[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.

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.

[0021] Example 1, referring to Figures 1-4In the first embodiment of this utility model, a cutting assembly 1 is provided, including a support column 101, an operating table 102, a cutting machine 103, and an electric push rod 104. The upper end of the support column 101 is fixedly connected to the lower end of the operating table 102. The upper end of the operating table 102 is slidably connected to the lower end of the cutting machine 103 through a sliding groove. The rear side of the cutting machine 103 is fixedly connected to the surface of the electric push rod 104. The surface of the electric push rod 104 is fixedly connected to the inner wall of the upper end of the operating table 102. An adjustment mechanism 2 is provided at the lower end of the operating table 102, and a clamping mechanism 3 is provided at the upper end of the adjustment mechanism 2. The adjustment mechanism 2 is used to adjust according to the length of the capillary copper tube, and the clamping mechanism 3 is used to clamp the capillary copper tube.

[0022] Specifically, the cutting assembly 1 drives the cutting machine 103 to reciprocate linearly along the slide groove on the operating table 102 via the electric push rod 104, which solves the problems of uneven cuts and poor precision caused by traditional hand-held or fixed cutting. The sliding connection between the cutting machine 103 and the operating table 102 ensures the stability and consistency of the cutting process. Together with the adjustment mechanism 2 and the clamping mechanism 3, it achieves accurate positioning and reliable fixation of the pipe, effectively preventing vibration or displacement during cutting.

[0023] Furthermore, before cutting the capillary copper tube, the adjustment mechanism 2 is adjusted according to the length of the capillary copper tube, and then the clamping mechanism 3 clamps the capillary copper tube. After the copper tube is firmly clamped and positioned at the predetermined cutting position, the cutting machine 103 can be started to perform the cutting operation. Example 2, the second embodiment of this utility model, provides an adjustment mechanism 2 including a protective sleeve 201, a fixing ring 202, a servo motor 203, a double-ended screw 204, a bearing seat 205, a sliding block 206, and a fixing block 207. The surface of the protective sleeve 201 is fixedly connected to the surface of the fixing ring 202, the inner wall of the fixing ring 202 is fixedly connected to the surface of the servo motor 203, the output end of the servo motor 203 is fixedly connected to the surface of the double-ended screw 204, and the middle part of the double-ended screw 204 is connected to the inner wall of the bearing seat 205. The wall is rotatably connected, the surface of the sliding block 206 is fixedly connected to the surface of the fixed block 207, the upper end of the protective sleeve 201 is fixedly connected to the lower end of the operating table 102, the upper end of the fixing ring 202 is fixedly connected to the lower end of the operating table 102, the two ends of the double-ended screw 204 are rotatably connected to the inner wall of the protective sleeve 201, the inner wall of the sliding block 206 is threadedly connected to the surface of the double-ended screw 204, the surface of the sliding block 206 is slidably connected to the inner wall of the protective sleeve 201, and the surface of the fixed block 207 is slidably connected to the inner wall of the operating table 102 through a sliding groove.

[0024] Specifically, the adjustment mechanism 2 drives the double-ended screw 204 to rotate via the servo motor 203. By using the threads with opposite directions at both ends to cooperate with the sliding block 206, it solves the problems of low efficiency and poor synchronization in traditional manual adjustment. The double-ended screw 204 rotates stably within the bearing seat 205 and the protective sleeve 201, ensuring transmission accuracy. The sliding block 206 slides within the protective sleeve 201 and is guided by the slide groove, cooperating with the fixed block 207 to achieve high-precision linear motion. The control of the servo motor 203 can realize the adjustment of the spacing, improving adjustment efficiency and positioning accuracy.

[0025] Furthermore, the spacing of the clamping mechanism 3 needs to be adjusted according to the length of the copper tube to be processed. This adjustment process is achieved by starting the servo motor 203. The output end of the servo motor 203 is fixedly connected to a double-ended screw 204. The two ends of the double-ended screw 204 are respectively machined with threads of opposite directions, and each end is equipped with a sliding block 206 that matches the thread. The upper end of the sliding block 206 is fixedly connected to a fixing block 207. The two fixing blocks 207 support the upper clamping components respectively. When the servo motor 203 drives the double-ended screw 204 to rotate, since the threads at both ends rotate in opposite directions, the two sliding blocks 206 move synchronously in opposite directions along the guide rail under the drive of the screw, thereby driving the fixing blocks 207 at their upper ends to move towards or away from each other. By controlling the rotation angle of the servo motor 203, the distance between the two clamping positions can be adjusted, preparing for subsequent clamping and positioning. Example 3, the third embodiment of this utility model, provides a clamping mechanism 3 including a fixed rod 301, a transmission component 302, an adjusting screw 303, a clamping base plate 304, a clamping plate 305, and a fixed plate 306. The inner wall of the fixed rod 301 is movably connected to the surface of the transmission component 302. The inner sides of both ends of the transmission component 302 are drively connected to the lower surface of the adjusting screw 303. The surface of the adjusting screw 303 is rotatably connected to the inner wall of the clamping base plate 304. The inner wall of the clamping base plate 304 is slidably connected to the surface of the clamping plate 305 through a sliding groove. The fixed plate 306 is disposed on the upper end of the adjusting screw 303. The lower end of the fixed rod 301 is fixedly connected to the upper end of the fixed block 207. The surface of the fixed plate 306 is fixedly connected to the upper end of the clamping base plate 304. The inner wall of the fixed plate 306 is rotatably connected to the upper surface of the adjusting screw 303. The inner wall of the clamping plate 305 is threadedly connected to the surface of the adjusting screw 303.

[0026] Specifically, the clamping mechanism 3 solves the problems of easy eccentricity and uneven clamping force when clamping capillary copper tubes of different diameters by adjusting the screw 303, the transmission component 302 and the screws on both sides. By synchronously adjusting the lifting and lowering of the clamping plates 305 on both sides, it ensures that the axis of the copper tube does not deviate during the clamping process, thus improving the centering accuracy. The sliding groove guide cooperation between the clamping plate 305 and the clamping base plate 304 enhances the stability of movement, effectively prevents rotation or jamming, and ensures the reliability of clamping.

[0027] Furthermore, after adjusting the clamping distance, the position of the clamping plate 305 needs to be adjusted according to the specific diameter of the capillary copper tube to ensure clamping stability and alignment. During operation, the adjusting screw 303 is turned manually or by an auxiliary drive device. The rotational movement of the adjusting screw 303 is transmitted to the screws on both sides through the transmission component 302 to achieve synchronous rotation. These screws are vertically arranged, and their surfaces mate with the threads on the inner wall of the clamping plate 305. The clamping base plate 304 is rotatably connected to the screws. As the screws rotate... Rotate, and the clamping plate 305 moves up and down along the axial direction to adjust the distance between it and the clamping base plate 304. According to the outer diameter of the copper tube, the position of the clamping plate 305 is gradually adjusted until it can firmly clamp the outer wall of the copper tube to avoid displacement or deformation during processing. Since the clamping base plate 304 is firmly connected to the fixing block 207 on the aforementioned sliding block 206 through the fixing rod 301, when the servo motor 203 drives the sliding block 206 to move, the entire clamping mechanism 3 moves synchronously to ensure the accuracy of the clamping point position. Working principle: Before cutting the capillary copper tube, the spacing of the clamping mechanism 3 needs to be adjusted according to the length of the copper tube to be processed. This adjustment is achieved by starting the servo motor 203. The output end of the servo motor 203 is fixedly connected to a double-ended screw 204. The two ends of the double-ended screw 204 are machined with threads of opposite directions, and each end is equipped with a sliding block 206 that matches the thread. The upper end of the sliding block 206 is fixedly connected to a fixing block 207. The two fixing blocks 207 support the upper clamping components respectively. When the servo motor 203 drives the double-ended screw 204 to rotate, since the threads at both ends rotate in opposite directions, the two sliding blocks 206 move synchronously in opposite directions along the guide rail under the drive of the screw, thereby driving the fixing blocks 207 at their upper ends to move towards or away from each other. By controlling the rotation angle of the servo motor 203, the distance between the two clamping positions can be adjusted to prepare for subsequent clamping and positioning. After the length adjustment of the clamping spacing is completed, the position of the clamping plate 305 needs to be adjusted according to the specific diameter of the capillary copper tube. To ensure clamping stability and centering, during operation, the adjusting screw 303 is turned manually or via an auxiliary drive device. The rotational movement of the adjusting screw 303 is transmitted to the screws on both sides through the transmission component 302, achieving synchronous rotation. These screws are vertically arranged, and their surfaces mate with the threads on the inner wall of the clamping plate 305. The clamping base plate 304 is rotatably connected to the screws. As the screws rotate, the clamping plate 305 moves up and down axially, thereby adjusting the distance between it and the clamping base plate 304, according to the copper tube. The outer diameter is adjusted gradually, and the position of the clamping plate 305 is adjusted until it can firmly clamp the outer wall of the copper tube to avoid displacement or deformation during processing. Since the clamping base plate 304 is firmly connected to the fixing block 207 on the aforementioned sliding block 206 through the fixing rod 301, when the servo motor 203 drives the sliding block 206 to move, the entire clamping mechanism 3 moves synchronously to ensure the accuracy of the clamping point position. After the copper tube is firmly clamped and positioned at the predetermined cutting position, the cutting machine 103 can be started to perform the cutting operation.

[0028] In summary, the synchronous adjustment mechanism consisting of a servo motor, a double-headed screw, a sliding block, and a fixed block, in coordination with the radial clamping adjustment mechanism consisting of an adjusting screw, a transmission component, a screw, and a clamping plate, enables rapid positioning and stable clamping of capillary copper tubes of different lengths and diameters. This ensures accurate alignment and reliable fixation of the workpiece before cutting, effectively improving cutting accuracy and operational efficiency.
