[0002] At present, the MTT gear milling turntable is an important device for processing parts on a shield machine, such as the processing of annular teeth. It not only improves the processing efficiency but also enhances the processing accuracy. After the blank is fixed on the processing table, the processing equipment on the processing table is driven to move towards the blank to complete the hole opening or tooth slot processing of the part. In this process, ensuring the stability of the processing equipment is crucial, which directly affects the processing quality and the finished product rate.

[0003] In related technologies, to ensure the stability of the processing equipment, the commonly adopted solutions mainly include two forms: one is to install a traction chain similar to a drag chain on the side wall of the processing equipment, and use the interaction of each segment of the traction chain to fix the processing equipment; the other method is to adjust the mechanical locking device under the processing equipment to make it tightly connected to the processing table, thereby restricting the movement tendency of the processing equipment. These means can play a fixing effect to a certain extent and improve the processing accuracy.

[0004] For the above-mentioned related technologies, there are the following defects: there are gaps between the nodes of the traction chain, and the resonance generated by the interaction between the nodes during the processing will affect the processing accuracy. Utility Model Content

[0045] Refer to Figure 1 and Figure 2, A vibration damping and clamping mechanism for a milling machine, including a processing table 1, a processing device 11 and a telescopic mechanism 4. The processing device 11 is arranged above the processing table 1 and is slidably connected to the processing table 1. A plurality of first dovetail slide rails 12 are provided between the processing device 11 and the processing table 1. The plurality of first dovetail slide rails 12 are parallel to each other, and a slidably connected first dovetail slider 13 is provided on each first dovetail slide rail 12. The first dovetail slider 13 is installed on the processing device 11. The plurality of first dovetail slide rails 12 are arranged parallel to each other, which can ensure the stability of the processing device 11 when sliding along the processing table 1. The sliding connection between the first dovetail slider 13 and the first dovetail slide rail 12 improves the accuracy and smoothness of the processing device 11 when sliding. One end of the telescopic mechanism 4 is connected to the processing table 1, and the other end is used to abut against the processing device 11.

The processing table 1 is used to carry and fix the processing device 11 to ensure that the processing device 11 can slide on the processing table 1. The processing device 11 slides on the processing table 1 to adjust to a suitable position for processing. One end of the telescopic mechanism 4 is connected to the processing table 1, and the other end is used to abut against the processing device 11 to limit the sliding of the processing device 11 and avoid resonance during the processing. Generally, the vibration damping and clamping mechanism improves the stability of the processing device 11 and effectively reduces the resonance phenomenon during the processing.

[0047] Referring to Figure 1 and Figure 2 , a first positioning mechanism 2 is provided on the processing table 1 on the side of the processing device 11. The first positioning mechanism 2 includes a telescopic member 21, a first bearing plate 22, a pressure sensor 23, and a second bearing plate 24.

In the length direction of the first dovetail slide rail 12, the telescopic member 21, the first bearing plate 22, the pressure sensor 23, and the second bearing plate 24 are connected in sequence. The second bearing plate 24 is arranged between the pressure sensor 23 and the processing device 11. The end of the telescopic member 21 away from the first bearing plate 22 is installed on the processing table 1. After the processing device 11 moves to the processing position, it can just abut against the second bearing plate 24, so that the second bearing plate 24 detects the pressure, and thus the precise alignment between the processing device 11 and the processing table 1 can be realized, ensuring the stability of the processing device 11 during the processing. The setting of the telescopic member 21 facilitates the correction of the position of the second bearing plate 24.

[0048] Referring to Figure 1 and Figure 2, a second positioning mechanism 3 is provided between the processing device 11 and the processing table 1.

The infrared emitter 31 is installed on the processing device 11, and the infrared receiver 32 is installed on the processing table 1 for receiving the infrared rays emitted by the infrared emitter 31. After the processing device 11 moves to the processing position, the infrared rays emitted by the infrared emitter 31 are exactly received by the infrared receiver 32, thereby enabling precise alignment between the processing device 11 and the processing table 1, ensuring the stability of the processing device 11 during the processing, and further reducing the resonance phenomenon during the processing.

The second toothed plate 413 is installed on the processing device 11. A first hydraulic cylinder 411 is connected between the first toothed plate 412 and the processing table 1. After the processing device 11 moves to the processing position, the first hydraulic cylinder 411 drives the first toothed plate 412 to move towards the second toothed plate 413, so that the first toothed plate 412 abuts against the second toothed plate 413 and is mutually locked, effectively limiting the sliding of the processing device 11, improving the stability during the processing, and avoiding the resonance phenomenon.

At this time, the processing device 11 abuts against the second bearing plate 24, the pressure sensor 23 just detects the pressure, and the infrared rays emitted by the infrared emitter 31 are just received by the infrared receiver 32. The dual position detection can realize the precise alignment between the processing device 11 and the processing table 1, ensuring the stability of the processing device 11 during the processing process.

[0053] After the processing device 11 moves to the processing position, the first hydraulic cylinder 411 drives the first toothed plate 412 to move towards the second toothed plate 413, so that the first toothed plate 412 abuts against the second toothed plate 413 and is stuck to each other, effectively limiting the sliding of the processing device 11 and improving the stability during the processing process, avoiding the resonance phenomenon.
