The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Fig. 1 to 5 show a method for synchronously calibrating a Y-position and four-axis rotation angles according to an embodiment of the present invention.
The synchronous correction method of the Y-direction position degree and the four-axis rotation angle comprises the following steps:
s100: adjusting the posture of the clamp 10: the Y-direction of the jig 10 is adjusted to a horizontal state to match the machining coordinate system of the milling cutter work, and the rotation axes of the four-axis drivers are arranged in the X-direction of the machining coordinate system of the milling cutter work.
For convenience of operation and calculation, in the present embodiment, as shown in fig. 1 and 2, the rotation center points of the four-axis driver, the jig 10, and the product 20 are set to coincide with each other during the erection.
S200: detection of key slot 21 probe: detecting a first probe point and a second probe point on a side of the product 20 by a probe, wherein the first probe point is located at one end of the key groove 21; the second probe point is located at the other end of the key way 21.
As shown in fig. 2 and fig. 3, the first probe point is marked as N, and the second probe point is marked as M, in the example of the present embodiment, the first probe point N is lower than the preset Y-direction horizontal position, and the second probe point M is higher than the preset Y-direction horizontal position.
And S300, calculating a probe point difference value, namely obtaining the difference value △ hz of the side edge of the product 20 in the Z direction and the difference value △ Ly of the side edge of the product 20 in the Y direction according to the first probe point and the second probe point.
Since the coordinate value of each probe point includes the values of XYZ in three dimensions, in the present embodiment, since the rotary jig 10 does not generate a deviation to the X direction of the product 20, the variable in the X direction is 0, therefore, in this embodiment, when the probe detects the first probe point N and the second probe point M, the three-dimensional coordinates of the first probe point N and the second probe point M are obtained, and the absolute values are obtained by performing a difference in the corresponding dimensions, so that △ hz and △ Ly are obtained, respectively.
And S400, calculating a Y-direction offset value Dy of the initial coordinate value of the milling operation caused by the rotation of the clamp 10 through a trigonometric function according to the size α of the deflection angle of the side edge of the product 20 relative to the Y direction of the clamp 10 and the same deflection angle β required for rotating the clamp 10 to adjust the side edge of the product 20 to be in a horizontal state.
The step S400 may include the steps of:
and S410, determining a trigonometric function tan α - △ hz/△ Ly according to the geometric relationship between the first probe point and the second probe point, wherein α is the size of the deflection angle of the side edge of the product 20 relative to the Y direction of the clamp 10, and α -arctan (△ hz/△ Ly) is obtained, as shown in FIG. 4, constructing a right triangle at the first probe point N and the second probe point M, and determining a trigonometric function tan α - △ hz/△ Ly.
And S420, establishing a trigonometric function of the rotation center point and the Y-direction offset, namely determining the trigonometric function sin β which is Dy/R according to the geometric relationship between the side edge of the product 20 and the rotation center point, wherein β is the size of a deflection angle required by the rotary fixture 10 to adjust the side edge of the product 20 to be in a horizontal state, Dy is the size of Y-direction position offset of initial coordinate values of milling cutter operation caused by rotation, R is the size of distance between the side edge of the product 20 and the rotation center point in the Z direction after being adjusted to be in the horizontal state, Dy is sin β R, as shown in FIG. 5, constructing a right triangle between the side edge of the product 20 and the rotation center point, and determining the trigonometric function tan α △ hz/△ Ly., wherein a solid line box represents the product 20 after being rotated to be in the horizontal state, and a dotted box represents the product 20 before being rotated.
Since the center of the rotating shaft of the four-axis driver, the center of the fixture 10, and the center of the product 20 are overlapped in this embodiment, R is half of the distance between the side where the key slot 21 of the product 20 is located and the opposite side.
Further, the manner of obtaining R may be various.
For example, R is calculated from parameters provided in the specification of the product 20.
As another example, by a dimensional measurement calculation of the product 20.
As another example, it is obtained by probe inspection after the product 20 is rotated to a horizontal state.
And S430, obtaining β (α) according to the purpose of adjusting the side edge of the product 20 to be horizontal by rotating the clamp 10, obtaining a correction angle required by four-axis rotation, and further obtaining Dy (sin [ arctan (△ hz/△ Ly) ]. R).
S500: correcting the machining coordinate of the milling cutter operation: and Dy is substituted into a machining coordinate system of milling cutter operation to correct the machining coordinate of the milling cutter operation, the offset of the Y-direction position degree generated by the rotary fixture 10 is compensated, and the synchronous correction of the Y-direction position degree and the four-axis rotation angle of the key groove 21 is completed. And simultaneously, the four-axis driver drives the clamp 10 to rotate so as to correct the posture of the product 20, and synchronously corrects the Y-direction numerical value of the machining coordinate of the milling cutter operation according to the Y-direction position degree offset of the rotated product 20.
In addition, in the present embodiment, the α and β are only used to indicate the size of the angle, and in the actual operation, it is also necessary to determine the direction of the angle that the jig 10 needs to rotate when the side of the product 20 is adjusted to be horizontal, for example, clockwise or counterclockwise, for example, as shown in fig. 4 and 5, in the illustrated example of the present embodiment, the first probe point N is lower than the second probe point M in the Z direction, and therefore, the jig 10 needs to rotate β counterclockwise to adjust the posture of the side of the product 20, and then, the positive or negative value of Dy substituted into the machining coordinate system of the milling cutter operation can be determined according to the deflection direction of β.
For example, in the present embodiment, if the coordinate value of the first probe point N in the Z direction is larger than the coordinate value of the second probe point M in the Z direction, the first probe point N is deflected downward in the Z direction to be β, which corresponds to the clockwise direction in the present embodiment, whereas, the first probe point N is deflected upward in the Z direction to be β, which corresponds to the counterclockwise direction in the present embodiment.
In addition, the device can be improved in terms of convenience and stability of clamping the product 20, convenience of assembling the device, and the like.
For example, the carrying surface of the fixture 10 is provided with a vacuum chuck for adsorbing the product 20. The vacuum chuck is used for generating a suction force in the X direction. When the product 20 is clamped to the clamp 10, the stability is enhanced by vacuum suction through the vacuum chuck.
For another example, as shown in fig. 2, in the present embodiment, the fixture 10 is provided with a positioning post 11 penetrating through the product 2020, and the positioning post 11 is disposed perpendicular to the bearing surface of the fixture 10.
For another example, the jig 10 is provided with a clearance hole through which the rotating shaft of the four-shaft driver is inserted.
According to the synchronous correction method for the Y-direction position and the four-axis rotation angle, under the condition that the clamp 10 is in a horizontal state, the coordinate values of the detection points at the two ends of the key slot 21 on the side edge of the product 20 are respectively detected, and the rotation angle required by adjusting the product 20 to be in the horizontal state is converted by utilizing the geometric relationship between the two detection points and combining the trigonometric function relationship. And according to the geometric relationship between the side edge of the product 20 and the rotation central point, in combination with the trigonometric function relationship, the magnitude of the Y-direction position degree offset of the initial coordinate value of the milling cutter operation caused by rotation is converted, and the magnitude of the Y-direction position degree offset is substituted into the processing coordinate system of the milling cutter operation to correct the processing coordinate of the milling cutter operation, compensate the Y-direction position degree offset generated by the rotary clamp 10, and complete the synchronous correction of the Y-direction position degree and the four-axis rotation angle of the keyway 21 processing, thereby solving the Y-direction deviation problem caused by the rotary clamp 10 and improving the processing precision of the milling cutter operation.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above examples only express preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
