The utility model aims to solve a technical problem of low detection precision of a prior shaft-pin-type sensor and provides the shaft-pin-type sensor. The shaft-pin-type sensor has a simple structure and high detection precision and can be installed conveniently. The shaft-pin-type sensor includes a shaft pin. The shaft pin is an elastic piece integrally. A plurality of blind holes are arranged in the middle of an outer side wall of the shaft pin. Foil gauges are adhered in the blind holes. An annular groove is arranged in the outer side wall of the shaft pin. The annular groove goes through circle centers of the blind holes. And a cable is connected to the end of the shaft pin.
Description
Technical field
The utility model relates to a kind of sensor, more specifically to a kind of axial pin type sensor.
Technical background
Axial pin type sensor has embodied electronic scale miniaturization, modularization, integrated, intelligentized developing direction, is a kind of integrated morphology that carrier and LOAD CELLS are united two into one, and is to measure the radial load of members such as bearing, pulley or the sensor special of steel wire rope tension; Mainly be that the axle or the other forms of bearing pin that substitute equalizer pulley, fixed pulley is installed in and does radial force in the structure and measure; The Chinese patent notification number is CN2450647Y, and the day for announcing is that the name of the utility model in September 26 calendar year 2001 is called dynamic shaft pin formula force cell, comprises pivot pin; On this pivot pin, be provided with the orthogonal Wheatstone bridge strain-gauge transducer of induction sensitive direction simultaneously; Though above-mentioned utility model all counts the acting force of both direction, reduced the detection error, foil gauge is but away from the center of effort of pivot pin; The pressure that sensor is received also decreases; And then reduced accuracy of detection, and pivot pin is not elastic body, reduced deformability and reduced accuracy of detection yet.
Summary of the invention
The purpose of the utility model is to overcome the existing low technical barrier of axial pin type sensor accuracy of detection, provides a kind of simple in structure, easy for installation, the axial pin type sensor that accuracy of detection is high.
The utility model solves through following technical proposals, and a kind of axial pin type sensor comprises pivot pin; Described pivot pin integral body is elastic body; The lateral wall middle part of said pivot pin is provided with several blind holes, is pasted with foil gauge in the described blind hole, and described pivot pin lateral wall is provided with annular groove; Described annular groove is by way of the center of circle of blind hole, and described pivot pin end is connected with cable.Through position that foil gauge is attached more near the stress point of pivot pin; More directly pressure is passed to foil gauge, also have annular groove at the blind hole place simultaneously, improved the deformability of pivot pin when receiving radial force; And then improved accuracy of detection; The utility model is simple in structure, and is easy for installation, and changes easily in impaired back.
As preferably, described annular groove has two and be parallel to each other, and described blind hole has four, and four blind holes are rectangle and arrange.A plurality of foil gauges raising accuracy of detection of working simultaneously.
As preferably, described pivot pin end is provided with draw-in groove.Prevent that pivot pin from when work, rotating owing to receiving radial force.
As preferably, described pivot pin front end is provided with through hole.Through through hole pivot pin is limited on the equipment, prevents that pivot pin is moved when stressed, and then come off.
As preferably, described cable is connected with pivot pin through water joint.Water joint plays waterproof, anti-wet goods effect.
Therefore, a kind of axial pin type sensor of the utility model possesses following beneficial effect: simple in structure, easy for installation, strain makes pressure better pass to foil gauge near stress point, has also improved the deformability of pivot pin simultaneously, and then improves accuracy of detection.

Embodiment
Pass through embodiment below, and combine accompanying drawing, the utility model is further explained.
Embodiment: like Fig. 1, shown in Figure 2, a kind of axial pin type sensor comprises pivot pin 1; Pivot pin 1 integral body is elastic body, and elastic deformation can take place, and has four blind holes at the lateral wall middle part of pivot pin 1; Four blind holes are rectangle and arrange, and in blind hole, are pasted with foil gauge 2, make foil gauge 2 more near middle stress point; And then make pivot pin 1 suffered pressure more directly pass to foil gauge 2, and improved accuracy of detection, the while also has two annular grooves 3 and is parallel to each other on the lateral wall of pivot pin 1; Each annular groove 3 is by way of two centers with respect to the axisymmetric blind hole in pivot pin 1 center; Dwindled the diameter of foil gauge 2 place's pivot pins 1, improved the deformability of pivot pin 1, and then improved accuracy of detection.End at pivot pin 1 has draw-in groove 4; Rotate after avoiding pivot pin 1 to install; Thereby influence accuracy of detection, have through hole 5 at the front end of pivot pin 1, through hole 5 is vertical with the central shaft of pivot pin 1; Can pivot pin 1 be limited on the equipment through through hole 5, prevent to come off because pivot pin 1 is in use stressed.End at pivot pin 1 is connected with cable 7 through water joint 6, and water joint 6 can play waterproof effect.
Axial pin type sensor can substitute the axle or the other forms of bearing pin of equalizer pulley, fixed pulley, is used to detect the radial force on the pivot pin 1, when pivot pin 1 receives radial force; Pivot pin 1 deforms; And then racking strain sheet 2, pressure is passed to foil gauge 2, thus the radial force of detecting.
