DETAILED DESCRIPTION

[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 12 As shown, in order to achieve the technical effect of "being able to process needles with different inner and outer diameters according to different application requirements", the structure and function of a thyroid puncture tool processing device are described in detail below;

[0031] A thyroid puncture tool processing device, comprising two support rings 11, wherein a sliding bracket Ⅰ12 is fixedly connected between the left and right sides of the two support rings 11, a sliding bracket Ⅱ14 is fixedly connected between the upper and lower sides of the two support rings 11, a pulling bracket 21 is slidably connected between the two sliding brackets Ⅰ12, a clamping mechanism Ⅰ30 is rotatably connected to one of the support rings 11 and the pulling bracket 21, a steel pipe 61 is clamped between the two clamping mechanisms Ⅰ30, an external molding mechanism 50 is slidably connected to the two sliding brackets Ⅱ14, a clamping mechanism Ⅱ40 is fixedly connected to the two support rings 11, an inner support rod 71 is clamped between the two clamping mechanisms Ⅱ40, and the inner support rod 71 can pass through the steel pipe 61;

[0032] The sliding bracket Ⅰ12 is rotatably connected to a screw rod Ⅰ13, and the sliding bracket Ⅰ12 is fixedly connected to a power mechanism Ⅰ for driving the screw rod Ⅰ13 to rotate, and the pulling bracket 21 is connected to the screw rod Ⅰ13 by threads;

[0033] The clamping mechanism I30 includes a rotating cavity I31, a threaded disk I32 is rotatably connected to the rotating cavity I31, a plurality of clamping blocks 33 are slidably connected to the rotating cavity I31, and the plurality of clamping blocks 33 are all connected to the threaded disk I32 by threads, and a power mechanism II for driving the rotating cavity I31 to rotate is fixedly connected to the support ring 11 and the pulling bracket 21;

[0034] The end of the clamping block 33 is provided with a plurality of clamping protrusions, and the side of the clamping block 33 is provided with a top plate;

[0035] The clamping mechanism II40 includes a telescopic mechanism I41, a mobile bracket 42 is fixedly connected to the telescopic end of the telescopic mechanism I41, a rotating cavity II43 is rotatably connected to the mobile bracket 42, a threaded disk II44 is rotatably connected to the rotating cavity II43, a plurality of clamping blocks II45 are slidably connected to the rotating cavity II43, and the plurality of clamping blocks II45 are all connected to the threaded disk II44 by threads, a power mechanism III for driving the rotating cavity II43 to rotate is fixedly connected to the mobile bracket 42, and the telescopic mechanism I41 is fixedly connected to the support ring 11;

[0036] The sliding bracket Ⅱ14 is rotatably connected to a screw rod Ⅱ15, and the sliding bracket Ⅱ14 is fixedly connected to a power mechanism Ⅳ for driving the screw rod Ⅱ15 to rotate;

[0037] The outer molding mechanism 50 includes a sliding seat 51, which is slidably connected to the sliding bracket II 14, and a telescopic mechanism II 52 is fixedly connected to the sliding seat 51, and a cooling cavity 53 is fixedly connected to the telescopic end of the telescopic mechanism II 52, and a plurality of ball cavities 55 are gap-fitted on the cooling cavity 53;

[0038] The ball cavity 55 is provided with a plurality of cooling water holes, and the ball cavity 55 is connected with the cooling cavity 53 through the cooling water holes;

[0039] The cooling cavity 53 is fixedly connected with a cooling pipe 54;

[0040] The inner support rod 71 is provided with a plurality of spiral bodies 72 wound around the support rod 71;

[0041] When in use, the steel pipe 61 to be processed is placed between the two clamping mechanisms Ⅰ30, the end of the steel pipe 61 is pressed against the top plate on the side of the clamping block 33, and the threaded disk Ⅰ32 is rotated. When the threaded disk Ⅰ32 rotates, the multiple clamping blocks 33 are driven to move through the threads, so that the multiple clamping blocks 33 are close to or away from each other, and the multiple clamping blocks 33 are close to each other to clamp the end of the steel pipe 61;

[0042] Further, the power mechanism I is started, and the power mechanism I is preferably a servo motor. The output shaft of the power mechanism I starts to rotate, and the output shaft of the power mechanism I drives the screw rod I13 to rotate. When the screw rod I13 rotates, the pulling bracket 21 is driven to move through the thread, and then the pulling bracket 21 drives the clamping mechanism I30 thereon to move, and then the position of the clamping mechanism I30 is adjusted, and the relative distance between the two clamping mechanisms I30 is adjusted, so as to adapt to steel pipes 61 of different lengths, and the two clamping mechanisms I30 can clamp steel pipes 61 of different diameters;

[0043] Furthermore, a plurality of clamping protrusions are provided at the end of the clamping block 33, thereby ensuring that the clamping block 33 can effectively clamp the steel pipe 61 and can stretch the steel pipe 61;

[0044] Further, according to the inner diameter of the needle that needs to be processed, the inner support rod 71 of different diameters is selected, and the inner support rod 71 is placed between the two clamping mechanisms II40, and the two ends of the inner support rod 71 are respectively placed on the two clamping mechanisms II40, and the threaded disk II44 is rotated. When the threaded disk II44 rotates, the clamping block II45 is driven to move through the thread, so that the clamping block II45 slides on the rotating cavity II43, and multiple clamping blocks II45 are close to or away from each other, thereby completing the clamping of the inner support rods 71 ​​of different diameters;

[0045] Further, the telescopic mechanism I41 can be started, and the telescopic mechanism I41 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I41 can drive the mobile bracket 42 to move, and the mobile bracket 42 drives the multiple clamping blocks II45 to move, so as to adjust the relative distance between the two clamping mechanisms II40, so that the two clamping mechanisms II40 can clamp the inner support rods 71 ​​of different lengths.

[0046] Furthermore, during processing, the power mechanism I is started, and the output shaft of the power mechanism I starts to rotate, and the output shaft of the power mechanism I drives the screw rod I13 to rotate. When the screw rod I13 rotates, it drives the pulling bracket 21 to move through the thread, and the pulling bracket 21 drives the clamping mechanism I30 to move, so that the distance between the two clamping mechanisms I30 is lengthened, thereby lengthening the steel pipe 61. At the same time, in order to ensure that the steel pipe 61 will not be excessively bent downward due to the influence of gravity during the elongation process, the power mechanism II is started, and the output shaft of the power mechanism II starts to rotate. The output shaft of the power mechanism II drives the rotating cavity I31 to rotate, and the rotating cavity I31 drives the steel pipe 61 to rotate when it rotates, so that the steel pipe 61 can rotate itself during the pulling process, thereby trying to offset the bending that may occur in the steel pipe 61 during the pulling process;

[0047] Further, the power mechanism IV is started, and the power mechanism IV is preferably a servo motor. The output shaft of the power mechanism IV drives the screw rod II 15 to rotate. When the screw rod II 15 rotates, it drives the sliding seat 51 to move through the thread, so that the sliding seat 51 slides on the sliding bracket II 14, and the sliding seat 51 drives the telescopic mechanism II 52 to move. The telescopic mechanism II 52 drives the cooling cavity 53 to move, and the cooling cavity 53 drives the ball cavity 55 to move. The telescopic mechanism II 52 is started. The telescopic mechanism II 52 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 52 drives the cooling cavity 53 to move, and the cooling cavity 53 drives the ball cavity 55 to move, so that the ball cavity 55 moves downward and contacts the outer side of the steel pipe 61, thereby assisting in squeezing the side of the steel pipe 61, assisting the steel pipe 61 to be pulled thinner, and thereby assisting in controlling the outer diameter of the steel pipe 61 during the stretching process;

[0048] Furthermore, the cooling pipe 54 is pre-connected with the cooling water pipe, and the cooling water is passed into the cooling pipe 54, and the cooling water enters the cooling cavity 53, and is discharged through the multiple cooling water holes on the ball cavity 55 to contact the steel pipe 61, thereby cooling the steel pipe 61 during the pulling process, ensuring the temperature of the steel pipe 61 during the processing, and thus ensuring the pulling progress of the steel pipe 61;

[0049] Furthermore, the inner support rod 71 supports the inside of the steel tube 61 to ensure the size of the inside of the steel tube 61. Furthermore, the power mechanism III is started at the same time, and the output shaft of the power mechanism III starts to rotate, and the output shaft of the power mechanism III drives the rotating cavity II 43 to rotate, and the rotating cavity II 43 drives the inner support rod 71 to rotate. Since the inner support rod 71 is long and thin, in order to ensure that the inner support rod 71 can play a supporting role and the inner support rod 71 can be deformed as little as possible, we use a rotation method to increase the strength of the inner support rod 71 when supporting.

[0050] Further, such as Fig.12 As shown, a plurality of spirals 72 are provided on the outer side of the inner support rod 71 to increase the strength of the inner support rod 71. At the same time, before processing, the power mechanism III is started in advance, and the power mechanism III drives the rotating cavity II43 to rotate, and the rotating cavity II43 drives the inner support rod 71 to rotate, one of the rotating cavities II43 rotates, and the other rotating cavity II43 does not rotate. The rotation direction of the rotating rotating cavity II43 is consistent with the direction of the spiral 72, thereby increasing the spiral of the spiral 72, and at the same time making the inner support rod 71 have a certain internal stress, thereby further increasing the strength of the inner support rod 71. In the processing process, in order to ensure the internal stress of the inner support rod 71, the two rotating cavities II43 rotate synchronously, thereby ensuring the internal stress and strength of the inner support rod 71.
