Description

Technical Field

[0001] This utility model relates to the field of powder forming mold frame technology, specifically a high-precision synchronous gear transmission device for powder forming mold frames. Background Technology

[0002] Powder forming mold frame, usually refers to the mold support and action execution system used for powder metallurgy forming or powder pharmaceutical tableting. It is the core component of powder compression molding machine and directly determines the product's precision, consistency and production efficiency. Synchronous gear transmission device is a mechanical component used in the transmission system of powder compression molding machine. Its wheel surface has regularly arranged teeth. These teeth mesh precisely with the tooth grooves on the back of the synchronous belt, which can achieve synchronous transmission without slippage.

[0003] Existing synchronous gear transmission devices have the following problems: The existing synchronous gear transmission device has a simple structure for connecting to the shaft. However, after long-term use, the mounting groove will wear down. This wear will cause the clearance between the shaft and the mounting groove to increase, leading to a series of problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision synchronous gear transmission device for powder forming mold frame, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision synchronous gear transmission device for powder forming mold frame, comprising a gear body, an installation groove provided in the gear body, a shaft provided in the installation groove, a connecting structure provided on the shaft, the connecting structure including a mounting platform, the mounting platform formed on the shaft, a threaded hole provided inside the shaft, a threaded opening provided on the gear body, a first positioning block provided on the shaft, and a second positioning block provided in the gear body.

[0006] Preferably, at least three threaded holes are provided and are evenly distributed on the shaft, and the number of threaded openings is the same as the number of threaded holes.

[0007] Preferably, when the shaft body is aligned with the mounting groove, the first positioning block will abut against the surface of the second positioning block.

[0008] Preferably, when the first positioning block abuts against the surface of the second positioning block, the threaded opening is aligned with the threaded hole.

[0009] Preferably, there are two first positioning blocks and two second positioning blocks, with a connection port formed between the two second positioning blocks. When the shaft body is connected to the mounting groove, the second positioning blocks move into the connection port.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Align the mounting slot with the shaft. During alignment, the second positioning block will move into the connection port. At this point, place the gear body against the mounting table surface. Then, thread the bolt through the threaded opening and thread the bolt into the threaded hole to fix the gear body onto the shaft. The gear body will press against the mounting table surface, effectively suppressing gear body skewing, providing an anti-skewing effect, improving stability, and offering high precision. When the shaft rotates, it will be driven by the first and second positioning blocks, resulting in high transmission efficiency. Over a long period of time, the bolt will not deform, preventing thread jamming during subsequent disassembly. Attached Figure Description

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0017] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a high-precision synchronous gear transmission device for powder forming mold frame, including a gear body 1, whose wheel surface is provided with regularly arranged teeth, which precisely mesh with the tooth grooves on the back of the synchronous belt, enabling synchronous transmission without slippage. The gear body 1 is provided with a mounting groove 2, which can be connected to a shaft 3, and a connecting structure 4 is provided on the shaft 3.

[0018] Please see Figure 3 and Figure 4 This utility model provides a high-precision synchronous gear transmission device for powder forming mold frame. The connecting structure 4 includes a mounting platform 41. The mounting platform 41 is formed on the shaft 3. Six threaded holes 42 are opened inside the shaft 3 and are evenly distributed on the shaft 3. The gear body 1 has the same number of threaded openings 43 as the threaded holes 42.

[0019] The shaft body 3 has a first positioning block 44 integrally formed on its surface, and there are two first positioning blocks 44. The gear body 1 has a second positioning block 45 integrally formed on its surface, and there are two second positioning blocks 45. A connection port 46 is formed between the two second positioning blocks 45. When the shaft body 3 is connected to the mounting groove 2, the second positioning block 45 moves into the connection port 46. When the shaft body 3 is connected to the mounting groove 2, the first positioning block 44 will abut against the surface of the second positioning block 45. When the first positioning block 44 abuts against the surface of the second positioning block 45, the threaded opening 43 will align with the threaded hole 42.

[0020] Specifically, during the installation of the gear body 1, the mounting groove 2 is aligned with the shaft 3. During alignment, the second positioning block 45 moves into the connection port 46. At this time, the surfaces of the first positioning block 44 and the second positioning block 45 are in contact. Then, the gear body 1 is placed against the surface of the mounting platform 41. When the second positioning block 45 moves into the connection port 46, the threaded opening 43 aligns with the threaded hole 42. After alignment, the bolt is threaded through the threaded opening 43 and threaded into the threaded hole 42, thereby fixing the gear body 1 onto the shaft 3. At this time, the gear body 1 presses against the surface of the mounting platform 41, effectively suppressing the gear body 1 from tilting, providing an anti-tilting effect, improving stability, and achieving high precision. Since the first positioning block 44 moves into the connection port 46 and the first positioning block 44 and the second positioning block 45 are in contact with each other, the shaft 3 rotates through the first positioning block 44 and the second positioning block 45, resulting in high transmission efficiency. Over a long period of time, the bolt will not deform, thus preventing the bolt from getting stuck during subsequent disassembly.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
