Description
Technical field
The utility model relates to a kind of sensor, relates in particular to a kind of rod-type displacement transducer.
Background technology
The rolling-mill housing up and down purpose of intermediate calender rolls string roller displacement measurement is to detect and control the physical location of the upper and lower intermediate calender rolls of frame.By technological transformation, the mode that former employing rack-and-pinion transmission is driven the absolute encoder counting transform the mode that adopts the rod-type displacement transducer to cooperate magnet ring to count as at present.This rod-type displacement transducer generally comprises the electronics storehouse, the installation portion that links to each other with the electronics storehouse, the sounding rod that links to each other with installation portion and be installed in slip magnet ring on the sounding rod.From actual operating position, the measuring accuracy of rod-type displacement transducer is higher, satisfies the requirement of unit.But this rod-type displacement transducer very easily is damaged, and by damaged condition is analyzed, main cause has:
1, the mounting bracket of former rod-type displacement transducer is open, only as the fixing of sensor and usefulness, outside the electronics storehouse of sensor, sounding rod, slip magnet ring all are exposed to.Be subjected to the impact of the rugged surroundings such as steam, greasy dirt of frame emulsion, electronics storehouse internal poles moisture-sensitive causes the electronics storehouse to be damaged.
2, the electronics storehouse of sensor, sounding rod and slip magnet ring do not adopt any safeguard measure; when overhaul of the equipments or fault handling; very easily be subjected to extraneous factor (for example: the people for trample, instrument bump etc.) sounding rod flexural deformation occurs, the situation such as the electronics storehouse is impaired, the slip magnet ring breaks, directly cause sensor to damage or the measurement data mistake.
3, the sounding rod of sensor end is fixing not tightly, very easily loosening.The slip magnet ring is when sounding rod slides, and sounding rod shakes, and causes measuring error larger.
The utility model content
The technical matters that the utility model solves provides a kind of non-damageable rod-type displacement transducer.
The technical scheme that its technical matters that solves the utility model adopts is: the rod-type displacement transducer, comprise the electronics storehouse, the transmission line and the installation portion that link to each other with the electronics storehouse, the sounding rod that links to each other with installation portion and be installed in slip magnet ring on the sounding rod, also comprise support, described support comprises the cavity of sealing, described electronics position in storehouse is in cavity, described installation portion is connected with nut thread on the front side wall that is arranged on cavity, the through wires hole that arranges on the rear wall of described transmission line by cavity passes, described support also comprises the cell body that is used for taking up sounding rod that links to each other with cavity, described slip magnet ring is positioned at cell body, the end of cell body is provided with limiting plate, has spacing hole on the limiting plate, and the end of sounding rod passes the outside to limiting plate by spacing hole.
Because the electronics storehouse is subject to the protection of cavity, sounding rod and slip magnet ring are subject to the protection of cell body, so that the sensor in use, are difficult for being damaged because of external environment influence.Simultaneously, the end of sounding rod is subject to the limited support of limiting plate, has avoided sounding rod to shake in use.
Further be: the sidewall of cell body is provided with the installation through hole.
The beneficial effects of the utility model are: not fragile, long service life is convenient to maintenance and installation.
Description of drawings
Fig. 1 is the schematic diagram of rod-type displacement transducer of the present utility model;
Be labeled as among the figure: electronics storehouse 1, cavity 2, installation portion 3 is installed through hole 4, limiting plate 5, sounding rod 6, slip magnet ring 7, cell body 8, spacing hole 9, transmission line 10.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, rod-type displacement transducer of the present utility model, comprise electronics storehouse 1, the transmission line 10 that links to each other with electronics storehouse 1 and installation portion 3, the sounding rod 6 that links to each other with installation portion 3 and be installed in slip magnet ring 7 on the sounding rod, also comprise support, this support can be made by the rectangle square steel, described support comprises the cavity 2 of sealing, described electronics storehouse 1 is positioned at cavity, described installation portion 3 is connected with nut thread on the front side wall that is arranged on cavity, and the through wires hole that arranges on the rear wall of described transmission line 10 by cavity passes, and described support also comprises the cell body 8 that is used for taking up sounding rod 6 that links to each other with cavity 2, described slip magnet ring 7 is positioned at cell body, the end of cell body 8 is provided with limiting plate 5, has spacing hole 9 on the limiting plate, and the end of sounding rod 6 is passed to the outside of limiting plate 5 by spacing hole.When arranging, can be first the rear wall of cavity is separated with other parts and open a through wires hole at rear wall, then at front side wall boring and mounting nuts, the sounding rod of the sensor hole by front side wall is passed to cell body, and installation portion and nut thread are connected and fixed, sensor is fixed on the support.Then the rear wall welding is made the sealing of electronics storehouse, and transmission line is passed by the through wires hole on the rear wall.In the said structure, because electronics storehouse 1 is subject to the protection of cavity 2, effectively protect electronics storehouse 1 not to be subjected to emulsion, greasy dirt and external damage, sounding rod 6 and slip magnet ring 7 are subject to the protection of cell body 8, are difficult for damaging because of external force when inspection and maintenance.Can make like this this sensor integral body not be vulnerable to external environment influence, therefore not fragile.Simultaneously, because the end of sounding rod is subject to the position-limiting action of limiting plate 5, so that sounding rod is difficult for rocking when using, guaranteed the accuracy of measuring.
On the basis of the above, fix for the ease of the installation of sensor, can be provided with at the sidewall of above-mentioned cell body 8 through hole 4 is installed.As shown in Figure 1, can be convenient to like this installation of sensors is fixed on the corresponding reference field.
During actual the use, for improving the intermediate calender rolls positional accuracy measurement, should be noted 2 points during installation of sensors: the one, support should move the cylinder keeping parallelism with axle as far as possible; The 2nd, unsuitable long with the brace of slip magnet ring.
