Abstract
The invention provides a mechanical wearing detection and alarm system comprising a mechanical body (1), an alarm device (2), a detection device (3) and a display and control device (4). The detection device (3) is arranged in a cavity (5) and is composed of two ends of a spring (32), and a mass block (31) and a pressure sensor (33) which are connected with the two ends of the spring (32). The cavity (5) is arranged in the blind hole of the mechanical body (1). The internal part of the cavity (5) is provided with anti-interference devices (34) like a vibration absorber and a filter. The pressure sensor (33) is connected with the display and control device (4) via a band-pass filter and an A/D converter. The display and control device (4) comprises software analysis and processing and hardware control modules. The alarm device (2) is connected with the mass block (31). A slide rheostat is controlled by change of mass of the mass block (31) so as to influence voltage of the two ends of a light-emitting diode.
Description
Technical field
Type of the present invention belongs to mechanical wear detection field, particularly a kind of detection of mechanical wear and warning system.
Background technology
Machinery in use, there will be a large amount of attrition, affects the precision of machining, causes the waste of resource, have impact on the benefit of industry.There are now many wear detectors, can report to the police when detecting that mechanical wear to a certain extent, belong to the result that quantitative change causes, if but there is temporary condition such as because warning device goes wrong, not may apparent and effector can not be taken measures to ensure the precision of machining due to problem; And effector also wishes to sum up a series of Database Systems that can be for reference according to actual conditions, can obtain different materials, different service condition with the abrasion condition of time correlation, more excellent scheme even.
Summary of the invention
Emergency situations is there is in order to solve in mechanical use procedure, make quantitative change not cause warning device to warn to remind, cause the problem can not taking measures in time to ensure machining precision, in order to achieve the above object, type of the present invention is by the following technical solutions: type of the present invention comprises basic machine (1), warning device (2), pick-up unit (3), display and control unit (4), described pick-up unit (3) is placed in a cavity (5), is made up of the mass (31) of spring (32) two ends and connection thereof, pressure transducer (33); Described cavity (5) is positioned at basic machine (1) blind hole, and cavity (5) inside is containing the means for anti-jamming such as dashpot and wave filter (34); Described pressure transducer (33) is connected with display and control unit (4) by bandpass filter, A/D converter; Described display and control unit (4) comprises software analysis process, hardware control module; Described warning device (2) is connected with mass (31), and the change of mass (31) quality controls the forward voltage of light emitting diode.
The beneficial effect of inventing type: cavity adopts means for anti-jamming (34) to avoid causing interference to spring (32) and sensor (33) during mechanical vibration; Display and control unit (4) obtains the information collected by pressure transducer (33) in time, dynamic real time monitoring is had for change procedure, the data such as wear extent, service time can be obtained under different service condition, be convenient to compare obtain different condition under more excellent operational version, save cost or raise the efficiency, also reference is provided for later use, even if occur that emergency situations also can not delay effector for the control of integrality and decision-making.
accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of type of the present invention.
Embodiment
Type of the present invention comprises basic machine (1), warning device (2), pick-up unit (3), display and control unit (4), described pick-up unit (3) is placed in a cavity (5), by the mass (31) of spring (32) two ends and connection thereof, pressure transducer (33) is formed, mass is as cavity (5) plug mouth, and can consume owing to being worn, the change of mass (31) quality causes the movement of warning device (2) slide rheostat, thus control the voltage at light emitting diode two ends, non-electrical signal is converted to electric signal by pressure transducer (33), pass through wave filter, A/D converter is connected with display and control unit (4), described cavity (5) is positioned at basic machine (1) blind hole, the interference that cavity (5) inside produces spring (32), sensor (33) for eliminating mechanical vibration containing the means for anti-jamming such as dashpot and wave filter (34), described display and control unit (4) comprises software analysis process, hardware control module, also form a series of database in real time while monitoring wear condition.
In use, because wearing and tearing mass quality reduces, mass, the equilibrium state of spring and sensor is broken, the power that spring is subject to mass reduces and produces variable motion, non-electrical signal is converted into electric signal due to the change of power by pressure transducer, pass through bandpass filter, simulating signal is converted into digital signal by A/D converter, be input to display and control unit, the analyzing and processing of data is carried out by display device central processing unit, software simulation mass quality is about the curve map of time, can predict or show the time of the wearing and tearing upper limit intuitively, even if effector also can not be affected during warning device generation problem control presence states, when mass may wear to a certain amount of, diode current flow carries out warning to be reminded, and simultaneously in display and control unit, the mass quality of software simulation part reaches that wearing and tearing are upper also can send warning prompting in limited time, or automatically carries out Mechanical course by control module.
Claims (1)
1. the detection of a mechanical wear and warning system, comprise basic machine (1), warning device (2), pick-up unit (3), display and control unit (4), it is characterized in that: described pick-up unit (3) is placed in a cavity (5), be made up of the mass (31) of spring (32) two ends and connection thereof, pressure transducer (33); Described cavity (5) is positioned at basic machine (1) blind hole, and cavity (5) inside is containing the means for anti-jamming such as dashpot and wave filter (34); Described pressure transducer (33) is connected with display and control unit (4) by bandpass filter, A/D converter; Described display and control unit (4) comprises software analysis process, hardware control module; Described warning device (2) is connected with mass (31), and the change of mass (31) quality controls the voltage that slide rheostat affects light emitting diode two ends.
