Abstract
The utility model relates to a guiding tool for the rear oil seal of a diesel engine. The guiding tool solves the problems of oil seal deformation and lip scratching which cause loss of oil sealing function in the prior assembly tool. The guiding tool comprises a guiding cone frustum, wherein the small end of the guiding cone frustum is axially connected with a handle while the middle part of the large end thereof is axially connected with a coaxially positioning column; and a positioning pin hole is formed on a large end face of the guiding cone frustum outside the positioning column. The guiding tool is made of nylon. In the utility model, the guide surface of the guiding tool adopts a circular conical surface, and the handle is arranged behind the guide surface. Therefore, scratches and damages to the lip of the oil seal due to the shrinkage of the rear oil seal can be avoided, and the operation is easy; the guiding tool is made of nylon 1010 which is light and durable; the structure is simple; the manufacture cost is lower; neither burr nor parting-line flash can be caused; the rear oil seal is protected from scratching; and the oil sealing effect of the rear oil seal is ensured.
Description
Technical field
The special-purpose steering tool of protection oil seal lip when the utility model relates to the Diesel Engine Complete Machine assembling.
Background technology
Development with the work diesel technology, people are having requirements at the higher level to the diesel engine product aspect structure, performance, quality, reliability, the service, steering tool (Fig. 1) before this utility model is made of the 45# steel, and poor, heavy, impracticable and easy scratch oil sealing lip sheet leads.In the assembling process, people often ignore this detailed problem, cause oil sealing distortion, the scratch of lip sheet, cause the oil sealing afunction, and have a strong impact on the oil sealing effect of oil sealing.Finally cause seal failure, produce seepage.
Summary of the invention
For oil sealing distortion, the scratch of lip sheet that overcomes existing assembly tool existence, the problem that causes the oil sealing afunction, the utility model provides a kind of diesel engine Rear oil seal steering tool.
Diesel engine Rear oil seal steering tool comprises the guiding frustum of a cone, and the small end of the described guiding frustum of a cone is axially connecting handle, and its big end axially middle part is connecting coaxial positioning cylinder, and the outer guiding frustum of a cone large end face together of positioning cylinder is provided with a location pin-and-hole.
The utility model steering tool spigot surface is taked taper seat, and the back jug can be avoided because of the contraction of Rear oil seal the scuffing of oil sealing lip sheet being damaged easy operating; This steering tool material is a nylon 1010, and lightly durable, simple in structure, manufacturing cost is lower, and can not produce burr and overlap, can not scratch Rear oil seal, guarantees the oil sealing effect of Rear oil seal.
Diesel engine Rear oil seal steering tool should be by the alignment pin location of bent axle major part ring flange when operation, be fixed on the ring flange, hold the Rear oil seal seat that has installed oil sealing then properly, oil sealing hole is aimed at the other end of erecting tools, and it is lentamente that the Rear oil seal seat is close toward erecting tools, when sensation oil sealing lip sheet touches erecting tools, the operator should slow down firmly, set upright the Rear oil seal seat, and keep lip sheet endoporus concentric with the axle of erecting tools as far as possible, one side is rotated the Rear oil seal seat, one side pushing away inward gently, be combined on the axial plane of bent axle major part ring flange by the erecting tools complete hold until oil sealing lip sheet till, adjust mounting hole site at last, screw bolt and get final product.Obviously improve through improving self-contained quality, reduced maintenance and the replacing in the process, reduced the waste of part, this instrument can be promoted in all the other products.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model user mode figure.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, diesel engine Rear oil seal steering tool comprises the guiding frustum of a cone 4, the small end of the guiding frustum of a cone 4 is axially connecting handle 3, and its big end axially middle part is connecting coaxial positioning cylinder 2, and the guiding frustum of a cone large end face of positioning cylinder 2 peripheries is provided with a location pin-and-hole 1.
The steering tool material is a nylon 1010.
Referring to Fig. 2, the bent axle major part ring flange 5 of during assembling the positioning cylinder 2 of this steering tool being packed into, and insert dowel hole 1 by the bent axle alignment pin and realize the location, hold the Rear oil seal seat that has installed oil sealing then properly, oil sealing hole is aimed at the oil sealing guiding frustum of a cone 4 of erecting tools, and it is lentamente that the Rear oil seal seat is close toward erecting tools, when sensation oil sealing lip sheet 6 touches the guiding frustum of a cone 4, the operator should slow down firmly, set upright the Rear oil seal seat, and keep lip sheet endoporus concentric as far as possible with the axle of the guiding frustum of a cone 4, one side is rotated the Rear oil seal seat, one side pushing away inward gently, be combined on the axial plane of bent axle major part ring flange by 4 complete holds of the guiding frustum of a cone until oil sealing lip sheet 6 till, adjust mounting hole site at last.Finally this steering tool is taken out and get final product.
Claims (2)
