[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0030] Currently, before replacing the threaded sleeve of the rectifier cone's front cone, it is necessary to perform flanging using methods such as hammering with a hammer punch head or manual press with a press head. However, due to the uncontrollable force and lack of pressure holding of the hammering method and manual press, the rectifier cone's front cone shell is easily damaged, and the flanging quality of the threaded sleeve is unstable.

[0031] Therefore, the design concept of this application is to redesign the power feed structure of the stamping head so that the force can be controlled and the pressure can be maintained, thus ensuring the quality of the flanging.

[0032] The M10 bolt is rotated by a digital torque wrench to provide axial feed force. The M10 bolt is then connected to the thrust ball bearing via an adapter. The thrust ball bearing is installed in the countersunk hole of the stamping head, which ultimately enables the stamping head to move downward. This tooling is used to flanging the countersunk hole of the front cone of the rectifier cone. It belongs to the research and development field of accessory maintenance and testing tooling of the aviation department.

[0033] like Figure 1-6 As shown, this application provides a countersunk flange tooling for the front taper thread sleeve of a rectifier cone, which is turned using a digital torque wrench. It includes a vertically placed C-shaped clamp 2, with a bolt 1 threadedly connected to the top of the C-shaped clamp 2. An adapter 3 is connected to the bottom of the bolt 1, and a thrust ball bearing 4 is connected to the adapter 3. A stamping head 5 is connected to the thrust ball bearing 4. The axes of the bolt 1, the adapter 3, the thrust ball bearing 4, and the stamping head 5 are coincident. The bolt 1 is an M10 bolt.

[0034] The top of the C-shaped clamp 2 is provided with a threaded hole 21, which is threadedly connected to the bolt 1. When in use, the bolt 1 is turned and rotated up and down within the threaded hole 21.

[0035] The adapter 3 includes an upper internal threaded sleeve 31 that is threaded to the bottom of the bolt 1, a middle connecting plate 32 that is threaded to the upper internal threaded sleeve 31, and a lower optical shaft 33 that is threaded to the middle connecting plate 32. The lower optical shaft 33 is fixedly connected to the inner ring of the thrust ball bearing 4. When in use, the bolt 1 is turned up and down, and the adapter 3 will turn up and down accordingly.

[0036] The outer ring of the thrust ball bearing 4 is fixedly connected to the stamping head 5. In use, the screw 1 rotates the adapter 3 to move up and down, and the adapter 3 moves the stamping head 5 up and down through the thrust ball bearing 4. The function of the thrust ball bearing 4 is to drive the stamping head 5 to move up and down without rotating with the adapter 3.

[0037] The stamping head 5 includes a top countersunk hole 51 connected to the outer ring of the thrust ball bearing 4, a stamping rod 52 connected to the top countersunk hole 51, and a stamping head body 53 connected to the bottom of the stamping rod 52; the outer ring of the thrust ball bearing 4 is fixedly connected to the top countersunk hole 51.

[0038] The sidewall of the stamping head body 53 adopts a micro-conical surface structure. In fact, the stamping head 5 of this application is an improvement on the existing stamping head. The existing stamping head includes a stamping rod and a stamping head body. When in use, the top of the stamping rod is pressed by a hammer or a manual press, and the stamping head body will move down to apply force to the countersunk head and complete the flanging operation. In this application, a top countersunk hole 51 is added to the top of the stamping rod of the existing stamping head for connecting the outer ring of the thrust ball bearing 4.

[0039] In this application, a digital torque wrench is used to rotate the hexagonal head of the M10 bolt clockwise, causing the M10 bolt to move downward relative to the C-clamp. The adapter connects the M10 bolt and the thrust ball bearing. Due to the action of the thrust ball bearing, the rotation of the M10 bolt itself will not cause the stamping head to rotate. The downward axial force of the M10 bolt pushes the stamping head downward, thereby applying force to the countersunk hole of the threaded sleeve to complete the flanging operation.

[0040] Technical effects of this application (1) Compared with the manual method of using a hammer to strike the stamping head for flanging, this application uses a threaded feed method to provide pressure, which can ensure the constant pressure value during repeated flanging operations, and also avoid the problem of damage to the front cone shell of the rectifier cone caused by excessive force. (2) Compared with the method of using a manual press to press the punch head for flanging, the manual press provides power through a handle or rotating structure. Since the human body cannot maintain one action for a long time, it cannot maintain pressure at a certain constant pressure value for a long time. This application uses the thread feed of M10 bolt and C-clamp to provide power. Through the adapter and thrust ball bearing, the purpose of keeping the punch head axially feed and not rotating is achieved while the M10 bolt rotates radially. After reaching a certain constant value, the pressure value can remain unchanged after the wrench with applied torque is removed.

Unless explicitly required, individual components and functions are optional, and the order of operation may vary.

The scope of this application is limited only by the appended claims.
