Description
Technical field
The present invention relates to CNC technical fields of mechanical processing, and in particular to for a kind of common metal CNC for installing high-speed main spindle additional
Machine and its application method.
Background technique
Currently, usually there are three types of types for the consumption electronic products surface structure such as smart phone part: outside metal appearance part, plastic cement
See part and plastic metal composite members.Metal appearance part be usually it is machining by common metal CNC, plastic outer part be by
Injection molding machine injection molding, plastic metal composite members are that plate in aluminium alloy or magnesium alloy pressure-casting is passed through the injection molding of mould embedded component
's.The hole locations such as plastic outer part and key hole, the hole USB, earpiece holes, speaker hole in plastic metal composite members are usually to use
CNC is machining.
Common metal is known as the mainstream CNC type for processing the consumption electronic products metal appearance part such as smart phone
CNC machine, the maximum speed of spindle of common metal CNC machine are usually less than 24000 revs/min, and general type be all equipped with tool magazine,
Four axis workbench.Therefore, using all of common metal CNC machining four sides of plastic outer part or plastic metal composite members
Hole location only needs clamped one time that can complete the automatic processing of four all hole locations in side on a common metal CNC machine.But
It is that since the maximum speed of spindle of common metal CNC machine is relatively low, and actual processing plastic outer part or plastic metal are compound
When part, it is contemplated that vibration and dynamic balancing factor, the speed of mainshaft are normally controlled in 16000-18000 revs/min, therefore product when processing
Suffered cutting force is larger, can generate stress trace, will cause plastic cement and metal junction cracks, and can generate at hole location edge larger
Size collapses paint, to cause processing yield low.
Plastic cement CNC is known as the mainstream CNC type for processing the consumption electronic products plastic outer part such as smart phone
The maximum speed of spindle of machine, plastic cement CNC machine may be up to 60000 revs/min.Plastic outer part or modeling are machined using plastic cement CNC
Four side hole locations of glue metal composite part, the stress trace of generation is lighter, and the probability for causing plastic cement to crack with metal junction is low,
It is low in the probability that generation larger size in hole location edge collapses paint.But common plastic cement CNC machine is not equipped with tool magazine, fixture
Workbench is typically only capable to provide the translational motion of X-axis, Y-axis, cannot provide the rotary motion of X-axis.Therefore, using plastic cement CNC machine
All hole locations of four sides of processing plastic appearance member or plastic metal composite members, need for process to be split as four works
Sequence only processes the hole location of a side on a plastic cement CNC machine, retransfers under processing on workpiece to next plastic cement CNC machine
The hole location of one side, it is thus desirable to which four plastic cement CNC machines could complete a workpiece four sides by four processes
The processing of all hole locations.Due to processing one workpiece need process it is more, clamping times are more, board quantity is more, cause logistics and
Examine manpower and the time cost of consumption high, to cause that processing efficiency is low, while workpiece repeatedly shifts and multiple clamping causes
The probability of damage increases, to reduce processing yield.
And four side hole locations of ultrahigh speed metal CNC machining plastic outer part or plastic metal composite members are used, though
It so can be improved processing yield, and processing efficiency can be improved.But ultrahigh speed metal CNC machine is with respect to common metal CNC machine price
Valuableness, the input cost of great number, which is not that most enterprises are afforded, to be risen.
Therefore, how using existing common metal CNC machine come processing plastic appearance member or plastic metal composite members, and mention
Height processing yield becomes the problem of puzzlement CNC engineer.
Summary of the invention
It is main the object of the present invention is to provide a kind of common metal CNC machine and its application method for installing high-speed main spindle additional
Purpose is that it is good to further increase processing in the case where guaranteeing higher processing efficiency using common metal CNC machine installation high-speed main spindle
Rate, and will not relate to biggish cost input, to solve four for processing plastic appearance member or plastic metal composite members
Side hole location, it is low in the presence of processing yield using common metal CNC machining, using plastic cement CNC machining in the presence of processing efficiency is low,
The technical problem high there are input cost is machined using ultrahigh speed metal CNC.
To achieve the goals above, the technical solution used in the present invention is:
A kind of common metal CNC machine installing high-speed main spindle additional, including four axis workbench, the fixture, original being arranged on base
With main shaft and tool magazine, the four axis workbench is located at the lower section of first wife's main shaft, and the fixture is mounted on the four axis work
Make on platform, the tool magazine is located at the top of first wife's main shaft, and the tool magazine clamping is placed with the knife of multiple and different specifications
Have, is provided with high-speed main spindle fixed frame on first wife's main shaft, the high-speed main spindle fixed mount setting has high-speed main spindle, the folder
Tool clamps by location hole and is fixed with workpiece to be processed, and the high-speed main spindle grabs from the tool magazine and clamps the knife
Tool processes the workpiece, and the fixture that the four axis workbench driving clamps the workpiece does four axis relative to the high-speed main spindle
Movement.
Common metal CNC machine is included to be equipped with tool magazine and four axis workbench, wherein tool magazine is for clamping stand-by knife
Tool, four axis workbench provide the four axes motion relative to high-speed main spindle for fixture, only to need on a common metal CNC machine
Clamped one time workpiece can complete the automatic processing of four all hole locations in side of workpiece, improve processing efficiency.In first wife master
High-speed main spindle is installed additional using high-speed main spindle fixed frame on axis, workpiece is processed using high-speed main spindle clamping cutter, due to warp
More high-revolving processing can be carried out after installing high-speed main spindle additional, the stress trace generated is lighter, improves processing yield；Opposite purchase
The high buying expenses of ultrahigh speed metal CNC machine are bought, enterprise's lathe is also greatly reduced using the lower high-speed main spindle of price
Purchase cost.High-speed main spindle is also known as high-speed electric main shaft, the asynchronous high efficiency motor of three phase variable frequency built in high-speed main spindle, by frequency converter root
It is instructed according to encoder and carries out variable speed control.High-speed main spindle and encoder, cooling device, lubricating arrangement, are moved frequency converter certainly
The processing to workpiece is completed in knife system and cutter cooperation, these devices all can be directly commercially available on the market, such as high-speed main spindle
The product that the model DGZ-06260/1.8B1-IPWJM of Guangzhou Haozhi Electromechanical Shares Co., Ltd. can be selected, in addition, the public affairs
Department also sells the relevant auxiliary products of high-speed main spindle.
