CNC machine tool

Abstract

The invention provides a numerical control machine tool. The numerical control machine tool comprises a workpiece clamping mechanism and a cutter clamping mechanism, wherein the cutter clamping mechanism comprises a positioning shaft, the positioning shaft is sleeved with a cutter disc, at least two cutter movement grooves are formed in the cutter disc, and cutters are arranged in the cutter movement grooves in a penetrating mode in the axial direction of the cutter disc; the positioning shaft is located at the center of the cutter disc, a cuter pushing mechanism used for pushing the cutters to the positioning shaft from the direction away from the positioning shaft is arranged in the cutter movement grooves, the cutter pushing mechanism is provided with a cutter locking / automatic unlocking mechanism, a cutter restoration mechanism used for pulling the cutters to be close to the outer edge of the cutter disc along the cutter movement grooves is arranged in the cutter movement grooves, and the cutter pushing mechanism is provided with a sliding guide rail mechanism and a pushing and sliding driving mechanism; a cutter capturing mechanism is arranged on the positioning shaft. The numerical control machine tool has the advantages that multiple groups of cutters are arranged in the cutter disc in a hidden mode, using is safe, actuating units used for cutter change are reasonably arranged, and cutter change is stable and smooth.

Description

technical field [0001] The invention relates to the field of machining, in particular to a numerically controlled machine tool. Background technique [0002] Existing CNC machine tools generally include a workpiece clamping mechanism and a tool clamping mechanism, the workpiece clamping mechanism is provided with a feed drive mechanism, and the tool clamping mechanism is provided with a displacement drive mechanism. The problems existing in the existing technology are: usually only one shape of tool can be clamped at a time for processing, and the tool needs to be replaced manually repeatedly when performing mechanical processing with more complex shapes, which is time-consuming and laborious; However, the tool is exposed relative to the cutter head, which poses safety risks to the equipment itself and the operator; in addition, the existing CNC lathes either have no cooling mechanism at all or the cooling mechanism is unreasonably set up, which may easily lead to overheatin...

Problems solved by technology

The problems existing in the existing technology are: usually only one shape of tool can be clamped for processing at a time, and the tool needs to be replaced manually repeatedly when performing mechanical processing with more complex shapes, which is time-consuming and laborious; However, the tool is exposed relative to the cutter head, which poses safety risks to the equipment itself and the operator; in addition, the existing CNC lathes either do not have a cooling mechanism at all or the cooling mechanism is not set properly, which may easily lead to overheating and scrapping of the workpiece; Moreover, the existing CNC lathes usually do not deal with the cutting chips, and it is easy to cause equipment failure due to the splashing of cutting chips into the joints of various functional components, which poses a great safety hazard
