[0013] A method for processing a magnesium-aluminum light alloy thin-walled cylindrical tube, using the above-mentioned vibration-damping support device for processing a magnesium-aluminum light alloy thin-walled cylindrical tube, comprises the following steps:

[0014] Step 1. Screw the inner ends of the four bracket screws into the four threaded through holes on the center bracket respectively, adjust the extension length of the bracket screw according to the diameter of the part to keep the extension length consistent. After the adjustment is completed, tighten the thread locking groove on the center bracket with screws to fix the bracket screw;

[0034] The structure of the present invention is further described below with reference to the accompanying drawings and by way of examples. It should be noted that the present examples are descriptive rather than restrictive.

[0035] A vibration-damping support device for machining thin-walled cylindrical tube parts made of magnesium-aluminum light alloy, see Figure 1-Figure 8 The invention point is: it consists of three parts: a central bracket 1, an airbag bracket group 2 and an inflatable airbag 3. The central bracket is a square frame, and is connected to four groups of airbag bracket groups through bracket screws using four threaded through holes; each group of airbag bracket groups is composed of a bracket screw, an opening and closing nut, an airbag bracket, a locking slider and an opening and closing connector; the airbag bracket group and the central bracket are fixedly connected radially through the bracket screw. The outer end of the bracket screw is connected to the airbag bracket through a spherical hinge and locked by a nut; after the airbag bracket and the locking slider are matched, the distance between the two can be adjusted to adapt to thin-walled workpieces of different widths, and at the same time, the airbag pressure can be controlled to adhere to the inner hole wall of the processed part to enhance the vibration reduction effect.

[0036] The specific structure of each part is as follows:

[0037] Center bracket:

[0038] like Figure 3 and Figure 4 As shown, the overall shape is a square frame, and the elements are symmetrical. Specifically, a boss 1.1 is provided in the middle of the outer side of each side of the square frame, and a threaded through hole 1.2 is vertically provided on each boss and the corresponding frame. The threaded through hole is used to cooperate with the support screw of the airbag support group, and the support screw can be rotated to control the extension length of the screw. In order to achieve the locking of the support screw after it is adjusted into place. A threaded locking groove 1.5 is provided between the boss and the outer surface of the corresponding frame (details are shown in FIG. Figure 2 As shown, two screw through holes 1.3 are arranged on the boss on one side of the threaded locking groove, and two threaded holes 1.4 corresponding to the two screw through holes on the boss are arranged on the frame on one side of the threaded locking groove. By tightening the screws in the screw through holes on the boss and the corresponding threaded holes on the frame, the boss on one side of the threaded locking groove is elastically deformed, pressing the threaded side wall of the bracket screw rod to produce a locking effect, thereby locking the bracket screw rod.

[0039] Airbag stent kit:

[0040] It includes a support screw 2.1 and a split nut 2.2. Figure 5 It is a schematic diagram of the support screw and the split nut, where the left end is the support screw and the right end is the split nut.

[0041] The outside of the support screw is composed of threads, and a spherical socket 2.1.2 is provided inside the outer end, and the cross-section diameter of the outer end face of the spherical socket is smaller than the diameter of the spherical socket. The spherical socket is used to cooperate with the ball head at the inner end of the airbag support. Six elastic deformation grooves 2.1.1 are provided on the outer end to evenly divide the circumference. Due to the above design, when the two are installed, the ball head is aligned with the spherical socket and pressure is applied. When the pressure reaches a certain value, the outer end of the support screw can be elastically deformed. After the ball head fits with the spherical socket, the outer end of the support screw returns to its original state. After the installation is completed, the ball head can rotate freely. After the two are matched, the ball head extends into the spherical socket. At this time, when the opening and closing nut is twisted to the "open" part, if the twisting continues to apply a pressing force downward, the ball head can be locked.

[0042] The inside of the split nut is a threaded hole that can be matched with the thread of the support screw rod, and the outside is hexagonal, which is convenient for twisting with conventional tools. A thread locking groove 2.2.1 is set in the middle position of the split nut along the axial direction, and two threaded holes 2.2.2 are set on one side of the thread locking groove, which are nut locking holes, and screw through holes corresponding to the two nut locking holes are set on the other side of the thread locking groove. When the screws are installed in the nut locking holes and the corresponding screw through holes, the two sides of the thread locking groove are compressed and deformed to achieve the locking effect. At this time, the hexagonal shape on the outside of the split nut can be used with a wrench to twist the support screw rod, so that the support screw rod can be extended and retracted along the center support. At the same time, a double locking effect is produced at the ball head.

[0043] Including airbag bracket 2.3 and clamping slide 2.6

[0044] Figure 6 This is a schematic diagram of the airbag bracket and the clamping slider, with the airbag bracket on the right and the clamping slider on the left. Figure 7 It is an opening and closing connector.

[0045] The airbag bracket is an L-shaped bracket as a whole, consisting of a bottom plate and a side plate. The side plate is fan-shaped, and the upper half of the inner side of the side plate is the airbag contact surface 2.3.1. The airbag contact surface adopts an outward inclined surface to achieve tangential contact with the airbag surface. A threaded hole 2.3.2 is set in the middle of the lower half of the side plate, and the threaded hole is a right-handed threaded hole. Three guide columns 2.4 are vertically fixed on the inner side of the lower half of the side plate and located outside the threaded hole to provide guidance for the movement of the clamping slider and also to limit the freedom of the slider. A ball head 2.5 is vertically fixed in the middle of the outer side of the bottom plate, and the ball head cooperates with the spherical socket of the bracket screw.

[0046] The overall shape of the clamping slider is consistent with the shape of the side plate of the airbag bracket. The upper half of the inner side surface of the clamping slider is the airbag contact surface. The airbag contact surface adopts an outwardly facing inclined surface to achieve tangential contact with the airbag surface. The airbag contact surface on the clamping slider is symmetrically arranged with the airbag contact surface on the airbag bracket. A threaded hole 2.6.1 is arranged in the middle of the lower half of the clamping slider, and the threaded hole is a left-handed threaded hole. Three guide holes 2.6.2 are vertically arranged on the inner side of the lower half of the clamping slider and the periphery of the threaded hole. The three guide holes cooperate with the above-mentioned three guide columns one by one to achieve guide limiting.

[0047] The threaded holes on the above-mentioned airbag bracket and the threaded holes on the clamping slide are set in reverse, and can cooperate with the stud-bolt opening and closing connector 2.7 to achieve relative movement adjustment between the airbag bracket and the clamping slide, so as to adjust the width of the supported airbag, thereby meeting the purpose of supporting thin-walled cylindrical parts with different axial sizes.

[0048] The two ends of the screw rod that can cooperate with the stud-bolt type opening and closing connector are left and right rotating threads, which are connected to the locking slider and the airbag bracket. When rotated, the two are caused to move relative to each other. The bolt head is a hexagon 2.7.1 design, which is easy to rotate with a wrench.

[0049] Inflatable airbag 3

[0050] Figure 8 This is a schematic diagram of an inflatable airbag, which is an inflatable annular airbag made of rubber material. Airbags of different specifications can be replaced according to parts with different diameters. When in use, it can be inflated through the inflation port. After the above-mentioned device is installed and matched, it is placed in the middle of the airbag. After squeezing it through the airbag bracket assembly, the internal air pressure is increased, and it adheres to the inner hole of the part to play a vibration reduction role.

[0051] The method of using the vibration reduction support device of the present invention is as follows:

[0052] (1) Screw the inner ends of the four bracket screws into the four threaded through holes on the central bracket respectively, adjust the extension length of the bracket screws according to the diameter of the parts to keep the extension length consistent. After the adjustment is completed, tighten the thread locking groove on the central bracket with screws to fix the bracket screws;

[0053] (2) Screw the split nut into the bracket screw to the middle position (the specific position is not fixed and does not affect subsequent operations), and at the same time, press the inner end ball heads of the four airbag brackets into the spherical sockets at the outer ends of the four bracket screws one by one; adjust the direction of the ball heads, screw the split nut outward, lock the ball heads with the split nut, and then use a screw to tighten the thread locking groove on the split nut to prevent the split nut from falling off;

[0054] (3) Place the airbag inside the side plate of the airbag bracket (i.e., the open end of the airbag bracket), screw the stud bolt into the right-hand threaded hole of the airbag bracket, fit the clamping slider through the guide hole and the guide column of the airbag bracket, screw the stud bolt into the left-hand threaded hole of the clamping slider, and rotate the stud bolt according to the width of the processed part to adjust the width of the airbag bracket;

[0055] (4) After assembly is completed (such as Figure 1 and 2 As shown in the figure, the device is installed as a whole inside the part, and the airbag is inflated through the airbag inflation port, so that the inner two sides of the airbag are in contact with the airbag contact surface on the airbag bracket and the airbag contact surface on the pressing slider respectively, and the outer surface of the airbag is close to the inner wall of the part to achieve a vibration reduction effect. At the same time, the stud bolt can be fine-tuned to squeeze the airbag to control the airbag support force;

[0056] (5) The parts with the vibration reduction support device installed are clamped on the machine tool for turning. During the machining process, the airbag applies elastic support force to the parts, which has a better vibration reduction effect.

[0057] (6) After the parts are processed, the airbag can be deflated and the device can be taken out.

[0058] Repeat the process to install the mechanism and inflate it again. After replacing the airbag or adjusting the extension length of the bracket screw, unscrew the two screws at the center bracket boss, adjust the position, and then tighten the screws; if you need to adjust the direction of the airbag or adapt to the contour of the part, loosen the opening and closing nut, and then rotate the airbag bracket connected with the ball head to change the direction of the airbag. After adjustment, tighten the opening and closing nut.

[0059] The invention can be used for vibration reduction support of thin-walled parts in industries such as aerospace, aviation, shipbuilding, and precision instruments, and has a very broad prospect for promotion and application in the field of complex large and small batch product processing.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
