Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ 6, comprise actuating cam 1, first arc groove 1.1, second arc groove 1.2, three-arc groove 1.3, first bearing pin 2, second bearing pin 3, plate 4, the 3rd bearing pin 5, roller 6, screw 7, first cam 8, stopper slot 8.1, breach 8.2, fixed axis 9, axle 10, second cam 11, projection 11.1, the 4th bearing pin 12, extension spring 13, the 5th bearing pin 14, first torsion spring 15, second torsion spring 16, first mounting panel 17, second mounting panel 18, interlocking lever 19, deep-slotted chip breaker 20 etc.
As shown in Fig. 1 ~ 6, a kind of three-station switch-interlocking of the present invention device, comprise two pieces of first mounting panels 17 arranged in parallel, second mounting panel 18, described first mounting panel 17, between second mounting panel 18, top and bottom are fixedly installed fixed axis 9 respectively, first bearing pin 2, second bearing pin 3 is fixedly installed on the first mounting panel 17, between second mounting panel 18, corresponding to the top position place of the first bearing pin 2, second bearing pin 3 is provided with two boards 4, the 3rd bearing pin 5 is fixedly installed respectively near middle position and outer end between two boards 4, the 3rd bearing pin 5 outside being wherein positioned at rotates and is provided with roller 6, described second bearing pin 3 is also arranged with the first torsion spring 15, first cam 8 and the second torsion spring 16, first cam 8 is fixed with screw 7, described first torsion spring 15 one end is pressed on nearer with it the 3rd bearing pin 5, the other end is pressed on the first bearing pin 2, described second torsion spring 16 one end is pressed on screw 7, the other end is pressed on the first bearing pin 2, described first cam 8 forms stopper slot 8.1, and fixed axis 9 is placed in described stopper slot 8.1, axle 10 rotating support is upper position between the first mounting panel 17, second mounting panel 18, and on axle 10, be fixed with the second cam 11, described second cam 11 is fixedly installed the 4th bearing pin 12,4th bearing pin 12 two ends are stretched in the deep-slotted chip breaker 20 of the first mounting panel 17 and the formation of the second mounting panel 18 surface both respectively, described first mounting panel 17, second mounting panel 18 is also provided with the 5th bearing pin 14 between the two, and described 4th bearing pin 12 is connected by extension spring 13 with between the 5th bearing pin 14, also rotate between described first mounting panel 17 and the second mounting panel 18 and be provided with actuating cam 1, the edge of actuating cam 1 is formed with the first arc groove 1.1, second arc groove 1.2, three-arc groove 1.3, actuating cam 1 is in rotation process, and roller 6 matches with described first arc groove 1.1, second arc groove 1.2, three-arc groove 1.3 successively.
Described first torsion spring 15, first cam 8 is arranged between two boards 4.
Described axle 10 end winding support connects interlocking lever 19, and interlocking lever 19 offers lockhole.
Operation principle of the present invention is as follows: the second cam 11 pulls open (position as shown in Figure 1) via the 4th bearing pin 12 by extension spring 13 in an initial condition, now, the 4th bearing pin 12 be fixed on the second cam 11 is pulled to the lower end restriction site of the deep-slotted chip breaker 20 on the first mounting panel 17, the extreme position that the second cam 11 rotates.
The roller 6 be arranged between two boards 4 is pressed on the first arc groove 1.1 of actuating cam 1 by the 3rd bearing pin 5 and the first bearing pin 2 by the first torsion spring 15.
First cam 8, by being fixed on the screw 7 on the first cam 8, is pressed on the fixed axis 9 of the first mounting panel 17 and the second mounting panel 18 by the second torsion spring 16.
As shown in Figure 1, 2, now rotate actuating cam 1, because roller 6 at next vertical compression of torsion of the first torsion spring 15 on the circle contoured surface of actuating cam 1, drive actuating cam 1 that roller 6 can be made to move upward according to the center of the second bearing pin 3, and at this moment, second cam 11 is because the pulling force of extension spring 13, and the extreme position (shown in Fig. 1,2) the second cam 11 being in rotate, interlocking lever 19 is fixed on vertical position simultaneously.Now roller 6 can be crushed between actuating cam 1 and the second cam 11, and actuating cam 1 cannot be rotated, and thus three-station cannot switch.Thus reach when interlocking lever 19 is not operating, cannot station be switched.
As shown in Figure 3, operation interlocking handle 19, overcome the pulling force of extension spring 13, while rotation, second cam 11 contacts with the first cam 8 and overcomes the torsion of the second torsion spring 16, after operation interlocking handle 19 half-twist, now because the effect of the second torsion spring 16, the projection 11.1 of the second cam 11 is crushed in the breach 8.2 of cam 8.Now, interlocking lever 19 is fixed on horizontal level.
Under Fig. 3 state, rotate actuating cam 1, now, roller 6 can move upward along the outline of actuating cam 1 according to the center of the second bearing pin 3.As shown in Figure 3, after actuating cam 1 rotates a certain angle, because the second cam 11 is fixed, roller 6 can move to the profile peak of actuating cam 1 always, after peak, because roller 6 starts to start to move downward along the outline of actuating cam 1, actuating cam 1 also just can from initial Switch of working position to the second station, namely actuating cam 1 can operate a α angle, realizes the Switch of working position of three-station.
In Fig. 4 state, when actuating cam 1 rotate to make roller 6 move to peak time, the 3rd bearing pin 5 be fixed between two boards 4 is simultaneously also moved to peak.Now, the 3rd bearing pin 5 can head on the first cam 8 to left side motion after the torsion overcoming the second torsion spring 16, thus makes the first cam 8 throw off the second cam 11.After the second cam 11 throws off the first cam 8, because the pulling force effect of extension spring 13, the second cam 11 is started drag and resets to as Fig. 4 state.Switch after a α angle until actuating cam 1, as shown in Figure 6, under the twisting force of the first torsion spring 15, roller 6 moves to nadir along the outline of actuating cam 1; Second cam 11 is also drawn to diagram 5 state by extension spring 13, and now, all interlocks are all returned to initial condition, and three-station then completes the action switching station.Because all interlocks are to reply, make actuating cam 1 after switching station, cannot continue to move to the 3rd station, thus solve directly skip from the first station because actuating cam 1 is firmly excessive the problem that second station jumps to the 3rd station in the three station courses of work.
Because the concavo-convex curve on actuating cam 1 arranges according to the α even angle of Switch of working position, in like manner, if need by three-station from the second Switch of working position to the first station or the 3rd station, by after interlocking lever 19 half-twist, the work of Switch of working position just must can be continued.
In like manner, if when three stations are in the 3rd station, if needed by switch from the 3rd Switch of working position to the first station, because above-mentioned interlock, after switching over to the second station, an interlocking lever must be operated, could by switching over to the first station.
When there being demand, interlocking lever 19 having lockhole, if desired, only interlocking lever 19 and other parts need be locked fixing, three-station padlock function can be reached.
