Description

Technical Field

[0001] This invention relates to the field of gear processing equipment, and more specifically to a multi-station gear processing equipment. Background Technology

[0002] In the field of gear machining, gear hobbing is a commonly used gear forming process and is widely used in the manufacturing of various transmission gears. Existing gear hobbing equipment typically includes a hobbing cutter and a workpiece support structure for mounting the gear to be machined. Tooth profile machining is achieved through the relative motion between the hobbing cutter and the gear to be machined.

[0003] In multi-station gear machining equipment, to improve machining efficiency, multiple stations are typically set up or a linkage transmission structure is constructed to automate workpiece position adjustment and feed motion during the machining process. However, in practical applications, the cutting motion of the hobbing cutter and the feed motion of the workpiece support assembly often have a certain coupling relationship. When these motions are driven by the same power source or transmission path, the following problems can easily arise: First, during machining, the rotation of the hobbing cutter, in addition to its use in gear cutting, may also affect the motion state of the workpiece support assembly through the transmission path, thereby causing mutual interference between the workpiece feed motion and the cutting motion, affecting the meshing stability between the hobbing cutter and the workpiece. Second, the motion control requirements for the workpiece support assembly differ at different machining stages, such as the initial workpiece positioning stage and the tooth cutting stage. If the relevant transmission relationship cannot be adjusted according to the working conditions, it is difficult to balance the flexibility of feed control and the stability of the cutting process.

[0004] Some existing equipment controls the transmission path by setting up a clutch or intermittent transmission structure, but such structures usually have problems such as complex structure, slow response or limited control accuracy, which makes it difficult to meet the requirements of motion coordination for high-precision gear machining. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-station gear processing equipment to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multi-station gear processing equipment includes a frame and a gear hobbing cutter rotatably connected to the frame, and further includes: a support assembly for mounting the gear to be processed; it is slidably connected to the frame and is located radially on the gear hobbing cutter; Transmission assembly: It is located between the support assembly and the gear hobbing cutter and is used to drive the movement of the support assembly; Decoupling component: Located between the gear hobbing cutter and the transmission component, and coaxial with the gear hobbing cutter; The decoupling component includes: a deformable radial member coaxially arranged with the hobbing cutter, wherein the deformable radial member is coupled simultaneously with the hobbing cutter and the transmission assembly in the first position, so that the hobbing cutter and the transmission assembly are in a transmission connection state; The deformable radial component is separated from the transmission assembly in the second position, so that the hobbing cutter is in a non-transmission connection state with the transmission assembly. In use, when the decoupling component is in the first position, the drive transmission component moves the support component so that the gear to be processed is in contact with the hobbing cutter. At this time, by adjusting the speed of the hobbing cutter, the decoupling component is moved to the second position, and the hobbing cutter rotates independently to process the gear to be processed.

[0007] The support assembly includes multiple mounting seats that are slidably connected to the frame. Each mounting seat is coaxially arranged with the spindle, and a pressure elastic element is provided between each mounting seat and the spindle. The pressure elastic element is used to buffer the gear being machined during tool setting to avoid the hobbing cutter from colliding with the tool.

[0008] The pressure elastic element includes a central shaft, and a plurality of second transmission elements are slidably connected to the central shaft in the radial direction. Each second transmission element is slidably connected to the central shaft in pairs, and each second transmission element is connected to the central shaft by a second spring.

[0009] Each of the mounting bases is provided with a telescopic member in the radial direction, which is used to connect two adjacent mounting bases.

[0010] The transmission assembly includes a drive disk coaxially arranged with the deformable radial component, and a transmission groove is formed on the drive disk. A transmission column adapted to the transmission groove is fixedly connected to the bottom end of one of the mounting seats.

[0011] The deformable radial component includes a plurality of first transmission components that are slidably connected to the radial direction of the main shaft. Each of the first transmission components is slidably connected to each other in pairs, so that each of the first transmission components forms a variable regular polygonal structure.

[0012] It also includes multiple locking components that are slidably connected to the frame. Each locking component is configured to correspond one-to-one with each mounting base, and the locking component is used to lock and limit the mounting base configured to it.

[0013] The locking element includes a rack slidably connected to the frame, and the rack is connected to the frame by a first spring.

[0014] Each mounting base has a corresponding limiting tooth fixedly connected at the position of each rack.

[0015] Each of the gears to be processed and the gear hobbing cutter is coaxially provided with a sleeve shaft, which is sleeved on the pressure elastic element.

[0016] Beneficial effects In the above technical solution, the present invention provides a multi-station gear processing equipment. This invention, by setting a coaxially arranged decoupling component between the hobbing cutter and the transmission assembly, allows the transmission relationship between the hobbing cutter and the transmission assembly to switch according to the radial position change of the deformable radial component, thereby achieving adjustable power transmission paths under different working conditions. The rotational motion of the hobbing cutter can be used to drive the support assembly for feed adjustment during the workpiece positioning stage, and the transmission connection with the transmission assembly is decoupled during the tooth profile processing stage, thereby reducing the interference of the workpiece feed motion on the hobbing cutter's cutting motion and achieving coordinated matching of motion requirements under different processing stages. Simultaneously, since the decoupling component is coaxially arranged with the hobbing cutter, power transmission occurs along the axial direction, which helps reduce the impact of off-center loads and additional torques on the transmission system, thus improving the stability of the transmission process. The radial movement of the deformable radial component achieves transmission connection and separation. Compared to multi-stage clutches or complex intermittent transmission structures, this reduces intermediate transmission links, simplifies the overall structure, and improves the reliability of transmission state switching, thereby improving motion coordination and processing stability during gear processing while ensuring structural simplicity.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Reference Figure 1 As shown in Figure 9, the present invention provides a multi-station gear processing equipment, including a frame 1 and a hobbing cutter 1.1 rotatably connected to the frame 1, and further including: a support assembly for mounting the gear to be processed 1.20; which is slidably connected to the frame 1 and is located in the radial direction of the hobbing cutter 1.1; Transmission assembly: It is located between the support assembly and the gear hobbing cutter 1.1 and is used to drive the movement of the support assembly; Decoupling component: It is set between the gear hobbing cutter 1.1 and the transmission component, and is coaxial with the gear hobbing cutter 1.1; Decoupling component: a deformable radial component 1.5 coaxially arranged with the hobbing cutter 1.1, wherein the deformable radial component 1.5 is coupled with the hobbing cutter 1.1 and the transmission component simultaneously in the first position, so that the hobbing cutter 1.1 and the transmission component are in a transmission connection state; The deformable radial component 1.5 is separated from the transmission assembly in the second position, so that the hobbing cutter 1.1 is in a non-transmission connection state with the transmission assembly; In use, when the decoupling component is in the first position, the drive transmission component drives the support component to move so that the gear 1.20 to be processed is in contact with the hobbing cutter 1.1. At this time, by adjusting the rotation speed of the hobbing cutter 1.1, the decoupling component is moved to the second position, so that the hobbing cutter 1.1 can rotate independently to process the gear 1.20 to be processed.

[0024] Specifically, the device includes a frame 1 and a hobbing cutter 1.1 rotatably connected to the frame 1. The hobbing cutter 1.1 is rotatably connected to the frame 1 via a spindle 1.10. The spindle 1.10 is driven to rotate by a drive source, which can be a servo motor 2 with active transmission, a stepper motor, a hydraulic drive, or a pneumatic drive. In this embodiment, the drive source is preferably a servo motor 2. The spindle 1.10 and the output shaft of the servo motor 2 are coaxially and fixedly connected. The servo motor 2 is mounted on the frame 1 and is used to drive the spindle 1.10 and the hobbing cutter 1.1 to rotate around their own axis. The device also includes a support assembly, a transmission assembly, and a decoupling assembly.

[0025] The support assembly is used to mount the gear 1.20 to be processed. The support assembly is coaxially rotatably connected to the gear 1.20, so that during the processing of the gear 1.20 by the hobbing cutter 1.1, the gear 1.20 can be passively rotated under the drive of the hobbing cutter 1.1. The support assembly is slidably connected to the frame 1 and located in the radial direction of the hobbing cutter 1.1, so that the gear 1.20 can move towards or away from the hobbing cutter 1.1 under the drive of the support assembly, thereby adjusting the relative position between the gear 1.20 and the hobbing cutter 1.1 to accommodate processing requirements with different pitch circle diameters.

[0026] To enable multi-station machining, multiple support components can be configured, arranged in a circular array around the gear hobbing cutter 1.1. Each support component can be equipped with a gear 1.20 to be machined, thus enabling the equipment to machine multiple gears 1.20 in a single clamping or single cycle, improving the equipment's machining efficiency and station utilization. In some embodiments, the support components can be evenly distributed along the circumference of the frame 1; in other embodiments, the support components can be non-uniformly arranged according to the functional requirements of the workstations, for example, corresponding to the loading station, tool setting station, gear hobbing station, and unloading station respectively.

[0027] Furthermore, the support assembly may include a mounting base 1.2 and a clamping part disposed on the mounting base 1.2, the clamping part being used to mount and position the gear 1.20 to be processed. The mounting base 1.2 is slidably connected to the frame 1, and the clamping part is coaxially arranged with the gear 1.20 to be processed. The clamping part may be a mandrel, chuck, expansion sleeve, positioning shaft, or other structures capable of positioning and mounting the gear. In this embodiment, the gear 1.20 to be processed can rotate relative to the clamping part after installation to meet the requirement that the workpiece rotates synchronously with the hobbing cutter 1.1 during the hobbing process.

[0028] A transmission assembly is positioned between the support assembly and the hobbing cutter 1.1 to drive the movement of the support assembly. The transmission assembly includes a transmission component, which transmits power to the support assembly, thereby causing the mounting base 1.2 to slide radially along the hobbing cutter 1.1. This enables the gear 1.20 to be processed to move radially relative to the hobbing cutter 1.1, gradually approaching and reaching the engagement position, thus providing the necessary conditions for subsequent hobbing operations.

[0029] The transmission component is a mechanism that converts rotary or oscillating motion into linear motion. It can be a lead screw and nut mechanism, a gear and rack mechanism, a crank and rocker mechanism, a cam and connecting rod mechanism, or other transmission structures that can achieve linear feed. All of the above structures are applicable to this invention.

[0030] A decoupling component is disposed between the hobbing cutter 1.1 and the transmission component, and is coaxially arranged with the hobbing cutter 1.1. The decoupling component includes the hobbing cutter 1.1, the transmission component, and a deformable radial component 1.5 disposed between them. The hobbing cutter 1.1 is fixedly connected to either the hobbing cutter 1.1 or the spindle 1.10, and the transmission components are connected to each other. The hobbing cutter 1.1 and the transmission component are coaxially arranged, and selective transmission connection is achieved between them through the deformable radial component 1.5. The deformable radial component 1.5 has radial deformation capability, used to achieve selective coupling or decoupling between the hobbing cutter 1.1 and the transmission component under different working conditions.

[0031] When the deformable radial component 1.5 is in the first position, it simultaneously engages with the hobbing cutter 1.1 and the transmission assembly, thereby establishing a transmission relationship between the hobbing cutter 1.1 and the transmission assembly. At this time, the hobbing cutter 1.1 and the transmission assembly are in a transmission connection state. In other words, in this state, the hobbing cutter 1.1 and the transmission assembly maintain synchronous association, and when the support assembly moves under the drive of the transmission assembly, the decoupling component is in a coupled state.

[0032] When the deformable radial component 1.5 is in the second position, the deformable radial component 1.5 is disengaged from the transmission assembly, thereby interrupting the transmission relationship between the hobbing cutter 1.1 and the transmission assembly. At this time, the hobbing cutter 1.1 and the transmission assembly are in a non-transmission connection state. The hobbing cutter 1.1 can rotate independently for cutting under the drive of the servo motor 2, and the transmission assembly no longer forms a linkage constraint on it.

[0033] Furthermore, the deformable radial component 1.5 can adopt a ring spring structure, a wave spring structure, an elastic retaining ring structure, a segmented elastic sleeve structure, or other structures capable of radial elastic deformation. All of the above structures are applicable to this invention. In a preferred embodiment, the deformable radial component 1.5 adopts a wave spring structure. The hobbing cutter 1.1 and the transmission assembly are respectively provided with engaging portions that cooperate with it. When the deformable radial component 1.5 is in the first position, it is simultaneously engaged within the engaging portions of the hobbing cutter 1.1 and the transmission assembly, thereby forming a stable coupling. When the rotational speed of the hobbing cutter 1.1 increases to a preset value, the deformable radial component 1.5 generates radial displacement under the combined action of centrifugal force, structural guidance, and its own elastic deformation, and disengages from the transmission assembly, thus achieving decoupling.

[0034] Furthermore, the decoupling assembly may also include a limiting structure and a reset structure. The limiting structure limits the deformation and travel of the deformable radial component 1.5 to prevent excessive deformation of the deformable radial component 1.5, which could affect its service life and decoupling stability. The reset structure, after the hobbing cutter 1.1's speed decreases or the equipment stops, causes the deformable radial component 1.5 to spring back to its first position, so that the transmission relationship between the hobbing cutter 1.1 and the transmission assembly can be re-established in the next cycle. The reset structure may be a spring-loaded reset component, an elastic pusher, a magnetic reset component, or other structures capable of providing elastic restoring force.

[0035] In operation, the gear 1.20 to be processed is first mounted on the support assembly. Initially, the decoupling assembly is in the first position, where the hobbing cutter 1.1 and the transmission assembly are coupled, maintaining a transmission connection. Then, the transmission assembly is activated, driving the support assembly to move along the frame 1 towards the hobbing cutter 1.1, gradually bringing the gear 1.20 closer to the hobbing cutter 1.1 and achieving a contact state or a preset meshing position. After contact is achieved, the rotational speed of the hobbing cutter 1.1 is adjusted. When the hobbing cutter 1.1 reaches the preset switching condition, the deformable radial component 1.5 switches from the first position to the second position under centrifugal effect, structural guidance, and its own elastic deformation, disengaging from the transmission assembly, thus releasing the transmission connection between the hobbing cutter 1.1 and the transmission assembly. Afterward, the hobbing cutter 1.1 rotates independently under the drive of the servo motor 2, performing hobbing on the gear 1.20. After processing, as the speed of the hobbing cutter 1.1 decreases or the equipment stops, the deformable radial part 1.5 returns to its first position under the action of the reset structure, so as to enter the next cycle of bonding feed and processing.

[0036] In another embodiment of the present invention, the support assembly includes a plurality of mounting seats 1.2 slidably connected to the frame 1. Each mounting seat 1.2 is coaxially arranged with the spindle 1.10, and a pressure elastic element 1.3 is provided between each mounting seat 1.2 and the spindle 1.10. The pressure elastic element 1.3 is used to buffer the gear 1.20 to be processed during tool setting to avoid the hobbing cutter 1.1 from colliding.

[0037] The pressure elastic element 1.3 includes a central shaft, and multiple second transmission elements 1.24 are slidably connected to the radial direction of the central shaft. Each second transmission element 1.24 is slidably connected in pairs, and each second transmission element 1.24 is connected to the central shaft by a second spring 1.270.

[0038] Each mounting base 1.2 is provided with a telescopic member 1.23 in the radial direction. The telescopic member 1.23 is used to connect two adjacent mounting bases 1.2.

[0039] Each gear 1.20 to be processed and the hobbing cutter 1.1 are coaxially provided with a sleeve 1.111, which is sleeved on the pressure elastic element 1.3.

[0040] Specifically, the support assembly includes multiple mounting seats 1.2 slidably connected to the frame 1. Each mounting seat 1.2 is coaxially arranged with the spindle 1.10, and a pressure elastic element 1.3 is provided between each mounting seat 1.2 and the spindle 1.10. The pressure elastic element 1.3 is used to provide elastic buffering during the tool setting process of the gear 1.20 to be machined, so as to avoid rigid collision between the gear 1.20 to be machined and the hobbing cutter 1.1, thereby reducing the risk of the hobbing cutter 1.1 colliding and improving the safety and stability of the tool setting process.

[0041] The pressure elastic element 1.3 includes a central shaft, to which multiple second transmission elements 1.24 are slidably connected in the radial direction. Each second transmission element 1.24 is slidably connected in pairs, and each second transmission element 1.24 is connected to the central shaft via a second spring 1.270. Each second transmission element 1.24 can move relative to the central shaft in the radial direction under the action of an external force and return to its original position under the elastic action of the second spring 1.270. This gives the pressure elastic element 1.3 radial elastic deformation capability, which serves as a buffer during tool setting.

[0042] Each mounting base 1.2 is provided with a telescopic component 1.23 in the radial direction, and two adjacent mounting bases 1.2 are connected by the telescopic component 1.23. By setting the telescopic component 1.23, not only can the relative relationship between multiple mounting bases 1.2 be maintained, but also an adaptive connection can be provided during the radial movement of each mounting base 1.2, so as to improve the structural stability when multiple mounting bases 1.2 are adjusted in a coordinated manner.

[0043] Each gear 1.20 and hobbing cutter 1.1 is coaxially fitted with a sleeve 1.111, which is sleeved on the outside of the pressure elastic element 1.3. The sleeve 1.111 is used to connect with the gear 1.20 or the hobbing cutter 1.1 so that the gear 1.20 and the hobbing cutter 1.1 can respectively form an assembly relationship with the pressure elastic element 1.3. The sleeve 1.111 and the hobbing cutter 1.1 can be fixedly connected or detachably connected, and the sleeve 1.111 and the gear 1.20 are preferably detachably connected. The detachable connection can be a plug-in connection, a threaded connection, a snap-fit ​​connection, or other connection methods that are easy to install and remove, so as to facilitate the replacement of the gear 1.20 and equipment maintenance.

[0044] The frame 1 has multiple first waist-shaped grooves at radial positions along the main shaft 1.10, which are adapted to the mounting seats 1.2. Each mounting seat 1.2 is slidably disposed in its respective first waist-shaped groove. Each mounting seat 1.2 is coaxially rotatably connected to a central shaft, and the mounting seats 1.2 are connected in pairs by telescopic members 1.23, so that the multiple mounting seats 1.2 can maintain mutual cooperation when moving in the radial direction.

[0045] A central shaft is coaxially fixedly connected to the main spindle 1.10. A sleeve 1.111 is coaxially fixedly connected to the ends of each gear 1.20 and hobbing cutter 1.1, and the sleeve 1.111 is fitted onto the outside of the pressure elastic element 1.3. When the gear 1.20 to be processed moves towards the hobbing cutter 1.1 under the drive of the mounting base 1.2 and is being set, the pressure elastic element 1.3 can undergo elastic deformation in the radial direction, thereby absorbing part of the impact load and preventing rigid collision between the hobbing cutter 1.1 and the gear 1.20 to be processed.

[0046] Multiple second limiting grooves 1.27, adapted to the second transmission components 1.24, are radially formed on the central shaft. Each second transmission component 1.24 is slidably connected within its corresponding second limiting groove 1.27. A second spring 1.270 is installed within each second limiting groove 1.27, with one end connected to the second limiting groove 1.27 and the other end fixedly connected to the corresponding second transmission component 1.24. The opposite ends of each second transmission component 1.24 are slidably connected to each other. Under external force, each second transmission component 1.24 can move radially along its corresponding second limiting groove 1.27, compressing the corresponding second spring 1.270. When the external force is released, under the restoring force of the second spring 1.270, each second transmission component 1.24 returns to its initial position, thus realizing the elastic buffering and automatic reset function of the pressure elastic component 1.3.

[0047] In another embodiment of the present invention, the transmission assembly includes a drive disk 1.6 coaxially arranged with the deformable radial member 1.5, a transmission groove 1.60 is formed on the drive disk 1.6, and a transmission column 1.22 adapted to the transmission groove 1.60 is fixedly connected to the bottom end of one of the mounting seats 1.2.

[0048] The deformable radial component 1.5 includes a plurality of first transmission components 1.101 that are slidably connected to the radial direction of the main shaft 1.10. Each first transmission component 1.101 is slidably connected to each other in pairs, so that each first transmission component 1.101 forms a variable regular polygonal structure.

[0049] It also includes multiple locking components that are slidably connected to the frame 1. Each locking component is configured to correspond one-to-one with each mounting base 1.2, and the locking components are used to lock and limit the mounting base 1.2 configured to them.

[0050] The locking element includes a rack 1.26 that is slidably connected to the frame 1, and the rack 1.26 is connected to the frame 1 by a first spring 1.250.

[0051] Each mounting base 1.2 has a corresponding limiting tooth 1.25 fixedly connected at the position of each rack 1.26.

[0052] Specifically, two second waist-shaped grooves are formed on both sides of each first waist-shaped groove on the frame 1, and each second waist-shaped groove extends radially along the mounting base 1.2. Each rack 1.26 slides into its corresponding second waist-shaped groove, allowing the rack 1.26 to move radially along the mounting base 1.2. Each second waist-shaped groove is equipped with a first spring 1.250, one end of which is fixedly connected to the corresponding rack 1.26, and the other end is fixedly connected to the inner wall of the second waist-shaped groove. The rack 1.26, under the elastic action of the first spring 1.250, tends to move towards a predetermined locking position, thus enabling it to engage or lock with the limiting teeth 1.25 on the mounting base 1.2 when the mounting base 1.2 moves to the preset position, thereby locking and limiting the mounting base 1.2. When the mounting base 1.2 needs to be released and continue moving, the rack 1.26 can overcome the elastic force of the first spring 1.250 under the action of external force and slide along the second waist-shaped groove, thereby exiting the locking position. This not only improves the positioning stability of the mounting base 1.2 when it stops at each position, but also prevents unexpected displacement of the mounting base 1.2 during processing.

[0053] The main shaft 1.10 has multiple first limiting grooves 1.102 adapted to the first transmission components 1.101 in the radial direction. Each first transmission component 1.101 is slidably disposed in its corresponding first limiting groove 1.102. A tension spring 1.103 is fixedly connected to the inner wall of each first limiting groove 1.102, and the other end of each tension spring 1.103 is fixedly connected to the corresponding first transmission component 1.101. The opposite ends of each first transmission component 1.101 are slidably connected to each other, so that the multiple first transmission components 1.101 can be enclosed to form a variable regular polygonal structure. Each first transmission component 1.101 can move relative to each other in the radial direction of the main shaft 1.10 under the combined action of centrifugal force and the restoring force of the tension spring 1.103, thereby changing the outer contour dimensions of the variable regular polygonal structure, so as to realize the coupling or separation of the deformable radial component 1.5 in different working states.

[0054] A drive disk 1.6 is sleeved on the main shaft 1.10 outside the first transmission component 1.101. A mating hole adapted to the variable regular polygonal structure is opened at the shaft center of the drive disk 1.6. The shape of the mating hole corresponds to the outer contour formed by the first transmission member 1.101, so that when the variable regular polygonal structure expands radially to a preset size, the first transmission member 1.101 can form a stable fit with the mating hole of the drive disk 1.6, thereby establishing a transmission connection between the deformable radial member 1.5 and the drive disk 1.6; when the variable regular polygonal structure contracts radially, the first transmission member 1.101 disengages from the mating hole, thereby releasing the transmission connection between the deformable radial member 1.5 and the drive disk 1.6. A transmission groove 1.60 is provided in the drive disk 1.6, and a transmission column 1.22 adapted to the transmission groove 1.60 is fixedly connected to the bottom end of one of the mounting seats 1.2. When the transmission column 1.22 slides in the transmission groove 1.60, it drives each mounting seat 1.2 to slide relative to each other in the radial direction of the hobbing cutter 1.1.

[0055] By adjusting the speed of the servo motor 2, the coupling and decoupling states between the deformable radial component 1.5 and the drive disk 1.6 are switched. Specifically, the servo motor 2 is set to operate in different states at a first speed V1 and a second speed V2, where V1 > V2. When the speed of the servo motor 2 is V1, the spindle 1.10 drives the first transmission component 1.101 to rotate at high speed. Under the action of centrifugal force, each of the first transmission components 1.101 moves along the first limiting groove 1.102 away from the axis of the spindle 1.10, while the tension spring 1.103 is stretched. As each of the first transmission components 1.101 opens outward, the outer contour of the variable regular polygonal structure formed by the multiple first transmission components 1.101 increases and matches the mating hole at the axis of the drive disk 1.6, thereby putting the deformable radial component 1.5 and the drive disk 1.6 in a coupled state.

[0056] When the speed of the servo motor 2 decreases from V1 to V2, the centrifugal force on each of the first transmission components 1.101 decreases, and the restoring force of the tension spring 1.103 gradually becomes dominant, thereby pulling each of the first transmission components 1.101 back along the first limiting groove 1.102 towards the axis of the main shaft 1.10. As each of the first transmission components 1.101 retracts inward, the outer contour dimension of the variable regular polygonal structure decreases, and it gradually disengages from the mating hole at the axis of the drive disk 1.6, causing the deformable radial component 1.5 to disengage from the drive disk 1.6. At this time, the deformable radial component 1.5 and the drive disk 1.6 are in a separated state, the transmission relationship between the hobbing cutter 1.1 and the transmission assembly is interrupted, and the decoupling assembly is in a non-transmission connection state. After this, the hobbing cutter 1.1 can rotate independently under the drive of the servo motor 2 to perform hobbing on the gear 1.20 to be machined.

[0057] The first limiting groove 1.102 is used not only to limit the radial movement trajectory of the first transmission component 1.101, but also to limit the maximum opening of the first transmission component 1.101, so as to prevent the first transmission component 1.101 from detaching from the main shaft 1.10 or affecting the transmission stability due to excessive outward expansion during high-speed rotation. The tension spring 1.103, in addition to driving the first transmission component 1.101 to reset at low speeds, also provides a stable restoring force during the process of the first transmission component 1.101 switching from a coupled state to a disengaged state, thereby improving the reliability and repeatability of the decoupling action.

[0058] The drive disk 1.6 is fixedly connected to the transmission assembly. The mating holes on the drive disk 1.6 are regular polygonal holes or approximately regular polygonal holes that match the variable regular polygonal structure. The first transmission component 1.101 is preferably a plate-shaped transmission block, a wedge-shaped transmission block, or an arc-shaped transmission block. By setting the shape, quantity, and mutual sliding fit relationship of the first transmission component 1.101, the structural parameters of the deformable radial component 1.5 can be adjusted according to the coupling force, switching speed, and processing stability required by the equipment.

[0059] In actual use, when the gear to be processed 1.20 approaches the hobbing cutter 1.1 and completes contact under the drive of the support component, the speed of the servo motor 2 can be switched from the first speed V1 to the second speed V2 to separate the deformable radial component 1.5 from the drive disk 1.6, thereby releasing the linkage between the hobbing cutter 1.1 and the transmission component. After processing is completed, the speed of the servo motor 2 is adjusted to make each of the first transmission components 1.101 open outward again under the action of centrifugal force, and re-establish the transmission connection with the drive disk 1.6, thus providing a basis for the next cycle of feeding and processing.

[0060] During use, the servo motor 2 is rotated to a speed of V1 and rotated to a preset angle. The second transmission components 1.24 on the deformable radial component 1.5 are coupled with the drive disk 1.6, causing the drive disk 1.6 to rotate. This causes the transmission column 1.22 to rotate within the transmission groove 1.60 of the drive disk 1.6, which in turn causes the gears 1.20 to be processed on each mounting base 1.2 to move toward the hobbing cutter 1.1 until the circumference of the hobbing cutter 1.1 contacts the gears 1.20. During the contact process, the pressure elastic component 1.3 provides buffering to prevent the gears to be processed from colliding with the hobbing cutter 1.1 during tool setting. At this time, the locking component limits the mounting base 1.2. Then, when the servo motor 2 rotates to a speed of V2, the deformable radial component 1.5 is disengaged from the drive disk 1.6, allowing the hobbing cutter 1.1 to process the gears.

[0061] 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.
