Description

Technical Field

[0001] This invention belongs to the field of tool mounting technology, specifically a tool mounting and fixing structure for CNC lathes. Background Technology

[0002] CNC lathe is short for numerical control lathe. It is an automated lathe equipped with a program control system. The machine tool has a wide range of machining capabilities and can process complex workpieces such as straight cylinders, inclined cylinders, arcs, and various threads, grooves, and worm gears. It has various compensation functions such as linear interpolation and circular interpolation, and has played a good economic role in the mass production of complex parts. When using a CNC lathe to process a workpiece, a tool setting operation is required first, which is to install and fix the tool to be used on the CNC lathe.

[0003] A patent with publication number CN114799243B discloses a tool mounting and fixing structure for CNC lathes. This patent involves inserting a mounting block into a connecting block and having a baffle contact the right side wall of the connecting block. Rotating a knob drives a transmission rod, which in turn rotates the driving bevel gear on the outer circumference of the transmission rod. The rotation of the driving bevel gear causes a driven bevel gear meshing with it to rotate through a connecting tube on the inner side wall of the mounting block. The rotation of the driven bevel gear causes a screw to rotate through the key block and keyway. Because the screw is threaded to the side wall of the mounting block, it moves outward during rotation, pushing a top block into the connecting groove to fix the connecting block to the mounting block, thus completing the installation of the CNC lathe tool. This significantly improves the tool mounting and fixing speed without the need for tools.

[0004] The above solution still has some problems in practical application. It usually uses bolts and limiting washers to limit and fix the tool on the tool holder. When adjusting the position of the tool, the bolts must be loosened and the tool moved around repeatedly. This is not only time-consuming and laborious, but also requires a certain preload when the bolts are tightened for the first time to ensure the fixing effect. This makes it more difficult for the operator to loosen the bolts with a screwdriver every time. In addition, when the tool is turning the workpiece, water is usually sprayed to cool the tool, which can cause the bolts to rust. This further increases the difficulty of removing the tool by turning the bolts when changing the tool later.

[0005] Therefore, the present invention provides a tool mounting and fixing structure for CNC lathes. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a tool mounting and fixing structure for a CNC lathe, comprising a CNC machine tool body, a tool mounting holder provided on the inner wall of the CNC machine tool body, and a tool mounting and fixing assembly installed on the upper end of the tool mounting holder; Furthermore, the tool mounting and fixing assembly includes a tool fixing cylinder mounted on the upper end of the tool mounting holder. Four limiting rods are symmetrically fixed to the inner wall of the tool fixing cylinder. A mounting block is slidably arranged in the inner cavity of the tool fixing cylinder. A mounting groove is opened inside one side of the mounting block, and the tool body is installed in the inner cavity of the mounting groove. The upper part of the CNC machine tool body is equipped with a protective shell, and a protective cabinet door is slidably connected to the front end of the protective shell. An observation window is opened inside the protective cabinet door for observing the internal operation of the CNC machine tool body.

[0008] Preferably, two guide blocks are symmetrically installed on one side of the inner cavity of the mounting groove. A fixing rod is fixedly connected to one end of the cutter body, and a stop block is fixedly connected to one end of the fixing rod. The guide blocks are used to guide the stop block to slide into the inner cavity of the mounting groove for installation.

[0009] Preferably, a rotating groove is provided inside one end of the mounting block, and a threaded sleeve is rotatably connected to the inner cavity of the rotating groove. A knob is fixedly connected to one end of the threaded sleeve through the mounting block, and a threaded telescopic rod is threadedly connected to the inner cavity of the threaded sleeve. A push plate is rotatably connected to one end of the threaded telescopic rod through the mounting block and located in the inner cavity of the mounting groove, which is used to push the abutment block to adjust the position of the tool body.

[0010] Preferably, the fixing rod has multiple slots evenly distributed on its outer surface, and the guide block is inserted and engaged with the slots.

[0011] Preferably, a transmission bevel gear is fixedly connected to the outside of the threaded sleeve, and the transmission bevel gear is meshed with a driven bevel gear. A U-shaped fixing block is fixedly connected to the inside of one end of the driven bevel gear, and a ratchet block is provided in the inner cavity of the U-shaped fixing block.

[0012] Preferably, the mounting block has grooves on both sides, and a gear is rotatably connected to the inner cavity of the groove. A cylinder is fixed to one end of the gear, and a ratchet is fixed to the outside of the cylinder. The ratchet locking block is inserted and engaged with the ratchet.

[0013] Preferably, a rack is installed on the upper end face of the limiting rod, and the rack is meshed with a gear. Two triangular fixing blocks are symmetrically fixed to one side of the inner cavity of the tool fixing cylinder, and the two triangular fixing blocks are used to abut against the mounting block for installation.

[0014] Preferably, a solid-liquid separation drawer is slidably provided on the lower part of the front end face of the CNC machine tool body. A filter screen is installed in the inner cavity of the solid-liquid separation drawer, and a liquid recovery port is provided at the bottom of the inner cavity of the solid-liquid separation drawer for liquid recycling and reuse.

[0015] Preferably, one end of the mounting block is triangular and is used to insert into the inner cavity of the tool fixing cylinder. The surface of the mounting block abuts against the triangular fixing block to compress the mounting block to hold the fixing rod.

[0016] Preferably, a triangular chuck is installed on one side of the inner cavity of the CNC machine tool body, and a control console is provided on one side of the front end face of the protective shell.

[0017] The beneficial effects of this invention are as follows: 1. The present invention provides a tool mounting and fixing structure for CNC lathes. By holding the fixing rod and inserting a stop block into the mounting groove, the stop block slides against the surface of the guide block, thereby pushing the mounting block to expand. After the stop block slides into the inner cavity of the mounting groove, the mounting block drives the guide block to spring back and reset, thus limiting the stop block. Then, the mounting block is inserted into the inner cavity of the tool fixing cylinder. At the same time, the mounting block pushes the guide block to compress and fix the fixing rod, thereby ensuring the stability of the tool body. This solves the problem that existing tool mounting and fixing structures for CNC lathes usually use bolts and limiting washers to limit and fix the tool to the tool holder. This results in the need to loosen the bolts with external screwdrivers or other workpieces to replace the tool each time the tool is installed or removed. Moreover, when the tool is used to turn the workpiece, water is sprayed to cool the tool, which can cause the bolts to rust, making it more difficult to turn the bolts with a screwdriver and making tool replacement more time-consuming and laborious.

[0018] 2. The tool mounting and fixing structure for CNC lathes described in this invention involves inserting a mounting block into the inner cavity of the tool fixing cylinder. Simultaneously, a triangular fixing block presses the mounting block, pushing a guide block into a slot outside the fixing rod, further engaging the fixing rod to ensure the stability of the tool body. When the mounting block needs to be removed, a driven bevel gear drives the U-shaped fixing block to rotate, simultaneously engaging a ratchet block inside the U-shaped fixing block with the ratchet. This causes the gear to mesh and rotate outside the rack, ultimately removing the mounting block from the inner cavity of the tool fixing cylinder. This solves the problem of existing CNC lathe tool mounting structures... When installing and fixing cutting tools, bolts and limiting washers are usually used to limit and fix the tool to the tool holder. The bolts need to reach a certain preload when tightened for the first time to ensure the fixing effect. However, during long-term operation, due to factors such as vibration and temperature changes, the preload will gradually decrease, causing the tool to loosen. Moreover, if the tool needs to be replaced frequently, the preload will make it more difficult for the operator to loosen the bolts and make tool replacement more time-consuming and laborious.

[0019] 3. The tool mounting and fixing structure for CNC lathes described in this invention drives a threaded sleeve to rotate by turning a knob. Simultaneously, the threaded sleeve drives a threaded telescopic rod to rotate, which in turn causes the telescopic rod to slide inside the mounting block. This causes the telescopic rod to drive a push plate to slide in the inner cavity of the mounting groove, thereby causing the push plate to abut against the stop block. The push plate then pushes the stop block, causing a fixing rod to move into the inner cavity of the tool fixing cylinder. At the same time, the fixing rod causes the tool body to slide out of the tool fixing cylinder for position adjustment. This solves the problem that existing tool mounting and fixing structures for CNC lathes require loosening bolts and then adjusting the tool body's position on the tool holder after installation, which is cumbersome, time-consuming, and labor-intensive.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1

[0023] like Figures 1 to 8 As shown in the figure, a tool mounting and fixing structure for a CNC lathe according to an embodiment of the present invention includes a CNC machine tool body 1, a tool mounting holder 4 is provided on the inner wall of the CNC machine tool body 1, and a tool mounting and fixing assembly 8 is installed on the upper end of the tool mounting holder 4; Furthermore, the tool mounting and fixing assembly 8 includes a tool fixing cylinder 81 mounted on the upper end of the tool mounting holder 4. Four limiting rods 82 are symmetrically fixed to the inner wall of the tool fixing cylinder 81. A mounting block 10 is slidably arranged in the inner cavity of the tool fixing cylinder 81. A mounting groove 12 is opened inside one side of the mounting block 10. The tool body 11 is installed in the inner cavity of the mounting groove 12. A protective shell 2 is installed on the upper part of the CNC machine tool body 1. A protective cabinet door 3 is slidably connected to the front end of the protective shell 2, and an observation window is opened inside the protective cabinet door 3 for observing the internal operation of the CNC machine tool body 1.

[0024] Specifically, in existing technologies, bolts and limiting washers are typically used to limit and fix the cutting tool to the tool holder. When the bolts are tightened for the first time, a certain preload is required to ensure the fixing effect. However, during long-term operation, due to factors such as the high temperature and vibration generated by the cutting tool and the workpiece, the preload of the bolts will gradually decrease, causing the cutting tool to loosen. If water is sprayed to cool the cutting tool when it is cutting the workpiece, it will cause the bolts to rust, which will increase the difficulty of removing the cutting tool by turning the bolts when replacing the tool later. In this invention, when installing a cutting tool, the tool retaining sleeve 81 is inserted into the tool mounting holder 4 and secured. Then, the tool body 11 is inserted into the mounting groove 12 inside the mounting block 10, while the mounting block 10 is inserted into the tool retaining sleeve 81, with the cutting tip of the tool body 11 protruding from the other end of the inner cavity of the tool retaining sleeve 81. In this way, the tool retaining sleeve 81 protects the tool body 11 and simultaneously secures the mounting block 10. The mounting block 10 is then inserted into the tool retaining sleeve... Inside the cavity of 81, the tool fixing cylinder 81 can also press the mounting block 10, causing the mounting block 10 to press the tool body 11 in the cavity of the mounting groove 12, thereby fixing the tool body 11 in the cavity of the mounting groove 12. This prevents the tool body 11 from shaking when cutting the workpiece. Moreover, when disassembling and replacing the tool body 11, the mounting block 10 can be removed from the cavity of the tool fixing cylinder 81, allowing for quick disassembly and replacement of the tool body 11, thus solving the above problems.

[0025] like Figure 4 , Figure 5 and Figure 6 As shown, two guide blocks 13 are symmetrically installed on one side of the inner cavity of the mounting groove 12. A fixing rod 22 is fixedly connected to one end of the tool body 11, and a stop block 23 is fixedly connected to one end of the fixing rod 22. The guide block 13 is used to guide the stop block 23 to slide into the inner cavity of the mounting groove 12 for installation.

[0026] Specifically, when installing the tool body 11, the fixing rod 22 is held and the abutment 23 is inserted into the mounting groove 12, and the abutment 23 slides against the surfaces of the two guide blocks 13. The abutment 23, in conjunction with the two guide blocks 13, pushes the mounting block 10 to expand. After the abutment 23 slides into the inner cavity of the mounting groove 12, the mounting block 10 causes the guide blocks 13 to spring back to their original position, thereby limiting the abutment 23. Then, the mounting block 10 is inserted into the inner cavity of the tool fixing cylinder 81, and the tool fixing cylinder 81 presses against the mounting block 10, while the mounting block 10 pushes the guide blocks. 13. The fixing rod 22 is pressed and fixed to ensure the stability of the tool body 11. This solves the problem that the existing tool installation and fixing structure of CNC lathes usually uses bolts and limiting washers to limit and fix the tool on the tool holder. This means that every time the tool is installed or removed, it is necessary to use an external screwdriver or other workpiece to loosen the bolts to replace the tool. Moreover, when the tool is used to turn the workpiece, water is sprayed to cool the tool, which can cause the bolts to rust. This makes it more difficult to turn the bolts with a screwdriver and makes it more time-consuming and laborious to replace the tool.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, a rotating groove 21 is provided inside one end of the mounting block 10. A threaded sleeve 16 is rotatably connected to the inner cavity of the rotating groove 21. A knob 9 is fixed to one end of the threaded sleeve 16 through the mounting block 10. A threaded telescopic rod 15 is threadedly connected to the inner cavity of the threaded sleeve 16. A push plate 14 is rotatably connected to one end of the threaded telescopic rod 15 through the mounting block 10 and located in the inner cavity of the mounting groove 12. This push plate 14 is used to push the stop block 23 to adjust the position of the tool body 11.

[0028] Specifically, when the length of the tool body 11 needs to be adjusted, the threaded sleeve 16 is driven to rotate by turning the knob 9. At the same time, the threaded sleeve 16 drives the threaded telescopic rod 15 to rotate, which in turn causes the threaded telescopic rod 15 to slide inside the mounting block 10. This causes the threaded telescopic rod 15 to drive the push plate 14 to slide in the inner cavity of the mounting groove 12, thereby causing the push plate 14 to abut against the stop block 23. Then, the push plate 14 pushes the stop block 23 to move the fixing rod 22 into the inner cavity of the tool fixing cylinder 81. At the same time, the fixing rod 22 causes the tool body 11 to slide out of the tool fixing cylinder 81 for position adjustment. This solves the problem that in the existing tool mounting and fixing structure of CNC lathes, after the tool is installed and fixed, if the position of the tool needs to be adjusted, the bolts need to be loosened and the tool body needs to be adjusted to adjust its position on the tool holder, which is cumbersome, time-consuming and labor-intensive.

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, multiple slots are evenly distributed on the outside of the fixing rod 22, and the guide block 13 is inserted and engaged with the slots.

[0030] like Figure 4 , Figure 5 and Figure 8 As shown, a transmission bevel gear 20 is fixedly connected to the outside of the threaded sleeve 16. The transmission bevel gear 20 is meshed with a driven bevel gear 17. A U-shaped fixing block 18 is fixedly connected to the inside of one end of the driven bevel gear 17. A ratchet block is provided in the inner cavity of the U-shaped fixing block 18.

[0031] like Figure 4 , Figure 6 and Figure 8 As shown, the mounting block 10 has grooves 25 on both sides. A gear 24 is rotatably connected to the inner cavity of the groove 25. A cylinder 19 is fixed to one end of the gear 24. A ratchet 26 is fixed to the outside of the cylinder 19. The ratchet block is inserted and engaged with the ratchet 26.

[0032] Specifically, when installing the tool body 11, the mounting block 10 is inserted into the inner cavity of the tool fixing cylinder 81. Simultaneously, the mounting block 10 slides outside the limiting rod 82 via the groove 25, and the limiting rod 82 limits and stabilizes the mounting block 10. At the same time, the mounting block 10 drives the gear 24 to mesh with the rack 83, pushing the mounting block 10 into the inner cavity of the tool fixing cylinder 81. One end of the mounting block 10 then abuts against the triangular fixing block 84. Further pushing the mounting block 10 into the inner cavity of the tool fixing cylinder 81 causes the triangular fixing block... 84. Press the mounting block 10, causing it to push the guide block 13 into the slot outside the fixing rod 22, further engaging the fixing rod 22 to ensure the stability of the tool body 11. After the gear 24 meshes with the rack 83, it pushes the mounting block 10 to slide within the tool fixing cylinder 81, and the gear 24 rotates along the rack 83. To remove the mounting block 10, turn the knob 9 to rotate the transmission bevel gear 20, causing it to mesh with the driven bevel gear 17, which in turn drives... The U-shaped fixing block 18 rotates, causing the ratchet catch block inside the U-shaped fixing block 18 to engage with the ratchet 26, thereby driving the gear 24 to rotate. The gear 24 then meshes with the rack 83, causing it to rotate and thus removing the mounting block 10 from the inner cavity of the tool fixing cylinder 81. Without turning the knob 9, the ratchet 26, in conjunction with the ratchet catch block, fixes the gear 24. Simultaneously, the gear 24 meshes with the rack 83, preventing the removal of the mounting block 10. This ensures the stability of the tool body 11 after installation and solves the problem of tool mounting and fixing in existing CNC lathes. When installing and fixing cutting tools, bolts are usually used in conjunction with limiting washers to limit and fix the tools to the tool holder. When the bolts are tightened for the first time, a certain preload is required to ensure the fixing effect. However, during long-term operation, due to factors such as vibration and temperature changes, the preload will gradually decrease, causing the tool to loosen. Moreover, if the tool needs to be replaced frequently, the preload required when the bolts are tightened for the first time will increase the difficulty for the operator to loosen the bolts and make tool replacement more time-consuming and laborious. Example 2

[0033] like Figure 4 , Figure 6 and Figure 8 As shown, a rack 83 is installed on the upper end face of the limiting rod 82, and the rack 83 is meshed with the gear 24. Two triangular fixing blocks 84 are symmetrically fixed on one side of the inner cavity of the tool fixing cylinder 81, and the two triangular fixing blocks 84 are used to abut against the mounting block 10 for installation.

[0034] like Figure 1 , Figure 2 and Figure 7As shown, a solid-liquid separation drawer 5 is slidably arranged on the lower part of the front end face of the CNC machine tool body 1. A filter screen plate 27 is installed in the inner cavity of the solid-liquid separation drawer 5. A liquid recovery port 28 is opened at the bottom of the inner cavity of the solid-liquid separation drawer 5 for liquid recycling and reuse.

[0035] like Figure 1 , Figure 6 and Figure 7 As shown, one end of the mounting block 10 is triangular and is used to insert into the inner cavity of the tool fixing cylinder 81. The surface of the mounting block 10 abuts against the triangular fixing block 84 to press the mounting block 10 to clamp the fixing rod 22.

[0036] Specifically, when the tool body 11 is used to turn the workpiece, the tool is cooled by spraying water through a conduit. The wastewater and debris generated by the tool body 11 during turning the workpiece will flow into the inner cavity of the solid-liquid separation drawer 5. The inner cavity of the solid-liquid separation drawer 5 is equipped with a filter screen 27, which filters the debris in the wastewater. The bottom of the inner cavity of the solid-liquid separation drawer 5 is provided with a liquid recovery port 28, which can recover the filtered wastewater and reuse it, thereby improving the overall practicality of the CNC machine tool.

[0037] like Figure 1 and Figure 2 As shown, a triangular chuck 7 is installed on one side of the inner cavity of the CNC machine tool body 1, and a control console 6 is provided on one side of the front end face of the protective shell 2.

[0038] The working principle is as follows: When installing the tool body 11, the fixing rod 22 is held and the abutment 23 is inserted into the mounting groove 12. The abutment 23 slides on the surface of the two guide blocks 13, and then the abutment 23, together with the two guide blocks 13, pushes the mounting block 10 to expand. After the abutment 23 slides into the inner cavity of the mounting groove 12, the mounting block 10 drives the guide blocks 13 to spring back and reset, thereby limiting the abutment 23. Then, the mounting block 10 is inserted into the inner cavity of the tool fixing cylinder 81, and the tool fixing cylinder 81 presses the mounting block 10. At the same time, the mounting block 10 pushes the guide blocks 13 to press and fix the fixing rod 22, thereby ensuring the stability of the tool body 11. When the length of the tool body 11 needs to be adjusted, the threaded sleeve 16 is driven to rotate by turning the knob 9. At the same time, the threaded sleeve 16 drives the threaded telescopic rod 15 to rotate, which in turn causes the threaded telescopic rod 15 to slide inside the mounting block 10. This causes the threaded telescopic rod 15 to drive the push plate 14 to slide in the inner cavity of the mounting groove 12, so that the push plate 14 abuts against the block 23. Then, the push plate 14 pushes the block 23 to drive the fixing rod 22 to move into the inner cavity of the tool fixing cylinder 81. At the same time, the fixing rod 22 drives the tool body 11 to slide out of the tool fixing cylinder 81 to adjust its position. When installing the tool body 11, the mounting block 10 is inserted into the inner cavity of the tool fixing cylinder 81. Simultaneously, the mounting block 10 slides outside the limiting rod 82 via the groove 25, and the limiting rod 82 limits and stabilizes the mounting block 10. At the same time, the mounting block 10 drives the gear 24 to mesh with the rack 83, pushing the mounting block 10 into the inner cavity of the tool fixing cylinder 81. One end of the mounting block 10 is also in contact with the triangular fixing block 84. Continuing to push the mounting block 10 into the inner cavity of the tool fixing cylinder 81 causes the triangular fixing block 84 to press against the mounting block 10, and the mounting block 10 pushes the guide block 13 into the slot outside the fixing rod 22, further engaging and locking the fixing rod 22 to ensure the stability of the tool body 11. Furthermore, after the gear 24 meshes with the rack 83, it pushes the mounting block... The mounting block 10 slides within the inner cavity of the tool fixing cylinder 81, while the gear 24 rotates along the rack 83. When the mounting block 10 needs to be removed, the knob 9 is turned to rotate the transmission bevel gear 20, which meshes with the driven bevel gear 17. Simultaneously, the driven bevel gear 17 rotates the U-shaped fixing block 18, causing the ratchet block inside the U-shaped fixing block 18 to engage with the ratchet 26, which in turn drives the gear 24 to rotate. The gear 24 then meshes with the rack 83 and rotates, thereby removing the mounting block 10 from the inner cavity of the tool fixing cylinder 81. Without turning the knob 9, the ratchet 26, in conjunction with the ratchet block, will fix the gear 24. At the same time, the gear 24 meshes with the rack 83, preventing the mounting block 10 from being removed, thus ensuring the stability of the tool body 11 after installation.
