Description

Technical Field

[0001] The present invention relates to the technical field of machining machine tools, and in particular to a mechanical vibration measuring device and a measuring method for precision machining machine tools. Background Art

[0002] Processing machine tools are equipment used for cutting, grinding, milling, drilling, turning and other metal or other material processing. They are very important tools in modern manufacturing and are used to produce various parts and components. They are widely used in automobile, aviation, electronics, mold, shipbuilding and other industries. Machine tools are usually composed of power system, control system, feed system, workbench system and cutting tools.

[0003] During the operation of precision machining machines, mechanical vibrations may have an adverse effect on machining accuracy, surface quality and machine tool life. Existing measuring devices use some sensors to detect the detection parts, which requires manual installation, is time-consuming, and needs to be disassembled after the detection is completed. In addition, existing measuring devices cannot detect the surface of rotating circular workpieces or machining machines at the same time. It requires the combination of two measuring devices to achieve this. In addition, the existing measuring devices are fixed on the outer surface of the machining machine. The vibration generated when the machining machine is running will drive the measuring device to vibrate, which can easily cause inaccurate detection results of the measuring device and easily cause damage to the measuring device over a long period of time. Summary of the invention

[0004] Based on the existing measuring devices, some sensors are used to detect the detection parts, which need to be installed manually and are time-consuming. Two measuring devices need to be combined to detect different parts. The vibration generated when the processing machine tool is running will drive the measuring device to vibrate, which is easy to cause inaccurate detection results of the measuring device. At the same time, the measuring device is easily damaged for a long time. The present invention proposes a mechanical vibration measuring device and a measuring method for precision processing machine tools.

[0005] The present invention provides a mechanical vibration measuring device for a precision machining machine tool, comprising a machining machine tool and a base, wherein the base is arranged on the outer side of the machining machine tool, and further comprises a shock absorbing device, an adjusting device and a measuring device.

[0006] The shock absorbing device is located on the upper surface of the base and performs shock absorption on the measuring device. The shock absorbing device includes a shock absorbing frame and a shock absorbing connecting rod. The lifting and lowering of the shock absorbing frame drives the shock absorbing connecting rod to deflect.

[0007] The adjusting device is located on the upper surface of the shock-absorbing frame and adjusts the position of the measuring device. The adjusting device includes a displacement adjusting mechanism and a steering adjusting mechanism. The displacement adjusting mechanism drives the measuring device to move, and the steering adjusting mechanism drives the measuring device to steer.

[0008] The measuring device is located on the outer surface of the adjusting device and detects the vibration of the machine tool. The measuring device includes a curling mechanism and a detecting mechanism. The curling mechanism drives the detecting mechanism to curl into an annular shape, and the detecting mechanism detects the vibration of the machine tool.

[0009] Preferably, the shock-absorbing device further includes a telescopic rod. The telescopic rod is fixedly installed on the upper surface of the base. The upper surface of the telescopic rod is fixedly installed with the lower surface of the shock-absorbing frame. One ends of the shock-absorbing frame and the upper surface of the base are hinged to one ends of a plurality of shock-absorbing connecting rods through pins. One end of the shock-absorbing connecting rod is hinged with a shock-absorbing slider through a pin. A buffer magnet is fixedly installed on the lower surface of the shock-absorbing frame and the upper surface of the base through a connecting block.

[0010] Through the above technical solution, the telescopic rod facilitates buffering the vibration generated by the shock-absorbing frame. When the shock-absorbing frame is vibrated, the shock-absorbing connecting rod can deflect and then push the shock-absorbing slider to move. The magnetic poles of the two buffer magnets are the same. After the magnetic fields repel each other, the buffer magnet located above can descend and then reset to achieve the purpose of buffering.

[0011] Preferably, a buffer limiting frame is slidably sleeved on the outer surface of the connecting block. The outer surface of the shock-absorbing slider is slidably inserted into the inner wall of the buffer limiting frame. A shock-absorbing spring is fixedly installed on the outer surface of the shock-absorbing slider. One end of the shock-absorbing spring is fixedly installed on the inner wall of the buffer limiting frame.

[0012] Through the above technical solution, in order to facilitate shock-absorbing work and the quick reset of the shock-absorbing slider, the generated vibration can be absorbed by the compression of the shock-absorbing spring.

[0013] Preferably, the displacement adjusting mechanism further includes a lifting hydraulic cylinder. The lower surface of the lifting hydraulic cylinder is fixedly installed on the upper surface of the shock-absorbing frame. One end of the piston rod of the lifting hydraulic cylinder is fixedly installed with a lifting platform. The upper surface of the lifting platform is fixedly installed with a moving component. A lifting slider is threadedly connected to the outer surface of the double-headed lead screw of the moving component. One end of the lifting slider is slidably sleeved on one end of the limiting rod of the moving component.

[0014] Through the above technical solution, the moving part includes a double-headed lead screw, a motor for driving the rotation of the double-headed lead screw, and a limiting rod. The double-headed lead screw can drive the lifting slider to move relatively or in the opposite direction, so as to facilitate the adjustment of the distance between the two lifting sliders, enabling the detection device to adapt to various positions of the processing machine tool and increasing the practicality.

[0015] Preferably, the steering adjustment mechanism further includes a moving frame, the moving frame is fixedly installed on the upper surface of the lifting slider, a lifting frame with a gear is slidably inserted on the outer surface of the moving frame, a roller is rotatably connected to the outer surface of the lifting frame through a bearing, a lifting track plate is fixedly installed on the upper surface of the lifting platform, and the outer surface of the roller is slidably connected to the inner wall of the lifting track plate.

[0016] Through the above technical solution, in order to drive the detection device to turn through the movement of the lifting slider, after the movement of the lifting slider can drive the lifting frame to move, the roller rolls within the track on the lifting track plate, and then the lifting frame is pulled to descend on the moving frame. There are raised points in the upper groove of the lifting track plate, which is convenient for the roller to move along the set track direction, so that it can first descend and then move horizontally, and then rise and move along the horizontal track above, so that the detection device can turn after moving. When moving back, the detection device maintains the state after turning.

[0017] Preferably, a steering rod with a gear is rotatably connected to the outer surface of the moving frame through a bearing, the gear of the steering rod meshes with the gear of the lifting frame, a steering rack is fixedly installed on the upper surface of the lifting track plate, a steering gear is fixedly installed at one end of the steering rod, the steering gear meshes with the steering rack, and a telescopic hydraulic cylinder is fixedly installed at one end of the steering rod.

[0018] Through the above technical solution, after the gear of the steering rod meshes with the gear of the lifting frame, the gear of the steering rod can be self-locked to prevent the steering rod from rotating by itself without driving. After the steering gear descends, it can mesh with the steering rack, so that the rotation of the steering gear can drive the steering rod to turn, and the upper and lower surfaces inside the processing machine tool can be measured.

[0019] Preferably, the curling mechanism includes a support frame. One support frame is fixedly installed at one end of the piston rod of the telescopic hydraulic cylinder. One end of the support frame is hinged to a curling hydraulic cylinder through a pin shaft. One ends of the other support frames are hinged to the outer surface of the curling hydraulic cylinder through a pin shaft. A curling link is hinged to the outer surface of the support frame through a pin shaft. One end of the piston rod of the curling hydraulic cylinder is hinged to one ends of the two curling links through a pin shaft.

[0020] Through the above technical solution, both ends between the two support frames are hinged to one end of the curling hydraulic cylinder through a pin shaft. The curling hydraulic cylinder is used to push the curling connecting rod to deflect, so that multiple support frames can be curled into a ring shape, which is convenient for vibration measurement of a cylindrical workpiece or a positioning rod for positioning the workpiece.

[0021] Preferably, the detection mechanism further includes a limit groove body which is fixedly installed on the outer surface of the support frame. A driving gear ring is slidably inserted into the inner wall of the limit groove body. A transmission gear set is rotatably connected to the inner wall of the support frame through a bearing. The driving gear ring meshes with the gears of the transmission gear set. A driving motor is fixedly installed on the outer surface of one of the support frames. One end of the output shaft of the driving motor is fixedly installed with one end of the transmission gear set.

[0022] Through the above technical solution, the transmission gear set can rotate under the drive of the driving motor, drive the driving gear ring engaged therewith to rotate, and thus can push other driving gear rings to rotate. Multiple driving gear rings form a complete gear ring, which can drive the transmission gear set engaged therewith to rotate.

[0023] Preferably, a detection rack is slidably inserted into the outer surface of the support frame. The detection rack meshes with the gears of the transmission gear set. A detection sensor group is fixedly installed on the outer surface of the detection rack. The detection sensor group includes an eddy current sensor, a vibration sensor and a speed sensor.

[0024] Through the above technical solution, the rotation of the transmission gear set can drive the detection rack engaged therewith to move, so as to adjust the positions of the sensors in the detection sensor group.

[0025] A measuring method for a mechanical vibration measuring device for a precision machining machine tool proposed by the present invention includes the following steps:

[0026] S1: After pushing the base to the window of the machining machine tool, the lifting hydraulic cylinder drives the lifting platform to rise. By starting the moving component to adjust the positions of the two side sliders, the position of the telescopic hydraulic cylinder can be adjusted. When it is necessary to detect a circular workpiece or a circular fixture clamped by the machining machine tool, the telescopic hydraulic cylinder on the support frame pushes the curling connecting rod upward, and the curling connecting rod drives the support frame to deflect, so that the curling mechanism unfolded into a straight line curls inward into a ring shape;

[0027] S2: After sleeving the support frame at the position to be detected, start the driving motor to drive the transmission gear set fixedly installed therewith. After the transmission gear set drives the driving gear ring engaged therewith to rotate in the limit groove body, drive the other driving gear rings to rotate, so as to drive the detection rack to lift, so that some sensors of the detection sensor group on the detection rack contact the detection piece, and after the other part approaches the detection piece, start the processing machine tool, and the detection sensor group detects the vibration of the detection piece;

[0028] S3: At the same time, after the base is vibrated by the processing machine tool, the shock absorption frame vibrates, the shock absorption frame drives the telescopic rod to slightly expand and contract, drives the shock absorption connecting rod to deflect and then pushes the slider to move in the buffer limit frame, pulls the shock absorption spring, and at the same time drives the buffer limit frame to descend. The connecting block on the shock absorption frame descends, driving the buffer magnet to descend. The same-sex repulsion between two opposite buffer magnets enables reset after descending to complete the shock absorption work;

[0029] S4: When it is necessary to detect the flat position of the processing machine tool, the curling hydraulic cylinder resets, drives the curling connecting rod to deflect, so that the support frame unfolds into a horizontal shape. After the double-headed lead screw of the moving part rotates, it drives the lifting slider to move. The lifting slider drives the moving frame to move. After the rollers on the lifting frame move along the track of the lifting track plate, pull the lifting frame to descend on the moving frame, so that the steering gear on the steering rod can mesh with the steering rack. The movement of the lifting slider drives the steering rod to deflect, so that the detection head of the detection sensor group on the support frame faces downward, which is convenient for contacting the detection part of the processing machine tool, and the roller can be reset along the upper part of the lifting track plate, so that the steering gear disengages from the steering rack.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. By setting the shock absorption device, the measuring device can be shock-absorbed, reducing the vibration generated during the operation of the processing machine tool from being transmitted to the ground and affecting the base, thereby affecting the detection effect of the measuring device. The telescopic rod facilitates buffering the vibration generated by the shock absorption frame. When the shock absorption frame is vibrated, the shock absorption connecting rod can deflect and then push the shock absorption slider to move. The magnetic poles of the two buffer magnets are the same, and after the magnetic fields repel each other, the buffer magnet located above can reset after descending, achieving the purpose of buffering. This solves the technical problems that the existing measuring device detects the detection part through some sensors, the vibration generated during the operation of the processing machine tool will drive the measuring device to vibrate, which is likely to cause inaccurate detection results of the measuring device, and at the same time, the measuring device is likely to be damaged after a long time.

[0032] 2. By setting an adjusting device, the measuring device can be adjusted in terms of steering and displacement, facilitating the measurement of multiple positions on the processing machine tool, so as to obtain accurate vibration measurement values. After the lifting slider moves, it can drive the lifting frame to move. Then, after the roller rolls within the track of the lifting track plate, the lifting frame is pulled to descend on the moving frame. After the steering gear descends, it can mesh with the steering rack, so that the rotation of the steering gear can drive the steering rod to steer, enabling the measurement of the upper and lower surfaces inside the processing machine tool. Through the cooperation of the moving component and the lifting hydraulic cylinder, the measuring device can be driven to move to the measurement position, thereby increasing the practicality.

[0033] 3. By setting a measuring device, the vibration of different positions of the processing machine tool can be measured. One end of the curling hydraulic cylinder is hinged to both of the two support frames through a pin shaft. By pushing the curling connecting rod to deflect through the curling hydraulic cylinder, multiple support frames can be curled to form a ring, facilitating the vibration measurement of cylindrical workpieces or positioning rods for positioning workpieces. After the curling hydraulic cylinder retracts, it drives the curling connecting rod to push the support frame to deflect, causing the ring-shaped support frame to open and be distributed in a horizontal state, enabling the vibration measurement of the parts on the plate surface of the processing machine tool. Thus, it is not necessary to cooperate with multiple measuring devices, solving the technical problems of the existing measuring devices that need to be installed manually by some sensors for the detection parts, consuming time, and requiring the combination of two measuring devices to detect different parts.

Specific embodiments

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] Referring to Figures 1 - 8 , a mechanical vibration measuring device for a precision machining machine tool 1 includes a machining machine tool 1 and a base 11. The base 11 is arranged on the outer side of the machining machine tool 1, and further includes a shock-absorbing device, an adjusting device, and a measuring device.

[0045] As Figures 2 - 3 shown, in order to reduce the influence of the vibration generated by the machining machine tool 1 on the measuring device, the shock-absorbing device is located on the upper surface of the base 11 and shock-absorbs the measuring device. The shock-absorbing device includes a shock-absorbing frame 2 and a shock-absorbing connecting rod 22. The lifting of the shock-absorbing frame 2 drives the shock-absorbing connecting rod 22 to deflect.

[0046] Specifically, in order to dampen the shock of the shock absorber 2, the shock absorption device further includes a telescopic rod 21. The telescopic rod 21 is fixedly installed on the upper surface of the base 11. The telescopic rod 21 supports the shock absorber 2, and the upper surface of the telescopic rod 21 is fixedly installed with the lower surface of the shock absorber 2. In order to dampen the vibration received by the shock absorber 2, one end of the lower surface of the shock absorber 2 and the upper surface of the base 11 are respectively hinged to one end of a plurality of shock absorption connecting rods 22 by a pin shaft. One end of the shock absorption connecting rod 22 is hinged with a shock absorption slider 23 by a pin shaft. A buffer magnet 24 is fixedly installed on the lower surface of the shock absorber 2 and the upper surface of the base 11 through a connecting block. The magnetic poles of the two buffer magnets 24 are the same, and like poles repel each other. Therefore, after the buffer magnet 24 on the shock absorber 2 descends, the magnetic field generated is the same as that of the buffer magnet 24 below, and after repulsion, it can be reset.

[0047] Specifically, in order to facilitate the reset of the shock absorption slider 23, a buffer limit frame 25 is slidably sleeved on the outer surface of the connecting block. The outer surface of the shock absorption slider 23 is slidably inserted into the inner wall of the buffer limit frame 25. A shock absorption spring 26 is fixedly installed on the outer surface of the shock absorption slider 23, and one end of the shock absorption spring 26 is fixedly installed on the inner wall of the buffer limit frame 25; in order to facilitate the shock absorption work and at the same time facilitate the quick reset of the shock absorption slider 23, the vibration generated can be absorbed by the compression of the shock absorption spring 26.

[0048] As Figures 4 - 6 shown, in order to place the adjustment device on the upper surface of the shock absorber 2 and adjust the position of the measuring device, the adjustment device includes a displacement adjustment mechanism and a steering adjustment mechanism. The displacement adjustment mechanism drives the measuring device to move, and the steering adjustment mechanism drives the measuring device to turn.

[0049] Specifically, in order to adjust the height of the measuring device, the displacement adjustment mechanism further includes a lifting hydraulic cylinder 3. The lower surface of the lifting hydraulic cylinder 3 is fixedly installed on the upper surface of the shock absorber 2. One end of the piston rod of the lifting hydraulic cylinder 3 is fixedly installed with a lifting platform 31. A moving component 32 is fixedly installed on the upper surface of the lifting platform 31. The moving component 32 includes a double-headed lead screw, a motor for driving the double-headed lead screw to rotate, and a limiting rod. A lifting slider 33 is threadedly connected to the outer surface of the double-headed lead screw of the moving component 32, and one end of the lifting slider 33 is slidably sleeved with one end of the limiting rod of the moving component 32.

[0050] Specifically, in order to drive the measuring mechanism to make steering adjustments, the steering adjustment mechanism further includes a moving frame 4. The moving frame 4 is fixedly installed on the upper surface of the lifting slider 33. A lifting frame 41 with a gear is slidably inserted on the outer surface of the moving frame 4. A roller 42 is rotatably connected to the outer surface of the lifting frame 41 through a bearing. A lifting track plate 43 is fixedly installed on the upper surface of the lifting platform 31. The outer surface of the roller 42 is slidably connected to the inner wall of the lifting track plate 43. Protrusions are provided in the upper groove of the lifting track plate 43 to facilitate the movement of the roller 42 along the set track direction, so that it can first descend and then move horizontally, and then rise and move along the horizontal track above, so that the detection device can move and then turn. When moving back, the detection device maintains the turned state.

[0051] Specifically, in order to drive the steering rod 44 to turn, a steering rod 44 with a gear is rotatably connected to the outer surface of the moving frame 4 through a bearing. The gear of the steering rod 44 meshes with the gear of the lifting frame 41. A steering rack 45 is fixedly installed on the upper surface of the lifting track plate 43. A steering gear 46 is fixedly installed at one end of the steering rod 44. The steering gear 46 meshes with the steering rack 45. A telescopic hydraulic cylinder 47 is fixedly installed at one end of the steering rod 44.

[0052] As Figures 7 - 8 shown, in order to measure the inside of the processing machine tool 1, the measuring device is located on the outer surface of the adjusting device and detects the vibration of the processing machine tool 1. The measuring device includes a curling mechanism and a detecting mechanism. The curling mechanism drives the detecting mechanism to curl into an annular shape, and the detecting mechanism detects the vibration of the processing machine tool 1.

[0053] Specifically, in order to drive the position of the measuring mechanism to be adjusted, the curling mechanism includes a support frame 5. One support frame 5 is fixedly installed at one end of the piston rod of the telescopic hydraulic cylinder 47. One end of the support frame 5 is hinged to a curling hydraulic cylinder 51 through a pin shaft. One ends of the other support frames 5 are hinged to the outer surface of the curling hydraulic cylinder 51 through a pin shaft. A curling link 52 is hinged to the outer surface of the support frame 5 through a pin shaft. One end of the piston rod of the curling hydraulic cylinder 51 is hinged to one ends of the two curling links 52 through a pin shaft. One ends of the two support frames 5 are both hinged to one end of the curling hydraulic cylinder 51 through a pin shaft. By pushing the curling link 52 to deflect through the curling hydraulic cylinder 51, multiple support frames 5 can be curled into an annular shape, which is convenient for measuring the vibration of a cylindrical workpiece or a positioning rod for positioning the workpiece.

[0054] Specifically, in order to measure the machining tool 1, the detection mechanism further includes a limit groove body 6 which is fixedly installed on the outer surface of the support frame 5. A driving gear ring 61 is slidably inserted into the inner wall of the limit groove body 6. A transmission gear set 62 is rotatably connected to the inner wall of the support frame 5 through a bearing. The driving gear ring 61 meshes with the gears of the transmission gear set 62. A driving motor 63 is fixedly installed on the outer surface of one support frame 5. One end of the output shaft of the driving motor 63 is fixedly installed with one end of a transmission gear set 62. The transmission gear set 62 can rotate under the drive of the driving motor 63, driving the meshing driving gear ring 61 to rotate, so as to drive other driving gear rings 61 to rotate. A plurality of driving gear rings 61 form a complete gear ring, thereby driving the transmission gear set 62 meshing with it to rotate.

[0055] Specifically, in order to facilitate fitting or approaching the measurement target, a detection rack 64 is slidably inserted into the outer surface of the support frame 5. The detection rack 64 meshes with the gears of the transmission gear set 62. A detection sensor group 65 is fixedly installed on the outer surface of the detection rack 64. The detection sensor group 65 includes an eddy current sensor, a vibration sensor and a speed sensor.

[0056] As Figures 1 - 8 shown, a measurement method of a mechanical vibration measurement device for a precision machining tool proposed by the invention includes the following steps:

[0057] S1: After pushing the base 11 to the window of the machining tool 1, the lifting hydraulic cylinder 3 drives the lifting platform 31 to rise. By starting the moving member 32 to adjust the positions of the two side sliders, the position of the telescopic hydraulic cylinder 47 can be adjusted. When it is necessary to detect the circular workpiece or circular fixture clamped by the machining tool 1, the telescopic hydraulic cylinder 47 on the support frame 5 pushes the curling link 52 upward. The curling link 52 drives the support frame 5 to deflect, so that the curling mechanism unfolded into a straight line curls inward into an annular shape.

[0058] S2: After sleeving the support frame 5 at the position to be detected, start the driving motor 63 to drive the transmission gear set 62 fixedly installed therewith. The transmission gear set 62 drives the meshing driving gear ring 61 to rotate in the limit groove body 6, and then drives the other driving gear rings 61 to rotate, so as to drive the detection rack 64 to move up and down, so that some sensors of the detection sensor group on the detection rack 64 contact the detection piece, and the other part approaches the detection piece. Then start the machining tool 1, and the detection sensor group 65 detects the vibration of the detection piece.

[0059] S3: After the base 11 is vibrated by the processing machine tool 1, the shock-absorbing frame 2 vibrates. The shock-absorbing frame 2 drives the telescopic rod 21 to slightly expand and contract, drives the shock-absorbing connecting rod 22 to deflect, then pushes the slider to move within the buffer limiting frame 25, pulls the shock-absorbing spring 26, and at the same time drives the buffer limiting frame 25 to descend. The connecting block on the shock-absorbing frame 2 descends, driving the buffer magnet 24 to descend. The like poles of the two opposite buffer magnets 24 repel each other, enabling reset after descending and completing the shock-absorbing work;

[0060] S4: When it is necessary to detect the flat position of the processing machine tool 1, the curling hydraulic cylinder 51 resets. After driving the curling connecting rod 52 to deflect, the support frame 5 is unfolded into a horizontal shape. Then, after the double-headed lead screw of the moving component 32 rotates, it drives the lifting slider 33 to move. The lifting slider 33 drives the moving frame 4 to move. The rollers 42 on the lifting frame 41 move along the track of the lifting track plate 43. After pulling the lifting frame 41 to descend on the moving frame 4, the steering gear 46 on the steering rod 44 can be engaged with the steering rack 45. The movement of the lifting slider 33 drives the steering rod 44 to deflect, so that the detection head of the detection sensor group 65 on the support frame 5 faces downward, facilitating contact with the detection part of the processing machine tool 1. The rollers 42 can reset along the upper part of the lifting track plate 43, so that the steering gear 46 disengages from the steering rack 45.

[0061] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
