Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of New type of S type of the utility model load cell comprises sensor main body 1, sensor outer housing 2 and signal wire 11, and sensor main body 1 outside is equipped with sensor outer housing 2, is connected with signal wire on the sensor outer housing 2, as shown in Figure 1.
Wherein, sensor main body 1 is long 80mm, wide 67mm, and the rectangular parallelepiped of high 28mm adopts the 30CrMnSiA material, forms through quenching, and the back HRC that quenches should reach 42, makes sensor main body 1 have elasticity more thus.Top, long limit, right side at sensor main body 1 has transverse concave groove A3, and bottom, long limit, left side has horizontal groove B4, forms " S " type structure thus, and as shown in Figure 2, this " S " type structure is that time processing forms.On the sensor main body 1 between groove A3 and the groove B4, have two through hole A5 and through hole B6 that wait size that are interconnected along the short transverse of sensor main body 1, through hole A5 is communicated with the vertical axis of sensor main body 1 is tangent and symmetrical with through hole B6.The top cambered surface of through hole A5 and through hole B6 and the radius-of-curvature of bottom cambered surface are 7.5mm, and the vertical range l between through hole A5 and the vertical axis of through hole B6 is 7.5mm.All posting foil gauge 7 on cambered surface and the lower camber side on through hole A5 and the through hole B6.
Have upper screwed hole 8 and following threaded hole 9 at sensor main body 1 upper surface and lower surface, and upper screwed hole 8 communicates with groove A3, following threaded hole 9 communicates with groove B4.Upper screwed hole 8 is used for connecting the parts (as: handle) that make sensor stressed, and following threaded hole 9 can be installed the parts (as: hook) that are used for being connected and fixed testee.
Having signal wire connecting hole 10 on the long limit, the left side of sensor main body 1 or on the long limit, right side, signal wire connecting hole 10 is communicated with through hole A5, through hole B6.Signal wire connecting hole 10 is used for installing signal wire 11, and signal wire 11 1 ends pass signal wire connecting hole 10 and are connected with foil gauge among through hole A5, the through hole B6, and by fixing with being threaded of signal wire connecting hole 10; The other end of signal wire 11 is used for being connected with outside weighing instrument.When check weighing, the deformation by foil gauge 7 embodies stressed size.
Because the check weighing scene has certain pollution sometimes, therefore on through hole A5 and through hole B6 inwall, scribble 704 silicon rubber, be used for protecting through hole A5 and the foil gauge 7 of through hole B6 inside and the signal wire 11 that links to each other with foil gauge 7.Because therefore 704 silicon rubber good springiness can not produce friction force to foil gauge 7, thereby make measurement more accurate.Have shell mounting hole 12 in sensor main body 1 lower end, install sensor outer housing 2 additional at through hole A5 and through hole B6 place by shell mounting hole 12, thus better protection the inner structure of through hole A5 and through hole B6.Can prolong the serviceable life of sensor thus.
The S type sensor of making by above-mentioned dimensional structure is with respect to existing S type sensor, can effectively improve the measurement range of sensor, make it reach 100kg～1000kg, and the existing S type sensor of the intensity of the utility model sensor and ratio of rigidity is big, therefore overload-resistant ability is strong, overload can reach 150%～170%, and sensor can be because of stressed not excessive and produce distortion after overload, thereby scraps.
