Description of drawings
Fig. 1 is the schematic block diagram of steps flow chart of the manufacture method of door module of integral vehicle main model checking fixture of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
Fig. 1 is the schematic block diagram of steps flow chart of the manufacture method of door module of integral vehicle main model checking fixture of the present invention.
With reference to Fig. 1, the manufacture method of door module of integral vehicle main model checking fixture of the present invention mainly comprises following step:
Step a: the aluminium alloy blank is carried out roughing, form the rough-wrought product of the workpiece that forms door module of integral vehicle main model checking fixture, and the rough-wrought product of above-mentioned workpiece is carried out Ageing Treatment.So-called roughing is exactly on the basis that keeps certain allowance, process according in advance the design primary structure with workpiece on the aluminium alloy blank with the CNC machining center in advance, and process accordingly need in the subsequent step be used for the location, support, the platform structure of lifting, what need explanation here is for the location, support, the platform structure of lifting is not exist at final product, but only be for the follow-up easy to process and intermediate structure of design, removal that can be in good time in follow-up procedure of processing.
As preferred version, the workpiece of the composition door module of integral vehicle main model checking fixture in of the present invention comprises door skin and car internal hilar plate.Below do not have specified otherwise, the workpiece of indication all describes as embodiment with door skin and car internal hilar plate.
In addition, below to the processing of workpiece, refer to use the CNC machining center to the processing that hockets of the tow sides of workpiece.
As a kind of preferred version, roughing and Ageing Treatment among the step a hocket at twice, carry out for the first time double-edged roughing, 5 millimeters surpluses are respectively stayed on the two sides, then carried out natural aging treatment 168 hours, carry out the double-edged roughing second time after the natural aging treatment, 3 millimeters surpluses are respectively stayed on the two sides, then carry out artificial aging and process; Carry out in the roughing at the tow sides to the aluminium alloy blank, tow sides are all reserved the position of machining benchmark platform, and in addition, the locating platform that is used for lifting and support also will be reserved.Described machining benchmark platform refers to the platform for the lathe tool processing dead-center position of determining the CNC machining center, and described locating platform is for the follow-up man-hour that adds, in order not affect the structure of workpiece itself, some is suitable for the sufficient platform structure of surplus that stressed part processes at workpiece.
Artificial aging among the step a adopts following technical scheme: be that insulation was placed 6-10 hour in 180 degrees centigrade of (± 5 degrees centigrade) aging furnaces in temperature.
Step b: at the corresponding machining benchmark platform of rough-wrought product trimming of workpiece.Because during the artificial aging in step a is processed, because the stress that roughing produces obtains discharging, and then processing deformation makes moderate progress, and the machining benchmark platform of processing among the step a may change, and therefore needs the corresponding machining benchmark platform of trimming.
Step c: the rough-wrought product to workpiece carries out semifinishing, and the controlled working amount keeps certain allowance, forms the semifinishing product of workpiece.So-called semifinishing refers to further reduce allowance on rough machined basis, still keeps such as intermediate structures such as locating platforms simultaneously.
As a kind of preferred version, in carrying out step c during semifinishing, be used for lifting and the locating platform that supports continues to keep, control the processing capacity of every cutter during processing, tow sides all keep 1 millimeter surplus.
Steps d: the semifinishing product to workpiece carries out Ageing Treatment.
As a kind of preferred version, the Ageing Treatment in the steps d is the natrual ageing in thermostatic chamber, and the time of natrual ageing is 72 hours, and the temperature range of thermostatic chamber temperature is 20 to 25 degrees centigrade, and as a kind of preferred version, temperature can be selected 22 degrees centigrade.
Step e: the semifinishing product to workpiece carries out the intensely processed products that fine finishining forms workpiece, and keeps certain allowance.
As preferred version, in step e, carry out first the front machining benchmark platform finishing of fine finishining, remove again the locating platform for lifting and support, carry out fine finishining, remove the machining benchmark platform when carrying out fine finishining machining benchmark is transformed on the measuring basis hole that workpiece itself is designed with, the controlled working amount finally keeps 0.3 millimeter surplus.
Herein, why carry out again the machining benchmark platform is revised, its reason as hereinbefore, step has namely been carried out Ageing Treatment, variation has occured in the machining benchmark platform, in order to guarantee the accurately machined precision among the step e, so repair again the machining benchmark platform.
Step f: profile and machining benchmark platform to the intensely processed products of workpiece utilize three coordinate measuring machine (Coordinate Measuring Machining is abbreviated as CMM) to measure.
Step g: according to the concrete condition of the measurement result among the step f, carry out secondary fine processing, profile is met the requirements, form the workpiece of required composition door module of integral vehicle main model checking fixture.
Allowance and intermediate structure are namely no longer preserved in so-called secondary fine processing, directly are machined to profile according to designing requirement.
In step g, if it is even to detect surplus among the step f, then the wherein one side of the semifinishing product of workpiece is carried out being refined to desired profile second time, no longer keep surplus and be used for lifting and the locating platform of support; For adding, reverse side still has the part that can support or lift man-hour, replace locating platform at the above-mentioned original position adhering resin material that has been removed for lifting and the locating platform that supports, the resin material of bonding is processed made it identical with the machining benchmark level.If it is inhomogeneous to detect surplus among the step f, then according to concrete error condition, 0.3 millimeter the surplus biasing allowance that utilizes reverse side to reserve carries out adequate compensation, carries out secondary fine processing again.
After finishing final secondary fine processing, remove the resin material that replaces locating platform, finish workpiece and finally process, form final products.The door skin and the inner plate of car door that namely meet as previously mentioned precision and hardness requirement.
Step h: assemble the workpiece of above-mentioned composition door module of integral vehicle main model checking fixture, form door module of integral vehicle main model checking fixture.
The workpiece that is about to final molding in the step g is assembled into whole car owner's model cubing door module, particularly exactly door skin and inner plate of car door is assembled into unified door module of integral vehicle main model checking fixture with regard to aforesaid preferred version, finishes whole manufacture process.
In addition, as preferred version, the material that the aluminium alloy blank uses is that the material that workpiece uses is 6 series alloys materials.6 series alloys material tensile strengths can reach 265 MPas (Mpa), and the aluminium alloy tensile strength of before technique use only has 205 MPas (Mpa).
Above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
