[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.

The displacement adjusting mechanism drives the measuring device to move, and the steering adjusting mechanism drives the measuring device to turn.

[0008] The measuring device is located on the outer surface of the adjusting device and detects the vibration of the processing machine. The measuring device includes a curling mechanism and a detecting mechanism.

[0010] Through the above technical solution, the vibration generated by the shock-absorbing frame can be buffered by the telescopic rod. When the shock-absorbing frame is vibrated, the shock-absorbing connecting rod can be deflected to push the shock-absorbing slider to move. The magnetic poles of the two buffer magnets are the same, and the magnetic fields repel each other, so that the buffer magnet located above can be reset after it drops, thereby achieving the purpose of buffering.

[0014] Through the above technical solution, the moving parts include a double-headed screw, a motor that drives the double-headed screw to rotate, and a limit rod. The double-headed screw can drive the lifting slider to move relative or oppositely, so that the distance between the two lifting sliders can be easily adjusted, so that the detection device can adapt to various positions of the processing machine tool and increase practicality.

[0016] Through the above technical scheme, in order to drive the detection device to turn by the movement of the lifting slider, the movement of the lifting slider can drive the lifting frame to move, and after the roller rolls in the track on the lifting track plate, the lifting frame is pulled down on the moving frame, and a protrusion is set in the groove at the upper end of the lifting track plate to facilitate 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 upper horizontal track, so that the detection device can turn after moving, and when moving back, the detection device maintains the turned state.

[0018] Through the above technical solution, after the gear of the steering rod is meshed 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 being driven. After the steering gear is lowered, it can be meshed with the steering rack, so that the rotation of the steering gear can drive the steering rod to steer, and the internal upper and lower surfaces of the processing machine tool can be measured.

[0019] Preferably, the curling mechanism includes a support frame, one of the support frames is fixedly mounted on one end of the piston rod of the telescopic hydraulic cylinder, one end of the support frame is hinged to the curling hydraulic cylinder through a pin, and one end of the other support frame is hinged to the outer surface of the curling hydraulic cylinder through a pin, the outer surface of the support frame is hinged to a curling connecting rod through a pin, and one end of the piston rod of the curling hydraulic cylinder is hinged to one end of the curling connecting rod on both sides through a pin.

[0020] Through the above technical solution, the two support frames are hinged to one end of the curling hydraulic cylinder through a pin shaft, and the curling hydraulic cylinder pushes the curling connecting rod to deflect, so that multiple support frames can be curled to form a ring, which is convenient for vibration measurement of cylindrical workpieces or positioning rods for positioning workpieces.

[0021] Preferably, the detection mechanism also includes a limit groove body, which is fixedly installed on the outer surface of the support frame, and the inner wall of the limit groove body is slidably inserted with a driving gear ring, the inner wall of the support frame is rotatably connected with a transmission gear set through a bearing, and the driving gear ring is meshed with the gear of the transmission gear set, and a driving motor is fixedly installed on the outer surface of the support frame, and one end of the output shaft of the driving motor is fixedly installed on 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, driving the driving gear ring meshing with it to rotate, thereby driving other driving gear rings to rotate. Multiple driving gear rings form a complete gear ring, which can drive the transmission gear set meshing with it to rotate.

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

[0024] Through the above technical solution, by transmitting the rotation of the gear set, the detection rack meshing therewith can be driven to move, so that the position of the sensor in the detection sensor group can be adjusted.

[0025] The present invention provides a method for measuring mechanical vibration of a precision machining machine tool, comprising the following steps: S1: After the base is pushed to the window of the processing machine, the lifting hydraulic cylinder drives the lifting platform to rise, and the positions of the sliders on both sides are adjusted by the moving parts, and the position of the telescopic hydraulic cylinder can be adjusted. When it is necessary to detect the circular workpiece or circular fixture clamped by the processing machine, the curling connecting rod is pushed upward by the telescopic hydraulic cylinder on the support frame, and the curling connecting rod drives the support frame to deflect, so that the curling mechanism unfolded into a straight line is curled inward into a ring shape; S2: After the support frame is sleeved at the position to be detected, the driving motor is started to drive the transmission gear set fixed thereto, and the transmission gear set drives the driving gear ring meshing therewith to rotate in the limit groove body, and then drives the remaining driving gear rings to rotate, so as to drive the detection rack to rise and fall, so that part of the sensors of the detection sensor group on the detection rack contacts the detection part, and the other part is close to the detection part, and then the processing machine tool is started, and the detection sensor group detects the vibration of the detection part; S3: At the same time, after the base is vibrated by the processing machine, the shock absorbing frame vibrates, and the shock absorbing frame drives the telescopic rod to slightly extend and retract, drives the shock absorbing connecting rod to deflect, and then pushes the slider to move in the buffer limit frame, pulls the shock absorbing spring, and drives the buffer limit frame to descend at the same time. The connecting block on the shock absorbing frame descends, driving the buffer magnet to descend. The two opposite buffer magnets repel each other with the same polarity, and can be reset after descending, completing the shock absorbing work; S4: When it is necessary to detect the planar position of the processing machine, the curling hydraulic cylinder is reset, driving the curling connecting rod to deflect, so that the support frame is unfolded into a horizontal shape, and the double-headed screw of the moving part rotates, driving the lifting slider to move, and 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, the lifting frame is pulled down on the moving frame, so that the steering gear on the steering rod can engage 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 contact with the detection part of the processing machine, and the rollers can be reset along the top of the lifting track plate to release the engagement between the steering gear and the steering rack.

[0026] The beneficial effects of the present invention are: 1. By setting a shock-absorbing device, the measuring device can be damped, and the vibration generated by the processing machine tool during operation can be reduced and transmitted to the ground, which affects the base and thus affects the detection effect of the measuring device. The telescopic rod is used to buffer the vibration generated by the shock-absorbing frame. When the shock-absorbing frame is vibrated, the shock-absorbing connecting rod can be deflected and push the shock-absorbing slider to move. The two buffer magnets have the same magnetic poles, and after the magnetic fields repel each other, the buffer magnet located above can be reset after it drops, thereby achieving the purpose of buffering. This solves the problem that the existing measuring device detects the detection part through some sensors, and the vibration generated by the processing machine tool during operation will drive the measuring device to vibrate, which is easy to cause inaccurate detection results of the measuring device, and the technical problem that the measuring device is easy to be damaged for a long time.

[0027] 2. By setting the adjustment device, the steering and displacement of the measuring device can be adjusted, which is convenient for measuring multiple positions on the processing machine tool, so as to obtain accurate vibration measurement values. The movement of the lifting slider can drive the lifting frame to move, and after the roller rolls in the track on the lifting track plate, the lifting frame is pulled down on the moving frame. After the steering gear descends, it can engage with the steering rack, so that the rotation of the steering gear can drive the steering rod to steer, and the internal upper and lower surfaces of the processing machine tool can be measured. The cooperation of the moving parts and the lifting hydraulic cylinder can drive the measuring device to move to the measuring position, thereby increasing practicality.

[0028] 3. By setting up a measuring device, vibration measurement can be performed on different positions of the processing machine tool. The two support frames are hinged with one end of the curling hydraulic cylinder through a pin shaft. The curling hydraulic cylinder pushes the curling connecting rod to deflect, so that multiple support frames can be curled into a ring, which is convenient for 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, so that the ring-shaped support frame opens and is distributed in a horizontal state, which can perform vibration measurement on the panel parts of the processing machine tool, thereby eliminating the need for multiple measuring devices to cooperate, and solving the technical problems that the existing measuring devices use some sensors to detect the detection parts, which requires manual installation and is time-consuming, and requires two measuring devices to be combined to detect different parts.
