Abstract
The invention provides a dual-tool machining device for machining irregular-shaped external cylinders of pistons. The dual-tool machining device comprises a rail slider; a first tool used for machining external cylinders of piston workpieces and a second tool for machining wear insert rings are fixed to the rail slider and are arranged sequentially along a direction parallel to the centre axis of each piston workpiece; the extension length of the first tool is larger than that of the second tool, and the distance between the first tool and the second tool is larger than the distance from the top surface of the piston workpiece to the bottommost edge of each piston insert ring. By the dual-tool machining device simple in structure, users do not need to switch the tools through a tool switching mechanism frequently during machining, thus machining efficiency and precision are improved.
Description
Technical field
The present invention relates to Piston Machining equipment technical field, refers to especially a kind of Double-blade processing unit (plant) for irregular excircle of piston processing.
Background technology
Piston is the strength member of the internal combustion engine of various vehicles, and its crudy directly affects the performance of vehicle, and particularly the shape line precision of middle-convex and varying ellipse shape periphery is the hugest on end product quality impact.In order to strengthen the structural strength of piston, the piston of many aluminum alloy materials can increase at the annular groove place nearest apart from top the piston abrasion-proof inserted ring of cast iron or cast steel during fabrication.And while carrying out the fine finishining of piston middle-convex and varying ellipse shape periphery in actual production, the adopted cutter that cuts aluminum alloy is not suitable for cutting piston abrasion-proof inserted ring, directly uses one tool sharpening can be caused to cutter sharp wear, greatly reduces cutter life.Therefore, need on smart external cutting device, install 2 or 2 the cutters of above unlike material with respectively machining piston abrasion-proof inserted ring position and remaining part position thereof.Current process equipment adopts some complicated cutter-exchange mechanisms to realize the function that much knives tool is installed more, and this cutter-exchange mechanism exists more problem: the one, and cutter-exchange mechanism is comparatively complicated, forms member many, and reliability is difficult to guarantee, and manufacturing cost is high; The 2nd, there is the error of repetitive positioning accuracy in cutter-exchange mechanism; The 3rd, cutter-exchange mechanism has increased the weight of the motion parts of smart external cutting device (also claiming ellipse generator), and positioning precision, system rigidity etc. is had a negative impact.
Summary of the invention
The object of the invention is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, machining accuracy is high for the Double-blade processing unit (plant) of irregular excircle of piston processing.
For achieving the above object, the present invention adopts following technical proposals: a kind of Double-blade processing unit (plant) for irregular excircle of piston processing, comprise rail piece slide plate, on described rail piece slide plate, be fixed with for the cutter I of piston article Excircle machining and the cutter II of processing for abrasion-proof inserted ring, described cutter I is arranged in order with in the direction parallel with the axis of piston article of cutter II edge, and the length that cutter I leans out is greater than the length that cutter II leans out, the distance between cutter I and cutter II blade is greater than the distance that piston article end face to piston ring carrier descends edge most.
During use, first controlling rail piece slide plate uses cutter I partly to carry out smart Excircle machining to piston article except abrasion-proof inserted ring, now only have cutter I to contact with piston article, cutter II due to lean out length short not with piston article Surface Contact, can not cause interference to the processing of cutter I; Then control moving rail piece slide plate and use cutter II partly to carry out fine finishining to abrasion-proof inserted ring, now the position of cutter I exceeds piston article top and does not contact with piston article, can not cause interference to process.
Further, described cutter I and cutter II are fixed in-orbit on piece slide plate by hold(ing)-down clip.
Preferably, cutter I leans out 2-3mm than cutter II more.This programme can add the operation stroke that as far as possible reduces rail piece slide plate under non-interfering prerequisite in man-hour meeting cutter I and cutter II, accelerates process velocity and precision.
Preferably, cutter I leans out 2mm than cutter II more.
Preferably, cutter I leans out 2.5mm than cutter II more.
Preferably, cutter I leans out 3mm than cutter II more.
The invention has the beneficial effects as follows: utilization of the present invention with the piston article abrasion-proof inserted ring of abrasion-proof inserted ring in apart from the nearest annular groove in top and the less feature of distance, use 2 cutter, abrasion-proof inserted ring part and the cylindrical remainder of the corresponding machining piston workpiece of difference, 2 cutters are arranged in parallel and are separated by a distance along workpiece axial direction, this distance is greater than the distance that piston article end face to abrasion-proof inserted ring descends edge most, and leaning out the certain distance that staggers in length, by cutter arranged in dislocation, and combination is with the design feature of the piston article of abrasion-proof inserted ring, the ingenious Double-blade processing having realized with the piston article of abrasion-proof inserted ring, the present invention is simple in structure, adds and does not need man-hour to use the frequent tool changing of cutter-exchange mechanism to improve working (machining) efficiency and machining accuracy.
