Abstract

A high precision rotation revolving thermal deformation measurement system is used for measuring displacement error and angle shift generated from temperature increase on a revolving spindle, which is characterized in comprising an optical read/write head having a light source and a light path, a reflection mirror connected with the revolving spindle, a spectroscope, a biconvex lens and two optical sensors. The design utilizes a light reflection theory. A reflection light coming from the light source and passing through the spectroscope is split to irradiate one of the optical sensors after passing through the biconvex lens and another optical sensor is irradiated with the reflection light directly. The error in the degree of freedom of the revolving spindle is obtained from the two optical sensors respectively. Therefore, the effectiveness of reduced measurement equipment cost and improved measurement precision technique is achieved.

[Prior Art] Press, the rotary axis A of the general machine tool has multiple degrees of freedom error. In actual motion, six degrees of freedom errors in the X, Y, and Z directions are generated on the reference axis due to temperature effects; As shown, with respect to the six-degree-of-freedom error, it includes three line errors, namely εχ(θ), ε/θ), εζ(θ), and three angular errors, ie, pitch error δχ(θ). , Yaw degree error δ γ (θ) and rolling (Roll) degree error δ ζ (θ). Since the rotating shaft 组装 is assembled by components such as a spindle 轴承, a bearing, a driver, and the like, an error having a plurality of degrees of freedom is generated due to an error in the size of the component, a degree of fit between the components, and the like, and the characteristics of the rotating shaft A in the machine will be Affects the accuracy of the entire machine and the quality of the processed product. Therefore, the machining dimensions of the precision workpiece to be machined need to consider the error of six degrees of freedom. With the development of the rotating axis A measuring technology, the rotating axis A measuring technology currently used has the following classifications, as follows: 1. Direct use of the standard ball (axis) / axis (axis) / rod (cylinder), but does not compensate for the error of the rotation axis A: 5 1285254 month μ μ: (2) positive replacement page This method is the earliest rotation axis measurement technology, because this technology will be limited by the standard rod / ball processing accuracy Therefore, it is not suitable for high-precision measurement, because in the paper of Eric in December of the next year, the technology provided can measure 1 μm resolution. However, in the article of Robert E. Gleason, he proposed the current processing technology. The limit, the standard sphericity of the ball (out 〇f roundness) is 75 (10), and the ultimate accuracy of the Air Spindle can reach 50 nm, so the first type of method is still impossible to achieve with the current technology.

直接使用標準球(master ball)/ 轴(axis)/ 棒 (cylinder),但補償旋轉轴a之誤差,補償方式為單探 定(multi-steps):Use the master ball/axis/cylinder directly, but compensate for the error of the rotary axis a. The compensation method is multi-steps:

The laser diode is irradiated to the mirror mounted on the rotating shaft through a beam splitter to measure the error of the rotating shaft. At this time, the reflected light is generated by the mirror, and the _beam splitter generates the transmitted light and the opposite material respectively. On the two light sensors, the change of #点1285254 丫¢) the year and month [compulsory repair, 疋 replacement page to measure the degree of freedom error; according to this, when there is an error in the rotation axis, it will cause reflected light The change, in turn, affects the position where the reflected light hits the photosensor, and then obtains the translation and angle error values through mathematical operations. [Embodiment] In order to further understand the present invention, the present invention aims at the foregoing invention and The features and the detailed description of the preferred embodiment and the drawings are as follows: The technical means and the efficiency of the high-precision rotating shaft thermal deformation measuring system designed according to the present invention are described in detail with the best embodiment and the cooperation diagram. Bottom: As shown in FIG. 5, the present invention provides a high-precision rotating shaft thermal deformation measuring system, and the structure thereof comprises: a mirror 1 having a size of about 1 mm X 1 mm, which is a turning point of 180 degrees for light. to A device (such as a micro-milling machine, a micro-drilling machine, a micro-engraving machine, etc.) is mounted on the rotating shaft 10 to generate reflected light for the illumination of the optical pickup head 2; The head 2 is a head of a digital CD player DVD, which is set at the side of the near-rotation axis 10, and has a built-in laser light source and an optical path that can turn the light into a 90-degree turn (not shown). For emitting laser light to the mirror 1 connected to the rotating shaft 10. The beam splitter 3 is set up in the vicinity of the adjacent optical pickup 2, and the square beam splitter is optimally used, and the circular plate type beam splitter can also be used, and the square beam splitter is characterized by a mirror type spectroscope. With a large penetration and reflection contact area, the beam splitter 3 causes 8 to replace the 3 1285254 laser light for a 90 degree turn, and allows the reflected light of the mirror 1 to pass through, thereby generating a splitting light, that is, splitting two lights (vertical And a horizontal direction); a light is transmitted light for passing through the lenticular lens 4 into the first photo sensor 5 to measure the pitch error δ χ (θ) of the rotating axis, and the skewness error δ γ (θ) The other angle is the reflected light. The other light is the reflected light. After returning to the optical head 2 and turning the light through the internal optical path for 90 degrees, it is directly driven into the second photo sensor 6 to measure the displacement error signal of the rotating shaft. (Line error ε χ (θ), ε / θ)) and angle error signal (angular error δ χ (8), δ γ (0)). The lenticular lens 4 is disposed at another corresponding position adjacent to the optical pickup 2 for penetrating the transmitted light of the spectroscope 3 for filtering the displacement signal of the transmitted light to make the first light sensation The detector 5 can obtain an angular offset signal of the rotating shaft 1 ;; the first photo sensor 5 is a four-line optical sensor disposed at a corresponding position of the adjacent lenticular lens 32, which is based on the light spot. The change is measured, and then the degree of freedom error of the angular offset value such as the pitch error δχ(0) and the skewness error δγ(θ) is obtained through the analog/digital conversion card (A/D card) conversion. The second photo sensor 6' is a four-line optical sensor disposed adjacent to the side of the optical pickup 2, and is also measured according to the change of the spot, and then converted by an analog/digital conversion card. The degree of freedom error of the displacement and angle error signals is obtained. As shown in FIG. 6 and FIG. 7 , the high-precision rotating shaft thermal deformation measuring system of the present invention does not count, and the laser beam of the optical pickup 2 is used to generate a laser beam in a γ direction during the continuous measurement. After the emission, it is first reflected by a beam splitter 3 to a lmmxlmm mirror (丨) on the rotating shaft 1〇, so that the laser beam irradiated on the mirror 1 produces an inverse 9 and replaces the page; 1285254 emits light. The beam splitter 3' is divided into a transmitted light and a reflected light. After passing through the lenticular lens 4, the transmitted light enters the first photo sensor 5, so that the first photo sensor 5 can be obtained by the first photo sensor 5. Measuring the angular offset value of the tilting error δχ and the skewness error δγ of the rotating shaft 1;; the reflected light is returned to the optical pickup 2 and the light is turned 90 degrees through the internal optical path, and then directly enters the first The second light sensor 6 can be used to measure the displacement and angular error signals of the rotating shaft by the second light sensor 6. In addition, the first and second photo sensors 4, 5 can be accurately determined by the analog/digital conversion card conversion and data operation. That is, when the rotation axis 10 generates a translation error (line error ε χ (θ), sy (0)), angular deviation (angular error center (0), ^ 0) due to temperature rise, the rotation axis is caused by the rotation axis The 10 connecting mirror 1 generates a change of the reflected light, thereby affecting the position where the reflected light hits the first photo sensor 5 and the second photo sensor 6, and then measures according to the change of the spot, and then passes through After the mathematical operation, the translation and angle error values are obtained. Therefore, the high-precision rotating shaft thermal deformation measuring system of the present invention uses the mirror 1, the optical reading head 2 with the laser light source and the optical path, the beam splitter 3, the lenticular lens 4, and the first quadrant photo sensor. 5 and the second light sensor 6, has the following characteristics: 1. Mirror 1: can make the light turn 180 degrees, and reduce the measurement structure. 2, optical 5 buy write head 2 · easy to obtain, low cost, and optical read / write head 2 built-in laser light source and light path can be turned 90 degrees, without the use of expensive laser diode and Can be used with another spectroscope. 1285254 i : .. . . , , and .-, one···"·v -- · **ynd^vmr -ϊγΤλΛ 3, Beamsplitter 3: The reflected light source can be split after passing through the beam splitter 3 ( Vertical and horizontal directions). 4.

The first photo sensor 5 and the second photo sensor 6 are both measured according to the change of the received light spot, and then converted by the analog/digital conversion card to obtain the rotation axis when the temperature rises. Other degrees of freedom error are generated; however, the first photosensor 5 must first filter the displacement signal of the transmitted light source through the lenticular lens 4, thereby obtaining an angular offset value such as the pitch and the skewness of the rotating shaft; The two-photo sensor 6 can measure the displacement and angle error signals of the rotating shaft, and finally the analog-degree/digital conversion card conversion and data operation can accurately determine the degree of freedom error.
