Description

Technical Field

[0001] The present invention belongs to the technical field of grinding machine processing equipment, and particularly relates to a double-station turret-type composite grinding machine. Background Art

[0002] In the field of modern mechanical processing, as a key equipment for achieving high-precision surface processing, grinding machines are widely used in industries such as aerospace, automobile manufacturing, and precision instruments. Traditional grinding machines usually adopt a single-station processing mode, and the workpiece can only perform grinding operations for a single process after a single clamping. There are many limitations in this processing method: on the one hand, the frequent processes of workpiece clamping and unclamping not only consume a large amount of time and reduce production efficiency, but also multiple clamps are likely to introduce positioning errors, affecting processing accuracy; on the other hand, single-station processing cannot meet the processing requirements of complex parts with multiple processes and multiple surfaces. For parts that require multiple grinding processes such as outer circle, inner hole, and end face, they often need to be transferred between different equipment, resulting in an extended production cycle and increased processing costs. Summary of the Invention

The clamping slide table is provided with a workpiece clamping mechanism for clamping a workpiece. Two turret mounting seats are movably arranged at the upper end of the grinding machine base, respectively located on both sides of the workpiece clamping mechanism. Turret bodies are respectively rotatably arranged on the turret mounting seats. The turret mounting seats are respectively connected with a turret movement drive mechanism capable of driving the turret mounting seats to approach or move away from the workpiece clamping mechanism.
