[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-2This utility model provides a technical solution: a conical surface rolling device with an automatically adjustable tilt angle, including a cutter head 3, a cutter body 6 and a cutter shank 12. The cutter shank 12 is a general-purpose lathe cutter shank for clamping and use. The feed side of the cutter head 3 is connected to a rolling head 2, and the front end of the rolling head 2 is provided with multiple rollers 1 extending out of its exterior. The multiple rollers 1 are evenly distributed in a ring at 90-degree intervals on the outside of the rolling head 2.

[0024] The blade head 3 is installed at the end of the blade body 6, and the end of the blade body 6 is rotatably installed on the handle 12 via the pivot point 4. The handle 12 is equipped with a track 11, and a slider 10 is slidably installed on the track 11. The slider 10 is installed on the blade body 6.

[0025] The blade 6 is provided with a pressure adjustment mechanism, which includes a base plate 5 connected to the blade head 3. One end of a spring 7 is installed on the side of the base plate 5 away from the blade head 3, and the other end of the spring 7 is connected to a top plate 8. An adjustment knob 9 is provided on one side of the top plate 8.

[0026] Refer to the instruction manual. Figure 2 As can be seen, in this utility model, the track 11 is an arc track, the slider 10 is a circular block, the slider 10 can slide freely in the track 11, the slider 10 drives the blade 6 to rotate freely, and the blade 6 further drives the blade head 3 to rotate freely.

[0027] In this invention, the pressure adjustment mechanism is located inside the blade body 6, and both the bottom plate 5 and the top plate 8 are slidably installed inside the blade body 6 along the length direction. The blade head 3 is slidably installed at the end of the blade body 6. The adjustment knob 9 is rotatably installed on the blade body 6. An extension plate is fixedly installed on the side of the top plate 8 away from the bottom plate 5, and the extension plate is located below the adjustment knob 9. The adjustment knob 9 is pressed against the extension plate. By adjusting the position of the top plate 8, and then by rotating the adjustment knob 9 to press the extension plate on the top plate 8, the position of the top plate 8 is fixed. The top plate 8 pulls the bottom plate 5 through the spring 7. Therefore, the bottom plate 5 tightens the blade head 3, thereby achieving the purpose of tightening the blade head 3.

[0028] Furthermore, by loosening the adjustment knob 9, the base plate 5 and top plate 8 move due to the force of the spring 7, so that the cutter head 3 is no longer pulled, thus achieving the purpose of loosening the cutter head 3.

[0029] In this utility model, the blade 6 is a frame structure, and one end of the blade head 3 extends into the blade 6. The frame structure of the blade 6 facilitates the installation and tightening of the blade head 3 and facilitates the operation of the top plate 8.

[0030] In this utility model, sliding grooves are provided on both sides of the inner wall of the blade 6, and the bottom plate 5 and the top plate 8 are slidably installed in the sliding grooves. The sliding grooves facilitate the movement of the bottom plate 5 and the top plate 8 of the pressure adjustment mechanism, making it easy to tighten and loosen.

[0031] In this utility model, the cutter head 3 is provided with a mounting hole, and the cutter head 3 is sleeved on the rotating fulcrum 4 through the mounting hole. The mounting hole facilitates the direct locking of the cutter head 3 onto the rotating fulcrum 4, making it easy to quickly install the cutter head 3.

[0032] This utility model is as follows Figure 2 As shown, when the roller 1 is used to process a conical surface, the characteristics of this tool are: when the conical surface is parallel to the axis of the roller 1, the tool is in a balanced state, and the roller 1 uniformly presses the processed surface to achieve surface strengthening; if the conical surface is not parallel to the axis of the roller 1, a deflection force will be generated in the structure of the slider 10 and the track 11. The deflection force drives the slider 10 to move in the track 11 until a new equilibrium state is reached, thereby satisfying the rolling processing of conical surfaces with different tapers.
