Description of drawings
Fig. 1 is the structural representation of the utility model first mode of execution wind wheel locking device;
Fig. 2 is the utility model wind wheel locking device clamp structural representation;
Fig. 3 is the structural representation of the utility model second mode of execution wind wheel locking device.
Embodiment
Fig. 1 and Fig. 2 have illustrated first mode of execution of the present utility model.
As shown in Figure 1, wind wheel locking device of the present utility model has comprised base 6, mechanical pins 1, rocking bar 2, is provided with a hole on base, and mechanical pins is provided with in the present hole, and mechanical pins is slided before and after can being present in the hole.The front end correspondence of mechanical pins the positioning hole of main shaft positioning disk 9, and during work, mechanical pins is inserted in the hole of positioning disk, plays the effect of locking.
Be provided with a bearing 5 on base, bearing 5 is installed on the base, also can be one-body molded with base.One end of rocking bar connects by bearing pin 4 and bearing, and rocking bar can rotate around bearing, and the mechanical pins end is connected the rocking bar medium position, when rocking bar rotates around bearing, can drive the mechanical pins motion., use bearing pin to connect just schematically herein, the utility model is not limited thereto kind of a bind mode.In addition, mechanical pins is connected the rocking bar middle part, connection herein should be made broad understanding, be not with mechanical pins and rocking bar fixed-site, but rocking bar and mechanical pins are in the state of interlock, drive mechanical pins by rocking bar, in embodiment, a pin 3 is installed in the flat back of the back end mill of mechanical pins, at the middle part of rocking bar one kidney slot is set, and pin is arranged in this kidney slot.
The utility model is installed a kind of leverage at the rear portion of mechanical pins, and a people pulls rocking bar, can easily finish the action of spindle lock and relieving, and is laborsaving 2/3, and finishes mechanical positioning.
Preferably, in the present embodiment, also be provided with the positioning part, be used to locate the position of mechanical pins at the afterbody of mechanical pins.The mechanism of this positioning part is unrestricted, and is for example known, at the mechanical pins afterbody aperture is set, and locatees by latch; Groove perhaps is set, the clamp location.It should be appreciated by those skilled in the art that orientation type herein is not limited to the mode that present embodiment discloses, the mode of mechanical pins mobile position, any realization location all can realize the object of the invention, all in protection domain of the present utility model.
In the present embodiment, preferred, the positioning part is a groove,, is provided with groove at the afterbody of mechanical pins that is, and is corresponding, and a clamp 7 is set on base, and as shown in Figure 2, clamp limits the position of mechanical pins by blocking groove.Clamp one end is the link joint end, is bound up on the described base, and clamp can rotate around this connecting end, and the clamp the other end is free end, and is movable, also can be by pin or screw locking.
With clamp free end corresponding position one stroke switch 8 is being set, the trip switch 8 and clamp interlock, promptly stroke switch 8 judges by the position of identification clamp whether clamp blocks groove, and then judges the position of mechanical pins.When clamp is connected in the groove, touch position limit switch, system can discern automatically.
Preferably, in the present embodiment, be provided with two grooves at least on mechanical pins, and at least two grooves have the different degree of depth, promptly one is deep trouth, and one is shallow slot, can be in the position of two limit positions location mechanical pins.And preferred, in the present embodiment, circular groove is set on mechanical pins.
According to the wind wheel locking structure shown in the present embodiment, when pulling rocking bar forward with hand, mechanical pins is slided in base, behind the arrival working position, puts down clamp, the clamp free end is locked, clamp is stuck in the dark annular groove of mechanical pins and locatees, to guarantee causing that at wind-force mechanical pins can not move under the situation of vibration, and clamp free end depression stroke switch simultaneously, give signal of system, expression wind wheel main shaft is in the locked position; After work is finished, the clamp free end is unclamped, lift clamp, pull rocking bar with hand then backward, mechanical pins is withdrawed from the main shaft positioning disk, after falling back on the position, put down clamp again, be stuck in the shallow slot of mechanical pins, because the shallow slot degree of depth is not enough, clamp can't be pressed onto on the position limit switch, has so both guaranteed that mechanical pins is return to put in place, can allow system identification be off working state at this moment again.
Fig. 3 has illustrated the structural representation of the utility model second mode of execution.Wherein identical with first mode of execution part no longer describes in detail, the structure that the emphasis narration is different with first mode of execution.As shown in Figure 3, in the present embodiment, the end of mechanical pins is provided with two fixing pins 10, and rocking bar is arranged between two fixing pins 10.When rocking bar rotates, can drive the motion of fixing pin 10 and mechanical pins.
In addition, the terminal ways of connecting of rocking bar and mechanical pins is not limited to embodiment of the present utility model, and as also can one groove being set at the mechanical pins end, rocking bar passes this groove etc.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
