[0024] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0025] See Figures 1 to 2 , this embodiment provides a lathe roller burnishing tool:

[0026] like Figure 1 As shown, a lathe rolling burnishing tool includes a tool holder 1, a bearing 3 and a rolling burnishing ball 4.

[0027] The knife handle 1 has a first end portion, and is provided with a first accommodating space and a second accommodating space that are interconnected. The shape of the knife handle 1 can be a single shape structure, such as a rectangular parallelepiped structure, or a combination structure composed of multiple shapes, such as a rectangular parallelepiped structure, an arc structure, etc. The shape structure of the knife handle 1 is determined according to its specific application environment. For example, Figure 1 The handle 1 is composed of a combination of various shapes such as a rectangular parallelepiped, an arc-shaped structure, and a quadrangular pyramid. The part of the handle 1 close to its first end is a quadrangular pyramid structure. The quadrangular pyramid structure reduces the area of the first end, which is beneficial to the contact between the rolling ball and the part.

[0028] The bearing 3 is installed in the first accommodation space, and the polishing ball 4 is installed in the second accommodation space. The polishing ball 4 protrudes from the first end of the tool handle 1. The circumferential surface of the outer ring of the bearing 3 contacts the polishing ball 4. When the part is polished, the polishing ball 4 contacts the part. When the part rotates, the polishing ball 4 rotates. When the polishing ball 4 rotates, the bearing 3 rotates. Figure 2 As shown, the circumferential surface of the outer ring of the bearing 3 contacts the polished ball 4, and the rotation direction of the bearing 3 is facing the polished ball 4, so that the polished ball 4 can rotate when processing parts.

[0029] Generally, the polishing ball 4 is a steel ball, so that parts made of materials such as titanium alloy can be processed.

[0030] In some embodiments, the side of the handle 1 is provided with a first mounting hole, and the first mounting hole constitutes a first accommodation space. The first mounting hole can be a through hole or a blind hole, and the first mounting hole can be a round hole or a square hole, for example, Figure 1 The first mounting hole is a through hole that passes through two opposite sides of the handle 1.

[0031] The bearing 3 is installed in the first mounting hole via the rotating shaft 6. For example, two opposite first limiting holes 2 are provided on the side wall of the first mounting hole. The two first limiting holes 2 are coaxial. The bearing 3 is installed on the rotating shaft 6, and the two ends of the rotating shaft 6 are respectively installed in the two first limiting holes 2.

[0032] In some embodiments, the handle 1 is provided with a first limiting structure for limiting the axial movement of the rotating shaft 6. Figure 1 As shown, a first threaded hole is provided on the side of the first limiting hole 2 on the handle 1, and a bolt ( Figure 1(not shown in the figure), the head of the bolt is located outside the end of the rotating shaft 6, and the orthographic projection of the head of the bolt on the plane to which the end of the rotating shaft 6 belongs overlaps with the end of the rotating shaft 6. By rotating the bolt, the head of the bolt contacts the end of the rotating shaft 6, thereby limiting the rotating shaft 6 and preventing the rotating shaft 6 from moving along its axial direction.

[0033] The number of the first threaded holes on the same side is one or more. Generally, only one threaded hole and bolt are required on each side to limit the rotation shaft 6, and the remaining threaded holes and bolts can be used as backup.

[0034] In some embodiments, the first end of the handle 1 is provided with a second mounting hole, the second mounting hole connecting the first end of the handle 1 and the first accommodation space, and the second mounting hole forming the second accommodation space. The second mounting hole adopts a structure that facilitates the rolling of the polished ball 4, for example, Figure 1 The second mounting hole is a round hole, and the polishing ball 4 is located in the second mounting hole.

[0035] In some embodiments, the knife handle 1 is provided with a second limiting structure for limiting the rolling ball 4 from moving out of the second accommodation space along the direction of the first end.

[0036] For example, the lathe rolling tool also includes a limiting shaft 7, two second limiting holes 5 are set on the tool handle 1, and the second limiting holes 5 are connected to the second mounting hole. A limiting shaft 7 is installed in each second limiting hole 5, and the distance between the two limiting shafts 7 is smaller than the diameter of the rolling ball 4. The limiting shaft 7 is located on the side of the rolling ball 4 close to the first end of the tool handle 1.

[0037] like Figure 1 As shown, two second limiting holes 5 are provided on two opposite side surfaces of the knife handle 1 near the first end, and the middle part of the second limiting hole 5 is connected to the second mounting hole. A limiting shaft 7 is installed in each second limiting hole 5, and the limiting shaft 7 passes through the second mounting hole. The distance between the two limiting shafts 7 is smaller than the diameter of the rolling ball 4. The limiting shaft 7 is located on the side of the rolling ball 4 near the first end, thereby preventing the rolling ball 4 from moving out of the second accommodating space along the direction of the first end of the knife handle 1.

[0038] Because one side of the polishing ball 4 contacts the bearing 3, a limiting shaft 7 is provided on the other side of the polishing ball 4, effectively confining the polishing ball 4 within the second accommodation space. To remove the polishing ball 4, the limiting shaft 7 can be removed first, and then the polishing ball 4 can be removed from the first end of the tool handle 1, making it easy to replace the polishing ball 4.

[0039] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
