Drilling machine for numerical control finish machining

Abstract

The invention discloses a drilling machine for numerical control finish machining, and belongs to the technical field of drilling machines. The drilling machine for numerical control finish machiningcomprises a machine shell, wherein a hydraulic cylinder is arranged in the middle of the top end of the machine shell, the output end of the hydraulic cylinder penetrates through the top wall of the machine shell and is connected with a telescopic rod, the bottom end of the telescopic rod is provided with a drilling mechanism, a zero setting mechanism is arranged on the left side of the drilling mechanism, and a supporting base is arranged in the middle of the bottom wall of the machine shell in an internally-embedded mode. According to the drilling machine, through arrangement of the zero setting mechanism, a drill bit is replaced with zero setting mechanism to abut against a workpiece drilling surface, so that the problem that drilling errors caused by excessive abutting does not occur;when in use, an input depth instruction is calculated according to a telescopic change value of the zero mechanism, accurate drilling machining is completed, the drilling efficiency effect is greatlyimproved, chippings can be collected through an arranged cover body, chippings in the cover body can be swept and collected through the arranged cleaning mechanism, the chippings in the cover body canbe swept and collected through an arranged sweeping mechanism, manual treatment is not needed, multi-angle negative pressure dust removal can be realized through an arranged fan dust removal mechanism, and raise dust chippings generated in the machining process can be removed.

Description

technical field [0001] The invention relates to the technical field of drilling machines, in particular to a drilling machine for numerical control finishing. Background technique [0002] CNC machining refers to a process method for processing parts on CNC machine tools. The process regulations of CNC machine tool processing and traditional machine tool processing are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the movement of parts and tools. It is an effective way to solve the problems of variable variety, small batch, complex shape and high precision of parts and realize high-efficiency and automatic processing. [0003] CNC lathe is one of the most widely used CNC machine tools at present. It is mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disk parts, the inner and outer conical surfaces of arbitrary cone angles, the complex rotary inner and outer...

Problems solved by technology

[0005] When the existing CNC drilling machine is drilling, in order to ensure the accuracy of the drilling depth, it is necessary to adjust the drill bit to contact the drilling surface of the workpiece, and then input the drilling depth to meet the drilling requirements. However, this operation method , it is time-consuming to control the abutment between the drill bit and the drill surface of the workpiece, and it is difficult to accurately control the position of the drill bit, and excessive abutment of the drill bit will occur, and drilling errors will occur at this time
