Description
Technical field
The present invention relates to a kind of flexibility multi-supporting, be used for the supplemental support of weak hard parts process such as blade, belong to metal cutting processing and Metal Cutting Machine Tool field of accessories.
Background technology
Blade digital control adds man-hour because himself rigidity is very poor so be easy to generate machining deformation especially, and this also is one of present blade processing reason that need adopt backward manual grinding and polishing process.In order to improve the rigidity of blade processing, people install some supplemental support to improve its rigidity below blade.But traditional auxiliary support structure generally needs artificial the adjustment, and adjustment process is time-consuming, and pretightning force changes easily in adjustment process, and the rigidity of side direction is generally all good inadequately, and therefore the effect that produces is very limited.Traditional supplemental support mechanism directly adopts the spiral marking connection mode, and this mode lateral rigidity is poor, and screw thread is all changing at the side direction of rundown process and axial dimension and rigidity.The employing that also has in addition is laterally and tightly propped, is a kind of better mode, can utilize the frictional force effect, as long as be no more than this frictional force, its axial rigidity is very high, but lateral rigidity is influenced by threaded portion.Present multiple spot formation system is answered the general motor-driven single-degree-of-freedom screw-nut bodies that adopt of the requirement of curved surface forming more, this plant automation degree height, but volume is big, the screw thread rigidity of support is low, cost is high.Along with improving constantly that the automation of blade digital control process requires, realize that the automation that blade is installed also has very important significance, press for and develop multi-point flexibly auxiliary support apparatus a kind of automation, high rigidity, compact conformation.
Summary of the invention
The objective of the invention is in order to realize a kind of flexibility multi-supporting of blade once mounting, two sides processing, the defective that has overcome common bracing or strutting arrangement poor rigidity and be difficult to adjust and move certainly automatically face processing with two fixed position lockings.This device is by being fixed on the A oil cylinder 205 on the fuel-displaced dispense font 204 and being fixed on the location that the tapered dowel of B oil cylinder 7 controls on the tailstock tool 4 is realized cradle assemblies 1, revolution action when first Working position is used for realizing realizing cradle assemblies 1 and blade in the blade cutting process, second Working position is used for then realizing that the face that changes to blade supports under the condition of not unloading lower blade, avoided changing the space restriction causes in the face process the cradle assemblies 1 and the interference problem of lathe table top.Oil-feed distributor 201 among the present invention and go out oil dispenser 202 and realized the motion of oil circuit, gas circuit and vacuum passage, the conversion of inactive state; A flexible support assembly 3 is simple in structure, and space is little, and A cylinder 308 and B cylinder 307 have all adopted the bellows-type cylinder littler than common air cylinder structure; According to the variation of different blade profile windup-degrees, can realize the support normal of blade profile by the structural change of cradle assemblies 1, guaranteed reliable and stable support normal; The structural design of the A eccentric block 333 on the A end cap 301, B eccentric block 334, C eccentric block 335, D eccentric block 336 and E eccentric block 337 has realized the high axial stiffness of support bar 305 in 301 pairs of support bar 305 clamping process of A end cap, and A flexible support assembly 3 has adopted with B flexible support assembly 6 and had two fulcrums, high side direction and axial stiffness simultaneously; The all working motion process of this flexible header system need not artificial adjustment by programme-control, the automaticity height.
