Abstract
The utility model relates to a grinding wheel sharpening control system for a shaving machine. The grinding wheel sharpening control system comprises a hydraulic system, an oil needle, a first travel switch, a PLC (programmable logic controller) and a bi-directional motor, wherein the hydraulic system is connected with the oil needle, and an output end of the first travel switch is connected with an input end of the PLC; and an output end of the PLC is connected with an input end of the PLC. The grinding wheel sharpening control system also comprises a second travel switch and a travel contact, wherein an output end of the second travel switch is connected with the input end of the PLC, and the travel contact is arranged on a travel track of a shaving machine body. The situation that the oil needle is pressed by oil pressure to be controlled is converted into the situation that a grinding machine sharpening system is touched by mechanical travel to be controlled, so that the system stagnation problem caused by failure of the oil needle is avoided. The system has the advantages of simple structure, low cost and strong controllability.
Description
Technical field
The utility model relates to a kind of emery wheel sharpening control system, relates in particular to a kind of shaving machine emery wheel sharpening control system.
Background technology
The Italian shaving machine emery wheel of at present domestic most use import sharpening control system, as shown in Figure 1, this system comprises hydraulic system (not shown), spindle 1, the first travel switch 4, PLC 6, either-rotation motor 7.This Italy's shaving machine emery wheel sharpening control system is by oil-in 2 oil-feeds, oil pressure promotes spindle 1 and stretches out, the stroke contact 3 of touching travel switch 4, make travel switch 4 transmit a signal to PLC 6, PLC 6 control either-rotation motors 7 carry out backward rotation, either-rotation motor 7 drives emery wheel and rotates for oil body 11, reaches and so forth the sharpening effect.In this shaving machine emery wheel sharpening control system, because spindle is meticulous, stops up easily, rupture in the use procedure.In case fracture damage, domestic do not have same model spindle 1 to substitute, want repair to need from external import, and the required overlong time of import, expensive, and machine is idle, even have equally above-mentioned hidden danger after changing spindle.
The utility model content
The purpose of this utility model provides a kind of shaving machine emery wheel sharpening control system, can reduce the oil supply system of shaving machine own because the sharpening control system paralysis that inner spindle fault is brought makes shaving machine emery wheel sharpening control system steady operation.
The utility model adopts following technical proposals: a kind of shaving machine emery wheel sharpening control system, comprise hydraulic system, spindle, the first travel switch, PLC and either-rotation motor, hydraulic system connects spindle, the output of the first travel switch connects the input of PLC, the output of PLC connects the input of either-rotation motor, also comprise the second travel switch and stroke contact, the output of the second travel switch connects the input of PLC, and the stroke contact is installed on the shaving body stroke track.
The utility model is by outside stroke contact and the second travel switch of increasing.The second travel switch is controlled in touching stroke contact when emery wheel moves back and forth, and makes the second travel switch transmit a signal to PLC, and PLC control either-rotation motor moves back and forth, and has avoided the spindle fault to cause the system breakdown problem.And native system is simple in structure, with low cost, controllability is strong.
Description of drawings
The structural representation of the emery wheel sharpening control system of the existing shaving machine of Fig. 1;
Fig. 2 is structural representation after the new improvement of this practicality.
The specific embodiment
As shown in Figure 2, the utility model comprises hydraulic system (not shown), spindle 1, the first travel switch 4, the second travel switch 5, PLC 6, either-rotation motor 7 and stroke contact 8, hydraulic system connects spindle 1, the output of the first travel switch 4 connects the input of PLC 6, the output of PLC 6 connects the input of either-rotation motor 7, the second travel switch 5 is installed in emery wheel on the oil body 11, the output of the second travel switch 5 connects the input of PLC 6, and stroke contact 8 is installed in above the stroke track 9.
During work, normal operation is mode as described in the background art just, the normal operation of shaving machine sharpening control system, if there is fault, result in blockage or when rupturing such as spindle 1, stroke contact 10 supplies the rotation of oil body 11 to touch stroke contact 8 with emery wheel, make the second travel switch 5 transmit a signal to PLC 6, PLC 6 outputs a control signal to either-rotation motor 7 after receiving signal, make either-rotation motor 7 carry out backward rotation after postponing several seconds seconds, stroke contact 10 supplies the rotation of oil body 11 again to touch stroke contact 8 with emery wheel during backward rotation, make the second travel switch 5 transmit a signal to PLC 6, PLC 6 outputs a control signal to either-rotation motor 7 after receiving signal, postpones again to make after several seconds either-rotation motor 7 to carry out forward rotation, emery wheel makes the sharpening control system continue normal operation with this reciprocating rotation.Stroke contact in the utility model is iron nail.Because the stroke contact act as simple touching stroke contact 10, so can provide the object of touching to use, do not giving an example one by one at this.
Claims (1)
1. shaving machine emery wheel sharpening control system, comprise hydraulic system, spindle, the first travel switch, PLC and either-rotation motor, hydraulic system connects spindle, the output of the first travel switch connects the input of PLC, the output of PLC connects the input of either-rotation motor, it is characterized in that: also comprise the second travel switch and stroke contact, the output of described the second travel switch connects the input of PLC, and the stroke contact is installed on the shaving body stroke track.
