Abstract
The invention provides an improved auxiliary jacking mechanism for five-axis rotary machining blade profiles, which can strengthen the rigidity of large aluminum alloy blades in a process of rotary milling, greatly reduce the milling deformation of the profiles, and improve the machining quality of the blade profiles. The auxiliary jacking mechanism comprises a bottom plate and is characterized in that: both sides of the bottom plate are provided with a hinge pressing plate and a positioning block; and a spring jacking device is arranged on the bottom plate.
Description
(1) technical field
The present invention relates to the auxiliary process equipment of blade profile processing, be specially a kind of auxiliary jacking mechanism that is used for five-axis rotary machining blade profiles of improvement.
(2) background technology
Blade profile is a kind of free form surface, and general the employing clamps the blade root integral shroud during digital control processing, process with the mode that five revolutions are milled, and this method working (machining) efficiency height, precision is good, and back of the body arc high conformity in the blade has obtained using widely when the processing blade profile.But this processing mode is when the big blade of processing aluminium alloy, because the big blade blade of aluminium alloy is thinner, thinnest part only has 2mm～3mm, and because material property, the integral rigidity of blade is very poor, and five revolutions are milled owing to only clamped two ends, the blade middle part is hanging shape, therefore be easy to produce the milling distortion when the processing profile, blade also is easy to shake, and machined surface is easy to stay obvious chatter mark.Therefore in order to obtain preferable quality, can only reduce cutting output and tool feeding amount, eliminate the influence that the blade rigid deficiency is brought to processing, but this can have a strong impact on the milling efficiency of blade simultaneously again with this.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of auxiliary jacking mechanism that is used for five-axis rotary machining blade profiles of improvement, it can effectively add the big blade of strength aluminum alloy and mill rigidity in the process in revolution, significantly reduces profile milling distortion, promotes the blade profile crudy.
Its technical scheme is such, and it comprises base plate, it is characterized in that: described base plate both sides are equipped with hinge pressing plate and locating piece, and the spring top clamping device is installed on the described base plate.
It is further characterized in that: described base plate both sides all have the horizontal slip groove; Described hinge pressing plate and locating piece are installed in the described horizontal slip groove; Described spring top clamping device is provided with a plurality of; Described spring top clamping device is fixed in the screw of described base plate by screw; In the described spring top clamping device push rod is installed; Be embedded with spring between described push rod bottom and the described spring top clamping device; Described push rod holds out against screw by the side and is fixed in described spring top clamping device; Described push rod top has screwed hole; Be equipped with in the described screwed hole and hold out against screw; Described spring top clamping device is provided with corresponding number according to the width of blade to be processed.
A kind of auxiliary jacking mechanism that is used for five-axis rotary machining blade profiles of the application of the invention, effectively reinforced blade mills rigidity in the process in revolution, make that adding the cutting output and the tool feeding amount in man-hour is increased, profile reduces process time greatly, improve working (machining) efficiency, reduced surperficial chatter mark simultaneously, promoted the blade surface quality, it is simple to operate, highly versatile.

(5) specific embodiment
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention includes base plate 6, base plate 6 both sides are equipped with hinge pressing plate 1 and locating piece 2, and spring top clamping device 3 is installed on the base plate 6.Base plate 6 both sides all have horizontal slip groove 11; Hinge pressing plate 1 and locating piece 2 are installed in the horizontal slip groove 11; Spring top clamping device 3 is provided with a plurality of; Spring top clamping device 3 is fixed in the screw 7 of base plate 6 by screw; Push rod 8 is installed in the spring top clamping device 3; Be embedded with spring 9 between push rod 8 bottoms and the spring top clamping device 3; Push rod 8 holds out against screw 5 by the side and is fixed in spring top clamping device 3; Push rod 8 tops have screwed hole 10; Install in the screwed hole 10 and hold out against screw 4; Spring top clamping device 3 is provided with corresponding number according to the width of blade to be processed.
The present invention is used for blade profile adds man-hour, at first blade pass is crossed the rotary milling fixture clamping on lathe, adjust the position of base plate 6 upper hinges pressure 1 of the present invention and locating piece 2 according to the difference of blade model, leaf with hinge pressing plate 1 and locating piece 2 clamping blades is followed, the integral shroud position, size according to the blade width is adjusted the position of spring top clamping device 3 on base plate 6, and adjust the height that holds out against screw 4 on the spring top clamping device 3, make to hold out against screw 4 and can withstand blade, tighten the side then and hold out against screw 5 and pin and hold out against screw 4.
