Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a processing fixture for reverse-mounted carbon fiber molding plates. Background Technology

[0002] Machining fixtures, as crucial auxiliary tools in manufacturing, play an irreplaceable role. In the past, without machining fixtures, product processing required leveling and alignment. This process, while capable of being completed in minutes with sufficient experience and skill, could take tens of minutes if not. If each product required this time, it would significantly impact production efficiency and hinder mass production. A good machining fixture can greatly reduce clamping time, improve product yield, ensure production efficiency, and reduce the reliance on operator experience for product quality.

[0003] With the continuous advancement of materials science and technology, the materials used in processing products have evolved from the original metals to include engineering plastics, carbon fiber, and glass fiber. However, this has also led to increased processing difficulty, more complex product shapes, anisotropic properties in some products, and insufficient rigidity, making clamping difficult.

[0004] For molded carbon fiber products, unlike injection-molded products which require mold closing before filling, there is often an issue of excess or insufficient material during the molding process. Furthermore, only the resin in carbon fiber itself possesses good fluidity. During mold closing, the material sheet clamped between the upper and lower molds raises the product cavity, altering the product's thickness and resulting in relatively poor consistency. Therefore, the upper mold cavity shape is often not used as the processing reference. If the lower mold cavity shape is used as the processing reference, there may be situations where the reference surface and the processing surface are not on the same plane, making processing impossible.

[0005] Because the formed products will warp, and the amount of warping of each product is different, it is impossible to provide support for the bottom of the processing position in a quantitative way. Moreover, during processing, the product will be pressed down by the tool due to being suspended in the air, and when it is released, it will spring back. Under these circumstances, the processed size will definitely not meet the requirements.

[0006] Considering that tooling is sometimes disassembled and then placed back on the workbench, the machine tool and tooling are often not parallel. This means that even if such tooling is machined as a whole, the workload and processing cost will increase significantly when it is reused, which is very unfavorable to the factory in terms of economy and production efficiency.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1-3 A processing fixture for reverse-mounted carbon fiber molding panels, specifically designed for reverse-mounted carbon fiber molding panels 14, aims to provide stable and precise support and positioning during their processing. Specifically:

[0021] The fixture includes a base plate 1, which serves as the base for the entire fixture, supporting and fixing other components to ensure the stability of the entire fixture structure.

[0022] Side support seats 2 are installed on both sides of the base plate 1 by locking screws 6 to ensure the reliability of the installation and facilitate disassembly and assembly. A reference plate 3 for pressing and engaging with the carbon fiber molding plate 14 is installed on the side support seats 2 by plug screws 4. The side support seats 2 provide a solid foundation for the subsequent installation of other components. The reference plate 3 plays a key positioning role in the processing. It presses and engages with the carbon fiber molding plate 14 to provide a stable upper surface reference for the carbon fiber molding plate 14, ensuring the positional accuracy and consistency of the carbon fiber molding plate 14 during the processing.

[0023] Preferably, the side support 2 is arranged vertically, and the bottom of the side support 2 is connected to the base plate 1 by a lower locking screw 6.

[0024] To facilitate the installation of the carbon fiber molding panel 14, a side inclined top block 8 is installed on the base plate 1 inside each side support 2 for cooperating with the top support of the carbon fiber molding panel 14. The side inclined top block 8 is connected to the base plate 1 through a positioning pin 9 and a side support spring 10. A side locking screw 5 is also installed on the side support 2 for locking and fixing the side inclined top block 8, so that the side inclined top block 8 can move up and down under the guidance of the positioning pin 9 and in cooperation with the side support spring 10, providing elastic support for the carbon fiber molding panel 14. After the carbon fiber molding panel 14 is installed, the side inclined top block 8 can be locked with the side locking screw 5 to provide stable support for the carbon fiber molding panel 14.

[0025] Preferably, the side support 2 is provided with a side notch that mates with the side locking screw 5, and the side inclined top block 8 is provided with a side threaded hole that mates with the side locking screw 5. This design provides space for the installation and operation of the side locking screw 5, and facilitates the locking and fixing of the side inclined top block 8. The reference plate 3 is arranged horizontally and is installed on the top of the side support 2 by the plug screw 4. It is used to provide an upper positioning reference for the carbon fiber molding plate 14 and ensure dimensional accuracy during processing.

[0026] Both the side support spring 10 and the positioning pin 9 are vertically arranged. The positioning pin 9 is fixedly installed at the bottom of the side inclined block 8. The side support spring 10 is fitted onto the positioning pin 9, and the bottom of the side support spring 10 is fixedly connected to the base plate 1. The base plate 1 is also provided with an opening that cooperates with the positioning pin 9, so that the side inclined block 8 can move up and down under the guidance of the positioning pin 9. At the same time, the side support spring 10 provides elastic support force for it. The opening is provided to provide sufficient space for the up and down movement of the positioning pin 9.

[0027] Furthermore, in order to better support the carbon fiber molding plate 14, a middle inclined top block 7 is installed in the middle of the base plate 1 for cooperating with the top support of the carbon fiber molding plate 14. The middle inclined top block 7 is fixedly connected to the base plate 1 through the middle support spring 11, so that it can move up and down within a certain range. A middle support seat 12 is also installed in the middle of the base plate 1. A middle locking screw 13 is installed on the middle support seat 12 for locking and fixing with the middle inclined top block 7. The middle inclined top block 7 is used to cooperate with the top support of the carbon fiber molding plate 14 and works together with the side inclined top block 8 to support and position the carbon fiber molding plate 14 from different positions.

[0028] Preferably, the intermediate support 12 is provided with an intermediate notch that mates with the intermediate locking screw 13, and the intermediate inclined top block 7 is provided with an intermediate threaded hole that mates with the intermediate locking screw 13. After the carbon fiber molding plate 14 is positioned, the intermediate locking screw 13 is screwed into the intermediate threaded hole through the intermediate notch to lock and fix the intermediate inclined top block 7, thereby ensuring the stability of the carbon fiber molding plate 14 during the processing.

[0029] The wire diameter of the side support spring 10 and the middle support spring 11 is between 0.8 and 0.6 mm, so that its supporting force can fully lift the carbon fiber molding plate 14 without squeezing and deforming it, while making it easy for the operator to press and pick up the material.

[0030] The base plate 1, reference plate 3, side support seat 2, middle support seat 12, side inclined top block 8, and middle inclined top block 7 are all made of metal and are selected from any one of carbon steel, stainless steel, copper, aluminum alloy, and titanium alloy. They have high strength, good rigidity and wear resistance, and can withstand various forces and vibrations during the processing, ensuring the reliability of the fixture for long-term use.

[0031] The process of using the processing fixture for the reverse-mounted carbon fiber molding panel provided in this application is as follows:

[0032] The carbon fiber molding plate 14 applicable to this application is generally inclined, with one side being thicker than the other. Grooves 15 are provided on both sides of the lower mold surface 16. This special-shaped carbon fiber molding plate 14 requires a specific installation method during processing. The design of this application is precisely to meet these processing requirements, enabling the carbon fiber molding plate 14 to be installed in reverse to facilitate processing of the central processing position 17 of the lower mold surface 16. Specifically:

[0033] First, press the carbon fiber molding plate 14 against the side inclined top block 8 and the middle inclined top block 7, and then press it down so that the side inclined top block 8 moves up and down under the guidance of the positioning pin 9 until the distance between the side inclined top block 8, the carbon fiber molding plate 14 and the reference plate 3 can pass through the carbon fiber molding plate 14. Then push the carbon fiber molding plate 14 inward. During the movement of the carbon fiber molding plate 14, under the action of the side support spring 10 and the middle support spring 11, the carbon fiber molding plate 14 can fit with the reference plate 3 at the position of the two side grooves 15.

[0034] After positioning, the side inclined top block 8 and the middle inclined top block 7 are locked using the side locking screw 5 and the middle locking screw 13. Due to the action of the side support spring 10 and the middle support spring 11, the side inclined top block 8 and the middle inclined top block 7 are tightly attached to the carbon fiber molding plate 14. After locking, the carbon fiber molding plate 14 is supported to ensure the reliability of the installation of the carbon fiber molding plate 14 and facilitate the processing of the middle processing position 17 of its lower mold surface 16.

[0035] After processing, loosen the side inclined top block 8 and the middle inclined top block 7 by using the side locking screw 5 and the middle locking screw 13. Then, press the carbon fiber molding plate 14 downwards and towards the operator (e.g., towards the direction of the operator).
