[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0045] like Figures 1-4 As shown, an embodiment of the present invention provides a multifunctional gear hobbing machine for gear processing, including a base 1, one side of the surface of the base 1 is slidably connected to a stand B11, and the other side of the surface of the base 1 is fixedly connected to a stand A2, the side of the stand B11 is slidably connected to a first Y-axis motion panel 7, and the surface of the first Y-axis motion panel 7 is rotatably connected to a rotating panel 8, the surface of the rotating panel 8 is slidably connected to a first Z-axis motion panel 18, and a hob assembly is provided on the surface of the first Z-axis motion panel 18.

[0046] The side of the stand A2 is slidably connected to the second Z-direction motion panel 3, and the surface of the second Z-direction motion panel 3 is slidably connected to the second Y-direction motion panel 4, and the surface of the second Y-direction motion panel 4 is installed with a power turret assembly.

[0047] The surface of the stand A2 is slidably connected to a third Y-direction motion panel 5 , and a thimble tailstock 6 is mounted on the surface of the third Y-direction motion panel 5 .

[0048] A rotating base 10 is installed on the surface of the base 1 , and a clamping chuck 9 is provided on the surface of the rotating base 10 .

[0049] The cutter assembly comprises a cutter spindle driving motor 30, which is installed on the surface of the first Z-direction movement panel 18, and a support bearing 31 is installed on the surface of the first Z-direction movement panel 18, and the inside of the support bearing 31 is rotatably installed with a cutter spindle 17, and the output end of the cutter spindle driving motor 30 is connected with one end of the cutter spindle 17, and a cutter unloading cylinder 32 is installed on the side surface of the first Z-direction movement panel 18, and the position of the cutter unloading cylinder 32 corresponds to the position of the cutter spindle 17.

[0050] The cutter spindle driving motor 30 can drive the cutter spindle 17 to rotate in the mode of motor direct driving or motor driving combined with belt driving. The latter is preferred, because the mode of motor driving combined with belt driving can effectively reduce the impact force when the motor starts, and at the same time, it can provide higher transmission efficiency and more stable transmission performance, and adapt to the load changes under different working conditions. In addition, the belt driving mode also has a certain buffering effect, which can prolong the service life of the cutter spindle 17 and related transmission components, and reduce the maintenance cost.

[0051] The power cutter tower assembly comprises a mounting seat 36, which is arranged on the surface of the second Y-direction movement panel 4, and the surface of the mounting seat 36 is rotatably installed with a power cutter tower cutter disc 28, and the surface of the power cutter tower cutter disc 28 is provided with a plurality of cutters 29, and the side surface of the mounting seat 36 is installed with a cutter disc rotating motor 27 for driving the power cutter tower cutter disc 28 to rotate and switch. A positioning assembly is arranged between the power cutter tower cutter disc 28 and the mounting seat 36, which comprises high-precision positioning pins and spring-loaded positioning holes. When the power cutter tower cutter disc 28 rotates to the target cutter 29 position, the positioning pins are inserted into the positioning holes through the elastic action, so as to realize the accurate positioning of the power cutter tower cutter disc 28.

[0052] The high-precision positioning pins are installed on the surface of the mounting seat 36 and arranged near the outer edge of the rotating path of the power cutter tower cutter disc 28. The positioning pins are connected with the mounting seat 36 through spring loading devices, and the design of spring loading ensures that the positioning pins can quickly insert into the positioning holes when the cutter disc rotates to the target position, so as to realize the high-precision locking of the cutter disc. At the same time, the elastic recovery force of the spring enables the positioning pins to quickly rebound when the cutter disc continues to rotate, so as to prepare for the next positioning action.

[0053] The positioning holes corresponding to the positioning pins are uniformly distributed on the outer edge surface of the power cutter tower cutter disc 28, and the position of each positioning hole accurately matches the installation position of each cutter 29 on the cutter disc. The size tolerance of the positioning holes and the positioning pins is strictly controlled, so as to ensure that the cutter disc has sufficient rigidity and repeat positioning accuracy when positioned. In addition, in order to improve the reliability of positioning, wear-resistant bushings are arranged around the positioning holes, so as to reduce the influence of wear on the positioning accuracy during long-term use.

[0054] The surface of the mounting seat 36 is also provided with a tool rotating motor 26, the output shaft of the tool rotating motor 26 is connected with the main tool driving shaft of the current tool disc position through a shaft coupling, and only drives the current main tool 29 to rotate. In order to ensure the safety and accuracy of tool switching, a position detection device is arranged in the power tool turret assembly, including a rotary encoder and a limit switch. The rotary encoder detects the rotation angle of the power tool turret disc 28 in real time and provides accurate feedback information to the numerical control system; the limit switch is used for monitoring the end position of the tool disc switching action, so that the power tool turret disc 28 can be accurately stopped when rotating to the target tool.

[0055] In addition, the rotation of the power tool turret disc 28 is driven by the disc rotating motor 27 combined with high-torque reduction gear transmission, so as to improve the stability and impact resistance during rotation. In order to prevent overshoot or deviation caused by inertia during tool disc switching, a brake device is also arranged on the power tool turret disc 28, which is composed of an electromagnetic braking system, and a braking force is applied when the power tool turret disc 28 stops rotating, further improving the positioning accuracy.

[0056] In an embodiment of the utility model, the blank round bar to be processed is placed on the clamping chuck 9, and the clamping chuck 9 can firmly clamp one end of the blank round bar. Then, by moving the third Y-direction movement panel 5, the tailstock 6 can be driven to move downward, so that one end of the tailstock 6 accurately abuts against the top end of the blank round bar, thereby firmly limiting the blank round bar on the clamping chuck 9, ensuring the stability and accuracy during processing.

[0057] The hob assembly can perform gear hobbing operation on the blank round bar, specifically including tooth profile processing on the surface of the blank round bar according to the preset gear parameters, to form a gear profile meeting the design requirements. During processing, the hob main shaft driving motor 30 is started, the hob main shaft driving motor 30 drives the hob main shaft 17 to rotate rapidly on the supporting bearing 31, and the hob main shaft 17 performs efficient tooth profile cutting operation on the outer circular surface of the blank round bar.

[0058] The vertical seat B11 is used to drive the hob assembly to move accurately along the X-axis direction, the rotary panel 8 is used to drive the hob assembly to realize angle rotation adjustment, the first Y-direction movement panel 7 is used to drive the hob assembly to move downward along the Y-axis direction, and the first Z-direction movement panel 18 is used to drive the hob assembly to move along the Z-axis direction. Through the linkage control of these axial and rotary movements, the hob assembly can realize omnidirectional automatic movement in the XYZ-axis direction and the rotary axis direction, so as to complete complex gear hobbing operation at different angles and positions in gear processing.

[0059] The power turret assembly can realize various types of machining operations on the blank round bar by replacing different tools. The specific working process includes turning the outer diameter size of the blank round bar, drilling, cutting and other machining processes. During machining, by selecting appropriate tools and programming the rotation of the power turret cutter head 28 and the tool movement path, different process requirements can be met.

[0060] The power turret assembly takes the mounting seat 36 as the core, integrates the power turret cutter head 28, cutter head rotation motor 27 and tool rotation motor 26, and realizes multi-process machining of the blank round bar through close cooperation between components. The mounting seat 36 is fixed on the second Y-direction movement panel 4 to provide overall support, and through the multi-axis linkage of the second Y-direction movement panel 4 and the second Z-direction movement panel 3, the entire power turret assembly is driven to move along the Y-axis and Z-axis directions to accurately adjust the machining position. The cutter head rotation motor 27 drives the cutter head 28 to rotate quickly to switch the required tool 29, and each tool on the cutter head can be accurately positioned to the machining position to support different processes such as turning, drilling, cutting, etc. The tool rotation motor 26 drives the selected tool to rotate for cutting operation to meet complex machining requirements while ensuring machining stability and accuracy.

[0061] The tool rotation motor 26 works with the precision transmission device of the power turret cutter head 28 to accurately drive a single predetermined tool. After the cutter head rotation motor 27 rotates the cutter head 28 to the main tool position of the target tool, the tool rotation motor 26 is connected to the target tool through a shaft coupling or spline shaft, and only drives the main tool position tool to rotate, while other tools are in idle state. This design utilizes the cooperative control of precision mechanical transmission structure and numerical control system to ensure accurate power transmission during tool switching. Through sensor detection and automatic docking mechanism, the system can confirm the accuracy of cutter head positioning in real time to avoid misoperation. At the same time, some advanced systems can realize multi-station support through electromagnetic clutch device to further improve machining efficiency.

[0062] During machining, each component is controlled by the numerical control system to realize automatic adjustment of the machining path and process. The efficiency of the power turret assembly not only lies in the rapid switching and accurate positioning of the tools, but also benefits from the combination of the existing cooling system and tool detection function. The cooling system can reduce the temperature of the machining area to prolong the tool life; the tool detection device monitors the tool wear or abnormal state in real time to ensure the machining quality and safety. Through the combination of multi-axis linkage and tool selection function, the power turret assembly can complete the whole process operation of the blank round bar from rough machining to finish machining, greatly improving the production efficiency and machining precision.

[0063] The second Y-direction moving panel 4 is used to drive the power tool turret assembly to move along the Y-axis direction, so as to realize the machining operation at different height positions of the blank round bar; and the second Z-direction moving panel 3 is used to drive the power tool turret assembly to move along the Z-axis direction, so as to accurately adjust the position of the machining tool, and to complete the precise turning, cutting and other auxiliary machining processes. In this way, through the multi-axis linkage and the switching of different tools, the efficient integrated processing of the blank round bar from the rough machining to the finished product can be realized.

[0064] In the embodiment, the surface of the base 1 and the pedestal B11 are jointly provided with an X-direction driving assembly, and the X-direction driving assembly is used to drive the pedestal B11 to move along the X-direction on the surface of the base 1.

[0065] The X-direction driving assembly comprises an X-direction driving member 12, which is installed on the surface of the base 1. The surface of the base 1 is provided with an X-direction transmission screw, and the output end of the X-direction driving member 12 is connected with one end of the X-direction transmission screw. An X-direction transmission nut is engaged and connected to the outer side of the X-direction transmission screw, and the X-direction transmission nut is connected with the pedestal B11.

[0066] The surface of the base 1 is provided with an X-direction guide rail 13, and the pedestal B11 is slidingly connected on the X-direction guide rail 13.

[0067] The X-direction driving member 12 can drive the X-direction transmission screw to rotate in the mode of motor direct driving or motor driving combined with belt transmission. Preferably, the mode of motor driving combined with belt transmission is adopted, because this mode can effectively alleviate the torque impact when the motor starts, provide more stable transmission performance, and reduce the vibration and noise possibly caused by direct driving. The belt transmission also has a certain buffering effect, which can prolong the service life of the transmission system and the screw assembly, and adapt to the operation requirements under different load conditions.

[0068] When it is needed to drive the pedestal B11 to move along the X-direction on the surface of the base 1, the X-direction driving member 12 is started, and the X-direction driving member 12 drives the X-direction transmission screw to rotate through the output end thereof. The X-direction transmission nut engaged with the outer side of the X-direction transmission screw forms a spiral transmission therebetween, and the axial movement of the nut directly drives the pedestal B11 connected therewith to slide along the X-direction guide rail 13 of the base 1, so as to realize the accurate X-direction movement of the pedestal B11. Through the control of the operation parameters of the X-direction driving member 12 by the numerical control system, the movement speed and position of the pedestal B11 can be adjusted according to the machining requirements, and the accurate machining positioning can be realized.

[0069] In the embodiment, the surface of the pedestal B11 and the first Y-direction moving panel 7 are jointly provided with a first Y-direction driving assembly, and the first Y-direction driving assembly is used to drive the first Y-direction moving panel 7 to move along the Y-direction on the surface of the pedestal B11.

[0071] The surface of the stand B11 is provided with a first Y-direction guide rail 35, and the first Y-direction movement panel 7 is slidingly connected on the first Y-direction guide rail 35.

[0072] The first Y-direction driving member 16 can drive the first Y-direction transmission screw rod to rotate in the mode of motor direct drive or motor driving and cooperating with belt transmission. Preferably, the mode of motor driving and cooperating with belt transmission is adopted because this mode can effectively reduce the instantaneous torque impact when the motor starts and improve the stability of the transmission system. The belt transmission can also buffer the impact caused by load fluctuation, reduce vibration and noise, and prolong the service life of the screw rod and related transmission components. In addition, the flexibility of the belt transmission enables the equipment to maintain high efficiency under different processing conditions, which is convenient for maintenance and adjustment.

[0073] When it is needed to drive the first Y-direction movement panel 7 to move along the Y-direction on the surface of the stand B11, the first Y-direction driving member 16 is started.

The transmission nut is connected with the first Y-direction movement panel 7, so that when the transmission screw rod rotates, the axial movement of the transmission nut directly drives the first Y-direction movement panel 7 to slide along the surface of the stand B11. At the same time, the first Y-direction movement panel 7 is precisely guided by the first Y-direction guide rail 35, so as to maintain the stability and precision of movement. The speed and position of the first Y-direction driving member 16 are controlled by the numerical control system, so as to realize the high-precision positioning and multi-rate adjustment of the first Y-direction movement panel 7, and meet the needs of different processing procedures.

[0081] The first Z-direction driving member 33 can adopt a motor direct drive mode to drive the first Z-direction transmission screw to rotate. When it is needed to drive the first Z-direction moving panel 18 to move along the Z-direction on the surface of the rotating panel 8, the first Z-direction driving member 33 is started to drive the first Z-direction transmission screw to rotate through the output end thereof.

[0084] The second Z-direction driving assembly comprises a second Z-direction driving member 22, and the second Z-direction driving member 22 is installed on the surface of the stand A2. The surface of the stand A2 is rotatably installed with a second Z-direction transmission screw, and the outer side of the second Z-direction transmission screw is meshed and connected with a second Z-direction transmission nut, and the second Z-direction transmission nut is fixedly connected with the second Z-direction moving panel 3.

[0085] The surface of the stand A2 is provided with a second Z-direction guide rail 25, and the second Z-direction moving panel 3 is slidably connected on the second Z-direction guide rail 25.

[0086] The second Z-direction driving member 22 can adopt a motor direct drive mode to drive the second Z-direction transmission screw to rotate. When it is needed to drive the second Z-direction moving panel 3 to move along the Z-direction on the surface of the stand A2, the second Z-direction driving member 22 is started to drive the second Z-direction transmission screw to rotate through the output end thereof. The second Z-direction transmission screw and the second Z-direction transmission nut meshed with the outer side thereof form a screw transmission structure, and when the screw rotates, the transmission nut moves along the axis under the guidance of the screw, so as to drive the second Z-direction moving panel 3 fixedly connected therewith to slide along the Z-direction. The second Z-direction moving panel 3 is guided by the second Z-direction guide rail 25 on the surface of the stand A2, so as to ensure the straightness and stability of the movement.

[0087] The motor directly drives the second Z-direction transmission screw, which has the advantages of high transmission efficiency, high control accuracy and fast response speed, can directly transmit the power of the motor to the screw, and reduces the energy loss and error accumulation of the intermediate link. At the same time, the numerical control system can accurately control the second Z-direction driving member 22, adjust the speed and displacement of the second Z-direction motion panel 3, and meet various processing requirements. The cooperation of the guide rail and the screw ensures the stability and positioning accuracy of the motion panel during processing, making the overall system run more reliably and efficiently.

[0088] In this embodiment, the surface of the second Z-direction motion panel 3 and the second Y-direction motion panel 4 is provided with a second Y-direction driving assembly, and the second Y-direction driving assembly is used to drive the second Y-direction motion panel 4 to move along the Y-direction on the surface of the second Z-direction motion panel 3.

[0089] The second Y-direction driving assembly includes a second Y-direction driving member 24, which is installed on the surface of the second Y-direction motion panel 4. The surface of the second Y-direction motion panel 4 is rotatably installed with a second Y-direction transmission screw, and the outer side of the second Y-direction transmission screw is meshingly connected with a second Y-direction transmission nut. The second Y-direction transmission nut is fixedly connected with the second Z-direction motion panel 3. The surface of the second Y-direction motion panel 4 is installed with a second Y-direction guide rail 34, and the surface of the second Z-direction motion panel 3 is provided with a fixed sliding block 23. The second Y-direction guide rail 34 is slidably connected in the inside of the fixed sliding block 23.

[0090] The second Y-direction driving member 24 can drive the second Y-direction transmission screw to rotate in the form of motor direct drive. When it is needed to drive the second Y-direction motion panel 4 to move along the Y-direction on the surface of the second Z-direction motion panel 3, the second Y-direction driving member 24 is started, and the driving member directly drives the second Y-direction transmission screw to rotate through the output end thereof. Since the second Y-direction transmission nut is fixedly installed on the second Z-direction motion panel 3, the rotation of the transmission screw will generate an axial propelling force, which directly pushes the second Y-direction motion panel 4 to slide along the Y-direction guide rail 34, so as to realize the linear movement of the panel.

[0091] Driving the second Y-direction transmission screw in the form of motor direct drive has the advantages of fast response, high transmission efficiency and compact structure, can accurately control the rotation angle and speed of the screw, and directly drives the high-precision displacement adjustment of the second Y-direction motion panel 4. Through the precise regulation and control of the running parameters of the second Y-direction driving member 24 by the numerical control system, the motion speed and displacement range of the motion panel can be flexibly adjusted according to the processing requirements, so as to adapt to diversified processing tasks. In addition, the combination design of the fixed nut and the guide rail structure ensures the stability and linearity of the motion panel under high-speed and high-load operation, thereby improving the accuracy and reliability of the overall processing.

[0092] In the embodiment, the surface of the stand A2 and the third Y-direction movement panel 5 are jointly provided with a third Y-direction driving assembly, and the third Y-direction driving assembly is used to drive the third Y-direction movement panel 5 to move along the Y direction on the surface of the stand A2.

[0093] The third Y-direction assembly includes a third Y-direction driving member 21, which is installed on the surface of the stand A2. The side surface of the stand A2 is rotationally installed with a third Y-direction transmission screw 20, and the outer side of the third Y-direction transmission screw 20 is engaged with a third Y-direction transmission nut. The third Y-direction movement panel 5 is installed on the third Y-direction transmission nut.

[0094] The surface of the stand A2 is provided with a third Y-direction guide rail 19, and the third Y-direction movement panel 5 is slidingly connected to the third Y-direction guide rail 19.

[0095] The third Y-direction driving member 21 can drive the third Y-direction transmission screw 20 to rotate in a mode of motor direct drive or motor driving combined with gear transmission. When it is needed to drive the third Y-direction movement panel 5 to move along the Y direction on the surface of the stand A2, the third Y-direction driving member 21 is started, and the driving member drives the third Y-direction transmission screw 20 to rotate through its output end directly or through gear transmission. The third Y-direction transmission screw 20 and the third Y-direction transmission nut engaged with the outer side thereof form a screw transmission structure. When the screw rotates, the transmission nut moves along the axial direction, thereby driving the third Y-direction movement panel 5 installed thereon to slide on the surface of the stand A2. At the same time, the third Y-direction movement panel 5 is precisely guided by the third Y-direction guide rail 19, which ensures the stability and linearity of the movement along the Y direction.

[0096] The mode of motor direct drive can reduce the energy loss in the transmission chain and improve the response speed and positioning accuracy of the system. The mode of motor driving combined with gear transmission is suitable for application scenarios with high torque requirements, which can further optimize the output of driving force through gear speedup or speed reduction. Regardless of which mode is adopted, the operation of the third Y-direction driving member 21 is controlled by the numerical control system, which can adjust the movement speed and position of the third Y-direction movement panel 5 according to the processing requirements, and adapt to different process requirements. In addition, the cooperation design of the guide rail and the nut ensures the high stability and long service life of the movement panel under load change, thereby improving the overall processing efficiency and accuracy.

[0097] In summary, the utility model technical scheme through the comprehensive optimization to multi axle linkage, transmission structure, guide rail system and numerical control control, overall improvement the flexibility, stability and automation degree of processing equipment. The drive assembly of each movement component adopts high efficiency transmission design, for example, motor direct drive combines spiral transmission structure, realizes the high accuracy linear movement of movement component in multiple directions, and worm gear transmission guarantees the stability and positioning accuracy of rotating component. This diversified transmission mode meets the demand of different movement forms for complex processing technology, ensures that each component can realize accurate displacement adjustment and positioning under different working conditions.

[0098] The cooperation of transmission screw and transmission nut plays a key role in the system. Among them, the design of fixed nut effectively shares the transmission force, reduces the force loss in the transmission chain, and at the same time, the linear motion of the panel is driven by the screw rotation, which realizes higher transmission efficiency and positioning accuracy. The guide rail system provides reliable guide support for all moving panels, and the sliding connection structure reduces friction and shaking during movement, making the processing action more stable, and further improving the service life of the equipment.

[0099] Through the real-time control of numerical control system, each drive component can accurately adjust speed, stroke and direction according to processing demand, supporting various complex processing tasks. For example, the power tool tower component can move freely and accurately position in Y and Z directions, combined with the multifunctional operation of tool rotation, realizing integrated processing from rough machining to finish machining. The stable combination design of guide rail and sliding block not only guarantees high precision machining, but also improves the impact resistance of the equipment under high speed operation or high load processing conditions, thereby enhancing the overall stability of the equipment.

[0100] In addition, the optimized design of transmission structure effectively reduces noise and vibration, and the impact force when the motor starts is buffered through belt transmission or gear transmission, prolonging the service life of key components such as transmission screw and bearing. In the rotating component, the worm gear transmission scheme not only ensures the stability of the rotation process, but also provides good safety protection due to its self-locking characteristics, preventing accidental rotation or loosening during processing.

[0101] In summary, these technical schemes realize the installation of hobbing function stand 11 and turning and milling function stand A2 on the same base 1 respectively through the combination of accurate mechanical design and system electrical control, and share a rotating mechanism (rotating base 10 and fixed chuck 9) between the two stands, so as to realize the hobbing machining function by sharing the rotating mechanism with the hobbing stand 11, and realize the turning and milling machining function by sharing the rotating mechanism with the turning and milling tool holder stand 2.
