Description

Technical Field

[0001] This invention relates to the field of gear shaving technology, specifically to an automatic dust-free shaving device for the production of worm gears for geared motors. Background Technology

[0002] The worm gear is the core component of the geared motor's reduction transmission. Its tooth surface accuracy and cleanliness directly affect the motor's transmission efficiency, operational stability, and service life. Shaving is a crucial process in the finishing of worm gears, and its quality directly determines the final product performance. Currently, existing worm gear shaving processes generally suffer from the following technical defects, making it difficult to meet the high-quality, high-efficiency, and dust-free requirements of industrial mass production:

[0003] First, the shaving process generates a large amount of metal shavings. At the same time, in order to reduce the processing temperature and reduce tooth surface wear, cutting fluid needs to be continuously sprayed into the processing area. Most existing devices do not have an effective liquid-shaving separation mechanism, which causes metal shavings and cutting fluid to mix and accumulate in the processing area and inside the device. This not only pollutes the processing environment and causes dust to overflow, but also makes it impossible to recycle and reuse the cutting fluid, resulting in material waste and increased processing costs.

[0004] Secondly, the tooth backlash structure of worm gears is special, and metal debris generated during processing is prone to remain deep in the tooth backlash. Existing devices lack a targeted tooth backlash removal mechanism and can only remove impurities through manual cleaning or machine shutdown and blowing. This not only results in low cleaning efficiency and increased labor intensity, but also leads to processing interruption, seriously affecting production continuity. Furthermore, manual cleaning is difficult to completely remove residual impurities in the tooth backlash, which can easily cause problems such as tooth surface wear and decreased meshing accuracy, thus affecting the processing quality of worm gears.

[0005] In addition, although some existing shaving devices attempt to set up simple filtration or collection structures, most of them require additional drive components, resulting in complex structures, poor operational reliability, and the inability to simultaneously perform shaving, liquid-chip separation, and tooth gap cleaning. They still require frequent shutdowns to clean the filter screen and impurities, making them unsuitable for the needs of industrial mass production. Furthermore, their dust-free effect is poor, and metal chips and cutting fluid splash during processing can easily affect operators and the surrounding environment.

[0006] In view of the shortcomings of the existing technology, there is an urgent need to develop an automatic dust-free gear shaving device for the production of worm gears for geared motors that can simultaneously perform gear shaving, impurity removal, and liquid-chip separation, has a simple structure, reliable operation, and can effectively improve processing efficiency, processing quality, and dust-free level. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic dust-free shaving device for producing worm gears for geared motors, to solve the problems mentioned in the background art, such as the mixing of cutting fluid and metal shavings, difficulty in removing residual impurities in the tooth gaps, dust overflow in the processing environment, and the need for machine shutdown for cleaning. To achieve the above objective, this invention provides the following technical solution: an automatic dust-free shaving device for producing worm gears for geared motors, including a machine base, a shaving cutter, a bracket, and a baffle. The shaving cutter is arranged on the upper side of the machine base. The bracket is fixedly arranged on the machine base surface, and a circular shell is fixedly arranged on both sides of the bracket. A disc is rotatably arranged inside the circular shell. Both the disc and the circular shell have notches for inserting the gear shaft of the worm gear to be processed. A shaft support is arranged in the notch, and the shaft support is fixedly connected to the disc. Two elastic buckles are fixedly arranged on the shaft support. The gear shafts on both sides of the worm gear to be processed are correspondingly engaged into the elastic buckles of the two shaft supports, realizing the positioning and fixing of the worm gear to be processed.

[0008] Two baffles are provided, which are fixedly installed on the machine table and located between two round shells. The bottom of each round shell has an oil leakage port.

[0009] Preferably, the baffles are arranged in parallel relative to each other, forming a receiving area between them, and the outer sides of the two baffles are respectively set to correspond one-to-one with the oil leakage ports at the bottom of the two round shells.

[0010] Preferably, a semi-annular guide support is fixedly provided in the middle of the bracket. The guide support is located on the lower side of the worm gear to be processed. The guide support is provided with inclined openings on both sides of the two discs. The side of the disc opposite to the inclined opening is provided with an open structure. Several wall grooves are uniformly arranged in a ring on the side of the disc opposite to the inclined opening. The groove body of the wall groove is located inside the disc and extends radially along the disc. The groove opening is located on the side wall of the disc.

[0011] Preferably, the groove is provided with a drain hole that penetrates the inner wall of the disc. The rotating disc can use centrifugal force to throw the cutting fluid mixed in the groove into the shell through the drain hole. The cutting fluid in the shell flows out through the oil drain at the bottom of the shell.

[0012] Preferably, the groove is provided with a flexible filter screen with a recessed structure, and a sliding hole is opened in the groove to pass through the outer ring of the disc. A movable pin is slidably arranged in the sliding hole. The inner end of the movable pin is fixedly connected to the flexible filter screen. A protrusion is fixedly arranged at the inner bottom of the disc. When the movable pin rotates with the disc, it can periodically contact the protrusion and be pushed into the groove by the protrusion.

[0013] Preferably, when the movable pin is pushed into the wall groove by the protrusion, it can drive the flexible filter screen to move towards the groove opening, so that the flexible filter screen forms an inclined structure facing the groove opening. The metal debris on the flexible filter screen can be thrown out by the rotation of the disc and pass through the tooth gap of the worm gear to be processed.

[0014] Preferably, the shaving cutter meshes with the worm gear to be processed. When the shaving cutter rotates, it drives the worm gear to be processed to rotate synchronously. The worm gear to be processed is fixedly connected to the shaft support on both sides through the gear shafts on both sides, which drives the discs on both sides to rotate synchronously in the corresponding circular shells.

[0015] Preferably, the receiving area is used to receive metal chips that have passed through and been ejected from the tooth gap of the worm gear to be processed, and the area on the outside of the baffle corresponding to the oil drain is used to collect the cutting fluid flowing out from the oil drain.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention achieves simultaneous integration of gear shaving, separation of cutting fluid and metal chips, automatic backlash removal, and centralized collection of fluid and chips. It effectively solves the technical problems of dust overflow, fluid-chip accumulation, difficulty in removing residual impurities from backlash, and the need for frequent machine shutdowns for cleaning in existing gear shaving devices. This significantly improves the processing continuity of the worm gear of the geared motor, optimizes the cleanliness of the processing environment, greatly increases processing efficiency, and reduces manual cleaning costs. Through the coordinated operation of various components, multiple processes can be carried out simultaneously without the need for additional complex separation equipment and impurity removal mechanisms. This simplifies the processing flow, avoids time-consuming connections between processes, and further improves production efficiency. Simultaneously, the dust-free design effectively reduces environmental pollution from dust and cutting fluid during processing, meeting the requirements of green production, and also avoids the impact of dust and impurities on processing accuracy, ensuring the processing quality of the worm gear.

[0018] In this invention, the rotational power of the shaving process itself simultaneously achieves centrifugal liquid-chip separation, flexible filter self-cleaning, and impurity removal from the tooth gaps. This eliminates the need for additional drive components and separation equipment, simplifying the device structure, improving operational reliability, and effectively reducing manufacturing costs and long-term energy consumption. It is well-suited to the actual needs of industrial mass production, demonstrating strong practicality and economy. The direct and stable power transmission method ensures the synchronization of all components, reducing the probability of equipment failure and lowering maintenance costs. Furthermore, all components are made of wear-resistant and corrosion-resistant materials, extending the device's service life and further reducing long-term operating costs. It is adaptable to the machining requirements of different specifications of worm gears, expanding the device's applicability and enhancing its versatility and practicality.

[0019] In this invention, the design of metal debris re-passing through the tooth gap forms an in-situ secondary grinding of the tooth gap, which can accurately remove burrs and residual impurities deep in the tooth gap, significantly improving the machining accuracy and surface quality of the worm gear.

[0020] Meanwhile, the corresponding baffles and oil drain ports enable the separate collection of cutting fluid and metal shavings, facilitating the recycling and reuse of cutting fluid, reducing material waste, and further lowering processing costs. This demonstrates significant technical advantages and application value. In-situ secondary grinding of the tooth backlash eliminates the need for additional grinding processes and equipment, achieving deep cleaning and grinding of the tooth backlash, improving the smoothness and meshing accuracy of the worm gear, ensuring the operational stability of the geared motor, and effectively conserving resources and reducing material waste through cutting fluid recycling. This aligns with the concept of energy conservation and environmental protection in production. The centralized collection of metal shavings also facilitates subsequent recycling and processing, improving resource utilization and further reducing processing costs, resulting in significant economic and social benefits.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 8 The present invention provides a technical solution: an automatic dust-free shaving device for producing worm gears for geared motors, comprising a machine base 1, a shaving cutter 2, a bracket 3, and a baffle 9. The shaving cutter 2 is provided on the upper side of the machine base 1 and is used to shave the worm gears to be processed.

[0032] The bracket 3 is fixed on the table surface of the machine base 1 and serves as the support structure for the entire device. Circular shells 4 are fixedly installed on both sides of the bracket 3. The circular shells 4 provide installation space for the rotation of the disc 5. The disc 5 is rotatably installed inside the circular shells 4 and can rotate freely inside the circular shells 4.

[0033] Two baffles 9 are provided, fixed to the table surface of the machine base 1 and located between the two circular shells 4. Each circular shell 4 has an oil drain port 11 at its bottom to drain the cutting fluid collected inside. To ensure the stability of the entire device, the machine base 1 adopts a rigid structure design, effectively bearing the weight of each component and preventing vibrations during gear shaving from affecting machining accuracy. Simultaneously, the table surface of the machine base 1 is treated with anti-slip material to further enhance the installation firmness of each fixed component, preventing loosening and machining deviations. The shaving cutter 2 adopts a structure design adapted to the tooth profile of worm gears, precisely fitting the tooth surface of the worm gear to be machined, ensuring the accuracy of the gear shaving process. Furthermore, the installation height of the shaving cutter 2 can be finely adjusted according to the specifications of the worm gear to be machined, adapting to the machining needs of worm gears of different sizes and expanding the applicability of the device.

[0034] Both the disc 5 and the shell 4 have notches 6 for inserting the gear shaft of the worm gear to be processed. The size of the notch 6 is adapted to the gear shaft of the worm gear to be processed, facilitating the insertion and removal of the gear shaft. A shaft support 7 is fixedly installed inside the notch 6, and the shaft support 7 is fixedly connected to the disc 5. Two elastic clips 8 are fixedly installed on the shaft support 7, and the two elastic clips 8 are symmetrically arranged. The gear shafts on both sides of the worm gear to be processed are correspondingly inserted into the elastic clips 8 of the two shaft supports 7. The elastic clamping force of the elastic clips 8 achieves the positioning and fixation of the worm gear to be processed, ensuring that the gear will not shift during the shaving process. The elastic clips 8 are made of wear-resistant and highly elastic material, which can ensure the clamping force on the gear shaft while avoiding damage to the gear shaft during the clamping process. At the same time, the opening size of the elastic clip 8 can be adaptively adjusted according to the diameter of the gear shaft to adapt to different specifications of gear shafts without the need for additional replacement of clip parts, improving the convenience of operation. The disc 5 and the shell 4 are designed with a clearance fit, which ensures that the disc 5 can rotate flexibly and prevents the cutting fluid and metal chips from overflowing from the gap due to excessive clearance, thus ensuring the dust-free effect of the device. At the same time, the inner wall of the shell 4 is smoothed to reduce the friction when the disc 5 rotates, reduce the wear during the operation of the device, and extend the service life of the device.

[0035] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, two baffles 9 are arranged in parallel relative to each other, forming a receiving area 10 between them. This receiving area 10 is used to receive metal chips that have passed through and been ejected from the tooth gap of the worm gear to be processed, thereby achieving centralized collection of metal chips.

[0036] The outer sides of the two baffles 9 are respectively positioned to correspond one-to-one with the oil drain ports 11 at the bottom of the two circular shells 4, allowing the cutting fluid flowing from the oil drain ports 11 to fall into the corresponding areas on the outer sides of the baffles 9, achieving separate collection of cutting fluid and metal chips, and preventing them from mixing and accumulating. The baffles 9 are made of transparent and wear-resistant material, which not only allows operators to observe the internal processing status and the collection status of chips and cutting fluid, but also prevents metal chips and cutting fluid from splashing outside the device during processing, causing pollution to the processing environment. At the same time, the height of the baffles 9 is higher than the height of the worm gear to be processed, ensuring that it can completely block the splashing of chips and cutting fluid, further improving the dust-free effect. The bottom of the receiving area 10 is designed with an inclination, which facilitates the collection of metal chips in the center of the area, making subsequent centralized cleaning convenient and eliminating the need for operators to clean point by point, thus improving cleaning efficiency.

[0037] A collection container can be placed in the area on the outside of the baffle 9 corresponding to the oil drain 11, which facilitates the centralized collection and recycling of cutting fluid, reduces material waste, and lowers processing costs.

[0038] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a semi-annular guide support 12 is fixedly installed in the middle of the bracket 3. The guide support 12 is located on the lower side of the worm gear to be processed and is used to receive the cutting fluid and metal chips sprayed on the top processing area of ​​the gear. The guide support 12 has inclined openings 13 on both sides opposite to the two discs 5. The inclined openings 13 facilitate the smooth flow of cutting fluid and metal chips into the wall grooves 14 of the discs 5. The side of the shell 4 opposite to the inclined openings 13 is set as an open structure to ensure that the cutting fluid and chips on the guide support 12 can smoothly enter the wall grooves 14. The inner wall of the guide support 12 is smoothed to reduce the adhesion of cutting fluid and metal chips on the guide support 12, ensuring that the cutting fluid and chips can slide off smoothly and avoid accumulating in the guide support 12 and affecting the operation of the device. At the same time, the curvature of the guide support 12 is adapted to the curvature of the worm gear to be processed, which can fully receive the dripping cutting fluid and splashing metal chips during the processing and avoid leakage. The tilt angle of the inclined port 13 is reasonably designed to ensure that the cutting fluid and debris can flow smoothly into the wall groove 14, while avoiding excessive flow rate that could cause the cutting fluid to splash. The opening structure of the round shell 4 is precisely connected to the inclined port 13 to ensure that no cutting fluid or debris overflows from the connection point, further improving the stability of the liquid and debris collection.

[0039] A number of wall grooves 14 are uniformly arranged in a ring on one side of the disc 5 relative to the inclined opening 13. The opening of the wall grooves 14 is located on the side wall of the disc 5, and the wall grooves 14 extend radially along the disc 5 to provide a smoother flow channel for cutting fluid and metal chips, and to prevent the accumulation of fluid and chips at the connection between the wall grooves 14 and the disc 5.

[0040] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8As shown, a drain hole 15 is provided in the wall groove 14, penetrating the inner wall of the disc 5. The rotating disc 5 uses centrifugal force to throw the cutting fluid mixed in the wall groove 14 into the shell 4 through the drain hole 15. The cutting fluid in the shell 4 flows out through the oil drain 11 at the bottom and falls into the corresponding area outside the baffle 9 for collection, achieving preliminary separation of cutting fluid and metal chips. The number and size of the wall grooves 14 are reasonably designed to match the rotation speed of the disc 5, ensuring that cutting fluid and metal chips can enter the wall grooves 14 in a timely manner, avoiding accumulation on the surface of the disc 5. At the same time, the walls of the wall grooves 14 are smoothed to reduce the adhesion of cutting fluid and chips, facilitating subsequent cleaning. The diameter of the drain hole 15 is precisely controlled to ensure that the cutting fluid can pass smoothly while preventing metal chips from entering the shell 4 through the drain hole 15, ensuring the effect of liquid-chip separation. At the same time, multiple drain holes 15 are evenly distributed in the wall grooves 14 to improve the discharge efficiency of cutting fluid and prevent cutting fluid from accumulating in the wall grooves 14.

[0041] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a flexible filter screen 16 with a recessed structure is provided in the wall groove 14. The flexible filter screen 16 is used to trap metal debris in the wall groove 14, preventing the debris from being thrown into the cylindrical shell 4 along with the cutting fluid. A sliding hole 17 penetrating the outer ring of the disc 5 is opened in the wall groove 14. A movable pin 18 is slidably disposed in the sliding hole 17. The movable pin 18 can slide freely along the sliding hole 17. The inner end of the movable pin 18 is fixedly connected to the flexible filter screen 16. A protrusion 19 is fixedly disposed on the inner bottom of the cylindrical shell 4. When the movable pin 18 rotates with the disc 5, it can periodically contact the protrusion 19 and be pushed into the wall groove 14 by the protrusion 19. The recessed structure of the flexible filter screen 16 can increase the contact area with metal debris, improve the debris trapping effect, and at the same time, the flexible filter screen 16 is made of a corrosion-resistant and wear-resistant flexible material, which can adapt to the rotation of the disc 5 and the pushing of the movable pin 18, avoid filter screen damage, and extend the service life of the filter screen. The inner wall of the sliding hole 17 is lubricated to reduce friction when the moving pin 18 slides, ensuring that the moving pin 18 can slide flexibly. At the same time, the size of the sliding hole 17 is adapted to the moving pin 18 to avoid jamming during the sliding process, ensuring the stable operation of the filter's self-cleaning function. The height and position of the protrusion 19 are reasonably designed to ensure that the moving pin 18 is accurately pushed in when it rotates to the corresponding position, realizing the periodic deformation of the flexible filter 16. At the same time, the protrusion 19 is made of wear-resistant material to reduce wear when in contact with the moving pin 18, ensuring the long-term stable operation of the device.

[0042] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8As shown, when the movable pin 18 is pushed into the wall groove 14 by the protrusion 19, it can drive the flexible filter screen 16 to move towards the opening of the wall groove 14, so that the flexible filter screen 16 forms an inclined structure facing the opening. The metal debris on the flexible filter screen 16 can be thrown into the guide support 12 by the rotation of the disc 5 and pass through the tooth gap of the worm gear to be processed. During the process of passing through the tooth gap, the debris can polish and remove the burrs and residual impurities in the tooth gap, realizing automatic impurity removal from the tooth gap. The tilt angle of the flexible filter screen 16 can be adjusted by the pushing depth of the movable pin 18 to ensure that the metal debris can be smoothly thrown under the action of centrifugal force. At the same time, the inclined structure can prevent the debris from accumulating on the filter screen and improve the self-cleaning effect of the filter screen. The force of metal shavings ejection can be controlled by the rotation speed of disc 5, which is synchronized with the rotation speed of the worm gear to be processed. No additional adjustment is required, which not only ensures the effect of removing impurities from the tooth gap, but also simplifies the operation process of the device. When the metal shavings pass through the tooth gap, they can accurately act on the burrs and residual impurities deep in the tooth gap, realize in-situ secondary grinding, and further improve the processing accuracy and surface quality of the worm gear.

[0043] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, the shaving cutter 2 meshes with the worm gear to be processed. When the shaving cutter 2 rotates, it drives the worm gear to be processed to rotate synchronously. Since the gear shafts on both sides of the worm gear to be processed are fixedly connected to the shaft support 7, and the shaft support 7 is fixedly connected to the disc 5, the rotation of the worm gear to be processed will synchronously drive the discs 5 on both sides to rotate synchronously in the corresponding circular shells 4. The entire device does not require additional drive components. It can achieve liquid-chip separation, filter self-cleaning, and tooth gap removal by utilizing the rotational power of the shaving process itself. The structure is simple and the operation is reliable. This power transmission method does not require an additional power source, which not only reduces the manufacturing cost of the device but also reduces energy consumption, meeting the requirements of energy conservation and environmental protection. At the same time, the power transmission is direct and stable, which can ensure the synchronous operation of each component and avoid processing deviations or device failures caused by power transmission lag. In addition, the connections between each component are all firmly fixed to ensure that there is no loosening during the power transmission process, further improving the operational reliability of the device, adapting to the needs of long-term continuous operation in industrial mass production, reducing the frequency of equipment downtime maintenance, and improving production efficiency.

[0044] The method of using an automatic impurity removal and dust-free gear shaving device for producing worm gears for geared motors includes the following steps:

[0045] S1. The gear shafts on both sides of the worm gear to be processed are inserted into the elastic buckles 8 of the two shaft supports 7 through the notches 6 on the disc 5 and the shell 4. The elastic clamping force of the elastic buckles 8 completes the positioning and fixing of the worm gear to be processed, ensuring that the gear and the shaving cutter 2 mesh with each other.

[0046] S2. Start the shaving cutter 2. The shaving cutter 2 rotates and drives the worm gear to be processed to rotate synchronously, and the shaving process begins.

[0047] When the worm gear to be processed rotates, it synchronously drives the discs 5 on both sides to rotate synchronously in the corresponding circular shells 4.

[0048] S3. Spray cutting fluid onto the machining area of ​​the worm gear to be machined. The cutting fluid, together with the metal chips generated by shaving, falls onto the semi-annular guide support 12, and then flows into the wall groove 14 on the disk 5 along the inclined openings 13 on both sides of the guide support 12.

[0049] S4, the disc 5 rotates synchronously with the worm gear to be processed, generating centrifugal force. Under the action of centrifugal force, the cutting fluid in the wall groove 14 is thrown into the shell 4 through the leakage hole 15 in the wall groove 14. The cutting fluid in the shell 4 gradually gathers to the bottom and flows out through the oil leakage port 11 at the bottom of the shell 4, falling into the corresponding area outside the baffle 9 for collection.

[0050] Metal debris in the wall groove 14 is trapped by the flexible filter screen 16, thus separating the cutting fluid from the metal debris.

[0051] S5. During the rotation of the disc 5, the movable pin 18 in the wall groove 14 periodically contacts the protrusion 19 at the bottom of the shell 4 and is pushed into the wall groove 14 by the protrusion 19. The movable pin 18 drives the flexible filter screen 16 to move towards the groove opening of the wall groove 14, so that the flexible filter screen 16 forms an inclined structure facing the groove opening.

[0052] Metal debris on the flexible filter screen 16 is thrown into the guide bracket 12 by centrifugal force, and then passes through the tooth gap of the worm gear to be processed, polishing and removing burrs and residual impurities in the tooth gap.

[0053] S6. The metal debris that passes through the tooth gap is thrown into the receiving area 10 between the two baffles 9, so as to achieve centralized collection of the metal debris.

[0054] The cutting fluid continuously flows out from the oil drain 11 and is collected separately. The entire machining process does not require machine shutdown for cleaning, achieving dust-free continuous machining.
