[0002] A bolt is a commonly used fastener that is used with a nut through its threads to connect two or more workpieces. The main parts of a bolt include a screw rod and a nut. The screw rod is the main body of the bolt and has a spiral protrusion called a thread, while the nut has a spiral groove that matches the screw rod and is used to receive the threaded portion of the screw rod. When the bolt and nut rotate, the threads engage with each other, thereby achieving the fastening of the workpiece.

[0003] During the processing of bolts, processing machine tools are usually used for processing, wherein the machine tools mainly use turning tools to turn the rotating bolts at the parts that need to be processed.

[0004] However, there is at least one of the following problems in the related technology: during the process of processing bolts, existing machine tools usually only fix one end of the bolt at a fixed point, causing the other end of the bolt to shake during the processing, thereby making the structure of the processing part uneven, thereby affecting the processing accuracy of the bolt.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0043] The bolt 200 is a commonly used fastener. During the processing of the bolt 200, a processing machine tool is usually used for processing. In the prior art, during the processing of the bolt 200 by the processing machine tool, usually only one end of the bolt 200 is fixed at a fixed point, resulting in the other end of the bolt 200 shaking during the processing, so that the structure of the processing part is uneven, and further affecting the processing accuracy of the bolt 200.

[0044] To solve the above technical problems, as Figures 1 to 7 shown, the present utility model provides a processing machine tool for processing the bolt 200. As Figure 1 shown, the processing machine tool includes a processing platform 100, and the processing platform 100 is provided with an installation side. On this installation side, a relatively arranged first fixing structure 300 and a second fixing structure 400 are installed. Among them, the first fixing structure 300 is used to clamp one end of the bolt 200, and the second fixing structure 400 is used to fix the other end of the bolt 200, thereby increasing the stability of the bolt 200 during the processing, ensuring the uniformity of the processing part of the bolt 200, and improving the processing accuracy of the bolt 200. In addition, the second fixing structure 400 is movably connected to the installation side, so that the user can accurately adjust the distance between the first fixing structure 300 and the second fixing structure 400 during use, so that the processing machine tool can process bolts 200 of different lengths.

[0045] Furthermore, as Figures 1 to 5 shown, the bottom of the second fixing structure 400 is provided with a first slider 410, and the processing platform 100 is provided with a first slide rail 110 that slidably cooperates with the first slider 410, so that the second fixing structure 400 reciprocates in a direction close to or away from the first fixing structure 300; in addition, the processing machine tool is also provided with a first driving component electrically connected to the first slider 410 to drive the first slider 410 to reciprocate along the first slide rail 110. This increases the simplicity of the user during the operation process.

[0046] Specifically, through the cooperation mode of the slider and the slide rail, the user can precisely adjust the distance between the first fixing structure 300 and the second fixing structure 400 by gently pushing or pulling the slider. In this way, it not only increases the simplicity of the user during the operation process but also improves the accuracy during the adjustment of the distance between the first fixing structure 300 and the second fixing structure 400. Additionally, the cooperation between the first slider 410 and the second slide rail 110 has high rigidity and stability. Even during frequent movement, the stability of the connection can be maintained, thereby further increasing the stability of the bolt 200 during the processing process.

[0047] Furthermore, as Figure 4 and Figure 5 shown, a through hole 310 for the bolt 200 to pass through is provided in the first fixing structure 300. The design of the through hole 310 not only facilitates the positioning of the bolt 200 but also provides convenience for further processing operations. A first processing component 500 is provided on the side of the second fixing structure 400 away from the first fixing structure 300, ensuring that after at least part of the bolt 200 passes through the through hole 310, the first processing component 500 can perform a precise punching action on the end of the bolt 200. Compared with the prior art, this solution improves the stability and accuracy of the processing machine tool when performing a punching operation on the bolt 200.

[0048] Specifically, in the traditional processing method, when the punching component performs the punching action, only one end of the bolt 200 is fixed, and the bolt 200 may shake, which not only affects the punching accuracy but also may cause the hole-shaped structure processed on the bolt 200 to be uneven, affecting the service performance and safety of the bolt 200. In this solution, by providing the through hole 310 in the second fixing structure 400 and arranging the first processing component 500 at the end of the bolt 200, the bolt 200 can be better fixed during the punching action, thus remaining stable during the processing process. It not only improves the punching accuracy but also guarantees the overall quality of the bolt 200 processing, further enhancing the processing efficiency and reliability of the bolt 200.

[0049] Even further, as Figures 1 to 3As shown, on the side of the second fixing structure 400 away from the first fixing structure 300, there is a boss 420. Above the boss 420, there is a fixing plate 510. The first fixing plate 510 is provided with a first fixing portion 511. The first fixing portion 511 is provided with a first turning tool 520. The first turning tool 520 is arranged opposite to the through hole 310 so as to be able to perform an accurate drilling action on the end of the bolt 200 passing through the through hole 310. In addition, the second driving component 530 is arranged at a position adjacent to the first fixing portion 511 and the first turning tool 520. The second driving component 530 is connected to the first turning tool 520 by an electric wire, realizing the electrical control of the first turning tool 520. The electrical control method not only improves the machining accuracy and stability, but also reduces the need for manual operation, thus improving the machining efficiency.

[0050] Furthermore, as Figure 1 shown, the machining tool also includes a second machining component 600. The second machining component 600 is arranged on the side of the accommodation space composed of the first fixing structure 300 and the second fixing structure 400 to perform a grooving action on the side wall of the bolt 200 when the bolt 200 is fixed between the first fixing structure 300 and the second fixing structure 400. Thus, the machining process is accelerated and the production efficiency is improved.

[0051] Even further, as Figures 1 to 2 shown, the second machining component 600 includes a first support plate 610, a second support plate 620, a tool holder 630, and a second turning tool 640 arranged on the tool holder 630. Among them, the first support plate 610 is arranged on the machining platform 100 and is slidably connected to the machining platform 100; the second support plate 620 is arranged above the first support plate 610 and is slidably connected to the first support plate 610, and the second support plate 620 is provided with a second fixing portion; the tool holder 630 is arranged on the second fixing portion, and the tool holder 630 is provided with a second installation position 631; the second turning tool 640 is arranged at the second installation position 631 and is used to perform a grooving action on the side wall of the bolt 200 fixed between the first fixing structure 300 and the second fixing structure 400. The stability of the machining tool when grooving the bolt 200 is increased.

[0052] Even further, as Figures 1 to 7As shown in the figure, a second slider 621 is provided at the bottom of the second pallet 620, and a second slide rail 611 that slidably cooperates with the second slider 621 is provided on the side of the first pallet 610 away from the processing platform 100; wherein, the second slide rail 611 is disposed opposite to the bolt 200 installed between the first fixing structure 300 and the second fixing structure 400, so that the second pallet 620 drives the tool holder 630 to reciprocate on the first pallet 610 in a direction close to or away from the bolt 200; in addition, a third slider 612 is provided at the bottom of the first pallet 610, and a third slide rail 120 that slidably cooperates with the third slider 612 is provided on the installation side; wherein, the third slide rail 120 is disposed along the length direction of the bolt 200, so that the first pallet 610 drives the second pallet 620 and the tool holder 630 to reciprocate along the length direction of the bolt 200. Through the cooperation of the second slider 621 and the second slide rail 611, and the cooperation of the third slider 612 and the third slide rail 120, the tool holder 630 can move flexibly in different directions of the bolt 200 to perform grooving on different positions of the bolt 200, thereby reducing the auxiliary tools and equipment required during the processing and lowering the processing cost.

[0053] Furthermore, as Figure 7 shown, the second installation position 631 is set as a groove-shaped structure adapted to the second turning tool 640, so that the second turning tool 640 can be detachably installed on the tool holder 630. Specifically, the detachable installation method provides great convenience for the maintenance and replacement of the second turning tool 640. Setting the second installation position 631 as a groove-shaped structure ensures that the second turning tool 640 can be conveniently disassembled and installed. On the premise of ensuring the tight and stable combination of the second turning tool 640 and the tool holder 630, the disassembly process of the second turning tool 640 is also simplified. When the second turning tool 640 needs to be removed from the tool holder 630 due to damage or cleaning, the user does not need complex operations and only needs to push or pull the second turning tool 640 to easily complete the disassembly and assembly process. In addition, when the second turning tool 640 is damaged or needs to be cleaned, the user can quickly replace it, reducing the production delay caused by downtime maintenance, thereby improving the production efficiency.

[0054] Furthermore, the second processing assembly 600 further includes a third driving component and a fourth driving component. Among them, the third driving component is electrically connected to the second slider 621 to drive the second pallet 620 to drive the tool holder 630 to reciprocate on the first pallet 610 in a direction close to or away from the bolt 200; the fourth driving component is electrically connected to the third slider 612 to drive the first pallet 610 to drive the second pallet 620 and the tool holder 630 to reciprocate along the length direction of the bolt 200. Thereby reducing manual operation, accelerating the processing process, and further improving the production efficiency.

[0055] Furthermore, as Figure 1As shown, there are two second processing components 600, which are respectively arranged on both sides of the bolt 200, and the two second processing components 600 are arranged in a staggered manner.

[0056] Specifically, in a traditional processing system, there is usually only one processing component, resulting in insufficient stability of the bolt 200 during the grooving process, thus affecting the processing quality and efficiency. In this solution, through the two second processing components 600 arranged in a staggered manner, the two second processing components 600 can work together to form a mechanism of mutual complementation and reinforcement, thereby ensuring that the bolt 200 can always maintain a stable state during the grooving operation, avoiding processing quality problems caused by instability. At the same time, it helps to improve the grooving accuracy and reduce errors during the processing process.

[0057] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
