(with reference to Figure 11: with the inner face face in opposite directions of antetheca 3a) goes up and slides on the surface of the track sheet 36a that the rotation roller 58 of rotation roller unit 56 extends below the downside linear guides 36 that roughly is from T word shape to the cross section of antetheca 3a of being fixed in protection baffle plate 3.On this basis, main door 40 becomes the state of lower end side and a pair of rotation roller unit 56 buckles.The lower end side that can prevent main door 40 thus rearward breaks away from and swings from the inner face of antetheca 3a.
The right part of the roller supporting slice 51 of rotation roller unit 50 (ends of secondary door 60 sides) rearward is bent into approximate right angle with Rack, and the piece spare of fixing rubber system at the outer surface of this dogleg section is a retainer 85.The piece spare of also fixing rubber system on the right part (ends of secondary door 60 sides) of the supporting slice 55 of being located at main door 40 bottoms is a retainer 86.This a pair of retainer 85,86 is conflicted respectively opening main door 40 o'clock and the retainer that is separately fixed at right side wall 3b inner face 28,29 (with reference to a Fig. 3) that conflict.Can limit the amplitude of opening of main door 40 by the thickness of regulating this retainer 85,86.Can limit the anglec of rotation of secondary door 60 thus.The restriction of the anglec of rotation of this pair door 60 is seen below and is stated.
The following describes the structure of secondary door 60.As Fig. 4, shown in Figure 5, secondary door 60 promptly connects at ends of connection end 42 opposition sides of main door 40 and has the front on the end 62 and see the brace 69 (with reference to Fig. 5) that is the lengthwise band shape.A pair of up and down folding 25,25 connects the surface of secondary door 60 rear sides of being connected in of brace 69 and the back side that is connected end 62 of main door 40 rear sides.Thus, an end of connection end 62 opposition sides of secondary door 60 is promptly swum end 61 sides and can be rotated relative to main door 40.Because the connection end 42 of main door 40 is connected sheet 69 with the gap that is connected end 62 of secondary door 60 and blocks, can prevent that therefore the spittle that cuts powder and cutting fluid from spilling from this gap to the outside of protection baffle plate 3.Fig. 4, folding 25 shown in Figure 5 are equivalent to " hinge ".
The following describes the shape of guide groove 81.As shown in Figure 6, guide groove 81 is arranged on the groove on the guide plate 80, has the roughly circular-arc global shape that will protect the center side of baffle plate 3 as the inboard.Specifically, this guide groove 81 has three positions, comprising: be formed on the line part 82 of the linearity of peristome 10 (left side wall 3c) top side in opposite directions, be formed on right side wall 3b in opposite directions end side and have the curve part 84 of parabola part shape and with the connecting portion 83 that is connected with circular arc roughly between described line part 82 and the curve part 84.
The following describes the shape at each position of guide groove 81.Curve part 84 has occupied the major part from the central authorities of guide groove 81 to terminal, has the curve shape of guiding buckle axle 66, can make the angular speed of secondary door 60 rotations keep certain when main door 40 moves with certain speed.Thus, because of the angular speed of secondary door 60 can sharply not change, cause breakage etc. so buckle axle 66 and support 65 are applied load can prevent that buckle axle 66 is by curve part 84 time.
The following describes the computational methods of curve part 84 shapes.Guide groove 81 is grooves that the buckle axle 66 of the secondary door 60 of guiding passes through.Guide groove 81 is inconsistent because of the path (track) that the difference of the size of support 65, shape etc. can make the top of trip end 61 pass through.For this reason, at first when making main door 40 mobile in a certain direction with certain speed (V), calculate the track of the trip end 61 of the secondary door 60 when making secondary door 60 rotations with certain angular speed.Then, the track of the buckle axle 66 when move the trip end 61 that the track that obtains is thus obtained secondary door 60, the shape that the track shown in the formula that obtains thus is decided to be curve part 84 gets final product.
The track computational methods of the trip end 61 of at first explanation pair door 60.As shown in Figure 7, the initial point P in the curve interval that trip end 61 is begun to rotate is as initial point.Secondly, with the moving direction of the connection end 62 of secondary door 60 when this P rotates as X-axis, will by this P and with the direction of X-axis quadrature as Y-axis.To lead door again and 40 move once required haul distance as L (mm), with the left and right directions width of secondary door 60 as R (mm).Then, the angles that described X-axis and secondary door 60 are formed are as θ, and as V, the time that elapsed time t, one week of constant speed circular motion is required is as period T with the translational speed of main door 40.From these parameters, can obtain swimming the following formula of the coordinate (X, Y) of end 61.
X＝Vt+Rcosθ-R
=Vt+R (cos θ-1) ... formula (1)
Y=Rsin θ ... formula (2)
Secondly, because of θ=π t/2T, so if with its substitution formula (1), (2), then:
X=Vt+R (cos (π t/2T)-1) ... formula (3)
Y=Rsin (π t/2T) ... formula (4)
And formula (4) becomes:
π t/2T=sin
-1(Y/R) ... formula (5)
And formula (5) becomes:
T=(2T/ π) sin
-1(Y/R) ... formula (6)
Therefore, if with this formula (6) substitution formula (3), then:
X=V (2T/ π) sin
-1(Y/R)+R (cosS (sin
-1(Y/R))-1) ... formula (7)
At this moment, if further put formula (7) in order, then:
And, because of:
TV=L ... formula (9)
So if with this formula (9) substitution formula (8), then:
This formula (10) becomes the formula of track of the trip end 61 of vice door 60.
The following describes the track computational methods of the buckle axle 66 of secondary door 60.The track of buckle axle 66 changes because of the difference of the length of the 1st supporting slice 65a of the width R of the haul distance L of main door 40, secondary door 60, support 65 etc.For this reason, in the present embodiment, as shown in Figure 7, be set at L=680mm, R=281mm, the geometric locus of buckle axle 66 is obtained the set of this curve when drawing track by being obtained by formula (10) of the trip end 61 of secondary door 60 according to the general approximate expression analysis program of least square method.Followingly show the approximate expression of obtaining according to the approximate expression analysis program as an example.
y＝-0.0007324x
2+1.438x-10.94
Can form curve part 84 along the track that obtains by this formula (11).
Adopt above method to calculate the shape of curve part 84.Like this, when buckle axle 66 when this curve part 84 slides, rotate along the track of being obtained by formula (10) the trip end 61 of secondary door 60.Thus, when main door 40 moves with certain speed, secondary door 60 is folded lentamente on one side with certain angular speed rotation.
With the predetermined distance (for example 140mm) of ordering to B from the A point that passes through as buckle axle 66 between secondary door 60 linearity sectors that move.To become 90 the position C points of buckle axle 66 when spending as the B point that passes through from buckle axle 66 to the anglec of rotation of pair 60 between the Rotary Districts of secondary door 60 rotations.This occasion, B point are exactly the flex point of track of the buckle axle 66 in the track of the buckle axle 66 between the linearity sector and curve interval.If buckle axle 66 is the B point with original form by this flex point, then the action meeting of secondary door 60 is varied to spinning movement suddenly from the straight line shift action.This occasion is because of having applied load to buckle axle 66 and support 65, so tend to cause the breakage of buckle axle 66 and support 65.For this reason, as shown in Figure 6,, can make buckle axle 66 from the curve interval of smoothly dividing a word with a hyphen at the end of a line between linearity sector shown in Figure 7 by being that B point place is provided with the connecting portion 83 that is connected by level and smooth circular arc in flex point.Can alleviate the load that buckle axle 66 and support 65 are applied thus.As mentioned above, because guide groove 81 is made of line part 82, connecting portion 83, curve part 84, therefore can makes secondary door 60 be driven in moving of main door 40 and smoothly rotate.
The on-off action of the gate cell 20 of said structure is described below with reference to Fig. 8～Figure 15.At first as shown in Figure 8, by gate cell 20 with peristome 10 closing state under, main door 40 and secondary door 60 (with reference to Figure 13) in the same plane.Like this, main 40 faces of forming with secondary door 60 are closed peristome 10 fully.As shown in figure 13, the buckle axle 66 of secondary door 60 is positioned at the top (some A position shown in Figure 6) of line part 82 of the guide groove 81 of guide plate 80.
Then, during layback, the rotation roller unit 50 of main door 40 shown in Figure 11 slides on upside linear guides 35 door handle 41 of holding main door 40, rotates roller unit 56,56 and slides on the track sheet 36a of downside linear guides 36 to the right.Thus, move along peristome 10 because of main 40, so as shown in Figure 9, peristome 10 is slowly opened.Secondary door 60 has been subjected to main door 40 application of forces towards right side wall 3b side by folding 25.Like this, because of the line part 82 of secondary 60 buckle axle 66, so secondary door 60 moves with main 40 by guide groove 81 shown in Figure 6.
And, when beginning behind the line part 82 of buckle axle 66 by guide groove 81, the inboard that the top of the trip end 61 of secondary door 60 pulls to protection baffle plate 3 is formed biasing by support 65 by circular-arc connecting portion 83.Thus, secondary door 60 is from the spinning movement of dividing a word with a hyphen at the end of a line smoothly of straight line shift action.As shown in figure 14, if make buckle axle 66 by passing through curve part 84 behind the connecting portion 83 of guide groove 81 again, then secondary door 60 is kept former state ground with certain angular speed and is continued to rotate.Like this, certain because of the angular speed of secondary door 60, so the action of secondary door 60 can not change suddenly, can not apply load to buckle axle 66 and support 65.And, owing to 84 are mild bendings, so, use certain power to move it even firmly main 40 of pulling of operator can not feel that door handle 41 is heavy yet from connecting portion 83 to curve part.Burden in the time of can alleviating operator's actuating doors unit 20 thus.
Along with buckle axle 66 to the moving of curve part 84 end side of guide groove 81, main door 40 diminishes gradually with the angles that secondary door 60 forms.In case buckle axle 66, then is fixed on seat 28,29 conflicts of conflicting of retainer 85,86 and the retainer on the right side wall 3b that is fixed on protection baffle plate 3 on the connection end 42 of main door 40 near the terminal of guide groove 81.Like this, the rotation of secondary door 60 stops, and moving of main door 40 also stops simultaneously.This moment, main door 40 was limited in not being in the following degree of 90 degree with the angle that secondary door 60 forms.
The following describes the reason of the angle of restriction master door 40 and secondary door 60 formation.As mentioned above, retainer 85,86 and retainer conflict seat 28,29 is used to regulate main 40 angles that form with pair door 60.When omitting these members, main door 40 is pushed pair door 60 to right side wall 3b side with bigger power.Can make main door 40 littler thus, and can cause the phenomenon that buckle axle 66 moves back to the rear flank, top slightly from the terminal of guide groove 81 with the angle that secondary door 60 forms.This occasion for example when the operator pulls at main door 40, because of buckle axle 66 is oppositely return suddenly in the terminal of guide groove 81, applies load and causes the reason of breakage etc. buckle axle 66 and support 65 so might become.In the present embodiment, the anglec of rotation of the secondary door 60 of seat 28,29 restrictions because retainer 85,86 and retainer are conflicted, therefore, main door 40 can not be in below 90 degree with the angle that secondary door 60 forms, and can prevent to produce the phenomenon that retreats of buckle axle 66.
Like this, as Figure 10, Figure 12, shown in Figure 15,, then expose the inboard of protecting baffle plate 3 if peristome 10 is opened fully.When the peristome 10 that will open is closed, door handle 41 by main door 40 dominated by hand is layback left, then main door 40 moves to the left, secondary door 60 turns back on the same plane with main door 40 on one side with certain angular speed rotation on one side, thereby peristome 10 can be closed fully (with reference to Fig. 8, Figure 11, Figure 13) by a main door 40 and secondary door 60 gate cells that constitute 20.
As mentioned above, the machining center 1 of present embodiment sets gate cell 20 at the peristome 10 of the antetheca 3a of protection baffle plate 3.The main door 40 that this gate cell 20 is moved by straight line and is connected and is driven in the pair 60 that main door 40 rotates an Edge Bend on one side rotationally with this master door 40 and constitute.Secondary door 60 is equipped with buckle axle 66 on the top of trip end 61 by support 65, and this buckle axle 66 slides along the guide groove 81 of the guide plate 80 of being located at protection baffle plate 3 upper surfaces.Can make secondary door 60 carry out level and smooth spinning movement thus.And the guide groove 81 of present embodiment is made of the line part 82 of linearity, circular-arc connecting portion 83 and curve part 84 with parabola part shape.
Lathe of the present invention is not limited to the foregoing description, can carry out various distortion certainly.For example, in the foregoing description, gate cell 20 has adopted when the front is seen master's door 40 to be configured in the left side and secondary door 60 is configured in the structure on right side, but also can adopt main door 40 to be configured in the structure that right side, secondary door 60 are configured in the left side.This occasion pulls to left with main door 40 and moves it the secondary door 60 folding structure of sidewall 3c side left thereby become.
In the foregoing description, constitute by rotation roller unit 50,56, upside linear guides 35 and downside linear guides 36 as the moving structure of main door 40, but the also structure beyond the said structure, the also structure that it is slided in orbit.
In the foregoing description; adopt retainer conflict 28,29 structure of conflicting that make the retainer 85,86 of being located at main 40 side and be located at the right side wall 3b inner face of protection baffle plate 3, but also can adopt the structure that retainer 85,86 inner faces direct and right side wall 3b are conflicted.Also retainer 85,86 can be arranged on the inner face of right side wall 3b.
In the foregoing description, support 65 is made of the 1st supporting slice 65a and the 2nd supporting slice 65b, but also can only be made of the 1st supporting slice 65a, buckle axle 66 is arranged on the leading section of the 1st supporting slice 65a.
