Description

Technical Field

[0001] The utility model relates to the technical field of electric spindle processing, in particular to a rotary mechanism of an electric spindle processing platform. Background Art

[0002] The electric spindle is a new technology that has emerged in the field of CNC machine tools, integrating the machine tool spindle with the spindle motor. The spindle is a set of components, which includes the electric spindle itself and its accessories: the electric spindle, high-frequency frequency conversion device, oil mist lubricator, cooling device, built-in encoder, tool changer, etc. This transmission structure form of "integrating the spindle motor and the machine tool spindle into one" makes the spindle component relatively independent from the transmission system and overall structure of the machine tool, so it can be made into a "spindle unit", commonly known as "electric spindle". The characteristics are high speed, high precision, low noise, and the structure with a lock on the inner ring is more suitable for spray lubrication.

[0003] Through patent search, it was found that a slewing mechanism of an electric spindle machining platform with a publication number of CN212239853U can drive the outer gear turntable to rotate through the telescopic effect of the hydraulic rod. When the hydraulic rod is working, it can only drive the bar rod to move to the specified position. By changing the telescopic length of the bar rod, the number of rotations of the outer gear turntable can be changed through the transmission mechanism, so that the degree of machining and welding will not be too hard and the welding depth will not be too deep, and the electric spindle will not be caused external damage. The machining quality of the electric spindle is guaranteed by this transmission mechanism, but its transmission mechanism is exposed to the outside, and dust and debris are easily attached to the surface of the transmission mechanism, which increases the workload of subsequent maintenance and cleaning, and its transmission mechanism can only drive the center disc to reciprocate, which is relatively inconvenient to use when the electric spindle needs to be ground and cut and the center disc needs to rotate continuously. For this reason, we propose a slewing mechanism of an electric spindle machining platform to solve or improve the above problems. Utility Model Content

[0020] See also Figure 1-6, including a device housing 1, a support leg 2 is fixed at the bottom of the device housing 1, and a plurality of support legs 2 are symmetrically fixed at the bottom of the device housing 1, and the plurality of support legs 2 are used to support the device body and ensure the stability of the device during operation, and a central shaft 7 is rotatably installed inside the device housing 1 through a bearing, and a rotating table 3 is fixed on the top of the central shaft 7, and a clamping assembly is arranged on the top of the rotating table 3. The structure of the clamping assembly is the same as that of the comparative document, and its structure and function are not described in detail here. When the central shaft 7 rotates, the fixed rotating table 3 is driven to rotate, and a second gear 11 fixed on the surface of the central shaft 7 is driven to rotate. When the second gear When the wheel 11 rotates, it will drive the fixed central shaft 7 to rotate. The support column 8 is fixed to the top of the second gear 11.

When the support column 8 rotates, it will drive the fixed connecting plate 14 to rotate. The limiting rod 9 is inserted into the inside of the connecting plate 14. The limiting rod 9 is symmetrically inserted with two groups inside a group of connecting plates 14. The top of the connecting plate 14 is fixed with a limiting plate, and the limiting plate can adjust the position of the limiting rod 9. The limit rod 9 is limited to prevent the limit rod 9 from detaching from the bottom side of the connecting plate 14. A receiving groove is provided at the bottom of the rotating table 3 at a position on the top side of the limit rod 9. The limit rod 9 can be inserted into the inside of the receiving groove. When the connecting plate 14 rotates, the inserted limit rod 9 will be driven to rotate. The spring 10 is sleeved on the surface of the limit rod 9. The gear ring 12 is fixed to the bottom of the limit rod 9. One end of the spring 10 contacts the bottom of the connecting plate 14, and the other end contacts the top of the gear ring 12. When the gear ring 12 moves, it squeezes the gear ring 12 to deform and drive the limit rod 9 to move. When the limit rod 9 rotates, it drives the fixed gear ring 12 to rotate. The gear ring 12 is located at the first The gear ring 12 is meshed with the second gear 11 on one side of the second gear 11. When the gear ring 12 rotates, it will drive the meshed second gear 11 to rotate. The guide slope 15 is fixed to the bottom of the gear ring 12. When the gear ring 12 rotates, it will drive the fixed guide slope 15 to rotate. A driving motor 6 is fixed inside the equipment housing 1. A first gear 5 is fixed on the top of the output shaft of the driving motor 6. The driving motor 6 can drive the first gear 5 fixed on the top of the output shaft to rotate. The first gear 5 is located on one side of the gear ring 12 and meshed with the gear ring 12. When the first gear 5 rotates, it will drive the meshed gear ring 12 to rotate. The adjustment component is arranged inside the equipment housing 1.

[0021] The adjusting component includes a connecting rod 19 inserted into the device housing 1, a second threaded rod 18 fixed on the surface of the connecting rod 19, when the connecting rod 19 rotates, it drives the second threaded rod 18 fixed on the surface to rotate, a third gear 17 installed inside the device housing 1 through a bearing, the third gear 17 is meshed and connected with the second threaded rod 18, when the second threaded rod 18 rotates, it drives the meshed third gear 17 to rotate, a first threaded rod 16 inserted inside the third gear 17, the first threaded rod 16 is threadedly connected with the third gear 17, when the third gear 17 rotates, it drives the threaded first threaded rod 16 to move, an adjusting push rod 13 fixed to the top of the first threaded rod 16, when the first threaded rod 16 moves, it drives the fixed adjusting push rod 13 to move, the top of the adjusting push rod 13 contacts the bottom of the guide slope 15, when the adjusting push rod 13 moves, it drives the contacted guide slope 15 to move, so that the guide slope 15 drives the fixed gear ring 12 to move, the bottom of the guide slope 15 is set as an inclined surface, and the top of the adjusting push rod 13 is set to fit the guide The inclined surface at the bottom of the guide slope 15 will squeeze the top of the adjusting push rod 13 through the inclined surface when the guide slope 15 rotates, so that the guide slope 15 moves and drives the fixed gear ring 12 to move. When the gear ring 12 moves to a certain position, it will be out of meshing connection with the first gear 5, so that the first gear 5 can no longer drive the gear ring 12 to rotate. At the same time, the spring 10 will push the gear ring 12 to move, so that the gear ring 12 squeezes the top of the adjusting push rod 13 through the guide slope 15, so that the inclined surface of the adjusting push rod 13 and the pressure of the spring 10 can be adjusted. The guide slope 15 is rotated and drives the gear ring 12 to rotate. During the rotation process, the height of the gear ring 12 will gradually change due to the inclined design of the guide slope 15. When the gear ring 12 moves to a certain height, the gear ring 12 will resume the meshing connection state with the first gear 5 and the second gear 11, so that the first gear 5 can continue to drive the second gear 11 to rotate through the gear ring 12. The adjusting hand wheel 4 is fixed to one end of the connecting rod 19, and the other end of the connecting rod 19 is rotatably installed on the inner surface of the equipment housing 1 through the rotating shaft.

[0022] Working principle: when the electric spindle needs to be processed, the electric spindle is placed on the top of the rotating table 3, and the rotating table 3 is clamped and fixed by the clamping assembly. At this time, the adjusting hand wheel 4 can be turned to drive the connecting rod 19 to rotate. When the connecting rod 19 rotates, it drives the second threaded rod 18 to rotate. When the second threaded rod 18 rotates, it drives the third gear 17 to rotate, so that the third gear 17 drives the first threaded rod 16 to move. When the first threaded rod 16 moves, it drives the fixed adjusting top rod 13 to move, so that the adjusting top rod 13 drives the top contact guide slope 15 to move. When the guide slope 15 moves, it drives the fixed gear ring 12 to move, so that the initial height of the gear ring 12 changes. When the gear ring 12 moves, the contact area with the guide slope 15 will change. When the gear ring 12 moves, the contact area between the gear ring 12 and the first gear 5 will decrease, so that the driving motor 6 drives the first gear 5 to rotate, and the first gear 5 drives the gear ring 1 2 rotates, the gear ring 12 drives the guide slope 15 to rotate and drives the guide slope 15 to move through the adjusting push rod 13. When the guide slope 15 drives the gear ring 12 to move, the gear ring 12 is more quickly disengaged from the meshing connection with the first gear 5, thereby adjusting the rotation angle of the second gear 11. When the rotating table 3 needs to rotate continuously, the height of the adjusting push rod 13 is adjusted by adjusting the hand wheel 4, so that the adjusting push rod 13 does not contact the bottom of the guide slope 15, so that the driving motor 6 can drive the first gear 5 to rotate, so that the first gear 5 drives the gear ring 12 and the second gear 11 to rotate continuously, and the second gear 11 drives the rotating table 3 to rotate continuously through the central rotating shaft 7, which is relatively convenient to use. At the same time, because the gear ring 12, the second gear 11, the driving motor 6 and the driving motor 6 are arranged inside the equipment housing 1, it can be avoided that the external dust and debris are easily attached to the surface due to their exposure, thereby reducing the workload of subsequent maintenance and cleaning, and the use is relatively convenient.
