Abstract

The utility model discloses an electric barrel-roll scale capable of measuring applied force of a rotator. The electric barrel-roll scale comprises a spline shaft connected with an inner gear disk and a conductive slip ring, a sensor connecting support and a Junction box are fixedly connected on the outside of the inner gear disk, a sensor is fixedly connected on the sensor connecting support through a dowel, a barrel-roll felloe is fixedly connected on the outside of the sensor, and a sensing sheet is installed on the sensor. The number of sensors is at least three, therefore, no matter which direction a force is from, it can be measured by the sensor. The power supply and signal output of the sensor are all realized through the conductive slip ring, therefore, electricity and signal transmission can all be realized for measuring the applied force when the barrel-roll felloe is rotating.

Description

Electronic rotary drum scale
Technical field
The utility model relates to a kind of force measurement sensing device, relates in particular to a kind of electronic rotary drum scale.
Background technology
The surperficial stressed size of rotors such as the gear that uses, drum can't realize rotating and measure at present, and the measurement of traditional rotor adopts the bed knife sensor to measure, some torque surveying instruments also are to adopt the bed knife sensor to measure the size of torque, can't realize the measurement of the stressed size of rotor.
Summary of the invention
The purpose of this utility model provides the electronic rotary drum scale of the stressed size of a kind of energy measurement rotor.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of electronic rotary drum scale, comprise the key axle, it is characterized in that: fluted disc and conducting slip ring in being connected with on the key axle, interior fluted disc external fixation is connected with sensor and connects bearing and terminal box, be fixedly connected with sensor by pin on the sensor connection bearing, the sensor external fixation is connected with the drum foreign steamer, and sensing chip is housed on the sensor.
According to described electronic rotary drum scale, it is characterized in that: the quantity of described sensor is at least three.
The minimum number of sensor is three in the utility model, and like this, no matter stressed from which direction, sensor can both measure.The power supply of sensor is supplied with signal output and is realized by conducting slip ring that all the drum foreign steamer also can be realized the transmission of power supply and signal when rotating like this, measures stressed size.Sensor is that rotating dog connects with being connected of interior fluted disc, the inside fluted disc direction of sensor connects seat supports by sensor, sensor can rotate to drum foreign steamer direction, has two sensors to have signal to pass to terminal box so all the time, and can not produce designature because of the reversal deformation of another sensor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an another kind of structural representation of the present utility model.
In the accompanying drawing:
1, drum foreign steamer 2, sensor 3, sensing chip 4, sensor connect bearing 5, pin 6, interior fluted disc 7, terminal box 8, conducting slip ring
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
A kind of electronic rotary drum scale, as shown in Figure 1 and Figure 2, comprise the key axle, fluted disc 6 and conducting slip ring 8 in being connected with on the key axle, interior fluted disc 6 external fixation are connected with sensor and connect bearing 4 and terminal box 7, be fixedly connected with sensor 2 by pin 5 on the sensor connection bearing 4, sensor 2 external fixation are connected with drum foreign steamer 1, and sensing chip 3 is housed on the sensor 2.In the present embodiment, the quantity of sensor 2 is at least three.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineering technical personnel make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
In the utility model, the rotation center of interior fluted disc and drum foreign steamer is on same axis, link together by sensor, the putting position of sensor is that sensing chip and the interior fluted disc center of circle on the sensor is parallel with the tangent line of the intersection point of drum foreign steamer to drum foreign steamer radius, and this radius is vertical with sensing chip on the sensor.The outside of fluted disc in terminal box is fixed on, conducting slip ring and interior fluted disc are enclosed within on the key axle (or splined shaft), external power source enters sensor by conducting slip ring, terminal box, and the signal of sensor enters the dynamometry instrument of weighing by terminal box, conducting slip ring, shows the stressed size of current drum.
In the utility model, the minimum number of sensor is three, when the height of drum foreign steamer reaches three sensors and can not accurately measure, need to be equipped with respectively the device of sensor, interior fluted disc, terminal box, conducting slip ring at two of drum foreign steamer, the shared dynamometry instrument of weighing, the minimum number of sensor is six like this.
Because the minimum number of the utility model sensor is three, like this, sensor can measure the power that applies from all directions, and has two all the time to the terminal box input signal in three sensors.The power supply of sensor is supplied with signal output and is all realized by conducting slip ring.Sensor realizes that with being connected with rotating dog of interior fluted disc the inside fluted disc direction of sensor connects seat supports by sensor, and sensor can rotate to drum foreign steamer direction.
Power supply of the present utility model and signal are all imported, are exported by conducting slip ring, after arbitrary position of the drum foreign steamer that rotates is stressed, three sensors have two sensors stressed all the time, alternately signal are passed to terminal box, have a sensor alternately not stress all the time; Because of sensor is fixedlyed connected with the drum foreign steamer, it is to connect with rotating dog that sensor is connected with interior fluted disc, the inside fluted disc direction of sensor connects seat supports by sensor, sensor can rotate to drum foreign steamer direction, so, all the time the sensor that does not alternately stress is output signal not, has all the time that two sensors 2 are stressed alternately to pass to terminal box 7 with signal, and terminal box 7 passes to the dynamometry instrument of weighing with signal by conducting slip ring 8.
