Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a gear hobbing and shaving follow-up processing device. Background Technology

[0002] With the rapid development of technology, gears, as core transmission components, have been widely integrated into everyday scenarios such as automotive transmissions, smart home motors, and power tools. The market demand for their processing efficiency and precision is constantly increasing. In traditional gear processing, hobbing and shaving are two key processes. Hobbing, as a roughing process, uses a hob to generate the basic tooth shape of the gear. Shaving, as a finishing process, uses a shaving cutter to correct errors, reduce tooth surface roughness, and ensure transmission smoothness. However, early processing adopted a separate equipment and step-by-step operation mode. The gear had to be roughed on the hobbing machine first, and then manually transferred to the shaving machine for re-clamping, positioning, and tool setting adjustment. This process not only consumed a lot of manpower and time, but the secondary clamping was also prone to causing reference deviation, resulting in a decrease in precision and making it difficult to meet the needs of mass production. Therefore, a gear hobbing and shaving accompanying processing device was developed.

[0003] After the device is started, the accompanying fixture has a positioning mandrel that matches the inner hole of the gear. After the gear blank is fitted into the mandrel, the clamping assembly automatically moves to firmly fix the workpiece from the radial or axial direction, ensuring that the workpiece is always positioned with the same reference in subsequent processing and avoiding secondary clamping errors. After positioning is completed, the accompanying mechanism drives the fixture and the workpiece to move precisely to the gear hobbing machining station. At this time, the hob spindle of the gear hobbing module starts and the hob rotates at high speed at a preset speed. At the same time, the workpiece spindle drives the gear blank to rotate synchronously, and the two form a generating motion. During this period, the feed adjustment mechanism controls the hob to slowly cut in along the workpiece axis and gradually mill out the tooth shape that meets the design parameters to complete the machining.

[0004] Currently, gear hobbing and shaving follow-up processing devices have significantly improved the accuracy and efficiency of gear processing due to their core advantages of single clamping and continuous processing. They have effectively solved some of the pain points in equipment processing and provided key support for the large-scale and precision production of the gear manufacturing industry, playing a significant positive role in promoting the industry's development. However, the device currently has obvious limitations. Its clamping structure is mostly designed with fixed specifications and can only be adapted to gear blanks of specific sizes and bore diameters. When dealing with gear materials with different modules, different inner diameters, or different thicknesses, it is necessary to frequently change the clamping components and readjust the positioning reference. This not only increases operating costs and time but also affects processing accuracy due to replacement errors, making it difficult to meet the needs of multi-specification small-batch production. Therefore, a gear hobbing and shaving follow-up processing device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a gear hobbing and shaving follow-up processing device, which aims to improve the problem that the existing technology cannot clamp materials of different specifications.

[0006] To achieve the above objectives, this utility model provides a gear hobbing and shaving follow-up processing device, including a base, a housing fixedly connected to the top of the base, a weighing block slidably connected to the inner wall of the housing, a motor fixedly connected to the inner wall of the base, a hobbing cutter fixedly connected to the drive end of the motor, a transmission mechanism fixedly connected to the other side of the hobbing cutter, a threaded column rotatably connected to the inner wall of the housing, a slider slidably connected to the inner wall of the housing, and a fixing mechanism slidably connected to the outer wall of the weighing block.

[0007] The fixing mechanism includes a fixing block, a cylinder is fixedly connected to the inner wall of the fixing block, a fixing plate is fixedly connected to the driving end of the cylinder, a gasket is fixedly connected to one side of the fixing plate, a fixing column is fixedly connected to the bottom of the slider, and material is slidably connected to the outer wall of the fixing column. The transmission mechanism includes a driven wheel two, and a differential assembly is fixedly connected to one side of the driven wheel two.

[0008] The differential assembly includes a first gear, one side of which is fixedly connected to one side of the driven wheel 2; a second gear is rotatably connected to the inner wall of the weighing block; a first differential gear is fixedly connected to one side of the second gear; a speed-matching gear is rotatably connected to the inner wall of the weighing block; a second differential gear is fixedly connected to one side of the speed-matching gear; and a transmission gear is fixedly connected to one side of the threaded column.

[0009] The rotary shaving cutter has a drive wheel fixedly connected to one side, a support column is slidably connected to the outer wall of the weighing block, a guide groove is provided on the inner wall of the housing, and a driven wheel and a drive wheel are fixedly connected to the outer wall of the support column. The drive wheel and the driven wheel are coupled together by a belt, and the drive wheel and the driven wheel are coupled together by a belt.

[0010] The outer wall of the support column is slidably connected to the inner wall of the guide groove, and the top of the fixed column is in contact with the bottom of the material.

[0011] Wherein, the first differential gear and the gearing gear are meshed, the first gear and the second gear are meshed, and the second differential gear and the transmission gear are meshed.

[0012] The bottom of the fixed column is slidably connected to the outer wall of the base, and the inner wall of the slider is threadedly connected to the outer wall of the threaded column.

[0013] The fixed block is slidably connected to the outer wall of the weighing block, the outer wall of the drive wheel is rotatably connected to the inner wall of the base, and the cross-sectional shape of the guide groove is arc-shaped.

[0014] The outer wall of the gasket is slidably connected to the outer wall of the fixing column, and the cross-sectional shape of the fixing block is L-shaped.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by pulling the weighing block outward, it causes the fixed column to detach from the base support surface. Then, the cylinder on the inner wall of the fixed block is activated. The cylinder's driving force pushes the fixed plate, carrying the pad, to move until the pad is completely separated from the fixed column, releasing the constraint on the fixed column. At this point, the new specification material is slid onto the outer wall of the fixed column. The cylinder is activated again, allowing the pad to re-adhere to the fixed column and press against the material until the material is stably positioned on the fixed column. In this way, the shaving cutter can stably process the new specification material, making the device adaptable to materials of different specifications, greatly improving the overall applicability and meeting the processing needs of multiple types of gears.

[0017] 2. In this utility model, the motor on the starting base drives the shaving cutter to rotate, which in turn drives the first drive wheel to rotate synchronously. Through the transmission of the first belt and the support of the support column, the first driven wheel rotates with the first drive wheel and drives the support column and the second drive wheel to rotate synchronously. The second drive wheel transmits power to the second driven wheel through the second belt, causing it to drive the first gear to rotate. The first gear drives the second gear and the first differential gear to rotate. The first differential gear and the speed-matching gear achieve the first differential speed due to the difference in diameter. Then, the speed-matching gear drives the second differential gear to rotate. The second differential gear and the transmission gear achieve the second differential speed through the difference in diameter, so that the shaving cutter rotates multiple times corresponding to the threaded column rotating once, driving the slider to move slowly. The guide groove ensures that the belt remains taut and stable when pulling the weighing block, improving the operational stability of the device. Attached Figure Description

[0029] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0030] A gear hobbing and shaving follow-up machining device, as shown in the reference. Figure 1 , Figure 3 and Figure 4 The equipment includes a base 1, which provides a stable installation foundation for the entire processing device, ensuring the overall structural stability during operation and preventing vibration from affecting processing accuracy. A housing 2 is fixedly connected to the top of the base 1, which is the core of the equipment's structural frame. A weighing block 6 is slidably connected to the inner wall of the housing 2, facilitating the replacement and positioning of the workpiece. A motor 3 is fixedly connected to the inner wall of the base 1, which provides the core power for the equipment. A shaving cutter 4 is fixedly connected to the drive end of the motor 3, which is the core execution component for gear processing. A transmission mechanism 5 is fixedly connected to the other side of the shaving cutter 4. A threaded column 7 is rotatably connected to the inner wall of the housing 2, and the transmission mechanism 5 transmits the power of the motor 3 to the threaded column 7. A slider 8 is slidably connected to the inner wall of the housing 2, and a fixing mechanism 9 is slidably connected to the outer wall of the housing 2.

[0031] Specifically, the base 1 provides stable support for the device, reduces vibration during operation, and ensures processing accuracy. The housing 2 serves as the structural frame, and the internal weighing block 6 can be flexibly adjusted to assist in the quick positioning and replacement of the workpiece, reducing clamping time. The power output from the motor 3 drives the hobbing cutter 4 to operate, directly performing hobbing and shaving on the gears. On the other hand, it is transmitted to the threaded column 7 through the transmission mechanism 5, causing the threaded column 7 to rotate. The threaded column 7 further drives the slider 8 to slide. Together with the fixing mechanism 9 on the outer wall of the housing 2, they adjust the processing position and the fixed state of the workpiece to ensure a stable and accurate processing process.

[0032] The fixing mechanism 9 includes a fixing block 91 with an L-shaped cross-section. This L-shape design allows it to stably fit the housing 2. A cylinder 92 is fixedly connected to the inner wall of the fixing block 91, providing power for the fixing action. A fixing plate 93 is fixedly connected to the drive end of the cylinder 92, transmitting power from the cylinder 92. A gasket 94 is fixedly connected to one side of the fixing plate 93. A fixing post 96 is fixedly connected to the bottom of the slider 8, and its bottom is slidably connected to the outer wall of the base 1. The fixing post 96 provides mounting support for the material 95, allowing it to be stably fitted onto its outer wall. Simultaneously, it moves with the slider 8 to achieve feeding. The outer wall of the fixing post 96 is slidably connected to... There is material 95. The top of the fixed column 96 and the bottom of the material 95 are in contact. Material 95 is the workpiece to be processed in gear processing. After being sleeved on the fixed column 96 and clamped by the fixing mechanism 9, the gear shape is processed by the rotation of the hobbing cutter 4. The transmission mechanism 5 includes a driven wheel 2 55. The driven wheel 2 55 receives the power transmitted by the driving wheel 2 54 and drives the differential assembly 59 to move. It is the key component for power transmission to the differential assembly 59. The differential assembly 59 is fixedly connected to one side of the driven wheel 2 55. The differential assembly 59 realizes the differential power transmission through the difference in diameter of different gears, so that the hobbing cutter 4 and the threaded column 7 form a speed difference, ensuring that the slider 8 moves slowly to meet the processing requirements.

[0033] Specifically, the L-shaped structure of the fixing block 91 can fit tightly against the shell 2. The internal cylinder 92 drives the fixing plate 93 to move. The gasket 94 on one side of the fixing plate 93 can buffer the clamping force to avoid damaging the material 95. The fixing column 96 provides installation support for the material 95. After the material 95 is placed on it, it moves with the slider 8 to achieve processing feed. When the material 95 is clamped by the fixing mechanism 9, the hobbing cutter 4 can rotate to complete the tooth profile processing. In the transmission mechanism 5, the driven wheel 55 receives power and drives the differential component 59 to operate. The differential component 59 achieves differential transmission by using the diameter difference of different gears, so that the hobbing cutter 4 and the threaded column 7 form a speed difference, allowing the slider 8 to move slowly and accurately match the feed requirements of gear hobbing processing.

[0034] The differential assembly 59 includes a first gear 591, one side of which is fixedly connected to one side of the driven wheel 55. The first gear 591 rotates with the driven wheel 55. A second gear 592 is rotatably connected to the inner wall of the weighing block 6. A first differential gear 593 is fixedly connected to one side of the second gear 592. The second gear 592 meshes with the first gear 591, receives power from the first gear 591, and drives the first differential gear 593 to rotate, realizing the first power transmission and steering. A speed-matching gear 594 is rotatably connected to the inner wall of the weighing block 6. The first differential gear 593 meshes with the speed-matching gear 594, and it meshes with the speed-matching gear 594. The diameter difference of 94 achieves the first differential speed ratio, adjusting the power transmission speed. A second differential gear 595 is fixedly connected to one side of the gear 594. The gear 594 receives the power of the first differential gear 593 and drives the second differential gear 595 to rotate. At the same time, the speed is further adjusted to prepare for the second differential speed. A transmission gear 596 is fixedly connected to one side of the threaded column 7. The second differential gear 595 meshes with the transmission gear 596. The diameter difference between the two achieves the second differential speed ratio, and finally adjusts the speed of the threaded column 7. The threaded column 7 transmits the power after differential speed to the threaded column 7, driving the slider 8 to move.

[0035] Specifically, driven wheel 55 drives the first gear 591 to rotate. The first gear 591 drives the second gear 592 through meshing, which in turn drives the first differential gear 593 to rotate, completing the initial power transmission and steering adjustment. The first differential gear 593 meshes with the speed matching gear 594. The two achieve the first differential ratio by utilizing the diameter difference, and initially adjust the power transmission speed. The speed matching gear 594 synchronously drives the second differential gear 595 to rotate, further optimizing the speed and laying the groundwork for the second differential. Subsequently, the second differential gear 595 meshes with the transmission gear 596, and completes the second differential by utilizing the diameter difference again, accurately adjusting the speed of the threaded column 7. Finally, the threaded column 7 converts the power after differential into the power to drive the slider 8 to move, adapting to the feed rhythm of gear machining.

[0036] Reference Figures 2 to 4A drive wheel 51 is fixedly connected to one side of the shaving cutter 4. The drive wheel 51 rotates synchronously with the shaving cutter 4, transmitting the power of the motor 3 to the driven wheel 52, thus activating the power transmission of the transmission mechanism 5. A support column 57 is slidably connected to the outer wall of the weighing block 6. The support column 57 provides mounting support for the driven wheel 52 and the drive wheel 54, ensuring their synchronous rotation and maintaining stable power transmission as the weighing block 6 moves. A guide groove 58 is provided on the inner wall of the housing 2. The cross-sectional shape of the guide groove 58 is arc-shaped. The outer wall of the support column 57 is slidably connected to the inner wall of the guide groove 58. The guide groove 58 provides a sliding trajectory for the support column 57, ensuring that the support column 57 moves along the arc-shaped trajectory when the weighing block 6 is pulled, maintaining belt tension. Driven wheel 52 and driven wheel 54 are fixedly connected to the outer wall of the support column 57. Driven wheel 52 is coupled to driven wheel 51 via belt 53, receiving power from driven wheel 51 and driving driven wheel 54 to rotate synchronously, thus realizing the intermediate transmission of power. Driven wheel 51 and driven wheel 52 are coupled to driven wheel 52 via belt 53, which transmits power between driven wheel 51 and driven wheel 52, ensuring that their speeds are synchronized and adapting to the movement of the support column 57. Driven wheel 54 and driven wheel 55 are coupled to driven wheel 55 via belt 56, which transmits power between driven wheel 54 and driven wheel 55, thus delivering the power transmitted by the support column 57 to the differential assembly 59, completing the key link of the transmission chain.

[0037] Specifically, when the shaving cutter 4 rotates, it drives the first drive wheel 51 to rotate synchronously. The power is transmitted to the first driven wheel 52 through the first belt 53, starting the power link of the transmission mechanism 5. The support column 57 provides support for the first driven wheel 52 and the second drive wheel 54, so that they rotate synchronously. When the weighing block 6 moves, it can slide along the arc-shaped guide groove 58 on the inner wall of the housing 2 to maintain the belt tension and ensure stable power transmission. After the first driven wheel 52 drives the second drive wheel 54 to rotate, the second drive wheel 54 transmits power to the second driven wheel 55 through the second belt 56. The first belt 53 and the second belt 56 ensure that the speed of each wheel is synchronized while adapting to the movement of the support column 57. Finally, the power is smoothly delivered to the differential component 59, completing the key connection of the transmission link.

[0038] The top of the fixed column 96 contacts the bottom of the material 95, ensuring accurate positioning of the material 95 when it is fitted onto the fixed column 96, and preventing axial displacement of the material 95 during processing from affecting the tooth profile accuracy. The first differential gear 593 and the speed-matching gear 594 are meshed, achieving power transmission and the first differential speed through meshing. The difference in their diameters is used to adjust the rotational speed, providing a basis for the subsequent slow rotational speed of the threaded column 7. The first gear 591 and the second gear 592 are meshed, ensuring stable power transmission from the driven wheel 55 to the first differential gear 593, while changing the direction of power transmission to adapt to the layout of the differential assembly 59. The second differential gear 595 and the transmission gear 596 are meshed, achieving the second differential speed through meshing, further... After reducing the rotational speed, the power is transmitted to the threaded column 7, making the rotational speed of the threaded column 7 much lower than that of the shaving cutter 4, thus meeting the slow feeding requirement of the material 95. The bottom of the fixed column 96 is slidably connected to the outer wall of the base 1. The base 1 provides bottom support for the fixed column 96, ensuring that the fixed column 96 remains stable when moving with the slider 8, and avoiding shaking that affects the processing. The inner wall of the slider 8 is threadedly connected to the outer wall of the threaded column 7. Through the threaded engagement, the rotational motion of the threaded column 7 is converted into the linear motion of the slider 8, realizing the feeding of the material 95 and ensuring that the shaving process can evenly cover the surface of the material 95. The outer wall of the drive wheel 51 is rotatably connected to the inner wall of the base 1. The base 1 provides rotational support for the drive wheel 51, ensuring that the drive wheel 51 rotates stably and avoiding deviation during power transmission.

[0039] Specifically, the top of the fixed column 96 fits against the bottom of the material 95 to ensure accurate positioning when the material 95 is set up, preventing axial displacement during processing from affecting the tooth profile accuracy. Inside the differential assembly 59, the first gear 591 meshes with the second gear 592 to stably transmit power and change direction. The first differential gear 593 meshes with the speed matching gear 594 to achieve the first differential speed through the diameter difference, laying the foundation for slow speed. The second differential gear 595 meshes with the transmission gear 596 to complete the second differential speed, significantly reducing the speed before transmitting it to the threaded column 7, making its speed much lower than that of the hobbing cutter 4, meeting the slow feeding requirements of the material 95. The threaded column 7 and the slider 8 are connected by threads to convert the rotational motion into linear motion, driving the material 95 to feed for uniform processing. The base 1 provides support for the fixed column 96 and the drive wheel 51, ensuring that both run smoothly and avoiding shaking or displacement that could interfere with power transmission and processing accuracy.

[0040] The implementation principle of this application embodiment is as follows: The motor 3 located on the base 1 is started, causing the shaving cutter 4 to rotate under the driving force of the motor 3. This causes the drive wheel 51 to rotate along with the rotation of the shaving cutter 4. Thanks to the transmission of the belt 53 and the support of the support column 57, the driven wheel 52 can rotate along with the support column 57, causing the drive wheel 54 to rotate synchronously. Thanks to the transmission of the belt 56, the driven wheel 55 rotates along with the drive wheel 54, causing the first gear 591 to rotate along with the driven wheel 55. The first gear 591 then drives the second gear 592, which in turn drives the first differential gear 593 to rotate. 3. The speed-matching gear 594 drives the second differential gear 595 to rotate. Due to the different diameters of the first differential gear 593 and the speed-matching gear 594, the rotation is first transmitted with a differential speed ratio. The second differential gear 595 drives the transmission gear 596 to drive the threaded column 7 to rotate. Due to the different diameters of the second differential gear 595 and the transmission gear 596, the rotation is again transmitted with a differential speed ratio. As a result, when the shaving cutter 4 rotates a lot, the threaded column 7 rotates once. This causes the slider 8 to move slowly on the inner wall of the weighing block 6. Thanks to the presence of the guide groove 58, when the weighing block 6 on the inner wall of the housing 2 is pulled outward, the belt 1 53 and the belt 2 56 remain stable, thus greatly improving the operational stability of the entire device.

[0041] When it is necessary to change to a different specification of material 95, pull the weighing block 6 outward, so that the weighing block 6, along with the fixed column 96, detaches from the outer wall of the base 1. Activate the cylinder 92 on the inner wall of the fixed block 91, so that the driving force of the cylinder 92 drives the fixed plate 93 to move the pad 94 until the pad 94 and the fixed column 96 separate. At this time, the material 95 of a different specification slides into the outer wall of the fixed column 96. Activate the cylinder 92 again, so that the pad 94 and the fixed column 96 come into contact with the material 95 until the material 95 remains stable on the outer wall of the fixed column 96. This allows the shaving cutter 4 to stably work on the material 95, thus enabling the entire device to clamp and work with materials 95 of different specifications, greatly improving the applicability of the entire device.

[0042] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
