The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is advanced to describe in detail:
As Fig. 1, shown in Figure 2, the cam driving gear of a kind of ingot blank surface uniform deposition, it is characterized in that comprising countershaft 1, first connecting rod 2, cam follower 3, cam 4, motor 5, casing 6, nozzle driving 7, nozzle 71, second connecting rod 8, connect motor 5 on the cam 4, cam 4 is connected with an end of cam follower 3, the other end of cam follower 3 is connected with an end axle of first connecting rod 2, the other end of first connecting rod 2 is connected with an end axle of countershaft 1, the other end of countershaft 1 is connected with second connecting rod 8, connect nozzle driving 7 on the second connecting rod 8, nozzle 71 is set on the nozzle driving 7, and nozzle driving 7 is arranged on a side of casing 6.
As shown in Figure 2, second connecting rod 8 of the present utility model takes the shape of the letter U, and two ends of U-shaped are connected with countershaft 1, nozzle driving 7 respectively.
As shown in Figure 2, nozzle driving 7 of the present utility model comprises nozzle 71, drive link 72, fixture 73, place drive link 72 on the nozzle 71, the end of drive link 72 is connected with casing 6 by fixture 73 respectively, and the drive link 72 between nozzle 71, fixture 73 is connected with a wherein end of U-shaped second connecting rod 8.
As shown in Figure 1, motor 5 of the present utility model drives cam 4 and at the uniform velocity rotates, and cam 4 drives cam follower 3 and does toward the complex line swing according to set rule, adopts the roller contact between cam 4 and the driven member cam follower 3, so that reduce friction, the radius of roller is selected according to stressed concrete condition.The first connecting rod 2 that cam follower 3 drives contact is with it done oscillating motion.Be interference fit between first connecting rod 2 and the countershaft 1, so countershaft 1 rotates with first connecting rod 2.As shown in Figure 2, rotatablely moving of countershaft 1 makes second connecting rod 8 do the reciprocal translation of above-below direction.Thereby make drive link 72 do and identical the rotatablely moving of countershaft 1 characteristics of motion, drive nozzle 71 swing repeatedly in the certain angle scope.
Because in the unit interval, the deposited material flow that sprays in the nozzle equates, for making ingot blank surface uniform deposition, equates as long as guarantee the annulus area of atomizer (atomizing) cone unit interval interscan.The blank upper surface that forms in the Models of Spray Deposition is as shown in Figure 3 got sectorial area o-a-b, and it is an atomizer in the edge of blank upper surface moves to a bit of time the process of axis, the zone that the atomization metal drop is deposited on the deposition blank.
Suppose that metal drop is dA in the zone that dt deposited in the time, total sediment quality is dV, can obtain following formula:
In time period, depositor is the uniform speed rotation at dt, and its angle that turns over is ∠ aob,, suppose that the molten drop uniform deposition is on the depositor of rotation, then:
dV＝dA·h≈R·β·dR·h
In the formula, h represents deposit thickness, and β represents the angle of ∠ aob, and R represents the radius of this deposition region, and dR is a scanning area at radially width.
In the identical time, deposition is identical, and the simultaneous formula can obtain following formula:
In the formula, what dR/dt represented is the translation scan speed v of atomizer.
It is generally acknowledged that metal quality flow rate φ v is constant, when the rotary speed of depositor was uniform motion, anglec of rotation β in the unit interval and deposit thickness h were constants.Therefore, the translation scan speed v of atomizer, it and radius R are inversely proportional in theory.
According to the motion carry-over factor of whole system, can obtain the movement velocity of cam follower 3 and the relation between the surface sweeping radius R, thereby derive the theoretical contour of cam.
Do uniform rotation by the Motor Drive cam, the cam driven driven member is done toward the complex line swing according to set rule, adopts the roller contact between cam and the driven member, reduces friction.In whole system, by each axle and connecting rod transmission campaign, thereby realize the mode of nozzle with the assurance uniform deposition, in the scope that becomes 0 to 90 degree angle with vertical direction, do oscillating traverse motion.
