Description

Technical Field

[0001] This invention relates to the field of radial drilling machine technology, specifically to an extension rod tooling for radial drilling machines. Background Technology

[0002] In the field of radial drilling machine processing, extension rod fixtures are widely used as common auxiliary components to meet the requirements of different workpiece wall contact distances and processing ranges. However, existing radial drilling machine extension rod fixtures have significant shortcomings in practical applications: First, the length adjustment flexibility is poor. Fixed-length fixtures cannot adapt to various workpiece wall contact distances, requiring frequent changes of different specifications of fixtures. Adjustable-length fixtures, relying on fastener locking, have a cumbersome and time-consuming adjustment process, making it difficult to quickly respond to different processing conditions. Second, tool compatibility is low. The range of compatible connectors is limited. Changing to different models of drill bits or taps requires disassembling multiple parts, making the operation complex and significantly reducing processing efficiency. Third, the anti-loosening effect is poor. During high-speed operation, relying solely on thread friction or simple shims for anti-loosening is prone to causing the fixture connection to loosen due to vibration, which not only affects processing accuracy but may also lead to safety hazards such as tool detachment. Therefore, developing a tooling for extending the rod of a radial drilling machine with flexible length adjustment, high tool adaptability, and reliable anti-loosening performance has become an urgent technical problem to be solved. Summary of the Invention

[0008] Furthermore, the expanding block is a conical block, and it is adapted to the conical gap between the two elastic sheets.

[0009] Furthermore, the telescopic extension rod assembly includes a telescopic rod connected to the spindle of the radial drilling machine and an extension rod threadedly connected to the adapter head assembly. The telescopic rod has a telescopic groove inside, and the inner wall of the telescopic groove has multiple adjustment holes that extend to the outside of the telescopic rod. An elastic locking rod is installed on the side of the extension rod near the telescopic rod, and an external thread is provided on the other side of the extension rod.

[0010] Furthermore, the elastic locking rod includes a locking outer rod installed inside the extension rod, a locking spring is fixedly connected to the inner wall of the locking outer rod, and a locking inner rod is fixedly connected to the other end of the locking spring.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1 Please see Figure 1-10 This invention provides a technical solution: a tooling for extending a rod for a radial drilling machine, comprising: Telescopic extension rod assembly 2; The telescopic extension rod assembly 2 is a rod-shaped structure that can be adjusted axially. One end of it can be detachably installed on the spindle of the radial drilling machine. It is used to adjust the overall length of the tooling through axial telescopic movement to adapt to different workpiece wall-mounting distances during radial drilling machine processing, and to meet the processing range requirements under different working conditions. In actual operation, the operator first presses the locking inner rod 2043 of the elastic locking rod 204, which compresses the locking spring 2042 and retracts it into the locking outer rod 2041. Then, the operator pushes the extension rod 202 to slide along the telescopic groove of the telescopic rod 201. After adjusting to the length that adapts to the workpiece wall-mounting distance, the operator releases the locking inner rod 2043. The locking spring 2042 resets and pushes the locking inner rod 2043 into the corresponding adjustment hole 203, thus completing the length fixation. This achieves the function of flexibly adjusting the overall length of the tooling to adapt to different workpiece wall-mounting distances, thereby greatly improving the applicability and flexibility of the tooling under different processing conditions. The adapter head assembly 1 is a connection structure with multiple interface specifications. It is fixedly installed at the end of the telescopic extension rod assembly 2 away from the spindle of the radial drilling machine. It is used to detachably connect with drill bits and taps of different models and sizes through its multiple interface specifications, so as to realize the tooling's adaptability and universality to various processing tools. In use, according to the model of the drill bit or tap required for processing, select the corresponding tapered sleeve 103, insert the tapered sleeve 103 into the mounting hole 102 of the main adapter seat 101, and then lock the tapered sleeve 103 through the quick-release pin assembly 3. After the tool is installed, processing can be carried out. If the tool needs to be changed, simply operate the quick-release pin assembly 3 to remove the old tapered sleeve 103 and replace it with a new tapered sleeve 103. This achieves the function of quickly adapting to different models and sizes of drill bits and taps, thereby greatly improving the tooling's adaptability and universality to various processing tools and processing efficiency. Anti-loosening component 4 is a connecting component with anti-loosening locking function. It is nested in the connection gap between the telescopic extension rod assembly 2 and the adapter head assembly 1. It is used to prevent the relative displacement of the two due to vibration during high-speed operation of the tooling to avoid loosening at the connection. When connecting the telescopic extension rod assembly 2 and the adapter head assembly 1, the extension rod 202 is first screwed into the threaded groove 106 of the main adapter seat 101. Then, the internal thread 402 of the inner wall of the anti-loosening sleeve 401 is screwed into the external thread of the extension rod 202. At the same time, the external thread 403 on the outer surface of the anti-loosening sleeve 401 is tightened into the internal thread of the threaded groove 106. When the tooling is running at high speed, the internal thread 402 and the external thread 403 rotate in opposite directions, forming a reverse locking force. This achieves the effect of preventing the relative displacement of the telescopic extension rod assembly 2 and the adapter head assembly 1 due to vibration, thereby greatly improving the stability of the connection between the two and avoiding the risk of machining errors and tool fall-off. The positioning reference component 5 is a positioning structure with coaxiality calibration function. It is fixedly installed on the side of the telescopic extension rod assembly 2 away from the adapter head assembly 1 and is coaxial with the telescopic extension rod assembly 2. It is used to calibrate the relative position of the tooling and the workpiece during tooling processing to ensure the coaxiality of the tooling and the workpiece. When installing the tooling, the positioning boss 502 of the annular positioning disk 501 is calibrated and connected to the spindle end face of the radial drilling machine to ensure that the positioning reference component 5 and the telescopic extension rod assembly 2 are coaxial. During processing, the positioning reference component 5 continuously calibrates the relative position of the tooling and the workpiece, thereby achieving the function of real-time calibration of the relative position of the tooling and the workpiece, which greatly improves the coaxiality of the tooling and the workpiece and ensures the accuracy of the machined hole positions. Furthermore, the adapter assembly 1 includes a main adapter base 101 and a tapered sleeve 103. The outer surface of the tapered sleeve 103 has an annular positioning groove 104. The main adapter base 101 has mounting holes 102 and threaded grooves 106 on its two sides, respectively. The inner wall of the mounting hole 102 has a quick-release pin hole 105, and a quick-release pin rod assembly 3 is disposed inside the quick-release pin hole 105. The threaded groove 106 has an internal thread. When installing the tapered sleeve 103, it is inserted into the mounting hole 102, so that the annular positioning groove 104... Align the shaped positioning groove 104 with the quick-release pin hole 105, then insert the pin 301 of the quick-release pin rod assembly 3 into the quick-release pin hole 105, and lock the tapered sleeve 103 by locking the snap block 302 into the annular positioning groove 104. When connecting the telescopic extension rod assembly 2, screw the extension rod 202 into the internal thread of the threaded groove 106, thereby achieving the function of stable installation of the tapered sleeve 103 and reliable connection of the telescopic extension rod assembly 2, which greatly improves the connection stability and reliability of the adapter head assembly 1. Furthermore, the quick-release pin assembly 3 includes a pin 301 installed inside the quick-release pin hole 105 and slots 303 formed on both sides of the inner wall of the quick-release pin hole 105. Positioning holes 307 are formed on both sides of the pin 301, and a fixing plate 305 is fixedly connected inside the pin 301. Elastic plates 306 are installed on both sides of the bottom of the fixing plate 305. A locking block 302 is fixedly connected to the other end of the elastic plate 306. The end of the locking block 302 away from the elastic plate 306 extends into the slot 303 through the positioning hole 307. Before installing the pin 301, first... Pulling the pull plate 304 moves the pull rod 308 and the spreading block 309, causing the spreading block 309 to disengage from the elastic piece 306. The elastic piece 306 rebounds, causing the locking block 302 to retract into the positioning hole 307. After inserting the pin 301 into the quick-release pin hole 105, the pull plate 304 is released. The return spring 310 pushes the spreading block 309 to squeeze the elastic piece 306, causing the locking block 302 to pass through the positioning hole 307 and lock into the slot 303. This achieves the function of quickly locking the pin 301 to fix the tapered sleeve 103, thereby greatly improving the installation efficiency and fixing stability of the tapered sleeve 103. Furthermore, a pull rod 308 is slidably connected inside the pin 301. One end of the pull rod 308 extends to the outside of the pin 301 and is fixedly connected to a pull plate 304. The other end of the pull rod 308 extends between two elastic plates 306 and is fixedly connected to a spreading block 309. A return spring 310 is sleeved on the outer surface of the pull rod 308 between the inner wall of the pin 301 and the spreading block 309. When it is necessary to disassemble the tapered sleeve 103, the pull plate 304 is pulled, and the pull rod 308 drives the spreading block 309. When 09 moves outward, the return spring 310 is compressed, the expansion block 309 disengages from the elastic plate 306, and the elastic plate 306 rebounds, causing the locking block 302 to disengage from the slot 303. The pin 301 can then be pulled out and the tapered sleeve 103 removed. During installation, the pull plate 304 is released, and the return spring 310 pushes the expansion block 309 to reset and compress the elastic plate 306 to achieve locking. This achieves the function of quickly disassembling and assembling the pin 301 to replace the tapered sleeve 103, thereby greatly improving the convenience and efficiency of tool replacement. Furthermore, the expansion block 309 is a conical block, which is adapted to the conical gap between the two elastic plates 306. When the return spring 310 pushes the expansion block 309 to move, the conical expansion block 309 can be precisely embedded into the conical gap between the two elastic plates 306. As the expansion block 309 goes deeper, it gradually squeezes the elastic plates 306 to unfold to both sides, so that the locking block 302 extends stably out of the positioning hole 307. This achieves the function of accurately and stably squeezing the elastic plates 306 to realize the reliable locking of the locking block 302, thereby greatly improving the stability and reliability of the locking of the quick-release pin assembly 3. Furthermore, the telescopic extension rod assembly 2 includes a telescopic rod 201 connected to the spindle of the radial drilling machine and an extension rod 202 threadedly connected to the adapter assembly 1. The telescopic rod 201 has a telescopic groove inside, and the inner wall of the telescopic groove has multiple adjustment holes 203 extending to the outside of the telescopic rod 201. An elastic locking rod 204 is installed on the side of the extension rod 202 near the telescopic rod 201, and an external thread is provided on the other side of the extension rod 202. When adjusting the length, press the locking inner rod 2043 of the elastic locking rod 204 to retract it, push the extension rod 202 to slide in the telescopic groove, select the appropriate adjustment hole 203 according to the distance of the workpiece against the wall, release the locking inner rod 2043 to make it lock into the adjustment hole 203, and when connecting the adapter assembly 1, screw the external thread of the extension rod 202 into the thread groove 106, thereby achieving the function of flexibly adjusting the tooling length and stably connecting the adapter assembly 1, thus greatly improving the adaptability and connection reliability of the tooling. Furthermore, the elastic locking rod 204 includes a locking outer rod 2041 installed inside the extension rod 202. A locking spring 2042 is fixedly connected to the inner wall of the locking outer rod 2041. A locking inner rod 2043 is fixedly connected to the other end of the locking spring 2042. The end of the locking inner rod 2043 away from the locking spring 2042 extends into the adjustment hole 203. When adjusting the length of the telescopic extension rod assembly 2, pressing the locking inner rod 2043 compresses the locking spring 2042, and the locking inner rod 2043 retracts to the locking outer rod 2041, facilitating the sliding of the extension rod 202. After adjustment, the locking spring 2042 resets and pushes the locking inner rod 2043 into the adjustment hole 203 to fix the length, thereby achieving the function of quickly locking and unlocking the position of the extension rod 202, and thus greatly improving the convenience and efficiency of length adjustment of the telescopic extension rod assembly 2. Furthermore, the anti-loosening component 4 includes an anti-loosening sleeve 401. The inner wall of the anti-loosening sleeve 401 has an internal thread 402, and the outer surface of the anti-loosening sleeve 401 has an external thread 403. When connecting the telescopic extension rod assembly 2 and the adapter assembly 1, the extension rod 202 is first screwed into the threaded groove 106, and then the internal thread 402 of the anti-loosening sleeve 401 is screwed into the external thread of the extension rod 202. At the same time, the external thread 403 is tightened into the internal thread of the threaded groove 106. When the tooling is running, the reverse-rotating threads form a reverse locking force, thereby preventing the connection between the two from loosening, and thus greatly improving the connection stability when the tooling is running at high speed. Furthermore, the internal thread inside the threaded groove 106 is adapted to the external thread 403, and the external thread on the outer surface of the extension rod 202 is adapted to the internal thread 402, with the internal thread 402 and the external thread 403 having opposite thread directions. When the anti-loosening sleeve 401 is installed, the internal thread 402 and the external thread of the extension rod 202, and the external thread 403 and the internal thread of the threaded groove 106 can be precisely screwed together. When the tooling vibrates during high-speed operation, the reverse-rotating threads prevent the anti-loosening sleeve 401 from loosening and instead produce a tighter locking effect, thereby enhancing the anti-loosening effect and greatly improving the long-term stability of the connection between the telescopic extension rod assembly 2 and the adapter head assembly 1. Furthermore, the positioning reference assembly 5 includes an annular positioning disk 501 installed at the end of the telescopic rod 201 away from the extension rod 202, and a positioning boss 502 is fixedly connected to the other end of the annular positioning disk 501. When installing the tooling, the positioning boss 502 is aligned and calibrated with the end face of the radial drilling machine spindle to ensure that the annular positioning disk 501 and the telescopic rod 201 are coaxial. During the machining process, the annular positioning disk 501 continuously serves as a reference to calibrate the relative position of the tooling and the workpiece, thereby ensuring the coaxiality of the tooling and the workpiece, and thus greatly improving the accuracy and consistency of the machined hole positions.

[0019] Example 2 An extension rod fixture for a radial drilling machine includes: Telescopic extension rod assembly 2; The telescopic extension rod assembly 2 is a rod-shaped structure that can be adjusted axially. One end of it can be detachably installed on the spindle of the radial drilling machine. It is used to adjust the overall length of the tooling through axial telescopic movement to adapt to different workpiece wall-mounting distances during radial drilling machine processing, and to meet the processing range requirements under different working conditions. In actual operation, the operator first presses the locking inner rod 2043 of the elastic locking rod 204, which compresses the locking spring 2042 and retracts it into the locking outer rod 2041. Then, the operator pushes the extension rod 202 to slide along the telescopic groove of the telescopic rod 201. After adjusting to the length that adapts to the workpiece wall-mounting distance, the operator releases the locking inner rod 2043. The locking spring 2042 resets and pushes the locking inner rod 2043 into the corresponding adjustment hole 203, thus completing the length fixation. This achieves the function of flexibly adjusting the overall length of the tooling to adapt to different workpiece wall-mounting distances, thereby greatly improving the applicability and flexibility of the tooling under different processing conditions. The adapter head assembly 1 is a connection structure with multiple interface specifications. It is fixedly installed at the end of the telescopic extension rod assembly 2 away from the spindle of the radial drilling machine. It is used to detachably connect with drill bits and taps of different models and sizes through its multiple interface specifications, so as to realize the tooling's adaptability and universality to various processing tools. In use, according to the model of the drill bit or tap required for processing, select the corresponding tapered sleeve 103, insert the tapered sleeve 103 into the mounting hole 102 of the main adapter seat 101, and then lock the tapered sleeve 103 through the quick-release pin assembly 3. After the tool is installed, processing can be carried out. If the tool needs to be changed, simply operate the quick-release pin assembly 3 to remove the old tapered sleeve 103 and replace it with a new tapered sleeve 103. This achieves the function of quickly adapting to different models and sizes of drill bits and taps, thereby greatly improving the tooling's adaptability and universality to various processing tools and processing efficiency. The positioning reference component 5 is a positioning structure with coaxiality calibration function. It is fixedly installed on the side of the telescopic extension rod assembly 2 away from the adapter head assembly 1 and is coaxial with the telescopic extension rod assembly 2. It is used to calibrate the relative position of the tooling and the workpiece during tooling processing to ensure the coaxiality of the tooling and the workpiece. When installing the tooling, the positioning boss 502 of the annular positioning disk 501 is calibrated and connected to the spindle end face of the radial drilling machine to ensure that the positioning reference component 5 and the telescopic extension rod assembly 2 are coaxial. During processing, the positioning reference component 5 continuously calibrates the relative position of the tooling and the workpiece, thereby achieving the function of real-time calibration of the relative position of the tooling and the workpiece, which greatly improves the coaxiality of the tooling and the workpiece and ensures the accuracy of the machined hole positions. Furthermore, the adapter assembly 1 includes a main adapter base 101 and a tapered sleeve 103. The outer surface of the tapered sleeve 103 has an annular positioning groove 104. The main adapter base 101 has mounting holes 102 and threaded grooves 106 on its two sides, respectively. The inner wall of the mounting hole 102 has a quick-release pin hole 105, and a quick-release pin rod assembly 3 is disposed inside the quick-release pin hole 105. The threaded groove 106 has an internal thread. When installing the tapered sleeve 103, it is inserted into the mounting hole 102, so that the annular positioning groove 104 aligns with the tapered sleeve 103. Align the quick-release pin holes 105, then insert the pin body 301 of the quick-release pin rod assembly 3 into the quick-release pin holes 105, and lock the tapered sleeve 103 by engaging the snap block 302 into the annular positioning groove 104. When connecting the telescopic extension rod assembly 2, directly tighten the extension rod 202 and the internal thread of the threaded groove 106 to the preset torque, thereby achieving the function of stable installation of the tapered sleeve 103 and reliable connection of the telescopic extension rod assembly 2, which greatly improves the connection stability and assembly convenience of the adapter assembly 1 in the absence of anti-loosening components. Furthermore, the quick-release pin assembly 3 includes a pin 301 installed inside the quick-release pin hole 105 and slots 303 formed on both sides of the inner wall of the quick-release pin hole 105. Positioning holes 307 are formed on both sides of the pin 301, and a fixing plate 305 is fixedly connected inside the pin 301. Elastic plates 306 are installed on both sides of the bottom of the fixing plate 305. A locking block 302 is fixedly connected to the other end of the elastic plate 306. The end of the locking block 302 away from the elastic plate 306 extends into the slot 303 through the positioning hole 307. Before installing the pin 301, the pull plate 304 is pulled to drive the pull... The rod 308 and the spreading block 309 move, causing the spreading block 309 to disengage from the elastic plate 306. The elastic plate 306 rebounds, causing the locking block 302 to retract into the positioning hole 307. After the pin 301 is inserted into the quick-release pin hole 105, the pull plate 304 is released. The return spring 310 pushes the spreading block 309 to squeeze the elastic plate 306, causing the locking block 302 to pass through the positioning hole 307 and lock into the slot 303. This achieves the function of quickly locking the pin 301 to fix the tapered sleeve 103, thereby greatly improving the installation efficiency and fixing stability of the tapered sleeve 103 and making up for the reliability requirements of tool connection when there is no anti-loosening component. Furthermore, a pull rod 308 is slidably connected inside the pin 301. One end of the pull rod 308 extends to the outside of the pin 301 and is fixedly connected to a pull plate 304. The other end of the pull rod 308 extends between two elastic plates 306 and is fixedly connected to a spreading block 309. A return spring 310 is sleeved on the outer surface of the pull rod 308 located between the inner wall of the pin 301 and the spreading block 309. When it is necessary to disassemble the cone sleeve 103, the pull plate 304 is pulled, and the pull rod 308 drives the spreading block 309 to move outward, thus resetting the pin. When the spring 310 is compressed, the expansion block 309 disengages from the elastic plate 306. The elastic plate 306 rebounds, causing the locking block 302 to disengage from the slot 303. The pin 301 can then be pulled out to remove the tapered sleeve 103. During installation, the pull plate 304 is released, and the return spring 310 pushes the expansion block 309 to reset and compress the elastic plate 306 to achieve locking. This achieves the function of quickly disassembling and assembling the pin 301 to replace the tapered sleeve 103, thereby greatly improving the convenience and efficiency of tool replacement and meeting the need to simplify the assembly process when there are no anti-loosening components. Furthermore, the expansion block 309 is a conical block, which is adapted to the conical gap between the two elastic plates 306. When the return spring 310 pushes the expansion block 309 to move, the conical expansion block 309 can be precisely embedded into the conical gap between the two elastic plates 306. As the expansion block 309 goes deeper, it gradually squeezes the elastic plates 306 to unfold to both sides, so that the locking block 302 is stably extended out of the positioning hole 307. This achieves the function of accurately and stably squeezing the elastic plates 306 to realize the reliable locking of the locking block 302, thereby greatly improving the stability and reliability of the locking of the quick-release pin assembly 3 and ensuring the tightness of the tool connection when there is no anti-loosening component. Furthermore, the telescopic extension rod assembly 2 includes a telescopic rod 201 connected to the spindle of the radial drilling machine and an extension rod 202 threadedly connected to the adapter assembly 1. The telescopic rod 201 has a telescopic groove inside, and the inner wall of the telescopic groove has multiple adjustment holes 203 extending to the outside of the telescopic rod 201. An elastic locking rod 204 is installed on the side of the extension rod 202 near the telescopic rod 201, and an external thread is provided on the other side of the extension rod 202. When adjusting the length, press the locking inner rod 2043 of the elastic locking rod 204 to retract it, push the extension rod 202 to slide in the telescopic groove, select the appropriate adjustment hole 203 according to the distance of the workpiece against the wall, and release the locking inner rod 2043 to make it lock into the adjustment hole 203. When connecting the adapter assembly 1, tighten the external thread of the extension rod 202 with the thread groove 106 without additional anti-loosening operation, thereby achieving the function of flexibly adjusting the tooling length and stably connecting the adapter assembly 1, and thus greatly improving the adaptability and assembly efficiency of the tooling in the absence of anti-loosening components. Furthermore, the elastic locking rod 204 includes a locking outer rod 2041 installed inside the extension rod 202. A locking spring 2042 is fixedly connected to the inner wall of the locking outer rod 2041. A locking inner rod 2043 is fixedly connected to the other end of the locking spring 2042. The end of the locking inner rod 2043 away from the locking spring 2042 extends into the adjustment hole 203. When adjusting the length of the telescopic extension rod assembly 2, pressing the locking inner rod 2043 compresses the locking spring 2042, and the locking inner rod 2043 retracts to the locking outer rod 2041, facilitating the sliding of the extension rod 202. After adjustment, the locking spring 2042 resets and pushes the locking inner rod 2043 into the adjustment hole 203 to fix the length. This achieves the function of quickly locking and unlocking the position of the extension rod 202, thereby greatly improving the convenience and efficiency of length adjustment of the telescopic extension rod assembly 2 and ensuring the reliability of tooling length adjustment when there is no anti-loosening component. Furthermore, the internal thread inside the threaded groove 106 is compatible with the external thread on the outer surface of the extension rod 202, and both adopt a fine thread design to improve self-locking performance. When connecting the extension rod 202 and the main adapter 101, the tight fit of the fine thread can enhance the friction between the threads, reduce the risk of loosening caused by vibration, and maintain stable connection in low-to-medium speed processing scenarios without additional anti-loosening components. This achieves the effect of improving the self-locking performance of the threaded connection, thereby greatly improving the connection stability between the telescopic extension rod assembly 2 and the adapter head assembly 1, and adapting to low-to-medium speed processing requirements. Furthermore, the positioning reference assembly 5 includes an annular positioning disk 501 installed at the end of the telescopic rod 201 away from the extension rod 202, and a positioning boss 502 fixedly connected to the other end of the annular positioning disk 501. When installing the tooling, the positioning boss 502 is aligned and calibrated with the spindle end face of the radial drilling machine to ensure that the annular positioning disk 501 and the telescopic rod 201 are coaxial. During the machining process, the annular positioning disk 501 continuously serves as a reference to calibrate the relative position of the tooling and the workpiece, thereby ensuring the coaxiality of the tooling and the workpiece. This greatly improves the accuracy and consistency of the machined hole positions and compensates for the impact of slight vibrations that may occur due to the lack of anti-loosening components on the machining accuracy. Working Principle: In scenarios where radial drilling machines are used for deep hole machining or wall-mounted hole machining on large workpieces, when the workpiece's wall-mounted distance exceeds the machining range of the radial drilling machine spindle, or when different types of drill bits and taps need to be changed to complete the combined drilling and tapping machining, this extension rod fixture can achieve precise adaptation to machining requirements. First, the operator needs to align and calibrate the positioning boss 502 of the annular positioning disk 501 in the positioning reference assembly 5 with the end face of the radial drilling machine spindle, ensuring that the positioning reference assembly 5 and the telescopic extension rod assembly 2 are strictly coaxial. This allows for advance calibration of the relative position of the fixture and the workpiece, effectively avoiding hole position offset problems caused by coaxiality deviations during subsequent machining, thus laying the foundation for machining accuracy. After the positioning reference component 5 is installed, the length of the telescopic extension rod component 2 can be adjusted according to actual needs. During adjustment, the operator first presses the locking inner rod 2043 extending to the outside of the adjustment hole 203 in the elastic locking rod 204, so that the locking inner rod 2043 compresses the locking spring 2042 and retracts into the locking outer rod 2041. At this time, the extension rod 202 can be pushed to slide axially along the telescopic groove inside the telescopic rod 201. After adjusting to the length that matches the distance between the workpiece and the wall, the locking spring 2042 resets and pushes the locking inner rod 2043 to be inserted into the corresponding adjustment hole 203 again, thereby fixing the length of the telescopic extension rod component 2. This adjustment method does not require additional tools, and the setting of multiple adjustment holes 203 can meet the processing range requirements under different working conditions, greatly improving the applicability of the tooling. Then, the adapter head assembly 1 and the telescopic extension rod assembly 2 are connected. During the connection, the threaded end of the extension rod 202 is first screwed into the threaded groove 106 of the main adapter seat 101. At the same time, the anti-loosening sleeve 401 of the anti-loosening assembly 4 is screwed into the external thread of the extension rod 202 through the internal thread 402 on the inner wall. The external thread 403 on the outer surface of the anti-loosening sleeve 401 is further tightened into the internal thread of the threaded groove 106. Since the internal thread 402 and the external thread 403 have opposite threads, when the tooling vibrates at high speed, the two will form a reverse locking force, which effectively prevents relative displacement at the connection gap between the telescopic extension rod assembly 2 and the adapter head assembly 1, and avoids the risk of machining errors or tool falling off due to loosening at the connection.

[0020] Next, install the corresponding tapered sleeve 103 according to the processing requirements. During installation, the operator first inserts the tapered sleeve 103 into the mounting hole 102 of the main adapter seat 101, and then pulls the pull plate 304 of the quick-release pin assembly 3. The pull plate 304 drives the pull rod 308 and the expansion block 309 connected to the pull rod 308 to move outward of the pin body 301, so that the expansion block 309 disengages from the two elastic plates 306. At this time, on the one hand, the elastic plates 306 rebound under their own elasticity, causing the locking block 302 to retract into the positioning hole 307. On the other hand, during the movement of the pull rod 308, the return spring 310 located between the inner wall of the pin body 301 and the expansion block 309 will be compressed. Then, the pin body 301 is inserted into the quick-release pin hole 105, and it is ensured that the pin body 301 is in contact with the outer surface of the tapered sleeve 103. The annular positioning groove 104 on the surface corresponds to the position of the pin 301. After the pin 301 is installed in place, the pulling force of the pull plate 304 is released. The return spring 310 pushes the expansion block 309 to reset under the elastic action, so that it is reinserted between the two elastic plates 306. The tapered expansion block 309 will squeeze the elastic plate 306, thereby quickly pushing the locking block 302 out of the positioning hole 307 and locking it into the slot 303, completing the quick installation of the tapered sleeve 103. If the tool needs to be replaced, simply pull the pull plate 304 again and repeat the above operation to remove the tapered sleeve 103. This means that the device does not need to remove the screws, greatly shortening the tool replacement time. Moreover, the tapered sleeve 103 with multiple interface specifications can be adapted to different models and sizes of drill bits and taps, thereby greatly improving the adaptability and versatility of this tooling to various processing tools.
