Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the spy enumerates following example and is described in detail as follows:
Embodiment 1
With reference to accompanying drawing 1 and Fig. 2.
Control method for curved-tooth angle gear chamfering, control three-shaft linkage lathe.Spiral bevel gear processing is according to the layout of chamfered edge lathe, the coordinate of motion, circular cone aligned cutting tool and the concavo-convex both sides of teeth groove tooth top crest line are carried out calculation control, determine the position relation between the work spindle of the workpiece teeth groove of chamfered edge and lathe, the concavo-convex both sides of cutter and teeth groove tooth top crest line pair is touched; Realize that control three-shaft linkage lathe carries out the processing of gear chamfered edge.
Calculation control comprises the automatic analysis phase, carries out the segmentation calculation stages according to the parameter of input, in the numerical value feedback prompting stage, removes the historical record stage.Carry out the feature of segmentation calculation stages according to input parameter, comprise that checking calculates; Error ratio is calculated; Calculate numerical value and feedback user; Can change parameter voluntarily; Calculate automatic calculating, checking and the feedback numerical value of each functions such as inner sin, cos, tan.Simple computation and Error Calculation stage comprise user's input parameter stage voluntarily, and the automatic calculating of function, checking be the feedback numerical value stage also.The feature of removing the historical record stage comprises, removes whole zero clearing stages of write parameters; Re-enter, calculation stages.
The calculation control chamfered edge forms face cone cutter tooth center line central angle and calculates when comprising the system tooth, form protruding, concave surface profile angle calculating during the system tooth; Teeth groove location Calculation before the chamfered edge.
The calculation control chamfered edge comprises that single, double curved surface chamfered edge calculates.
The control method for curved-tooth angle gear chamfering software workflow is as shown in Figure 1:
Program begins:
Windows begins retrieve data, and the open incident begins to carry out, and opens respective window, and the pending data input finishes, and the net incident is hit messagebox function alive.Enter program circuit.
Check the back and calculate, utilize the mid function to determine desired precision according to formula.After result of calculation was come out, the numerical value that goes beyond the scope occurred, and miscue will occur, requires the user to check again, to avoid wrong appearance once more.
There is a large amount of assignment type problems in program when calculating, and " type () " will force conversion, differentiates automatically.Requirement to angle also is quite responsive, cos, and sin, asin, acos, abs etc. are a large amount of to be calculated and self-defined computing formula.Tangible information is arranged on the user feedback interface, tell the user just belonging to the calculating content of any part in result calculated
In Error Calculation, requirement calculates the whole piece curve according to the starting point and the terminal point of user's input according to error, the hop count that curve is divided shows with counting, 2 is one section, when if the error of this section is greater than or less than the error of operator's requirement, computing machine will add or deduct 1S automatically, cause to accomplish the error minimum value of approaching most, make that the workpiece that processes is the most perfect, the most reliable.And then be the value that basic calculation goes out each point that this curve divides with the mathematical model.
For example: if tell at 20 and just have X, the Y of 20 points, the value of Φ, the value of this moment has nothing to do with the value of X, the Y of aforementioned authentication, Φ, and lathe needed be these 20.
Calculating recited above comprises simple computation and Error Calculation, is by user's input parameter voluntarily, and the automatic calculating of each functions such as inner sin, cos, tan, checking be feedback numerical value also, and all can use on polytype chamfered edge.
The system module flow process of control method for curved-tooth angle gear chamfering is as shown in Figure 2:
System module begins:
After result's calculating finishes, system rests on software under the current state, precision of calculation results will can not lost, if result calculated has problem, the user can single removing or the existing parameter of full scale clearance, the program of arranging software again will be put and section is reselected, through feedback result once more after calculating.
Meanwhile, desired precision problem is not if there is difference, and system will come out all numerical evaluation within the 2S clock.If not re-using computing function can return main interface or quit a program that to wait this type of little function be all attainable.
The present invention has adopted the man-machine dialog interface function, comes the needed information of feedback user with effect of visualization.And be a non-localized processing software for calculation, can calculate a plurality of useful datas, taken leave of single main processing numerical value, can calculate up to a hundred curved tooth processing numerical value and rotation numerical according to user's requirement according to the modulus of different sizes.In calculation process, spiral bevel gear is divided into single, double two kinds of chamfered edges calculates, be divided into top rib, central angle, chamfered edge.Comprise the automatic analysis of system, carry out segmentation according to the parameter of input and calculate simple computation etc., can keep current state after the prompting of numerical value feedback and also can remove historical record.
