Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a planetary rotating tooling. Background Art

[0002] When processing workpieces, it is often necessary to rotate a product to complete processing at multiple angles. The traditional method is to process in batches, clamp at different included angles each time, and then rotate the workpiece during subsequent processing. This not only makes the processing cumbersome and inefficient, but also has a large cumulative error.

[0003] For example, a planetary gear rotation positioning mechanism disclosed in the application number: CN202021378221.X. In the utility model, a driving component drives a disc to rotate around a sun gear, and the sun gear drives the workpieces on multiple tooling fixtures to rotate. Through the above settings, the disc rotation can drive the workpiece at the head of the tooling fixture to rotate around itself, and at the same time, the rotation angle of the disc is used to control the rotation angle of the workpiece itself, which is applicable to multi-station assembly and occasions where the fixture needs to rotate around its own axis.

[0004] However, the rotation of the above workpiece itself needs to be controlled by the rotation of the disc. When encountering a scenario where only the workpiece itself needs to rotate, it is very difficult to implement, resulting in the existing device being not flexible enough and difficult to adapt to complex usage environments.

[0028] Embodiment 1 will be described in conjunction with Figure 1 as follows:

[0029] A planetary rotating tooling includes: a bottom plate 1, a workpiece self-rotation driving component 2, a revolution driving component 3, a gearbox 4, a revolving turntable 5, a synchronous driving wheel 6, a synchronous transmission component 7, and a workpiece component 8. The workpiece self-rotation driving component 2 is fixedly installed on the lower side of the bottom plate 1. The output end of the workpiece self-rotation driving component 2 passes through the gearbox 4 and the revolving turntable 5 and is fixedly connected to the synchronous driving wheel 6. The revolution driving component 3 is fixedly installed on the bottom plate 1. The output end of the revolution driving component 3 is fixedly connected to the revolving turntable 5 through the gearbox 4. The synchronous transmission component 7 is fixedly installed on the revolving turntable 5. The synchronous driving wheel 6 is connected to the workpiece component 8 through the synchronous transmission component 7.

[0030] With such a setting, by setting the workpiece self-rotation driving component 2 to drive the synchronous driving wheel 6 to rotate, the workpiece component 8 can be driven to rotate self through the synchronous transmission component 7. By setting the revolution driving component 3, the revolving turntable 5 can be driven to rotate through the gearbox 4.

[0031] Embodiment 2 will be described on the basis of Embodiment 1 in conjunction with Figure 2 as follows:

[0032] The workpiece self-rotation driving component 2 includes: a servo motor 21, a reduction gearbox 22, a coupling 23, a driving shaft 24, and a stable bearing seat 25. The output end of the servo motor 21 is connected to the input end of the reduction gearbox 22. The output end of the reduction gearbox 22 is connected to one end of the driving shaft 24 through the coupling 23. The other end of the driving shaft 24 passes through the stable bearing seat 25 and is fixedly connected to the synchronous driving wheel 6. The stable bearing seat 25 is fixedly connected to the revolving turntable 5.

[0033] The speed reducer 22 can reduce the rotational speed of the servo motor while increasing the output torque, enabling the drive assembly to provide greater driving force to meet the requirements of heavy-load or high-precision driving. The coupling 23 can play a role in shock absorption and compensation for axial and radial displacements between the drive shaft 24 and the speed reducer 22, protecting the drive system from excessive load impacts. The stable bearing seat 25 provides stable support for the drive shaft 24, ensuring the smooth operation of the drive system, reducing vibration, and improving machining accuracy. Fixing the other end of the drive shaft 24 to the synchronous drive wheel 6 and fixing it to the common turntable 5, such a structural design helps to reduce the occupied space and makes the overall structure more compact.

[0034] Embodiment 3, based on Embodiment 2, is described in combination with Figure 3 as follows:

[0035] The revolution drive assembly 3 includes: a reduction motor 31, a mounting plate 32, and a connecting shaft 33. The reduction motor 31 is fixedly installed on the base plate 1. The output end of the reduction motor 31 is fixedly connected to one end of the connecting shaft 33. The other end of the connecting shaft 33 passes through the gearbox 4 and is used in cooperation with the gearbox 4. The gearbox 4 is fixedly connected to the reduction motor 31 through the mounting plate 32.

[0036] The reduction motor 31 increases the output torque by reducing the rotational speed, which is very useful for the revolution motion that requires greater driving force and can effectively drive heavier loads. The mounting plate 32 is used to fix the reduction motor 31 and the gearbox 4, ensuring the stability of the entire drive assembly and reducing vibration during operation. The connecting shaft 33 transmits the power of the reduction motor to the gearbox 4. Since it is fixedly connected, the accuracy and reliability of power transmission can be guaranteed. By directly connecting the reduction motor 31 and the gearbox 4 through the connecting shaft 33, the structural design is compact and space-saving.

[0037] Embodiment 4, based on Embodiment 3, is described in combination with Figure 4 as follows:

[0038] The synchronous drive wheel 6 is fixedly installed at the other end of the drive shaft 24 through a fixing plate 61. Such a setting can improve the installation stability of the synchronous drive wheel 6, and further improve the operation stability of the entire system.

[0039] Embodiment 5, based on Embodiment 4, is described in combination with Figure 5 as follows:

[0040] The synchronous transmission assembly 7 includes four groups of synchronous drive wheels 71, drive wheel brackets 72, three groups of workpiece drive wheels 73, and a synchronous belt 74. The synchronous drive wheels 71 are rotatably arranged on the drive wheel brackets 72. The drive wheel brackets 72 are fixedly installed on the common turntable 5. The synchronous drive wheels 71 are connected to the workpiece drive wheels 73 through the synchronous belt 74. The workpiece drive wheels 73 are connected to the workpiece assembly 8.

[0041] The synchronous drive wheel 71 and the workpiece drive wheel 73 are connected by a synchronous belt 74, which can ensure the synchronization of the movement of the workpiece assembly 8 and the rotation of the common turntable 5. Thus, it is crucial for the machining process that requires precise position control or multi-axis linkage. The drive wheel bracket 72 is fixedly installed on the common turntable 5, providing stable support for the synchronous drive wheel 71, reducing vibration during operation, and improving the stability of transmission. The modular design enables the independent replacement of the synchronous drive wheel 71, the drive wheel bracket 72, and the workpiece drive wheel 73, facilitating maintenance and repair.

[0042] Embodiment Six, based on Embodiment Five, is described in combination with Figure 6 as follows:

[0043] The drive wheel bracket 72 is provided with an oblong adjustment hole 721. With this arrangement, the tightness of the synchronous belt 74 can be adjusted by adjusting the installation position of the oblong adjustment hole 721.

[0044] Embodiment Seven, based on Embodiment Six, is described in combination with Figure 7 as follows:

[0045] The workpiece assembly 8 includes: a workpiece master turntable 81, a connecting frame 82, three groups of mounting flanges 83, and a workpiece 84. The workpiece master turntable 81 is fixedly connected to the common turntable 5 through the connecting frame 82. The mounting flanges 83 are fixedly arranged on the workpiece master turntable 81. The workpiece drive wheel 73 is fixedly connected to one end of a connecting shaft, and the other end of the connecting shaft passes through the mounting flange 83 and is fixedly connected to the workpiece 84.

[0046] Three groups of mounting flanges 83 are arranged on the workpiece master turntable 81, enabling the simultaneous installation of multiple workpieces 84 to achieve multi-station machining and improve production efficiency. The workpiece master turntable 81 is fixedly connected to the common turntable 5 through the connecting frame 82, which can ensure the synchronization of the rotation of the workpiece assembly 8 and the common turntable 5 and maintain machining accuracy. The design of the mounting flanges 83 makes the installation and replacement of the workpiece more convenient and rapid, reducing the production changeover time. The connecting frame 82 provides stable support for the workpiece master turntable 81, ensuring the stability of the workpiece during the machining process and reducing machining errors.

[0047] Working principle of the utility model: During use, the servo motor 21 drives the drive shaft 24 to rotate through the speed reducer 22, thereby driving the synchronous drive wheel 6 to rotate. The synchronous drive wheel 6 drives four groups of synchronous transmission wheels 71 to rotate through the synchronous belt 74. The four groups of synchronous transmission wheels 71 drive three groups of workpiece drive wheels 73 to rotate through the synchronous belt 74, thereby rotating the workpiece 84 and achieving the independent control of the workpiece's self-rotation. The reduction motor 31 drives the connecting shaft 33 to rotate, thereby driving the male turntable 5 to rotate through the gearbox 4. Furthermore, the four groups of synchronous transmission wheels 71 rotate around the axis of the connecting shaft 33, thereby rotating the workpiece 84 and achieving the purpose of simultaneously performing the self-rotation and revolution of the workpiece. The utility model has a reasonable structure, is convenient to use, and has a high degree of automation. It realizes two functions of the self-rotation of the tooling and the simultaneous revolution and self-rotation of the tooling, and can flexibly combine them, greatly reducing the complexity and cost of the traditional structure, and significantly improving the usability and production efficiency.
