Abstract
The utility model relates to a force sensor used for online testing the tension of linear objects, which is particularly applicable to online testing the tension of the moving yarn on a winding and reeling machinery or a spinning machine, during the producing in the textile industry. The utility model comprises an elastic sheet, one end of which is firmly fixed on a fixing flat plate, and the other end of which is a free end. One side of the free end of the elastic sheet is provided with a lead component, and the other side thereof is provided with a magnetic substance and a Hall Magnetic Sensor. The elastic sheet is generally in the structure of a rectangle with equal sections or in the structure of a trapezoid with same intensity; and an elastomer can adopt the single-head type or the double-head type. The utility model has the advantages that the composite effects combined by the elastic sheet and the Hall Magnetic Sensor can be used to convert the tension changes of a to-be-tested linear object into a corresponding displacement of the elastic sheet which is matched with the intensity of the magnetic field and which has a linear relationship with the electrical signals output by the Hall Magnetic Sensor, thereof, the tension changes of the to-be-tested linear object can be automatically tested on line.
Description
Technical field
The utility model relates to the force transducer of the online detection usefulness of thread-shaped body tension force, is particularly useful for the force transducer of the online detection usefulness of yarn tension in the motion on bobbin-winding machine in the caused by spinning industrial production or the spinning frame.
Background technology
In the commercial production, but the tension variation of the online detection The real time measure of thread-shaped body tension force thread-shaped body in the motion is in time adjusted processing parameter thus, guarantees the homogeneous of the motion tension force of thread-shaped body in the whole process of production, improves the quality of producing product.
Therefore, occurred various tension pick-ups at present both at home and abroad, mechanical type, condenser type, resistance-strain chip and photo-electric etc. have been arranged by the action principle classification.The force transformation flexible member that existing mechanical type tension pick-up adopts has following several again: uniform cross section cylindrical form, form of annular rings, uniform cross section sheet form, semi-girder form and torsion shaft version.
The complexity of above-mentioned various forms of tension pick-up and the application of force transformation flexible member, the tension range that is detected, accuracy of detection and fabrication and processing has nothing in common with each other, and length is respectively arranged.
Summary of the invention
The purpose of this utility model provides the online detection usefulness of a kind of thread-shaped body tension force, especially is suitable on bobbin-winding machine in the caused by spinning industrial production or the spinning frame force transducer of the online detection of yarn tension in the motion.
Of the present utility model being characterised in that comprises that an end is fastened on the fixed flat planar, the other end is free-ended flexure strip, the free-ended side of flexure strip is equipped with the wire guiding member that contacts with tested thread-shaped body, free-ended opposite side is fixed with magnetic, and magnetic is fixed with hall magnetic sensor in the formed magnetic field.Described flexure strip is a kind of force transformation flexible member, has adopted the form of uniform cross section thin plate described in the background technology and semi-girder combination, makes of alloy material, and shape has two kinds, and a kind of is uniform cross section rectangle flexure strip, and another kind is trapezoidal equal strength flexure strip; Described wire guiding member adopts various materials and the various forms of yarn guide of using in the weaving production; Described magnetic can adopt single head form or double end form.
The utility model has the advantages that in conjunction with the compound action of having utilized flexure strip and two kinds of sensor elements of hall magnetic sensor, the tension variation of tested thread-shaped body is transformed into the corresponding displacement of flexure strip, this displacement is corresponding with change of magnetic field strength, and linear with the electric signal of hall magnetic sensor output, thus can be accurately, in real time tested thread-shaped body tension variation is carried out online automatic detection.
Description of drawings
Accompanying drawing 1 is a basic structure synoptic diagram of the present utility model, and the magnetic that is adopted is the double end form; Fig. 2 is a uniform cross section rectangle flexure strip synoptic diagram; Fig. 3 is the trapezoidal flexure strip synoptic diagram of equal strength; One-piece construction figure when Fig. 4 is positioned at thread-shaped body the same side for wire guiding member with the turnover metallic channel, the magnetic that is adopted is the single head form; One-piece construction synoptic diagram when Fig. 5 is positioned at the thread-shaped body both sides for wire guiding member with the turnover metallic channel; Fig. 6 is located on the structural representation of flexure strip free end end for wire guiding member and magnetic; Fig. 7 is positioned at apart from the structural representation of free end end certain distance for wire guiding member is positioned at flexure strip free end end magnetic.Among the figure:
The 1-flexure strip; The 2-fixed flat planar; The 3-wire guiding member; The 4-magnetic; The 5-hall magnetic sensor; The 6-fixed flat planar; 7-turnover seal wire groove; The tested thread-shaped body of 8-; The 9-square box.
Embodiment
As Fig. 4, shown in Figure 5, one-piece construction of the present utility model is placed in the square box 9, and the both sides of square box 9 are provided with imports and exports seal wire groove 7, and the thread-shaped body 8 in the motion can swing at the position of seal wire groove 7.
Flexure strip 1 is a sheet metal, often adopts alloy material.When selecting the flexure strip 1 of different elastic modulus, different in width, different length or different-thickness for use, can change dynamometry scope, resolution sizes and, reach measurement requirement thus the control of the deflection of flexure strip 1.
In the measuring process, under the effect of power P, flexure strip 1 displacement, drive magnetic 4 simultaneously corresponding displacement also takes place, cause changes of magnetic field thus, hall magnetic sensor 5 is measured the tension variation value of tested thread-shaped body 8 in real time with the linear form output that changes of electric signal.
The magnetic 4 that is adopted can be single head or double end, changes the fixed position of magnetic 4 on flexure strip 1, or when changing intensity, spacing, the size of magnetic 4, also all can adjust the size of dynamometry scope or resolution.
