[0001] This utility model belongs to the field of positioning fixtures for die-casting parts, specifically a positioning fixture for die-casting parts. Background Technology
[0002] Die castings are parts produced by pressure casting. They are made using a pressure casting machine equipped with a casting mold. Molten copper, zinc, aluminum, or aluminum alloy is poured into the machine's feed inlet, and then the machine presses and casts the copper, zinc, aluminum, or aluminum alloy parts into shapes and sizes defined by the mold. These parts are commonly called die castings. Die castings have different names in different places, such as die casting parts, pressure castings, die castings, die casting aluminum, die casting zinc, die casting copper, copper die casting, zinc die casting, aluminum die casting, aluminum alloy die casting, and aluminum alloy die casting parts.
[0003] Before machining die-cast mechanical parts on a machine tool, the parts usually need to be aligned on the worktable using three points to determine the spatial position of the workpiece, tool, and clamping plate before machining. The alignment, clamping, and disassembly process is usually quite cumbersome. When the workpiece is a complex irregular part, it often consumes a lot of non-machining time, affecting work efficiency. Each part needs to be clamped before machining, and human factors may cause unstable quality or even lead to scrap.
[0004] Therefore, this utility model provides a positioning fixture for die-cast parts. Utility Model Content

[0026] Specifically, the operator places the part to be processed onto the upper surface of the workbench 1. The hydraulic cylinder 2 installed inside the workbench 1 is activated. The hydraulic cylinder 2 is an existing electrical component, and the AHP standard hydraulic cylinder 2 can be referenced. The working principle of the hydraulic cylinder 2 is existing technology and will not be elaborated here. The output end of the hydraulic cylinder 2 is fixedly connected to a telescopic rod 3. The output end of the hydraulic cylinder 2 drives the telescopic rod 3 to reciprocate. A clamping body 41 is fixedly installed at one end of the telescopic rod 3. Two sets of rotating supports 42 are movably connected to both sides of the clamping body 41. Clamping arms 44 are movably installed on the outer sides of the two sets of rotating supports 42 respectively. A cylinder 43 is fixedly connected inside the clamping arm 44. Both ends of the cylinder 43 are fixedly installed inside the rotating disk 6. A multi-point clamping block 45 is fixedly installed on one side of the clamping arm 44. A movable groove is opened inside the multi-point clamping block 45, and a guide post 46 is fixedly installed inside the movable groove. A spring 47 is installed on the outside of the guide post 46. One end of the spring 47 is installed on the inner wall of the multi-point clamping block 45, and the other end of the spring 47 is installed on a movable post 48. The output end of the hydraulic cylinder 2 drives the telescopic rod 3 to reciprocate. The telescopic rod 3 drives the clamping body 41 to move horizontally. The clamping body 41 pushes the rotating support 42, causing it to rotate... The movable support 42 causes the clamping arm 44 to perform clamping and retracting movements. A multi-point clamping block 45 mounted on one side of the clamping arm 44 contacts the part, causing the movable column 48 installed inside the multi-point clamping block 45 to contact the part surface. Different parts have different surface shapes and clamping states. When the movable column 48 contacts the part, the spring 47 is compressed, and the movable column 48 slides outside the guide column 46, thus achieving clamping of parts with different shapes. During part processing, it is necessary to observe the situation to prevent processing errors that could damage the part. Two sets of cylinders 43 are respectively installed inside the rotating disk 6, which is located on the ring 7. Inside the inner groove 9, when it is necessary to rotate and observe the part, the clamping arm 44 is rotated.

A lead screw 11 is movably connected inside the slider 10. The lead screw 11 is located in the groove 8 on the upper surface of the operating table 1. Thus, when the output end of the hydraulic cylinder 2 drives the telescopic rod 3 to reciprocate, the slider 10 moves smoothly outside the lead screw 11, thereby achieving stable fixation of the clamping device 4.
[0027] like Figure 2 As shown, a slide groove 8 is provided on the upper surface of the operating table 1, and the lead screw 11 is located inside the slide groove 8.

A lead screw 11 is movably connected inside the slider 10. The lead screw 11 is located in the groove 8 opened on the upper surface of the operating table 1. Thus, when the output end of the hydraulic cylinder 2 drives the telescopic rod 3 to reciprocate, the slider 10 moves smoothly outside the lead screw 11, thereby achieving stable fixation of the clamping device 4.
[0029] like Figure 2 As shown, a second groove 9 is provided inside the ring 7, and a rotating disk 6 is slidably connected inside the second groove 9. The rotating disk 6 slides inside the ring 7.
[0030] Specifically, during the processing of parts, it is necessary to observe their condition to prevent processing errors from causing damage to the parts. Two sets of cylinders 43 are installed inside the rotating disk 6. The rotating disk 6 is located inside the sliding groove 9 opened inside the ring 7. When it is necessary to rotate and observe the parts, the clamping arm 44 is rotated. The clamping arm 44 drives the rotating disk 6 to rotate in the sliding groove 9 opened inside the ring 7, thereby realizing the observation of the processed parts.
[0031] like Figures 1 to 2 As shown, one end of the control panel 1 has a mounting groove, and the hydraulic cylinder 2 is fixedly installed inside the control panel 1 through the mounting groove.
[0032] Specifically, the hydraulic cylinder 2 is an existing electrical device, and the AHP standard hydraulic cylinder 2 can be referenced. The working principle of the hydraulic cylinder 2 is existing technology and will not be elaborated in this case. One end of the operating table 1 is provided with a mounting groove, and the hydraulic cylinder 2 is installed inside the mounting groove, thereby effectively reducing the vibration generated by the hydraulic cylinder 2 during operation.
[0033] like Figures 1 to 3 As shown, two sets of clamping arms 44 are symmetrically arranged along the central axis of the clamping body 41, and two sets of clamping devices 4 and hydraulic cylinders 2 are symmetrically arranged along the central axis of the operating table 1.
[0034] Specifically, two sets of clamping devices 4 and hydraulic cylinders 2 are respectively provided on the upper surface of the operating table 1.

A guide column 46 is provided inside the multi-point clamping block 45. A spring 47 is provided on the outer side of the guide column 46. One end of the spring 47 is fixedly connected to the movable column 48.
[0037] Specifically, the telescopic rod 3 drives the clamping body 41 to move horizontally, the clamping body 41 pushes the rotating support 42, the rotating support 42 causes the clamping arm 44 to perform clamping and retracting movements, the multi-point clamping block 45 installed on one side of the clamping arm 44 contacts the part, so that the movable column 48 installed inside the multi-point clamping block 45 contacts the surface of the part. Different parts have different surface shapes and clamping states. When the movable column 48 contacts the part, the spring 47 is compressed, and the movable column 48 slides outside the guide column 46, thereby achieving clamping of parts of different shapes. When processing the part, it is necessary to observe its condition to prevent processing errors from causing damage to the part.
[0038] Working principle: The operator places the part to be processed on the upper surface of the operating table 1. The hydraulic cylinder 2 installed inside the operating table 1 is activated. The hydraulic cylinder 2 is an existing electrical device, and the AHP standard hydraulic cylinder 2 can be referenced. The working principle of the hydraulic cylinder 2 is existing technology and will not be elaborated here. The output end of the hydraulic cylinder 2 is fixedly connected to the telescopic rod 3. The output end of the hydraulic cylinder 2 drives the telescopic rod 3 to reciprocate. The telescopic rod 3 drives the clamping body 41 to move horizontally. The clamping body 41 pushes the rotating support 42. The rotating support 42 causes the clamping arm 44 to perform clamping and retracting movements. The multi-point clamping block 45 installed on one side of the clamping arm 44 contacts the part, so the movable column 48 installed inside the multi-point clamping block 45 contacts the surface of the part. Different parts have different surface shapes and clamping states. When the movable column 48 contacts the part, the spring 47 is compressed. 8 slides outside the guide post 46 to clamp parts of different shapes. When processing parts, it is necessary to observe their condition to prevent damage caused by processing errors. Two sets of cylinders 43 are installed inside the rotating disk 6. The rotating disk 6 is located inside the second slide groove 9 opened inside the ring 7. When it is necessary to rotate and observe the parts, rotate the clamping arm 44. The clamping arm 44 drives the rotating disk 6 to rotate in the second slide groove 9 opened inside the ring 7, thereby enabling observation of the processed parts.
