Description

Technical Field

[0001] This utility model relates to the field of rotary table technology, and more specifically, to a high-precision rotary table for machining centers. Background Technology

[0002] In the current technology, the high-precision rotary tables commonly used in the market still have limitations in structural design, making it difficult to achieve convenient rotation of the table body. Traditional rotary tables often adopt a manual driving rotation method, which is cumbersome to operate, not only increasing the operator's workload, but also potentially affecting the processing accuracy of the workpiece due to errors in the operation process.

[0003] Secondly, the existing rotary table has an unreasonable design in its bottom fixed structure, making the installation and disassembly process cumbersome and the adjustment and locking process complicated, requiring the use of professional tools. This not only affects the installation efficiency but also reduces the flexibility and mobility of the equipment. In some specific working conditions, such as when it is necessary to quickly change the processing station or adjust the installation position of the rotary table, the traditional structure cannot achieve this quickly, which greatly reduces the flexibility of the entire production line.

[0004] Furthermore, current high-precision rotary tables generally lack effective workpiece fixing components, making it impossible to efficiently and safely fix the parts to be processed. During high-speed or high-precision machining, if the workpiece is not firmly fixed, it is very easy for the workpiece to shift, vibrate, or fall off, which not only affects the processing quality but may also cause equipment damage or personnel safety accidents.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a high-precision rotary table for machining centers, which has the following advantages:

[0018] 1. The core of the rotary assembly is that the second motor drives the drive gear, which in turn drives the driven gear to rotate. This gear meshing transmission method can ensure that the angle adjustment of the rotary table is accurate and stable, which is especially suitable for high-precision machining tasks. During the rotation, the placement plate and the support table are connected by the sliding cooperation of the guide wheels, which further improves the stability and consistency of the rotation, thereby reducing the error caused by uneven rotation or jamming.

[0019] 2. The design of the support components provides an effective means of fixing the rotary table. During use, the fixing sleeve can slide and adjust along the support column to ensure that the bottom of the rotary table is stably supported when adjusted to the appropriate position. Combined with the adjustment function of the threaded rod, the position of the support seat can be precisely adjusted according to actual needs to ensure that the rotary table is always in a stable state and avoids vibration or displacement caused by insufficient bottom support, thereby maintaining high machining accuracy.

[0020] 3. The clamping assembly uses a first motor to drive a bidirectional threaded rod, which precisely controls the movement of the clamping block. This design ensures that the clamping block can clamp the workpiece evenly and stably, avoiding workpiece displacement or loosening due to improper clamping. The sliding of the clamping block and the cooperation of the moving block make the clamping process smoother, ensuring that the workpiece will not shift due to vibration or other reasons during processing, greatly improving the processing accuracy.

[0030] Please see Figures 1-5 A high-precision rotary table for a machining center includes a table body 1. A rotary assembly is provided on the table body 1. The rotary assembly includes a support platform 2, a second motor 3, a coupling 4, a drive gear 5, and a driven gear 6. The support platform 2 is fixedly installed on the table body 1. The second motor 3 is installed at one end of the support platform 2. The coupling 4 is connected to the output end of the second motor 3. The drive gear 5 is installed on the coupling 4. The driven gear 6 is meshed with the drive gear 5. A support assembly is provided at the bottom of the table body 1. The support assembly includes a support column 7, a fixed sleeve 8, and a support rod 9. The support column 7 is located at the bottom of the table body 1. The fixed sleeve 8 is slidably connected to the support column 7. The support rod 9 is detachably installed on the fixed sleeve 8.

[0031] A placement plate 10 is mounted on the driven gear 6, and the placement plate 10 is rotatably connected to the support platform 2.

[0032] Guide wheels 11 are evenly installed on the support platform 2, and the guide wheels 11 are slidably connected to the bottom of the placement plate 10.

[0033] The support column 7, the fixing sleeve 8 and the support rod 9 are connected by a first threaded rod 12, and the bottom of the support rod 9 is connected by a second threaded rod 13.

[0034] A support seat 14 is installed at the bottom of the second threaded rod 13.

[0035] In this embodiment, when the platform 1 needs to be rotated during use, the second motor 3 is started, which drives the drive gear 5 to rotate via the coupling 4 at the output end. During rotation, the drive gear 6 meshes with the drive gear 5 and rotates, which in turn drives the placement plate 10 to rotate. During rotation, the plate 10 rotates along the guide wheel 11 on the support platform 2 mounted on the platform 1, thus facilitating angle adjustment. In order to secure the bottom, the fixing sleeve 8 is slid along the support column 7. After sliding to the appropriate position, the first threaded rod 12 passes through one end of the support rod 9 and then through the fixing sleeve 8 to connect with the support column 7, thus securing the platform. Then, the second threaded rod 13 is rotated along the support rod 9 to adjust the platform to the appropriate position, where the support base 14 at the bottom provides support.

[0036] Please see Figure 4 As an embodiment of a high-precision rotary table for a machining center, a clamping assembly is provided on a placement plate 10. The clamping assembly includes a first motor 15, a bidirectional threaded rod 16, and a clamping block 17. The first motor 15 is fixedly installed on the placement plate 10, the bidirectional threaded rod 16 is connected to the output end of the first motor 15, and the clamping block 17 is slidably connected to the placement plate 10.

[0037] Movable blocks 18 are installed at both ends of the clamping block 17. One end of the movable block 18 is threadedly connected to the bidirectional threaded rod 16. A guide block 19 is installed on the placement plate 10.

[0039] More specifically, during use, after the part to be processed is placed on the placement plate 10, the first motor 15 is started, which drives the bidirectional threaded rod 16 at the output end to rotate. During the rotation, the clamping block 17 on it moves along the bidirectional threaded rod 16 using the moving block 18 on it. Meanwhile, the moving block 18 at the other end slides along the guide groove 20 on the guide block 19. After it slides to the appropriate position, it stops, thus completing the clamping and fixing process of the part.

[0040] In summary, during the use or operation of the overall equipment: When it is necessary to rotate the platform 1, the second motor 3 is started, which drives the drive gear 5 to rotate via the coupling 4 at the output end. During this rotation, the driven gear 6 meshes with it and rotates, which in turn drives the placement plate 10 to rotate. During this rotation, the plate rotates along the guide wheel 11 on the support platform 2 installed on the platform 1, thus facilitating angle adjustment. In order to fully fix the bottom during use, the fixing sleeve 8 is slid along the support column 7. After it slides to the appropriate position, the first threaded rod 12 passes through one end of the support rod 9, and then passes through the fixing sleeve 8 to connect with the support column 7, thus completing the fixation process. Then, the second threaded rod 13 is threaded along the support rod 9 to adjust it to the appropriate position, and then the bottom support seat 14 provides support.

[0041] During use, after the part to be processed is placed on the placement plate 10, the first motor 15 is started, which drives the bidirectional threaded rod 16 at the output end to rotate. During the rotation, the clamping block 17 on it moves along the bidirectional threaded rod 16 using the moving block 18 on it. Meanwhile, the moving block 18 at the other end slides along the guide groove 20 on the guide block 19. After it slides to the appropriate position, it stops, thus completing the clamping and fixing process of the part.
