Detailed implementation manners

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Referring to Figures 1 to 5 , the present invention provides a technical solution: a five-axis turntable with a deceleration control structure, including a mounting seat 4. The mounting seat 4 is circular. A mounting table 5 is provided on the top of the mounting seat 4. A groove plate or a fixture is provided on the top of the mounting table 5. The fixture is a three-jaw chuck, a four-jaw chuck, etc., and the top of the groove plate is also used to mount the fixture.

[0025] A second housing 3 is provided at the bottom of the mounting seat 4. As Figure 5 shown, a plurality of feet are provided at the top edge of the second housing 3. The feet are detachably connected to the bottom of the mounting seat 4. The feet and the bottom of the mounting seat 4 are specifically fastened by bolts, so that it is convenient to install the second housing 3 under the mounting seat 4. A sealing cover 18 is detachably provided at the bottom of the second housing 3. The edge of the sealing cover 18 and the bottom of the second housing 3 are also fastened by bolts, so that it is convenient to open the second housing 3 for maintenance of its interior.

[0026] A second transmission mechanism connected to the mounting table 5 is provided inside the second housing 3. The second drive motor 2 located outside the second housing 3 is connected to the mounting table 5 through the second transmission mechanism. As Figure 5 shown, the second transmission mechanism includes a second worm gear 25 parallel to and located below the mounting seat 4. The second worm gear 25 is coaxially installed on the drive shaft 21. The top of the drive shaft 21 is rotatably connected to the top of the second housing 3. Specifically, the drive shaft 21 extends above the mounting seat 4 and is vertically connected to the mounting table 5, so that the mounting table 5 can be fixed to the second transmission mechanism;

[0027] As Figure 5 shown, one side of the second worm gear 25 meshes with the second worm 24. The two ends of the second worm 24 are rotatably connected to the second housing 3. The second drive motor 2 is arranged on the side of the second housing 3, and the second drive motor 2 is located at one end of the second worm 24. The rotating shaft of the second drive motor 2 extends into the second housing 3. Bevel gears 23 are provided on both the rotating shaft of the second drive motor 2 and one end of the second worm 24. The two bevel gears 23 mesh with each other. Therefore, when the second drive motor 2 rotates, the second drive motor 2 can drive the second worm 24 to rotate through the two meshing bevel gears 23. The second worm 24 will drive the second worm gear 25 to rotate. Finally, the second worm gear 25 drives the drive shaft 21 and the mounting table 5 to rotate, so that the groove plate or fixture located on the top of the mounting table 5 rotates;

[0028] It should be noted that the diameter of the bevel gear 23 on the second drive motor 2 is smaller than the diameter of the bevel gear 23 on the second worm 24. In this way, the torque of the second drive motor 2 can be amplified in sequence through the two bevel gears 23 and the worm and worm gear, so as to drive a workpiece with a larger mass to rotate.

[0029] Furthermore, a support arm 7 is provided on one side of the mounting seat 4. The end of the support arm 7 far from the mounting seat 4 is connected to the first transmission mechanism. The first transmission mechanism is arranged inside the first housing 11. The first drive motor 13 located outside the first housing 11 is connected to the support arm 7 through the first transmission mechanism. As Figure 4 shown, the first transmission mechanism includes a first worm gear 16 located inside the first housing 11. The first worm gear 16 is perpendicular to the mounting seat 4. The first worm gear 16 is coaxially installed on the mounting shaft 17. The two ends of the mounting shaft 17 are respectively rotatably connected to the first housing 11. One end of the mounting shaft 17 is connected to the support arm 7;

[0030] The bottom of the first worm gear 16 meshes with the first worm 19. The two ends of the first worm 19 are respectively rotatably connected to the first housing 11. A second transmission gear 20 is provided at one end of the first worm gear 16. The second transmission gear 20 meshes with the first transmission gear 22 above it. The first transmission gear 22 is installed on the rotating shaft of the first drive motor 13. The first drive motor 13 is installed on the side of the first housing 11;

[0031] It should be noted that the diameter of the first transmission gear 22 on the first drive motor 13 is smaller than the diameter of the second transmission gear 20 on the first worm 19. In this way, the torque output by the first drive motor 13 can be amplified twice in sequence through the first worm 19, the second transmission gear 20, and the worm and gear, so as to drive a workpiece with a larger mass to swing.

[0032] Based on the above embodiments, there is lubricating oil for lubricating the gears in both the first housing 11 and the second housing 3. In order to filter and clean the lubricating oil in the two housings, during use, the second housing 3 and the first housing 11 are connected by a pipeline, and a circulation pump 15 and a filter 9 are provided on this pipeline. The filter 9 is a lubricating oil filter. When the filter 9 is opened, the internal filter element can be replaced. The provided circulation pump 15 is used to drive the lubricating oil to circulate in the second housing 3 and the first housing 11 in sequence. During the circulation of the lubricating oil, the metal debris generated by the gear meshing will be filtered by the filter 9, so that the circulating lubricating oil can be cleaned, avoiding the metal debris from entering between the gears and accelerating wear. At the same time, the flowing lubricating oil can also flow better on the surfaces of each gear.

[0033] Furthermore, during actual use, a single support arm 7 can also support the mounting seat 4. In order to enable the mounting seat 4 to have greater support strength, the number of support arms 7 is designed to be two and they are symmetrically installed on the side of the mounting seat 4. A support 6 is provided at the end of the support arm 7 away from the first housing 11, and a support shaft (as indicated by the arrow A in Figure 5 ) is provided at the end of this support arm 7. The support 6 is rotatably connected to the support shaft. And both the support 6 and the bottom of the first housing 11 are mounted on the support base 12, and the two support bases 12 are connected by a strip-shaped seat 1. A plurality of mounting holes are provided on the strip-shaped seat 1. During use, the mounting holes can be fastened to the machine tool with bolts;

[0034] As Figure 1 shown, a plurality of feet are provided at the bottom edge of the first housing 11. The feet are detachably connected to the support base 12, and the feet and the support base 12 are specifically fastened with bolts. The top of the first housing 11 is detachably provided with a cover 8, and the edge of the cover 8 and the top of the first housing 11 are also fastened with bolts.

[0035] Based on the above embodiments, it can be further optimized that the bottom of the support 6 is also fastened to the support base 12 with bolts.

[0036] Based on the above embodiments, it can be further optimized that a flow meter or a hydraulic sensor 10 is also provided on the pipeline between the second housing 3 and the first housing 11, which is used to sense the flow or pressure of the lubricating oil passing through the filter 9. The flow meter or the hydraulic sensor 10 is connected to an alarm through a controller, and an alarm prompt is given when the flow or pressure changes.

[0037] Based on the above embodiments, further optimization can be carried out. Both between the support arm 7 and the mounting shaft 17 and between the support arm 7 and the support shaft (as indicated by the arrow A in Figure 5 ) are connected by a flange 14.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
