Description

The bearing detector

Technical field

The utility model is relevant for a kind of detector, refers in particular to a kind ofly can go out axle center off normal and the convenient bearing detector of replacing by real-time inspection.

Background technology

At present, general factory transportation gas or liquid, often need finish by machine tool (for example pump), see also Fig. 1, Fig. 1 is known pressure detector sectional view, early stage machine tool is because of installing pressure detector 1, but pressure detector 1 does not have acousto-optic or light prompt, need the operator to be careful with breathless interest, in use the operator has refreshing all of a sudden slightly or leaves, this moment, gas or leaked liquid were not found with regard to being left in the basket easily, and gas that leaks outside or liquid are if poisonous gas or liquid or when having corrosive gas or liquid, consequence is with hardly imaginable.

The general purpose tool machine is in running; can be accompanied by running and produce vibrations; and the vibrations of axle can cause the lifting of fraction defective; so how to avoid the axle vibrations; reduce loss with finding a vibrations as early as possible; it is exactly an important problem; automatic thrust-balancing system usually can be set in machine tool; feasible axle can maintain correct position running; but this also can't prevent the generation of axle vibrations fully; therefore how to allow the operator notice in the shortest time that the axle vibrations take place and processing in real time, the order loss drops to minimum, seems very important.

Traditional way is to install pressure detector 1 additional at machine tool, as shown in Figure 1, the below of this pressure detector 1 is provided with upper cover plate 11, and clip is in the opening of pressure detector 1 below, pressure detector 1 other part engages the back and uses the welding weldering dead, make pressure detector 1 inside form confined space, and in this confined space perfusion inert gas 2, make pressure detector external and internal pressure difference, utilize the running of pressure differential detection axle, in case the axle center has the normal orbit of departing from will impact upper cover plate 11 two ends, cause the inert gas 2 of pressure detector 1 inside to leak, pressure detector 1 pressure decline this moment also is reflected on the tensimeter, when seeing this situation, the operator will stop the machine tool running, and replacing pressure detector 1 and inner body, in order to avoid result in greater loss, but pressure detector 1 can not be reused, after in case inner inert gas 2 leaks, just whole of palpus is changed, quite not environmental protection, waste material and pressure detector 1 cost an arm and a leg, and also are cost burdens for the insider.

Just above-mentioned said, install pressure detector 1 additional at machine tool, though can be sensitive sense above-mentioned said shortcoming, but in the process, the operator need notice every now and then that still the tensimeter on the pressure detector 1 changes, and is careless slightly, when discovered, gas or liquid leak outside, so very undesirable.

The utility model content

In view of this, it is a kind of when gas or liquid leakage that the purpose of this utility model is to provide, and can send tweeting sound or caution light, makes the operator find in real time and bearing detector that can local replacement part.
