Slidable workpiece cooling mechanism

Abstract

The invention relates to the technical field of numerically-controlled machine tool equipment, in particular to a slidable workpiece cooling mechanism. The slidable workpiece cooling mechanism comprises an air cylinder rear support fixed to a headpiece part and hinged to an air cylinder tailstock; the air cylinder tailstock is fixed to the rear end of an air cylinder, a piston rod of the air cylinder extends out of the front end and is fixed to an air cylinder connector; the air cylinder connector is provided with a first rotary shaft, and the upper ends of a first connecting rod and a second connecting rod movably penetrate through the first rotary shaft; the lower end of the second connecting rod is hinged to a second hinged seat which is fixed to the headpiece part; the lower end of the first connection rod is hinged to a first hinged seat which is fixed to a cooling pipe holder; the cooling pipe holder is provided with a universal pipe and a first guide rail; and the first guide rail is matched with a second guide rail fixed to the bottom of the headpiece part. According to the slidable workpiece cooling mechanism, mutual interference between the universal pipe and a tool changer is avoided, the tool changing efficiency and the workpiece cooling efficiency are improved, and therefore, the precision, quality and production rate of machined workpieces are guaranteed.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tool equipment, in particular to a slidable workpiece cooling mechanism. Background technique [0002] The cooling system of CNC machine tools occupies a very important position in the whole machine tool, not only for cooling, but also for lubrication. During a typical machining operation, the high-speed rotation of the spindle drives the tool to cut the workpiece, and the heat generated during this process will directly affect the accuracy and processing efficiency of the workpiece. For the heat generated during processing, the workpiece and cutting tool are cooled and lubricated mainly through the workpiece cooling mechanism. The workpiece cooling mechanism is to spray coolant from the nozzle and universal pipe into the cutting area during processing to cool the workpiece and the tool, and also to clean chips, reduce friction, and reduce tool wear, so as to ensure the workpiec...

Problems solved by technology

However, in the existing CNC machine tool equipment, the workpiece cooling mechanism is fixed. When the tool magazine is rotated for tool change, the universal pipe spraying cooling water interferes with the tool magazine, which leads to low tool change efficiency. The cooling efficiency of the workpiece is low, resulting in waste, the cooling is not timely, the heat generated by cutting deformation and internal and external friction will directly affect the accuracy, quality and productivity of the processed workpiece
