Embodiment
below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is further elaborated.
below about in the definition in direction, be all that the direction of piston rod movement defines when working according to this double acting cylinder, the direction of the outside movement of piston rod opposing cylinder is front, otherwise be after, that is the left and right directions in Fig. 3 to Fig. 5, after wherein left is, right is front.
see the double acting cylinder shown in Fig. 3 to Fig. 5, can be oil hydraulic cylinder or cylinder, it front cover 3 comprising cylinder body 1, be fixedly arranged on the rear end cover 2 of cylinder body 1 rear end, be fixedly arranged on cylinder body 1 front end, and the piston rod 4 be located in cylinder body 1, the inner chamber of cylinder body 1 is separated to form the left pressure chamber and right pressure chamber that are isolated by piston rod 4.Rear end cover 2 is provided with the first oil hole/inlet hole 21 be communicated with left pressure chamber, front cover 3 is provided with the second oil hole/inlet hole 31 be communicated with right pressure chamber, control fuel feeding or air feed in pressure chamber or right pressure chamber left by solenoid valve 7, can move forward and backward by piston rod 4 opposing cylinder 1.
piston rod 4 offers endoporus 41, hinged-support 5 is fixedly provided with in this endoporus, here endoporus 41 is set to the through hole running through piston rod 4 along the longitudinal direction, hinged-support 5 is tightly connected with the circumferential side wall of endoporus 41 and arranges, and hinged-support 5 is located in endoporus 41 by the mode when mounted by interference fit.
the front end of hinged-support 5 is hinged with swing arm 6, and the rear end of swing arm 6, also can be hinged on hinged-support 5 according to the mode of bulb hinged by hinge on hinged-support 5.The front end of endoporus 41 is coniform setting, and this coniform setting for being increased gradually by backward front aperture, to step down to the swing of swing arm 6.The front end of swing arm 6 is positioned at the outside of endoporus 41, and the front end of swing arm 6 then connects the take-off lever group 8 for Power output.
in the present embodiment, this take-off lever group 8 comprises the first bar 81, second bar 82, drift 83.One end of first bar 81 is hinged in frame, and its other end is hinged on the front end of swing arm 6, and one end of the second bar 82 is hinged on the front end of swing arm 6, and its other end is hinged on drift 83, and drift 83 can be vertically located in frame up and down.
when original state, as shown in Figure 3, piston rod 4 is positioned at the rear portion of cylinder body 1.When needs piston rod 4 moves forward, as shown in Figure 4, solenoid valve 7 commutates, left pressure chamber injection liquid force feed or be filled with pressurized gas, the hydraulic oil in right pressure chamber is back to fuel tank gradually or pressurized gas passes into air, and piston rod 4 moves forward, piston rod 4 acts on swing arm 6 when moving forward, swing arm 6 then swings and acts on the first bar 81, second bar 82 in endoporus 41, drives the first bar 81 and the second bar 82 to swing and drive drift 83 to move down to realize impacting, as shown in Figure 5.
after piston rod 4 travels forward end, solenoid valve 7 commutates, injection liquid force feed or be filled with pressurized gas in pressure chamber to the right again, piston rod 4 moves gradually backward, until complete reset, drive swing arm 6 to swing in the process of moving after piston rod 4, swing arm 6 acts on the first bar 81 and the second bar 82 and drives drift 83 to move reset vertically.
certainly, when take-off lever group 8 is other mechanisms, the mechanism that swing arm 6 can connect according to it needs output reciprocally swinging or other on-rectilinear movements.
to sum up, hinged interior rod-type double acting cylinder of the present utility model, it can be used as oil hydraulic cylinder or cylinder, this double acting cylinder compares traditional oil hydraulic cylinder and cylinder, due to piston rod 4 offering endoporus 41, and swing arm 6 is hinged on the hinged-support 5 in endoporus 41, solving traditional oil hydraulic cylinder and cylinder only can the defect of outputting reciprocating linear movement, and this double acting cylinder can export the on-rectilinear movements such as reciprocally swinging.This compares the mode of the front end articulated linkage of the piston rod of traditional Fixed-hydraulic cylinder and cylinder, greatly reduces axial dimension; And compare oil hydraulic cylinder or the cylinder of rear end hinge, swinging unit quality significantly reduces, thus reduces the negative effect impacted and bring significantly.
