Description

A kind of common metal CNC machine installing high-speed main spindle additional
Technical field
The utility model relates to CNC technical fields of mechanical processing, and in particular to for a kind of common gold for installing high-speed main spindle additional Belong to CNC machine.
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.
Utility model content
The purpose of the utility model is to provide a kind of common metal CNC machine for installing high-speed main spindle additional, main purpose is High-speed main spindle is installed additional using common metal CNC machine, further increases processing yield in the case where guaranteeing higher processing efficiency, and will not It is related to biggish cost input, so that four side hole locations for processing plastic appearance member or plastic metal composite members are solved, 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, using superelevation Fast metal CNC machines the technical problem high there are input cost.
To achieve the goals above, technical solution adopted in the utility model 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.
