Description

Technical Field

[0001] This application relates to the field of palm-shaped bionic mold manufacturing technology, and more specifically, to an internal scar weld removal device. Background Technology

[0002] In the prior art, after the palm-shaped bionic mold is welded, weld scars usually exist on the inside and outside of the weld joints of its two main components (i.e., the weld joints of the arm-shaped preform and the palm-shaped preform). 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 weld joint. However, since the palm-shaped bionic mold is an irregularly shaped part, and the distance from the weld joint to the two ends of the palm-shaped bionic mold along the axis is relatively far, the existing grinding device is difficult to effectively grind the weld scars on the inner peripheral wall of the weld joint. Utility Model Content

[0003] The purpose of this application is to provide an internal weld scar removal device that can effectively grind the weld scars on the inner peripheral wall of the weld joint of a palm-shaped bionic mold.

[0004] The embodiments of this application are implemented as follows:

[0005] This application provides an internal weld scar removal device. The palm-shaped bionic mold includes welded arm-shaped preforms and palm-shaped preforms. The internal weld scar removal device is used to grind the inner peripheral wall of the weld joint between the arm-shaped preforms and the palm-shaped preforms. The device includes a frame, a mold, and a scar removal unit. The mold includes a first mold and a second mold. The first mold is fixed to the frame, and the second mold can approach the first mold and close with it to form a fixed channel for matching the outer peripheral wall of the palm-shaped bionic mold. The scar removal unit includes a drive assembly and a milling cutter. The drive assembly is disposed on the frame and includes a linear drive and a rotary drive. The linear drive drives the connected milling cutter so that the milling cutter extends from the opening of the arm-shaped preform into the weld joint of the fixed palm-shaped bionic mold. The rotary drive drives the connected milling cutter so that the milling cutter rotates to grind the inner peripheral wall of the weld joint.

[0006] In the above technical solution, the internal weld scar removal device includes a frame, a mold, and a scar removal unit. Specifically, the mold includes a first mold and a second mold. After the first mold and the second mold are closed, they form a fixed channel for matching the outer peripheral wall of the palm-shaped bionic mold, so as to fix the palm-shaped bionic mold during grinding. The scar removal unit includes a drive assembly and a milling cutter. The drive assembly includes a linear drive and a rotary drive. The linear drive drives the connected milling cutter so that the milling cutter extends from the opening of the arm-shaped preform into the weld joint of the fixed palm-shaped bionic mold. The rotary drive drives the connected milling cutter so that the milling cutter rotates to grind the inner peripheral wall of the weld joint. Through the combined drive of the linear drive and the rotary drive, the milling cutter can reach the weld joint of the fixed palm-shaped bionic mold through the opening of the arm-shaped preform and grind the inner peripheral wall of the weld joint to remove the weld scar, thereby producing a high-quality palm-shaped bionic mold.

[0007] In some alternative implementations, the frame includes a base and a vertically arranged first support, the lower end of which is fixed to the base; the mold and the scar removal unit are located on opposite sides of the first support, the first mold is fixed to the first support, the second mold is disposed on the first support, and the second mold can approach or be adjacent to the first mold; the first support is provided with a through hole corresponding to the fixed channel, and the milling cutter is configured to pass through the channel and enter the palm-shaped bionic mold.

[0008] In the above technical solution, the frame includes a base and a first support vertically arranged on the base. The mold and the scar removal unit are located on both sides of the first support. Specifically, the first mold is fixed to the first support, and the second mold is arranged on the first support and can be close to or adjacent to the first mold. Furthermore, a through hole corresponding to the fixed channel is opened on the first support, and the milling cutter is configured to pass through the channel and enter the palm-shaped bionic mold. This arrangement has the advantages of a more reasonable structural layout and ease of operation.

[0009] In some alternative embodiments, the inner peripheral wall of the fixed channel near the through hole is recessed outward and provided with a notch extending to the end face, the peripheral wall of the notch being used to fix the thickened portion of the outer peripheral wall of the arm-shaped embryo.

[0010] In the above technical solution, for the thickened part of the outer peripheral wall of the arm-shaped preform, a notch for fixing the thickened part of the outer peripheral wall is provided at the corresponding position of the fixing channel. This can improve the fixing stability of the entire palm-shaped bionic mold during grinding, so that the milling cutter is always at the inner peripheral wall of the weld, thereby improving the grinding accuracy.

[0011] In some alternative embodiments, the milling cutter includes a connected shank and a cutter head, the cutter head being fixed to one end of the shank and the other end of the shank being connected to the power output of a rotary drive. The scar removal unit also includes a contoured inner support shaft, in which the shank is rotatably housed. The outer peripheral wall of the contoured inner support shaft near the cutter head is used to fit against the inner peripheral wall of the arm-shaped preform. The contoured inner support shaft is connected to the power output of a linear drive so that the contoured inner support shaft and the shank move synchronously under the drive of the linear drive.

[0012] In the above technical solution, the scar removal unit is further provided with a contoured inner support shaft. Specifically, the shank of the milling cutter is rotatably housed in the contoured inner support shaft, and the outer peripheral wall of the section of the contoured inner support shaft near the cutter head is used to fit against the inner peripheral wall of the arm-shaped preform. By setting the contoured inner support shaft that fits against the inner peripheral wall of the arm-shaped preform, the milling cutter can rotate regularly and smoothly along the inner peripheral wall of the arm-shaped preform during grinding, thereby improving the grinding accuracy. This ensures that the inner and outer walls of the palm-shaped bionic mold after grinding have better concentricity at the welding point, and thus makes the overall wall thickness of the palm-shaped bionic mold more uniform.

[0013] In some alternative embodiments, the internal scar removal device further includes a second bracket, a linear drive fixed to the base, and the power output end of the linear drive connected to the second bracket. The second bracket has a mounting hole corresponding to the through hole, and the end of the contoured inner support shaft away from the cutter head is fixed in the mounting hole so that the contoured inner support shaft and the cutter shank move synchronously under the drive of the linear drive.

[0014] In the above technical solution, the linear drive is fixed to the base, and the internal scar removal device is equipped with a second bracket to fix the contouring inner support shaft. Specifically, the second bracket is connected to the power output end of the linear drive, and the second bracket has a mounting hole corresponding to the through hole. The end of the contouring inner support shaft away from the cutter head is fixed in the mounting hole. Fixing the contouring inner support shaft in this way has the advantages of simple structure and high stability.

[0015] In some alternative implementations, annular limiting members are also installed on the inner peripheral walls of both axial ends of the contoured inner support shaft. The inner peripheral wall of the annular limiting member fits against the outer peripheral wall of the corresponding area of ​​the tool holder, and the annular limiting member is an annular copper sleeve or a bearing.

[0016] In the above technical solution, annular limiting components are added to the inner peripheral walls at both ends of the axial direction of the contoured inner support shaft. Specifically, the inner peripheral wall of the annular limiting component fits against the outer peripheral wall of the corresponding area of ​​the tool holder, so that the tool holder is more stable during rotation, reducing the probability of wobbling and thus improving grinding accuracy. In addition, setting the annular limiting component as an annular copper sleeve or bearing has the advantage of not easily causing wear on the tool holder, thereby extending the service life of the milling cutter.

[0017] In some alternative embodiments, the internal weld scar removal device further includes a third support, on which a rotary drive is mounted. The third support and the second support are spaced apart along the movement path of the milling cutter, and both the second and third supports are connected to a support plate, which is connected to the power output shaft of the linear drive.

[0018] In the above technical solution, the internal scar weld removal device is equipped with a third bracket for mounting the rotary drive component. Specifically, the third bracket and the second bracket are distributed at intervals along the movement path of the milling cutter, and the second bracket and the third bracket are connected to the power output end of the linear drive component through a support plate. This arrangement facilitates the linear drive component to drive the rotary drive component and the contoured inner support shaft at the same time, and has the advantages of a more reasonable structural design and easy operation.

[0019] In some alternative implementations, the first mold and the second mold are distributed opposite each other in the vertical direction. The first mold is fixedly connected to the frame, and the second mold is connected to the power output end of the vertical drive component so that the second mold can approach the first mold and close with the first mold. The vertical drive component is fixedly connected to the frame through a mounting plate.

[0020] In the above technical solution, the first mold and the second mold are distributed opposite each other in the vertical direction, that is, the molds are closed in the vertical direction. Specifically, the first mold is fixedly connected to the frame, and the second mold can approach the first mold under the drive of the vertical drive component. The vertical drive component is fixedly connected to the frame through the mounting plate. This configuration has the advantages of high mold closing accuracy and high structural stability.

[0021] In some alternative implementations, the first mold is located below the second mold, and the internal weld scar removal device further includes a vertically arranged support member, the bottom end of which is fixed to the frame, and the top of which abuts against the bottom of the first mold.

[0022] In the above technical solution, the first mold is set below the second mold, and the inner scar weld removal device is equipped with a support member for supporting the first mold, which helps to improve the fixing stability of the first mold, thereby improving the fixing stability of the mold on the palm-shaped bionic mold.

[0023] In some alternative implementations, the internal scar removal device also includes a control system, with the drive assembly and vertical drive component all electrically connected to the control system.

[0024] In the above technical solution, the internal weld scar removal device is equipped with a control system, and the drive components and vertical drive components are electrically connected to the control system so that the operating status of each drive component can be centrally controlled, thereby improving the automation level of the internal weld scar removal device and thus improving the controllability of the internal weld scar removal device.

[0038] The following is a detailed description of an internal weld scar removal device according to this application.

[0039] See Figure 1 and Figure 2This application provides an internal scar weld removal device 10. The palm-shaped bionic mold includes a welded arm-shaped preform and a palm-shaped preform. The internal scar weld removal device 10 is used to grind the inner peripheral wall of the weld joint of the arm-shaped preform and the palm-shaped preform. 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. The first mold 210 is fixed to the frame 100, and the second mold 220 can approach the first mold 210 and close with it to form a fixed channel 250 for matching the outer peripheral wall of the palm-shaped bionic mold. The scar removal unit 300 includes a drive assembly and a milling cutter 330. The drive assembly is disposed on the frame 100 and includes a linear drive member 310 and a rotary drive member 320. The linear drive member 310 drives the connected milling cutter 330 so that the milling cutter 330 extends from the opening of the arm-shaped preform into the weld joint of the fixed palm-shaped bionic mold. The rotary drive member 320 drives the connected milling cutter 330 so that the milling cutter 330 rotates to grind the inner peripheral wall of the weld joint so as to remove excess material by grinding.

[0040] In this application, the internal weld scar removal device 10 includes a frame 100, a mold 200, and a scar removal unit 300. Specifically, the mold 200 includes a first mold 210 and a second mold 220. After the first mold 210 and the second mold 220 are closed, a fixed channel 250 is formed for matching the outer peripheral wall of the palm-shaped bionic mold, so as to fix the palm-shaped bionic mold during grinding. The scar removal unit 300 includes a drive assembly and a milling cutter 330. The drive assembly includes a linear drive member 310 and a rotary drive member 320. The linear drive member 310 drives the connected milling cutter 330 so that the milling cutter 330 extends from the opening of the arm-shaped preform into the weld joint of the fixed palm-shaped bionic mold. The rotary drive member 320 drives the connected milling cutter 330 so that the milling cutter 330 rotates to grind the inner peripheral wall of the weld joint. Driven by the combined linear drive 310 and rotary drive 320, the milling cutter 330 can reach the welding point of the fixed palm-shaped bionic mold through the opening of the arm-shaped preform and grind the inner peripheral wall of the welding point to remove the weld scar, thereby producing a high-quality palm-shaped bionic mold.

[0041] It should be noted that the specific connection relationship between the linear drive 310, the rotary drive 320, and the milling cutter 330 is not limited, as long as the assembly of the three components allows the milling cutter 330 to reach the welding point of the fixed palm-shaped bionic mold through the opening of the arm-shaped preform and to grind the inner peripheral wall of the welding point. For example, the milling cutter 330 can be connected to the power output end of the rotary drive 320, and the rotary drive 320 can be connected to the power output end of the linear drive 310. This connection relationship is used as an example in the embodiments of this application. For details, please refer to the relevant documentation. Figure 1 .

[0042] It should be noted that the rotary drive 320 and the linear drive 310 are not limited in form and can be configured in accordance with conventional choices in the art, such as both being motors.

[0043] It should be noted that the form of the frame 100 is not limited and can be adapted to meet actual installation needs.

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

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

[0046] See Figure 2 and Figure 3 As an example, the milling cutter 330 includes a connected shank 331 and a cutter head 332. The cutter head 332 is fixed to one end of the shank 331, and the other end of the shank 331 is connected to the power output end of the rotary drive 320. The scar removal unit 300 also includes a contouring inner support shaft 340. The shank 331 is rotatably housed in the contouring inner support shaft 340, and the outer peripheral wall of the contouring inner support shaft 340 near the cutter head 332 is used to fit against the inner peripheral wall of the arm-shaped preform. The contouring inner support shaft 340 is connected to the power output end of the linear drive 310 so that the contouring inner support shaft 340 and the shank 331 move synchronously under the drive of the linear drive 310.

[0047] It should be noted that in the milling cutter 330, the shank 331 and the cutter head 332 can be connected as an integral unit or as separate detachable units. In this embodiment, the separate detachable unit is used as an example, which has the advantage of being easy to replace and maintain.

[0048] In this embodiment, the scar removal unit 300 is further provided with a contoured inner support shaft 340. Specifically, the shank 331 of the milling cutter 330 is rotatably accommodated in the contoured inner support shaft 340. The outer peripheral wall of the contoured inner support shaft 340 near the cutter head 332 is used to fit against the inner peripheral wall of the arm-shaped preform. By providing the contoured inner support shaft 340 that fits against the inner peripheral wall of the arm-shaped preform, the milling cutter 330 can rotate regularly and smoothly along the inner peripheral wall of the arm-shaped preform during grinding, thereby improving the grinding accuracy. This results in better concentricity of the inner and outer walls of the palm-shaped bionic mold at the welding point after grinding, and thus makes the overall wall thickness of the palm-shaped bionic mold more uniform.

[0049] It should be noted that since the tool holder 331 is rotatably housed within the contouring inner support shaft 340, there is a certain gap between the outer peripheral wall of the tool holder 331 and the inner peripheral wall of the contouring inner support shaft 340. This may cause the milling cutter 330 to wobble during rotation, thereby affecting the grinding accuracy. Based on this, the structure of the contouring inner support shaft 340 can be optimized.

[0050] See Figure 3 As an example, the inner peripheral walls at both ends of the contoured inner support shaft 340 are also equipped with annular limiting members 341. The inner peripheral wall of the annular limiting member 341 fits against the outer peripheral wall of the corresponding area of ​​the tool holder 331, and the annular limiting member 341 is an annular copper sleeve or a bearing.

[0051] In this embodiment, annular limiting members 341 are added to the inner peripheral walls of both axial ends of the contoured inner support shaft 340. Specifically, the inner peripheral wall of the annular limiting member 341 fits against the outer peripheral wall of the corresponding area of ​​the tool holder 331, so that the tool holder 331 is more stable during rotation, reducing the probability of its shaking and thus improving the grinding accuracy. In addition, setting the annular limiting member 341 as an annular copper sleeve (copper is soft and not easy to damage during the rotation of the milling cutter 330) or a bearing (a common method in the art for connecting the fixed part and the rotating part) has the advantage of not easily causing wear to the tool holder 331, thereby extending the service life of the milling cutter 330.

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

[0053] As one type, the annular sleeve includes a sleeve body and a connecting part protruding from the sleeve body. The connecting part is located on the side of the sleeve body near the end face and is threadedly connected to the contoured inner support shaft 340.

[0054] See Figure 2 and Figure 4As an example, the internal scar removal device 10 also includes a second bracket 400, a linear drive 310 fixed to the base 110, and the power output end of the linear drive 310 connected to the second bracket 400. The second bracket 400 has a mounting hole 410 corresponding to the through hole. The end of the contoured inner support shaft 340 away from the cutter head 332 is fixed in the mounting hole 410 so that the contoured inner support shaft 340 and the cutter shank 331 move synchronously under the drive of the linear drive 310.

[0055] In this embodiment, the linear drive 310 is fixed to the base 110, and the inner weld removal device 10 is provided with a second bracket 400 to fix the contouring inner support shaft 340. Specifically, the second bracket 400 is connected to the power output end of the linear drive 310, and the second bracket 400 has a mounting hole 410 corresponding to the through hole. The end of the contouring inner support shaft 340 away from the cutter head 332 is fixed in the mounting hole 410. Fixing the contouring inner support shaft 340 in this way has the advantages of simple structure and high stability.

[0056] It should be noted that the mold closing direction of mold 200 is not limited, as long as the outer peripheral wall of the palm-shaped bionic mold can be fixed after mold closing. For example, the mold closing can be in the vertical direction, the horizontal direction, or other angles. The specific direction can be adjusted according to actual needs.

[0057] See Figure 1 and Figure 5 As an example, the first mold 210 and the second mold 220 are distributed opposite each other in the vertical direction. The first mold 210 is fixedly connected to the frame 100, and the second mold 220 is connected to the power output end of the vertical drive member 230 so that the second mold 220 can approach the first mold 210 and close the mold with the first mold 210. The vertical drive member 230 is fixedly connected to the frame 100 through the mounting plate 240.

[0058] In this embodiment, the first mold 210 and the second mold 220 are distributed opposite each other in the vertical direction, that is, the mold 200 is closed in the vertical direction. Specifically, the first mold 210 is fixedly connected to the frame 100, and the second mold 220 can approach the first mold 210 under the drive of the vertical drive member 230. The vertical drive member 230 is fixedly connected to the frame 100 through the mounting plate 240. This arrangement has the advantages of high mold closing accuracy and high structural stability.

[0059] It should be noted that the form of the vertical drive component 230 is not limited; for example, it can be a motor, a cylinder, or a hydraulic cylinder.

[0060] See Figure 1 and Figure 5As an example, the first mold 210 is located below the second mold 220. The internal weld scar removal device 10 also includes a vertically arranged support member 700. The bottom end of the support member 700 is fixed to the frame 100, and the top of the support member 700 abuts against the bottom of the first mold 210.

[0061] In this embodiment, the first mold 210 is positioned below the second mold 220, and the inner scar removal device 10 is equipped with a support member 700 for supporting the first mold 210, which helps to improve the fixing stability of the first mold 210, thereby improving the fixing stability of the mold 200 on the palm-shaped bionic mold.

[0062] See Figure 5 As an example, the inner peripheral wall of the fixed channel 250 near the through hole is recessed outward and has a notch 251 extending to the end face. The peripheral wall of the notch 251 is used to fix the thickened portion of the outer peripheral wall of the arm-shaped embryo.

[0063] In this embodiment, for the thickened portion of the outer peripheral wall of the arm-shaped preform, a notch 251 for fixing the outer peripheral wall of the thickened portion is provided at the corresponding position of the fixing channel 250. This can improve the fixing stability of the entire palm-shaped bionic mold during grinding, so that the milling cutter 330 is always at the inner peripheral wall of the weld, thereby improving the grinding accuracy.

[0064] See Figure 1 As an example, the internal scar removal device 10 also includes a third bracket 500, a rotary drive 320 mounted on the third bracket 500, the third bracket 500 and the second bracket 400 being distributed at intervals along the movement path of the milling cutter 330, and both the second bracket 400 and the third bracket 500 being connected to a support plate 600, the support plate 600 being connected to the power output shaft of the linear drive 310.

[0065] In this embodiment, the internal scar removal device 10 is equipped with a third bracket 500 for mounting the rotary drive 320. Specifically, the third bracket 500 and the second bracket 400 are distributed at intervals along the movement path of the milling cutter 330, and the second bracket 400 and the third bracket 500 are connected to the power output end of the linear drive 310 through the support plate 600. This arrangement facilitates the linear drive 310 to simultaneously drive the rotary drive 320 and the contoured inner support shaft 340, and has the advantages of a more reasonable structural design and easy operation.

[0066] In other possible implementations, the rotary drive 320 and the contoured inner support shaft 340 may also be connected to the power output end of the linear drive 310, respectively.

[0067] See Figure 6As an example, the internal scar removal device 10 also includes a control system 800, and the drive assembly and the vertical drive 230 are both electrically connected to the control system 800.
