Abstract
The invention belongs to an assembling technology and relates to a hinge pin shaft bending tool. The hinge pin shaft bending tool is characterized by comprising an upper clamping plate [2], a lower clamping plate [4], two rubber pads [3] and four bolts [1]. The hinge pin shaft bending tool can avoid damaging a hinge body, ensure the accuracy of the bending radius and improve the qualified rate of products.
Description
Technical field
The invention belongs to mounting technology, relate to a kind of hinge bearing pin bending tool.
Background technology
Add man-hour in the aircraft assembling, often need carry out bending, because this bearing pin is thinner the bearing pin termination of hinge; After having worn bearing pin; Workman oneself clamps the direct bending bearing pin of hinge termination with vice often, and clamping force is wayward, causes the damage of involutory page body easily; In addition, be difficult to control radius bend, cause scrapping of product sometimes.
Summary of the invention
The objective of the invention is: propose a kind of hinge bearing pin bending tool,, guarantee the degree of accuracy of radius bend, improve the qualification rate of product to avoid damaging the hinge body.
Technical scheme of the present invention is: a kind of hinge bearing pin bending tool is characterized in that it is made up of train wheel bridge 2, lower plate 4, two rubber blankets 3 and 4 screws 1; Train wheel bridge 2 is rectangular slabs of 90 ° of downward bendings of right-hand member; Respectively there is a screw via hole at 4 jiaos of places in the rectangular top surface of train wheel bridge 2; There is a semicircle orifice at the center of 2a lower limb in the rectangle right side of train wheel bridge 2, and the radius of this semicircle orifice equals to treat the radius of the bearing pin 5 of bending hinge; Lower plate 4 is make progress rectangular slabs of 90 ° of bendings of a right-hand member; The overall size of lower plate 4 is identical and symmetrical with train wheel bridge 2; Respectively there is a screwed hole at 4 jiaos of places in the rectangular top surface of train wheel bridge 2; The position of 4 screwed holes is corresponding one by one with screw via hole on the train wheel bridge 2; There is a semicircle orifice at the center of 4a top edge in the rectangle right side of lower plate 4, and the radius of this semicircle orifice equals to treat the radius of the bearing pin 5 of bending hinge, and the semicircle orifice of the semicircle orifice of lower plate 4 and train wheel bridge 2 is combined to form complete circular hole; The hinge body 6 of treating the bending hinge is between train wheel bridge 2 and lower plate 4; The right-hand member of treating bending hinge bearing pin 5 stretches out from the circular hole that the right side 4a lower limb of the right side 2a lower limb of train wheel bridge 2 and lower plate 4 is combined to form, and between hinge body 6 upper surfaces of the lower surface of train wheel bridge 2 and bending hinge, a rubber blanket 3 is arranged, and between hinge body 6 lower surfaces of the upper surface of lower plate 4 and bending hinge, another rubber blanket 3 is arranged; 4 screws 1 pass respectively and are screwed into behind 4 screw via holes of train wheel bridge 2 on the lower plate 4 in corresponding 4 screwed holes.
Advantage of the present invention is: avoided damage hinge body, guaranteed the degree of accuracy of radius bend, improved the qualification rate of product.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the cutaway view of Fig. 1, and section is crossed the axis of bearing pin and perpendicular to the upper surface of train wheel bridge 2.Dotted line is represented the state after the bending of bearing pin termination among Fig. 2.
The specific embodiment
Explain further details in the face of the present invention down.Referring to Fig. 1,2, a kind of hinge bearing pin bending tool is characterized in that, it is made up of train wheel bridge 2, lower plate 4, two rubber blankets 3 and 4 screws 1; Train wheel bridge 2 is rectangular slabs of 90 ° of downward bendings of right-hand member; Respectively there is a screw via hole at 4 jiaos of places in the rectangular top surface of train wheel bridge 2; There is a semicircle orifice at the center of 2a lower limb in the rectangle right side of train wheel bridge 2, and the radius of this semicircle orifice equals to treat the radius of the bearing pin 5 of bending hinge; Lower plate 4 is make progress rectangular slabs of 90 ° of bendings of a right-hand member; The overall size of lower plate 4 is identical and symmetrical with train wheel bridge 2; Respectively there is a screwed hole at 4 jiaos of places in the rectangular top surface of train wheel bridge 2; The position of 4 screwed holes is corresponding one by one with screw via hole on the train wheel bridge 2; There is a semicircle orifice at the center of 4a top edge in the rectangle right side of lower plate 4, and the radius of this semicircle orifice equals to treat the radius of the bearing pin 5 of bending hinge, and the semicircle orifice of the semicircle orifice of lower plate 4 and train wheel bridge 2 is combined to form complete circular hole; The hinge body 6 of treating the bending hinge is between train wheel bridge 2 and lower plate 4; The right-hand member of treating bending hinge bearing pin 5 stretches out from the circular hole that the right side 4a lower limb of the right side 2a lower limb of train wheel bridge 2 and lower plate 4 is combined to form, and between hinge body 6 upper surfaces of the lower surface of train wheel bridge 2 and bending hinge, a rubber blanket 3 is arranged, and between hinge body 6 lower surfaces of the upper surface of lower plate 4 and bending hinge, another rubber blanket 3 is arranged; 4 screws 1 pass respectively and are screwed into behind 4 screw via holes of train wheel bridge 2 on the lower plate 4 in corresponding 4 screwed holes.
Method for using of the present invention is: the hinge body thickness of bending is selected the rubber blanket of suitable thickness as required before bending; The hinge body is placed between train wheel bridge and the lower plate; Protect with rubber blanket; With treating that bending hinge bearing pin uses the circular hole that clamping plate right side lower limb and lower plate right side lower limb be combined to form and have good positioning, tighten 4 screws at last, through train wheel bridge and lower plate the hinge body is compressed.After hinge body and hinge bearing pin fixed to clamp, the workman just can knock the right-hand member of hinge bearing pin with the rubber hand hammer downwards, with the right-hand member bending of hinge bearing pin.
The present invention has realized the location and the clamping of hinge bearing pin through the fixation of train wheel bridge and lower plate, has eliminated the deficiency of in the past not having bearing pin bending specific purpose tool, the damage of involutory page body when having reduced bending.Adopt the present invention that the hinge bearing pin of certain type aircraft is carried out Bending Processing, product percent of pass rises 100% from 80%.
