Description

Technical Field

[0001] This invention belongs to the technical field of grinding equipment, specifically relating to a dual-station turret composite grinding machine. Background Technology

[0002] In the field of modern machining, grinding machines, as key equipment for achieving high-precision surface finishing, are widely used in industries such as aerospace, automotive manufacturing, and precision instruments. Traditional grinding machines typically employ a single-station machining mode, where a workpiece can only undergo a single grinding operation after a single clamping. This machining method has several limitations: on the one hand, the frequent workpiece clamping and unclamping processes not only consume a lot of time and reduce production efficiency, but also easily introduce positioning errors after multiple clampings, affecting machining accuracy; on the other hand, single-station machining cannot meet the machining needs of complex parts with multiple processes and multiple surfaces. For parts requiring multiple grinding processes such as external diameters, internal holes, and end faces, they often need to be transferred between different machines, leading to extended production cycles and increased machining costs. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a dual-station turret-type composite grinding machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A dual-station turret-type composite grinding machine includes a clamping slide movably mounted on the upper end of the grinding machine base via a reciprocating drive structure. The clamping slide has a workpiece clamping mechanism for clamping workpieces. Two turret mounting seats are movably mounted on the upper end of the grinding machine base, respectively located on both sides of the workpiece clamping mechanism. A turret body is rotatably mounted on each turret mounting seat. Each turret mounting seat is connected to a turret movement drive mechanism that drives the turret mounting seats toward or away from the workpiece clamping mechanism. A grinding wheel assembly and a detection assembly are provided on the outer side of each turret body. The turret mounting seats facilitate the installation of the turret body. The integration of the grinding wheel assembly and the detection assembly on the turret body facilitates workpiece detection and processing, improving workpiece processing efficiency. The presence of turret bodies on both sides of the workpiece further enhances processing efficiency. The cooperation between the detection assembly and the grinding wheel assembly ensures processing effectiveness. Furthermore, the turret movement drive mechanism facilitates adjustment of the turret body position, making workpiece replacement easier and improving workpiece processing efficiency.

[0005] In the aforementioned dual-station turret-type composite grinding machine, a grinding machine mounting base is provided on the upper end of the grinding machine base. Turret mounting frames are respectively provided on both sides of the grinding machine mounting base.
