Abstract
The utility model relates to an articulation connection device. The articulated connection device comprises two articulation pieces and a pin shaft, wherein one of the articulation pieces comprises two articulation lugs used as articulation parts, and a pin shaft hole for abrasion and deformation is formed in each articulation lug; and the other articulation piece is provided with an articulation part with a pin shaft hole, the articulation part is inserted between the two articulation lugs, and the two articulation pieces are connected together by inserting the pin shaft into the pin shaft holes of the two articulation pieces. The articulation connection device is characterized in that a pin shaft ring is arranged on the outer side of each articulation lug in a welding manner; a pin shaft hole matched with the pin shaft is formed in each pin shaft ring; and two ends of the pin shaft are inserted into the pin shaft holes of the pin shaft rings and are inserted into a cotter pin socket of the pin shaft through a cotter pin. When the articulation connection device is used for a hydraulic cylinder, the articulation piece with the articulation part is used as a piston rod of the hydraulic cylinder, and the articulation part of the articulation piece is used as a hydraulic cylinder lug ring. By adopting the articulated connection device, both the maintenance cost and the labor intensity are reduced.
Description
Technical field
The utility model relates to a kind of hinge linkage.
Background technique
Hinge linkage is used for plurality of devices, use hinge linkage as many places on the swing arm of shear line slitter edge press roll, Placement between oil hydraulic cylinder and swing arm often adopts hinged form, it is oil hydraulic cylinder bearing pin hinge linkage, easily cause the pin shaft hole inner wall abrasion after the long-term use of the pin shaft hole that coordinates with oil hydraulic cylinder, directly to open on swing arm as pin shaft hole, the swing arm volume is larger again, safeguard cumbersome, directly change often swing arm or carry out repair welding and again process.This all needs swing arm is disassembled, if directly change, cost compare is high.Even the aperture is smaller, although can repair welding manual grinding then, the pin shaft hole dimensional accuracy is difficult to guarantee; Make in this way new mechanical spare part and change, cost compare is high, especially large-scale mechanical spare part.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing hinge linkage, the utility model provides a kind of reduction maintenance cost, reduces a kind of hinge linkage of labor intensity.
This hinge linkage comprises two articulated elementss, bearing pin, and one of them articulated elements has two as the hinged ear of hinge point, and each hinged ear has the pin shaft hole of abrasion deformation; Another articulated elements has a hinge point with pin shaft hole, this hinge point is inserted between two hinged ears, two articulated elementss are linked together by the pin shaft hole that bearing pin is inserted in them, it is characterized in that: welding the bearing pin ring in the outside of each hinged ear, each bearing pin ring has a pin shaft hole that matches with bearing pin, the two ends of bearing pin are inserted in the pin shaft hole of bearing pin ring, and are inserted by cotter pin in the cotter pin jack of bearing pin.
Above-mentioned hinge linkage is characterized in that: described articulated elements with a hinge point is the piston rod of oil hydraulic cylinder, and the hinge point of this articulated elements is the oil hydraulic cylinder earrings.
At the both sides of the pin-and-hole that weares and teares welding upper pin ring, the internal diameter of bearing pin ring is consistent with former pin shaft hole diameter, and other sizes of bearing pin ring can design with the space situation as required.Simultaneously, preferably redesign bearing pin, with the distance of original bearing pin size and two bearing pin rings of location dimension lengthening.Newly-designed bearing pin coordinates with the bearing pin ring.And can be as required, the place increases the copper sheathing annex with life-saving or improves precision at the bearing pin ring.This structure is applicable to the be articulated and connected cooperation of mode of great majority.Adopt this hinge linkage, reduce maintenance cost, reduce labor intensity.
