Abstract

The invention discloses a machining method for a suspension bridge pin joint rope clip. The method uses a plain milling machine to substitute a deep hole drilling machine and a lathe to coarsely machine inner arc faces of two half rope clips, uses a locating tool to separately machine screw holes of the two half rope clips, uses an ordinary boring and milling machine to finish clamping at one time, firstly finely machines an inner hole formed by locking the inner arc faces of the two half rope clips and then rotates a work bench at 90 degrees to machine a pin hole with the inner hole as the base. The machining method is simple in process, high in machining efficiency, low in machining cost, capable of well guaranteeing the verticality of the screw holes and further capable of obviously improving the position accuracy of the pin hole.

Description

A kind of processing method of suspension bridge pin joint type cord clip
Technical field
The present invention relates to a kind of processing method of component of machine, relate in particular to a kind of processing method of suspension bridge pin joint type cord clip.
Background technology
Cord clip is provided in a side of a kind of hardware on main rope of suspension bridge, clamps main push-towing rope and connects hoist cable, and whole suspension bridge and load-carrying thereof are passed to main push-towing rope by cord clip, and therefore, cord clip is the important stressed member of suspension bridge.Because main rope of suspension bridge is linear, it is space curve, not identical with horizontal plane angle everywhere at main push-towing rope, for the hoist cable Bending stress of avoiding being connected with cord clip, different angles need to be arranged for pin joint type cord clip endoporus and pin-and-hole and main push-towing rope is linear adapts, and the position accuracy demand of pin-and-hole that therefore connects hoist cable is higher.The pin joint type cord clip of suspension bridge is mainly formed by high-strength bolt is sealed by upper and lower two halves cord clip, existing processing method be adopt milling machine processing two halves cord clip in conjunction with plane, again two halves cord clip point postwelding is adopted to the whole processing bolt of drilling machine hole, then penetrate screw rod sealed, adopt deep hole drilling machine or lathe processing endoporus, adopt digital display boring and milling machine pin hole processing.The method has the following disadvantages: 1., owing to adopting deep hole drilling machine or lathe processing endoporus, the cord clip blank is steel-casting, and cast(ing) surface is coarse, and endoporus allowance is generally larger, and hardness is large, contains the hard spots such as burning into sand in interior tissue, processes length consuming time, and working (machining) efficiency is low; 2. by the sealed rear whole processing screw hole of two halves cord clip, because hole depth is larger, hole perpendicularity is difficult to assurance, and machining accuracy is poor, and working (machining) efficiency is low; 3. due at deep hole drilling machine or lathe fine finishining endoporus, then take endoporus as the benchmark pin hole processing on boring and milling machine, have the secondary clamping problem, the pin hole processing positional precision is poor.
CN101559563B provides " a kind of processing technology of cord clip ", this technique comprise line, two halves cord clip mill respectively lower plane, boring and connect together, Li Cheche or boring machine boring two ends male half coupling d, spot welding two ends endoporus car reach drawing and technological requirement to technique backing ring, the sleeping carriage frame bracket car endoporus of D.This technique has and takies large-scale finish machining equipment small investment, working (machining) efficiency is high, the advantage that processing cost is low, but exist following not enough: 1. cord clip spray endoporus surplus is generally larger, adopt the moulding of sleeping carriage processing endoporus time processing, forming residual stress is large, and after processing, endoporus easily produces moderate finite deformation, and inner hole precision is difficult to guarantee; 2. by scribing position, adopt common driller to bore screw hole, hole location and perpendicularity are poor, affect two halves cord clip screw rod sealed; 3. adopt this processes pin joint type cord clip, endoporus and pin-and-hole fine finishining adopt distinct device, have secondary clamping, and the pin-and-hole positional precision is poor.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of intrados that adopts plain-milling machine to substitute deep hole drilling machine and lathe roughing cord clip is provided, adopt the screw hole of common driller and positioning tool separate machined cord clip, adopt the endoporus of common boring and milling machine clamped one time fine finishining cord clip and take endoporus as the benchmark pin hole processing, on the basis that guarantees screw hole perpendicularity and pin-and-hole positional precision, the processing method of a kind of suspension bridge pin joint type cord clip that improve working (machining) efficiency, cuts down finished cost.
The object of the present invention is achieved like this: a kind of processing method of suspension bridge pin joint type cord clip, comprise line, screw rod boss face, faying face and the processing of screw rod deep gouge, screw hole processing, intrados and pin-and-hole processing, it is characterized in that: described screw hole processing adopts drilling machine and positioning tool separately to carry out, described intrados and pin-and-hole processing first adopt milling machine to carry out roughing to intrados, again that the two halves cord clip is sealed, adopt boring and milling machine to carry out fine finishining to the endoporus of the sealed one-tenth of two halves cord clip intrados, then take endoporus as the benchmark pin hole processing.
The processing of described screw rod boss face, faying face, screw rod deep gouge and the roughing of intrados are to place equal height cushion block on the plain-milling machine workbench, by the faying face of two halves cord clip, evenly be placed on equal height cushion block down, centering, clamping, adopt milling cutter to mill the screw rod boss face and put in place, then, by two halves cord clip turn-over, the screw rod boss face is placed on equal height cushion block down, centering, clamping, mill faying face and screw rod deep gouge to size, then the intrados of two halves cord clip carried out to roughing, stay allowance for finish.
Described screw hole processing is to place equal height cushion block on the common driller workbench, the faying face of the two halves cord clip put in place in connection with face, screw rod boss face, the processing of screw rod deep gouge upward, evenly be placed on equal height cushion block, again positioning tool is placed in the screw rod deep gouge, by the location of positioning tool, processes respectively screw hole.
Described positioning tool is comprised of screw rod and locating piece, and locating piece is screwed in the two ends of screw rod, and the middle part of locating piece is provided with pilot hole.
Described intrados and pin-and-hole processing are that the two halves cord clip that roughing is put in place is sealed, be placed on the equal height cushion block of common boring and milling machine workbench, centering, clamping, adopting facing head, with addition of long boring bar, the endoporus of the sealed one-tenth of two halves cord clip intrados is carried out to fine finishining puts in place, by 90 ° of work table rotations, take endoporus as benchmark employing Common boring cutter pin hole processing again.
Compared with prior art, beneficial effect of the present invention is:
1, because the intrados that adopts milling machine to the two halves cord clip carries out roughing, working (machining) efficiency is high, has reduced processing cost.
2, adopt positioning tool separately to bore screw hole, because hole depth reduces, hole perpendicularity is guaranteed, and the screw hole positional precision is high, is convenient to the two halves cord clip sealed, has improved machining accuracy, and working (machining) efficiency is high.
3, owing to adopting boring and milling machine to carry out fine finishining to the endoporus by the sealed one-tenth of two halves cord clip intrados, the inner hole precision after processing is high, then take endoporus as the benchmark pin hole processing, clamped one time, and processing cost is low, and the pin-and-hole positional precision is high.
