Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, and in particular to a cutting fixture for curved foam boards. Background Technology

[0002] When machining foam boards using CNC cutting, the foam boards usually need to be mounted on corresponding tooling for multiple processing steps. Since foam boards are flexible materials, they are prone to deformation during processing, which affects the processing accuracy. Therefore, the requirements for tooling fixtures for foam boards are high. Conventional tooling fixtures are only suitable for cutting metal workpieces and are difficult to apply to flexible materials such as foam boards.

[0003] Currently, Chinese Patent Publication No. CN220561676U discloses a special fixture for cutting foam molds, including an operating table. Fixed frames are fixedly connected to both sides of the top of the operating table. A rotating screw is movably sleeved in the middle of the fixed frame. A rear gear is movably sleeved in the middle of the rotating screw. A front gear meshes with the front of the rear gear. A power motor is movably connected to one side of the front gear. A connecting frame is fixedly connected to the other side of the rotating screw. A first rotating ring is movably connected to the other side of the connecting frame. A second rotating ring is movably connected to the other side of the first rotating ring. A third rotating ring is movably connected to the other side of the second rotating ring.

[0004] Although this special fixture for cutting foam molds can hold and fix foam boards, it is only suitable for flat foam boards. It is still difficult to fix curved or other irregularly shaped foam boards. When cutting the end face of curved foam boards, the flexible material of the foam board makes the board itself very easy to deform, which will affect the cutting accuracy of the foam board. Especially for relatively thin boards, this fixture and existing foam board fixtures are not suitable for cutting curved foam boards. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a cutting fixture for curved foam boards, which solves the problems of inconvenience and low machining accuracy of cutting the end face of curved foam boards in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a cutting fixture for a curved foam board, including a board body, a through hole at the center of the board body, and cutting end faces around the board body. The inner surface of the board body is curved. The cutting fixture includes a base, a positioning post on the base for fitting into the through hole, and a pressure plate on the upper end of the positioning post for pressing the board body from top to bottom. The upper end face of the base is a curved surface adapted to the shape of the inner surface of the board body, and the side wall of the base is configured as a positioning end face flush with the cutting end face of the board body.

[0007] By adopting the above technical solution, when processing curved foam boards, through holes can be machined on the board body first through a cutting process. Then, the board body with through holes is installed on the base, and the lower side of the board body is attached to the upper end face of the base. The board body is then fixed on the base by a pressure plate, and the side wall of the base serves as the positioning end face for cutting the board body. This allows the side wall of the base to serve as a reference during cutting, thereby ensuring the machining accuracy of the board body end face. Moreover, the pressure plate and the base ensure that the position of the board body will not shift during processing, further improving the machining accuracy. The quick positioning of the machining end face by the base makes positioning easier and can further improve the processing efficiency.

[0008] In one embodiment of this utility model, the length of the positioning post is greater than the thickness of the plate, and multiple plates can be fitted over the positioning post.

[0009] By adopting the above technical solution, multiple plates with through holes can be simultaneously mounted on the base, and multiple plates can be processed in one process, which greatly improves the processing efficiency of the plates.

[0010] In one embodiment of the present invention, the pressure plate includes a collar that can be sleeved on the outside of the positioning post and abut against the upper end surface of the plate body, and a connecting block fixedly connected to the upper side of the collar and located at the upper end of the positioning post. The lower end surface of the collar is adapted to the shape of the upper end surface of the plate body.

[0011] By adopting the above technical solution, the shape of the lower end face of the collar is adapted to the shape of the upper end face of the plate, which makes it fit the plate better, resulting in a better pressing effect. It also makes the plate more uniformly stressed, preventing structural deformation and ensuring processing accuracy.

[0012] In one embodiment of the present invention, a fastening bolt is further included to connect the positioning post and the connecting block. The connecting block has a connecting hole for the fastening bolt to pass through, and the upper end of the positioning post is provided with a threaded hole that engages with the thread of the fastening bolt.

[0013] By adopting the above technical solution, the fastening bolt connecting block can be fixedly installed on the upper side of the positioning column, ensuring that the position of the plate on the base will not shift during the handling of the tooling, thus ensuring the fixing effect. Moreover, the use of screw connection makes it easier to disassemble and assemble, and the structure is simple and reliable.

[0014] In one embodiment of this utility model, the collar sidewall is located inside the base sidewall.

[0015] By adopting the above technical solution, the side wall of the collar is located inside the positioning end face, which will not affect the positioning cutting end face of the cutting mechanism and will not cause interference.

[0016] In one embodiment of the present invention, an arc-shaped groove is provided on the upper side of the connecting block, and multiple arc-shaped grooves are provided and evenly distributed around the center of the pressure plate.

[0017] By adopting the above technical solution and using multiple arc-shaped grooves, the connecting block structure becomes lighter, easier to disassemble, and easier to pick up and put down.

[0018] As described above, the cutting fixture for curved foam boards of this utility model has the following beneficial effects: When processing curved foam boards, the through holes on the board body can be processed first through a cutting process, and then the board body with through holes can be installed on the base accordingly, with the lower side of the board body fitting against the upper end face of the base. Then, the board body is fixedly installed on the base by a pressure plate, and the side wall of the base serves as the positioning end face for cutting the board body. This allows the side wall of the base to serve as a reference during cutting, thereby ensuring the processing accuracy of the board body end face. Moreover, the pressure plate, in conjunction with the base, ensures that the position of the board body will not shift during processing, further improving the processing accuracy. Furthermore, the quick positioning of the processing end face by the base makes positioning easier, further improving the processing efficiency. Attached Figure Description

[0028] like Figure 1 , Figure 2 As shown, this utility model provides a curved foam board, including a board body 1, a through hole 2 disposed at the center of the board body 1, and a cut end face 3 disposed around the board body 1. The inner side of the board body 1 is curved.

[0029] The plate 1 is in the shape of a ring or a cone. During processing, the through hole 2 at the center of the plate 1 is first machined by cutting process. Then the plate 1 with the through hole 2 is placed on the corresponding tooling and the cutting end face 3 is machined by cutting process. Example

[0030] like Figure 3 , Figure 4 As shown, this embodiment provides a cutting fixture for a curved foam board as described in Embodiment 1, including a base 4, a positioning post 5 disposed on the base 4 for fitting through the through hole 2, and a pressure plate 6 disposed on the upper end of the positioning post 5 to press the board body 1 from top to bottom. The upper end surface of the base 4 is a curved surface adapted to the shape of the inner side surface of the board body 1, and the side wall of the base 4 is configured as a positioning end surface that is flush with the cutting end surface 3 of the board body 1.

[0031] The length of the positioning post 5 is greater than the thickness of the plate 1. Multiple plates 1 can be sleeved on the positioning post 5 along the same axis, so that multiple plates 1 can be sleeved on a base 4 at the same time, and multiple plates 1 can be processed in one processing step.

[0032] The pressure plate 6 includes a collar 10 that can be fitted over the positioning post 5 and abut against the upper end face of the plate body 1, and a connecting block 11 that is fixedly connected to the upper side of the collar 10 and located at the upper end of the positioning post 5.
