A kind of column and knee type CNC milling machine with manual locking device
Technical field
This utility model relates to a kind of numerical control milling machine device, a kind of column and knee type CNC milling machine with manual locking device.
Background technology
Milling machine refers mainly to the lathe using milling cutter to process kinds of surface on workpiece, generally milling cutter rotary motion is main motion, workpiece (with) movement of milling cutter is feed motion, milling machine can process plane, groove, various curved surface, gear etc. can also be processed, can also process more complicated profile, efficiency relatively planer is high, is used widely in machine-building and repairing department.Along with the development of science and technology, people investigated CNC milling machine, uses the work process of program-control milling machine, and milling machine can be divided into column and knee type milling machine, the desk-top milling machine of planer-type milling machine, not lifting work, watchmaker's milling machine etc..Column and knee type CNC milling machine is a kind of milling machine that people commonly use, but although existing column and knee type CNC milling machine meets the use demand of people, but the column and knee type of lathe is suspended on bed piece and before and after support works platform and side-to-side movement, cause lifting platform rigidity not enough, fluctuation of service, this will affect the precision in the course of processing.
Summary of the invention
The purpose of this utility model is to provide a kind of column and knee type CNC milling machine with manual locking device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of column and knee type CNC milling machine with manual locking device, including base, lifting platform, manual locking device and lathe bed, described base is positioned at bottom, lathe bed is arranged on the upper end of base, lifting platform is arranged on before lathe bed by slide rail and slide block, lifting platform both sides are mounted on manual locking device, and lathe bed is provided with digital control system, servomotor, main shaft and roller bearing screw mandrel.
As further program of the utility model: be provided with main spindle box outside main shaft, servomotor is arranged on the support on lathe bed top by fixed plate.
As further program of the utility model: the upper end of lifting platform is provided with workbench and cutter.
Compared with prior art, the beneficial effects of the utility model are: this device is reasonable in design, failure rate is low, safety in utilization and good operation stability;Detachability is good, it is simple to installing and operational maintenance, the lifting platform both sides of this device are provided with manual locking device, can ensure that the rigidity of lifting platform so that lifting platform operates steadily in lifting process, it is ensured that the machining accuracy of the course of processing, ensure the qualification rate of processing part, increase economic efficiency.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-3, a kind of column and knee type CNC milling machine with manual locking device, including base 1, lifting platform 2, manual locking device 3 and lathe bed 4, described base 1 is positioned at bottom, lathe bed 4 is arranged on the upper end of base 1, lifting platform 2 is arranged on before lathe bed 4 by slide rail and slide block, and lifting platform 2 both sides are mounted on manual locking device 3, and lathe bed 4 is provided with digital control system, servomotor, main shaft and roller bearing screw mandrel.Being provided with main spindle box outside main shaft, servomotor is arranged on the support on lathe bed 4 top by fixed plate.The upper end of lifting platform 2 is provided with workbench and cutter.
Operation principle of the present utility model is: when needing the height adjusting lifting platform 2, manually being locked by the manual locking device 3 of lifting platform 2 both sides, lifting platform 2 just can be with even running at lifting process, it is ensured that the machining accuracy of the course of processing.This device is reasonable in design, failure rate is low, safety in utilization and good operation stability;Detachability is good, it is simple to installing and operational maintenance, lifting platform 2 both sides of this device are provided with manual locking device 3, can ensure that the rigidity of lifting platform 2 so that lifting platform 2 operates steadily in lifting process, it is ensured that the machining accuracy of the course of processing, ensure the qualification rate of processing part, increase economic efficiency.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from this patent objective.
