Description

[0002] In the field of mechanical manufacturing, double-direction worm gears, as a key transmission component, are widely used in various mechanical equipment requiring bidirectional transmission and precise control of speed and torque, such as industrial robot joints, CNC machine tool feed systems, and precision transmission devices in the aerospace field. The performance of the double-direction worm gear directly affects the operating efficiency, stability, and service life of the entire mechanical system, and the bearing, as the core supporting component of the double-direction worm gear, plays a decisive role in its performance through the quality of its press-fit installation. In the early stages of double-acting worm gear manufacturing, bearing press-in was primarily done manually. Workers used simple tools, such as hammers and copper bars, to tap the bearing into the mounting position on the worm gear. Manual operation made it difficult to precisely control the pressing force and position of the bearing, easily leading to bearing misalignment or inconsistent pressing depth. With the development of mechanical manufacturing technology, some simple mechanical press-in devices emerged. However, different specifications of double-acting worm gears require press-in molds and fixtures of different sizes and specifications. The versatility of simple mechanical press-in devices was poor, and it was difficult to accurately position and adjust the bearing in real time during the press-in process, easily leading to press-in failure or affecting product quality.

The nut is connected to the movable slide table, and the servo motor drives the lead screw to rotate. The rotation is converted into linear motion by the lead screw and nut, which drives the slide table to move. It is also equipped with a bellows cloth / protective cover to protect internal components from dust and impurities, extend service life, and ensure operating accuracy. The helical motion of the lead screw and nut can convert rotational motion into linear motion, which drives the lead screw to rotate through the servo motor. The lead screw drives the movable slide table to move on the guide rails.

[0020] The bidirectional adjustment unit includes a bidirectional lead screw 7, a movable slider 8, a first limiting rod 10, and a first accordion cloth 11. The bidirectional lead screw 7 is rotatably installed inside the side clamping seat 6. Two movable sliders 8 are symmetrically installed on the outside of the bidirectional lead screw 7. The movable sliders 8 are slidably connected to the side clamping seat 6. One side of the movable slider 8 is fixedly connected to the upper and lower clamping plates 9. The first limiting rod 10 is slidably installed inside the movable slider 8. The first limiting rod 10 is fixedly connected to the side clamping seat 6. A first accordion cloth 11 is provided between both sides of the movable slider 8 and the side clamping seat 6. Two movable sliders 8 are driven to move synchronously in opposite directions by a two-way lead screw 7, so as to achieve precise opening and closing of the upper and lower clamping plates 9, adapting to the clamping requirements of two-way worm gears of different diameters. The first limit rod 10 ensures the linear motion stability of the movable slider 8, and the first accordion cloth 11 prevents foreign objects from entering and extends the service life of the equipment.

[0021] Among them, a worm gear 12 is fixedly connected to the outer side of the bidirectional lead screw 7, a worm 13 is rotatably arranged inside the side clamping seat 6, the worm 13 is meshed with the worm gear 12, and a first servo motor 14 is installed inside the side clamping seat 6 by bolts, and the output end of the first servo motor 14 is fixedly connected to the worm 13. Servo motor 14 drives worm gear 13 to rotate. Through the meshing transmission between worm wheel 12 and worm gear 13, the rotational motion is converted into the precise rotation of bidirectional lead screw 7, realizing the automatic adjustment of clamping force. The worm wheel and worm gear structure has self-locking properties, which prevents loosening during clamping and improves processing safety.

[0022] The top support platform 20 has an inner sliding seat 22 that is slidably provided inside. The inner sliding seat 22 has four inner movable slots 24 that are equidistantly opened inside. The inner movable slots 24 are movably connected to an inner adjusting slide plate 25. The inner adjusting slide plate 25 is slidably connected to the top support platform 20. The top of the inner adjusting slide plate 25 is fixedly connected to the top moving seat 28. The outer side of the inner adjusting slide plate 25 is symmetrically fixedly connected to an adjusting rod 26. The inner side of the inner movable slot 24 has symmetrically opened adjusting inclined slots 27 that cooperate with the adjusting rod 26. The adjusting rod 26 is slidably connected to the adjusting inclined slot 27. When cylinder 21 pushes the inner sliding seat 22 to move horizontally, the adjusting rod 26 slides along the adjusting groove 27, driving the inner adjusting slide plate 25 to cause the top moving seat 28 to expand or contract radially, thus realizing the automatic centering and clamping of the inner bearing inner ring by the inner support arc block 36. The groove structure converts linear motion into radial displacement, simplifying the control logic.

[0023] Among them, the top support platform 20 is equipped with a No. 3 cylinder 21 by bolts. The output end of the No. 3 cylinder 21 is fixedly connected to the inner sliding seat 22. Four No. 2 limit slide rods 23 are fixedly connected at equal intervals at the bottom of the inner sliding seat 22. The No. 2 limit slide rods 23 are slidably connected to the top support platform 20. Cylinder 21 provides stable driving force, and limit slide bar 23 restricts the movement trajectory of inner sliding seat 22 to prevent deviation. The two work together to ensure that the four inner support arc blocks 36 on the top support platform 20 move synchronously, so as to achieve uniform force on the inner ring of the bearing and avoid deformation during the pressing process.

[0024] Among them, the inner adjusting slide plate 25 is equipped with a second limiting rod 29, which is fixedly connected to the top support platform 20; The second limiting rod 29 provides secondary guidance to the inner adjusting slide plate 25, forming a double limiting with the adjusting sloping groove 27. This eliminates gaps and vibrations in radial movement, improves the positioning accuracy of the inner support arc block 36, and ensures that the bearing pressing position meets the design requirements.

[0025] The second servo motor 19 is installed inside the adjustment frame 17 by bolts. The output end of the second servo motor 19 is fixedly connected to the top rotating disk 18. The fourth limit slide rod is symmetrically fixed on the adjustment frame 17. The fourth limit slide rod is slidably connected to the support frame 15.

This facilitates the position swapping of the bearings used by the two worm gears and the feeding of the press-in bearings. The fourth limit slide rod restricts the rotation trajectory of the adjustment frame 17 to prevent overshoot and improve the operational flexibility of the equipment.

[0026] Among them, the bottom of the worm gear feeding support 33 is symmetrically fixed with the No. 3 limiting slide rod 34, and the No. 3 limiting slide rod 34 is slidably connected to the side connecting frame 31. The third limiting slide bar 34 guides the worm gear feeding support 33 to ensure that it moves linearly along the side connecting frame 31, avoiding positional deviation during feeding. In conjunction with the fourth cylinder 32, it achieves precise positioning and rapid replacement of the worm gear.

[0027] Among them, four No. 1 limiting slide rods 5 are symmetrically fixed on one side of the side clamping seat 6. The No. 1 limiting slide rods 5 are slidably connected to the inner moving frame 3. A top mounting plate 30 is fixed to the top of one of the support frames 15. Multiple mounting holes are provided on the outer side of the top mounting plate 30. The first limiting slide bar 5 enhances the connection stability between the side clamping seat 6 and the inner moving frame 3, reducing vibration. The top mounting plate 30 provides an expansion interface, through which sensors or auxiliary devices can be quickly integrated to improve the functional expandability of the equipment.

[0028] Among them, the bottom of the support frame 1 is fixedly connected to the bottom support frame 37, which is used to provide overall support for the support frame 1 and the linear module 2; The bottom support frame 37 is made of high-strength material, which distributes the load of the support frame 1 and the linear module 2, reduces the impact of ground vibration on processing accuracy, and its height can be adapted to different production lines, improving the equipment's versatility.

[0029] The support frame 1 serves as the basic support structure for the entire device. Its bottom support frame 37, fixed to the bottom, is made of high-strength material and provides overall support for the support frame 1 and linear modules 2. This distributes the load on the support frame 1 and linear modules 2, reducing the impact of ground vibration on processing accuracy. Its height is adaptable to different production lines, improving equipment versatility. Two linear modules 2 are symmetrically installed inside the support frame 1. Each linear module 2 includes a bracket for mounting guide rails, a sliding table that slides on the guide rails, a lead screw system consisting of a lead screw and nut, and a servo motor driving the lead screw. The nut is connected to the sliding table, and the servo motor drives the lead screw to rotate. The rotation is converted into linear motion via the lead screw and nut, driving the sliding table to move. A bellows cloth / protective cover is also provided to protect internal components from damage. To prevent damage from dust and impurities, extend service life, and ensure operational accuracy, the moving slide of the linear module 2 drives the inner moving frame 3 to move. The inner moving frame 3 is slidably connected to the support frame 1. Four No. 1 limit slide rods 5, symmetrically fixed to one side of the side clamping seat 6, are slidably connected to the inner moving frame 3, enhancing the connection stability between the side clamping seat 6 and the inner moving frame 3 and reducing vibration. No. 1 cylinders 4 are bolted to both sides of the inner moving frame 3. The output end of the No. 1 cylinder 4 is fixedly connected to the side clamping seat 6. The inner arc-shaped clamping groove 35 on the inner side of the side clamping seat 6 is used for initial clamping of the bearing. Two upper and lower clamping plates 9 are symmetrically slidably arranged on the inner side of the side clamping seat 6. The side clamping seat 6 has a bidirectional adjustment part inside, which includes a bidirectional lead screw 7, a moving slider 8, and a No. 1 limit slide rod. The position rod 10, the first accordion cloth 11, and the worm gear 12 are fixedly connected to the outer side of the bidirectional lead screw 7. A worm 13 is rotatably mounted inside the side clamping seat 6, meshing with the worm gear 12. A servo motor 14 is bolted inside the side clamping seat 6, and its output end is fixedly connected to the worm 13. The servo motor 14 drives the worm 13 to rotate, and through the meshing transmission between the worm gear 12 and the worm 13, drives the bidirectional lead screw 7 to rotate. Two symmetrically mounted movable sliders 8 on the outer side of the bidirectional lead screw 7 are slidably connected to the side clamping seat 6, and one side of each movable slider 8 is fixedly connected to the upper and lower clamping plates 9. A first limit rod 10, slidably mounted inside, is fixedly connected to the side clamping seat 6 to ensure the linear motion stability of the movable slider 8. A limit rod is set between the two sides of the movable slider 8 and the side clamping seat 6. The first accordion cloth 11 prevents foreign objects from entering and extends the service life of the equipment. Two moving sliders 8 are driven by a bidirectional lead screw 7 to move synchronously in opposite directions, achieving precise opening and closing of the upper and lower clamping plates 9. This adapts to the clamping requirements of bidirectional worm gears of different diameters and limits the vertical position of the bearings. Support frames 15 are installed above and below the inner moving frame 3. A second cylinder 16 is bolted inside the support frame 15. An adjusting frame 17 is fixedly connected to the output end of the second cylinder 16. A top rotating disk 18 is rotatably mounted on the adjusting frame 17. A second servo motor 19 is bolted inside the adjusting frame 17, and its output end is fixedly connected to the top rotating disk 18. A fourth limiting slide rod is symmetrically fixed to the adjusting frame 17 and is slidably connected to the support frame 15.Servo motor 19 drives the top rotating disk 18 to rotate, realizing the angular adjustment of the top support platform 20. This facilitates the repositioning of the bearings used by the two worm gears and the feeding of the press-fit bearings. Two top support platforms 20 are symmetrically mounted on the top rotating disk 18 via bolts. Four top moving seats 28 are equidistantly slidably arranged on the top support platform 20. Inner support arc blocks 36 are bolted to the outer side of each top moving seat 28. An inner sliding seat 22 is slidably arranged inside the top support platform 20. Four second-level limit sliding rods 23 are equidistantly fixed to the bottom of the inner sliding seat 22. The second-level limit sliding rods 23 are slidably connected to the top support platform 20 to limit the movement trajectory of the inner sliding seat 22 and prevent deviation. A third cylinder 21 is bolted inside the top support platform 20. The output end is fixedly connected to the inner sliding seat 22 to provide stable driving force. The inner sliding seat 22 has four equidistant inner movable slots 24. An inner adjusting slide plate 25 is movably connected inside each inner movable slot 24. The inner adjusting slide plate 25 is slidably connected to the top support platform 20. The top of the inner adjusting slide plate 25 is fixedly connected to the top moving seat 28, and adjusting rods 26 are symmetrically fixedly connected to its outer side. Adjusting inclined slots 27, which cooperate with the adjusting rods 26, are symmetrically opened on the inner side of the inner movable slots 24. The adjusting rods 26 are slidably connected to the adjusting inclined slots 27. When the third cylinder 21 pushes the inner sliding seat 22 to move horizontally, the adjusting rods 26 slide along the adjusting inclined slots 27, driving the inner adjusting slide plate 25 to cause the top moving seat 28 to expand or contract radially, thus achieving automatic centering and clamping of the inner ring of the bearing by the inner support block 36. The inner sliding frame 25 has a second limiting rod 29, which is fixedly connected to the top support platform 20. This provides secondary guidance for the inner adjusting slide plate 25 and forms a double limit with the adjusting inclined groove 27, eliminating gaps and vibrations in radial movement, improving the positioning accuracy of the inner support arc block 36, and ensuring that the bearing pressing position meets the design requirements. A side connecting frame 31 is provided on one side of the inner moving frame 3. The structure where the worm gear 13 is located is presumably incorrect in the original description. Based on the previous text, it should be another suitable structure. However, according to the original structure, a fourth cylinder 32 is installed internally by bolts. The output end of the fourth cylinder 32 is fixedly connected to a worm gear feeding support 33. A third limiting slide rod 34 is symmetrically fixed to the bottom of the worm gear feeding support 33. The third limiting slide rod 34 is slidably connected to the side connecting frame 31 for feeding the worm gear. Support 33 guides the movement of the bearing along the side connecting frame 31, preventing positional deviation during loading. It works in conjunction with cylinder 32 to achieve precise positioning and rapid replacement of the worm gear. A top mounting plate 30 is fixed to the top of one of the support frames 15. Multiple mounting holes on the outer side of the top mounting plate 30 provide expansion interfaces, allowing for the rapid integration of sensors or auxiliary devices, thus enhancing the equipment's functional expandability. During operation, the moving slide of the linear module 2 drives the inner moving frame 3 and the clamped bearings for loading and unloading. The inner arc-shaped clamping groove 35 on the inner side of the side clamping seat 6 initially clamps the bearings. The upper and lower clamping plates 9 limit the vertical position of the bearings. The top moving seat 28 and the inner support arc block 36 provide internal support and fixation for the bearings.The output of servo motor 19 drives the top rotating disk 18 to rotate, thereby reversing the positions of the two top support platforms 20 to facilitate bearing loading. Then, the upper and lower sets of bearings are press-fitted bidirectionally, completing the bearing pressing process in the bidirectional worm gear machining.
