Description
Technical Field
The utility model belongs to the technical field of the sensor, concretely relates to flange formula totally enclosed tension sensor.
Background
At present, strain type principles are mainly used by tension sensors at home and abroad, the tension sensors are used for controlling the production quality during the production of steel wire ropes, the tension of the steel wire ropes needs to be measured through the tension sensors, the tension sensors at home and abroad can only reach IP66 grades at present, but the workshop of the steel wire rope production is often high-temperature high-humidity and greasy dirt and dust, the IP66 grade is not applicable, if the steel wire ropes are welded with a shell through a simple elastomer, although the sealing effect can be achieved, the measurement precision of the sensors can be greatly influenced due to the fact that the sensors are based on the strain type principles, and the sealing tension sensors capable of solving the problems are urgently needed.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model provides a flange formula totally enclosed tension sensor can realize the sensor that is suitable for under high temperature and high humidity, greasy dirt dust environment.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a flange type full-sealed tension sensor comprises a connecting shaft and an elastic element arranged at one end of the connecting shaft, wherein a flange plate used for fixing the device is arranged at one end, away from the connecting shaft, of the elastic element, a cable is arranged in the middle of the flange plate, and the cable is electrically connected with the elastic element through a circuit board;
the elastic element is provided with a strain gauge, and the corrugated pipe is sleeved outside the elastic element.
Preferably, the middle part of the elastic element is a cuboid, two ends of the elastic element are cylinders, the strain gauge is installed on the side wall of the cuboid with smaller area, and the through hole is formed in the side wall of the cuboid with larger area.
Preferably, the bellows is laser welded to the cylindrical body at both ends of the elastic member.
Preferably, the elastic element and the corrugated pipe are made of stainless steel with the same elastic modulus.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the utility model has the advantages that the bellows is laser welded at the two ends of the elastic element, and the material of the bellows is designed into the stainless steel material with the same elastic modulus as the elastic element, so that the bellows can play a role in sealing and the measuring precision of the sensor is not influenced;
(2) the utility model discloses an at elastic element's one end mounting flange dish, the cable that will be connected with elastic element passes from the center of ring flange, has realized that this device has installation, measurement convenience, characteristics that occupation space is little.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 2, a flange-type fully-sealed tension sensor comprises a connecting shaft 5 and an elastic element 4 mounted at one end of the connecting shaft 5, wherein a circuit board is mounted on the elastic element 4, a flange 2 for fixing the device is mounted at one end of the elastic element 4, which is far away from the connecting shaft 5, a plurality of flange holes 21 are circumferentially arranged on the flange 2 for fixing the device, a cable 1 is mounted in the middle of the flange 2, the cable 1 is electrically connected with the elastic element 4 through the circuit board, and the other end of the cable 1 is connected with an external receiver;
the middle part of the elastic element 4 is a cuboid, two ends of the elastic element are cylinders, a strain gauge 42 is installed on the side wall of the cuboid with a smaller area, a through hole 41 is formed in the side wall of the cuboid with a larger area, the through hole 41 is a force sensitive area and is easy to be strained, the strain gauge 42 is arranged on the thin wall of the through hole 41, when the elastic element 4 is under tension, the force sensitive area of the elastic element 4 is strained, the strain gauge 42 attached to the force sensitive area is also strained, because the strain makes the resistance of the strain gauge 42 slightly change, the slight resistance change generates a pressure difference, the pressure difference is the signal of the sensor, the cable 1 can transmit the signal to an external receiver, the corrugated pipe 3 is sleeved outside the elastic element 4, the corrugated pipe 3 has a contraction function after being stressed, the measurement precision is not influenced, and the service life is longer, bellows 3 laser welding is on the cylinder at elastic element 4 both ends, and the cylinder conveniently carries out weldment work to bellows 3, elastic element 4 is the same elastic modulus's stainless steel with bellows 3, does not influence measurement accuracy.
During the use, it is fixed with this device through ring flange 2, the one end of the wire rope of awaiting measuring is connected on connecting axle 5, after tensile wire rope, elastic component 4 receives the strain, when elastic component 4 receives tensile, it also receives the strain to attach in the foil gage 42 in elastic component 4 sensitive area, the resistance of foil gage 42 has taken place small change, small resistance change has produced a pressure differential, foil gage 42 passes through cable 1 with signal output, bellows 3 can play sealed effect, can work in the environment of high temperature and high humidity, greasy dirt dust.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
