[0034] like Figure 1 , Figure 2 and Figure 3The stabilizing mechanism is not directly fixed on the fixing frame 1. There are two fixing frames 1 connected to the external device. The support block 3 and the fixing block 4 are aligned together in the vertical direction, and there are openings on the support block 3 and the fixing block 4 to facilitate the passage of the connecting screw 5. The first threaded locking sleeve 6 and the second threaded locking sleeve 7 are located at both ends of the support block 3 and the fixing block 4 away from each other.

[0035] A thin-walled component 2 is arranged above the two stabilizing mechanisms, and the stabilizing mechanism pair is arranged on both sides of the bottom of the thin-walled component 2 to provide support for the thin-walled component 2.

[0036] like Figure 1 The thin-walled component 2 is a tubular component, and the load-bearing wheel 12 in the stabilizing mechanism is used to provide load-bearing for the thin-walled component 2 .

[0037] A rectangular connecting plate 13 is fixedly installed on one side of the fixing block 4 by bolts, and a movable notch 14 is opened on the rectangular connecting plate 13. A T-shaped guide plate 15 is fixedly installed on one side of the supporting block 3 by bolts, and the T-shaped guide plate 15 and the movable notch 14 are slidably connected.

[0038] like Figure 3 and Figure 4 By utilizing the sliding connection between the T-shaped guide plate 15 and the movable notch 14, the movement of the rectangular connecting plate 13 can be guided so that the rectangular connecting plate 13 can only move up and down in the vertical direction.

[0039] A movable seat 16 is slidably connected to the fixing frame 1, a support plate 17 is arranged on the top of the movable seat 16, and stabilizing blocks 18 are fixedly connected to both sides of the support plate 17.

The auxiliary block 21 is provided with screw holes, which can realize threaded connection with the bolts to fix one end of the inclined connecting plate 22 to the auxiliary block 21.

[0043] An adjusting vertical plate 24 is fixedly mounted on one end of the connecting block 23 by bolts, an adjusting block 25 is arranged on one side of the adjusting vertical plate 24 and below the connecting block 23 , and an adjusting pressure wheel 26 is rotatably connected to one side of the adjusting block 25 .

[0044] like Figure 1 and Figure 5 The adjusting pressing wheel 26 does not directly contact the thin-walled component 2, making the movement of the thin-walled component 2 more convenient.

[0045] The adjusting block 25 is provided with an adjusting screw 27, both ends of which pass through the adjusting block 25 and the connecting block 23 respectively and are threadedly connected with a third locking sleeve 28, a third locking nut 29 is threadedly connected on the adjusting screw 27 and located on the top of the adjusting block 25, an adjusting sleeve 30 is threadedly connected on the adjusting screw 27, and a pressure spring 31 is fixedly connected between the adjusting sleeve 30 and the bottom of the connecting block 23.

[0046] A horizontally movable machining tool 32 is disposed on one side of the thin-walled component 2 , and the machining tool 32 is used to machine the inside of the thin-walled component 2 .

[0047] like Figure 1 The external telescopic rod or other equipment in the prior art can drive the processing tool 32 to move horizontally, so that the processing tool 32 can move to the inside of the thin-walled component 2, and the inside of the thin-walled component 2 can be processed while the thin-walled component 2 rotates.

[0048] The fixing frame 1 is fixedly connected with a support rod 33 , a motor fixing seat 34 is fixedly installed on the top of the support rod 33 , a servo motor 35 is fixedly installed on the top of the motor fixing seat 34 , and a driving ring 36 is fixedly connected to the output end of the servo motor 35 .

[0049] like Figure 1 The servo motor 35 is connected to an external power source and has a corresponding control switch on the outside. The motor fixing seat 34 provides support for the servo motor 35, and the servo motor 35 drives the driving ring 36 to rotate.

[0050] The driving ring 36 is provided with three locking mechanisms in a ring array, and the locking mechanism includes an adjusting groove 37 opened on the driving ring 36, and a locking screw 38 is rotatably connected to the inner wall of the adjusting groove 37, and a movable pressure block 39 is threadedly connected to the locking screw 38 and located in the adjusting groove 37, and one side of the movable pressure block 39 is fixedly connected to a locking plate 40, and one side of the locking plate 40 is provided with an arc-shaped locking groove 41 used in conjunction with the thin-walled component 2.

[0051] like Figure 1 and Figure 6 When one end of the thin-walled component 2 is pressed against the driving ring 36, the locking screw 38 can be rotated clockwise to drive the movable pressure block 39 to move, and the movable pressure block 39 drives the locking plate 40 to move together, so that the locking plates on the three locking mechanisms move in a direction close to each other, and the arc-shaped locking groove 41 on the locking plate 40 is attached to the thin-walled component 2, and one end of the thin-walled component 2 is locked on the driving ring 36, so that when the servo motor 35 drives the driving ring 36 to rotate, the driving ring 36 drives the thin-walled component 2 to rotate, and at this time, the processing tool 32 is driven by the external device to move to the inside of the thin-walled component 2 to process the thin-walled component 2;

[0052] On the contrary, the locking screw 38 is rotated counterclockwise to drive the movable pressing block 39 to move, and the movable pressing block 39 can drive the locking plates 40 to separate from each other, so that the processed thin-walled component 2 can be removed from the driving ring 36.

[0053] The working principle of a stable anti-vibration mechanism for processing thin-walled parts provided by the present invention is as follows:

[0054] When the thin-walled component 2 needs to be processed, one end of the thin-walled component 2 is first fixed to the driving ring 36. At this time, the two bearing wheels 12 are located on both sides of the bottom of the thin-walled component 2 to provide positioning and support for the bottom of the thin-walled component 2.

[0055] Then loosen the bolts between the auxiliary block 21 and the inclined connecting plate 22, and the angle of the inclined connecting plate 22 can be rotated and adjusted. The inclined connecting plate 22 drives the adjusting vertical plate 24 to move through the connecting block 23, and the adjusting vertical plate 24 drives the adjusting pressing wheel 26 to move through the adjusting block 25. The adjusting pressing wheel 26 can approach and press the top of the thin-walled component 2, and press and position the thin-walled component 2 from the top, and then fix the auxiliary block 21 and the inclined connecting plate 22 together;

[0056] On the contrary, when the bolts between the auxiliary block 21 and the inclined connecting plate 22 are loosened, the inclined connecting plate 22 can be adjusted to drive the adjusting vertical plate 24 and the adjusting pressure wheel 26 to move away from the thin-walled component 2, so that a new thin-walled component 2 can be easily removed or fixed.

[0057] Compared with the related art, the stable anti-vibration mechanism for processing thin-walled parts provided by the present invention has the following beneficial effects:

[0058] The present invention uses two load-bearing wheels 12 to support the bottom of the thin-walled component 2 when processing the thin-walled component 2, and then uses an adjusting pressure wheel 26 to press the top of the thin-walled component 2, so as to provide support and positioning for the end of the thin-walled component 2 away from the driving ring 36, thereby reducing the vibration generated by the end of the thin-walled component 2 away from the driving ring 36 during the processing, avoiding the tool vibration when the processing tool 32 processes the thin-walled component 2 from the inside, and improving the processing accuracy of the thin-walled component 2 and the service life of the processing tool 32.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
