Abstract
The utility model discloses a vibration meter which comprises a vibrating sensor arranged on a magnetic base and a cable connected with the vibrating sensor through a joint, wherein a shell is arranged outside the joint of the cable and the vibrating sensor; and hot melt adhesive is filled between the cable of the shell and the joint and the section of cable outside the joint. The vibration meter is used for detecting the vibration of an ageing object in vibration ageing process equipment. Compared with the traditional vibration meter, the vibration meter disclosed by the utility model can solve the problem of low reliability between the connecting cable and the vibrating sensor and has no fault and the working hour can be improved by 10 times compared with the prior art.
Description
Technical field
The utility model relates to the sensor application technical field, especially a kind of sensor that is used to detect vibration in the oscillating aging process equipment.
Background technology
Used oscillation pickup is made of magnetic support, vibration transducer and cable in the existing oscillating aging process equipment.Magnetic support is a pedestal of being made by permanent magnet material, be used to be adsorbed on ferromagnetism timeliness workpiece, vibration transducer is connected the top of magnetic support, and vibration transducer is connected with cable by cable connector, and the other end of cable is for connecting the link of oscillating aging measurement and control instrument.Because aging technique is when work, need to detect the resonant frequency on the timeliness workpiece, and need on the subresonance frequency, implement the oscillating aging operation to workpiece, under this process conditions, the existing oscillation pickup of bearing vibration detection is easy to cause the cable junction of connection to fracture, and causes equipment failure, and this phenomenon is not resolved for many years, have a strong impact on the reliability service of oscillating aging equipment, even therefore influence applying of oscillating aging this low energy consumption high-efficiency rate technology.
Summary of the invention
Problem to be solved in the utility model provides a kind of oscillation pickup that is used for oscillating aging technology, and this oscillation pickup can solve the low problem of connection reliability between its connection cable and the vibration transducer.
In order to address the above problem, the technical solution of the utility model is: this oscillation pickup, it includes vibration transducer that is contained on the magnetic support and the cable that is connected with this vibration transducer by joint, joint outside at described cable and described vibration transducer is provided with shell, is filled with hot melt adhesive between one section described cable outside this shell and described joint and this joint.
In the technical scheme of above-mentioned oscillation pickup, can also be more specifically: described magnetic support be the right cylinder of diameter greater than described vibration transducer side dimension, and described shell is the cylinder that is connected described magnetic support lateral surface; Described hot melt adhesive is coated on the lateral surface of whole described vibration transducer.Described cable is coated height H 〉=2 millimeter of section beyond the described joint by hot melt adhesive.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect: the oscillation pickup mean time between failures is brought up to 2500 hours by 250 hours of prior art.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing example:
It is 30 millimeters that this oscillation pickup shown in Figure 1 has a diameter, highly be 15 millimeters, the magnetic support of making by permanent magnetic material 1, being connected with one in the upper surface of magnetic support 1 is 24 millimeters by diameter, main part and an external thread diameter of highly being 24 millimeters are 10 millimeters, length is the vibration transducer 2 that 13 millimeters connector portions constitutes, electrode in vibration transducer 2 connector portions and cable 6 interior leads are connected, the external thread of vibration transducer 2 connector portions is fixedlyed connected with the overcoat of cable 6 by nut 5, nut 5 promptly is the jointing of alleged cable of the utility model and vibration transducer with the connector portions of vibration transducer 2, and the connector 7 of the other end of cable 6 is used for being connected with the oscillating aging measurement and control instrument at this oscillation pickup in use.The technical scheme of these parts is same as the prior art.In addition, being socketed with one section wall thickness in the outside of magnetic support 1 is 1 millimeter, the nylon tube 3 of tubular that highly is 56 millimeters is as shell, above the magnetic support 1, be filled with hot melt adhesive 4 between the lower end of nylon tube 3 and vibration transducer 2, nut 5 and cable 6, cable 6 is coated height H=2 millimeter of section by hot melt adhesive 4 more than 5 the attaching nut.
