As above-mentioned scheme, intermediate transfer based on the hinge lever construction, cylinder axis is changed into first ambulatory splint with respect to the reciprocal rotation radially of second ambulatory splint to the driving force of output, namely forms the radially opening and closing active force that clamps briquetting between first ambulatory splint, second ambulatory splint.
Because leverage is superimposed on the arm of force of first ambulatory splint, can form bigger clamping dynamics.
And the axial driving force of cylinder output can form the retaining restriction at first ambulatory splint through the hinge lever construction, thereby clamped condition is comparatively stable between first ambulatory splint, second ambulatory splint, is not prone to problem such as get loose.
For realizing the above-mentioned purpose of design of the utility model more efficiently, can take following comparatively preferred hinge lever construction:
Include for the first clamping plate bearing that connects first ambulatory splint and holder;
The first clamping plate bearing is connected in holder by the long support axle, and the first clamping plate bearing is connected in connecting rod by short back shaft, and the other end of connecting rod is connected in the drive rod of cylinder by the switching hinge.
In above-mentioned hinge lever construction, can adopt bearing pin to connect switching hinge and connecting rod and lack back shaft and connect connecting rod and the first clamping plate bearing to form second hinge point to form first hinge point that whole driving force is transmitted, to adopt.
Adopt the long support axle to connect the first clamping plate bearing and holder to form the central point that rotates, namely form first ambulatory splint carries out radially opening and closing with respect to second ambulatory splint pivot point.
For detecting the cutting silk particular location of finishing after tire cuts exactly, can on first ambulatory splint or second ambulatory splint, be provided with the position detecting device for detection of cutting silk position.
Be tire bead, the different types of tyre cutting location that adapts to different structure, can take following improvement project adjustable to realize the distance that is installed between the paired clamp assembly that clamps the support plate two ends, described holder both sides are slidably connected in the chute that clamps support plate by cylindrical pin with external thread respectively.
Clamp briquetting at the clamping effect of tire for improving, described clamping briquetting integral body is the triangle hub-and-spoke configuration, and its three limits are provided with for the triangular groove that strengthens friction; The centre of clamping briquetting is carried out axle by elastic cylindrical pin and is established the end that is connected in first ambulatory splint, second ambulatory splint.
In sum, the utility model tire cutting and clamping device has the following advantages and beneficial effect:
1, solved the chucking power of existing pneumatic gripping device existence than minor issue, change axial driving force into briquetting radially the opening and closing power each other that clamps by the hinge lever construction, thereby improve the clamping dynamics significantly, more firm at the positioning action that is cut tire.
2, by hinge lever transferring structure, can reduce pneumatic gas pawl quantity significantly, thereby reduce outsourcing piece quantity, optimize equipment cost.
3, integrated clamp device is simple for structure, and can adjust the distance between the clamp assembly easily, namely uses a cover clamping device can be applicable to tire bead, the different types of tyre cutting demand of different structure.
4, position-based detects the automatic cutting operation that can realize tyre cutting device, reduces the additional workload of manual intervention.
