Description

Technical Field

[0001] This utility model relates to a groove-type process positioning structure, belonging to the field of metal die casting technology. Background Technology

[0002] In the traditional die-casting process of aluminum alloy filter housings, the complex shape and lack of effective positioning references make clamping difficult and prone to displacement deviations during machining, which can severely impact the dimensional accuracy and quality stability of the product. This led to the development of process bosses and process mounts, which are additional designs on the die-casting blank. Their function is to facilitate clamping during subsequent machining, ensuring the part is positioned and fixed. These process mounts are located at the edge of the blank and are used to fix it to the machine tool table during machining. After machining, the process mounts are removed.

[0003] However, traditional boss positioning processes are prone to inaccurate and unstable positioning when positioning irregularly shaped workpieces, leading to instability in machining dimensions, high production costs, and long production cycles. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0028] like Figure 1 As shown in the figure, this embodiment introduces a groove-type process positioning structure, including: a base plate 1, a die-cast part 2, and a pressure plate 3. The base plate 1 can be clamped and fixed to the CNC machine tool operation panel by a vise, and the die-cast part 2 is pressed and positioned by the pressure plate 3 to be fixed on the base plate 1. After the above positioning is completed, the die-cast part 2 can be processed by the CNC machine tool program setting table.

[0029] The die-cast part 2 has a process positioning groove on its side edge that cooperates with the pressure plate 3. The number of pressure plates 3 corresponds one-to-one with the number of process positioning grooves. Each pressure plate 3 is inserted into the process positioning groove from the top side downwards and gradually locked in place. Finally, the pressure plate 3 is fixed to the base plate 1 by screws 4, thereby fixing the die-cast part 2.

[0030] To improve positioning efficiency, in this embodiment, the interior of the process positioning groove adopts a gradually decreasing width structure, that is, the width gradually decreases from the top entrance of the process positioning groove inward. Therefore, the wider entrance facilitates the initial positioning operation, and the width gradually decreases as the depth increases, forming a precise guide and limit for the workpiece.

[0031] Furthermore, the design of process positioning grooves increases the heat dissipation area, which helps dissipate heat and thus makes the equipment performance more stable. Without affecting the overall structural strength, the design of process positioning grooves can reduce the weight of components, thereby reducing energy consumption or increasing carrying capacity. In the casting process, process positioning grooves can serve as mold parting surfaces or venting channels, facilitating the forming of metal, molten metal, or materials and improving the yield rate of the manufacturing process.

[0032] Furthermore, the surface of the process positioning groove in this embodiment is frosted, which can provide greater friction and higher stability for the fit between the process positioning groove and the pressure plate 3, so as to better clamp.

[0033] Furthermore, in one specific embodiment of this invention, process positioning grooves 2.1 are provided near the ends of opposite sides of the die-cast part 2. Similarly, a corresponding pressure plate 3 is provided for each process positioning groove 2.1. The four evenly distributed process positioning grooves 2.1 and the corresponding pressure plates 3 can be evenly stressed, thereby achieving stable locking and positioning of the die-cast part 2.

[0034] It should be noted that in this embodiment, multiple mounting holes can be positioned on the base plate 1. These mounting holes are compatible with screws 4, and one or more tooling fixtures can be placed for one-time processing according to actual production needs, thereby saving time and costs.

[0035] It should be further noted that in this embodiment, the die-cast part 2 is made of cast aluminum alloy, which has good strength, corrosion resistance, and machinability. It contains 10% silicon and a small amount of magnesium, which gives it the characteristics of low density and high strength. Furthermore, AlSi... 10 Mg aluminum alloy powder has the characteristics of high strength, low density, good fluidity and low shrinkage, making it a widely used material in the foundry industry.

[0036] Based on the above, similarly, the pressure plate 3 is made of aluminum with approximately the same hardness as the die-cast part 2, which avoids the pressure plate 3 being too hard and scratching the die-cast part 2. Furthermore, a through countersunk threaded hole 3.1 is provided on the pressure plate 3. This countersunk threaded hole 3.1 is compatible with the screw 4, which uses a countersunk screw. The taper of the countersunk threaded hole 3.1 is 118°, allowing for better contact with the countersunk screw, thus achieving precise positioning. The end of the pressure plate 3 is provided with a pressure head 3.2 that matches the process positioning groove. Both the pressure head 3.2 and the process positioning groove have a 1.5° draft angle, and the width gradually decreases as the depth increases, forming a precise guide and limit for the workpiece.

[0037] In addition, it should be added that in this embodiment, the base plate 1 is made of SUS304 stainless steel, which has excellent corrosion resistance, high temperature strength and creep strength, and stainless steel should also have good processing performance, and is widely used in the processing industry.

[0038] The novel high-efficiency process positioning groove structure provided in this embodiment involves the following steps in its application:

[0039] First, fix the base plate 1 onto the CNC machine tool control panel using a vise. Then, fit and tighten the pressure plate 3 into the corresponding process positioning grooves 2.1 on the die-cast part 2. Next, pass the screws 4 through the countersunk threaded holes 3.1 of the pressure plate 3 to fix the pressure plate 3 to the base plate 1. After adjusting the position, tighten each screw sequentially. After positioning, use the CNC machine tool's setting panel to complete the process. Figure 1 Machining work on die-cast part 2 on the left side of the middle. Example

[0040] Please see Figure 1 The difference between this embodiment and Embodiment 1 shown on the right side is that the die-cast part 2 can be positioned using its own positioning holes 2.3, and is fixed to the base plate 1 by direct drilling and screws 5. The base plate 1 has mounting holes that match the screws 5. Then, the pressure plate 3 and the die-cast part 2 are fixed to the base plate 1 by screws 4. Therefore, the positions can be adjusted sequentially and then tightened sequentially.

[0041] Specifically, in this embodiment, a process positioning groove 2.2 is provided at the middle position of each of the two opposite sides of the die casting 2, and a number of pressure plates 3 corresponding to the process positioning groove 2.2 are provided.

[0042] In addition, the number of positioning holes 2.3 is at least one, which is two in this embodiment, but in other embodiments it can be set to three or more according to actual needs.

[0043] The novel high-efficiency process positioning groove structure provided in this embodiment involves the following steps in its application:

[0044] First, fix the base plate 1 onto the CNC machine tool's operating panel using a vise. Position the die-cast part 2 using its own positioning holes 2.3, and then fix it to the base plate 1 using screws 5 through direct drilling. Next, fit and tighten the pressure plate 3 into the corresponding process positioning grooves 2.2 on the die-cast part 2. Then, pass screws 4 through the countersunk threaded holes 3.1 of the pressure plate 3 to fix the pressure plate 3 to the base plate 1. After adjusting the position, tighten each screw in turn. After positioning, use the CNC machine tool's setting panel to adjust the position. Figure 1 Machining work on die-cast part 2 on the right side of the middle.

[0045] It should be noted that you should refer to [link / reference]. Figure 1 Process positioning groove 1 2.1 and process positioning groove 2.2 can be set at the top and bottom of the die casting 1 respectively to facilitate the processing of the die casting 1 according to the requirements.

[0046] It should be noted that when using this utility model to make products in the same series, the position of the tooling can be slightly adjusted or individual parts can be processed according to the product size to achieve the effect of tooling sharing, which can save manpower and material costs.

[0047] In summary, the unique feature of this utility model is:

[0048] (1) Specific geometry and dimensional proportions of the process positioning groove. The process positioning groove adopts a gradually changing width structure. It is wider at the entrance end to facilitate initial positioning operations, and the width gradually decreases as the depth increases, forming a precise guide and limit for the workpiece. This design can effectively improve positioning accuracy, reduce workpiece displacement deviation during processing, and is suitable for processing various metal and non-metal materials. It can significantly improve production efficiency and reduce scrap rate.

[0049] (2) It can improve the performance of the product. Since electronic devices have high requirements for heat dissipation, the positioning groove design of this process can increase the heat dissipation area, which helps to dissipate heat and thus makes the performance of the equipment more stable.

[0050] (3) It can reduce product weight. Designing process positioning grooves on some parts can reduce the weight of the parts without affecting the overall structural strength, thereby reducing energy consumption or increasing carrying capacity.

[0051] (4) Facilitates processing and manufacturing. During the casting process, the process positioning groove can serve as the mold parting surface or venting channel, which helps to form molten metal or materials and improves the yield rate of the manufacturing process.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
