Abstract
A benchmark deviation compensation type processing method used for a box or shell part comprises the steps as follows: firstly, the box or shell part is positioned and clamped on CNC (computer numerical control) machining equipment with a transition benchmark serving as a positioning benchmark; secondly, actual measurement distance values of a transition benchmark zero relative to a main positioning benchmark zero are detected, and difference values between each actual measurement distance value and a corresponding theoretical distance value are calculated respectively; thirdly, a coordinate value of the transition benchmark zero is corrected through the difference values to form a corrected transition benchmark zero; and fourthly, the corrected transition benchmark zero is taken as a workpiece coordinate system zero to process a to-be-processed structure on the box or shell part.

Description
Technical field
The present invention relates to a kind of casing or shell part, for example the processing method of engine cylinder-body particularly, relates to the compensation processing method of datum drift that is used for casing or shell part in a kind of casing or the shell part process.In addition, the invention still further relates to a kind of compensation system of processing of datum drift that is used for casing or shell part for the above-mentioned processing method of realization.
Background technology
In machining, often need machining box or shell part, for example engine cylinder-body, engine cylinder cover, oil sump, crankcase, gear hub etc., the processing of these parts generally has a general main location benchmark, in process, should adopt main location benchmark that casing or shell part are positioned clamping as much as possible, so that the location benchmark in the machining process keeps unified, reduce mismachining tolerance.But, in casing or shell part process, can occur some structures to be processed inevitably and be not suitable for adopting the main situation that benchmark positions of locating, for example structure to be processed need be formed on the main location basal plane of main location benchmark, often needs to adopt this moment transition location benchmark to position clamping.In order to say something, below mainly describe with the example that is processed as of engine cylinder-body.
Engine cylinder-body is formed with a plurality of installed surfaces and installing hole as the main installation carrier of engine component on it.Engine cylinder-body relates to the processing technology of relative complex in process, work flow roughly is as follows: processing → cylinder hole heavy boring, the honing processing → finish-milling top plane → finished product of plane, roughing top, bottom surface → fine finishining location benchmark (being bottom surface, two dowel holes) → thick fine finishining front and rear end → boring first time cylinder hole, the hole of milling watt seat two sides etc. → each deep hole machining → six faces of boring second time cylinder hole → cylinder body, boss etc.Known ground, in the process of engine cylinder-body, follow six point location principles, ideally, it should adopt one side two pins to position, namely should utilize two alignment pins on cylinder body bottom surface (oil sump installed surface) and the bottom surface to locate benchmark as the master, finish most of roughing operation and whole finishing step of cylinder body, this localization method has guaranteed theoretic six point location principles, and namely plane 3 points, straight pin 2 points, rhombus pin are a bit.
But, the work flow of above-mentioned engine cylinder-body, can there be variation in different manufacturers according to the production practices situation of self.At large, because the engine production producer of specialty has the outside cooperation producer of self mostly, the part manufacturing procedure (especially roughing operation) of engine cylinder-body is usually finished by outside cooperation producer, this make by main location benchmark finish most of roughing operation of cylinder body and all finishing steps have difficulties.
Particularly, for example, the applicant has two engine cylinder-body production lines at present, every engine line all adopts machining center (the Star500 type horizontal Machining centers of German Cross Huller company for example, it is four-axle linked design, and versatility is stronger) and special purpose machine tool carry out combinations produce.Machining center is responsible for the roughing of some underloadings, and as drilling and tapping etc., special purpose machine tool is responsible for the processing of key position, as semifinishing and the fine finishining at positions such as bent axle, cylinder hole, end face.Wherein, the heavily loaded roughing of engine cylinder-body is all carried out the processing of outer committee by external coordination producer, as the roughing of cylinder hole, crankshaft hole and open grade face roughing etc.For fear of the benchmark transformed error, the main project of outer committee adds man-hour used location benchmark and is mainly the main location benchmark of known engine cylinder-body processing, be two dowel holes on cylinder body bottom surface (being the oil sump installed surface) and the bottom surface, thereby two dowel holes on cylinder body bottom surface and the bottom surface also need the processing of outer committee.But, engine cylinder-body bottom is except bottom surface and dowel hole need be processed, also usually need to process atomizer installing hole, oilhole etc., externally cooperate after producer sends to the cylinder body semi-finished product, hole on these cylinder body bottom surfaces need be processed by machining center voluntarily by the applicant, this must relate to engine cylinder-body work in-process positioning and clamping in the heart, owing to need the hole of processing to be positioned on the bottom surface of engine cylinder-body, therefore when these projects of processing, just be difficult to adopt the main location benchmark of above-mentioned normal " one side two pins ".
For addressing the above problem, the general practice is that other side on engine cylinder-body forms a transition baseline, for example form the false boss as the location basal plane in the exhaust side side of engine cylinder-body, position with this transition baseline then, process the project of engine cylinder-body bottom, for example oilhole etc.In this case, owing in fact adopt transition baseline to position, the unactual positioning action that plays of main location benchmark (i.e. " plane and two pits ") that forms on the cylinder body.
Particularly, suitably referring to shown in Figure 1, for example work in-process adds man-hour in the heart, engine cylinder-body clamps by the anchor clamps location as the actual location benchmark with transition baseline, the transition baseline that constitutes on setting element on the anchor clamps and the engine cylinder-body that the basal plane of transition baseline forms is expressed as WZP1 zero point, and lathe coordinate system is expressed as MZP zero point.Work in-process heart B axle (being rotatable platform) corner is 180 when spending, and workpiece bottom is towards machine tool chief axis, suppose this moment WZP1 on lathe X, Y, three directions of Z with respect to the distance of lathe coordinate system MZP at zero point be respectively 212.5mm, 380mm ,-83mm.In this case, suppose and need bore a hole in the cylinder body bottom surface that the hole number is H6001, this hole is respectively-255.5mm, 235mm apart from transition baseline WZP1 at zero point on X, Y both direction, and the aperture is 383mm in the distance of Z direction distance W ZP1.At this moment, the conventional machining process that work in-process is processed in the heart is specific as follows, for helping to understand the procedure that has provided the machining center employing, wherein machining center adopts general Simens (Siemens) digital control system (for those skilled in the art knownly, be the note language of specific procedure statement behind the branch in the following procedure, only help to read debugging routine, do not carry out for machining center):
The first, the coordinate system when machining hole H6001 is set is displaced to transition baseline WZP1 at zero point by lathe MZP at zero point with coordinate zero point.
$P_UIFR[1, X, TR]=212.5; WZP1 and MZP differ 212.5mm at directions X
$P_UIFR[1, Y, TR]=380; WZP1 and MZP differ 380mm in Y-direction
$P_UIFR[1, Z, TR]=-83; WZP1 and MZP differ 83mm in the Z direction
$P_UIFR[1, B, TR]=0; WZP1 is consistent with MZP B shaft angle degree
The second, call the coordinate system that sets with G54, and under this coordinate system machining programming.
G0 G54 X-255.5 Y235 M3 D1; Main shaft moves on to the position of X-255.5 Y235 fast
G0 Z=383+3; Main shaft moves on to from the position of aperture 3mm fast along the Z axle
G1 Z=383-10; Boring, hole depth 10mm
G0 Z600; The Z axle falls back on home fast
By conventional machining process as can be seen, the processing technology that this is traditional and system of processing thereof are in the following process to above-mentioned cylinder body, the actual location benchmark that adopts is transition baseline, also is transition baseline zero point of forming with this transition baseline in process as workpiece coordinate system zero point.But, as mentioned above, the main roughing operation of engine cylinder-body and whole finishing step should adopt main location benchmark to process as the location benchmark, described main location benchmark is generally selected according to the design basis of engine cylinder-body, therefore the described main benchmark of locating can be similar to the design basis of thinking engine cylinder-body, and transition baseline only is the interim benchmark that adopts for ease of processing in the process.Known ground, in mechanical processing process, should follow unifying datum and datum coincidence principle, should unify to adopt main location benchmark (i.e. above-mentioned " one side two pins ") as processing location benchmark, with the error of avoiding adopting different location benchmark to bring in the engine cylinder-body process as far as possible.Under the situation that adopts above-mentioned transition baseline as the location benchmark, because the mismachining tolerance of transition baseline, the clamping error when adopting transition baseline to position, will inevitably cause having deviation between transition baseline and the main location benchmark, namely produce not coincidence error of so-called benchmark, this can have influence on the machining accuracy of the relevant processing project of engine cylinder-body bottom surface, thereby cause the machining accuracy of engine cylinder-body not high, when serious even cause engine cylinder-body to become waste product.
Defective in the above-mentioned machining process is prevalent in the process of casing or shell part, and is not limited to above-mentioned engine cylinder-body.In view of this, need design a kind of processing method and system of processing thereof for casing or shell part, to overcome the above-mentioned defective of prior art.

At first need to prove, the invention provides a kind of processing method at casing or shell part, the major technique design of this processing method is when adopting the structure of transition baseline location machining box or shell part, the deviate of the main location benchmark of casing or shell part and transition location benchmark is compensated in the workpiece coordinate system of setting up zero point with transition location benchmark, with the machining accuracy of raising casing or shell part.Need to prove for this reason, one, the box parts of indication of the present invention, mainly be that outer shape is hexahedron or is hexahedral workpiece substantially and (but do not get rid of the structure that has hole and so on these box parts, cylinder hole for example), shell part mainly is the open workpiece that is used for realizing the cover cap function of a side, understands the present invention for helping those skilled in the art, below mainly is that example is described with the engine cylinder-body; They are two years old, although mainly be that example illustrates processing method of the present invention with the machining center in the explanation hereinafter, but be apparently for those skilled in the art, the technical conceive of processing method of the present invention can be applied on the various suitable numerically controlled processing equipments equally, for example numerical control drilling machine etc.Therefore, protection scope of the present invention should not be limited to be applied to machining center.
The basic embodiment of processing method of the present invention is below at first described, be the preferred embodiment that example is more specifically described processing method of the present invention then with the machining center, be to help those skilled in the art to understand technical scheme of the present invention in the description process, with some basic process principle and the concepts in some machined fields of additional disclosure.The compensation system of processing of datum drift for casing or shell part of the present invention is described on this basis.
Describing for clear, below is that engine cylinder-body 1 is that example is described with described casing or shell part mainly.Referring to Fig. 1 to shown in Figure 6, wherein the size that shows among Fig. 2 to Fig. 5 only be hereinafter described Δ X, Δ Y and the illustration size of Δ Z etc., do not constitute limiting the scope of the invention.Be formed with main location benchmark and transition baseline on the described engine cylinder-body, wherein, described processing method comprises the steps: first step S101, with described transition baseline as the location benchmark with described cylinder body 1 positioning and clamping to numerically controlled processing equipment, the transition baseline WZP1 at zero point that described transition baseline forms is respectively Δ X, Δ Y and Δ Z with respect to main location benchmark WZP2 at zero point theoretical distance value along X-axis, Y-axis and Z-direction in the lathe coordinate system of described numerically controlled processing equipment that described main location benchmark forms; The second step S201, under the state of described cylinder body positioning and clamping, detect described transition baseline WZP1 at zero point and be respectively δ X, δ Y and δ Z with respect to described main location benchmark WZP2 at zero point measured distance value along X-axis, Y-axis and Z-direction in described lathe coordinate system, and calculate difference φ X, δ Y and the difference φ Y between the Δ Y and the difference φ Z between δ Z and the Δ Z between δ X and the Δ X respectively; Third step S301, revise described transition baseline X-axis, Y-axis and the Z axial coordinate value of zero point in described lathe coordinate system respectively to form the transition baseline zero point of revising by each described difference φ X, φ Y and φ Z, the transition baseline zero point of this correction and described main location benchmark WZP2 at zero point distance value along X-axis, Y-axis and Z-direction in described lathe coordinate system equal described theoretical distance value Δ X, Δ Y and Δ Z respectively; The 4th step S401 processes the structure of required processing on the described engine cylinder-body zero point zero point as the workpiece coordinate system of described engine cylinder-body with the transition baseline of described correction.
The basic embodiment of above-mentioned processing method has embodied basic fundamental design of the present invention, although relatively easily understand know-why or the concept that above-mentioned basic embodiment relates to for those skilled in the art, but for helping those skilled in the art more profoundly to understand technique scheme, below some know-whies and concept that above-mentioned basic embodiment is related to describe.
First, processing method of the present invention at be the continuation processing (being that processing object is the engine cylinder-body semi-finished product that formed main location benchmark and transition location benchmark) of engine cylinder-body, especially at the following process of the dependency structure on the engine cylinder-body bottom surface, for example the atomizer installing hole on the engine cylinder-body bottom surface, oilhole etc., that is to say, form main location benchmark on this engine cylinder-body, and also formed transition baseline for the following process of carrying out dependency structure.With regard to the processing of engine cylinder-body, to those skilled in the art apparently, main location benchmark generally can be that engine cylinder-body is through accurately machined bottom surface and two dowel holes that are formed on this bottom surface.Because in the machined field, sometimes when some structures of processing, be unsuitable for adopting main location benchmark, thereby form transition baseline at engine cylinder-body, for example owing to the atomizer installing hole on the engine cylinder-body bottom surface, oilhole etc. are formed on the engine cylinder-body bottom surface, obviously be difficult to this moment adopt the dowel hole on bottom surface and the bottom surface to process as the location benchmark, introduced transition baseline for this reason.For those skilled in the art, transition baseline can have various forms, as long as follow six point location principles, for example can form six false boss faces at the exhaust side of engine cylinder-body in the present invention, three false boss faces in these six false boss faces are in a plane (forming three-point fix when contacting with the setting element of jig), two false boss faces are in a plane (forming two point locations when contacting with the setting element of jig), another false boss face is in another plane (forming a point location when contacting with the setting element of jig), these three planes are vertical mutually to form joining (being following location benchmark zero point), thereby forms six point locations.Certainly, the form of transition baseline is varied, is not limited to the above-mentioned concrete form that exemplifies of the present invention.
The second, in the first step S101 of above-mentioned basic embodiment, relate to some technological concepts, for example transition baseline zero point, main location benchmark zero point etc., this is known at the numerical control machine manufacture field, now gives schematic illustration in order to help to understand.
In numerically controlled processing equipment, numerically controlled processing equipment has the lathe coordinate system of self, corresponding numerically controlled processing equipment has lathe coordinate system MZP at zero point, the position of this lathe coordinate system MZP at zero point is fixed, it constitutes numerically controlled processing equipment and carries out mach basic point, the location recognition of numerically controlled processing equipment is based on all that this lathe coordinate system MZP at zero point carries out, and numerically controlled processing equipment needs to carry out rezero operation (general cutter moves to the lathe reference point with respect to lathe coordinate system MZP at zero point fixed-site) before carrying out workpiece processing be exactly this reason.
In addition, the location benchmark that has self on the workpiece, the location benchmark comprises corresponding location basal plane, according to six point location principles, three orthogonal location basal planes are intersected in a bit, and this point is location benchmark zero point, that is to say, location benchmark zero point might not be in esse point, and can be virtual location point or the locus point with definite position.The location benchmark generally constitutes the zero point of machining programming zero point, and the authorized personnel of procedure works out the size of each operation program needs processing zero point according to the location benchmark.For example, in the present invention, although there is main location benchmark, owing in the processing of engine cylinder-body, do not position with main location benchmark, but position by transition baseline, therefore with transition baseline zero point as programming zero point.When engine cylinder-body 1 when the transition baseline positioning and clamping is to the numerically controlled processing equipment, the setting element of jig contacts with the location basal plane of transition baseline, transition baseline overlaps with anchor clamps zero point zero point at this moment.
The transition baseline position of zero point in lathe coordinate system namely generally determined by tool setting technology with respect to the position of lathe coordinate system MZP at zero point, has various ways in the relevant tool setting technology prior art, do not repeat them here.In conventional machining process mentioned above, the following process of engine cylinder-body is directly described transition baseline zero point to carry out following process zero point as workpiece coordinate system.Machine tool all calculated processing dimension to workpiece zero point with respect to this workpiece coordinate system when so-called workpiece coordinate system zero point namely processed workpiece on numerically controlled processing equipment.But, as mentioned above, the processing of engine cylinder-body should be processed with main location benchmark as far as possible, although transition baseline WZP1 at zero point with respect to main location benchmark WZP2 at zero point in the lathe coordinate system of described numerically controlled processing equipment along X-axis, the theoretical distance value of Y-axis and Z-direction is respectively Δ X, Δ Y and Δ Z, but this theoretical distance value only is the ideal value that draws according to design drawing, it is transition baseline WZP1 at zero point has design in the lathe coordinate system of described numerically controlled processing equipment with respect to main location benchmark WZP2 at zero point distance value, but because mismachining tolerance and the positioning and clamping errors of engine cylinder-body on numerically controlled processing equipment of transition baseline itself, therefore transition baseline WZP1 at zero point with respect to main location benchmark WZP2 at zero point in the lathe coordinate system of described numerically controlled processing equipment along X-axis, the measured distance value of Y-axis and Z-direction inevitably with theoretical distance value Δ X, there are deviation in Δ Y and Δ Z, this deviation that is caused by the benchmark disunity can have influence on dimensional accuracy and the positional precision of the dependency structure of following process, thereby makes the processing inaccuracy.
The 3rd, in the second step S201 of above-mentioned basic embodiment, processing method of the present invention is under the state of described cylinder body 1 positioning and clamping, detect transition baseline WZP1 at zero point with respect to main location benchmark WZP2 at zero point measured distance value δ X, δ Y and δ Z along X-axis, Y-axis and Z-direction in lathe coordinate system, and calculate difference between each measured distance value and the corresponding theoretical distance value, i.e. difference φ Z between difference φ Y between difference φ X between δ X and the Δ X, δ Y and the Δ Y and δ Z and the Δ Z respectively.
The relevant detection method that adopts can have multiple, can measure by the mode of direct measurement the most simply, for example measures the numerical control unit that the measured distance value is input to numerically controlled processing equipment by photoelectric measurement method.Certainly, in the numerical control machine manufacture field, can measure by gauge head, for example can adopt contact measuring head in the processing method of the present invention, the parameter signal that is used for acquisition measured distance value that this contact measuring head will detect is transferred to the numerical control unit of numerically controlled processing equipment, thereby handles acquisition measured distance value and relatively each measured distance value and the difference between the theoretical distance value accordingly by numerical control unit.Described contact measuring head can be the contact measuring head that the parameter signal that detects can be wirelessly transmitted to the numerical control unit of numerically controlled processing equipment, for example the contact measuring head of Renishaw company of Britain's gauge head manufacturer production can be transferred to the numerical control of machine tools unit with the measurement parameter signal wireless in this gauge head measuring process in real time.Apparently, in order to finish above-mentioned testing, be used for realizing that the system of processing of processing method of the present invention should comprise corresponding checkout gear, be under the situation of horizontal Machining centers at numerically controlled processing equipment, owing to be built-in with the process of measurement (namely can handle the dependency structure parameter of contact measuring head transmission and the process of measurement of location parameter signal) of standard in the numerical control unit of horizontal Machining centers, therefore described checkout gear can be for realizing the contact measuring head of wireless transmission, the spindle nose that contact measuring head is installed to horizontal Machining centers when detecting is measured and is got final product, certainly since need to measure be transition baseline WZP1 at zero point with respect to main location benchmark WZP2 at zero point in lathe coordinate system along X-axis, the measured distance value of Y-axis and Z-direction, therefore generally need to set up to measure coordinate system, this measurement coordinate system can be determined the transition baseline position at zero point by tool setting technology with respect to lathe coordinate system zero point, and then be zero point that initial point is set up and measured coordinate system with transition baseline, this is apparently for those skilled in the art, embody in the procedure that exemplifies hereinafter, do not repeat them here.For example, in processing method of the present invention, contact measuring head is mainly used in measuring main location benchmark zero point with respect to the transition baseline position at zero point, setting up under the situation of measuring coordinate system zero point with transition baseline, detect structural parameters and the location parameter of the location structure of main location benchmark by contact measuring head 3, for example described master locatees two dowel holes that benchmark is generally the bottom surface of engine cylinder-body and is formed on this bottom surface, structural parameters signal by measuring two dowel holes in measuring coordinate system and the coordinate figure location parameter of four points on the engine cylinder-body bottom surface are also got its mean value, and then by measurement data signals is handled calculating, and according to described contact measuring head 3 when detecting with respect to the relative position at transition baseline zero point obtain transition baseline WZP1 at zero point with respect to main location benchmark WZP2 at zero point along X-axis, the measured distance value of Y-axis and Z-direction is respectively δ X, δ Y and δ Z.In addition; as a kind of simple variant form; if the numerically controlled processing equipment that adopts does not comprise under the situation of relevant canonical measure program; system of processing of the present invention can comprise independently checkout gear fully; this checkout gear can comprise the processing unit of contact measuring head and built-in process of measurement; the data that contact measuring head is measured can be through being transferred to the numerical control unit of numerically controlled processing equipment again after the processing unit processes, this simple variant form belongs to protection scope of the present invention equally.

By above-mentioned processing method of the present invention, although the present invention has adopted the location benchmark of transition baseline as engine cylinder-body, but since in process ingenious transition baseline and the main actual deviation of locating between the benchmark of having compensated, therefore can there be deviation in the dependency structure of the engine cylinder-body by processing method processing of the present invention substantially with respect to main location benchmark, that is to say, although processing method of the present invention has adopted transition baseline as the location benchmark, but can not produce the error that benchmark does not overlap because of the benchmark disunity, thereby improve the crudy of engine.
On the basis of the above-mentioned basic embodiment of processing method of the present invention, as mentioned above, usually, described main location benchmark is two dowel holes on the bottom surface (being the oil sump installed surface) of described engine cylinder-body 1 and the bottom surface that is formed on this engine; Described transition baseline is the false boss face that is formed on described engine cylinder-body 1 exhaust side, and each false boss face forms the location basal plane for the described engine cylinder-body 1 in location.More specifically, the structure of required processing can be the atomizer installing hole on the bottom surface of described engine cylinder-body 1 and/or oilhole etc. on the described engine cylinder-body.
Preferably, be formed with gauge orifice on the described jig, above-mentioned first step can also comprise the coordinate figure of the described gauge orifice of detection in the lathe coordinate system of described numerically controlled processing equipment, and the standard coordinate value of the coordinate figure that will detect and predefined this gauge orifice relatively, difference between the two is no more than the target offset value, to guarantee that the probe measurement precision meets technological requirement, for example when processing engine cylinder-body with process of the present invention, the target offset value is decided to be 0.03mm, as long as be no more than 0.03mm, illustrate that the certainty of measurement of probe meets technological requirement.Be to detect the accuracy that gauge head is measured in the set up standard main purpose in hole of jig, generally each order of classes or grades at school is with gauge orifice of probe measurement.Generally speaking, the position of the relative lathe of gauge orifice on jig MZP at zero point is fixed, if the standard coordinate value deviation of the actual coordinate value of probe measurement gauge orifice and setting illustrates then that greater than the target offset value probe measurement error is excessive, need to adjust or change.
Further, above-mentioned numerically controlled processing equipment can be horizontal Machining centers, generally can adopt the stronger four-axle linked formula horizontal Machining centers of versatility, there are general definition standard in the X-axis of the lathe coordinate system of machining center, Y-axis, Z axle, and what generally be parallel to the machining center main shaft is the Z axle, short transverse be Y-axis, another reference axis is X-axis, and in addition, the rotation of rotation platform 2 constitutes the B axle, this is known for those skilled in the art, repeats no more.Under numerically controlled processing equipment can the situation for horizontal Machining centers, preferably, can carry out the testing of each described measured distance value δ X, δ Y and δ Z by contact measuring head, and the data-signal that detects is transferred to the numerical control unit of described numerically controlled processing equipment, more preferably, described contact measuring head is wirelessly transmitted to the data-signal that detects the numerical control unit of described numerically controlled processing equipment.
