Description

Technical Field

[0001] This utility model relates to the field of CNC machining of caps, specifically a CNC machining fixture for caps. Background Technology

[0002] A cap is a part used to cover, close, or connect mechanical components. It is commonly used in sealing, protection, or functional assembly scenarios. When machining caps, CNC machining technology is often used. CNC machining, or computer numerical control machining, is a technology that uses pre-programmed digital instructions to control machine tools for automated precision machining. It covers a variety of processes such as cutting, drilling, and milling. When using CNC machining technology to process caps, machining fixtures are required for auxiliary processing.

[0003] However, current machining fixtures still have some shortcomings. Existing machining fixtures have not fully considered the rotation structure. When using machining fixtures to perform CNC machining on caps, if the machining fixture does not fully consider the rotation structure, the machining area of ​​the workpiece may be limited, making it inconvenient to process different positions of the workpiece later. This may result in incomplete machining of the workpiece and make it inconvenient for operators to use the machining fixture.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model studies and improves the existing structure and its deficiencies, and provides a CNC machining fixture for a cap. Utility Model Content

[0005] The purpose of this invention is to provide a CNC machining fixture for caps to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC machining fixture for a cap, comprising a fixed plate, a rotating assembly, and a lifting rod. A support column is fixedly connected to the bottom of the fixed plate, and a support plate is provided on the inner side of the fixed plate. The rotating assembly is provided on the side of the support plate and includes a fixed frame, a servo motor, a rotating rod, a first gear, and a second gear. The lifting rod is welded to the four sides of the bottom of the support plate, and a lifting plate is welded to the bottom end of the lifting rod. A limit assembly is provided on the inner side of the support plate, and the limit assembly includes a drive motor, a limit screw, a lifting component, a rotating rod, a sliding block, a fixed rod, and a limit block.

[0007] Furthermore, the fixing frame is fixedly connected to the bottom side of the fixing plate, and a servo motor is provided on the inner side of the fixing frame. The output shaft of the servo motor is fixedly connected to a rotating rod through a coupling, and the end of the rotating rod is rotatably connected to the fixing plate.

[0008] Furthermore, a first gear is fixedly connected to the outer wall of the rotating rod, and a second gear is meshed and rotatably connected to one side of the first gear. The second gear is fixedly connected to the outer wall of the support plate, and both the first gear and the second gear are located inside the fixed plate.

[0009] Furthermore, the drive motor is located below the hanging plate, and the output shaft of the drive motor is fixedly connected to a limit screw through a coupling, and the bottom end of the limit screw is rotatably connected to the hanging plate.

[0010] Furthermore, the top end of the limiting screw is rotatably connected to the bottom center of the support plate, and a lifting component is rotatably connected to the outer side of the middle section of the limiting screw via a thread, and rotating rods are rotatably connected to the four sides of the lifting component.

[0011] Furthermore, the other end of the rotating rod is rotatably connected to a sliding block, and a fixed rod is connected through the center of the sliding block, with the end of the fixed rod welded to the inside of the support plate.

[0012] Furthermore, a limiting block is welded to the top of the sliding block, and the limiting block is positioned above the support plate, with a protective pad fixedly attached to the side of the limiting block.

[0013] Furthermore, an extension member is engaged with the upper part of the limiting block, and a capping member is engaged with the upper part of the extension member. Square blocks are welded to the sides of both the extension member and the capping member, and the square blocks are fixedly connected to the limiting block and the extension member respectively by bolts.

[0014] This utility model provides a CNC machining fixture for a cap, which has the following beneficial effects:

[0015] 1. This utility model is equipped with a rotating component. During the CNC machining process of the cap using a machining fixture, the meshing rotation between the first gear and the second gear causes the second gear to rotate along with the first gear, thereby causing the support plate to rotate as well. This achieves the rotation processing of the workpiece, facilitating subsequent processing of different positions on the workpiece. This makes the machining fixture more efficient, has a simple structure, and is easy for operators to use.

[0016] 2. This utility model is equipped with a limiting component. During the CNC machining of the cap using the machining fixture, as the lifting component descends, the sliding block gradually engages and slides inside the support plate. This allows the limiting block welded to the top of the sliding block to limit and clamp the side of the workpiece. The structure is tightly connected, preventing deviation during subsequent workpiece machining and ensuring smooth machining of the cap using the machining fixture. The structure is simple and convenient for operators to use the machining fixture. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figure 1 and Figure 2 As shown, a CNC machining fixture for a cap includes a fixed plate 1, a rotating assembly 4, and a hanging rod 5. A support column 2 is fixedly connected to the bottom of the fixed plate 1, and a support plate 3 is provided on the inner side of the fixed plate 1. The rotating assembly 4 is provided on the side of the support plate 3, and the rotating assembly 4 includes a fixed frame 401, a servo motor 402, a rotating rod 403, a first gear 404, and a second gear 405. The fixed frame 401 is fixedly connected to the bottom side of the fixed plate 1, and the servo motor 402 is provided on the inner side of the fixed frame 401. The output shaft of the servo motor 402 is fixedly connected to the rotating rod 403 through a coupling, and the end of the rotating rod 403 is rotatably connected to the fixed plate 1. The first gear 404 is fixedly connected to the outer wall of the rotating rod 403, and the second gear 405 is meshed and rotatably connected to one side of the first gear 404. The second gear 405 is fixedly connected to the outer wall of the support plate 3, and both the first gear 404 and the second gear 405 are provided inside the fixed plate 1.

[0024] The specific operation is as follows: During the processing of the workpiece, the operator can use the rotating component 4 to rotate the support plate 3 set inside the fixed plate 1. The servo motor 402 set inside the fixed frame 401 drives the rotating rod 403 to rotate. As the rotating rod 403 rotates, the first gear 404 fixedly connected to its outer wall rotates accordingly, thereby causing the second gear 405, which meshes with the side of the first gear 404, to rotate as well. The second gear 405 is fixedly connected to the outer wall of the support plate 3, thereby causing the support plate 3 to rotate accordingly, thus realizing the rotation processing of the workpiece. The structure is simple and convenient for the operator to use the processing fixture.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the lifting rod 5 is welded to the four sides of the bottom of the support plate 3, and the bottom end of the lifting rod 5 is welded to the lifting plate 6. A limit assembly 7 is provided on the inner side of the support plate 3. The limit assembly 7 includes a drive motor 701, a limit screw 702, a lifting component 703, a rotating rod 704, a sliding block 705, a fixing rod 706, and a limit block 707. The drive motor 701 is located below the lifting plate 6, and the output shaft of the drive motor 701 is fixedly connected to the limit screw 702 via a coupling. The bottom end of the limit screw 702 is rotatably connected to the lifting plate 6, and the top end of the limit screw 702 is rotatably connected to the bottom center of the support plate 3. The lifting component 703 is rotatably connected to the outer side of the middle section of the limit screw 702 via a thread. Furthermore, the lifting component 703 is rotatably connected to four sides by rotating rods 704, and the other end of the rotating rods 704 is rotatably connected to a sliding block 705. A fixed rod 706 is connected through the center of the sliding block 705, and the end of the fixed rod 706 is welded to the inside of the support plate 3. A limit block 707 is welded to the top of the sliding block 705, and the limit block 707 is located above the support plate 3. A protective pad is fixedly adhered to the side of the limit block 707. An extension component 8 is engaged with the top of the limit block 707, and a capping component 9 is engaged with the top of the extension component 8. Square blocks 10 are welded to the sides of both the extension component 8 and the capping component 9, and the square blocks 10 are fixedly connected to the limit block 707 and the extension component 8 respectively by bolts.

[0026] The specific operation is as follows: The operator places the workpiece above the support plate 3, and then uses the limiting component 7 to limit the workpiece. The drive motor 701 drives the limiting screw 702 to rotate. As the limiting screw 702 rotates, the lifting component 703 connected to it by the thread moves downward. As the lifting component 703 descends, the rotating rod 704 connected to its four sides rotates at an angle, so that the sliding block 705 connected to the other end of the rotating rod 704 gradually engages and slides inside the support plate 3. Then, the limiting block 707 welded to the top of the sliding block 705 limits and clamps the side of the workpiece. In addition, the operator can increase the height of the limiting block 707 according to actual needs, and the heightening component 8 can be engaged above the limiting block 707. The top component 9 can also be engaged above the heightening component 8. The square block 10 welded to the side of the heightening component 8 and the top component 9 can be fixed with bolts. The structure is simple and convenient for the operator to use the processing fixture.

[0027] In summary, this CNC machining fixture for the cap is based on Figures 1-4 The structure shown illustrates that during CNC machining of the cap using a machining fixture, the operator first places the workpiece above the support plate 3. Then, the limiting component 7 limits the workpiece, and the drive motor 701 drives the limiting screw 702 to rotate. As the limiting screw 702 rotates, the lifting component 703, connected by a threaded connection on its outer side, moves downwards. As the lifting component 703 descends, the rotating rods 704, connected to its four sides, rotate at an angle. This causes the sliding block 705, rotatably connected to the other end of the rotating rod 704, to gradually engage and slide inside the support plate 3. This allows the limiting block 707, welded to the top of the sliding block 705, to clamp and limit the side of the workpiece. Furthermore, the operator can raise the limiting block 707 according to actual needs, by attaching the raised component 8. The upper part of the limiting block 707 can be engaged with the upper part of the sealing part 9 and the upper part of the heightening part 8. The square block 10 welded to the side of the heightening part 8 and the sealing part 9 can be fixed with bolts. In addition, during the processing of the workpiece, the operator can use the rotating component 4 to rotate the support plate 3 set inside the fixing plate 1. The servo motor 402 set inside the fixing frame 401 drives the rotating rod 403 to rotate. As the rotating rod 403 rotates, the first gear 404 fixedly connected to its outer wall rotates accordingly, so that the second gear 405 meshing with the side of the first gear 404 rotates accordingly. The second gear 405 is fixedly connected to the outer wall of the support plate 3, so that the support plate 3 rotates accordingly, thereby realizing the rotation processing of the workpiece. The structure is simple and convenient for the operator to use the processing fixture.
