Description

Technical Field

[0001] This invention relates to the field of tooling technology for tooling for cutting tools, specifically a tooling and method for machining tooling parts. Background Technology

[0002] In the field of mechanical manufacturing, the cutter shaft is a core transmission component for various machine tools to perform cutting, drilling, and other machining operations. Its structural precision directly affects the overall machining performance and the quality of the finished workpiece. With the increasing demand for diversified and high-precision parts in modern industry, the specifications and types of cutter shafts are becoming more and more numerous. Different models of cutter shafts have significant differences in size and structure (such as the position of the center hole and the distribution of the holes and slots to be machined). This places stringent requirements on the positioning and clamping fixtures during the cutter shaft machining process.

[0003] Currently, existing tool shaft machining relies heavily on specialized tooling. When machining tool shafts of different sizes, different fixtures need to be changed for clamping, which is cumbersome, reduces efficiency, and makes it difficult to adjust the clamping position of the fixtures. This reduces the overall applicability of the machining tooling, affects the clamping accuracy of the tooling on the parts, and increases the risk of workpiece machining. Summary of the Invention

[0004] To address the technical problems of requiring different fixtures for clamping in machining tool shafts of different sizes, which is cumbersome, inefficient, and makes it difficult to adjust the clamping position, thus reducing the overall applicability of the machining fixture, affecting the clamping accuracy of the fixture on the parts, and increasing the risk of workpiece machining, this invention provides a tooling fixture and machining method for machining tool shaft parts.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a tooling and method for machining a tool shaft part, wherein the tooling for machining the tool shaft part includes: A processing table, with a fixed base installed at the left end of the processing table, and a clamping assembly for clamping and fixing cutter shaft bodies of different sizes is installed on the surface of the fixed base; A slide rail, which is fixedly installed on the top side of the processing table; A positioning mechanism is slidably mounted on the top side surface of the machining table. The positioning mechanism is used to press the center of one end of the tool shaft body. The positioning mechanism cooperates with the clamping assembly for fixing and clamping the tool shaft body. An auxiliary support unit is movably disposed on the slide rail surface and is used to assist in supporting the cutter shaft body to be processed. An auxiliary clamping mechanism is movably mounted on the slide rail surface and is used to assist in clamping and fixing the cutter shaft body. A dustproof sleeve is provided, which can be connected to an auxiliary clamping mechanism and an auxiliary support unit. The dustproof sleeve is installed on the top side of the slide rail and is used to prevent waste material from the machining cutter shaft body from falling onto the slide rail surface.

[0006] Furthermore, the clamping assembly includes a spindle, a hydraulic three-jaw chuck, jaws, clamping blocks, and a positioning head. The spindle is mounted on the surface of the fixed base. One end of the spindle can be connected to the drive end of the machine tool motor, and the other end of the spindle is fixedly mounted with a hydraulic three-jaw chuck. The clamping end of the hydraulic three-jaw chuck is equipped with jaws, and the inner wall of the jaws is bolted with clamping blocks. The positioning head is fixedly mounted at the center position of the hydraulic three-jaw chuck.

[0007] Furthermore, there are two slide rails, which are mounted on the surface of the processing table, and the slide rails are provided with multiple threaded holes at equal intervals.

[0008] Furthermore, the positioning mechanism includes a lead screw, a drive seat, a mounting seat, a support platform, a clamping seat, and a clamping head. A lead screw seat is installed on the top of the processing table, and a lead screw passes through the surface of the lead screw seat. A drive seat is threaded onto the surface of the lead screw. The top side of the drive seat is fixedly connected to a mounting seat that can slide on the surface of the slide rail. A support platform is installed on the top side surface of the mounting seat by bolts. A clamping seat is fixedly installed on the top of the support platform, and a clamping head for clamping the end of the cutter shaft body is installed on the side surface of the clamping seat. The mounting base has a locking bolt threaded through its top surface, and the end of the locking bolt can be threadedly connected to the corresponding threaded hole on the top side of the slide rail.

[0009] Furthermore, the auxiliary support unit includes a movable slide, a lead screw, a movable seat, and a support member. The movable slide is slidably connected to the top surface of the slide rail. A lead screw passes through the side surface of the movable slide. A movable seat is threaded onto the surface of the lead screw. The movable seat is slidably connected to the top side of the movable slide. A support member for supporting the cutter shaft body is installed on the top side of the movable seat. A fixing bolt passes through the surface of the movable slide. The end of the fixing bolt passes vertically through the top side of the movable slide and can be threadedly connected to the threaded hole of the slide rail. The lead screw surface is threaded with two movable seats, and the two movable seats are threaded in opposite directions to the lead screw.

[0010] Furthermore, the support includes a connecting platform, a connecting shaft, and a support ring. Two parallel connecting platforms are fixedly installed on the top side of the movable seat. The two connecting platforms are rotatably connected by the connecting shaft. The support ring is rotatably sleeved on the surface of the connecting shaft, and the support ring is in contact with the main body of the cutter shaft.

[0011] Furthermore, a hydraulic drive assembly is installed on the outside of the auxiliary clamping mechanism. The auxiliary clamping mechanism includes an auxiliary seat, a limiting rail, a moving rail, a fixed clamping plate, and a pressure block. The auxiliary seat is slidably installed on the top surface of the slide rail, and a fastening bolt is threaded through the top of the auxiliary seat. A limiting rail is installed on the top of the auxiliary seat, and a moving rail is slidably connected to the inner cavity of the limiting rail. The top side of the moving rail is fixedly connected to the fixed clamping plate by bolts. A pressure block is detachably installed on the inner wall of the fixed clamping plate. Two pressure blocks are installed on the inner wall of the fixed clamping plate. The pressure blocks are fixedly connected to the fixed clamping plate by bolts. The two pressure blocks form a V-shaped structure and are in contact with the side surface of the cutter shaft body.

[0012] Furthermore, the dustproof cover includes multiple protective shells, rubber sealing gaskets, and connecting seats. The multiple protective shells are nested together. A limiting groove is formed on the inner wall of the protective shell. The limiting groove is slidably connected to a limiting block fixed on the outer side of another corresponding protective shell. The rubber sealing gasket is fixedly connected to the inner wall of the other end of the protective shell. The rubber sealing gasket fits against the outer side of the nested protective shell.

[0013] Furthermore, two air blowing mechanisms are fixedly installed on the top side surface of the machining table, which are symmetrically distributed about the tool axis. The air blowing mechanism includes a fixed frame fixedly installed on the top side of the machining table, an air outlet pipe installed on the surface of the fixed frame, and nozzles evenly distributed on the side surface of the air outlet pipe.

[0014] A machining method for a tooling fixture for machining a cutter shaft part, the machining method for the tooling fixture for machining a cutter shaft part includes the following steps: 1. Based on the length, diameter, and other dimensions of the cutter shaft body to be processed, pre-adjust the positions of each component on the processing table. Specifically, slide the movable slide along the slide rail to position it at the corresponding machining position of the cutter shaft body. Secure the movable slide to the threaded hole of the slide rail with fixing bolts. Then rotate the lead screw. Since the two movable seats are connected to the lead screw in opposite directions, the distance between the two movable seats can be adjusted so that the support ring of the support component is adapted to the diameter of the cutter shaft body, ensuring that the support ring fits against the surface of the cutter shaft body, thus achieving support of the cutter shaft body by the support ring. 2. Align one end of the cutter shaft body with the clamping assembly, aligning the center of the cutter shaft end with the positioning head of the hydraulic three-jaw chuck; activate the hydraulic three-jaw chuck, the jaws drive the clamping blocks to retract synchronously, clamping the cutter shaft end through the clamping blocks; rotate the lead screw of the positioning mechanism, the drive seat drives the mounting seat to move along the slide rail to the other end of the cutter shaft, until the clamping head on the clamping seat clamps the center of the cutter shaft end; tighten the fastening bolts to fix the mounting seat to the slide rail. Through the cooperation of the clamping assembly and the positioning mechanism, the concentric fixation of both ends of the cutter shaft is achieved, ensuring coaxiality during machining; 3. The auxiliary seat slides along the slide rail to position the cutter shaft body at the location where it needs to be clamped and fixed (such as near the machining section). The auxiliary seat is fixed to the slide rail by fastening bolts. The hydraulic drive component drives the moving rail to slide along the limit rail, which moves the fixed clamping plate closer to the cutter shaft, so that the V-shaped pressure block fits against the surface of the cutter shaft to achieve auxiliary clamping. 4. The spindle is connected to the machine tool motor drive end. After the motor starts, the spindle drives the hydraulic three-jaw chuck and the clamped cutter shaft body to rotate synchronously, providing rotational power for external cylindrical machining, milling and other processes. The support ring of the auxiliary support unit rotates with the cutter shaft, continuously supporting the middle of the cutter shaft and preventing the long cutter shaft body from bending due to its own weight. The V-shaped pressure block of the auxiliary clamping mechanism maintains the clamping force on the cutter shaft body, reducing the impact of machining vibration on accuracy. 5. Waste materials generated during processing (such as iron filings) are blocked by the dustproof cover to prevent them from falling onto the slide rail surface (preventing the slide rail from jamming); at the same time, the air blowing mechanism on the processing table sprays gas through the nozzle of the air outlet pipe to clean the waste materials on the processing surface of the cutter shaft body, ensuring a clear processing view and reducing the interference of waste materials on processing accuracy. 6. After processing is completed, release the pressure block of the auxiliary clamping mechanism, the top clamping head of the positioning mechanism, and the jaws of the clamping component in sequence, and remove the processed cutter shaft body; each auxiliary component can be reset along the slide rail, and the dustproof sleeve retracts as the components move, thus completing the processing.

[0015] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0016] The positive and progressive effects of this invention are as follows: The aforementioned tooling and machining method for machining cutter shaft parts, through the combined action of a positioning mechanism, an auxiliary support unit, and an auxiliary clamping mechanism, can adapt to the machining of various types of cutter shafts, reduce the number of fixture changes, lower production costs, adapt to the positional deviation of the center hole of the part, improve the positioning accuracy of the cutter shaft machining, simplify the disassembly and assembly process, save time, and improve machining efficiency. At the same time, the cutter shaft body has holes and slots that can be marked in red. The red visual markings can clearly indicate the parts that need to be machined, making it convenient for operators to identify and reducing the difficulty of operation. Furthermore, the rubber sealing gasket fixed to the inner wall of the other end of the protective shell is always in close contact with the outer side of the other protective shell during the expansion and contraction of the protective shell, forming a continuous sealing structure. This can effectively block metal shavings, coolant and other waste generated during the processing, prevent them from falling onto the slide rail surface, avoid the accumulation of waste affecting the sliding accuracy of the slide rail, and at the same time reduce the wear of impurities on the slide rail, thus extending the service life of the slide rail.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0033] Example 1: As Figure 1-12 As shown, the tooling fixture for machining the cutter shaft part includes: A processing table 1, with a fixed base 2 installed at the left end of the processing table 1, and a clamping assembly 3 for clamping and fixing the cutter shaft body 8 of different sizes is installed on the surface of the fixed base 2; The slide rail 5 is fixedly installed on the top side of the processing table 1; Positioning mechanism 4 is slidably disposed on the top side surface of processing table 1. Positioning mechanism 4 is used to press the center of one end of the tool shaft body 8. Positioning mechanism 4 cooperates with clamping assembly 3 for fixing and clamping the tool shaft body 8. Auxiliary support unit 6 is movably disposed on the surface of slide rail 5 and is used to assist in supporting the cutter shaft body 8 to be processed. An auxiliary clamping mechanism 7 is movably mounted on the surface of the slide rail 5 and is used to assist in clamping and fixing the cutter shaft body 8. Dustproof sleeve 9, which can be connected to auxiliary clamping mechanism 7 and auxiliary support unit 6, is provided on the top side of slide rail 5. The dustproof sleeve 9 is used to prevent the waste material of machining cutter shaft body 8 from falling onto the surface of slide rail 5.

[0034] Specifically, the cutter shaft body 8 has holes and slots that can be marked in red. The red visual markings can clearly indicate the parts that need to be processed, making it easy for operators to identify and reducing the difficulty of operation.

[0035] refer to Figure 1 As shown, the clamping assembly 3 includes a spindle 31, a hydraulic three-jaw chuck 32, jaws 33, clamping blocks 34, and a positioning head 35. The spindle 31 is mounted on the surface of the fixed base 2. One end of the spindle 31 can be connected to the machine tool motor drive end, and the other end of the spindle 31 is fixedly mounted with the hydraulic three-jaw chuck 32. The clamping end of the hydraulic three-jaw chuck 32 is equipped with jaws 33. The inner wall of the jaws 33 is bolted with clamping blocks 34. The positioning head 35 is fixedly mounted at the center position of the hydraulic three-jaw chuck 32. The spindle 31 is connected to the machine tool motor drive end. After the motor starts, the spindle 31 drives the hydraulic three-jaw chuck 32 and the clamped tool shaft body 8 to rotate synchronously, providing rotational power for external cylindrical machining, milling and other processes.

[0036] There are two slide rails 5, which are mounted on the surface of the processing table 1. The surface of each slide rail 5 has multiple threaded holes at equal intervals.

[0037] like Figures 1-7 As shown, the positioning mechanism 4 includes a lead screw 41, a drive seat 42, a mounting seat 43, a support platform 44, a clamping seat 45, and a clamping head 46. The top of the processing table 1 is equipped with a lead screw 41 seat, through which the lead screw 41 passes. The drive seat 42 is threaded onto the surface of the lead screw 41. The top side of the drive seat 42 is fixedly connected to the mounting seat 43, which can slide on the surface of the slide rail 5. The support platform 44 is bolted to the top side surface of the mounting seat 43. The clamping seat 45 is fixedly installed on the top of the support platform 44, and the clamping head 46 for clamping the end of the cutter shaft body 8 is installed on the side surface of the clamping seat 45. The mounting base 43 has a locking bolt threaded through its top surface, and the end of the locking bolt can be threadedly connected to the corresponding threaded hole on the top side of the slide rail 5.

[0038] Align one end of the cutter shaft body 8 with the clamping assembly 3, aligning the center of the cutter shaft end with the positioning head 35 of the hydraulic three-jaw chuck 32. Activate the hydraulic three-jaw chuck 32, causing the jaws 33 to synchronously retract the clamping blocks 34, clamping the cutter shaft end. The clamping blocks 34 are removable and replaceable to accommodate cutter shaft bodies 8 of different sizes. Rotate the lead screw 41 of the positioning mechanism 4, causing the drive seat 42 to move the mounting seat 43 along the slide rail 5 towards the other end of the cutter shaft until the clamping head 46 on the clamping seat 45 clamps the center of the cutter shaft end. Tighten the fastening bolts to fix the mounting seat 43 to the slide rail 5. Through the cooperation of the clamping assembly 3 and the positioning mechanism 4, the concentric fixation of both ends of the cutter shaft is achieved, ensuring coaxiality during machining.

[0039] like Figure 5 and Figure 9 As shown, the auxiliary support unit 6 includes a movable slide 61, a lead screw 62, a movable seat 63, and a support member. The movable slide 61 is slidably connected to the top surface of the slide rail 5. The lead screw 62 passes through the side surface of the movable slide 61. The movable seat 63 is threaded onto the surface of the lead screw 62. The movable seat 63 is slidably connected to the top side of the movable slide 61. A support member for supporting the cutter shaft body 8 is installed on the top side of the movable seat 63. A fixing bolt passes through the surface of the movable slide 61. The end of the fixing bolt passes vertically through the top side of the movable slide 61 and can be threadedly connected to the threaded hole of the slide rail 5. The lead screw 62 has two movable seats 63 threadedly connected to its surface, and the two movable seats 63 are threaded in opposite directions to the lead screw 62.

[0040] During use, the movable slide 61 slides along the slide rail 5 to position it at the desired machining position on the cutter shaft body 8. The movable slide 61 is then locked and fixed to the threaded hole of the slide rail 5 by fixing bolts. Then, the lead screw 62 is rotated. Since the two movable seats 63 are connected to the lead screw 62 in opposite directions, the distance between the two movable seats 63 can be adjusted so that the support ring 66 of the support component is adapted to the diameter of the cutter shaft body 8, ensuring that the support ring 66 fits the surface of the cutter shaft body 8, thereby achieving the support of the support ring 66 for the cutter shaft body 8.

[0041] The support includes a connecting platform 64, a connecting shaft 65, and a support ring 66. Two parallel connecting platforms 64 are fixedly installed on the top side of the movable seat 63. The two connecting platforms 64 are rotatably connected by the connecting shaft 65. The support ring 66 is rotatably sleeved on the surface of the connecting shaft 65 and is in close contact with the cutter shaft body 8, so that the support ring 66 can support the cutter shaft body 8 during rotation and improve the rotational stability of the cutter shaft body 8.

[0042] In this embodiment, such as Figure 6As shown, a hydraulic drive assembly is installed on the outside of the auxiliary clamping mechanism. The auxiliary clamping mechanism includes an auxiliary seat 71, a limiting rail 72, a moving rail 73, a fixed clamping plate 74, and a pressure block 75. The auxiliary seat 71 is slidably installed on the top surface of the slide rail 5, and a fastening bolt is threaded through the top side of the auxiliary seat 71. The limiting rail 72 is installed on the top of the auxiliary seat 71. The moving rail 73 is slidably connected to the inner cavity of the limiting rail 72. The top side of the moving rail 73 is fixedly connected to the fixed clamping plate 74 by bolts. The pressure block 75 is detachably installed on the inner wall of the fixed clamping plate 74. Two pressure blocks 75 are installed on the inner wall of the fixed clamping plate 74. The pressure blocks 75 are fixedly connected to the fixed clamping plate 74 by bolts. The two pressure blocks 75 form a V-shaped structure and are in contact with the side surface of the cutter shaft body 8.

[0043] The hydraulic drive assembly includes a hydraulic cylinder. In use, the auxiliary seat 71 slides along the slide rail 5 to position the cutter shaft body 8 at the location where it needs to be clamped and fixed (such as near the machining section). The auxiliary seat 71 is fixed to the slide rail 5 by fastening bolts. The hydraulic drive assembly drives the moving rail 73 to slide along the limiting rail 72, which in turn moves the fixed clamping plate 74 closer to the cutter shaft, so that the V-shaped pressure block 75 fits against the surface of the cutter shaft to achieve auxiliary clamping. The inner wall of the fixed clamping plate 74 is provided with a detachable pressure block 75, which facilitates the replacement of the pressure block 75. At the same time, the V-shaped pressure block 75 facilitates the clamping and fixing of the cutter shaft body 8.

[0044] like Figure 1 , Figures 10-12 As shown, the dustproof sleeve 9 includes multiple protective shells 91, rubber sealing gaskets 94, and connecting seats 95. The multiple protective shells 91 are nested together. A limiting groove 92 is formed on the inner wall of each protective shell 91. The limiting groove 92 is slidably connected to a limiting block fixed on the outer side of another corresponding protective shell 91. The rubber sealing gasket 94 is fixedly connected to the inner wall of the other end of each protective shell 91. The rubber sealing gasket 94 fits against the outer side of the nested protective shell 91. The rubber sealing gasket 94 fixed to the inner wall of the other end of each protective shell 91 is always tightly fitted to the outer side of the nested protective shell 91 during the expansion and contraction of the protective shell 91, forming a continuous sealing structure. This can effectively block metal shavings, coolant, and other waste generated during the processing, preventing them from falling onto the surface of the slide rail 5, avoiding the accumulation of waste that affects the sliding accuracy of the slide rail 5, and reducing the wear of impurities on the slide rail 5, thus extending the service life of the slide rail 5.

[0045] In the corresponding auxiliary support unit 6 and auxiliary clamping mechanism 7, the dust cover 9 moves and extends with the auxiliary support unit 6 and auxiliary clamping mechanism 7, covering the top side of the slide rail 5, preparing in advance to prevent waste from falling, and making it convenient to use.

[0046] like Figures 1-3As shown, two air blowing mechanisms 10 are fixedly installed on the top side surface of the processing table 1, which are symmetrically distributed about the tool axis. Each air blowing mechanism 10 includes a fixed frame 101 fixedly installed on the top side of the processing table 1, an air outlet pipe 102 installed on the surface of the fixed frame 101, and nozzles 103 evenly distributed on the side surface of the air outlet pipe 102.

[0047] During use, the waste generated during processing (such as iron filings) is blocked by the dustproof cover to prevent it from falling onto the surface of the slide rail 5 (to prevent the slide rail 5 from getting stuck); at the same time, the air blowing mechanism 10 on the processing table 1 sprays gas through the nozzle 103 of the air outlet pipe 102 to clean the waste on the surface of the cutter shaft, ensuring a clear processing view and reducing the interference of waste on the processing accuracy.

[0048] Example 2: A machining method for a tooling fixture for machining a cutter shaft part, the machining method for the tooling fixture for machining a cutter shaft part includes the following steps: 1. Based on the length, diameter, and other dimensions of the cutter shaft body 8 to be processed, pre-adjust the positions of each component on the processing table 1. Specifically, slide the movable slide 61 along the slide rail 5 to position it at the corresponding processing position of the cutter shaft body 8. Secure the movable slide 61 to the threaded hole of the slide rail 5 with fixing bolts. Then rotate the lead screw 62. Since the two movable seats 63 are connected to the lead screw 62 in opposite directions, the distance between the two movable seats 63 can be adjusted so that the support ring 66 of the support component is adapted to the diameter of the cutter shaft body 8, ensuring that the support ring 66 is in contact with the surface of the cutter shaft body 8, thereby achieving the support of the support ring 66 for the cutter shaft body 8. 2. Align one end of the cutter shaft body 8 with the clamping assembly 3, so that the center of the cutter shaft end is aligned with the positioning head 35 of the hydraulic three-jaw chuck 32; start the hydraulic three-jaw chuck 32, the jaws 33 drive the clamping blocks 34 to retract synchronously, clamping the cutter shaft end through the clamping blocks 34, rotate the lead screw 41 of the positioning mechanism 4, drive the mounting seat 42 to move the mounting seat 43 along the slide rail 5 to the other end of the cutter shaft, until the clamping head 46 on the clamping seat 45 clamps the center of the cutter shaft end; tighten the fastening bolts to fix the mounting seat 43 to the slide rail 5. Through the cooperation of the clamping assembly 3 and the positioning mechanism 4, the concentric fixation of both ends of the cutter shaft is achieved, ensuring coaxiality during processing; Third, the auxiliary seat 71 slides along the slide rail 5 to be located at the position where the cutter shaft body 8 needs to be clamped and fixed (such as near the machining section). The auxiliary seat 71 is fixed to the slide rail 5 by fastening bolts. The hydraulic drive component drives the moving rail 73 to slide along the limit rail 72, which drives the fixed clamping plate 74 to approach the cutter shaft, so that the V-shaped pressure block 75 fits against the surface of the cutter shaft to achieve auxiliary clamping. 4. The spindle 31 is connected to the machine tool motor drive end. After the motor starts, the spindle 31 drives the hydraulic three-jaw chuck 32 and the clamped cutter shaft body 8 to rotate synchronously, providing rotational power for external cylindrical machining, milling and other processes. The support ring 66 of the auxiliary support unit 6 rotates with the cutter shaft and continuously supports the middle of the cutter shaft, preventing the long cutter shaft body 8 from bending due to its own weight. The V-shaped pressure block 75 of the auxiliary clamping mechanism 7 maintains the clamping force on the cutter shaft body 8, reducing the impact of machining vibration on accuracy. 5. Waste materials generated during processing (such as iron filings) are blocked by the dustproof cover to prevent them from falling onto the surface of the slide rail 5 (to prevent the slide rail 5 from getting stuck); at the same time, the air blowing mechanism 10 on the processing table 1 sprays gas through the nozzle 103 of the air outlet pipe 102 to clean the waste materials on the processing surface of the cutter shaft body 8, ensuring a clear processing view and reducing the interference of waste materials on processing accuracy. 6. After processing is completed, release the pressure block 75 of the auxiliary clamping mechanism 7, the top clamping head 46 of the positioning mechanism 4, and the jaws 33 of the clamping component 3 in sequence, and remove the processed cutter shaft body 8; each auxiliary component can be reset along the slide rail 5, and the dustproof sleeve retracts as the components move, thus completing the processing.

9. A method for machining a tool shaft part, applied to the tooling for machining the tool shaft part according to any one of claims 1-8, characterized in that: Includes the following steps:

1. Based on the length, diameter and other dimensions of the cutter shaft body (8) to be processed, pre-adjust the position of each component on the processing table (1). Specifically, slide the movable slide (61) along the slide rail (5) to position it at the corresponding processing position of the cutter shaft body (8). Secure the movable slide (61) to the threaded hole of the slide rail (5) with the fixing bolts. Then rotate the lead screw (62). Since the two movable seats (63) are connected to the lead screw (62) in opposite directions, the distance between the two movable seats (63) can be adjusted so that the support ring (66) of the support component is adapted to the diameter of the cutter shaft body (8), ensuring that the support ring (66) is in contact with the surface of the cutter shaft body (8) and realizing the support of the support ring (66) on the cutter shaft body (8).

2. Align one end of the cutter shaft body (8) with the clamping assembly (3) so that the center of the cutter shaft end is aligned with the positioning head (35) of the center of the hydraulic three-jaw chuck (32); start the hydraulic three-jaw chuck (32), the jaws (33) drive the clamping block (34) to retract synchronously, clamp the cutter shaft end through the clamping block (34), rotate the lead screw (41) of the positioning mechanism (4), drive the mounting seat (42) to move the mounting seat (43) along the slide rail (5) to the other end of the cutter shaft until the clamping head (46) on the clamping seat (45) clamps the center of the cutter shaft end; tighten the fastening bolts to fix the mounting seat (43) to the slide rail (5), and through the cooperation of the clamping assembly (3) and the positioning mechanism (4), the two ends of the cutter shaft are concentrically fixed to ensure the coaxiality during processing; 3. The auxiliary seat (71) slides along the slide rail (5) to position the cutter shaft body (8) where it needs to be clamped and fixed. The auxiliary seat (71) is fixed to the slide rail (5) by fastening bolts. The hydraulic drive assembly drives the moving rail (73) to slide along the limit rail (72), which drives the fixed clamping plate (74) to approach the cutter shaft, so that the V-shaped pressure block (75) fits against the surface of the cutter shaft to achieve auxiliary clamping.

4. The spindle (31) is connected to the machine tool motor drive end. After the motor starts, the spindle (31) drives the hydraulic three-jaw chuck (32) and the clamped cutter shaft body (8) to rotate synchronously, providing rotational power for external cylindrical machining, milling and other processes. The support ring (66) of the auxiliary support unit (6) rotates with the cutter shaft and continuously supports the middle part of the cutter shaft, preventing the long cutter shaft body (8) from bending due to its own weight. The V-shaped pressure block (75) of the auxiliary clamping mechanism (7) maintains the clamping force on the cutter shaft body (8) and reduces the impact of machining vibration on accuracy. Fifth, the waste generated during processing is blocked by the dustproof cover to prevent it from falling onto the surface of the slide rail (5) (to prevent the slide rail (5) from getting stuck); at the same time, the air blowing mechanism (10) on the processing table (1) sprays gas through the nozzle (103) of the air outlet pipe (102) to clean the waste on the processing surface of the cutter shaft body (8), ensuring a clear processing view and reducing the interference of waste on processing accuracy; 6. After processing is completed, release the pressure block (75) of the auxiliary clamping mechanism (7), the top clamping head (46) of the positioning mechanism (4), and the jaws (33) of the clamping component (3) in sequence, and remove the processed cutter shaft body (8); each auxiliary component can be reset along the slide rail (5), and the dustproof sleeve shrinks as the components move, thus completing the processing.
