Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A partial sectional view of Fig. 1;
Fig. 3 is the B-B partial sectional view of Fig. 1.
The specific embodiment
Referring to Fig. 1, stirrup bender comprises frame 1, kidney basin 2 and the driving mechanism that is made of reducing motor 5, travelling gear 6,7 and driving shaft 4.Motor 5 drives driving shaft 4 rotations by gear 6,7, is driven rotating shaft 3 rotations of kidney basin again by driving shaft 4.Kidney basin rotating shaft 3 is rotated with frame 1 and is connected.Driving shaft 4 connects with kidney basin rotating shaft 3 by one-way clutch, and the transmission direction of one-way clutch is consistent with the direction of rotation that driving shaft 4 drive kidney basins 2 carry out the bar bending operation.The one-way clutch of present embodiment is a jaw clutch, by forming by the half- clutch device 8,9 of notched teeth on two end faces, utilize notched teeth can transmit bigger torque, and characteristics that only can one-way only operation, can guarantee that driving shaft 4 can only drive kidney basin rotating shaft 3 rotations towards correct direction.A half-clutch device 8 in the jaw clutch is fixedly connected with kidney basin rotating shaft 3, and another half-clutch device 9 is fixedly connected with driving shaft 4, and the mode that is fixedly connected comprises usual manners such as key connecting, welding.As preferred forms, the driving shaft 4 of present embodiment is a hollow shaft, is enclosed within slidably in the kidney basin rotating shaft 3 also can freely rotate.Because driving shaft 4 is enclosed within the kidney basin rotating shaft 3, therefore when assembling, need not to consider the offset problem of driving shaft 4 and kidney basin rotating shaft 3 fully, also need not to consider the offset problem between the two halves clutch 8,9, assemble simple and convenient.Present embodiment makes driving shaft 4 constitute the axle sleeve of half-clutch device 9 also with driving shaft 4 and half-clutch device 9 global formations, so more helps further simplified structure.
The clutch operating device of present embodiment comprises a lever 10, and an end of lever 10 connects with driving shaft 4 axial restraints and rotation, and the other end of lever 10 connects with a pedal 12 by spring 11.During manipulation, step on pedal 12, drive levers 10 by spring 11 and swing up and down, drive driving shafts 4 by lever 10 again and slide vertically, the joint that can handle two half- clutch devices 8,9 thus with separate.Connect with spring 11 between lever 10 and the pedal 12, can make the operator feel soft comfortable.As lever 10 and driving shaft 4 axial restraints and rotate the optimum structure form that connects, simultaneously referring to Fig. 1, Fig. 2, present embodiment is provided with a circle annular groove 13 on driving shaft 4, the end that lever 10 connects with driving shaft 4 is shift fork shape, and shift fork 14 is enclosed within the annular groove 13 of driving shaft.Shift fork 14 both can drive driving shaft 4 and slide up and down, and can not hinder the rotation of driving shaft 4 again.For reducing the frictional force between shift fork and annular groove, shift fork 14 is provided with the roller 15 that rolls along annular groove 13.Present embodiment is made of the crack between half-clutch device 9 and the gear 7 at the annular groove 13 that is provided with on the driving shaft 4, in addition, also can directly go out a circle annular groove with the lathe car on driving shaft 4 or half-clutch device 9.For two half-clutch devices can be separated rapidly, present embodiment also is provided with compression spring 16 between two half- clutch devices 8,9.
Reset for kidney basin 2 can be turned round rapidly after clutch separation automatically, also be connected with the spring 17 that can produce moments to kidney basin rotating shaft 3 in kidney basin rotating shaft 3, the direction of moment is opposite with the direction of rotation that driving shaft 4 driving kidney basins 2 carry out the bar bending operation.The spring 17 of present embodiment is an extension spring that is hooked in prejudicially in the kidney basin rotating shaft 3.
As further improvement, also can between kidney basin rotating shaft 3 and frame 1, the rotational angle induction installation be set.Referring to Fig. 1, Fig. 3, the rotational angle induction installation of present embodiment is by a cam 18 that is fixed in the kidney basin rotating shaft 3, and the travel switch 20 that is installed on the arc-shaped guide rail 19 constitutes, arc-shaped guide rail 19 is installed in the position of close cam 18 on the frame 1, makes the peak of cam 18 working faces just to touch with travel switch 20.During use, the position of angular adjustment travel switch 20 on arc-shaped guide rail 19 according to kidney basin 2 required rotations, make that cam 18 just touches with travel switch 20, just can control the bar bending angle easily by control circuit when kidney basin 2 turns to set angle.According to actual needs, a plurality of travel switches 20 can be installed on arc-shaped guide rail 19, to control different angle of bend.In addition, as sensor, can also control motor when cam 18 just touches with travel switch 20 with travel switch 20 by control circuit, of short duration immediately the counter-rotating so more helps the rapid separation of jaw clutch.
Above embodiment is only for the usefulness of understanding the utility model, be not to restriction of the present utility model, the utility model can also have other specific embodiment, for example, except extension spring, can also adopt other springs in order to the spring 17 that kidney basin rotating shaft 3 is produced flywheel moment, and spring 17 except directly with kidney basin rotating shaft 3 connects, can also connect with other parts that is fixed in the kidney basin rotating shaft 3, needing only the spring that is connected can provide automatic revolution required moment for kidney basin rotating shaft 3; The notched teeth of clutch can also adopt pinnacle, the non-standard saw shape tooth at the point end except the flat-top shown in the figure, flat standard tooth form; Described clutch operating device can also adopt other operating mechanisms such as pneumatic type, electromagnetic type; Described rotational angle induction installation can also adopt the photo-electric induction installation; On frame more travel switch can also be installed, for example travel switch 22 etc. is moved in the limit travel switch 21 among Fig. 3, the stop and start of falling, to improve the security and the property convenient for control of stirrup bender.And so on, all variation or modification that covered the claim technical characterictic all belong at protection domain of the present utility model.
