In supporting arm 82, be provided with the connecting rod 85 with preceding side control disc 71 one, this connecting rod 85 is bearing on the link supporting axle 86 in the mode that can freely rotate, and this link supporting axle 86 is fixed on the supporting arm 82.Link supporting axle 86 and above-mentioned rotary middle spindle O1 be positioned at coaxial on.When overlooking, connecting rod 85 operating surface 76 1 sides of side control disc 71 forward extends, and is provided with cam bolster 87 on the leading section of connecting rod 85.Cam bolster 87 runs through circular-arc hole 88 on the base plate 82a that is formed on supporting arm 82, and extends to the below of supporting arm 82 always.Circular-arc hole 88 is to be the circular-arc hole at center with link supporting axle 86, when connecting rod 85 when link supporting axle 86 rotates, cam bolster 87 can move freely in circular-arc hole 88.And, be positioned at supporting arm 82 below the bottom of cam bolster 87, the main cam follower 90 that auxiliary cam 89 is installed and constitutes by roller.Connecting rod 85 can freely change angle mutually with auxiliary cam 89, and main cam follower 90 can freely rotate with respect to cam bolster 87.

As shown in Figure 8, auxiliary cam 89 is along the flat shape of the line symmetry of the centre line L by above-mentioned cam bolster 87.In addition, auxiliary cam 89 has slotted hole 89a on above-mentioned centre line L, and the pin 91 that is located on the supporting arm 82 is fastened among this slotted hole 89a.Thus, auxiliary cam 89 can be that the center is yaw shape ground and freely rotates with pin 91, and, can move freely on the direction in the effective length scope of slotted hole 89a, in centre line L.At least when preceding side control disc 71 was in the 1st state, the auxiliary cam follower 92 that is made of roller was connected on the cam surface 89b of auxiliary cam 89.Auxiliary cam follower 92 is by can free rotation mode being bearing on the fixed pedestal 81.

Be fixed with main cam 93 on fixed pedestal 81, this main cam 93 has the cam path 93a that above-mentioned main cam follower 90 is engaged.As shown in Figure 8, the cam path 93a of main cam 93 is the curve-like that surrounds around the above-mentioned rotary middle spindle O2 except that front part.

Being formed in the cam mechanism that limits in claims by above-mentioned main cam 93 and main cam follower 90 is the C1 of main cam mechanism, constitutes the C2 of auxiliary cam mechanism by above-mentioned auxiliary cam 89 and auxiliary cam follower 92.Constitute the multiple mounted cam C of mechanism with these C1 of main cam mechanism and the C2 of auxiliary cam mechanism.The C1 of main cam mechanism is by applying predetermined restricted to preceding side control disc 71 with respect to the rotation of supporting arm 82, thus the effect of performance attitude of side control disc 71 when preceding side control disc 71 is switched to the 1st state P1 and the 2nd state P2A, P2B, before the regulation.Under the situation of present embodiment, the attitude of preceding side control disc 71 be around the preceding side control disc 71 of rotary middle spindle O1 towards.The C2 of auxiliary cam mechanism carries out smooth and easyization, certainization auxiliary of the action of the C1 of main cam mechanism.

Figure 11 is the figure of the action of side control disc 71 before the expression.When from the 1st state P1 of (A) to preceding side control disc 71 when right applies power, preceding side control disc 71 passes through (B)～(E) each process successively, to switching towards a left side the 2nd state P2A shown in (F).At this moment, preceding side control disc 71 overlook the center, its overlook that middle position moves forward and to the left and right direction move.More precisely, be depict with rotary middle spindle O2 be the center circular-arc motion track K move.In the present embodiment, the position consistency of overlooking center and rotary middle spindle O1 of preceding side control disc 71.In moving, by the effect of the C of main cam mechanism 1, the attitude of preceding side control disc 71 changes, and when mechanical face side was seen, the face direction of operating surface 76 changed attitude from the attitude parallel with left and right directions to the attitude of operating surface 76 towards the left side.

The C2 of auxiliary cam mechanism acts on as follows.Under the 1st state (A), supporting arm 82 is in neutral condition, under this state, supporting arm 82 can with rotary middle spindle O2 be the center turn right or turn left in any one party freely rotate, act on preceding side control disc 71 and having under the situation of external force, the action of supporting arm 82 is unsettled.Therefore, supporting arm 82 is applied power around the prescribed direction of rotating central shaft O2, make smooth and easyization of action and certainization of supporting arm 82 by the C2 of auxiliary cam mechanism.Preceding side control disc 71 from the 1st state P 1 under situation about switching (Figure 11) towards a left side the 2nd state P2A, supporting arm 82 is applied around rotating the power that central shaft O2 turns right.In addition, the cam surface 89b along auxiliary cam 89 moves along with auxiliary cam 92, and pin 91 moves in the slotted hole 89a of auxiliary cam 89.

Like this, change attitude by side control disc 71 before making on one side and move, the rear portion of preceding side control disc 71 always is positioned at roughly identical position, front and back.Therefore, when being in the 1st state P1, side control disc 71 closely is configured with side control disc 72 front and back, back before can making, and control panel 70 can be set compactly.Promptly, if only be side control disc 71 rotations before making, then under the narrow situation in the interval of the

control panel

71,72 of front and back, the bight of the rear side of preceding when rotated side control disc 71 may be interfered with back side control disc 72, direction moves but forwards move also to the left and right by side control disc 71 before making, and just can prevent such interference.From the 1st state P1 under situation about switching towards right the 2nd state P2B, also same as described above.The structure of this switching mechanism 80 is because simpler and easy, and the adjustment certain and action of therefore moving is easy.

On the left and right foot section 81a of fixed pedestal 81, be fixed with sensor installing component 94 respectively, on each sensor installing component 94, the attitude of side control disc 71 before being used to detect, sensor 95A, the 95B of location status be installed.

Sensor

95A, 95B for example are near switch, are installed in down on the bottom surface of above-mentioned rotating seat bearing 84 with respect to the detected body 96 of sensor 95A, 95B.Detected body 96 has two detected portion 96aA, 96aB, and when control panel 71 became towards a left side the 2nd state P2A, sensor 95A detected detected portion 96aA, sensor 95A and opens; When control panel 71 became towards the right side the 2nd state P2B, sensor 95B detected detected portion 96aB, sensor 95B and

opens.Sensor

In the present embodiment, detect attitude, the location status of preceding side control disc 71 according to the output of the

sensor

95A, 95B, electric control loop (not shown) is constituted as: when current side control disc 71 is in the 1st state P1, even left and right control part 77A, the 77B of operation back side control disc 72 can the generation effects yet; In addition, current side control disc 71 is in towards a left side during the 2nd state P2A, even the right control part 77B of operation back side control disc 72 can the generation effect yet; And, when current side control disc 71 is in towards the right side the 2nd state P2B, even the left control part 77A of operation back side control disc 72 can the generation effect yet.

Lathe with this control panel turns round after rail portion 51A, 51B are set to closed condition Q1.On-stream, by the supply and the discharge that the 3A of the Ministry of worker, 3B carry out workpiece (not shown) that add of 2 pairs of machine tool main body 1 of filler.In detail, by moving body 31 move left and right, move forward and backward that platform 32 moves forward and backward and flexible supporting mass 33 stretching motions, filler head 34 is sent into the position and is added between the 3A of the Ministry of worker, the 3B at workpiece and moves, send into the position at workpiece, be in the workpiece of clamping raw material workpiece mounting table 66 towards the filler chuck 35 of upper/lower positions; Adding the 3A of the Ministry of worker, 3B, the filler chuck 35 that is horizontal with Workpiece supply to main shaft 5.In addition, filler head 34 moves adding between the 3A of the Ministry of worker, 3B and the workpiece launching position, is adding the 3A of the Ministry of worker, 3B, and the filler chuck 35 that is horizontal receives the finished product workpiece of completion of processing from main shaft 5; At the workpiece launching position, be in towards the filler chuck 35 of upper/lower positions the finished product workpiece is placed on the finished product workpiece mounting table.In the time of in filler head 34 drops to machining area S1A, S1B, the baffle plate 42 of dividing plate 40A, 40B is open in linkage with the lifting of filler head 34 to be full-gear.

Adding the 3A of the Ministry of worker, 3B, the workpiece that is bearing on the main shaft 5 is being carried out turning processing.Specifically, workpiece is moved to the direction of feed of cutter 10 by moving forward and backward of fast headstock 6, and, by horizontally slipping of tool table 7 cutter 10 is moved to the incision direction.Add man-hour in axial both sides to workpiece, by workpiece tipper 38 make workpiece towards upset.In turning processing, owing to the baffle plate 42 of dividing

plate

40A, 40B is closed, so smear metal can not dispersed beyond machining area S1A, S1B.Turning adds the smear metal that produces man-hour and drops on the swarf conveyor 22 by smear metal discharge space 8, transports and be expelled to the outside by swarf conveyor 22.

According to the change of the kind of the workpiece that will process, processing content etc., carry out the replacing of cutter 10, the preparation works such as replacing of spindle chuck 5a.When changing cutter 10, as shown in figure 12, under the state that this processing that adds the S1A of the Ministry of worker (S1B) is stopped, the rail portion 51A (51B) that will add this side of the S1A of the Ministry of worker (S1B) places the 1st opening Q2, and, the baffle plate 42 of dividing plate 40A (40B) is placed semi-open state, from the peristome 60 that is formed between machining area S1A (S1B) and the operator's space S 2 hand is stretched in the machining area S1A (S1B), carry out the tool changing operation.When changing spindle chuck 5a, as shown in figure 13, after the running that stops lathe integral body, the rail portion 51A (51B) that will add this side of the S1A of the Ministry of worker (S1B) accordingly places the 2nd opening Q3, open dividing plate 40A (40B), S1L carries out the cartridge changing operation through the filler moving area.

Add man-hour, preceding side control disc 71 is placed the operating surface 76 1st state P1 parallel with left and right directions.Under this state, back side control disc 72 is blocked and can't see from mechanical face side by preceding side control disc 71, is difficult to control

part

77A, 77B about rear side control part 72 are operated.Therefore, work in-process can not carry out manually operated situation to adding the 3A of the Ministry of worker, 3B with making a mistake.If,, also make this operation not produce the electric control loop thereby the safety of effect owing to constituting even operate

control part

77A, 77B mistakenly from side, the left and right sides.When current side control disc 71 is in the 1st state P1, a part and rail portion 51A, the 51B of preceding side control disc 71 are overlapping on fore-and-aft direction, but because should be seldom overlapping, thereby can not hinder 53 pairs of windows that pass through

rail portion

51A, 51B to add the 3A of the Ministry of worker, 3B to carry out Visual Confirmation.

When adding operations such as the 3A of the Ministry of worker, 3B prepare, side control disc 71 before switching and before making the operating surface 76 of side control disc 71 become towards the attitude that adds this side of the Ministry of worker of carrying out operation.That is be towards a left side the 2nd state P2A to adding when the 3A of the Ministry of worker carries out operation, when being towards right the 2nd state P2B, to adding when the 3B of the Ministry of worker carries out operation.Under these the 2nd states P2A (P2B), preceding side control disc 71 departs to the left and right from the front position of rail portion 51A (51B), and, it is narrow when the visual width ratio in the left and right sides of preceding side control disc 71 is in the 1st state P1, therefore, it is big that the front space of rail portion 51A (51B) becomes, carry out easily the opening and closing operations of rail portion 51A (51B) and health enter add that Ministry of worker's space S 1 carried out to adding the operation of the 3A of the Ministry of worker, 3B.

In addition, when current side control disc 71 is in the 2nd state P2A (P2B), owing to have only and carry out adding the corresponding control part 77A of the 3A of the Ministry of worker (3B) (77B) and can operating from mechanical face side, be difficult to from the operation of mechanical face side of operation with the corresponding control part 77B of the 3B of the Ministry of worker (3A) (77A) that adds that does not carry out operation, therefore, operate

control part

77A, 77B mistakenly about not understanding.

Figure 14 is the vertical view at main position of the lathe with control panel of another embodiment of the invention.This lathe with control panel, two adds setting side by side about the 3A of the Ministry of worker, 3B, contains these Ministry of worker's space S 1 that add that add the 3A of the Ministry of worker, 3B and is covered by body cover 50.The front part that adds the 3A of the Ministry of worker, 3B of this body cover 50 is divided into and carries out rail portion 51A, the 51B that can open and close that various operations are used to adding the 3A of the Ministry of worker, 3B.

Control panel 70 is located at the place ahead of rail portion 51A, 51B.The attitude of this control panel 70 and the either party of position or both sides' state is that attitude, location status can freely switch to the 1st state P1 and the 2nd state P2A, P2B.Because the structure of its switching mechanism is identical with above-mentioned embodiment, the Therefore, omited explanation.Under the 1st state P1, the either party of left and

right rail portion

51A, 51B is in the state that controlled dish 70 blocks when mechanical face side is seen.The integral body that both can be

rail portion

51A, 51B is blocked, and also can be that only some is blocked.Under the 2nd state P2A of a left side, left rail portion 51A becomes that not controlled dish 70 blocks when mechanical front is seen, comparing with the 1st state P1 can descried state.Under the situation of present embodiment, can see that from mechanical face side left rail portion 51A's is whole.In addition, under right the 2nd state P2B, right rail portion 51B becomes that not controlled dish 70 blocks when mechanical front is seen, comparing with the 1st state P1 can descried state.Under the situation of present embodiment, can see that from mechanical face side right rail portion 51B's is whole.

Identical with aforementioned embodiments, control panel 70 from the 1st state P1 when the 2nd state P2A, P2B switch, overlook that middle position O1 forwards moves and to the left and right direction move.Thus, in change action, same position before and after the rear portion of control panel 70 always is in roughly.Therefore, when being in the 1st state P1, control panel 70 and body cover 50 closely are configured, control panel 70 can be set compactly.

Adding man-hour, making control panel 70 be in the 1st state P1 in advance.Under the 1st state P1,, therefore can prevent to add and

open rail portion

51A, 51B man-hour mistakenly because left and

right rail portion

51A, 51B are in the state that is blocked when mechanical face side is seen.

A left side is being added under the situation that the 3A of the Ministry of worker carries out operation, control panel 70 is being placed towards a left side the 2nd state P2A,, control panel 70 is being placed towards right the 2nd state P2B the right side being added under the situation that the 3B of the Ministry of worker carries out operation.Under the 2nd state P2A (P2B), because only carrying out the rail portion 51A (51B) that adds this side of the 3A of the Ministry of worker (3B) of operation can see from mechanical face side, therefore, can not open mistakenly left and right rail portion 51A, 51B, about carry out mistakenly adding the operation of the 3A of the Ministry of worker, 3B.In addition, under the 2nd state P2A (P2B), control panel 70 departs to the left and right from the front position of rail portion 51A (51B), and the visual width in the left and right sides of control panel 70 is narrow during than the 1st state P1, therefore, it is big that the space in the place ahead of rail portion 51A (51B) becomes, and is easy to carry out the opening and closing operations of rail portion 51A (51B) and health is entered add Ministry of worker's space S 1 and to adding the operation that the 3A of the Ministry of worker, 3B carry out.

In the respective embodiments described above, arrange two lathes that add the 3A of the Ministry of worker, 3B about having illustrated side by side, but the present invention is applicable to that also adding the Ministry of worker is one lathe.In addition, can also be applicable to lathe lathe in addition.
