Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a gear ring milling, chamfering, and deburring processing device. Background Technology

[0002] Gear rings are crucial components in mechanical transmissions, and their machining accuracy is critical to equipment performance. After milling, the tooth tip line and tooth profile of gear rings are typically sharp angles, and burrs easily appear on the edges. These burrs not only affect the gear meshing accuracy and reduce transmission efficiency but can also cause wear, noise, and even pose safety hazards such as scratches to operators. Furthermore, chamfering improves gear meshing quality, reduces the likelihood of worker injuries during transport, and effectively eliminates cracks that may occur during heat treatment, thus extending product lifespan. Therefore, chamfering and deburring after milling gear rings is an essential process.

[0003] While existing gear ring milling and chamfering devices can process gear rings, they still have some problems. Metal shavings generated during grinding can easily enter the inner wall of the worktable, making it inconvenient to clean them. At the same time, directly driving the gear ring to rotate via a motor may not allow for precise control of the rotation speed, thus affecting the grinding process of the gear ring. Utility Model Content

[0004] The main purpose of this invention is to provide a gear ring milling, chamfering, and deburring processing device, which aims to solve the technical problem that existing gear ring milling and chamfering devices, which directly drive the gear ring to rotate via a motor, may not be able to accurately control the rotation speed.

[0005] To achieve the above objectives, this utility model proposes a gear ring milling, chamfering, and deburring processing device, comprising a positioning mechanism and a processing mechanism. The positioning mechanism includes a placement disc, a protective shell, a clamping assembly, and a clamping drive assembly. The placement disc is rotatably mounted on the protective shell, the clamping assembly is slidably mounted on the placement disc, and the clamping drive assembly is installed inside the protective shell and the placement disc, and is drivenly connected to the clamping assembly. The processing mechanism includes a first fixed frame, a rotation drive assembly, a lifting drive assembly, a translation drive assembly, and a grinding assembly. The rotation drive assembly and the lifting drive assembly are mounted on the first fixed frame, the translation drive assembly is connected to the rotation drive assembly and the lifting drive assembly, and the grinding assembly is connected to the translation drive assembly.

[0006] The improved gear ring milling, chamfering, and deburring processing device of this utility model is further characterized in that the clamping assembly includes a connecting slider, an arc-shaped clamping plate, and a threaded screw. The top of the placement disc has a first sliding groove for the connecting slider to slide and install, and the bottom of the placement disc has a second sliding groove for the threaded screw to install. The first sliding groove and the second sliding groove correspond to and communicate with each other. The connecting slider is threadedly connected to the threaded screw. The arc-shaped clamping plate is fixed to the top of the connecting slider. The clamping drive assembly is drivenly connected to the threaded screw.

[0007] The improved gear ring milling, chamfering, and deburring processing device of this utility model is that the clamping drive assembly includes a rotating gear ring, a first gear, a second gear, and a manual crank. The rotating gear ring is rotatably mounted inside the protective circular shell and located on the outer periphery of the placement disc. The first gear is fixed to the end of the threaded screw and meshes with the rotating gear ring. The manual crank is rotatably mounted on the protective circular shell. The second gear is fixed to the end of the manual crank and meshes with the rotating gear ring.

[0008] The improved gear ring milling, chamfering, and deburring processing device of this utility model is that the sliding drive assembly includes a rotating sleeve, a sliding column, and an electric push rod. The rotating sleeve is rotatably mounted on the first fixed frame. The sliding column is slidably connected to the inside of the rotating sleeve via a spline. The electric push rod is rotatably connected to the top of the sliding column. The translation drive component is connected to the bottom of the sliding column. The first fixed frame is provided with a second fixed frame for mounting the electric push rod.

[0009] The improved gear ring milling, chamfering, and deburring processing device of this utility model is that the rotary drive assembly includes a first synchronous pulley, a second synchronous pulley, a synchronous belt, and a servo motor. The servo motor is driven and connected to the first synchronous pulley, the second synchronous pulley is fixed to the outer periphery of the rotating sleeve, the synchronous belt is driven and connected to the first synchronous pulley and the second synchronous pulley, and the first fixed frame is provided with a frame for fixing the servo motor.

[0010] The further improvement of the gear ring milling, chamfering, and deburring processing device of this utility model is that the translation drive component is an electric slide rail.

[0011] The further improvement of the gear ring milling, chamfering and deburring processing device of this utility model is that the grinding component includes a mounting frame, a grinding disc and a drive motor. The mounting frame is connected to the electric slide rail, the drive motor is installed in the mounting frame, and the drive motor drives the grinding disc.

[0012] The improved gear ring milling, chamfering, and deburring processing device of this utility model further includes a base plate, on which the first fixing frame is fixed and the placement circular plate is fixed on the base plate by a support frame.

[0013] The technical solution of this utility model has the following beneficial effects: This utility model relates to a gear ring milling, chamfering, and deburring processing device. Through the coordinated operation of a rotary drive component, a lifting drive component, and a translation drive component, the position of the grinding component is precisely adjusted. This solves the technical problem of existing gear ring milling and chamfering devices, which rely on a motor to directly drive the gear ring rotation, potentially leading to inaccurate speed control. This utility model utilizes a clamping component to achieve concentric clamping of gear rings of different diameters, ensuring high positioning accuracy and preventing gear ring misalignment during processing. A protective circular shell further protects the clamping drive component from metal debris generated during processing. The generated debris either remains on the surface of the placement plate or falls through the first sliding groove onto the lower base plate, facilitating easy cleaning.

[0014] This invention utilizes a servo motor to drive a second synchronous pulley via a first synchronous pulley and a synchronous belt, which in turn rotates a rotating sleeve. The rotating sleeve engages with a sliding column via a spline groove, causing the sliding column to rotate synchronously. Simultaneously, an electric push rod can push the sliding column to slide axially along the rotating sleeve, adjusting the height of the grinding mechanism. An electric slide rail at the bottom of the sliding column can adjust the horizontal position of the grinding mechanism, aligning it with the area to be processed on the gear ring. The servo motor controls the rotation speed via synchronous pulley transmission, ensuring a stable grinding trajectory and solving the problem of inaccurate speed control in traditional direct-drive motors. The electric push rod adjusts the height, and the electric slide rail adjusts the horizontal position; combined with the rotational movement of the sliding column, automated processing of multiple parts of the gear ring, such as flat surfaces, can be achieved, reducing manual intervention.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] like Figures 1-5 As shown, this utility model proposes a gear ring milling, chamfering, and deburring processing device, including a positioning mechanism 2 and a processing mechanism 3. The positioning mechanism 2 includes a placement disc 21, a protective shell 22, a clamping assembly, and a clamping drive assembly. The placement disc 21 is rotatably mounted on the protective shell 22. The clamping assembly is slidably mounted on the placement disc 21. The clamping drive assembly is installed inside the protective shell 22 and the placement disc 21, and is drivenly connected to the clamping assembly. The processing mechanism 3 includes a first fixed frame 31, a rotation drive assembly, a lifting drive assembly, a translation drive assembly, and a grinding assembly. The rotation drive assembly and the lifting drive assembly are mounted on the first fixed frame 31. The translation drive assembly is connected to the rotation drive assembly and the lifting drive assembly. The grinding assembly is connected to the translation drive assembly.

[0024] The number of clamping components can be set as needed, preferably three or more. In this embodiment, the number of clamping components is three. The synchronous clamping of the arc-shaped clamping plate 27 is achieved through a linkage of "rotating gear ring 23 + multiple sets of gears + threaded screw 210". Specifically, the rotating gear ring 23 meshes with multiple first gears 24, each first gear 24 being connected to a threaded screw 210. When the rotating gear ring 23 rotates, it drives all the threaded screws 210 to rotate synchronously, thereby causing the arc-shaped clamping plate 27 to move synchronously radially, achieving centering clamping of gear rings of different sizes. This mechanical synchronous clamping structure, which uses a single rotating gear ring 23 to link multiple sets of threaded screws 210, differs from traditional independent drive or asynchronous adjustment methods, ensuring the symmetry and stability of the positioning. The inner wall of the rotating sleeve 37 is provided with a spline groove, and the outer wall of the sliding column 38 is provided with a spline. The sliding cooperation between the two realizes the transmission of rotational torque (ensuring that the grinding mechanism 310 rotates synchronously with the rotating sleeve 37), and also allows the sliding column 38 to move axially (driven by the electric push rod 312), thereby adjusting the height of the grinding mechanism 310 to adapt to different processing requirements. The servo motor 33 drives the second synchronous pulley 36 (with a diameter larger than the first synchronous pulley 34) through the first synchronous pulley 34 and the synchronous belt 35 to achieve speed reduction transmission and precisely control the speed of the rotating sleeve 37, thereby ensuring the processing accuracy of the grinding mechanism 310. The combination of the spline structure and the synchronous pulley speed reduction transmission realizes the compound action of the grinding mechanism 310 of "rotational motion + axial lifting", and the speed is controllable.

[0025] Preferably, such as Figure 2 and Figure 3 As shown, the clamping assembly includes a connecting slider 211, an arc-shaped clamping plate 27, and a threaded screw 210. The top of the placement disc 21 has a first groove 28 for the connecting slider 211 to slide on, and the bottom of the placement disc 21 has a second groove 29 for the threaded screw 210 to be installed. The first groove 28 and the second groove 29 correspond to and communicate with each other. The connecting slider 211 is threadedly connected to the threaded screw 210. The arc-shaped clamping plate 27 is fixed to the top of the connecting slider 211. The clamping drive assembly is driven by the threaded screw 210. Specifically, the connecting slider 211 passes through the first groove 28 and the second groove 29, so that the rotation of the threaded screw 210 drives the connecting slider 211 to slide simultaneously within the first groove 28 and the second groove 29, thereby realizing the clamping and releasing of the gear ring by the clamping assembly.

[0026] Preferably, the clamping drive assembly includes a rotating gear ring 23, a first gear 24, a second gear 25, and a manual crank 26. The rotating gear ring 23 is rotatably mounted inside the protective circular shell 22 and located on the outer periphery of the placement disc 21. The first gear 24 is fixed to the end of the threaded screw 210 and meshes with the rotating gear ring 23. The manual crank 26 is rotatably mounted on the protective circular shell 22. The second gear 25 is fixed to the end of the manual crank 26 and meshes with the rotating gear ring 23. In this embodiment, the height of the placement disc 21 is higher than that of the rotating gear ring 23. The edge of the protective shell is provided with a baffle ring, so that an annular groove for mounting the rotating gear ring 23 is formed between the placement disc 21 and the protective circular shell 22. The protective shell is also provided with a cover plate covering the top of the rotating gear ring 23, thereby preventing metal debris from falling onto the rotating gear ring 23 and affecting the transmission function. The manual crank 26 can drive the second gear 25 to rotate, which in turn drives the rotating gear ring 23 to rotate, and simultaneously drives a set of first gears 24 to rotate, thereby driving the threaded screw 210 to rotate.

[0027] Preferably, such as Figure 4 and Figure 5As shown, the sliding drive assembly includes a rotating sleeve 37, a sliding column 38, and an electric push rod 312. The rotating sleeve 37 is rotatably mounted on the first fixed frame 31. The sliding column 38 is slidably connected to the inside of the rotating sleeve 37 via a spline. The electric push rod 312 is rotatably connected to the top of the sliding column 38, and the translation drive component is connected to the bottom of the sliding column 38. The first fixed frame 31 is provided with a second fixed frame 311 for mounting the electric push rod 312. Specifically, both the first fixed frame 31 and the second fixed frame 311 are inverted L-shaped. The inner wall of the rotating sleeve 37 is provided with a spline groove, and the outer wall of the sliding column 38 is fixedly mounted with a spline. The spline and spline groove allow the sliding column 38 to slide within the rotating sleeve 37, and when the rotating sleeve 37 rotates, it can drive the sliding column 38 to rotate together. Preferably, the rotary drive assembly includes a first synchronous pulley 34, a second synchronous pulley 36, a synchronous belt 35, and a servo motor 33. The servo motor 33 is driven and connected to the first synchronous pulley 34. The second synchronous pulley 36 is fixed to the outer periphery of the rotating sleeve 37. The synchronous belt 35 is drive-connected to the first synchronous pulley 34 and the second synchronous pulley 36. The first fixing frame 31 is provided with a frame 32 for fixing the servo motor 33. Further, the outer diameter of the second synchronous pulley 36 is larger than the outer diameter of the first synchronous pulley 34, thereby reducing the rotational speed of the second synchronous pulley 36.

[0028] Preferably, the translation drive is an electric slide rail 39. The electric slide rail 39 is existing technology and can drive the grinding mechanism 310 to move laterally, thereby driving the grinding mechanism 310 to process gear rings of different diameters. The grinding mechanism 310 is installed at the output end of the electric slide rail 39.

[0029] Preferably, the grinding assembly includes a mounting frame, a grinding disc, and a drive motor. The mounting frame is connected to the electric slide rail 39, and the drive motor is mounted inside the mounting frame and driven by the grinding disc. The grinding assembly is used to process gear rings. The grinding disc can be replaced with other devices for grinding gear rings. Through the cooperation of the processing mechanisms 3, the planes or steps of the gear ring can be chamfered and ground.

[0030] Preferably, it also includes a base plate 1, the first fixing frame 31 is fixed on the base plate 1, and the placement disc 21 is fixed on the base plate 1 by a support frame.

[0031] In use, the toothed ring is first placed on the placement circular plate 21. The manual crank 26 is then rotated, causing the second gear 25 to rotate, which in turn drives the rotating toothed ring 23 to rotate. The rotating toothed ring 23 meshes with a set of first gears 24, causing the threaded screw 210 connected to the first gear 24 to rotate synchronously within the second slide groove 29. As the threaded screw 210 rotates, the connecting slider 211, threaded to the outer wall, slides along the second slide groove 29, causing the arc-shaped clamping plate 27 to contract towards the center via the first slide groove 28, ultimately clamping and fixing the toothed ring. By synchronously driving multiple sets of arc-shaped clamping plates 27 through the rotation of the gear ring 23, concentric clamping of gear rings of different diameters is achieved, resulting in high positioning accuracy and preventing gear ring misalignment during processing. A protective circular shell 22 is also provided to protect the rotating gear ring 23, the first gear 24, and the second gear 25, preventing metal debris generated during processing from affecting them. The generated debris will only remain on the surface of the placement circular plate 21 or fall onto the lower base plate 1 through the first sliding groove 28, facilitating the cleaning of these metal debris. When the gear ring needs to be processed after being fixed, in the processing mechanism 3, the servo motor 33 drives the second synchronous wheel 36 to rotate through the first synchronous wheel 34 and the synchronous belt 35, thereby driving the rotating sleeve 37 to rotate. The rotating sleeve 37 engages with the sliding column 38 through a spline groove, causing the sliding column 38 to rotate synchronously. Simultaneously, the electric push rod 312 can push the sliding column 38 to slide axially along the rotating sleeve 37, adjusting the height of the grinding mechanism 310. The electric slide rail 39 at the bottom of the sliding column 38 can adjust the horizontal position of the grinding mechanism 310, aligning it with the part of the gear ring to be processed. The servo motor 33 controls the rotation speed through synchronous wheel transmission, ensuring a stable grinding trajectory and solving the problem of inaccurate speed in traditional direct-drive motors. The electric push rod 312 adjusts the height, and the electric slide rail 39 adjusts the horizontal position. Combined with the rotational movement of the sliding column 38, automated processing of multiple parts of the gear ring, such as flat surfaces, can be achieved, reducing manual intervention.

[0032] This utility model discloses a gear ring milling, chamfering, and deburring processing device. The gear ring is placed on a placement disc 21. Rotating the manual crank 26 drives the second gear 25 to rotate, which in turn drives the rotating gear ring 23, which meshes with it, to rotate. The rotating gear ring 23 meshes with a set of first gears 24, causing the threaded screw 210 connected to the first gears 24 to rotate synchronously within the second slide groove 29. When the threaded screw 210 rotates, the connecting slider 211, whose outer wall is threaded, slides along the second slide groove 29, causing the arc-shaped clamping plate 27 to contract towards the center through the first slide groove 28, ultimately clamping and fixing the gear ring. By rotating the gear ring 23, multiple sets of arc-shaped clamping plates 27 are driven synchronously to achieve concentric clamping of gear rings of different diameters, resulting in high positioning accuracy and preventing gear ring misalignment during processing. At the same time, a protective circular shell 22 is provided to protect the rotating gear ring 23, the first gear 24, and the second gear 25, preventing metal debris generated during processing from affecting them. Meanwhile, the debris generated during processing will only stay on the surface of the placement disc 21 or fall onto the lower base plate 1 through the first sliding groove 28, thus facilitating the cleaning of these metal debris.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
