Description

Technical Field

[0001] This invention relates to a tooling and processing technology suitable for machining multi-angle ultra-deep hole parts made of PP material. Background Technology

[0002] PP material is used as a basic component for semiconductor parts and is widely used because of its high strength and low weight. However, due to its material properties, it does not have the machinability of metal materials and cannot be processed using traditional clamping methods on processing equipment. This can easily lead to breakage during processing, affecting product quality.

[0003] On this basis, there will be complex structures that need to be processed on the equipment, especially the processing of ultra-deep holes. Generally, metal parts can only be considered ultra-deep holes if the aspect ratio exceeds 10. However, PP material itself has low heat resistance and high brittleness. If the aspect ratio exceeds 6-8, it will be considered an ultra-deep hole. Moreover, the size of semiconductor parts is constantly being reduced. Therefore, manufacturers often encounter ultra-deep hole processing with aspect ratios exceeding 8, and the processing diameter is only within 10mm, which further increases the processing difficulty.

[0004] Common ultra-deep hole drilling generally does not use vertical drill bits because vertical drilling is a conventional machining method. However, due to the size of ultra-deep holes, problems such as the inability to remove drilling debris and insufficient heat dissipation of the drill bit at depth cannot be encountered during the machining process. Therefore, deep hole drilling requires a near-horizontal drilling method to complete the process. As a result, the product needs to be drilled with the drilling equipment kept horizontal. At the same time, ultra-deep hole machining will also cause hole skew due to horizontal machining, further increasing the machining difficulty and product clamping difficulty, directly affecting the manufacturer's economic benefits. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a tooling and processing technology suitable for machining multi-angle ultra-deep hole parts made of PP material. The tooling fixes the product on the equipment so that it can be clamped and fixed on the equipment. At the same time, the rotating shaft of the equipment is used to rotate the product at multiple angles to meet the deep hole machining needs. Through the process design of deep hole machining, the difficulties encountered in the machining of ultra-deep holes are solved and the machining is realized.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a tooling and processing technology suitable for machining multi-angle ultra-deep hole parts made of PP material, including a positioning plate, which is located on the worktable of the machining equipment and is fixedly connected to the worktable by screws; an assembly plate is provided on the upper surface of the positioning plate, and the assembly plate forms a detachable fixed connection with the positioning plate; an assembly rivet is provided on the lower surface of the assembly plate, which cooperates with the positioning plate, and one end of the assembly rivet is connected to the interior of the assembly plate, while the other end is connected to an air source to achieve negative pressure fixation of the product to be produced; the assembly rivet includes a positioning section, a connecting section, and a vent hole; the positioning section is cylindrical and cooperates with the positioning plate; the connecting section is located below the positioning section and cooperates with the positioning plate to form a detachable fixed connection; the vent hole penetrates the entire assembly rivet and connects to the surface of the assembly plate.

[0007] Furthermore, the connecting segment includes an upper segment and a lower segment. The upper segment has a tapered shape from top to bottom, and the lower segment has a tapered shape from bottom to top. The minor diameters of the upper segment and the lower segment are opposite to each other and are fixedly connected.

[0008] Furthermore, the positioning plate is provided with positioning holes that cooperate with the assembly rivets. The positioning holes include an upper inner hole that cooperates with the positioning section and a lower inner hole that cooperates with the connecting section. The upper inner hole has a cylindrical inner diameter that cooperates with the positioning section on the assembly rivets to position the assembly plate. The lower inner hole is provided with a clamping spring, which is connected to the connecting section of the assembly rivets to fix the assembly rivets.

[0009] Furthermore, the assembly plate is provided with a positioning boss, which protrudes upward along the surface of the assembly plate to cooperate with the product to be processed.

[0010] Furthermore, the assembly plate is also provided with a connecting hole that penetrates the assembly plate and communicates with the bottom surface of the product. When the assembly rivet is ventilated, an air space is formed on the bottom surface of the product, allowing the product to be placed and removed at will. When the assembly rivet is de-ventilated, the airflow in the connecting hole is blocked, creating a negative pressure to lock the product.

[0011] Furthermore, the assembly plate is provided with a ventilation space that cooperates with the positioning plate. The ventilation space is located inside the assembly plate and is connected to the positioning plate. After the assembly rivet is de-aired, a negative pressure is formed in the ventilation space, which fixes the product to the assembly plate.

[0012] Furthermore, the positioning plate is provided with a negative pressure hole, which penetrates the positioning plate, extends upward, cooperates with the assembly plate, and connects to an air source to continuously provide negative pressure to the assembly plate.

[0013] Furthermore, multiple negative pressure holes are provided and arrayed on the positioning plate, corresponding one-to-one with the assembly plate. Each negative pressure hole is provided with a connecting pipe that passes through the positioning plate and cooperates with the assembly plate to form negative pressure within the assembly plate.

[0014] Furthermore, a machining process for multi-angle ultra-deep hole parts suitable for PP material is described below:

[0015] The first step is to install the assembly plate that matches the product onto the positioning plate, connect the assembly rivets to the positioning holes, and connect the external air source for ventilation.

[0016] The second step is to install the positioning plate on the equipment base and fix it to the equipment base.

[0017] The third step is to place the product on the assembly plate, disconnect the airflow from the assembly rivets, and lock the product in place.

[0018] The fourth step is to rotate the equipment base to adjust the product to a suitable drilling angle, typically a vertical or horizontal angle.

[0019] The fifth step is to perform preliminary hole machining on the product using a drill bit with a length-to-diameter ratio of less than 1:5.

[0020] The sixth step involves using a drill bit with a length-to-diameter ratio exceeding 1:10 to perform secondary machining on the hole, thus completing the deep hole machining.

[0021] Furthermore, in step six, the drill bit employs an internal cooling method.

[0022] Compared with existing technologies, this invention provides a tooling and processing technology suitable for machining multi-angle ultra-deep hole parts made of PP material. A positioning plate creates a clamping negative pressure on the assembly plate, and assembly rivets are used to position and fix the assembly plate. The negative pressure and positioning bosses determine the product position, and the positioning plate is then assembled onto the processing table of the equipment. The position of the product is adjusted by rotating the positioning plate. The processing technology ensures the machining accuracy of the deep holes, and internally cooled drill bits and staged drilling are used to achieve deep hole machining, improving machining accuracy and efficiency, thereby realizing multi-angle deep hole machining of PP material on the processing equipment.
