Summary of the invention
The utility model has mainly solved: the weight induction part of general weight sensor and holder part fixation and being inconvenient to of causing overhauls or weight induction is partly changed provide replacing of a kind of easy access or weight sensor and the high weight sensor of measuring accuracy.
The technical solution adopted in the utility model is: a kind of weight sensor, comprise base plate, the side has the elastic body of water joint, compression leg, top board and adjustment screw rod, base plate is rectangular, the middle part of the upper surface of base plate has the mounting hole that matches with elastic body, elastic body is cylindrical, the elastic body lower end is embedded in the mounting hole of base plate, compression leg is cylindrical and between elastic body and top board, have several on base plate and the top board and be used to install the mounting hole of adjusting screw rod, the screw rod of adjustment screw rod passes the mounting hole riveted joint of the mounting hole and the base plate of top board, has some pilot holes on base plate and the top board.Elastic body is used for the weight of sense object, and elastic body is the weight induction part of weight sensor, and embeds in the mounting hole of base plate easy access or replacing.
The middle part of described elastomeric upper surface extends upward a cylinder plush copper, and cylinder plush copper and elastic body are coaxial.Described compression leg lower surface has cylindrical groove, cylindrical groove end face cambered surface spherical in shape, and cylindrical groove and elastomeric cylinder plush copper shape match, and cylindrical groove is coaxial with compression leg.Cylinder plush copper and cylindrical groove cooperate the position that is used to locate between compression leg and the elastic body
The upper surface of described compression leg is provided with a concentric cylinder, the upper surface of the described cylinder cambered surface spherical in shape that raises up, and the upper surface of the cylindrical groove of compression leg lower end convexes to form spherical arc downwards.The top of compression leg and the stress surface of base plate are sphere, have so just formed the bearing structure of two bulbs, and loaded area increases, and has improved weighing precision and anti-bias load ability.
Described top board lower surface middle part has the cylindrical groove that matches with the compression leg upper end, as preferably, and groove side and top board lower surface angled transition.Cylindrical groove is used to locate compression leg.
The mounting hole of described top board is two, and the axis of two mounting holes is positioned at elastomeric both sides, and the axis of elastomeric axis and two mounting holes in one plane, and the lower end of mounting hole cooperates with the sloping portion at the top of adjusting screw rod.The mounting hole of described base plate is two threaded holes, and two threaded holes are corresponding with two mounting holes of top board respectively, and threaded hole and adjustment screw flight screw rod interference fit.The mounting hole that the adjustment screw rod passes top board is riveted in the threaded hole of base plate, and base plate and top board are coupled together.
As preferably, the end angle of elastic body and compression leg is fillet, avoids most advanced and sophisticated collision.
The beneficial effect that the utility model is obtained is: the top and the base plate of pressure head are spherical arc, and loaded area is big, have improved weighing precision and anti-bias load ability; Elastic body embeds base plate easy access and replacing.
