Description

Technical Field

[0001] This invention relates to the field of ultrasonic tool processing technology, specifically to a tooling for simultaneously machining ultrasonic tool holders with curved surfaces from both sides. Background Technology

[0002] As a core component of minimally invasive surgical instruments, the ultrasonic scalpel shaft's machining precision directly determines surgical safety and ultrasonic vibration transmission efficiency. It must meet stringent requirements such as high coaxiality at both ends, no surface damage, and good dimensional consistency.

[0003] Currently, ultrasonic scalpel tool holder machining mostly employs traditional single-sided step-by-step machining fixtures or simple double-sided machining devices. The fixture installation and fixing process is cumbersome, relying heavily on manual alignment and bolt tightening. This not only results in low installation efficiency but also easily leads to misalignment between the fixture and the tool holder positioning reference due to installation errors, affecting machining accuracy. The positioning structure is also simple, often using rigid clamping or single-reference positioning, which is difficult to adapt to the slender shaft-like tool holder structure, easily causing problems such as clamping deformation and positional wobbling during machining. At the same time, there is a lack of effective surface protection design, often resulting in scratches on the tool holder surface. Machining, polishing, and dust removal processes are independent of each other, requiring multiple clamping and station changes, which increases the machining cycle and reduces the surface quality and coaxiality of the two ends of the tool holder due to accumulated errors from secondary clamping. The tooling adaptability is poor, requiring the replacement of special positioning components for tool holders of different lengths and specifications, resulting in high equipment investment costs and making it difficult to meet the needs of multi-specification machining in mass production.

[0004] To address this, we propose a tooling for simultaneously machining ultrasonic scalpel shanks with curved surfaces from both sides. Summary of the Invention

[0008] Preferably, the upper and lower sides of the inner wall of the tooling frame are provided with transmission tooth grooves, and sliding connecting blocks are slidably arranged inside the two transmission tooth grooves. Polishing frames are fixedly arranged on one side of the two sliding connecting blocks, and transmission tooth grooves are provided on one side of the inner wall of the two polishing frames. Several sliding connecting blocks are also slidably arranged inside the transmission tooth grooves, and polishing servo electric cylinders are fixedly arranged on one side of the several sliding connecting blocks. Polishing blocks are fixedly arranged at one end of the drive shaft of the several polishing servo electric cylinders, and grinding belts are fixedly arranged on one side of the several polishing blocks.

[0009] Preferably, both the sliding connecting block one and the sliding connecting block two have drive gears rotatably installed inside by built-in reduction motors, and the surface of the drive gear inside the sliding connecting block one is meshed and connected to the inside of the transmission tooth groove one, and the surface of the drive gear inside the sliding connecting block two is meshed and connected to the inside of the transmission tooth groove two.

[0010] Preferably, the tooling frame is internally equipped with several limit servo cylinders, and the drive ends of the several limit servo cylinders are all fixedly equipped with limit clamps; the machining positioning frame is internally equipped with several positioning servo cylinders, and the drive ends of the several positioning servo cylinders are all fixedly equipped with positioning clamps.

[0011] Preferably, a pin servo electric cylinder is fixedly installed in the middle of the processing positioning frame located on the left side, and a positioning pin is fixedly installed at one end of the drive shaft of the pin servo electric cylinder.

[0012] Preferably, a number of processing nozzles are provided on one side of each of the two processing positioning frames, and a material guide interface is provided on the back of each of the two processing positioning frames. The interior of the material guide interface on both sides is connected to the interior of the several processing nozzles on both sides.

[0013] Preferably, the tooling frame has sliding grooves on both sides inside, and an adjusting slide plate is slidably arranged inside each of the two sliding grooves. One side of the adjusting slide plate on each side is fixedly connected to one side of the processing positioning frame. An adjusting servo motor is fixedly arranged on the outer surface of the tooling frame, and one end of the driving end of the adjusting servo motor extends into the interior of the tooling frame. An adjusting screw is rotatably arranged inside the tooling frame, and both ends of the adjusting screw are respectively threadedly connected to the interior of the two adjusting slide plates.

[0014] Preferably, a transmission helical gear is fixedly provided on the middle part of the surface of the adjusting lead screw and one end of the output shaft of the adjusting servo motor, and the tooth surfaces of the two transmission helical gears mesh for transmission; two limiting slide rods are also fixedly provided in the middle part of the tooling frame, and the two ends of the two limiting slide rods are respectively slidably connected to the inside of the two side adjusting slide plates.

[0015] Compared with existing technologies, it has the following advantages:

[0016] 1. By adopting a hinged hinge structure for the tooling frame, combined with the quick-connect design of the trajectory control frame and mounting components, the tooling frame can be inserted into the mounting slot simply by driving the mounting bracket with the servo electric cylinder, and then the telescopic positioning column cooperates with the mounting positioning hole to complete the stable installation. This greatly simplifies the tooling assembly process and avoids the reference offset problem of manual installation. When the tools on both sides are machining simultaneously, it can effectively reduce the positioning error of the tool. The positioning system adopts multiple constraint methods such as surface clamping, two-sided limit and pin hole positioning. The selective clamping of the limit clamp and the positioning clamp can avoid polishing interference. The precise cooperation between the positioning pin and the tool bar positioning hole forms a rigid reference. At the same time, the rubber pad on the surface of the clamp effectively protects the surface of the tool bar from damage. The multi-positioning coordination ensures that the tool bar has no positional wobble during the machining process, providing a reliable positioning basis for simultaneous machining on both sides. When the tool is machining forward and reverse simultaneously on both sides, the radial feed can reduce runout and maintain the axis runout fluctuation of the machining area.

[0017] 2. The two side machining positioning frames can simultaneously perform machining on both ends of the tool holder, and the machining nozzle sprays liquid in real time to assist in optimizing the machining environment; the polishing system drives the polishing frame to reciprocate and rotate the sliding connecting block through the meshing of the transmission tooth groove and the drive gear, and together with the polishing servo electric cylinder driven grinding belt, complete polishing of the tool holder surface is achieved without the need for secondary clamping and changing of work positions; the upper air blowing frame and the lower dust suction frame form a blowing and suction linkage dust cleaning mode, which can promptly remove dust generated during machining and polishing, avoid dust adhesion affecting surface quality, and the integrated design greatly shortens the processing cycle, ensuring the cleanliness and dimensional consistency of the tool holder surface polishing.

[0018] 3. By adjusting the servo motor to drive the helical gear, the adjusting screw is rotated. Utilizing the opposing threads on both sides of the screw, the adjusting slide plate slides in opposite directions along the sliding groove, thereby adjusting the distance between the two machining positioning frames. The limit slide bar ensures the stability of the adjustment process. The adjusted machining positioning frame can quickly position different specifications of tool holders using the positioning clamp and positioning pin, eliminating the need to replace special positioning components. This achieves compatible machining of multiple tool holder specifications, significantly improving the versatility of tooling, reducing equipment investment in multi-specification production, and providing an economical and efficient solution for batch processing.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1 to 8 As shown, a tooling for simultaneously machining an ultrasonic scalpel bar with a curved surface from both sides includes a tooling frame 1 and a trajectory control frame 2. The tooling frame 1 consists of two machining frames, and one side of the two machining frames is movably hinged together by a hinge. A trajectory control frame 2 is provided on one side of the tooling frame 1, and two connecting frames 3 are fixedly provided on the side of the trajectory control frame 2 near the tooling frame 1. An installation component 4 is also provided on one side of the connecting frame 3, and the installation component 4 is installed and connected to one side of the tooling frame 1. Machining positioning frames 5 are movably provided on both sides of the tooling frame 1, and a positioning groove is provided between the upper and lower machining positioning frames 5.

[0032] Furthermore, the mounting component 4 includes a mounting frame 7 and a telescopic positioning column 9. An adjusting servo cylinder is fixedly installed inside the connecting frame 3. An installation servo cylinder 6 is fixedly installed at the drive end of the adjusting servo cylinder, and a mounting frame 7 is fixedly installed at the drive end of the installation servo cylinder 6. Telescopic positioning columns 9 are movably installed on both sides of the inside of the mounting frame 7 through built-in electric push rods. Mounting grooves 8 are provided on both sides of the surface of the tooling frame 1, and mounting positioning holes 10 that cooperate with the telescopic positioning columns 9 are provided on both sides of the inside of the two mounting grooves 8.

[0033] It should be noted that a rotating connecting column is provided on one side of the trajectory control frame 2. First, the rotating connecting block on one side of the trajectory control frame 2 is connected to the output shaft of the rotary control motor in the processing area. After the ultrasonic scalpel bar is clamped and positioned inside the two trajectory control frames 2, the tooling frame 1 is placed between the two connecting frames 3 on both sides. The drive end of the mounting servo cylinder 6 is used to control the mounting frame 7 to insert into the mounting groove 8 on the surface of the tooling frame 1. Then, the telescopic positioning column 9 inside the mounting frame 7 is controlled to insert into the mounting positioning hole 10, completing the installation connection between the tooling frame 1 and the trajectory control frame 2, ensuring the stability of the ultrasonic scalpel bar during processing. When both sides of the tool are processed simultaneously, the positioning error of the tool can be effectively reduced. The output shaft of the rotary control motor drives the trajectory control frame 2 to swing regularly in the X-axis direction. At the same time, the drive end of the servo cylinder is adjusted to control the installation servo cylinder 6 to move back and forth. The drive end of the installation servo cylinder 6 drives the tooling frame 1 to move up and down, thereby realizing the curved motion of the workpiece in the Y-axis direction. The combination of the above-mentioned X-axis direction motion, Y-axis direction motion and CNC motion of the machine tool realizes the processing of ultrasonic tool holder with curved surface. The simultaneous processing of both sides of the tool in forward and reverse directions can reduce the runout and maintain the axial runout fluctuation of the processing area.

[0034] Specifically, air blowing frames 11 are fixedly installed on both sides of the upper fixture 1, and an air inlet 12 is also provided on the back of the upper fixture 1. The interior of the air inlet 12 is connected to the interior of the two air blowing frames 11 respectively. Clean gas is introduced into the interior of the two air blowing frames 11 through the air blowing frames 11 to blow away dust from the surface of the ultrasonic scalpel rod, ensuring the polishing quality of the ultrasonic scalpel rod surface. Dust collection frames 13 are fixedly installed on both sides of the lower fixture 1, and a dust collection interface 14 is also provided on the back of the lower fixture 1. The interior of the dust collection interface 14 is connected to the interior of the two dust collection frames 13 respectively. The dust collection interface 14, in conjunction with the two dust collection frames 13, extracts the processing dust inside the fixture 1, further ensuring the surface polishing quality of the ultrasonic scalpel rod.

[0035] It should be noted that by using two machining frame hinges to connect the tooling frame 1, the opening and closing of the tooling is facilitated, providing convenience for the placement and removal of the ultrasonic scalpel rod. The trajectory control frame 2 can be fixed to the machining area with bolts, and its connecting frame 3, in conjunction with the mounting component 4, connects to the tooling frame 1. The mounting servo cylinder 6 drives the mounting frame 7 to insert into the mounting groove 8 on the surface of the tooling frame 1. Then, through the cooperation of the telescopic positioning post 9 inside the mounting frame 7 and the mounting positioning hole 10, the installation connection between the tooling frame 1 and the trajectory control frame 2 can be securely completed, effectively ensuring the ultrasonic scalpel rod. The structural stability during processing; the machining positioning frames 5 and the positioning grooves on both sides of the tooling frame 1 can be used to clamp and position the ultrasonic scalpel rod, providing a precise positioning basis for simultaneous processing on both sides; in addition, the air blowing frame 11 located on the upper tooling frame 1 introduces clean gas through the air inlet 12, which can blow dust off the surface of the ultrasonic scalpel rod, while the dust suction frame 13 located on the lower tooling frame 1 extracts the dust generated during processing through the dust suction 14. The two work together to help reduce the interference of dust on the processing process and ensure the surface polishing quality of the ultrasonic scalpel rod.

[0036] Example 2

[0037] Specifically, the upper and lower sides of the inner wall of the tooling frame 1 are provided with transmission tooth grooves 15, and sliding connecting blocks 16 are slidably arranged inside the two transmission tooth grooves 15. Polishing frames 17 are fixedly arranged on one side of the two sliding connecting blocks 16, and transmission tooth grooves 18 are provided on one side of the inner wall of the two polishing frames 17. Several sliding connecting blocks 19 are also slidably arranged inside the transmission tooth grooves 18, and polishing servo cylinders 20 are fixedly arranged on one side of the several sliding connecting blocks 19. Polishing blocks 21 are fixedly arranged at one end of the drive shaft of the several polishing servo cylinders 20, and grinding belts 22 are fixedly arranged on one side of the several polishing blocks 21. Drive gears 23 are rotatably arranged inside the sliding connecting blocks 16 and the sliding connecting blocks 19 through built-in reduction motors. The surface of the drive gear 23 inside the sliding connecting block 16 meshes with the inside of the transmission tooth groove 15, and the surface of the drive gear 23 inside the sliding connecting block 19 meshes with the inside of the transmission tooth groove 18.

[0038] It should be noted that after the ultrasonic scalpel bar is positioned inside the fixture 1, the polishing frames 17 inside the two fixtures 1 engage with each other on opposite sides. At this time, the transmission gear grooves 18 inside the two polishing frames 17 form a complete annular groove. When the ultrasonic scalpel bar is processing synchronously on both sides, the drive gear 23 inside the sliding connecting block 16 and the transmission gear groove 15 engage to drive the polishing frame 17 to reciprocate left and right inside the fixture 1. This is coordinated with the drive gear 23 inside the sliding connecting block 19 and the transmission gear groove 18 to engage and drive the sliding connecting block 19 to reciprocate left and right within the transmission gear groove 18. The inside of groove 218 rotates, and the drive end of polishing servo cylinder 20 controls the polishing block 21 to approach the surface of the ultrasonic scalpel rod until the grinding belt 22 on one side of the polishing block 21 contacts the surface of the ultrasonic scalpel rod. The grinding belt 22 is driven to rotate on the surface of the ultrasonic scalpel rod by sliding connecting block 219. At the same time, sliding connecting block 16 slides inside the transmission tooth groove 15, thereby achieving complete polishing of the surface of the ultrasonic scalpel rod. In conjunction with the air blowing frame 11 and the dust suction frame 13, the polishing dust on the surface of the ultrasonic scalpel rod is effectively cleaned, thereby ensuring the surface polishing cleanliness of the ultrasonic scalpel rod.

[0039] Furthermore, the tooling frame 1 is internally equipped with several limit servo cylinders 24, and the drive ends of the limit servo cylinders 24 are all fixedly equipped with limit clamps 25; the machining positioning frame 5 is internally equipped with several positioning servo cylinders 26, and the drive ends of the positioning servo cylinders 26 are all fixedly equipped with positioning clamps 27; wherein, a rubber pad is provided on one side of both the limit clamps 25 and the positioning clamps 27 to protect the surface quality of the ultrasonic scalpel handle.

[0040] Furthermore, a pin servo cylinder 28 is fixedly installed in the middle of the machining positioning frame 5 located on the left side, and a positioning pin 29 is fixedly installed at one end of the drive shaft of the pin servo cylinder 28; wherein, the diameter of the positioning pin 29 matches the positioning pin hole at one end of the ultrasonic scalpel rod.

[0041] It should be noted that when simultaneously machining both sides of the ultrasonic scalpel rod, the driving ends of several limit servo cylinders 24 are first used to control the limit clamping plates 25 to clamp and position the surface of the ultrasonic scalpel rod. According to the sliding position of the polishing frame 17, the driving ends of the limit servo cylinders 24, in conjunction with the limit clamping plates 25, selectively control the clamping and positioning of the ultrasonic scalpel rod to avoid interference from the sliding of the polishing frame 17 caused by the limit clamping plates 25. At the same time, the driving ends of the positioning servo cylinders 26 inside the machining positioning frames 5 on both sides, in conjunction with the positioning clamping plates 27, clamp and position both sides of the ultrasonic scalpel rod. Meanwhile, the driving end of the left-side pin servo cylinder 28 controls the positioning pin 29 to clamp and limit the positioning pin hole at one end of the ultrasonic scalpel rod, preventing the ultrasonic scalpel rod from shaking during machining, thereby effectively improving the machining accuracy of both sides of the ultrasonic scalpel rod simultaneously.

[0042] Furthermore, several processing nozzles 30 are provided on one side of each of the two processing positioning frames 5, and a material guide interface 31 is provided on the back of each of the two processing positioning frames 5. The interior of the material guide interface 31 on both sides is connected to the interior of the several processing nozzles 30 on both sides. It should be noted that liquid spraying is performed on both sides of the ultrasonic scalpel bar through the processing nozzles 30 provided inside the two processing positioning frames 5.

[0043] It should be noted that the transmission gear 15 on the inner wall of the fixture 1 meshes with the drive gear 23 inside the sliding connecting block 16, driving the polishing frame 17 to reciprocate left and right within the fixture 1. Simultaneously, the transmission gear 18 on the inner wall of the polishing frame 17 engages with the drive gear 23 inside the sliding connecting block 19, causing the sliding connecting block 19 to rotate. Combined with the polishing block 21 connected to the drive end of the polishing servo cylinder 20 and its grinding belt 22, complete polishing of the ultrasonic scalpel handle surface can be achieved. This polishing process, combined with the previously used air blowing frame 11 and dust suction frame 13, effectively cleans polishing dust, ensuring the cleanliness of the ultrasonic scalpel handle surface. The limiting servo cylinder 24 inside the fixture 1 drives the limiting clamp 25, which can... Selective clamping and positioning of the ultrasonic scalpel bar surface avoids interference with the sliding of the polishing frame 17. The positioning servo cylinder 26 inside the machining positioning frame 5 drives the positioning clamping plate 27, which, together with the positioning pin 29 driven by the pin servo cylinder 28 inside the left machining positioning frame 5, can stably limit the positioning pin holes on both sides and one end of the ultrasonic scalpel bar, preventing the bar from wobbling during processing. The rubber pads on one side of the limiting clamping plate 25 and the positioning clamping plate 27 can protect the surface quality of the ultrasonic scalpel bar, helping to improve the accuracy of simultaneous processing on both sides of the bar. In addition, the processing nozzles 30 on one side of the machining positioning frames 5 on both sides are connected through the material guide interface 31, which can spray liquid while processing both sides of the ultrasonic scalpel bar, thus helping to optimize the processing.

[0044] Example 3

[0045] Specifically, both sides of the tooling frame 1 are provided with sliding grooves 32, and adjusting slide plates 33 are slidably arranged inside the two sliding grooves 32. One side of the adjusting slide plates 33 on both sides is fixedly connected to one side of the processing positioning frame 5. An adjusting servo motor 37 is fixedly arranged on the outer surface of the tooling frame 1, and one end of the driving end of the adjusting servo motor 37 extends into the interior of the tooling frame 1. An adjusting screw 34 is rotatably arranged inside the tooling frame 1, and both ends of the adjusting screw 34 are respectively connected to the internal threads of the two adjusting slide plates 33. The adjusting screw 34 has external threads with opposite directions on both sides of its surface. When the adjusting screw 34 rotates clockwise, the adjusting slide plates 33 on both sides slide outward from the interior of the sliding grooves 32 on both sides.

[0046] Furthermore, a transmission helical gear 36 is fixedly installed on the middle part of the surface of the adjusting screw 34 and one end of the output shaft of the adjusting servo motor 37, and the tooth surfaces of the two transmission helical gears 36 mesh for transmission; two limiting slide rods 35 are also fixedly installed in the middle part of the tooling frame 1, and the two ends of the two limiting slide rods 35 are respectively slidably connected to the inside of the adjusting slide plates 33 on both sides.

[0047] It should be noted that when performing synchronous processing on both sides of ultrasonic scalpel bars of different lengths and sizes, the output shaft of the servo motor 37 is adjusted in conjunction with two meshing transmission helical gears 36 to control the rotation of the adjusting screw 34. The clockwise rotation of the adjusting screw 34 controls the two adjusting slide plates 33 to slide out from the inside of the two sliding grooves 32, thereby adjusting the distance between the two processing positioning frames 5. The two processing positioning frames 5 on both sides are used to process and position the processing areas on both sides of the ultrasonic scalpel bar. The positioning clamps 27 inside the two processing positioning frames 5 are used to clamp and position the ultrasonic scalpel bar. At the same time, the drive end of the left-side pin servo electric cylinder 28 controls the positioning pin 29 to position and connect to the positioning pin hole on the ultrasonic scalpel bar. The position of the two processing positioning frames 5 on both sides is adaptively processed and positioned by adjusting the slide plates 33, which improves the applicability of the ultrasonic scalpel bar processing fixture.

[0048] It should be noted that the sliding grooves 32 on both sides of the tooling frame 1 provide a stable sliding guide for the adjusting slide plate 33. The fixed connection between the adjusting slide plate 33 and the machining positioning frame 5 allows the position of the machining positioning frame 5 to be adjusted synchronously with the adjusting slide plate 33. The output shaft of the adjusting servo motor 37 can stably drive the adjusting screw 34 to rotate through two meshing transmission helical gears 36. Combined with the opposite external threads on both sides of the adjusting screw 34, it can drive the two adjusting slide plates 33 to slide in opposite directions along the sliding grooves 32, thereby flexibly adjusting the distance between the two machining positioning frames 5 and adapting to different length gauges. The tooling frame 1 is designed to meet the processing requirements of ultrasonic scalpel bar. Two limiting slide rods 35 in the center of the tooling frame 1 are slidably connected to the adjusting slide plate 33, further enhancing the stability of the adjusting slide plate 33 during sliding and preventing it from shifting. This adjustment structure, combined with the positioning clamps 27 inside the two side processing positioning frames 5 and the positioning pins 29 driven by the left-side pin servo electric cylinder 28, allows the adjusted processing positioning frame 5 to accurately clamp and position the processing areas on both sides of ultrasonic scalpel bars of different specifications, effectively improving the tooling's applicability to processing ultrasonic scalpel bars of different specifications, while ensuring the stability of the bar's positioning during processing.

[0049] Example 4

[0050] Specifically, this embodiment also discloses the working principle of a tooling for simultaneously machining ultrasonic scalpel shanks with curved surfaces on both sides, including the following steps:

[0051] First, fix the two trajectory control frames 2 to the processing area with bolts. Utilize the opening and closing characteristics of the tooling frame 1, which is hinged by the two processing frames, to open the tooling frame 1 and insert the ultrasonic scalpel rod inside. Then, place the tooling frame 1 between the two connecting frames 3 on both sides. Start the installation assembly 4, and drive the installation servo cylinder 6 to insert the installation frame 7 into the installation groove 8 on the surface of the tooling frame 1. Then, control the telescopic positioning column 9 inside the installation frame 7 to extend and insert into the installation positioning hole 10, thus completing the stable connection between the tooling frame 1 and the trajectory control frame 2, providing basic stability for the processing process.

[0052] The machining positioning frame 5 and the positioning grooves therein first limit the tool bar. Then, several limiting servo electric cylinders 24 inside the tooling frame 1 drive the limiting clamping plate 25 to clamp the surface of the tool bar. The clamping position can be selectively adjusted according to the sliding path of the subsequent polishing frame 17 to avoid interfering with the polishing action. At the same time, the positioning servo electric cylinders 26 inside the machining positioning frames 5 on both sides drive the positioning clamping plate 27 to further clamp the tool bar from both sides. The pin servo electric cylinder 28 inside the left machining positioning frame 5 synchronously drives the positioning pin 29 to insert into the positioning pin hole at one end of the tool bar, forming multiple fixation of surface clamping, limiting on both sides and pin hole positioning. The rubber pads on one side of the limiting clamping plate 25 and the positioning clamping plate 27 can avoid damaging the surface of the tool bar, ensuring positioning stability and surface integrity.

[0053] The machining positioning frames 5 on both sides of the tooling perform synchronous machining for the machining requirements at both ends of the tool holder. At the same time, the appropriate machining liquid is introduced into the machining nozzle 30 through the material guide interface 31 on the back of the machining positioning frame 5. The machining nozzle 30 sprays liquid synchronously during the machining process to help optimize the machining environment and machining effect.

[0054] After the tool holder is positioned, the polishing frames 17 in the two tool holders 1 are fitted together, and the transmission tooth grooves 18 on their inner walls form a complete annular groove. Through the meshing of the drive gear 23 inside the sliding connecting block 16 with the transmission tooth groove 15, the polishing frame 17 is driven to reciprocate left and right in the tool holder 1. At the same time, the drive gear 23 inside the sliding connecting block 19 meshes with the transmission tooth groove 18, driving the sliding connecting block 19 to rotate along the annular groove. The polishing servo cylinder 20 drives the polishing block 21 to approach the tool holder surface, so that the grinding belt 22 is in close contact with the tool holder surface. Under the synergistic effect of the reciprocating motion of the polishing frame 17 and the rotation of the sliding connecting block 19, the complete polishing of the tool holder surface is achieved. During this process, the air inlet 12 of the upper tool holder 1 introduces clean gas, which blows dust onto the tool holder surface through the air blowing frame 11. The dust suction interface 14 of the lower tool holder 1 works with the dust suction frame 13 to extract the dust generated during processing and polishing. The two work together to reduce the interference of dust on the polishing quality.

[0055] The servo motor 37 is started, and its output shaft drives the adjusting screw 34 to rotate through two meshing helical gears 36. Since the adjusting screw 34 has external threads with opposite directions on both sides of its surface and its two ends are threadedly connected to the adjusting slide plate 33, the adjusting slide plate 33 slides in opposite directions along the sliding groove 32 inside the tooling frame 1, thereby driving the machining positioning frame 5, which is fixedly connected to the adjusting slide plate 33, to adjust the spacing. The limiting slide rod 35 inside the tooling frame 1 slides in cooperation with the adjusting slide plate 33 to ensure the stability of the adjustment process, so that the adjusted machining positioning frame 5 can accurately adapt to the machining area of ​​tool holders of different lengths. Then, the positioning is completed by the cooperation of the positioning clamp 27 and the positioning pin 29, realizing the compatible machining of tool holders of multiple specifications.
