to be processed.

[0024] Figure 3 This is a schematic diagram of the structure of the first positioning plate 1 of the thread processing device provided in this embodiment of the utility model, as shown below. Figure 3 As shown, the first positioning plate 1 is a regular polygonal structure, and the number of its sides is determined by the number of holes 302 required to be machined in the workpiece 3 to be processed.

[0025] If it is necessary to achieve Figure 1 If six machining holes 302 are to be machined, the first positioning plate 1 needs to be designed as a regular hexagonal structure. Of course, for the need to machine two machining holes 302 and three machining holes 302, a regular hexagonal structure can be used to realize the thread machining requirements. Alternatively, for the need to machine three machining holes 302, a regular triangular structure can be designed.

[0026] At least one first fixing hole 101 is formed on the surface of the first positioning plate 1, and the position of the first fixing hole 101 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 at least one second fixing hole 201 is provided on it. The first fixing hole 101 and the second fixing hole 201 are provided in correspondence, and their number and position are also corresponding.

[0028] In use, the positioning components pass through the first fixing holes 101 of the first positioning plate 1 and the holes of the workpiece 3 one by one, and then connect with the second fixing holes 201 of the second positioning plate 2 to form a whole. During processing, one of them can be placed on a plane, and its opposite side limits a drilling range. At this time, a machining tool can be used to drill holes in the fixed plate within the drilling range. By rotating multiple sides in sequence, all holes are processed.

[0029] As an optional implementation, 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 with a size of Φ5. The second fixing hole 201 is a threaded hole, preferably with a thread size of M6. The fastener is a screw, which passes through the first fixing hole 101, the existing hole 301 of the workpiece 3 to be processed, and the second fixing hole 201 in sequence for threaded connection.

[0031] As an optional implementation, both the first positioning plate 1 and the second positioning plate 2 are regular hexagonal structures.

[0032] Preferably, both the first positioning plate 1 and the second positioning plate 2 adopt a regular hexagonal structure, which can adapt to the requirements of machining a variety of numbers of holes.

[0033] As an optional implementation, the surface of the first positioning plate 1 is provided with a soft material; the surface of the second positioning plate 2 is provided with a soft material.

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

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

[0036] The surface of the soft material has anti-slip textures, which can increase friction to further improve the stability of the mounting.

[0037] As an optional implementation, the first positioning plate 1 has four first fixing holes 101; the second positioning plate 2 has four second fixing holes 201.

[0038] like Figure 2 As shown, the first positioning plate 1 has four first fixing holes 101, which are located at the four corners of a rectangle. The second positioning plate 2 has four second fixing holes 201 at positions corresponding to the first fixing holes 101.

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

[0040] Furthermore, to improve ease of installation, locating pins are provided on both positioning plates. During installation, the locating pin on one positioning plate is first passed through the through hole of the workpiece 3 to be processed, and the locating pin on the other positioning plate is passed through the through hole of the workpiece 3 from the other side, so that the three components can be quickly positioned. The position of the locating pins is set according to the requirement that the fixing holes can be aligned.

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

[0042] To facilitate workpiece processing, this embodiment features graduations along the edges of the first positioning plate 1 and the second positioning plate 2, with a separate column of graduations for each edge, ensuring accurate drilling. If a dedicated tooling is used, markings can be made at the corresponding drilling positions on each edge, ensuring drilling is performed according to these markings.

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

[0044] The first positioning plate 1 has a side dimension of 330mm and a thickness of 6mm, and is manufactured by slow wire cutting.

[0045] The second positioning plate 2 has a side dimension of 330mm and a thickness of 6mm, and is manufactured by slow wire cutting.

[0046] The above technical solution has the following beneficial effects: by clamping the workpiece 3 to be processed by the first positioning plate 1 and the second positioning plate 2, the positioning convenience of the workpiece is improved; by using the regular polygonal structure of the first positioning plate 1 and the second positioning plate 2, each processing hole 302 corresponds to a side of a regular polygon, and by rotating the polygon, each hole corresponding to each side can be processed, saving scribing time and improving the accuracy of the processing position.

[0047] The above-described specific embodiments of the utility model further illustrate the purpose, technical solution, and beneficial effects of the utility model. It should be understood that the above content is only a specific embodiment of the utility model and is not intended to limit the scope of protection of the utility model.
