Abstract
The invention belongs to a technology for processing and manufacturing a crankshaft of a diesel engine of an internal combustion railway locomotive, and provides a drilling jig aidauxiliary device for a crankshaft flange hole of a diesel engine. The drilling jig aidauxiliary device comprises a bottom plate (1), a transitional sleeve (2), a positioning screw (5), a plurality of flange hole rapid-changing sleeves (3) and a plurality of lifting ring screws (4); wherein the bottom plate (1) is provided with a plurality of through holes for installation of the transitional sleeve along the circumference; the flange hole rapid-changing sleeves (3) are divided into three types: fine drilling sleeves, crude hinging sleeves and fine hinging sleeves; and two lifting ring screws (4) are adopted and are fixed on two corresponding sides of the bottom plate (1). The drilling jig aidauxiliary device for the crankshaft flange hole of the diesel engine has the advantages of reasonable design structure and simpleness and convenient convenience in use, the manufacturing accuracy of the crankshaft of the diesel engine of the internal combustion locomotive can be achieved, and the working efficiency can be improved greatly.
Description
Technical field
The invention belongs to Railway Diesel Locomotive Engine Crankshaft Machining manufacturing technology, the main drill jig servicing unit that proposes a kind of crankshaft of diesel engine flange hole, in order to solve the problems of drilling of DF8B type locomotive crankshaft of diesel engine output flange hole, make it to satisfy the specification requirement of product.
Background technology
DF8B diesel engine of diesel locomotive bent axle is the key component of diesel locomotive, belongs to thin and long shafts, complex structure, accuracy of manufacture height.Its flange hole dimensional tolerance is that 0.027mm, position degree are φ 0.05mm, and because the bent axle total length surpasses 4 meters, the cumulative errors of machine tool can not satisfy specification requirement.The frock that this just requires to design a kind of auxiliary manufacturing satisfies the demand of the manufacturing process of high-precision flange hole.
Summary of the invention
The objective of the invention is to propose a kind of drill jig servicing unit of crankshaft of diesel engine flange hole, can improve the product accuracy of manufacture and operating efficiency.
The present invention adopts following technical scheme for finishing above-mentioned purpose:
A kind of drill jig servicing unit of crankshaft of diesel engine flange hole, described drill jig servicing unit include base plate, spacer shell, dog screw, flange hole quick change cover and lifting bolt; Have circumferential a plurality of in order to the through hole of spacer shell to be installed on the described base plate; Described spacer shell be the through hole on the corresponding base plate arrange a plurality of; Each described spacer shell is fixed in the corresponding through hole; Described flange hole quick change cover is three kinds: smart drill bushing, thick hinge cover and finish ream cover; Described smart drill bushing, thick hinge cover and finish ream and be enclosed within different time and mutually replace consist of described smart drill bushing or thick hinge cover or finish ream cover and cooperate with described spacer shell and process the flange pore structure; Described lifting bolt is two, is fixed on the corresponding both sides of base plate.
Corresponding each the flange quick-changing cover of described dog screw arranges.
Described flange quick-changing puts has the positioning boss that cooperates for dog screw.
Have on the described base plate in order to the groove relative with crankshaft flange cylindrical groove.
The present invention is in use take bent axle body seam and flange excircle groove as benchmark.Guarantee the accuracy of manufacture of flange hole.
The drill jig servicing unit of a kind of crankshaft of diesel engine flange hole that the present invention proposes, it is reasonable to have a project organization, uses simply, convenient, can satisfy the diesel engine of diesel locomotive bent axle accuracy of manufacture, has improved greatly operating efficiency.

The specific embodiment
The example that provides by reference to the accompanying drawings is illustrated structure of the present invention.
As shown in Figure 1 and Figure 2: a kind of drill jig servicing unit of crankshaft of diesel engine flange hole, described drill jig servicing unit include base plate 1, spacer shell 2, dog screw 5, flange hole quick change cover 3 and lifting bolt 4; In conjunction with Fig. 3, Fig. 4, have circumferential a plurality of in order to the through hole of spacer shell to be installed on the described base plate 1; In conjunction with Fig. 5, Fig. 6, described spacer shell 2 be the through hole on the corresponding base plate 1 arrange a plurality of; Described spacer shell 2 is high accuracy wear-resistant sleeves; Each described spacer shell 2 is fixed in the corresponding through hole; Described dog screw 5 corresponding each flange quick-changing cover 3 arrange; Has the positioning boss that cooperates for dog screw 5 on the described flange quick-changing cover 3; It is three kinds in conjunction with the described flange hole quick change of Fig. 7, Fig. 8 cover 3: smart drill bushing, thick hinge cover and finish ream cover; Described smart drill bushing, thick hinge cover are the wear-resisting quick change cover of high accuracy of three kinds of different operations with finish reaming cover, by the one by one fast assembling of conversion and diverse location spacer shell, the positioning boss that utilizes quick change cover is fixing with its Relatively orientation screw, realizes expanding, the purpose of the manufacturing of hinge, bore hole difference processing technologys; Described lifting bolt 5 is two, is fixed on the corresponding both sides of base plate 4.
Described dog screw 5 corresponding each flange quick-changing cover 3 arrange.
Have on the described base plate 1 in order to the groove relative with crankshaft flange cylindrical groove.
The present invention is in use take bent axle body seam and flange excircle groove as benchmark.Guarantee the accuracy of manufacture of flange hole.
Concrete using method: with the lifting bolt 4 of rope vertical lifting drill jig, its position that groove is arranged is surpassed, the base plate 1 endoporus center and the crankshaft output end that are equipped with spacer shell 2 and dog screw 5 is contour, careful and the seam assembling applying with the base plate endoporus, a spacer shell with smart drill bushing and base plate assembles first, rotate to dog screw gear and stop compacted position, can finish flange hole operation of counterboring.Smart drill bushing and the assembling of next position spacer shell are taken off in convolution fast, repeat above-mentioned each action, repeatedly finish this manufacturing process 9 times; With thick hinge cover, finish ream external member and repeat the action of above-mentioned operation, can finish crankshaft output end flange hole manufacturing process, guarantee the flange hole accuracy of manufacture.
