Description

Technical Field

[0001] This utility model relates to the field of machining fixtures, and in particular to a steel piston automatic alignment dual-station multi-angle drilling and boring fixture. Background Technology

[0002] In the field of mechanical manufacturing, steel pistons are key components of equipment such as engines. Their machining accuracy and efficiency are crucial to the overall performance of the equipment. After the steel piston blank is forged, a series of complex machining processes are required, such as machining the outer circle, oil passages, combustion chamber, as well as drilling oil holes and boring pin holes.

[0003] Traditional steel piston machining methods have many drawbacks: outdated positioning and machining techniques rely on manual clamping, resulting in significant positional deviations and making it difficult to guarantee the machining accuracy of the steel piston, thus affecting its performance in engines and other equipment; cumbersome processes, such as drilling angled oil holes, which require different angles, necessitate multiple processes, multiple machines, and multiple people working together. For example, the previous process involved four steps: drilling straight holes, boring, drilling angled oil holes, and drilling angled oil holes again, requiring two machines and two people to work together. This not only led to low production efficiency but also significantly increased production costs. The lack of efficient machining equipment and tooling prevented a single machine from completing multi-angle machining, limiting the improvement of production efficiency.

[0004] Therefore, it is necessary to provide a steel piston automatic alignment dual-station multi-angle drilling and boring fixture to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a dual-station, multi-angle drilling and boring fixture for automatic alignment of steel pistons, which solves the problems of outdated positioning methods, cumbersome procedures, and inefficient processing equipment and tooling in traditional steel piston processing.

[0006] To solve the above-mentioned technical problems, this utility model provides a steel piston automatic alignment dual-station multi-angle drilling and boring fixture, comprising:

[0007] The components include a tilting worktable, two three-jaw chucks, multiple locating pins, two pistons, a locating mandrel, a locating block, and locating screws.

[0008] The two three-jaw chucks are symmetrically mounted on the surface of the tilting worktable;

[0009] The two pistons are respectively disposed above the two three-jaw chucks, and the plurality of positioning pins are respectively disposed between the two three-jaw chucks and the two pistons;

[0010] The positioning mandrel is pluggable and insertable into the interior of the piston;

[0011] The positioning block is mounted on the surface of the three-jaw chuck;

[0012] The positioning screw is installed on the positioning block.

[0013] Preferably, the three-jaw chuck is used for mounting the piston.

[0014] Preferably, the positioning screw is used to limit the positioning mandrel.

[0015] Preferably, a disassembly assembly is provided between the flipping worktable and the three-jaw chuck. The disassembly assembly includes a U-shaped mounting slot, a threaded rod, and a threaded sleeve. The threaded rod is installed at the bottom of the three-jaw chuck, and the threaded sleeve is threadedly connected to the surface of the threaded rod.

[0016] Preferably, the U-shaped mounting slot is formed on the surface of the flipping worktable.

[0017] Preferably, the threaded rod and the threaded sleeve are used for the installation and removal of the three-jaw chuck.

[0018] Compared with related technologies, the automatic alignment dual-station multi-angle drilling and boring fixture for steel pistons provided by this utility model has the following advantages:

[0019] This utility model provides a steel piston automatic alignment dual-station multi-angle drilling and boring fixture. Two three-jaw chucks, multiple positioning pins, two pistons, a positioning mandrel, a positioning block, and positioning screws are respectively set on the flipping worktable. It effectively avoids the machining position deviation caused by manual clamping, greatly improves the positional accuracy of steel piston machining, and can better meet the high precision requirements of steel pistons for equipment such as engines, thereby improving the product quality of steel pistons.

[0020] Improving work efficiency: This fixture is equipped with a flip-up worktable, enabling one machine to complete multi-angle processing.

[0036] First Embodiment

[0037] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, Figure 6 , Figure 7 and Figure 8 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of a steel piston automatic alignment dual-station multi-angle drilling and boring fixture provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the three-dimensional structure of the rotating worktable shown; Figure 3 for Figure 1 A schematic diagram of the three-jaw chuck structure shown; Figure 4 for Figure 1 A three-dimensional structural diagram of the locating pin is shown; Figure 5 for Figure 1 A schematic diagram of the three-dimensional structure of the piston shown; Figure 6 for Figure 1 A schematic diagram of the three-dimensional structure of the positioning mandrel shown; Figure 7 for Figure 1 A schematic diagram of the three-dimensional structure of the positioning block shown; Figure 8 for Figure 1 The diagram shows a three-dimensional structure of the positioning screw. A steel piston automatic alignment dual-station multi-angle drilling and boring fixture includes:

[0038] 1. Flip-top worktable; 2. Two three-jaw chucks; 3. Multiple positioning pins; 4. Two pistons; 5. Positioning mandrel; 6. Positioning block; 7. Positioning screw;

[0039] The two three-jaw chucks 2 are symmetrically mounted on the surface of the tilting worktable 1;

[0040] The two pistons 4 are respectively disposed above the two three-jaw chucks 3, and the plurality of positioning pins 3 are respectively disposed between the two three-jaw chucks 2 and the two pistons 4;

[0041] The positioning core rod 5 is plugged into and connected to the inside of the piston 4;

[0042] The positioning block 6 is mounted on the surface of the three-jaw chuck 2;

[0043] The positioning screw 7 is installed on the positioning block 6.

[0044] The three-jaw chuck 2 is used for mounting the piston 4.

[0045] The positioning screw 7 is used to limit the positioning mandrel 5.

[0046] The first station is the drilling process. The piston 4 is placed on the three-jaw chuck 2, and the positioning mandrel 5 is inserted into the pin hole of the piston 4. The piston 4 is roughly positioned by the positioning screw 7 assembly. Then the piston 4 is clamped by the three-jaw chuck 2, and the positioning mandrel 5 is pulled out. During operation, the probe installed on the machining center is used to accurately center the inner cavity of the piston 4. Then the straight oil hole is drilled. After the worktable 1 is rotated at a certain angle, the angled oil hole is drilled.

[0047] The second station is the boring process. The positioning pin 3 is installed on the three-jaw chuck 2. During operation, the piston 4 with the straight hole is placed on the positioning pin 3. The piston 4 is clamped by the three-jaw self-centering chuck. After the worktable 1 is rotated 90°, the piston pin hole is bored.

[0048] The entire device enables one machine to complete multi-angle processing. At the same time, it adopts a Renishaw probe and a three-coordinate measuring machine to correct the workpiece position (avoiding the positional deviation caused by manual clamping) to ensure positional accuracy. The previous process was divided into four steps: drilling straight holes, boring holes, drilling angled oil holes 1 and drilling angled oil holes 2, which required two machines and two people. Because the angled oil holes are at two angles, the improved device allows one machine to complete two steps with one person and one set of tooling.
