Description
Technical field
The present invention relates to the Machining Technology field, particularly in the engine crankshaft process, be used to detect the cubing and the detection method thereof of its grade heart distance.
In the bent axle process, axial dimension is one of project more rambunctious.Show as: when the wide side margins of finishing shelves was too small, the processing dimension of some axle journal end face did not reach standard-required, produced waste product or unacceptable product; When the wide side margins of finishing shelves was excessive, the emery wheel fillet damaged when causing correct grinding, produced crankshaft fillet and step occurred with the end face transition position, increased emery wheel consumption simultaneously, the reduction grinding efficiency.
The main cause that causes above phenomenon is heat treatment deformation, the wide instability of roughing shelves, axial dimension chain complexity etc.Usually, heat treatment deformation is always unavoidable; The wide instability of roughing shelves also can not all be eliminated mainly by the decision of factors such as cutter apparatus.But the wide eccentric wear of shelves, axial dimension chain complexity can be optimized.
At present, the detection method of domestic and international bent axle processing all is to detect crankshaft thrust face to side of tested axle journal (because of product figure marks like this).Below existing, this detection method covers end:
1, produces the wide eccentric wear of shelves, influence bent axle crudy and reduction emery wheel serviceable life.
Shown in Fig. 7 (is example with the tool wear), in existing batch process roughing, all be to adopt forming tool processing shelves wide, the two sides that the axle journal shelves are wide are disposable to process.And traditional handicraft detects the axial dimension (L among Fig. 7) that only detects a side, the axial location of another side is guaranteed by the wide size of shelves fully, shelves are wide good then good, shelves are wide bad, not detected side or do not have surplus to process, produce unacceptable product and waste product, or the wide eccentric wear of the too big generation shelves of process redundancy, emery wheel was lost efficacy in advance.
And when the processing of carrying out certain gear axial dimension and detection, axial location should be decided by two sides of this axle journal, detecting axial dimension should be as the criterion with the axial dimension (L ' among Fig. 7) of the wide center line of axle journal shelves, only in this way could represent the axial location of two sides.
2, process dimension chain complexity
As shown in Figure 8, traditional processing technology generally all is to detect axial dimension by the mode shown in the axis upper dimension chain among Fig. 8.Adopt this mask method,, certainly lead to a new axial dimension as long as which axle journal is processed.Bent axle is in actual process, and each axle journal is all processed in batches, therefore, processed, the detection of a series of axial dimensions of slight difference is arranged, and must carry out size when adjusting lathe and calculate and change, and processing is got up very complicated.As Fig. 8 top size, a kind of axial dimension of 4 cylinder crankshafts just reaches 14 decimal sizes, be difficult to memory, in basketry, use technology, detect axial dimension, carry out on lathe adjustment between next procedure, be difficult to memory when correcting unacceptable product, convert, mistaken easily.When the opposite size of both direction being carried out the process redundancy adjustment, be easy to do anti-simultaneously.
And control bent axle processing with the detection shelves heart apart from method (mode shown in Fig. 8 axis lower dimension chain) is a kind of processing technology scheme of comparison science, does not put into practice but there is effective cubing at present.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of shelves heart of bent axle axial dimension that detects apart from cubing and detection method thereof, by adopting the shelves heart to detect the axial dimension of the wide center line of axle journal shelves apart from cubing, to realize simplifying the dimension chain in the processing, change the wide eccentric wear of shelves, improve the purpose of bent axle machining precision.
For achieving the above object, technical scheme of the present invention is: bent axle is by left top part and right top tip part sub-support, center line is parallel with coaster direction of motion, coaster links by two rectilinear orbits and flat board, pallet is equipped with in dull and stereotyped bottom, to keep dull and stereotyped level, the scale of grating rule displacement sensor digital readout system is fixed on the flat board, direction is parallel to coaster direction of motion, moving chi links to each other with coaster, it is characterized in that: shelves heart test section is fixed on the coaster, height is contour with crankshaft axis, the position numerical value of shelves heart test section shows by the digital display display screen, like this, horizontal rectilinear motion can be made at dull and stereotyped upper edge rectilinear orbit in coaster and shelves heart test section, and the position moment of shelves heart test section has kept one-to-one relationship with the demonstration numerical value of grating rule displacement sensor digital readout system, by the digital display display screen its numerical value is shown.
The slide of described shelves heart test section links to each other with coaster is fastening by 4 bolts, 2 register pins, abrasion-proof backing block links to each other with slide is fastening by 2 bolts, with cooperating of forming of sliding sleeve be that micron order is slidingly matched, cover plate links to each other with slide is fastening by 6 bolts, with cooperating of forming of sliding sleeve be that little gap is slidingly matched, sliding sleeve is installed in the rectangle square hole of being made up of cover plate, liner plate, slide with sliding matching mode; The right-hand member of sliding sleeve is equipped with big handle, fixes by seccotine; The end is that the slide bar with symmetrical inclined-plane is contained in the rectangular through-hole of sliding sleeve, for micron order is slidingly matched, the slide bar center line is perpendicular to rectilinear orbit, the right-hand member of slide bar is equipped with miniature lever with transition fit, is connected by the straight pin transition fit, between miniature lever and sliding sleeve stage clip is housed, in big handle and the miniature lever hexagon socket head cap screw is housed, by set nut locking, hexagon socket head cap screw is fixedlyed connected with miniature lever, is slidingly connected with big handle; 2 rotating rocking arms are housed respectively in the open slot of sliding sleeve left end, connect by 1 little clearance fit of straight pin respectively, the gauge head that contacts with the wide two sides of axle journal shelves is equipped with when being used to measure by the wringing fit mode respectively in two rocker head portions, the gauge head head is the hemisphere sphere, connect by small extension spring between two rocking arms, the spherical boss of two rocking arm medial surfaces contacts with two inclined-planes of slide bar respectively, under the effect of small extension spring pulling force, the semi arch of two rocking arms projection contacts with two symmetrical inclined-planes of slide bar front end constantly.Like this, shelves heart test section total energy when measuring guarantees to aim at the wide center line of each axle journal shelves.
Operating mechanism of the present invention is big handle and miniature lever.Big stick control sliding sleeve and the part above the sliding sleeve and is slided before and after doing with respect to slide, so that can make sliding sleeve enter the wide detection of shelves and withdraw from shelves and make move left and right after wide; Miniature lever is being handled the relative motion between slide bar and the sliding sleeve, and slide bar is being controlled two rocking arms and rotated by the front end inclined-plane, thereby reaches the purpose that the control gauge head is measured or do not measured.During measurement, miniature lever pushes away and is maintained to reading forward and only finishes, and when not measuring, release handle gets final product.
Position-limit mechanism is big handle, miniature lever, hexagon socket head cap screw, set nut.Extreme position by the THICKNESS CONTROL slide bar of set nut is pushed ahead has also just determined the wide degree of measured maximum; Regulate slide bar extreme position backward by hexagon socket head cap screw, generally transfer to two gauge heads and do not protrude the sliding sleeve two sides and get final product.
The measuring principle of shelves heart test section:
Slide bar can slide in sliding sleeve, and stroke is 0 ~ d(such as Fig. 3, Fig. 4); Measure-alike, the installation symmetry of two rocking arms, two gauge heads.Because of rocking arm on the inclined-plane of two symmetries that always abut against slide bar under the effect of small extension spring, so the measuring point width B (as Fig. 4) of two gauge heads is also followed the variation of slider bar travel and is changed, by B ~ B ' (as Fig. 5), and the center line of width B all the time with the central lines of slide bar.To Fig. 6, can prove by calculating, in the contacted scope in the inclined-plane of rocking arm and slide bar:
Equation 1:B/2=h/2+r2+b ﹡ sin(A-D)
Equation 2:L=a ﹡ cosD-r1 ﹡ sinC+(h/2-r1 ﹡ cosC-a ﹡ sinD)/tgC
In the formula: D is an independent variable, and B, L are dependent variable, and all the other are constant.
Detection method of the present invention is for controlling bent axle processing with the method that detects the wide center line of each grade of bent axle, detection method is as follows:
A: load onto bent axle, central aperture top part in a left side and right top part with bent axle hold out against bent axle with suitable dynamics;
B: open the digital display power switch, observe the digital display display screen and show normal;
C: pull back big handle, guarantee that the sliding sleeve head bumps less than bent axle, movable block is to bent axle thrust shelves;
D: promote big handle to sliding sleeve head and contact with this axle journal cylindrical;
E: promote miniature lever forward, drive slide bar and push ahead, two inclined-planes of slide bar drive two rocking arms and expand outwardly simultaneously, at this moment, gauge head is with grade certain wide contacts side surfaces and produce thrust, coaster is moved, when two gauge heads all touch two sides of axle journal along rectilinear orbit, wide center line of these axle journal shelves and slide bar central lines, the stressed of coaster both sides equates that coaster has been reserved the position and can't have been moved, at this moment, press reset switch on the digital display display screen, screen display numerical value is 0;
F: unclamp miniature lever, under the thrust of stage clip, the relative sliding sleeve of slide bar slides backward, and two rocking arms are inwardly regained under the effect of small extension spring simultaneously, and two gauge heads break away from and the axle journal contacts side surfaces; When slide bar slides to the enlarged head of hexagon socket head cap screw and the distance of handle counterbore table top is 0 greatly, the returned original position of slide bar, simultaneously, two gauge heads have also retreated in the two sides of sliding sleeve, retract big handle to the appropriate location, to guarantee that not running into bent axle when next step movable block gets final product, and moves to coaster the axle journal position that the next one will be measured again;
G: C, D, E carry out set by step successively, when having operated " coaster has been reserved the position and can't have been moved ", no longer carry out clear operation, but from the digital display display screen reading, record numerical value, the numerical value of this moment is the axial distance at thrust shelves center to the wide center of this grade shelves; And then carry out the operation of step F;
H: repeat set by step that G carries out, measure the axial dimension of the wide center line of each axle journal shelves to thrust shelves center line successively, measurement finishes, and with each standard value contrast, whether the bent axle axial dimension is qualified as can be known, unloads bent axle.
The present invention is by adopting the shelves heart apart from cubing, detect the axial dimension of the wide center line of axle journal shelves of the axial location of representing two sides, slightly, adjusting lathe during finishing makes the wide center line value of axle journal shelves consistent with standard figures, like this, no matter how shelves wide the variation, the surplus on both sides is always uniform, has avoided the wide eccentric wear of shelves, and makes process dimension chain simplify.
The present invention compared with prior art has the following advantages:
1, can effectively improve emery wheel and take turns serviceable life.
In crankshaft grinding, the emery wheel more than 80% does not grind bent axle and grinds off, but trim with diamant.Because the main cause that emery wheel lost efficacy during crankshaft grinding is emery wheel fillet and side transition position rust or damage, in case rust or damage just have to the good part crushing on the same horizontal line is fallen.Therefore, the surplus of axle journal side before should reducing as far as possible to grind on technology is to improve emery wheel utilization factor and grinding efficiency.
The present invention can detect slightly, the axial dimension of the wide center line of finishing shelves, and when adjusting lathe, thick, finishing is all by this dimensioned, grinding, like this, no matter how shelves wide a variation, always the surplus on both sides is uniform, big surplus one side is damaged the emery wheel fillet when having avoided the wide eccentric wear of shelves.Reduced T/2 as (L '+the new cutter of B/2) among Fig. 7 than the variation of (the new cutter of L+B), meaned under identical situation, can reduce the spacious and comfortable amount T/2 of shelves, suitably reduced the emery wheel loss and improve grinding efficiency.The wide variation of roughing shelves of general bent axle (removing especially big and special little) is between 0.1 ~ 0.5 millimeter (by the decision of equipment class) generally, if by average 0.3 millimeter calculation, then can reduce 0.15 millimeter of the spacious and comfortable amount of roughing shelves; The shelves wide-wheel grinding of general bent axle is cut surplus between 0.2 ~ 0.6 millimeter, therefore, can reduce 0.15 millimeter surplus, will help to improve wheel life.
2, simplified process dimension chain.
The change of detection method of the present invention makes process dimension chain simplify.Fig. 8 is the comparison of process dimension chain of two kinds of detection methods of certain four-cylinder bent axle four procedure.The shelves heart of lower part is apart from detecting dimension chain, only 7 sizes, 4 integral multiple size numerical value, no matter be roughing, semi-finishing, finishing, all have only this 4 size numerical value, both be convenient to memory, come into plain view, mistaken direction when being unlikely to adjust again simultaneously, obtains perfect unity with the lathe of modern digital display class.Therefore, technology obtains simplification, processing becomes convenient.
