Abstract
The invention provides a friction measuring device for a swinging gemel and includes a supporter. The upward side of the supporter is provided with a bearing seat and two force sensors. A motor is arranged below the supporter. An output shaft of the motor is fixedly connected with a curved shaft and the other end of the curved shaft extends to a pin roll in a sliding slot on an oscillating arm. The other end of the oscillating arm is arranged on the bearing seat through an oscillating arm rotary shaft. The swinging side of the gemel is fixedly connected with the oscillating arm and is fixedly connected with a gemel rotary shaft. The measuring side of the gemel is arranged on the gemel rotary shaft. The measuring heads of the two force sensors are respectively extruded at two sides of the measuring side of the gemel. When the invention is used for measuring the friction, as the measuring side of the gemel does not move, the inertia force is not affected. The moment measured by the sensor is the friction moment of the gemel and the measuring result is accurate. The structure of the device is simple and the measuring is convenient.
Description
(1) technical field
What the present invention relates to is a kind of force measurement device, specifically at a kind of swinging movement hinge friction measurement device.
(2) background technology
In general friction force all can not be ignored the influence of mechanism kinematic, therefore, is very necessary to the friction force measurement of various mechanisms.But because a variety of causes, friction force also is a difficult point of measuring always.
At present a lot of to the method for friction measurement, but be directed to different mechanisms, measuring method is also different with device.For example number of patent application is 200520102383.X, and name is called the friction force of bearing under tiny load measurement mechanism, the utility application file in disclosed technical scheme, can accurately measure the friction force and the friction factor of sliding bearing and rolling bearing.But also do not retrieve the isolated plant that swinging movement hinge friction is measured at present.It is a kind of method commonly used that utilization makes the measurement of the moment of hinge uniform rotation come the friction force of indirect derivation hinge, but this measuring method is comparatively indirect, will inevitably influence measuring accuracy, and the method just can't be measured for swing hinge.Accurate measuring method is the tangential force of two surface of contact during by the sensor measurement hinge movement, but sensor complex, it is big to measure difficulty.
(3) summary of the invention
The object of the present invention is to provide a kind of measurement result accurate, simple in structure, measure swinging movement hinge friction measurement device easily.
The object of the present invention is achieved like this: it comprises support, bearing seat and two force transducers are installed above support, motor is installed below support, be fixed with bent axle on the output shaft of motor, the other end of bent axle has and extend into a bearing pin in the chute in the swing arm, the other end of swing arm is installed on the bearing seat by the swing arm rotating shaft, the swing side of hinge and swing arm is connected and the swing side of hinge on be fixed with the hinge turning axle, the measurement side of hinge is installed on the hinge turning axle, the swing arm rotating shaft overlaps with the rotation of hinge turning axle, and the measuring head of two force transducers is squeezed in the both sides that hinge is measured side respectively.
The present invention can also comprise:
1, right alignment is installed and indicates arm above support.
Whether the right alignment among the present invention indicates arm is to be used for identifying swing arm to overlap with the rotation of hinge; Bearing seat supports the rotating shaft of swing arm; The swing side of swing arm and hinge is fixed; The swing side of hinge and the bearing pin of hinge are fixed; When hinge is installed, guarantee that the rotation of swing arm and the rotation of hinge overlap, but two turning axles separate; Pressure transducer is fixed on the support, and its measuring head is squeezed in the both sides that hinge is measured side respectively; Motor and crank are fixed, and an end of crank slides in the chute of swing arm, and when motor rotated, the crank turnover was swung thereby drive swing arm like this.
During measurement, at first the swing side with hinge is fixed in the swing arm, when the axle center of turning axle of hinge is pointed at the tip that right alignment indicates arm, represents that promptly hinge overlaps with the rotation of swing arm.After the hinge installation, regulate the position of two force transducers, make it be squeezed in the both sides that hinge is measured side, pressure transducer produces certain force value.Actuating motor, motor rotates, and drives crank and rotates, thereby impel swing arm to swing.Swing arm drives the swing side of hinge and swings, because the coincidence of the rotation of the rotation of swing arm and hinge, so the swing side of hinge also is to swing around self axis, if there is not friction force like this, the measurement side of hinge is not rotated.Because the bearing pin of hinge is measured side with hinge the friction force effect is arranged, so during hinge swing lateral movement, will impose on hinge measurement side one moment of friction, thereby the measurement side of hinge will produce movement tendency.Because hinge is measured the both sides of side and is being pushed force transducer, though though therefore the measurement side of hinge do not swing, its suffered moment of friction will with the branch counter moment balance of sensor, so just can measure the moment of friction of hinge.
The present invention is when measuring friction force, because the not motion of the measurement side of hinge, so not influence of inertial force.The moment that sensor is measured is the moment of friction of hinge, and measurement result is accurate.That installs is simple in structure, and it is convenient to measure.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
(5) embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1 and Fig. 2, the composition of swinging movement hinge friction measurement device comprises that support 1, right alignment indicate arm 2, bearing seat 3, pressure transducer 4 and 5, the swing side 6 of hinge, measurement side 7, swing arm 8, crank 9 and the motor 10 of hinge; Wherein, whether right alignment sign arm 2 is to be used for identifying swing arm 8 to overlap with the rotation of hinge; Bearing seat 3 supports the rotating shaft of swing arm 8; Swing arm 8 is fixing with the swing side 6 of hinge; When hinge is installed, guarantee that the rotation of swing arm 8 and the rotation of hinge overlap, but two turning axles separate; Pressure transducer 4 and 5 is fixed on the support 1, and its measuring head is squeezed in the both sides that hinge is measured side 7 respectively; Motor 10 is fixing with crank 9, and an end of crank 9 slides in the chute of swing arm 8, and when motor 10 rotated, crank 9 had enough to meet the need like this, thereby drives swing arm 8 swings.
During measurement, at first the swing side 6 with hinge is fixed in the swing arm 8, when the axle center of turning axle of hinge is pointed at the tip that right alignment indicates arm 2, represents that promptly hinge overlaps with the rotation of swing arm 8.After the hinge installation, regulate the position of sensor 4 and 5, make it be squeezed in the both sides that hinge is measured side 7, pressure transducer 4 and 5 produces certain force value.Actuating motor 10, motor rotates, and drives crank 9 and rotates, thereby impel swing arm 8 to swing.Swing arm 8 drives the swing side 6 of hinges and swings, because the coincidence of the rotation of the rotation of swing arm 8 and hinge, so the swing side 6 of hinge also is to swing around self axis, if there is not friction force like this, the measurement side 7 of hinge is not rotated.Because the bearing pin of hinge is measured side 7 with hinge the friction force effect is arranged, so during 6 motions of hinge swing side, will impose on hinge measurement side 7 one moment of frictions, thereby the measurement side 6 of hinge will produce movement tendency.Because hinge is measured the both sides of side 7 and is being pushed force transducer 4 and 5, though though therefore the measurement side of hinge do not swing, its suffered moment of friction will with the branch counter moment balance of sensor, so just can measure the moment of friction of hinge.
