Abstract
The invention relates to an error proofing method for assembling a coupling of a fuel oil injection pump. The error proofing method for assembling the coupling of the fuel oil injection pump comprises the steps that error-proof shifting fork rod is installed beside the coupling, the size of an inner clamp of the error-proof shifting fork rod is 21.5mm, the outer diameter of each riveting ring of a sheet steel component is 22.1mm, and the outer diameter of each riveting sleeve is 21mm; when an operator pulls a shifting rod handle manually, the inner clamp of the error-proof shifting fork rod passes through each riveting ring, the operator screws up screws through a pneumatic torque wrench so that the sheet steel component can be connected with a cross joint, and strength of connection between the sheet steel component and the cross joint is normal; if the shifting fork rod is stuck, the sheet steel component is misplaced by 90 degrees, and the operator stops screwing up the screws. The error proofing method for assembling the coupling of the fuel oil injection pump has the advantages that the phenomena that due to the fact that the sheet steel component is wrongly installed artificially, the strength of connection between the sheet steel component and the cross joint is reduced after the screws are screwed up, and accidents are caused are avoided, the requirement for assembling the coupling is met, performance is reliable, and use is convenient.
Description
Technical field
The present invention relates to a kind of fuel injection pump, relate in particular to a kind of shaft coupling assembling error-preventing method of fuel injection pump.
Background technology
In shaft coupling assembling steel disc parts, there are 2 riveting rings, 2 riveting sleeves to be 90 degree and to distribute, when steel disc parts and crossed joint assembly connection, because 2 riveting sleeve sizes are close, operator easily misplaces position by steel disc parts 90 degree, causes steel disc parts and the reduction of crossed joint bonding strength after screw-driving.
Summary of the invention
The technical issues that need to address of the present invention have been to provide a kind of shaft coupling assembling error-preventing method of fuel injection pump, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes by following steps:
One is installed on the other mistake proofing shifting fork bar of shaft coupling;
Mistake proofing driving lever inside caliper cun 21.5mm;
Steel disc parts riveting ring external diameter 22.1mm, riveting sleeve external diameter 21mm; If when operator manually pulls driving lever handle, in driving lever, cartoon is crossed riveting ring, operator tightens screw by pneumatic torque spanner steel disc parts is connected with crossed joint, and steel disc parts and crossed joint bonding strength are normal;
If driving lever blocks, steel disc parts 90 degree misplace position, stop tightening screw.
Compared with prior art, the invention has the beneficial effects as follows: avoid the artificial misloading of invar chip part to cause steel disc parts and crossed joint bonding strength after screw-driving to reduce bad accident, met shaft coupling erection, its dependable performance, easy to use.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present invention.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
From Fig. 1, Fig. 2: the present invention realizes by following steps:
One is installed on the other mistake proofing shifting fork bar 4 of shaft coupling;
Mistake proofing driving lever inside caliper cun 21.5mm;
Steel disc parts riveting ring 2 external diameter 22.1mm, riveting sleeve 3 external diameter 21mm; If when operator manually pulls driving lever handle, in driving lever, cartoon is crossed riveting ring, operator tightens screw by pneumatic torque spanner steel disc parts 1 is connected with crossed joint 5, and steel disc parts and crossed joint bonding strength are normal;
If driving lever blocks, steel disc parts 90 degree misplace position, stop tightening screw.
The present invention can avoid the artificial misloading of invar chip part to cause steel disc parts and crossed joint bonding strength after screw-driving to reduce bad accident, and operability well meets shaft coupling erection.
