[0002] The internal gear ring is an important component of the planetary gear. Its inner circumference is equipped with multiple transmission teeth that mesh with the planetary gears. After the internal gear ring is hobbing or gear shaping process, the tooth sides or end faces of the internal gear ring blank will have different degrees of flanging or burrs. This requires the use of an internal gear ring blank processing device to grind and remove the burrs.

[0003] In the gear manufacturing process, precise positioning of the gear to be processed is a key step to ensure machining accuracy and consistency. However, commonly used positioning devices are often complex in structure, requiring special fixtures and auxiliary centering equipment. The cost of the entire system is high, which is not conducive to the promotion and application of small and medium-sized enterprises. At the same time, existing positioning mechanisms are mostly set up independently, requiring separate operation from the main processing equipment. The clamping steps are cumbersome, time-consuming, and dependent on manual adjustment, resulting in low positioning efficiency. Due to improper control of the mating clearance or inconsistent benchmarks, poor positioning accuracy and repeatability are often caused, affecting the tooth profile, tooth direction and meshing quality of the gear, and in severe cases, even causing batch scrap.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1 to 4 This utility model provides a technical solution: An internal gear ring blank processing device for easy positioning includes a base plate 1, a support arm 2 fixedly installed on the upper end face of the base plate 1, a sleeve 3 fixedly installed at the end of the support arm 2, a threaded rod 6 rotatably connected inside the sleeve 3, a blank ring 4 sleeved on the outer surface of the sleeve 3, a motor 5 fixedly installed at the left end of the sleeve 3, the output shaft of the motor 5 fixedly connected to the threaded rod 6, a threaded sleeve 7 helically driven on the right side of the outer surface of the threaded rod 6, a connecting rod 10 rotatably connected to the outer surface of the threaded sleeve 7, a slide rail 9 starting from the side of the connecting rod 10, a support shaft 8 slidably connected inside the slide rail 9, the support shaft 8 fixedly connected to the sleeve 3, a threaded sleeve 11 helically driven in the middle of the outer surface of the threaded rod 6, a groove 12 starting from the outer surface of the sleeve 3, a fixed rod 13 slidably connected inside the groove 12, a limit ring 14 provided on the left side of the blank ring 4, and the fixed rod 13 fixedly installed between the threaded sleeve 11 and the fixed rod 13.

[0017] First, the blank ring 4 is placed on the sleeve 3. Then, the motor 5 is started to make the threaded rod 6 rotate. The threaded sleeve 7 and the threaded sleeve 11 on the outer surface of the threaded rod 6 will move towards each other. The threaded sleeve 7 is rotatably connected to the connecting rod 10. The slide rail 9 on the connecting rod 10 has a support shaft 8 slidably connected inside. The support shaft 8 is fixedly connected to the sleeve 3. Therefore, when the threaded sleeve 7 is displaced, it will drive the connecting rod 10 to deflect, so that the support shaft 8 slides inside the slide rail 9. The other end of the connecting rod 10 will be raised. The three sets of connecting rods 10 are raised synchronously and abut against the blank ring 4. The displacement of the threaded sleeve 11 will drive the limiting ring 14 to move through the fixed rod 13 and abut against the blank ring 4 synchronously. The connecting rod 10 will fix and limit the blank ring 4. The lower side of the outer surface of the sleeve 3 has a second groove 15. A push plate 16 is provided on the lower side of the sleeve 3. The push plate 16 extends into the interior of the sleeve 3 through the second groove 15 and is connected to the threaded rod 6 by a helical drive. The push plate 16 is slidably connected to the second groove 15.

[0018] An airbag 18 is fixedly installed on the outer surface of the sleeve 3, and a top plate 19 is fixedly installed on the outer surface of the airbag 18.

[0019] Both the second airbag 18 and the roof plate 19 are provided with three sets, which are arranged in a ring-shaped dispersion.

[0020] An airbag 17 is fixedly installed between the push plate 16 and the support arm 2, and three sets of airbags 18 are connected to the airbag 17 by a connecting pipe.

[0021] The threaded groove on the outer surface of the threaded rod 6 is provided in three sections. The two sets of threaded grooves on the left are the same and are set in a mirror image with the threaded groove on the right.

[0022] Secondly, the push plate 16, which is connected to the screw rod 6 by a helical drive, will move towards the motor 5, thereby squeezing the first airbag 17. This causes the gas inside the first airbag 17 to enter each group of second airbags 18 through the connecting pipe, causing the second airbags 18 to expand. This drives the top plate 19 to abut against the inner wall of the blank ring 4, providing internal support and positioning for the blank ring 4, and further improving the stability of the blank ring 4.

[0023] In gear manufacturing, precise positioning of the gear to be processed is a crucial step in ensuring machining accuracy and consistency. However, commonly used positioning devices are often complex in structure, requiring specialized fixtures and auxiliary centering equipment, resulting in high system costs and hindering their widespread adoption by small and medium-sized enterprises. Furthermore, existing positioning mechanisms are mostly independent, requiring separate operation from the main processing equipment. The clamping process is cumbersome, time-consuming, and reliant on manual adjustments, leading to low positioning efficiency. Improper control of the mating clearance or inconsistent references often results in poor positioning accuracy and repeatability, affecting the gear's tooth profile, tooth direction, and meshing quality, and in severe cases, even causing batch scrap. Therefore, this invention achieves rapid positioning and secure clamping of the blank ring 4 on the processing equipment by setting up a dedicated fixing device. The device has a certain degree of versatility, adapting to the fixing requirements of blank rings 4 of different specifications, reducing reliance on high-precision pre-positioning, and is suitable for mass production, significantly improving the automation level and production efficiency of gear processing.

[0024] Working principle: First, the blank ring 4 is placed on the sleeve 3. Then, the motor 5 is started to make the threaded rod 6 rotate. The threaded sleeve 7 and the threaded sleeve 11 on the outer surface of the threaded rod 6 will move towards each other. The threaded sleeve 7 is rotatably connected to the connecting rod 10. The slide rail 9 on the connecting rod 10 has a support shaft 8 slidably connected inside. The support shaft 8 is fixedly connected to the sleeve 3. Therefore, when the threaded sleeve 7 is displaced, it will drive the connecting rod 10 to deflect, so that the support shaft 8 slides inside the slide rail 9. The other end of the connecting rod 10 will be raised. The three sets of connecting rods 10 are raised synchronously and abut against the blank ring 4. The displacement of the threaded sleeve 11 will drive the limiting ring 14 to move through the fixed rod 13 and abut against the blank ring 4 synchronously. The connecting rod 10 will fix and limit the blank ring 4. Secondly, the push plate 16, which is connected to the screw rod 6 by a helical drive, will move towards the motor 5, thereby squeezing the first airbag 17. This causes the gas inside the first airbag 17 to enter each group of second airbags 18 through the connecting pipe, causing the second airbags 18 to expand. This drives the top plate 19 to abut against the inner wall of the blank ring 4, providing internal support and positioning for the blank ring 4, and further improving the stability of the blank ring 4.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
