Abstract
The utility model discloses a sensor lifting device which comprises a vibration measurement head, a spring, a sleeve and a sensor. The sensor is arranged in the sleeve. The vibration measurement head passes through one end of the sleeve and then is connected with the sensor. The spring drives the sensor to abut against the end part of the sleeve. The sensor lifting device further comprises a cylinder. A piston rod of the cylinder is connected with the vibration measurement head. The axis of the piston rod of the cylinder is parallel to the axis of the vibration measurement head. After a bearing is measured, the cylinder takes the piston rod back. When the piston rod is taken back, the vibration measurement head is driven to be lifted up and leaves the outer ring of the measured bearing. When the measured bearing is removed from a measurement mandrel, friction and rigid collision between the vibration measurement head and the outer ring of the bearing are prevented. The vibration measurement head is prevented from being worn or damaged, and thus the accuracy of the measurement data and the reliability of the instrument are not affected. Measurement traces are prevented from being left on the outer ring of the bearing.
Description
Technical field
The utility model relates to bearing detection technique field, relates in particular to a kind of sensor lifting gear.
Background technology
Bearing is one of fundamental parts the most key in the rotating machinery, and the quality of bearing is directly connected to the serviceability of machine-tool.In order to guarantee bearing quality, must carry out strict detection to it.In the bearing quality test item, bearing vibration value is to weigh the most general, the most important index of bearing dynamic property at present.Bearing quality and its vibration values are inversely proportional to.
The acceleration type bearing vibration measuring instrument is a kind of instrumentation of measuring bearing vibration value, is widely used in Chinese bearing industry.The way of contact of the same measurand of the acceleration transducer of acceleration type bearing vibration measuring instrument (vibration of bearing outer ring) is a kind of special probe-type mechanism, and this probe-type mechanism is called the sensor measuring system of acceleration type bearing vibration measuring instrument.
When measuring bear vibration, need be pressed into measured bearing under the vibration measuring head along axle, the vibration measuring head directly contacts with bearing outer ring, and allows both maintain certain contact force by compression spring.Axially loading head is carried in bearing outer ring, and it is not rotated, and bearing inner race is pressed the certain speed rotation under the drive of mandrel.Bearing vibration passes to acceleration transducer by the vibration measuring head.Therefore, measure bear vibration, both needed measured bearing is pressed under the vibration measuring head, need again the bearing after measuring is pulled out under the vibration measuring head.Because the frequent loading and unloading of bearing on mandrel, the vibration measuring head can be worn, even is broken, thereby influences the accuracy of measurement data and the reliability of instrument.On the other hand, because the existence of contact force can stay so-called measurement vestige on bearing outer ring--wedge angle " Λ " influences the outward appearance of bearing.
Summary of the invention
The utility model provides a kind of sensor lifting gear at deficiency of the prior art, can avoid vibration measuring head and bearing outer ring friction, hard collision when bearing need be pulled out.
For solving the problems of the technologies described above, the utility model is solved by following technical proposals: the sensor lifting gear, comprise vibration measuring head, spring, sleeve and sensor, described sensor is arranged in the described sleeve, described vibration measuring head links to each other with described sensor after passing described sleeve one end, the end that described spring promotes described sensor and described sleeve against, also comprise a cylinder, the piston rod of described cylinder links to each other with described vibration measuring head, the parallel axes of the axis of described cylinder piston rod and described vibration measuring head.After bearing measuring finishes, cylinder is regained piston rod, in the process that piston rod is regained, driving the vibration measuring head upwards carries, leave the outer ring of measured bearing, at this moment when measuring mandrel and take off, friction and hard collision can not take place with bearing outer ring to measured bearing in the vibration measuring head again, avoid vibration measuring head wearing and tearing or break, thereby influence the accuracy of measurement data and the reliability of instrument.On the other hand, also can avoid on bearing outer ring, staying so-called measurement vestige.
In the technique scheme, preferably, described sleeve comprises the pipe of a both ends open, one end of described pipe is provided with and the contacted clamping sleeve of described spring one end, the other end of described spring contacts with described sensor, the other end of described pipe is provided with guide, has one first through hole on the described guide, and described vibration measuring head matches with described first through hole.
In the technique scheme, preferred, described piston rod links to each other with described vibration measuring head by first plate.
In the technique scheme, preferably, also comprise fixed mount and knob, described knob has double-screw bolt, and described fixed mount is arranged on the head, second through hole that described fixed mount is provided with second plate, mounting hole and communicates with described mounting hole, be provided with jacking block in described second through hole, described sleeve passes described mounting hole, and described second plate is provided with screw, described double-screw bolt matches with described screw, and the end of described double-screw bolt holds out against described jacking block.
The beneficial effects of the utility model are: after bearing measuring finishes, cylinder is regained piston rod, in the process that piston rod is regained, driving the vibration measuring head upwards carries, leave the outer ring of measured bearing, at this moment when measuring mandrel and take off, friction and hard collision can not take place with bearing outer ring to measured bearing in the vibration measuring head again, avoid vibration measuring head wearing and tearing or break, thereby influence the accuracy of measurement data and the reliability of instrument.On the other hand, also can avoid on bearing outer ring, staying so-called measurement vestige.
