Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, technical solutions according to the invention are described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, pin shear of the present invention, comprise the body 1 being with pre-and post perforative through hole, body 1 is also offered the groove 11 vertically running through body 1 and through hole, body 1 is stretched out after the through hole of carriage release lever 2 on body 1, first block 31 is locked at the front end of carriage release lever 2 by the first securing bolt 91, on carriage release lever 2, activity is arranged with press rods 4, the front end of press rods 4 is resisted against on the first block 31, arranges and can drive carriage release lever 2 in through-holes from rear to the driving mechanism of front slide between press rods 4 and body 1; In the present embodiment, the structure of described driving mechanism is: the fixed block 5 being set on carriage release lever 2, fixed block 5 between press rods 4 and body 1 and fixed block 5 be fixedly connected on the front end of body 1, the front end of fixed block 5 is provided with the first scarp, the 2nd scarp it is provided with in the rear end of press rods 4, first scarp and the 2nd scarp are mutually involutory, when press rods 4 rotates on carriage release lever 2,2nd scarp is fitted on the first scarp and rotates relative to the first scarp, forces carriage release lever 2 to slide in body 1.Second gear block 32 is locked at the rear end of carriage release lever 2 by the 2nd securing bolt 92, is provided with the resetting mechanism that the carriage release lever 2 after making slip resets between body 1 and second gear block 32, in the present embodiment, the structure of described resetting mechanism is: the return spring 7 being set on carriage release lever 2, on the rear end that the two ends of return spring 7 are resisted against body 1 respectively and second gear block 32. pin insertion block 6 is from the upper end insertion body 1 of groove 11 and is fixedly installed in body 1 by securing bolt 95, its lower plane is arranged in groove 11 and contacts with carriage release lever 2, insert at pin and block 6 is provided with different pin insertion hole 61, some apertures, carriage release lever 2 is provided with some and that each pin insertion hole 61 is corresponding respectively the first through hole 21, when carriage release lever 2 is positioned at original position under the effect of return spring 7, as shown in Figure 3, it is inserted in the first corresponding through hole 21 for processing the starting material bar 10 of pin by inserting hole 61 with the pin that its diameter mates mutually, in the present embodiment, on the carriage release lever 2 of cylindrical shape milling have on plane, lower plane and the upper flat face of pin insertion block 6 are tactile. the setting of upper plane, the phenomenon that can prevent to rotate because of circumference when carriage release lever 2 slides in through-holes thus cause pin insertion hole 61 to misplace with the first corresponding through hole 21, can guarantee that bar 10 inserts hole 61 by pin and is inserted in the first corresponding through hole 21 so better. the carriage release lever 2 relative with the lower end of groove 11 has been offered the first groove 22, lower end at groove 11 offers the 2nd groove 12 wider than groove 11, is provided with for controlling length that bar 10 stretches out from the first through hole 21 times ends thus the regulating mechanism of length of pin after controlling to shear in first, second groove 22 and 12. in the present embodiment, the structure of described regulating mechanism is: the slide block 8 being arranged in the 2nd groove 12, slide block 8 can slide in the 2nd groove 12 and be locked in body 1 by the 3rd securing bolt 93, stretch in the first groove 22 after the 2nd through hole of caging bolt 94 on slide block 8, caging bolt 94 is installed with the setting nut 9 stretching into the length in the first groove 22 for controlling caging bolt 94, when carriage release lever 2 is positioned at original position under the effect of return spring 7, as shown in Figure 3, caging bolt 94 is positioned at the underface of certain the first through hole 21 that the diameter with bar 10 mates mutually.
The principle of work of the present invention is as follows: when carriage release lever 2 is positioned at original position under the effect of return spring 7, as shown in Figure 3, now, pin insertion hole 61 communicates with the first corresponding through hole 21, bar 10 to be sheared can by being inserted in the first corresponding through hole 21 with the pin insertion hole 61 that its diameter mates mutually, adjustment regulating mechanism makes caging bolt 94 be positioned at the underface of the first through hole 21 mated mutually with bar diameter, then according to the length rotating adjusting nut 9 of required pin, adjust the distance between the first through hole 21 and caging bolt 94, the present embodiment is described to process the pin with the first through hole 21 equal length, rotating adjusting nut 9, the upper end of caging bolt 94 is made to be resisted against in the first groove 22, and the lower port of the first through hole 21 is sheltered from, as shown in Figure 1, bar 10 to be sheared is by being inserted in the first corresponding through hole 21 with the pin insertion hole 61 that its diameter mates mutually, and make the lower end abutment of bar 10 on the upper end of caging bolt 94.Then pressing press rods 4 makes it rotate relative to fixed block 5, the 2nd scarp being fitted on the first scarp also rotates relative to the first scarp, press rods 4 is forced to be moved forward, thus drive carriage release lever 2 to slide from back to front in through-holes and make pin insertion hole 61 and the first through hole 21 mutual dislocation, thus the bar that the bar being arranged in the first through hole 21 inserts hole 61 with pin is separated, as shown in Figure 4, the pin that the bar being arranged in the first through hole 21 after separation obtains after being shearing, the pin obtained after shearing drops from the first through hole 21. Unclamping press rods 4, carriage release lever 2 returns back to original position under the effect of return spring 7, is then down inserted bar 10 to be sheared and makes the lower end of bar 10 again be resisted against on the upper end of caging bolt 94, can shear again next pin.
It is an advantage of the invention that: structure is simple, easy to use, and the pin of multiple dimensions can be sheared, and the setting of regulating mechanism, it is possible to the length of rear pin is sheared in control flexibly, meets the needs of customers.
