Description

Technical Field

[0001] The invention relates to the technical field of thread rolling machines, in particular to a thread rolling machine for screw processing. Background Art

[0002] A thread rolling machine is a tool or device used to create or repair threads in a threaded hole. It is also called a thread repair tool or thread repair machine. A thread rolling machine is often used to repair or restore damaged or worn threaded holes so that bolts, screws, or other threaded connections can be properly installed. It can repair threads of different types and sizes, including internal and external threads. A thread rolling machine usually consists of a rotating tool and a fixture with a corresponding thread blade. As the tool rotates, the fixture guides the blade into the threaded hole and cuts the material along the thread path to restore or create the thread. A thread rolling machine usually has an adjustable fixture and tool to accommodate different sizes and types of threads. Screw thread rolling machines are widely used in machinery manufacturing, automotive repair, aerospace, electronic equipment, and other fields that require threaded connections. They can help repair damaged threaded holes, avoid replacing the entire part or assembly, and save cost and time. The correct use of a thread rolling machine requires experience and skills to ensure the accuracy and quality of the thread.

[0003] However, the existing thread rolling machine has the following problems in the process of thread rolling the screws: the thread rolling is mainly achieved by the two sets of thread rolling plates installed on the thread rolling machine acting at high speed to reciprocate the column of the screw, and the thread rolling stripes on the surface of the thread rolling plate will be consumed by friction during the long-term thread rolling process, which requires manual inspection and replacement of the machine means. The part of the thread rolling plate that is actually used for the thread rolling operation belongs to a small local position of the thread rolling plate, which leads to the problem of insufficient utilization of the thread rolling plate and increases the replacement cost of the thread rolling plate. In addition, the guide rail used to guide the screw rod body is blocked during the material guiding process, which requires manual adjustment and cumbersome operation. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Summary of the invention

The rubbing plate 2 8 has the same structure as the rubbing plate 1 7. This design method is convenient for adjusting the rubbing position of the rubbing plate body 22, so that the other position of the rubbing plate body 22 is moved to the rubbing position. When the position of the rubbing plate body 22 is adjusted, the staff can energize the electromagnetic block 28. The electromagnetic block 28 is energized to generate magnetism and push the magnet 29 and the positioning rod 32 to move inward and insert them into the positioning hole 23, so as to achieve the purpose of limiting the rubbing plate body 22.

[0026] Further improvement, such as Figure 3 As shown: the regulator 9 includes a motor 24 installed on the top of the L-shaped top plate 21 and a screw 25 fixed to the power output end of the motor 24.

The expansion balls 37 are connected to the air cushion body 36. The expansion balls 37 are in contact with the outer side of the inner cushion 18. The expansion balls 37 expand when the inflatable cushion 17 is inflated. The expansion balls 37 act on the inner cushion 18 to adjust the screws of the inner lower guide to avoid blockage.

[0031] When in use: When the screw needs to be threaded, the worker can place the screw in the floating guide rail and guide it down along the guide rail body 12. During the guiding process, the servo motor 33 drives the rotating wheel 34 to rotate. The rotating wheel 34 drives the fan-shaped protrusion 35 to rotate synchronously during the rotation process. The fan-shaped protrusion 35 acts on the inflatable cushion 17. The inflatable cushion 17 realizes the expansion ball 37 to expand and shrink in the inflated and exhausted state. The expansion ball 37 acts on the inner cushion 18 to adjust the screw of the inner lower guide to avoid the screw being screwed down. After the screw is blocked, it smoothly enters the thread rolling cavity 10 and moves to the thread rolling plate position, and the thread rolling plate 7 is driven to reciprocate by the cylinder 4 to roll the screw between the thread rolling plate 7 and the thread rolling plate 2 8. After the thread rolling is completed, the downstream is collected through the discharge port 2. When the thread rolling plate is partially worn and cannot be used normally, the screw 25 is driven to rotate by the motor 24, and the screw 25 drives the ring 26 to move during the rotation, thereby achieving the purpose of adjusting the position of the thread rolling plate body 22, thereby greatly improving the utilization rate of the thread rolling plate.
