Description

Technical Field

[0001] This utility model relates to the field of deburring technology, specifically a gear deburring device. Background Technology

[0002] As a key component in mechanical transmission systems, the machining quality of gears has a significant impact on the performance and reliability of mechanical equipment. During the gear manufacturing process, due to the inherent characteristics of machining processes such as cutting and stamping, burrs inevitably occur on the gear tooth surface, tooth tip, and tooth root.

[0003] The presence of burrs not only affects the appearance quality of gears, but also seriously harms their transmission accuracy, service life, and the operational stability of equipment. For example, in high-speed gear transmission systems, burrs can increase the impact and vibration during gear meshing, resulting in noise, accelerated wear, and even premature gear failure. Furthermore, burrs can affect the assembly accuracy of gears with other components, leading to assembly difficulties or decreased equipment performance after assembly.

[0004] Currently, the main methods for deburring gears include manual deburring, electrochemical deburring, abrasive flow deburring, and mechanical deburring. While manual deburring offers high flexibility, it is inefficient, labor-intensive, and struggles to guarantee consistent deburring quality. Electrochemical deburring may result in uneven deburring for gears with complex shapes and requires large amounts of electrolyte, leading to environmental pollution and high equipment maintenance costs. Abrasive flow deburring equipment is expensive, and process parameter control is complex, hindering large-scale production applications. Traditional mechanical deburring methods, such as using ordinary grinding wheels or cutting tools, struggle to handle different types and sizes of burrs, easily causing surface damage or incomplete deburring.

[0005] Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0025] 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.

[0026] Please see Figures 1-3 In this embodiment of the utility model, a gear deburring device includes a cabinet 1, on which a gear positioning mechanism and a deburring mechanism are integrated.

[0027] The gear positioning mechanism includes a first driving component 2 and a gear positioning connector 3 connected to the power end of the first driving component 2. The deburring mechanism includes a second driving component 4 and a deburring roller 5 connected to the power end of the second driving component 4. The deburring roller 5 corresponds to the gear positioning connector 3.

[0028] The deburring roller 5 includes a hard part 6 located in the middle and flexible grinding wheel parts 7 respectively disposed on both sides of the hard part 6, and the height of the hard part 6 is lower than that of the flexible grinding wheel parts 7 on both sides.

[0029] In this utility model technical solution, the first driving component 2 of the gear positioning mechanism provides power to the gear positioning connector 3, enabling it to accurately fix the gear according to the shape and size of the gear. The accurate positioning avoids the displacement of the gear during the deburring process and ensures that the deburring roller 5 can accurately act on the burr area.

[0030] The central hard part 6 of the deburring roller 5 is made of materials such as ceramic, metal or cemented carbide, which has high hardness and strong cutting force. It is used to remove tall and hard burrs. The flexible grinding wheel parts 7 on both sides are made of rubber-abrasive composite material or resin-abrasive composite material or other materials. They have good flexibility and elasticity and can closely fit the gear end face to grind low burrs. The height of the hard part 6 is lower than that of the flexible grinding wheel parts 7 on both sides. This design allows the deburring roller 5 to first contact the gear end face with the higher flexible grinding wheel parts 7 to perform preliminary grinding and cleaning of the gear surface when it is working. This reduces the impact of the hard part 6 on the gear surface when it contacts the gear. At the same time, it also ensures that the flexible grinding wheel parts 7 can give full play to their fitting characteristics to deal with low burrs. When encountering tall burrs, the central hard part 6 will play a role to perform targeted removal.

[0031] The gear positioning mechanism and the deburring mechanism work together. The gear positioning connector 3 and the deburring roller 5 are positioned correspondingly. After the gear positioning mechanism fixes the gear, the second drive component 4 of the deburring mechanism drives the deburring roller 5 to rotate, thereby achieving the deburring action on the gear.

[0032] In summary, automated operation reduces manual intervention, shortens the deburring time for a single gear, and increases the processing quantity per unit time. The deburring rollers 5 have clearly defined functions, reducing tool change and parameter adjustment time. The height difference design between the hard part 6 and the flexible grinding wheel part 7 allows the rollers to switch naturally when processing different burrs, improving deburring efficiency and meeting the needs of large-scale production.

[0033] In this embodiment of the present invention, the front end of the hard part 6 forms a blade structure 8.

[0034] The front end of the hard part 6 of the deburring roller 5 is designed as a blade structure 8. Based on the principles of mechanics and material removal, the blade is made of materials with extremely high hardness, such as cemented carbide or ceramic. When it comes into contact with high and hard burrs, the blade can generate great pressure under the same force by utilizing the characteristic of the extremely small contact area. According to the principle of shearing force, the concentrated force can efficiently shear the burrs, realize the rapid and precise separation of burrs from the gear surface, and complete the removal operation.

[0035] Furthermore, when removing burrs, the blade, with its sharp and precise cutting ability, produces a clean cut, greatly reducing damage to the gear parts around the burrs. This avoids affecting the gear tooth shape and surface accuracy due to improper burr removal, ensuring the subsequent transmission accuracy of the gear and extending its service life.

[0036] In this embodiment of the present invention, the second driving component 4 includes a Y-axis linear module 9 and a first motor assembly 10 connected to the movable end of the Y-axis linear module 9. The power end of the first motor assembly 10 is connected to the deburring roller 5 through a first connector 11. The Y-axis linear module 9 is used to drive the first motor assembly 10 to perform vertical linear motion to adjust the relative position of the deburring roller 5 with respect to the gear positioning connector 3.

[0037] The second drive component 4 adopts a design combining a Y-axis linear module 9 and a first motor assembly 10. The Y-axis linear module 9 utilizes mechanical structures such as linear guides and ball screws to drive the screw to rotate via a motor, converting rotational motion into linear motion. This drives the first motor assembly 10, which is installed at its movable end, to move precisely in the vertical direction. The first motor assembly 10 provides rotational power to the deburring roller 5, enabling it to perform grinding operations. By adjusting the relative position of the deburring roller 5 and the gear positioning connector 3 through the Y-axis linear module 9, it is ensured that the deburring roller 5 can accurately contact the burr part of the gear in different working scenarios, thus realizing the deburring operation of gears of different sizes and shapes.

[0038] Furthermore, the first connecting piece 11 serves to connect the first motor assembly 10 and the deburring roller 5. Its design must ensure the stability and concentricity of the connection between the two. It is usually made of high-strength metal materials, such as aluminum alloy or steel, with sufficient strength and rigidity to withstand the torque and vibration during the deburring process. If the first motor assembly 10 and the deburring roller 5 are directly connected, the structure of the first connecting piece 11 is relatively simple, mainly to achieve mechanical fixation between the two and ensure that power can be directly transmitted. If connected through a transmission component, such as a combination of a synchronous pulley and a synchronous belt, one end of the first connecting piece 11 is connected to the output shaft of the first motor assembly 10, and the other end is connected to the synchronous pulley. The synchronous belt connects the two synchronous pulleys, transmitting the power of the motor to the deburring roller 5. By using the synchronous pulley and synchronous belt transmission, a precise transmission ratio can be achieved, ensuring the stable speed of the deburring roller 5, and can also buffer the impact when the motor starts and stops to a certain extent.

[0039] In this embodiment of the present invention, the second driving component 4 further includes an X-axis linear module 12, and the Y-axis linear module 9 is connected to the movable end of the X-axis linear module 12. The X-axis linear module 12 is used to drive the first motor assembly 10 to perform horizontal linear motion in order to adjust the relative position of the deburring roller 5 to the gear positioning connector 3.

[0040] The design principle of the X-axis linear module 12 is similar to that of the Y-axis linear module 9. It also uses mechanical structures such as linear guides and ball screws. The motor drives the ball screw to rotate, converting the rotational motion into linear motion, which in turn drives the Y-axis linear module 9 and the first motor assembly 10 connected to its movable end to move precisely in the horizontal direction. Through this design, the relative position of the deburring roller 5 and the gear positioning connector 3 in the horizontal direction can be flexibly adjusted. Together with the Y-axis linear module 9, the deburring roller 5 can move precisely in the two-dimensional plane, meeting the burr removal requirements of different gears at different positions, and further improving the adaptability of the equipment to deburring operations of various complex gears.

[0041] In this embodiment of the present invention, the first driving component 2 includes a fixed box 13 and a second motor assembly (not shown) installed in the fixed box 13. The power end of the second motor assembly is connected to the gear positioning connector 3 through a second connector 14, and the gear positioning connector 3 is located on the surface of the fixed box 13.

[0042] The fixed box 13 provides a stable support structure for the entire first drive component 2, securely installs the second motor assembly inside, protects the motor assembly from external factors such as dust and debris, and ensures stable operation of the motor. At the same time, the fixed box 13 provides an installation reference for the second connector 14 and the gear positioning connector 3, ensuring the relative positional accuracy between the components.

[0043] The second motor assembly serves as a power source, outputting stable rotational power. This rotational power is transmitted to the gear positioning connector 3 through the second connector 14, driving the gear placed on it to rotate, so that each part of the gear can be in the working range of the deburring roller 5 in sequence, meeting the needs of all-round deburring.

[0044] One end of the second connector 14 is connected to the power end of the second motor assembly, and the other end is connected to the gear positioning connector 3. The connection is rigid, such as a key connection or a coupling connection. This connection method ensures that there will be no slippage or loosening during the torque transmission process, and ensures that the rotational power of the motor can be stably and accurately transmitted to the gear positioning connector 3, thereby driving the gear to rotate smoothly. Alternatively, the second connector 14 can also be connected to the first connector 11 through a corresponding transmission component, as described above, which will not be repeated here.

[0045] In this embodiment of the present invention, the gear positioning connector 3 includes a positioning member 15 and a locking member 16 detachably connected to the positioning member 15, wherein the positioning member 15 has a positioning structure 17 for placing the gear.

[0046] The positioning component 15 is provided with a positioning structure 17 specifically for placing the gear. It is designed according to the shape characteristics of the gear. For example, for common cylindrical gears, the positioning structure 17 may be a cylindrical shaft that matches the inner hole of the gear. Through interference fit or clearance fit, it ensures that the gear can be accurately fitted onto the positioning component 15, thereby achieving the initial positioning of the gear in the plane position and providing a reference for subsequent locking and machining operations.

[0047] The locking element 16 and the positioning element 15 are detachably connected by means such as bolts, nuts or clips. When the gear is placed on the positioning structure 17 of the positioning element 15, the locking element 16 is installed to apply a certain pressure to the gear, so that it is tightly fixed on the positioning element 15. Taking the bolt connection as an example, when the bolt is tightened, the axial force of the bolt increases the friction between the gear and the positioning element 15, preventing the gear from shifting or loosening during rotation, and ensuring the stability of the gear during the deburring process.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
