Description
Technical field
The utility model relates to a kind of ball grinder, particularly a kind of ball grinder pressure real-time automatic intelligent monitoring protective device.
Background technology
Steel ball photosphere manufacturing procedure plays a part very important in the preceding road of steel ball work flow, steel ball ball base will carry out the decyclization band and be processed into spherical effect in this manufacturing procedure, in this working procedure processing process, the size of each processing cutting stage applied pressure is to production efficiency, the internal organizational structure of steel ball, products such as the surface of steel ball, the matter aspect plays decisive role, pressure lack of uniformity in the process and operators'skills situation, operating habit tends to cause occur in the course of processing high-voltage high-speed cutting phenomenon, the existence of this phenomenon, the one, to the machinery of lathe, electricly cause damage, applying of excessive pressure will increase the weight of load for a long time, base bearing to lathe, support, mechanisms such as gear will add galling, cause spindle eccentricity easily, cause base bearing to damage, gear teeth is gnawed bad, excessive pressure also can cause the vibration of lathe, drive reducing gear rocks thereupon, and then cause the vibration of main motor, if vibration appears in main motor, can increase the loading section nonconcentricity that is attached thereto, the increasing motor load, overload operation occurs, and then burn motor.All these will increase the failure-frequency of equipment, thereby increase maintenance cost, and increasing of the fault frequency can cause that again the outage rate of equipment increases, and then normal, the stable operation of influence production.The 2nd, excessive pressure under the situation that causes wearing and tearing such as base bearing, gear, usually can cause the main shaft serious wear, causes that gap of main reinforcement increases, and the concentricity of main shaft, the depth of parallelism can be affected, and the machining accuracy of lathe reduces greatly.The 3rd, regular high-voltage high-speed processing cutting, to the potential hidden danger of quality of processing quality band material of steel ball, defective such as often be prone to burn, chew, how these defective later process process meticulously again, also can't eliminate, and cause the increase of steel ball waste product, the folding rate of material reduces, and production cost increases.
The utility model content
The technical problems to be solved in the utility model provides a kind of 3M7990 ball grinder pressure real-time automatic intelligent monitoring protective device; can monitor the operating mode of ball grinder; prevent the ball grinder overload operation, influence the stability and the machining accuracy of lathe, avoid potential hidden danger of quality.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of 3M7990 ball grinder pressure real-time automatic intelligent monitoring protective device, its innovative point is: comprise a testing agency, this testing agency comprises three instrument transformers that insert main motor three-phase circuit respectively, is used for measuring in real time main motor three-phase current; A comprehensive computing processing sector; this comprehensive computing processing sector comprises control box; control chip; intelligent warning alarm; drive protecting actuator; control chip places in the control box; be connected with testing agency; send the action that signal carries out each actuator according to setup parameter after being used to receive main motor three-phase current signal; intelligent warning alarm; drive protecting actuator two actuators are connected with control chip; intelligent warning alarm is used to receive and carries out warning reminding after control chip sends alarm signal, and drive protecting actuator disconnects the Machine-Tool Control circuit after being used to receive the trip signal that control chip sends.
Further; be provided with delayer between described drive protecting actuator and the control chip; be used for trigger dropout action disconnection Machine-Tool Control circuit after control chip sends trip signal, and in delay time, receive the cancelling signal cancellation dropout action of control chip.
Advantage of the present utility model is: by testing agency ball grinder master current of electric is implemented to detect, this electric current and rated current contrast are handled accordingly, when the running current of motor surpass rated current 90% the time, the work of control chip control intelligent warning alarm reminds the staff to note.When running current reached the rated current of motor, control chip sent control signal, and the action of threading off disconnects the Machine-Tool Control circuit, and the protection lathe is avoided the further expansion of fault.
Be provided with delayer between drive protecting actuator and the control chip; when the ball grinder running current surpasses rated current; after control chip sends trip signal; the delayer timing; at this section in the period, if this section in the period equipment recover normally then not thread off action, as if the undesired action of then threading off; disconnect the Machine-Tool Control circuit, the lathe hard stop.Can avoid unnecessary shutdown and normal production has been impacted, guarantee the validity of equipment operation to greatest extent.
Description of drawings
Accompanying drawing is the utility model 3M7990 ball grinder pressure real-time automatic intelligent monitoring protective device structural representation.
Embodiment
As shown in drawings, the comprehensive computing processing sector that the utility model comprises testing agency and is connected with testing agency,
Testing agency comprises three instrument transformers 1 that insert ball grinder master motor three-phase circuit respectively, is used for measuring in real time main motor three-phase current.
Comprehensive computing processing sector comprises control box 2, control box 2 is built-in with the control chip 5 that is connected with testing agency, be used to receive main motor three-phase current signal, and send the corresponding actions that signal carries out each actuator according to the parameter of setting, on control box 2, be provided with viewing area 3 and setting district 4, be used to show and set the various parameters of control chip.
Between drive protecting actuator 6 and control chip 5, delayer is installed; can after control chip 5 sends trip signal, begin to carry out the delayed releasing action and disconnect the Machine-Tool Control circuit, and in delay time, receive the cancelling signal cancellation dropout action of control chip 5.
During work, at first the rated current with ball grinder master motor is arranged in the control chip 5 by viewing area 3 and setting district 4, instrument transformer 1 passes to control chip 5 in real time with detected main motor operating current signal, control chip 5 is according to the size of electric current and the load current value contrast of setting, if it surpasses 90%, control chip 5 sends alarm signal and gives intelligent warning alarm 7, reminds operating personnel to note the lathe operating condition of this moment.When the electric current of instrument transformer 1 detection reaches the rated current of motor; control chip 5 sends trip signal; delayer picks up counting; wouldn't trigger the dropout action of drive protecting actuator 6; if motor recovers normal operation in this time period, then cancel trip signal, do not recover normal yet if surpass the time-delay time limit; then drive protecting actuator 6 action of threading off disconnects the Machine-Tool Control circuit.
