Description

Technical Field

[0001] The invention belongs to the field of machine tool processing, and in particular relates to a machine tool dynamic optimization motion variable measuring device. Background Art

[0002] A machine tool is a machine specifically designed to process metal or other materials to give the workpiece the desired geometry, dimensional accuracy and surface quality.

[0003] Lathes are machine tools that mainly use turning tools to turn rotating workpieces. Drills, reamer, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tools in machinery manufacturing and repair factories.

[0004] In order to maintain the accuracy of machine tool processing, it is necessary to measure the processing error frequently and adjust and maintain the machine tool according to the processing error.

[0005] For example, a Chinese patent with publication number CN111813044A discloses a method for tracing the dynamic errors of CNC machine tools based on S-shaped specimen processing errors. First, the S-shaped specimen is measured to determine the position of the S-shaped edge strip where the error forms of contour error, thickness error, dents, ridges and vibration marks are located; secondly, the interpolation instructions of the CNC system for S-shaped edge strip processing are analyzed to establish a curve of the change of instruction bandwidth with the edge strip position and a distribution diagram of the potential excitation frequency on the edge strip; thirdly, the servo bandwidth and mechanical natural frequency of the servo feed system of each axis of the CNC machine tool are identified; finally, the relationship between the instructions at the error location and the servo bandwidth and mechanical natural frequency is analyzed to achieve the tracing of the dynamic errors of the machine tool.

[0006] However, the commonly used measurement method at present is to measure various processing parameters after the processing is completed. In addition, it also has the following disadvantages: 1) In the dynamic processing state of traditional machine tools, the degree of mechanization and automation is low, and it is impossible to implement dynamic optimization step by step during the operation and cutting process of the machine tool. That is, the conventional motion variables, such as vibration, temperature, dynamic characteristics of the surface of cutting and drilling parts, natural frequency, and various technical characteristics of vibration mode, generally have corresponding uncontrollable motion changes, and the corresponding smart production is not convenient enough, and it is impossible to solve the problem of low measurement accuracy existing in the existing technology.

[0007] 2) The dynamic state of traditional machine tools usually makes it easy for the dynamic motion path mapping of machine tools to be inaccurate, resulting in inaccurate judgment of the efficiency of the subsequent operation and maintenance of machine tools. The acquired data usually cannot achieve dynamic variable mapping and cannot make better contributions in production and calibration. For some machine tool dynamic measurements, there is generally low measurement accuracy, the lathe devices produced cannot fit the software, and do not have the function of actual correction during production. The automated correction solution is relatively simple and cannot provide better feedback for automated programmed correction.

[0008] Therefore, in order to realize the calibration of machine tools while producing, it is urgent to design a new machine tool dynamic optimization motion variable measurement device. Summary of the invention

[0036] like Figure 1~Figure 3 As shown, a machine tool dynamic optimization motion variable measurement device includes an external protection mechanism 1, a variable measurement mechanism 2, a machine tool processing mechanism 3 and a turning mechanism 6.

[0037] The outer protection mechanism 1 comprises an outer protection box 11 , a connection assembly seat 12 and an outer frame cover 13 .

[0038] Connecting struts 14 are provided at the four corners of the bottom of the outer protective box 11 , and connecting pads 15 are provided at the bottom of the connecting struts 14 . An outer frame cover 13 is installed on the top of the connecting assembly seat 12 , and a processing cavity 16 is opened inside the side wall of the outer frame cover 13 .

[0039] The front surface of the outer frame cover 13 is a hinged arc-shaped connecting cover 17, the surface of the arc-shaped connecting cover 17 is provided with an arc-shaped connecting strip 18, the surface of the arc-shaped connecting cover 17 (i.e. one of the surfaces of the outer frame cover 13) is provided with a workpiece insertion cover 19, and the surface of the workpiece insertion cover 19 is provided with a sealing access door 191.

[0040] An upper protective cover 192 is provided at the top of the outer frame cover 13 , and a sensing mechanism 4 is provided at the middle of the top of the upper protective cover 192 .

[0041] The sensing mechanism 4 includes an ultrasonic scanning seat 41 set up on the top surface of the upper protective cover 192, and sensing strips 42 for sensing are arranged on both sides of the ultrasonic scanning seat 41 in sequence. The ultrasonic receiving end at the bottom of the ultrasonic scanning seat 41 is set for sensing with the bottom surface of the upper protective cover 192.

[0042] In this embodiment: a display screen 43 is provided on the side wall of the upper protective cover 192, and a workpiece vibration shape image is displayed on the surface of the display screen 43.

[0043] A connecting base 44 is vertically installed at one corner of the top of the upper protective cover 192, an alarm indicator light tube 45 is vertically installed in the middle of the top of the connecting base 44, and a lathe vibration detection probe is installed at the bottom of the alarm indicator light tube 45, which is used to detect the position of the tool head during turning processing.

[0044] The display screen 43 is used to display the information detected by the ultrasonic scanning seat 41 through ultrasonic perception.

[0045] like Figure 4 As shown, in this embodiment: the variable measuring mechanism 2 is composed of an arc guide rail 21, a linear motion motor 22, a self-folding bracket 23 and a sliding seat 24.

[0046] The arc guide rail 21 is connected to the bottom side of the upper protective top cover 192 in sequence, the linear moving motor 22 is arranged in sequence on the bottom surface of the arc guide rail 21, and two self-folding brackets 23 are provided, which are respectively installed on the bottom surface of the arc guide rail 21. The end of one of the self-folding brackets 23 is provided with a three-dimensional dynamic scanner 231 for dynamic detection, and the three-dimensional dynamic scanner 231 has a built-in dynamic detection image recognition lens 232.

[0047] The two self-folding brackets 23 are both linearly moved along the arc-shaped guide rail 21 by the linear movement motor 22 .

[0048] The end of the self-folding bracket 23 on the other side is also equipped with a dynamic vision sensing mechanism 5 for dynamic vision capture.

[0049] The self-folding support 23 and the three-dimensional dynamic scanner 231 are used to scan the information of the operation stage. In addition, in order to change the direction and position of the scanning path, the surface of the arc guide rail 21 is automatically moved.

[0050] During the lathe processing stage, the monitoring of various parameters generated by turning, drilling or other processing is carried out by relying on the arc guide rail 21, as the connection movement of the self-folding bracket 23, through the power supply of the linear moving motor 22, and the intelligent control of the PLC controller 111, to intelligently capture information during the dynamic operation of the machine tool. Then, through the captured motion variable measurement, the mechanical equipment of each CNC lathe turning production is reversely controlled to optimize the motion variables.

[0051] The three-dimensional dynamic scanner 231 directly illuminates the workpiece itself during the production and cutting stage, and the dynamic detection image recognition lens 232, as the detection of the three-dimensional dynamic scanner 231, can further achieve dynamic changes in the shape of the processed workpiece (presenting an image model with a gradient of red, yellow and blue).

[0052] like Figure 4 and 5 As shown, the dynamic vision sensing mechanism 5 includes a dynamic vision sensor 51 installed on the side wall of another self-folding bracket 23, and a plurality of lens recognition brackets 52 are provided at the end of the dynamic vision sensor 51. A connecting seat is provided on the surface of the lens recognition bracket 52, and an arc bracket 53 for support is provided at the end of the connecting seat. An adjustment bracket 54 for support is provided on the side wall of the arc bracket 53, and a first sensing probe 55 for workpiece scanning detection is provided at the end of the adjustment bracket 54.

[0053] After the arc-shaped bracket 53 is connected to the induction coil, the support of the bracket 54 is adjusted, and the object to be processed and identified is determined according to the analysis lens 56.

[0054] In this embodiment: a plurality of analysis lenses 56 are arranged in sequence on the surface of the first sensing probe 55, and connecting bases 57 for connection are cross-arranged between the plurality of analysis lenses 56, and two arc-shaped regulating frames 58 are installed in sequence on the side wall surface of the arc-shaped bracket 53, and connecting vertical poles 59 for support are respectively provided on both sides of the top of the two arc-shaped regulating frames 58, and a detection base 591 is fixedly installed on the surface of the connecting vertical pole 59, and a temperature detector 592 for identifying the temperature is provided on the top surface of the detection base 591, and a second sensing probe 593 for adjustment is provided on the end surface of the temperature detector 592 in sequence, and the second sensing probe 593 is integrated with a vibration curvature identifier 594, and the vibration curvature identifier 594 is provided with a polarization identification chip 595.

[0055] The temperature detector 592 and the second sensing probe 593 used work together to improve the analysis and identification of vibrations achieved by the temperature detection state. The vibration arc identifier 594 is used to accurately acquire vibration data, and the polarization identification chip 595 is used for analysis of vibration information.

[0056] In this embodiment: a vibration detection plate 241 for vibration detection is provided in the middle of the bottom end of the sliding seat 24, and a plurality of vibration analyzers 242 for identification are cross-arranged on the surface of the vibration detection plate 241, and a baffle for separation is cross-arranged in the middle of the plurality of vibration analyzers 242. A thermal imager 243 for ambient temperature detection is also installed on the bottom surface of the arc guide rail 21, and a thermal imaging seat 244 is installed at the bottom of the thermal imager 243. The thermal imaging seat 244, the second sensing probe 593, the vibration arc identifier 594, the dynamic visual sensor 51, the first sensing probe 55, the vibration detection probe and the recording end of the dynamic detection image recognition lens 232 are all relative to the detection viewing angles of the machine tool processing mechanism 3.

[0057] The image recognition of the adopted thermal imager 243 and the image input between the thermal imaging seats 244 facilitate the acquisition and presentation of thermal information.

[0058] By combining the function of the dynamic visual sensor mechanism 5, the shape processing changes of the processing object can be dynamically identified, and the changes in the appearance cutting process can be accurately controlled to maintain the consistency of the input of the actual appearance. First, the workpiece is captured according to the dynamic visual sensor 51. The captured workpiece has a green frame and other red and blue identification frames, which are located in different positions of the processing workpiece. The implementation principle of these frames is through the analysis lens 56 and the first perception probe 55 for precise capture.

[0059] The green color indicates the detection of the analysis lens 56. When the workpiece approaches the recognition area, it is located by the analysis lens 56, and the presented range is selected and observed through a green frame on the display.

[0060] The blue identification is the product's own vibration status information determined by the combination of the vibration curvature identifier 594 and the polarization identification chip 595. It can see more detailed vibration changes of the product during the processing stage, as well as the curvature correction data information between the polarization of the machine itself (the vibration of the machine itself is obtained by using the ultrasonic scanning seat 41 to scan downward for detection and analysis to obtain the specific ultrasonic vibration data, so that the data matching degree of the two is constant, achieving the effect of polarization correction and data calibration).

[0061] Red recognition is the temperature information generated when the tool head cuts the workpiece. The information is obtained through the cooperation of the temperature detector 592 and the thermal imaging seat 244 to achieve the imaging cooling image (a contour film-like video image from blue to orange and then to red). During production, the images of different perspectives can be switched at any time. This perspective image is automatically summarized and organized by the PLC program, which can be automatic or manual to assist people in making accurate data references and improve the precision characteristics of production.

[0062] Moreover, the viewing angle is adjustable, and the self-folding bracket 23 is used for storing, folding, adjusting and folding the probe during the detection phase.

[0063] After obtaining the above data, the machine can automatically make operational and production judgments beyond ordinary people to assist workers in processing more precise workpieces that are not affected by the environment, further improving the processing precision of the machine tool itself.

[0064] like 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 groove 16, and a five-axis cutting clamping disk 32 is driven by a motor in the middle of the five-axis turning seat 31. The surface of the five-axis cutting clamping disk 32 is provided with clamping fixtures 33 around, and the four corners of the clamping fixture 33 are all installed with adjustment bases 34 for adjustment. The middle part of the adjustment base 34 is provided with a clamping base 35 for adjustment, and a transverse cutting rod 36 is transversely installed in the middle of the bottom end of the clamping base 35, and the other end of the transverse cutting rod 36 is telescopically arranged with a pneumatic cylinder 37.

[0065] The adopted transverse cutting rod 36 is controlled by the pneumatic cylinder 37, which further promotes that the machine tool processing is more stable and the cutting effect is more accurate.

[0066] like Figure 7As shown, the turning mechanism 6 includes a linear push bracket 61 placed on the inner bottom surface of the outer frame cover 13, a push screw 62 is installed horizontally in the middle of the linear push bracket 61, and rubber buffer pads 63 are installed at the four corners of the bottom of the push screw 62.

[0068] 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, and a second driving motor 73 with the output end facing downward is provided in the middle of the top of the drilling bracket 72.

[0069] The output end of the second driving motor 73 is connected to the driving screw 75 through a coupling 74, and the driving screw 75 is threadedly matched with the fitting support plate 76. A drilling motor 77 is installed on the surface of the fitting support plate 76, and the bottom rotating end of the drilling motor 77 corresponds to the surface position of the access base 693.

[0070] The coupling 74 and the drilling motor 77 cooperate with each other to facilitate further processing of some structures that require drilling operations.

[0072] By using the adjustment panel 134 and the control console 131 to adapt to each other, the recognition of the corresponding computer is achieved.

[0073] The workpiece is placed on the surface of the access base 693, and the position of the square support plate 64 is changed by the cyclic movement of the push screw 62. When the drilling end is cutting, the position of the cutting end is constantly changed, and the workpiece is positioned and cut by accessing the base 693. In addition, for the auxiliary production of multiple axes, by controlling the CNC machine tool, as the dynamic production of the corresponding machine tool, the disk surface positioning matching of the five-axis turning seat 31 and the five-axis cutting clamping disk 32 is utilized, as the position change between the tools that need to be cut, according to the mutual cooperation of the clamping fixture 33 and the clamping base 35, cutting and clamping are performed at the same time to weaken the vibration arc of the cutting drill during drilling and cutting.
