Description

Technical Field

[0001] This utility model relates to the field of material cutting technology, specifically to a positioning and milling device for composite material finished products. Background Technology

[0002] Existing methods for cutting composite materials include manual cutting using handheld hot wire cutters, which relies heavily on the operator's skill and experience, with cutting accuracy directly affected by the operator's skill. Alternatively, there is automated cutting technology using laser cutting machines combined with CNC control systems, known for its high precision and efficiency, but requiring significant equipment investment and detailed data preparation. Traditional mold-forming technology ensures product consistency through molds and is suitable for mass production, but lacks flexibility for small-batch and diverse production needs. Robotic arms equipped with specialized cutting tools achieve automated cutting through programmed preset motion trajectories, making them particularly suitable for high-repetition and precision machining requirements.

[0003] However, all of the above cutting technologies have certain limitations. Using handheld hot wire cutters is highly dependent on technical skills, which can easily lead to insufficient cutting accuracy and operational errors, increasing employee training costs and reducing production efficiency. While laser cutting machines offer high precision and efficiency, their high equipment cost and complex data preparation process make them less economical for small-batch, diversified product production.

[0004] Traditional mold forming technology excels in ensuring product consistency, but lacks flexibility for small-batch, multi-variety production. While robotic arms using specialized cutting tools meet the requirements of high repeatability and precision, their complex programming settings also limit their adaptability to diverse small-batch needs. Existing cutting technologies struggle to meet the stringent requirements of composite material finished products for positional accuracy, hole accuracy, and dimensional accuracy, and face challenges in improving production efficiency and reducing costs. Utility Model Content

[0005] In order to solve the problems and defects of the prior art, this utility model provides a positioning and milling device for composite material finished products, which aims to effectively ensure the positional accuracy and dimensional accuracy of the core and hole positions of the parts, save manpower, and improve work efficiency.

[0006] This utility model discloses a positioning and milling device for composite material finished products. The positioning template is provided with a foam core positioning groove, a part cutting groove, and a part cutting positioning groove. The drilling template is installed on the positioning template through drilling template mounting holes. The drilling template is T-shaped, with a large hole milling groove in the middle, which is correspondingly located within the range of the part cutting groove. Ear plates extend outward from both sides of the drilling template, and small hole drilling bushings are provided on the ear plates, which are located within the range of the foam core positioning groove. The part cutting positioning groove is used to position the workpiece to be cut.

[0007] As a further improvement of this utility model, the large hole milling groove of the drilling template is used in conjunction with the small hole drilling bushing for drilling operations on the workpiece.

[0008] As a further improvement of this utility model, the positioning template is also provided with light-reducing and hanging holes.

[0009] As a further improvement of this utility model, the shape of the foam core positioning groove is matched with the foam core to be positioned.

[0010] As a further improvement of this utility model, the shape of the part cutting positioning groove matches the contour of the workpiece to be cut.

[0011] As a further improvement of this utility model, the number and position of the drilling template mounting holes correspond one-to-one with the holes on the positioning template.

[0012] As a further improvement of this utility model, the shape of the large hole milling groove is adapted to the maximum size of the hole to be made.

[0013] As a further improvement of this utility model, the inner diameter of the small hole drilling bushing is matched with the required hole diameter.

[0014] As a further improvement of this utility model, the size of the part cutting groove is larger than the size of the large hole milling groove.

[0015] As a further improvement of this utility model, the drill template is provided with a drill template seat in the thickness direction.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This invention provides a complete device structure for positioning and milling composite material products through the foam core positioning groove and part cutting positioning groove on the positioning template, as well as the large hole milling groove and small hole drilling bushing on the drilling template. The positioning template can position the foam core and the workpiece to be cut, ensuring the accuracy of the workpiece's position during processing; after the drilling template is installed on the positioning template, its structure can be used for subsequent milling and drilling operations, improving the standardization and efficiency of composite material product processing and ensuring processing quality.

[0017] The large-hole milling groove of the drilling template is used in conjunction with the small-hole drilling bushing. When drilling a workpiece, the large-hole milling groove can provide suitable space and guidance for milling large holes, while the small-hole drilling bushing can ensure the accuracy of small-hole drilling. The two work together to improve the accuracy and efficiency of drilling operations and meet the processing needs of holes of different sizes.

[0018] The positioning template has light-reducing and hanging holes, which on the one hand reduces the weight of the positioning template itself, making it easier for operators to move and install the positioning template and reducing labor intensity; on the other hand, the light-reducing and hanging holes provide convenience for the storage of the positioning template, which can be stored by hanging, saving space.

[0019] The shape of the foam core positioning groove matches the foam core to be positioned, enabling the foam core to be accurately positioned on the positioning template. This ensures that the foam core remains in a fixed position during subsequent processing and will not move, thereby guaranteeing the accuracy of processing steps related to the foam core and improving the overall quality of the finished composite material.

[0020] The shape of the positioning groove for part cutting matches the contour of the workpiece to be cut, providing a precise positioning reference. During the cutting process, the workpiece can be precisely cut according to the contour of the positioning groove, ensuring the accuracy of the cutting dimensions and the neatness of the cutting edges, thereby improving the machining accuracy and quality of the workpiece.

[0021] The number and position of the drilling template mounting holes correspond one-to-one with the holes on the positioning template, ensuring that the drilling template can be accurately installed on the positioning template. The installation process is simple and quick, and the relative position between the drilling template and the positioning template is fixed after installation, providing a stable reference for subsequent milling and drilling operations, which is conducive to improving machining accuracy and product quality.

[0022] The shape of the large hole milling groove is adapted to the maximum size of the hole to be made, so that the milling tool can operate in a suitable space when milling large holes, avoiding the problem of milling difficulties or poor processing quality due to insufficient space. At the same time, it can also ensure that the size of the milled large hole meets the requirements, improving the accuracy and efficiency of hole making.

[0023] The inner diameter of the small hole drilling bushing matches the required hole diameter, providing precise guidance for the drill bit during drilling, ensuring accurate hole diameter, reducing drill bit wobble, improving hole perpendicularity and surface quality, and ensuring the machining accuracy of the small hole.

[0024] The part cutting groove is larger than the large hole milling groove, providing more space for the cutting operation. During the cutting process, the cutting tool can move more freely, avoiding interference with the large hole milling groove or other components due to limited space, ensuring smooth cutting operation, and improving cutting efficiency and safety.

[0025] The drill template has a drill template seat in the thickness direction, which makes it easier for operators to install, position, and disassemble the drill template, reducing labor intensity. It also facilitates the overall operation and adjustment of the device, improving work efficiency. Attached Figure Description
