Description
Technical Field
[0001] This invention relates to the field of gear processing technology, and more specifically to a gear hobbing machine for gear processing. Background Technology
[0002] In mechanical transmission systems, gears play a crucial role in power transmission and speed change, and their performance and lifespan directly affect the reliability of the equipment. During gear machining using a gear hobbing machine, after the gears are cut by the hob, a large amount of cutting fluid, metal cutting debris, machining burrs, polishing or grinding waste remains on the tooth surface and root. These residues not only compromise the meshing accuracy of the gear teeth and increase wear noise, but can also cause pitting, spalling, and scuffing failures. Industry data shows that over 30% of gearbox failures are related to lubrication contamination and machining residues. Therefore, efficient and thorough deburring and chip removal have become core process steps to ensure gear accuracy, long service life, and equipment stability.
[0003] Traditional gear cleaning methods have drawbacks. Simple manual or soaking cleaning is inefficient and cannot completely remove impurities adhering to the gear surface. Although ultrasonic cleaning improves cleanliness, it is not very effective for cleaning large gears and the equipment is expensive.
[0004] Chinese patent application CN115921392A discloses a gear cleaning device and method, comprising: a liquid supply mechanism for providing cleaning liquid; a cleaning mechanism for cleaning gears; and a fixing mechanism comprising: a frame having a receiving cavity with multiple grooves on the cavity wall; a circular tube having one end rotatably inserted through the frame and the other end extending into the receiving cavity for mounting multiple gears to be cleaned; multiple sliders respectively disposed in corresponding grooves, the sliders being connected to a stop bar for separating adjacent gears; an insert rod slidably inserted through the frame and into the circular tube; and a first driving member for driving the circular tube to rotate. The gear cleaning device can clean multiple gears simultaneously.
[0005] Existing gear hobbing technologies have drawbacks. Traditional gear hobbing machines focus only on the cutting process, and the deburring and deep cleaning processes after machining often require manual unloading and simple manual or soaking cleaning, which is inefficient and makes it difficult to completely remove iron filings adhering to the gear surface; or expensive dedicated deburring machines are required. Therefore, there is an urgent need in this field for a gear hobbing machine accessory that integrates a highly efficient deburring and chip removal system. Summary of the Invention
[0006] This invention provides a gear hobbing machine for gear processing, aiming to solve the problem that in related technologies, gear hobbing machines only focus on the cutting process. For the deburring and deep cleaning stages after processing, manual unloading and simple manual or soaking cleaning are often required, which is inefficient and makes it difficult to completely remove iron filings adhering to the gear surface.
[0007] A gear hobbing machine for gear processing includes: a housing, a processing assembly, and a control console. The housing houses a cooling assembly, an auxiliary clamping assembly, and a deburring assembly. The auxiliary clamping assembly includes an annular support frame and multiple sliding seats. The support frame is rotatably mounted within the housing. The multiple sliding seats are mounted on the support frame around its rotation axis, with the sliding seats diametrically close to or away from the support frame's rotation axis. The deburring assembly includes multiple deburring brushes, which are equally spaced on the support frame around its axis. A rotating wheel and a scraper are vertically mounted on each sliding seat. The upper end face of the deburring brush protrudes from the support frame, and the side of the scraper closest to the support frame's rotation axis protrudes from the rotating wheel. During operation, the cooling assembly flushes the gear with high-pressure cutting fluid, the deburring brushes abut against the lower side of the gear, the rotating wheel abuts against the gear's sidewall, and the drive assembly is mounted on the support frame to rigidly position the gear and drive it to rotate on the support frame.
[0008] Its effects are as follows: This invention, by setting up a housing, processing components, control console, cooling components, auxiliary clamping components, and deburring components, forms an integrated gear cleaning and deburring system, greatly improving the processing efficiency and quality after gear machining. First, it solves the problem of difficult post-machining gear cleaning. Traditional cleaning methods often fail to thoroughly remove stubborn oil stains and cutting debris from the gear surface. This invention utilizes the annular support frame in the auxiliary clamping component, combined with a radially moving sliding seat, to flexibly adapt to clamping gears of different diameters, eliminating the need for repeated manual handling or flipping. Second, it achieves multi-dimensional deep cleaning. The deburring component adopts a unique layout; the deburring brush inside the housing can directly contact the underside of the gear, effectively cleaning stubborn impurities and edge burrs on the gear's bottom surface. Simultaneously, the vertically arranged scraper strips on the sliding seat adhere closely to the gear sidewall (or tooth groove), mechanically scraping away highly adhesive metal debris during gear rotation. Combined with the high-pressure cutting fluid from the cooling component for all-around rinsing, it achieves a dual cleaning effect of "mechanical scraping and fluid rinsing," solving the problem that simple water washing cannot remove stubborn stains. Rapid cleaning after machining effectively prevents the splashing of cutting fluid and debris, avoiding secondary pollution of the workshop environment. The automated control system at the control console reduces manual intervention, lowers worker workload and safety risks, and significantly extends the service life of gears and subsequent equipment.
[0009] Preferably, the support frame is provided with multiple sets of bearing wheels, which are equally spaced around the rotation axis of the support frame. The bearing wheels rotate around the diameter of the support frame, and each set of bearing wheels has multiple bearing wheels along the diameter direction of the support frame.
[0010] The effect is as follows: by arranging multiple sets of bearing wheels at equal intervals along the diameter on the support frame, and with these bearing wheels capable of rotating around the diameter, this design reduces the frictional resistance of the gears when rotating on the support frame. The multiple sets of bearing wheels form a stable support plane, ensuring the levelness of the gears during cleaning and preventing tilting or swaying due to gravity. Furthermore, rolling friction replaces sliding friction, resulting in smoother and more energy-efficient rotation of the gears by the drive assembly, while also protecting the bottom surface of the gears from scratches.
[0011] Preferably, the sliding seat is provided with multiple rotating wheels, which are symmetrically arranged on both sides of the scraper bar, and the multiple bearing wheels arranged at equal intervals simultaneously abut against multiple teeth.
[0012] Its effect lies in the fact that multiple rotating wheels symmetrically arranged on both sides of the scraper bar on the sliding seat, along with equally spaced bearing wheels, together form a stable multi-point contact structure. This symmetrical layout effectively disperses the contact stress between the gears and the clamps, preventing excessive force at a single point from damaging the tooth surface or overloading a single tooth. When multiple rotating wheels simultaneously abut against multiple teeth, the stability of the gears during rotation is greatly improved, avoiding gear slippage, displacement, or vibration caused by water flow impact or mechanical scraping force during cleaning, thus ensuring the continuity and uniformity of the cleaning operation.
[0013] Preferably, the support frame is provided with a guide groove, and the lower end of the sliding seat is provided with a guide block. The guide groove is provided along the diameter direction of the support frame, and the guide block cooperates with the guide groove to make the sliding seat slide along the diameter direction of the support frame.
[0014] The effect is that the guide groove on the support frame cooperates with the guide block at the lower end of the sliding seat (preferably a T-shaped or dovetail structure), providing precise linear guidance for the radial movement of the sliding seat. This structural design enhances the rigidity of the auxiliary clamping assembly, ensuring that the sliding seat will not deflect or derail when adjusting the clamping position of gears of different diameters. It also improves the smoothness of adjustment, ensuring that each sliding seat can accurately and synchronously approach or move away from the center of the support frame, thereby achieving rapid and accurate alignment of the gears.
[0015] Preferably, the support frame is provided with multiple mounting slots, which are equally spaced around the rotation axis of the support frame on one side of the guide slot. The mounting slots are arranged along the diameter direction of the support frame. Multiple burr brushes are movably arranged in the mounting slots. The plane formed by the upper end surfaces of multiple bearing wheels is located between the burr brushes and the support frame.
[0016] The effect is as follows: A mounting slot is provided on the support frame, in which the burr brush is movably positioned, and the upper surface of the support wheel is positioned between the burr brush and the support frame—this height difference design is crucial. It ensures that the main weight of the gear is borne by the support wheel (achieving low-friction rotation), while the burr brush only contacts the bottom surface of the gear with appropriate pressure for cleaning. This prevents the burr brush from excessively wearing or deforming due to excessive weight, and also ensures that the bristles can effectively reach the uneven areas at the bottom of the gear, achieving a reasonable separation and coordination between the support and cleaning functions.
[0017] Preferably, the cooling assembly includes: a first cooling pipe and a second cooling pipe, the first cooling pipe being disposed inside the housing, and the second cooling pipe being disposed vertically inside the housing.
[0018] The effect is as follows: the cooling assembly uses a combination of horizontally arranged cooling pipe 1 and vertically arranged cooling pipe 2, creating a three-dimensional spray network. Cooling pipe 1 is mainly responsible for rinsing the bottom of the gear, working in conjunction with a deburring brush to remove dirt from the bottom surface; cooling pipe 2 rinses the gear from the side or vertical direction. This multi-angle fluid coverage ensures that the cleaning fluid can enter every dead corner of the gear, such as the tooth root and shaft hole, greatly improving the cleaning coverage and ensuring no blind spots in cleaning.
[0019] Preferably, the processing assembly includes a vertically arranged processing head, which is telescopically mounted on the processing assembly, and the processing assembly can be adjusted up and down to allow the processing head to process the gear.
[0020] Its advantages are as follows: the machining assembly uses a vertically positioned machining head with telescopic and height-adjustable functions, which can flexibly adapt to the machining needs of gears with different modules, numbers of teeth, and thicknesses. The telescopic design of the machining head can precisely control the cutting feed rate and ensure the machining accuracy of the tooth profile; while the height-adjustable machining assembly allows machining at different axial positions of the gear, improving the versatility of the equipment.
[0021] Preferably, a flexible buffer sleeve is fitted onto the rotating wheel.
[0022] Its effect is as follows: A flexible buffer sleeve (such as one made of rubber) is fitted onto the rotating wheel, providing both protection and friction enhancement. First, the flexible material directly contacts the gear teeth, avoiding rigid collisions between hard metals and effectively preventing scratches on the delicate gear surface during cleaning. Second, the flexible sleeve (especially the design with petal-shaped protrusions) increases the coefficient of friction between the rotating wheel and the gear, ensuring effective transmission of driving force, preventing slippage, and guaranteeing that the gear can rotate stably with the drive assembly.
[0023] Preferably, the burr brush is slidably installed along the mounting groove, and a limit bolt is provided on the side wall of the mounting groove.
[0024] The advantages are as follows: the bristle brush's sliding installation within the mounting slot, coupled with a limiting bolt, provides the cleaning component with excellent maintenance convenience and lifespan management capabilities. Over time, the bristles will wear and shorten; by loosening the limiting bolt and adjusting the bristle brush's height upwards, the amount of wear can be compensated, ensuring the bristles maintain optimal contact pressure with the gear's bottom surface, thus guaranteeing consistent cleaning results. Simultaneously, this detachable structure facilitates quick replacement when the bristles are completely worn out.
[0025] Preferably, the drive assembly includes a drive source and a drive block, the drive block being vertically arranged to drive the gear to rotate, and the drive source being used to make the drive block rotate.
[0026] Its effect is as follows: the drive assembly includes a drive source and a vertically positioned drive block, providing active rotational power for the gear cleaning. The drive block drives the gear to rotate at a uniform speed on the support frame, allowing the stationary nozzle and scraper to move relative to the gear, thus traversing every tooth and every inch of the gear's surface. This automated rotational drive replaces manual rotation, ensuring not only uniform cleaning (avoiding the arbitrariness of human operation) but also significantly improving cleaning efficiency, serving as the core power guarantee for achieving fully automated cleaning operations.
[0027] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. This invention integrates three cleaning methods: high-pressure rinsing (cooling components), bottom brushing (burr brush), and side scraping (scraper strips). This combined "rinsing, brushing, and scraping" mechanism not only removes surface oil but also effectively removes stubborn impurities and burrs from the gear surface, tooth roots, and edges. Combined with the automatic rotation of the gears, it solves the problems of difficult cleaning of large gears, the need for manual turning, and the easy retention of cleaning dead corners.
[0028] 2. With radially adjustable auxiliary clamping components, the equipment can adapt to gears of different diameters, making it highly versatile. Simultaneously, the design employs multiple sets of load-bearing wheels and rotating wheels with flexible buffer sleeves. This utilizes rolling friction to ensure the smooth rotation of the gears during the cleaning process, while also preventing scratches on the precision tooth surfaces caused by rigid contact, effectively extending the service life of both the gears and the equipment.

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0039] When hobbing a gear, the gear to be processed is placed on the auxiliary clamping assembly 3 and positioned using the auxiliary clamping assembly 3. After positioning, the drive assembly 5 adjusts the gear rotation to process the gear. During the gear processing, the cooling assembly 2 sprays coolant to cool the gear. After processing, the drive assembly 5 drives the gear to perform surface cleaning.
[0040] like Figures 1 to 8As shown, a gear hobbing machine for gear processing includes: a housing 11, a processing component 12, and a control console 13. The housing 11 houses a cooling component 2, an auxiliary clamping component 3, and a deburring component 4. The auxiliary clamping component 3 is located inside the housing 11 and is placed on the auxiliary clamping component 3 when cleaning the processed gear. The deburring component 4 is located inside the housing 11 and removes stubborn impurities and burrs from the gear surface during cleaning. The cooling component 2 is located inside the housing 11 and washes the surface of the gear during cleaning, removing impurities. During gear cleaning, the processing component 12 stops processing the gear, and the gear to be cleaned is placed on the auxiliary clamping component 3. The drive component 5 controls the drive block 51 to rotate the gear. The cleaning of the gear is controlled by the control console 13 located outside the housing 11.
[0041] The cooling component 2 and the deburring component 4 work together, and the control console 13 located on the outside of the housing 11 is used for operation. No manual adjustment is required during the cleaning process. The high-pressure water flow of the cooling component 2 covers the gear tooth grooves and shaft holes, effectively removing cutting oil residue and metal shavings, avoiding secondary pollution. The auxiliary clamping component 3 works with the deburring component 4 to clean the gears. The gears are rotated by the drive component 5. No gear adjustment is required during the cleaning process, which reduces the difficulty of cleaning and improves the cleaning effect.
[0042] like Figures 3 to 8 As shown, the auxiliary clamping assembly 3 includes: a support frame 31, a sliding seat 32, and a bearing wheel 33. The support frame 31 is rotatably arranged in a ring within the housing 11. Multiple mounting grooves 313 are provided on the upper surface of the support frame 31 around the rotation axis. The mounting grooves 313 are evenly spaced and arranged along the diameter direction of the support frame 31. The mounting grooves 313 can be cut into the support frame 31 by cutting. The dimensional accuracy of the mounting grooves 313 is ensured through cutting. The sliding seat 32 is slidably arranged within the mounting groove 313, approaching or moving away from the rotation axis of the support frame 31 along the length direction of the mounting groove 313. The guide groove 311 has a T-shaped or dovetail-shaped cross-section. A matching guide block 312 is welded or integrally formed at the bottom of the sliding seat 32. A drive mechanism is provided within the mounting groove 313. The drive mechanism controls the synchronous movement of multiple sliding seats 32. Preferably, the drive mechanism is an electric telescopic rod, which is preferably a linear motor-driven electric push rod or an electric actuator with a rotary motor and a lead screw. The fixed end of the electric telescopic pole is installed in the pivot area of the support frame 31 through a hinged seat or a rigid connector, and its telescopic end is connected to all sliding seats 32 simultaneously through a linkage mechanism, such as a rigid connecting plate, a synchronous connecting rod or a wire rope synchronization system. Alternatively, multiple synchronous electric telescopic poles can be used to control them simultaneously.
[0043] When the electric telescopic pole is powered on, the linear motion of its telescopic end is converted into synchronous radial displacement of the sliding seat 32 within the corresponding mounting groove 313 via a linkage mechanism. This ensures that multiple sliding seats 32 can simultaneously move closer to or further away from the rotation center of the support frame 31, thereby achieving synchronous expansion or contraction of multiple load-bearing wheels 33. The control system of the electric telescopic pole can precisely set the telescopic stroke, ensuring the positioning accuracy of the sliding seat 32, fast action response, and easy control.
[0044] like Figures 4 to 7 As shown, the support frame 31 is equipped with multiple sets of bearing wheels 33. These sets of bearing wheels 33 are arranged at equal intervals around the rotation axis of the support frame 31 to optimize the smoothness of rotation. The bearing wheels 33 in the same group are arranged horizontally along the diameter direction of the rotating frame to ensure uniform support force during operation. The bearing wheels 33 are made of high-strength wear-resistant materials, such as rubber or composite materials, to reduce wear and improve the service life of the overall system. The rotation axis of the bearing wheel 33 is connected to the support frame 31 through bearings. The bearing wheel 33 adopts a polyurethane-coated steel core structure with anti-slip texture on its surface to ensure that the gear remains stable during rotation cleaning and does not slip relative to each other along the diameter direction.
[0045] All the bearing wheels 33 have their upper ends tangent to the same horizontal plane. The gear is placed on the bearing wheel 33, and the horizontal plane tangent to the upper end of the bearing wheel 33 is above the upper surface of the support frame 31. When the gear is placed, it is placed on the bearing wheel 33 and does not contact the upper end surface of the support frame 31. By setting multiple bearing wheels 33, the friction between the gear and the support frame 31 during cleaning is reduced. When the gear is processed, the support frame 31 drives the gear to rotate to adjust the processing position, ensuring that the gear rotates smoothly and without deviation during the processing, thereby reducing vibration.
[0046] like Figures 3 to 7 As shown, the sliding seat 32 is provided with multiple rotating wheels 43, which are symmetrically arranged on both sides of the scraper bar 44. The rotating wheels 43 are vertically arranged at the upper end of the sliding seat 32. Multiple rotating wheels 43 are evenly spaced at the upper end of the sliding seat 32. The rotating shaft at the lower end of the rotating wheel 43 is installed in the mounting hole at the top of the sliding seat 32 through the bearing assembly, so as to realize the free rotation of the rotating wheel 43 in the vertical plane. The distance between the two outermost rotating wheels 43 on a sliding seat 32 is greater than the tooth pitch between two gear teeth, so that the rotating wheel 43 on the same sliding seat 32 can simultaneously abut with at least two teeth of the gear. During processing, the rotating wheels 43 restrict the movement of the gear relative to the support frame 31 through multiple points, so as to reduce the gear offset caused by unilateral force.
[0047] This arrangement can distribute the gear contact pressure, prevent single tooth overload, reduce tooth surface wear, and improve the stability of the cleaning process. It also ensures that the sliding seat 32 remains stable during movement, avoiding slippage or deviation, thereby extending the service life of the equipment and optimizing the cleaning effect.
[0048] The scraper 44 is located at the upper end of the sliding seat 32 and between the rotating wheels 43. The scraper 44 consists of a fixed rod and a cleaning brush. The fixed rod is fixed to the upper end of the sliding seat 32 by bolts or welding. The fixed rod is made of metal. The cleaning brush is made of wear-resistant nylon material. The cleaning brush is located on the side of the fixed rod near the gear and protrudes from the outer edge of the rotating wheel 43. It is used to remove stubborn stains at the root of the gear. The cleaning brush is movably installed on the fixed rod by snap-fit or other means. The cleaning brush can be quickly replaced according to the wear condition of the cleaning brush, so that the cleaning brush can quickly return to a better cleaning state.
[0049] The cleaning brush effectively removes dirt from the gear roots, reducing gear wear and extending equipment life. Its design allows for targeted cleaning of finished gears. The movable mounting structure simplifies and speeds up replacement, significantly reducing maintenance time. Wear-resistant nylon material ensures the cleaning brush's durability, and combined with the stability of the metal mounting rod, overall cleaning reliability is improved, thereby reducing operating costs and ensuring production safety.
[0050] like Figures 4 to 7 As shown, a flexible sleeve is fitted on the rotating wheel 43. The flexible sleeve is made of rubber and has a cross-section with petal-shaped protrusions. These protrusions are designed to enhance the friction between the rotating wheel 43 and the contact surface, thereby improving rotation efficiency and stability and ensuring reliable transmission performance under various working conditions. At the same time, covering the rotating wheel 43 with a layer of rubber can reduce the stress when the gear contacts the rotating wheel 43.
[0051] like Figures 2 to 5 As shown, the support frame 31 is provided with multiple mounting slots 313. The multiple mounting slots 313 are arranged at equal intervals around the rotation axis of the support frame 31 on one side of the guide slot 311. The mounting slots 313 extend along the diameter direction of the support frame 31. Multiple burr brushes 41 are movably disposed in the mounting slots 313. The burr brushes 41 are disposed in the mounting slots 313 along the length direction of the mounting slots 313. The upper end face of the burr brushes 41 protrudes from the tangent surface of the upper end of the multiple bearing wheels 33. When the gear is cleaned, the upper end face of the burr brushes 41 keeps in contact with the gear. The burr brushes 41 are composed of a fixed rod and a cleaning brush. The fixed rod is slidably installed in the mounting slot 313. The fixed rod is made of metal. The cleaning brush is made of wear-resistant nylon material. The cleaning brush is disposed on the side of the fixed rod close to the gear. The cleaning brush protrudes from the upper surface of the bearing wheel 33 and is used to scrape off stubborn stains and processing debris from the lower side of the gear.
[0052] The side wall of the mounting groove 313 is provided with limiting bolts 314. Multiple limiting bolts 314 are arranged along the length of the mounting groove 313. After the deburring brush 41 is placed in the mounting groove 313, the height of the deburring brush 41 is adjusted so that it abuts against the lower end face of the gear to be cleaned. The limiting bolts 314 lock the deburring brush 41 in place. The movable design of the deburring brush 41 allows for adjustment of the height of its upper end face to accommodate gears of different thicknesses. When the limiting bolts 314 are tightened, the axial pressure generated at the end of the limiting bolts 314 is transmitted to the fixing rod through the wall of the mounting groove 313, generating static friction between the rod and the side wall of the mounting groove 313. This securely locks the position of the deburring brush 41, ensuring stable contact pressure between the deburring brush 41 and the lower surface of the gear during cleaning, effectively removing adhering substances. The cleaning brush also adopts a detachable design, fixed to the fixing rod by a snap-fit or threaded connection, facilitating quick replacement after wear.
[0053] like Figures 2 to 8 As shown, a processing head 14 is provided at the lower end of the processing assembly 12. A telescopic device is provided between the processing head 14 and the lower bottom surface of the processing assembly 12. The processing head 14 moves up and down to process the gear. The processing assembly 12 includes a drive motor and a lifting structure. The vertically arranged lifting structure adjusts the position of the processing head 14, and the drive motor is used to drive the processing head 14 to work.
[0054] like Figures 4 to 7 As shown, the cooling assembly 2 includes a first cooling pipe 21 and a second cooling pipe 23. The first cooling pipe 21 is horizontally arranged inside the housing 11, and multiple nozzles are provided on the upper side of the first cooling pipe 21. The nozzles on the first cooling pipe 21 rinse and cool the bottom of the gear. The second cooling pipe 23 is vertically arranged inside the housing 11 and is located outside the support frame 31. Multiple nozzles are provided on the side of the second cooling pipe 23 facing the gear, and the nozzles on the second cooling pipe 23 rinse and cool the side of the gear. The cooling assembly 2 also includes a water pump assembly externally connected to the first cooling pipe 21 and the second cooling pipe 23. The water pump assembly is used to pump water to complete the rinsing of the gear.
[0055] Both cooling pipe 21 and cooling pipe 23 are made of corrosion-resistant stainless steel, with polished inner walls to reduce fluid resistance and ensure smooth flow of high-pressure water. The nozzles feature a detachable fan-shaped design with an adjustable spray angle between 60 and 120 degrees, achieving comprehensive cleaning of the gear teeth, roots, and shaft bores. The pump assembly includes a high-pressure plunger pump, a filter, and a pressure regulating valve. The filter effectively intercepts various impurities. Each cooling pipe is connected to the main pipeline via quick-connect sealing joints, with double O-ring fluororubber seals inside the joints to ensure no leakage during operation and prevent cleaning fluid from affecting the environment and equipment safety.
[0056] like Figures 3 to 7As shown, when processing the gear, the gear is placed on the support frame 31 with the assistance of the hoisting equipment. Before being placed on the support frame 31, multiple sliding seats 32 are moved toward the rotating shaft of the support frame 31 by adjusting the electric telescopic rod. Multiple rotating wheels 43 set on the sliding seats 32 abut against the gear, moving the gear to be processed to the center position of the support frame 31. The gear to be processed is then placed on the bearing wheel 33 set on the support frame 31, and processing begins. During the processing, when the support frame 31 rotates, the gear rotates with the support frame 31. The cooling component 2 washes and cools the surface of the gear. During the processing, the support frame 31 is stopped rotating by adjusting the control console 13, and the gear also stops rotating synchronously.
[0057] During processing, the support frame 31 is stopped rotating via the control console 13, while the drive assembly 5 drives the gear to rotate. This setup significantly improves the comprehensiveness of the cleaning process. First, the gear rotation ensures that all surfaces of the gear are evenly exposed to the spray water flow, avoiding cleaning dead spots caused by fixed positions, thus improving cleaning quality and preventing debris residue. During gear rotation, the deburring assembly 4 removes stubborn stains and burrs from the gear. This design also reduces the need for manual intervention. By adjusting the sliding seat 32 and the rotating wheel 43 to center the gear, eccentric rotation prevents equipment wear or uneven cleaning. This not only shortens cleaning time and improves production line efficiency but also reduces the labor intensity and safety risks for operators, ultimately extending the service life of the gears and equipment and ensuring product quality.
[0058] The working principle of a gear hobbing machine for gear processing disclosed in this application is as follows: When processing a batch of gears, the gear to be processed is hoisted onto the housing 11, and the gear is lowered until the rotating wheel 43 on the sliding seat 32 can abut against the side of the gear. The descent is stopped. Multiple sliding seats 32 are driven by an electric telescopic rod to make the gear coaxial with the rotation axis of the support frame 31. The gear is placed on the bearing wheel 33 set on the support frame 31. A rotating block is installed on the support frame 31 according to the shaft hole diameter of the gear to be processed. The processing head 14 is driven by the processing component 12 to process the gear until the processing is completed. During cleaning, the control panel 13 controls the cooling component 2 to spray cleaning agent to rinse the gears, and at the same time controls the rotating block to rotate to rinse the gears evenly. While rotating, the burr brush 41 and scraper 44 clean the stubborn impurities on the gear surface, and at the same time the gear moves relative to the support frame 31. The support frame 31 is continuously rotated by the control console 13 to clean the gears and lift them out. If the gears need to be dried, an air inlet can be opened on the housing 11 and an external hot air blower can be connected to dry the gears inside the housing 11.
[0059] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
