Description
Technical field
The present invention relates to a kind of object of surveying and whether exist, can survey the sensor of the hole that gap between object or object self exist.
Background technology
At present, whether the known object of surveying exists, and the sensor that maybe can survey the object hole has vision sensor (or claiming the vision dragon), grating sensor, tact switch, optoelectronic switch etc.Vision sensor cost height, easily affected by environment; The grating sensor cost is higher, and is easily affected by environment, and needs supporting chromacoder; Tact switch has been subjected to power source (as cylinder) effect when touching object, send signal after, drive the stop motion immediately of the proal object of tact switch, otherwise tact switch is damaged easily, therefore, be not suitable for some place and select for use; Optoelectronic switch can detect the existence of object, maybe can detect hole, but luminophor and optical switch need be installed in diverse location, can only detect the through hole hole, and limited by the use location.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, long service life, conversion of signals to survey the sensor of object and hole easily.
To achieve these goals, technical scheme of the present invention is: the sensor of surveying object and hole, it is characterized in that it comprises contact 1, housing 2, spring 3, connecting rod 4, conversion block 5, inductor 7, housing 2 is provided with conversion block slippage chamber, inductor chamber, the inductor chamber communicates with conversion block slippage chamber, and contact 1 is fixedlyed connected with an end of conversion block 5 by connecting rod 4; Spring 3, conversion block 5 lay respectively in the conversion block slippage chamber, and the other end of conversion block 5 links to each other with an end of spring 3, and the other end of spring 3 links to each other with bonnet 8; Inductor 7 is positioned at the inductor chamber, and inductor 7 is linked to each other with housing 2 by inductor fixed head 6; Housing 2 is installed on the power source, and the axis direction of inductor 7 is vertical with the direction of motion of power source.
A fixedly connected connector 9 on the described housing 2, connector 9 links to each other with power source.
Described power source is cylinder, hydraulic cylinder, hand-held etc.
Described inductor fixed head 6 is provided with chute, and inductor 7 is positioned at chute.
The conversion block slippage chamber of described housing 2, inductor chamber are 2 groups, and contact 1, spring 3, connecting rod 4, conversion block 5, inductor 7 are corresponding 2 groups.
Described contact slabbing or needle-like, sheet thickness or needle-like diameter are 0.1mm.
Power source moving objects such as () cylinders drives sensor and travels forward, and when contact touched testee, contact stopped to travel forward; Under the inertial force effect or because topworks delays time, moving object meetings such as cylinder drive sensor housing travels forward, the certain distance that travels forward, and conversion block and inductor relative position change, and inductor sends switching signal.Cylinder moves forward, and spring 3 is compressed, relative motion between contact and power source, the housing, and at this moment, contact, connecting rod, conversion block and housing only are subjected to the spring force effect, and spring force and decrement are adjustable, and pressure can be adjusted by bonnet 8.Because length of spring compressed power is much smaller than cylinder or moving object power, it is bigger to be compressed distance, because of inductor vertical with direction of motion, and do not contact with contact, converter etc., therefore in whole detection process, be not subjected to the external force effect, thereby damage contact and inductor have been avoided, sensor long service life, and simple in structure, conversion of signals convenience.Adopt inductor 7 to be positioned at chute, inductor and conversion block relative position can be adjusted.When measuring hole, sensor contact can be done slabbing or needle-like, and sheet thickness or pin diameter can be little of 0.1mm.
The invention has the beneficial effects as follows: can be installed in the moving object such as cylinder, whether the test measured object exists or whether hole exists, and this hole is through hole no matter whether, all can be measured.Inductor does not stress, and contact is stressed little, the sensor long service life, and sensor construction is simple, and output quantity is a switching value, and conversion of signals is simple.
