Abstract
The invention discloses a kind of processing method of pivoted arm frame on floor type boring and milling machine, comprise the following steps：Feasibility analysis is carried out, expands machining tool scope, and to expand machining tool scope, it is necessary to increase clamping apparatus on the basis of original facing head；Design and produce applicable fixture：Common knife bar is solid medium carbon steel or the quenched bar of steel alloy, but boring bar exceeds facing head outer diameter 500mm, it is excessive to process diameter, weight is eccentric, and linear velocity is high, it is also easy to produce oval and chatter mark, it causes processing quality unqualified, compares through analysis, careful selection seamless steel pipe makees knife bar, to mitigate weight, rigidity is improved；After increasing fixture, facing head eccentricity, inertia increase, and cutter hub is made by long 1200mm, and tail end design counterweight makes facing head balance movement；Cutter is using the white just knife processing at a high speed of superhard matter.The invention has the advantages that expanding the range of work of common floor-type milling ＆ boring machine, time branch is saved for enterprise, throws a sprat to catch a herring for machine tool and provides example.
Description
Technical field
The present invention relates to technical fields of mechanical processing, are specifically a kind of processing method of pivoted arm frame on floor type boring and milling machine.
Background technology
Pivoted arm frame (right big gun, left big gun) is the important part in iron and steel enterprise's clay gun device, its big and heave is generally up to 5-
It is 6 meters, wide up to more than 1 meter, to weigh 6-7 tons up to more than 2 meters, it is mostly welding structural element, in addition to processing multiple faces, shares at 4
The aperture of 18 kinds of sizes will process, wherein there are two types of diameter 1937 × 0.5, roughness 12.5,1927 × 9.5, roughness 1.6
Size considerably beyond the range of work of common boring and milling machine, cannot complete processing under normal circumstances.Certainly, other big
It can be machined in type equipment or machining center, but suitable large scale equipment or machining center do not grow on trees,
Often Distant water cannot quench present thirst, and time and tide wait for no man, and trouble of round transporting, and traffic expense processing charges are high, increases establishment expense spending.
The content of the invention
In order to solve prior art problem, the present invention provides a kind of processing method of pivoted arm frame on floor type boring and milling machine, it
The processing request of pivoted arm frame can be completed on T69160D floor-type milling ＆ boring machines, saves time branch.
In order to achieve the above object, the technical scheme is that, a kind of processing side of pivoted arm frame on floor type boring and milling machine
Method comprises the following steps：
A, study the countermeasure, carry out feasibility analysis, find the key that processing can be completed on this lathe：Confirmation will be completed
Processing, it is impossible by original facing head, it is necessary to expand machining tool scope, and to expand machining tool scope, it is necessary in original
Having increases clamping apparatus on the basis of facing head；
B, applicable fixture is designed and produced：Common knife bar is the quenched bar of solid medium carbon steel or steel alloy, but boring
For bar beyond facing head outer diameter 500mm, processing diameter is excessive, and weight is eccentric, and linear velocity is high, is also easy to produce oval and chatter mark, causes to add
Work is off quality, compares through analysis, careful selection152 × 32, material is that the seamless steel pipe of Q345 makees knife bar, to mitigate weight
Amount improves rigidity；
C, facing head balance is ensured：After increasing fixture, facing head eccentricity, inertia increase, and cutter hub is pressed long 1200mm systems
Make, tail end design counterweight makes facing head balance movement；
D, cutter is selected：Using 20 × 20 × 200 superhard matter white just knife processing at a high speed；
E, clip pivoted arm is rack-mounted, gradually machined by low requirement is schemed.
The invention has the advantages that not only expanding the range of work of common floor-type milling ＆ boring machine, but also saved for enterprise
Time, funds are saved, thrown a sprat to catch a herring for machine tool and provide example.
Description of the drawings
Fig. 1 is pivoted arm frame schematic front view.
Fig. 2 is Fig. 1 sectional views.
Fig. 3 is present clip schematic front view.
Fig. 4 is present clip schematic top plan view.
In figure, 1 seamless steel pipe knife bar, 2 tool-post structures, 3 with facing head connecting seat.
Specific embodiment
Below in conjunction with attached drawing, the present invention is further described.
As shown in Figures 1 to 4, the processing method the invention discloses a kind of pivoted arm frame on floor type boring and milling machine, including with
Lower step：
A, feasibility analysis is carried out, finds the key that processing can be completed on this lathe：Confirmation will be completed to process, and rely on
Original facing head is impossible, it is necessary to expand machining tool scope, and to expand machining tool scope, it is necessary in original facing head
On the basis of increase clamping apparatus；
B, applicable fixture is designed and produced：Common knife bar is the quenched bar of solid medium carbon steel or steel alloy, but boring
For bar beyond facing head outer diameter 500mm, processing diameter is excessive, and weight is eccentric, and linear velocity is high, is also easy to produce oval and chatter mark, causes to add
Work is off quality, compares through analysis, careful selection152 × 32, material is that the seamless steel pipe of Q345 makees knife bar, to mitigate weight
Amount improves rigidity；
C, after increasing fixture, facing head eccentricity, inertia increase, and cutter hub is made by long 1200mm, tail end design counterweight,
Make facing head balance movement；
D, the selection of cutter：Using 20 × 20 × 200 superhard matter white just knife processing at a high speed；
E, clip pivoted arm is rack-mounted, gradually machined by low requirement is schemed.
The fixture cutter of the present invention is loaded onto into facing head, you can complete the processing to pivoted arm frame.
The design design of present clip cutter is crucial, and thinking is correct, and fixture Tool Design is reasonable, you can completes to be processed
The processing of part needs, this expands the range of work for other machine tools and has guided direction.
