Abstract
The utility model discloses a press-type sensor. A pair of blind pores is arranged in the middle of flexible part of the utility model. Bottoms of the two blind pores form a stalk plate. Two sets of resistance strain foil are arranged on the middle of the two sides of the stalk plate. The outer end port of the blind pore is provided with sponge layer. The cover board is arranged on the outer side of the sponge layer. The flexible part is connected with the upper connecting plate by screw thread. The working end screw thread of the flexible part is provided with a barrier block on the upper connecting plate which is fastened on the working end by countersunk head screw to prevent rotation of the flexible part in force carrying process. Under the flexible part is provided with stress end of sphere. Stress end of sphere is arranged in the lower connecting plate which is two semicircular structures, leaning against bearing plate on bottom of the lower connecting plate. The bearing plate is fastened on the lower connecting plate by six countersunk head screws. The lower connecting plate can rotate in 360 degrees around the body of the sensor. The installation is simply.
Description
Technical field
The utility model belongs to the resistance strain type sensor field, specifically relates to a kind of pressure type sensor.
Background technology
Traditional pressure type sensor, elastic body normally adopts column solid structure, when two force sides are under pressure, tension, compressive stress are difficult to evenly on the elastic body, elastomeric natural linear weak effect, the anti-bias load ability is not good enough yet, but also exist production technology more complicated, material therefor more, problem such as inconvenience is installed.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical matters, provide a kind of anti-bias load ability good, with material is less, easy for installation, natural linear is good, precision is high pressure type sensor.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of pressure type sensor, comprise gusset, second line of a couplet fishplate bar, between last gusset, second line of a couplet fishplate bar, connect elastic body is set, described elastic body middle part is symmetrical arranged a pair of blind hole, the bottom of two blind holes constitutes a web mutually, and two groups of resistance strain gages are posted in the centre of web both sides respectively; The external port place of described blind hole is provided with spongy layer, the arranged outside cover plate of spongy layer.
Described elastomeric upper end is the screw thread force side, and elastic body links into an integrated entity by screw thread force side and last gusset; Described elastomeric lower end is the sphere force side, the sphere force side is arranged in the cavity of second line of a couplet fishplate bar, and be resisted against on the loading plate of second line of a couplet fishplate bar bottom setting, loading plate is fixed on second line of a couplet fishplate bar bottom by six sunk screws, and connecting gusset down can rotate freely around sensor body 360 degree.
Described elastomeric screw thread force side is gone up gusset and is provided with block, and block is fixed on the screw thread force side by sunk screw, prevents that elastic body rotates in the loading process.
Also offer four through holes on the described elastomeric web.Described second line of a couplet fishplate bar adopts two semi-circular structure.
Advantage of the present utility model is: one, make the body of sensor have certain natural linear, the anti-bias load ability is better, and precision is higher; Two, be convenient to install, reduce the azimuthal error that is caused is installed, the unbalance loading phenomenon that produces when making carrying can not cause measuring accuracy to reduce; Three, move with sensor in the source of exerting oneself on, so that in applications such as traveling hoppers.
