Abstract
Description
Technical Field
[0001] The present invention belongs to the field of machine tool processing, and particularly relates to a measuring device for dynamically optimizing motion variables of a machine tool. Background Art
[0002] A machine tool is a machine specifically used for processing metals or other materials, aiming to endow workpieces with the required geometric shapes, dimensional accuracies, and surface qualities.
[0003] A lathe is a machine tool mainly used for turning a rotating workpiece with a turning tool. Drills, reamers, taps, dies, knurling tools, etc. can also be used for corresponding processing on a lathe. Lathes are mainly used for processing shafts, discs, sleeves, and other workpieces with rotating surfaces, and are the most widely used type of machine tool in machinery manufacturing and repair factories.
[0004] In order to maintain the machining accuracy of a machine tool, it is necessary to frequently measure machining errors and adjust and maintain the machine tool according to the machining errors.
[0005] For example, a method for tracing the dynamic error of a numerically controlled machine tool based on the machining error of an S-shaped specimen disclosed in a Chinese patent with the publication number CN111813044A. First, measure the S-shaped specimen to determine the position of the error patterns of the S-shaped flange contour error, thickness error, indentations, ridges, and vibration marks; second, analyze the interpolation instructions of the numerical control system for machining the S-shaped flange, and establish a curve of the command bandwidth varying with the flange position and a distribution map of the potential excitation frequency on the flange; third, identify the servo bandwidth and mechanical natural frequency of each axis servo feed system of the numerically controlled machine tool; finally, analyze the relationship between the command at the error position and the servo bandwidth and mechanical natural frequency to achieve the tracing of the dynamic error of the machine tool.
[0006] However, the currently commonly used measurement method is to measure various machining parameters after machining is completed. In addition, it has the following disadvantages:
[0007] 1) In the traditional dynamic processing state of a machine tool, the degree of mechanization and automation is low, and it is impossible to dynamically implement dynamic optimization step by step during the cutting process of the machine tool operation, that is, for conventional motion variables, such as vibration, temperature, and various technical characteristics of the dynamic characteristics, natural frequency, and vibration mode of the surface of cutting and drilling parts, the corresponding motion changes are generally uncontrollable, and in terms of the corresponding intelligent production, it is not convenient enough to solve the problem of too low measurement accuracy existing in the prior art.
[0008] 2) In general, the traditional dynamic state of machine tools is likely to result in inaccurate mapping of the dynamic movement path of machine tools, leading to inaccurate judgment of the efficiency in the later operation and maintenance of machine tools. The data obtained usually cannot achieve dynamic variable mapping and cannot make better contributions to on-site production and calibration. In terms of some machine tool dynamic measurements, there are generally problems such as low measurement accuracy, the inability of the produced lathe devices to fit well with the software, the lack of the function of making actual corrections during production, a relatively single automated correction scheme, and the inability to provide better feedback for automated programmed corrections.

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention and do not impose any limitations on it.
[0046] As Figures 1 to 3 shown, a machine tool dynamic optimization motion variable measuring device includes an outer protection mechanism 1, a variable measuring mechanism 2, a machine tool processing mechanism 3, and a turning mechanism 6.
[0047] The outer protection mechanism 1 includes an outer protection box 11, a connection and assembly seat 12, and an outer frame cover 13.
[0048] At the four corners of the bottom of the outer protection box 11, there are connecting struts 14. At the bottom of the connecting struts 14, there are connection pads 15. On the top of the connection and assembly seat 12, an outer frame cover 13 is installed. Inside the side wall of the outer frame cover 13, there is a processing cavity 16.
[0049] The front surface of the outer frame cover 13 is an articulated arc-shaped connection cover 17. On the surface of the arc-shaped connection cover 17, there are arc-shaped connection strips 18. On the surface of the arc-shaped connection cover 17 (i.e., one surface of the outer frame cover 13), there is a workpiece placement cover 19. On the surface of the workpiece placement cover 19, there is an access door 191 for sealing.
[0050] At the top of the outer frame cover 13, there is an upper protection top cover 192. In the middle of the top of the upper protection top cover 192, there is a sensing mechanism 4.
[0051] The sensing mechanism 4 includes an ultrasonic scanning seat 41 established on the top surface of the upper protection top cover 192. On both sides of the ultrasonic scanning seat 41, there are induction strips 42 for sensing in sequence. The ultrasonic receiving end at the bottom of the ultrasonic scanning seat 41 is inductively set with the bottom surface of the upper protection top cover 192.
[0052] In this embodiment: on the side wall of the upper protection top cover 192, there is a display screen 43, and a workpiece vibration mode image is displayed on the surface of the display screen 43.
[0053] At one corner of the top of the upper protection top cover 192, a connection base 44 is vertically installed. In the middle of the top of the connection base 44, an alarm indicator tube 45 is vertically installed. At the bottom of the alarm indicator tube 45, there is a lathe vibration detection probe used to detect the position of the cutting tool head during machining and turning.
[0054] The information detected by the ultrasonic scanning seat 41 sensed by ultrasonic waves is adopted by the display screen 43.
[0055] As Figure 4 shown, in this embodiment: the variable measuring mechanism 2 is composed of an arc-shaped guide rail 21, a linear moving motor 22, a self-folding bracket 23, and a sliding seat 24.
[0056] The arc guide rail 21 is successively connected to the bottom side of the upper protective top cover 192. The linear movement motor 22 is successively arranged on the bottom surface of the arc guide rail 21. There are two self-folding brackets 23, which are respectively installed on the bottom surface of the arc guide rail 21. A three-dimensional dynamic scanner 231 for dynamic detection is provided at the end of one of the self-folding brackets 23, and a dynamic detection image recognition lens 232 is built into the three-dimensional dynamic scanner 231.
[0057] Both of the two self-folding brackets 23 linearly move along the arc guide rail 21 through the linear movement motor 22.
[0058] A dynamic vision sensing mechanism 5 for dynamic vision capture is also installed at the end of the other self-folding bracket 23.
[0059] The information in the operation stage is scanned by the adopted self-folding bracket 23 and the three-dimensional dynamic scanner 231. In addition, in order to change the path orientation position of the scan, it moves automatically on the surface of the arc guide rail 21.
[0060] In the lathe machining stage, for the monitoring of various parameters generated in turning, drilling or other machining aspects, it depends on the arc guide rail 21. As the connection movement of the self-folding bracket 23, through the energization of the linear movement motor 22 and the intelligent control of the PLC controller 111, the intelligent capture of information during the dynamic operation of the machine tool is carried out. Then, through the measurement of the captured motion variables, the mechanical equipment for the turning production of each numerical control lathe is inversely controlled to optimize the motion variables.
[0061] The workpiece itself in the production cutting stage is directly irradiated by the three-dimensional dynamic scanner 231. Through the dynamic detection image recognition lens 232, as the detection of the three-dimensional dynamic scanner 231, this detection can further achieve dynamic changes in the shape of the workpiece being machined (showing an image model with a gradual change of red, yellow and blue).
[0062] Such as Figure 4 and 5 As shown, the dynamic vision sensing mechanism 5 includes a dynamic vision sensor 51 installed on the side wall of the other self-folding bracket 23. A plurality of lens recognition brackets 52 are provided at the end of the dynamic vision sensor 51. A connection seat is provided on the surface of the lens recognition bracket 52. An arc bracket 53 for support is provided at the end of the connection seat. An adjustment bracket 54 for support is provided on the side wall of the arc bracket 53. A first sensing probe 55 for workpiece scanning detection is provided at the end of the adjustment bracket 54.
[0063] After the adopted arc bracket 53 is connected with the induction coil, the support of the adjustment bracket 54 is used to determine the processing recognition object according to the analysis lens 56.
[0064] In this embodiment: A number of analysis lenses 56 are sequentially arranged on the surface of the first sensing probe 55. A connecting base 57 for connection is cross - arranged between the number of analysis lenses 56. On the side wall surface of the arc - shaped bracket 53, two arc - shaped regulating frames 58 are sequentially installed. On both sides of the top of the two arc - shaped regulating frames 58, connecting vertical rods 59 for support are respectively provided. On the surface of the connecting vertical rod 59, a detection base 591 is fixedly installed. On the top surface of the detection base 591, a temperature detector 592 for identifying temperature is provided. On the end surface of the temperature detector 592, a second sensing probe 593 for adjustment is sequentially provided. The second sensing probe 593 is integrated with a vibration arc identifier 594, and the vibration arc identifier 594 is attached with a polarization identification chip 595.
[0065] The temperature detector 592 and the second sensing probe 593 used work together and coordinate to improve the analysis and identification of vibrations in the temperature detection state. The vibration arc identifier 594 accurately obtains vibration data, and the polarization identification chip 595 is used for the analysis of vibration information.
[0066] In this embodiment: In the middle of the bottom end of the sliding seat 24, a vibration detection plate 241 for vibration detection is provided. On the surface of the vibration detection plate 241, a number of vibration analyzers 242 for identification are cross - arranged. In the middle of the number of vibration analyzers 242, a baffle for separation is crossed. On the bottom surface of the arc - shaped guide rail 21, a thermal imager 243 for ambient temperature detection is also installed. At the bottom of the thermal imager 243, a thermal imaging base 244 is installed. The recording ends of the thermal imaging base 244, the second sensing probe 593, the vibration arc identifier 594, the dynamic vision sensor 51, the first sensing probe 55, the vibration detection probe, and the dynamic detection image recognition lens 232 are all opposite to the detection view positions of the machine tool processing mechanism 3.
[0067] The image recognition of the thermal imager 243 used, with the image input between the thermal imaging bases 244, promotes the acquisition and presentation of thermal information.
[0068] By combining the functions of the dynamic vision sensing mechanism 5, the external shape processing changes of the processed object are dynamically recognized and accurately controlled. The change process of the appearance cutting is maintained, and the consistency of the input of the real appearance is ensured. First, the workpiece is captured according to the dynamic vision sensor 51. The captured workpiece has a green frame and other red and blue recognition frames at different positions of the processed workpiece. The implementation principle of these frames is through the analysis lens 56 and the first sensing probe 55 for precise capture.
[0069] The green color is given to the detection of the analysis lens 56. When the workpiece approaches the recognition area, it is positioned by the analysis lens 56, and the presented range is box - selected and observed on the display through the green frame.
[0070] The blue color identifies the state information of the product's own vibration determined by the combination of the vibration arc identifier 594 and the polarization identification chip 595. It can show the more detailed vibration changes of the product during the processing stage, as well as the arc correction data information between the polarization of the machine itself (the vibration of the machine itself is obtained by using the ultrasonic scanning base 41 to scan downward as the detection and analysis to obtain the specific vibration data of the ultrasonic wave, so that the data matching degree of the two is constant, achieving the effect of polarization correction and data calibration).
[0071] The red color identifies the temperature information generated during the cutting of the tool when the tool head faces the workpiece. The way to obtain the information is: through the cooperation of the temperature detector 592 and the thermal imaging base 244 to achieve the cooling image of the imaging (it is a kind of video image in the form of a contour negative film from blue to orange to red). During production, workers can switch the images of each perspective at any time. This perspective image is automatically summarized by the PLC program and can be automatic or manual, assisting people to make accurate data references and improving the precision characteristics of production.
[0072] Moreover, the perspective is adjustable. The self-folding bracket 23 is used for the storage, folding, adjustment and induction of the probe during the detection stage.
[0073] After obtaining the above data, the machine can automatically make production judgments beyond ordinary people to assist workers in processing more accurate workpieces that are not affected by the environment, further improving the precision of the machine tool itself during processing.
[0074] Such as Figure 6 As shown, the machine tool processing mechanism 3 includes a five-axis turning seat 31 arranged on the side wall of the processing cavity 16. The middle part of the five-axis turning seat 31 is driven by a motor with a five-axis cutting clamping disk 32. Clamping fixtures 33 are arranged around the surface of the five-axis cutting clamping disk 32. Adjusting bases 34 for adjustment are installed at the four corner positions of the clamping fixtures 33. A clamping base 35 for adjustment is arranged in the middle of the adjusting base 34. A transverse cutting rod 36 is horizontally installed in the middle of the bottom end of the clamping base 35. The other end of the transverse cutting rod 36 is telescopically arranged with a pneumatic cylinder 37.
[0075] The adopted transverse cutting rod 36, under the control of the pneumatic cylinder 37, further promotes the stability of the machine tool processing and the more accurate cutting effect.
[0076] Such as Figure 7As shown in the figure, the turning mechanism 6 includes a linear pushing bracket 61 placed on the inner bottom surface of the outer frame cover 13. A pushing lead screw 62 is horizontally installed in the middle of the linear pushing bracket 61. Rubber buffer pads 63 are installed at the four corner positions of the bottom of the pushing lead screw 62. In the middle of the top of the linear pushing bracket 61, there is a square support plate 64. In the middle of the top of the square support plate 64, there is a linear sliding convex block 65. A first driving motor 66 is installed on the side wall of the linear sliding convex block 65. The output end of the first driving motor 66 is slidably arranged on the surfaces of two linear sliders 67. The first driving motor 66 adopted drives the positions of the two linear sliders 67 to change after the motor is powered on.

An angle clamping motor 69 is installed on the outside of one of the linear sliders 67. The output end of the angle clamping motor 69 is connected to the linear guide plate 692 through a clamping plate 691.
[0078] A trapezoidal mechanism 7 is installed on the back of the linear pushing bracket 61. The trapezoidal mechanism 7 includes an I-shaped bracket 71 installed on the back of the linear pushing bracket 61. A drilling bracket 72 is vertically installed in the middle of the top of the I-shaped bracket 71. A second driving motor 73 with its output end facing downwards is provided in the middle of the top of the drilling bracket 72.
[0079] The output end of the second driving motor 73 is connected to a driving lead screw 75 through a coupling 74. The driving lead screw 75 is in threaded cooperation with a fitting support plate 76. A drilling motor 77 is installed on the surface of the fitting support plate 76. The bottom rotating end of the drilling motor 77 corresponds to the surface position of the access base 693.
[0080] The coupling 74 and the drilling motor 77 adopted cooperate with each other to further process some structures that require drilling operations.
[0081] As Figure 8 and 9 shown, in this embodiment: An operation console 131 is installed on the side wall surface of the outer frame cover 13.

A PLC controller 111 is installed inside the outer protection box 11.
[0082] Through the mutual adaptation between the adjustment panel 134 and the operation console 131 adopted, the recognition of the corresponding computer is achieved.
[0083] The workpiece is placed on the surface of the access base 693. By the cyclic movement of the push screw rod 62, the position of the square support plate 64 is changed. When the drilling and cutting end performs cutting, the position of the cutting end is continuously changed. Through the access base 693, the positioning and cutting of the workpiece are carried out. In addition, for the auxiliary production in multiple axial directions, by controlling the numerical control machine tool, as the dynamic production of the corresponding machine tool, the disk surface positioning and matching of the five-axis turning seat 31 and the five-axis cutting chuck 32 are utilized. As the position change between the cutting tools that need to be cut, according to the mutual cooperation of the clamping fixture 33 and the clamping base 35, it is clamped while cutting, weakening the vibration arc of the equipment during the drilling and cutting of the cutting drill bit.
