Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, specifically a rotary gear shaping bearing device. Background Technology

[0002] Gear shaping is a forming method that uses a gear-shaped or rack-shaped cutting tool (gear shaper) and a workpiece (gear blank) to mesh at a certain transmission ratio to cut and machine the tooth profile of a gear. It can be seen as simulating the meshing transmission of a pair of gears, where one "gear" (gear shaper) is very hard and has a cutting edge, and replicates its tooth profile by cutting the other, softer "gear" (workpiece) in a reciprocating motion.

[0003] Currently, most existing gear shaping bearing devices use a single-stage method to place gear blanks for shaping, resulting in only one gear blank being placed in a single shaping operation. Furthermore, these devices are not suitable for processing gear blanks of various sizes, which not only affects the applicability of the device but also reduces the efficiency of gear shaping. Therefore, a rotary gear shaping bearing device needs to be designed. Summary of the Invention

[0004] To address the aforementioned issues, and to resolve the problems of existing gear shaping bearing devices that mostly use a single-stage loading and unloading method for gear blanks, resulting in only one gear blank being loaded per shaping operation, and the inability to process gear blanks of various sizes, this invention provides a rotary gear shaping bearing device. This device effectively separates and simultaneously performs gear blank loading and unloading from gear blank shaping, ensuring the gear blank is more stable after being positioned. Furthermore, the device is suitable for shaping gear blanks of various sizes and can simultaneously and independently shape multiple gears of different sizes, thus improving the efficiency of gear blank shaping and ensuring the quality of the finished gears.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary gear hobbing bearing device, comprising a base support assembly, the base support assembly supporting a first circumferential rotating assembly, the first circumferential rotating assembly driving a linear drive assembly to reciprocate circumferentially between the material feeding point and the gear hobbing point, the linear drive assembly driving a second circumferential rotating assembly to perform horizontal linear movement, the second circumferential rotating assembly driving a gear limiting assembly to perform circumferential rotation and cooperating with an external gear hobbing device to complete the gear hobbing operation, the gear limiting assembly limiting and fixing the position of the gear blank.

[0006] The aforementioned rotary gear shaping bearing device includes a bottom support assembly comprising a bottom support plate, wherein a support column is provided on the outer wall of the bottom surface of the bottom support plate.

[0007] The aforementioned rotary gear hobbing bearing device includes a first circumferential rotating component comprising a first drive motor, the first drive motor being detachably connected to the outer wall of the bottom surface of the base plate, the output shaft of the first drive motor being connected to one end of a first rotating shaft, and the other end of the first rotating shaft being detachably connected to a support plate, wherein a support hole is provided on the upper surface of the support plate.

[0008] The aforementioned rotary gear hobbing bearing device includes a linear drive assembly comprising a servo motor detachably connected to the inner wall of a support plate.

A ball nut is provided on the outer wall of the lead screw. A slider is detachably connected to the outer wall of the ball nut. A limit hole is formed on the outer wall of the slider, and a limit rod is provided on the inner wall of the support hole. The outer wall of the limit rod is slidably connected to the inner wall of the limit hole. A side groove is formed on the outer wall of the slider away from the servo motor.

[0009] In the aforementioned rotary gear hobbing bearing device, the second circumferential rotating component includes a second drive motor, which is detachably connected to the inner wall of the top surface of the side groove, and the output shaft of the second drive motor is connected to the lower end of the second rotating shaft.

[0010] The aforementioned rotary gear shaping bearing device includes a gear limiting assembly comprising a bearing plate, the outer wall of the bottom surface of the bearing plate being detachably connected to the upper end of the second rotating shaft, a bearing rod being provided on the upper surface of the bearing plate, and a slot being provided on the outer wall of the bearing rod, and a threaded groove being provided on the upper surface of the bearing rod; a screw is threadedly connected to the inner wall of the threaded groove, and the screw is provided on the outer wall of the bottom surface of the cover plate.

[0011] In the aforementioned rotary gear shaping bearing device, there are multiple limiting rods and limiting holes, and the multiple limiting rods are symmetrically distributed on the inner sidewall of the support hole.

[0012] In the aforementioned rotary gear hobbing bearing device, the number of the support holes, linear drive components, second circumferential rotation components, and gear limiting components are all multiple, and the multiple support holes are symmetrically distributed on the upper surface of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) First, move the gear blank and wedge the inner sidewall of the gear blank with the inner sidewall of the slot. Then move the cover plate and align the screw with the opening end of the threaded groove and rotate it so that the gear blank can be clamped in the middle position between the bearing rod and the cover plate under the action of the cover plate. Then, the first drive motor drives the first rotating shaft to rotate, thereby driving the support plate to rotate in a circle. Then, the gear blank clamped on the bearing plate can be placed in the working area of ​​the external gear shaping equipment.

Moreover, the gear blank after the limiting is more stable, which not only improves the gear blank shaping processing efficiency, but also ensures the product quality of the finished gear.

[0014] (2) The servo motor drives the lead screw to rotate, which in turn drives the slider to move linearly inside the support hole under the action of the ball nut and the inner side wall of the limit hole sliding along the outer side wall of the limit rod. Then, the gear blank can be placed in the gear shaping area according to the size of the gear blank. Then, the second drive motor drives the second rotating shaft to rotate, which drives the gear blank to rotate in a circle.

Example

[0017] Depend on Figures 1-7 This invention discloses a rotary gear shaping support device, comprising a base support assembly 1, which supports a first circumferential rotating assembly 2. The first circumferential rotating assembly 2 drives a linear drive assembly 3 to reciprocate circumferentially between the material feeding point and the gear shaping point.

The gear blank is relatively stable after being limited. The device is also suitable for shaping gear blanks of various sizes and can simultaneously and independently shape gears of various sizes.

[0018] Specifically, the bottom support assembly 1 includes a bottom support plate 101, and a support column 102 is provided on the outer wall of the bottom surface of the bottom support plate 101. The bottom support assembly 1 provides support for the first circumferential rotation assembly 2.

[0019] Specifically, the first circumferential rotation assembly 2 includes a first drive motor 201, which is detachably connected to the outer wall of the bottom surface of the bottom support plate 101. The output shaft of the first drive motor 201 is connected to one end of a first rotating shaft 202, and the other end of the first rotating shaft 202 is detachably connected to a support plate 203. The upper surface of the support plate 203 is provided with a support hole 204. The first drive motor 201 drives the first rotating shaft 202 to rotate, thereby driving the support plate 203 to rotate circumferentially, which in turn allows the gear blank clamped on the bearing plate 501 to be placed into the working area of ​​the external gear shaping equipment.

[0020] Specifically, the linear drive assembly 3 includes a servo motor 301, which is detachably connected to the inner wall of the support plate 203. The output shaft of the servo motor 301 is connected to one end of a lead screw 302, and the other end of the lead screw 302 is rotatably connected to the inner wall of the support hole 204. A ball nut 303 is provided on the outer wall of the lead screw 302. A slider 304 is detachably connected to the outer wall of the ball nut 303. A limit hole 307 is provided on the outer wall of the slider 304. The support hole 204 contains... A limiting rod 306 is provided on the side wall, wherein the outer side wall of the limiting rod 306 is slidably connected to the inner side wall of the limiting hole 307; a side groove 305 is provided on the outer side wall of the slider 304 away from the servo motor 301. The servo motor 301 drives the lead screw 302 to rotate, thereby driving the slider 304 to move linearly inside the support hole 204 under the action of the ball nut 303 and the inner side wall of the limiting hole 307 sliding along the outer side wall of the limiting rod 306, so that the gear blank can be placed in the gear shaping area according to the size of the gear blank.

[0021] Specifically, the second circumferential rotation assembly 4 includes a second drive motor 401, which is detachably connected to the inner wall of the top surface of the side groove 305. The output shaft of the second drive motor 401 is connected to the lower end of the second rotating shaft 402. The second drive motor 401 drives the second rotating shaft 402 to rotate, thereby driving the gear blank to rotate circumferentially. In turn, with the cooperation of the external gear shaping equipment, the gear shaping operation can be completed.

[0022] Specifically, the gear limiting assembly 5 includes a support plate 501. The outer wall of the bottom surface of the support plate 501 is detachably connected to the upper end of the second rotating shaft 402. A support rod 502 is provided on the upper surface of the support plate 501, and a slot 503 is provided on the outer wall of the support rod 502. A threaded groove 506 is provided on the upper surface of the support rod 502. A screw 505 is threadedly connected to the inner wall of the threaded groove 506, and the screw 505 is provided on the outer wall of the bottom surface of the cover plate 504. By moving the gear blank and wedging the inner wall of the gear blank with the inner wall of the slot 503, and then moving the cover plate 504 and aligning the screw 505 with the opening end of the threaded groove 506, the gear blank can be clamped in the middle position between the support rod 502 and the cover plate 504 under the action of the cover plate 504.

[0023] Specifically, there are multiple limiting rods 306 and multiple limiting holes 307, and the multiple limiting rods 306 are symmetrically distributed on the inner sidewall of the support hole 204. The multiple limiting rods 306 make the linear movement of the slider 304 more stable.

[0024] Specifically, there are multiple support holes 204, linear drive assembly 3, second circumferential rotation assembly 4 and gear limiting assembly 5, and multiple support holes 204 are symmetrically distributed on the upper surface of support plate 203. With multiple gear limiting assemblies 5 symmetrically distributed on support plate 203, gear blanks can be loaded and unloaded while gear blanks are being shaped.

[0025] In use, firstly, the gear blank is moved and its inner wall is wedged with the inner wall of the slot 503. Then, the cover plate 504 is moved and the screw 505 is aligned with the opening end of the threaded groove 506. After rotation, the gear blank is clamped between the support rod 502 and the cover plate 504 under the action of the cover plate 504. Next, the first drive motor 201 drives the first rotating shaft 202 to rotate, which in turn drives the support plate 203 to rotate circumferentially. This allows the gear blank clamped on the support plate 501 to be placed in the working area of ​​the external gear shaping equipment. At the same time, with multiple gear limiting components 5 symmetrically distributed on the support plate 203, the gear blank can be loaded and unloaded while the gear shaping operation is performed. This effectively realizes the function of separating and simultaneously performing the loading and unloading of gear blanks and the gear shaping operation. Moreover, the gear blank is more stable after being limited, which not only improves the gear shaping efficiency but also ensures the finished product. The gear's product quality is then improved. The servo motor 301 drives the lead screw 302 to rotate, which, under the action of the ball nut 303 and the inner wall of the limiting hole 307 sliding along the outer wall of the limiting rod 306, drives the slider 304 to move linearly within the support hole 204. This allows the gear blank to be positioned in the gear shaping area according to its size. The second drive motor 401 then drives the second rotating shaft 402 to rotate, causing the gear blank to rotate circumferentially. With the cooperation of an external gear shaping device, the gear shaping operation is completed. Simultaneously, multiple linear drive components 3, a second circumferential rotation component 4, and a gear limiting component 5 arranged in parallel on the support plate 203 can simultaneously perform gear shaping operations on gears of various sizes. This effectively enables the device to perform gear shaping operations on gear blanks of various sizes and to simultaneously and independently shape gears of various sizes, improving the device's applicability.
