[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-4 The first embodiment of this utility model provides a cutting assembly 1 including an operating table 101 and a cutting machine 102. The upper end of the operating table 101 is fixedly connected to the lower end of the cutting machine 102. A telescopic mechanism 2 is provided below the operating table 101, and a fixing mechanism 3 is provided at the upper end of the telescopic mechanism 2. The telescopic mechanism 2 is used to adjust according to the length of the half-thread screw, and the fixing mechanism 3 is used to fix the half-thread screw.

[0022] Specifically, the cutting assembly 1 solves the problems of inaccurate positioning, unstable clamping, and inconsistent length control of semi-threaded screws by fixing the cutting machine 102 to the operating table 101 and setting the telescopic mechanism 2 and the fixing mechanism 3 below. The fixing mechanism 3 achieves centering and reliable clamping of the screw, preventing loosening during processing. The telescopic mechanism 2 is driven by the electric push rod 201 and can adjust the feed stroke, realizing the coordinated operation of clamping, feeding and cutting, improving cutting accuracy, repeatability and work efficiency.

[0023] Furthermore, the half-threaded screw is fixed by the fixing mechanism 3, and adjusted according to the length of the half-threaded screw by the telescopic mechanism 2.

[0024] Example 2 The second embodiment of this utility model provides a telescopic mechanism 2 including an electric push rod 201, a fixed plate 202 and a bearing column 203. The output end of the electric push rod 201 is fixedly connected to the lower end of the rear fixed plate 202, and the upper end of the fixed plate 202 is fixedly connected to the lower end of the bearing column 203.

[0025] Specifically, the telescopic mechanism 2 uses an electric push rod 201 as a power source, and its output end is connected to the bearing column 203 via a fixed plate 202 to achieve a stable linear propulsion stroke. This structure solves the problems of uneven feeding, inaccurate positioning, and low efficiency in traditional manual feeding. It can control the screw feed distance and ensure the consistency of the cutting length each time. At the same time, the smooth output of the electric push rod 201 effectively avoids workpiece loosening or vibration caused by external force impact during the cutting process, improving operational safety and processing accuracy.

[0026] Furthermore, the electric push rod 201 is activated, and its telescopic end drives the bearing column 203 and the fixing mechanism 3 to move synchronously through the fixing plate 202, pushing the fixing mechanism 3 to move linearly along the guide rail. The operator can control the stroke of the electric push rod 201 according to the preset cutting length to send the screw to the working position of the cutting machine 102. With the stable advancement of the electric push rod 201, the screw is precisely cut in conjunction with the manual cutting machine 102, improving cutting efficiency and consistency.

[0027] Example 3 The third embodiment of this utility model provides a fixing mechanism 3 including a servo motor 301, a driving gear 302, a driven rack 303, and a fixing base 304. The output end of the servo motor 301 is fixedly connected to the inner wall of the driving gear 302. The tooth surface of the driving gear 302 meshes with the tooth surface of the driven rack 303. The upper end of the driven rack 303 is fixedly connected to the lower end of the fixing base 304. A cooperating mechanism 4 is provided at the upper end of the fixing mechanism 3. The cooperating mechanism 4 includes an adjusting screw 401 and a clamping plate 402. The surface of 401 is threaded to the inner wall of the clamping plate 402, the surface of the servo motor 301 is fixedly connected to the inner wall of the bearing column 203, the surface of the drive gear 302 is rotatably connected to the upper inner wall of the bearing column 203, the surface of the driven rack 303 is slidably connected to the upper end of the bearing column 203, the surface of the fixed seat 304 is slidably connected to the upper inner wall of the bearing column 203 through a slide groove, the surface of the adjusting screw 401 is rotatably connected to the inner wall of the fixed seat 304, and the lower end of the clamping plate 402 is slidably connected to the inner wall of the fixed seat 304 through a slide groove.

[0028] Specifically, the fixing mechanism 3 drives the active gear 302 to mesh with the driven racks 303 on both sides via the servo motor 301, so as to realize the synchronous opposite movement of the two fixed seats 304, which solves the problems of positioning eccentricity and uneven force in traditional clamping. With the clamping plate 402 structure with thread adjustment, it can adapt to semi-threaded screws of different diameters, improving the adaptability and reliability of clamping. The overall structure realizes the combination of centering and manual fine-tuning clamping, effectively avoiding workpiece loosening or displacement during cutting, and ensuring processing accuracy and operation safety.

[0029] Furthermore, firstly, the half-threaded screw to be cut is placed between the two fixed seats 304 at both ends of the operating table 101. The servo motor 301 is started, and its output end drives the drive gear 302 to rotate. The drive gear 302 meshes with two counter-arranged driven racks 303, driving the fixed seats 304 to move synchronously in the opposite direction along the guide rail, so that the two fixed seats 304 are close to the two ends of the screw, achieving initial positioning. When the fixed seats 304 are close to the surface of the screw, the servo motor 301 is stopped to ensure that the screw is axially centered, providing a stable foundation for subsequent clamping. Then, the adjusting screw 401 is manually turned, and its threaded engagement with the inner wall of the clamping plate 402 pushes the clamping plate 402 down along the internal slide groove of the fixed seat 304, gradually pressing the outer surface of the screw to achieve radial clamping and fixation, preventing the screw from axial displacement or radial vibration during cutting, and ensuring processing stability and accuracy. After the clamping plates 402 on both sides are locked, the screw is firmly fixed on the operating table 101, ready for the cutting process.

[0030] Working principle: First, place the semi-threaded screw to be cut between the fixed seats 304 at both ends of the operating table 101. Start the servo motor 301. The output end of the servo motor 301 drives the drive gear 302 to rotate. The drive gear 302 simultaneously meshes with two driven racks 303 arranged in opposite directions, thereby driving the fixed seats 304 connected to the upper end of the racks to move synchronously in opposite directions along the guide rail. This movement causes the two fixed seats 304 to gradually approach the two ends of the screw, achieving initial positioning. When the fixed seats 304 approach the surface of the screw, stop the servo motor 301 to ensure that the axial position of the screw is centered, providing a stable foundation for subsequent clamping. Then, manually turn the adjusting screw 401, utilizing its threaded engagement with the inner wall of the clamping plate 402, to push the clamping plate 402 to slide downward along the sliding groove inside the fixed seat 304. As the adjusting screw 401 is screwed in, the clamping plate... The holding plate 402 gradually presses against the outer surface of the screw to achieve radial clamping and fixation. This clamping method can effectively prevent the screw from axial displacement or radial vibration due to force during the cutting process, ensuring the stability and accuracy of the processing. After both clamping plates 402 are locked, the screw is firmly fixed on the operating table 101, ready for the cutting process. Finally, the electric push rod 201 is started. Its telescopic end drives the bearing column 203 and the fixed mechanism 3 connected to it to move synchronously through the fixed plate 202, thereby pushing the entire fixed mechanism 3 to move linearly along the guide rail. The operator can control the stroke of the electric push rod 201 according to the preset cutting length to send the screw to the working position of the cutting machine 102. With the stable advancement of the electric push rod 201, the screw is accurately cut in conjunction with the manual cutting machine 102, improving cutting efficiency and consistency.

[0031] In summary, the coordinated operation of the servo motor-driven opposing moving fixed seat, the thread-adjustable clamping mechanism, and the electric push rod-controlled feeding mechanism enables automatic positioning, reliable clamping, and feeding of semi-threaded screws, effectively ensuring the stability and processing accuracy of the cutting operation.
