Description

Technical Field

[0001] This invention relates to tool release technology for horizontal machine tools, specifically to a lever-assisted mechanical tool release mechanism for horizontal machine tools. Background Technology

[0002] Current machine tool tool release mechanisms are mainly divided into three types: hydraulically driven, pneumatically driven, and servo-electric. Each mechanism has its own characteristics, but also has certain problems that affect its application effect in actual production. Specifically, the problems are as follows: Limitations of Hydraulic / Pneumatic Systems: Early and current hydraulic tool release systems in most machine tools inevitably suffer from hydraulic oil leakage. This not only pollutes the working environment and increases oil consumption, but more seriously, oil seepage into the spindle bearing area can lead to lubrication failure and premature spindle system damage. While pure pneumatic systems avoid oil pollution, they often require larger cylinder diameters and higher air pressures to generate sufficient tool release force, resulting in high energy consumption and noise. Some compromise solutions employ pneumatic-hydraulic booster systems, which, while balancing power output and environmental friendliness to some extent, actually increase system complexity and potential failure points.

[0003] Spindle bearing life issues: In most domestic machining centers, the tool release mechanism of the spindle directly applies the tool release force to the spindle bearing. During the tool release process, a huge axial force is transmitted through the bearing. This periodic impact load significantly reduces the precision and life of the spindle bearing. Especially in heavy cutting and high-speed machining applications, the spindle system already bears a large working load. The added impact force of tool release further accelerates the fatigue failure of the bearing raceway and rolling elements, ultimately leading to loss of spindle precision and deterioration of machining quality.

[0004] System complexity and maintenance costs: Traditional tool release mechanisms typically include numerous components such as hydraulic pump stations, control valve groups, actuator cylinders, and connecting pipelines, resulting in a complex system structure and large space occupation. This not only increases the manufacturing cost of the machine tool but also leads to more potential failure points and makes maintenance and repair difficult. Once a system malfunctions, it often requires professional technicians to conduct lengthy troubleshooting and debugging, significantly reducing the overall efficiency of the equipment.

[0005] Energy efficiency issues: Traditional tool change systems require maintaining a certain system pressure even during non-tool change periods to prepare for tool change commands at any time. This constant pressure results in continuous energy consumption. This energy waste is particularly significant in machining applications requiring frequent tool changes, contradicting the current trend of green and energy-saving development in manufacturing.

[0006] Based on the shortcomings of the existing technology, we propose a lever-assisted mechanical tool release mechanism for horizontal machine tools. Summary of the Invention

[0007] The purpose of this invention is to provide a lever-assisted mechanical tool release mechanism for horizontal machine tools to overcome the shortcomings of the prior art.

[0011] Furthermore, the tool fixing mechanism includes a fixed column slidably connected to the mounting box, a telescopic rod fixedly connected to one side of the fixed column, a first transmission inclined block fixedly connected to one end of the telescopic rod, a fourth spring fixedly sleeved on the outer surface of the telescopic rod, a sixth spring fixedly connected to the mounting box on one side of the first transmission inclined block, and a pressing transmission mechanism driving the first transmission inclined block to move.

[0012] Furthermore, the extrusion transmission mechanism includes a second pressing column that is slidably connected to the mounting box. A fifth spring that is fixedly connected to the mounting box is fixedly sleeved on the outer surface of the second pressing column. A second transmission inclined block that is slidably connected to the mounting box is fixedly connected to the bottom end of the second pressing column.

[0013] Furthermore, a fixing groove is provided on one side of the fixing column, and a toggle column is fixedly connected to one side of the fixing column.

[0014] Furthermore, the tool cleaning mechanism includes a telescopic drive component fixedly connected to the mounting plate.

[0016] Furthermore, the liquid supply mechanism includes a water pump fixedly connected to the mounting plate, the output end of the water pump is fixedly connected to a first hose fixedly connected to a second transmission box, and the outer surface of the coil is fixedly connected to a second hose fixedly connected to the first hose.

[0017] Furthermore, a tool body is slidably connected within the spindle body.

[0018] Compared with the prior art, the lever-assisted force-multiplying mechanical tool release mechanism for horizontal machine tools provided by the present invention has the following beneficial effects: By employing mechanical transmission, the traditional pneumatic and hydraulic extrusion methods are eliminated, fundamentally preventing hydraulic oil leakage that pollutes the environment and affects spindle lubrication. It also avoids the drawbacks of pneumatic systems, such as high energy consumption and noise, as well as the complexity and numerous potential failure points of pneumatic-hydraulic pressurization systems. Furthermore, through multi-stage lever transmission, the force generated by the first pressure column is amplified step by step, ultimately generating a significant release force on the spindle drawbar spring. This release force does not generate impact force on the spindle bearings, reducing the impact load on the bearings and improving their precision and lifespan. Thirdly, the structure is simple, occupies little space, reduces manufacturing costs, has fewer potential failure points, and is easy to maintain and repair, improving the overall efficiency of the equipment. It also aligns with green energy-saving trends, with no continuous energy consumption during non-tool-changing periods.

[0019] Since it does not involve a hydraulic system, it fundamentally avoids the problem of hydraulic oil leakage, does not pollute the working environment, and will not cause lubrication failure due to oil seepage into the spindle bearing area, thus avoiding premature damage to the spindle system. At the same time, compared with a pure pneumatic system, it does not require a large cylinder diameter and high air source pressure to generate tool release force, and does not have problems such as high energy consumption and high noise. It also does not have the system complexity and many failure points of a pneumatic-hydraulic booster system, effectively solving many drawbacks of traditional hydraulic / pneumatic systems.

[0020] The tool release force is generated by a lever-assisted force-multiplying mechanism, rather than being applied directly to the spindle bearing. During tool release, the huge axial force is avoided from being transmitted through the bearing, reducing the impact of periodic impact loads on the spindle bearing. This significantly improves the precision and lifespan of the spindle bearing, especially in heavy cutting and high-speed machining applications. It effectively prevents the accelerated fatigue failure of the bearing raceway and rolling elements caused by the superimposed tool release impact force, ensuring spindle accuracy and machining quality.

[0021] Compared to traditional tool release mechanisms that involve numerous components such as hydraulic pump stations, control valve groups, actuator cylinders, and connecting pipelines, mechanical tool release systems have a simpler structure and occupy less space. This not only reduces the manufacturing cost of the machine tool but also reduces potential points of failure, making maintenance and repair relatively easy. Even if a malfunction occurs, it does not require lengthy troubleshooting and debugging by specialized technicians, thus improving the overall efficiency of the equipment.

[0022] With a mechanical tool release mechanism, there is no need to maintain system pressure during non-tool-changing periods, and there is no continuous energy consumption. Tool release force is generated through mechanical transmission only when tool release is required. For machining applications that require frequent tool changes, this effectively avoids energy waste and aligns with the current trend of green and energy-saving development in the manufacturing industry.

[0023] During tool installation, the telescopic drive unit moves the second transmission box, and the transmission mechanism causes the transmission ring and ring tube to rotate reciprocally. The water pump delivers cleaning fluid through a hose into the ring tube, which is then sprayed out by the flushing nozzle. Combined with the reciprocating movement and rotation, this thoroughly rinses the surface of the tool body, effectively removing stains and debris and preventing them from entering the spindle body's fixed cavity and causing damage, thus greatly improving the stability of tool installation. During tool machining, the flushing nozzle continuously sprays coolant, thoroughly rinsing and cooling the surface of the tool body. This promptly removes the heat generated during machining, preventing the tool from losing hardness and strength due to high temperatures, effectively reducing tool wear, further extending tool life, lowering tool replacement frequency and costs, and improving machining efficiency and quality.

A lever arm transmission mechanism that is connected to the first transmission box 4 is fixedly connected to one end of the transmission rope 12. The lever arm transmission mechanism is used to drive the transmission rope 12 to move.

[0030] The lever arm transmission mechanism includes a transmission column 21 slidably connected to the first transmission box 4. The bottom end of the transmission column 21 is fixedly connected to the transmission rope 12. The top end of the transmission column 21 is fixedly connected to the transmission frame 22. The lever arm 23 is rotatably connected inside the transmission frame 22. The lever arm 23 is rotatably connected to the first transmission box 4. The lever ratio of the lever arm 23 is 1:3. A transmission groove 24 is opened on the lever arm 23. A transmission block 25 is slidably connected inside the transmission groove 24. A connecting shaft 26 is fixedly connected to the transmission block 25. A transmission rod 27 is rotatably connected to the connecting shaft 26. The top end of the transmission rod 27 is fixedly connected to a first pressing column 28 slidably connected to the first transmission box 4. A third spring 29 is fixedly sleeved on the outer surface of the first pressing column 28.

[0031] The tool fixing mechanism includes a fixing post 31 that is slidably connected to the mounting box 7. A telescopic rod 32 is fixedly connected to one side of the fixing post 31. A first transmission inclined block 33 is fixedly connected to one end of the telescopic rod 32. A fourth spring 34 is fixedly sleeved on the outer surface of the telescopic rod 32. A sixth spring 38 that is fixedly connected to the mounting box 7 is fixedly connected to one side of the first transmission inclined block 33. A pressing transmission mechanism is driven to one side of the first transmission inclined block 33. The pressing transmission mechanism is used to drive the first transmission inclined block 33 to move.

[0032] The extrusion transmission mechanism includes a second pressing column 35 that is slidably connected to the mounting box 7. A fifth spring 36 that is fixedly connected to the mounting box 7 is fixedly sleeved on the outer surface of the second pressing column 35. A second transmission inclined block 37 that is slidably connected to the mounting box 7 is fixedly connected to the bottom end of the second pressing column 35. The second transmission inclined block 37 is slidably connected to the first transmission inclined block 33.

[0033] One side of the fixed column 31 has a fixed inclined groove, and a toggle column is fixedly connected to one side of the fixed column 31.

[0034] First, the machine tool is in its initial state. Then, the contact plate is fixedly installed on the spindle box 1 of the horizontal machine tool. At this time, the drawbar spring of the spindle body 2 is in its normal extended state, tightly clamping the tool body 8 on the spindle body 2. When it is necessary to release the spindle tool, the spindle box 1, mounting plate 3, first transmission box 4 and mounting box 7 are moved towards the contact plate. First, the second pressing column 35 on the mounting box 7 contacts the contact plate, and then the second pressing column 35 is squeezed. The second pressing column 35 moves downward within the mounting box 7, compressing the fifth spring 36. Simultaneously, the second pressing column 35 drives the second transmission inclined block 37 downward, which in turn drives the first transmission inclined block 33. The first transmission inclined block 33 then drives the telescopic rod 32 and the fixed column 31 to move. At this point, the sixth spring 38 begins to compress, and the fixed column 31 moves out of the mounting box 7, causing the fixing groove at one end of the fixed column 31 to abut against the inclined groove of the tool body 8, thus squeezing and fixing the tool body 8 to prevent it from falling off automatically during subsequent tool release. The spindle box 1 then continues to move upward, at which point the first pressing column 28 of the spindle box 1 abuts against the contact plate. The second pressing column 35 also continues to press downward. The first transmission inclined block 33 drives the telescopic rod 32 and the fourth spring 34 to retract, ensuring that the fixing groove of the fixed column 31 remains within the inclined groove of the tool body 8, fixing the tool body 8. Simultaneously, the first pressing column 28 drives the transmission rod 27 downward, thus... The movable rod 27 drives the lever arm 23 to rotate via the connecting shaft 26 and the transmission block 25. The lever arm 23 drives the transmission column 21 to move upward via the transmission frame 22. The transmission column 21 drives the transmission rope 12 to pull upward. At this time, due to the rotation of the lever arm 23, a large pulling force is generated on the transmission column 21 and the transmission rope 12 through the lever principle. Subsequently, the transmission rope 12 changes the direction of the pulling force through the fixed pulley 11. Then, the transmission rope 12 drives the movable pulley 13 to rotate. The transmission rope 12 drives the first transmission rack 14 to generate a large pulling force through the movable pulley 13. Then, the first transmission rack 14 drives the large gear 15 to rotate. The large gear 15 drives the small gear 17 to rotate through the transmission shaft 16. The small gear 17 drives the second transmission rack 18 to move. At this time, through the lever principle generated between the large gear 15 and the small gear 17, the second transmission rack 18 generates a large force. Then, the second transmission rack 18 drives the pressing block 19 to move downward. The pressing block 19 drives the pressing release column 5 to move downward. The squeezing release pin 5 exerts a downward squeezing force on the drawbar spring at the top of the spindle body 2, fully compressing the spindle drawbar disc spring. At this point, the clamping force on the tool disappears, the tool release action is completed, and the tool can move freely on the spindle body 2. Thus, utilizing the lever principle, the squeezing force generated by the first pressing pin 28 when driving the spindle to move is gradually increased, so that it generates a larger tool release squeezing force on the drawbar spring on the spindle body 2 through mechanical transmission, replacing the traditional pneumatic and hydraulic squeezing methods.Then, by actuating the actuating pin on the fixing pin 31, the fixing pin 31 is moved, causing it to be pulled out of the inclined groove of the tool body 8. The tool body 8 is then removed from the spindle body 2 using a tool clamping tool. The tool to be replaced is then inserted into the tool body 8, and the fixing pin 31 secures it. The spindle box 1 is then moved, causing the first pressing pin 28 to no longer be pressed. At this point, the drawbar spring is no longer compressed, clamping and fixing the tool body 8. Subsequently, the second pressing pin 35 is no longer compressed, and the fixing pin 31 no longer secures the tool body 8, thus achieving mechanical tool release of the tool body 8.

[0035] In summary, this solution employs a mechanical cutter release mechanism, which offers the following advantages: 1. This solution does not involve a hydraulic system, fundamentally avoiding hydraulic oil leakage problems, preventing pollution of the working environment, and preventing lubrication failure due to oil seepage into the spindle bearing area, thus avoiding premature damage to the spindle system; at the same time, compared with a pure pneumatic system, it does not require a large cylinder diameter and high air source pressure to generate tool release force, and does not have problems such as high energy consumption and high noise; it also does not have the system complexity and many failure points of a pneumatic-hydraulic booster system, effectively solving many drawbacks of traditional hydraulic / pneumatic systems.

[0036] 2. The tool release force is generated through a lever-assisted force-multiplying mechanism, rather than being applied directly to the spindle bearing. During the tool release process, the huge axial force is avoided from being transmitted through the bearing, reducing the impact of periodic impact loads on the spindle bearing. This significantly improves the precision and lifespan of the spindle bearing, especially in heavy cutting and high-speed machining applications. It effectively prevents the accelerated fatigue failure of the bearing raceway and rolling elements caused by the superimposed tool release impact force, ensuring spindle precision and machining quality.

[0037] 3. The mechanical tool release mechanism mainly consists of a spindle box 1, mounting plate 3, first transmission box 4, pressing tool release column 5, lever transmission mechanism, lever arm transmission mechanism, and tool fixing mechanism. Compared with traditional tool release mechanisms that include numerous components such as hydraulic pump station, control valve group, actuator cylinder and connecting pipelines, the system structure is simple and occupies less space. This not only reduces the manufacturing cost of the machine tool, but also reduces the number of failure points, making maintenance and repair relatively easy. Even if a fault occurs, it does not require professional technicians to spend a long time troubleshooting and debugging, thus improving the overall efficiency of the equipment.

[0038] 4. The mechanical tool release mechanism does not require maintaining system pressure during non-tool-changing periods, thus eliminating continuous energy consumption. Tool release force is generated mechanically only when a tool release operation is needed. For machining applications requiring frequent tool changes, this effectively avoids energy waste and aligns with the current trend of green and energy-saving development in the manufacturing industry.

[0039] Example 2 Based on Example 1, please refer to Figure 1 and Figure 6 As shown, the tool cleaning mechanism includes a telescopic drive component 41 fixedly connected to the mounting plate 3. The telescopic drive component 41 is an electric telescopic rod. A connecting plate 42 is fixedly connected to the output end of the telescopic drive component 41. A second transmission box 43 is fixedly connected to one side of the connecting plate 42. A transmission ring 44 is rotatably connected inside the second transmission box 43. A ring tube 45 is fixedly connected to the transmission ring 44. Multiple cleaning tubes 46 are fixedly connected to the outer surface of the ring tube 45. A rinsing nozzle 47 is fixedly connected to one end of the cleaning tube 46. A transmission mechanism connected to the second transmission box 43 is driven to the outer surface of the transmission ring 44. The transmission mechanism is used to drive the transmission ring 44 to rotate. A liquid supply mechanism connected to the mounting plate 3 is fixedly connected to the outer surface of the ring tube 45. The liquid supply mechanism is used to supply liquid to the ring tube 45.

[0040] The transmission mechanism includes a rotation drive component 51 fixedly connected to the second transmission box 43. The rotation drive component 51 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles. The output end of the rotation drive component 51 is fixedly connected to a drive shaft 52. A drive gear 53 is fixedly sleeved on the outer surface of the drive shaft 52. A transmission gear ring 54 fixedly connected to the transmission ring 44 is meshed on the outer surface of the drive gear 53. The rotation drive component 51 drives the drive shaft 52 to rotate, and the drive shaft 52 drives the transmission ring 44 to rotate through the drive gear 53.

[0041] The liquid supply mechanism includes a water pump 61 fixedly connected to the mounting plate 3, a first hose 62 fixedly connected to the output end of the water pump 61 and fixedly connected to the second transmission box 43, and a second hose 63 fixedly connected to the first hose 62 and fixedly connected to the outer surface of the coil 45.

[0042] During the tool installation process, the tool body 8 is placed into the mounting hole of the spindle body 2. Then, the connecting plate 42 is moved by the telescopic drive component 41, and the connecting plate 42 moves the second transmission box 43. At the same time, the transmission mechanism drives the transmission ring 44 to reciprocate, and the transmission ring 44 drives the ring tube 45 to reciprocate. Simultaneously, the water pump 61 sends cleaning fluid into the ring tube 45 through the first hose 62 and the second hose 63. The ring tube 45 sprays the cleaning fluid out through the cleaning pipe 46 and the flushing nozzle 47, while simultaneously driving the reciprocating movement and rotation of the transmission ring 44 and the ring tube 45. This allows the cleaning fluid to thoroughly rinse the surface of the tool body 8, cleaning away surface dirt and preventing dirt or debris from entering the fixed cavity of the spindle body 2 and causing damage. This further improves the stability of the tool body 8 installed in the spindle body 2. During the tool processing, the flushing nozzle 47 thoroughly rinses the surface of the tool body 8 with coolant, achieving comprehensive cooling of the tool body 8 and further improving its service life.

[0043] Working principle: First, the machine tool is in the initial state. Then, the contact plate is fixedly installed on the spindle box 1 of the horizontal machine tool. At this time, the drawbar spring of the spindle body 2 is in the normal extended state, tightly clamping the tool body 8 on the spindle body 2. When it is necessary to release the spindle tool, the spindle box 1, mounting plate 3, first transmission box 4 and mounting box 7 are moved towards the contact plate. First, the second pressing column 35 on the mounting box 7 contacts the contact plate, and then the second pressing column 35 is squeezed. The second pressing column 35 moves downward within the mounting box 7, compressing the fifth spring 36. Simultaneously, the second pressing column 35 drives the second transmission inclined block 37 downward, which in turn drives the first transmission inclined block 33. The first transmission inclined block 33 then drives the telescopic rod 32 and the fixed column 31 to move. At this point, the sixth spring 38 begins to compress, and the fixed column 31 moves out of the mounting box 7, causing the fixing groove at one end of the fixed column 31 to abut against the inclined groove of the tool body 8, thus squeezing and fixing the tool body 8. Subsequently, the spindle box 1 continues to move upward, at which point the first pressing column 28 of the spindle box 1 begins to abut against the contact plate. At this point, the second pressing column 35 also continues to press downward. The first transmission inclined block 33 drives the telescopic rod 32 and the fourth spring 34 to retract, ensuring that the fixing groove of the fixed column 31 remains within the inclined groove of the tool body 8, thus fixing the tool body 8. Simultaneously, the first pressing column 28 drives the transmission rod 27 downward, which, through the connecting shaft 26 and... The transmission block 25 drives the lever arm 23 to rotate. The lever arm 23 drives the transmission column 21 to move upward through the transmission frame 22. The transmission column 21 drives the transmission rope 12 to pull upward. At this time, due to the rotation of the lever arm 23, a large pulling force is generated on the transmission column 21 and the transmission rope 12 through the lever principle. Then, the transmission rope 12 changes the direction of the pulling force through the fixed pulley 11. Subsequently, the transmission rope 12 drives the movable pulley 13 to rotate. The transmission rope 12 drives the first transmission rack 14 to generate a large pulling force through the movable pulley 13. Then, the first transmission rack 14 drives the large gear 15 to rotate. The large gear 15 drives the small gear 17 to rotate through the transmission shaft 16. The small gear 17 drives the second transmission rack 18 to move. At this time, through the lever principle generated between the large gear 15 and the small gear 17, the second transmission rack 18 generates a large force. Subsequently, the second transmission rack 18 drives the pressing block 19 to move downward. The pressing block 19 drives the pressing release column 5 to move downward. The squeezing release pin 5 exerts a downward squeezing force on the drawbar spring at the top of the spindle body 2, fully compressing the spindle drawbar disc spring. At this point, the clamping force on the tool disappears, the tool release action is completed, and the tool can move freely on the spindle body 2. Thus, utilizing the lever principle, the squeezing force generated by the first pressing pin 28 when driving the spindle to move is gradually increased, so that it generates a larger tool release squeezing force on the drawbar spring on the spindle body 2 through mechanical transmission, replacing the traditional pneumatic and hydraulic squeezing methods. Subsequently, by actuating the actuating pin on the fixed pin 31,The actuating column moves the fixing column 31, pulling it out of the inclined groove of the tool body 8. Then, the tool body 8 is removed from the spindle body 2 using a tool clamping tool. The tool to be replaced is then inserted into the tool body 8, and the fixing column 31 secures it. The spindle box 1 then moves, removing the first pressing column 28 from its contact point. At this point, the drawbar spring is no longer compressed, clamping and securing the tool body 8. Subsequently, the second pressing column 35 is no longer compressed, and the fixing column 31 no longer secures the tool body 8, thus achieving mechanical tool release.

[0044] During the tool installation process, the tool body 8 is placed into the mounting hole of the spindle body 2. Then, the connecting plate 42 is moved by the telescopic drive component 41, and the connecting plate 42 moves the second transmission box 43. At the same time, the transmission mechanism drives the transmission ring 44 to reciprocate, and the transmission ring 44 drives the ring tube 45 to reciprocate. Simultaneously, the water pump 61 sends cleaning fluid into the ring tube 45 through the first hose 62 and the second hose 63. The ring tube 45 sprays the cleaning fluid out through the cleaning pipe 46 and the flushing nozzle 47, while simultaneously driving the reciprocating movement and rotation of the transmission ring 44 and the ring tube 45. This allows the cleaning fluid to thoroughly rinse the surface of the tool body 8, cleaning away surface dirt and preventing dirt or debris from entering the fixed cavity of the spindle body 2 and causing damage. This further improves the stability of the tool body 8 installed in the spindle body 2. During the tool processing, the flushing nozzle 47 thoroughly rinses the surface of the tool body 8 with coolant, achieving comprehensive cooling of the tool body 8 and further improving its service life.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
