Description

Technical Field

[0001] This utility model relates to the field of screw processing, and more specifically, to a thread rolling machine for screw processing. Background Technology

[0002] Screws are a commonly used tool for fixing objects in daily life and production. When processing screws, a thread rolling machine is required. Existing thread rolling machines for screw processing are fast and efficient, making them convenient for personnel to use when producing screws.

[0003] The utility model patent with authorization announcement number CN 216420953 U belongs to the field of screw processing, specifically a thread rolling machine for screw processing, including a thread rolling machine and a buffer mechanism; the buffer mechanism is located below the thread rolling machine; the buffer mechanism includes a buffer tube, a fixed tube, a telescopic tube, and a limiting spring; a buffer seat is provided at the bottom of the thread rolling machine; by setting the buffer mechanism, the thread rolling machine will generate a certain vibration during the screw processing process, thereby causing the thread rolling machine to move downward. When the thread rolling machine moves downward, it will press down the telescopic tube, causing the telescopic tube to move downward along the fixed tube, compressing the limiting spring between the bottom of the telescopic tube and the top of the fixed tube. Then, due to the elastic potential energy generated by the limiting spring, one end of it will push the telescopic block and the thread rolling machine upward, thereby achieving the purpose of buffering the vibration generated during the operation of the thread rolling machine, thus protecting the internal components of the thread rolling machine and improving its service life.

[0004] In the above-disclosed structure, a buffer structure is connected via a thread rolling machine and used in combination with a limiting structure. However, the limiting structure is distributed at the four corners and needs to be adjusted individually. It cannot be adjusted synchronously, resulting in poor adaptability. Furthermore, it lacks a conical positioning groove to connect the conical head, making it impossible to accurately insert and limit the position. This affects the convenience and stability of installation and needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a thread rolling machine for screw processing. The machine body is connected to the base, and the limiting plate and the tapered head are connected by tapered positioning holes on both sides, which can be inserted for positioning, which is conducive to centering and limiting, and is precise and stable. Furthermore, the cylinder mounting hole is used to install a tightening spring and a sliding rod, and the connecting hole is used to install a pull rope, which can tighten and separate to avoid interference. At the same time, it can be pulled and adjusted for synchronous control, which is precise, efficient, highly adaptable, and easy to install and use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0020] Please see Figure 1 , Figure 2 and Figure 3 A thread rolling machine for screw processing includes a base 1. The upper surface of the base 1 is provided with a connecting groove 11. The thread rolling machine body 12 is assembled and installed inside the connecting groove 11. The two ends of the thread rolling machine body 12 are provided with conical positioning grooves 13. The two ends of the base 1 are provided with mounting holes 14. A tightening spring 15 is slidably installed at one end of the mounting hole 14. A sliding rod 16 is fixedly connected to one end of the tightening spring 15. One end of the sliding rod 16 is slidably installed inside the mounting hole 14. A limit plate 17 is fixedly connected to the other end of the sliding rod 16. A conical head 18 is fixedly connected to one end of the limit plate 17. The conical head 18 is inserted into the conical positioning groove 13. An intermediate rod 19 is fixedly connected to the other end of the limit plate 17. The intermediate rod 19 is slidably connected to both ends of the base 1. A connecting hole 2 is provided at one end of the mounting hole 14. A pull rope 21 is slidably connected inside the connecting hole 2. One end of the pull rope 21 is fixedly connected to one end of the sliding rod 16.

[0021] Please see Figure 2 and Figure 5 One end of the connecting hole 2 is provided with an adjustment hole 22, which is located in the middle of the interior of the base 1. An adjustment rod 23 is rotatably installed inside the adjustment hole 22. Both ends of the adjustment rod 23 are provided with winding grooves 24, which are wound and connected to one end of the pull rope 21. One end of the adjustment rod 23 is fixedly connected to a polygonal positioning rod 25, which is rotatably installed on one side surface of the base 1. By installing the adjustment rod inside the adjustment hole and providing the winding grooves and polygonal positioning rod, the rope can be rotated and adjusted from the outside, thereby rotating and winding the pull rope from the inside. The rope facilitates unified pulling and adjustment, making it convenient, efficient, and easy to control. The polygonal positioning rod 25 can be manually adjusted, causing the internal adjusting rod 23 to rotate. The rope 21 on both sides can be wound around the winding groove 24, thereby pulling the sliding rod 16 to slide into the mounting hole 14, thus moving the limiting plate 17 and the conical head 18. It can be inserted into the conical positioning groove 13 for centering and limiting, ensuring precision and stability. This allows for auxiliary limiting of the tooth rolling machine body 12 from both ends, improving stability, facilitating installation and use, and providing convenience, stability, and high adaptability.

[0022] Please see Figure 1 , Figure 2 and Figure 4A fixing block 26 is fixedly connected to one side of the base 1. A locking screw 27 is rotatably installed inside the fixing block 26. One end of the locking screw 27 is rotatably connected to a limiting block 28. The limiting block 28 is tightly connected to one side surface of the polygonal positioning rod 25. A slot 29 is provided on one side of the limiting block 28. The slot 29 is engaged at the corner position of the polygonal positioning rod 25. The fixing block connects the locking screw and the limiting block. Combined with the slot on the surface, the locking block can be tightened and positioned by thread adjustment. It can be limited to the plane and corner positions, thereby improving the limiting stability, facilitating adjustment and use, and ensuring stability and efficiency. After manually rotating the polygonal positioning rod 25, the locking screw 27 can be rotated to push the limiting block 28, which can be tightened onto the plane of the polygonal positioning rod 25. This can assist in positioning and prevent rotation. Alternatively, the slot 29 can be engaged at the corner position of the polygonal positioning rod 25 for locking and positioning, which can also assist in positioning. This can increase the angle range of the limiting support, ensure the stability of the combined positioning, and facilitate adjustment and use.
