[0002] In the prior art, after the palm-shaped bionic mold is welded, there are usually weld scars inside and outside the welding points of its two main components (i.e., the welding points of the arm-shaped embryo and the palm-shaped embryo). In order to improve the product quality of the palm-shaped bionic mold, it is necessary to use a grinding device to grind the inner and outer surfaces of the welding point. However, since the palm-shaped bionic mold is a special-shaped part, and the distance from the welding point to the axial ends of the palm-shaped bionic mold is relatively far, it is difficult for the existing grinding device to effectively grind the weld scars on the inner circumferential wall of the welding point.

[0039] See also Figure 1 and Figure 2An embodiment of the present application provides an internal scar weld removal device 10. The palm-shaped bionic mold includes a welded arm-shaped embryo and a palm-shaped embryo. The internal scar weld removal device 10 is used to grind the inner circumferential wall of the welding point between the arm-shaped embryo and the palm-shaped embryo. The internal scar weld removal device 10 includes a frame 100, a mold 200 and a scar removal unit 300. The mold 200 includes a first mold 210 and a second mold 220.

By driving the linear drive 310 and the rotary drive 320 together, the milling cutter 330 can reach the welding point of the fixed palm-shaped bionic mold through the opening of the arm-shaped embryo and grind the inner wall of the welding point to remove the weld scar there, thereby preparing a high-quality palm-shaped bionic mold.

[0041] It should be noted that the specific connection relationship between the linear drive member 310, the rotary drive member 320 and the milling cutter 330 is not limited, as long as the three are assembled so that the milling cutter 330 can reach the welding position of the fixed palm-shaped bionic mold through the opening of the arm-shaped embryo and grind the inner circumferential wall of the welding position. For example, the milling cutter 330 can be connected to the power output end of the rotary drive member 320, and the rotary drive member 320 can be connected to the power output end of the linear drive member 310. This connection relationship is used as an example in the embodiments of the present application. For details, please refer to Figure 1 .

[0042] It should be noted that the forms of the rotary drive member 320 and the linear drive member 310 are not limited and can be configured according to conventional selections in the art, for example, both are motors.

[0043] It should be noted that the form of the frame 100 is not limited and can be adaptively adjusted according to actual installation requirements.

[0044] See also Figure 1 As an example, the frame 100 includes a base 110 and a vertically arranged first bracket 120, the lower end of the first bracket 120 is fixed to the base 110; the mold 200 and the scar removal unit 300 are respectively located on both sides of the first bracket 120, the first mold 210 is fixed to the first bracket 120, the second mold 220 is arranged on the first bracket 120, and the second mold 220 can be close to or the first mold 210; a through hole corresponding to the fixed channel 250 is arranged on the first bracket 120, and the milling cutter 330 is configured to be able to pass through the channel into the palm-shaped bionic mold.

[0045] In this embodiment, the frame 100 includes a base 110 and a first bracket 120 vertically arranged on the base 110, and the mold 200 and the scar removal unit 300 are respectively located on both sides of the first bracket 120. Specifically, the first mold 210 is fixed to the first bracket 120, and the second mold 220 is arranged on the first bracket 120 and can be close to or away from the first mold 210. In addition, a through hole corresponding to the fixed channel 250 is opened on the first bracket 120, and the milling cutter 330 is configured to be able to pass through the channel into the palm-shaped bionic mold. This setting has the advantages of a more reasonable structural layout and easy operation.

[0046] See also Figure 2 and Figure 3 As an example, the milling cutter 330 includes a connected tool handle 331 and a tool head 332, the tool head 332 is fixed to one end of the tool handle 331, and the other end of the tool handle 331 is connected to the power output end of the rotating drive member 320. The scar removal unit 300 also includes a contoured inner support shaft 340, the tool handle 331 is rotatably accommodated in the contoured inner support shaft 340, and the outer peripheral wall of a section of the contoured inner support shaft 340 close to the tool head 332 is used to fit with the inner peripheral wall of the arm-shaped embryo, and the contoured inner support shaft 340 is connected to the power output end of the linear drive member 310 so that the contoured inner support shaft 340 and the tool handle 331 move synchronously under the drive of the linear drive member 310.

[0047] It should be noted that in the milling cutter 330, the shank 331 and the cutter head 332 can be in the form of an integral connection or in the form of a split and detachable connection. The embodiment of the present application takes the split and detachable form as an example, which has the advantage of being easy to replace and repair.

[0048] In this embodiment, the scar removal unit 300 is further provided with a contoured inner support shaft 340. Specifically, the handle 331 of the milling cutter 330 can be rotatably accommodated in the contoured inner support shaft 340, and the outer circumferential wall of a section of the contoured inner support shaft 340 close to the cutter head 332 is used to fit with the inner circumferential wall of the arm-shaped embryo. By providing the contoured inner support shaft 340 that fits with the inner circumferential wall of the arm-shaped embryo, the milling cutter 330 can be rotated regularly and smoothly along the inner circumferential wall of the arm-shaped embryo during grinding, thereby improving the grinding accuracy, so that the inner and outer walls of the palm-shaped bionic mold at the welding point after grinding have better concentricity, thereby making the overall wall thickness of the palm-shaped bionic mold more uniform.

[0049] It should be noted that since the tool handle 331 can be rotatably accommodated in the contoured inner support shaft 340, there is a certain gap between the outer circumferential wall of the tool handle 331 and the inner circumferential wall of the contoured inner support shaft 340, which may cause the milling cutter 330 to swing during rotation, thereby affecting the grinding accuracy. Based on this, the structure of the contoured inner support shaft 340 can be optimized.

[0050] See also Figure 3 As an example, the inner circumferential walls at both axial ends of the contoured inner support shaft 340 are also installed with annular limit members 341, the inner circumferential wall of the annular limit member 341 is in contact with the outer circumferential wall of the corresponding area of ​​the shank 331, and the annular limit member 341 is an annular copper sleeve or a bearing.

[0051] In this embodiment, annular limit members 341 are additionally provided on the inner circumferential walls at both axial ends of the contoured inner support shaft 340. Specifically, the inner circumferential wall of the annular limit member 341 fits with the outer circumferential wall of the corresponding area of ​​the tool handle 331, so that the tool handle 331 is more stable during rotation, reducing the chance of its shaking, thereby improving the grinding accuracy; in addition, the annular limit member 341 is set to the form of an annular copper sleeve (copper is soft and not easy to cause damage to the milling cutter 330 during rotation) or a bearing (a method commonly used in the field for connecting the fixed part and the rotating part), which has the advantage of not easily causing wear to the tool handle 331, thereby extending the service life of the milling cutter 330.

[0052] It should be noted that the connection method between the annular limiter 341 and the contoured inner support shaft 340 is not limited and can be set according to conventional options in the field. In order to better understand the technical solution, the installation method of the annular copper sleeve is combined here for auxiliary explanation.

Fixing the contoured internal support shaft 340 in this way has the advantages of simple structure and high stability.

[0056] It should be noted that there is no limitation on the closing direction of the mold 200, as long as the outer peripheral wall of the palm-shaped bionic mold can be fixed after closing the mold. For example, the mold can be closed in a vertical direction, or in a horizontal direction, or at other angles, which can be adjusted according to actual needs.
