Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a highly stable hydraulic rotary machining device for large machine tools. Background Technology

[0002] Heavy-duty lathes are classified as follows: machine tools weighing between 10 and 30 tons are large machine tools; those weighing between 30 and 100 tons are heavy machine tools; and those weighing over 100 tons are ultra-heavy machine tools. Heavy-duty machine tools refer to metal cutting machine tools listed in the large machine tool catalog. Large machine tools require the use of a hydraulic rotary platform.

[0003] Existing hydraulic rotary platforms typically utilize planetary reducers, cycloidal pinwheel reducers, and worm gear reducers for transmission during production. However, these methods are not stable enough for use on large machine tools, and it is inconvenient to use two worm gears for transmission. This results in low stability of the hydraulic rotary platform during use, thereby reducing the practicality of the device. Therefore, this utility model proposes a high-stability hydraulic rotary machining device for large machine tools to solve the above problems. Utility Model Content

The worm wheel is installed in the middle position inside the bottom cavity and meshes with one side of the first worm and the second worm, respectively. A transmission rod is installed above the worm wheel, and the top end of the transmission rod extends to the top of the cover plate and is connected to the bottom end of the mounting cavity.

The limiting groove is opened inside the cover plate, and the limiting block is provided inside the limiting groove. The top end of the limiting block is connected to the bottom end of the mounting cavity.

[0008] A further improvement is that two limiting blocks are provided inside the limiting groove, and the two limiting blocks are distributed at equal intervals inside the limiting groove.

[0009] A further improvement is made in that: the clamping mechanism includes a servo motor, a drive gear, a rotating plate, transmission teeth, a spiral rail, a clamping block, a fixed groove, a movable block, and a guide structure. The servo motor is installed at the front end of the mounting cavity, the drive gear is installed inside the mounting cavity, and the output end of the servo motor is connected to one end of the drive gear.

[0012] The beneficial effects of this utility model are as follows: By setting a rotary mechanism inside the bottom cavity, the rotation of the mounting cavity can be driven by the cooperation of the first hydraulic motor, the first worm, the worm wheel, the second hydraulic motor, the second worm, the limiting groove, and the limiting block of the rotary mechanism, thereby driving the workpiece to rotate.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a highly stable hydraulic rotary machining device for large machine tools, including a bottom cavity 1, a cover plate 2 installed above the bottom cavity 1, a rotary mechanism disposed inside the bottom cavity 1, an mounting cavity 3 installed above the cover plate 2, and a clamping mechanism disposed inside the mounting cavity 3.

[0020] The rotary mechanism includes a first hydraulic motor 4, a first worm 5, a worm wheel 6, a second hydraulic motor 7, a second worm 8, and a limiting structure. The first hydraulic motor 4 is installed on one side of the front end of the bottom cavity 1, and the second hydraulic motor 7 is installed on the other side of the front end of the bottom cavity 1. The first worm 5 is installed on one side inside the bottom cavity 1, and the output end of the first hydraulic motor 4 is connected to one end of the first worm 5. The second worm 8 is installed on the other side inside the bottom cavity 1, and the output end of the second hydraulic motor 7 is connected to one end of the second worm 8. The worm wheel 6 is installed at the middle position inside the bottom cavity 1, and the worm wheel 6 meshes with one side of both the first worm 5 and the second worm 8. A transmission rod is installed above the worm wheel 6. The top of the rod extends above the cover plate 2, and the top of the transmission rod is connected to the bottom of the mounting cavity 3. In use, the first hydraulic motor 4 and the second hydraulic motor 7 are started simultaneously, causing the first hydraulic motor 4 to rotate forward and the second hydraulic motor 7 to rotate in reverse, respectively driving the first worm 5 and the second worm 8 to rotate in opposite directions. Since the first worm 5 and the second worm 8 are both meshed with the worm wheel 6, the worm wheel 6 is driven to rotate. Then, under the limitation of the limiting groove 9 and the limiting block 10, the mounting cavity 3 is driven to rotate by the worm wheel 6, thereby driving the workpiece to rotate. The rotation of the worm wheel 6 driven by the first worm 5 and the second worm 8 makes the workpiece more stable during processing, thus greatly improving the stability of the device during use.

[0021] The limiting structure includes a limiting groove 9 and a limiting block 10. The limiting groove 9 is opened inside the cover plate 2, and the limiting block 10 is arranged inside the limiting groove 9. The top end of the limiting block 10 is connected to the bottom end of the mounting cavity 3. There are two limiting blocks 10 arranged inside the limiting groove 9, and the two limiting blocks 10 are evenly distributed inside the limiting groove 9. In use, the mutual cooperation between the limiting groove 9 and the limiting block 10 can limit the mounting cavity 3 when it rotates, making the mounting cavity 3 more stable when rotating.

[0022] The clamping mechanism includes a servo motor 11, a drive gear 12, a rotating plate 13, transmission gears 14, a spiral rail 15, a clamping block 16, a fixed groove 17, a movable block 18, and a guide structure. The servo motor 11 is installed at the front end of the mounting cavity 3, and the drive gear 12 is installed inside the mounting cavity 3. The output end of the servo motor 11 is connected to one end of the drive gear 12. The rotating plate 13 is installed inside the mounting cavity 3, and the transmission gears 14 are installed on the outer side below the rotating plate 13. The drive gear 12 and the transmission gears 14 mesh with each other. The spiral rail 15 is installed above the rotating plate 13, and the clamping block 16 is installed above the spiral rail 15. The clamping block 16 has a spiral groove below it that matches the spiral rail 15. The fixed groove 17 is opened inside the mounting cavity 3. A movable block 18 is provided, one end of which is connected to the outer side of the rotating plate 13. In use, the workpiece is placed above the mounting cavity 3, and then the servo motor 11 is started to drive the drive gear 12 to rotate. Since the drive gear 12 meshes with the transmission gear 14, the transmission gear 14 is driven to rotate. Under the limitation of the fixed groove 17 and the movable block 18, the transmission gear 14 drives the rotating plate 13 to rotate, which in turn drives the spiral rail 15 to rotate. Since the clamping block 16 is provided with a thread that matches the spiral rail 15, under the limitation of the guide rail 19 and the guide groove 20, the clamping block 16 is driven to move, and the position of the workpiece is fixed by the clamping block 16. At this time, the workpiece can be processed, making the workpiece more stable during processing, thereby greatly improving the practicality of the device in use.

[0023] The guiding structure includes a guide rail 19 and a guide groove 20. The guide rail 19 is installed inside the mounting cavity 3. The clamping block 16 has guide grooves 20 on both sides. The guide rail 19 is disposed inside the guide groove 20. The cross-section of the guide rail 19 is smaller than the cross-section of the guide groove 20. The guide rail 19 and the guide groove 20 form a sliding structure. In use, the mutual cooperation between the guide rail 19 and the guide groove 20 can guide the clamping block 16 when it moves, making the clamping block 16 more stable when it moves.

[0024] Working principle: The operator first places the workpiece above the mounting cavity 3, then starts the servo motor 11 to drive the drive gear 12 to rotate. Since the drive gear 12 meshes with the transmission gear 14, it drives the transmission gear 14 to rotate. Then, under the limitation of the fixed groove 17 and the movable block 18, the transmission gear 14 drives the rotating plate 13 to rotate, which in turn drives the spiral rail 15 to rotate. Since the clamping block 16 has a thread that matches the spiral rail 15, under the limitation of the guide rail 19 and the guide groove 20, it drives the clamping block 16 to move. Then, the clamping block 16 is used to fix the position of the workpiece, and the workpiece can be processed at this time. When the workpiece needs to be rotated, the first hydraulic motor 4 and the second hydraulic motor 7 are started at the same time, so that the first hydraulic motor 4 rotates forward and the second hydraulic motor 7 rotates in reverse, respectively driving the first worm 5 and the second worm 8 to rotate in opposite directions. Since the first worm 5 and the second worm 8 are meshed with the worm wheel 6, the worm wheel 6 is driven to rotate. Then, under the limit of the limiting groove 9 and the limiting block 10, the worm wheel 6 drives the mounting cavity 3 to rotate, thereby driving the workpiece to rotate.
