Detailed description of the invention
Below in conjunction with embodiment, the utility model will be further described, but does not constitute any restriction of the present utility model, and the amendment of anyone limited number of time made at this utility model right, still in right of the present utility model.
Specific embodiment of the utility model is such that with reference to shown in Fig. 1-Fig. 4; a kind of transmission main shaft exception vibration protector; including fixed support 1 and the driving control system of transmission main shaft 7; fixed support 1 is provided with the sensor 3 of sensing transmission main shaft 7 vibration amplitude, and the signal output part of sensor 3 connects driving control system by wire.
In the present embodiment, fixed support 1 is provided with the spindle hole 2 that transmission main shaft 7 passes, and sensor 3 is multiple, multiple sensors 3 are distributed in around above-mentioned spindle hole 2, fixed support 1 simple and practical, can be suitable for and polytype transmission main shaft 7, be widely used.Sensor 3 can use microswitch, distance element sensor etc., can reach same technique effect.
In the present embodiment, sensor 3 is 3-6, and sensor 3 uses microswitch, microswitch to include stationary contact 301 and movable contact spring 302, is provided with fine motion pressure head 303 on movable contact spring 302；Fine motion pressure head 303 is roller type pressure head, and fine motion pressure head 303 is projecting inward to spindle hole 2.Microswitch is normally closed switch, and microswitch cathode circuit connects coil power 5, and microswitch cathode traces connects driving and controls jerk relay 4；Multiple microswitch are connected in series.As long as fine motion pressure head 303 is collided or extrudes, it is possible to trigger microswitch and disconnect, relay 4 power-off, so that transmission main shaft 7 shuts down, reach the effect of automatic shutdown protection, effectively prevent transmission main shaft 7 and adnexa thereof to be damaged.
In the present embodiment, fine motion pressure head 303 quantity is 5, it is evenly distributed on around spindle hole 2, multiple microswitch can be in the shock conditions of multiple angles detection transmission main shaft 7, fine motion pressure head 303 by transmission main shaft 7 collision or extruding under, the movable contact spring 302 of microswitch is extruded, makes movable contact spring 302 separate with the stationary contact 302 of microswitch.Fine motion pressure head 303 can shake automatically according to the exception of transmission main shaft 7 makes a response delicately, and accurately, response speed is fast in detection.
In the present embodiment, fine motion pressure head 303 is roller type pressure head, and one end of fine motion pressure head 303 is connected with the movable contact spring 302 of microswitch, and the other end of fine motion pressure head 303 is projecting inward to spindle hole 2.Fine motion pressure head 303 is roller structure to one end that spindle hole 2 is projecting inward; when contacting with transmission main shaft 7; the roller of fine motion pressure head 303 can be at the surface scrolls of transmission main shaft 7; prevent fine motion pressure head 303 and transmission main shaft 7 from carrying out dry friction and causing damage; the most effective anti-locking apparatus crashes with transmission main shaft 7; enhancing the life-span of device, also protect main shaft, structure design is simple and practical, safe and reliable.
In the specific implementation, as Figure 1-Figure 4, first five microswitch being uniformly fixed to the edge of spindle hole 2, use wire five microswitch to be together in series, at this moment the movable contact spring 302 of microswitch is in close contact with stationary contact 301；Again fixed support 1 is fixed on lathe, the transmission main shaft 7 making lathe passes the spindle hole 2 fixed support 1 from center, amplitude of vibration maximum according to the normal transmission of transmission main shaft 7, adjust the position of microswitch and fine motion pressure head 303 and the mounting distance of transmission main shaft 7, make the roller type fine motion pressure head 303 of microswitch be positioned at the peak of transmission main shaft 7 normal vibration.The extruding fine motion pressure head 303 when the abnormal vibrations of transmission main shaft 7 reach restriction site, the movable contact spring 302 triggering microswitch separates with stationary contact 301, controls jerk relay 4 power-off, thus automatic emergency stops driving equipment 6, in time protection transmission main shaft 7 and adnexa thereof.
Below it is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement, these are all without affecting effect and the practical applicability that this utility model is implemented.
