Description

Technical Field

[0001] The utility model belongs to the field of fiber reinforced resin-based composite material processing and relates to an integrated tooling for milling and hole making of composite material components. Background Art

[0002] At present, more and more products on the market tend to use fiber-reinforced resin-based composite materials to replace traditional metal materials. The molding and processing of composite parts directly determine the comprehensive performance of the product. At first, the processing methods of composite parts mainly include: manual processing according to the corresponding edges left on the parts by the engraved lines on the mold when the parts are formed, or processing using machine tools (such as CNC milling machines, laser engraving machines, water jet cutting machines, etc.). If machine tools are used for processing, the cost is high, and the dust generated during the processing will damage the equipment. Later, devices that assist manual processing were gradually developed to overcome the problem of external processing defects such as wavy lines and serrated lines on the cutting edge, and improve the efficiency of trimming. The invention patent with application publication number CN105619480A introduces a composite material trimming tool that assists manual processing, but the device can only be used for trimming, and fails to combine precise hole making and precise trimming in one device. The function is not perfect and the efficiency needs to be improved.

[0003] In order to improve the processing efficiency of composite materials, there is still a lack of an integrated tooling that can simultaneously complete precise hole making and precise edge trimming. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the existing equipment fails to combine precise hole making and precise edge trimming in one device. In order to overcome the deficiencies and defects mentioned in the above background technology, an integrated tooling for manual milling and hole making of composite materials is provided.

[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is:

[0006] An integrated tool for manual milling and hole making of composite materials, characterized in that the integrated tool comprises a drilling template, a backing template, a quick clamp, a positioning support plate and a bottom frame, the drilling template, the backing template and the quick clamp are mounted on the positioning support plate, and the positioning support plate is arranged on the bottom frame;

[0007] The integrated tooling is equipped with a milling cutter, which includes a pineapple milling cutter, an adapter and a pneumatic milling tool. The pineapple milling cutter and the adapter are installed on the pneumatic milling tool.

[0008] When in use, flip or remove the template and drilling template and reset the positioning clamp to avoid placing the material to be processed, place the material to be processed on the positioning support plate of the tooling, position it close to the positioning support plate, lower the quick clamp to clamp the material to be processed, flip or install the template and drilling template, make holes according to the drilling template, and use a milling tool to mill the end surface contours of the material to be processed based on the template.

[0009] The existing cutting and hole making of special-shaped composite materials have no benchmarks, and the machining cost is high. This application establishes a benchmark on the tooling to ensure the positioning of the parts, and then manually cuts the shape of the parts and makes holes in one go to ensure the accuracy of the parts without relying on machine tools. The integrated tooling structure of this application can simultaneously cut edges and make holes on both ends of special-shaped composite materials on the same tooling, ensuring accuracy, improving efficiency, and reducing the cost of machining.

[0010] Preferably, the integrated tooling also includes a side drilling template arranged on the positioning support plate, which can simultaneously make holes on the side of the part.

[0011] Preferably, the pineapple milling cutter passes through an adapter, and the adapter cooperates with the backing plate. Preferably, the length of the pineapple milling cutter is greater than the sum of the thickness of the backing plate and the processed product.

[0012] Preferably, one or more support plates (2) are provided.

[0013] Preferably, a support plate (2) is provided at each end of the positioning support plate (4).

[0014] More preferably, each support plate is positioned by two latches to facilitate disassembly.

[0015] Preferably, the drilling template (1) and the support template (2) both comprise a hole-making module.

[0016] If it is necessary to make a hole near the end of the product, the template and the drilling template are designed together, which can serve as the drilling template to assist in making holes and also as the template to mill the product shape.

[0017] Preferably, the drilling template and the supporting template are designed to be flippable to facilitate disassembly and assembly of the product.

[0018] Preferably, 3-5 quick clamps are arranged on the positioning support plate, and the quick clamps are evenly distributed in the length direction of the positioning support plate.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The utility model discloses an integrated tool for manual precision milling and hole making for composite material components. With the tool, precise hole making and precise milling of the shape of the product can be achieved by manual operation only, saving expensive equipment processing costs. On the integrated tool, precise hole making and precise milling of the shape can be performed at the same time. Hole making and milling are performed in one process without the need to change tooling, which greatly improves efficiency and saves the cost of tooling processing. BRIEF DESCRIPTION OF THE DRAWINGS

The drilling template 1, the backing template 2, the side drilling template 6, and the quick clamp 3 are all positioned by pins and installed on the positioning support plate 4, and the positioning support plate 4 is welded to the bottom frame 5. Before processing the material 8 to be processed, the material 8 to be processed is placed close to the positioning support plate 4. After confirming that there is a milling margin at both ends of the material 8 to be processed according to the contours of the two ends of the positioning support plate 4, the quick clamp 3 is used to clamp the material 8 to be processed, and a milling tool circulated on the market is used to cooperate with the drilling template 1, the backing template 2, and the side drilling template 6 to make holes and mill the material 8 to be processed.

[0032] The milling cutting tool of the utility model relies on the milling cutting principle diagram of the composite material manual milling hole integrated tooling on the template. Figure 2 to Figure 4 As shown, the pineapple milling cutter 7 and the adapter 9 are installed on the pneumatic milling tool, which is a pneumatic milling tool of the DOTCO brand under Cooper Corporation. After the product is positioned and clamped, the pineapple milling cutter 7 passes through the adapter 9, and after the compressed air power is turned on, the milling tool is placed close to the template 2 and moves along the contour of the template 2 for one circle to complete the milling of the product shape.

[0033] In this embodiment, the drilling template 1 also serves as the supporting template 2, and a single template can be used to make holes and mill the shape of one end of the product, thereby saving manufacturing costs, simplifying the use of tooling, and eliminating the need to frequently replace templates.

[0034] In this embodiment, the drilling template 1 and the support template 2 both serve as support templates, and the outer contours of both ends of the product can be milled by using the tooling.

[0035] In this embodiment, the drilling template 1 and the side drilling template 6 assist in hole making. On this tooling, the drilling template 1 can be used to process the holes on the upper and lower surfaces and the sides of the product.

[0036] In this embodiment, on the integrated tooling, precise hole making and precise milling of the product's shape can be performed simultaneously by manual operation only. The hole making and milling are performed in one process without the need to change tooling, which greatly improves efficiency and completely saves the cost of using equipment to process products.
